+Mid A, decided by:
+
+- Navigation, Shape: `src/http/request-tracking.ts:9` `trackRequest`: the per-request logger, span and access line now live in a named module instead of the tail of the 318-line `createApp`
+- Navigation, Shape: `src/http/request-fields.ts:33` `clientAddress`: the caller-IP and X-Forwarded-For rule has its own pure function in a file named for it
+
+Inherited architect, decided by:
+
+- Locality, Shape: `src/http/request-tracking.ts:9` `trackRequest`: the exactly-once finalize and close listener are one named unit, changeable without reading `createApp`'s other state
+- Locality, Shape: `src/http/request-fields.ts:33` `clientAddress`: pure function of peer, header and list, with the reasons for reading from the right beside it
