CI only lints app/, so 11 findings had accumulated in tests/ and scripts/. Mechanical and behaviour-neutral, but two were not auto-fixable and needed a judgement call rather than `ruff --fix`: - E741 in run_fip_breadth_diagnostics: `l` is the OHLCV low and is genuinely used, so this was a naming fix (`l` -> `lo`), not a deletion. - F841 in the same file: `vol_ix`/`momr_ix` are assigned from a pure local `_index()` and never read, so removing them cannot change any output. Their upstream `vol_weeks`/`momr_weeks` maps *are* used further down and stay; the comment above `_index` was corrected to say so. The rest are unused imports and f-strings without placeholders (literal markdown table headers, so identical output). Verified beyond the linter, since py_compile does not catch a removed-but-used import: every removed symbol has zero remaining references, all scripts compile, and the full unit suite passes (852 passed, 1 skipped).

"""Phase-A research matrix: max-hold, vol targeting, next-open fill, corr caps.
|
||
|
||
Promotion rule (pre-registered — do not edit after a run starts)
|
||
----------------------------------------------------------------
|
||
An arm may be promoted over the close-fill production **control** only if ALL of:
|
||
|
||
1. Validation-window (entries ≥ ``--validation-split``, default 2024-07-01)
|
||
Sharpe ≥ control validation Sharpe.
|
||
2. Validation max drawdown is not worse than control by more than 2 percentage
|
||
points (higher DD is worse).
|
||
3. Train-window Sharpe is not worse than control train Sharpe (both-windows
|
||
consistency — same standard as the min_rr sweep).
|
||
4. Report whether the validation Sharpe delta exceeds 1 × SE (control or arm);
|
||
most arms will fail this distinguishability check — that is expected and is
|
||
the reason SE/PSR ship on every row. Failing the 1-SE bar does **not** alone
|
||
veto promotion under (1)–(3), but it must be stated.
|
||
|
||
Naming: the post-split window is called **validation**, not "holdout". It has
|
||
been opened by prior experiments; treat it as a disciplined check, not a
|
||
pristine sample.
|
||
|
||
Arms (pre-registered; N used for Deflated Sharpe)
|
||
-------------------------------------------------
|
||
- A0 control: production gate/rank/trail, hold=30, close fill, no vol target, no corr cap
|
||
- A2 max-hold: hold ∈ {30, 45, 60, 90} (30 is the control row; listed once)
|
||
- A3 vol-target: target ∈ {15%, 20%, 25%} × clamp {[0.5,1.5], [0.25,2.0]} at lookback 60;
|
||
plus sensitivity lookbacks {20, 126} at target 20% / clamp [0.5,1.5] only
|
||
- A4 next-open fill (measurement + portfolio consequence vs control)
|
||
- A5 corr cap: threshold ∈ {0.6, 0.7, 0.8} × action ∈ {skip, half-size}
|
||
|
||
DSR uses N = number of pre-registered strategy arms in this matrix (see
|
||
``PRE_REGISTERED_ARM_IDS``). Standalone backtests do not invent a DSR.
|
||
|
||
Calendar truncation
|
||
-------------------
|
||
The simulator always cuts the equity calendar at last_signal + hold_days
|
||
(+1 for next-open). The runner asserts validation end_date ≤ last price date and
|
||
that the sim end is within hold_days+pad of the last admitted signal so a 90d
|
||
arm cannot sit in trailing flat cash.

||
