+**Check data flow when adding rules.** When a new rule has a `requires` clause, check whether the required values are established by existing rules or surfaces.

+
+**Check transition graph impact.** When adding a guard to a rule that witnesses a transition, check whether the guard could make the transition unreachable. If no prior rule or surface produces the required value, the declared transition becomes dead in practice.

+**Check surface coverage for external triggers.** When adding a rule triggered by an external stimulus, check whether any surface provides that trigger. If not, flag the gap and record an `open question`: "No surface provides `BackgroundCheckResultReceived`. This rule cannot fire without an entry point for the external system."
+
+**Consider invariants for cross-entity constraints.** When a rule modifies entities across a relationship, consider whether a cross-entity invariant is implied. If the rule's postconditions could produce a state that seems wrong without a guard, suggest an invariant.
+
+**Assess the spec before editing.** Read [assessing specs](../../references/assessing-specs.md) to understand the spec's maturity. Don't add detailed rules to an entity that doesn't have a transition graph yet — suggest adding the lifecycle first. Don't add surfaces without actors.

 ## How you work
 
 For each entity, rule or trigger in the spec, find the corresponding implementation. For each significant code path, check whether the spec accounts for it. Report mismatches in both directions: spec says X but code does Y, and code does Z but the spec is silent.
 
+### Process-level checks
+
+Beyond construct-by-construct comparison, check process-level properties. Read [assessing specs](../../references/assessing-specs.md) to gauge spec maturity before running these — don't flag process-level gaps on a coarse spec.
+
+- **Transition reachability in code.** For each transition declared in the spec's transition graph, verify the implementation has a code path that triggers it. If a transition is declared but no code path produces it, report it.
+- **Surface-trigger coverage.** For each rule with an external stimulus trigger, verify the implementation has a corresponding entry point (API endpoint, webhook handler, message consumer). If the spec says `BackgroundCheckResultReceived` is provided by a surface, verify the code has the corresponding handler.
+- **Undeclared transitions in code.** Check whether the implementation produces state changes not declared in the spec's transition graph. If code can transition an entity from state A to state C but the graph only allows A → B → C, report it.
+- **Invariant enforcement.** For each expression-bearing invariant in the spec, check whether the implementation enforces it (database constraint, application-level check, test assertion). If no enforcement exists, report the gap.
+- **Bottom-up process reconstruction.** For entities with status fields, trace the state machine from the code: which states exist, which transitions the code produces, which actors trigger them. Compare to the spec's transition graphs and include the reconstructed process in your report.
