From 6d76111a169d442bf4dc2b6e7686be04626680fd Mon Sep 17 00:00:00 2001 From: weichen Date: Thu, 8 Oct 2026 00:34:46 +0000 Subject: [PATCH] Add leader progress ledger, replan cap, and mailbox with actor attribution (Q2 WP2) Why: Q2 acceptance requires leader runs to detect stuck delegation loops and cap replans instead of spinning to the turn limit, and a mailbox primitive whose messages can never resolve a pending permission approval (acceptance 3). Evidence: squad conformance tests (leader_mailbox_conformance_test.go): ledger stuck->replan, replan cap finalize, mailbox delivery after hold, mailbox-cannot-approve-permission (structural + actor second defense), post guards; full suite green with -race. Impact: LeaderState gains Progress/StuckTurns/Replans/MaxReplans/ReplanNote (persisted in leader.json); RunState gains Mailbox (persisted in runstate.json); RespondDecision gains Actor - non-human actors are rejected on choice gates; step briefs and leader task briefs include pending mail.
