- THE CAP TOOL tools/cast_call_sites.py (§17a-1 callee-cast): per draft, callee whose canonical TU sig != draft's intended sig -> decl->canonical + call-site cast ((ret(*)(args))func_X)(args) (codegen-neutral; gcc folds the cast of a known symbol -> direct jal). Recovered 6 of T6 batch-1's 33 gate-fails byte-identical (5 x134 + 1 local). Pipeline canon_resident_calls -> cast_call_sites -> sig_unify -> harvest_verify --chunk 1. - T3a CRACKED (not cited): the %lo-folding indexed-global -O0 residual falls to the array-of-STRUCT idiom (extern Struct base[], sizeof==stride, base[i].field; NOT *(T*)(&sym+i*stride) which materializes &sym). func_8013B7AC banked. Reusable idiom fleet-wide. cookbook §18/§20. - THREE byte-proven findings (R14): (1) the wave cap is the DEF-side loose-typing wall, not callee-conflicts (the §20 "~33" projection was wrong); (2) the -O0 cluster is OVERLAY-LOCAL, not reach-134 -> the ×134 rollout is INVALID; (3) data-cast is MOOT (0 real data conflicts). - T1 typedef type-lift (+0.35%, 9 fns x134); T2 exemplar_miner router; T4 codegen map (cookbook §20); T6 batch-1 (+0.28%, 8). dedup 1485->1513/0 failed. check-all 136/136 BYTE-IDENTICAL (R22); 0 NON_MATCHING (G4). fleet 58.00% -> 58.82%. - rule R30 (capture context-dependent knowledge before a fresh session). worklog -> logs/Phase20.md. - bumps 1.18.0 -> 1.19.0
