From a8080d3fd4d994004689148113c6fe831364d7d8 Mon Sep 17 00:00:00 2001 From: "Derek J. Russell" Date: Sun, 17 May 2026 20:46:32 -0700 Subject: [PATCH] =?UTF-8?q?fix(governance):=20R1=20=E2=80=94=20COMPLEX=20o?= =?UTF-8?q?uter/inner=20timeout=20coherence?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Soak bt-2026-05-18-015317: psf routed COMPLEX (Trace-1 validated) but GENERATE died with CancelledError at ~255s — the OUTER Iron-Gate _gen_timeout for COMPLEX (JARVIS_GEN_TIMEOUT_COMPLEX_S=240 + JARVIS_OUTER_GATE_GRACE_S=15 = 255s) killed the call BEFORE the INNER fallback's 360s thinking window could complete. More COMPLEX budget on the inner path is moot if the outer gate fires first (same class as Task #88b, now on the COMPLEX+SWE-bench path). Falsifies the earlier "timeouts resolve with COMPLEX budget" assumption — empirically. Root fix — single source of truth, no duplication, no per-path drift: * candidate_generator: extract the inline _call_fallback thinking predicate + cap into module-level gen_call_likely_thinking() + fallback_thinking_cap_s(); refactor _call_fallback to consume them (behaviour-identical for _max_cap; removed locals have zero downstream refs). * generate_runner (the LIVE phase-dispatcher path) + orchestrator (dead-twin parity): at the _gen_timeout birth seam, BEFORE the deadline the outer wait_for derives from, floor _gen_timeout = max(_gen_timeout, fallback_thinking_cap_s()) when gen_call_likely_thinking(route, task_complexity). Both inner and outer now consume the SAME predicate+cap → outer >= inner holds by construction. Floor runs BEFORE adaptive scale_gen_timeout (also added to generate_runner for orchestrator parity) so one coherent value propagates to deadline + outer wait_for + tool-loop budget. Fail-open to route base; lazy import (no module-load coupling). Spine: tests/governance/test_r1_timeout_coherence.py (14 — predicate truth-table incl. case-insensitive + psf case; cap default/env/invalid -fallback; coherence invariant max(240,360)>=360 (>255 death point); AST pins: candidate_generator uses shared helper not inline literal; generate_runner + orchestrator floor BEFORE the GENERATE deadline they feed and BEFORE adaptive scale; no duplicated predicate on either path). 52 adjacent parity tests green (route/classify runner parity + op-isolation). 18 candidate_generator TestExhaustionInstrumentation failures are PRE-EXISTING (stash-isolated: identical on clean origin/main) — flagged, not bundled, per clean-scope discipline. R2 (controlled rubric soak: serial, urgency=high, sensor-throttled) runs after this merges. Tasks #7/#8 stay ratified-held.
