Drew T a1f1a948af feat(phase-29): h_norm-remappable pool — +4,919 ins banked, no cracking, no agent
- BANKED (each whole-binary byte-gated; make check-all -> 140 passed, 0 failed of 140):
  func_80130D48 ×4 (1,064) · func_8018F3E4 (478) · func_8018B3D0 (478) · 13 × 223-ins siblings
  of func_8017E6D8 (2,899). distinct-code 3,833,224 -> 3,838,143 = 68.0% -> 68.1%.
- TWO OF MY OWN COUNTS COLLAPSED UNDER SCRUTINY BEFORE I ACTED ON EITHER (R14/R35):
  "func_8017CA80's family = 102 unmatched" was really 13 -- my count tallied family members whose
  NAME appears as a stub anywhere in the fleet, not instances actually unmatched (a semantics
  error, not arithmetic). "56,267 ins remappable" was really 8,114 -- 86% was the known -O0 /
  deferred set (the func_80144B9C whale, the func_8013C414 cluster). I nearly recommended a
  target on the first number.
- THE §77 CARRY GAP IS THE DOMINANT COST OF MECHANICAL REMAP: 23 of 27 first-pass CC1-FAILs.
  NEW .run/giants/s19_remap_tu.py sources the preamble from the exemplar's OVERLAY TU (the block
  between the previous top-level `}` and the def), applies family_remap's own substitution map,
  and adds the two includes match_one never adds -> 21 drafts went 0 MATCH -> 14 MATCH. The 13
  223-ins siblings share ONE exemplar, so a single preamble fix cleared all 13.
- USEFUL ASYMMETRY: func_8018F3E4/func_8018B3D0 FAILED match_one but BANKED in the whole-binary
  gate -- the real TU supplies decls the standalone compile lacks. A match_one CC1 FAIL is not a
  reason to skip the real gate on a remapped sibling.
- RESIDUAL 3,195 ins, causes NAMED not guessed: func_8017D5C0 (952) matches standalone, gate
  reports `conflicting types for memcpy` = the §58 red-herring (a warning from an unrelated TU
  position; SESSION-14 hit the same label and the true cause needed a hand-splice + real cc1
  stderr). func_80166994 ×3 + func_8016A290 ×4 still CC1-FAIL after the TU carry.
- FULL R22 DEFERRED DELIBERATELY: make clean wipes asm/, which the concurrently-running BF14
  agent reads on every probe. This batch changed only src/*.c (no config), so check-all is sound;
  the clean R22 must still run once the agent finishes.
