AgentXchain v2.121.0

Released: 2026-04-17

Highlights​

Orchestrator State Files Allowlist Fix​

Fixed a governance correctness bug that blocked every review_only role in continuous mode from completing a single turn. The orchestrator-owned state files .agentxchain/continuous-session.json, .agentxchain/human-escalations.jsonl, and .agentxchain/sla-reminders.json were missing from the ORCHESTRATOR_STATE_FILES allowlist, causing false-positive artifact mismatch rejections.

Root cause: When the continuous engine created the session file before the first turn dispatch, the acceptTurn() governance check saw it in the git diff and blamed the review_only role for "modifying product files." This class of bug is only detectable by full end-to-end proof in a fresh project — every mock-based E2E missed it because fixtures start with a clean baseline.

Export/Restore Continuity Preservation​

Orchestrator-owned runtime state that affects blocked continuous recovery is now preserved by both agentxchain export and agentxchain restore. Previously, an operator could run continuous mode, hit a blocker, export the workspace, restore on another checkout, and silently lose the exact recovery state the runtime depends on.

Files now preserved:

  • .agentxchain/continuous-session.json — continuous session state, budget, runs completed
  • .agentxchain/human-escalations.jsonl — structured human escalation records
  • .agentxchain/sla-reminders.json — SLA reminder state

Live-Adapter Dogfood Proof​

First real-model continuous mode proof using Anthropic Haiku 4.5 via the api_proxy adapter in a temp governed project. The proof dispatched 16 real API calls, all accepted by governance, with correct budget tracking ($0.208 spent) and truthful session state. This is the first time the product has been proven end-to-end with a real model producing real artifacts — not just mock-based E2E tests.

Lights-Out Operator Runbook​

New cohesive operator guide (/docs/lights-out-operation) covering the full repo-local lights-out lifecycle: preflight, bounded proof run, daemon launch, session observation, blocked recovery, priority injection, budget stops, and SIGINT behavior. Previously, operators had to reconstruct the lifecycle from scattered per-feature docs.

What Changed​

  • Orchestrator state allowlist: added continuous-session.json, human-escalations.jsonl, sla-reminders.json to ORCHESTRATOR_STATE_FILES (DEC-ORCHESTRATOR-STATE-FILES-001)
  • Export/restore continuity: all three orchestrator state files now round-trip through export and restore (DEC-CONTINUITY-EXPORT-001)
  • Live dogfood proof: first real-model continuous mode execution with Anthropic API (DEC-LIVE-DOGFOOD-001)
  • Lights-out runbook: dedicated operator guide for repo-local continuous operation (DEC-LIGHTS-OUT-DOCS-001)

Evidence​

  • 5,478 tests / 1,152 suites / 0 failures
  • Website build: clean
  • Live dogfood: 16 Anthropic API calls, $0.208 spent, all turns accepted by governance
