The user should not need a tester corpus run per symbol. Every pattern
condition in Signals\Signal{MA,RSI,MACD,Ichimoku}.mqh anchors its reads on
`int idx = StartIndex()` with zero hardcoded indices (verified), so a
name-hiding StartIndex override + EvalShift(i) on CExpertSignalCustom makes
the EXACT live ladder code answer "what would you have fired at bar i" -
the silent-divergence trap that justified the DB corpus does not exist on
this path, and neither do the GMT-offset ambiguity, the DB row caps, or
the wipe procedure.
- CExpertSignalCustom: m_evalShift + StartIndex()/EvalShift() +
SweepPrepare(bars) (deep-resizes the shared price series); the four
classic signal classes override SweepPrepare to deep-resize their own
indicator buffers.
- CSignalMETA::BuildCorpusBySweep: per bar x per source filter, run
Direction() shifted, harvest the per-side pattern slots + netVote into
the same corpus arrays the DB loader fills; entry=bar open so
MetaPrepareEra's resolution matches at offset +0 with zero price error.
DB corpus remains the fallback when classic filters are disabled.
- Warrior_EA.mq5: META gets the enabled classic filters as candidate
sources (family ids match the descriptor one-hot).
- UseDatabaseRanking default false -> true (user request): a META chart
journals + ranks out of the box.
Workflow per symbol is now: attach ONE chart with AIType=META (optionally
Meta_ExportDataset=true for the offline pool) - candidates, labels,
training and export all happen in place, ~10 seconds of sweep instead of a
tester run.

Meta_ExportDataset input: with AIType=META the chart writes its complete
training set once per attach - every resolved+labeled candidate as
[barTime|family|pattern|side|won|NetInputWidth floats] using the SAME
window builder, descriptor and label caches pass 2 trains on, so offline
examples are byte-equivalent to the EA's own. Sidecar .meta.csv carries
layout + the geometry/BE the labels were computed at. Files land in
Common\Files\Warrior_EA\MetaExport\<sym>_<period>.f32.
This is the pooling architecture decision: multi-symbol training INSIDE the
per-chart God-class would be the riskiest surgery this codebase has seen;
instead each chart exports, the pooled head trains offline (small dense+BN
net, minutes on this box), is validated per-symbol under the same
chronological splits and coverage x (p - BE) gate, and only a WINNER gets
written back into a .nnw for the EA to load natively (format fully mapped).
Also turns every future meta experiment from a 20-minute tester cycle into
minutes of offline iteration.
Cost-model note for the record (user challenge, verified): spread is 0.099
ATR = ~2% of the 4.74 ATR trade width - tiny per bar, but expressed in
win-rate points it is 0.099/4.74 = 2.1pp, which is the measured base-vs-BE
gap and the size of the entire observed skill lift. Zero-spread relabeling
would put base == BE by construction. Multi-day holds additionally pay swap,
which the label does NOT charge - the true bar is higher, not lower.

The S2 verdict localized precisely: the meta head's edge x width (0.02 x
4.74 ATR = 0.095 ATR/trade) equals the measured spread (0.099 ATR/trade) -
real signal, consumed exactly by cost. The breakdown line adds: the lift is
LONG-ONLY (shorts anti-selected) and MA-family-strongest (67-70% traded win,
<1 sigma over BE on ~350 trades, best-of-32 cells - not family-wise
evidence).
Next experiment, pre-registered in Meta_Labeling_Design.md before any H4
data exists: SP500 H4 doubles ATR against a fixed spread, halving the cost
drag (~1.3pp) that the ~+2pp lift must clear. Same pipeline end to end;
deployability still decided by the unchanged 2-sigma gate. H3 (the honest
risk) is that the lift decays with timeframe as fast as cost does - the
tick-flow failure shape - which would close the single-instrument well and
leave cross-sectional pooling as the only lever.
Enabler fixed here: LoadMetaCorpus picked the LARGEST .db on disk, so an H4
chart would have adopted the (bigger) H1 corpus and resolved candidates onto
wrong bars - and a chart could even adopt another SYMBOL's corpus. The
loader now requires a <symbol>_<period>_ filename match and says so when
nothing matches.

The NN now has a target that is not per-bar direction (closed, best-of-999
p=1.0000): P(win | this journaled candidate, at the EA's own SL/TP, net of
cost). One net for all 52 pattern-sides, AIType=AI_META.
- NetForward.mqh: the host-side softmax+CE gradient generalized total==3 ->
2||3 on both backprop paths; a 2-class softmax IS a logistic head, and no
compute backend changes.
- SignalMETA.mqh (new): corpus loaded read-only from the LARGEST signal DB on
disk (decoupled from the config fingerprint that burned four S1 runs); the
GMT->server offset is measured PER ROW against entryPrice vs bar open
(DST-immune, histogram logged); a window-span regime filter drops the
pre-2017 daily-backfill rows; 31-feature setup descriptor appended at the
input (26 one-hot + side + tanh netVote + SL/TP ATR + spread/ATR).
- Training.mqh: candidate-queued pass 1, binary-target pass 2, per-candidate
calibration (2.5) and OOS (3) walks. Counter mapping win->Buy / loss->Sell
lets checkpoint selection, the edge floor, the plateau ladder and the
family-wise deploy gate run UNCHANGED: precision reads as win rate among
traded candidates, chance as the base win rate, recalls as sensitivity/
specificity. Era-end META line: coverage x (p - break-even) vs the null.
- Labels are the side-conditional triple-barrier win caches - never the DB's
stop-and-reverse outcome. Logit adjustment deliberately skipped (~40% base
rate). Live inference + online learning guarded off until S3.
- Fingerprint: conditional |TGT:META1; State\META\ folder + 2-output filename
slot keep meta models fully separate from direction models.
Compiles clean (0 errors, 0 warnings). S2 run = attach a chart with
AIType=AI_META; S3 wires the votes via the per-side hooks.
