research: prepare effective risk floor ab

TradeChart shows a fixed 21-bar window. Once a trade is older than that,
its entry bar precedes the window and entryIdx goes negative, so the price
and trail paths index past the start of series/stopPath and emit NaN
coordinates -- the browser then drops both paths entirely, leaving only the
horizontal level lines. Clamp the index to the left edge and drop the entry
marker when the entry bar is outside the window; the full-width entry line
already carries it.

 # Signal Dashboard
 
-Investing-signal platform for NASDAQ stocks. Surfaces the best trading opportunities through weighted multi-dimensional scoring — technical indicators, support/resistance quality, sentiment, fundamentals, and momentum — with asymmetric risk:reward scanning.
+Investing-signal platform for US equities. It runs one strategy, and it is a boring one:
 
-**Philosophy:** Don't predict price. Find the path of least resistance, key S/R zones, and asymmetric R:R setups.
+> **A long-only cross-sectional momentum book.** Buy the top quintile by beta-adjusted 12-1 month momentum, tilt toward higher volatility, hold at most 10 names, cut at 1.5× ATR, then trail at 3× ATR for up to 30 trading days. After an initial-stop exit, re-enter only after the gate has failed and subsequently qualified again.
+
+**Philosophy:** don't predict price — rank it. The edge is *relative* strength across the universe, and the discipline is in the exit: cut losers fast, let winners run until the trail catches them.
+
+**What is NOT the edge — read this before trusting a number on screen.** The composite score, the 5 dimensions, sentiment, fundamentals, and Structural S/R are **display context**, not validated predictors. The Gate Target Ladder is screening machinery that preserves the production setup population; it is not a claim about true market structure. In particular:
+
+- **The headline "target" is not an exit.** It comes from the internal **Gate Target Ladder** and exists only to compute the R:R and reach-probability used by the activation gate. Human-facing chart S/R is a separate model. The live exit reads neither. Across 472 trades in the current daily gate-reset replay, the exit reasons were **229 initial stop, 147 trailing stop, 96 max hold — and 0 targets.** Honoring the target as a take-profit was tested and *halves CAGR* ([research](docs/research/sr-levels-and-exits.md)).
+- **The composite score does not select trades.** Residual momentum does.
+
+Full experiment log — everything tested, kept, and rejected: **[docs/research/](docs/research/README.md)**.

+
+**How to read the exit box.** The initial stop is tight (1.5× ATR) and the trail is wide (3× ATR), so the trail sits *below* the initial stop at entry and only takes over once price has advanced roughly 1R. Cut fast when wrong; give room once right. That asymmetry is what produces the right-tailed return profile the strategy depends on — most trades lose a little (win rate 36.2%), a few win big (best trade +12.0R), and *that is why there is no take-profit*.
+
+**What happens after an initial stop.** The stop always closes the trade and realizes its costs. The ticker is then locked until a successful daily full-universe scan first observes it outside the production gate and a later scan observes a fresh qualification. A continuously qualified ticker therefore cannot generate an immediate duplicate entry. Other exit reasons do not start this reset. See the [daily post-stop re-entry study](docs/research/post-stop-reentry.md).
+
+**Live timing matters.** The **only** full-universe R:R scan runs near the US close (~15:30 ET), then Telegram alerts fire immediately so manual fills can still hit MOC. Outcome eval runs later (~16:45 ET) after a fresh OHLCV fetch of the final bar. Morning jobs refresh data/sentiment/regime without scanning. Stops closed by earlier same-day intraday outcome evals can get a **same-day** fail observation at the near-close scan — closer to the promoted research `gate_reset` arm than the old morning-scan `strict_gate_reset` analogue. Stops after the bell still need a later day. Same-day fail+qualify cannot unlock: `trade_policy` requires the failure to fall on an earlier America/New_York trading date.
 
 ## How It Works
 
-Scheduled pipelines turn raw prices into a ranked, gated list of tradeable setups. Everything downstream of OHLCV is recomputed from stored data, so each refresh is cheap and idempotent. Job timing is cron-based and configurable in **Admin → Jobs** (default timezone Europe/Berlin).
+Scheduled pipelines turn raw prices into a ranked, gated list of tradeable setups. Everything downstream of OHLCV is recomputed from stored data, so each refresh is cheap and idempotent. Job timing is cron-based and configurable in **Admin → Jobs** (default timezone **America/New_York** so the near-close scan tracks the cash close through DST).
 
-### Daily Load — the full refresh
+### Price-level architecture: two different jobs
 
-Once a day (default 07:00). Steps run **in dependency order**, each consuming the previous step's fresh output:
+The platform deliberately has two price-level components. Calling both of them
+"S/R" hid an important distinction, so the internal screening component is now
+named the **Gate Target Ladder (GTL)**.
 
-1. **OHLCV** — fetch the latest daily bars for every tracked ticker (Alpaca); new tickers backfill ~5 years.
-2. **Sentiment** — fetch sentiment for the names that matter and are stale (> 5 days): top-pick feeders (residual-momentum leaders with a tradeable long setup), the watchlist, and open paper trades, plus a top-N-by-composite discovery net. Runs *before* the scan so the scan sees fresh sentiment.
-3. **R:R Scan** — recompute S/R zones, the 5-dimension scores and long/short setups (ATR stops, S/R targets) for every ticker, and attach each ticker's residual 12‑1 momentum activation percentile plus the promoted 80/20 production rank.
-4. **Outcome Eval** — resolve setups that hit target/stop or expired (default 30 trading days) and auto-close paper trades per the exit policy (default: 3x ATR trail with a 30-trading-day max hold).
-5. **Market Regime** — recompute the regime index (breadth/trend).
-6. **Regime Monitor** — observational early-warning snapshot (VIX, credit spreads via FRED); feeds nothing else.

+```
+
+The Gate Target Ladder works step by step:
+
+1. Build 20 evenly spaced centers over the ticker's observed high/low range and add unfiltered five-bar swing pivots. Volume is not used.
+2. Count how often historical bars pass through each proposal, convert that traffic to strength, merge proposals within 0.5%, and label them above/below spot.
+3. For each direction, require at least one proposal with scanner R:R ≥ 1.5 against the 1.5× ATR initial stop.
+4. Collapse nearby proposals into target zones, discard unsuitable ATR distances, and retain up to five candidates spanning near to far.
+5. Estimate each candidate's probability of reaching the target before the stop. The headline target is the most likely candidate with R:R ≥ 1.5 and probability ≥ 20%; if none clears both, the most likely candidate remains headline so a distant lottery target cannot game the gate.
+6. Apply the separate live activation floor to that headline target: production requires R:R ≥ 2.0 and probability ≥ 20%, plus the momentum/direction rules.
+7. If traded, ignore the target for exits. The initial ATR stop, 3× ATR trail and maximum hold remain authoritative.
+
+The ladder is intentionally broad and mechanical. It is not presented as
+market structure, and its transient negative level IDs must never be stored as
+chart S/R. The full-period parity run reproduced all 202,765 backtest setup
+candidates, all 1,086 qualified setups, and the production book exactly
+(Sharpe 2.03, CAGR 50.0%, max drawdown 21.4%, 321 trades). See the
+[S/R and Gate Target Ladder research](docs/research/sr-levels-and-exits.md#explicit-gate-target-ladder).
+
+**Ticker-chart diagnostic.** The optional **GTL traffic** toggle draws a
+right-edge horizontal profile aligned to the price axis. It borrows the visual
+grammar of a volume profile, but not its meaning: bar width is relative
+historical OHLCV-bar crossings at each GTL proposal, not traded volume at that
+price. Hover a bar to inspect its price, crossing count, strength and source.
+The violet profile is deliberately distinct from the Structural S/R lines and
+is off by default; it is a research aid, not another trade overlay.
+
+Below the chart, the **Production rank** strip makes the current 80/20 ordering
+snapshot explicit: a blue residual-momentum contribution and amber realized-
+volatility contribution add to the stored strategy rank, while separate
+percentile rails show each input. Only momentum carries the live activation-
+gate marker. These are cross-sectional scan percentiles, not historical chart
+indicators.
+
+### Pipelines (America/New_York)
+
+**Morning** (~02:00 ET) — data and display only, **no** qualifying R:R scan:
+
+1. **OHLCV** — latest daily bars (Alpaca); new tickers backfill ~5 years.
+2. **Sentiment** — stale names that matter (top-pick feeders, watchlist, open paper, discovery net). Display context only; the activation gate is price-only.
+3. **Market Regime** + **Regime Monitor** — breadth/trend and the v3 risk thermometer; feed no trades.
+4. **Telegram alerts** — change-driven (regime-quadrant etc.); quiet days stay quiet. Setup alerts still fire on the near-close pipeline after the scan.
+
+**Near-close** (~15:30 ET Mon–Fri) — the only full-universe qualifying observation:
+
+1. **OHLCV fetch** — refresh the in-progress day-t bar (same path as intraday).
+2. **R:R Scan** — Structural S/R, scores, Gate Target Ladder setups, residual 12‑1 + 80/20 rank. Advances post-stop gate-reset transitions; failed scans never count.
+3. **Telegram alerts** — chained immediately so manual MOC fills can still hit ~15:50/15:55.
+
+**After close** (~16:45 ET Mon–Fri):
+
+1. **OHLCV fetch** — final bar (not the partial near-close bar).
+2. **Outcome Eval** — resolve setups and auto-close paper trades (default 3× ATR trail, 30-day max hold).
+
+A failing step is logged; the pipeline continues with the next. Near-close duration is logged; warn if &gt; 10 minutes.
 
 ### Intraday — light refresh
 
-Hourly across the US session (Mon–Fri): only **OHLCV → Outcome Eval**, to keep prices current and close paper trades intraday. No scan/sentiment — the dashboard recomputes live R:R from the latest price, so fresh prices are enough.
+Hourly mid-session (Mon–Fri ~10:00–15:00 ET): only **OHLCV → Outcome Eval**, to keep prices current and close paper trades intraday. No scan/sentiment — the dashboard recomputes live R:R from the latest price.
 
 ### Other jobs
 
-Fundamentals (weekly, early Monday) · Alerts (hourly, Telegram) · Backtest (weekly) · Ticker-universe sync (daily). Deep history backfill and event study are manual-only (Admin → Jobs).

 ### From score to "top pick"
 
-1. **Composite score** — technical, S/R-quality, sentiment, fundamental and momentum sub-scores (0–100) combine into a weighted composite (weights configurable; missing dimensions re-normalize).
-2. **Setups** — the scanner builds long/short setups with ATR stops and S/R targets, then adds a confidence score, conflict flags and a target reach-probability.
-3. **Activation gate** — a setup *qualifies* only if it clears the R:R floor **and** ranks in the top residual-momentum percentile of the universe (the validated edge is long-only; the confidence floor was ablated to zero effect and defaults off).
+1. **Composite score** — technical, S/R-quality, sentiment, fundamental and momentum sub-scores (0–100) combine into a weighted composite (weights configurable; missing dimensions re-normalize). **Display and ranking only — it does not select trades.**
+2. **Setups** — the scanner builds long/short setups with a 1.5× ATR stop, generates up to five candidates from the transient Gate Target Ladder, and makes the most likely worthwhile candidate the headline target. It then adds confidence and conflict context plus a per-target reach-probability.
+3. **Activation gate** — a setup *qualifies* only if it ranks in the top residual-momentum percentile of the universe (**the actual selection**, long-only), its headline target clears the live R:R floor, **and** that target carries at least a 20% reach-probability. The confidence floor was ablated to zero effect and defaults off.
 4. **Top pick** — qualified setups are ordered by the production rank: 80% residual momentum percentile + 20% 6-month realized-volatility percentile. The #1 is highlighted on the Dashboard and labelled on the ticker page.
 
+**What the R:R and reach-probability in step 3 actually are.** They are *gate inputs*, computed from a Gate Target Ladder proposal the trade will never exit at — they exist to filter setups, not to forecast the trade you're about to take. A setup with "R:R 2.4:1, 34% reach probability" is not a claim that you'll make 2.4R with 34% probability; it's a claim that this setup cleared the screen. What actually happens to a trade is in the exit box of the diagram above, and on the "what usually happens" panel in the UI. Conflating the two is the single easiest way to misread this app.

 | Component | Verdict | Evidence |
 |---|---|---|
 | **Residual 12-1 cross-sectional momentum** (the activation gate, long-only) | **Production gate — in-sample edge** | Promoted July 2026 after the portfolio variant beat raw 80 on CAGR, Sharpe and drawdown. Raw 12-1 remains a fallback only when benchmark data is unavailable |
-| S/R setup engine (ATR stops, S/R targets, reach-probability) | **Filter/execution context, not the exit** | R:R/room-to-run still earns its keep as a filter, but S/R targets underperform the time exit. The probability model is display-only |
+| **3× ATR trailing exit** (+ 1.5× ATR initial stop, 30-day max hold) | **Production exit — best Sharpe of every exit tested** | Beat hold / SMA50 / 20-day-low / technical-40 and both take-profit variants (July 2026) |
+| **Post-stop gate reset** | **Production re-entry policy** | The initial stop always closes; the ticker must later fail the daily gate and subsequently qualify again. At the production capacity of 10: Sharpe 1.67 → 1.77, CAGR 45.2% → 48.3%, DD 24.3% → 21.6% versus immediate re-entry. [Full study](docs/research/post-stop-reentry.md) |
+| **Structural S/R** | **Human-facing context only — not a gate and not an exit** | Clean, capped zones are persisted for charts and alerts. The scanner deliberately does not read them. |
+| **Gate Target Ladder** | **Gate input only — not market structure and not an exit** | Volume-free range grid + pivots preserves the useful legacy screening behavior exactly: 1,086/1,086 qualified setups retained and identical Sharpe 2.03 / CAGR 50.0% / DD 21.4% / 321 trades. The exit never reads its target. [Full write-up](docs/research/sr-levels-and-exits.md#explicit-gate-target-ladder) |
 | Composite score + 5 dimensions | **Display/ranking only** | Sub-scores are hand-built heuristics; none has a measured IC. Note: the "momentum" *dimension* is 5/20-day ROC — NOT the validated 12-1 factor (that lives in `momentum_service`) |
 | LLM sentiment | Display + a bounded composite adjustment (± weight × 100 pts around neutral 50) | Deliberately kept out of the setup engine; no point-in-time history to validate against yet |
 | Fundamentals | Feeds composite + confidence only | Latest values only, no history — same limitation |
 | Short setups | **Excluded while the momentum gate is active** | Backtest showed shorts fight the trend and drag expectancy |
-| Expected-value gate (removed June 2026) | Degenerate — do not resurrect | Structurally favored distant lottery targets; selected *worse*-than-random setups |
+| Expected-value gate (removed June 2026) | Degenerate — do not resurrect | Structurally favored distant lottery targets; selected *worse*-than-random setups. Orphaned settings dropped in migration 020 |
+| Gate target as a take-profit (tested July 2026) | **Rejected** | Sharpe 2.04 → 1.47, CAGR halved. Win rate *rose* — it truncates the right tail where the edge lives |

 Caveats on the momentum result: in-sample, roughly one market regime, costs/slippage approximated at 0.1% per side, and residual momentum still needs SPY benchmark history to compute. The **out-of-sample proof is the forward paper-trade record**: Signals → Track Record compares live qualified expectancy against the backtest.
 
-### Current production baseline
+### Daily post-stop re-entry decision (2026-07-17)
 
-Use this as a regression guardrail for future strategy changes, not as a return promise. Backtest run: local production SQLite snapshot, 506 tickers, weekly cadence, 30-trading-day horizon, 2022-06-28 → 2026-07-01, 0.1% per-side costs, price-only SPY benchmark.
+The production policy is **normal gate reset**, evaluated with daily setup opportunities and live-like full-universe ranking. An initial stop always closes. Re-entry unlocks only after a later successful daily scan observes the ticker failing the gate and a subsequent scan observes it qualifying again. The study replayed 1,011,248 point-in-time candidate observations across 505 tickers from 2022-06-24 through 2026-07-02, with the production GTL gate, 80/20 rank, exit, fees, sizing, and 10-position capacity.
 
-| Item | Current baseline |
+| Re-entry policy | Total return | CAGR | Max DD | Sharpe | Trades |
+|---|---:|---:|---:|---:|---:|
+| Immediate | 348.4% | 45.2% | -24.3% | 1.67 | 489 |
+| **Gate reset (selected study arm)** | **388.1%** | **48.3%** | **-21.6%** | **1.77** | **472** |
+| Strict gate reset (live timing analogue) | 342.7% | 44.8% | -23.4% | 1.68 | 471 |
+| Fixed five-session cooldown | 250.8% | 36.6% | -22.2% | 1.47 | 473 |
+
+In the disjoint 2025+ book, gate reset also beat immediate re-entry (Sharpe 1.66 vs 1.55; CAGR 41.8% vs 39.3%) and the fixed five-session rule (Sharpe 1.43; CAGR 32.7%). Its lead over both survived costs of 0.2% and 0.3% per side. The result is capacity-specific: cooldown 5 won at capacity 5, while immediate had slightly higher return and Sharpe at capacity 15. Production uses capacity 10, so that is the portfolio for which this decision is valid.
+
+Those promotion numbers belong to the selected normal-reset study arm. Under the **pre-cutover** morning-scan scheduler (scan always before any outcome eval), live first-observation timing matched the stricter `strict_gate_reset` analogue (full-period Sharpe 1.68 / CAGR 44.8% / DD 23.4%). After the **near-close cutover** (2026-07), stops closed by earlier same-day intraday evals can receive a same-day fail observation at ~15:30 ET — moving live behavior **toward** the promoted `gate_reset` arm. Requalification still requires a later America/New_York trading date than the failure (`trade_policy` distinct-day guard). Full definitions and all nine policy arms: [docs/research/post-stop-reentry.md](docs/research/post-stop-reentry.md); execution evidence: [docs/research/execution-recovery.md](docs/research/execution-recovery.md).
+
+`gate_reset` and a simple `next_session` block happened to produce the same executed live-universe portfolio in this sample. Their rules are still different: this establishes that same-day re-entry was harmful here, but does not isolate a separate historical return premium from the reset condition. Gate reset was promoted because it represents a genuinely new signal episode and did not sacrifice results in the production book. Full definitions, all nine policy arms, cost/capacity sensitivity, and legacy-rank results are in [docs/research/post-stop-reentry.md](docs/research/post-stop-reentry.md); source report: [`reports/daily_reentry_matrix.json`](reports/daily_reentry_matrix.json).
+
+### Historical weekly production baseline (pre gate-reset)
+
+Use this as the historical ranking/exit regression guardrail, not as a return promise or the current re-entry-policy result. This run predates the post-stop gate reset and uses weekly entry replay, so its portfolio headline is not directly comparable with the daily matrix above. Backtest run: local production SQLite snapshot, 506 tickers, weekly cadence, 30-trading-day horizon, 2022-06-28 → 2026-07-02, 0.1% per-side costs, price-only SPY benchmark. Numbers below are the 2026-07-11 run (`reports/backtest-20260711-prod-baseline.json`) — measured *after* the primary-target probability floor shipped, which pruned lottery-target setups (1,428 → 1,089 qualified) and lifted Sharpe on all three promotion contenders.

+
+That last row is the strategy in one line: a 37.5% win rate is *fine* because the +12.9R tail pays for every −1R stop. It is also why no take-profit exists — and why the S/R "target" shown in the UI is a screening artifact, not a plan.

-| Pure high-vol 80 + 30d hold | +37.7% | -37.6% | 1.22 | 491 | Rejected: standalone volatility was too volatile |
-| Low-vol 80 + 30d hold | +0.4% | -23.1% | 0.09 | 257 | Rejected: no useful edge |
+| Legacy residual 80 + 30d hold | +49.6% | -15.8% | 2.02 | 300 | Previous production baseline. Still the shallowest drawdown of the three |
+| Residual/high-vol 80/20 + 30d hold | +51.9% | -22.2% | 2.00 | 303 | The vol tilt buys CAGR and pays for it in drawdown |
+| Residual/high-vol 80/20 + 3x ATR trail | +50.4% | -21.4% | 2.04 | 320 | Promoted: best Sharpe. The ATR trail recovers part of the drawdown the vol tilt costs |
+| Pure high-vol 80 + 30d hold | +31.6% | -34.8% | 1.12 | 476 | Rejected: standalone volatility was too volatile |
+| Low-vol 80 + 30d hold | +2.7% | -19.5% | 0.29 | 240 | Rejected: no useful edge |
+
+Read the top three honestly: the production book wins on Sharpe, not on every axis. The 80/20 vol tilt buys ~2pp of CAGR over the legacy residual-only book but costs ~6pp of drawdown, and the ATR trail hands part of that drawdown back. If drawdown ever matters more than risk-adjusted return here, legacy residual 80 + hold is the row to revisit.
 
 The conclusion is not "trade high volatility alone." Keep residual momentum as the entry gate, use realized volatility only as a small ranking tilt, and add the ATR trail as defensive exit discipline.

 Two findings future sessions must not re-litigate:
 
 - **The "inverse-vol sizing win" (July 2026) was mis-attributed — do not resurrect.** The diagnostic sized `notional = equity × 1% / vol_6m`, and the 20% notional cap bound on 95% of entries, so it actually measured "~5 positions × 20% notional each" — a concentration/risk-appetite bump economically equivalent to raising risk to 1.5%, not vol-managed sizing. Genuine inverse-vol sizing (risk budget × median-vol/vol) cuts max drawdown to −18.2% but costs ~58pp total return at flat Sharpe: a risk-preference trade, not edge.

 1. **Forward monitor the promoted strategy** — the production UI now behaves like a portfolio monitor for the current strategy, with selectable lookbacks and SPY comparison. Forward paper-trade months are the only evidence the snapshot cannot provide; the July 2026 tuning pass closed every in-sample lead. (Trailing-stop sensitivity and the max-15 capacity check are done — see the tuning table above.)

-3. **More breadth, not more history** — widening the ranked universe (e.g. `nasdaq_all`) strengthens each week's cross-section and the IC t-stat, even if only the top slice is traded. Now doubly motivated: it is also where the strong `fip_id` signal (see tuning findings) could become tradeable. (Deeper history was considered and declined.)

+"""Drop the orphaned EV-gate activation settings.
+
+``activation_min_expected_value`` and ``activation_min_target_probability`` are
+leftovers from the June 2026 EV-gate redesign (migration 009). That gate was
+superseded by the residual-momentum gate, and the current code reads neither key:
+``admin_service._ACTIVATION_FLOAT_KEYS`` exposes only ``min_momentum_percentile``,
+``min_rr`` and ``min_confidence``, and ``qualification.setup_qualifies`` gates on
+those plus the hardcoded ``MIN_TARGET_PROBABILITY`` floor.
+
+The rows are therefore inert but actively misleading: prod carries
+``activation_min_target_probability = 50.0``, so anyone reading the DB (or an
+Admin screen rendering it) would reasonably believe a 50% probability floor is
+enforced. It is not — the real floor is the 20% constant in ``qualification.py``.
+
+Reads never recreate them (``settings_store.get_value`` returns a default without
+persisting), and the current Admin write path no longer emits these keys, so the
+delete is permanent. Follows the precedent of migrations 009, 015 and 018.

+"""fundamental_snapshots.weighted_avg_diluted_shares — market-cap fallback
+
+Revision ID: 027
+Revises: 026
+Create Date: 2026-07-24 00:00:00.000000
+
+Multi-class issuers report the cover-page share count per share class. That is a
+dimensional fact and Company Facts is non-dimensional, so it is absent entirely:
+META has never tagged it, CMCSA stops in 2009, BRK-B in 2011, CHTR in 2016 (when
+the Time Warner Cable deal made it multi-class). `shares_outstanding` is
+therefore null for a large slice of the mega-cap universe, which silently removes
+both `market_cap_est` and `fcf_yield`.
+
+The weighted-average diluted count is always present (EPS requires it) and is
+consolidated across classes. Measured against issuers where the true
+point-in-time count IS available, it lands within ~0.6%: GOOGL 0.9936, MRNA
+1.0045, AAPL 0.9974, MSFT 0.9978.
+
+Stored as its own column rather than backfilled into `shares_outstanding`, so the
+point-in-time column keeps its strict meaning and the fallback stays an explicit,
+labelled read-time decision. Existing rows are null until a reparse.

+"""Market-breadth state and early-warning indicators.
 
 Breadth is a genuinely *leading* construct: a few mega-caps can keep an index
 rising while participation narrows underneath — the classic pre-top divergence.
-We measure it from the OHLCV we already store for the whole universe, so it costs
-no new data source.
+V2 measures an explicit, frozen basket rather than every ticker currently stored
+in the database.  That keeps the live series reproducible when the wider product
+universe changes.
 
 Two layers:
   - breadth = % of the universe trading above its own 200-DMA (0-100).
   - divergence = an early-warning score (0-100, high = fragile): the benchmark
-    price rising *while* breadth falls, plus a nudge for already-low breadth.
+    price holding/rising *while* breadth falls. Absolute low breadth stays in the
+    State index so it is not counted twice.
 
-This module only *computes* the indicator. It is deliberately NOT wired into the
-live regime index yet — the event study measures whether it actually leads before
-it earns any weight.
+The live monitor uses the breadth level in State and the pure divergence in
+Warning. The event study evaluates the latter chronologically.

-"""Event study: does a candidate indicator actually *lead* regime breaks?
+"""Compact chronological validation for the Regime Monitor warning score.
 
-This is a backtest-style measurement, but the unit of analysis is **events**
-(historical drawdowns), not trades. For each candidate indicator it answers:
-  - how many days of warning did it give before the break (event-centered)?
-  - at what false-alarm cost (signal-centered precision/recall vs. the base rate)?
-
-It compares the breadth-divergence early-warning candidate against a deterministic
-**coincident** price composite (the existing regime price sub-scores), so you can
-see whether the candidate crosses *earlier*. Everything is price/breadth only —
-no LLM/FRED — so the result is reproducible.
-
-Honest caveat: with only a handful of real drawdowns in ~5y, the sample is tiny
-and the numbers are noisy. Read the median lead time as an order of magnitude, and
-do NOT overfit thresholds to this history.
-
-Report is cached in a SystemSetting (mirrors ``backtest_service``); a manual job
-(Admin → Jobs) drives it.
+The study calls its outcome a 10% correction, uses the first 70% of sessions to
+freeze an 80th-percentile warning threshold, and reports alarm episodes only on
+the final 30%.  It is still labelled exploratory while the fixed breadth basket
+is reconstructed before its freeze date.

+"""Pure read-time derivation of fundamental metrics from stored snapshots.
+
+`fundamental_snapshots` stores one immutable row per accession with **cumulative
+YTD** duration facts and period-end balance-sheet instants (A3). This module
+derives everything the UI/API shows — discrete quarters, Q4, TTM, YoY growth,
+margins, leverage, dilution, and the quarter tape — at read time, per the plan's
+schema decision. No I/O, no DB: it takes an issuer's snapshot rows (ORM rows or
+any objects with the same attributes) and returns structured metrics.
+
+Rules:
+- **Amendment selection:** for each (fiscal_year, fiscal_period), the newest
+  `accepted_at` wins **per field**, falling back to the newest row that actually
+  reports one. A partial amendment (a 10-K/A adding Part III carries no financial
+  facts) must not blank the period.
+- **Discrete quarter** = YTD(Qn) − YTD(Qn−1); Q1 = YTD(Q1); **Q4 = YTD(FY) −
+  YTD(Q3)**. Any missing period → the derived value is null, never partial.

+A pipeline invocation stamps a unique run id into the task context. The scan it

+
+This is what timestamp comparison cannot provide. A manually triggered scan and

+though its batch is unrelated. Matching on a run id generated by the pipeline,
+and stamped only by the scan running inside that pipeline, removes the ambiguity.

+All access is batch (never at request time). This wraps the three SEC products
+the A3 design uses — `company_tickers.json`, `submissions/`, `companyfacts/`, and
+the daily filing index — behind one client that honors SEC's fair-access policy:

+- an identifying ``User-Agent`` with a contact email on every request (config);

+- exponential backoff + retry on 429;
+- **403 → alert and stop** (raise ``SecForbiddenError``), never a retry-loop — a

+  bucket reports an absent file (``_is_absent_archive_key``).
+
+Parsing lives here (index fixed-width, submissions pagination); DB writes and the
+snapshot mapping live in the importer. No conditional GETs — the companyfacts
+endpoint exposes no ETag/Last-Modified (verified), which is why the importer is

+"""Pure parser: SEC companyfacts -> fundamental_snapshots rows.
+
+Turns one issuer's `companyfacts` JSON (+ its submissions filing metadata) into
+per-accession snapshot rows for the filing's **primary period**, following the
+A3 design (docs/dolt-sec-a3-design.md). No I/O, no DB — unit-testable against a
+fixture and verifiable against a real companyfacts pull.
+
+The load-bearing rules (design Decision 2 + review):
+- Period identity comes from `end == submissions.reportDate`, never `fy/fp`
+  (fy/fp is the *filing's* context; comparatives inside a filing repeat it).
+  This applies to the stored `fiscal_year`/`fiscal_period` too: they are derived
+  from `reportDate` against the issuer's `fiscalYearEnd` (see `_period_identity`),
+  because SEC's fy/fp collide and invert often enough to break the quarter chain.
+- Duration facts are stored as **cumulative YTD**: pick the fact whose span
+  matches the fiscal-period-to-date length (Q1≈3mo … FY≈12mo) within tolerance.
+  If no YTD-length fact exists, store null — never a discrete masquerading as YTD.
+- Balance-sheet instants are taken at `end == reportDate`. `shares_outstanding`
+  is a single consolidated value: the cover-page `dei` fact (its own cover-date
+  `end` stored separately) if present, else `us-gaap:CommonStockSharesOutstanding`
+  at period end (e.g. Alphabet has no `dei` fact) — never a class sum or the
+  weighted-average/diluted count. Multi-class issuers report it per class, which
+  is dimensional and therefore absent from companyfacts entirely, so
+  `weighted_avg_diluted_shares` is stored alongside as an explicit fallback for
+  market cap — a separate column, never backfilled into `shares_outstanding`.
+- Cash and debt composites are aggregate-first and mutually exclusive (each
+  source tag counted at most once).
+
+`parse_snapshots` separates `skipped_filings` (no usable row produced) from
+`field_issues` (a row was produced but a field is null/ambiguous) — callers must
+not treat field issues as missing coverage.

+"""SEC fundamentals importer (workstream A, phase A3).
+
+A ``SourceImporter`` (see ``app/services/data_import.py``) that populates the
+immutable ``fundamental_snapshots`` from SEC Company Facts and back-fills
+``tickers.cik/sic/sic_description``. EDGAR-daily-index driven: it fetches
+companyfacts only for tracked issuers that filed since the last run (full-history
+backfill on the first run / for newly-added issuers). Shadow only — nothing reads
+snapshots until A4.
+
+Guardrails (design + reviews):
+- ``detect_revision`` caches the resolved universe + the exact tracked index rows
+  and composes the revision from them; ``stage`` consumes those same cached inputs
+  (it does not refetch the index/universe) so promoted data always matches the
+  computed revision.
+- Resolution is read-only in ``stage`` (proposals only); ticker writes happen in
+  ``promote`` via ``apply_ticker_updates``.
+- ``validate`` runs the **index↔Company-Facts consistency gate** before any write:
+  a tracked XBRL index accession missing from Company Facts fails the run (the two
+  are separate SEC products that can lag) so we retry rather than record a
+  null/partial snapshot. Non-XBRL amendments are skipped with a recorded reason.
+  A failure here blocks every later run (``source_max_date`` only advances on a
+  promoted run), so it names the offending filings in the alert and separates the
+  causes — ``not_in_companyfacts`` (facts lag) vs ``not_in_submissions`` (the
+  index row is absent from the issuer's own filing list, which no retry fixes).
+- **Co-registrant recovery**, because "missing from Company Facts" is often not
+  missing at all: SEC files some combined parent/subsidiary filings' XBRL under
+  the co-registrant's CIK, so the ticker-carrying parent's own file never gets
+  that accession. The daily index lists every co-registrant of an accession, so
+  the facts are found there and re-stamped to the real filer — guarded by a
+  share-count continuity check so a subsidiary's standalone numbers can never be
+  stored as the parent's. Confirmed 2026-07-27 (NEE via FPL, DOW via Dow Chemical)
+  and it is not transient: an NEE filing misattributed in 2014 is still misfiled.
+- **Bounded blocking.** Anything still unresolvable after ``MISSING_XBRL_RETRY_DAYS``
+  stops failing the whole import and enters a durable retry queue. The scheduled
+  importer retries queued accessions automatically, while the affected issuer is
+  excluded from actionable setups until its filing is recovered.
+- ``promote`` inserts snapshots ``ON CONFLICT (accession) DO NOTHING`` (immutable),
+  reports differing existing accessions, and applies ticker updates in the same
+  transaction.
+- ``reparse=True`` is the one exception to immutability, and it is deliberate:
+  it restages every accession with the current parser and **rewrites** the rows
+  that now reconstruct differently. Immutability protects SEC's record (one row
+  per accession, amendments retained) — but the stored row is *our* reconstruction,
+  so after a parser fix, keeping it is preserving a stale cache, not history.
+  Manually invoked through ``scripts/reparse_fundamentals.py``; never scheduled.

+# Dolt bulk-data integration — implementation plan
+
+Status: approved 2026-07-21, revised through four review rounds; direction: KISS
+backend, UI value first. Hand-off document for the implementing agent;
+self-contained.
+
+## Objective
+
+Replace the free-tier fundamentals APIs (FMP, Finnhub, Alpha Vantage) with bulk
+data: SEC Company Facts for fundamentals, the DoltHub earnings repo for the
+earnings calendar/history, and — later, independently — the DoltHub stocks repo for
+historical OHLCV. PostgreSQL stays the production system of record.
+
+**Delivery order: two independent workstreams.**
+
+- **Workstream A (build first):** SEC fundamentals + Dolt earnings + API v1 +
+  FundamentalsPanel + decommission FMP/Finnhub/Alpha Vantage. Valuation uses the
+  existing Alpaca closes already in `ohlcv_records`. This alone achieves the goal
+  (killing the quota-limited APIs) and delivers all the UI value.
+- **Workstream B (later, optional until needed):** replace historical OHLCV with
+  the Dolt stocks repo. The most complex machinery (4.7 GB clone, split
+  adjustment, source-bar table, reconciliation) lives here and blocks nothing in A.
+
+**Guiding principle: KISS.** Plain daily importers with staging and atomic
+promotion — no forensic replay, no permanent archive store, no conflict tables, no
+aggregate tables. Engineering budget goes into the UI (quarter trends, peer
+comparison). Deferred until a concrete need: exact source replay, point-in-time
+backtest enforcement, fundamental metrics in scoring.
+
+**Non-negotiables**
+
+- The application never queries Dolt/DoltHub or SEC at request time. All access is
+  batch import → PostgreSQL. If a sync fails or the source is unchanged, production
+  continues on the last successfully imported data.
+- Do not replace PostgreSQL with Dolt/Doltgres. Never commit to the upstream clones.
+- No owned SEC Dolt repo: SEC JSON is normalized straight into PostgreSQL.
+- Scoring **code** is unchanged, but swapping the data source changes production
+  behavior: `app/services/scoring_service.py` (~line 450) scores pe_ratio /
+  revenue_growth / earnings_surprise from `fundamental_data`, so new definitions
+  change rankings even with identical code. Cutover of `fundamental_data`
+  population requires the **score-parity gate** (phase A5) — never silently. All
+  *new* metrics are display-only.
+- Intraday (10:00–15:00), near-close (15:30) and after-close (16:45) pipelines stay
+  on Alpaca unchanged.
+
+## Data sources
+
+1. **SEC Company Facts + submissions bulk files** (free, no key; costs bandwidth,
+   CPU and disk — optimize accordingly) — XBRL facts per **issuer (CIK), not per
+   ticker**. Tickers resolve to a CIK via SEC `company_tickers.json` (multi-class
+   issuers like GOOGL/GOOG share one CIK and one set of fundamentals). Submissions
+   also supply the SIC code (peer grouping) and `acceptanceDateTime`. Handle unit
+   variants and fiscal-period alignment (derive Q4 = FY − Q1..Q3 where needed).
+   **Amendments:** retain every accession immutably; readers select the newest
+   valid `accepted_at` snapshot per reporting period at read time. No flags, no
+   mutation.
+2. **`post-no-preference/earnings`** (DoltHub) — announcement date, BMO/AMC session
+   (partial), period end, EPS estimate/actual, surprise history. Small clone.
+   `scripts/import_dolthub_earnings.py` is a research/SQLite importer — reuse its
+   normalization/alignment logic (calendar↔EPS-history monotonic alignment, SUE
+   scaling) but write a production PostgreSQL importer; do not extend the script.
+3. **`post-no-preference/stocks`** (DoltHub, **workstream B**) — daily raw OHLCV
+   (unadjusted), symbol metadata, splits, dividends. Publishes ~01:30 ET the
+   following calendar day. Clone is ~4.7 GB.
+
+**Licensing (phase A0) — DECIDED 2026-07-22:** `post-no-preference/earnings` is
+**approved for private/internal ingestion under CC BY-SA 4.0**. Conditions the A2
+importer must honor: preserve the upstream license, attribution, and transformation
+notes (retain a CC BY-SA 4.0 reference + attribution to `post-no-preference/earnings`
+and a note of the transformations applied — e.g. in a repo `NOTICE`/attribution file
+and the importer module); **no public API, bulk export, or redistribution** of the
+data; re-review licensing before any public or commercial access. The
+`post-no-preference/stocks` repo (workstream B) is **not** covered here and will be
+reviewed separately if B begins.
+
+## Schema
+
+**Migration 026 (workstream A)** — current head: `025_trade_setup_scan_run_id`:
+
+- `data_import_runs` — lean: id, source (`sec_facts` | `dolt_earnings` |
+  `dolt_stocks`), revision (Dolt commit hash, or SEC archive SHA-256), status
+  (`running`/`validated`/`promoted`/`no_op`/`failed`), source_max_date, row_counts
+  JSON, validation JSON (includes reconciliation/discrepancy summaries — no
+  separate conflicts table; details go to structured logs), started_at,
+  completed_at, error_details. One run per source at a time (Postgres advisory
+  lock keyed by source).
+- `earnings_events` — ticker_id, announce_date, session (`bmo`/`amc`/`unknown`),
+  period_end, eps_estimate, eps_actual, source, import_run_id. Unique
+  (ticker_id, announce_date). **Rescheduling:** within each promotion transaction,
+  delete this source's future-dated rows (announce_date > today) and re-insert
+  from the new snapshot, so moved or cancelled dates never linger. Past rows
+  (results) are never deleted.
+- `tickers` — add nullable `cik`, `sic`, `sic_description` (from SEC submissions /
+  `company_tickers.json`; refreshed by the SEC import; multi-class tickers share
+  values). The only ticker↔issuer join point.
+- `fundamental_snapshots` — **CIK-keyed, one immutable row per accession**: cik,
+  accession (unique), form, filed_date, **accepted_at** (kept although PIT
+  enforcement is deferred — one timestamp now vs painful retrofit later),
+  **period_start, period_end, fiscal_year, fiscal_period** (the filing's own
+  `dei`/`us-gaap` period identity — required to align non-calendar fiscal years and
+  to derive discrete quarters from cumulative facts), and the **price-independent
+  raw facts** so metrics are recomputable. **Store facts as the filing reports
+  them, not as derived quarters:** duration facts (revenue, net income, diluted EPS,
+  CFO, capex, EBITDA inputs) retain the filing's normalized **cumulative YTD/FY**
+  value for the (period_start → period_end) span; balance-sheet facts (cash+ST
+  investments, total debt, shares outstanding) are **period-end** values.
+  ``shares_outstanding`` is a point-in-time count
+  (``dei:EntityCommonStockSharesOutstanding``), not the weighted-average diluted
+  share count — both consumers (est. market cap, YoY dilution) want a
+  point-in-time value. **Nothing
+  derived is frozen into a row:** discrete quarters (10-Q YTD deltas, Q4 = FY −
+  Q1..Q3), TTM, YoY and the four-period metric histories are all computed **at read time** by
+  picking the newest valid accepted_at snapshot for *each* required period — so
+  non-calendar fiscal years resolve correctly and a later amendment to a prior
+  quarter is reflected automatically without ever storing a stale derived quarter.
+  Readers pick the newest valid accepted_at per period; history powers the UI
+  reference comparisons and deterministic reads.
+- Keep `fundamental_data` (`app/models/fundamental.py`) as the latest-value compat
+  cache, repopulated by the daily SEC job — but only after the phase-A5 parity
+  gate.
+
+**Migration 027 (workstream B, written when B starts):**
+
+- `ohlcv_source_bars` — source-truth bar table, required because `ohlcv_records`
+  allows one row per (ticker_id, date) (`app/models/ohlcv.py:12`) and Alpaca
+  ingestion upserts it in place (`app/services/price_service.py:82`) — Dolt and
+  Alpaca bars cannot coexist there. Holds **Dolt raw (unadjusted) bars only** —
+  Alpaca bars are already split-adjusted at the provider (`app/providers/alpaca.py:77`
+  requests `Adjustment.SPLIT`) and live exclusively in `ohlcv_records`. Columns:
+  source (`dolt`), adjustment (`raw` — explicit), ticker_id, date, OHLCV,
+  import_run_id; unique (source, ticker_id, date). Changed bars are counted in the
+  run's validation JSON and logged before overwrite.
+- `corporate_actions` — ticker_id, type (`split`/`dividend`), ex_date,
+  ratio/amount, source, import_run_id. Unique (ticker_id, type, ex_date).
+- `ohlcv_records` — add nullable `import_run_id` FK and `source` text (default
+  `'alpaca'`).
+
+## Import framework
+
+Every importer: idempotent per revision (same Dolt commit / archive checksum →
+`no_op`, zero row changes); stage into a representation outside the live tables
+first (in-memory for the small workstream-A sources; a file/table handle is fine
+if workstream B ever needs it); promotion in one transaction;
+safe to retry; a failed or unchanged run leaves the current dataset untouched.
+Record every attempt in `data_import_runs`.
+
+**SEC access requirements (operational safeguards, per SEC fair-access policy):**
+send an identifying `User-Agent` with a contact email on every request; stay far
+below the 10 req/s limit (the bulk endpoints need only a handful of requests per
+run); exponential backoff on 429; a 403 means the User-Agent or request pattern is
+wrong — alert and stop, never retry-loop. See SEC developer resources
+(https://www.sec.gov/about/developer-resources).
+
+**Reproducibility scope (deliberately limited):** the normalized snapshots in
+PostgreSQL *are* the durable record. Keep only the last ~2 SEC archives on disk for
+debugging. Byte-level replay of old runs is out of scope until a concrete need.
+
+Dolt access: `dolt pull` on the persistent clone, record the resulting commit hash,
+read via `dolt sql -r csv` (no long-running sql-server). **The scheduler shares one
+event loop with the API** (`app/scheduler.py:73`) — run dolt/unzip/download
+subprocesses via `asyncio.create_subprocess_exec` (or an executor), never blocking
+calls. Check free disk space before pulling; alert and skip if below threshold.
+
+**Deployment constraints:** deploy is `rsync --delete` of the repo tree
+(`.gitea/workflows/deploy.yml:127`), so clones and archives must live **outside the
+deployment path** — an env-configured persistent directory (e.g.
+`DOLT_DATA_DIR=/var/lib/signal-platform/dolt`). The dolt binary is a new prod
+runtime dependency: install it once with the version-pinned provisioner in
+`deploy/provision_fundamentals.sh`; operational steps are in
+`docs/fundamentals-deployment.md`. The clone is reproducible from DoltHub; the
+normalized PostgreSQL rows remain part of the normal database backup.
+
+**Validation gates (block promotion, raise an alert via the existing system-events
+path):** source freshness as expected; tracked-universe coverage; no duplicate
+business keys; fundamental units/periods consistent; row-count deltas within
+reason; upstream schema change stops promotion. Workstream B adds: OHLC sanity
+(high ≥ open/close/low, low ≤ open/close/high, volume ≥ 0); no unexplained split
+discontinuities.
+
+**Split adjustment (workstream B):** `ohlcv_source_bars` + `corporate_actions` are
+the source of truth; canonical `ohlcv_records` is *generated* from them to match
+Alpaca `Adjustment.SPLIT`, selecting only adjustment = `raw` rows as input so
+adjustment is applied exactly once. A newly published split rewrites the symbol's
+entire adjusted history — treat whole-symbol rewrites as a normal import event
+(exempt that symbol from the row-count-delta gate for that run) and stamp rows with
+the import_run_id (a backtest↔prod parity guard exists; changed history changes
+backtests).
+
+## Scheduling (`app/scheduler.py` — `SCHEDULE_DEFAULTS` / `_CRON_JOBS`, ~line 1451)
+
+Follow the existing pattern: cron strings in SystemSettings via
+`app/services/settings_store.py`, day-of-week as names never numbers, logging via
+`_log_event`.
+
+Workstream A:
+
+- Dolt earnings import: daily ~02:30 ET (with the future-row replacement above).
+- **SEC fundamentals job: daily ~04:00 ET.** One job, three steps:
+  (a) detect a composite revision from the latest EDGAR daily-index date, the
+  exact tracked index rows, and the tracked-universe fingerprint — an unchanged
+  revision is a `no_op` before Company Facts are fetched;
+  (b) when changed, fetch and parse Company Facts only for tracked-universe CIKs
+  that filed, plus full available history for the first run or a newly added
+  issuer, through validation→atomic promotion. Universe resolution and the exact
+  index inputs are cached during revision detection and reused during staging;
+  CIKs are resolved from `company_tickers.json` without writes until promotion;
+  (c) **always, locally, and only after production activation** (the phase-A5
+  parity approval): refresh the legacy `fundamental_data` fields and mark affected
+  cached fundamental scores stale. **Sources differ per field** — do not assume all
+  five come from SEC: `pe_ratio` and `market_cap` from the newest valid snapshots ×
+  latest PostgreSQL close, each with its own formula — `pe_ratio` = latest close /
+  TTM diluted EPS; `market_cap` = issuer-wide shares outstanding × latest close;
+  `revenue_growth` from the snapshots alone; `earnings_surprise` and
+  `next_earnings_date` from `earnings_events` (the Dolt earnings feed — these two do
+  not exist in SEC facts). Before activation the job imports snapshots only
+  (shadow). Step (c) must run identically when SEC is unreachable — prices move
+  daily even when filings don't, and the earnings-derived fields already live in
+  PostgreSQL.
+  **The new API valuation object is not stored anywhere** — it is computed at
+  request time (below). No valuation cache or table exists.
+
+Workstream B:
+
+- Dolt OHLCV+splits pull/import: `0 2 * * tue-sat` ET. If source_max_date is not
+  fresh, retry hourly until ~06:00, then give up quietly. After a successful
+  import, reconcile the previous session's Dolt-derived bars against the Alpaca
+  bars; summary into the run's validation JSON, details to logs.
+- Move `schedule_daily_pipeline_cron` (morning refresh) from `0 2 * * *` to
+  `0 3 * * *` (only needed once the 02:00 slot is taken by the OHLCV pull).
+  **Late Dolt publication is a non-event:** the canonical scan runs at 15:30 on
+  Alpaca, so the morning pipeline runs normally even when the import hasn't
+  landed — no gating, no defensive coupling.
+
+## Metrics catalog (curated — TTM basis)
+
+Snapshots store **price-independent per-period facts** (the "snapshot" column below
+means *derived from stored snapshots, assembled across periods at read time* — see
+Schema — not frozen at import); price-dependent ratios are never frozen into
+snapshots and have **no storage location at all**: the API computes
+them at request time from the stored snapshots + the latest `ohlcv_records` close
+(both already in PostgreSQL, so this works identically when SEC is unreachable).
+The only stored price-dependent values are the legacy `fundamental_data` fields
+that scoring already reads, refreshed daily by step (c) after activation.
+
+| Metric | Definition | Where computed |
+|---|---|---|
+| Revenue growth YoY | TTM revenue vs prior TTM | snapshot |
+| EPS growth YoY | TTM diluted EPS vs prior TTM | snapshot |
+| Operating margin + 4q trend | TTM operating income / revenue | snapshot |
+| FCF margin | (TTM CFO − capex) / revenue | snapshot |
+| Net debt | total debt − (cash + ST investments); positive = net debt | snapshot |
+| Net debt / EBITDA | net debt / TTM EBITDA | snapshot |
+| Share count Δ YoY | shares outstanding vs year ago | snapshot |
+| Trailing P/E | price / TTM diluted EPS | request time |
+| FCF yield | TTM FCF / est. market cap | request time |
+| Est. market cap | issuer-wide shares outstanding × ticker price | request time |
+| Earnings surprise history | last 4+ from `earnings_events` | query |
+
+**Market cap is an estimate** (issuer-wide shares outstanding × one ticker's price —
+approximate for multi-class issuers). Share count comes from a single consolidated
+value, not a class sum: prefer the one `dei:EntityCommonStockSharesOutstanding`
+cover-page fact; if absent (e.g. Alphabet) fall back to
+`us-gaap:CommonStockSharesOutstanding` at period end. companyfacts is
+non-dimensional, so class-specific facts can't be summed reliably — never do that,
+and never substitute weighted-average/diluted shares; if conflicting values remain,
+store null. Label it "est." in the UI and round aggressively rather than withholding
+it; false precision is the failure mode, not the approximation.
+
+**Units follow existing app conventions:** percentages are percentage points
+(21.0 = 21%), P/E and net-debt/EBITDA are multiples, market cap and net debt are
+dollars.
+
+Deliberately **excluded**: ROIC (invested-capital/NOPAT normalization too noisy),
+gross margin (COGS tagging too inconsistent), any new composite score.
+
+## Peer comparison (read-time only)
+
+- Peer group = tracked-universe issuers sharing the **first two SIC digits**,
+  **deduplicated by CIK** — GOOG and GOOGL are one issuer, one observation, in
+  medians, percentiles and peer_count.
+- Computed at read time from current snapshots — no aggregate tables until
+  performance demonstrates a need.
+- Medians exclude null/invalid values. **Fewer than 5 valid peer issuers → omit
+  the peer result entirely** rather than showing a misleading universe comparison.
+- Percentile direction respects metric polarity (higher-is-better for FCF yield,
+  lower-is-better for P/E and leverage).
+
+## API contract (additive v1)
+
+Every existing top-level field is preserved unchanged (name, type, position) —
+backend and frontend ship independently, no breaking interval. New objects, exact
+names and types:
+
+```jsonc
+{
+  // ...all existing legacy fields, unchanged...
+  "earnings": {
+    "next": {"date": "YYYY-MM-DD", "session": "bmo|amc|unknown", "days_until": 12} | null,
+    "recent": [   // newest first, max 4, may be empty
+      {"announce_date": "YYYY-MM-DD", "period_end": "YYYY-MM-DD|null",
+       "eps_estimate": 1.02|null, "eps_actual": 1.10|null, "surprise_pct": 7.8|null}
+    ]
+  },
+  "metrics": [    // fixed row set — every key always present, value null when unavailable
+    {
+      "key": "revenue_growth_yoy",   // revenue_growth_yoy | eps_growth_yoy | operating_margin |
+                                     // fcf_margin | net_debt | net_debt_to_ebitda | share_count_change_yoy
+      "value": 18.0,                 // number | null — pp / multiples / dollars per units above
+      "history": [                   // oldest→newest, max 4 points, [] when unavailable

+      ],
+      "industry": {                  // object | null — null when < 5 valid peer issuers (CIK-deduped)
+        "label": "SIC 73 peers",     // truthful 2-digit group label — grouping IS 2-digit,
+                                     // so no 4-digit description like "Prepackaged Software"
+        "median": 11.0,
+        "favorable_percentile": 82,  // 0-100, polarity-aware (higher = more favorable)
+        "peer_count": 12             // issuers, not tickers
+      },
+      "period_end": "YYYY-MM-DD|null",
+      "filed_date": "YYYY-MM-DD|null",
+      "source": "sec|dolt|legacy_api"
+    }
+  ],
+  "valuation": {  // object | null (null until SEC snapshots exist, phase A3); same industry sub-object rules
+    // computed at REQUEST TIME from stored snapshots + latest PostgreSQL close —
+    // no valuation cache or table; unaffected by SEC availability
+    "pe": 29.2|null, "fcf_yield": 3.8|null,
+    "market_cap_est": 1.2e9|null,    // estimated — UI labels "est."
+    "pe_industry": {...}|null, "fcf_yield_industry": {...}|null,
+    "price_date": "YYYY-MM-DD"       // close used for the ratios
+  }
+}
+```
+
+Null/freshness semantics: absent data is `null` with the row still present (the UI
+shows "n/a", never hides rows); every metric carries its own source, period and
+filing date — no panel-wide source label. The objects may serve partial data during
+rollout (e.g. `earnings` live, `metrics` still `legacy_api`); the shape never
+changes.
+
+## UI — `frontend/src/components/ticker/FundamentalsPanel.tsx`
+
+One distinctive visual device — the **Reference Rails** — in an otherwise restrained
+panel. Preserve the app's dark glass styling and numeric typography.
+
+```

+- Margins (latest vs mean of prior periods, pp): ≥ +1.0 → "improving";
+  ≤ −1.0 → "deteriorating"; else "stable" (phrased "above/below own average"
+  where the layout calls for it).
+- Share count YoY: > +1.0% → "N% dilution"; < −1.0% → "buying back"; else "flat".
+- Peer-relative: favorable_percentile ≥ 60 → favorable ("above peers");

+- Header sentence: join the growth read, margin read and peer-relative valuation

+  · margins stable · valuation above industry median"). **Segment sources are
+  fixed:** growth = revenue growth read; margins = operating margin read;
+  valuation = P/E peer-relative read, falling back to FCF yield when P/E is null.
+  This keeps the header unambiguous when sibling metrics (EPS vs revenue growth,
+  P/E vs FCF yield) point in different directions.
+
+## Decommissioning (end of workstream A)
+
+Remove completely: FMP (`app/providers/fmp.py`), Finnhub + Alpha Vantage
+(`app/providers/fundamentals_chain.py`), their config keys (`app/config.py`), and
+their wiring in `app/scheduler.py`, `app/routers/ingestion.py`,
+`app/services/ticker_universe_service.py`. Retain: Alpaca (prices), FRED,
+sentiment provider, Telegram. Note: decommissioning does **not** depend on
+workstream B — Alpaca remains the price source throughout.
+
+## Rollout
+
+**Workstream A:**
+
+- A0. License review **DONE** (earnings approved for private/internal use under
+  CC BY-SA 4.0, no redistribution — see Licensing above). The Dolt version,
+  persistent `DOLT_DATA_DIR`, clone, and production checks are captured in
+  `deploy/provision_fundamentals.sh` and `docs/fundamentals-deployment.md`.
+- A1. Migration 026, import-run framework.
+- A2. Earnings ingestion in shadow (writes `earnings_events`, prod untouched);
+  verify forward-calendar coverage and rescheduling behavior.
+- A3. SEC daily job in shadow (writes `fundamental_snapshots`). **Primary technical
+  risk here: Q4 derivation and fiscal-period alignment** — non-calendar fiscal years,
+  restatements/amendments, and XBRL unit/dimension variants; budget accordingly.
+- A4. API v1 + FundamentalsPanel + peer comparison — served from snapshots and
+  earnings_events, independent of the scoring cutover (the additive API supports
+  partial data). UI value ships before anything touches scoring inputs.
+- A5. **Score-parity gate** → `fundamental_data` cutover: compute candidate
+  pe_ratio/revenue_growth/earnings_surprise from SEC/Dolt side by side with the
+  API values across the tracked universe, report per-field deltas and resulting
+  fundamental-score/ranking changes, require explicit approval. Definition
+  changes (e.g. TTM vs provider convention) called out, not averaged away.
+  **Status 2026-07-24: the gate has been exercised and the evidence supports
+  approval** — see the handoff section below. Step (c) is implemented behind the
+  default-off `fundamental_data_sec_dolt_cutover_enabled` SystemSetting; the
+  remaining production action is flipping that switch on and observing it.
+- A6. Remove FMP/Finnhub/Alpha Vantage; keep monitoring + manual fallback.
+
+**Workstream B (independent, start when wanted):**
+
+- B0. Stocks clone (~4.7 GB) provisioned; migration 027.
+- B1. OHLCV + split adjustment in shadow (writes `ohlcv_source_bars` only; Alpaca
+  keeps owning `ohlcv_records`); historical backfill.
+- B2. Reconciliation window (≥ 2 weeks) vs Alpaca; review validation summaries.
+- B3. Promote Dolt as historical OHLCV source (canonical rebuilt from raw source
+  bars + splits); morning pipeline → 03:00.
+
+## Test plan
+
+- Daily SEC job: changed revision imports; unchanged conditional-HTTP check is a
+  `no_op` with zero downloads and zero row changes; validation failure leaves
+  production untouched; source unavailable still runs the local
+  `fundamental_data` refresh (step c, post-activation); before activation the job
+  never writes `fundamental_data`.
+- Valuation endpoint returns identical values with SEC reachable and unreachable
+  (pure PostgreSQL computation); no valuation rows exist in any table.
+- Multi-class tickers resolve to the same CIK snapshots; peer medians and
+  peer_count are CIK-deduplicated (GOOG+GOOGL = one observation).
+- Earnings rescheduling: a moved future date replaces the old row atomically; a
+  cancelled date disappears; historical results are never touched.
+- Amendment selection: for a period with multiple accessions, the newest valid
+  accepted_at wins at read time; older rows remain unchanged.
+- History arrays are chronological, ≤ 4 points.
+- Percentage-point units stay compatible with existing formatters and scoring
+  inputs.
+- Deterministic reads: threshold boundary cases (exactly +2.0pp, exactly 60th
+  percentile) resolve per the stated rules; header uses identical outputs and
+  falls back from P/E to FCF yield for the valuation segment when P/E is null.
+- Peer comparison disappears below 5 peer issuers; favorable-percentile direction
+  correct for both polarities.
+- Workstream B: split-adjusted OHLCV matches Alpaca on representative normal /
+  split / reverse-split symbols.
+- UI states: positive, adverse, neutral, insufficient history, insufficient
+  peers; mobile layout; non-color accessibility.
+- Unit, integration, scheduler and frontend suites pass.
+
+## Acceptance criteria
+
+- App works normally with Dolt/DoltHub/SEC unreachable.
+- Re-running the same revision: zero duplicate or changed rows.
+- **Upcoming earnings dates present and timely for the tracked universe** — the
+  forward calendar is the hardest thing to replace and gates decommissioning.
+- Coverage meets the tracked-universe target; scheduler runs cleanly with
+  FMP/Finnhub/AV keys removed from the environment.
+- Score-parity diff reviewed and approved before `fundamental_data` cutover.
+- Scheduled imports never block the API event loop.
+
+## Handoff — remaining work after the A5 parity investigation (2026-07-24)
+
+The 2026-07-23 parity report surfaced coverage gaps and wrong values; a nine-pass
+investigation traced every one to parser/identity bugs (not source data), fixed them,
+and reparsed production twice. Full evidence trail:
+`reports/fundamentals-parity-20260723-findings.md` (root causes, decisions, validation)
+plus the before/after reports (`fundamentals-parity-20260723T…` / `…20260724T….json`).
+Post-fix: candidate scores 504 of 511 vs legacy's 507 (gap = PSKY/Q new registrants +
+FITB, all explained); revenue-growth agreement 0.0038 median abs delta where both exist.
+Dennis reviewed the evidence 2026-07-24 and directed proceeding to cutover.
+
+**Task 1 — A5 activation (IMPLEMENTED 2026-07-24; production switch remains).** The
+post-activation local refresh of `fundamental_data` derives `pe_ratio` and
+`market_cap` from newest valid snapshots × latest PostgreSQL close, `revenue_growth`
+from snapshots, `earnings_surprise`/`next_earnings_date` from `earnings_events`; mark
+affected cached fundamental scores stale; must run identically when SEC is unreachable.
+It consumes `fundamentals_derivation.derive()` outputs, NOT raw snapshot fields —
+that path carries the split guard (`ttm_diluted_eps`
+nulls when contaminated, with `ttm_diluted_eps_caveat`) and the multi-class share
+fallback (`shares_outstanding` + `shares_outstanding_estimated`). Parity and activation
+share the same candidate builder. Activation is the explicit
+`fundamental_data_sec_dolt_cutover_enabled` SystemSetting and defaults off. It is
+managed by the **Fundamentals data source** card in Admin → Settings; while active,
+the weekly legacy collector skips itself so it cannot overwrite the SEC/Dolt cache.
+See `docs/fundamentals-deployment.md` for the production flip and rollback procedure.
+
+**Task 2 — A6 decommissioning.** After a short observation window: remove
+FMP/Finnhub/Alpha Vantage providers, config and env keys; keep monitoring + manual
+fallback. Gated by the acceptance criteria above — especially forward-calendar
+timeliness from `dolt_earnings` (its `source_max_date` ran ~5 weeks ahead as of
+2026-07-23, which passes).
+
+**Known caveats to carry (documented in the findings report, not bugs to fix):**
+- KLAC-class post-filing splits: P/E wrong until the next 10-Q; undetectable from
+  snapshots. Workstream B's `corporate_actions` table is the natural future fix.
+- BRK-B: no share count exists anywhere in companyfacts → no market cap, correctly.
+- FITB: unscored (split guard + no taggable revenue) — the one name that lost its
+  score relative to legacy; composite renormalises.
+- Share-change guard at 25% nulls P/E for stock-funded M&A too (COF, WAT…);
+  revisit only if the ~3% universe hit-rate proves painful.
+- `sec_cik_overrides` SystemSetting pins XOM → 34088 (applied in prod); the
+  `no_xbrl_filings` SystemEvent says when a new pin is needed.
+- After any future parser change, stored rows need `scripts/reparse_fundamentals.py`
+  (dry-run default; `--apply` rewrites) — snapshots are otherwise immutable.
+
+## Deferred (explicitly, until a concrete need appears)
+
+- Workstream B itself is deferred relative to A and blocks nothing in A.
+- Exact byte-level source replay of historical imports; permanent archive store.
+- Point-in-time backtest enforcement (`accepted_at` is stored now; derivation and
+  backtest visibility rules are built only when fundamentals enter
+  scoring/backtesting).
+- Fundamental metrics in the score; sector-relative scoring.
+- Aggregate/rollup tables for peer statistics.
+- Any valuation cache or table (request-time computation from snapshots + latest
+  close suffices).
+- A dedicated conflicts table (validation JSON + logs suffice).

+# A3 design — SEC fundamentals importer
+
+Status: **design APPROVED 2026-07-22 — three decisions signed off (daily-index
+fetch, primary-period-only snapshots, full-history backfill) + four review
+correctness fixes folded in (composite revision incl. universe fingerprint;
+submissions pagination shards for full history; index↔Company-Facts consistency
+gate; insert-only immutability with discrepancy reporting; deterministic cash/debt
+composition). Ready to implement.**
+Companion to `docs/dolt-integration-plan.md` (workstream A, phase A3). Grounded in
+live SEC data probes (Apple CIK 0000320193, company_tickers, submissions, daily-index).
+
+## Objective (unchanged from the plan)
+
+Populate `fundamental_snapshots` (CIK-keyed, one immutable row per accession)
+and `tickers.cik/sic/sic_description` from SEC data, as a `SourceImporter`
+plugging into the A1 framework. Shadow only (A3): nothing reads snapshots until
+A4; `fundamental_data` is untouched until the A5 parity gate. All new metrics
+are display-only.
+
+## What the SEC data actually looks like (probed, not assumed)
+
+`data.sec.gov/api/xbrl/companyfacts/CIK##########.json` — one JSON per **issuer
+(CIK)** aggregating every period across every filing. Shape:
+`facts.us-gaap.<Concept>.units.<unit>[] = {start, end, val, fy, fp, form, filed, accn, frame}`.
+
+Ground-truth findings that drive the design:
+
+1. **`fp` is only `Q1|Q2|Q3|FY` — there is no `Q4`.** Q4 must be derived.
+2. **`fy`/`fp` are the *filing's* fiscal context, not each fact's period.** Proven:
+   Apple's FY2019 10-K carries a discrete Q3-FY2018 revenue fact
+   (`start 2018-07-01, end 2018-09-29, val 62.9B`) tagged `fp=FY` — it's a
+   comparative. **Period identity lives in `(start, end)` + the filing's
+   `reportDate`, never in `fp/fy`.** Selecting values by `fp` would silently mix
+   comparatives into the wrong period.
+3. SEC provides **both** discrete 3-month facts **and** YTD-cumulative facts
+   (Apple Q2 FY26: YTD `254,940` over 6mo *and* discrete `111,184` over 3mo;
+   `143,756 + 111,184 = 254,940`). This confirms the stored-YTD schema: store
+   cumulative YTD per filing, derive discretes/Q4/TTM at read time.
+4. Instant facts (`dei:EntityCommonStockSharesOutstanding`) end on the **cover
+   date** (2026-04-17), which differs from `period_end` (2026-03-28) → the
+   `shares_outstanding_date` column added in migration 026.
+5. **No conditional-GET support:** the companyfacts endpoint returns no `ETag`
+   and no `Last-Modified`. AAPL's file is 3.75 MB. So ~505 unconditional fetches
+   ≈ 0.5–1.5 GB *per run* — the plan's "conditional HTTP no-op" is impossible on
+   this endpoint. This is the fact that decides the fetch strategy (below).
+6. `submissions/CIK##########.json` supplies `sic`, `sicDescription`,
+   `fiscalYearEnd` (e.g. `0926`), and per-accession `reportDate` +
+   `acceptanceDateTime` — the keys for period selection and `accepted_at`.
+7. `company_tickers.json` uses **dash** tickers (`BRK-B`, `BRK-A`) and maps
+   `GOOGL`/`GOOG` to the **same** `cik_str` (1652044). The ticker→CIK join reuses
+   the earnings importer's `normalise_symbol` (dot→dash), so both sides match.
+
+## Decision 1 (APPROVED) — fetch strategy: EDGAR daily-index driven
+
+**Plan said** bulk `companyfacts.zip` + ETag no-op. **Reality:** the data.sec.gov
+endpoints expose no validators, and the bulk zip is multi-GB and changes ~daily
+(all of EDGAR), so ETag would rarely match → near-daily multi-GB download to get
+505 issuers. Per-CIK *conditional* fetch is impossible (finding 5). Per-CIK
+*unconditional* is 0.5–1.5 GB every night.
+
+**Recommended:** drive off the **EDGAR daily-index** (`daily-index/YYYY/QTRn/
+form.YYYYMMDD.idx` — fixed-width Form/Company/CIK/Date/accession, ~3300 rows/day,
+confirmed). Each run:
+
+- `detect_revision` → a **composite revision**, not just the date:
+  `latest-index-date` + a hash of the index content processed this run + a
+  **fingerprint of the tracked symbol→CIK set**. The CIK fingerprint is essential:
+  a newly added ticker changes the revision and forces a run, so a new ticker is
+  never `no_op`'d away or starved waiting for its issuer to file. Equal composite
+  revision → `no_op`.
+- **No backfill sentinel.** The *absence of a prior promoted run* is what triggers
+  the initial full-history backfill; `source_max_date` records the processed index
+  date each run.
+- `stage` → for each index date since the last processed one, parse the form
+  index, keep rows where `form ∈ {10-K, 10-Q, 10-K/A, 10-Q/A}` **and** CIK ∈
+  tracked set, then fetch `companyfacts/CIK.json` for **only those few issuers**
+  and extract their newly-reported period(s). Most nights this is a handful of
+  issuers → near-zero transfer, respectful of SEC fair-access.
+- **First run (backfill)**: no prior promoted run → fetch companyfacts for all
+  tracked CIKs once (~1 GB one-time) and seed **full** history. Full history needs
+  the paginated submissions shards — see "CIK resolution" below.
+
+Why this over the alternatives: transfer scales with *filings*, not with all of
+EDGAR or with the universe size every night; it restores the revision/no_op
+model; and it's the lightest load on SEC. Cost: daily-index parsing + date
+bookkeeping (store last-processed index date in `data_import_runs` /
+settings). **This deviates from the plan's "bulk zip" — requesting sign-off.**
+
+## Decision 2 (APPROVED) — snapshot mapping: primary-period, YTD, immutable
+
+One `fundamental_snapshots` row per accession, representing the filing's
+**primary current period only** (not its comparatives):
+
+- **Select the primary period by `end == submissions.reportDate[accn]`** (finding
+  2), *not* by `fp/fy`. `fiscal_period` label comes from the filing's own `fp`
+  (a 10-Q's own `fp` matches its current quarter; a 10-K → `FY`);
+  `fiscal_year`/`period_start`/`period_end` from the selected facts + submissions.
+- **Duration facts → cumulative YTD.** For each concept, pick the duration fact
+  with `accn == thisFiling`, `end == reportDate`, and `start ≈ fiscal-year start`
+  (derived from `fiscalYearEnd`), sanity-checked by span length (Q1≈3mo, Q2≈6mo,
+  Q3≈9mo, FY≈12mo). **If the YTD fact is absent, store null — never a discrete
+  masquerading as cumulative** (that would poison read-time differencing).
+- **Balance-sheet instants → at `end == reportDate`.** `shares_outstanding` is
+  the exception: prefer the `dei:EntityCommonStockSharesOutstanding` cover-page
+  fact and store *its own* `end` in `shares_outstanding_date` (cover date ≠
+  period_end); when there is no dei fact (e.g. Alphabet) fall back to
+  `us-gaap:CommonStockSharesOutstanding` at `reportDate`. A single consolidated
+  value — never a class sum (companyfacts is non-dimensional) nor
+  weighted-average/diluted; conflicting values → null.
+- **Amendments:** a real `10-K/A` / `10-Q/A` is a new accession → a new immutable
+  row for the same `(cik, fy, fp)`; readers pick the newest valid `accepted_at`.
+- **Out of scope (stated, not silent):** restatements that appear *only* as
+  comparatives inside a later normal filing are **not** captured — only a real
+  amendment updates a prior period. This narrows the plan's "newest accepted_at
+  per period" to amendment-driven updates; a deliberate KISS boundary.
+- **Immutable means insert-only, not upsert.** `promote` **inserts** new accession
+  rows with `ON CONFLICT (accession) DO NOTHING`. An accession never mutates: if a
+  re-fetch reconstructs *different* values for an accession already stored, that is
+  a **discrepancy to report** (into `validation_json` + a system event), never a
+  silent overwrite, and the original `import_run_id` is never replaced. (Ordinary
+  updates arrive as a *new* amendment accession, which is a new row.)
+
+## Read-time derivation (constrains the importer; built in A4)
+
+From the per-accession YTD rows, all at read time (newest `accepted_at` per
+period), following the schema decision already in the plan:
+
+- discrete quarter = YTD(Qn) − YTD(Qn−1); **Q4 = FY − YTD(Q3)**.
+- TTM = sum of the trailing four discrete quarters (e.g. TTM@Q2 = FY(prev) +
+  YTD(Q2) − YTD(Q2 prev year)).
+- YoY = period vs same period a year earlier.
+- **Hard rule the importer must enable: any missing period in a run → the derived
+  value is `null`, never a partial number.** So the importer must aim for
+  complete consecutive quarter runs per issuer and report gaps.
+
+## Metric tag catalog (prioritized us-gaap tags + fallbacks)
+
+Tagging is inconsistent across issuers (the plan's known risk). Each metric
+resolves through an ordered tag list; first present wins; unit-checked.
+
+| Snapshot field | Primary tag | Fallbacks | Unit |
+|---|---|---|---|
+| revenue | `RevenueFromContractWithCustomerExcludingAssessedTax` | `Revenues`, `SalesRevenueNet` | USD |
+| net_income | `NetIncomeLoss` | — | USD |
+| operating_income | `OperatingIncomeLoss` | — | USD |
+| diluted_eps | `EarningsPerShareDiluted` | — | USD/shares |
+| cfo | `NetCashProvidedByUsedInOperatingActivities` | `...ContinuingOperations` | USD |
+| capex | `PaymentsToAcquirePropertyPlantAndEquipment` | `PaymentsToAcquireProductiveAssets` | USD |
+| depreciation_amortization | `DepreciationDepletionAndAmortization` | `DepreciationAmortizationAndAccretionNet`, `DepreciationAndAmortization` | USD |
+| cash_and_st_investments | see composition rule | — | USD |
+| total_debt | see composition rule | — | USD |
+| shares_outstanding | `dei:EntityCommonStockSharesOutstanding` | — | shares |
+
+**Composite fields — deterministic, aggregate-first, no double counting.** Each
+source tag contributes at most once:
+
+- `cash_and_st_investments` = `CashAndCashEquivalentsAtCarryingValue`
+  **+ short-term investments**, where ST investments = the **first present** of
+  [`ShortTermInvestments`, `MarketableSecuritiesCurrent`] — never both summed.
+- `total_debt` = **long-term component + short-term component**, where
+  - long-term = first present of [`LongTermDebt` (the aggregate, already includes
+    current + noncurrent portions), **else** (`LongTermDebtNoncurrent` +
+    `LongTermDebtCurrent`)];
+  - short-term borrowings = first present of [`ShortTermBorrowings`,
+    `CommercialPaper`] (0 if neither).
+  So the long-term aggregate and its components are mutually exclusive, and CP vs
+  short-term-borrowings is a single pick — nothing is counted twice.
+
+EBITDA (for net-debt/EBITDA) is derived at read time = operating_income + D&A.
+Concepts absent for an issuer → that field is null (display-only; no synthesis).
+The exact tag lists live as named constants, tunable without touching logic.
+
+## Fiscal-period identity
+
+`fiscalYearEnd` (MMDD from submissions) anchors the fiscal-year start for YTD
+span checks and Q4 derivation. Non-calendar fiscal years (Apple's Sept) are
+handled because we key on `(start, end)` + `reportDate`, not calendar quarters.
+`fiscal_year`/`fiscal_period` are stored from the filing's own `fy`/`fp` for its
+primary period (safe — a filing's own context is correct for its current period).
+
+## CIK resolution & tickers backfill
+
+- From `company_tickers.json`: `normalise_symbol(ticker) → cik_str`. Set
+  `tickers.cik` for each tracked ticker (multi-class share one CIK).
+- From `submissions/CIK.json`: `sic`, `sicDescription`, `fiscalYearEnd` →
+  `tickers.sic/sic_description` (+ fiscal anchor for YTD/Q4).
+- **Submissions is paginated — full history needs the shards.** `filings.recent`
+  holds only the **latest 1000** filings (verified: Apple `recent` = 1000). Older
+  accessions live in `filings.files[]` = `[{name, filingFrom, filingTo,
+  filingCount}]` (e.g. `CIK0000320193-submissions-001.json`, 1236 filings
+  1994–2015), each a bare object with the **same parallel arrays** including
+  `reportDate`, `acceptanceDateTime`, and `isXBRL`. The full-history backfill must
+  **follow every `filings.files[].name`** to obtain period identity + `accepted_at`
+  + `isXBRL` for pre-1000 accessions. Incremental runs only need `recent`.
+- Refreshed by the SEC job; a newly added ticker self-resolves on its next run
+  (the CIK fingerprint in the revision forces that run) — until then its snapshots
+  are absent → metrics null, per the plan.
+
+## SourceImporter mapping (source = `sec_facts`)
+
+- `detect_revision` → latest daily-index date (or `backfill` sentinel on first run).
+- `stage` → resolve tracked CIKs; (incremental) parse indices since last date →
+  tracked filers → fetch their companyfacts → build per-accession snapshot rows;
+  (backfill) fetch all tracked companyfacts. In-memory staged set (KISS, per A1).
+- `validate` (fail-closed) → tracked-universe **coverage floor** (issuers with ≥1
+  snapshot); **unit/period sanity** (YTD spans within tolerance; EPS in USD/shares);
+  **no duplicate accession**; **filings skipped for missing period identity are
+  counted in `validation_json`** (carry-forward from A1 review); an unexpected
+  companyfacts shape (missing `facts`/`units`) stops promotion.
+- **Index↔Company-Facts consistency gate (the daily index and Company Facts are
+  separate SEC products that can lag each other):** for every tracked index
+  accession marked `isXBRL`, confirm that accession actually appears in the fetched
+  companyfacts before promotion. If any is missing → **fail the run and retry
+  later** — do **not** advance the revision and do **not** record an
+  incomplete/null snapshot for it. Non-XBRL amendments are skipped with a recorded
+  reason in `validation_json`. (The framework only stores the revision on a
+  promoted run, so a failed consistency check naturally leaves the revision behind
+  for retry.)
+- `promote` → **insert** snapshot rows (`ON CONFLICT (accession) DO NOTHING`;
+  immutable — see Decision 2), stamped `import_run_id`; refresh
+  `tickers.cik/sic/sic_description`. A re-fetch that reconstructs different values
+  for an existing accession is reported as a discrepancy, never a silent mutation.
+  Non-destructive (append-only accessions) — no future-row deletion like earnings.
+
+## SEC fair-access (operational, per the plan's non-negotiable)
+
+Identifying `User-Agent` with contact email on every request; well under 10 req/s
+with spacing; exponential backoff on 429; **403 → alert and stop, never
+retry-loop** — with one carved-out exception: `www.sec.gov/Archives` is served
+from an S3 bucket without a `ListBucket` grant, so an **absent** file 403s with
+S3's `AccessDenied` XML rather than 404 (every weekend/holiday daily index does
+this). That one shape is read as "missing"; a real rejection is the WAF's
+`text/html` "Undeclared Automated Tool" page and still stops the run.
+New config: `sec_user_agent`, `sec_request_spacing_seconds`,
+`sec_max_retries`. Keep only the last ~2 fetched artifacts on disk for debugging
+(reproducibility is the normalized Postgres rows, per the plan).
+
+## Explicitly out of scope for A3
+
+- `fundamental_data` cutover (A5 parity gate) — snapshots only in A3.
+- The read-time derivation, API object, and panel (A4).
+- Comparative-only restatements (Decision 2).
+- Point-in-time backtest enforcement (`accepted_at` stored, not yet enforced).
+
+## Decisions (signed off 2026-07-22)
+
+1. **Fetch** — EDGAR daily-index driven (Decision 1). Approved deviation from the
+   plan's bulk zip.
+2. **Snapshot mapping** — primary-period-only per accession; comparative-only
+   restatements out of scope (Decision 2). Approved.
+3. **Backfill depth** — seed **full** available history per issuer on first run
+   (cheap to store; powers the quarter tape / multi-year YoY). Approved.

+# Fundamentals production deployment
+
+This is the one-time production setup for the Dolt earnings and SEC fundamentals
+imports. The A5 scoring cutover was approved on 2026-07-24; the compat-cache write
+path is still default-off until the explicit production switch below is set. Do
+not add OS cron entries: the application scheduler owns both jobs.
+
+## What the deployment adds
+
+- `Dolt Earnings Import (shadow)` runs daily at 02:30 America/New_York.
+- `SEC Fundamentals Import` runs daily at 04:00 America/New_York. Its local
+  `fundamental_data` refresh runs only when the A5 switch is enabled.
+- `Fundamentals Parity Report (read-only)` runs daily at 05:30 America/New_York.
+- Both jobs are visible, toggleable, and manually triggerable in Admin → Jobs.
+- Cron expressions are editable in Admin → Schedule.
+- Every attempt is recorded in `data_import_runs`; failures also create a system
+  event. A failed validation does not promote partial data.
+- An SEC filing still missing after the short publication-lag window enters
+  `sec_filing_gaps`. The daily importer retries it automatically; affected
+  tickers are excluded from actionable setups until a snapshot is recovered or
+  a later valid 10-K/10-Q supersedes the gap. Migration `028` materializes older
+  promoted gaps into this queue once, so setup reads never scan import history.
+
+The systemd service uses one application worker. The import framework also holds
+a PostgreSQL advisory lock per source, so an overlapping manual/scheduled run is
+skipped safely.

+```
+
+Use a real monitored contact address. Keep at least 5 GB free at the Dolt data
+path; 8–10 GB gives comfortable growth headroom. The data directory must stay
+outside `/opt/signalplatform`, because deployments use `rsync --delete` there.
+The parity-report directory is also persistent and owned by the service user;
+its small timestamped JSON/CSV bundles form the temporary A5 review trail.
+
+## One-time provisioning
+
+First deploy the commit containing this bundle to production. Then SSH to the
+server and run:
+
+```bash
+cd /opt/signalplatform
+sudo bash ./deploy/provision_fundamentals.sh
+sudo -u deploy bash ./deploy/provision_fundamentals.sh --check
+sudo systemctl restart signalplatform.service
+curl -fsS http://127.0.0.1:8998/api/v1/health
+```
+
+The provisioner is idempotent. It installs the pinned Dolt version, creates the
+persistent directory as `deploy:deploy`, clones
+`post-no-preference/earnings`, configures a repository-local author identity for
+`dolt pull`, verifies free space and `.env`, and refuses an unexpected
+Dolt version. It does not modify PostgreSQL or start an import. The public clone
+does not require `dolt login`.
+
+For a server provisioned before the author-identity check was added, repair the
+existing clone once with:
+
+```bash
+sudo -u deploy -H /usr/local/bin/dolt config --global --add user.name "Signal Platform"
+sudo -u deploy -H /usr/local/bin/dolt config --global --add user.email "signal-platform@localhost"
+```
+
+Do not replace the pinned version with `latest`. A future Dolt upgrade should be
+a reviewed change to `DOLT_VERSION`, followed by the same provision/check flow.
+
+## First-run verification
+
+In Admin → Jobs, wait until no other job is running, then:
+
+1. Trigger **Dolt Earnings Import (shadow)**. Expect `completed` with import
+   status `promoted`; a repeat without an upstream change should report `no_op`.
+2. Trigger **SEC Fundamentals Import**. The first run performs the
+   tracked-universe history backfill and can take materially longer than a daily
+   incremental run. Expect `completed` with import status `promoted`.
+3. Check Admin → System Events. There should be no new import error.
+4. Confirm the next-run times correspond to 02:30 and 04:00 New York time.
+5. Open several ticker pages and confirm the fundamentals panel has populated
+   data and still handles partial/missing issuers cleanly. A ticker held by the
+   quality gate should show **New setups paused** with the specific SEC reason.
+
+## A5 parity observation window
+
+After both shadow imports are healthy, trigger **Fundamentals Parity Report
+(read-only)** once in Admin → Jobs. The **A5 Fundamentals Parity** card above
+the jobs shows the latest coverage/delta summary and provides authenticated JSON
+and CSV downloads. The canonical server-side bundles are archived at:
+
+```text
+/var/lib/signal-platform/reports/fundamentals-parity/
+```
+
+The scheduler then generates one report daily at 05:30 New York time, after the
+02:30 Dolt and 04:00 SEC jobs. Review 5–7 consecutive reports before making the
+cutover decision. A report never writes `fundamental_data`, dimension/composite
+scores, rankings, qualification state, or an approval flag. Materiality bands
+only highlight rows for review; A5 still requires explicit approval.
+
+Each bundle contains legacy and candidate P/E, revenue growth, and earnings
+surprise; definition notes; source revisions and price dates; recomputed legacy
+and candidate fundamental scores; and per-universe fundamental-rank changes.
+Definition changes remain explicit even when numeric deltas are small.
+
+Optional database verification:
+
+```sql
+SELECT source, status, revision, source_max_date, started_at, completed_at,
+       validation_json
+FROM data_import_runs
+WHERE source IN ('dolt_earnings', 'sec_facts')
+ORDER BY id DESC
+LIMIT 10;
+
+SELECT count(*) FROM earnings_events WHERE source = 'dolt_earnings';
+SELECT count(*), count(DISTINCT cik) FROM fundamental_snapshots;
+```
+
+During the longer first SEC run, execute the following in a second SSH session.
+It opens an independent database connection and attempts the same source lock:
+
+```bash
+cd /opt/signalplatform
+sudo -u deploy .venv/bin/python - <<'PY'
+import asyncio
+
+from sqlalchemy import text
+
+from app.database import engine
+from app.services.data_import import _advisory_key
+
+
+async def main():
+    key = _advisory_key("sec_facts")
+    async with engine.connect() as connection:
+        acquired = await connection.scalar(
+            text("SELECT pg_try_advisory_lock(:key)"), {"key": key}
+        )
+        print("UNEXPECTED: lock acquired" if acquired else "OK: source lock is busy")
+        if acquired:
+            await connection.execute(
+                text("SELECT pg_advisory_unlock(:key)"), {"key": key}
+            )
+
+
+asyncio.run(main())
+PY
+```
+
+Expect `OK: source lock is busy`. This is the remaining live-PostgreSQL
+mutual-exclusion check; SQLite unit tests cannot exercise PostgreSQL advisory
+locks. A second Admin trigger should independently report the job as busy.
+
+## A5 production activation (approved 2026-07-24)
+
+The write path is controlled by the SystemSetting
+`fundamental_data_sec_dolt_cutover_enabled`. An absent value, `false`, or any
+value other than `true` leaves `fundamental_data` untouched. Before enabling it,
+confirm the normal PostgreSQL backup containing `fundamental_data` is current.
+
+In **Admin → Settings → Fundamentals data source**:
+
+1. Turn on **Use SEC + Dolt for scoring inputs** and accept the confirmation.
+2. Click **Run refresh now**. The SEC import may be `promoted` or `no_op`; either
+   result runs the local cache refresh.
+
+The weekly legacy collector is automatically skipped while the switch is on, so
+it cannot overwrite the activated cache. The switch remains visible even before
+its SystemSetting row exists because the safe default is off.
+
+If the Admin UI is unavailable, enable the cutover directly in PostgreSQL:
+
+```sql
+INSERT INTO system_settings (key, value, updated_at)
+VALUES ('fundamental_data_sec_dolt_cutover_enabled', 'true', now())
+ON CONFLICT (key) DO UPDATE
+SET value = EXCLUDED.value, updated_at = now();
+```
+
+Then trigger **SEC Fundamentals Import** once in Admin → Jobs. Once enabled, the
+same refresh also runs after an SEC network/validation failure or a source-lock
+skip, because it reads only PostgreSQL snapshots, earnings events, and closes.
+The job message appends the cache row count and changed score-input count when
+the import itself completed successfully.
+
+Verify the switch and refreshed rows:
+
+```sql
+SELECT key, value, updated_at
+FROM system_settings
+WHERE key = 'fundamental_data_sec_dolt_cutover_enabled';
+
+SELECT count(*) AS rows,
+       max(fetched_at) AS refreshed_at,
+       count(pe_ratio) AS pe_available,
+       count(revenue_growth) AS growth_available,
+       count(earnings_surprise) AS surprise_available,
+       count(next_earnings_date) AS next_date_available
+FROM fundamental_data;
+
+SELECT dimension, is_stale, count(*)
+FROM dimension_scores
+WHERE dimension = 'fundamental'
+GROUP BY dimension, is_stale;
+
+SELECT is_stale, count(*)
+FROM composite_scores
+GROUP BY is_stale;
+```
+
+The first refresh intentionally marks affected fundamental and composite score
+caches stale. The normal 15:30 near-close scanner recomputes them before using
+the rankings; until then, reads truthfully expose the stale state. Observe at
+least several scheduled cycles before A6 removes the legacy providers.
+
+## Failure and rollback
+
+- To stop the A5 cache writes without stopping SEC snapshot ingestion, turn off
+  **Use SEC + Dolt for scoring inputs** in Admin → Settings. If the UI is
+  unavailable, set `fundamental_data_sec_dolt_cutover_enabled` back to `false`
+  with the SQL above (changing only the value). This prevents the next local
+  refresh but does not restore rows already replaced. Restore `fundamental_data`
+  from the pre-cutover database backup, or—before A6—manually run the legacy
+  Fundamental Collector if its provider keys and quota are still available.
+- Disable a failing source-import job in Admin → Jobs only when ingestion itself
+  must stop. Existing promoted snapshots/events remain available.
+- Inspect the job runtime, latest `data_import_runs.validation_json`, service
+  logs, and Admin → System Events before retrying.
+- `unresolved_filing` is emitted once when a filing enters automatic retry. It
+  does not require a server command. If the gap is still current after 14 days,
+  `filing_gap_aged` is emitted once with the CIK, accession, and parser/mapping
+  reason. A later valid 10-K/10-Q retires the gap even when the original SEC
+  accession never becomes usable.
+- Successful co-registrant recovery is logged without a warning. New registrants
+  with no XBRL history are also logged quietly, but their ticker page explains
+  that setups remain paused and that successor shells may need `sec_cik_overrides`.
+- Re-run `sudo -u deploy bash ./deploy/provision_fundamentals.sh --check` for
+  binary, clone, permission, disk, or environment failures.
+- The Dolt clone is a reproducible cache and does not need a bespoke backup.
+  PostgreSQL (including `earnings_events`, `fundamental_snapshots`, and import
+  audit rows) must remain covered by the normal production database backup.
+- Do not proceed to A6 until the activated cache has completed the observation
+  window and the forward earnings calendar remains timely.
+- If report generation fails, inspect Admin → System Events and verify
+  `FUNDAMENTALS_PARITY_REPORT_DIR` exists and is writable by `deploy`. Existing
+  reports and all live data remain untouched.

+# Research log — what we tested, what happened, what we kept
+
+Every strategy question we've put to the backtest, in one table. The point is to
+stop re-litigating settled questions: **if a row says "rejected", the experiment
+was run and the data said no.** Detail lives in the linked docs and in
+`reports/*.json` (all committed).
+
+**The one-line summary of the whole platform:** it is a **long-only
+cross-sectional momentum book** — buy the top quintile by beta-adjusted 12-1
+momentum, tilt toward higher volatility, hold ≤ 10 names, cut at 1.5× ATR, then
+trail at 3× ATR for up to 30 trading days. After an initial stop, require the
+daily production gate to fail and subsequently qualify again before re-entry.
+Everything else in the app (composite
+score, Structural S/R, the Gate Target Ladder, sentiment, fundamentals) is
+**display or screening**, not edge.

+
+## 1. What survived — the production strategy
+
+| Component | Status | Why it's there |
+|---|---|---|
+| **Residual 12-1 momentum, top 20%, long-only** | **The edge.** Everything else is scaffolding | Only component with a measured cross-sectional IC. Promoted July 2026 |
+| 80/20 residual-momentum / 6m-volatility rank | Ranking tilt | Buys ~2pp CAGR over momentum-only; costs ~6pp drawdown |
+| 1.5× ATR initial stop | Real exit | Cuts losers fast |
+| 3× ATR trailing stop, 30-day max hold | Real exit | Best Sharpe of every exit tested |
+| Post-stop normal gate reset | Re-entry policy | Stop always closes; a later gate failure and subsequent fresh qualification define the next signal episode. The selected study arm reached Sharpe 1.77 / CAGR 48.3% at capacity 10; live scan-before-outcome timing is stricter (Sharpe 1.68 / CAGR 44.8% analogue). [Full study](post-stop-reentry.md) |
+| Max 10 concurrent positions, 1% risk per trade | Sizing | The cap binds by signal count, but the focused bracket found negligible opportunity cost: cap 15 admitted every blocked setup and added only 0.0018 R/trade in affected paths. [Findings](portfolio-capacity-bracket-findings.md) |
+| Structural S/R | Human-facing product context | Clean, capped zones for charts and alerts; not read by the scanner |

+| # | Experiment | Result | Decision | Evidence |
+|---|---|---|---|---|
+| 1 | **Gate target as a take-profit** (exit at the target, with or without the trail) | Sharpe **2.04 → 1.47**, CAGR halved (50.4% → 28.9%).

+| 3 | **Blanket S/R fallback** (any missing target, not just clear air) | Sharpe 1.82, per-setup expectancy 0.583 → 0.280 R | **Rejected.** 65% of what it admitted were ATR/R:R filter misses, which are actively bad | [sr-levels-and-exits.md](sr-levels-and-exits.md) |
+| 4 | **Expected-value gate** (`min_expected_value` replacing the R:R + probability pair) | Structurally favoured distant lottery targets; selected *worse*-than-random setups | **Removed June 2026.** Settings dropped in migration 020 | migration 009, 020 |
+| 5 | **Blue-sky projected targets** (invent a target above when none exists) | Dilutive under the ATR-trail exit | **Reverted July 2026.** Same root cause as #2 — better targets can't help when the exit ignores them | — |
+| 6 | **SPY 200d-MA regime overlay** (block entries / go flat) | Halves return (315% → 138%), zero drawdown benefit | **Rejected.** The ATR trail already manages downside; the filter blocks the recovery entries that make the money | `backtest-20260708-regime-overlay.json` |
+| 7 | **Short setups** | Fight the trend, drag expectancy | **Excluded** while the momentum gate is active | — |
+| 8 | **Standalone volatility ranking** (high-vol 80, no momentum) | CAGR 31.6%, DD −34.8%, Sharpe 1.12 | **Rejected.** Vol is a *tilt*, not a signal | prod-baseline |
+| 9 | **Low-volatility ranking** | CAGR 2.7%, Sharpe 0.29 | **Rejected.** No edge | prod-baseline |
+| 10 | **Inverse-vol position sizing** | The apparent "win" was **mis-attributed**: the 20% notional cap bound on 95% of entries, so it measured concentration, not vol-sizing. Genuine inverse-vol cuts DD to −18.2% but costs ~58pp return at flat Sharpe | **Rejected** as edge; it's a risk-preference trade | `backtest-20260709-position-sizing*.json` |
+| 11 | **FIP path-smoothness** as tie-breaker/filter | Non-monotonic within the qualified set; thinning the entry stream costs more compounding than the tilt returns | **Rejected as a filter** — but see §4, it's the strongest raw signal we've measured | — |

+## 3. Tuned and confirmed — don't retest on this snapshot
+
+A systematic single-variable sweep (July 2026) confirmed **every** production
+setting. Re-running these against the same ~4-year snapshot is wasted compute and
+invites overfitting.
+
+| Knob | Verdict |
+|---|---|
+| ATR trail multiple {1.5–4.0} | **Keep 3.0** — ≤2.0 whipsaws out the right tail; ≥2.5 is a plateau |
+| Momentum lookback (6-1, 3-1, 12-7 Novy-Marx, composites) | **Keep residual 12-1** — the others have IC ≈ 0 or weaker t-stats |
+| Selection cutoff {70…90} × book size {10, 15, 20} | **Keep 80 × 10** — the focused daily bracket found no meaningful gain from cap 15, while weekly rank replacement hurt. [Findings](portfolio-capacity-bracket-findings.md) |
+| Position sizing (equal-weight, inverse-vol, risk-% sweep) | **Keep 1% fixed-fractional** |
+| Primary-target probability floor | **Keep 20%** — pruned lottery targets, 1,428 → 1,089 qualified, lifted Sharpe |
+| Primary-target R:R selector | **Keep 1.5** — target choice is intentionally independent of the later 2.0 activation floor |
+| Exit policy (hold / SMA50 / 20-day low / technical-40 / ATR trail) | **Keep 3× ATR trail** — best Sharpe (2.04) |
+| **Activation R:R floor `min_rr`** (swept 2026-07-12) | **Keep 2.0** — best in-sample *and* out-of-sample. But it is a **spike, not a plateau** — see below |
+| Post-stop re-entry (nine daily policy arms) | **Keep normal gate reset at production capacity 10** — Sharpe 1.77 vs 1.67 immediate and 1.47 fixed cooldown 5. The result changes with book capacity; see [post-stop-reentry.md](post-stop-reentry.md) |
+
+### The `min_rr` sweep (2026-07-12)
+
+`min_rr = 2.0` had been hand-set in Admin and **never swept** — the gate ablation only
+tested the floor *on vs off*, never its level. Swept against portfolio Sharpe under the
+real exit, with a parity self-check (`reproduces_production_gate: true` — the row at 2.0
+rebuilds production's exact 1,089-setup qualified set).
+
+Reports: `backtest-20260712-min-rr-sweep.json` (in-sample), `-oos.json` (test window only).
+
+| min_rr | qualified | In-sample Sharpe / CAGR | **OOS** Sharpe / CAGR (entries ≥ 2024-07) |
+|---|---|---|---|
+| 0.0 (floor off) | 6636 | 1.98 / 58.5% | 2.02 / 66.2% |
+| 1.2 (old code default) | 3897 | 1.34 / 33.9% | 1.12 / 28.8% |
+| 1.5 | 3127 | 1.20 / 29.6% | 1.12 / 28.8% |
+| 1.75 | 1974 | 1.64 / 44.5% | 1.15 / 27.4% |
+| **2.0 (live)** | 1089 | **2.04 / 50.4%** | **2.78 / 73.3%** |
+| 2.25 | 577 | 1.64 / 31.8% | 1.71 / 31.9% |
+| 2.5 | 286 | 1.67 / 29.0% | 0.68 / 8.7% |
+| 3.0 | 89 | 1.09 / 9.1% | 0.87 / 5.0% |
+
+**Verdict: keep 2.0.** It is the optimum in **both** windows, and the peak reproducing in
+data it was never fitted to is real evidence — the one thing the clear-air experiment
+couldn't show.
+
+**But treat it as fragile, and do not nudge it.** Unlike the ATR trail (a plateau above
+2.5), this is a **spike with a trough beside it**: ±0.25 costs ~0.4 Sharpe in-sample and
+~1.6 Sharpe out-of-sample. A knob that sharp is not a robustly identified parameter, and
+the curve is *bimodal* (floor-off is good, 1.2–1.75 is bad, 2.0 is good) — which is not
+how a well-behaved threshold behaves. We got lucky: the hand-set value landed on the peak.
+
+**Also worth knowing:** turning the floor **off entirely** is the second-best row in both
+windows — nearly the same Sharpe with **substantially higher CAGR** (58.5% / 66.2%) and
+more trades. If CAGR ever matters more than Sharpe here, "no R:R floor" is a live option,
+and it would also sever the last dependency the *gate* has on the weak S/R detector.

+---
+
+## 6. Method rules learned the hard way
+
+1. **Nested lookback windows are NOT out-of-sample.** The clear-air result (#2) was
+   clean, large, and consistent across five nested windows — and still died on a
+   proper train/test split by entry date. Use `BACKTEST_HOLDOUT_SPLIT` / a named
+   validation window — and do not pretend a repeatedly opened window is pristine.
+2. **Check what population an ablation actually admits.** The blanket fallback (#3)
+   looked like it tested the "resistance famine" hypothesis. It didn't — 65% of the
+   setups it let in were a different population entirely, and they drove the result.
+3. **A rising win rate is a warning, not a win.** Both #1 and #12 raised the hit
+   rate while destroying returns. In a right-tailed strategy, "winning more often"
+   usually means you clipped the winners.
+4. **The iron rule:** a signal earns its way into selection *only* through the
+   factor harness — |mean IC| ≳ 0.03, consistent sign, `reliable: true` (≥ 12
+   non-overlapping windows). Never let an unvalidated score gate setups.
+5. **Momentum filters are guilty of tail-trimming until proven otherwise.**
+   Independent failures: take-profit exits, FIP as an in-book filter, gap-up entry
+   caps. Cosmetic quality up, P&L down — the right tail *is* the edge.
+6. **Fill timing is part of the strategy.** Close-fill reports are not deployable
+   numbers for an overnight scanner. Grade promotion under the fill mode you will
+   actually trade.
+7. **Incomplete research artifacts are not results.** The Phase B +0.0575 / t +5.12
+   liquid-fip row was orphaned within hours: it raced a partially built
+   `research.sqlite`. Extender now writes a completion manifest; breadth mode
+   refuses without a match. Same class of protection as calendar-truncation
+   asserts — do not re-mythologize numbers computed on half a universe.
+
+---
+
+## 7. Why we stay with the current strategy
+
+Everything we've tried to add has either failed the backtest, failed
+out-of-sample, or turned out to be measuring something other than what it claimed.
+What's left is a boring, well-documented result: **cross-sectional momentum works;
+the machinery around it mostly doesn't.**
+
+Structural S/R, the composite score, sentiment and fundamentals remain useful
+human context but have no measured edge. The Gate Target Ladder is different:
+it is internal screening machinery whose broad historical-price-traffic behavior
+was preserved explicitly and volume-free, with exact full-period parity. It is
+still neither market structure nor an exit. The one component that *does* have
+measured predictive edge is the momentum gate, and every knob on it has been
+swept and confirmed. After an initial-stop exit, that same gate now also defines
+when a new episode may begin: one later failed observation followed by a fresh
+qualification. The [daily re-entry matrix](post-stop-reentry.md) supports this
+for the current 10-position book, but not as a universal rule for other
+portfolio capacities.
+
+Capacity is now closed as a negative result. The current daily Phase A control
+does reject 519 qualified entries because the ten-slot book is full versus 472
+admitted trades, so the older weekly “cap never binds” claim was stale. But the
+clean cap-15 arm admitted every opportunity the strategy requested and added
+only 0.0018 R/trade in paths where cap 10 bound. Weekly current-rank replacement
+reduced mean EV and created substantial churn. Keep cap 10 and do not build the
+replacement policy. See the [frozen specification](portfolio-capacity-bracket.md)
+and the separate [capacity findings](portfolio-capacity-bracket-findings.md).
+The only open follow-up from that run is the
+[frozen confound-free 0.5% minimum effective-risk-floor A/B](effective-risk-floor-ab.md).
+
+The next real evidence is **forward**, not backward: the live paper-trade record.

+# Earnings gap diagnostic + SUE / PEAD (Tier-1 alpha research)
+
+**Status:** **CLOSED — SUE DEAD**.
+**Branch:** `research/earnings-gap-and-sue`
+**Production impact:** none. Local research only; no earnings filter or SUE integration is shipped.
+
+---
+
+## Pre-registration (locked before the final research run)
+
+### Data
+
+- Historical earnings announcements for the production universe, stored in the
+  real `earnings_events` table and deduplicated on symbol + announcement date.
+- The originally requested 2016 start is amended, with user approval, to the
+  public source's announcement coverage start of 2020-01-22. Earlier EPS-period
+  history may scale later surprises but may never activate a live signal.
+- Report coverage, pairing, duplicates/restatements, annual-rate sanity, and
+  announcement-session quality before either experiment.
+- Point-in-time: an earnings surprise is usable only from announcement date +1
+  trading day. Same-day use is forbidden.
+
+### Experiment 2a — earnings-gap risk (defense, report-only)
+
+Run the production-config book on the approximately 505-name production
+universe with close fills and 0.001 transaction cost per side. Join simulated
+trades to earnings by symbol and date.
+
+1. Among closed trades with realized net R ≤ -1.0, report the fraction with an
+   announcement strictly after entry and before exit, alongside the base rate
+   for all trades.
+2. Compare entries within three trading sessions before an announcement with
+   all other entries: count, mean/median R, win rate, p05, and p95.
+3. Compare stops within one trading session after an announcement with all
+   other stops and exits.
+
+Verdict is always `INFORMATIONAL`. Report only: no filter arm, recommendation,
+or implementation. The right tail must be shown alongside the left tail.
+
+### Experiment 2b — SUE / PEAD (offense)
+
+Signal `sue_latest`:
+
+\[
+\text{SUE} = \frac{\text{actual} - \text{estimate}}
+{\sigma(\text{trailing 8 surprises})}
+\]
+
+Use at least four trailing surprises; if estimate history fails the registered
+quality gate, use `(actual - estimate) / price` and name that fallback. Activate
+at announcement date +1 trading day, carry for 63 trading days, then drop the
+symbol from the cross-section.
+
+Evaluate mean weekly Spearman IC on the existing non-overlapping-window harness.
+Always report `sue_latest`, `mom_12_1`, and `mom_12_1_resid` on identical
+week-symbol-forward-return cells, plus SUE inside the top momentum quintile.
+
+### Mechanical verdict rule
+
+- **PASS** only if unconditional `sue_latest` has mean IC ≥ +0.03,
+  `reliable: true` (at least 12 windows), and positive signs in both the pre-2021
+  and post-2021 eras.
+- **FAIL** otherwise, with terminal verdict `SUE DEAD for this stack`.
+- PASS stops at `SUE PASS→PENDING_HUMAN`; integration design remains a separate
+  human decision. FAIL is terminal and no variants are proposed.

+# Effective initial-risk floor A/B - frozen specification
+
+Date frozen: 2026-08-05
+Branch: research/portfolio-capacity-rebalancing
+Runner: scripts/run_portfolio_construction_matrix.py
+Study ID: risk-floor-ab
+
+## Question
+
+Does rejecting an otherwise qualified cap-10 entry when its actual initial
+stop-risk after cash and notional sizing is below 0.5% of marked equity improve
+trade selection?
+
+The completed capacity bracket cannot answer this. Its cash_unbounded arm
+removed the count cap and applied the 0.5% floor simultaneously. In the 70 paths
+where the control cap never bound, that arm still raised mean EV from 0.328 to
+0.399 R and profit factor from 1.60 to 1.75 while trades fell about 8% and
+exposure stayed nearly flat. Capacity was a no-op in those paths, so the floor
+is the plausible cause, but the prior arm remains confounded.
+
+This A/B changes only the floor. It has no formal promotion gate and does not
+automatically change production.
+
+## Frozen arms
+
+1. cap10_incumbent: current production-style cap-10 control, with no minimum
+   effective-risk floor.
+2. cap10_min_risk_005: the same cap-10 strategy, rejecting an entry only when
+   actual initial stop-risk after cash/notional sizing is below 0.5% of marked
+   equity.
+
+Both arms have max_positions=10, weekly replacement disabled, 1% target risk
+per trade, and identical admission ordering. The only differing simulator
+argument is min_initial_risk_fraction: None versus 0.005.
+
+All other settings remain the frozen daily Phase A control: current production
+construction universe, full-universe residual-momentum/low-volatility 80/20
+rank, threshold 80, normal gate-reset re-entry, close fills, 3x ATR trail,
+30-session maximum hold, 20% per-position notional ceiling, no leverage, and
+costs of 0.10% and 0.20% per fill.
+
+Every priced symbol contributes to the daily cross-sectional rank. Rank-only
+symbols cannot submit trades. Validation retains the 450-600-symbol production
+construction guardrail and the legacy-snapshot column-scoped loader.
+
+## Frozen cohorts
+
+Reuse the completed bracket's point-in-time daily candidate/rank cache and
+cohort manifest:
+
+- Empty book: first eligible session of each month in 2019-2025, with 504 prior
+  scoring sessions and 252 measurement sessions. This is the primary start-date
+  evidence.
+- Warm book: weekly seeds 63-126 sessions before each 2019-2025 annual anchor,
+  with state carried into the same 252-session measurement window. This is a
+  state-carrying replication, not independent evidence.
+
+The expected realization is 78 empty-book paths, 97 warm paths, seven annual
+clusters in each protocol, two costs, two arms, and 700 cells.
+
+Do not use warm-seed IQR as evidence. Six of seven completed-bracket anchors
+were structurally degenerate because fractional sizing is scale invariant and
+the 30-session maximum hold washed out books before anchors. The 2023 exception
+shows that state carrying itself works.
+
+## Reporting and interpretation
+
+For every protocol and cost, pair identical paths. Report:
+
+- mean, median, P25, and P75 paired net-EV changes in R;
+- positive-path and bit-identical-path fractions;
+- the median paired delta within each year and the median across seven years;
+- simple 90% cluster-bootstrap context for EV and Calmar, with no CI gate;
+- mean paired PF, Gain-to-Pain, Sortino, Calmar/MAR, CAGR, maximum drawdown,
+  total return, and Sharpe changes;
+- trades, floor rejections, holding time, cash, gross exposure, average/peak
+  positions, turnover, and costs.
+
+Means and identical-path fractions must appear beside medians so inert cohorts
+cannot turn a left- or right-skewed treatment into a misleading zero headline.
+For these 252-session windows, the implementation's full-window Calmar is CAGR
+divided by maximum drawdown, the same numeric definition commonly called MAR;
+do not present the duplicate label as a second independent metric.
+
+Today's production membership is projected backward. Use paired differences
+for the treatment conclusion; absolute profitability remains descriptive and
+survivorship-biased. Empty and warm protocols cover the same seven market years
+and must not be interpreted as independent replications.
+
+Interpretation is deliberately simple:
+
+- a positive result means the isolated floor improves the paired EV
+  distribution without an economically important loss of total-return or
+  drawdown quality;
+- a negative result closes the floor;
+- mixed EV/portfolio-quality results are reported as a trade-off, not forced
+  through a composite score.
+
+## Reproducibility and macOS execution
+
+The authoritative run refuses a dirty worktree. Its fingerprint includes the
+implementation commit, this specification hash, snapshot hash, candidate-cache
+key, construction view, cohort manifest, arm definitions, costs, and study
+version. Cells checkpoint atomically and --resume verifies the fingerprint.
+
+From the repository root on macOS:
+

+    ./.venv/bin/python -m pip install -e '.[dev]'
+
+Preflight, reusing the completed bracket's candidate/rank cache:

+
+On an M2 Pro, eight workers is the explicit high-utilization setting. Use six
+instead on a memory-constrained machine; auto intentionally caps itself at six.

+# Execution recovery (2026-07-18) — when you fill is the edge you leave on the table
+
+Report: `reports/execution_recovery_matrix.json` / `.md`  
+Follows Phase A A4 ([phase-a-matrix.md](phase-a-matrix.md)).  
+Arms: `close_control` · `next_open` · `stale_close` · `next_open_gap2`.
+
+Mechanics verified before sign-off: `stale_close` re-anchors stop to
+fill − 1.5×ATR(signal day); no same-day stop after a close fill; each t−1
+candidate keeps its own gate/rank cross-section (no lookahead). Numbers trusted.
+
+---
+
+## Results
+
+| Arm | Full Sharpe | Full CAGR | Full DD | Train Sharpe | Val Sharpe |
+|---|---:|---:|---:|---:|---:|
+| **close_control** | **1.77** | **48.3%** | **21.6%** | 1.75 | 1.68 |
+| **stale_close** | **1.57** | **40.6%** | **21.8%** | 1.36 | **1.74** |
+| next_open | 1.20 | 30.0% | 28.2% | 0.94 | 1.44 |
+| next_open_gap2 | 1.06 | 25.2% | 27.8% | 0.72 | 1.41 |
+
+### Monotonicity (the strongest evidence)
+
+In every window, Sharpe recovers as the fill moves **toward** the signal:
+
+| Window | next_open → stale_close → close |
+|---|---|
+| Train | 0.94 → 1.36 → 1.75 |
+| Validation | 1.44 → 1.74 → 1.68* |
+| Full | 1.20 → 1.57 → 1.77 |
+
+\*Val close 1.68 is within SE of stale 1.74 — not a break of the story.
+
+A dead edge does **not** produce a monotone gradient in fill timing. A live edge
+that is progressively surrendered to execution delay does. Combined with full-period
+**DD recovery** (28.2% → 21.8% ≈ close’s 21.6%), this confirms the diagnosis:
+**when you fill**, not decaying alpha.
+
+### Auto-flag `recover: False` is not a null
+
+Pre-registered recovery applied the “≥ close − 0.5 SE” bar to **`stale_close`**,
+the **lower-bound** arm (one full session of lag). Flags:
+
+| Flag | Result |
+|---|---|
+| near_close_control (val) | **True** (Δ +0.06) |
+| beats_next_open | **True** (val Δ +0.30) |
+| train_ok | **False** (1.36 vs need ≥ ~1.39 — miss by ~0.03) |
+
+The floor missed “≥ close − 0.5 SE” by 0.03 while the live design is expected to
+sit **above** the floor. The flag worked correctly on the wrong object.
+
+**Log sentence:** *Partial recovery proven; full recovery needs same-day fill.*
+
+### Live outcome bracket
+
+| Bound | Arm | Meaning |
+|---|---|---|
+| Floor | stale_close ~1.57 full | One-session-stale close fill (conservative) |
+| Ceiling | close_control ~1.77 full | Same-day close; optimistic only by final ~15 min of signal info |
+
+Real near-close execution (scan ~15:30–15:40 ET on a ~99% complete bar, MOC by
+15:50/15:55) is signal-at-partial-bar filled at the same close the control uses.
+**Live truth is bracketed [1.57, 1.77]** with residual uncertainty of ~15 minutes
+of staleness, not 24 hours — expect near the **top** of the bracket.
+
+`stale_close` alone already justifies the schedule change. **No further fill-timing
+simulation on this snapshot** — the bracket is the result. You cannot simulate
+15:45 partial bars from daily data, and you do not need to.
+
+### Gap-cap — dead (third tail-trim instance)
+
+`next_open_gap2` worse than plain next_open on every window (full Sharpe 1.06 vs
+1.20). **262** full-period gap-ups skipped — they were continuations.
+
+This is the **third independent instance** of the same lesson:
+
+1. Take-profit exits (gate target as TP)  
+2. FIP as an in-book filter  
+3. **Gap-up entry caps**
+
+Any rule that trims the right tail improves cosmetic quality metrics and destroys
+P&L. **Standing method rule:** momentum filters must be presumed guilty of
+tail-trimming until shown otherwise.
+
+---
+
+## Decisions locked
+
+1. **Biggest lever is execution scheduling**, not a strategy rewrite.  
+2. ~~**Until near-close execution is live:** grade strategy promotion under
+   `fill_mode=next_open`; keep close-fill as historical control.~~
+   **Superseded 2026-07-18** — near-close shipped to prod (commits 736451e,
+   a71dd4a; migration 023). Decision baseline is now **`fill_mode=close`**
+   (≈ the live near-close path). Live fill quality is monitored via
+   `fill_mode=near_close` paper trades: entry price vs the day's final close
+   (available after the after-close fetch overwrites the partial bar).  
+3. **After near-close ships:** grade under a close-like / near-close fill mode
+   (actual live path). **← Active.**  
+4. **No more sim arms** on fill timing for this snapshot.  
+5. **Gap-cap:** do not ship.  
+6. **Strategy work** (nasdaq_all, fip_id, sector) waits until the execution path
+   is decided — those experiments must be graded under the fill mode you will trade.
+
+---
+
+## Ops design — implementation plan (code-checked)
+
+Assumptions verified against current code before ship:
+
+- Intraday pipeline already fetches/upserts the **in-progress day-t bar** all
+  session (`fetch_ohlcv` end_date defaults to today). Near-close job =
+  **OHLCV fetch → R:R scan** (no new snapshot synthesizer).
+- One global `schedule_timezone` (default `Europe/Berlin`); stored
+  `SystemSetting` values shadow code defaults — **defaults alone do not
+  migrate prod**.
+- `observe_reentry_gate_transitions` stamps timestamps with **no same-day
+  guard** today — dual scans would accelerate fail→requalify unless fixed in
+  `trade_policy`.
+
+### Semantic guard (ship step 1 — precondition)
+
+In `trade_policy` (not the scheduler):
+
+> `reentry_gate_requalified_at` may only be set when `reentry_gate_failed_at`
+> falls on an **earlier America/New_York trading date** than the current
+> observation.
+
+Manual mid-day scans stay allowed; same-day fail+qualify cannot unlock.
+Unit test: fail 10:00 / qualify 15:35 same day → still locked; qualify next day → unlocked.
+
+### Schedule split
+
+| Slot (America/New_York) | Jobs |
+|---|---|
+| Morning (~02:00) | OHLCV backfill, benchmark, sentiment, fundamentals — **no** qualifying R:R scan |
+| Near-close (~15:30 Mon–Fri) | OHLCV fetch (refresh day-t bar) → **R:R scan** (only daily qualifying observation) |
+| After close (~16:30–17:00) | **Outcome eval** on its own slot (not chained to the partial-bar scan) |
+| Intraday hourly | Unchanged in NY terms; last ~16:00 still mid-session under 15m feed |
+
+- Near-close scan **1–5 only**; US-holiday no-ops are fine (stale identical data
+  can’t flip gates) — comment only, no exchange calendar.
+- **Do not** run morning + near-close qualifying scans; move the scan, don’t add a second.
+
+### Behavior change to document (not an accident)
+
+With scan at ~15:35 ET, stops closed by **earlier same-day** intraday outcome
+evals can get a **same-day fail observation** — closer to the **promoted**
+`gate_reset` arm (stop-day close may establish failure) than today’s
+`strict_gate_reset` analogue (scan always before any eval). Stops after the
+bell still wait a day. Rewrite README “Live timing matters” / post-stop sections
+and a line here when shipping.
+
+### Feed / paper honesty
+
+- Document 15-minute delayed SIP: 15:35 scan may see ~15:20 prices; OK for 12-1.
+- Paper entry price ≈ scan entry (near close) is nearly automatic; add
+  **`fill_mode=near_close` era tag** so Track Record can separate morning-scan /
+  near-close / future broker-routed eras.
+- Morning sentiment staleness is display-only; gate is price-only (GTL parity /
+  neutral-sentiment backtest). One doc line closes that.
+
+### Stored settings migration (ship step 4)
+
+Flip global default TZ to `America/New_York` and re-express crons in NY time.
+**Also** migration (or documented Admin rewrite) of stored `schedule_*` keys so
+prod does not keep 07:00 Berlin silently.
+
+### Ship order
+
+1. `trade_policy` distinct-day requalify guard + unit test  
+2. Near-close job = existing fetch → scan; outcome eval own after-close slot  
+3. Paper `fill_mode=near_close` era tag; verify entry marking  
+4. Defaults + **stored settings migration** + README/research timing rewrite  
+
+### Out of scope
+
+Broker MOC routing, more fill-timing sim, nasdaq_all / fip / sector (grade later
+under the fill mode you trade).

+# Broad-universe fip_id IC research (Phase B)
+
+**Status:** **Parked / closed for now.** Unconditional fip not green; mom-conditional lead logged; breadth-momentum thesis challenged. No book sim until reopen.  
+**Production impact:** none. Display card remains context-only. No deploy from this work.  
+**Artifacts:** research log + compact reports + env-gated harness hooks; tooling stays for a future reopen.
+
+## Scope
+
+- Research only — production universe, gate, scanner, schedule unchanged.
+- Snapshot: `research.sqlite` (~4,650 tickers = prod + nasdaq_all extend).
+- Liquid mask: top **1,500** by point-in-time 63d median $vol, price ≥ **$5**/week.
+- **Completion manifest required:** extender writes `<snapshot>.manifest.json`; breadth runners refuse without a matching complete manifest (see §Race guard).
+
+## Caveats
+
+- Survivorship bias (today’s constituents, history backfilled).
+- IEX volume undercount → relative $vol rank only.
+- Pool skew: Nasdaq-heavy; missing pure NYSE mid-caps.
+- Do not mix multi-signal tables across universe baselines.
+- **Do not cite orphaned 21:14 numbers** (see below).
+
+---
+
+## Fingerprint (505-name prod)
+
+| | Expected | Observed |
+|---|---:|---:|
+| mean IC | −0.045 | **−0.045** |
+| t-stat | −2.9 | **−2.91** |
+| weeks / N / reliable | ≥12 / ~500 / true | 35 / 497.7 / true |
+
+**Pass.** Formula + pipeline trustworthy.
+
+Residual momentum on the same fingerprint (what the production book ranks on): **IC +0.055 / t +1.98**.
+
+---
+
+## The orphan (21:14) — root cause
+
+| Source | fip IC (liquid ~1500) | t |
+|---|---:|---:|
+| Orphan run 21:14 (removed from tree; was `fip-breadth-20260718-211440-breadth.json`) | **+0.0575** | **+5.12** |
+| Single-sourced recompute on complete snapshot (2026-07-19) | **−0.0168** | **−1.85** |
+
+That is a **sign disagreement** on the same intended quantity. Method rule: the number you cannot reconcile is the number you cannot use.
+
+### Verdict: orphaned — raced the snapshot build
+
+**Not** “orphaned, unexplained.” The mechanism is derivable from the table itself:
+
+1. **Code was not the difference.** Reconcile shows the old harness path and the new shared filter produce **identical** results on current data (−0.0168 / −1.85). The implementation fork is closed.
+2. **Data was the difference.** On today’s complete snapshot the liquid mask **binds in 97.1% of weeks** at top-N = 1,500. Dense signals (e.g. `vol_6m`) post-mask at **exactly 1,500**. The orphaned report’s `vol_6m` averaged **~1,475** cross-section — a masked run on complete data cannot do that. At 21:14 the eligible pool was smaller than 1,500 and the mask never bound.
+3. **Timeline fits.** Extender fixes landed ~20:32 / 20:34; full fetch takes ~30 minutes; breadth run fired **21:14** against a partially built `research.sqlite`. Every number in that report was computed on an incomplete universe.
+
+**Do not cite +0.0575 / t +5.12.** It survived less than six hours of contact with project discipline — that is the system working, not time wasted. The orphan JSON was **deleted from the tree** (still in Git history) so it cannot be re-imported as evidence.
+
+**Kept artifacts**
+
+| File | Role |
+|---|---|
+| `reports/fip-reconcile-20260719-000520.json` | Authoritative single-sourced ICs (compact; membership dumps stripped) |
+| `reports/fip-breadth-20260718-211440-fingerprint.json` | Prod fingerprint pass |
+
+### Race guard (same class as calendar truncation)
+
+| Piece | Behavior |
+|---|---|
+| `extend_snapshot_universe.py` | Clears any prior manifest on start; on full completion writes `<output>.manifest.json` with `complete=true`, ticker / OHLCV / rank_only counts, `finished_at`. `--limit` smoke runs write `complete=false`. |
+| `run_fip_breadth_research.py` / `run_fip_breadth_diagnostics.py` | **Refuse** breadth mode unless a matching complete manifest exists and live counts equal the recorded totals. |
+
+Helper: `scripts/research_snapshot_manifest.py`.
+
+---
+
+## Authoritative unconditional liquid fip (post-reconciliation)
+
+| metric | value |
+|---|---:|
+| mean_ic | **−0.0168** |
+| ic_t_stat | **−1.85** |
+| weeks | 35 |
+| avg_cross_section (**post-mask IC sample**) | 1471.2 |
+| avg_raw_pool | 3214.4 |
+| avg_eligible_pre_mask | **2338.4** |
+| mask_binds_pct | **97.1%** |
+| reliable | true |
+
+**Mask binds hard** on complete data (eligible ≫ 1500). Post-mask IC N for fip is ~1471 because not every liquid name has a valid 12-1 fip path — that is signal availability, not a non-binding mask. Contrast orphan `vol_6m` avg N ~1475 vs complete-data `vol_6m` avg N **1500**.
+
+Harness `_signal_evaluation` vs manual IC through the same filter: **exact match** (−0.0168 / −1.85).
+
+**Iron rule unconditional:** **not green** (|IC| 0.017 < 0.03), correct mild-negative sign.
+
+---
+
+## Context table (orphaned 21:14 vs authoritative) — kill the myth numbers
+
+The context table died with the orphan. **−0.16 must not survive in the log.**
+
+| signal (liquid ~1500) | orphaned (21:14) | authoritative (shared filter) | consequence |
+|---|---:|---:|---|
+| **vol_6m** | −0.16 / t **−6.1** | **−0.048 / t −1.36** | “High-vol tilt harmful on breadth” **downgrades from finding to directional hypothesis** — not significant |
+| **raw mom** (`mom_12_1`) | +0.10 / t +4.6 | **+0.046 / t +1.91** | Below iron-rule bar on this pool |
+| **resid mom** (`mom_12_1_resid`) | +0.04 / t +2.3 | **+0.029 / t +1.33** | Ditto, and weaker than raw |
+
+### Breadth-momentum thesis — challenged
+
+That last pair is the sobering one. Momentum on liquid breadth is **marginal**. The “more breadth strengthens the momentum t-stat” thesis that motivated Phase B is **empirically wrong on this pool**: same 35 weeks, triple the names, residual-mom t-stat **fell** versus the 505-name fingerprint (**0.055 / 1.98** → **0.029 / 1.33**). The clean momentum edge lives in the large-cap universe already traded.
+
+Meanwhile the strongest reliable signal on liquid breadth is now **mom-conditional fip** (−0.088 / −4.58) — but a fip tilt presupposes a breadth momentum book worth tilting, and that is no longer free.
+
+---
+
+## Compositional story (supported)
+
+`fip_id = sign(PRET)×(%neg−%pos)` pools:
+
+- **Continuous winners** → want **negative** IC  
+- **Continuous bleeders** → want **positive** IC  
+
+| check | IC | t | read |
+|---|---:|---:|---|
+| Prod-universe subset inside liquid | **−0.044** | **−2.88** | Matches fingerprint → compositional, not regime change |
+| Tier 1–800 (senior) | **−0.035** | **−2.99** | Winner leg |
+| Tier 801–1500 (junior) | **+0.014** | +1.25 | More bleeder / junk weight |
+| Lagged membership (prior-week $vol) | −0.010 | −0.93 | Same sign as same-week; not a +5σ leak artifact |
+
+**Do not log “on Nasdaq, jumpy paths outperform.”** That would mythologize an orphaned +0.06.
+
+---
+
+## Platform-relevant test: momentum-conditional fip
+
+Among liquid top-1500, keep **mom_12_1 ≥ P80** (~294 names/week):
+
+| metric | value |
+|---|---:|
+| mean_ic | **−0.0879** |
+| ic_t_stat | **−4.58** |
+| ic_positive_pct | 22.9% |
+| weeks | 35 |
+| reliable | **true** |
+
+Computed on the **same single-sourced path** as the authoritative −0.017. This is the paper’s claim and the only version a gate could consume.
+
+| Decision | |
+|---|---|
+| Unconditional fip | **Closed** for production |
+| Mom-conditional fip | **Alive as book-tilt candidate only** — and only after a baseline breadth book proves itself |
+| Display card | Stays |
+| Production change | **None** |
+
+---
+
+## Vol-tilt warning (softened)
+
+| signal (liquid, single-sourced) | IC | t |
+|---|---:|---:|
+| vol_6m | −0.048 | **−1.36** |
+| mom_12_1 | +0.046 | +1.91 |
+| mom_12_1_resid | +0.029 | +1.33 |
+
+High-vol names **tend** to underperform on this pool relative to a clean S&P-like book — that is a **directional hypothesis**, not a finding. Production **80/20 high-vol tilt** was validated on S&P-like names. If the universe ever broadens in production, re-validate that tilt; do not treat the orphaned −0.16 / t −6.1 as evidence.
+
+---
+
+## What this means for the book experiment
+
+A fip tilt presupposes a breadth momentum book worth tilting — **that is no longer free.**
+
+**Caution against over-reacting the other way:** modest cross-sectional IC does not preclude a good book. The 505-name book turns resid-mom IC ~0.055 into Sharpe ~2 because the gate trades the **extreme tail**, not the linear sort. The breadth book might still work; it just has to **prove it** before the fip arm means anything. If the baseline cannot clearly beat the existing production book’s territory, fip’s future is a footnote regardless of −4.58.
+
+### Parked next step (if reopened): pre-registered two-arm design
+
+Not started — **design only**, pre-register before any sim:
+
+| Arm | Definition |
+|---|---|
+| **A — baseline** | Top-quintile residual (or raw — pick one and lock) momentum book on liquid-1500; **no fip**; honest costs; next-open or near-close fills; production-like capacity / risk / stops |
+| **B — +fip tilt** | Same book + mom-conditional fip tilt (among mom winners, prefer smoother paths / negative fip_id) |
+
+| Grade on | Spec |
+|---|---|
+| Split | Entry-date train / validation (`BACKTEST_HOLDOUT_SPLIT` naming — not pristine holdout) |
+| Metrics | Sharpe + Mertens/Lo SE, PSR, **DSR**; max DD; turnover; cost drag |
+| Promote bar | Arm A must be in production-book territory first; Arm B must beat A on validation with DSR-aware multiple-testing honesty |
+| Fail-closed | If A fails, fip is a footnote; do not shop tilts on a dead baseline |
+
+---
+
+## How to re-run (research branch only)
+
+```powershell
+# 1) Full extend writes completion manifest (required)
+.\.venv\Scripts\python.exe scripts\extend_snapshot_universe.py `
+  --source backtest_snapshots\prod.sqlite `
+  --output backtest_snapshots\research.sqlite
+
+# 2) Breadth / diagnostics refuse without matching manifest
+.\.venv\Scripts\python.exe scripts\run_fip_breadth_diagnostics.py `
+  --research-snapshot backtest_snapshots\research.sqlite `
+  --prod-snapshot backtest_snapshots\prod.sqlite `
+  --workers 6 --allow-spawn
+```
+
+---
+
+## Bottom line
+
+1. Formal iron-rule screen: **not green** either before or after reconciliation.  
+2. **+0.0575 / +5.12 is orphaned: raced the snapshot build** — authoritative unconditional liquid fip is **−0.017 / −1.9**; mask binds (~97%) on complete data.  
+3. Context-table myths die with the orphan: **vol −0.16 is not real**; authoritative vol is **−0.048 / t −1.36** (directional only).  
+4. Compositional tug-of-war is the right story; jumpiness premium is not.  
+5. **Breadth does not strengthen residual-mom t-stat** on this pool (0.055/1.98 → 0.029/1.33).  
+6. **Mom-conditional −0.088 / −4.6 stands** on the single-sourced path → optional next step is a **pre-registered two-arm breadth book** (baseline first), not a gate wire-in.  
+7. Manifest guard is in place so the race cannot recur silently.

+# Fundamentals ranking-overlay research
+
+Status: completed 2026-07-23. Decision: keep production scoring and qualification unchanged.
+
+## Question
+
+Does using point-in-time SEC fundamentals to reorder already-qualified long setups improve the production portfolio's risk-adjusted return? The experiments changed ranking only; qualification, execution, sizing, capacity, costs, ATR exits, and post-stop re-entry remained unchanged.
+
+## Method
+
+- The control was the production 80/20 residual-momentum / volatility rank.
+- SEC facts became visible only after `accepted_at`, using the newest visible accession per fiscal period.
+- Portfolio simulations used daily entry opportunities, close fills, the production gate-reset re-entry policy, and a 30-session horizon.
+- Train contained entries before 2024-01-01, validation covered 2024, and test began 2025-01-01.
+- Missing composite scores were neutral at 50.
+- Deflated Sharpe used the complete registered arm count for each experiment.
+
+The snapshot contained 511 tracked tickers, 507 unique CIKs, 30,494 SEC snapshot rows, and prices from 2021-06-24 through 2026-07-22.
+
+## Initial experiment
+
+The first registered matrix tested quality, growth, and balanced composites at 10%, 20%, 30%, and 40% weights: 13 trials including control.
+
+No overlay passed the train and validation requirements. The most attractive full-period result, balanced at 10%, failed validation and improved test Sharpe by only 0.06.
+
+Review also found that filing-time diluted EPS and shares are not reliably comparable across stock splits. A snapshot audit found share-count changes above 25% for 90 of 461 issuers with comparable 2021+ periods, including recognizable split ratios for AMZN, GOOG, NVDA, CMG, and GE plus some obvious unit anomalies. Consequently, EPS growth and share-count change cannot be trusted for historical ranking without point-in-time split factors.
+
+The complete initial result is recoverable from Git commit `7f944d7`.
+
+## Split-safe follow-up
+
+The follow-up excluded diluted-EPS growth and share-count change completely. It tested:
+
+- Quality: operating margin, FCF margin, and low net-debt/EBITDA, requiring at least two inputs.
+- Growth: revenue growth only.
+- Balanced: equal quality and growth weights.
+- Overlay weights: 5%, 10%, and 15%.
+
+This produced 10 registered trials including control. Growth coverage among qualified candidates was 88.96%; lack of data was not the limiting factor.
+
+| Window | Control Sharpe | Revenue-growth 5% | Delta |
+|---|---:|---:|---:|
+| Train | 1.26 | 1.31 | +0.05 |
+| Validation | 2.52 | 2.64 | +0.12 |
+| Test | 1.99 | 1.99 | 0.00 |
+| Full | 1.86 | 1.87 | +0.01 |
+
+Revenue growth at 5% mechanically passed the deliberately permissive "not worse" gate, but did not demonstrate an economically meaningful edge:
+
+- Test CAGR rose from 54.4% to 56.1%, while full-period CAGR fell from 52.1% to 51.5%.
+- Full-period trade overlap was 68.53%, so roughly one-third of selections changed for essentially unchanged Sharpe.
+- Revenue-growth IC was 0.0006 in train, 0.0053 in test, and 0.0116 full-period with a full-period t-stat of 0.55.
+- Growth weights of 10% and 15% deteriorated; quality and balanced composites failed.
+- The test window had already been inspected, so this follow-up was sensitivity evidence rather than a fresh out-of-sample result.
+
+The complete split-safe result is recoverable from Git commit `dba7ea7`.
+
+## Decision
+
+- Do not add fundamental weight to production ranking or the automated qualification gate.
+- Do not run another historical weight sweep on the same sample; it would add data-mining rather than new evidence.
+- Keep fundamentals informational and user-facing in the UI.
+- A5 source-parity and cutover work can proceed independently without changing scoring behavior.
+- Treat historical EPS growth and share-count change as non-comparable across corporate actions until a split-aware solution or a conservative UI guard exists.
+
+Revisit automated weighting only with materially better data, such as point-in-time split factors and historical constituent/delisting coverage, followed by genuinely new forward paper evidence.
+
+## Limitations
+
+The snapshot uses today's tracked universe rather than historical membership and delisted securities, creating survivorship bias. Absolute CAGR and Sharpe must not be interpreted as unbiased live expectations. The relative comparison is useful, but the observed test window and short number of independent factor windows limit statistical power.
+
+## Repository cleanup
+
+The experiment-only scorer, runner, Mac launcher, caches, tests, and expanded report bundles were removed after this decision. They remain recoverable from commits `eae4d34`, `34d6dda`, `7f944d7`, and `dba7ea7`. Production fundamentals derivation and ingestion remain unchanged.

+# History-depth extension (Tier-1 alpha research)
+
+**Status:** **CLOSED.** Sector-residual deep test **FAIL** — Task 1 archived as rejected (see supersession).

+**Authoritative sector grade:** `reports/sector-resid-deep-20260719-113319.json`  
+**Production impact:** none. **Do not retune any production knob on deep history.**
+
+---
+
+## Pre-registration (locked before rebuild)
+
+### Motivation
+
+All current conclusions rest on ~35 non-overlapping weekly windows in essentially
+one post-2021 regime. Extending history toward max Alpaca daily-bar depth adds
+the 2018 vol shock and full 2020 crash (where the feed allows).
+
+### Protocol
+
+1. **Empirical coverage first** — bars per calendar year per symbol; document
+   where the feed thins out. Do **not** assume a uniform start date.
+2. **Rebuild the research snapshot completely** from prod source + max history
+   per symbol (`Adjustment.SPLIT`, ~200 req/min pacing via existing extender).
+3. **Race guard (rule 6)** — refuse analysis until completion manifest is
+   `complete=true` and live counts match.
+4. **Re-run full signal harness** (all existing signals incl. sector residual /
+   SUE if present) on the extended window.
+5. **Report per signal:** mean IC, t, window count, and **era split**
+   (pre-/post-2021) — diagnostic only, **not a tuning input**.
+6. **Log prominently:** survivorship bias grows with depth (today’s constituents
+   backfilled). Absolute Sharpe/CAGR on deep history is optimistic; payload is
+   **relative** signal comparisons and IC stability, not levels.
+7. **Do not retune** production knobs. If a knob’s confirmation looks
+   overturned on deep history → report only; human decides.
+
+### Success / interpretation (not promotion of a new signal)
+
+| outcome | meaning |
+|---|---|
+| Sector residual still ≥ market residual on deep IC + stable sign | strengthens Task 1 PROMOTE case |
+| Sector residual collapses pre-2021 | **PARK** Task 1 wire-in |
+| SUE remains weak after full earnings + depth | **DEAD** SUE for this stack |
+| Any production knob looks worse deep | report; no auto-retune |

+
+---
+
+## Critical caveats (must read)
+
+### 1. Sector residual did **not** get a deep-history stress test
+
+`mom_12_1_sector_resid` / `_demeaned` still show **exactly** the Task‑1 short-window
+fingerprint: **35 weeks, N≈498, IC 0.0578, t 2.34**.
+
+On the same run, raw `mom_12_1` has **83 weeks, N≈2278**. So depth worked for
+price-only signals, but sector residual is still limited to the **~505 labeled
+prod names × short factor calendar** (sector map only covers prod; and/or sector
+ETF / two-factor path did not extend usable residual weeks).
+
+**Pre-registered rule:** “Sector residual collapses pre-2021 → PARK Task 1
+wire-in.” Pre-2021 sector residual is **absent** from the era table. That is a
+**PARK**, not a confirmation of the short-window PROMOTE.
+
+Do **not** claim “sector residual beats market residual on deep history” from
+this table — the two rows are **not the same cross-section or window count**.
+
+### 2. `fip_id` sign flips vs production fingerprint
+
+| sample | fip mean IC | t |
+|---|---:|---:|
+| Prod 505, ~5y (fingerprint) | **−0.045** | −2.91 |
+| Research breadth, deep (this run) | **+0.027** | +3.25 |
+
+This does **not** authorize resurrecting unconditional FIP as a book filter. It
+confirms earlier Phase‑B caution: FIP edge is **universe- and sample-dependent**.
+Production display card can stay context-only. Nested lookbacks still not OOS.
+
+### 3. Market residual vs raw momentum on deep breadth
+
+On deep broad IC, **raw 12‑1 (0.066 / t 5.1) ≫ market residual (0.026 / t 2.2)**.
+That does **not** by itself overturn production residual ranking (book A/B was
+on 505 + GTL gate, not pure factor IC), but it is a yellow flag for “residual is
+always the better rank key” stories on broad history. **No auto-retune.**
+
+### 4. Low-vol anomaly is the cleanest deep-history result
+
+`vol_6m` IC −0.12 / t −6.3 full; stronger post-2021. Consistent sign across eras.

+
+## Verdicts (vs pre-registration)
+
+| question | verdict |
+|---|---|
+| Task 1 sector residual wire-in | **PARK** — no pre-2021 sector residual; deep-sample IC not established; short-window PROMOTE stays “human design only,” **not strengthened** by this run |
+| Sector demean | still **DEAD** for promotion (t 1.32, short only) |
+| SUE | **not re-scored here** (no `sue_latest` in harness table) — leave Task 2 **PARK** until full earnings backfill |
+| fip unconditional book filter | remains **rejected / parked** despite sign flip on broad deep sample |
+| Production residual / 80/20 / trail knobs | **no retune** from this report |
+| Overall Task 3 | **COMPLETE as diagnostic** — payload is relative IC + caveats above |
+
+---
+
+## What a human must decide next
+
+1. **Sector residual — decided:** CLOSED / REJECTED (archive complete). No wire-in.
+2. **Do not** retune residual vs raw, FIP, or vol blend from deep IC tables
+   without a pre-registered book A/B on the intended universe.
+3. Optional (separate threads only): finish earnings backfill and re-run SUE;
+   snapshot per-symbol depth guard as tooling.

+
+The table and interpretation from **`history-depth-20260719-103315`** are **UNMASKED, TWO-TIER SNAPSHOT — superseded, directional only, do not cite**. Prod-universe names (and sector residual coverage) were left shallow while breadth names were deepened; sector residual weeks=35 was a data gap.
+
+### Sector-residual deep test outcome: **FAIL** (archived)
+
+**Task 1 CLOSED / REJECTED** — sector residual dead on deep evidence. Archived in
+the research log rejected table (#13). Do not resurrect without a new
+pre-registered protocol.
+
+| check | result |
+|---|---|
+| weeks | **83** (data fix worked) |

+# Phase A research matrix (2026-07-18) — results and decisions
+
+Report: `reports/research-matrix-phase-a.json` / `.md`  
+Branch: `research/portfolio-vol-and-followups`  
+Validation split: entries ≥ **2024-07-01** (called *validation*, not holdout — this window has been opened before).  
+Cadence: daily, production gate/rank/trail + gate-reset re-entry.  
+Pre-registered N for DSR: **20**.
+
+## Pre-registered promotion rule (unchanged after run start)
+
+Promote only if **all** of:
+
+1. Validation Sharpe ≥ control  
+2. Validation max DD not worse by more than **2pp**  
+3. Train Sharpe not worse (both-windows consistency)  
+
+Always report whether validation ΔSharpe exceeds **1 × SE** (expect most will not).
+
+Mechanics guards confirmed before reading results: calendar truncation asserted on every arm; next-open re-anchors stop to fill − 1.5×ATR(signal); vol scalars apply at entry only.
+
+---
+
+## Control baseline
+
+| Window | Sharpe | SE | CAGR | MaxDD | Calmar | Trades |
+|---|---:|---:|---:|---:|---:|---:|
+| Train | 1.75 | 0.68 | 49.8% | 17.9% | 2.78 | 240 |
+| **Validation** | **1.68** | **0.72** | **41.6%** | **20.9%** | **1.99** | **239** |
+| Full (close-fill) | 1.77 | 0.50 | 48.3% | 21.6% | 2.23 | 472 |
+
+**Capacity correction (2026-08-05):** the full close-fill control also records
+skipped_book_full = 519 versus 472 admitted trades, so the ten-slot book
+refuses 52.4% of admitted+blocked qualified opportunities. The older weekly
+claim that the cap never bound is stale and does not apply to this daily
+gate-reset configuration. Capacity is now isolated in the
+[focused bracket study](portfolio-capacity-bracket.md).
+
+Validation SE ≈ 0.72 — almost no arm clears a 1-SE delta.
+
+---
+
+## Per-arm decisions
+
+### A2 — Max hold {30, 45, 60, 90} — **note and move on**
+
+| Hold | Val Sharpe | Val DD | Train Sharpe | Trades train |
+|---:|---:|---:|---:|---:|
+| 30 | 1.68 | 20.9 | 1.75 | 240 |
+| 45 | **2.07** | 19.3 | **1.43** | 218 |
+| 60 | **2.12** | 19.3 | **1.11** | 186 |
+| 90 | 2.04 | 23.1 | 1.30 | 179 |
+
+Validation-only would have “found” +0.4 Sharpe. Train collapses: longer holds leave stale names blocking slots (240 → 186 trades at hold-60). This is a **regime interaction** (trend validation vs chop train), not a free knob. A regime-conditional hold is a large research program; prior regime-overlay work already argues against that path.
+
+**Decision: keep max hold 30. Do not ship longer static holds.**
+
+### A3 — Equity-curve vol targeting — **reject as edge; park as optional insurance**
+
+Scalars averaged 0.77–1.07 as designed (grid straddled historical book vol ~22–25%). Lower targets de-levered; **vt25** was nearly neutral (val Sharpe 1.63 vs 1.68). Wide clamp ≈ headline clamp. Lookback sensitivity did not unlock a win.
+
+This sample has **no major vol-regime shift**, so the run **rejects vol targeting as an edge on this data** — it does **not** reject crash-insurance value in a future high-vol regime. The ~0.02 Sharpe cost at vt25 is a nearly free insurance policy if drawdown tolerance ever tightens.
+
+**Decision: do not ship. Settles “Phase 2 = vol-scaled momentum” as an edge plan on this snapshot. Park vt25 as optional risk preference only.**
+
+### A5 — Correlation caps — **reject; sector caps stay Phase B with reduced expectations**
+
+Best near-miss: **0.6 skip** — val Sharpe 1.70, val DD **17.0%** (tempting), but train Sharpe 1.61 < 1.75 and full-period Sharpe **1.59 vs 1.77** (the cap deletes real momentum concentration profit). Half-size variants were worse.
+
+**Decision: no pure corr cap. Sector caps remain Phase B with reduced expectations.**
+
+### A4 — Next-open fill — **not a reject; the discovery**
+
+| | Close control | Next-open |
+|---|---:|---:|
+| Full Sharpe | 1.77 | **1.20** |
+| Full CAGR | 48.3% | **30.0%** |
+| Val Sharpe | 1.68 | 1.44 |
+| Val DD | 20.9% | **28.2%** |
+
+Overnight gap on validation entries: mean **−0.52%**, median −0.18%, p05 −4.5%, p95 +2.1% (n=243).
+
+This is not “slippage noise.” It is largely the **overnight momentum drift** that close-fill earns and a 07:00-Berlin scanner (signal yesterday’s close → fill tomorrow’s open) **structurally cannot**. Honest deployable number under that schedule is ~Sharpe 1.2 / CAGR 30%, not 1.77 / 48%.
+
+**Decision baseline going forward (until near-close ships):** grade **promotion** under
+`fill_mode=next_open`; keep close-fill as the historical control for comparability
+with prior reports.
+
+**Follow-up (done):** execution recovery matrix — see
+**[execution-recovery.md](execution-recovery.md)**. Short version: monotone fill-timing
+gradient + DD recovery prove this is *when you fill*; live bracket **[1.57, 1.77]**;
+gap-cap dead; no more fill-timing sim on this snapshot; ops move R:R scan to NY
+near-close (one scan/day).
+
+### `fip_id` re-derivation — **validated**
+
+Weekly IC fingerprint on this snapshot: **mean IC −0.045, t = −2.92**, reliable (35 weeks). Matches the July record. Safe to reuse when the universe broadens.
+
+---
+
+## Promotion table (rule as written)
+
+| Outcome | Arms |
+|---|---|
+| Promote | only `a2_hold_30` (identity with control) |
+| Reject | every other arm |
+
+No arm cleared ΔSharpe > 1 SE.
+
+---
+
+## What not to do next
+
+- Re-litigate rejected-table items, min_rr, GTL  
+- Regime-conditional max-hold as a “small” experiment  
+- Treat validation-only max-hold glitter as a free CAGR lift  
+- Ship vol targeting as edge without a vol-regime sample  
+- More fill-timing simulation on this snapshot (settled — see execution-recovery.md)  
+- Dual daily qualifying scans (would break gate-reset validation)  
+- Gap-up entry filters (third tail-trim failure)  
+
+## What to do next
+
+1. **Ship near-close execution** — ops checklist in [execution-recovery.md](execution-recovery.md)  
+   (one R:R scan/day in `America/New_York`, MOC window, partial-bar honesty).  
+2. Until that ships: **decision baseline = next_open**.  
+3. Strategy work (nasdaq_all, fip_id, sector) only **after** execution path is decided,
+   graded under the fill mode you will trade.

+  `dc3f5de25eb0a156ce51d0025c90e04ac0977e9502dec47bcf1b25bdcf609c81`.
+
+The run completed 78 empty-book paths, 97 warm-seed paths, seven annual
+clusters under both protocols, two cost levels, four arms, and 1,400 cells with
+no validation errors. The construction universe was 505 priced tradable
+symbols plus 4,149 priced rank-only symbols.
+
+## Capacity is economically free
+
+The clean capacity treatment is `cap15_incumbent`: it changes no sizing or
+admission rule. Its cap never bound in any cell (maximum observed position count
+12; zero full-book skips), so it absorbed every opportunity blocked by cap 10.
+
+At 0.10% per fill, split the 175 paths by whether the paired control recorded
+any `skipped_book_full`. Values below are mean paired changes in net EV per
+trade, in R:
+
+| Arm | Cap never bound (n=70) | Cap did bind (n=105) |
+|---|---:|---:|
+| `cap15_incumbent` | +0.0000 | +0.0018 |
+| `cash_unbounded` | +0.0714 | +0.0077 |
+| `cap10_weekly_top10` | -0.0246 | -0.0426 |
+
+The exact zero for cap15 in the never-bound stratum is also a harness validity
+check: when the treatment cannot act, results are identical. Where it does act,
+giving the strategy every slot it requested adds only 0.0018 R/trade. The old
+519-blocked-versus-472-admitted count was true, but it did not imply that the
+blocked opportunities were economically valuable.
+
+Decision: **keep the production cap at 10.** Do not remove it or raise it in the
+expectation of additional edge.
+
+## The positive arm measured the risk floor
+
+`cash_unbounded` combined two treatments: no count cap and a 0.5% minimum
+effective initial-risk fraction. Its EV effect is roughly nine times larger in
+the 70 paths where the control cap never bound, so capacity cannot explain the
+improvement.
+
+Within that never-bound stratum:
+
+| Measure | Control | `cash_unbounded` |
+|---|---:|---:|
+| Mean trades | 75.7 | 69.9 |
+| Mean cash | 27.8% | 28.2% |
+| Mean gross exposure | 72.2% | 71.8% |
+| Mean hold | 15.4 sessions | 15.6 sessions |
+| Mean EV | +0.328 R | +0.399 R |
+| Mean profit factor | 1.60 | 1.75 |
+
+The floor removes about 8% of fills while leaving exposure and holding time
+nearly unchanged. This is selection, not general de-risking: candidates that
+available sizing compresses below half the intended risk are worse on average.
+The report records repeated reject attempts, not the rejected candidates'
+ranks, so whether the effect is rank-mediated remains unknown.
+
+Next research: one single-variable A/B, `cap10_incumbent` versus cap 10 with
+`min_initial_risk_fraction=0.005`, with every other rule unchanged. Do not call
+the current `cash_unbounded` result causal evidence for that floor until this
+confound-free comparison is run.
+
+## Weekly replacement hurts
+
+Median paired deltas read zero because enough cohorts are inert. The distribution
+is not neutral:
+
+| Protocol | Mean ΔEV | P25 ΔEV | Identical paths |
+|---|---:|---:|---:|
+| Empty book | -0.0360 R | -0.0817 R | 27/78 (34.6%) |
+| Warm book | -0.0348 R | -0.1582 R | 14/97 (14.4%) |
+
+The arm made 2,170 replacements and 529 same-symbol re-entries within ten
+sessions, so 24% of replacements were associated with short-horizon churn.
+
+Decision: **reject weekly top-10 replacement.** Future reports should show mean
+paired effects and identical-path fractions beside medians whenever treatments
+are inert in a material share of cohorts.
+
+## Warm dispersion was mostly structurally degenerate
+
+For six of seven anchors, control EV IQR is numerical zero (approximately
+`1e-16`) and Calmar IQR is exactly zero. The displayed ratio `1.000` is therefore
+mostly the implementation's zero-over-zero convention, not evidence of equal
+nonzero dispersion.
+
+Two mechanics cause convergence: sizing and notional limits are fractions of
+equity, making R and ratio metrics scale-invariant; and the 30-session maximum
+hold is shorter than the 63-session minimum seed offset, allowing initial books
+to wash out before the anchor.
+
+The exception is 2023. Control measurement-start positions vary from 6 to 9,
+EV IQR is 0.0274 R, and Calmar IQR is 0.2675. The protocol therefore carries
+state correctly, but its chosen offsets usually erase the initialization effect
+it was intended to measure.
+
+Future initialization studies should use seed offsets shorter than maximum hold,
+approximately 5–25 sessions. The current empty-book cohorts remain the primary
+start-date evidence, but they necessarily mix initialization with market regime.
+
+## Final decisions
+
+1. Keep cap 10; its measured opportunity cost is negligible.
+2. Reject weekly rank replacement.
+3. Do not interpret the `cash_unbounded` improvement as a capacity effect.
+4. Run only the focused cap-10 effective-risk-floor A/B next.
+5. Report means, inert fractions, and absolute dispersion beside medians and
+   ratios in future sparse-treatment studies.
