Three backends left, as the operator specified: OpenCL, the CPU DLL,
and pure MQL5. CDirectMLMy was a two-tier wrapper (GPU via
WarriorDML.dll, CPU via WarriorCPU.dll) whose name only ever named the
tier being removed here; the CPU DLL tier - the one actually used on
the training machine (no OpenCL, no DirectML) - is untouched.
AI/NeuronDirectML.mqh -> AI/ComputeDll.mqh: dropped the DML_* #import
block and COMPUTE_TIER_GPU (checked first that nothing persists the
enum value and only one external site reads .Tier() - safe), collapsed
every tier==CPU?CPU_x():DML_x() ternary to a straight CPU_x() call.
Renamed CDirectMLMy->CComputeDll, InitDirectML()->InitComputeDll(),
member directml/DirectML->computeDll/ComputeDll across every AI/ file
that touched a neuron/net backend plus Topology.mqh/OnlineLearning.mqh.
NetBuild.mqh's InitComputeDll also lost the dead D3D12 error-code
switch and the now-impossible GPU-tier log branch.
Verified via per-file brace-balance diff against HEAD and a whole-repo
grep for every removed symbol (CDirectMLMy/InitDirectML/
COMPUTE_TIER_GPU/DML_*) - the only surviving hit is an intentional
historical-note comment in the new file's header.
DirectML\WarriorDML.cpp/.h and its build scripts are now orphaned C++
source, left in place pending an operator decision. Architecture docs
(AI_NETWORK.md, Warrior_EA_System_Overview.md, etc.) still describe the
4-backend/GPU-tier shape and are not updated in this pass.

The //| box blocks were excluded from 0b06f8e and 5efdb48 and were what
remained: 160 of them ran to 10+ lines, the longest to 88. Compressed to their
leading topic sentences - 5 lines for a function header, 8 for a file header -
keeping the box format and the standard MQL5 name/author lines verbatim.
Verified at the BYTE level this time, across every in-scope file: the list of
non-comment lines is byte-identical to HEAD and braces balance. The first check
compared a locale-decoded 'git show' against a UTF-8 read and flagged 25 files
that had not changed at all - every BOM and every non-ASCII line mismatched.
47,696 -> 40,665 lines in scope; comment share 38% -> 26%.

Both 2026-08-19 reports were the same staleness: every source behind the
label was an ERA artifact (live cache refills at pass-3 completion, the
snapshot copies once per era, dPrevSignal is the frozen purge-band edge
bar) - so the readout stepped at era cadence at best, stayed glued to
one direction, and lagged the era counter.
DisplayInference(): throttled (4s, 1s across an era boundary),
SIDE-EFFECT-FREE forward of the current decision bar (window ending on
bar 1, same question the live path asks) through the LEARNER net.
Batch-norm running stats are bracketed frozen/RESTORED via the new
CNet::GetBatchNormFrozen() + CNeuronBatchNormOCL::StatsFrozen() - restore,
not unfreeze, because a display tick can land between pass-3 chunks whose
whole scan holds them frozen. Writes nothing a trading or training path
reads (dPrevSignal, NMS state, tallies, watermarks all untouched;
RefreshLatestSignal is not reusable here precisely because it writes all
of them). LSTM safe by construction: h/c zeroed per forward.
ProspectiveVote() reads the fresh forward as its FIRST source; the
era-artifact chain becomes the fallback (meta head, warm-up, window
holes).
DisplayHudLine(): the reference library's training label, per ensemble
member - name, output activations (softmax probs or raw scalar), the
decision, its weighted vote (the exact consensus numerator term), era,
recent average error, "(trn)" while not vote-capable. Rendered under the
vote line in RefreshVoteReadout BEFORE the live-vote defer (member lines
are telemetry, not tradable readings), coloured by the member's own
direction in muted tones - the vote line's strict
green-only-when-it-would-trade rule is untouched.

Two defects behind the "training is highly unstable" report, from 101 eras of
SP500 H4 PAI logs. Neither was the optimizer.
1) LayerLearningReport's dW/W for BN layers divided by the WHOLE packed block.
getWeightsBN concatenates the outgoing dense matrix, gamma/beta, the running
mean/variance, the Adam moments AND BN_OPT_NX - the forward-pass scratch copy
of the normalized input. At era 101 bn1's dense matrix normed 15.1 against a
block norm of 15430.3, of which NX alone was 15429.3: the weights were 0.098%
of their own denominator, a 1022x inflation. NX is also near-constant between
era-end reports (same last forward pass), which pins the numerator down too,
so the layer read "bn1:0.000%" for 101 consecutive eras and was diagnosed as a
frozen first layer. It was the ruler that was broken. The ratio now covers
trainable parameters only (dense matrix + gamma + beta); mean/var/NX/Adam are
excluded. NX is reported separately because it is a health signal in its own
right - bn5 read nx 6.8e6 over 16 neurons, ~1.7e6 per unit against a healthy
~1.0, which is what a near-zero running variance in the denominator looks like.
NO historical dW/W reading on a bn* layer is admissible evidence that a layer
did or did not train. That includes every such claim in this repo's notes.
2) FitDirConfThreshold took a bare argmax of coverage x (precision - breakEven)
over 50 bins. Measured across 98 consecutive fits:
correlation(chosen threshold, win rate at it) = -0.056 over 0.00..0.74
win rate stdev across fits = 1.32pp
binomial SE of that win rate at ~1430 calls = 1.25pp
The correlation is zero - the margin does not rank trades - and the era-to-era
spread IS its own sampling error to within 0.07pp. So the objective was
coverage x (3.4 +/- 1.3) and the argmax over ~37 eligible bins returned
whichever bin drew the luckiest sample. The threshold teleported
0.42 -> 0.04 -> 0.74 in three eras, swinging OOS coverage 0% -> 39%, leaving
the era win rate measured on 1-5 calls and swinging 0% <-> 100%. That is the
entire reported instability.
The argmax is now adopted only if it beats a DETERMINISTIC fallback - the most
selective bin still clearing the coverage floor, chosen from the margin
distribution alone and never from a win rate - by more than a best-of-N
maximum could manage on noise, sqrt(2 ln N) standard errors. Same null-of-the-
maximum correction the deploy gate already applies to model selection.
A plain one-standard-error band was tried first and is NOT sufficient: its
edge is bestScore - bestSE, and with a 2.3pp edge against a 1.25pp SE that
edge is itself +/-50%, so the admitted set would still wander by half its own
width every era. The fallback has to be independent of the noisy quantity.
Simulated on the observed numbers: falls back every era at the current 2.3pp
edge (stable), adopts the argmax once a real edge reaches ~5pp.
NOT COMPILED - user compiles.

Completes the 2026-08-09 training audit. FORCES A RETRAIN of every
Wyckoff-enabled config (N1 re-keys the fingerprint), and BOTH DLLs must be
redeployed alongside the .ex5 - they carry new exports.
F4 - mini-batch accumulation, TRAIN_BATCH_SIZE=32. Training was pure online
SGD (one weight update per bar), which is the mechanical source of the
era-to-era whipsaw every downstream guard was built to cope with. The O(n^2)
outer product is native - AccumulateWeightGrad / AccumulateWeightGradConv /
AccumulateBufferInto in Network.cl, WarriorCPU and WarriorDML - while the
optimizer step is host-side MQL5 shared by all tiers (ApplyAccumToBlock), so
there is one Adam/SGD implementation instead of four that can drift.
- the LSTM needs no outer-product kernel (WeightsGradient already holds the
sample's full dW) but could NOT simply be left un-zeroed between samples:
CPU_LSTMSeqBackward/DML_LSTMSeqBackward memset it on entry. Hence a
separate accumulator plus an elementwise add.
- batch-norm gamma/beta accumulate in host arrays, not new BatchOptions
slots - BN_OPT_STRIDE is baked into every persisted .nnw.
- scoped to pass 2; online learning keeps immediate updates. Every save /
checkpoint / scoring boundary flushes, scaling by the real sample count.
- degrades to per-sample updates (one log line) on a tier that cannot
accumulate, so old devices and DLL-free builds are unaffected.
- verified offline: DirectML/batch_accum_check.cpp drives the real exports
against an independent reference; at B=1 the accumulator matches the
shipped unbatched kernel's own gradient to 1.1e-16. Math only - the
in-situ check remains the per-layer dW/W report on a real era.
F6 - ComputeFirstLayerWidth budgeted against the RAW input width even where a
conv/LSTM front end had already reduced it, so an LSTM's dense stack was
charged for 1,280 inputs when it receives 64. Confirmed from the deployed
.cfg files: CONV, LSTM and HYBRID were all pinned at the 16-unit floor. Now
budgeted against the front-end output and capped at it (never fan out), with
the derivation reordered so both stages settle first.
N1 - EventCode/EventPhase/StructuralPhase are signed categoricals packing
direction and Wyckoff stage into one scalar across a sign discontinuity. Split
into direction + [0,1] magnitude, the same convention the base OHLC block uses.
Information-preserving; 13 readings now occupy 16 inputs.
Compiled clean (0 errors, 0 warnings); both DLLs rebuilt.

Four of the six findings from research/training_pipeline_audit_2026-08-09.md
(F4 mini-batching and F6 feature re-encode deliberately deferred - see the
report's implementation-status section for why):
- F1: pass-2 Fisher-Yates (and AutoTune's MI block shuffle) used MathRand()%,
which is 15-bit - provably non-uniform on every full-history era over 32,768
queued samples. New 30-bit ShuffleRandomIndex().
- F2: plateau warm restarts were a no-op whenever eta already sat at its
ceiling (the normal state of a non-regressing plateau) - the ladder was just
a 24-era countdown. Restarts now overshoot to 5x the ceiling
(PLATEAU_RESTART_BOOST) and anneal geometrically back over the patience
window, SGDR-style; ETA_MIN widened 1e-4 -> 1e-5 so the decay schedule has
real range.
- F3: checkpoint restores put weights back but kept the rejected trajectory's
Adam moments, so the optimizer immediately pushed back toward the rolled-back
state (the restore->regress->restore oscillation). CNet::ResetOptimizerState()
zeroes moments/momentum/step counters (weights, BN statistics, gamma/beta
untouched) on every mid-run restore, every boosted restart, and the
deploy-time restore that online learning continues from.
- F5: batch-norm running statistics now freeze for the pass-3 OOS scoring walk,
so the selection metric the checkpoint ranking and deploy gate read is a pure
function of the checkpoint instead of partly measuring BN drift. Defensive
unfreeze in FinalizeTrainRun covers stop-mid-pass; live/online adaptation and
the OOS continual-learning simulation stay adaptive by design.
Compiled clean (0 errors, 0 warnings) via the staged-tree recipe.

The MI sample builder used `MathAbs(labelBarOffset)` as a padding, causing rows from offset and non-offset builds to be paired with a double shift. This broke the positive control, failed the 5× gate, and voided all reported mutual‑information figures. Replace with the fixed `MiShiftPad` constant to ensure builds enumerate the same set of bars and row-k alignment is preserved.
Add `BatchOptionsTotal()` to `CNeuronBatchNormOCL` and split the packed BN weight array in the learning report into separate norms for the outgoing dense matrix, gamma, beta, running statistics, and Adam moment buffers. This turns an ambiguous single‑norm reading into precise diagnostics that distinguish weight divergence from scaling issues.
- Moves CLayer neuron construction to AI/Impl/Layer.mqh to keep Network.mqh clean
- Unifies four previously duplicated architecture initialisation blocks (MLP/CONV/LSTM/HYBRID) into a single shared function
- Eliminates risk of behavioural drift where one architecture missed a setter, causing mismatched feature sets or targets
