Drew T 80b89d8a2d feat(phase-23): LLM matching tier + the Fable5 wall-breaker + the gcc-2.7.2 codegen map (v1.22.0)
- LLM TIER (T1-T10.9): tools/serve_local + api_draft + lora_grind + bulk_harvest + the LoRA
  pipeline (v3 model). Local v3 saturated <=15 (~1300 banks, $0). Frontier GLM-5.2 (~$4)
  confirmed the def-side wall INTRINSIC + the idiom well DRY at the leaf (both angles).
- THE PIVOT (07-02): Fable5Max reading the gcc-2.7.2 SOURCE matched func_8014EE14, a §20/§10
  store-vs-load giant "CONFIRMED unsteerable" for 22 phases -> the "wall is intrinsic" verdict
  is MODEL-RELATIVE. Generalized to Opus agents applying §30 (2 more giants, 3-5x cheaper).
- §31 THE CODEGEN MAP: 4 Fable5 agents read the whole gcc-2.7.2 source -> docs/gcc-2.7.2-map/
  {sched,regalloc,loop,cse_expr}.md (935 lines, byte-proven residual->lever catalogs) +
  cookbook §31 (index+triage). Broke hoist-vs-remat/delay-slot/coalescing walls. Correction:
  gcc-papermario is 2.8.1 not 2.7.2 -> tools/reference/gcc-2.7.2/ (SETUP §5.6).
- THE WAVE (8 reach-134 near-misses, Opus + §31): 3 leaf-MATCH by lookup (47-137k tok vs
  200-250k walls) + 5 tight permuter seeds (func_80132784 240->4-off!), zero dead-ends.
- 5 giants/hard-fns banked x134 (func_8014EE14/F2E0/150528/149374/144090); fleet 63.66->64.86%,
  136/136 byte-identical, 0 NON_MATCHING. cookbook §30/§30a/§31. No new governance rules.
- FINDING: matching is SOLVED by the map; bottlenecks are now the permuter (S11 seeds) +
  whole-binary integration (auto-bank leaf-MATCHes) -> Phase 24. worklog -> logs/Phase23.md.
