When you cite a source location, include both the line's text and its coordinate. A quoted string is self-verifying — a later reader can grep for it and either find it or learn immediately that it moved. A bare coordinate fails silently: it points at whatever happens to be at that line today, which may be unrelated code.
Pattern that survives drift:
recordCodingFailureis called from the workflow's catch atworkers/api/src/workflows/coding-session.ts:733
Pattern that rots silently:
the call is at
coding-session.ts:705
The text form is the claim. The coordinate is a locator — useful when found, harmless when stale.
Stamp asserted measurements with the command and the date:
grep -rn "z.number()" workers/api/srcreturned 32 on 2026-08-18.
A bare count with no command or date cannot be re-verified; a reader running the check later cannot tell whether the number changed or whether they ran the wrong query.
Branch names are deleted after merge. If you reference a branch (feat/some-branch), also include what survived it — a commit SHA, a closed issue, or the feature that landed.
The CI guard check-doc-citations.mjs enforces that every backtick-quoted file:N reference in docs/ and platform-docs/ resolves to exactly one file in the repo tree. A cited path that matches zero files, or that matches more than one (ambiguous), fails the build.
What is checked: path resolution only — whether the file exists and is unambiguous.
What is NOT checked: whether the line number is still correct. Apply the same rule as for issue bodies: quote the relevant text alongside the coordinate so a reader can grep for it.
<!-- Good: full path, text quoted -->
`coding/headless.ts:291` (`resumedConversation` getter)
<!-- Good: unique suffix, text named -->
`lib/connectors/manifest.ts:239` (`AUTH_TYPES`)
<!-- Bad: ambiguous bare name -->
`manifest.ts:216`
<!-- Bad: full path but no quoted text — line drift is invisible -->
`coding/headless.ts:260`If a file name is shared across packages (e.g. manifest.ts), use a longer prefix that makes it unique (lib/connectors/manifest.ts). Check uniqueness with:
git ls-files | grep -E '(^|/)manifest\.ts$'
