The S45p9 blocker is closed, and the recovery loop that kept it from finishing is rewritten.
- BANKED: dedup_propagate --auto-from ov_SC02_037 --recover -> 29 functions propagated,
141 overlays byte-identical, dedup 1920 -> 1949 groups, member instances 246,284 ->
249,099 (+2,815). make clean && extract-all && check-all -> 213 passed / 0 failed (R22).
- WHY IT FINISHED THIS TIME: gate_all -> gate_failures returns EVERY failure from the sweep
that already computed them, and the recovery loop resolves them all per round. Converged in
3 rounds; the old one-overlay-per-sweep design needed ~138. That reframes the S45 run — it
was not nearly done when it died, it had barely started.
- Batching did NOT cost capability: per-overlay necessity probes excluded four of the nine
culprits from only the 9 overlays that needed it (not all 138), and ov_SC07_006 was
RECOVERED by the Part-B caller-extern reconcile instead of excluded.
- Plan phase parallelised: 5 min -> 26 s, plan + skip classification byte-identical. Its
compiles_standalone temp file is per-call now — the fixed `t.c` was the same fake-isolation
class as match_one's shared --work dir (P28 T5), latent until something ran it in parallel.
- docs/accelerators.md (NEW, Drew 2026-08-07): the reusable-workflow ledger — what we learned
late that a future decomp should know on day one, each entry with when we found it, when it
WAS findable, what it cost, and the honest prerequisite where one exists.
