- dedup_propagate split-aware: overlay_files() handles ov_SC01_077's Phase-19 split (main + _a/_o0);
source-find scans all, member-loop edits the right file, structural-check spans all. Single-file
overlays unchanged (default path). Validated: source-find (--check-only 134 members) + fail-closed revert.
- cast_call_sites --src-file: canonicalize callee decls against the file the draft lands in (cross-file
loose typing — a callee declared differently in main vs _a.c). Default = main, unchanged.
- FINDING (cookbook §24): the fresh reach-134 fuel (66+ fns) is in ov_SC01_077_a.c (a tooling gap, not
difficulty); bodies are matchable (func_8012C098 cast-banked) BUT matching/propagation hits the same
§16/§20 loose-typing wall (func_8012C098 cross-overlay def-conflict -> x1; func_8012F274 within-_a
RotTransSV multi-sig). x134 yield uncertain -> a small measurement wave is the next probe.
- no net banks this turn; fleet 62.31% unchanged; ov_SC01_077 verified d19c9580 (R22). sig_unify reverted.
- tools/cast_call_sites.py: per draft, callee whose canonical TU sig != draft's
intended sig -> decl->canonical (kills in-TU conflicting types, keeps symbol in
scope) + call-site cast ((ret(*)(args))func_X)(args) (codegen-neutral: gcc folds
the cast of a known symbol -> direct jal). Pure --in/--out; whole-binary gate is
the arbiter (G3/P9). Pipeline: canon_resident_calls -> cast_call_sites ->
sig_unify -> harvest_verify --chunk 1
- recovered 6 of T6 batch-1's 33 gate-fails byte-identical (func_80153C44/8015CF58/
801711FC/80161BE0/801683D8/8015F948); 5 propagated x134 + 1 local; check-all 136/136
- R14 CORRECTION of cookbook §20's '~33' projection (byte-proven): the batch is NOT
mostly callee-conflicts — ~6 callee (cast-recovered), ~18 DEF-side loose-typing wall
(def's matchable sig conflicts with the unchangeable caller-canonical; caller-side
fix BLOCKED because INCLUDE_ASM declares no symbol -> a shared macro's internal
extern is load-bearing in the 133 stub overlays), + a small DATA tail. The def-side
needs re-drafting under the caller-canonical sig (future wave), not a text transform
- cookbook §20 RESOLUTION + SETUP tool inventory (R16/R21/R30); CURRENT_PHASE log (R28)
- fleet 58.63% -> 58.82%, dedup 1501 -> 1508, 0 NON_MATCHING (G4)
