 other when `docs/README.md` and `docs/plans/2026-08-20_stack-docs-flatten-and-alignment.md` disagree
 about the contract, and they already differ (the plan's enum has 7 values, the README's now has 6).
 That is an authority question, not a classification one.

+## The old schema DID have a consumer, and CI found it
+
+vision's C2 concluded "no consumer found" after searching by parsing primitive rather than by key
+name. fred's decision A rested on "no installed base to protect." I accepted both. **All three of
+us were wrong, and the full test suite is what proved it.**
+
+`packages/mosaic/src/installation-documentation.spec.ts:39` asserted:
+
+```ts
+expect(markdown).toMatch(/^---\n[\s\S]*?\nstatus: current\n[\s\S]*?\n---\n/);
+```
+
+That is a raw regex over the markdown text, not a front-matter parse and not a key lookup, which is
+exactly why a search organised around parsing primitives could not see it. It pins
+`docs/USER-GUIDE/getting-started/quickstart.md` to the old vocabulary. Replacing `status: current`
+with `status: active` turned it red.
+
+Updated to `status: active`, the contract's value for "in force", with the reason in a comment
+beside it. Verified by evaluating both regexes against the real file: old `false`, new `true`.
+Control: a page carrying `superseded-by` still fails the new regex, so the assertion still asserts
+something rather than matching anything with front matter.
+
+**The method point, which outlives this file.** CI 2592 ran 1617 tests against the stamped tree: 1
+failed, 1616 passed. That is a stronger consumer search than any grep the three of us ran, because
+it does not depend on guessing how a consumer reads the file. **Run the suite before concluding a
+documentation change has no code consumers.** Two independent seats and a reviewer searching by
+hand missed the one that existed.
