Drew T 69dee1d429 docs(phase-29): T50 + SESSION-23 REVISED final checkpoint
T50 func_80135260 family: the §53 carve path banked 4/137 (all SC07), 133 gate-fail, tree clean
after every revert. The 3,744-site conform_decls between runs changed NOTHING for this family (99
attempts observed mid-run, 0 banks) — it is byte-neutral and axis-complete so not harmful, but my
inference that this family shared func_80177DA8's blocker was WRONG: same SC07-only signature,
different cause.

THE REAL BLOCKER, LOCATED: staged siblings are correctly remapped (family_remap works). The draft
requires 4-byte POINTER decls for the contested data symbols — the canonical extern u8 +
(*(u16**)&sym) form makes gcc CSE &sym into two callee-saved regs, costing a 7th saved register and
3 extra instructions (the identical +3 measured on the exemplar). And every sibling host TU carries
the same FILE-SCOPE blocker the exemplar did: verified on ov_SC01_000, whose host TU declares the
contested symbols at file scope (lines 3053-3056) alongside 18 block-scope occurrences. A file-scope
decl constrains every later function in that TU — the T48 finding.

So the fix is the T48 lever replicated x137: scope those decls into their consumers per sibling TU.
Byte-neutral on the exemplar (proven in two steps). That is a TOOL, and it is worth ~18,000 ins.

Also: gather_externs' warning naming func_80135D20 is a COMMENT-SCANNING FALSE POSITIVE (the symbol
appears only in header prose and is defined in another split file). Fires on all 137, masks real
causes. Same class as the Phase-19 garbled-hint bug.

CHECKPOINT REVISED (supersedes the earlier SESSION-23 block): 975 functions banked, reconciled
against the metric (fn-count 319,549 -> 320,524) with the per-task recount agreeing exactly. Fleet
85.5% instr / 76.1% distinct / 90.62% fn-count. R22 140/140 run 11x, dedup 1886/0, 0 NON_MATCHING.
Ranked START-HERE (decl-scoping tool first), the four strategic changes, my five recorded errors —
whose common thread is inference from partial output instead of measuring — and the carried defects.
