Coldkeep v1.12.3 — Release Train Closure Hygiene

Coldkeep v1.12.3 is a hygiene-only patch release that closes the v1.12 release train cleanly before starting v1.13.

This release does not change product behavior. It focuses on release documentation accuracy, generated validation artifact cleanup, and a clean handoff into the next engine/catalog stabilization phase.

Highlights

• Corrected stale v1.12 release-train documentation status.
• Preserved deferred v1.12 operations as explicitly deferred.
• Added a clear v1.13 handoff note.
• Removed generated local benchmark/regression validation artifacts from the repository root.
• Added ignore rules to prevent future generated validation outputs from being committed accidentally.
• Preserved intentional benchmark baseline files.
• Recorded final v1.12.3 hygiene release-gate evidence.

Release-train documentation cleanup

The main v1.12 release-train documentation now reflects the actual released state of the v1.12 line.

Updated documentation no longer describes v1.12 as planning, in progress, pending, or not ready.

The release docs now correctly state that the scoped v1.12 train is complete/released while keeping intentionally deferred operations clearly documented.

Generated validation artifact cleanup

Generated local benchmark and regression validation outputs were removed from the repository root.

The following generated outputs are no longer tracked:

• benchmark-none-w1.json
• benchmark-none-w4.json
• benchmark-zstd-w1.json
• benchmark-zstd-w4.json
• regression-report-none-w1.json
• regression-report-none-w4.json
• regression-report-zstd-w1.json
• regression-report-zstd-w4.json

Ignore rules were added so future local pre-release validation runs do not accidentally commit these generated outputs again.

Intentional benchmark baseline files were preserved.

v1.13 handoff

With v1.12.3 complete, the v1.12.x line can be considered closed.

The next release train should be v1.13, focused on:

• engine contract stabilization;
• catalog contract stabilization;
• error taxonomy;
• dependency-direction checks;
• engine-level correctness invariants.
