From 8301ade4a02432065ca3eeb1f0bafe7b436088bb Mon Sep 17 00:00:00 2001 From: "Derek J. Russell" Date: Fri, 24 Apr 2026 23:29:12 -0700 Subject: [PATCH] docs(wave3-parallel-dispatch): record S1b cadence + promote block class MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per operator binding 2026-04-25 (Option B closure of F1 Slice 4 cadence): "lock in S1b as the cadence record. The F1+F2 plumbing is definitively proven end-to-end. ... The internal architecture is mathematically sound." S1b session bt-2026-04-25-054256 (MERGE_HEAD b068c8a083) was the first ever live battle-test in the entire W3(6)+F1+F2 arc to fire all three integrations simultaneously: - F1: 8 [IntakePriority] primary dequeue markers, 0 priority_inversion - F2: 3 envelope_routing_override markers - Seed routed STANDARD via priority-0.5 clause (was IMMEDIATE in S1a without F2) - Extended blocklist clean (0 traceback frames in parallel_dispatch.py / worktree_manager.py / phase_runners/ / phase_dispatcher.py) - session_outcome=complete, stop=idle_timeout, 1510s, $0.16 Block class promoted from `intake_priority_inversion` (W3(6) S1+S2+S3, 2026-04-23/24) → `provider_exhaustion` (S1b, 2026-04-25). Structural intake failure mode FIXED; downstream provider transport (anthropic_transport infra waiver) is the new gate. Cadence PAUSED at 1/3 sessions — Slice 5b default flip remains blocked, F1 Slice 4 default flip remains blocked. Operator-rejected unblock paths: modifying the seed (Option C) or inflating timeout boundaries (Option D) — both would mask the issue, not fix it. This commit updates the runbook only; no code changes. Full evidence record in memory/project_wave3_item6_graduation_matrix.md §"F1 Slice 4 cadence S1b — live_reachability=blocked_by_provider_exhaustion".
