Drew T a302908f24 fix(phase-26a): A3 — target selection was blind to 91.6% of the remaining work; now derived 
The audit's CRITICAL finding, fixed at the root. Both tools now derive the corpus from
tools/corpus.py instead of keeping their own decaying copy of the tree layout.

build_fuel_manifest.live_stubs() — a hardcoded 3-file dict {<ov>.c, _a.c, _o0.c}. ov_SC01_077 has
FOURTEEN .c files, so it saw 30 of 264 stubs AND REPORTED SUCCESS. Everything downstream consumes
this manifest — worklist.py (100% of its rows), wave_targets.py (100% of its pools) — so:

    targets            30  ->  263
    reach-134 targets  10  ->  127      (the ENTIRE high-ROI band was invisible)
    remaining gain  83,305 ->  994,633 instructions

994,633 is the A2 audit's predicted figure TO THE UNIT — a fourth independent confirmation
(auditor -> skeptic -> corpus.py -> this). Four of the five highest-leverage functions in the whole
project sit in split regions no tool could see; the top one, func_80178004 (165 ins x reach 134 =
22,110), had never been nominated by anything.

It rotted SILENTLY: .run/fuel_manifest.json (Jul 8) recorded 130 stubs; the same code today returns
30, because the Phase-26 jr splits moved ~100 stubs out from under a dict literal last edited in
Phase 22. Nobody noticed, because a target that is never nominated produces SILENCE, not an error.

wave_targets.REGION_SUB / asm_for() — a 3-entry dict with a silent fallback to the main subdir.
ov_SC01_077 has TWELVE asm subdirs, so 78 of the 87 targets any --class wave emitted handed a
drafter an asm path THAT DOES NOT EXIST. The drafter then drafts against nothing, and the wasted
attempt is booked in the backlog as a *matching* failure — which feeds reserved_walls() and
PERMANENTLY BLACKLISTS a function that was never actually attempted. A silent skip compounding into
a false wall. Now 263/263 asm paths resolve, 0 missing; asm_for() raises rather than guess.
Also: --region's 3-value whitelist defaulted to 'main', which sees 13 of 264 stubs even with a
correct manifest -> default 'any', free-form.

R33 throughout: the INCLUDE_ASM line is SELF-DESCRIBING (its first argument IS the asm subdir,
because splat wrote it there), so both dicts were second copies of a fact the tree already states.
A dict literal is strictly worse than the filesystem AND it fails OPEN. Never re-introduce one.

No build impact (selection/report tools only); docs/worklist.md regenerated with the honest numbers.

# Worklist — remaining functions ranked by byte-weighted project gain
> Generated by `tools/worklist.py` from `.run/fuel_manifest.json` + `.run/backlog.jsonl`. Ranked by **byte-weighted gain** `gain_ins = reach × nins` (fleet instructions made byte-identical once matched **and** propagated ×134 — the decomp.dev-comparable metric the giants move, NOT function-count). `%rem` = share of ALL remaining gain; `cum%` = running total (shows how few giants capture most of it). `close` = backlog match_one mismatch count (lower = nearer; blank = not yet attempted). Byte-gate (harvest_verify) is the sole arbiter (G3/P9).
**Live stubs:** 263 · **total remaining gain:** 994,633 ins (3,978,532 bytes ×-fleet)
