What

Packages the agent e2e suite (conductor-ai-e2e/) into a self-contained, version-stamped tarball — conductor-ai-e2e-java-<version>.tar.gz — attached to every GitHub release, so downstream repos (e.g. orkes-io/orkes-conductor) can pin the e2e suite to the exact java-sdk release they run against. Replaces the agentspan-sdk-e2e-java-* bundles formerly cut from agentspan-ai/agentspan.

• conductor-ai-e2e/release/package-e2e-bundle.sh — stages the 26 suite sources + a standalone build.gradle pinning org.conductoross:conductor-ai:<version> from Maven Central (no SDK source vendored), the repo's pinned Gradle wrapper, run.sh, and a README. Unreleased SDKs can be tested via -PconductorAiVersion=X -PuseMavenLocal.
• conductor-ai-e2e/release/test-package-e2e-bundle.sh — static validator (file parity, version pin, no leftover placeholders, wrapper completeness; no network).
• .github/workflows/release-agent-e2e-bundle.yml — packages, validates, generates sha256 sidecars, and uploads to the release; same triggers as publish-release.yml, plus workflow_dispatch to attach bundles to existing releases (first target: v6.0.0.rc1).

Validation

• static validator green
• bundle compiles against conductor-ai/conductor-client published to mavenLocal at a throwaway version (proves the published POM exposes the full test classpath)
• full bundle run vs conductor-oss 3.32.0-rc.8: 136 executed / 0 failed / 2 known skips (Suite2 secret-write steps — read-only secret store)
• full bundle run vs orkes-conductor (embedded server + orkes-workers fleet): 134 executed / 0 failed / 4 capability skips (credentials need conductor-agentspan > 0.4.2)

Merged main and adapted to the module restructure (0413dab7: conductor-ai-e2e → e2e, conductor-ai → conductor-client-ai, suite env contract → CONDUCTOR_SERVER_URL/CONDUCTOR_AGENT_LLM_MODEL):

• release tooling now lives at e2e/release/; sources staged from e2e/src/test/java
• the bundle pins org.conductoross:conductor-client-ai:<version> (unreleased-SDK override renamed to -PconductorClientAiVersion)
• bundle run.sh/README speak the new CONDUCTOR_* env vars
• the tarball name stays conductor-ai-e2e-java-<version>.tar.gz — it's the downstream contract (orkes-io/orkes-conductor#3740)

Re-validated after the merge: static validator green, and the bundle compiles against conductor-client-ai published to mavenLocal at a throwaway version.

Note for downstream: bundles cut from this layout need CONDUCTOR_SERVER_URL (not AGENTSPAN_SERVER_URL) in the consuming CI env, and the first release carrying both the renamed artifact and the bundle asset will be whatever is tagged after this merges — the 6.0.0.rc1 pin downstream should be bumped to that.
