Task Description

Review and optimize only the actor-session change set for algorithm efficiency, resource usage, caching opportunities, and unnecessary operations. Apply safe optimizations while preserving the specified legacy provenance migration behavior, GoalSessionExecutor constructor compatibility and validated constructor, mandatory execution-time validation, narrow telemetry serialization, public API/security/error behavior. Run only tests typed_ooda_actor_session_scope, typed_ooda_goal_session_workflow, and typed_ooda_security_regressions. Make no docs, dependency upgrades, unrelated refactors, or commits.

Requirements

Final Requirements

No material ambiguity remains.

1. Limit changes to actor-session performance/resource optimizations in src/typed_ooda/ledger.rs and src/typed_ooda/schema.rs; touch other files only if strictly required for correctness.
2. Preserve legacy provenance migration outcomes, transactional behavior, and fail-closed semantics.
3. Preserve both GoalSessionExecutor construction paths and all public interfaces.
4. Keep execution-time validation at every existing trust boundary; do not cache validation results.
5. Keep telemetry serialization intentionally narrow and secret-safe.
6. Preserve security boundaries, error types/messages, and observable behavior.
7. Accept only demonstrably safe reductions in allocation, cloning, serialization, hashing, database access, or repeated computation.
8. Introduce caching only if session isolation, bounded lifetime, invalidation, and tamper visibility are provably preserved; current analysis indicates no suitable caching opportunity.
9. Run only:
   • typed_ooda_actor_session_scope
   • typed_ooda_goal_session_workflow
   • typed_ooda_security_regressions
10. Make no documentation, dependency, unrelated refactoring, test-scope expansion, or commit changes.

Decision: Existing staged optimizations are candidates for retention only after confirming they satisfy these invariants and all three permitted test groups pass.

Acceptance Criteria

• All explicit requirements met
• Tests passing
