chore(models): review lifecycle proposal 85f3b4a3a32a

[github-actions]

This draft carries sanitized model-family and deprecation evidence. It has no activation authority and does not deploy, promote, or swap a live mapping. Compatibility impact and the exact proposal digest are recorded in the added manifest.

Reviewed on 2026-09-12. The proposal remains intentionally draft: the manifest is proposal-only and carries no activation, mapping, execution, or live-execution authority. Focused validation passed (32 passed in tests/integration/scripts/test_model_resolution_lifecycle.py). No merge or deployment action is authorized by this record; retaining the draft preserves the reviewable lifecycle evidence.

Reconciled again during the open-PR review on 2026-09-15.

Retain this PR as an intentional proposal-only draft. No new reviewer decision, activation approval, mapping authority, execution authority, CI evidence, or deployment authorization has appeared since the 2026-09-12 review. The existing 32 focused lifecycle tests support the manifest mechanics only; they do not authorize merge or activation. No branch update, merge, close, deployment, or live model action was performed.
