jgrusewski 87b52ea946 plan(dqn-v2): Plan 3 second revision — reconcile with landed reality
Tasks 1, 2, 3, 5 landed on main between a59e7599c and a0abc3da3. The
remaining Task 4/6/7/8/9 bodies in the plan had accumulated drift:

- Task 4: allocated slot 49 (already PLAN_THRESHOLD_INDEX); EMA'd
  plan_params[0] (kernel compares against readiness).
- Task 6: allocated 59/60/61 (now collides with Plan 2 Q-quantile
  [50..58) and Task 1 reward EMAs [63..69)); required 6 new PS memo
  fields and included tuned 0.5e-4f penalty.
- Task 7: allocated 58/63/64 (63/64 collide with REWARD_TRAIL_EMA /
  REWARD_MICRO_EMA from Task 1); amplification formula had tuned
  2.0× trigger, 0.02 decay, 1.0/2.0 endpoints.
- Task 8: referenced trainer helpers that don't exist
  (sample_state_feature_pair, step_scripted, replay_insert_with_
  priority_scale); tuned priority_scale=0.5.
- Task 9: used pre-pivot CPU-compute AdaptiveMonitor pattern with
  tuned 0.9/0.1 EMA rates.

This revision:
- Adds per-task "Reality reconciliation" sub-header flagging the
  stale premise being fixed.
- Marks landed tasks with  LANDED <SHA> and records actual outcomes
  (vs. the planned outcomes the original text described).
- Rewrites Task 4/6/7/8/9 bodies to use tail-append slot allocation
  (indices recomputed from ISV_TOTAL_DIM at impl time), GPU kernel
  producer + read-only AdaptiveMonitor consumer pattern, and
  ISV-derived adaptive coefficients in place of tuned constants.
- Splits Task 6 into 6a/6b/6c with independent PS-slot additions
  (MIN_PNL / REGIME_SHIFT_BAR / PRE_ENTRY_CONVICTION_EMAs).
- Enumerates concrete trainer-helper prereqs for Task 8.
- Updates Task 10 metric bands to match actual landed ISV slot names.
- Updates exit criteria summary to check off what landed.

No code changes.
