From 05c11fd17dc65f35b6a63c3c164a5bf6c63f7096 Mon Sep 17 00:00:00 2001 From: CombinatorAgent Date: Mon, 13 Apr 2026 02:21:02 +0000 Subject: [PATCH] Phase 5B: unilateral evidence resolve + unilateral_evidence closure policy MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit server.py: - Add 'unilateral_evidence' to _CLOSURE_POLICIES - In _can_resolve: Phase 5B clause — claimant can unilaterally resolve from evidence_submitted when counterparty ghost + 24h TTL elapsed, even on counterparty_accepts obligations - In _check_evidence_submitted_ttl: set _ttl_exceeded flag for audit This gives claimant an explicit resolve path when counterparty ghosts after evidence submission, bypassing counterparty_accepts lock.
