Methodology
Continual reinforcement learning with delayed market feedback.
Peaceful Beaver is the public name of the deployed policy. At each decision time it maps the information then available to an action. Market outcomes are labeled later and used in controlled batch updates. Published decisions are not revised.
State and observations
Issuer state is only partially observed, and market dynamics change over time. We therefore use POMDP notation. The observation \(o_t\) contains news available by the decision time, issuer evidence, price response, liquidity and market regime. The memory state \(\mathcal{M}_t\) contains only records available at or before \(t\).
Policy and risk constraint
The Scout Policy, \(\pi_{\mathrm{S}}(a\mid b_t)\), proposes candidate actions. The Risk Critic estimates downside cost and constraint violations for those actions. It may reject a proposal but does not add candidates. The Portfolio Arbiter applies the policy and risk thresholds and records the final action.
Reward definition
Reward is not fully observed when an action is published. It is labeled over fixed later horizons. The reward includes benchmark-relative return, adverse excursion, thesis persistence, false-positive cost and action cost. Coefficients are fixed for an evaluation cycle so that challenger policies are compared on the same objective.
Trajectory and credit assignment
Each decision has a stable identifier linking its observation state, action, source timestamps and later outcome labels. Opportunity selection, risk review and final arbitration are stored separately. This permits component-level error analysis without changing the original record.
Replay memory
The replay set stores point-in-time trajectories. Hot, warm and cold are retention tiers: active cases, comparable prior regimes and consolidated long-horizon cases. Sampling weights may use recency, state similarity, policy disagreement and temporal-difference error. Retrieval is bounded and respects the decision timestamp.
Batch policy update and evaluation
Production data are generated by behavior policy \(\mu\). A challenger \(\pi_{\theta'}\) is fitted on discovery windows, tuned on separate calibration windows and evaluated once on a frozen holdout. Promotion requires higher estimated policy value and no deterioration in downside, evidence or stability constraints. The production policy does not update after an individual request or outcome.
Computation policy
Research depth is included in the action. Routine states may stop after the standard pass. Weak evidence, unusual states or disagreement between policy and critic can request additional research. Compute cost is included in the objective.
Relation to True Intrinsics
The True Intrinsics research program starts from the Big World Hypothesis: the environment is larger and less stationary than a fixed model. Here that assumption is implemented through point-in-time state estimation, replay across market regimes, delayed reward labels and repeated policy evaluation. Market outcomes provide the external feedback signal.
Publication record
A dated page is generated only after the decision and memory snapshot pass publication checks. It contains the action, evidence state and decision time recorded for that date. Later outcomes may affect a future batch update, but they do not alter the published page. Public evidence may identify news publishers, company releases and regulatory filings; internal services and licensed-data implementation details are omitted.
