+The [GitHub release](https://github.com/mikecarper/MeshCore/releases/tag/v1.17.1.6-halo-keymind-cascade-dev-306feebe)
+contains **553 qualified firmware profiles across five release pages**. The
+initial matrix completed all 565 attempts: 537 passed, 16 failed, and 12
+standard ESP32 profiles exceeded the 1.25 MiB portable slot. All 16 failures
+have passing repair builds; all 12 portable exclusions have qualified expanded
+Full alternatives. Smaller profiles that fit remain available.

+The initial firmware uses `306feebe`, the 14 nRF52 repairs use `283acd27`, and
+the two Tracker MQTT repairs use `1274956f`. Each firmware filename and target
+manifest records its source. Existing firmware assets and release tags were
+preserved when the repairs were added.
