-# TradeAC Experiment Queue — Series 2 (Q12+)
-
-**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.
-
-**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`.
-
-| Config element | exp-26 reference value |
-|---|---|
-| Universe | 50-ETF panel (`UNIVERSE` below) |
-| Features | compact stochastic 25-field set (no ou/hmm/moments/garch) |

-| Q12 | **22d label + weekly recompute** — the untested combo: Q05's label edge (IC 0.097, RankIC 0.117) with Q07's cost relief | label → 22d AND strategy → weekly (two coupled, explicitly pre-registered) | net_IR > 0.5, net_ann > +5%, cost drag ≤ 2pp | `workflows/q12_label22d_weekly.yaml` | ✅ |

-| Q14 | **Out-of-universe validation** — compact stochastic set generalizes off the 50-ETF panel to a single-stock universe | universe → 30 liquid single names | RankIC > 0.03, ICIR > 0.15, net IR > 0 on stocks | `workflows/q14_out_of_universe.yaml` | ⚠️ needs stock-lake backfill (see design) |
-| Q15 | **5-seed vs single-model clean A/B** — seed-count claim (exp 12 idea, re-validated exp 22–24, never a clean A/B) | seeds → 1 (`2026`) | single-model RankIC/IR < 5-seed ref; net_IR ≥ 0.21 acceptable if ≥ single | `workflows/q15_single_seed.yaml` | ✅ |
-| Q16 | **HMM family added as features** — settles "dropping model-specific (ou,hmm) improves signal" (exp 25 tested OU; hmm-as-feature untested) | features += `sp_hmm_p_regime1,sp_hmm_state` | no improvement: RankIC ≤ 0.0663, net_IR ≤ 0.21 | `workflows/q16_hmm_features.yaml` | ✅ |
-| Q17 | **Realized-moments family added** — settles "moment/volatility families regress" (exp 11 idea, never clean A/B) | features += `sp_rskew_5,sp_rskew_22,sp_rkurt_5,sp_rkurt_22,sp_dsv_5,sp_dsv_22` | no improvement: RankIC ≤ 0.0663, net_IR ≤ 0.21 | `workflows/q17_moments_features.yaml` | ✅ |
-| Q18 | **OptimalStopControl clean re-test** — exp 13/14 claim (TopkDropout > stop-control) never re-tested post-reset | strategy → `OptimalStopControl` (exp-13 params) | TopkDropout net_IR ≥ stop-control net_IR; document cost drag | `workflows/q18_optstop.yaml` | ✅ (module verified in venv) |
-| Q19 | **Martingale / variance-ratio study close-out** — exp 19 never closed; VR<1 at 5–20d on clean lake | ad-hoc script (no qrun) | VR stats + drift decomposition on 50-ETF panel | `designs/q19_martingale_vr.md` | ✅ script |
-| Q20 | **Effective independent names (≈4)** — eigenvalue analysis on clean-lake covariance | ad-hoc script | eigenvalue spectrum + effective-rank count | `designs/q20_effective_names.md` | ✅ script |
-
-### Deferred (methodology / infra, P3)
- 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`) — 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 changed contrib modules.
-6. **Report to the book** — PROVE/REFUTE → update `book/CLAIMS.md` + `book/EVIDENCE.md`.
-
-Sequential execution only (concurrent runs hang — chat-ideas.md ops lesson). Any
-custom strategy/module changed here must be copied into the venv site-packages
-snapshot before `rd_run_workflow` can import it (see `/app/AGENTS.md`). As of
-2026-08-20 `WeeklyRebalanceDropoutStrategy` and `OptimalStopControl` are verified
-in sync with the venv snapshot; the lake already persists the `sp_hmm_*` and
-`sp_moments` families on the 50-ETF panel.
-
-## Provenance
-
-Mined 2026-08-20 from `book/CLAIMS.md`, `book/EVIDENCE.md`, `book/README.md`,
-`book/references/chat-ideas.md`, and Series-1 `queue/` (Q01–Q11, executed exp
-33–43). Reference numbers are post-clean-lake (exp 21+).

-# 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
-  exp-19 open thread.

-# 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.
