The main probe (8 drafts) ran 38 minutes without a verdict. Two defects, neither about the drafts: 1. FIXED — the compile-error shortcut matched only 'previous declaration of', but gcc printed 'previous implicit declaration of func_80017930'. So a batch whose culprit gcc had already named fell through to bisection, which costs a full clean EXE rebuild per step. The matcher now accepts the implicit and conflicting-types forms too. (resolve_conflicts is separately blind to this class: an implicit decl comes from a call site with no prototype.) 2. NOT FIXED, documented — the typedef-hoist repair is not idempotent. It emitted 'hoisted 2 typedef(s)' 150 times and left a duplicated marker comment; it re-hoists, rebuilds, fails identically and repeats, so it cannot converge. Make it idempotent and bound the bisect before gating main again. Also: ox_campaign pre-draws the next wave AFTER launching shards (doing it before left the fleet at 8 agents while a card job ran), collect_drafts grants stragglers a grace period instead of letting 2 of 220 shards idle the fleet for 34 minutes, and drafter bands are now mostly full-range (the 400-2000 band drew 9 cards for a 2,000-worker fleet).

main gate — two defects found by the P31 S58 probe (2026-08-24)
Probe: 8 main drafts from .run/main_queue/an.json through tools/gate_main.py --apply.
Outcome: killed after 38 minutes without a verdict. Neither defect is about the drafts.
1. The compile-error shortcut missed the error gcc actually printed — FIXED
gate_main documents "A COMPILE error names its own culprit -- read it instead of bisecting.
Bisection here costs a FULL CLEAN REBUILD per step (~2-4 min), so it is worst-case hours."
Its matcher recognised only previous declaration of. gcc printed:
src/800.c:3018: warning: type mismatch with previous implicit declaration
src/800.c:2910: warning: previous implicit declaration of `func_80017930'
so the batch fell through to bisection to rediscover a symbol already named in the first build.
Fixed: the matcher now also accepts previous implicit declaration of and conflicting types for.
An IMPLICIT declaration comes from a CALL SITE with no prototype, which is also why
resolve_conflicts reported 8 -> 8 compatible, 0 dropped — it compares draft-vs-draft and
draft-vs-explicit-decl, and is structurally blind to this class. That pre-check gap is NOT fixed.
2. The typedef-hoist repair is NOT IDEMPOTENT — NOT FIXED
Every bisect round emitted:
hoisted 2 typedef(s) to the top of src/800.c: Poly12Obj, Poly12Pt
150 times, and the working-tree diff at kill time was a DUPLICATED marker comment:
/* hoisted by gate_main so drafts above can reuse them (§181) */
+/* hoisted by gate_main so drafts above can reuse them (§181) */
The repair does not detect that it has already run, so it re-hoists, rebuilds, fails identically, and repeats — it cannot converge. This is why the probe never produced a verdict.
Before main is gated again: make the hoist idempotent (detect the marker / the existing typedef) and bound the bisect by iteration count so a non-converging repair fails loudly instead of spinning.
