test(qa): verify exact long timeline content preservation

 The final separate Phase9 diagnostic lane completed **18/18**, zero failures/skips/flaky/retries, on the frozen825-input manifest (`phase9-frozen`, exit0 at20:25:16UTC). It includes12 route/theme/locale/width cases, four settled accessibility cases, one RD21 characterization and one bounded workload. **A passing characterization does not qualify the unsafe behavior it records.** The earlier18-case run and the later16pass/2fail transition observation remain superseded raw evidence.
 
+That diagnostic snapshot is retained as [source-manifest-before-admin-fixture.json](../p9-00/source-manifest-before-admin-fixture.json). The final ordinary-run snapshot changes only the locale-sensitive Admin test locator; [exact delta](../p9-00/admin-fixture-delta.json) proves product/build/diagnostic/core inputs are unchanged. No diagnostic result is claimed to execute an ordinary fixture it does not load.

 ## Native documents
 
 Fresh real preview and native exported PDF bytes from the retained corpus passed **16/16 fixtures /36 pages** under the unchanged oracle: exact page count/membership, physical dimensions ±0.5mm, marker positions ±2mm, font sizes ±0.5pt and original RGB tolerance. Nine defaults, long EN/NB, 8mm Letter, 28mm roomy, grid/bubbles, long sidebar and unbreakable boundary fixtures are included. No renderer geometry or tolerance changed.

+**3/3 passed**, zero failures/skips/flaky/retries, `volume-complete`, exit0 at00:27:14 UTC on23October. Full TypeScript checking also passed. An initial type-only import error was corrected; review then strengthened timeline preservation from a prefix check to exact content-by-ID comparison. The complete three-case successor passed on the final source. Earlier passes are retained as superseded evidence; no product code changed.
