The flywheel step (R16/R30): turn the wave-1 + SIGABRT byte-proven findings into cookbook/codegen-map knowledge, in the producing session. The distillation REWRITES wall verdicts, so accuracy is load-bearing. - cookbook §42e-CORRECTION: the "pin-crash wall" (register-pin-heavy families "SIGABRT the sibling TU, ov077-TU-context-specific, NOT ×134-recoverable") is REFUTED. The SIGABRT is real (sched.c:2725 create_reg_dead_note, a sched1 REG_DEAD-note conservation bug) but was TRIGGERED by extract_unit dropping file-scope #define macros (the T5 bug) -> implicit-call GTE ops -> caller-saved pins in the fatal shape. Only 1 of 4 families genuinely crashed; 3 were exit-33 plumbing folded into one crash bucket. Fixed, all 4 stage 133/133 clean. Per-pin predicate recorded. P31's pin route is OPEN. - cookbook §44-Lever-5: the 3 functions it cited as intrinsic (func_8014D820/8016CBC0/801670E4) are each oracle-refuted (2 cracked roots + 1 RC-6-not-S3). Corrected the "NEVER ship pinned, it SIGABRTs" claim per §42e-CORRECTION. - gcc-2.7.2-map/regalloc.md §H: THE reg_renumber-swap oracle (discriminate RC-6 allocation from S3 scheduling in one gdb run — patch reg_renumber at reload entry, swap the contested regs; byte-exact = pure allocation), RC-14 reused-load-temp serialization (the MERGE pole; pin-free, cheap-Opus), RC-15 the density dial across a floor_log2 boundary (subsumes "coalescing knife-edge"), and the local-vs- global allocation tie as a precisely-named honest sub-class. Continues the §F/§G RC-6-downgrade series. - decision-log.md R31: the 3 Phase-27 strategic findings (disc is bigger: 140 + 39 modules; a wall was our tool again; a cheap win is dead) + the through-line — the roadmap's numbers were red-teamed, the tools under them were not, until this phase. func_80176734 (fresh-core wave-2 agent) still running; its findings fold in before the PhaseEnd.
