AgentXchain v2.155.4

v2.155.4 is a dogfood unblock patch over v2.155.3. It fixes the idle-expansion acceptance contract exposed by the tusq.dev dogfood branch: PM produced a valid structured idle-expansion-result.json sidecar, but the acceptor only looked for top-level turnResult.idle_expansion_result.

Bug Fixes​

  • BUG-64 idle-expansion sidecar acceptance: accept-turn now loads a sibling .agentxchain/staging/<turn>/idle-expansion-result.json for required vision_idle_expansion turns when turn-result.json does not contain top-level idle_expansion_result.
  • Canonical normalization preserved: dogfood-observed sidecar fields such as proposed_intent and string vision_traceability are normalized into the canonical idle_expansion_result contract before validation. The canonical validator still rejects missing or malformed idle-expansion output.

Evidence​

  • cd cli && node --test --test-timeout=60000 test/turn-result-validator.test.js test/beta-tester-scenarios/bug-60-perpetual-idle-expansion.test.js -> 107 tests / 21 suites / 0 failures / 0 skipped

Tester Re-Run Contract​

Run the shipped package:

npx --yes -p [email protected] -c "agentxchain --version"

For BUG-64 closure, resume the tusq.dev dogfood branch and quote:

  • the same PM idle-expansion turn can be accepted without manually editing turn-result.json
  • .agentxchain/staging/<turn>/idle-expansion-result.json is normalized into accepted history as idle_expansion_result
  • idle_expansion_ingested fires with payload.kind == "new_intake_intent"
  • the continuous session advances beyond the BUG-64 paused state

For regression proof, quote that a required vision_idle_expansion turn with neither top-level idle_expansion_result nor sibling sidecar still fails schema validation.

For downstream closure, start from a clean checkpoint and quote:

  • functional downstream behavior remains fixed: continuous does not idle out in QA, QA advances, launch_ready unblock completes the run, and no duplicate dispatch occurs
  • quote any startup_latency_ms, elapsed_since_spawn_ms, and runtimes.<id>.startup_watchdog_ms evidence relevant to adapter-path reliability while confirming the downstream flow still uses the real runtime path
  • after final terminal approval, status is completed, pending_run_completion=null, and active_turns={}
  • durable events include both gate_approved for run_completion and run_completed
  • non-terminal phase recovery should still quote phase_entered with reconciled_before_dispatch if a standing gate advances before dispatch
  • .agentxchain/continuous-session.json no longer stays at paused with runs_completed=0; quote the terminal session shape after the run completes
  • session_continuation should still be quoted if the continuous session chains into another run; otherwise quote the terminal reason instead

For BUG-55 regression proof, continue using accept-turn followed by checkpoint-turn and quote verification.produced_files, undeclared_verification_outputs, and git status --short.

Clean tree means BUG-55 is fixed for your reproduction.
