feat(#2090): phase 3 — vision-language models read their Options - #2130

Conversation
Six family base classes, each declaring a model family's shared knobs once: - ModelHyperparameterOptions (new, Models/Options) — MaxGradNorm plus the Require() guards every family shares. - SequenceModelOptions, VisionLanguageModelOptions, EmbeddingModelOptions, GanOptions (new, NeuralNetworks/Options). - DocumentNeuralNetworkOptions — EXTENDED rather than replaced. All 29 Document options classes already derive from it, so adding the shared knobs there reaches the whole area without touching a leaf. - VideoHyperparameterOptions (new, Video/Options). Video has no base in use: 96 of its 108 options classes derive straight from NeuralNetworkOptions. Properties are non-nullable with no base default. A shared default would be wrong for nearly every model that inherits it — NumLayers = 12 is right for BERT and wrong for Mamba-130M. Per-model values go in each leaf's constructor in phases 2-7. Until a leaf is wired, Require() throws naming the property rather than letting a zero-width model through silently. The ratchet counts tunable defaulted constructor parameters that have no correspondingly-named property on their model's options type, resolving models by transitive reflection over NeuralNetworkBase<T> — BGE derives from TransformerEmbeddingNetwork, TrOCR from DocumentNeuralNetworkBase, and only 3 files under src/NeuralNetworks name the base directly, so no naming or path heuristic finds them. BASELINE IS 1067, not the 806 the spec estimated. The file-based estimate only looked at the three areas the spec named. Reflection also finds Tacotron2Model (20 params), TtsModel (17) and VITSModel (16) configured against a generic OnnxModelOptions, and SpeechEmotionRecognizer (11) with no options parameter at all. Those areas scored clean on "do their Options classes declare properties", which turns out to be a different question from "do the models read them". The behavioural assertion — that setting an options property actually changes the model — is written and skipped until phase 2, when the first family reads its options and there is something for it to assert against. Refs #2090 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Phase 1's ratchet measurement pulled TextToSpeech, SpeechRecognition and Audio into scope: 22 models carrying 192 tunable constructor parameters between them, including the three largest single offenders in the library (Tacotron2Model at 20, TtsModel at 17, VITSModel at 16, all configured against a generic OnnxModelOptions). The knobs are dominated by signal parameters rather than network shape — sampleRate appears in 21 of the 22 models — so they get their own base rather than being folded into an existing one. It spans three source areas, so it lives in Models/Options beside DocumentNeuralNetworkOptions. Canonicalises two pairs of synonyms the constructors currently use interchangeably: hopLength/hopSize and fftSize/frameSize. Build green, ratchet unchanged at 1067 — nothing inherits from this yet, which is correct until the wiring phases. Refs #2090 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
… config Establishes the per-model pattern for the sequence family: - MambaOptions derives from SequenceModelOptions and sets the model's shipped defaults in its parameterless constructor. - The constructor drops its six scalar parameters, taking (architecture, options, lossFunction) and reading every value off _options. - The hand-written positivity guards are replaced by MambaOptions.Validate(), which covers the same four values plus MaxSequenceLength and ExpandFactor. Values are carried over UNCHANGED. Mamba-130M is 768x24; this ships 256x4. Correcting that is phase 9, kept apart so behaviour changes are reviewed separately from the mechanical move. Build green, no call site in src passed the removed parameters. Refs #2090 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…riven config Moves each model's tunable ctor params onto its Options class, which now derives from SequenceModelOptions. Values are carried over UNCHANGED, read straight out of each ctor signature so nothing can drift in the move; verifying them against the papers is a later phase. Validation now throws ArgumentException naming 'options', preserving the public contract these constructors already had rather than changing it to InvalidOperationException as an incidental consequence of the move. RWKV7's model-dimension/head divisibility check is moved below the options assignment — repointing it at _options had put it above, where _options was still null. RWKV4's four hand-written positivity guards are removed as unreachable behind Validate(). Refs #2090 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The script that swapped <exception cref> tags filtered on 'has a Validate() method', which is far too loose: six files outside this work have their own Validate() that genuinely throws InvalidOperationException, and their docs were mislabelled as ArgumentException. Only the #2090 family bases keep the ArgumentException contract, which is the one their Require() actually throws.
Migrating 11 sequence models to options-driven configuration is a breaking change to every call site that passed the removed scalar parameters. The compiler enumerated them; there were 106 across 6 files plus the generator. - TestScaffoldGenerator: 8 construction snippets. Worth noting WHY they exist — the generator builds these models at reduced "scaffold scale" precisely because the production defaults are too large for CI (a 50,277-way LM head made one synthetic target 6.4M values). That is a legitimate use of the configuration surface, and it now goes through Options like everything else. - MambaLanguageModelTests, RWKV7LanguageModelTests: 40 call sites. - WeightImporterTests, RealModelLocalInferenceTests, LoRAFineTunerTests: 6. All 16 existing ArgumentException assertions still pass unchanged, which is the evidence that keeping ArgumentException over InvalidOperationException was the right call — the public contract of these constructors is unaltered. Ratchet 1067 -> 1004, exactly the 63 parameters moved. 88 model tests pass. Refs #2090 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…4 -> 977 Finishes the six models the earlier migration guard refused because their Options classes already declared a constructor: Finch, GLA, GatedDeltaNet, Griffin, Hawk, RecurrentGemma. These six also declare COPY constructors, and GLAOptions carries an explicit warning about them: a property missing from the copy constructor does not merely vanish from the clone — the clone silently reverts to the default while the original keeps its configured value, and nothing reports the divergence. CreateNewInstance calls it. Every property added here is therefore added to the copy constructor too (28 params, 27 new base properties, all copied). Call sites needed three shapes none of the earlier scripts matched: - `: base(...)` in test subclasses (4 sites) — hand-edited. - Generator blocks covering several models at once, where the options type differs per model within one block: Griffin/Hawk and Hawk/GLA/GatedDeltaNet now derive it from model.ClassName. - A third generator shape, `scaleArgs` appended to the architecture expression. Two escaping traps, both caught by the build: a replacement string containing "$1" must not be escaped, or the capture reference is emitted literally and the declaration is deleted; and "}}" collapses to one brace only inside an INTERPOLATED string, so the same text in a plain segment emits two. Build green. 93 tests pass, ratchet 977. Refs #2090 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Eleven multimodal models (CLIP, BLIP, BLIP-2, Flamingo, LLaVA, ImageBind, GPT-4 Vision, VideoCLIP, UnifiedMultimodal, and the two AudioVisual networks) now take their configuration through VisionLanguageModelOptions. 102 parameters moved, carried over unchanged. Three defects in my own tooling, each caught by the build rather than by care: 1. The migration handled only ONE constructor per model. Eight of these eleven declare two, and both contain `_options = options ?? new XOptions()`, so the script took the first and left the second's parameters in place — 44 params moved instead of 102. It now migrates every constructor that takes an options parameter, and the options class carries the union of their defaults. 2. Repointing a guard at _options could place it ABOVE the assignment, a null dereference. This happened in three different guard shapes (RWKV7 in phase 2, Blip2 and Flamingo here), so rather than recognising each shape the options assignment is now hoisted to the top of the constructor body. 3. Call sites received the options object as the last POSITIONAL argument, but the new signature puts `options` before the optional collaborators. It is now emitted as a named argument. Also handled: defaults that are `private const` on the model are resolved to their literal value with the constant's name kept as a comment; a default naming an open generic is reported rather than emitted into a non-generic options class. Known gap: enum- and string-typed parameters are not yet moved (VideoCLIP's TemporalAggregation, LLaVA's LanguageModelBackbone). The ratchet counts them, so they are covered in a follow-up rather than left implicit. Build green, ratchet 875. Refs #2090 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

In `@src/AiDotNet.Generators/TestScaffoldGenerator.cs`:
- Around line 6980-6988: Fix duplicate model.ClassName guards in
EmitGeneratedTestClass: remove HawkLanguageModel from the earlier
GriffinLanguageModel/HawkLanguageModel branch or merge this branch’s pin/
headArgument behavior there so Hawk reaches the intended logic; also remove the
shadowed XLSTMLanguageModel branch around line 6566 or merge its intended

Affected site: src/AiDotNet.Generators/TestScaffoldGenerator.cs lines 6980-6988
requires the Hawk guard/configuration fix; lines 6566-6566 requires the XLSTM
dead-branch removal or merge.
In `@src/Models/Options/AudioHyperparameterOptions.cs`:
- Around line 78-93: Update the XML documentation for HiddenDim, NumHeads,
NumEncoderLayers, and NumDecoderLayers to include value descriptions and remarks
containing a For Beginners paragraph, while preserving their existing summaries.
Add a Reference paragraph citing librosa to the class-level remarks.
- Around line 121-124: Update ValidateCore in AudioHyperparameterOptions to
validate NumMels, FftSize, and HopLength with the existing Require mechanism
alongside SampleRate, preserving the documented guarantee that required audio
signal parameters cannot remain unset.
- Around line 32-33: Add a protected
AudioHyperparameterOptions(AudioHyperparameterOptions other) copy constructor
that throws ArgumentNullException for null input and copies all ten properties
declared by AudioHyperparameterOptions, while preserving the existing default
construction behavior for derived classes.
In `@src/Models/Options/DocumentNeuralNetworkOptions.cs`:
- Line 42: Add a public parameterless constructor and a public copy constructor
to DocumentNeuralNetworkOptions. The copy constructor must reject null with
ArgumentNullException and copy all 14 configuration properties from the supplied
DocumentNeuralNetworkOptions instance, preserving the options copy-constructor
pattern used in the surrounding models.
In `@src/Models/Options/ModelHyperparameterOptions.cs`:
- Line 38: Remove the duplicate MaxGradNorm property from
ModelHyperparameterOptions and standardize gradient-limit usage on the existing
MaxGradientNorm property across all derived options, copy constructors, and
consumers. Ensure copy constructors continue copying the canonical property for
every options type, including FinchOptions.
In `@src/NeuralNetworks/AudioVisualEventLocalizationNetwork.cs`:
- Around line 177-178: Update the AudioVisualEventLocalizationNetwork
constructor so its scalar inputs are migrated into a single
AudioVisualEventLocalizationOptions instance, and build layers only from that
options object so GetOptions().EmbeddingDimension and layer dimensions cannot
diverge. Extend AudioVisualEventLocalizationOptions.Validate() to validate every
field used by this model, including NumEncoderLayers, without requiring
unrelated VisionLanguageModelOptions fields that default to zero. Validate the
completed options before calling
LayerHelper<T>.CreateAudioVisualEventLocalizationLayers.
In `@src/NeuralNetworks/Blip2NeuralNetwork.cs`:
- Around line 475-479: Update the Blip2 validation at
src/NeuralNetworks/Blip2NeuralNetwork.cs#L475-L479 to pass nameof(options) as
the ArgumentException paramName and use public Blip2Options property names
instead of private _options fields in the message. Apply the same parameter-name
correction and name FlamingoOptions.Channels in the message at
src/NeuralNetworks/FlamingoNeuralNetwork.cs#L252-L255.
- Line 351: Update the ONNX constructors so they use validated option values
instead of hardcoded literals: in
src/NeuralNetworks/Blip2NeuralNetwork.cs:351-351, use QformerHiddenDim,
VisionHiddenDim, LmHiddenDim, NumQformerLayers, NumHeads, NumQueryTokens,
PatchSize, and VocabSize; in src/NeuralNetworks/BlipNeuralNetwork.cs:292-292,
use HiddenDim, NumEncoderLayers, NumDecoderLayers, NumHeads, MlpDim, PatchSize,
and VocabSize; and in src/NeuralNetworks/FlamingoNeuralNetwork.cs:167-167, use
VisionHiddenDim, LmHiddenDim, NumVisionLayers, NumLmLayers, NumHeads, VocabSize,
NumPerceiverLayers, and LearningRate. Keep each constructor’s validated _options
and ensure GetOptions() reflects the values the model actually uses.
In `@src/NeuralNetworks/BlipNeuralNetwork.cs`:
- Line 397: Update the XML documentation for the BlipNeuralNetwork constructors
and ClipNeuralNetwork constructor: remove orphaned parameter tags for removed
scalar parameters and document the new options parameter with a matching param
tag. Apply this to both Blip constructors and the Clip constructor; affected
files are src/NeuralNetworks/BlipNeuralNetwork.cs lines 281-283 and 375-385, and
src/NeuralNetworks/ClipNeuralNetwork.cs lines 93-95.
- Line 406: Update BlipOptions.Validate, called by BlipNeuralNetwork, to reject
ImageSize values that are not evenly divisible by PatchSize, matching the guard
in Blip2NeuralNetwork. Preserve the existing positive-dimension validation and
ensure invalid pairs fail before patch-count or positional-embedding
calculations.
In `@src/NeuralNetworks/EagleLanguageModel.cs`:
- Line 72: Rename one of the conflicting public EagleOptions types to a distinct
name such as EagleSequenceOptions or EagleVisionLanguageOptions, then update all
declarations, references, and public API usage for that type. Do not add an
obsolete forwarding shim, and document the breaking rename in the migration
notes.
In `@src/NeuralNetworks/FlamingoNeuralNetwork.cs`:
- Line 247: Update FlamingoOptions.Validate() to require ImageSize to be
divisible by the fixed patch size used by FlamingoNeuralNetwork, and require
NumLmLayers to be at least 4. Preserve the existing positive-value validation
and report both invalid configurations through the established validation
mechanism.
In `@src/NeuralNetworks/LLaVANeuralNetwork.cs`:
- Line 196: Update the ONNX constructors in
src/NeuralNetworks/LLaVANeuralNetwork.cs lines 196-196,
src/NeuralNetworks/Gpt4VisionNeuralNetwork.cs lines 212-212, and
src/NeuralNetworks/ImageBindNeuralNetwork.cs lines 213-213 to use every
validated options property for model geometry, matching each class’s native
constructor instead of hardcoded values or mismatched fields. Add one test per
class that builds ONNX and native instances with identical non-default options
and asserts their geometry matches.
In `@src/NeuralNetworks/Options/AudioVisualCorrespondenceOptions.cs`:
- Around line 34-42: Update the XML documentation for AudioSampleRate and
VideoFrameRate to state each property's unit, valid range where applicable, and
the provenance of its default value (16000 and 25.0). Replace the generic “Gets
or sets” descriptions with meaningful documentation; apply the same
documentation improvement to the corresponding option properties in this cohort,
including num lm layers, mlp dim, imu timesteps, and qformer hidden dim.
In `@src/NeuralNetworks/Options/AudioVisualEventLocalizationOptions.cs`:
- Around line 30-31: Update the AudioVisualEventLocalizationNetwork constructor
and InitializeLayers flow to use the stored AudioVisualEventLocalizationOptions
as the single source for model configuration, including EmbeddingDimension and
NumEncoderLayers, instead of separate scalar parameters. Call
_options.Validate() during construction before initializing layers, or remove
the redundant options parameter if the scalar-parameter API is retained.
In `@src/NeuralNetworks/Options/Blip2Options.cs`:
- Around line 74-77: Update the ONNX options construction and Validate flow so
QformerHiddenDim, NumQformerLayers, NumHeads, NumQueryTokens, PatchSize,
VocabSize, VisionHiddenDim, LmHiddenDim, and NumLmDecoderLayers consistently
match the loaded graphs. Either reject conflicting caller-provided values or
expose the effective ONNX configuration, ensuring GetOptions(),
GetModelMetadata(), and NumQueryTokens report the same configuration.
In `@src/NeuralNetworks/Options/ClipOptions.cs`:
- Around line 25-30: Update ClipOptions so its inherited CLIP-specific
properties are not left as misleading unused defaults: either initialize
PatchSize, VocabSize, NumHeads, HiddenDim, NumEncoderLayers, VisionHiddenDim,
and NumVisionLayers with the supported variant’s values, or remove them from
this options path. Preserve the properties actually consumed by
ClipNeuralNetwork: EmbeddingDimension, MaxSequenceLength, and ImageSize.
In `@src/NeuralNetworks/Options/FinchOptions.cs`:
- Line 18: Update the FinchOptions constructor assignment for LearningRate to
use the documented default value 3e-4, preserving consistency with the property
initializer and XML documentation.
- Around line 111-114: Change the parameterless Validate() methods to internal
in FinchOptions (src/NeuralNetworks/Options/FinchOptions.cs:111-114), GLAOptions
(src/NeuralNetworks/Options/GLAOptions.cs:73-76), GatedDeltaNetOptions
(src/NeuralNetworks/Options/GatedDeltaNetOptions.cs:73-76), GriffinOptions
(src/NeuralNetworks/Options/GriffinOptions.cs:77-79), HawkOptions
(src/NeuralNetworks/Options/HawkOptions.cs:77-79), and RecurrentGemmaOptions
(src/NeuralNetworks/Options/RecurrentGemmaOptions.cs:103-105). Keep each options
type public and leave validation behavior unchanged.
In `@src/NeuralNetworks/Options/FlamingoOptions.cs`:
- Line 72: Set the default value of FlamingoOptions.PatchSize to 14, and update
both FlamingoNeuralNetwork constructor paths to assign _patchSize from
_options.PatchSize instead of hardcoding 14, so InitializeNativeLayers uses the
configured patch size.
In `@src/NeuralNetworks/Options/GanOptions.cs`:
- Around line 84-86: Update ValidateCore in GanOptions to validate both
GeneratorChannels and DiscriminatorChannels as required positive architecture
dimensions, alongside the existing LatentSize, ImageChannels, and
InitialLearningRate checks, before model construction.
In `@src/NeuralNetworks/Options/GLAOptions.cs`:
- Around line 73-76: The Validate methods in GLAOptions and GatedDeltaNetOptions
must validate LearningRate after ValidateCore; add the existing Require
validation using LearningRate and nameof(LearningRate) at
src/NeuralNetworks/Options/GLAOptions.cs lines 73-76 and
src/NeuralNetworks/Options/GatedDeltaNetOptions.cs lines 73-76, rejecting zero,
negative, NaN, and infinity values.
In `@src/NeuralNetworks/Options/Gpt4VisionOptions.cs`:
- Line 28: Replace the Gpt4VisionOptions initialization of VisionEmbeddingDim
with the inherited VisionHiddenDim property set to 1024, and remove the
redundant VisionEmbeddingDim declaration. Update both Gpt4VisionNeuralNetwork
reads to use _options.VisionHiddenDim, preserving the existing vision-width
behavior.
In `@src/NeuralNetworks/Options/RWKV7Options.cs`:
- Around line 42-45: Update RWKV7Options.Validate to validate FfnMultiplier
using the existing double-value Require overload, matching
FalconMambaOptions.Validate, while preserving the current ValidateCore checks.
In `@src/NeuralNetworks/Options/SambaOptions.cs`:
- Around line 42-45: Update SequenceModelOptions.ValidateCore to accept a
requiresInterval gate defaulting to false and validate AttentionInterval when
enabled. In src/NeuralNetworks/Options/SambaOptions.cs lines 42-45,
src/NeuralNetworks/Options/Zamba2Options.cs lines 43-46, and
src/NeuralNetworks/Options/ZambaOptions.cs lines 42-45, pass requiresInterval:
true while preserving each existing requiresHeads and requiresState values; no
direct changes are needed for other option classes.
In `@src/NeuralNetworks/Options/VideoCLIPOptions.cs`:
- Around line 44-72: Replace the placeholder XML documentation for NumFrames,
FrameRate, TextHiddenDim, NumFrameEncoderLayers, NumTemporalLayers, and
NumTextLayers with user-facing descriptions that explain each setting’s purpose
and expected units or semantics, including that FrameRate is the video sampling
rate. Add the required For Beginners section to each property and use clear
wording without identifier restatements or placeholder terms.
In `@src/NeuralNetworks/Options/VisionLanguageModelOptions.cs`:
- Around line 107-113: Update ValidateCore in VisionLanguageModelOptions to
validate PatchSize alongside the existing required dimensions, ensuring zero or
unset values raise the established ArgumentException before patch-based
consumers such as Blip2NeuralNetwork perform division.
- Around line 107-113: Update ValidateCore in VisionLanguageModelOptions to
retain only checks universal to every model. Add model-specific validation in
AudioVisualCorrespondenceOptions (EmbeddingDimension and Channels),
AudioVisualEventLocalizationOptions (EmbeddingDimension and Channels), and
UnifiedMultimodalNetworkOptions (EmbeddingDimension, MaxSequenceLength, and
Channels); do not require ImageSize for the unified model. Ensure each
Validate() invokes only checks for properties its model consumes.
In `@src/NeuralNetworks/Options/XLSTMOptions.cs`:
- Around line 41-44: Update XLSTMOptions.Validate to validate LearningRate with
ModelHyperparameterOptions.Require, ensuring zero, negative, and non-finite
values are rejected while preserving the existing ValidateCore checks.
In `@src/NeuralNetworks/RWKV4LanguageModel.cs`:
- Line 115: Update the constructor XML documentation associated with the RWKV4
language model to remove the orphaned vocabSize, modelDimension, numLayers, and
maxSeqLength parameter tags, add a parameter entry for options before
lossFunction, and keep configuration guidance on RWKV4Options.
In `@src/NeuralNetworks/VideoCLIPNeuralNetwork.cs`:
- Around line 189-194: Update the ONNX constructor to initialize _patchSize,
_visionHiddenDim, _textHiddenDim, _numFrameEncoderLayers, _numTemporalLayers,
_numTextLayers, _numHeads, and _vocabularySize from the validated
VideoCLIPOptions values, matching the native constructor’s option-driven
behavior. Remove the corresponding hardcoded literals while preserving the
existing assignments for the other fields.
In `@src/NeuralNetworks/XLSTMLanguageModel.cs`:
- Line 81: Add Require(LearningRate, nameof(LearningRate)) to
XLSTMOptions.Validate() in src/NeuralNetworks/XLSTMLanguageModel.cs:81-81 and
FlamingoOptions.Validate() in
src/NeuralNetworks/FlamingoNeuralNetwork.cs:274-274, using the existing double
overload so both optimizer-bound learning rates reject NaN, infinity, and
non-positive values.
In `@src/NeuralNetworks/Zamba2LanguageModel.cs`:
- Line 92: Update Zamba2Options.Validate() to reject AttentionInterval values
less than or equal to zero, while preserving validation of the existing
Zamba2-specific options.
In
`@tests/AiDotNet.Tests/IntegrationTests/Configuration/OptionsSurfaceRatchetTests.cs`:
- Around line 149-151: Update ReportRemainingGaps to inject ITestOutputHelper,
write the grouped byType report to the test output, and replace the tautological
Count >= 0 assertion with a meaningful assertion that the reflection walk found
at least one model type. Add the Xunit.Abstractions import and preserve the
existing MeasureGaps grouping behavior.
- Around line 128-135: Enable SettingAnOptionsPropertyChangesTheModel by
removing its stale skip and replace the NotImplementedException with assertions
covering migrated model families: constructing with non-default options must
return those same values from GetOptions() and produce a layer stack different
from the default construction. Update the related phase wording to reflect the
already-migrated families.
- Around line 231-235: Update MeasureGaps to prefer the modelOptions candidate
when resolving the concrete options type, falling back to options only when
modelOptions is unavailable; continue including OnnxModelOptions. Rerun the
measurement and adjust Baseline if needed. Also implement meaningful
non-default-option assertions in SettingAnOptionsPropertyChangesTheModel and
remove its Skip marker.

The ratchet counts enum- and string-typed constructor parameters as
configuration, so the count could never reach its floor while the migration
moved only numeric scalars. Detection is syntactic, since the script does not
resolve types: a bare identifier type whose default reads `Type.Member` is an
enum, and `string`/`string?` with a literal default is a string. An interface
defaulting to null matches neither.
Also picks up VisionMambaModel (9 params), which sat in the sequence group but
was never run, and UnifiedMultimodalNetwork, which was silently NOT migrated in
phase 3 — see below.
A third defect in the migration script, and the reason it mattered:
the constructor-signature pattern captured its parameter list with `[\s\S]*?`.
When a model declares a parameterless constructor that chains with `: this(...)`
BEFORE the real one, the lazy match ran past it hunting for `: base`, swallowing
a whole constructor body. The replacement was then not found inside the narrower
region the script edits, so the migration did nothing while still reporting
success. A parameter list never contains braces, so the capture is now `[^{}]*?`.
That failure mode is worth noting against the ratchet itself: it counts a
parameter as covered when the Options class has a matching NAME, so
UnifiedMultimodalNetwork scored as migrated while its constructor still took all
three parameters. The behavioural assertion is what closes that hole.
The migration is also idempotent now — a default the options constructor already
assigns is not appended a second time — so it can be re-run to pick up parameter
kinds an earlier pass did not recognise.
Build green, ratchet 861.

The default AdamW ignored MusicFlamingoOptions.LearningRate (1e-4) and used the generic 0.01, so a two-step probe raised the loss on the 105M-parameter model. Training_ShouldReduceLoss and MoreData_ShouldNotDegrade failed identically on master; all MusicFlamingo tests now pass.

… marked Merging master left this branch uncompilable in two ways that produced no conflict markers, so neither was visible from the merge itself. 1. VisionLanguageModelOptions' vision-tower members were renamed on master (VisionHiddenDim -> VisionDim, NumVisionLayers -> VisionLayers). That file did not conflict, so git took master's version silently while this branch's derived classes, their consumers, the tests and two generator scaffolds kept the old names -- 60 compile errors. Master and the phase-3 PR (#2130) already use the new names; only this branch carried the older snapshot. Master's own contract test asserts the old members are gone (SharedOptionsDocumentationContractTests: Assert.Null(vision.GetProperty("VisionHiddenDim"))). Renamed only what resolves to VisionLanguageModelOptions: five derived options classes, their five consumers, the affected test initializers, and the Flamingo/LLaVA scaffolds in TestScaffoldGenerator. Left untouched: the private fields and the serialized metadata keys ("VisionHiddenDim" / "NumVisionLayers") that master still uses, the other 70 generator sites, and every src/VisionLanguage/** model whose options declare their own NumVisionLayers. 2. InverseProblemPINN and MultiScalePINN moved their collocation-point counts onto options objects, but three call sites still passed them as constructor arguments (CS1739). Moved them onto InverseProblemOptions<double> / MultiScalePINNOptions and added the missing using for the latter. Verified: 60 -> 21 -> 72 -> 3 -> 0 errors, non-incremental build.

FinchOptions has published LearningRate, MinLearningRate, Beta1, Beta2, WeightDecay and the clipping pair since the options-surface work, but FinchLanguageModel never overrode GetOrCreateBaseOptimizer, so training ran on AdamW's own defaults and every one of the six was inert. Three of them differ from those defaults, so the model was not training at the recipe it documents: 1e-3 instead of 3e-4, 0.999 instead of the paper's 0.99, and 0.01 instead of 0.001. The model even carries a comment saying the clip bound "now lives in FinchOptions where a caller can reach it" -- nothing read it. Adds the override and an optimizer constructor parameter, following the same shape the sibling recurrent models already use (Griffin, Hawk, GLA, GatedDeltaNet): the paper recipe is the default, and a caller can pass any gradient optimizer instead. MinLearningRate is wired as well, which those siblings have no equivalent of -- it is the floor of the paper's cosine decay. The reviewer also asked for Validate() to run before InitializeLayers(). That call is already there, on the line above. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Twenty-two files conflicted. Master had independently grown its own copy of most of the options-surface work, so nearly every conflict was add/add between two versions of the same file rather than two different changes. Taken from master, because they are decisions master made after this branch forked: Validate() widened from internal to public on the nine sequence options classes, DocumentNeuralNetworkOptions' copy constructor narrowed to protected, GanOptions' ValidateCore no longer requiring GeneratorChannels and DiscriminatorChannels, and both README files -- the options-contract one because its extra paragraph linked to .github/PR2130_ADDITIONAL_REVIEW_PROOF.md, which is untracked now, and the SequenceFixtureReview one because master replaced a one-off proof replay recipe with the instructions the tool actually needs. Taken from this branch, because master's copy is the earlier state of the same work: VisionLanguageModelOptions (rebased onto VisionLanguageInputOptions with the ValidationRequirements overload), the options-contract and SequenceFixtureReview project files, GeneratedSequenceFixtureContractTests, and the ratchet and contract tests -- which carry the phase-3 numbers, Baseline 861 against master's 977 and 18 sequence options types against 17. ModelHyperparameterOptions.MaxGradNorm is dropped, which is this branch's change and not a merge artifact. Master's copy of that property is read by nothing: the MaxGradNorm that models actually clip with is the protected field on NeuralNetworkBase, and GraFPrintOptions declares its own and derives from ModelOptions. The base-class remark requires every property here to be read by the model that owns it, so the alias goes, and the documentation test that asserts its absence comes with it.

TensorShape is not an IEnumerable<int> on the net471 build of
AiDotNet.Tensors, so Assert.Equal(new[] { 2, 4 }, features.Shape)

.Shape.ToArray() is the idiom the rest of the suite already uses and
asserts the same sequence equality.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick winBLOCKING:
InitializeLayersis now an empty body with a stale ONNX comment.This change removes ONNX execution from
FlamingoNeuralNetwork<T>. The only remaining constructor callsInitializeNativeLayers(_options.Channels)at Line 216 and never callsInitializeLayers. The override therefore keeps a body that does nothing and a comment that describes a mode that no longer exists.The risk is not cosmetic.
InitializeLayersis a base-class extension point. If any base path calls it — construction, clone, or deserialization — Flamingo silently ends with an unpopulated layer graph and every branch list stays unbound, instead of failing. Make the override build the native graph, or make it fail explicitly.🐛 Proposed fix

- flamingo options now reject an undefined language model backbone in Validate rather than letting it reach the tokenizer factory as a backbone with no case - gpt-4v and imagebind onnx metadata publish the canonical ModelType, TaskType, ParameterCount, Architecture, InputShape and OutputShape keys that BlipOnnxContractTests pins; ModelMetadata carries none of them as properties, so a snake_case spelling left consumers with nothing - the audio-visual scene classification arm now teaches two distinct scenes and asserts each label wins on its own example; training both labels on one example let a constant 0.5/0.5 satisfy the count, sum and range checks whether or not fusion reached the head - the observing optimizer re-snapshots the parameter after the test's own perturbation, so ParameterChanged reports whether base.Step moved anything instead of always reading true Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

- BlipOptions and LLaVAOptions gain the copy constructors every sibling options class has; each chains to VisionLanguageModelOptions(other) and copies its own properties (BLIP: NumDecoderLayers, MlpDim; LLaVA: NumLmLayers, LanguageModelBackbone, VisionEncoderType). - FlamingoNeuralNetwork.InitializeLayers was an empty body with a comment about an ONNX mode that no longer exists. It now builds the native graph, so a base path that re-initializes layers gets a bound model. InitializeNativeLayers clears Layers before rebuilding, so a second call cannot duplicate them. - AudioVisualCorrespondenceNetwork: the private ComputeContrastiveLoss had no caller; removed. - Mamba2Options defaults are now Mamba-2 130M, verified against primary sources rather than recalled: the state-spaces/mamba2-130m config (vocab_size 50277, d_model 768, n_layer 24) and the authors' Mamba2 layer defaults it does not override (d_state 128, headdim 64, expand 2 -> 24 heads). Was 256 wide, 4 layers, state 64, 8 heads. MaxSequenceLength stays 512 and is documented as a library bound: an SSM has no positional limit and the checkpoint declares none. The only default-dependent test, ShippedSequenceDefaults_RemainUnchanged, is updated; both places that construct Mamba2LanguageModel set every dimension explicitly, so no test's model grows. Already fixed on this branch before this commit, verified: every public property of VideoCLIPOptions and DocumentNeuralNetworkOptions is documented.

8 conflict hunks in 4 files, resolved after reading all three sides: - AudioVisualCorrespondence, Blip2, LLaVA optimizer constructions: this branch's options-driven body with master's PaperOptimizerFactory.CreateFor chain ahead of its fallback (the factory returns null when no recipe is declared). - Flamingo: this branch's side. Its ONNX constructor now refuses to run, so master's ONNX body cannot return. That constructor held the type's only factory call, so the native constructor's hand-built optimizer is now passed through PaperOptimizerFactory.VerifyHandBuilt - kept as built, checked against [PaperOptimizer], and what keeps the recipe wired (AIDN104). - AudioVisualCorrespondence docs: this branch's outputSize 2 (its output is correspondence logits); master's facade-based example, which #2088 made compile. AiDotNet builds with 0 errors. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

The doc-example gate failed on #2130 with CS1739: VisionMambaModel no longer has an imageHeight parameter - this branch moved its dimensions onto VisionMambaOptions. The example now sets ImageHeight, ImageWidth, PatchSize, ModelDimension and NumLayers on the options, with the same values. The type is fully qualified because a second VisionMambaOptions exists in AiDotNet.ComputerVision.Segmentation.Mamba, and the snippet harness imports both namespaces.

Two test failures on #2130, both behaviour the branch had already decided on: - SequenceValidationSurfaceTests: bb44595 made Validate() internal on the Finch, GLA, GatedDeltaNet, Griffin, Hawk and RecurrentGemma options and added this test to guard it. The master merge 2045562 put all six back to public. They are internal again, identical to bb44595. Every caller is in AiDotNetTests, which has InternalsVisibleTo, and AiDotNet.OptionsContractTests compiles these files into itself. - ClipNeuralNetworkTests (x3, *_PathValidationComesFirst): the ONNX constructor validated its options before checking that the model files exist, so a missing file was reported as an options error. Validate() now runs after the path checks and before any option is read - master's order. Not yet run locally: the test build was stopped for low memory.

6b1f3ca made the neural-network trunk carry trainable members as declared state so raw Tensor/Vector/Matrix fields survive a checkpoint. It applied that to every trainable member, including sub-models that are registered with RegisterParameterComponent. StableVideoSR's diffusion core was therefore restored twice, and its trained clone failed in the before-parameters pass with "SetParameterChunks chunk 0 length 16 does not match parameter length 1008". An IParameterSource<T> component is owned by the parameter registry, as on master; raw numeric fields are still declared. The new ownership contract test fails with the exclusion disabled and passes with it. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
Merge 2045562 reverted more of 6b1f3ca and 33ed850 than the six Validate methods restored in d32c5c2: - JambaOptions, Mamba2Options and XLSTMOptions exposed Validate publicly again; it is the assembly-internal constructor boundary. - DocumentNeuralNetworkOptions' copy constructor went back to protected, so concrete document options could not be copied through it. - GanOptions.ValidateCore stopped requiring GeneratorChannels and DiscriminatorChannels. Unit 13's options contract tests failed on each. They and the sequence, GAN and options-ratchet suites pass: 945 passed, 0 failed. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Two conflicts, both from #2132 (deferred ModelData) meeting this branch's edits to the same metadata initializer in CCDM and TSDiff. Kept this branch's AdditionalInfo (CCDM's sigma fields were replaced by NumSamples here, so master's SigmaMin/SigmaMax keys name fields that no longer exist) with master's ModelDataProvider. Also converted the two eager ModelData sites master still carries in the ONNX branches of BlipNeuralNetwork and VideoCLIPNeuralNetwork (added by #2130 alongside #2132), which EagerModelDataAssignmentGuardTests rejects. Verified: net10.0 test build succeeds; the guard, ModelMetadataLazyModelData, CCDM, TSDiff, Blip and VideoCLIP suites: 183 passed. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Before, requested vision widths8/16 still produced actual[4,1024]patch tensors; corrected tensors and materialized projection counts now match both requests.Still draft. The separate effective-ONNX graph configuration findings and actual audio/visual-correspondence execution/training defects remain under work. These results are not a full-matrix, ONNX execution, GPU-performance, or merge-readiness claim.
Preserved earlier description and proof history
Unused gradient-alias correction: a957775
Removed only the migration-added, unconsumed ModelHyperparameterOptions.MaxGradNorm and its copy assignment. The actual network clipping fields/algorithms, optimizer MaxGradientNorm/EnableGradientClipping and independent PPO/GraFPrint settings remain unchanged. Root also verified the removed base is absent from freshly fetched master3185b41f1e1cffb81d76130e319233153c984471; this is a pre-merge migration-surface correction.
Before: four positive controls pass, two alias/XML checks fail. After:395 scalar tests pass each net10.0/net8.0/net471,0 failures/skips, plus root-independent395-case net10.0 replay. The previous assertion promising behavior for the unused option is explicitly replaced, not silently waived. Exact proof and unchanged algorithm boundaries.
Separate ONNX/effective-configuration and GPT4 width issues remain open. Still draft.
Validation API follow-up: faed368
Six migration-added constructor validators are now internal, preserving public option types/properties/defaults and all validation behavior. Six new API controls failed before; all390 scalar tests pass on each net10.0/net8.0/net471, with a root-independent390-case net10.0 replay. Proof, commands and limits.
The Eagle rename suggestion is not applied: both public EagleOptions types already exist at merge-base2a53ff3d4e27845773b4c9ad0a52b81f089613f7; renaming either would introduce a source break rather than repair a new collision. Fully qualified names or using aliases remain the compatible choice.
Separate ONNX/effective configuration, GPT4 duplicate width and gradient alias findings remain open. Still draft.
Additional reviewed fixes: f5d4aec
Four more findings addressed: positive shared GAN channel validation, VideoCLIP units/actual behavior/default provenance, BLIP/CLIP constructor XML tags, and the named AVC/BLIP/BLIP2/LLaVA/ImageBind documentation cohort.
Proof: original34-case cohort:6 passed/28 failed; corrected complete scalar suite:384 passed,0 failed/skipped on net10.0/net8.0/net471. Root independently repeated384 net10.0 tests. Eight other production files are documentation-only; Roslyn confirms executable syntax unchanged. No production model currently derives from GanOptions, so the channel tests prove its public-base validation contract, not existing GAN model construction.
Exact changes, commands and limitations. Existing native/main binaries and their earlier proof were preserved, not rebuilt or relabeled as this new scalar evidence.
Still draft: the separate ONNX/API/architecture findings below remain open.
Review-fix checkpoint: native paths verified; PR remains draft
Pushed native options validation and constructor fixes, integrated the completed #2128 fixes, and replaced the skipped configuration placeholder with real model guards. The typed shared validation checks only dimensions a model consumes; native patch construction preserves supported floor cropping. VisionMamba no longer requires unused text fields, and Flamingo honors native patch size and requires a usable multimodal gate count.
Actual local proof
Before/after results, immutable assembly hashes, reproduction commands and exact review disposition.
The earlier empty TRX and disk-interrupted build were excluded and replaced by fresh retained results. This proof does not establish ONNX graph/configuration equivalence or GPU performance.
Still open — not merge-ready
ONNX effective configuration and graph compatibility; inherited no-op options and phase-3 copy/ownership semantics; correspondence topology; remaining API/documentation and gradient-limit policy findings. Only fully addressed review threads are closed. Broader partial findings remain open and this PR remains draft.
Original PR narrative (historical scope; current proof and remaining gaps are above)
Phase 3 of #2090. Follows #2128 (phase 2). Spec in #2122.
Ratchet: 977 → 875. Eleven multimodal models now take their configuration through
VisionLanguageModelOptions: CLIP, BLIP, BLIP-2, Flamingo, LLaVA, ImageBind, GPT-4 Vision, VideoCLIP, UnifiedMultimodal, and the two AudioVisual networks. 102 parameters moved, carried over unchanged.Three defects in my own tooling, all caught by the build
The migration handled only one constructor per model. Eight of these eleven declare two, and both contain
_options = options ?? new XOptions(), so the script took the first and left the second's parameters untouched — 44 params moved instead of 102. It now migrates every constructor that takes an options parameter, with the options class carrying the union of their defaults.Repointing a guard at
_optionscould place it above the assignment — a null dereference. This appeared in three unrelated guard shapes (RWKV7's divisibility check in phase 2, Blip2's here, Flamingo's range check). Rather than teach the script to recognise each shape, the options assignment is now hoisted to the top of the constructor body, so every repointed reference is necessarily below it.Call sites got the options object as the last positional argument, but the new signature places
optionsbefore the optional collaborators. Now emitted as a named argument, so its position stops mattering.Two things worth knowing about the tree
private conston the model, invisible from the options file. They are resolved to their literal value with the constant's name kept as a comment:EmbeddingDimension = 512; // DEFAULT_EMBEDDING_DIM.AudioVisualEventLocalizationNetworkdefaults two parameters toVGGishAudioEmbedding<T>.Paper*. An open generic cannot travel to a non-generic options class; the script reports rather than emits, and the reference is closed over<double>(the constant is identical for everyT).Known gap, stated rather than hidden
Enum- and string-typed parameters are not moved yet —
VideoCLIP.TemporalAggregation,LLaVA.LanguageModelBackbone,LLaVA.VisionEncoderType. The ratchet counts them, so they cannot be forgotten; they are covered in a follow-up.Verification
