feat: add canonical schema proof artifacts and emitted-shape fixtures#38
Conversation
…tes, schema descriptions
- Add ErrUnknownPath sentinel error to ValidateContent so callers can
distinguish "not validated" from "valid" via errors.Is
- Add description fields to author and state properties in issue.schema.json
- Add path migration note in schemas/README.md for old {number}.json path
- Fix stale doc states: remediation boundary/checklist marked Complete,
emitted-shape boundary marked Implemented, all checklist boxes checked
- Add merge-approval note to emitted-shape review verdict
- Add TODO comments for compiler architecture improvements in validate.go

…criptions, doc states
- Add ErrUnknownPath sentinel error to ValidateContent() so callers can
distinguish "not validated" from "valid" via errors.Is
- Add description fields to author, state, labels, assignees properties
in issue.schema.json documenting casing conventions and flattening
- Add migration note in schemas/README.md for old {number}.json path
- Fix stale doc states: update "Proposed"/"Defined" to "Implemented"/"Complete"
- Check off completed checklist items in remediation and conformance docs
- Clarify emitted-shape review verdict as "approved for merge"
- Add TODO comments for compiler architecture nits (global compilerErr,
dual compiler path) to address when second schema is added

Sorry, something went wrong.

🟡 Spec document claims ValidateContent() returns nil for unknown paths, but code returns ErrUnknownPath
The proof-direction doc states ValidateContent() "Returns nil for unknown paths — unregistered paths pass silently." However, the actual implementation at internal/schema/validate.go:46-47 returns fmt.Errorf("%w: %s", ErrUnknownPath, path), and the test TestValidateContentUnknownPath at internal/schema/validate_test.go:128-135 explicitly asserts errors.Is(err, ErrUnknownPath). The authoritative boundary doc (docs/canonical-file-schema-ownership-boundary.md:119) was corrected to say ErrUnknownPath, but this file was missed. This same stale claim also appears in docs/first-canonical-schema-proof-boundary.md:92, docs/first-canonical-schema-proof-plan.md:132, and docs/first-canonical-schema-proof-checklist.md:67. Consumers coding against these specs would fail to handle ErrUnknownPath errors.

| 2. The validation utility is in `internal/schema/`, not in `internal/relayfile/`. It does not import `internal/relayfile/` types. | ||
| 3. Schema files are embedded via `schemas/embed.go` (`//go:embed README.md github/*.json`). No filesystem reads at runtime. | ||
| 4. Path pattern matching uses regex (`^/github/repos/[^/]+/[^/]+/issues/\d+/meta\.json$`). One pattern registered for this proof. | ||
| 5. `ValidateContent()` returns `nil` for paths with no registered schema. It does not reject unknown paths. |

🟡 Boundary Rule #5 states ValidateContent returns nil for unknown paths, contradicting implementation
Boundary Rule #5 states "ValidateContent() returns nil for paths with no registered schema. It does not reject unknown paths." This is a stated design constraint that the implementation is supposed to follow. The actual code at internal/schema/validate.go:46-47 returns ErrUnknownPath, and TestValidateContentUnknownPath at internal/schema/validate_test.go:128-135 asserts that ErrUnknownPath is returned. The rule is factually wrong — the implementation intentionally rejects unknown paths with a sentinel error.

| - **Caching**: `sync.Once` for initial compilation of all registered schemas; `sync.Map` for compiled schema cache. | ||
| - **Compiler config**: `jsonschema.Draft2020` default draft, `AssertFormat()` enabled (validates `date-time`, `uri`). | ||
| - **Error format**: `"validate <path> against <schema>: <detail>"` — includes VFS path, schema file, and JSON Schema validation detail. | ||
| - **Unknown paths**: `registeredSchema()` returns `""` -> `ValidateContent()` returns `nil`. |

🟡 Proof plan is internally inconsistent: code snippet says ErrUnknownPath but prose says nil
Within the same file, the code snippet at line 120-121 correctly states "Unknown paths return ErrUnknownPath (checkable via errors.Is)", but the architecture prose at line 132 says "Unknown paths: registeredSchema() returns "" -> ValidateContent() returns nil." The latest commit (f2358b0) fixed the code snippet but missed the prose three paragraphs below it, leaving the document internally contradictory.
| - **Unknown paths**: `registeredSchema()` returns `""` -> `ValidateContent()` returns `nil`. | |
| - **Unknown paths**: `registeredSchema()` returns `""` -> `ValidateContent()` returns `ErrUnknownPath`. |

🟡 Checklist marks 'returns nil for unregistered paths' as complete but implementation returns ErrUnknownPath
The checklist item is checked off ([x]) asserting the implementation "Returns nil for unregistered path patterns." This is factually false — the code at internal/schema/validate.go:46-47 returns ErrUnknownPath and the test at internal/schema/validate_test.go:128-135 asserts errors.Is(err, ErrUnknownPath). A checked-off item that contradicts the actual code undermines the checklist's role as a verification artifact.

| - [x] Returns `ErrUnknownPath` for unregistered path patterns (checkable via `errors.Is`) |
