+
+# /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()},

+}

+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. Workers must reject incompatible protocol versions and resource demands before allocating large buffers. 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. Benchmarks compare the same prompts, output lengths, sampling policy, device, and concurrency, and they separate near-lossless quality checks from quantized speed and fit claims.

+`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

+# 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-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`.
+

+| `python3 -m compileall -q packages tests` | exit 0 |
+| `git diff --check` | exit 0 (no output) |
+
+## 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

+- `scripts/llama_cpp_dependency.py`
+- `tests/test_llama_cpp_dependency.py`

+- `.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).

+When the user types `/graphify`, use the installed graphify skill or instructions before doing anything else.
+
+Rules:
+- For codebase questions, first run `graphify query "<question>"` when graphify-out/graph.json exists. 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.
+- Dirty graphify-out/ files are expected after hooks or incremental updates; dirty graph files are not a reason to skip graphify. Only skip graphify if the task is about stale or incorrect graph output, or the user explicitly says not to use it.
+- If graphify-out/wiki/index.md exists, use it for broad navigation instead of raw source browsing.
+- Read graphify-out/GRAPH_REPORT.md only for broad architecture review or when query/path/explain do not surface enough context.
+- After modifying code, run `graphify update .` to keep the graph current (AST-only, no API cost).

+# 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
+
+```
+M1: Build system + protocol (DGR-021..033)
+  └─► M2: Real shard engine + network wiring (DGR-034..043)
+          └─► M3: DeepSeek V4 Flash integration (DGR-044..054)
+                  └─► M4: Hardening, batching, performance (DGR-055..067)
+                          └─► M5: Release + upstream (DGR-068..071)
+```
+
+## Completed tasks (13/55)
+
+### M0 — Foundation & Cleanup (DGR-017..020)
+- **DGR-017** — Reconcile superseded backlog (clean slate)
+- **DGR-018** — Define canonical Ralph/Gitea metadata schema
+- **DGR-019** — Lock alpha/beta performance contracts *(needs human review)*
+- **DGR-020** — Run controlled whole-model GGUF baseline *(needs human review)*
+
+### M1 — Protocol & Build System (DGR-021..029)
+- **DGR-021** — Define versioned named-tensor stream envelope
+- **DGR-022** — Define Shard lifecycle and structured status RPCs
+- **DGR-023** — Make Python and C++ protobuf generation reproducible
+- **DGR-024** — Implement real generated-gRPC protocol harness
+- **DGR-025** — Define exact artifact/runtime recipe identity
+- **DGR-026** — Provision exact split-GGUF artifacts outside /home
+- **DGR-027** — Add exact llama.cpp provenance manifest + fetch workspace
+- **DGR-028** — Implement numbered patch-stack apply and verification
+- **DGR-029** — Create native CMake skeleton + deterministic CPU lane
+
+## Remaining tasks by milestone
+
+### M1: Protocol & Build System (4 remaining)
+
+| Task | What it means |
+|------|---------------|
+| **DGR-030** | Build presets + CI matrix — make the C++ build work with CUDA/ROCm/CPU, add CI tests |
+| **DGR-031** | ShardEngine interface — define the contract every shard must implement |
+| **DGR-032** | Fake ShardEngine — a pretend shard that returns correct-shaped fake data for testing |
+| **DGR-033** | Fake C++ gRPC worker — wrap that fake shard in a real gRPC server (first end-to-end network test) |
+
+### M2: Shard Engine & Native Worker (DGR-034..043)
+
+| Task | What it means |
+|------|---------------|
+| **DGR-034** | Range-aware GGUF ownership — teach the shard to load only its slice of layers |
+| **DGR-035** | Boundary I/O — define exact tensor shapes crossing between shards |
+| **DGR-036** | Fixture vs real-model parity — prove fake shard matches real shard outputs |
+| **DGR-037** | Bind llama.cpp to the worker — plug real llama.cpp engine into gRPC worker |
+| **DGR-038** | Hot KV State — keep each shard's piece of conversation memory hot and accessible |
+| **DGR-039** | Two-process acceptance — run 2 shards on one machine, verify output matches whole model |
+| **DGR-040** | Worker supervision — start/monitor/restart native workers (like container orchestrator for shards) |
+| **DGR-041** | Register capabilities — tell the Tracker "I can run layers 10-20 on this GPU" |
+| **DGR-042** | Carry frames through seams — tensor data travels over direct connections and relay |
+| **DGR-043** | Cost inputs to routing — tell Tracker "this shard takes X ms per token, Y GB bandwidth" |
+
+### M3: DeepSeek V4 Flash Integration (DGR-044..054)
+
+| Task | What it means |
+|------|---------------|
+| **DGR-044** | Pin the target contract — document exactly what V4 Flash needs (layers, tensors, memory) |
+| **DGR-045** | Inventory V4 tensors — open the model file, list every tensor, assign to layers |
+| **DGR-046** | V4 architecture boundary — define data crossing shard boundaries for MoE model |
+| **DGR-047** | Adapt V4 for ranged ownership — modify upstream code so each machine runs only its range |
+| **DGR-048** | Token-ID sideband — pass token ID alongside data between shards for expert routing |
+| **DGR-049** | Shard-local attention state — keep attention/auxiliary state local per shard |
+| **DGR-050** | Validate MoE routing — verify expert routing works when experts are on different machines |
+| **DGR-051** | V4 ShardEngine adapter — the big integration: make V4 fit into the ShardEngine interface |
+| **DGR-052** | V4 local vs distributed parity — run V4 on one machine vs split across two, verify same output |
+| **DGR-053** | Certify real 2-4 stage route — run V4 across 2-4 machines with real GPUs *(human review)* |
+| **DGR-054** | Enforce V4 alpha gate — alpha-quality checkpoint *(human review)* |
+
+### M4: Hardening & Performance (DGR-055..067)
+
+| Task | What it means |
+|------|---------------|
+| **DGR-055** | Continuous batching — handle multiple user requests simultaneously |
+| **DGR-056** | Admission and backpressure — don't pile up requests, slow down gracefully |
+| **DGR-057** | Benchmark batching — measure max simultaneous users before slowdown |
+| **DGR-058** | Failure hardening — handle shard crashes mid-request gracefully |
+| **DGR-059** | Route recovery — reroute around dead shards automatically |
+| **DGR-060** | Long-context correctness — verify distributed version handles 128K token conversations |
+| **DGR-061** | 10+ stage routing — test routing across 10+ machines |
+| **DGR-062** | Dynamic 10+ stage V4 scenario — real-world test across 10+ machines *(human review)* |
+| **DGR-063** | Profile and optimize — find and fix the slowest part of the pipeline |
+| **DGR-064** | Activation compression — compress data between machines to save bandwidth |
+| **DGR-065** | MTP ownership — define multi-token prediction across shards |
+| **DGR-066** | Implement MTP — build and benchmark distributed multi-token prediction |
+| **DGR-067** | Certify capability matrix — final: what hardware, what models, what performance *(human review)* |
+
+### M5: Release & Upstream (DGR-068..071)
+
+| Task | What it means |
+|------|---------------|
+| **DGR-068** | Package releases — reproducible release binaries for others to install |
+| **DGR-069** | Upstream patches — clean patches to submit to llama.cpp project *(human review)* |
+| **DGR-070** | Beta gate certification — final beta-quality checkpoint *(human review)* |
+| **DGR-071** | Maintenance docs — playbook for updating pin, reapplying patches, certifying releases |
+
+## 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

+  _High betweenness centrality (0.186) - this node is a cross-community bridge._
+- **Are the 18 inferred relationships involving `_TrackerHandler` (e.g. with `AccountStore` and `BillingLedger`) actually correct?**

+"""The locked DGR-019 alpha/beta performance contract.

+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

+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.

+Model artifacts must use configured mounted-drive storage and never `/home`

+Provisioning never trusts a partially-downloaded file. Each split is staged as

+already on disk — a `SplitFetcher` is handed that offset and is responsible for
+continuing from it — and a partial is promoted to its final name only after its
+SHA-256 matches the manifest exactly. A short, truncated, or hash-mismatched
