AgentXchain v2.120.0

Released: 2026-04-17

Highlights

Continuous Failure Recovery Hardening

Continuous mode now classifies governed-run outcomes by state-machine truth instead of naive return completion. This fixes three state-machine bugs that could corrupt session accounting or permanently kill recoverable sessions.

Fixes:

• priority_preempted no longer increments runs_completed or resolves the executing intent
• Blocked governed results pause the session based on governed state truth, not only top-level stop reason
• Non-blocked executor failure marks the continuous session failed and leaves the intake intent executing
• Failed runs still contribute visible budget_status.spent_usd to the session accumulator

Paused-Session Re-Entry Guard

A paused continuous session no longer re-enters the intake pipeline on the next daemon poll. Previously, a recoverable paused session would be permanently killed because the continuous loop tried to start new work against a blocked governed state.

Behavior:

• If session is paused AND governed state is still blocked: return still_blocked, session stays paused
• If session is paused AND governed state is unblocked: resume session with direct executeGovernedRun() continuation (skip intake pipeline)
• The daemon keeps polling paused sessions without destroying them

SIGINT Semantics Fix

First SIGINT in executeGovernedRun() now means "finish current in-flight work then stop" instead of "abort the active dispatch and convert operator stop into retries exhaustion." Hard abort remains second-SIGINT behavior.

Multi-Schedule Continuous Coexistence

Sibling continuous.enabled schedules are now excluded from the normal runDueSchedules() path during daemon operation. Previously, a sibling continuous schedule could leak into the normal due-run lane on the same poll, violating the daemon's session ownership model.

Selection order (unchanged):

1. Active non-terminal schedule-owned session owner
2. First due continuous schedule in declaration order
3. No continuous schedule advanced on that poll

What Changed

• Continuous failure recovery: outcome classification by state-machine truth instead of naive completion (DEC-CONT-FAILURE-001)
• Paused-session guard: prevents re-entry into intake pipeline for blocked sessions (DEC-CONT-PAUSED-GUARD-001)
• SIGINT semantics: first SIGINT finishes current work, second SIGINT hard-aborts (DEC-RUN-SIGINT-001)
• Multi-schedule coexistence: sibling continuous schedules excluded from normal due-run path (DEC-SCHEDULE-CONTINUOUS-003)
• Daemon failure E2E: AT-SCHED-CONT-FAIL-001 proves block/unblock lifecycle through full daemon subprocess
• Multi-schedule E2E: AT-SDH-011 proves two continuous schedules coexist correctly
• Docs updated: recovery docs cover paused-session guard and continuous blocked-vs-failed behavior
• 5,470 tests / 1,150 suites / 0 failures
