Confidence Score: 4/5

The PR is not safe to merge yet because span stamping still misses AGENT_COMMIT_SHA loaded from .env.

Findings

1.  enable from environment runs once when code revision is imported. Normal worker startup imports register agent before EnvironmentVariables.refresh loads supported .env and .env.local files. A valid AGENT COMMIT SHA from those files reaches registration but never enables tracing. Run the hook after refresh, or read the value lazily. ▶

Fix with agent prompt

### Issue 1
src/agentex/lib/core/tracing/code_revision.py:undefined-124
`_enable_from_environment()` runs once when `code_revision` is imported. Normal worker startup imports `register_agent` before `EnvironmentVariables.refresh()` loads supported `.env` and `.env.local` files. A valid `AGENT_COMMIT_SHA` from those files reaches registration but never enables tracing. Run the hook after refresh, or read the value lazily.

For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.

Summary

This release makes agent build provenance automatic for tracing and registration. It also publishes both packages as version 0.27.0 and records the release notes.

• Stamps a valid AGENT_COMMIT_SHA on spans when the process starts.
• Sends the agent commit and cleaned source repository with registration metadata.
• Keeps secrets out of repository values by removing credentials, queries, and fragments.
• Updates package versions, manifests, generated version data, and changelogs to 0.27.0.
