PROPAGATION (§55b, its own targeted batch): dedup_propagate --addr 0x80141B90 --recover -> "138 overlays byte-identical after propagation"; 117 remaining stubs -> 0; 1 new dedup group. This was the ONLY one of the 21 directed-run banks worth propagating. THE REPRICING (R14 — measure a bucket's VALUE, not just its conversion rate): the directed run converted 27% (21/77) but moved the fleet ~0.03pp, because h_exact reach of the 21 is: func_80141B90=138, TEN at reach-1 (nothing to propagate), rest 2-10. Instruction-weighted, the ENTIRE permuter bucket is worth ~0.36pp at 100% conversion. The mechanism is validated; the fuel was small. Priced frontier (ins-weighted / 13.08M): LENGTH-DRIFT |d|<=2 472,178 ~3.6pp (339 fns) <- the real permuter-adjacent lever integration 419,162 ~3.2pp (305 fns) <- Task 14's ladder WIDTH 71,593 ~0.55pp (45) permuter (current) 46,571 ~0.36pp (74) BRANCH-POLARITY 9,462 ~0.07pp (22) So WIDTH/BRANCH-POLARITY are NOT worth prioritizing; my earlier "~200 candidates" framing undersold LENGTH-DRIFT 10x and oversold WIDTH. NEW: permuter_weights._LENGTH profile (perm_temp_for_expr/perm_expand_expr are the only passes that change instruction COUNT; the reorder/decl-order levers that dominate the regalloc+schedule profiles cannot, so they are down-weighted here) + residual_class ._drift_route (|d|<=2 -> permuter/`length`, larger stays structural — same class, opposite tool) + classify() accepts a PROFILE NAME directly (the measured profile beats re-parsing a free-text label). 17 unit tests green. grinder: --profile filter (probe ONE residual class's conversion) + a PERSISTENT attempt ledger. `tried` was in-process only, so every fresh --once run re-permuted the previous run's losers — the permuter is deterministic given (base.c, target.o), so that CPU can never produce a new win. Measured: a 20-target probe drew 19 already-tried targets. Keyed by draft_sig so an improved draft legitimately re-opens the function.
