Implement deterministic healing proposal generation, approval workflow, and linked immutable version creation

[kalen-releasedgroup]

Summary

Deliver the required v1 healing workflow without bypassing deterministic evidence or human approval.

Scope

• Evaluate replay failures for deterministic locator-healing opportunities.
• Persist healing suggestions with evidence, confidence, and approval state.
• Apply approved healing by creating a new immutable scenario version linked to the originating replay run.

Requirement Links

• FR-HEAL-001, FR-HEAL-002, FR-HEAL-003, FR-HEAL-005
• Acceptance Criterion 8
• Phase 3 exit criteria

Dependencies

• Replay diagnostics baseline
• Locator candidate persistence
• Scenario version model

Exit Criteria

• Healing proposals are evidence-backed and deterministic-first.
• Persisted changes require explicit approval.
• Approved healing is fully traceable.
