Four commits of chunk work -- uniform record length, the leading-byte phase
counter, the two-byte record index, and the PCSX2 RAM findings -- were written to
docs/formats/core-data-regions.md and docs/plan/pcsx2-verification.md but never
reached the roadmap, because the scripted replacements kept missing their target
text and I did not check that they had applied.
That is the staleness complained about earlier recurring through a different
route: not a missing edit, but a silently-failed one. The tie, collision and
level_overlay entries had landed; only the chunk ones had not.
Rewritten from the commits rather than from memory, and the numbers are the ones
the tests assert: 1,509 chunks, 34,491 records, uniform length 1,509/1,509,
phase counter 1,262/1,509, index rule 1,235/1,509, RAM prefix 02 00 on 90/90.
