AgentXchain v2.155.39

v2.155.39 fixes BUG-88 from DOGFOOD-100: the governance export writer was crashing with "Invalid string length" on large accumulated dogfood state. The fix adds maxExportFiles (500 cap with priority ordering), maxTextDataBytes (128KB text truncation), and fallback-safe serialization in run.js. The export verifier now also accepts truncated text entries (not just JSONL).

Bug Fixes​

  • BUG-88 export writer Invalid string length. buildRunExport() now accepts maxExportFiles (default 500) with priority file ordering and maxTextDataBytes (default 128KB) for text truncation, preventing RangeError: Invalid string length on large accumulated dogfood state. Files are priority-ordered so governance-critical artifacts are retained when the cap is reached.
  • Export verifier truncated text acceptance. The export verifier now accepts truncated text entries in addition to JSONL, so bounded exports with text-format truncation metadata pass verification instead of being rejected as invalid.
  • Fallback-safe serialization in run.js. The run command now retries serialization with tight-bound constraints on Invalid string length, preventing unrecoverable crashes during export write.

Tester Re-Run Contract​

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

For BUG-88: run agentxchain report --input <large-export.json> --format markdown on an export from a long continuous session (500+ files in accumulated state). The command must succeed without Invalid string length. Verify that the export contains truncation metadata for oversized text entries and that the file count does not exceed 500.

Carry-forward tester checks for shipped-package closure proof:

  • BUG-54 startup watchdog evidence should quote startup_latency_ms, elapsed_since_spawn_ms, and runtimes.<id>.startup_watchdog_ms.
  • BUG-55/87 verification-output evidence should quote undeclared_verification_outputs, verification.produced_files, and git status --short after accept-turn followed by checkpoint-turn. Clean tree means BUG-55 is fixed for your reproduction.
  • BUG-52/53 continuous recovery evidence should quote phase_entered, reconciled_before_dispatch, and session_continuation.
