Glossary
Internal records use short codes so plans and registrations keep stable identities. A code is only a label. It is not a quality mark, a profit claim, or proof that the work is active.
Plan codes
| Code | Plain name | Meaning |
|---|---|---|
| P1 | Appliance mode | The closed plan that once framed the engine as a maintain-only service. |
| P2 | League collapse | Retires old paper books that no longer answer a live research question. |
| P3 | Point-in-time data | Builds survivor-aware historical membership and data inputs, using free sources first. |
| P4 | Broker decision | Records the long-term broker choice while granting no connection or trading authority. |
| P5 | Agent paper decisions | Lets one constrained agent create orders only in an isolated simulator book. |
| P6 | Alpha experiment | Ran one frozen deterministic SPY/BIL experiment and preserved its negative result. |
| P7 | Autonomous paper trial | Compares rule-only, AI-only, and hybrid allocation books on the same paper capital. |
| P8 | Daily opportunity agent | Reviews nightly market standouts and can use one locked simulator-only trade tool. |
| P9 | Multi-cadence agent tools | Adds hourly and four-hour shadow observers around the nightly agent path. |
| P10 | Contamination-aware 2022 replay | Replays a few old decisions as a diagnostic, not as evidence of predictive skill. |
| P11 | Forward agent evaluation | Joins frozen agent decisions to later outcomes in an append-only evaluation record. |
| P12 | Agent research product | Brings agent data, execution, evaluation, and status views into one programme. |
| P13 | Market-data source hardening | Adds exact-response, research-only adapters and explicit source-admission rules. |
| P14 | TradingView historical archive | Collects a resumable, survivor-biased daily-bar archive for research only. |
| P15 | Profitability evidence loop | Scores every candidate, runs paired paper books, and tests the model against a rule. |
| P16 | Challenger lab, text edge, and evaluation science | Builds shadow challengers, text labs, stronger statistics, portfolios, and execution measurement. |
| P17 | Personal-host IBKR paper execution | A proposed future broker paper plan on personal hardware; explicitly not work for now. |
| P18 | Shared backtest core | Supplies one public point-in-time evaluator for event and portfolio studies. |
| P19 | Offline market-data auditor | Measures signal-input coverage against an independent reference population, with a fictional omission demo. |
| P20 | Engine and paper dashboard review | Reviewed and fixed the engine and dashboard against real host evidence. |
| P21 | Operational issue closure and separate accounts | Closed operational issues and proved isolated paper accounts for separately held strategies. |
| P22 | Engine v2 accounts and money | Made the engine the single executor and ledger for paper accounts: commissions, auction and intraday fills, shorts, margin and halts. Live since 2026-10-18. |
| P23 | Hourly operations digest | Summarizes every scheduled run, stage and log signal each hour so an agent can investigate failures on demand. |
| P24 | Senior-quant review | The active 2026-10-21 review: pipeline and data-integrity fixes, statistics audit, output-identical speed work, and new private research studies. |
The plan index is the single source of truth for status. “Done” means the planned work finished; it does not mean the strategy was profitable.
Workstream codes
Workstream codes are local to their plan. W8 alone is ambiguous: the profitability evidence loop’s W8 means activation, while the challenger lab’s W8 means Stage 2 design.
| Plan | Code | Plain name |
|---|---|---|
| P15 | W0 | Baseline and safety |
| P15 | W1 | Observer evidence |
| P15 | W2 | Scoring and deterministic baseline |
| P15 | W3 | Comparator paper books |
| P15 | W4 | Cancel-only pre-open reassessment |
| P15 | W5 | Shadow event triggers |
| P15 | W6 | Gates and reporting |
| P15 | W7 | Cleanup and documentation |
| P15 | W8 | Activation |
| P16 | W0 | P15 remediation and activation |
| P16 | W1 | Evaluation science |
| P16 | W2 | Challenger lab |
| P16 | W3 | Filing reader |
| P16 | W4 | Historical text and replay labs |
| P16 | W5 | Portfolio construction |
| P16 | W6 | Execution realism |
| P16 | W7 | Operator digest |
| P16 | W8 | Stage 2 design |
| P16 | W9 | Cleanup, registration, rehearsal, and activation |
| P16 | W10 | Final refine pass |
| P16 | W11 | Synthetic proving ground |
Research terms
| Term | Plain meaning |
|---|---|
| Registration | The frozen statement of a policy, data rules, costs, test, and kill condition before evidence is seen. |
| Revision | A newly issued registration for an allowed change; old evidence and versions are not silently rewritten. |
| Holdout | A sealed slice of data opened once, after development choices finish, to test the idea on unseen data. |
| Census | The count of every tried policy or variant, used to correct for the luck of trying many ideas. |
| DSR | Deflated Sharpe ratio: a Sharpe check adjusted for the number and similarity of trials and for non-normal returns. |
| Walk-forward | Repeated development and evaluation across advancing time windows, with evaluation always later than selection. |
| Control | A frozen rule or benchmark measured on the same dates and inputs as the policy being judged. |
| Cohort | Decisions produced by one frozen policy version under one registered set of rules. |
Paper and operations terms
| Term | Plain meaning |
|---|---|
| Paper book | A simulated portfolio with orders, fills, cash, positions, and costs, but no broker or real money. |
| League | The nightly table that ranks active paper books by return and shows each result against SPY. |
| Snapshot | An immutable capture of state, such as a consistent read-only database copy or dated metrics record. |
| Evidence validator | Deterministic code that checks identities, timestamps, source bytes, labels, and report inputs before accepting evidence. |
| Next-open fill | An order decided from one session that may fill only at a later session’s open. |
| Shadow decision | A retained model or rule decision with no authority to place even a simulator order. |
| Point-in-time | Data exposed only when it would truly have been available to the decision being replayed. |
| Kill condition | A rule frozen before testing that stops an idea when its evidence is too weak or its risk is too high. |
| Engine v2 | The account and money foundation live since 18 October 2026: one ledger for every paper book and account, with commissions, auction and intraday fills, shorts, margin, and halts. |
| D0 | The recorded break date (19 October 2026) from which every book pays commissions and its evaluation clock restarted. |
| Provisional bar | A price bar stored on the night of its own session that the source may still correct; it is asked for again and never prices a fill while its open is impossible. |
| Invariant monitor | A shadow check that compares each published snapshot against store-wide rules, such as one price basis per stock, and reports regressions without changing data. |
