/**
|
|
* Doc-sync gate: verify that doc references written in TypeScript COMMENTS
|
|
* resolve to a file that exists. Source comments cite docs by root-relative
|
|
* prose path — `see docs/rfc/implemented/testing/2026-06-19-acp-snapshot-tests.md`,
|
|
* `docs/architecture.md § Where New Behavior Goes`. `verify-md-links` parses Markdown
|
|
* link AST and never sees these, so a doc rename or move could silently orphan
|
|
* a `.ts` comment that points at it. The RFC classification reorg
|
|
* ([the classification RFC](../docs/rfc/implemented/process/2026-06-20-rfc-classification.md))
|
|
* is the motivating case: it moved every RFC under a `{class}/` folder, and
|
|
* several `.ts` doc comments cite RFC paths that changed.
|
|
*
|
|
* Detection is a token scan, NOT an AST walk: doc refs live in free prose inside
|
|
* comments, not in a structured form. We match `docs/<path>.md` tokens and
|
|
* REQUIRE the `.md` extension, so extensionless prose (`docs/postmortem/0001`,
|
|
* `docs/architecture.md § Where New Behavior Goes` — the section suffix is outside the
|
|
* token) is left alone rather than misread as a path. Each token is resolved
|
|
* ROOT-RELATIVE (the way the comments are written) and must exist on disk. This
|
|
* is checker, not fixer: it reports and never rewrites.
|
|
*
|
|
* Scope is repo-authored TypeScript under `packages/**` and `examples/**`,
|
|
* excluding built output (`lib/`, `*.d.ts`) and `vendor/` (pinned upstream
|
|
* source we do not own). The scan is purely textual, so it does not distinguish
|
|
* a token in a comment from one in a string literal — a `docs/….md` string in
|
|
* code is checked too, which is harmless (such a path should resolve anyway).
|
|
*
|
|
* Run: `tsx scripts/verify-doc-refs.ts`.
