# DGR-018 evidence — canonical Ralph and Gitea metadata schema
**Completed:** 2026-07-16
**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
Make `prd.json` the validated source from which Markdown (and, later, Gitea) issues
can be generated losslessly, per
`.scratch/distributed-gguf-runtime/issues/018-define-canonical-ralph-and-gitea-metadata-schema.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 `369b207`), 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, while `userStories` itself was byte-identical to `HEAD`. This looked like an abandoned,
uncommitted partial edit from a prior session, not intentional current work — those fields are
exactly the schema/quality-gate/audit-provenance content this story depends on, and their loss
wasn't explained by any acceptance criterion. They were restored (see "Changes" below) rather than
silently accepted or discarded, per the instruction to investigate unexplained working-tree state
before building on top of it.
## Changes
### `scripts/ralph_prd_schema.py` (new)
Single module providing:
- **Parse:** `load_prd(path)` — JSON load with clear `PrdValidationError`s for missing file /
invalid JSON / non-object document.
- **Canonical schema registry:** `STORY_FIELDS` (name → required/type), `EXECUTION_MODES`,
`EVIDENCE_CLASSES`, `HARDWARE_FLAGS`, `UPSTREAM_FLAGS`, `TRIAGE_VALUES`. Covers every field named
in the acceptance criteria: stable `id`/`title`, `labels`, `milestone`, derived `type`
(`derive_type`), `dependsOn`, derived `blocks`, `triage`, `evidenceClass`, and
`hardware`/`model`/`upstream` flags.
- **Structural validation:** `validate_schema(data)` — required fields, types, enum membership,
ID convention, `type:`/`priority:` label cardinality, non-empty `acceptanceCriteria`.
- **Semantic validation:** `validate_semantics(data)` — unique IDs, unique titles, `dependsOn`
resolves to known stories (no self-dependency), dependency graph is acyclic (with a reported
cycle path on failure), `blocks` matches the dependency graph exactly (sorted set equality, not
superset), and `evidencePath` matches the per-story convention.
- **Fresh vs. in-progress backlog:** `validate_fresh_backlog(data)` additionally requires every
story to start `passes: false` (for a backlog that hasn't started execution yet);
`validate_backlog(data)` is the composed check for a real, in-flight backlog where some stories
have legitimately completed.
- **Self-consistency check:** `validate_metadata_schema_consistency(data)` — when prd.json declares
its own `metadataSchema`/`qualityGates` (as this one now does), verifies that self-documentation
hasn't drifted from what the validator actually enforces (enum sets, required/optional field
lists, presence of `qualityGates` and `generatedArtifactDisclaimer`). This is a no-op for minimal
fixture PRDs that don't carry that documentation.
- **Generation (one-directional, prd.json → artifact):** `render_issue_markdown(story, data)`
renders the exact Markdown convention already used by
`.scratch/distributed-gguf-runtime/issues/*.md`, sourcing the "Shared quality gates" bullets from
`data["qualityGates"]` and the leading disclaimer from
`data["metadataSchema"]["generatedArtifactDisclaimer"]` (falling back to a module default only
when `data` omits them) — not from a duplicated Python string literal.
`to_gitea_issue_payload(story, data)` wraps the same body into a Gitea create-issue-shaped payload
(`title`, `body`, `labels`, `milestone`).
- **Authority guard:** `check_generated_markdown_authority(text, disclaimer=...)` rejects generated
Markdown that's missing the disclaimer or that contains a conflicting authority claim (e.g. "this
file is authoritative"). There is deliberately no Markdown → prd.json parser, so a generated
artifact structurally cannot feed `passes` (or anything else) back into the authoritative source.
- CLI: `python scripts/ralph_prd_schema.py validate <prd.json> [--fresh]` and
`... render <prd.json> <STORY-ID>`.
### `.scratch/distributed-gguf-runtime/prd.json`
- Restored the top-level `sourceOfTruth`, `qualityGates`, `milestones`, and `supersededStories`
objects to their `HEAD` content (see "Pre-existing state" above); `userStories` was already
identical to `HEAD` and is unchanged in content.
- Extended `metadataSchema` (previously incomplete for this story's own acceptance criteria) with:
`requiredStoryFields` now also lists `notes` and `blocks` (present on all 55 stories); new
`optionalStoryFields: ["completionNotes"]`; new `hardwareValues`/`upstreamValues` enums (`model`
is documented as an open convention, not a closed enum, since quantization/model targets are
dynamic recipe inputs per `RALPH-CONTEXT.md`); new `typeDerivation` and `labelConventions`
(reserved prefixes, cardinality); new `generatedArtifactDisclaimer` (the exact string generated
artifacts must start with); extended `dependencyRules`/`authorityRule` prose to match what the
validator enforces.
- Reworded `sourceOfTruth`'s stale "All stories are unimplemented ... passes=false" clause, which
was no longer accurate once DGR-017 completed.
- Marked `DGR-018.passes = true` with `completionNotes` recording this story's outcome.
### `.scratch/distributed-gguf-runtime/issues/018-define-canonical-ralph-and-gitea-metadata-schema.md`
Regenerated via `render_issue_markdown` to reflect `passes: true` (checked acceptance criteria,
"completed" status line, "Verified evidence" handoff line) — matching the same convention DGR-017's
issue file already used for a completed story.
### `tests/test_ralph_prd_schema.py` (new)
108 deterministic, model-download-free, GPU-free tests:
- **Parse** (4 tests): real backlog parses to 55 stories; missing file, invalid JSON, and
non-object documents raise `PrdValidationError`.
- **Structural/semantic validation against the real backlog** (7 tests): passes `validate_schema`,
`validate_semantics`, and the composed `validate_backlog`; unique IDs/titles; all `dependsOn`
resolve; `blocks` matches the derived dependency graph for all 55 stories; no cycle; every
`passes: true` story carries `completionNotes` and an existing evidence README (a durable
invariant, not a hardcoded list of which stories have completed — that list will keep growing).
- **Structural/semantic failure-mode fixtures** (13 tests): missing required field, bad enum, wrong
type, empty `acceptanceCriteria`, multiple `type:` labels, duplicate ID, duplicate title, unknown
dependency, self-dependency, dependency cycle, mismatched `blocks`, bad `evidencePath`.
- **Fresh-backlog invariant** (3 tests): accepts all-`false`, rejects a premature `passes: true`,
and confirms `validate_backlog` (the in-progress variant) permits completed stories.
- **prd.json-as-source-of-truth for boilerplate** (9 tests): `qualityGates`/`metadataSchema`
self-consistency checks (no-op without them, catches a drifted enum, catches a missing
`qualityGates`), `quality_gate_bullets` flattening order, `authority_disclaimer` precedence and
fallback, and 3 tests asserting the real backlog's declared schema matches the code, its 7
quality-gate bullets are intact, and its disclaimer matches the module default.
- **`derive_type`** (4 tests): label-derived type, release-gate synthetic type for HITL gate
stories, `None` when absent, and confirmation that the real backlog's two release-gate stories
(`DGR-054`, `DGR-070`) derive `release-gate`.
- **Markdown generation round trips** (55 parametrized + 6 tests): `render_issue_markdown` for
every story `DGR-017`..`DGR-071` is byte-for-byte identical to the corresponding file already in
`.scratch/distributed-gguf-runtime/issues/`; determinism; leading disclaimer; `Blocks (derived)`
rendering (`None` vs. listed); checkbox reflects `passes`; filename convention.
- **Authority-claim rejection** (4 tests): accepts real generated text, rejects a missing
disclaimer, rejects an overriding claim, and confirms every committed issue file in
`.scratch/distributed-gguf-runtime/issues/` passes the check.
- **Gitea payload generation** (3 tests): payload shape, body carries no information beyond what's
in prd.json, and every real story's payload is well-formed and authority-clean.
## Commands and results
```bash
python3 -m pytest -q tests/test_ralph_prd_schema.py
```
```text
108 passed in 0.16s
```
```bash
python3 -m compileall -q packages tests
```
Exit code 0, no output (all files compile).
```bash
git diff --check
```
Exit code 0 (no whitespace errors).
```bash
python3 scripts/ralph_prd_schema.py validate .scratch/distributed-gguf-runtime/prd.json
```
```text
OK: 55 stories validated.
```
```bash
python3 scripts/ralph_prd_schema.py validate .scratch/distributed-gguf-runtime/prd.json --fresh
```
```text
ERROR: DGR-017: fresh backlog requires passes=false, got True
ERROR: DGR-018: fresh backlog requires passes=false, got True
2 validation error(s).
```
Expected: `--fresh` is the invariant for a backlog that hasn't started execution; this backlog has
legitimately completed two stories, so it correctly fails that stricter check while passing the
plain (in-progress) `validate` command above.
### Baseline: full repository suite (ad hoc `python3`, not a project venv)
```bash
python3 -m pytest -q
```
```text
20 failed, 776 passed, 13 skipped, 2 warnings in 244.17s (0:04:04)
```
None of the failures touch `scripts/ralph_prd_schema.py` or `tests/test_ralph_prd_schema.py`
(neither file existed before this story; this story adds no changes to `packages/`). Four of the
20 failures reproduce exactly the pre-existing baseline defects DGR-017's evidence already recorded
(`test_tracker_models_endpoint_lists_registered_hf_repo_and_short_name_alias`,
`test_torch_node_applies_tracker_load_shard_directive`,
`test_shard_heal_cycle_surviving_node_covers_dead_peers_gap`,
`test_a_node_with_an_unusable_precision_covers_no_layers`). The remaining 16 (activation
compression, dynamic routing, gossip/relay, manual route benchmark, openai gateway, TOPLoC
calibration dispatch, tracker control plane) include a `ModuleNotFoundError: langchain` failure,
indicating this ad hoc `python3` lacks the project's `dev` extras (`langchain-openai`, etc.) rather
than a real regression; this environment has no project virtualenv (e.g. no `.venv-rocm`) to run
against instead. Not investigated further as out of scope for this story.
## Limitations
- No real Gitea instance or API integration exists; `to_gitea_issue_payload` defines the payload
shape (title/body/labels/milestone) only. Creating issues against a live Gitea server is future
work, not claimed here.
- `model` is intentionally validated as an open string, not a closed enum, per
`RALPH-CONTEXT.md`'s "Quantization and placement are dynamic recipe inputs" constraint; the schema
documents (`metadataSchema.modelConvention`) but does not restrict its value set.
- Validation and generation were exercised only against this feature's `prd.json`
(`.scratch/distributed-gguf-runtime/prd.json`); `docs/prd.json` and other `.scratch/*/prd.json`
files in this repo use a materially different (simpler) shape and are out of scope.
## Dependency handoff
DGR-021 and DGR-025 (this story's derived `blocks`) may treat `prd.json`'s `metadataSchema`,
`qualityGates`, and this validator/generator as stable. Any future field addition to a story shape
must extend `STORY_FIELDS` in `scripts/ralph_prd_schema.py` and the corresponding
`metadataSchema.requiredStoryFields`/`optionalStoryFields` in `prd.json` together —
`validate_metadata_schema_consistency` fails closed if they drift apart.

"""Canonical schema, validator, and generator for Ralph `prd.json` backlogs.
`prd.json` is the single authoritative source for a Ralph-managed backlog.
This module defines the field shape every story must have, validates
structural and cross-story invariants (unique IDs/titles, resolvable
`dependsOn`, acyclic dependency graph, `blocks` derived correctly), and
renders the same fields into the generated Markdown/Gitea-issue view used
by `.scratch/<feature>/issues/*.md`.
Generation is one-directional: prd.json -> Markdown / Gitea payload. There
is no Markdown -> prd.json parser, so a generated artifact can never feed
`passes` (or any other field) back into the authoritative source. Every
generated Markdown document must start with the authority disclaimer
(`authority_disclaimer()`, sourced from prd.json's own `metadataSchema` when
present) so a stray edit of the generated file cannot be mistaken for a
source-of-truth change. The shared "quality gates" boilerplate is likewise
sourced from prd.json's `qualityGates`, not duplicated as a Python literal.

python scripts/ralph_prd_schema.py validate .scratch/distributed-gguf-runtime/prd.json
python scripts/ralph_prd_schema.py render .scratch/distributed-gguf-runtime/prd.json DGR-018
