32 tasks across 5 milestones (E.0 foundation → E.4 shadow-mode), with
locked design decisions from three rounds of focused research memos:
- Q1 (fill sim): medium-tier Poisson regression from 5.2M trade tape
- Q2 (reward): terminal-only, n-step credit (consumes ISV slot 517)
- Q3 (alpha trust): implicit calibrated trust via state features
- Q4 (state window): current snapshot + 2 short-horizon scalars
- Q5 (sizing): hybrid decoupled fractional Kelly × Phase E attenuation
Trainer choice: DQN primary (Rainbow + Munchausen target), PPO control
on H=600 truncated only if kill criteria fire. Exploration: ε-greedy
with kill-criteria gate at end of week 2; NoisyNet escalation (4-6 days
due to dead scaffolding in our codebase) if criteria fail; RND beyond
that.
ISV consumption: 5 existing slots (n_step=517, γ=43-46, ε=41, Kelly=280,
reward_caps=452-453); new block 539..550 reserved for Phase E (10 in
active use, 2 spare). One new controller (stacker-threshold
engagement-rate-self-correction at slot 543).
Hardcoded by design: Kelly contract cap (Category-1 safety),
kill-criteria thresholds (circuit breakers). All other knobs are
ISV-driven per pearl_controller_anchors_isv_driven.
Decisive gates at week 1 (H=600 kill criteria), week 4 (composition
backtest Sharpe at half-tick > 0), and week 5 (shadow-vs-backtest
PnL within 30%).
