Christopher Williams 677d982398 phase12: merge 6 — worker A's 572 B body -> 621 bodies / 630 regions; exclude the 0x800C3490 fragment
Worker A's third claim, verified from a fresh --work dir against the exact md5 in the claim,
merged to a candidate, gated whole-binary, promoted only on result=MATCH. It is the largest body
any worker has taken this phase (572 B).

**ADJACENCY IS NOW 3-FOR-3 FOR WORKER A, ACROSS THREE BANDS.** 0x800297F4 (204 B, band 0) ->
0x800298C0 (392 B, band 1) -> 0x80029A48 (572 B, band 2): three CONSECUTIVE bodies, 1168 bytes,
four spellings total, with the density ranker not involved in any of the three picks. The chain
ends where no row starts at the next boundary. That is the strongest single piece of dispatch
evidence in the phase, and it is why the fresh-band files were re-cut to put adjacency above
density inside a band.

Worker A's lever, recorded because it is an operator RECOVERY rule rather than a spelling tip: the
original is `if ((x1 < 0 && x2 > 0) || (x1 > 0 && x2 < 0))`, and the truth-table-equivalent
if/else ladder is EXACTLY ONE INSTRUCTION SHORT. The emitted stream is `bgez x1` / `bgtz x2` /
`blez x1` / `bgez x2` -- each term's first test branches over its own second test -- and the ladder
has no `bgez x1` to emit. So the four BRANCH SENSES let you write the operator down without
guessing; cookbook 83's "branch direction distinguishes && from ||" turned into a recovery rule.
And `(x1 ^ x2) < 0` is the same predicate with the wrong codegen: the original compares.

**0x800C3490 IS EXCLUDED FROM THE WORKLIST.** Cookbook 114 (worker A, Phase 10) records it as a
FRAGMENT: it starts mid-expression, its body is a SHARED TAIL (`addiu sp,sp,48; jr ra`) that also
appears at 0x800C3470-0x800C348C, and it cannot be matched standalone. The extents table still
grades it `exact` with `term=jr_ra` because the boundary walk sees a well-formed terminal, so the
tool cannot catch it -- which is exactly why it needs a recorded exclusion rather than a tool rule.
Worker A recognised it for the SECOND time in Phase 12 and skipped it instead of spending reading
budget, which is the signal that the exclusion belongs in the Makefile: a row that has to be
re-identified by hand every phase is a row the dispatch should not be offering.

Added with its provenance in the Makefile comment, the same mechanism Phase 10 used for
0x8010080C's false extent start. excluded_named_exclusion 8 -> 9.

Ledger updated with merges 2-5, the cc1bin lever and its gate, the mechanism correction, the gp
pair rewrite and both of my failures in it, the dispatch measurement (369 of 993 rows abut SOME
region = noise; only 5 abut a PHASE-12 match = the signal), and the partition-membership fix.
