docs: make the two schema documents read as siblings - #24
Conversation
Closes #10, the documentation gaps left by #8 when it kept a threat-model pull request from also rewriting requirements-matrix documentation. The requirements schema carried its rules inline in dense table cells where the threat model pulls the same concepts into their own sections. It now has Traceability, Ownership, and Evidence sections, which is not only symmetry: each answers a question the table could not. traceability.adrs and traceability.threats had no stated format while risks in the same cell did, leaving an author with no rule to follow. There is no rule, deliberately. A requirements matrix is validated on its own — nothing passes a threat model alongside it, and validate -requirements runs the other way, letting a threat model resolve its links against a matrix rather than the reverse. Asserting a threat-ID shape this tool cannot check would be worse than saying plainly that these are free text, so the docs now say which, and where to express the relationship so it is actually verified. Both document types use "evidence" and "owner" for different things, and config.md gave verification_levels and evidence_levels identical example values, which made them read as one vocabulary. schema.md now carries a table of exactly those two collisions, since it already hosts the cross-type conventions, and the examples differ. Unify validateLocalPath with check.RepoRelativePath. The two had diverged: the configuration's copy swept only ASCII space and tab, so a path with a non-breaking space or a Unicode line separator passed configuration validation while identical text in a document was rejected. Configuration keeps its tighter 256-byte bound, applied first, because that is the limit worth reporting to someone editing a config file. This rejects configuration paths that were previously accepted. Mutation-tested: restoring the ASCII-only sweep fails exactly the non-breaking-space and line-separator cases and nothing else.

Full details: Title checkExplanation The title accurately describes the primary documentation change: aligning the requirements and threat-model schema documents as sibling documents. It does not mention the related path-validation change, but the title need not cover every detail. Full details: Linked Issues checkExplanation The pull request satisfies all coding-related objectives in issue Full details: Docstring CoverageExplanation Docstring coverage is 50.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 6 functions across 2 files. (1 skipped: 1 unsupported.)

The Fixed entry read "the configuration's swept only ASCII space and tab" — a possessive with no noun. Name the copy it is possessing.

Four gaps, four answers
traceability.adrsandtraceability.threatshad no stated format whilerisksin the same table cell did. The answer is that there is no rule, deliberately — and saying so is the fix. A requirements matrix is validated on its own: nothing passes a threat model alongside it, andvalidate -requirementsruns the other way, letting a threat model resolve its links against a matrix rather than the reverse. Asserting a threat-ID shape this tool has no way to check would be worse than free text.

Now symmetrical, and it explains the asymmetry that matters: the requirementsownercarries routing only, with no accountableprincipal, because a requirement records an obligation while a threat records residual risk somebody has to carry.validateLocalPathduplicatedcheck.RepoRelativePath— and the copies had diverged. The configuration's swept only ASCII space and tab, so a path carrying a non-breaking space or a Unicode line separator passed configuration validation while the identical text in a document was rejected.
