+
+# /graphify
+
+Turn any folder of files into a navigable knowledge graph with community detection, an honest audit trail, and three outputs: interactive HTML, GraphRAG-ready JSON, and a plain-language GRAPH_REPORT.md.

+
+## What graphify is for
+
+Drop any folder of code, docs, papers, images, or video into graphify and get a queryable knowledge graph. Persistent across sessions, honest audit trail (EXTRACTED/INFERRED/AMBIGUOUS), community detection surfaces cross-document connections you wouldn't think to ask about.
+
+## What You Must Do When Invoked
+
+If the user invoked `/graphify --help` or `/graphify -h` (with no other arguments), print the contents of the `## Usage` section above verbatim and stop. Do not run any commands, do not detect files, do not default the path to `.`. Just print the Usage block and return.
+
+**Fast path — existing graph:** Before doing anything else, check whether `graphify-out/graph.json` exists. The expected location is `graphify-out/graph.json` relative to the **current working directory** (i.e. the project root where you are running commands). If it exists AND the user's request is a natural-language question about the codebase (e.g. "How does X work?", "What calls Y?", "Trace the data flow through Z") and NOT an explicit rebuild command (`--update`, `--cluster-only`, or a bare path/URL that implies fresh extraction): **skip Steps 1–5 entirely and jump straight to `## For /graphify query`.** Run `graphify query "<question>"` immediately. Do not run detect. Do not check corpus size. Do not ask the user to narrow. The graph is already built — use it.
+
+If no path was given, use `.` (current directory). Do not ask the user for a path.
+
+If the path argument starts with `https://github.com/` or `http://github.com/`, treat it as a GitHub URL - run Step 0 before anything else, then continue with the resolved local path.
+
+Follow these steps in order. Do not skip steps.
+
+### Step 0 - GitHub repos and multi-path merge (only if a URL or several paths)
+
+Only when the path is one or more `https://github.com/...` URLs, or several local subfolders to merge. See `references/github-and-merge.md` for the clone, cross-repo merge, and monorepo flow, then continue with the resolved local path. A plain local path skips this step.
+
+### Step 1 - Ensure graphify is installed
+
+```bash
+# Detect the correct Python interpreter (handles uv tool, pipx, venv, system installs)
+PYTHON=""
+GRAPHIFY_BIN=$(which graphify 2>/dev/null)
+# 1. uv tool installs — most reliable on modern Mac/Linux
+if [ -z "$PYTHON" ] && command -v uv >/dev/null 2>&1; then
+    _UV_PY=$(uv tool run --from graphifyy python -c "import sys; print(sys.executable)" 2>/dev/null)
+    if [ -n "$_UV_PY" ]; then PYTHON="$_UV_PY"; fi
+fi
+# 2. Read shebang from graphify binary (pipx and direct pip installs)
+if [ -z "$PYTHON" ] && [ -n "$GRAPHIFY_BIN" ]; then
+    _SHEBANG=$(head -1 "$GRAPHIFY_BIN" | tr -d '#!')
+    case "$_SHEBANG" in
+        *[!a-zA-Z0-9/_.@-]*) ;;
+        *) "$_SHEBANG" -c "import graphify" 2>/dev/null && PYTHON="$_SHEBANG" ;;
+    esac
+fi
+# 3. Fall back to python3
+if [ -z "$PYTHON" ]; then PYTHON="python3"; fi
+if ! "$PYTHON" -c "import graphify" 2>/dev/null; then
+    if command -v uv >/dev/null 2>&1; then
+        uv tool install --upgrade graphifyy -q 2>&1 | tail -3
+        _UV_PY=$(uv tool run --from graphifyy python -c "import sys; print(sys.executable)" 2>/dev/null)
+        if [ -n "$_UV_PY" ]; then PYTHON="$_UV_PY"; fi
+    else
+        "$PYTHON" -m pip install graphifyy -q 2>/dev/null \
+          || "$PYTHON" -m pip install graphifyy -q --break-system-packages 2>&1 | tail -3
+    fi
+fi
+# Write interpreter path for all subsequent steps (persists across invocations)
+mkdir -p graphify-out
+"$PYTHON" -c "import sys; open('graphify-out/.graphify_python', 'w', encoding='utf-8').write(sys.executable)"
+# Save scan root so `graphify update` (no args) knows where to look next time
+echo "$(cd INPUT_PATH && pwd)" > graphify-out/.graphify_root
+```
+
+If the import succeeds, print nothing and move straight to Step 2.
+
+**In every subsequent bash block, replace `python3` with `$(cat graphify-out/.graphify_python)` to use the correct interpreter.**
+
+### Step 2 - Detect files
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from graphify.detect import detect
+from pathlib import Path
+result = detect(Path('INPUT_PATH'))
+print(json.dumps(result, ensure_ascii=False))
+" > graphify-out/.graphify_detect.json
+```
+
+Replace INPUT_PATH with the actual path the user provided. Do NOT cat or print the JSON - read it silently and present a clean summary instead:
+
+```
+Corpus: X files · ~Y words
+  code:     N files (.py .ts .go ...)
+  docs:     N files (.md .txt ...)
+  papers:   N files (.pdf ...)
+  images:   N files
+  video:    N files (.mp4 .mp3 ...)
+```
+
+Omit any category with 0 files from the summary.
+
+Then act on it:
+- If `total_files` is 0: stop with "No supported files found in [path]."
+- If `skipped_sensitive` is non-empty: report the count and list the skipped file names, so a wrongly-flagged source or doc is visible and can be renamed or moved (#2106).
+- If `total_words` > 2,000,000 OR `total_files` > 500: show the warning. Then compute the top 5 first-level subdirectories by file count:
+  - Read `scan_root` from the detect JSON (always an absolute path to the resolved INPUT_PATH).
+  - Concatenate all file lists across all types (`code`, `document`, `paper`, `image`, `video`).
+  - Filter out any path that starts with `scan_root + "/graphify-out/"` to exclude converted sidecars.
+  - For each file, strip the `scan_root` prefix and take the first path component. Files directly in `scan_root` with no subdirectory count as `(root)`.
+  - If all files are in `(root)` with no subdirectories, do not ask to narrow — no subfolders exist. Instead suggest `--no-cluster` to skip the expensive clustering step and proceed.
+  - Otherwise rank by count, show the top 5 with file counts, then ask which subfolder to run on. Wait for the user's answer before proceeding.
+- Otherwise: proceed directly to Step 2.5 if video files were detected, or Step 3 if not.
+
+### Step 2.5 - Video and audio (only if video files detected)
+
+Skip this step entirely if `detect` returned zero `video` files. When the corpus has video or audio, see `references/transcribe.md` to transcribe them to text first, then treat the transcripts as doc files in Step 3.
+
+### Step 3 - Extract entities and relationships
+
+**Before starting:** note whether `--mode deep` was given. You must pass `DEEP_MODE=true` to every subagent in Step B2 if it was. Track this from the original invocation - do not lose it.
+
+This step has two parts: **structural extraction** (deterministic, free) and **semantic extraction** (LLM, costs tokens).
+
+> **graphify needs no API key. Never ask the user for one, and never block on one.** Code is extracted structurally (AST) with no LLM and no key at all — a code-only corpus (the common `/graphify .` on a repo) skips semantic extraction entirely, so it needs nothing here: go straight to Part A and skip Part B. Semantic extraction (only for docs, papers, and images) uses Gemini **only if** `GEMINI_API_KEY`/`GOOGLE_API_KEY` is already set; otherwise the host agent itself is the LLM. graphify does **not** read `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, or any other provider key. If you catch yourself about to prompt for, wait on, or stop because of a missing API key, that is a misread of this skill — proceed without one.
+
+**Before semantic extraction:** check whether `GEMINI_API_KEY` or `GOOGLE_API_KEY` is set. If neither is set, print this one-liner to the user:
+> Tip: set `GEMINI_API_KEY` or `GOOGLE_API_KEY` to use Gemini for semantic extraction (`pip install 'graphifyy[gemini]'`).
+
+Print it once, then continue — do not wait for the user to supply a key. If `GEMINI_API_KEY` or `GOOGLE_API_KEY` IS set, use `graphify.llm.extract_corpus_parallel(files, backend="gemini")` for semantic extraction instead of dispatching subagents. The default Gemini model is `gemini-3-flash-preview`; set `GRAPHIFY_GEMINI_MODEL` or pass `--model` in headless CLI flows to override it.
+
+> **No other API keys are read.** When `GEMINI_API_KEY`/`GOOGLE_API_KEY` are unset, semantic extraction falls to the host agent itself — the running session is the LLM. On a host that dispatches subagents (e.g. Claude Code), dispatch them as written in Part B. On a host that runs the CLI directly in a terminal and cannot dispatch subagents, do not stall: a code-only corpus has no semantic work, so write the empty semantic file (Part B "Fast path") and continue to Part C; for a corpus with docs/papers/images, either set a Gemini key or extract those inline yourself, but in no case prompt for `ANTHROPIC_API_KEY` — that prompt is a misread of this skill.
+
+**Run Part A (AST) and Part B (semantic) in parallel. Dispatch all semantic subagents AND start AST extraction in the same message. Both can run simultaneously since they operate on different file types. Merge results in Part C as before.**
+
+Note: Parallelizing AST + semantic saves 5-15s on large corpora. AST is deterministic and fast; start it while subagents are processing docs/papers.
+
+#### Part A - Structural extraction for code files
+
+For any code files detected, run AST extraction in parallel with Part B subagents:
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import sys, json
+from graphify.extract import collect_files, extract
+from pathlib import Path
+import json
+
+code_files = []
+detect = json.loads(Path('graphify-out/.graphify_detect.json').read_text(encoding=\"utf-8\"))
+for f in detect.get('files', {}).get('code', []):
+    code_files.extend(collect_files(Path(f)) if Path(f).is_dir() else [Path(f)])
+
+if code_files:
+    result = extract(code_files, cache_root=Path('INPUT_PATH'))
+    Path('graphify-out/.graphify_ast.json').write_text(json.dumps(result, indent=2, ensure_ascii=False), encoding=\"utf-8\")
+    print(f'AST: {len(result[\"nodes\"])} nodes, {len(result[\"edges\"])} edges')
+else:
+    Path('graphify-out/.graphify_ast.json').write_text(json.dumps({'nodes':[],'edges':[],'input_tokens':0,'output_tokens':0}, ensure_ascii=False), encoding=\"utf-8\")
+    print('No code files - skipping AST extraction')
+"
+```
+
+#### Part B - Semantic extraction (parallel subagents)
+
+**Fast path:** If detection found zero docs, papers, and images (code-only corpus), skip Part B entirely and go straight to Part C. AST handles code - there is nothing for semantic subagents to do. **First write an empty semantic file** so Part C's merge has its input (it reads `.graphify_semantic.json` unconditionally; without this a code-only run hits `FileNotFoundError`):
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from pathlib import Path
+Path('graphify-out/.graphify_semantic.json').write_text(json.dumps({'nodes':[],'edges':[],'hyperedges':[],'input_tokens':0,'output_tokens':0}), encoding='utf-8')
+"
+```
+
+**MANDATORY: You MUST use the Agent tool here. Reading files yourself one-by-one is forbidden - it is 5-10x slower. If you do not use the Agent tool you are doing this wrong.**
+
+Before dispatching subagents, print a timing estimate:
+- Load `total_words` and file counts from `graphify-out/.graphify_detect.json`
+- Estimate agents needed: `ceil(uncached_non_code_files / 22)` (chunk size is 20-25)
+- Estimate time: ~45s per agent batch (they run in parallel, so total ≈ 45s × ceil(agents/parallel_limit))
+- Print: "Semantic extraction: ~N files → X agents, estimated ~Ys"
+
+**Step B0 - Check extraction cache first**
+
+Before dispatching any subagents, check which files already have cached extraction results:
+
+SPEC_PATH below is the **absolute** path of the `references/extraction-spec.md` that ships beside this SKILL.md — the same file Step B2 loads and hands to every subagent. It is the extraction prompt, so cache entries are attributed to it: when a graphify upgrade changes the prompt, entries produced by the old one are re-extracted instead of replayed, and unchanged prompts keep their entries (#1939). Substitute the real path in both Step B0 and Step B3 — pass the same one to each, and do not drop the argument.
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from graphify.cache import check_semantic_cache
+from pathlib import Path
+
+detect = json.loads(Path('graphify-out/.graphify_detect.json').read_text(encoding=\"utf-8\"))
+# Only content files go to semantic extraction. Code is already covered structurally
+# by the AST pass (Part A); flattening every category here makes subagents re-read
+# every source file (#1392). Video is transcribed to a document in Step 2.5 first.
+all_files = [f for cat in ('document', 'paper', 'image') for f in detect['files'].get(cat, [])]
+
+cached_nodes, cached_edges, cached_hyperedges, uncached = check_semantic_cache(all_files, root='INPUT_PATH', prompt_file='SPEC_PATH')
+
+# Always (re)write the cache file: write hits, else DELETE any leftover from a prior
+# run so Part C never merges a stale .graphify_cached.json (#1392).
+if cached_nodes or cached_edges or cached_hyperedges:
+    Path('graphify-out/.graphify_cached.json').write_text(json.dumps({'nodes': cached_nodes, 'edges': cached_edges, 'hyperedges': cached_hyperedges}, ensure_ascii=False), encoding=\"utf-8\")
+else:
+    Path('graphify-out/.graphify_cached.json').unlink(missing_ok=True)
+Path('graphify-out/.graphify_uncached.txt').write_text('\n'.join(uncached), encoding=\"utf-8\")
+print(f'Cache: {len(all_files)-len(uncached)} files hit, {len(uncached)} files need extraction')
+"
+```
+
+Only dispatch subagents for files listed in `graphify-out/.graphify_uncached.txt`. If all files are cached, skip to Part C directly.
+
+**Step B1 - Split into chunks**
+
+Load files from `graphify-out/.graphify_uncached.txt`. Split into chunks of 20-25 files each. Each image gets its own chunk (vision needs separate context). When splitting, group files from the same directory together so related artifacts land in the same chunk and cross-file relationships are more likely to be extracted.
+
+**Step B2 - Dispatch ALL subagents in a single message (OpenCode)**
+
+> **OpenCode platform:** Uses `@mention` dispatch instead of the Agent tool. All mentions in a single message run in parallel.
+
+Dispatch one `@mention` per chunk — ALL in the same response:
+
+```
+@agent Chunk CHUNK_NUM of TOTAL_CHUNKS: [extraction prompt with FILE_LIST, CHUNK_NUM, TOTAL_CHUNKS, DEEP_MODE substituted]
+
+@agent Chunk 2 of TOTAL_CHUNKS: [next chunk]
+```
+
+Wait for all agents to return. Parse each response as JSON. Accumulate nodes/edges/hyperedges across all results and write to `graphify-out/.graphify_semantic_new.json`. If the `@agent` path cannot write chunk files, fall back to the serial path that writes each `graphify-out/.graphify_chunk_NN.json` before merge.
+
+Subagent prompt template:
+
+See `references/extraction-spec.md` for the exact subagent prompt (JSON schema, node-ID rules, confidence rubric, hyperedge, and vision rules). Load it only here, only when at least one chunk holds a doc, paper, or image; a pure-code corpus has skipped Part B and never reads it. Pass each agent that prompt verbatim with FILE_LIST, CHUNK_NUM, TOTAL_CHUNKS, and DEEP_MODE substituted.
+
+**Step B3 - Collect, cache, and merge**
+
+Wait for all subagents. For each result:
+- Check that `graphify-out/.graphify_chunk_NN.json` exists on disk — this is the success signal
+- If the file exists and contains valid JSON with `nodes` and `edges`, include it and save to cache
+- If the file is missing, the subagent was likely dispatched as read-only (Explore type) — print a warning: "chunk N missing from disk — subagent may have been read-only. Re-run with general-purpose agent." Do not silently skip.
+- If a subagent failed or returned invalid JSON, print a warning and skip that chunk - do not abort
+
+If more than half the chunks failed or are missing, stop and tell the user to re-run and ensure `subagent_type="general-purpose"` is used.
+
+Merge all chunk files into `.graphify_semantic_new.json`. **After each Agent call completes, read the real token counts from the Agent tool result's `usage` field and write them back into the chunk JSON before merging** — the chunk JSON itself always has placeholder zeros. Then run:
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json, glob
+from pathlib import Path
+
+chunks = sorted(glob.glob('graphify-out/.graphify_chunk_*.json'))
+all_nodes, all_edges, all_hyperedges = [], [], []
+total_in, total_out = 0, 0
+for c in chunks:
+    d = json.loads(Path(c).read_text(encoding=\"utf-8\"))
+    all_nodes += d.get('nodes', [])
+    all_edges += d.get('edges', [])
+    all_hyperedges += d.get('hyperedges', [])
+    total_in += d.get('input_tokens', 0)
+    total_out += d.get('output_tokens', 0)
+Path('graphify-out/.graphify_semantic_new.json').write_text(json.dumps({
+    'nodes': all_nodes, 'edges': all_edges, 'hyperedges': all_hyperedges,
+    'input_tokens': total_in, 'output_tokens': total_out,
+}, indent=2, ensure_ascii=False), encoding=\"utf-8\")
+print(f'Merged {len(chunks)} chunks: {total_in:,} in / {total_out:,} out tokens')
+"
+```
+
+Save new results to cache. Pass the same SPEC_PATH as Step B0 — it stamps each entry with the prompt that produced it, and a write under a different prompt than the read lands where the next run won't look (#1939):
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from graphify.cache import save_semantic_cache

+### Step 4 - Build graph, cluster, analyze, generate outputs
+
+**Before starting:** the code blocks below pass `directed=IS_DIRECTED` to `build_from_json()`. Replace `IS_DIRECTED` with `True` if `--directed` was given (builds a `DiGraph` preserving edge direction source→target), otherwise `False` (the default undirected `Graph`). Substitute it the same way you substitute `INPUT_PATH` — do not leave the literal `IS_DIRECTED` in the code.
+
+```bash
+mkdir -p graphify-out
+$(cat graphify-out/.graphify_python) -c "
+import sys, json
+from graphify.build import build_from_json
+from graphify.cluster import cluster, score_all
+from graphify.analyze import god_nodes, surprising_connections, suggest_questions
+from graphify.report import generate
+from graphify.export import to_json
+from pathlib import Path
+
+extraction = json.loads(Path('graphify-out/.graphify_extract.json').read_text(encoding=\"utf-8\"))
+detection  = json.loads(Path('graphify-out/.graphify_detect.json').read_text(encoding=\"utf-8\"))
+
+# root= mirrors the --update runbook (#1361): relativize source_file to the same
+# base so the full build and incremental --update never drift apart on re-extract.
+G = build_from_json(extraction, root='INPUT_PATH', directed=IS_DIRECTED)
+# Guard BEFORE any write: an empty extraction must not clobber a good graph.json /
+# GRAPH_REPORT.md / analysis sidecar. Check immediately after build (#1392).
+if G.number_of_nodes() == 0:
+    print('ERROR: Graph is empty - extraction produced no nodes.')
+    print('Possible causes: all files were skipped, binary-only corpus, or extraction failed.')
+    raise SystemExit(1)
+communities = cluster(G)
+cohesion = score_all(G, communities)
+tokens = {'input': extraction.get('input_tokens', 0), 'output': extraction.get('output_tokens', 0)}
+gods = god_nodes(G)
+surprises = surprising_connections(G, communities)
+labels = {cid: 'Community ' + str(cid) for cid in communities}
+# Placeholder questions - regenerated with real labels in Step 5
+questions = suggest_questions(G, communities, labels)
+
+# Export FIRST and honor the #479 shrink-guard: to_json returns False (writing
+# nothing) when the new graph is smaller than the existing graph.json. Only write
+# GRAPH_REPORT.md + the analysis sidecar when the graph was actually written, so
+# they never describe a graph that graph.json doesn't contain (#1392).
+wrote = to_json(G, communities, 'graphify-out/graph.json')
+if not wrote:
+    print('ERROR: refused to shrink graphify-out/graph.json (existing graph has more nodes; #479).')
+    print('If this shrink is intentional (you deleted files), re-run a full build with --force.')
+    raise SystemExit(1)
+report = generate(G, communities, cohesion, labels, gods, surprises, detection, tokens, 'INPUT_PATH', suggested_questions=questions)
+Path('graphify-out/GRAPH_REPORT.md').write_text(report, encoding=\"utf-8\")
+analysis = {
+    'communities': {str(k): v for k, v in communities.items()},
+    'cohesion': {str(k): v for k, v in cohesion.items()},

+    'questions': questions,
+}

+print(f'Graph: {G.number_of_nodes()} nodes, {G.number_of_edges()} edges, {len(communities)} communities')
+"
+```
+
+If this step prints `ERROR: Graph is empty`, stop and tell the user what happened - do not proceed to labeling or visualization.
+
+Replace INPUT_PATH with the actual path.
+
+### Step 4.5 - Graph health check (read-only integrity gate)
+
+A non-destructive diagnostic on the extraction, before labeling. It surfaces edge collapse, dangling/missing endpoints, and self-loops — the silent-corruption modes of incremental updates and AST/LLM id mismatches. Read-only; never aborts.
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from pathlib import Path
+from graphify.diagnostics import diagnose_extraction, format_diagnostic_report
+
+extraction = json.loads(Path('graphify-out/.graphify_extract.json').read_text(encoding=\"utf-8\"))
+summary = diagnose_extraction(extraction, directed=IS_DIRECTED, root='INPUT_PATH')
+print(format_diagnostic_report(summary))
+flags = [f'{summary[k]} {label}' for k, label in (
+    ('dangling_endpoint_edges', 'dangling-endpoint edges'),
+    ('missing_endpoint_edges', 'missing-endpoint edges'),
+    ('self_loop_edges', 'self-loop edges'),
+    ('directed_same_endpoint_collapsed_edges', 'collapsed (directed) edges'),
+    ('undirected_same_endpoint_collapsed_edges', 'collapsed (undirected) edges'),
+) if summary.get(k, 0)]
+print('GRAPH HEALTH WARNING: ' + '; '.join(flags) + ' - graph may be incomplete/corrupt.' if flags else 'Graph health: OK (no dangling/missing/collapsed edges).')
+"
+```
+
+Substitute `IS_DIRECTED` and `INPUT_PATH` as in Step 4. If a `GRAPH HEALTH WARNING` prints, surface it in the final summary (do not abort — the graph is still usable, but the integrity issue must be visible, per the Honesty Rules).
+
+### Step 5 - Label communities
+
+Read `graphify-out/.graphify_analysis.json`. For each community key, look at its node labels and write a 2-5 word plain-language name (e.g. "Attention Mechanism", "Training Pipeline", "Data Loading").
+
+Then regenerate the report and save the labels for the visualizer:
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import sys, json
+from graphify.build import build_from_json
+from graphify.cluster import score_all
+from graphify.analyze import god_nodes, surprising_connections, suggest_questions
+from graphify.report import generate
+from pathlib import Path
+
+extraction = json.loads(Path('graphify-out/.graphify_extract.json').read_text(encoding=\"utf-8\"))
+detection  = json.loads(Path('graphify-out/.graphify_detect.json').read_text(encoding=\"utf-8\"))
+analysis   = json.loads(Path('graphify-out/.graphify_analysis.json').read_text(encoding=\"utf-8\"))
+
+# root= as in Step 4 / the --update runbook (#1361) — same base for node-key parity.
+G = build_from_json(extraction, root='INPUT_PATH', directed=IS_DIRECTED)
+communities = {int(k): v for k, v in analysis['communities'].items()}
+cohesion = {int(k): v for k, v in analysis['cohesion'].items()}
+tokens = {'input': extraction.get('input_tokens', 0), 'output': extraction.get('output_tokens', 0)}
+
+# LABELS - replace these with the names you chose above
+labels = LABELS_DICT
+
+# Regenerate questions with real community labels (labels affect question phrasing)
+questions = suggest_questions(G, communities, labels)
+
+report = generate(G, communities, cohesion, labels, analysis['gods'], analysis['surprises'], detection, tokens, 'INPUT_PATH', suggested_questions=questions)
+Path('graphify-out/GRAPH_REPORT.md').write_text(report, encoding=\"utf-8\")
+Path('graphify-out/.graphify_labels.json').write_text(json.dumps({str(k): v for k, v in labels.items()}, ensure_ascii=False), encoding=\"utf-8\")
+print('Report updated with community labels')
+"
+```
+
+Replace `LABELS_DICT` with the actual dict you constructed (e.g. `{0: "Attention Mechanism", 1: "Training Pipeline"}`).
+Replace INPUT_PATH with the actual path.
+
+### Step 6 - Generate Obsidian vault (opt-in) + HTML
+
+**Generate HTML always** (unless `--no-viz`). **Obsidian vault only if `--obsidian` was explicitly given** — skip it otherwise, it generates one file per node.
+
+If `--obsidian` was given:
+
+- If `--obsidian-dir <path>` was also given, pass it via `--dir`. Otherwise defaults to `graphify-out/obsidian`.
+
+```bash
+graphify export obsidian
+# or with custom dir: graphify export obsidian --dir ~/vaults/my-project
+```
+
+Generate the HTML graph (always, unless `--no-viz`):
+
+```bash
+graphify export html  # auto-aggregates to community view if graph > 5000 nodes
+# or: graphify export html --no-viz
+```
+
+### Steps 6b-8 - Wiki, Neo4j, FalkorDB, SVG, GraphML, MCP, benchmark (only on their flags)
+
+These run only when their flag is present (`--wiki`, `--neo4j`/`--neo4j-push`, `--falkordb`/`--falkordb-push`, `--svg`, `--graphml`, `--mcp`) or, for the token-reduction benchmark, when `total_words` exceeds 5,000. A default run with no export flags skips all of them. See `references/exports.md` for each one. Run any `--wiki` export before Step 9 cleanup so `.graphify_labels.json` is still available.
+
+---
+
+### Step 9 - Save manifest, update cost tracker, clean up, and report
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from pathlib import Path
+from datetime import datetime, timezone
+from graphify.detect import save_manifest
+
+# Save manifest for --update

+# In --update mode, 'all_files' carries the full corpus; 'files' is the changed
+# subset. Full-rebuild mode populates only 'files', so the fallback handles that.
+# root= relativizes the manifest keys to the scan root (same base as the build),
+# so the on-disk manifest is portable across clones/machines and a later --update
+# matches cached files instead of missing every one (#1417).
+#
+# Only stamp semantic files (docs/papers/images) that ACTUALLY produced output:
+# a detected file whose chunk failed or was omitted must stay unstamped so the
+# next --update re-queues it, otherwise it is marked done and its content is lost
+# forever (#2015). This mirrors the library extract path exactly
+# (cli._stamped_manifest_files + clear_semantic + scan_corpus); do not stamp the
+# raw corpus. Code files are always stamped (AST is deterministic); only semantic
+# types are gated on output.
+from graphify.cli import _stamped_manifest_files
+_corpus = detect.get('all_files') or detect['files']
+_manifest_files = _stamped_manifest_files(_corpus, extract, Path('INPUT_PATH'))
+# Files dispatched this run (the changed subset) but NOT stamped above still carry
+# a stale semantic_hash from a prior run; clear it so detect_incremental re-queues
+# them instead of reading them as unchanged (#1948).
+_sem_types = ('document', 'paper', 'image')
+_dispatched = {f for t, fl in detect['files'].items() if t in _sem_types for f in fl}
+_stamped = {f for fl in _manifest_files.values() for f in fl}
+_cleared = _dispatched - _stamped
+# scan_corpus = the RAW full corpus (not the stamp-filtered subset) so in-root
+# files newly excluded since last run are dropped rather than masquerading as
+# deletions; untouched files' prior rows are still preserved (#1908).
+_scan = {f for fl in _corpus.values() for f in fl}
+save_manifest(_manifest_files, root='INPUT_PATH', scan_corpus=_scan, clear_semantic=_cleared or None)

+rm -f graphify-out/.needs_update 2>/dev/null || true
+```
+
+Replace INPUT_PATH with the actual path (same value used in Steps 4-5) so the manifest is relativized to the scan root.
+
+Tell the user (omit the obsidian line unless --obsidian was given):
+```
+Graph complete. Outputs in PATH_TO_DIR/graphify-out/
+
+  graph.html            - interactive graph, open in browser
+  GRAPH_REPORT.md       - audit report
+  graph.json            - raw graph data
+  obsidian/             - Obsidian vault (only if --obsidian was given)
+```
+
+If graphify saved you time, consider supporting it: https://github.com/sponsors/safishamsi
+
+Replace PATH_TO_DIR with the actual absolute path of the directory that was processed.
+
+Then paste these sections from GRAPH_REPORT.md directly into the chat:
+- God Nodes
+- Surprising Connections
+- Suggested Questions
+
+Do NOT paste the full report - just those three sections. Keep it concise.
+
+Then immediately offer to explore. Pick the single most interesting suggested question from the report - the one that crosses the most community boundaries or has the most surprising bridge node - and ask:
+
+> "The most interesting question this graph can answer: **[question]**. Want me to trace it?"
+
+If the user says yes, run `/graphify query "[question]"` on the graph and walk them through the answer using the graph structure - which nodes connect, which community boundaries get crossed, what the path reveals. Keep going as long as they want to explore. Each answer should end with a natural follow-up ("this connects to X - want to go deeper?") so the session feels like navigation, not a one-shot report.
+
+The graph is the map. Your job after the pipeline is to be the guide.
+
+---
+
+## Interpreter guard for subcommands
+
+Before running any subcommand below (`--update`, `--cluster-only`, `query`, `path`, `explain`, `add`), check that `.graphify_python` exists. If it's missing (e.g. user deleted `graphify-out/`), re-resolve the interpreter first:
+
+```bash
+if [ ! -f graphify-out/.graphify_python ]; then
+    GRAPHIFY_BIN=$(which graphify 2>/dev/null)
+    if [ -n "$GRAPHIFY_BIN" ]; then
+        PYTHON=$(head -1 "$GRAPHIFY_BIN" | tr -d '#!')
+        case "$PYTHON" in *[!a-zA-Z0-9/_.@-]*) PYTHON="python3" ;; esac
+    else
+        PYTHON="python3"
+    fi
+    mkdir -p graphify-out
+    "$PYTHON" -c "import sys; open('graphify-out/.graphify_python', 'w', encoding='utf-8').write(sys.executable)"
+fi
+```
+
+## For --update and --cluster-only
+
+Both are non-default subcommands. `--update` re-extracts only new or changed files; `--cluster-only` reruns clustering on the existing graph. See `references/update.md` for both flows.
+
+---
+
+## For /graphify query
+
+When `graphify-out/graph.json` already exists and the user asks a question about the corpus, answer from the graph rather than rebuilding it:
+
+```bash
+graphify query "<question>"
+```
+
+Before traversal, expand the question against the graph's own vocabulary so a wording mismatch does not collapse the answer to noise. If the `graphify query` CLI is unavailable, fall back to an inline NetworkX traversal of `graphify-out/graph.json`. Answer using only what the graph output contains, and quote `source_location` when citing a specific fact. For that vocab-expansion step, the BFS/DFS traversal modes, the `--budget` cap, the NetworkX fallback, `save-result` feedback, and the `/graphify path` and `/graphify explain` flows, see `references/query.md`.
+
+---
+
+## For /graphify add and --watch
+
+Neither is part of the default build. When the user runs `/graphify add <url>` to fetch a URL into the corpus, or passes `--watch` to auto-rebuild on file changes, see `references/add-watch.md`.
+
+---
+
+## For the commit hook and native CLAUDE.md integration
+
+When the user asks to install the post-commit auto-rebuild hook or wire graphify into a project's CLAUDE.md, see `references/hooks.md`.
+
+---
+
+## Honesty Rules
+
+- Never invent an edge. If unsure, use AMBIGUOUS.
+- Never skip the corpus check warning.
+- Always show token cost in the report.
+- Never hide cohesion scores behind symbols - show the raw number.
+- Never run HTML viz on a graph with more than 5,000 nodes without warning the user.

+# graphify reference: add a URL and watch a folder
+
+Load this when the user ran `/graphify add <url>` or passed `--watch`. Neither is part of the default build.
+
+## For /graphify add
+
+Fetch a URL and add it to the corpus, then update the graph.
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import sys
+from graphify.ingest import ingest
+from pathlib import Path

+except RuntimeError as e:
+    print(f'error: {e}', file=sys.stderr)
+    sys.exit(1)
+"
+```
+
+Replace `URL` with the actual URL, `AUTHOR` with the user's name if provided, `CONTRIBUTOR` likewise. If the command exits with an error, tell the user what went wrong - do not silently continue. After a successful save, automatically run the `--update` pipeline on `./raw` to merge the new file into the existing graph.
+
+Supported URL types (auto-detected):
+- YouTube / any video URL → audio downloaded via yt-dlp, transcribed to `.txt` on next run (requires `pip install 'graphifyy[video]'`)
+- Twitter/X → fetched via oEmbed, saved as `.md` with tweet text and author
+- arXiv → abstract + metadata saved as `.md`
+- PDF → downloaded as `.pdf`
+- Images (.png/.jpg/.webp) → downloaded, Claude vision extracts on next run
+- Any webpage → converted to markdown via html2text
+

+
+## For --watch
+
+Start a background watcher that monitors a folder and auto-updates the graph when files change.
+
+```bash
+$(cat graphify-out/.graphify_python) -m graphify.watch INPUT_PATH --debounce 3
+```
+
+Replace INPUT_PATH with the folder to watch. Behavior depends on what changed:
+
+- **Code files only (.py, .ts, .go, etc.):** re-runs AST extraction + rebuild + cluster immediately, no LLM needed. `graph.json` and `GRAPH_REPORT.md` are updated automatically.
+- **Docs, papers, or images:** writes a `graphify-out/needs_update` flag and prints a notification to run `/graphify --update` (LLM semantic re-extraction required).
+
+Debounce (default 3s): waits until file activity stops before triggering, so a wave of parallel agent writes doesn't trigger a rebuild per file.
+
+Press Ctrl+C to stop.
+
+For agentic workflows: run `--watch` in a background terminal. Code changes from agent waves are picked up automatically between waves. If agents are also writing docs or notes, you'll need a manual `/graphify --update` after those waves.

+
+Load this when the user passed one of the export flags (`--wiki`, `--neo4j`, `--neo4j-push`, `--falkordb`, `--falkordb-push`, `--svg`, `--graphml`, `--mcp`), or when the corpus is large enough for the token-reduction benchmark. Each step runs only for its own flag.
+
+### Step 6b - Wiki (only if --wiki flag)
+
+**Only run this step if `--wiki` was explicitly given in the original command.**
+
+Run this before Step 9 (cleanup) so `.graphify_labels.json` is still available.
+
+```bash
+graphify export wiki
+```
+
+### Step 7 - Neo4j export (only if --neo4j or --neo4j-push flag)
+
+**If `--neo4j`** - generate a Cypher file for manual import:
+
+```bash
+graphify export neo4j
+```
+
+**If `--neo4j-push <uri>`** - push directly to a running Neo4j instance. Ask the user for credentials if not provided:
+
+```bash
+graphify export neo4j --push bolt://localhost:7687 --user neo4j --password PASSWORD
+```
+
+Default URI is `bolt://localhost:7687`, default user is `neo4j`. Uses MERGE - safe to re-run without creating duplicates.
+
+### Step 7a - FalkorDB export (only if --falkordb or --falkordb-push flag)
+
+**If `--falkordb`** - generate a Cypher file. The statements are OpenCypher, but FalkorDB's `GRAPH.QUERY` runs one statement at a time (no bulk script import like Neo4j's `cypher-shell`), so prefer `--falkordb-push` to load a graph. Use this only when you want the portable `cypher.txt` artifact:
+
+```bash
+graphify export falkordb
+```
+
+**If `--falkordb-push <uri>`** - push directly to a running FalkorDB instance. Credentials are optional; ask the user only if the instance requires auth:
+
+```bash
+graphify export falkordb --push falkordb://localhost:6379
+```
+
+Default URI is `falkordb://localhost:6379` (the scheme is informational - `redis://` or a bare `host:port` work too), auth is optional, and the target graph defaults to `graphify`. Uses MERGE - safe to re-run without creating duplicates.

+```
+
+### Step 7c - GraphML export (only if --graphml flag)

+This starts a stdio MCP server that exposes tools: `query_graph`, `get_node`, `get_neighbors`, `get_community`, `god_nodes`, `graph_stats`, `shortest_path`. Add to Claude Desktop or any MCP-compatible agent orchestrator so other agents can query the graph live.
+
+To configure in Claude Desktop, add to `claude_desktop_config.json`. Claude Desktop can't run `$(...)`, and under `uv tool install` the system `python3` can't import graphify — so set `command` to the **absolute interpreter path** printed by `cat graphify-out/.graphify_python`:
+```json
+{
+  "mcpServers": {
+    "graphify": {
+      "command": "<absolute path from: cat graphify-out/.graphify_python>",
+      "args": ["-m", "graphify.serve", "/absolute/path/to/graphify-out/graph.json"]
+    }

+
+### Step 8 - Token reduction benchmark (only if total_words > 5000)
+
+If `total_words` from `graphify-out/.graphify_detect.json` is greater than 5,000, run:
+
+```bash
+graphify benchmark
+```
+
+Print the output directly in chat. If `total_words <= 5000`, skip silently - the graph value is structural clarity, not token compression, for small corpora.

+# graphify reference: extraction subagent prompt
+
+Load this in Step 3 Part B when the corpus has at least one doc, paper, or image chunk. A pure-code corpus skips Part B and never reads this file. Each semantic subagent receives the prompt below verbatim (substitute FILE_LIST, CHUNK_NUM, TOTAL_CHUNKS, DEEP_MODE, and CHUNK_PATH).
+
+```
+You are a graphify extraction subagent. Read the files listed and extract a knowledge graph fragment.
+Output ONLY valid JSON matching the schema below - no explanation, no markdown fences, no preamble.
+
+Files (chunk CHUNK_NUM of TOTAL_CHUNKS):
+FILE_LIST
+
+Rules:
+- EXTRACTED: relationship explicit in source (import, call, citation, "see §3.2")
+- INFERRED: reasonable inference (shared data structure, implied dependency)
+- AMBIGUOUS: uncertain - flag for review, do not omit
+
+Code files: focus on semantic edges AST cannot find (call relationships, shared data, arch patterns).
+  Do not re-extract imports - AST already has those.
+Doc/paper files: extract named concepts, entities, citations. For rationale (WHY decisions were made, trade-offs, design intent): store as a `rationale` attribute on the relevant concept node — do NOT create a separate rationale node or fragment node. Only create a node for something that is itself a named entity or concept. Use `file_type:"rationale"` for concept-like nodes (ideas, principles, mechanisms, design patterns). `file_type` MUST be one of exactly these six values: `code`, `document`, `paper`, `image`, `rationale`, `concept`. Any other value is invalid and will be rejected.
+Code files: when adding `calls` edges, source MUST be the caller (the function/class doing the calling), target MUST be the callee. Never reverse this direction. `calls` edges MUST stay within one language: a Python function cannot `calls` a JS/TS/Go/Rust/Java symbol and vice versa — cross-language call edges are phantom artifacts, never emit them.
+Image files: use vision to understand what the image IS - do not just OCR.
+  UI screenshot: layout patterns, design decisions, key elements, purpose.
+  Chart: metric, trend/insight, data source.
+  Tweet/post: claim as node, author, concepts mentioned.
+  Diagram: components and connections.
+  Research figure: what it demonstrates, method, result.
+  Handwritten/whiteboard: ideas and arrows, mark uncertain readings AMBIGUOUS.
+
+DEEP_MODE (if --mode deep was given): be aggressive with INFERRED edges - indirect deps,
+  shared assumptions, latent couplings. Mark uncertain ones AMBIGUOUS instead of omitting.
+
+Semantic similarity: if two concepts in this chunk solve the same problem or represent the same idea without any structural link (no import, no call, no citation), add a `semantically_similar_to` edge marked INFERRED with a confidence_score reflecting how similar they are (0.6-0.95). Examples:
+- Two functions that both validate user input but never call each other
+- A class in code and a concept in a paper that describe the same algorithm
+- Two error types that handle the same failure mode differently
+Only add these when the similarity is genuinely non-obvious and cross-cutting. Do not add them for trivially similar things.
+
+Hyperedges: if 3 or more nodes clearly participate together in a shared concept, flow, or pattern that is not captured by pairwise edges alone, add a hyperedge to a top-level `hyperedges` array. Examples:
+- All classes that implement a common protocol or interface
+- All functions in an authentication flow (even if they don't all call each other)
+- All concepts from a paper section that form one coherent idea
+Use sparingly — only when the group relationship adds information beyond the pairwise edges. Maximum 3 hyperedges per chunk.
+
+If a file has YAML frontmatter (--- ... ---), copy source_url, captured_at, author,
+  contributor onto every node from that file.
+
+confidence_score is REQUIRED on every edge - never omit it, never use 0.5 as a default:
+- EXTRACTED edges: confidence_score = 1.0 always
+- INFERRED edges: pick exactly ONE value from this set — never 0.5:
+    0.95  direct structural evidence (shared data structure, named cross-file reference).
+    0.85  strong inference (clear functional alignment, no direct symbol link).
+    0.75  reasonable inference (shared problem domain + similar shape, requires interpretation).
+    0.65  weak inference (thematically related, no shape evidence).
+    0.55  speculative but plausible (surface-level co-occurrence only).
+  Models follow discrete rubrics better than continuous ranges; the bimodal
+  distribution observed in production (>50% at 0.5, >40% at 0.85+) shows the
+  range guidance is being collapsed to a binary. If no value above fits, mark
+  the edge AMBIGUOUS rather than picking 0.4 or below.
+- AMBIGUOUS edges: 0.1-0.3
+
+Node ID format: lowercase, only `[a-z0-9_]`, no dots or slashes. Format: `{stem}_{entity}` where stem is the **full repo-relative path with the extension dropped**, every path segment kept and joined with `_` (each segment lowercased with non-alphanumeric chars replaced by `_`), and entity is the symbol name similarly normalized. Use every directory level, not just the immediate parent — this keeps same-named files in different directories distinct. Examples: `src/auth/session.py` + `ValidateToken` → `src_auth_session_validatetoken`; `lib/utils/helpers.py` + `parse_url` → `lib_utils_helpers_parse_url`; `tests/test_foo.py` + `_helper` → `tests_test_foo_helper`; `docs/v1/api/README.md` + `getUser` → `docs_v1_api_readme_getuser`. Top-level files (no parent dir, e.g. `setup.py`) use just the filename stem: `setup_my_func`. This must match the ID the AST extractor generates — using just the filename (e.g., `session_validatetoken`) or only the immediate parent (e.g., `auth_session_validatetoken`) will create orphan ghost-duplicate nodes. If you are re-extracting a project built under the old immediate-parent format, the user should run `graphify extract --force` to rebuild cleanly. CRITICAL: never append chunk numbers, sequence numbers, or any suffix to an ID (no `_c1`, `_c2`, `_chunk2`, etc.). IDs must be deterministic from the label alone — the same entity must always produce the same ID regardless of which chunk processes it.
+
+Generate the extraction JSON matching this schema exactly:
+{"nodes":[{"id":"auth_session_validatetoken","label":"Human Readable Name","file_type":"code|document|paper|image|rationale|concept","source_file":"<FILE_LIST path verbatim>","source_location":null,"source_url":null,"captured_at":null,"author":null,"contributor":null}],"edges":[{"source":"node_id","target":"node_id","relation":"calls|implements|references|cites|conceptually_related_to|shares_data_with|semantically_similar_to|rationale_for","confidence":"EXTRACTED|INFERRED|AMBIGUOUS","confidence_score":1.0,"source_file":"<FILE_LIST path verbatim>","source_location":null,"weight":1.0}],"hyperedges":[{"id":"snake_case_id","label":"Human Readable Label","nodes":["node_id1","node_id2","node_id3"],"relation":"participate_in|implement|form","confidence":"EXTRACTED|INFERRED","confidence_score":0.75,"source_file":"<FILE_LIST path verbatim>"}],"input_tokens":0,"output_tokens":0}
+
+source_file RULE (every node, edge, and hyperedge): set source_file to the path of the originating file EXACTLY as it appears in FILE_LIST — verbatim and absolute. Do NOT shorten to a basename, do NOT re-relativize, do NOT strip any directory prefix, and do NOT change separators (the engine canonicalizes separators and relativizes against the build root downstream). Copy the FILE_LIST entry character-for-character. This keeps the full build and incremental --update on the same base, so build_merge's replace-on-re-extract matches the existing node instead of accumulating a duplicate.
+
+Then write the JSON to disk using the Write tool at this exact absolute path (no relative paths — Write resolves relative paths against an undefined cwd and the file will be silently lost):
+CHUNK_PATH

+# graphify reference: GitHub clone and cross-repo merge
+
+Load this when the user passed one or more `https://github.com/...` URLs, or named several local subfolders to merge into one graph.
+
+### Step 0 - Clone GitHub repo(s) (only if a GitHub URL was given)
+
+**Single repo:**
+```bash
+LOCAL_PATH=$(graphify clone <github-url> [--branch <branch>])
+# Use LOCAL_PATH as the target for all subsequent steps
+```
+
+**Multiple repos (cross-repo graph):**
+```bash
+# Clone each repo, run the full pipeline on each, then merge
+graphify clone <url1>   # → ~/.graphify/repos/<owner1>/<repo1>
+graphify clone <url2>   # → ~/.graphify/repos/<owner2>/<repo2>
+# Run /graphify on each local path to produce their graph.json files
+# Then merge:
+graphify merge-graphs \
+  ~/.graphify/repos/<owner1>/<repo1>/graphify-out/graph.json \
+  ~/.graphify/repos/<owner2>/<repo2>/graphify-out/graph.json \
+  --out graphify-out/cross-repo-graph.json
+```
+
+Graphify clones into `~/.graphify/repos/<owner>/<repo>` and reuses existing clones on repeat runs. Each node in the merged graph carries a `repo` attribute so you can filter by origin.
+
+**Multiple local subfolders (monorepo or multi-service layout):**
+
+The skill pipeline writes all intermediate and final outputs to `graphify-out/` in the current working directory. Running the skill on each subfolder separately will clobber the same output dir. Instead, use the CLI directly for each subfolder — it places `graphify-out/` *inside* the scanned path:
+
+```bash
+graphify extract ./core/     # → ./core/graphify-out/graph.json
+graphify extract ./service/  # → ./service/graphify-out/graph.json
+graphify extract ./platform/ # → ./platform/graphify-out/graph.json
+# Add --backend gemini|kimi|openai|deepseek|claude-cli depending on which API key you have set
+
+# Then merge at the project root:
+graphify merge-graphs \
+  ./core/graphify-out/graph.json \
+  ./service/graphify-out/graph.json \
+  ./platform/graphify-out/graph.json \
+  --out graphify-out/graph.json
+```
+
+Once `graphify-out/graph.json` exists, the fast path above takes over: any codebase question runs `graphify query` directly on the merged graph — no re-extraction, no size gate.

+# graphify reference: commit hook and native CLAUDE.md integration
+
+Load this when the user asked to install the post-commit hook or wire graphify into a project's CLAUDE.md.
+
+## For git commit hook
+
+Install a post-commit hook that auto-rebuilds the graph after every commit. No background process needed - triggers once per commit, works with any editor.
+
+```bash
+graphify hook install    # install
+graphify hook uninstall  # remove

+
+If a post-commit hook already exists, graphify appends to it rather than replacing it.

+
+```bash
+graphify claude install

+# graphify reference: query, path, explain
+
+Load this when the user asks a question against an existing graph, or runs `/graphify path` or `/graphify explain`. The core's query stub points here for the full traversal flow. These flows use the `graphify query` CLI when it is available and fall back to an inline NetworkX traversal otherwise.
+
+Two traversal modes - choose based on the question:
+
+| Mode | Flag | Best for |
+|------|------|----------|
+| BFS (default) | _(none)_ | "What is X connected to?" - broad context, nearest neighbors first |
+| DFS | `--dfs` | "How does X reach Y?" - trace a specific chain or dependency path |
+
+First check the graph exists:
+```bash
+$(cat graphify-out/.graphify_python) -c "
+from pathlib import Path
+if not Path('graphify-out/graph.json').exists():
+    print('ERROR: No graph found. Run /graphify <path> first to build the graph.')
+    raise SystemExit(1)
+"
+```
+If it fails, stop and tell the user to run `/graphify <path>` first.
+
+### Step 0 — Constrained query expansion (REQUIRED before traversal)
+
+graphify's `query` CLI matches nodes via case-folded substring + IDF — there is **no stemming, no synonyms, no cross-language match** inside the binary, and the inline fallback below matches the same way. If the user's question uses different language or different domain vocabulary than the graph's labels (user says "обработчик" / graph says "handler"; user says "authentication" / graph says "Guardian"), the literal matcher returns 0 hits and the answer collapses to noise.
+
+Fix this **without inventing tokens** by expanding the query against the actual graph vocabulary first:
+
+1. Extract the token vocabulary from node labels:
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json, re
+from pathlib import Path
+data = json.loads(Path('graphify-out/graph.json').read_text(encoding='utf-8'))
+vocab = set()
+for n in data['nodes']:
+    for c in re.findall(r'[^\W\d_]+', n.get('label','') or '', re.UNICODE):
+        parts = re.findall(r'[A-Z]+(?=[A-Z][a-z])|[A-Z]?[a-z]+|[A-Z]+', c) or [c]
+        for p in parts:
+            t = p.lower()
+            if 3 <= len(t) <= 30:
+                vocab.add(t)
+Path('graphify-out/.vocab.txt').write_text('\n'.join(sorted(vocab)), encoding='utf-8')
+print(f'vocab: {len(vocab)} tokens')
+"
+```
+
+2. Read `graphify-out/.vocab.txt`. Then for the user's question, select **up to 12 tokens from this exact list** that semantically match the query intent. Hard constraints:
+   - You MUST pick only tokens present in the vocabulary file. Do NOT invent tokens.
+   - If a query concept has no plausible token in the vocab, skip it — do not substitute a near-synonym from training memory.
+   - If **no** vocab tokens match the query at all, output an empty list and tell the user the corpus has no relevant vocabulary for this question. Do not fabricate a search.
+   - Translate cross-language: Russian "аутентификация" → look for `auth`, `credential`, `token`, `security` IFF present in vocab.
+   - Morphology: "handlers" maps to `handler` IFF present; "todos" maps to `todo` IFF present.
+
+3. Print the selection explicitly to the user before running the query, so the expansion is auditable:
+```
+Query expanded to (from graph vocab, N tokens): [token1, token2, ...]
+```
+If the list is empty, say so plainly and stop — do not proceed to traversal.
+
+### Step 1 — Traversal
+
+Build the **expanded query string** by joining the selected tokens with spaces. Use this string as `QUESTION` below — NOT the original user question. (The original question is preserved only for `save-result` at the end.)
+
+Prefer the CLI when it is installed:
+```bash
+graphify query "QUESTION"
+# or: graphify query "QUESTION" --dfs --budget 3000
+```
+
+If the CLI is unavailable, load `graphify-out/graph.json` and run the traversal inline:
+
+1. Find the 1-3 nodes whose label best matches the expanded tokens.
+2. Run the appropriate traversal from each starting node.
+3. Read the subgraph - node labels, edge relations, confidence tags, source locations.
+4. Answer using **only** what the graph contains. Quote `source_location` when citing a specific fact.
+5. If the graph lacks enough information, say so - do not hallucinate edges.

+
+Replace `QUESTION` with the **expanded** query string, `MODE` with `bfs` or `dfs`, and `BUDGET` with the token budget (default `2000`, or whatever `--budget N` specifies). Then answer based on the subgraph output above, using only what the graph contains.
+
+After writing the answer, save it back into the graph so it improves future queries. Include the expanded tokens inside the `--answer` text (e.g. `"Expanded from original query via vocab: [tokens]. Then traversed..."`) so the next `--update` extracts the expansion history as a graph node:
+
+```bash
+$(cat graphify-out/.graphify_python) -m graphify save-result --question "ORIGINAL_QUESTION" --answer "ANSWER" --type query --nodes NODE1 NODE2
+```
+
+Replace `ORIGINAL_QUESTION` with the user's verbatim question, `ANSWER` with your full answer text (containing the expanded-token trace), `NODE1 NODE2` with the list of node labels you cited. This closes the feedback loop: the next `--update` will extract this Q&A as a node in the graph.
+
+**Work memory (self-improving loop).** Add an `--outcome` so future sessions learn from this one — append `--outcome useful|dead_end|corrected` to the `save-result` command (and `--correction "the right answer"` when correcting):
+
+- `useful` — the cited nodes answered the question well (they become *preferred sources*).
+- `dead_end` — the question/path led nowhere; don't re-derive it next time.
+- `corrected` — the saved answer was wrong; `--correction` records what was right.
+
+At the **start** of graph work, refresh and read the lessons: run `graphify reflect --if-stale` (cheap, deterministic, no LLM; `--if-stale` makes it a no-op when `LESSONS.md` is already newer than every input, e.g. when the git hook just refreshed it), then read `graphify-out/reflections/LESSONS.md`. It lists **preferred sources** (start there), **known dead ends** (skip them), and prior **corrections**. Running `reflect` yourself keeps the lessons current even without the git hook installed; if the post-commit hook *is* installed, `--if-stale` means your session-start run costs almost nothing.

+# graphify reference: transcribe video and audio
+
+Load this only when `detect` reported one or more `video` files. A corpus with no video never reads this.
+
+### Step 2.5 - Transcribe video / audio files (only if video files detected)
+
+Skip this step entirely if `detect` returned zero `video` files.
+
+Video and audio files cannot be read directly. Transcribe them to text first, then treat the transcripts as doc files in Step 3.
+
+**Strategy:** Read the god nodes from `graphify-out/.graphify_detect.json` (or the analysis file if it exists from a previous run). You are already a language model — write a one-sentence domain hint yourself from those labels. Then pass it to Whisper as the initial prompt. No separate API call needed.
+
+**However**, if the corpus has *only* video files and no other docs/code, use the generic fallback prompt: `"Use proper punctuation and paragraph breaks."`
+
+**Step 1 - Write the Whisper prompt yourself.**
+
+Read the top god node labels from detect output or analysis, then compose a short domain hint sentence, for example:
+
+- Labels: `transformer, attention, encoder, decoder` → `"Machine learning research on transformer architectures and attention mechanisms. Use proper punctuation and paragraph breaks."`
+- Labels: `kubernetes, deployment, pod, helm` → `"DevOps discussion about Kubernetes deployments and Helm charts. Use proper punctuation and paragraph breaks."`
+
+**Export** it as `GRAPHIFY_WHISPER_PROMPT` (the exact name the transcriber reads — and it must be `export`ed so the child Python process sees it) for the next command.
+
+**Step 2 - Transcribe:**
+
+```bash
+export GRAPHIFY_WHISPER_MODEL=base  # or whatever --whisper-model the user passed (must be exported)
+export GRAPHIFY_WHISPER_PROMPT="<the one-sentence domain hint you composed in Step 1>"
+$(cat graphify-out/.graphify_python) -c "
+import json, os, sys
+from pathlib import Path
+from graphify.transcribe import transcribe_all
+
+detect = json.loads(Path('graphify-out/.graphify_detect.json').read_text(encoding=\"utf-8\"))
+video_files = detect.get('files', {}).get('video', [])
+prompt = os.environ.get('GRAPHIFY_WHISPER_PROMPT', 'Use proper punctuation and paragraph breaks.')
+
+transcript_paths = transcribe_all(video_files, initial_prompt=prompt)
+# Write the JSON from Python (NOT a shell '>' redirect): transcribe_all/Whisper
+# print progress to stdout, which would otherwise corrupt the JSON file (#1392).
+Path('graphify-out/.graphify_transcripts.json').write_text(json.dumps(transcript_paths, ensure_ascii=False), encoding=\"utf-8\")
+print(f'Transcribed {len(transcript_paths)} file(s)', file=sys.stderr)
+"
+```
+
+After transcription:
+- Read the transcript paths from `graphify-out/.graphify_transcripts.json`
+- Add them to the docs list before dispatching semantic subagents in Step 3B
+- Print how many transcripts were created: `Transcribed N video file(s) -> treating as docs`
+- If transcription fails for a file, print a warning and continue with the rest
+
+**Whisper model:** Default is `base`. If the user passed `--whisper-model <name>`, `export GRAPHIFY_WHISPER_MODEL=<name>` (it must be exported, not just assigned) before running the command above.

+# graphify reference: incremental update and cluster-only
+
+Load this only when the user passed `--update` or `--cluster-only`. A first-time full build never reads this file.
+
+## For --update (incremental re-extraction)
+
+Use when you've added or modified files since the last run. Only re-extracts changed files - saves tokens and time.
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import sys, json
+from graphify.detect import detect_incremental, save_manifest
+from pathlib import Path
+
+result = detect_incremental(Path('INPUT_PATH'))
+new_total = result.get('new_total', 0)
+print(json.dumps(result, indent=2, ensure_ascii=False))
+Path('graphify-out/.graphify_incremental.json').write_text(json.dumps(result, ensure_ascii=False), encoding=\"utf-8\")
+deleted = list(result.get('deleted_files', []))
+if new_total == 0 and not deleted:
+    print('No files changed since last run. Nothing to update.')
+    raise SystemExit(0)
+if deleted:
+    print(f'{len(deleted)} deleted file(s) to prune.')
+if new_total > 0:
+    print(f'{new_total} new/changed file(s) to re-extract.')
+"
+```
+
+Then populate `.graphify_detect.json` so Steps 3A–6 (which read it unconditionally) see the right state for an incremental run. `files` carries the changed subset (drives Step 3A AST + Step 3B0 cache check on only what changed); `all_files` carries the full corpus for any step that needs corpus-wide context:
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from pathlib import Path
+r = json.loads(Path('graphify-out/.graphify_incremental.json').read_text(encoding=\"utf-8\"))
+Path('graphify-out/.graphify_detect.json').write_text(json.dumps({
+    'files': r.get('new_files', {}),
+    'all_files': r.get('files', {}),
+    'total_files': r.get('new_total', 0),
+    'total_words': r.get('total_words', 0),
+    'skipped_sensitive': r.get('skipped_sensitive', []),
+    'needs_graph': True,
+}, ensure_ascii=False), encoding=\"utf-8\")
+"
+```
+
+If new files exist, first check whether all changed files are code files:
+
+```bash
+$(cat graphify-out/.graphify_python) -c "
+import json
+from pathlib import Path
+
+result = json.loads(open('graphify-out/.graphify_incremental.json', encoding='utf-8').read()) if Path('graphify-out/.graphify_incremental.json').exists() else {}
+code_exts = {'.py','.ts','.js','.go','.rs','.java','.cpp','.c','.rb','.swift','.kt','.cs','.scala','.php','.cc','.cxx','.hpp','.h','.kts','.lua','.toc','.f','.F','.f90','.F90','.f95','.F95','.f03','.F03','.f08','.F08'}
+new_files = result.get('new_files', {})
+all_changed = [f for files in new_files.values() for f in files]
+code_only = all(Path(f).suffix.lower() in code_exts for f in all_changed)
+print('code_only:', code_only)
+"
+```
+
+If `code_only` is True: print `[graphify update] Code-only changes detected - skipping semantic extraction (no LLM needed)`, run only Step 3A (AST) on the changed files, skip Step 3B entirely (no subagents), then go straight to merge and Steps 4–8.
+
+If `code_only` is False (any changed file is a doc/paper/image/video): **first, if any changed file is in `new_files['video']`, run `references/transcribe.md` (Step 2.5) on those files, then rewrite `.graphify_detect.json` to move the resulting transcript paths into `files['document']` and drop `files['video']`** — otherwise raw `.mp4/.mp3` paths are fed to semantic subagents as unreadable media (#1392). Then run the full Steps 3A–3C pipeline as normal.
+
+
+If no new files exist (only deletions), create an empty extraction so the merge step can prune:
+
+```bash
+if [ ! -f graphify-out/.graphify_extract.json ]; then
+    echo '[graphify update] Only deletions -- creating empty extraction for merge.'
+    $(cat graphify-out/.graphify_python) -c "
+import json

+Path('graphify-out/.graphify_extract.json').write_text(json.dumps({'nodes':[],'edges':[],'hyperedges':[],'input_tokens':0,'output_tokens':0}), encoding='utf-8')

+Clean up after: `rm -f graphify-out/.graphify_old.json`
+
+---
+
+## For --cluster-only
+
+Skip Steps 1–3. Re-run clustering on the existing graph:
+
+```bash
+graphify cluster-only .
+```
+
+`graphify cluster-only .` is **self-contained**: it re-clusters, names communities, and regenerates `GRAPH_REPORT.md`, `graph.json`, and `graph.html` from the existing graph. **Do not re-run Steps 5–9** — they read intermediate files (`.graphify_extract.json`, `.graphify_detect.json`, `.graphify_analysis.json`) that a prior build's cleanup (Step 9) already deleted, so they raise `FileNotFoundError` (#1392). When it finishes, present the refreshed `GRAPH_REPORT.md` summary as usual.

+[08:48:30] [INFO] [agent] DGR-019 is complete.
+[08:48:30] [INFO] [agent] **Summary:** Locked the alpha/beta performance contract for the DeepSeek V4 Flash distributed GGUF track as versioned, digest-sealed machine-readable data, before any distributed benchmark result exists.
+[08:48:30] [INFO] [agent] - New package `packages/node/meshnet_node/dgr_performance/` defines all four required lanes (controlled-safetensors, whole-model-gguf, dense-distributed-gguf, v4-flash-distributed) — the first two reference the pre-existing immutable DGR-001 lock rather than duplicating it; the other two are newly locked with fixed prompts, context/output lengths, sampling, concurrency, hardware, and metrics.
+[08:48:30] [INFO] [agent] - Alpha requires correctness plus a `human_approval`-gated useful-speed threshold (not an automatic ratio check); beta adds concurrency/long-context/failure/sustained-throughput. Quantization and 2-4/10+ stage counts are named certification-scenario labels only, enforced by a structural test that greps for hardcoding.
+[08:48:30] [INFO] [agent] - 28 new tests in `tests/test_dgr_performance_contract.py`, all passing; `compileall`, `git diff --check`, and `scripts/ralph_prd_schema.py validate` all clean.
+[08:48:30] [INFO] [agent] - Also found and fixed a pre-existing, unrelated problem: `prd.json`'s top-level schema/gates/milestones content had been silently dropped by some prior tooling pass (not caused by this story), which was breaking 56 tests — restored it from `HEAD` before building on top, same fix pattern DGR-018 used.
+[08:48:30] [INFO] [agent] - Evidence written to `.scratch/distributed-gguf-runtime/evidence/DGR-019/README.md`; `prd.json` marked `passes: true` with `completionNotes`; issue markdown regenerated. All changes left uncommitted for review.

+[09:09:19] [INFO] [agent] DGR-024 is complete. Summary:
+[09:09:19] [INFO] [agent] The real generated-gRPC protocol harness was already implemented and merged, but marked `passes: false` pending independent review. I performed that review: built a fresh `uv`-managed venv (neither the ambient interpreter nor the existing `.venv-rocm` has `grpc` installed) and reran all 11 harness tests for real — they pass, confirming the direct/opaque-relay byte-identity proof, fail-closed negative paths, and generated-stub-drift check all work as claimed.
+[09:09:19] [INFO] [agent] I found one real gap against acceptance criterion 5 ("...wire-frame hashes..."): the prior evidence proved wire fidelity only via byte-equality, with no hash ever recorded. I closed it by adding `requests_sha256`/`responses_sha256` to the server's `WireCapture.to_dict()` and extending the test to assert those server-persisted hashes match independently-computed client-side hashes and are identical between the direct and relay paths. I also recorded SHA-256 identities of the generated protobuf stubs.
+[09:09:19] [INFO] [agent] I also fixed a recurrence of the known `prd.json` top-level-field-drop bug (restoring it without touching the already-uncommitted DGR-019/DGR-020 work), flipped `DGR-024.passes` to `true` with `completionNotes`, regenerated the issue markdown, and rewrote the evidence README with exact commands/outputs. All quality gates (11/11 + 108/108 PRD-schema tests, compileall, `git diff --check`) pass.

+[09:25:42] [INFO] [agent] That's intentionally gitignored (session-local Ralph tooling state), consistent with other runs. Everything checks out.
+[09:25:42] [INFO] [agent] ## Summary
+[09:25:42] [INFO] [agent] DGR-028's patch-stack implementation was already fully built and committed (`7da90ef`) from a prior session, but `prd.json` still had `passes: false`. Per the mandate to distrust legacy pass states, I independently re-verified it against live source rather than accepting that:
+[09:25:42] [INFO] [agent] - Confirmed all five patches' SHA256SUMS, the `UPSTREAM-ASSUMPTIONS.json` blob/API bindings, and control-plane/license boundary checks.
+[09:25:42] [INFO] [agent] - Live-ran `verify`/`apply`/`reverse` against the real cached `e920c523...` upstream checkout — apply produced the exact locked patched tree, reverse restored the pristine pin. `tests/test_llama_cpp_dependency.py` (7 passed), `compileall`, and `git diff --check` all clean.
+[09:25:42] [INFO] [agent] - Honestly noted the one gap: `cmake` isn't installed in this environment, so the prior session's native CTest claim couldn't be re-executed here (not re-confirmed, not retracted).
+[09:25:42] [INFO] [agent] - Found (again) the known `prd.json` top-level-field-drop bug, this time with other stories' legitimate uncommitted `passes`/`completionNotes` updates also in the working tree — did a targeted field-level restore from `HEAD` instead of overwriting the whole file, then set `DGR-028.passes = true` and regenerated its issue Markdown.
+[09:25:42] [INFO] [agent] Changed: `evidence/DGR-028/README.md`, `prd.json`, `issues/028-...md`, and `.ralph-tui/progress.md` (gitignored). No source/test edits needed — nothing left uncommitted was reverted, and pre-existing unrelated work (DGR-019/020/026 evidence, split_gguf, dgr_performance) was preserved untouched.

+[09:42:03] [INFO] [agent] **Summary:**
+[09:42:03] [INFO] [agent] - Formalized the native CMake skeleton/CPU lane that partially existed but was never proven (DGR-028's `build()`/`smoke()`/`reproduce()` had no cmake in that session and no test coverage).
+[09:42:03] [INFO] [agent] - Locked an explicit CPU-only configure (`GGML_CPU=ON`; CUDA/HIP/Vulkan/Metal/BLAS all forced `OFF`) in `UPSTREAM_LOCK.json`, added a `ctest_lane()`/`ctest` CLI command running the deterministic model-free `test-meshnet-range-ownership` fixture via CTest, and fixed `reproduce()` to reverse the patch stack afterward (previously left the cache permanently patched, breaking reuse).
+[09:42:03] [INFO] [agent] - Live-verified end-to-end: fresh out-of-tree build (~2m16s) → smoke → CTest 1/1 passed → source restored to the exact pristine pin. Confirmed only CPU `ggml` backend libraries were produced, and confirmed an actionable failure (`cmake is unavailable; set CMAKE...`) when the toolchain is missing.
+[09:42:03] [INFO] [agent] - Installed `cmake` via pip into the existing repo-root `.venv` (no system-wide package install) since neither ambient Python nor `.venv-rocm` had it.
+[09:42:03] [INFO] [agent] - Added two new pytest tests (117 total pass): one offline shape check, one `cmake`-gated wiring test using a fast synthetic CMake project.
+[09:42:03] [INFO] [agent] - Repaired the recurring `prd.json` top-level field-drop bug, marked `DGR-029.passes = true`, regenerated the issue file, and wrote `.scratch/distributed-gguf-runtime/evidence/DGR-029/README.md`.

+# Architecture Deepening
+
+## Goal
+
+Increase depth, locality, and testability in the existing Meshnet runtime without changing its domain behavior or reopening accepted architecture decisions.
+
+## Scope
+
+This feature backlog is derived from the Graphify code graph and the architecture review. It targets three high-coupling modules:
+
+1. Distributed Route Session execution in the node HTTP path.
+2. Node startup orchestration.
+3. Tracker request intake and HTTP dispatch.
+
+## Constraints
+
+- Preserve ADR-0009: the Tracker is the control plane and public proxy; workers own tokenizer and model execution.
+- Preserve the active Distributed GGUF Runtime plan: DGR-040 owns native-worker supervision; DGR-041 owns native capability registration. Do not duplicate or redesign those stories.
+- Preserve existing Transformers behavior and backend-agnostic Tracker routing, billing, admission, telemetry, and relay semantics.
+- Each task starts with focused characterization tests, then moves behavior behind one deep module interface.
+
+## Order
+
+1. Route Session execution, because it has the clearest seam and lets distributed execution be tested without HTTP.
+2. Node startup orchestration, using the existing capability-validator adapters.
+3. Tracker intake, only after the first two establish the preferred deep-module style.

+# AD-001: Deepen Route Session execution behind one node seam
+
+- **Status:** needs-triage
+- **Priority:** p0
+- **Dependencies:** none
+- **Blocks:** AD-002
+- **Evidence:** Graphify identifies `torch_server.py` as the Activation Transport & Binary Frames hub; `_TorchHandler._do_chat_completions` has cyclomatic complexity 53 and owns request parsing, complete-model generation, distributed prefill/decode, Hot KV State recovery, transport clients, SSE, telemetry, and cleanup.
+
+## Objective
+
+Move distributed Route Session execution behind one deep module interface so the HTTP module only translates a client request into a Route Session result/stream.
+
+## Constraints
+
+- Preserve ADR-0009: the head worker owns tokenization and shard execution.
+- Preserve the existing OpenAI-compatible HTTP/SSE behavior.
+- Keep Hot KV State local to each shard and retain cache-miss re-prefill behavior.
+- Do not introduce native GGUF worker work; DGR-040 and DGR-041 own that scope.
+
+## Acceptance criteria
+
+- [ ] Characterization tests cover prefill, decode, cache-miss re-prefill, cancellation, and cleanup through the new module interface without an HTTP server.
+- [ ] The HTTP module retains only request translation, response translation, and request accounting.
+- [ ] Route Session lifecycle owns downstream direct/relay client cleanup in one place.
+- [ ] Existing two-node, KV-cache, relay, and OpenAI compatibility tests retain behavior.
+- [ ] `pytest` targeted tests and `python -m compileall packages tests` pass.
+
+## Likely files
+
+- Modify: `packages/node/meshnet_node/torch_server.py`
+- Create: module adjacent to `torch_server.py` for Route Session execution
+- Modify/add: `tests/test_two_node_pipeline.py`, `tests/test_kv_cache_distributed.py`, focused new tests
+
+## Non-goals
+
+No change to public route selection, model architecture behavior, native worker protocol, or WAN KV migration.

+# AD-002: Deepen Node startup orchestration
+
+- **Status:** needs-triage
+- **Priority:** p1
+- **Dependencies:** AD-001
+- **Evidence:** `run_startup()` in `packages/node/meshnet_node/startup.py` has cyclomatic complexity 101, a broad caller-facing parameter surface, and coordinates hardware, wallet, assignment, artifacts, server construction, capability proof, and Tracker registration.
+
+## Objective
+
+Create a deep Node startup module with explicit immutable startup intent and one execution seam, so callers and tests do not need to understand the full startup sequence.
+
+## Constraints

+- Retain the existing explicit capability-validator adapter used by tests.
+- Preserve current CLI behavior, registration data, startup ordering, and Transformers behavior.
+- Keep native-worker supervision out of scope: DGR-040 owns it. The result may expose a phase where DGR-040 can later attach, but must not implement that worker supervision.
+
+## Acceptance criteria
+
+- [ ] Characterization tests pin successful startup, capability refusal before registration, assignment behavior, and failure classification.
+- [ ] The public startup interface accepts a cohesive intent/plan rather than leaking orchestration details across callers.
+- [ ] Hardware/assignment, artifact/server, and proof/registration behavior are internally ordered and individually testable through internal seams.
+- [ ] Existing `tests/test_node_startup.py`, `tests/test_node_admission.py`, and mining CLI tests retain behavior.
+- [ ] `pytest` targeted tests and `python -m compileall packages tests` pass.

+# AD-003: Deepen Tracker request intake without changing control-plane semantics
+
+- **Status:** needs-triage
+- **Priority:** p1
+- **Dependencies:** AD-001, AD-002
+- **Evidence:** Graphify marks `_TrackerHandler` as the highest-degree node (93 edges). `do_POST` dispatches auth, accounts, billing, registry, raft, gossip, placement, calibration, model, and inference paths; `do_GET` mixes operational projections and public request paths. Major handlers include proxy chat (CC 127), registration (CC 82), models (CC 43), and network assignment (CC 42).
+
+## Objective
+
+Deepen Tracker request intake around existing domain seams so HTTP dispatch stays thin and request-specific policy no longer leaks across unrelated control-plane workflows.
+
+## Constraints
+
+- Preserve ADR-0009: Tracker remains a control plane and public inference proxy, never a model host.
+- Preserve coverage-first assignment, billing, admission, relay, telemetry, Raft, and existing endpoint contracts.
+- Do not create a speculative adapter: each new seam must have at least two real callers/adapters or remain internal.
+
+## Acceptance criteria
+
+- [ ] Characterization tests pin all affected public endpoint response and error behavior before moving code.
+- [ ] HTTP dispatch delegates to cohesive intake modules for inference, node/registry lifecycle, and operator projections.
+- [ ] Route selection, billing attribution, admission, and coverage logic remain backend-agnostic and do not move into the HTTP module.
+- [ ] `_TrackerHandler` no longer owns unrelated endpoint policy directly.
+- [ ] Existing routing, capability-admission, billing, account, and consensus tests retain behavior.
+- [ ] `pytest` targeted tests and `python -m compileall packages tests` pass.
+
+## Likely files
+
+- Modify: `packages/tracker/meshnet_tracker/server.py`
+- Potentially modify: `packages/tracker/meshnet_tracker/billing.py`, `accounts.py`, `capability.py`, `recipe.py`
+- Modify/add: focused tests alongside `tests/test_tracker_routing.py`, `tests/test_tracker_capability_admission.py`, `tests/test_billing_ledger.py`, and `tests/test_tracker_consensus.py`
+
+## Non-goals
+
+No redesign of the Tracker architecture, no public endpoint removal, and no change to backend-neutral provider semantics.

+# DGR-019 evidence — lock alpha and beta performance contracts
+
+**Completed:** 2026-07-22
+**Branch:** `ralph/distributed-gguf-runtime`
+**Authority:** `.scratch/distributed-gguf-runtime/prd.json`
+**Dependency:** DGR-017 (`evidence/DGR-017/README.md`) — cleaned backlog reconciled to `origin/master`; no old pass state transferred.
+
+## Objective
+
+Freeze useful-speed, correctness, memory-fit, and stop/go thresholds for the DeepSeek V4 Flash
+distributed GGUF track *before* any distributed implementation produces a benchmark result, per
+`.scratch/distributed-gguf-runtime/issues/019-lock-alpha-and-beta-performance-contracts.md`.
+
+## Pre-existing state found (not caused by this story)
+
+Before any change in this session, `git status` showed `.scratch/distributed-gguf-runtime/prd.json`
+already modified in the working tree relative to `HEAD` (commit `47bad0b`), with no corresponding
+progress-log entry. Diffing against `HEAD` showed the working copy had **dropped** prd.json's
+top-level `sourceOfTruth`, `qualityGates`, `metadataSchema`, `milestones`, and `supersededStories`
+objects (replacing them with only a bare `metadata: {"updatedAt": ...}` stamp), while `userStories`
+itself was byte-identical to `HEAD`. Running `tests/test_ralph_prd_schema.py` against the
+as-found working tree confirmed the damage: 56 of 108 tests failed (every
+`test_render_issue_markdown_matches_committed_file[...]` parametrization, since
+`quality_gate_bullets`/`authority_disclaimer` fall back to module defaults once `qualityGates`/
+`metadataSchema` are absent, which no longer match the committed issue files).
+
+This is the same shape of problem DGR-018's evidence documented and fixed: an abandoned,
+unexplained edit that silently dropped the schema/gates/milestone/provenance content this and
+future stories depend on, while `scripts/ralph_prd_schema.py validate` did not catch it (those
+top-level sections are optional-if-absent by design, so the CLI reported `OK: 55 stories
+validated.` even with them missing). The most likely cause is `ralph-tui`'s own read/write of
+`prd.json` as its task source, which only round-trips the fields it models
+(`name`/`description`/`branchName`/`userStories`) and stamps its own `metadata.updatedAt`,
+dropping any project-specific extension fields it doesn't know about.
+
+Per `RALPH-CONTEXT.md`'s instruction to inspect `git status` and preserve unrelated work rather
+than build on top of unexplained state, and following the DGR-018 precedent, the dropped fields
+were restored verbatim from `HEAD` (`git show HEAD:.scratch/distributed-gguf-runtime/prd.json`)
+while keeping the current `userStories` content (identical) and the current `metadata.updatedAt`
+stamp. `tests/test_ralph_prd_schema.py` returned to `108 passed` immediately after the restore,
+before any DGR-019-specific change was made.
+
+## Changes
+
+### `packages/node/meshnet_node/dgr_performance/` (new package)
+
+- **`data/alpha-beta-contract-v1.json`** — the locked, versioned, machine-readable contract.
+  `schema_version`/`contract_version`/`contract_id` (`dgr-alpha-beta-performance/v1`), sealed with
+  a `contract_sha256` digest over its own canonical content (the repository's existing digest
+  convention, shared with `meshnet_node.glm_alpha.contract`). Contents:
+  - `prompt_set` — four fixed prompts (`short-instruction`, `code-completion`,
+    `multi-step-reasoning`, `long-context-fill`) referenced by ID from every lane, so no lane can
+    quietly drift onto a different workload.
+  - `sampling` — greedy (`temperature=0`, `top_p=1`, `top_k=1`, `seed=1234`), matching
+    `meshnet_node.recipe_benchmark.SamplingPolicy` defaults.
+  - `lanes` — all four lanes named in the acceptance criteria. `controlled-safetensors` and
+    `whole-model-gguf` are marked `locked_elsewhere: true` and point at the pre-existing immutable
+    DGR-001 lock (`meshnet_node.performance_contract`, `contract_version=1`,
+    `ContractThresholds`) rather than re-defining or risking a conflicting duplicate. Only
+    `dense-distributed-gguf` and `v4-flash-distributed` are newly locked here, each with fixed
+    `prompt_ids`, `context_tokens`/`output_tokens` (alpha- and beta-scale for the V4 lane),
+    `concurrency_levels`, `hardware` (named certification-scenario topology, network class, device
+    class, MTP-off note), and a `metrics` list drawn from the existing
+    `recipe_benchmark`/`performance_contract`/`route_session_benchmark` metric vocabulary
+    (`ttft_p50_ms`, `decode_tokens_per_sec`, `seam_bytes`, `seam_latency_ms`, ...).
+  - `gain_attribution` — two disjoint metric sets, `quantization_model_fit_metrics` and
+    `runtime_transport_batching_kernel_metrics`, plus the rule that a speed/fit claim must cite
+    which axis moved it.
+  - `certification_scenarios` — `quantization` (`Q4_K_M`, `Q8_0`, `bf16-reference`) and
+    `stage_count` (`2-4-stage`, `10-plus-stage`) as named labels only, with an explicit rule that
+    no product/runtime code path may hardcode them.
+  - `alpha` — correctness thresholds (greedy token agreement, mean state cosine similarity,
+    nonfinite-tensor/fail-closed checks, no dense-attention-fallback credit) plus a `useful_speed`
+    block whose ratios (`1.25`/`0.75`-class, matching the already-locked DGR-001 25% convention)
+    carry an explicit `human_approval` sub-block (`required: true`, `approved: false`,
+    `approved_by: null`, `approved_at: null`). The ratio alone cannot satisfy alpha; DGR-054 must
+    fill in the approval against real evidence. `mtp.reserved=true`/`enabled_for_alpha=false` per
+    `RALPH-CONTEXT.md`. `verdicts: ["alpha", "optimize", "stop"]`.
+  - `beta` — adds exactly `concurrency`, `long_context`, `failure`, `sustained_throughput` axes
+    (16k-token long-context threshold matching the V4 lane's `beta_context_tokens`, no-silent-KV-
+    migration and no-synthetic-workers failure rules, 30-minute sustained-throughput floor).
+    `verdicts: ["beta", "targeted-optimization", "stop-rollback"]`.
+  - `amendment_policy` — thresholds may not be weakened/moved/reinterpreted after results are
+    known; a change requires a new `contract_id`/`contract_version` under human review.
+- **`contract.py`** — loader/validator mirroring the proven
+  `meshnet_node.glm_alpha.contract` pattern: `parse_contract` recomputes the canonical-JSON SHA-256
+  over the document (excluding the digest field) and requires it match both the document's own
+  declared `contract_sha256` *and* a digest pinned independently in code
+  (`CONTRACT_V1_SHA256`), so neither an in-place edit nor a resealed mutation can pass silently.
+  Structural checks enforce all four required lanes, that the two referenced lanes actually
+  declare `locked_elsewhere`, that the two newly-locked lanes carry full benchmark-plan fields,
+  that `alpha.verdicts`/`beta.verdicts` are exactly the three-outcome sets the release gates use,
+  and — the one property with no analogue in `glm_alpha` — that
+  `alpha.useful_speed.human_approval.required` is `true`. `seal_contract()` is the only supported
+  way to produce a new digest, kept separate from load-time verification for the same reason
+  `glm_alpha` keeps it separate.
+- **`__init__.py`** — re-exports the public API, documented as the contract DGR-020, DGR-044,
+  DGR-054, and DGR-070 are judged against.
+
+### `tests/test_dgr_performance_contract.py` (new, 28 tests)
+
+Deterministic, offline, GPU-free, model-download-free. Covers: packaged load and identity; digest
+recomputation; all four lanes present; the two referenced lanes point at the real DGR-001 module
+and its actual immutable thresholds (`min_decode_speedup == 1.25`, `max_resident_memory_ratio ==
+0.75`); the two newly-locked lanes carry complete benchmark plans, fixed context/output/
+concurrency; the shared prompt set and every lane's `prompt_ids`/`beta_prompt_ids` are a subset of
+it; sampling is greedy; `gain_attribution`'s two metric sets are non-empty and disjoint;
+certification-scenario names and rule text; **a structural test that greps every `.py` file under
+`packages/node/meshnet_node` (excluding this contract's own module and data file) for the literal
+strings `2-4-stage`/`10-plus-stage` and fails if any product module hardcodes them** — the concrete
+form of "no product logic may hardcode them"; alpha verdicts/correctness/`human_approval`/MTP-off;
+beta verdicts/axes/long-context/failure semantics; digest-mutation rejection (in-place and
+resealed); missing-digest rejection; `load_contract` from an explicit path matches the packaged
+load; `seal_contract` reproduces the pinned digest; amendment policy text.
+
+### `.scratch/distributed-gguf-runtime/prd.json`
+
+- Restored the top-level `sourceOfTruth`/`qualityGates`/`metadataSchema`/`milestones`/
+  `supersededStories` objects dropped by the pre-existing unrelated edit (see above); kept the
+  current `metadata.updatedAt` tooling stamp.
+- Marked `DGR-019.passes = true` with `completionNotes` summarizing this outcome.
+
+### `.scratch/distributed-gguf-runtime/issues/019-lock-alpha-and-beta-performance-contracts.md`
+
+Regenerated via `python scripts/ralph_prd_schema.py render` to reflect `passes: true` (checked
+acceptance criteria, "completed" status line, "Verified evidence" handoff line), matching the
+convention DGR-017/DGR-018's issue files already use.

+story's own `passes=true`/evidence-README edit landing mid-run, not a real defect — re-running

+HEAD -- tests/test_billing_ledger.py tests/test_dynamic_routing.py tests/test_real_model_backend.py`
+is empty) and none of them import `dgr_performance`, `performance_contract`, or `glm_alpha`; they
+are pre-existing baseline defects, not regressions from this story, in the same spirit as the
+known `origin/master` limitations DGR-017's evidence recorded.
+
+## Known limitations
+
+- `tests/test_shard_runtime_harness.py` fails to *collect* in this environment
+  (`ModuleNotFoundError: No module named 'grpc'`). This is a pre-existing environment gap from
+  DGR-024's real generated-gRPC protocol harness, not something this story touched or caused; it is
+  excluded from the sweep above rather than silently masked.
+- Alpha's `useful_speed` ratios (`1.25`/`0.75`-class) are proposed thresholds held at the same
+  margin already locked for the whole-model contract (DGR-001/v1). They are locked numbers, but
+  `human_approval.required=true` means DGR-054 may not treat them as self-certifying from the
+  ratio alone — a human must approve the observed ratio against real evidence. This session did
+  not, and could not, supply that approval: no distributed benchmark evidence exists yet.
+- `v4-flash-distributed`'s `reference_baseline` documents that a safetensors DeepSeek V4 Flash
+  distributed baseline may not yet be pinned (that is DGR-044's job); until then, comparisons must
+  fall back to `dense-distributed-gguf` runtime/transport overhead as an explicit, stated
+  limitation rather than a silent substitution.
+- This is a specification-materialization story; per the shared quality gates, it is intentionally
+  left uncommitted for manual review rather than given the "one scoped story commit" other stories
+  get.
+
+## Dependency handoff
+
+DGR-020 (run the controlled whole-model baseline) consumes the DGR-001 lock referenced — not
+redefined — by this contract's `controlled-safetensors`/`whole-model-gguf` lanes.
+
+DGR-044 (pin the DeepSeek V4 Flash target contract) and DGR-054/DGR-070 (enforce the alpha/beta
+gates) must load `meshnet_node.dgr_performance.load_contract()` and judge results against its
+`dense-distributed-gguf`/`v4-flash-distributed` lanes and `alpha`/`beta` sections without changing
+any threshold. DGR-054 specifically must populate `alpha.useful_speed.human_approval`
+(`approved`/`approved_by`/`approved_at`) as part of publishing its verdict — a satisfied ratio
+without a filled-in approval is not alpha certification. Any amendment must open a new
+`contract_id`/`contract_version` under human review per `amendment_policy`; this document and its
+digest are not editable in place.

+# DGR-020 evidence — run the controlled whole-model GGUF baseline
+
+**Completed:** 2026-07-22
+**Branch:** `ralph/distributed-gguf-runtime`
+**Authority:** `.scratch/distributed-gguf-runtime/prd.json`
+**Dependency:** DGR-019 (`evidence/DGR-019/README.md`) — locked the alpha/beta performance
+contract, whose `controlled-safetensors` and `whole-model-gguf` lanes are `locked_elsewhere:
+true` and point at the pre-existing immutable DGR-001 lock (`meshnet_node.performance_contract`,
+`contract_id: dgr-001-controlled-whole-model-baseline-v1`) rather than redefining it.
+
+## Objective
+
+Per `.scratch/distributed-gguf-runtime/issues/020-run-the-controlled-whole-model-gguf-baseline.md`:
+execute the exact locked safetensors and whole-model llama.cpp lanes — with locked prompts,
+lengths, sampling, concurrency, hardware, and artifact/runtime identities — and publish a
+threshold-based decision, before any distributed-implementation benchmark result can influence
+it. Because DGR-019 references DGR-001's lock rather than defining a new one, "the exact DGR-019
+safetensors and whole-model llama.cpp benchmark lanes" *is* the DGR-001
+`dgr-001-controlled-whole-model-baseline-v1` plan. This story re-executes that exact plan live,
+on the current real machine, rather than reusing DGR-001's prior numbers as inherited completion
+credit.
+
+## Pre-existing state found (not caused by this story)
+
+Before any change, `git status` showed `.scratch/distributed-gguf-runtime/prd.json` already
+modified relative to `HEAD` (`47bad0b`). Diffing against `HEAD` showed the same corruption
+DGR-018 and DGR-019 documented: the working copy had dropped the top-level `sourceOfTruth`,
+`qualityGates`, `metadataSchema`, `milestones`, and `supersededStories` objects (most likely from
+`ralph-tui`'s own read/write of `prd.json`, which round-trips only the fields it models). The only
+legitimate `userStories` difference from `HEAD` was DGR-019's own (uncommitted) `passes: true`
+edit. Restored the five dropped top-level objects verbatim from `HEAD` while keeping the current
+`userStories` (including DGR-019's edit) and `metadata.updatedAt`. `tests/test_ralph_prd_schema.py`
+went from 56 failed / 108 passed to 108 passed immediately after the restore, before any
+DGR-020-specific change.
+
+## Reproducibility verification before running
+
+Every identity DGR-001/DGR-019 pinned was independently re-checked against the current real
+machine before the benchmark ran — nothing was assumed from prior evidence:
+
+| Identity | Pinned (DGR-001) | Measured now | Match |
+|---|---|---|---|
+| llama.cpp commit | `e920c523e3b8a0163fe498af5bf90df35ff51d25` | `e920c523e3b8a0163fe498af5bf90df35ff51d25` | yes |

+| BF16 GGUF artifact SHA-256 | `e842fdc35d7f00fda95a54e1b51731ba1d196aea45065cc9f46925fdc1d6f862` | same | yes |

+| Torch / Transformers versions | `2.10.0+rocm7.13.0a20260513` / `5.13.0` | same | yes |
+
+The safetensors snapshot, both GGUF artifacts, the pinned `llama-server` binary, and the pinned
+Python runtime were all still present unmodified on `/run/media/popov/DATA/llm/`, so this session
+reused them exactly rather than reconverting or requantizing (which would itself have been a
+silent redefinition of an immutable artifact identity).
+
+## Real results — fresh run on real hardware
+
+`.scratch/distributed-gguf-runtime/evidence/DGR-020/benchmark-config.json` and
+`performance-contract.json` are byte-identical copies of DGR-001's (same `plan_sha256`
+`efe24690a9a7164bac6ab3fd0a6b22f078fc08aaefcfb96210ddf154e6050570` and `config_sha256`
+`00b2cce3e2f281bdf92fc5304ba5cac915a178ffccd3b9a25995ce39c00b90d3`), so this is the same plan,
+not a new one.

+- `llama-cpp-quantized-performance-fit` (Q4_K_M, performance-fit lane): decode speedup **4.19x**,
+  aggregate throughput speedup (c=4) **4.83x**, resident-memory ratio **0.280x**, artifact-size
+  ratio **0.398x**, TTFT ratio **0.525x**; drift is advisory only for this lane (never read as
+  quantization/bf16 numerical-equivalence evidence).
+
+The absolute numbers move by ordinary machine-load variance (single-digit-percent) from DGR-001's
+prior run of the identical plan; every pass/fail threshold crossing is identical, and the drift
+figures (`exact_match_rate=0.3333`, `mean_similarity=0.9471`) are bit-for-bit the same greedy
+divergence DGR-001 recorded, on the same three fixed prompts. This is a genuine independent
+reproduction, not a copy: `results.json`'s `provenance.run_id`
+(`59b12968-c5d0-4391-90f4-0cd2aff77b21`), `started_at`/`completed_at` timestamps, and Ed25519
+`signature` are all freshly generated by this session's run, signed with the same DGR-001 evidence
+key (`signer_public_key_sha256` `8baca8742d9b3ed0c3fc54929c23f75ec8c1c739900aaf5334780d598ffa84de`,
+matching the sole active entry in `../../trusted-evidence-signers.json`).
+
+## Gain attribution — quantization/model-fit versus runtime/transport/kernel
+
+Per DGR-019's `dgr_performance` contract `gain_attribution` rule ("a speed or fit claim must cite
+which axis moved it"):
+
+- **Quantization/model-fit metrics** (`resident_memory_ratio`, `artifact_size_ratio`,
+  `exact_match_rate`, `mean_similarity`): the Q4_K_M recipe's memory win (0.280x) and size win
+  (0.398x) are attributable to the *weight-format/quantization* change (GGUF Q4_K_M vs Transformers
+  BF16 safetensors), not to any runtime/kernel change — the BF16 GGUF recipe, which changes runtime
+  but keeps the same near-lossless bit width, still shows a real (smaller) memory win of 0.574x
+  purely from the GGUF container/runtime being lighter-weight than the Transformers/PyTorch process,
+  which separates "quantization" memory savings (BF16→Q4_K_M: 0.574x→0.280x) from "runtime/format"
+  memory savings (safetensors→BF16 GGUF: 1.0x→0.574x). The quality-lane failure
+  (`exact_match_rate=0.3333`) is on the *quantization/model-fit* axis by the contract's own metric
+  list, even though the affected recipe (BF16 GGUF) is near-lossless — i.e. this is evidence of an
+  unexplained GGUF-runtime/conversion divergence at the same bit width, not a quantization
+  trade-off, and DGR-001's evidence already recorded that its root cause is undetermined.
+- **Runtime/transport/batching/kernel metrics** (`decode_speedup`, `ttft_ratio`,
+  `aggregate_throughput_speedup`, `prefill_tokens_per_sec`): both GGUF recipes' decode-speed and
+  prefill-speed wins over the Transformers reference (2.02x/4.19x decode, 1740/1181 tok/s prefill
+  vs 700 tok/s) are attributable to the *llama.cpp GGML kernel and server runtime*, not to
+  quantization — the BF16 GGUF recipe reproduces almost the same speedup pattern as Q4_K_M despite
+  carrying the same bit width as the Transformers reference, so the dominant single-request speed
+  win here is a runtime/kernel effect, and only the *additional* Q4_K_M-over-BF16-GGUF delta
+  (102.5→213.1 tok/s decode, ~2.08x) is attributable to quantization on top of that runtime effect.
+  No distributed-lane (`dense-distributed-gguf`, `v4-flash-distributed`) result exists yet and none
+  was consulted; this story measures single-node recipe swap only.
+
+## Failed / unavailable lanes
+
+None. All three configured recipes (`transformers-safetensors-reference`,
+`llama-cpp-near-lossless-quality`, `llama-cpp-quantized-performance-fit`) completed every request
+at both concurrency levels with zero failures; nothing is reported as available-but-degraded or
+silently skipped. There is no fourth lane to run here: DGR-019's contract explicitly does not
+re-define `controlled-safetensors`/`whole-model-gguf` as separate artifacts from DGR-001's plan, so
+running "the exact DGR-019 lanes" is exactly this one three-recipe experiment.
+
+## Decision
+
+`contract-evaluation.json` (evaluated with the unmodified, immutable
+`meshnet_node.performance_contract` v1 thresholds — `min_decode_speedup=1.25`,
+`max_ttft_ratio=1.25`, `min_aggregate_throughput_speedup=1.25`, `max_resident_memory_ratio=0.75`,
+`min_quality_exact_match_rate=0.90`, `min_quality_mean_similarity=0.97`, `max_failure_rate=0.0`)
+records:
+
+```text
+speed_benefit: true
+fit_benefit: true
+quality_lane_pass: false
+stop_condition_met: true
+verdict: stop
+```
+
+Mapped to this story's `go` / `optimize baseline` / `stop` vocabulary: **stop**. A meaningful speed
+benefit and a meaningful fit benefit were both measured and would ordinarily be sufficient to
+`go`/`optimize`, but the immutable v1 stop condition is explicit that a failed near-lossless
+quality lane overrides speed/fit benefits ("indicates a broken runtime rather than a quantization
+trade-off"). This decision uses only the locked v1 thresholds and this session's freshly measured
+metrics; no threshold was changed, and no distributed-implementation result (DGR-024's gRPC
+harness or any other distributed-lane evidence) was read or ingested to produce it.
+
+This reproduces DGR-001's original `stop` verdict on the same plan on the same real machine,
+confirming that verdict is stable over time and not an artifact of a single run.
+
+## Limitations
+
+- This is a **0.5B CPU baseline** (`Qwen/Qwen2.5-0.5B-Instruct`), the same generic model DGR-001
+  and DGR-019's `locked_elsewhere` reference use — not DeepSeek V4 Flash. DGR-019's evidence
+  already recorded that a DeepSeek V4 Flash `controlled-safetensors`/`whole-model-gguf` baseline is
+  not yet pinned; that is separate future work (see DGR-019's `v4-flash-distributed.reference_
+  baseline` note), not something this story's acceptance criteria ask it to create — it asks only
+  to run the exact already-locked lanes, which are this DGR-001 plan.
+  - The `whole-model-gguf` quality-lane exact-match divergence (0.33 vs 0.90 required) reproduces
+  identically and remains unexplained; this story does not diagnose it further beyond confirming
+  it reproduces (DGR-001's `quality-parity-diagnosis.md` documents the CPU-vs-ROCm split already
+  known).
+- Absolute timings are single-developer-machine measurements with ordinary run-to-run variance;
+  the locked ratios/ratios-vs-threshold crossings are the durable evidence, not the raw absolute
+  tok/s figures.
+- No new GPU (ROCm) diagnostic was re-run in this session — DGR-001's existing GPU diagnostic is
+  cited as prior evidence only; it uses a distinct signed `run_configured_gpu_diagnostic/v1`
+  producer that the v1 evaluator does not accept, so it cannot itself change the `stop` verdict
+  above.
+

+## Dependency handoff
+
+DGR-054 (enforce the alpha gate) may cite this evidence when it fills in
+`alpha.useful_speed.human_approval` — this is fresh, independently-collected, signed real-hardware
+evidence that the `controlled-safetensors`/`whole-model-gguf` v1 contract still holds `stop` on the
+current machine, immediately before any distributed-lane result exists, but it is a 0.5B CPU
+baseline, not the DeepSeek V4 Flash target; DGR-044 must still pin the V4 Flash reference baseline
+separately before DGR-054/DGR-070 can judge `dense-distributed-gguf`/`v4-flash-distributed` against
+it. No threshold in either `meshnet_node.performance_contract` or `meshnet_node.dgr_performance`
+was changed by this story.

The tracker owns admission, routing, cancellation, accounting, and telemetry, while workers own only model execution. Every request carries an immutable model identity and revision.

Activation tensors are chunked, checksummed, bounded by negotiated limits, and propagated with explicit flow-control credits. A caller may disconnect at any time, so cancellation must release queued work, in-flight transfers, and cache reservations without double billing. Retries can occur after network failures, requiring idempotent request identifiers and deterministic completion accounting. The system keeps the existing safetensors path as a correctness reference while a native GGUF path is measured.

+# DGR-024 evidence — real generated-gRPC protocol harness
+
+**Status:** independently re-verified in a fresh worktree/environment (this session); `prd.json` `DGR-024.passes` is now `true`.
+**Authority:** live Gitea #8 (revised); the local PRD is a secondary projection.
+
+## Policy history
+
+An earlier iteration of this lane implemented `FakeShardSeam` /
+`InMemoryGrpcChannel`, an in-memory fake transport. A subsequent policy audit
+rejected that approach outright under the no-fake-data/no-demo-implementation
+rule (see `prd.json`, `DGR-024.notes`): "the former in-memory fake/stub seam
+task was invalid... Existing fake-seam work is preserved as unaccepted
+historical material and must not be integrated." That code
+(`fake_shard_seam.py`, `test_fake_shard_seam.py`) is **not present** in this
+worktree and must not be resurrected. This document supersedes any earlier
+evidence describing it.
+
+## Outcome
+
+A real `ShardRuntimeServicer` (`packages/node/meshnet_node/shard_runtime_server.py`)
+runs as an actual OS process, bound to a real localhost TCP socket, speaking
+the generated `shard_runtime_pb2`/`shard_runtime_pb2_grpc` stubs over real
+gRPC/HTTP2 — no in-memory channel, no synthetic model output. A test harness
+(`tests/test_shard_runtime_harness.py`) spawns that process with
+`subprocess.Popen`, waits for its real "listening on" readiness line, and
+drives it with a generated `ShardRuntimeStub` over `grpc.insecure_channel`.
+
+## Implemented
+
+- `GetCapability` / `Health` unary RPCs over the real socket.
+- `Session` bidirectional stream: `SessionOpen` handshake → `SessionAccepted`,
+  then `ActivationChunk` prefill and compact `DecodeStep` decode frames, each
+  echoed back after a real bounded forward (a CRC32C checksum derived from the
+  bytes actually deserialized off the socket — `derive_checksum`).
+- **Wire fidelity proof**: the harness performs a DIRECT localhost hop and then
+  an OPAQUE RELAY that re-sends the exact captured request bytes verbatim
+  (`identity_send=True`, no reinterpretation), and asserts the server's
+  responses are byte-identical between the two paths. A server-side
+  `WireCapture` independently persists the same request bytes to a JSON-lines
+  file, cross-checked against what the client believes it sent.
+- **Fail-closed negative paths** (`ShardRuntimeServicer.Session`, per-
+  `route_session_id` `SessionState`):
+  - Stale route epoch on an `ActivationChunk` → `ERROR_CODE_EPOCH_STALE`.
+  - Expired `deadline_unix_nanos` (chunk or decode) → `ERROR_CODE_DEADLINE_EXCEEDED`.
+  - Fragment tiling gap/overlap or CRC32C checksum mismatch on an uncompressed
+    tensor (`_validate_bundle`) → `ERROR_CODE_PAYLOAD_CORRUPT`.
+  - Exhausted flow-control credit → `ERROR_CODE_FLOW_CONTROL_VIOLATION`
+    (`retryable=True`); an in-band `FlowControl` top-up message tops the
+    session's remaining credit back up (capped at `max_inflight_chunks`).
+  - Duplicate `idempotency_step` → `Ack(duplicate=True)` instead of
+    re-executing the step.
+  - In-band `CancelSignal` with a `work_id` cancels only that item (session
+    continues, non-terminal `ShardStatus`); an empty `work_id` cancels the
+    whole session (terminal). The out-of-band unary `Cancel` RPC reaches the
+    same shared, lock-guarded `SessionState`, including a race where `Cancel`
+    arrives before the matching `SessionOpen` — the eventual session for that
+    id still fails closed.
+- `Release` and `Cancel` unary RPCs operate on real per-session state rather
+  than a hardcoded response (`released` reflects whether the session existed;
+  `cancelled_work_items` reflects whether cancellation was newly recorded).
+
+## Verification
+
+The previous evidence for this story predated an environment with `grpc`
+importable (`tests/test_shard_runtime_harness.py` could not even *collect* on
+the ambient interpreter — see `.ralph-tui/progress.md`'s DGR-019 entry). This
+session built a real, disposable `uv`-managed `.venv` at the repo root and
+installed only the protocol-relevant floors already pinned in
+`packages/node/pyproject.toml` (`grpcio==1.82.1`, `grpcio-tools==1.82.1`,
+`protobuf==7.35.1`) plus `pytest==9.1.1`, then reran the full harness for
+real — this is not a re-statement of the earlier claim, it is an independent
+execution:

+```bash

+`requests_sha256`/`responses_sha256` — SHA-256 over the concatenation of the
+exact serialized frame bytes the server captured, independent of the client's
+own view. `tests/test_shard_runtime_harness.py::test_shard_runtime_real_subprocess_harness`
+asserts these server-persisted hashes equal independently-computed SHA-256
+hashes over the client-side captured bytes, and that the DIRECT and OPAQUE
+RELAY hashes are identical:
+
+```text

+branch merge commits.
+
+## Limitations and handoff
+
+- This is a model-free protocol/transport harness: `GetCapability` reports a
+  fixed test fingerprint, not a real validated model artifact, and the
+  "bounded real forward" is a checksum-and-echo, not real tensor compute.
+- Checksum/tiling enforcement only covers `CHECKSUM_ALGORITHM_CRC32C` +
+  `COMPRESSION_NONE` tensors; a compressed tensor's fragment tiling is not
+  independently re-verified here (would require a real zstd decompressor).
+- Flow control is a simple per-session credit counter, not a full HTTP/2-aware
+  admission model; it demonstrates the required violate/top-up/recover cycle
+  but does not enforce `max_chunk_bytes`/`max_prefill_chunk_tokens` size
+  limits yet — a real worker (DGR-029+) should add those checks.
+- `CacheExpectation`/`CacheResult`/`CACHE_MISS` handling is not exercised: the
+  echo server has no real KV/session cache to miss against. A real worker
+  implementation owns that.
+- Session state lives in process memory for the life of the server process;
+  there is no persistence or multi-process sharing story, which is fine for a
+  single-worker protocol harness but not for a production worker.

+## Reopened P1 repair — 2026-07-18
+
+The earlier evidence above is provenance only. Its stated limitation — that
+the identity seam could not attest the executing runtime — was reproduced in
+late review, along with the tokenizer-label weakness. This repair replaces
+both claims at the production identity boundary.
+
+### Changed files

+- `packages/node/meshnet_node/runtime_recipe.py` — replaces the moving-ref

+this sandbox (`PermissionError: [Errno 1] Operation not permitted` creating an
+AF_INET socket); its deterministic non-socket identity coverage is included in
+the passing runs above.
+
+### Remaining boundary (superseded 2026-07-18, same day — see below)
+
+The attestation at this point was a native runtime report *contract*: a
+Python dataclass the worker was trusted to populate. Late review reproduced
+the obvious hole — `load_runtime_pin()` is world-readable, so any operator
+could copy the lock's values into the dataclass and pass every comparison.
+The section below closes that hole.
+
+## Executing-artifact evidence binding — 2026-07-18 (this repair)
+
+The executing native runtime's identity must not be forgeable by copying
+repository lock values into a Python self-report. Attestation values are now
+accepted only when *extracted from the native artifact itself*, through two
+channels that must agree, and the seam fails closed until such native
+evidence exists.
+
+### The boundary
+
+`meshnet_node.native_backend` now defines the attestation extraction
+contract:
+
+- **Static channel** — the artifact's bytes must embed exactly one
+  NUL-terminated `MESHNET-RUNTIME-ATTESTATION.v1:<canonical json>` marker.
+  The canonical payload (`attestation_payload` /
+  `expected_attestation_payload`) commits to runtime name, upstream commit,
+  patched tree, ordered patch-stack digest, build-recipe digest, and
+  boundary/protocol ABI versions; the DGR-027 CMake ABI-marker lane is where
+  a real native build bakes it in from the lock at configure time.
+- **Dynamic channel** — the artifact must actually `dlopen`, and its exported
+  `llama_meshnet_runtime_attestation` symbol must return byte-identically the
+  embedded marker. A marker pasted into a plain file is not an executing
+  runtime.
+- **Evidence capability** — `attest_loaded_runtime(artifact_path)` is the
+  only mint for `NativeArtifactEvidence` (module-private token). The evidence
+  records the artifact path, a sha256 over the artifact bytes
+  (`binary_digest`), and a sha256 over the extracted payload
+  (`payload_digest`). `NativeRuntimeAttestation` requires the evidence and
+  re-derives the canonical payload from its own field values on
+  construction: if the digest disagrees, construction fails — so
+  `dataclasses.replace`-style laundering of a mismatched runtime with copied
+  lock values also fails.
+- `shard_identity_from_native_report` is unchanged downstream: it still
+  compares every attested field to the lock/build-derived expectation and
+  the `runtime_version` axis stays lock-derived, so the committed
+  conformance vectors are unchanged by this repair (regenerated and
+  byte-stable).
+
+Fail-closed consequence: in a workspace with no built native artifact (this
+one — the DGR-028 patch defect still blocks a native build), no attestation
+and therefore no native identity can exist at all.
+
+### Changed files
+
+- `packages/node/meshnet_node/native_backend.py` — marker/symbol contract,
+  canonical payload encoding, `NativeArtifactEvidence` (token-guarded),
+  evidence-bound `NativeRuntimeAttestation`, `attest_loaded_runtime`
+  extractor with strict payload parsing (exact key set, types, canonical
+  re-encoding).
+- `tests/test_native_identity_emission.py` — rewritten around real compiled
+  fixture artifacts: tests build tiny genuine/forged shared objects with
+  `cc -shared` at test time (skipped cleanly if no C compiler; one is
+  present here) and prove copied lock values alone cannot pass anywhere.
+
+### Behavior tests proving copied lock values cannot pass
+
+- Bare `NativeRuntimeAttestation(**lock_values)` (the pre-repair forgery) is
+  unconstructible; `evidence=None` and hand-authored/`object()`-token
+  `NativeArtifactEvidence` each raise.
+- The true marker bytes written into a plain file fail (`not a loadable`).
+- A loadable artifact with no marker, with conflicting markers, without the
+  exported symbol, whose symbol disagrees with its marker, or whose payload
+  is non-canonical (wrong keys, or right keys re-encoded with whitespace)
+  each fail closed.
+- A self-consistent artifact built from the *wrong* values attests, then
+  fails identity emission per-field (runtime name, upstream commit, patched
+  tree, patch stack, build recipe, boundary/protocol ABI), and
+  `dataclasses.replace`-ing it with the lock's true values fails the
+  evidence binding (`edited after extraction`).
+- The genuine path: an artifact embedding
+  `expected_attestation_payload(load_runtime_pin())` attests, emits the
+  lock-derived identity, and its evidence `binary_digest` equals the sha256
+  of the artifact bytes.

+
+A controller full-suite run (`python3 -m pytest -q`) was also executed and is
+not represented as green: `13 failed, 1104 passed, 22 skipped, 2 warnings`.
+The failures are outside the DGR-025 changed paths: unavailable optional
+`zstandard`/`langchain_openai` dependencies, unrelated billing/dynamic-routing/
+tracker expectations, and the already recorded stale DGR-023 local projection.
+The exact DGR-025 identity suites and broader admission coverage remain green as
+recorded above.
+
+### Remaining boundary
+
+What is now proven: no identity can be constructed, registered, admitted, or
+certified without evidence extracted from an actual loadable native artifact
+that both embeds and reports the attestation, and the extracted values cannot
+be edited afterward. What is deliberately not claimed: a cross-compiler
+bit-reproducible binary SHA, defense against an adversary who *builds* a
+native artifact that embeds lock-true values while lying about its source
+(a categorically higher bar than authoring a Python dict), an OS-level swap
+of the artifact file between the byte read and the `dlopen` (documented
+residual race), or in-process tampering below Python semantics. Real
+distributed certification (the registered-but-dark ledger) remains the final
+backstop behind this boundary; the DGR-028+ native build lane must embed the
+marker via the reserved CMake ABI-marker hook.
+
+## Executing-byte identity repair — 2026-07-18 controller follow-up
+
+A later controller review rejected the preceding remaining-boundary claim as
+insufficient for DGR-025: a separately built loadable shared object could copy
+all public lock values into both marker channels and receive the same
+`runtime_version` as a certified artifact. The repair now appends
+`+artifact.<sha256>` to the llama.cpp runtime axis, where the digest is computed
+from the exact bytes read by `attest_loaded_runtime`. Node and tracker parsers
+independently require this suffix. Consequently, copying lock values into a
+different loadable artifact produces a different recipe fingerprint; only the
+same artifact bytes can retain the same identity, and every new binary remains
+dark until certified.
+
+`test_copying_public_lock_values_cannot_forge_the_certified_runtime_identity`
+builds a second loadable artifact with byte-identical lock attestation but
+different executable bytes, and proves both its `runtime_version` and recipe
+digest differ from the accepted artifact. Conformance vectors were regenerated
+for the strengthened wire identity.

+# DGR-026 evidence — provision exact split-GGUF artifacts outside `/home`
+
+**Status:** implemented and verified this session; live re-review, not inherited credit.
+**Dependency:** DGR-025 (`evidence/DGR-025/README.md`) — read before changing code.
+
+## Objective
+
+Make exact split-GGUF inputs reproducibly available from mounted-drive
+storage, bound by a hashed manifest that fingerprints the source artifact,
+tokenizer/revision, and every split file, without embedding a quantization or
+split-topology assumption anywhere in product code.
+
+## What was found live (verified, not inherited)
+
+Per RALPH-CONTEXT, legacy pass states were not trusted. No prior split-GGUF
+manifest or provisioning module existed:
+`grep -rln "provision\|mounted-drive" packages/ scripts/ tests/` found only
+`packages/node/meshnet_node/recipe_drivers.py`'s existing
+`artifact_storage_root` `/home` check (benchmark config validation, not
+provisioning) and the RALPH-CONTEXT/prd.json prose itself. The pre-existing
+`packages/node/meshnet_node/downloader.py` is a different mechanism entirely —
+it fetches HuggingFace SafeTensors *layer* shards into `~/.cache/meshnet/shards`
+(i.e. under `/home` by default) for the existing Tracker route/download flow,
+with no manifest binding or split-GGUF concept; it was left untouched because
+this story's provisioning target (mounted-drive-only, hash-manifest-bound
+split-GGUF files) is a distinct concern from that peer/HF shard cache.
+
+Two existing conventions were read and reused directly rather than
+reinvented:
+
+- `packages/node/meshnet_node/glm_alpha/manifest.py` (DGR-017) — the
+  per-shard identity manifest shape (name/size/sha256/revision, aggregate byte
+  cross-check) that this story's manifest schema follows for source/split
+  records.
+- `packages/node/meshnet_node/runtime_recipe.py`'s `DerivativeBinding` (DGR-003)
+  — the half-open (`shard_start`, end-exclusive `shard_end`) range convention
+  a split is bound to its source under; this story's optional per-split range
+  fields use the same convention so a route already speaks the same layout
+  language.
+- `packages/node/meshnet_node/recipe_drivers.py`'s `_validate_config` — the
+  exact `/home` rejection shape (`not root.is_absolute() or root ==
+  Path("/home") or Path("/home") in root.parents`) this story's
+  `reject_home_path` mirrors for provisioning destinations.
+
+## What was built (this story's change)
+
+### `packages/node/meshnet_node/split_gguf/` (new package)
+
+- **`manifest.py`** — `SplitArtifactManifest`: binds a `SourceArtifact`
+  (artifact id, repo, 40-hex pinned revision, sha256, size), a `TokenizerRef`
+  (repo, 40-hex pinned revision, sha256), a free-form `quantization` string
+  (a recipe input, not a validated enum), and a tuple of `SplitFile` records —
+  each with `name`, `size_bytes`, `sha256`, `role`, optional `url`, and an
+  optional half-open (`shard_start`, `shard_end`) range. `total_bytes` is
+  cross-checked against the sum of split sizes (rejects a hand-edited "it fits
+  now" manifest, mirroring DGR-017's aggregate check); duplicate names and
+  duplicate content hashes are rejected; revisions must be full 40-hex commits
+  (a branch/tag/short-SHA is refused). Nothing in this module names a
+  quantization, shard count, or layout — `test_quantization_and_topology_are_manifest_data_not_constants`
+  parses a single-split, differently-quantized manifest to prove it.
+- **`provision.py`** — `provision_split_artifact(manifest, dest_dir, fetch)`:
+  for each split, reuses an already-correct final file untouched (idempotent
+  re-run), discards and re-fetches a file with the wrong size/hash rather than
+  trusting it, stages fetches as `<name>.partial` so an interrupted run
+  resumes from the exact byte offset already on disk (a stale partial *larger*
+  than the manifest size is discarded and restarted, never trusted), and
+  promotes a partial to its final name only once its SHA-256 matches the
+  manifest exactly — a short, truncated, or hash-mismatched split is deleted
+  and raises `SplitProvisionError` rather than being silently accepted.
+  `verify_provisioned_split_artifact` is the standalone completeness/hash
+  check a downstream loader or a resumed run should call before trusting a
+  directory. `reject_home_path` is the fail-closed `/home` gate, called by
+  every entry point (provision, verify) before touching disk, and does not
+  require the destination to exist yet (provisioning creates it), unlike
+  `recipe_drivers.py`'s `strict=True` benchmark-root check. Two `SplitFetcher`
+  implementations are provided: `local_directory_fetcher` (byte-for-byte copy
+  with seek-based resume from a local directory — used by tests and for
+  splits already staged/mirrored on another local or mounted path) and
+  `http_split_fetcher` (Range-header resume over HTTP/HTTPS for real network
+  provisioning, with a fallback to a full restart if a server ignores
+  `Range`).
+
+### `scripts/provision_split_gguf.py` (new)
+
+A CLI wrapper: `--manifest`, `--dest`, optional `--source-dir` (uses
+`local_directory_fetcher` instead of downloading each split's manifest `url`).
+Manually smoke-tested end to end this session (see Commands below), including
+a real `/home` destination rejection through the CLI, not just the library.
+
+### Tests (new, deterministic, offline, GPU-free, download-free)
+
+- `tests/test_split_gguf_manifest.py` (19 tests) — resolves source/tokenizer/
+  splits correctly; quantization/topology are manifest data, not constants
+  (single-split, differently-quantized manifest parses); digest stability;
+  rejects: split declaring only one of `shard_start`/`shard_end`, an empty
+  range, a missing required field, a duplicate split name, two splits sharing
+  one content hash, an inconsistent aggregate byte total, a shrunk split size,
+  a truncated SHA-256, a branch-name source/tokenizer revision, an unsupported
+  schema version, an empty `splits` array.
+- `tests/test_split_gguf_provision.py` (12 tests) — covers exactly the four
+  scenarios the acceptance criteria name:
+  - **`/home` rejection** — a `/home/...` destination, `/home` itself, and a
+    nested `/home` subdirectory are refused by both `provision_split_artifact`
+    and `verify_provisioned_split_artifact`; a mounted-drive-style path is
+    accepted.
+  - **Interrupted download → resume** —
+    `test_an_interrupted_partial_download_resumes_from_its_exact_byte_offset`
+    plants a half-written `.partial` file, wraps the fetcher to record the
+    `resume_from_bytes` argument it's actually called with, and asserts
+    resume starts from the exact prior byte count (not 0) while an
+    unstarted split still starts from 0; a stale partial larger than the
+    manifest size is discarded and restarted from scratch.
+  - **Missing split** — a missing local source file raises
+    `SplitProvisionError` during provisioning; a split absent from an
+    already-provisioned destination is caught by
+    `verify_provisioned_split_artifact`.
+  - **Hash mismatch** — a same-size-but-wrong-content source file is rejected
+    (`SplitProvisionError`, and neither the corrupt final file nor its
+    `.partial` is left on disk); a destination file with the wrong hash (but
+    right size) is not trusted and is transparently replaced by a correct
+    re-fetch; a destination corrupted after a prior successful provisioning
+    run is caught by `verify_provisioned_split_artifact`.
+  - Also: idempotent no-op re-run over already-complete, correctly-hashed
+    splits (verified with the source files deleted, proving no re-fetch was
+    attempted).
+
+## Acceptance criteria → evidence
+
+1. **Exact manifest binding source artifact, tokenizer/revision, every split's
+   name/size/range-or-role/hash** — `SplitArtifactManifest`/`SourceArtifact`/
+   `TokenizerRef`/`SplitFile` in `manifest.py`; covered by
+   `test_split_gguf_manifest.py`.
+2. **Resumable, hash-verifying provisioning targeting mounted-drive storage;
+   refuses `/home` and incomplete/mismatched splits** —
+   `provision_split_artifact`/`verify_provisioned_split_artifact`/
+   `reject_home_path` in `provision.py`; covered by
+   `test_split_gguf_provision.py` and the CLI smoke test below.
+3. **Quantization/topology are manifest/recipe inputs, not hardcoded** —
+   `quantization` is a free-form string; `SplitFile.shard_start`/`shard_end`
+   are optional per-split fields; no product module names a quant, node
+   count, or range constant. Verified by
+   `test_quantization_and_topology_are_manifest_data_not_constants` (a
+   single-split, differently-quantized manifest parses without any code
+   change).
+4. **Deterministic model-download-free tests covering interrupted resume,
+   missing split, hash mismatch, `/home` rejection** — see the Tests section
+   above; all fixtures are in-memory or tiny `tmp_path` files, no network
+   access anywhere in the suite.
+5. **Gates + this handoff** — below.

+## Gotcha reproduced (pre-existing, documented pattern)
+
+Before touching anything, `.scratch/distributed-gguf-runtime/prd.json`'s
+top-level `sourceOfTruth`/`qualityGates`/`metadataSchema`/`milestones`/
+`supersededStories`/`branchName` fields were already missing in the working
+tree at session start (this is the fourth documented occurrence of the
+round-trip-drop bug noted in DGR-018/019/020/025's evidence — `userStories`
+itself was unaffected, only these top-level fields). Restored them from
+`git show HEAD:.scratch/distributed-gguf-runtime/prd.json` before making any
+DGR-026 edit; `scripts/ralph_prd_schema.py validate` reported `OK` both before
+and after the restoration, confirming (again) that this validator does not
+catch the drop on its own.
+
+## Limitations
+
+- `http_split_fetcher` (the real network-download path) is exercised only by
+  manual code review and the CLI's argument wiring, not by an automated test —
+  by design, since the default suite must stay network-free. Its Range-header
+  resume logic shares the same `provision_split_artifact` byte/hash
+  verification as the tested `local_directory_fetcher` path, so the
+  fetcher-specific risk surface is the HTTP interaction itself (server Range
+  support, redirects, auth), not the resume/verify contract.
+- No real DeepSeek V4 Flash split-GGUF manifest exists yet — this story
+  defines the manifest schema and provisioning tooling; DGR-044/DGR-045
+  (below) are what will populate a real manifest against the pinned target.
+- `python3 -m pytest -q` (unscoped full-repo sweep) was not run this session;
+  DGR-019/DGR-020/DGR-025's evidence already recorded several pre-existing,
+  unrelated failures in that sweep (missing optional `zstandard`/
+  `langchain_openai` dependencies, unrelated billing/dynamic-routing/cache
+  tests, and `tests/test_shard_runtime_harness.py`'s `grpc` import
+  requirement). This story's own targeted suites, `test_ralph_prd_schema.py`,
+  `compileall`, and `git diff --check` are all green as recorded above.
+- Tracker routing, load balancing, billing, telemetry, and relay semantics are
+  untouched; this story adds a new, isolated package and does not modify any
+  existing runtime/identity module.
+
+## Dependency handoff
+
+- **DGR-044** (DeepSeek V4 Flash target contract): when pinning the real
+  target's split-GGUF artifact, express it as a
+  `meshnet_node.split_gguf.manifest.SplitArtifactManifest` — `source.sha256`
+  is the whole-model artifact digest DGR-003's `ArtifactIdentity.source_digest`
+  compares against, and each `SplitFile`'s `shard_start`/`shard_end` should
+  match the exact ranges the route's `ShardIdentity`s claim.
+- **DGR-045** (V4 GGUF tensor/layer-ownership inventory): once layer ownership
+  per split is derived, populate each `SplitFile.role` and
+  `shard_start`/`shard_end` from that inventory rather than restating them —
+  this manifest is meant to bind, not redefine, DGR-045's ownership finding.
+- Any future story that actually provisions a real split-GGUF artifact onto
+  mounted-drive storage should call `provision_split_artifact` with
+  `http_split_fetcher` (or `local_directory_fetcher` if mirroring from another
+  local/mounted path) and must call `verify_provisioned_split_artifact` before
+  trusting a directory a prior run may have left partially populated.

+# DGR-028 evidence — numbered llama.cpp patch-stack verification
+
+**Status:** implementation complete; independently re-verified in a fresh Ralph session (2026-07-22) against live source and the real cached upstream checkout, per `RALPH-CONTEXT.md`'s "inspect live source/tests rather than trusting legacy pass states" mandate. `prd.json`'s `DGR-028.passes` is now `true`.
+**Authority:** local `prd.json` is authoritative; live Gitea #12 is a projection.
+**Upstream pin:** `e920c523e3b8a0163fe498af5bf90df35ff51d25` (`llama.cpp`)
+
+## Implemented
+
+- Replaced the stale non-applying range-loader patch with an ordered five-patch stack whose concerns are separated into build marker, dense-Llama owned-range loading, filtered state reporting, boundary I/O fail-closed guard, and worker range-report hook plus native fixture.
+- Added `patches/UPSTREAM-ASSUMPTIONS.json`, binding each patch to the exact pre/post blob IDs and named upstream API assumptions for every touched file.
+- Extended `scripts/llama_cpp_dependency.py` so `apply`, `reverse`, and `verify` validate patch digests, exact ordered coverage, assumptions, first-incompatible-patch behavior, pristine/patched Git trees, touched paths, license/attribution preservation, and exclusion of Meshnet control-plane concerns.
+- `verify` performs the complete apply/check/reverse cycle and leaves the cached detached upstream checkout pristine.
+- Updated the lock's exact patched tree and patch checksums. No model artifact was downloaded or created.
+
+## Controller repairs during verification
+
+The preserved Kimi output was not accepted from prose. Initial controller execution found and repaired:
+
+1. a missing `_git` helper that made the dependency verifier raise `NameError`;
+2. assumptions resolved relative to the repository root rather than the llama manifest directory;
+3. the documented `verify`/`reverse` contract was not wired into the CLI or apply path;
+4. assumptions and control-plane/license boundaries were defined but never enforced during apply;
+5. a stale Python test hardcoded the old two-patch count;
+6. the native fixture made an invalid strict resident-buffer-size comparison. Backend allocation granularity made a two-layer range and tail endpoint incomparable even though exact tensor ownership and mapped-byte behavior were correct. The assertion was narrowed to the deterministic mapped-byte invariant, and patch/blob/tree digests were regenerated.
+
+## Verification
+
+All commands below were re-executed in the continuation session on the exact
+pin; results are from that run.
+
+```text
+cd packages/node/native/llama/patches && sha256sum -c SHA256SUMS

+
+python scripts/llama_cpp_dependency.py inspect
+# exact commit/tree, MIT license, five-patch series, no model downloads

+# exit 0
+```
+
+Focused native gate against the patched exact pin (apply first because `verify`
+intentionally restores the source checkout to pristine state, then reverse after
+the test):
+
+```text
+python scripts/llama_cpp_dependency.py apply --source-dir build/llama.cpp/source

+```
+
+Build-directory note: `build/llama.cpp/dgr028-build` is a stale configure from
+before the fixture repair and does not know the
+`test-meshnet-range-ownership` target (`No rule to make target`); the working
+configure lives in `build/llama.cpp/dgr028-build-verify` with the flag set
+recorded above (verified against its `CMakeCache.txt`). Both directories are
+derived artifacts under the ignored `build/` tree; no tracked work depends on
+them.
+
+A broad `cmake --build ... --target test` was also attempted after building only the focused target. It reported 52 unrelated tests as `Not Run` because their executables had not been built, and exposed the original focused-fixture assertion failure. It is not presented as a full-suite gate. After the fixture repair, the exact focused target was rebuilt and its CTest passed as shown above.
+
+A controller Python full-suite run (`python3 -m pytest -q`) was also executed
+and is not represented as green: `12 failed, 1072 passed, 22 skipped, 2
+warnings`. The failures are outside the DGR-028 changed paths: unavailable
+optional `zstandard`/`langchain_openai` dependencies, unrelated billing/
+dynamic-routing/tracker expectations, and the stale DGR-023 local projection.
+The exact dependency verifier, patch apply/check/reverse cycle, Python tests,
+and focused native CTest remain green as recorded above.

+- DGR-029 may use the now-verifiable exact patch stack for the deterministic native CPU build lane. DGR-034 owns real dense-Llama range behavior and memory evidence.

+## Independent re-verification (2026-07-22, fresh Ralph session)

+The prior evidence above was carried over from an earlier session that recorded

+not independently reverify because `build/` was not present at commit time

+`cmake` is not installed in this environment (`which cmake` fails), so the
+native CMake/CTest build claim from the prior session (`test-meshnet-range-ownership`
+1/1 Passed) could **not** be independently re-executed here; it is neither
+re-confirmed nor retracted, just carried forward from `7da90ef` without a new
+build-verified claim in this session. Everything at the Python/Git contract
+level — patch digests, assumption-blob enforcement, apply/reverse against the
+real cached upstream checkout, patched-tree identity, and pristine-restore —
+was independently re-verified against live source in this fresh session.

+## prd.json repair (unrelated to DGR-028 itself)
+
+Before editing `DGR-028.passes`, `prd.json` was found with its top-level
+`sourceOfTruth`/`qualityGates`/`metadataSchema`/`milestones`/`supersededStories`
+fields silently dropped again (`branchName` was also missing but had already
+been restored by a prior in-flight edit) — the same ralph-tui round-trip bug
+documented for DGR-019/DGR-020. Unlike those occurrences, `userStories` in the
+working tree was *not* unchanged: it already carried legitimate uncommitted
+`passes: true`/`completionNotes` updates for DGR-019, DGR-020, DGR-024, and
+DGR-026 from other stories' sessions. The missing top-level sections were
+restored from `git show HEAD:.scratch/distributed-gguf-runtime/prd.json`
+while preserving the current `userStories` array verbatim, then
+`DGR-028.passes` was set `true` with `completionNotes` added, and
+`.scratch/distributed-gguf-runtime/issues/028-implement-numbered-patch-stack-apply-and-verification.md`
+was regenerated via `scripts/ralph_prd_schema.py render` (which only prints;
+the caller must redirect it into the issue file — it does not write in
+place). `python3 scripts/ralph_prd_schema.py validate` and
+`python3 -m pytest -q tests/test_ralph_prd_schema.py` (108 passed) both pass
+against the repaired file.

+# DGR-029 evidence — native CMake skeleton and deterministic CPU lane
+
+**Status:** implementation complete, live-verified in this session (2026-07-22).
+**Authority:** local `prd.json` is authoritative; Gitea is a projection.
+**Upstream pin:** `e920c523e3b8a0163fe498af5bf90df35ff51d25` (`llama.cpp`, from `UPSTREAM_LOCK.json`).
+
+## What existed before this session
+
+`scripts/llama_cpp_dependency.py` already had `build()`, `smoke()`, and `reproduce()`
+functions and `UPSTREAM_LOCK.json` already had a `build` section (both landed as part
+of DGR-028's commit `7da90ef`), but:
+
+- No test in `tests/test_llama_cpp_dependency.py` ever exercised `build`/`smoke`/`reproduce`
+  — only `fetch`/`apply`/`reverse`/`inspect` had coverage.
+- `cmake` was not installed in the DGR-028 session's environment ("`cmake` is not installed
+  in this environment," per its evidence), so this lane was never actually run end to end;
+  DGR-028's own live-verified CTest evidence used a one-off manual `cmake`/`ctest` invocation
+  with `-DLLAMA_BUILD_TESTS=ON` outside this driver, against a build directory that no longer
+  exists in this session.
+- The locked `configure_flags` did not force CPU-only backend options (`GGML_CUDA`/`GGML_HIP`/
+  `GGML_VULKAN`/`GGML_METAL`/`GGML_BLAS`) — relying on upstream per-platform defaults (which
+  happen to default OFF on Linux, but are undocumented and platform-dependent), and
+  `LLAMA_BUILD_TESTS` was `OFF`, so no CTest lane existed at all — only a `--help` smoke check
+  against the unrelated stock `llama-gguf-hash` tool.
+
+This session found and closed those three gaps rather than re-implementing from scratch.
+
+## What changed in this session
+
+- `packages/node/native/llama/UPSTREAM_LOCK.json`: the `build` section's `configure_flags` now
+  explicitly force `-DGGML_CPU=ON` and `-DGGML_CUDA=OFF -DGGML_HIP=OFF -DGGML_VULKAN=OFF
+  -DGGML_METAL=OFF -DGGML_BLAS=OFF`, so the CPU lane can never silently gain a GPU/BLAS backend
+  from a build machine's ambient toolchain. `-DLLAMA_BUILD_TESTS` flipped `OFF` → `ON` (required
+  so the `test-meshnet-range-ownership` CTest target exists at all — configuring
+  `LLAMA_BUILD_TESTS=ON` does not itself build every upstream test, only registers them; the
+  `native_targets` list still controls what actually gets compiled). Added `native_targets` entry
+  `test-meshnet-range-ownership` and a new `ctest_regex` field
+  (`"^test-meshnet-range-ownership$"`) naming the exact deterministic model-free fixture CTest
+  added by DGR-028's patch 0005.
+- `scripts/llama_cpp_dependency.py`: factored `_cmake()`'s override/PATH/venv-sibling resolution
+  into a shared `_toolchain_binary(name, env_var)` and added `_ctest()` using the same resolution
+  (`CTEST` env override, PATH, or the sibling of the resolved `cmake` binary's environment). Added
+  `ctest_lane(build_dir)`, which loads the lock's `ctest_regex` and runs
+  `ctest --test-dir <build_dir> -R <regex> --output-on-failure`, printing output on success and
+  raising `DependencyError` (via the existing `_run` wrapper, which already attaches
+  stdout/stderr detail) on failure. Added a `ctest` CLI subcommand (`--build-dir`). Wired
+  `reproduce()` to run `fetch → apply → build → smoke → ctest_lane → reverse`, so a full
+  `reproduce` run leaves the cached upstream checkout pristine afterward (previously `reproduce()`
+  left the source permanently patched, which would have broken every *subsequent* `reproduce`/
+  `fetch` call's `require_clean=True` cleanliness check).
+- `tests/test_llama_cpp_dependency.py`: added
+  `test_build_config_locks_an_explicit_cpu_only_deterministic_lane` (offline; asserts the lock's
+  `configure_flags` are CPU-only and that `ctest_regex`/`native_targets`/`smoke_binary` all agree
+  with each other and with `patched_paths`) and
+  `test_ctest_lane_raises_an_actionable_error_for_a_failing_named_test` (gated on `cmake`
+  availability via a `requires_cmake` marker mirroring `test_native_identity_emission.py`'s
+  `requires_cc` pattern; builds a tiny synthetic two-test CMake project — not the full llama.cpp
+  tree, so it runs in about a second — and proves `ctest_lane()` both passes silently on a passing
+  named test and raises `DependencyError` naming the failing test on a failing one).
+
+## Toolchain note
+
+Neither the ambient system Python nor `.venv-rocm` has `cmake`. This session installed `cmake`
+(the PyPI wheel that bundles prebuilt binaries, version 4.4.0) into the pre-existing repo-root
+`.venv` used by earlier DGR-024/DGR-026 sessions (`.venv/bin/cmake`, `.venv/bin/ctest`), which was
+already on-disk from a prior session but had never had `cmake` installed into it. All commands
+below were run with that `.venv/bin` prepended to `PATH`. This is the same "disposable venv for a
+lightweight optional dependency" pattern DGR-024 used for `grpc`.
+

+
+## Ensuring build success does not advertise capability
+
+- The locked `configure_flags` disable every accelerator backend explicitly
+  (`GGML_CUDA/HIP/VULKAN/METAL/BLAS=OFF`) rather than relying on per-platform defaults, so a
+  successful configure/build can only ever mean "the CPU reference backend compiled" — never an
+  accelerator claim, and never dependent on whether the build host happens to have a GPU SDK
+  installed.
+- `meshnet-build-metadata.json` (written by `build()`) records `model_downloads: false` and
+  `semantic_certification: false` alongside the exact commit/patch/flag identities — the artifact
+  itself, not just prose, states this build proves toolchain compilation only.
+- The two targets actually compiled are `llama-gguf-hash` (a stock upstream file-hashing utility;
+  no inference) and `test-meshnet-range-ownership` (a model-free fixture that writes a tiny
+  synthetic GGUF and asserts range-ownership bookkeeping — no real model, no generation, no
+  numerical/backend correctness claim). Neither exercises inference, MoE, attention, or any
+  DeepSeek V4 semantic path.
+
+## Changed files
+
+- `packages/node/native/llama/UPSTREAM_LOCK.json`
+- `scripts/llama_cpp_dependency.py`
+- `tests/test_llama_cpp_dependency.py`
+- `.scratch/distributed-gguf-runtime/prd.json`
+- `.scratch/distributed-gguf-runtime/issues/029-create-the-native-cmake-skeleton-and-deterministic-cpu-lane.md`
+- `.scratch/distributed-gguf-runtime/evidence/DGR-029/README.md` (new)
+
+## Limitations
+
+- This is a toolchain/compile-and-link gate plus one model-free ownership-bookkeeping fixture —
+  it proves the CPU lane builds and the DGR-027/DGR-028 patch stack functions structurally on
+  CPU. It proves nothing about real-model correctness, memory-fit, performance, or any
+  backend/model/recipe certification; `stock_glm_limitations` in `UPSTREAM_LOCK.json` and DGR-028's
+  own limitations continue to apply unchanged.
+- `cmake`/`ctest` are not installed system-wide or in `.venv-rocm` in this environment; they were
+  installed only into the pre-existing repo-root `.venv` for this session's verification (and for
+  the new gated pytest test, which is skipped in any environment lacking `cmake`). A future session
+  without that `.venv` (or without re-installing `cmake` into it) will see the same "cmake is
+  unavailable" actionable failure demonstrated above, not a silent pass.
+- Only the two named targets are compiled (`llama-gguf-hash`, `test-meshnet-range-ownership`); a
+  broad `cmake --build ... --target test` / full upstream test suite is out of scope here, exactly
+  as DGR-028 recorded ("not presented as a full-suite gate").
+- CUDA/ROCm/Vulkan/Metal compile lanes remain unimplemented; this story only establishes the CPU
+  lane "before accelerator matrix work," per its objective. Those lanes are separate future work.
+
+## Dependency handoff
+
+DGR-030 and DGR-034 (this story's declared blockers) may rely on: an out-of-tree, CPU-only,
+explicit-backend-flag native build (`scripts/llama_cpp_dependency.py build`/`reproduce`) that
+compiles the exact DGR-027/DGR-028 patched pin and runs a real CTest lane
+(`test-meshnet-range-ownership`) proving the patch stack's range-ownership bookkeeping compiles
+and passes on CPU. Any accelerator (CUDA/ROCm/Vulkan/Metal) lane, any real-model load, and any
+backend/model/recipe capability certification remain unimplemented and must not be assumed from
+this story's green build alone.

Enumerates all four required lanes: controlled-safetensors and whole-model-gguf reference the pre-existing immutable DGR-001 lock (meshnet_node.performance_contract) rather than re-defining it; dense-distributed-gguf and v4-flash-distributed are newly locked with fixed prompts, context/output lengths, greedy sampling, concurrency levels, hardware, and metrics. Alpha requires correctness plus a useful-speed threshold gated on an explicit human_approval structure (required=true, approved=false) that DGR-054 must fill in against real evidence, not an automatic ratio check. Beta adds concurrency, long-context, failure, and sustained-throughput thresholds. Quantization and 2-4/10-plus stage counts are recorded only as named certification-scenario labels; a structural test asserts no product module under packages/node/meshnet_node hardcodes those labels. gain_attribution separates quantization/model-fit metrics from runtime/transport/batching/kernel metrics into disjoint sets. The contract's own content-hash digest is verified on every load against a digest pinned in code, so a later edit is rejected rather than silently trusted, matching the existing meshnet_node.glm_alpha.contract precedent. Also restored .scratch/distributed-gguf-runtime/prd.json's top-level sourceOfTruth/qualityGates/metadataSchema/milestones/supersededStories, which an unrelated prior working-tree edit (userStories content was untouched) had silently dropped and which broke 56 tests in tests/test_ralph_prd_schema.py before this session started."

Ran the canonical opt-in local-real benchmark (meshnet_node.recipe_benchmark), Ed25519-signed the report with the existing DGR-001 evidence key, and evaluated it against the immutable v1 performance_contract (min_decode_speedup=1.25, max_resident_memory_ratio=0.75, min_quality_exact_match_rate=0.90, ...). Result reproduces DGR-001 within normal machine variance: zero failures on every recipe/concurrency, meaningful speed and memory-fit benefits (decode 2.02x-4.19x, aggregate throughput 4.47x-4.83x, resident memory 0.28x-0.57x of the safetensors reference), but the near-lossless BF16 GGUF quality lane again fails the quality gate (exact match 0.33 vs required >=0.90) -> verdict is again `stop`, confirming the run/kernel speed and memory-fit benefit is real and separable from the still-unexplained GGUF quality mismatch (a quantization/model-fit-adjacent effect, not a runtime/kernel throughput effect). No distributed implementation result was consulted or ingested.

+The worktree is correct. There's a pre-existing deletion of `.ralph-tui/config.toml` I must preserve. Let me check the prd.json for DGR-002 and whether any native/proto work already exists.

So the C++ build/test can't be *executed* here, but I can still write reproducible C++ generation/build wiring + test source and gate it to skip honestly.

+DGR-002 is complete. Here's what I delivered and verified.
+
+## What was built
+The versioned Protobuf/gRPC data-plane contract between Python and C++ Shards (ADR-0024), plus reproducible codegen/build wiring and round-trip + cross-language compatibility tests in both languages. It's purely additive — no existing runtime code was touched.
+
+**New files:**
+- `packages/node/native/proto/shard_runtime.proto` — package `meshnet.shard.v1`, proto3. Service `ShardRuntime` with `GetCapability`, `Health`, `ActivateSession` (one long-lived bidirectional stream per Activation Seam), `Release`, `Cancel`. `MessageHeader` carries every required identifier (schema version, work ID, Route Session ID, route epoch, artifact/recipe fingerprint, shard range + effective start, phase, position, idempotency step, cache expectation, compression, checksum). `TensorBundle`/`NamedTensor`/`TensorFragment` is the versioned named-tensor bundle with bounded fragments; `PrefillChunk` gives bounded chunking and `DecodeStep` the fast path; `FlowControl`, structured `Status`, and `SessionOpen.deadline_unix_nanos` cover flow control, errors, and relay-carried deadlines.
+- `packages/node/meshnet_node/native_protocol/` — on-demand codegen loader + checksum/fragment helpers.
+- `packages/node/native/` — `scripts/generate_python.py`, `generate_cpp.sh`, `CMakeLists.txt`, `tests/roundtrip_test.cpp`.
+- `tests/test_native_shard_protocol.py` — 12 tests.
+
+## Verification (real results)
+- Targeted pytest: **11 passed, 1 skipped** in the default env (the C++ test skips cleanly when the toolchain is absent); **12 passed** with the toolchain.
+- `compileall packages tests` exit 0; `git diff --check` clean.
+- Full `pytest -q`: **704 passed, 14 skipped, 11 failed** — the 11 are pre-existing tracker/routing/benchmark/toploc failures unrelated to this story, which I reproduced identically on a clean tree with all DGR-002 files removed (`11 failed, 3 passed`).
+- The C++ path was executed for real (a host protobuf 33.1 toolchain + `.venv` cmake): selftest `128 bytes`, ctest `1/1`, and the Python↔C++ cross-language driver passed in both directions.
+
+## Notable findings (recorded in progress.md + evidence)
+- The `.venv` installs the meshnet packages editable via a PEP 660 meta-path finder pointing at the **main** checkout, so standalone scripts must derive paths from `__file__` rather than `import meshnet_node`.
+- Two real bugs I hit and fixed while testing: a non-reentrant `Lock` deadlock in the loader (now `RLock`), and protobuf 7.x's upb backend lacking `UnknownFields()` (the forward-compat test now asserts re-serialization behaviorally).
+- `grpcio-tools`' bundled protoc has no C++ generator, and the default env lacks protoc/cmake/protobuf-dev — so the C++ test skips by default and DGR-004/DGR-008 should pin that toolchain. This is documented honestly as a limitation.

+Evidence is at `.scratch/distributed-gguf-runtime/evidence/DGR-002/` (README, commands.txt, results.json). The issue is set to `Status: done`, `passes: true` for DGR-002 only, and the pre-existing `.ralph-tui/config.toml` deletion was preserved. No commits were created.

+Targeted tests pass and DGR-002's working-tree changes are isolated. Now I'll assess against the acceptance criteria. The contract is solid but has genuine gaps I should close before marking done:
+
+1. **AC1** requires the same *prompts, context lengths, output lengths, sampling policy* — these aren't encoded in the versioned contract, so "same across recipes" isn't locked.
+2. **AC2** requires explicitly *separating correctness/quality lanes from performance/fit lanes* — currently only an implicit `output_drift`, no explicit quality policy stating BF16≠Q2_K.
+3. **AC5** — the gate thresholds (`1.10` speedup, `0.5` artifact ratio) are hardcoded in code, not in the versioned JSON that DGR-014 must consume without changing thresholds.
+
+I'll close these three. Let me strengthen the contract module.

+All acceptance criteria are met. Summary of what I did for **DGR-006 — Architecture-defined boundary input/output**:
+
+## Implementation
+
+**`packages/node/meshnet_node/boundary_adapter.py`** (new) — the boundary contract:
+- **Fail-closed certification** — `certified_architecture()` maps only dense-Llama spellings (`dense-llama`/`llama`/`LlamaForCausalLM`/...) to an adapter; everything else (Qwen3, Mixtral, gpt2, empty/None) raises `UncertifiedArchitectureError`.
+- **`BoundaryAdapter`** drives a duck-typed `ShardComputation` and enforces per-role rules: head embeds token IDs (refuses a bundle); middle/tail bypass embedding (refuse token IDs); non-tail emits the **unnormalized** residual with all position rows (no final norm, no LM head, no pruning); tail normalizes → LM head → prunes to last row → samples via an explicit `SamplingContract` (greedy).
+- **`BoundaryBundle`** — versioned named-tensor bundle carrying the residual + positions + seam `next_layer`, with `pack()`/`unpack()` for disjoint-process round-trip and `named_tensor_fields()` mapping onto the DGR-002 `NamedTensor` shape.
+
+**`tests/test_boundary_adapter.py`** (new) — a pure-numpy dense-Llama reference (RMSNorm + RoPE + SwiGLU) satisfying the same protocol; 22 tests proving whole-model vs **two-range and three-range** prefill + greedy-decode parity (identical greedy tokens, logits `atol=1e-6`), plus every contract/fail-closed path.
+
+## Verification (real results)
+- Targeted: **22 passed**
+- `compileall`: exit 0 · `git diff --check`: clean
+- Full suite: `20 failed, 715 passed, 13 skipped, 12 errors` — **clean-tree reproduction** (files moved aside) gives `693 passed` with a **byte-identical** failure/error set, proving DGR-006 introduced zero failures. The pre-existing failures (protobuf gencode mismatch + tracker/routing/optional-dep) are recorded in `results.json`.
+
+torch/transformers aren't installed in the default venv, so the numpy reference is the only deterministic, GPU-free, download-free way to prove parity — the identical protocol will be satisfied by the C++ worker (DGR-008). Native C++ / llama.cpp patch gates are N/A (no native code touched), documented in evidence.
+
+Evidence written to `.scratch/distributed-gguf-runtime/evidence/DGR-006/` (README + commands.txt + results.json); progress log and issue `Status: done` updated. Pre-existing working-tree changes preserved; no commits created.

+
+## Summary
+
+Implemented range-aware dense-Llama ownership so the node reports and admits only the tensors it actually loads:
+
+- `blk.N.*` tensors are selected strictly by assigned layer range.
+- Embeddings are owned at the head only, while final norm / LM head are owned at the tail only, including tied embeddings.
+- Derivative sub-GGUF slices must carry source and slice hashes and cannot claim final artifact semantics.
+- The authoritative loaded range and endpoint ownership now come from backend proof state, not CLI shard claims.
+- Registration, capability reports, admission fingerprints, and tracker state now carry the backend-derived ownership proof.
+
+The result is a shard model that can reason about memory and admission from owned tensors instead of pretending the full model was loaded.
+
+## Files changed
+
+- `packages/node/meshnet_node/gguf_ownership.py` - dense-Llama tensor selection and authoritative ownership helpers.
+- `packages/node/meshnet_node/capability.py` - shard reports now carry endpoint ownership and parse it round-trip.
+- `packages/node/meshnet_node/doctor.py` - capability reports now use backend-derived loaded range and endpoint ownership.
+- `packages/node/meshnet_node/testing.py` - test capability reports now mirror the authoritative ownership path.
+- `packages/node/meshnet_node/admission.py` - admission compatibility fingerprints now include authoritative range/ownership context.
+- `packages/node/meshnet_node/model_backend.py` - loaded-range and endpoint-ownership properties on `TorchModelShard`.
+- `packages/node/meshnet_node/startup.py` - registration payloads now use the proof-driven shard range.
+- `packages/tracker/meshnet_tracker/capability.py` - tracker capability state preserves endpoint ownership.
+- `tests/test_gguf_ownership.py` - dense-Llama ownership selection, derivative-slice guard, and memory-scaling tests.
+- `tests/test_node_capability.py` - capability report ownership round-trip tests.

+All quality gates pass and the work is complete. Summary of DGR-007:
+
+## DGR-007 — Isolated concurrent local Hot KV State ✅
+
+**New files (purely additive):**
+- `packages/node/meshnet_node/hot_kv_state.py` — the KV/session manager
+- `tests/test_hot_kv_state.py` — 22 tests + a pure-numpy KV-cached dense-Llama reference
+
+**What it delivers:**
+- **`HotKvStateManager`** maps `(session_id, route_epoch)` → an isolated `SessionCache`, allocating `LayerKvCache` **only for owned layers**. It owns all cache mutation so eviction/accounting/isolation live in one place.
+- Full lifecycle: `open`/`append` (prefill + decode), `truncate`, `release`, plus **TTL + LRU (session-cap and byte-budget) eviction** and an explicit, serializable `CacheMiss` (unknown / evicted-ttl / evicted-lru / released / superseded-epoch / seq-len-mismatch) so the head re-prefills from token zero instead of corrupting output.
+- **Fails closed on identity:** stale route epochs → `StaleRouteEpochError`; mismatched KV recipe → `IncompatibleCacheRecipeError`; uncertified architecture → fails closed at recipe construction (reuses the DGR-006 gate).
+- **`KvBoundaryAdapter`** wraps the DGR-006 `ShardComputation` (+`run_layers_cached`) to run cached prefill/decode through the manager while honouring the boundary contract.
+
+**Correctness proof:** a KV-cached numpy dense-Llama (absolute-position causal mask over cached keys, post-RoPE key storage) reproduces stateless whole-model greedy tokens **bit-for-bit**, single-range and across a head/tail seam. Four sessions (interleaved round-robin **and** four real OS threads) decode with no cross-talk; releasing one returns memory to budget and leaves the others matching their references.
+
+**Gates (real results):**
+- Targeted: `22 passed`
+- `compileall packages tests`: exit 0 · `git diff --check`: exit 0
+- Full suite with files: `13 failed, 755 passed, 14 skipped`; clean-tree repro (files moved aside): `13 failed, 733 passed` — **identical FAILED set, passed −22**, so no new failures. All 13 are pre-existing tracker/routing/benchmark/toploc/doctor env failures, none touch KV. (No native C++/llama.cpp code touched — those gates are N/A, wired in DGR-008.)
+
+**Evidence:** `.scratch/distributed-gguf-runtime/evidence/DGR-007/{README.md,commands.txt,results.json}`; issue set to `Status: done`; `progress.md` updated. Pre-existing working-tree changes preserved; no commits created (left for manual review).

+[Bash] $ cd /run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime VP=/run/me...
+All gates pass and the working tree is preserved. Final summary:
+
+## DGR-013 complete — Harden failure, cancellation, and restart semantics
+
+**What was built** (deterministic, download-free, GPU-free, API-credit-free — layered on DGR-007 KV manager + DGR-012 scheduler, no new control plane):
+
+- **`packages/node/meshnet_node/failure_semantics.py`** (new):
+  - `DeadlineGuard` / `StreamTerminated` — deadline + heartbeat-loss terminate blocked stream ops.
+  - `CancellationToken` / `ShardCancellationGroup` — one cancel fans across **every** node-local Shard, releasing `(session, epoch)` KV + queued buffers.
+  - `IdempotencyLedger` / `UncertainMutationError` — duplicate steps replay the recorded token (no re-mutation); uncertain (mid-crash) mutations can never be silently replayed.
+  - `RestartController` — alpha failover opens a fresh epoch, drops prior-epoch KV, `assert_fresh_start` refuses to import unverified KV; restart re-prefills from token zero.
+  - `WorkStatus` / `WorkRecord` / `WorkLedger` — completed/cancelled/failed/unverified split; only completed is billable.
+  - `HardenedSessionRunner` + `run_with_failover` composes it all.
+- **`batch_scheduler.py`** (DGR-012 file, additive): `cancel()`, `DoneReason.CANCELLED/FAILED`, two telemetry counters. DGR-012's 16 tests unchanged.
+- **`tests/test_failure_semantics.py`** (new): 22 tests covering the whole matrix.
+- Evidence: `evidence/DGR-013/README.md`, `commands.txt`, `generate_evidence.py`, `results.json`.
+
+**Gates:** `test_failure_semantics.py` 22 passed; DGR-007/009/012 green; compileall exit 0; `git diff --check` clean. Full suite: **16 failed, 792 passed, 14 skipped** — the 16 are pre-existing/unrelated (tracker/startup/doctor/calibration; DGR-009 `worker_transport` recipe + HF-model/control-plane paths) and **reproduce identically with the two DGR-013 files removed** (verified). No native code touched, so those gates are N/A. Issue set to `Status: done`; changes left uncommitted per workflow; pre-existing working-tree changes preserved.

+The recipe manifest already carries a backend identifier, so the cleanest integration point is probably to select a backend implementation from that recipe instead of hardcoding Torch everywhere.

+I found the recipe catalogue is still Torch-only, which means a GGUF backend needs its own recipe identity as well as a client/server seam.

+I’m adding the GGUF backend adapter as a separate module so the Torch path stays untouched. The first cut will make the native worker a backend-shaped object with transport hooks and protocol metadata, then I’ll wire startup to choose it only for recipes that declare `llama.cpp`.
+I have the adapter module in place. Next I’m threading the startup decision through the recipe manifest so only recipes that explicitly declare the llama.cpp backend get the GGUF adapter, while the existing Torch recipes continue to use the current load path unchanged.
+I hit a Python call-shape issue while threading the optional backend into `TorchNodeServer`. I’m converting those three call sites to an explicit kwargs dict so the Torch path stays untouched and the GGUF backend only appears when the recipe asks for it.
+I’m adding focused tests around the new seam rather than broadening the existing startup suite. One test will prove the recipe gate chooses the GGUF backend only for the llama.cpp recipe, and another will prove the backend delegates the route/session metadata to its transport without altering the Torch surface.
+The code changes are in. I’m running the new GGUF test slice, the Python compile pass, and diff hygiene now to catch syntax or shape regressions before I touch the evidence and progress logs.

+The full suite is still running; I’ve got initial passes only. I’m polling until it finishes so I can report the actual outcome rather than guessing.

+The suite is failing broadly, but it’s still useful because the output is isolating the same existing tracker/unreachable and mixed test failures I’d need to report if I had to declare the tree unstable. I’m waiting for the final exit code so the record is exact.

+The next failure is more informative: the startup tests use an opaque model stub, so forcing config detection is the wrong behavior for the existing Torch path.

+Implemented the GGUF backend seam and recipe-gated startup path, then wrote the durable evidence and progress updates.
+
+What changed:
+- Added `packages/node/meshnet_node/gguf_backend.py`
+- Wired `packages/node/meshnet_node/startup.py` to inject the GGUF backend only for `backend_id == "llama.cpp"`
+- Added `llama-cpp-native` to `packages/node/meshnet_node/recipes.json`
+- Added `tests/test_gguf_backend.py`
+- Appended the DGR-009 entry to `.ralph-tui/progress.md`
+- Marked `.scratch/distributed-gguf-runtime/issues/09-integrate-the-native-worker-with-meshnet.md` as `Status: done`
+- Wrote `.scratch/distributed-gguf-runtime/evidence/DGR-009/README.md`
+
+Validation:
+- `python -m pytest -q tests/test_gguf_backend.py` -> 2 passed
+- `python -m pytest -q tests/test_node_admission.py::test_the_served_backend_is_loaded_with_the_recipe_that_was_validated tests/test_node_admission.py::test_backend_validation_failure_registers_nothing` -> 2 passed
+- `python -m compileall -q packages tests` -> exit 0
+- `git diff --check` -> exit 0
+
+Full-suite note:
+- `python -m pytest -q` is still not clean in this sandbox. The failures are dominated by tracker socket `PermissionError: [Errno 1] Operation not permitted` and a native protocol protobuf runtime mismatch when importing generated stubs.

+Blocked on the required certified dense-Llama artifact.
+
+I verified the local mounted-drive storage and found Qwen artifacts, but no certified dense-Llama GGUF or safetensors snapshot to run the real-model two-process acceptance. I added a durable handoff at [BLOCKED.md](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.scratch/distributed-gguf-runtime/evidence/DGR-010/BLOCKED.md) with the commands I ran and the exact unblock step.
+
+What’s missing:
+- A certified dense-Llama artifact on the configured mounted drive
+- A real `MESHNET_ENABLE_REAL_INFERENCE_TESTS=1` acceptance run against that artifact
+
+If you want, provide the artifact path or mount location and I’ll continue from there.

+I’ve mapped the live seams. The change is broader than one function, so I’m switching to an implementation plan: add a first-class runtime-recipe identity module, thread its fingerprint through node proof, tracker admission, and registration payloads, then update the focused tests and evidence notes around that contract.
+I’m writing the new recipe-identity module first so the rest of the patch can consume one cohesive source of truth instead of scattering hashes and dtype rules across node and tracker code. After that I’ll wire it into the proof, admission, and registration paths.
+The proof object now has the richer identity shape. I’m wiring the node admission gate to require the exact compatibility fingerprint, not just the older model/shard/recipe tuple, so a recipe or cache-layout drift fails closed before registration.
+I’ve got the proof object and node admission using the new fingerprint. The next step is to make the tracker see the same declared fingerprint at registration time so it can keep unsupported recipes dark instead of treating the proof as self-contained.

+The tracker parser is now expecting the runtime recipe to carry its own fingerprint, so I’m making that fingerprint part of the runtime-recipe object itself instead of only a report-side property. That keeps the wire shape self-describing and lets the tracker compare the exact cached proof.

+I’m updating the focused tests now. The old identity assertions assumed a much smaller report shape, so I’m making the test fixtures produce the new nested artifact/runtime-recipe fields and matching compatibility fingerprints instead of loosening the assertions.

+I caught a subtle mismatch before running tests: the report fingerprint includes the model config fingerprint, so the admission-side expected fingerprint has to include the same value. I’m fixing that now so the node and tracker compute the exact same digest rather than two almost-identical ones.
+I’m tightening one last edge: the declared compatibility fingerprint should be a real string, not an empty placeholder, otherwise a malformed registration could slide through as “unset.” That keeps the tracker fail-closed on the new field too.
+I’m aligning one more field before verification: on GPU hosts the node report includes the actual device name, so the admission-side expected fingerprint has to include the same value or it will diverge. I’m adding the same device-name derivation here rather than assuming CPU-only behavior.

+Another mismatch surfaced while comparing the proof hash: the report fingerprint also includes the runtime versions map, so the test seam has to populate that instead of leaving it empty. I’m fixing the test helper now so the node-side admission and tracker-side checks see the same runtime evidence.
+I’m adding one final self-consistency check on the node-side report parser: if a serialized capability report carries a top-level compatibility fingerprint, we should verify it matches the nested fields instead of trusting the wrapper blindly. That keeps the report object fail-closed even before admission runs.

+I’m normalizing one field that could have leaked a machine-local path into the fingerprint: tokenizer revision should be stable across nodes, so I’m preferring the model revision or model id instead of `name_or_path`. That keeps the fingerprint routable rather than host-specific.

+Implemented exact artifact/runtime recipe identity and fail-closed admission for DGR-003.
+
+- Added `packages/node/meshnet_node/runtime_recipe.py` with `ArtifactIdentity`, `RuntimeRecipeIdentity`, stable fingerprint helpers, and exact artifact binding.
+- Plumbed `compatibility_fingerprint` through node capability reports, doctor/startup, tracker capability state, and tracker registration storage.
+- Made admission fail closed on compatibility mismatches, including artifact, tokenizer, architecture, boundary schema, activation recipe, and cache layout drift.
+- Kept the test helper aligned with production defaults so the same fingerprint is emitted and checked end to end.
+- Wrote evidence at [`.scratch/distributed-gguf-runtime/evidence/DGR-003/README.md`](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.scratch/distributed-gguf-runtime/evidence/DGR-003/README.md), updated progress at [`.ralph-tui/progress.md`](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.ralph-tui/progress.md), and marked the story done in [the issue file](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.scratch/distributed-gguf-runtime/issues/03-define-exact-artifact-and-runtime-recipe-identity.md).

+--- RAW OUTPUT ---
+I’m reading the story, the rollout context, and the dependency evidence first so I can verify the exact build boundary before touching code. After that I’ll map the existing llama.cpp integration, then implement the pin/patch/build flow and run the focused checks.
+[shell] $ /bin/bash -lc "pwd && rg --files .claude .scratch .ralph-tui | sed -n '1,120p'"
+I hit an empty file listing from the first pass, so I’m switching to direct path reads for the specific context files the story requires. Next I’ll extract the pinned dependency evidence and the current implementation shape.

+I have the governing context and the story now. Next I’m checking the dependency evidence and the live repo state so I can distinguish required work from anything already in place.

+[shell] $ /bin/bash -lc "sed -n '1,260p' .scratch/distributed-gguf-runtime/architecture.md"
+The architecture is clear: the pin/patch stack is a first-class boundary, not a side detail. I’m now reading the adjacent DGR-002/DGR-003 evidence and the live native layout so I don’t duplicate or contradict what’s already been established.

+[shell] $ /bin/bash -lc 'find packages/node/native -maxdepth 4 -type f | sort'
+The protocol work is already present; this story is about the source boundary around llama.cpp. I’m searching for any existing pinning strategy or upstream assumptions so I can extend that instead of inventing a second mechanism.

+[shell] $ /bin/bash -lc "sed -n '1,220p' docs/research/distributed-gguf-landscape.md"
+I’ve confirmed there isn’t already a pinned llama.cpp source bundle in the repo. I’m now checking whether there’s an existing donor patch set I should normalize into this tree so the new stack reflects the actual upstream seam instead of inventing a fresh one.
+[shell] $ /bin/bash -lc "sed -n '1,220p' docs/research/distributed-gguf-github-followup.md | sed -n '280,340p'...

+[shell] $ /bin/bash -lc "find . -path '*/patch*' -o -name '*.patch' -o -name '*llama*' | sed -n '1,240p'"
+I have enough context to start the implementation path: a reproducible pin manifest, a patch directory, a build/check script, and a small native smoke target. I’m moving to file changes now, keeping the existing DGR-002/DGR-003 work untouched and isolating only the DGR-004 boundary.
+I’m writing the DGR-004 scaffold now: pinned source metadata, a minimal llama.cpp patch stack, and a build/smoke path that can run against a local fake checkout for tests while still enforcing the exact pin in real use. After that I’ll run the focused checks and tighten anything the build exposes.
+The first pass is in place, and I’ve already spotted one likely build issue: the scaffold CMake file was using placeholder strings instead of the values passed from the build script. I’m correcting that and making the script patch a disposable worktree copy so repeated rebuilds stay clean.

+[shell] $ /bin/bash -lc "nl -ba packages/node/native/llama/patches/0001-add-meshnet-worker-scaffold.patch | se...
+The scaffold is ready enough for a real validation pass. I’m running the new build path against a fake pinned source tree first, then the focused pytest slice, and I’ll fix whatever the build reveals before touching the evidence or status files.
+[shell] $ /bin/bash -lc 'python -m compileall -q packages tests'
+[shell] $ /bin/bash -lc 'python -m pytest -q tests/test_llama_worker_build.py'
+[shell] $ /bin/bash -lc 'git diff --check'
+The new test skipped because it only looked at the ambient PATH. I’m checking the project venv for `cmake` so I can make the smoke test actually exercise the build instead of opting out.
+[shell] $ /bin/bash -lc 'test -x .venv/bin/git && echo yes || echo no'
+[shell] $ /bin/bash -lc 'test -x .venv/bin/cmake && echo yes || echo no'

+[shell] $ /bin/bash -lc 'which -a cmake || true'
+[shell] $ /bin/bash -lc "find /usr /opt /tmp -path '*/cmake' -type f 2>/dev/null | head"
+`cmake` is absent in this sandbox, so I’m checking for a direct C++ compiler. If one is present, I can still make the build smoke real by switching the scaffold to a plain compiler-driven build instead of a CMake-only path.
+[shell] $ /bin/bash -lc 'which g++ || which c++ || true'
+[shell] $ /bin/bash -lc 'which clang++ || true'
+`g++` is available, so I can make the smoke path genuinely compile instead of skipping on missing CMake. I’m switching the scaffold build to a direct compiler invocation and keeping the patch/application flow intact.
+The smoke path is now compiler-backed, so the test should exercise real native compilation in this sandbox. I’m rerunning the focused slice and then I’ll only adjust if the patch application or the generated header trips over the fake checkout.

+--- RAW OUTPUT ---
+I’m starting by reading the story context, progress log, and dependency evidence so I can verify whether this already exists and, if not, implement it without disturbing unrelated work. Then I’ll trace the exact GGUF ownership path and run the targeted checks before I touch the story issue status.

+[shell] $ /bin/bash -lc "sed -n '1,260p' .ralph-tui/progress.md"
+I’ve confirmed the story is still `ready-for-agent`, and the dependencies are DGR-003 and DGR-004. Next I’m verifying those handoffs, the live implementation seams, and the repository state so I can tell whether this is a true implement-or-fix pass versus an already-complete check.

+I’ve verified the dependency handoffs: DGR-003 and DGR-004 are both marked done, and both evidence files point to passing targeted checks with only the expected sandbox socket limitation on full-suite runs. I’m now checking whether DGR-005’s range-aware ownership is already present in the live code, because if it is, I’ll only verify and document it instead of rewriting it.

+[shell] $ /bin/bash -lc "find packages/node/meshnet_node -maxdepth 3 -type f | sort | sed -n '1,260p'"
+The live tree already has some range-selection machinery for SafeTensors, but I haven’t found a GGUF ownership implementation yet. I’m narrowing the search to the new native and node-side seams that DGR-005 would need, because if those files are still stubs I’ll implement the missing ownership logic there rather than duplicating the SafeTensors path.

+I’ve confirmed the codebase already has exact identity plumbing and protocol scaffolding, but the GGUF-specific ownership seam is still missing. The likely shape here is a small new ownership/introspection layer plus tests, not a broad rewrite of the runtime, so I’m inspecting the existing model backend and startup reporting path to place that seam where later DGR-006/DGR-008 stories can consume it cleanly.

+I’m at the edit point now. The first patch adds the dense-Llama GGUF ownership helpers and authoritative loaded-range inference; after that I’ll wire the node/report/admission paths to consume those values instead of trusting raw CLI range claims.
+The first new module is in place. The next patch hit a context mismatch because the capability module’s helper layout is slightly different than expected, so I’m re-reading the exact sections before patching the shard-ownership fields into the report schema.

+[shell] $ /bin/bash -lc "sed -n '490,640p' packages/node/meshnet_node/capability.py"
+The code paths are wired. I’m updating the tests next so they verify the new ownership semantics explicitly: the report schema now includes endpoint ownership, and the test helpers need to prove the report comes from the backend’s loaded range when the backend exposes one.

+I’ve got the live-reporting path updated; I’m adding a focused test file now so DGR-005 proves the actual dense-Llama GGUF selection rules directly instead of only via downstream report plumbing. That test file will also give us the synthetic memory-scaling evidence the story asks for.

+The full suite reproduces the expected sandbox limits: tracker/socket-backed tests fail with `PermissionError`, and the native protocol tests still trip the protobuf runtime/gencode version mismatch in this interpreter.

+I’ve got the evidence points I need, and I found one reusable pattern worth preserving: capability/proof paths need to be driven from the backend’s loaded range and ownership, not CLI selection. I’m adding that to the top of the progress log and appending the DGR-005 session note now.

+The reusable pattern is already visible in the progress log, but I’m adding one more specific rule from the ownership work and then I’ll write the DGR-005 handoff file with the exact validation matrix we actually ran.
+I’m making two small durable edits now: one reusable pattern at the top of the progress log, and the story issue status flip after the evidence file is in place.

+DGR-014 is blocked, not complete.
+
+What I verified:
+- `DGR-011` is still `passes: false` in `.scratch/distributed-gguf-runtime/prd.json`.
+- `DGR-011` is blocked on `DGR-010`, and `DGR-010` is blocked because there is still no certified dense-Llama artifact on mounted storage.
+- Current mounted model storage still shows Qwen artifacts and llama.cpp vocab files, not the certified dense-Llama GGUF/safetensors pair needed for the comparison.
+
+What I changed:
+- Added `.scratch/distributed-gguf-runtime/evidence/DGR-014/BLOCKED.md`
+- Appended the iteration note to `.ralph-tui/progress.md`
+
+What I did not change:
+- I did not update the issue to `Status: done`.
+- I did not touch the existing unrelated worktree changes.
+
+Checks:
+- `git diff --check` passed.
+
+The blocker to unblock this story is either:
+1. complete `DGR-010` and `DGR-011` with a certified dense-Llama artifact mounted on the configured drive, then rerun the release gate, or
+2. provide the exact certified artifact and route evidence needed for the comparable safetensors vs GGUF run.

+Blocked. DGR-015 cannot be certified in this workspace because its prerequisite `DGR-014` is still not passed, and `DGR-014` is blocked on the missing certified dense-Llama artifact.
+
+What I did:
+- Verified the dependency chain in `.scratch/distributed-gguf-runtime/prd.json`.
+- Confirmed `packages/node/meshnet_node/boundary_adapter.py` still fails closed for `qwen3` / `qwen3-moe`, so there is no certified Qwen3 adapter yet.
+- Wrote a durable blocker handoff at [`.scratch/distributed-gguf-runtime/evidence/DGR-015/BLOCKED.md`](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.scratch/distributed-gguf-runtime/evidence/DGR-015/BLOCKED.md).
+
+Why it is blocked:
+- `DGR-014` is still `passes: false`.
+- `DGR-014` depends on `DGR-011`, which is blocked by the missing certified dense-Llama artifact needed for the real release-gate comparison.
+- Real consumer-hardware Qwen3 acceptance cannot be run here without that prerequisite chain.
+
+No code was changed beyond the blocker note, and no certification tests were run because the story cannot be completed yet.

+--- RAW OUTPUT ---
+I’m reading the story context, progress log, and dependency evidence first so I can keep the patch scoped to DGR-016 and avoid touching unrelated work. After that I’ll verify the current tree state, then implement only the upstream package artifacts and tests that belong to this story.

+The story is blocked on a prerequisite that has no pass evidence yet, but I can still package the upstream-facing proposal from the existing research and tests.

+The focused suite found environment-sensitive errors instead of a clean pass, so I’m pulling the failure detail before I decide whether to keep the package as a partially verified handoff or fix anything locally.

+I’m recording the iteration in the Ralph progress log now. I’m keeping it honest: package drafted, a useful subset of tests passed, and the remaining failures are prerequisite/environment blockers rather than something I introduced.

+- I assembled the DGR-016 package in [evidence README](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.scratch/distributed-gguf-runtime/evidence/DGR-016/README.md#L1), [API note](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.scratch/distributed-gguf-runtime/evidence/DGR-016/api-note.md#L1), and [outreach draft](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.scratch/distributed-gguf-runtime/evidence/DGR-016/outreach.md#L1).
+- I also updated [progress.md](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.ralph-tui/progress.md#L10) with a reusable pattern and logged the iteration at [its DGR-016 entry](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.ralph-tui/progress.md#L14).
+
+Verification:
+- Package-relevant pytest subset passed: `50 passed in 0.90s`.
+- Broader focused pytest slice did not go cleanly: `58 passed, 1 skipped, 9 failed, 12 errors`.
+- The two reported blockers were pre-existing environment issues, not the new docs:
+  - protobuf gencode/runtime mismatch in `tests/test_native_shard_protocol.py`
+  - sandbox socket `PermissionError` in `tests/test_kv_cache_distributed.py`
+- `python -m compileall -q packages tests` passed.
+- `git diff --check` passed.
+
+Blocker:
+- I did not mark DGR-016 done because the dependency story is still blocked in [DGR-010 BLOCKED.md](/run/media/popov/d/DEV/repos/d-popov.com/AI/.claude/worktrees/distributed-gguf-runtime/.scratch/distributed-gguf-runtime/evidence/DGR-010/BLOCKED.md#L1), so the package is partial rather than release-ready.
+- If you want, the next useful step is either to tighten the outreach package further or to work the DGR-010 unblock path.

Use `graphify path "<A>" "<B>"` for relationships and `graphify explain "<concept>"` for focused concepts. These return a scoped subgraph, usually much smaller than GRAPH_REPORT.md or raw grep output.

+# Distributed GGUF Runtime — Project Milestone Map
+
+## What this project is
+
+We're building a system to run a giant AI model (DeepSeek V4 Flash, 671B params) split across multiple machines. Instead of one machine needing one huge GPU, we chop the model's layer stack into ranges (shards), run each range on a different machine, and pipe data between them over the network.
+
+Key components: **Tracker** (matchmaker that assigns shards to machines), **Nodes** (worker machines running a shard), **Gateway** (entry point that receives user requests and routes them through shards), all built on top of **llama.cpp** (the C++ engine that actually runs the model).
+
+## Where we are (July 22, 2026)
+
+**13 of 55 tasks complete.** M1 is 90% done — the protocol, build system, and scaffolding are in place. The next 4 tasks finish M1, then M2 begins the real engine work.
+
+## Milestone structure

+## Remaining tasks by milestone
+
+### M1: Protocol & Build System (4 remaining)

+
+## Current state
+
+- **Branch:** `ralph/distributed-gguf-runtime`
+- **Progress:** 13/55 tasks complete, 42 remaining
+- **Next task:** DGR-030 (build presets + CI matrix)
+- **Last session stopped:** Ralph hit Claude session limit at 09:44 on July 22. Reset at 13:30 Europe/Sofia. Use `ralph-tui resume` to continue.
+- **26 files committed** from the last Ralph run (DGR-019..029 work). Branch pushed to origin.
+
+## Working conventions
+
+- Ralph runs headless: reads backlog, spawns fresh Claude Code per ticket, verifies, reports
+- DGR-019/020 marked `ready-for-human` — needs review before certifying
+- Changes left uncommitted for review per Ralph policy (unless explicitly pushed)
+- `ralph-tui resume` picks up where it left off

+"""The locked DGR-019 alpha/beta performance contract.
+
+Four benchmark lanes feed the DeepSeek V4 Flash release gates: controlled
+safetensors, whole-model GGUF, dense distributed GGUF, and V4 Flash
+distributed. The first two are already locked by DGR-001
+(:mod:`meshnet_node.performance_contract`); this module locks the other two,
+plus the alpha (DGR-054) and beta (DGR-070) gate thresholds that read them
+back.
+
+The contract is written down *before* any distributed implementation
+produces a number (DGR-019), so ``contract_sha256`` is verified the same way
+:mod:`meshnet_node.glm_alpha.contract` verifies its own alpha contract: the
+document's canonical content is re-hashed on every load and compared against
+a digest pinned independently in code. A hand-edited "the threshold was
+always 5%" mutation is rejected, not silently trusted. An amendment requires
+a new ``contract_id``/``contract_version`` under human review; the superseded
+contract is retained.
+
+Alpha's useful-speed threshold carries one additional property no other
+threshold here has: ``human_approval``. The numeric ratios are locked now,
+but DGR-054 (the alpha gate) may not treat useful-speed as satisfied on the
+ratio alone — a human must approve the observed ratio against real evidence.
+That is a property of *how the threshold may be used*, not a weaker
+threshold, and it is asserted structurally by :func:`parse_contract`.

+"""Exact split-GGUF artifact manifest (DGR-026).
+
+A split-GGUF artifact is only as trustworthy as its binding to the whole-model
+artifact it was cut from. This module defines the manifest that makes a set of
+split files an *exact*, checkable artifact rather than a pile of files someone
+happened to name plausibly: it pins the source artifact's own content hash, the
+tokenizer/revision the splits were tokenized against, and — per split — the
+exact file name, size, cryptographic hash, and its range/role within the
+source.
+
+Quantization and split topology (how many splits, which layers each one
+covers) are recipe inputs recorded on the manifest, never constants in this
+module. A manifest with two splits and one with twenty are both valid; nothing
+here assumes a stage count or a fixed layer range. Provisioning
+(:mod:`meshnet_node.split_gguf.provision`) consumes whatever this manifest
+declares.
+
+This module mirrors two existing conventions rather than inventing new ones:
+the DGR-017 pinned-shard manifest shape (`meshnet_node.glm_alpha.manifest`) for
+per-file identity records, and the DGR-003 `DerivativeBinding` range/source
+convention (`meshnet_node.runtime_recipe`) for binding a split to its source by
+digest and half-open layer range.

+continuing from it — and a partial is promoted to its final name only after its

@@ -6,14 +6,57 @@ updating the recorded tree/blob assumptions and reviewing every patch anew.
 
 ## Ordered series
 
+One numbered patch per concern (ADR-0024 local seams only):
+
 1. `0001-cmake-reserve-meshnet-patch-stack-abi-marker.patch` adds only an
    interface-library marker used to prove the patched source was configured.
    It has no execution, transport, model-loading, or semantic effect.
+2. `0002-dense-llama-owned-range-loading.patch` (range loading) adds the
+   `meshnet_owned_layer_start/end` model params, validates the half-open range
+   against the GGUF block count for dense Llama only, filters per-layer tensor
+   registration and the optional scale pass to the owned range, and keeps
+   endpoint tensors with their owning endpoints. Zero/zero params preserve
+   stock whole-model loading.
+3. `0003-owned-range-filtered-state-report.patch` (filtered state) adds
+   `llama_meshnet_range_report` and populates it from registered tensors and
+   backend buffers — derived, never caller-asserted. Layer-filtered KV and
+   session-to-sequence mapping remain later scoped stories (DGR-038).
+4. `0004-dense-boundary-io-endpoint-guard.patch` (boundary I/O) extends the
+   report with endpoint ownership flags and fails the dense-Llama graph closed
+   for any partial owned range until typed head/tail endpoint adapters carry
+   the architecture boundary I/O (DGR-035).
+5. `0005-worker-range-report-hook.patch` (worker hooks) exposes the
+   `llama_model_meshnet_range_report` C API the project-owned worker binds to
+   and registers a model-free native fixture test for it.
 
-Future patches may implement only the ADR-0020 local seams: range-aware tensor
-loading, endpoint ownership, architecture-defined intermediate boundaries, and
-layer-filtered KV/session mapping. Meshnet routing, Tracker, gRPC, relay,
-billing, authentication, and telemetry must remain outside this directory.
+Meshnet routing, Tracker, gRPC, relay, billing, authentication, and telemetry
+remain outside this directory; the stack is checked for such control-plane
+code and for license/attribution preservation on every apply.
+
+## Upstream assumptions and fail-closed verification
+
+`patches/UPSTREAM-ASSUMPTIONS.json` records, for every patch, the exact
+upstream blob IDs each touched file must have before and after the patch, plus
+the upstream file/API assumptions the patch relies on.
+`scripts/llama_cpp_dependency.py verify` runs the deterministic cycle against
+the exact manifest pin:
+
+1. Verify the materialized checkout identity (commit, tree, blobs, license,
+   cleanliness) exactly like `fetch`.
+2. For each patch in `patches/series` order, check the recorded pre-image
+   blobs of the files it touches, then `git apply --check`, then
+   `git apply --index`. The first patch whose assumptions or context fail is
+   reported as the first incompatible patch and nothing further is attempted.
+3. Verify the patched tree equals the manifest `patched_tree` and touches
+   exactly the manifest `patched_paths`.
+4. Reverse the series in reverse order (`git apply -R --index`) and verify the
+   restored tree equals the pristine locked tree, leaving the checkout
+   pristine.
+
+`apply` performs steps 1–3 and leaves the stack applied for a native build;
+`reverse` performs step 4 on an applied checkout. A pin change that breaks any
+patch therefore fails loudly with the first incompatible patch instead of
+silently drifting.
 
 `scripts/llama_cpp_dependency.py fetch` reads the in-repo manifest and checks out
 only its exact commit as detached HEAD in `build/llama.cpp/source`, an ignored

+Concern: range loading. Adds meshnet_owned_layer_start/end model params,
+validates the half-open range against the GGUF block count for dense Llama

+pass to the owned range, and keeps endpoint tensors with their owning
+endpoints (head: token embeddings; tail: final norm and output head).
+Stock zero/zero params preserve whole-model loading.

+From: Meshnet <meshnet@invalid>
+Subject: [PATCH] llama: expose worker-owned range report hook and fixture
+
+Concern: worker hooks. Exposes the llama_model_meshnet_range_report C API the
+project-owned worker binds to and registers a model-free native fixture that
+loads tiny generated GGUF ranges and asserts ownership, endpoint, and
+byte-report invariants.
