Drew T d4dc533f54 feat(phase-29): T52 — func_80135260 swept 132/132 (0 failed); the family goes 4/137 -> 137/137
T51's payoff. The invocation is IDENTICAL to the T49/T50 runs; the only variable is T51's decl
scoping.

  T49/T50 (pre-T51)  4 banked / 133 gate-fail   (and all 4 were SC07 — a different cause)
  T52 sample (8)     8 BANKED / 8               52s
  T52 rest  (124)  124 BANKED / 124             13m04s
  TOTAL            132 / 132, ZERO failures

So the 133 "gate-fails" were never a codegen wall — they were one file-scope declaration per sibling
TU. Fifth time this phase a wall has resolved to tooling/plumbing.

GATES (from a genuinely clean tree): R22 clean-fleet `make clean && extract-all && check-all` ->
140 passed, 0 failed of 140. `make tools-health` OK — corpus 0 PHANTOM + 0 TRUNCATED, cdecl,
audit-binaries, report/lint/dedup 1886 validated / 0 failed (C1 239604/239604). 0 NON_MATCHING (G4).

METRICS (reconciled against make report, not asserted):
  instr-weighted   85.5% -> 85.7%   11240111 -> 11258063 = +17,952 ins
  distinct-code    76.1% -> 76.4%   67687 -> 67812 unique fns (+125)
  fn-count        90.62% -> 90.65%  320524 -> 320656 = +132 functions
  INCLUDE_ASM stubs 33189 -> 33057  = -132
+17,952 templated instructions against T50's ~18,000 estimate. distinct-code gains 125 not 132
because seven siblings are byte-identical to code already counted unique.

ALSO SETTLED:
- item 3 is now byte-confirmed, not just inspected: [gather_externs] warned "func_80135D20 ... the
  sibling will not compile" on ALL 132, and all 132 BANKED. A 100% false-alarm rate on this family,
  actively masking real causes. cdecl._mask is the fix (T51 used exactly that).
- the T51 pre-pass is now worth folding into jtbl_family_bank; T51 withheld that pending a measured
  payoff, and 4/137 -> 137/137 is it. Next task.

config/ (per-overlay splat.*.yaml + overlays.mk, written by the carve) is staged alongside src/ —
the `git add -A src/` omission this phase already recorded once.
