#2157: latent diffusion trained the denoiser on raw input

LatentDiffusionModelBase passed the training sample to the scheduler unchanged. A caller who passed images therefore trained the denoiser on pixels, while Generate runs it on latents. On master, training a latent model on an image does not run at all: it throws a shape mismatch.

PrepareTrainingSample now encodes an image-shaped sample ([B, VAE.InputChannels, H, W] or [C, H, W]) with the frozen first stage, as Rombach et al. 2022 §3.3 does (posterior sample, scaled). It matches what EncodeToLatent does for inference.
A sample that is already a latent is used as is.
Models that override the hook (UpscaleAVideo, DiffusionAutoML) keep their own.
Tests: an image reaches the denoiser as [1, LatentChannels, H/f, W/f], and a latent passes unchanged. The first test fails on master.

#2151: text conditioners had no layers before a forward

Fixed on master by 1aa1d15bd, which did not close the issue and added no test. This PR adds TextConditionerEagerLayersTests: all eight conditioners must report layers straight after construction. Removing CLIP's eager InitializeLayers() makes it fail.

#2290: models ignored `Options.Seed` (much wider than reported)

Building every financial model twice with the same Options.Seed showed that only 9 of 90 neural finance models reproduced their initial weights. The cause: layer initialisation draws its seeds from LayerInitializationSeedScope, which NeuralNetworkBase's constructor resets from Architecture.RandomSeed alone.

NeuralNetworkBase.Options now applies Options.Seed (ApplyOptionsSeed). Constructors assign their options before building layers, so the construction scope restarts from the seed. An explicit architecture seed still wins. This change alone fixed 81 models.
Two layers had unseeded random sources:
- MambaBlock drew its dt init from CreateSecureRandom(), which affected Mamba and TimeMachine.
- RWKV7Block initialised four LoRA matrices with a bare OrthogonalInitializationStrategy, which affected RWKVForecaster.
Both now draw from the layer's own seeded stream.
GraphAttentionPortfolio and SignatureInformedTransformer now assign Options before building their layers.
Breaking change, by decision (delete rather than obsolete): the 24 options classes that declared RandomSeed beside the inherited ModelOptions.Seed lose it.
- Every reader now uses Seed: 53 sites in src, 105 in tests, and one sample.
- ObjectDetectionOptions and TimeSeriesIsolationForestOptions keep their historical default by starting Seed at 42.
Tests:
- FinanceModelSeedTests: the same seed gives identical initial weights for every neural finance model. On the eight transformers named in the issue, different seeds differ and an architecture seed wins. That is 111 cases, and 94 of them fail on the unfixed code.
- The finance integration suite passes 1016/1016.
- The finance test factory now picks a constructor that takes options when a test configures them. The parameterless constructor had made the portfolio models look unseeded.

#2093: FastSpeech2 training was invisible to CI

The reported divergence (9.66 → 15.63) no longer reproduces. A fixed (input, target) pair trains from 11.88 to 1.30 over 40 steps, and clean master gives the identical trajectory. It was fixed on master before this branch, most likely by the 2026-09-06 paper-optimizer rework. What remained was how it had been hidden:

FastSpeech2 leaves the HeavyTimeout list. Its 33 generated tests run in 2 minutes, the slowest in 24 s against a 120 s gate. The tag had been suppressing a correctness failure, not a timeout.
Its training probes ran one step, which cannot show a trajectory. Training_ShouldReduceLoss and the MoreData probe now run 12 steps, past a measured step-4 bump. The strictly decreasing memorization probe keeps 2. FastSpeech (v1) is unchanged, because it was not measured.

Not included

#2138 (35 models declaring a category without its interface) needs its own PR. #2290's caller migration used most of the 100-file budget.

Verification (local, `AIDOTNET_DISABLE_GPU=1`)

Builds: net10.0 src and tests; the net8.0 + net471 compat build of the whole solution; ParameterSweepWorker; Serving.Tests. All were re-run after merging master (80 commits, including fix(timeseries): honour Options.Seed in the deep time-series models; stop N-BEATS blocks sharing initial weights #2285's time-series seeding), with no conflicts and zero errors.
Regression tests fail on the unfixed code: fix: latent diffusion models train the denoiser on the raw input, never on the vae latent #2157's image test, TextConditioningBase defers layer construction, so conditioners report no parameters before a forward #2151's CLIP case, and Finance forecasting transformers ignore both Options.Seed and Options.RandomSeed #2290's 94 seed cases.
Post-merge test run: the system stopped it for low memory after 178 tests had passed with 0 failures, so CI is the complete run.

Summary by CodeRabbit

New Features
- Latent diffusion training supports image samples, which are encoded into VAE latents, and pre-encoded latent samples.
- TimeGrad now provides autoregressive forecasts with uncertainty estimates. Diffusion-TS now offers context-conditioned forecasts, including quantile and interval predictions in native mode.
Bug Fixes
- Configured seeds are applied more consistently across model initialization, training, evaluation, and sampling to improve reproducibility.
Compatibility
- Randomization options now use Seed instead of RandomSeed; update existing configurations and samples.
- Diffusion-TS options and forecasting interfaces have changed; previous decomposition controls and Forward are no longer available.

… image LatentDiffusionModelBase handed the training sample to the scheduler unchanged, so a caller who passed images trained the denoiser on pixels while Generate runs it on latents (Rombach et al. 2022, section 3.3, train on z = E(x)). On master, training a latent model on an image does not even run: it throws a shape mismatch. PrepareTrainingSample now encodes an image-shaped sample ([B, VAE.InputChannels, H, W] or [C, H, W]) with the frozen first stage (posterior sample, scaled, as EncodeToLatent does for inference) and leaves a latent as it is. Models that already override the hook (UpscaleAVideo, DiffusionAutoML) keep their own. Tests: an image-shaped sample reaches the denoiser as [1, LatentChannels, H/f, W/f]; a latent is used unchanged. The first fails on master. Closes #2157 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…forward Regression test for #2151. The fix (1aa1d15, on master since 2026-09-10) builds each conditioner's stack in its own constructor, but added no test and did not close the issue. All eight conditioners now must report layers straight after construction; removing CLIP's eager InitializeLayers() call fails it. Closes #2151 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…RandomSeed properties #2290 reported that the finance transformers ignore Options.Seed. Building every financial model twice with the same seed showed the scope was wider: only 9 of 90 neural finance models reproduced their initial weights. Layer initialisation draws its seeds from LayerInitializationSeedScope, which NeuralNetworkBase's constructor resets from Architecture.RandomSeed alone, so a seed that arrived through the options never reached the layers. - NeuralNetworkBase.Options now applies Options.Seed when set (ApplyOptionsSeed): constructors assign their options before building layers, so the construction scope restarts from the seed. An explicit architecture seed still wins. This alone fixed 81 models. - MambaBlock drew its dt init from RandomHelper.CreateSecureRandom(), and RWKV7Block initialised four LoRA matrices with a bare OrthogonalInitializationStrategy; both ignored the layer's seed. They now draw from the layer's own seeded stream (Mamba, TimeMachine, RWKVForecaster). - GraphAttentionPortfolio and SignatureInformedTransformer stored their options without assigning Options; they now assign it right before building their layers. - The 24 options classes that declared RandomSeed beside the inherited ModelOptions.Seed lose it (breaking, by decision: delete rather than obsolete). Every reader now uses Seed - 53 sites in src, 105 in tests, one sample. ObjectDetectionOptions and TimeSeriesIsolationForestOptions keep their historical default by starting Seed at 42.

…probes a real trajectory #2093 reported FastSpeech2's training loss rising (9.66 -> 15.63) while CI stayed green: every FastSpeech2 test was HeavyTimeout-tagged out of the PR gate, and the nightly heavy lane meant to run them was red. The divergence itself no longer reproduces: a fixed (input, target) pair trains from 11.88 to 1.30 over 40 steps, and clean master gives the same trajectory, so it was fixed on master before this branch (most likely by the 2026-09-06 paper-optimizer rework).

Its 33 generated tests run in 2 minutes, the slowest in 24 s against a 120 s gate; the tag was applied for timeouts and was suppressing a correctness failure instead. - Its training probes ran ONE step, which cannot show a trajectory.

Walkthrough

The changes consolidate option-level random seeds under Seed across runtime code, options, tests, and examples. They also add image-to-latent preparation for latent diffusion training, replace the TimeGrad and DiffusionTS forecasting implementations, and update neural-network seed propagation and generated test scaffolding.

Changes

Seed Configuration and Reproducibility

Layer / File(s)	Summary
Seed option contracts and copying `src/Models/Options/*`	Options remove `RandomSeed` properties and update copy operations and selected defaults to use `Seed`.
Seed consumption across runtime paths `src/AdversarialRobustness/...`, `src/Classification/...`, `src/ComputerVision/...`, `src/CrossValidators/...`, `src/AutoML/...`, `src/FineTuning/...`, `src/Models/Results/AiModelResult.cs`, `src/Optimizers/...`, `src/TimeSeries/...`, `src/AiModelBuilder.BuildPipeline.cs`	Runtime paths now read `Seed` for random generation, sampling, serialization, hashing, batching, feature explanations, and federated learning.
Neural-network seed propagation `src/NeuralNetworks/NeuralNetworkBase.cs`, `src/NeuralNetworks/Layers/`, `src/Finance/Portfolio/`, `tests/AiDotNet.Tests/IntegrationTests/Finance/`, `tests/AiDotNet.Tests/UnitTests/NeuralNetworks/`	`NeuralNetworkBase` applies the options seed unless an explicit architecture seed is set. SSM layers can initialize from a seed assigned after construction when their parameters remain unchanged. Tests cover these initialization paths.
Seed migration in tests and examples `samples/time-series/AnomalyDetection/`, `tests/AiDotNet.Tests/AdversarialRobustness/`, `tests/AiDotNet.Tests/FederatedLearning/`, `tests/AiDotNet.Tests/IntegrationTests/`, `tests/AiDotNet.Tests/UnitTests/*`, `src/AiDotNet.Playground/Services/ExampleService.cs`	Tests and examples now set or assert `Seed` instead of `RandomSeed`. Existing seed values and assertions remain in place.

Latent Diffusion Training Inputs

Layer / File(s)	Summary
Prepare image and latent training samples `src/Enums/DiffusionTrainingSampleSpace.cs`, `src/Models/Options/DiffusionModelOptions.cs`, `src/Diffusion/LatentDiffusionModelBase.cs`, `tests/AiDotNet.Tests/UnitTests/Diffusion/LatentDiffusionTrainingSampleTests.cs`, `tests/AiDotNet.Tests/ModelFamilyTests/Base/*`, `tests/AiDotNet.Tests/ModelFamilyTests/Diffusion/ImagenModelTests.cs`, `.github/test-shards.yml`	Added an option to select image or latent training samples. Image samples are validated and encoded with the VAE before training; latent samples are validated and passed through. Tests cover sample shapes, defaults, and invalid channels.

Diffusion Forecasting Models

Layer / File(s)	Summary
TimeGrad recurrent diffusion flow `src/Finance/Forecasting/Foundation/TimeGrad.cs`, `src/Finance/Forecasting/Foundation/TimeGradNetwork.cs`, `src/NeuralNetworks/Layers/LSTMLayer.cs`, `src/Models/Options/TimeGradOptions.cs`, `tests/AiDotNet.Tests/UnitTests/Finance/TimeGradNetworkTests.cs`	TimeGrad now uses a recurrent encoder and conditional diffusion denoiser. Training prepares teacher-forced noisy targets. Native inference samples autoregressive paths and supports quantiles.
DiffusionTS window denoising flow `src/Finance/Probabilistic/DiffusionTS.cs`, `src/Finance/Probabilistic/DiffusionTSNetwork.cs`, `src/Models/Options/DiffusionTSOptions.cs`, `src/Enums/DiffusionReconstructionLoss.cs`, `tests/AiDotNet.Tests/UnitTests/Finance/DiffusionTSNetworkTests.cs`	DiffusionTS now predicts clean context-plus-horizon windows. It supports L1 or L2 reconstruction loss, optional Fourier loss, context-preserving reverse diffusion, and native quantile forecasts.

Generator and Test Scaffolding

Layer / File(s)	Summary
Resolve virtual layer initialization calls `src/AiDotNet.Generators/LayerStructureInitializationAnalysis.cs`, `tests/AiDotNet.Tests/Generators/ParameterGeneratorSemanticTests.LayerStructure.cs`	Generator analysis now visits exact-owner virtual implementations and virtual instance-property accessors. Semantic tests include empty and child-building virtual calls.
Update generated model fixtures and checks `src/AiDotNet.Generators/TestScaffoldGenerator.cs`, `src/AiDotNet.Generators/DefectBaselines.cs`, `src/AiDotNet.Generators/ModelDefectBaselines.cs`, `tests/AiDotNet.Tests/UnitTests/Diffusion/Conditioning/TextConditionerEagerLayersTests.cs`, `.github/test-shards.yml`	Generated smoke fixtures add bounded TimeGrad and DiffusionTS cases. FastSpeech2 iteration settings change, and a new test checks conditioner layers before a forward pass.

Merge Risk: 🟡 Moderate · up to c410b

This change unifies seeding and rebuilds two diffusion forecasters. Several seed-propagation and training-objective issues remain open. They can make runs non-reproducible, override seeds that callers set explicitly, or check gradients against the wrong objective. Resolve these before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to c410b

Public configuration and saved-state contracts change substantially. Existing checkpoints may become unusable after upgrade, affecting recovery. No new privilege or data-access bypass was established in the inspected changes, but coverage remains incomplete.

Retained concerns

Medium · reliability · inferred: The replacement forecasting graph imposes a different layer topology without an identified legacy-checkpoint migration path. Generic restoration reconstructs the saved layer list, but the new binding contract rejects incompatible counts or layouts. Existing checkpoints can therefore become unusable during upgrade or recovery. This is a static compatibility inference; a legacy checkpoint was not executed.

Security review details

Security Blast Radius

inferred — The evidenced exposure is through in-process library callers supplying tensors, configuration, layers, or checkpoints. Shared base changes affect multiple dependents, but the available evidence does not establish a tenant, service, credential, or infrastructure-wide attack boundary.

Trust Boundaries and Controls

observed — Inspected caller-to-computation paths enforce tensor layout and target-length contracts. Native-only quantile forecasting is explicitly rejected in ONNX mode, and incompatible supplied layer layouts are rejected before graph use.
observed — The changed initialization-analysis entrypoints belong to an internal compiler-operation analysis with a private walker. The inspected change resolves virtual implementation symbols; it is not evidence of a newly exposed runtime service endpoint.

Resilience and Maintainability Implications

inferred — Binding validation prevents silent execution of an incompatible restored graph, but fail-closed rejection can still leave recovery blocked when an older checkpoint is the available recovery state. This is a recovery compatibility concern, not an established authorization bypass.

Hardening Proposals

proposed — Define a versioned forecasting-checkpoint compatibility policy, validate topology and semantic configuration before committing restoration, and provide either a supported migration or an explicit retraining and rollback procedure.

Full details: Linked Issues check

Explanation

[#2157] The new hook encodes the first training input, which matches the issue’s described raw-input bug. However, latent samples pass through only when TrainingSampleSpace is set to Latent; the default is Image, so existing latent callers can be rejected or encoded as images. This does not preserve the issue’s stated latent-input behavior. [#2151] The new test checks LayerCount only. It does not check pre-forward parameter access, which the issue identifies as a broken invariant. [#2290] Seed wiring and reproducibility tests address initialization, but the PR deletes duplicate public RandomSeed properties instead of retaining obsolete aliases that forward to Seed, as the issue proposes. [#2093] The PR reports that the loss trajectory was already fixed on master; it extends the probes and reports removing FastSpeech2 from HeavyTimeout, so it does not claim an unimplemented training fix.

Resolution

For [#2157], preserve the existing latent-input behavior without requiring callers to change the default option, and test both image and latent training inputs. For [#2151], assert that parameters are available before a forward pass for all eight conditioners. For [#2290], retain the duplicate RandomSeed properties as obsolete aliases to Seed.

Full details: Out of Scope Changes check

Explanation

The PR replaces the TimeGrad and DiffusionTS forecasting implementations, changes their training and inference algorithms, and removes public APIs, including Probabilistic.TimeGrad and DiffusionTS members. The linked issues concern latent diffusion training samples, text-conditioner layer visibility, seed handling, and FastSpeech2 test visibility. The summaries do not establish a connection between these finance-model rewrites and those requirements.

#2269 (merged after this branch's first master merge) reads ObjectDetectionOptions.RandomSeed, which #2290 deletes. ObjectDetectionOptions.Seed starts at 42, the old RandomSeed default, so behaviour is unchanged; DetectionSeedingTests passes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- LatentDiffusionModelBase: a sample is an image when its channels match the VAE's input channels, even where that equals the latent depth. Imagen, DALL-E 2 and DeepFloyd IF use 3 and 3, and their first stage still downsamples by 4, so the old exclusion trained those denoisers on pixels while they generate in the latent space. - MambaBlock / RWKV7Block: built into an explicit architecture layer list, they initialise before the network opens its seed scope. LayerBase gains OnRandomSeedAssigned; both record a fingerprint of their unseeded constructor init and redo it from a seed assigned later, only while the parameters are still exactly the constructed ones (trained, loaded or set weights are kept). SsmLateSeedInitializationTests covers both behaviours. - NeuralNetworkBase.Options applies the options seed only while the model has no layers yet, so a later reassignment cannot restart the scope and hand new layers seeds earlier layers used. - XML crefs to the deleted RandomSeed now name Seed (RandomizedSmoothing, and TextDetectorBase and OCRBase, which #2269 added).

…ion model DiffusionTS trained its Layers as a regression head while Predict ran a sampler with no timestep input that wrapped its noise output with `i % length`, so training never trained what forecasting ran; its training invariants passed at 2 of 7 seeds. Rebuilt after Yuan & Qiao 2024 and the authors' interpretable_diffusion/transformer.py: - DiffusionTSNetwork: a 3-tap convolutional embedding, encoder blocks (AdaLN from the sinusoidal step embedding -> self-attention, LayerNorm -> GELU MLP) and decoder blocks that add AdaLN cross-attention, then split a time-mixing projection into a TrendBlock (cubic polynomial basis) and a FourierLayer (the int(ln K) strongest frequencies, extrapolated), remove the block mean into a level head, and sum trend + seasonality + residual. The DFT and the top-k selection are recorded engine operations. - The network predicts x_0. PrepareTrainingPair draws k and eps from (seed, draw) over the standardised [context | horizon] window and packs the reference objective (reconstruction plus sqrt(L)/5 times the Fourier term, reweighted per step) so the configured L1 or L2 loss over the row reproduces it. - Forecasting generates the whole window: each reverse step predicts x_0, clamps it, samples the posterior and re-imposes the observed context at the next noise level. Quantile forecasts sample instead of being unsupported. - Options take the reference defaults (d_model 64, 3 + 2 blocks, 500 cosine steps, L1) and stay configurable; BetaSchedule is the enum and the loss is DiffusionReconstructionLoss. All 36 generated tests pass and the training invariants pass at all 8 swept seeds. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Clear a prior options seed when the new options have no seed.

If a derived constructor assigns seeded Options and then assigns options with Seed = null before adding layers, ApplyOptionsSeed returns without clearing _optionsSeed or the construction seed scope. The final unseeded options therefore still initialize layers with the earlier seed. This is a blocking configuration defect. Clear the stored options seed and reset the scope when the final options have no seed, while retaining explicit architecture-seed precedence.
Proposed correction
-            if (_layers is null || _layers.Count == 0)
-                ApplyOptionsSeed(value?.Seed);
+            if (_layers is null || _layers.Count == 0)
+                ApplyOptionsSeed(value?.Seed);
Update ApplyOptionsSeed to handle null by clearing _optionsSeed and resetting the construction scope to the architecture seed.

src/NeuralNetworks/NeuralNetworkBase.cs:7644
🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Preserve caller-assigned layer seeds during training.

If a caller sets RandomSeed on an architecture layer and supplies Options.Seed, this new effective-seed path runs WireLayerRandomSeedRecursive on the first training forward. That method assigns a new seed without the caller-seed check used by SeedCallerBuiltLayer. Training therefore ignores the caller's layer seed. This is a blocking reproducibility defect. Wire only layers whose seeds the model owns, and leave caller-assigned seeds unchanged.

As per path instructions, “Every PR must contain production-ready code”; a configuration value must not silently replace a caller's explicit choice.

…essor The child-independence proof resolved every virtual property on the owner to the exact type's override, including base.P, which is a non-virtual call to the base accessor. When that base accessor reached a hook the owner overrides to build a child, the proof could succeed by reading the override instead. base.P now visits the base accessors, and an abstract one is unprovable. ExplicitBasePropertyOverriddenByOwner covers it and fails without the fix. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

…yer seeds Two defects in this PR's seeding, from CodeRabbit's outside-diff review comments: - ApplyOptionsSeed(null) returned early, so options without a seed that replaced seeded ones before any layer existed kept initialising layers from the earlier seed. It now clears the stored seed, resets the construction scope to the architecture seed and un-seeds the caller-built layers the model had seeded. - WireLayerRandomSeeds, run at the first training forward, overwrote a RandomSeed the caller set on a layer they built. Caller-chosen seeds (set, not drawn from a scope, not given by the model) are now left alone; the wiring still draws for them so every other layer gets the seed it got before. Both new OptionsSeedReassignmentTests cases fail without the fix. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Addressing the two outside-diff findings in CodeRabbit's review 5422377587, which could not be posted as threads. Both are fixed in 6a8b820.

NeuralNetworkBase.cs:303: clear a prior options seed when the new options have no seed. ApplyOptionsSeed(null) used to return early. It now clears the stored options seed, resets the construction scope to the architecture's seed, and un-seeds the caller-built layers the model had seeded. Explicit architecture-seed precedence is unchanged. Test: UnseededOptionsReplacingSeededOnes_DropTheEarlierSeed.
NeuralNetworkBase.cs:7644: preserve caller-assigned layer seeds during training. WireLayerRandomSeeds now skips caller-built layers whose seed the caller chose: the seed is set, was not drawn from a construction scope, and was not given by the model, which is the same test SeedCallerBuiltLayer uses. It still draws a seed for those layers, so every other layer gets the seed it got before. Test: ACallerChosenLayerSeed_SurvivesTraining.

Both tests fail with the fix removed.
