+# Internal Adversarial Review
+
+- Gate: IAR
+- Repository: transpara-ai/agent
+- Draft PR: #34
+- Exact reviewed head: `f3eabbdc502963244743331b0d0b2f409dee127c`
+- Author family: Codex/OpenAI
+- Result: pass
+- BLOCKER_COUNT: 0
+- Live-head equality: local, pushed branch and draft PR head matched at review time
+- Base: authenticated PR base on `main`
+- Design: `TLC51-CIVILIZATION-GATE-GOVERNANCE-DESIGN@0.4.0`, Git blob `14cc032d3252855d264d28b7fbd7cb57048fc82b`
+- Factory Order: Git blob `e9f75ca5a273c22e281d9a6a05a7844fe0fca878`
+
+## Scope and changed files
+
+- `.tlc/tlc51-migration.blocked.json`
+
+The exact diff was checked for design/Factory Order mismatch, path-boundary drift, authority leaks, stale generated artifacts, weak validation, runtime/protected-action drift, reviewer-family assumptions and closure overclaims. The PR remained draft. The later commit containing this report is mechanical review evidence only; the implementation head above is the exact IAR subject.
+
+## Validation
+
+- `make verify`: pass. Repository suite passed; the only change is the fail-closed migration stop.
+
+## Findings and dispositions
+
+- No findings.
+
+## Residual risks retained
+
+- TLC51-RR-ORG-CONTROLS
+- TLC51-RR-MUTABLE-PROVIDER-RECORDS
+- TLC51-RR-APP-ENVIRONMENT-CAPABILITY
+- TLC51-RR-DUAL-PROTOCOL-RUNTIME
+- TLC51-RR-FACTORY-BINARY-SOURCE
+- TLC51-RR-NONATOMIC-MULTIREPO-CUTOVER
+- TLC51-RR-NONATOMIC-SETTINGS-API
+- TLC51-RR-UNTRUSTED-GITHUB-CONTROLLER
+- TLC51-RR-TLC-REPOSITORY-CONTROLS
+
+These are implementation-verification obligations and fail-closed future stops. They are not satisfied or closed states.
+
+## Non-authorizations
+
+- PR readiness
+- merge
+- release or tag
+- installation or distribution
+- pilot or adoption
+- workflow activation or settings enforcement
+- runtime or deployment
+- canary or rollout
+- rollback or retirement
+- deletion, archival, or issue closure
+- any other protected effect
+
+IAR is same-family evidence. It does not satisfy CFAR, create PR readiness, or authorize any protected effect.
