Christopher Williams 4a731de2d5 phase10: CLOSE — PhaseEnd, digest, verification record, cookbook 41-57
MILESTONE MET AND EXCEEDED: 484 distinct matched bodies / 493 registered regions
(target 475, from the 400 baseline) — +84 bodies. Developer confirmation of the
milestone was requested and given before any close record was written.

Closing checklist all green from clean:

New records:

  phase-ends/DIGEST.md                the Phase 10 digest entry

The headline finding is methodological (finding 41, THE SIZE-BAND LAW): the matched
corpus median is 48 bytes with 454/459 at <=200 B while the remaining levered rows
had a median of 456 B, and two independent measurements — one controlled — put the
small band at 1-2 attempts per row against 1-in-12 for 200-800 B.

The phase's character: five of the coordinator's own generalisations were bounded by
workers (rare-epilogue class, register-field diagnostic, polarity lever, goto
trigger, load-delay consumer form). The rules that survived are the ones that were
bounded.

Five incidents recorded rather than smoothed over; the candidate gate rejected three
batches and the tracked registry was never corrupted. Scope held: the blocked classes
stay excluded, no scheduler-changing flag was granted, and inline asm was extended
only to shapes C provably cannot express.

STOPPING HERE. Phase 11 does not begin in this session.
