What is Different

Before

Scattered source updates, isolated context, and manual follow-up across multiple feeds.

Now

Adds a lifecycle fix so local workers are not reused across app-version boundaries, preventing stale in-memory/runtime state from being applied after an upgrade.

Why Track This

Why It Matters

Operators and developers upgrading Opencove are less likely to hit inconsistent runs after update, because local workers are prevented from reusing outdated state and are treated as fresh units for the new version. This appears to improve upgrade stability by isolating worker state transitions, so watch for first-start latency on update and verify that no stale worker IDs or cached sessions reappear in logs after repeated upgrades.

What To Watch Next

  • Watch whether local worker becomes a repeated pattern.
  • Track follow-up changes around Computer Use Agents.
  • Compare future signals against this evidence trail.
  • Re-check risk flags: upgrade_worker_state_contamination, stale_worker_reuse_regression.
