-- **NARC/STREAK per-type seeker maneuverability (Oracle: the "angry swarm of bees" at high

+- **NARC/STREAK per-type maneuverability -- MECHANISM FOUND (#113 audit, 2026-08-14) [T1]:
+  the authored turn rate is model field +0x40** (values 60/360 deg/s), scaled by
+  _DAT_004be8b8 = pi/180 into the thruster (@004bf5b4 stack-record build -> @004be7c4
+  thruster[0x3a], rad/s).  The +0x4c candidate hypothesis was WRONG (superseded; +0x4c ->
+  thruster[0x3c], role unread).  The binary flies the authored rates; the port's push
+  simulator uses uniform PORT-TUNED steering gains (4.0/8.0) [T3] and ignores +0x40.
+  SUNDAY ITEM: consume model+0x40 as the per-round turn gain (the table already caches the
+  record; add the field), bench LRM-vs-Streak turn-radius A/B, expect the 'angry bees'.
+  Same audit, envelope verdict: ttl = lifetime + 10.0 (_DAT_004bf5ac) and kill-plane -1.0
+  (_DAT_004bf5b0) are BYTE-FAITHFUL in the port -- #113 closed-faithful, no envelope change.
+  [T3 minor ledger]: the binary also silently retires rounds the constraint resolver
+  displaces >0.32u (embedded-in-terrain reaper, no boom) beside the detonating
+  world-collision path; and a thruster-state branch zero-stabilizes lateral terms during
+  burn (our seeker-loft shape approximates).
