-# TradeAC Experiment Queue — hypotheses that would prove "better trading performance"
+# TradeAC Experiment Queue — Series 2 (Q12+)

-**Purpose.** A staging queue of experiment runs, each designed to PROVE (or
-REFUTE) one hypothesis about how to achieve better trading performance on the
-TradeAC stack. Every item is pre-registered: hypothesis, change-vs-reference,
-and acceptance metric are fixed BEFORE the run (book ch.02 isolation + falsification
-discipline). Nothing here is executed yet — each entry carries its execution
-command and can be run by tracing first (`rd_trace_start` → `rd_run_workflow` /
-`rd_risk_calibrate` → `rd_trace_finish`).
+**Purpose.** The next pre-registered batch of experiments, continuing Series 1
+(Q01–Q11, exp 33–43, all executed and folded into `book/CLAIMS.md` /
+`book/EVIDENCE.md`). Each entry targets a still-unproven `HYPOTHESIS` from the
+book or an open question flagged in `CLAIMS.md`/`book/README.md`, and follows the
+Series-1 discipline: one variable changed vs the exp-26 reference, acceptance
+fixed BEFORE the run, sequential execution, trace-first, verify-then-close.

-**Source.** Mined from the `book` branch of this repo (`book/CLAIMS.md`,
-`book/EVIDENCE.md`, `book/chapters/*`, `book/references/chat-ideas.md`). Only
-clean-lake (exp 21+) facts are cited as reference numbers; pre-clean-lake claims
-are idea material that the queue is designed to test.
+**Reference / control (MUST reproduce first).** exp 26 (`21afc6af…`, mlflow exp
+25) is the campaign baseline; exp 39 (Q07, weekly rebalance) is the best
+construction. Reference config is byte-reproduced in `workflows/exp26/` on the
+`exp/26-…` branch and in this dir's `workflows/*.yaml`.

 ### Deferred (methodology / infra, P3)
- **Q12 Purged / walk-forward CV** on the exp-26 reference (book ch.02 open
-  question) — methodology improvement, not a direct alpha lever.
- **Q13 Out-of-universe validation** — non-ETF universe for the compact
-  stochastic feature set (book README open question; needs new lake symbols).
+- Purged / walk-forward CV (was queue's old Q12) — methodology, not an alpha lever.
+- PSI-based drift-aware retraining cadence — needs a drift-gate module + a retrain decision rule.
+- No-trade buffer band / notional-vs-qty sizing — siblings of Q12/Q13; queue only if weekly reproduces.
+- Macro/drift overlays (SPY>200d regime gate, momentum tilt) — needs new data pipeline.

 ## Execution protocol (per queued run)

-1. **Validate the lake first** (`validate_lake_dataset` + `rd_status`) — the
-   clean-lake lesson: silent NaN-drops and hollow coverage invalidate a run.
-2. **Trace before running** (`rd_trace_start` with the hypothesis as `rational`,
-   `evolved_from=auto` for lineage → it will fork from the closest prior
-   experiment). Use a FRESH experiment name per run, e.g. `tac-rd-q01-m2-...`.
-3. **Run** `rd_run_workflow config_path=<abs path to the queue YAML>
-   experiment_name=<fresh name>` — use `wait=false`, poll `rd_exp_get_run` until
-   `FINISHED` (4-year trains outlive the MCP call).
+1. **Validate the lake first** (`validate_lake_dataset` + `rd_status`) — clean-lake lesson: silent NaN-drops and hollow coverage invalidate a run. Q14 additionally requires backfilling the single-stock universe (bars + sp/ta features, full range, explicit `start`/`end`).
+2. **Trace before running** (`rd_trace_start` with the hypothesis as `rational`, fresh `experiment_name`, `evolved_from=auto`).
+3. **Run** `rd_run_workflow config_path=<abs path to the queue YAML> experiment_name=<fresh name>` — `wait=false`, poll `rd_exp_get_run` until `FINISHED`.
 4. **Verify against acceptance** via `rd_exp_result` (headline + backtest risk).
-5. **Finish the trace** (`rd_trace_finish` with `metrics` + `evaluation`),
-   snapshot any new custom modules (`rd_trace_snapshot`).
-6. **Report to the book** — on PROVE, update `book/CLAIMS.md`/`EVIDENCE.md`;
-   on REFUTE, record the negative (falsification is the output).
+5. **Finish the trace** (`rd_trace_finish` with `metrics` + `evaluation`), snapshot any changed contrib modules.
+6. **Report to the book** — PROVE/REFUTE → update `book/CLAIMS.md` + `book/EVIDENCE.md`.

-
-## Hypothesis (prove)
-Fractional-Kelly sizing — sizing each name by the edge magnitude of its score

-  custom `FractionalKellyDropoutStrategy` (same topk/n_drop selection, sizing ∝
-  score magnitude, capped at a fraction f of the equal-weight notional; f as a

- All signal/config unchanged (compact stochastic features, 5-seed RankIC
-  ensemble, 5d label, train/valid/test, SPY benchmark, 5bp/15bp/$5 costs).
-
-## Acceptance
- `net_IR > 0.21` AND `net_ann_return > +2.13%` (exp-26 reference), with
-  `total_cost` not higher than the reference book.
- If sizing flattens the book (over-concentration) and net degrades → REFUTED

-chat-derived, pre-clean-lake idea material). The reversal has never been tested
-as a **standalone tradable strategy net of costs**. If it clears the 20bp
-round-trip cost, it is an independent alpha source that can be blended with (or
-replace) the model book.
-Source: `book/ch01` "Timeline" + `chat-ideas.md`
-(`TODO(evidence-needed: standalone 5d-reversal strategy net of costs)`).
-
-## Change vs exp-26 reference
- This is NOT a model-construction variant — it isolates a SINGLE-FEATURE
-  signal: a model trained on `sp_trend_slope_5` (plus raw OHLCV) alone, or a
-  mechanical reversal book (rank by −`sp_trend_slope_5`, buy the most-reverted
-  topk), backtested net of costs over the exp-26 window.
- Control: exp-26 compact reference on the same window.
-
-## Acceptance
- Standalone reversal `net_ann_return > 0` (clears 20bp round-trip) — proves
-  the claim "reversal is tradable net of costs". Secondary: excess vs the
-  model book is the blend decision for a future round.
-
-## Execution prerequisites
-1. `rd_train`/workflow with `feature_fields = $open,$high,$low,$close,$vwap,$volume,sp_trend_slope_5`
-   (single feature) OR a mechanical rank backtest via `rd_backtest` on a
-   hand-built pred (pred = −rank(sp_trend_slope_5)).
-2. Trace + run + record as a standalone study (dataset-study status, not
-   necessarily a traced model experiment).

+# QUEUE-19 — Martingale / variance-ratio study close-out (no qrun)
+
+**Status:** QUEUED · **Priority:** P2 · **Effort:** ad-hoc script under `book/data/`
+
+## Hypothesis (settle)
+Assets are submartingales long-horizon / mean-reverting short-horizon
+(`VR < 1` at 5–20d). CLAIMS.md marks this HYPOTHESIS (chat-derived martingale
+study; exp 19 was opened but never closed). It is a market-structure claim, not a
+trading claim — settle it with a clean-lake script, then close exp 19 or open a
+scripted EVIDENCE entry.
+
+## Method (persist everything under `book/data/evidence/q19-vr/`)
+1. Load the 50-ETF panel 1d bars from the lake for 2015-01-01..2026-08-19.
+2. Compute the Lo–MacKinlay variance ratio at horizons 5 / 10 / 20d per symbol,
+   with heteroskedasticity-robust z-stats.
+3. Report: per-horizon VR distribution, fraction of symbols with VR < 1 and the
+   z-significance, pooled drift vs daily variance (submartingale check).
+4. Cross-check the pooled `sp_trend_slope_5` regression beta claim (β ≈ −0.53,
+   t ≈ −24) on the clean lake.
+5. Write `VR_stats.csv` + a one-page summary into the evidence dir.
+
+## Acceptance
+- VR < 1 at 5–20d for a material fraction of the panel with |z| > 2 → supports
+  the mean-reversion HYPOTHESIS; else mark REFUTED or REFERENCED.
+- The result updates CLAIMS.md's "Assets are submartingales…" row and closes the

+# QUEUE-20 — Effective independent names in the 50-ETF book (no qrun)
+
+**Status:** QUEUED · **Priority:** P2 · **Effort:** ad-hoc script under `book/data/`
+
+## Hypothesis (settle)
+The 50-ETF book has only ~4 effective independent names (CLAIMS.md HYPOTHESIS,
+chat-derived eigenvalue analysis, pre-reset). This is a concentration/diversification
+claim with direct sizing relevance; verify it on the clean lake.
+
+## Method (persist everything under `book/data/evidence/q20-effective-names/`)
+1. Load the 50-ETF panel 1d returns from the lake for the test window 2026-01-04..2026-08-10.
+2. Standardize returns; compute the correlation matrix and its eigendecomposition.
+3. Count eigenvalues above the Marchenko–Pastur bound (N=50, T≈150) and report the
+   cumulative-variance share of the top k components.
+4. Effective-rank measures: participation ratio `(Σλ)² / Σλ²` and cumulative 80%
+   variance count.
+5. Write `eigenanalysis.csv` + a one-page summary.
+
+## Acceptance
+- If effective rank ≈ 4 (top-4 explain ~80%+ variance), the concentration claim is
+  PROVEN and feeds chapter 08 sizing guidance (why topk 10→20 adds no breadth).
+- If effective rank is much larger, mark the claim REFUTED.

+# QUEUE-18 — OptimalStopControl clean re-test vs TopkDropout (exp 13/14 claim).
+# CLAIMS.md HYPOTHESIS: "TopkDropout beats stochastic-control OptimalStopControl on
+# the ensemble signal" — exp 13/14 were pre-clean-lake; never re-tested post-reset.
+# Same compact signal as the exp-26 reference; ONLY the strategy changes to
+# OptimalStopControl with exp-13 params (entry 0.85 / exit 0.7 / hold 10 / sl -0.08).
+# PREREQUISITE: tac_qlib/contrib/strategy/optimal_stop.py must be synced to the venv
+# site-packages snapshot before running (see /app/AGENTS.md).
+# Acceptance: TopkDropout net_IR >= stop-control net_IR; document cost drag of both.
+# Run: rd_run_workflow config_path=<repo>/experiments/queue/workflows/q18_optstop.yaml \
+#        experiment_name=tac-rd-q18-optstop
