fix(review): retain the committed selector of a ready plain inspect

[Alan-TheGentleman]

Linked Issue

Closes #1501

PR Type

• Bug fix

Summary

• A plain inspect {baseRef, committedOnly: true} that resolves ready now retains {targetIdentity, candidateTree, baseRef, committedOnly} under the pre-lineage key, so the following plain START reviews exactly the inspected committed range instead of adopting the native default base-ref.
• RetainedPreLineageNativeUntrackedSelection makes its untracked fields optional; START adopts them only when the entry recorded an untracked decision, so the bug(review): intended-untracked submission drops explicit committed base selector #1192 submission path is unchanged.
• A candidate change between inspect and START is still refused (native-start-retained-selection-candidate-mismatch).

Changes

File	Change
extensions/gentle-ai.ts	Retain the ready-inspect selector; START reads untracked fields only when present
tests/review-controller-native-routing.test.ts	Ready inspect then START uses its base; a second ready inspect replaces the first; changed candidate refused
odd/tasks/review-ready-inspect-selector.md	Feature document with evidence

Test Plan

• node --experimental-strip-types --test tests/review-controller-native-routing.test.ts: 80 pass (RED before the fix: 77/80).
• node --experimental-strip-types --test tests/*.test.ts: 3900 pass, 0 fail, 43 skipped (Windows-only).
• node scripts/verify-package-files.mjs, node scripts/check-provider-contract.mjs: pass. node --experimental-strip-types tests/runtime-harness.mjs: exit 0. node scripts/check-types.mjs: no regressions.
• Native review (reliability lens): approved.
• Shellcheck: not applicable. Skills: not changed.

Summary by CodeRabbit

• Bug Fixes
  • A ready inspection now carries its committed-range selection into a subsequent start, including custom base references and committed-only selections.
  • A newer inspection replaces the previously retained range. Starting is prevented if the target or candidate tree has changed since inspection.

📝 Walkthrough

Walkthrough

A ready inspect with a canonical baseRef now retains its candidate identity and committed-range selector when it requires no untracked-selection decision. A later plain START can reuse that selector. Tests cover reuse, replacement, and rejection when the candidate changes.

Committed Selector Retention

Layer / File(s)	Summary
Capture selectors from ready inspect results extensions/gentle-ai.ts, odd/tasks/review-ready-inspect-selector.md	Pre-lineage retained selections can omit untracked-selection fields. A ready inspect without an untracked-selection decision retains its candidate identity and committed-range selector. The task document records the issue and scope.
Adopt retained selectors during START extensions/gentle-ai.ts, tests/review-controller-native-routing.test.ts, odd/tasks/review-ready-inspect-selector.md	START adopts retained untracked fields only when an untrackedScope exists. Tests cover selector reuse, replacement by a later ready inspect, and rejection when fresh STATUS reports a changed candidate. The task document records acceptance criteria and verification results.

Include the adopted base ref in the replay key.

When a consent-required plain START leaves a candidate view pending, a later plain START can adopt a different canonicalBaseRef while keeping the other replay-key fields and currentCandidateTree unchanged. createOrReuse then returns the earlier view because it looks up candidates by replayKey alone. If the selected bases have different trees, assertNativeStartCandidateBinding throws candidate-target-projection-drift instead of starting the newly inspected range.

🐛 Suggested fix

-const replayKey = JSON.stringify({ cwd: defaultCwd, lineageId: parameters.lineageId ?? null, input: parameters.input ?? null, inputPath: parameters.inputPath ?? null, candidateTree: target.projection.currentCandidateTree });
+const replayKey = JSON.stringify({ cwd: defaultCwd, lineageId: parameters.lineageId ?? null, input: parameters.input ?? null, inputPath: parameters.inputPath ?? null, canonicalBaseRef: canonicalBaseRef ?? null, candidateTree: target.projection.currentCandidateTree });
