Research direction
Read docs/internal/2026-07-18-trace-golden-e2e-technique.md and the packages/opencode/test/altimate/trace-golden/{normalize,match,driver}.ts entry points first. Then inspect the scenarios and confirm that scripted headless-session traces are normalized and partial-order-matched against committed goldens. Done means coverage of the stated S5 native/plugin parity and S7 continuation invariants without product changes or treating tracing as an S3 security oracle.
Written by the indexing model from the issue text.
Description
Novel e2e technique: drive a real headless session with a scripted model, capture the emitted trace, normalize (allowlist projection), and partial-order-match against a committed golden. Codex-scoped to S5 observable native/plugin parity + S7 continuation invariants (NOT an S3 security oracle — tracing is failure-suppressing). Files: packages/opencode/test/altimate/trace-golden/{normalize,match,driver}.ts + scenarios. Technique doc: docs/internal/2026-07-18-trace-golden-e2e-technique.md. Test/infra only, zero product changes.
