PHASE 7 FREEZE CHECKLIST — FINAL GATE FOR IMMUTABILITY¶

Project: AeroDB Phase: Phase 7 — Control Plane, Admin UI, and Operator Tooling Status: AUTHORITATIVE · FREEZE GATE

1. Purpose of This Document¶

This document is the final, mandatory checklist required to freeze Phase 7.

It exists to:

• Eliminate ambiguity
• Prevent assumption-based freeze decisions
• Force explicit verification of all Phase 7 guarantees

Phase 7 MUST NOT be frozen unless every item in this checklist is satisfied and explicitly confirmed.

This checklist is binary.

2. Freeze Rule¶

If any checklist item cannot be answered “YES” with evidence, Phase 7 MUST NOT be frozen.

No partial freeze is allowed. No conditional freeze is allowed.

3. Documentation Verification¶

Confirm that the following documents:

• Exist
• Are complete
• Are internally consistent
• Are mutually non-contradictory

Required Documents¶

• CONTROL_PLANE_VISION.md
• CONTROL_PLANE_SCOPE.md
• CONTROL_PLANE_INVARIANTS.md
• CONTROL_PLANE_AUTHORITY_MODEL.md
• CONTROL_PLANE_FAILURE_MODEL.md
• CONTROL_PLANE_STATE_MODEL.md
• CONTROL_PLANE_CONTROL_PLANE_ARCHITECTURE.md
• CONTROL_PLANE_COMMAND_MODEL.md
• CONTROL_PLANE_CONFIRMATION_MODEL.md
• CONTROL_PLANE_OBSERVABILITY_MODEL.md
• CONTROL_PLANE_ERROR_MODEL.md
• CONTROL_PLANE_AUDITABILITY.md
• CONTROL_PLANE_TESTING_STRATEGY.md
• CONTROL_PLANE_READINESS.md
• CONTROL_PLANE_FREEZE_CHECKLIST.md

If any document is missing or contradictory → FAIL.

4. Invariant Enforcement Verification¶

Confirm that every Phase 7 invariant:

• Is enforced in code
• Is enforced by tests
• Cannot be bypassed via UI
• Cannot be bypassed via CLI

Any invariant that exists only on paper → FAIL.

5. Command Surface Verification¶

Confirm that:

• All operator commands are defined in CONTROL_PLANE_COMMAND_MODEL.md
• No undocumented or experimental commands exist
• Each command maps to exactly one kernel action

Any undocumented command → FAIL.

6. Confirmation Safety Verification¶

Confirm that:

• All mutating commands require explicit confirmation
• Override commands require enhanced confirmation
• No command executes without confirmation
• Confirmations are non-reusable and non-durable

Any execution without confirmation → FAIL.

7. Failure Handling Verification¶

Confirm that:

• Control-plane crashes do not mutate kernel state
• Network failures do not cause partial execution
• Ambiguous outcomes are treated as not executed
• No automatic retries mutate state

Any ambiguous execution outcome → FAIL.

8. Auditability Verification¶

Confirm that:

• Every command attempt produces an audit record
• Every confirmation produces an audit record
• Every failure produces an audit record
• Control-plane crashes do not erase audit data
• Audit records support full reconstruction

Missing audit trail → FAIL.

9. Observability Isolation Verification¶

Confirm that:

• Observability is passive
• Observability cannot trigger actions
• Observability failures do not affect behavior

Any observability-driven action → FAIL.

10. Non-Interference Verification¶

Confirm that:

• Kernel behavior is identical with Phase 7 disabled
• Phase 7 does not alter kernel timing or ordering
• Phase 7 does not alter durability semantics

Any interference → FAIL.

11. Testing Verification¶

Confirm that:

• All tests defined in CONTROL_PLANE_TESTING_STRATEGY.md pass
• All invariants have negative tests
• No flaky or nondeterministic tests exist

Test gaps → FAIL.

12. Explicit Non-Existence Verification¶

Confirm that Phase 7 contains none of the following:

• Automation
• Heuristics
• Background control loops
• Recommendation engines
• Silent retries

Presence of any above → FAIL.

13. Responsibility Confirmation¶

Confirm that:

• Operator responsibility is explicit
• Overrides transfer responsibility clearly
• No action is executed without accountability

Unattributable actions → FAIL.

14. Final Freeze Declaration¶

Phase 7 may be frozen only if:

• All checklist items above are checked
• All failures have been resolved
• No open TODOs or deferred correctness work exists

When all conditions are met, record the following:

• Freeze Date: ______________________
• Freeze Authority: __________________
• Evidence Location: _________________

15. Final Statement¶

Phase 7 freeze is a point of no return.

After freeze:

• Phase 7 behavior is immutable
• Any change requires reopening the phase

If there is doubt, do not freeze.

This checklist is the final authority.
