+### N.5 Capability map + backlog (end-of-session checklist — easy to forget)
+If the task **changed what the platform can do** (new/removed capability, or a capability moved
+status), update in the SAME session:
+- **`architecture/00-capability-map.md`** — add/adjust the affected *scenario* row with the correct
+  **status** (PROVEN-LIVE requires an `audits/`|`tests/` citation; else IMPLEMENTED/PARTIAL) and an
+  evidence citation. A leg not exercised live → PARTIAL/IMPLEMENTED with a note saying which leg and
+  a `→ R-n` pointer, never PROVEN-LIVE.
+- **`backlog/ROADMAP.md`** — add any new open work / deferred legs as an item (next free `R-n`),
+  collapse a now-shipped item to its one-liner + version, and honor the **coupling rule** (every
+  roadmap item names the map row it flips; every map gap row points back by ID). Parked sub-features
+  (e.g. an alternative transport, an agent-plane leg) go as a note under the owning arc's item.

+### N.6 Website version bump (if controller/hub version is shown on the site).
