docs: log respawn rollout across stack nodes

   lake on :9001) launched but had no respawn, so a boot-time race left it permanently
   dead. Added respawn=True to its launch Node. W8 mode indicator built + validated live
   (render+data). W1/W8 confirmed GREEN/AUV once bridge up.
+- 2026-07-08 — FLAGGED (open): recording_manager.py still implements superseded DIR-9
+  (continuous-from-boot recording), NOT the governing DIR-9a (ARM-bounded black-box:
+  AUV ARM-start/DISARM-stop, ROV operator manual + arm reminder). Design decision
+  exists only in handover + CLAUDE.md; code never updated. foxglove_mcap.launch.py
+  comments also still say DIR-9. Also: argonaut-stack.sh passes record:=${RECORD} but
+  rov_full.launch.py declares no such arg, so RECORD=false is silently ignored and
+  bags record regardless. Both deferred to a dedicated DIR-9a recorder-rework session
+  — do NOT wire RECORD into the current DIR-9 model.
+- 2026-07-08 — Added respawn=True/respawn_delay=5.0 to failsafe_monitor,
+  motion_controller, ekf_filter_node, depth_node, mission_executor. Deliberately NOT
+  applied to: mavros_node (respawn could mask/worsen the chronic FCU-link instability
+  — belongs in that investigation), recording_manager (pending DIR-9a rework),
+  camera_node/feature_detector (perception not operational yet), foxglove_bridge
+  (viz-only). NOTE: failsafe_monitor respawn has a coverage gap during the 5s respawn
+  delay — no failsafe assessment in that window; flagged for future design
+  consideration.
