+- [ ] **N/A** — this change does not touch schema, APIs, dependencies,
+      cryptography, data placement, or smart-contract counts.
+      _(If ticked, skip the remaining boxes in this section.)_
+- [ ] **Secret hygiene** — I confirmed no API keys, tokens, `.env` contents,
+      private keys, or credentials appear anywhere in the diff.
+- [ ] **Prohibited dependencies** — this PR introduces no Flutter,
+      Couchbase, or CouchDB-as-datastore dependency, and contains no
+      reference to a fixed 10-billion MXT supply cap.
+- [ ] **Schema.org compliance** — new database tables, columns, or API fields
+      map to Schema.org types, or the PR description justifies any deviation.
+- [ ] **Locked counts respected** — no change to the platform's locked counts
+      (17 mini-apps · 7 Enterprise products · 7 data layers · 7 covenants ·
+      40 interest categories · 12 manifesto sections · 3 sources of truth)
+      without Founder approval documented in the PR description.
+- [ ] **Frontier defaults** — for user-facing or infrastructure work:
+      offline / local-first behaviour has been considered; any new
+      cryptographic primitive has a documented post-quantum migration path;
+      edge-native placement has been addressed.
+- [ ] **New GitHub Actions** are pinned to a 40-character commit SHA
+      (not a floating tag) per NA-03 §7.1.1.
