+[I] 2026-07-16 — **INTEGRATION PASS (main).** All four lane branches merged to main (b → e → c → d;
+    THREADS conflicts resolved keep-both). Added the importmap D+E asked for to index.html AND
+    selftest.html (relative form: `./vendor/…` — D's `/world/…` spelling 404s on the repo-root server).
+    Same absolute-path bug fixed in dev_player.html and player.js GLB URLs (`/world/models/…` →
+    `./models/…`) — the ped never loaded under `server.py`; it does now, verified in dev_player.html.
+    Selftest on merged main: **121 pass / 0 skip / 0 fail** (E's suite lit up as promised).
+    launch.json now runs `--port 8809` (8801 was held by another session). Next work: SPRINT2.md.
