   bytes, and the T1's from 72,868 to 81,844 bytes. Required startup allocations
   fall from 88,410 to 79,010 bytes. These are linked capacity checks, not soak
   measurements. Full Companion capacities are unchanged.
+- Tracker v1.1 and v2 Full MQTT repeaters retain their board-defined 50
+  neighbors so the color display, MQTT/TLS and OTA fit in internal RAM.
+  Their radio, display, sensor and update features remain enabled; ordinary
+  Tracker repeater and Companion capacities are unchanged. Tracker v2's
+  available startup heap rises from 184,640 to 222,992 bytes against the
+  unchanged 190,386-byte requirement. Both corrected Tracker profiles pass.
 - Size-failure detection keeps its temporary output log outside PlatformIO's
   build tree, so SCons cleanup cannot erase the evidence needed by the measured
   size fallback. CI exercises cleanup, ordinary compiler failures and log errors.
