Drafts `pearl_diagnostic_decomposition_before_reward_intervention` per
the plan's Task 0.5 deliverable. Captures the discipline pattern
applied in Tasks 0.1–0.2:
Before changing reward weights or Bellman target arithmetic to fight
a Q-attractor, instrument a per-action decomposition of the existing
reward components AND a trajectory observable on the Q-target
distribution. The instrumentation is observability-only and lands
atomically. One epoch of dispatch surfaces whether the suspected
pathology is real BEFORE any production-path code changes.
Pearl is DRAFT — pending the Task 0.3 (reviewer L40S 1-epoch
dispatch) + Task 0.4 (KILL CRITERION evaluation) outcomes. Promotion
to user memory + cross-reference to MEMORY.md is gated on both legs
returning PROCEED.
