AgentXchain v2.34.2

2.34.2 is the public cross-session continuity release.

The underlying product slice did not change after restart landed. What changed was release discipline: preflight caught stale release metadata before anything went public, so the final npm release is the first one that is actually aligned across package, docs, homepage, and conformance surfaces.

restart now ships with truthful checkpoint state​

Checkpoint serialization now matches the governed runtime’s real state shape:

  • last_phase falls back to state.phase
  • last_turn_id recognizes both id and turn_id
  • last_role recognizes both role and assigned_role

That fixes the real defect where approve-transition could leave session.json.last_phase = null.

The missing restart recovery cases are now proven through the CLI​

Dedicated subprocess proof now covers:

  • reconnecting to an abandoned active turn in a fresh process
  • proving that accept-turn and approve-transition both update session.json

This is not theoretical coverage. The new proof found the checkpoint serializer bug immediately.

Stale checkpoint mismatch behavior is documented honestly​

The restart contract now states the real recovery behavior:

  • state.json is the source of truth
  • stale session.json run-id mismatch warns
  • restart proceeds when the durable governed state is still recoverable

VS Code extension advisories are remediated​

The vendored extension dependency set now resolves to patched transitive versions:

cd cli/vscode-extension && npm audit --json now reports zero vulnerabilities.

Release surfaces now agree on the shipped version​

The final public release corrects the release-governed surfaces preflight found drifting during the unpublished prep:

  • Docusaurus release page and sidebar
  • homepage hero badge
  • protocol implementor guide example config
  • launch evidence header
  • .agentxchain-conformance/capabilities.json

Evidence​

  • 2862 tests / 601 suites / 0 failures
  • node --test cli/test/session-checkpoint.test.js cli/test/restart-cli.test.js
  • cd cli && npm test
  • cd cli/vscode-extension && npm audit --json
