What to build

Write the final pre-release closeout decision after API cleanup, docs/PRD/CHANGELOG alignment, targeted release-candidate smoke, packaged smoke, and TS/JS + Go Agent Sufficiency refresh are complete. The decision should classify the release candidate as release-ready, release-ready with explicit non-blockers, or blocked.

This issue should reference Phase 8 as prior evidence, not reopen it. It must not claim release execution, version bump, npm publish, tag creation, or GitHub Release workflow execution.

Acceptance criteria

• Decision cites API cleanup evidence.
• Decision cites docs, PRD, and CHANGELOG alignment.
• Decision cites targeted source-path and packaged release-candidate smoke.
• Decision cites TS/JS and Go Agent Sufficiency refresh evidence.
• Decision classifies the result as release-ready, release-ready with explicit non-blockers, or blocked.
• Explicit non-blockers are listed, including Post-PRD optimization tracker for Rust indexing performance #165 performance optimization unless separately completed.
• Decision states that no release workflow, npm publish, tag creation, or version bump was performed.
• Final decision artifact is written under docs/plans/.
• Tracker Rust-hybrid pre-release polish tracker #275 is updated with the final conclusion.

Completed in 08a2434. Closeout decision: proceed with the pre-release API polish complete, with the documented Go/Gin sufficiency caveat. Evidence links: docs/plans/2026-06-19-rust-hybrid-pre-release-closeout-decision.md, API cleanup evidence, smoke evidence, and Agent Sufficiency spot-check evidence. Validation: npm run build; targeted regression suite; full npm test (1834 passed, 15 skipped).
