re: first audit of INDEX against the pages it links -- 3 of 8 rows were stale

INDEX is read every iteration and is the first thing a new reader meets, and I had
admitted three times to never auditing it. Found by accident: I was about to spend
a boot measuring whether A skips a movie because INDEX said 🟡, when movie-binding.md
had it settled since 2026-08-28 with a three-boot baseline and a delivery counter,
and HANDOFF carried it correctly. The staleness was in the index alone.

Three stale rows fixed: movie skippability, SE audio extractability, and B leaving
the main menu. Five other hits read and left alone -- index and page were talking
about different clauses.

One of the three should have been caught by check_refuted.py: REFUTED holds the
same dead claim with a different second clause, and the register matches exact
wording. Its docstring documents that weakness; this is the first live instance.

Also flags a within-page contradiction not fixed here: menu-audio-cues.md line 81
still heads a section saying SE audio is not extractable, which its own line 189
refutes.

+"""Does an INDEX.md row's status agree with the page it links?
+
+`INDEX.md` is read every iteration by both agents and is the first thing a new
+reader meets. sylpheed-port's phrase for it is "an index is an amplifier": a
+status that is wrong there is wrong everywhere it is quoted from.
+
+Found by accident: INDEX called movie skippability 🟡 unsettled while
+`movie-binding.md` had it ✅ settled since 2026-08-28, with a three-boot baseline
+and delivery confirmation -- and HANDOFF carried the answer correctly. The stale
+row is in the index alone.
+
+⚠️ THIS PRINTS A LISTING, NOT A VERDICT. An audit that invents defects is worse
+than no audit, because its false positives are indistinguishable from its true
+ones until each is opened by hand (sylpheed-port paid for that, and so did I with
+a 7-candidate/0-real sweep). A row can legitimately say 🟡 about one clause while
+its page says ✅ about another. Every hit here is a PROMPT TO READ.
