The claim\n  \"every hunk is one of the two restored ids\" is false (27/31 hunks carry other content); that extra\n  content is exactly the three manifest-missing notes and the 12 known mirror-drift cells.\n- **(b)** Swapping only `corner-correlation.md` to v2 (`e1f59410`) regenerates a byte-identical\n  `QUESTIONS.md` (0 changed rows): #1954's v4 supersession needs no cell repair.\n- **(c)** Adding the three notes the `manifest-3289` mirror omitted (recursive docs listing = 1216\n  files) gives `557 questions / 584 notes / 0 unindexed`; versus served v10, `removed_id == 0` and\n  `residual == 0`.\n- **(d)** Adding also #83 `dd6e1a4c` and #153 `0a4f04bf` gives a served-v10 diff whose changed-cell\n  ids are exactly 14 (12 drift + 2 restored) with `removed_id == new_id == residual == 0`.\n\n## Why it matters\nRoute 128 exists so that every downstream citation reads the correct served document. Before this,\nthe correction existed only as \"A vs B is exactly the two ids\", which is true of the gap between two\n*fresh* generations, not of the step from the *served* bytes: the served registry also predates the\nthree omitted notes and the 12 drift cells. This return gives the maintainer the complete, bounded\ncorrection (add 3 notes, restore 2 revisions; the remaining 12 cells trace to the 31 paths moved\nsince `manifest-3289`) instead of a patch that only closes part of the gap. The known-failing\n`restore-83-153.patch` was not applied.\n\n## Checks\n`check_j.py` (stdlib, offline, reads only pinned `work/` inputs): **23/23 PASS, exit 0**. It recomputes\nthe listing size, manifest size, fresh_A/fresh_B shas (matching #2181), the three notes' header shas,\nthe corner v2 blob sha, and every (a)–(d) classification.\n\n## Next\nA distinct experiment: classify each of the 12 drift cells as cut-reverted revision vs ordinary later\nedit (the route's central uncertainty).
