 Do not write "no release note required" for a change under this lab — a note is
 always required. State which note you added.
+
+## Boundary Conformance Requirement
+
+For every requested change, determine whether it creates, modifies, relies on,
+or crosses a system boundary.
+
+A boundary is any point where authority, state, data, effects, trust, or
+responsibility moves between components, actors, processes, repositories,
+services, or execution stages.
+
+If the change affects a boundary, boundary conformance is part of the definition
+of done. If it does not, say so explicitly (`Boundary-conformance impact: none`)
+and do not invent artificial tests.
+
+The standing rule, in three lines:
+
+```text
+Every boundary implies a control law.
+Every control law implies conformance evidence.
+Every relevant path must be shown to reach the boundary.
+```
+
+### 1. State the control law
+
+Before implementation, describe the boundary and write the invariant it must
+enforce, in this form:
+
+```text
+Boundary:          <where the transition occurs>
+Control law:       <what must always be true>
+Authorized actor:  <who may perform the transition>
+Required evidence: <what must be verified before acceptance>
+Failure behavior:  <deny, reject, retry, escalate, or fail closed>
+Release condition: <what makes the transition admissible>
+```
+
+### 2. Enforce at the correct boundary
+
+Do not only patch the observed symptom. Trace the paths that can violate the
+control law and enforce it at the earliest safe shared boundary that closes the
+failure class without unnecessary scope expansion.
+
+If the correct fix requires materially broader work, do not silently expand the
+change. Ask whether to (1) expand the current delivery, (2) split the shared
+boundary into a prerequisite delivery, or (3) apply bounded local containment
+and record the remaining risk.
+
+### 3. Add boundary-conformance tests
+
+Tests must prove the control law, not merely exercise the implementation. Add
+the applicable classes:
+
+- **Positive conformance** — the authorized actor completes the valid transition
+  when all required evidence is present.
+- **Negative conformance** — unauthorized actors, invalid states, missing/stale
+  evidence, and malformed requests are rejected.
+- **Relation conformance** — every relevant entry path reaches the intended
+  boundary; test `request → boundary → decision → effect → resulting state`, not
+  just the component in isolation.
+- **Bypass conformance** — the protected effect cannot be reached through an
+  alternate path that avoids the boundary.
+- **Failure-state conformance** — rejection leaves the protected state unchanged
+  and does not partially apply the effect.
+- **Correlation and replay** (where relevant) — request/response identities
+  match; receipts cannot cross runs; duplicate/reordered events fail correctly;
+  replay reproduces the original decision; changed policy or evidence invalidates
+  replay.
+- **Idempotency and reversal** (where relevant) — repeating an accepted
+  transition does not duplicate the effect; stale base state is rejected; a
+  recorded mutation reverses deterministically when its post-state still matches.
+
+### 4. Map tests to control laws
+
+Every boundary test must identify which control law it proves. Use a name or a
+`control-law: <slug>` comment. Avoid tests that pass without demonstrating the
+invariant.
+
+### 5. Preserve deterministic authority
+
+The model may propose implementation and tests. The deterministic boundary
+decides admissibility. Never treat an LLM assertion, completion claim, or
+generated summary as conformance evidence unless policy explicitly allows it.
+Prefer exact hashes, repository state, test results, validated schemas,
+correlated receipts, deterministic path checks, and authoritative external state.
+
+### 6. Report completion evidence
+
+Before declaring the work complete, report:
+
+```text
+Boundary:
+Control law:
+Affected paths:
+Tests added:
+Positive case:
+Negative case:
+Relation or bypass proof:
+Failure-state behavior:
+Residual risk:
+Conformance status:
+```
+
+The change is not complete while a material boundary control law remains
+untested or unsupported by evidence.
