- family_sweep §53 INTERLOCK (the Task-3 deliverable): a has_mid_jr family CANNOT bank through the
carve-less --hseq path — its exemplar's own bank needed a jump-table carve. The sweep now SKIPS them
LOUDLY, names the right tool (jtbl_family_bank), and states that a 0% from this path is a TOOL
ARTIFACT, not a wall. Uses the manifest's has_mid_jr (family_hseq already derived it — R33, one
oracle, shared with dedup_extend; no re-derivation). --allow-jr is the escape hatch.
WHY: a silent 0% from the wrong tool is exactly what manufactured the Phase-26 "structural families
≈0% / don't template" doctrine and steered two phases of strategy (§53, Phase-28 T1). The interlock
makes the omission impossible to misread.
VERIFIED (live-fire + negative control, R32/R35): manifest carries 11 has_mid_jr families / 163
member-slots of 1418 sweepable; --band substantial -> skips 9 families / 155 slots (159 -> 150
families); --allow-jr -> 159 (does NOT skip). It correctly flags 0x8017bebc (n=115) = B2, the very
family whose missing carve produced the ≈0% doctrine (0/8 -> 102/115 once carved).
- worker_wave.js: pass --o0 to the match_one self-check for -O0 targets (new `o0` target flag) + an
-O0 prompt block (§18/§18-P29: the %lo-fold residual and the array-of-struct crack). Without it an
agent iterates a -O0 target against an -O2 compile and can NEVER match — the same wrong-build-step
trap that produced the Phase-28 "~3%" swing number (Task 1). Exercised live by func_8013C414.
- byte-neutral: tooling only, no src/config touched.
- worker_wave.js: derive match_one self-check --asm-subdir per-target from t.asm
(was hardcoded main subdir -> every _a agent self-check crashed on missing .s ->
blind drafting). Enabled the 16/24 close rate on the _a measurement wave.
- CURRENT_PHASE cont.4: the _a vein is x134 (10/11 propagate byte-identical), not the
cont.3/§24 x1 wall. The gate's propagated:0 was 2 bugs: dedup_propagate all-or-nothing
batch-revert poisoned by 1 stale -O0 overlay-local straggler (func_8013C360), and
gate_stage sh() swallows dedup_propagate's non-zero exit. Realized +0.39% (commit:0267).
- residual class travels with the draft: drafter stamps // @class / // @stuck; gate_stage logs
the worker's gcc-quirk class to the backlog (not the coarse manifest class).
- wave_targets.py --class <C> / --list-classes: class-grouped re-attempt waves over the backlog's
classified near-misses (REGALLOC/SCHEDULE/REMAT/STRUCT/IV/LOOPGUARD/LOOSE/PLUMBING).
- orchestrator prep: auto-picks a class-focused wave when a class accrues >= threshold near-misses,
else a fresh pool harvest; clears the draft dir per wave.
- tools/workflows/distill.js: post-wave agent extracts NEW byte-verified gcc idioms -> cookbook §21
(R16, conservative); drafters now read the LIVE cookbook so distilled idioms feed forward.
- runbook: the full prep->worker->gate->distill cycle (the Phase-18 close-rate loop, automated).
- tools/workflows/worker_wave.js: parallel toolkit-aware drafter agents (xHigh) per target,
each writes its best matching C to the drafts dir (gate run by the orchestrator after).
args parsed robustly (harness may serialize to a JSON string — §20 gotcha).
- tools/wave_targets.py: select a wave batch from the fuel manifest (pool/region/N, skips
backlog walls). tools/grinder.py: token-free permuter grinder — permute backlog near-misses
-> gate_stage -> bank; STOP/heartbeat, idles for new worker near-misses, supervisor-friendly.
