Drew T 8b828f1ea6 feat(phase-29): BEHEMOTH func_8017BF14 CLOSED — 45 -> 0 (4,763 ins, the largest match yet)

- 45 -> 37 -> 33 -> 21 -> 11 -> 3 -> 2 -> 0, reproduced 3x from independent work dirs. Verified
  independently before believing it (R14): match_one MATCH (4763 ins), then harvest_verify
  --binary ov_SC03_116 BYTE-IDENTICAL, then R22 clean-fleet 140 passed, 0 failed of 140.
  distinct-code 3,838,143 -> 3,842,906 = 68.1% -> 68.2%. instr 80.5%. Agent was interrupted by a
  weekly API limit and RESUMED FROM ITS TRANSCRIPT -- its round-2 harness survived, nothing was
  re-derived.
- §80 THE PROCESS CORRECTION, worth more than the match: A DO-NOT-RE-BUY ENTRY IS SCOPED TO ITS
  BASE, NOT TO THE FUNCTION. Three of round 1's ~40 measured negatives INVERTED on round 2's
  base -- the same edit (qsingle23) measured 1,040 mismatched on the 45-base and 11 on the
  21-base. Re-testing the round-1 negative list cost ~20s and produced THREE of the seven winning
  levers. Such a table records (edit, base) -> result, NOT edit -> useless; after any lever that
  moves the base materially, RE-RUN THE NEGATIVE LIST. This retroactively qualifies every
  do-not-re-buy table in the cookbook (§45, §60b, §75a, §76, §78, §79). Concrete: round 1 measured
  "removing the va->$t2 pin costs 4% elsewhere" => keep the pin; on a base with c0..c3 at function
  scope, removing those pins is worth 21->13. Same experiment, opposite conclusion.
- MY FLAGGED "#1 MOVE" LOST, and the failure is the finding. I briefed variable REUSE (§45-A /
  RC-14) as the top lever because it took func_8017F510 from 97->10. Swept in full here: EVERY
  merge lost, 43-3294 across 8 merges. Reason: the TRI and QUAD grants did not differ by RANK but
  by IDENTITY -- two independent allocno sets, and re-ranking inside one set cannot fix a two-set
  problem. Diagnose ranking-vs-identity before reaching for a merge. The actual fix (c0..c3 at
  FUNCTION scope, 33->21) was read off the two matched relatives (b5:310, b4:338) and confirmed
  against the target -- the 4th time today that reading a matched relative beat the clever lever.
- PIN'S HIDDEN COST, cited: combine_regs' hard-register branch (local-alloc.c:1795, reached from
  :1295 with already_dead==0) records the pinned reg in qty_phys_sugg UNCONDITIONALLY -- no death
  guard. A pin invites local-alloc to tie producer chains into it. New cure R7: a zero-byte
  __asm__ ref keeping the pinned value live past the temp so find_free_reg can't honour the
  suggestion -- closed the last 2 ins (c1->$a0 is uniquely load-bearing; every alternative pin
  lost 64 ins).
- §78's attribution primitive RUN and REPRODUCED: under -fno-schedule-insns, -fno-schedule-insns2
  and both, order unchanged => the rgb transposition was never a sched.c decision.
- Cold-start economics complete: round 1 = decode + exact length + exact frame + 99.06%; round 2 =
  the last 45, and cheaper. Budget TWO passes at this size. 5th source copy-paste artefact found.
