Kinneyzhang 04a16eeb18 merge: reconcile retained-root metadata and unmount coverage
Integrate 127aa7a with the newer property-specific Host contract from 805323a. Preserve owned role and ARIA checks, callback and Behavior composition, and caller overrides for ordinary metadata. Carry the historical live-buffer unmount assertions into the current render-port revision test. Regression execution was waived; syntax and diff checks passed.

Historical worktree integration

The September 5 benchmark worktrees contain competing repair attempts against an earlier ETAF contract. Their changes were reconciled against current main on September 8, rather than replacing the newer implementation.

  • 127aa7a preserves every existing root metadata value. Current main's 805323a already protects owned role and ARIA semantics, composes callbacks and Behaviors, and allows caller values for ordinary metadata. Retain that more precise implementation when reconciling the old attempt.
  • a206cfd changes only the old metadata docstring to describe unrestricted caller overrides. Retain the current docstring because owned semantic conflicts are now rejected explicitly.
  • The retained-root fixture's instance-scoping test is already present in tests/etaf-component-frontends-tests.el. Its old role-override expectation conflicts with the current owned-role contract and is superseded by the existing rejection assertion.
  • The three v1 unmount test attempts exercise the same lifecycle outcome. Production no longer exposes the v1 fallback. Their live-buffer, unmounted, zero-revision assertions are carried into the current render-port revision contract test.
  • The metadata baseline deliberately rejects every duplicate metadata key; that blanket rule is superseded by the current property-specific policy.
  • The missing-revision baseline deletes an old v1 test. Both that test and the v1 production route have already been removed by the current SPI boundary.

The historical worktrees remain as evidence. They are not runtime dependencies. Regression execution was explicitly waived for this integration; static checks do not establish fresh behavioral or performance acceptance.
