 ## Progress log
 *(append one line per task on completion — the crash-recovery trail)*
+- **T6 (partial) ✓ (2026-07-03):** 🎯 **FLAGSHIP `func_80132784` PROPAGATED ×134** (`commit:0443`) — the 400-ins S11 giant (cracked T4, banked ×1) now byte-identical in ALL 134 overlays, **+1.6% byte-weighted** (the single biggest lever; function-count fleet 64.86→64.90%). **The T6 recovery pattern, proven end-to-end:** the T4-deferred ×1 cap was one straggler overlay (ov_SC02_005) declaring a CONFLICTING caller extern `void func_80132784(s32,s32,s32)` vs the def `(s32,s32,u32)` → `conflicting types` → dedup_propagate's all-or-nothing single-`--addr` plan dropped the whole fn. Fix: reconcile the straggler's caller extern to the def's canonical sig (s32→u32, byte-neutral — the call site casts anyway), then propagate → 134 overlays rebuilt byte-identical, group `E_func_80132784` registered, dedup-check 1784/0. **Clean R22 fleet check-all 136/136.** **REMAINING T6 (the tool):** automate this — detect a straggler's conflicting caller decl → reconcile to the def's canonical sig → re-gate → propagate full (vs. all-or-nothing drop); + the other ×1 classes (func_8014E048 pin/asm self-containment — a DIFFERENT blocker: dedup_propagate's `compiles_standalone` rejects pin/asm bodies; func_80144090 OtBlk type-lift; func_8014F4C0/func_80155800 TU-context leaf-MATCHes in `.run/wave/`).
 - **T5c ✓ (2026-07-03):** 🟢 **TRUE clean fleet 136/136 RESTORED** (first genuinely-clean `make clean`+full-re-extract+check-all green since Phase 21). Fixed the pre-existing Phase-21 (`commit:0292`) rename-propagation breakage: renamed all **62** stale `INCLUDE_ASM(func_<ADDR>)` → curated names across 12 main/library `src/*.c` (800c.c/800c3.c×22/apicard1·2·4/boot.c/libcd1×8/libetc×6/libgpu×3/sgap.c/snd1×7/snd2.c) to match splat's canonical output (proven: splat's fresh stub-regen uses the curated names). **main clean-builds `143dbb89` ✓; fleet 136/136 ✓** (all overlays byte-identical, resident `8e17e02f`). Built **`tools/lint_symbol_refs.py`** (comment/string-aware, func_+D_) — flags any `func_/D_<ADDR>` ref whose addr was renamed (the R22-masked class); caught the T5b macro-call + this INCLUDE_ASM set; now 0 stale. SETUP inventory + CURRENT_PHASE finding updated. Commit: (checkpoint).
 - **T5b ✓ (2026-07-03):** 🎯 **S11 CRACKED — the class verdict was map-incompleteness, not intrinsic codegen** (Fable5 main-loop spike, Drew switched the session to Fable5 Max). `func_8014E048` (143 ins, reach-134; "S11 LUID⊗alloc intrinsic / not source-steerable" since the map wave; **28-off even after T5's directed permuter**) → **MATCH (143/143) + whole-binary BANKED** (`harvest_verify` 1/0, ov_SC01_077 `d19c9580…`). Derived by reading gcc-2.7.2 source + `-dl -dg -dS` RTL dumps (12 experiments, `.run/gccmap/exp/e1a..e1k.c`): **S12 reused-s32-temp fence** (output/anti deps forbid load batching; **u16 temps DON'T work** — unpromoted HI vars spawn per-use zext temps that combine folds away), **S13 head-skip escape** (body-local param copies keep hard arg regs live into the temp windows → conflict-steer the scratch contest; zero-byte volatile-asm dead-read as a wedge-slot fence; multi-input dead-read to rebalance K2 densities), **cse-opaque asm-copy** (`addu %0,%1,$zero`) for must-materialize pointer copies, **RC-4b pinned store-temp**, **RC-10 preference-cascade mechanics** (set_preference one-level expression unwrap; expand_preferences dying-into-set merge; find_reg pass-0 used-so-far/someone-prefers + pref override). Integration needed 2 hand-reconciles (both T6 classes): engine_core.h:17569 caller-decl `s16*`→`u16*` (ptr param type codegen-neutral) + canonical data decls with `*(u16*)` access casts (D_801152A8 `u8[]` / D_801152AC `s16`). **×134 lift blocked by dedup_propagate self-containment (pins/asm) → T6 target** (joins func_80132784). Distilled (R30): sched.md **§6/S12/S13** + regalloc.md **§F/RC-10** + cookbook §31 triage-table **S11 downgrade**. Backlog re-logged (capped). R22 clean fleet check-all running at close. Commit: (checkpoint).
 - **T5 ✓ (2026-07-03):** **§31-directed permuter mutation + grinder input-changed gating — built, validated, distilled.** NEW `tools/permuter_weights.py`: `classify(klass,where)` → `regalloc|schedule|cse|None` + `render_settings_toml` emitting the `[weight_overrides]` table decomp-permuter merges over the gcc defaults (`main.py:336` / `helpers.py:merge` — per-key REPLACE; **no submodule edit**, R3/R20). Biases pass-selection toward each class's §31 levers (`perm_reorder_decls` RC-1/3 · `perm_reorder_stmts` RC-2/S1 · `perm_temp_for_expr` S2 · `perm_commutative` cse) and pushes the value/type noise to ~0.1. Wired into `p16_permute.setup(…, klass=, where=)` (+`--klass`, backlog auto-lookup) and `grinder.py` (auto-threads `klass`/`where_stuck`; `klass=None` → gcc defaults = the pre-T5 undirected search, a safe superset). **Grinder fix (R14):** replaced the blind `tried.clear()` idle churn with **input-changed gating** (`draft_sig`=(best_draft mtime, closeness) — re-open a fn only when the worker improved it; the permuter is deterministic given base.c+target.o). **VALIDATED:** the regalloc profile drove `func_8014E048` base masked-36 → **29** (match_one `-drz` **35→28**) where the undirected search stalled — real directed progress; re-logged (closeness 28, improved draft promoted). The 4 flagship count-exact seeds are the project's WORST-CASE intrinsic S11/RC-6 walls ("C-space discontinuous" §31 RC-6) — directed mutation improves but doesn't gate them → T5b/backlog fuel (§31 "two probes, don't grind"). Distilled: cookbook **§3b** + SETUP inventory (R16/R30). **No build-input changed → 136/136 fleet invariant untouched (tools/docs only).** Commit: (checkpoint).
