Note

Overview
This is a Release Please cut that bumps versions across the monorepo (manifest, pyproject.toml, embedded __version__, and per-package CHANGELOG.md entries)—no application logic changes in the diff itself.

It publishes launchdarkly-ai-server 0.4.0 and launchdarkly-ai-python 0.3.0, with handler packages on matching minor/patch versions. Notable breaking note in the changelogs: evaluations from code are now explicitly experimental. Shipped capabilities called out for this release include configure() for SDK defaults, a shared AG-UI handler stream reader, AG-UI text/tool event emission for OpenAI, LangChain, and Claude handlers, OpenCode agents 0.1.1 (handler + AG-UI subset), plus fixes for native graph span LaunchDarkly identity and Claude agents runs that incorrectly succeed when the CLI reports an API error.

Holding this release:

1. PR is stale. The last release-please run (38775143699 on 7677621a) failed with a GitHub API timeout, so this branch is still based on fc08e8c3 and is missing #162 (opencode-agents AG-UI subset). Merged now, #162 would ship in opencode-agents 0.1.1 with no changelog entry. Re-run the workflow and confirm #162 shows up.
2. launchdarkly-ai-opencode-agents has never been published. PyPI returns 404 and there's no tag, so 0.1.1 is its first upload. Please confirm a PyPI pending trusted publisher exists for it before merging. JS Vercel failed the same way on npm.

The bumps look right: ai-server 0.3.0 -> 0.4.0 and ai-python 0.2.0 -> 0.3.0 for the #157 breaking change (minor because pre-1.0), and patches elsewhere.

Re-checked at the regenerated head. One blocker cleared, one left.

Cleared: the release-please refresh succeeded. opencode-agents 0.1.1 now lists #162 alongside #159, and #121 appears under Bug Fixes. The bumps are still right: ai-server 0.4.0 and ai-python 0.3.0 for #157 (minor, since pre-1.0), patches elsewhere.

Still blocking: launchdarkly-ai-opencode-agents has never been published. PyPI returns 404 and there is no git tag for it, so 0.1.1 would be its first upload. Please confirm a PyPI pending trusted publisher exists for it before merging. Without one the publish job fails, the same way the JS Vercel packages hit an npm OIDC 403. Minor: the changelog compare link points at a launchdarkly-ai-opencode-agents-0.1.0 tag that does not exist.
