Numeric Metadata Correction Checklist

Specs and existing handwritten inspection entries were updated together where those entries exist. Spec-backed inspection continues using spec metadata. Useful local descriptions and additional options are retained; no new runtime spec reads were introduced.

Numeric min/max boundaries are retained for discovery. Descriptions state whether each endpoint is included: > 0 excludes zero, (0, 2) excludes both endpoints, and (0, 1] includes only the upper endpoint. Conditional descriptions identify the mode in which a stricter bound applies; zero-valid greedy, disabled, and whole-file behavior is preserved.

The current CLI metadata and spec conversion only carry inclusive scalar bounds. Those fields alone therefore do not encode the complete acceptance predicate: clients must not treat a displayed minimum of 0 as a promise that zero is accepted in every mode. Runtime checks remain authoritative. No positive type, exclusive-bound fields, arbitrary epsilon, or conditional schema extension was added. Integer bounds were corrected directly.

Scalar Boundary Clarifications

Scope is request unless marked session. > 0 below means finite and positive where the consumer uses the positive-finite parser. Grouped options share the stated issue, not necessarily their defaults or upper bounds.

Done	Model / option	Previous metadata / spec	Runtime consumer / actual constraint	Fix
[x]	Qwen3 TTS repetition_penalty	Minimum 0 (spec)	Must be positive (session).	Retained minimum 0 as a boundary; explicitly described > 0 (zero excluded), with default unchanged.

[x]	LiveAvatar shift	Minimum 0 (spec)	Must be positive (pipeline state).	Retained minimum 0; documented shift > 0.

[x]	MiDashengLM min_stop_step	Minimum 0 (spec)	Positive integer parser (session).	Changed integer minimum to 1.

Session Allocation Bounds

All entries below previously advertised minimum 0 but use parse_size_mb_option, which rejects nonpositive sizes (shared parser). Names omit their canonical session family prefix for readability.

Done	Model	Options	Spec	Consumer	Fix
[x]	Audio8 TTS	ar_graph_arena_mb, ar_weight_context_mb, codec_graph_arena_mb, codec_weight_context_mb	spec	session	Changed integer minimum to 1 MiB for every listed option; retained defaults.
[x]	Fish Audio	ar_graph_arena_mb, ar_weight_context_mb, codec_graph_arena_mb, codec_weight_context_mb	spec	session	Changed integer minimum to 1 MiB for every listed option; retained defaults.
[x]	Higgs Audio STT	audio_encoder_graph_arena_mb, text_decoder_prefill_graph_arena_mb, text_decoder_decode_graph_arena_mb, text_decoder_weight_context_mb	spec	session	Changed integer minimum to 1 MiB for every listed option; retained defaults.

Sentinels And Coupled Constraints

The first three rows are direct advertised-behavior mismatches. Remaining rows are missing conditional, divisibility, or cross-option constraints, not evidence that every advertised scalar zero is invalid.

Done	Model / option	Previous metadata / spec	Actual consumer behavior	Fix
[x]	F5-TTS session frame_budget	Default/minimum 0; zero described as 2048 (spec)	Explicit values must be in [256,8192]; explicit zero throws (session).	Set minimum 256, maximum 8192, and effective default 2048; documented that explicit zero is rejected. Internal omitted-value sentinel unchanged.
[x]	AudioSR seed	-1 described as random (spec)	Every negative value maps to fixed seed 42; zero is an ordinary seed (pipeline).	Removed the false random claim and minimum -1; documented that all negative inputs and omission use fixed seed 42. Zero remains an ordinary seed.
[x]	MiDashengLM seed	-1 described as random, minimum -1, maximum 2147483647 (spec)	Unsigned 32-bit parsing rejects -1; omitted seed is 0 (session).	Set range [0,4294967295]; retained default 0 and documented fixed unsigned seed semantics. Downstream seed is uint32_t, widened to uint64_t for flow sampling.
[x]	LiveAvatar height, width, num_frames	Independent minimum values (spec)	Dimensions must be multiples of 16; blockwise frame count must be a multiple of 4 (pipeline state).	Documented multiples of 16 for dimensions and the multiple-of-4 frame constraint only for blockwise generation.
[x]	LiveAvatar vae_decoder_tile_size	Minimum 0, zero disables tiling (spec)	Enabled tiles must be multiples of 8 and larger than overlap (VAE).	Documented enabled tiles as multiples of 8 greater than the 64-pixel overlap; retained zero-disable.
[x]	MMS forced aligner session emission_window_sec, emission_context_sec	Missing upper/alignment constraints (spec)	Window positive, context nonnegative, both at most 3600 s; rounded 16 kHz sample counts must be divisible by 320 (emissions).	Added maximum 3600 for both; documented rounded 16 kHz sample counts divisible by 320, preserving context zero and the context/window relation.
[x]	TFGridNet audio_chunk_duration_sec, audio_chunk_overlap_sec	Independent nonnegative bounds (spec)	Enabled chunk length must exceed n_fft/2 samples; overlap must be positive and smaller than the chunk (session).	Retained numeric bounds; documented nonnegativity, sample-based chunk/overlap constraints, and strictly positive overlap only when chunking. Whole-file duration zero retained.
[x]	Apollo audio_chunk_duration_sec, audio_chunk_overlap_sec	Independent nonnegative bounds; prose already states the half-chunk overlap limit (spec)	Enabled chunk length must exceed n_fft/2 samples; overlap may not exceed half the chunk (session).	Added the enabled chunk's sample-based minimum; retained existing half-chunk overlap prose and zero behavior.
[x]	RE-USE audio_chunk_duration_sec, audio_chunk_overlap_sec	Independent nonnegative bounds; prose already states overlap must be shorter (spec)	Enabled chunk length must exceed sample_rate/50 samples; overlap smaller than chunk (session).	Added the enabled chunk's sample-based minimum; retained existing overlap relation and zero behavior.
[x]	MossFormer2 audio_chunk_duration_sec, audio_chunk_overlap_sec	Independent nonnegative bounds (spec)	When chunking is enabled, overlap must be smaller than duration (session).	Documented overlap smaller than duration when chunking; retained whole-file duration zero.
[x]	AudioSR chunk duration/overlap	Independent bounds (spec)	Overlap must be smaller than duration, including after sample rounding (pipeline).	Documented overlap smaller than duration, including after sample rounding.
[x]	Stable Audio Foundation init_noise_level	[0,1] (spec)	With init audio and k-diffusion, this becomes sampler_sigma_max, which must be positive (assignment, check).	Documented the Foundation/init-audio/k-diffusion positivity condition; retained [0,1] for the shared option.

Seed semantics remain model-specific. F5-TTS's default and the AudioSR/MiDashengLM seed descriptions now reflect existing behavior; no new zero-default or random sentinel was implemented. Any future runtime semantics change needs separate authorization and validation; the equivalence results below do not cover it.

Usage Documentation

• Updated the usage tables for all 33 families in this numeric checklist, including shared TTS, music, and speech analysis guides: positive/exclusive bounds, conditional constraints, allocation minima, seed behavior, and the F5 frame-budget default.
• Added missing Audio8/Fish allocation controls, MOSS-TTSD sampling controls, and LiveAvatar shift. Corrected Music3 CFG semantics, Seed-VC V2's duration no-op, and the general seed guidance.

Remaining Discovery Corrections

Done	Model / control	Fix
[x]	Echo-TTS text chunk size	Added canonical text_chunk_size to the spec with minimum 1 and default 300, allowing it through request-key validation to the existing consumer. Added a contract regression check and usage documentation.
[x]	MMS forced aligner audio chunking	Removed standalone audio-chunk flags from this model's alignment help; other alignment families retain their existing help.
[x]	MOSS-TTS-v1.5 / VoiceGenerator generation bounds	Added min_frames and max_frames to specs, local CLI tables, and usage docs. Documented automatic nonpositive values and the runtime-adjusted ceiling.
[x]	MiniMax-H3 cache window	Advertised 10%/95% progress controls; removed false literal sigma defaults and documented paired sigma overrides. Updated usage docs.
[x]	MOSS-TTS-v1.5 weight format	Corrected local help and the usage table to default native, preserving packaged quantization.
[x]	VoxCPM1 automatic retries	Removed the unconditional metadata default; documented true offline, false streaming, and streaming's warning/ignore behavior for explicit true.
[x]	Music3 ensemble takes	Added maximum 16 to local CLI metadata and documented the inclusive 1-16 range.

Runtime Validation Checklist

Checked rows state either a runtime option-equivalence pass or an exemption. Existing GGUFs are used where available; supported safetensors and external-spec packages are labeled explicitly. Unchecked rows retain missing coverage. Output quality is separate from this refactor check: a pass means old/new names reach the same consumers and behave consistently, not that generation quality or pre-existing model behavior is correct.

Instruction naming correction: instruct is canonical. The instruction-only runtime changes to Audio Flamingo, AuK, Maya1, MOSS-Transcribe-Diarize, and SAMSONE were reverted to main; their earlier alias runs below describe the superseded implementation. Newly added instruct aliases for BreezeTTS, CosyVoice3, FireRed Audio, FireRedTTS3, and Irodori require fresh runtime validation; earlier checks do not establish coverage for this correction.

Done	Model	Runtime validation requirement
[x]	ACE-Step	CUDA Turbo Q8: all three old/new aliases produce identical 12-second WAVs under existing embedded/current specs. Thinking invokes planner code generation, guidance enables CFG, and disabling either changes output; duration yields 60 planner codes and 12 seconds.
[x]	Audio Flamingo	CUDA Flamingo 3 Q4_K: both instruction names produce identical summaries under embedded and updated specs; the default produces a transcription instead.
[x]	AuK	Flash Q8 aliases match byte-for-byte across old/current external specs; editing rejects both correctly. Unexpected opening phrase is recorded separately as an output-quality observation, not an alias failure.
[x]	Canary ASR	CUDA Q8: legacy pnc and canonical punc produce identical transcripts with the existing embedded spec and the updated spec. Disabling the control removes punctuation/capitalization; the default restores them.
[x]	Chatterbox	Clone flow aliases/greedy override match byte-for-byte across specs. VC aliases match at the same request position with reversed-order controls. Truncation and repeatability observations are separate from option equivalence.
[x]	Chatterbox Turbo	CUDA Q8: token-limit aliases produce identical complete speech under existing and updated specs. Reducing the cap from 512 to 64 shortens output from 6.00 to 2.68 s.
[x]	Cohere ASR	CUDA Q8: both punctuation aliases produce identical text with embedded and updated specs; the default restores punctuation/capitalization.
[x]	ControlFoley	CUDA existing Q8 GGUF, eight-second upstream skateboarding video: legacy video/canonical video_file produce identical WAVs under embedded/current specs. Video decoding and all visual conditioners execute; output differs from text-only control.
[x]	CosyVoice3	CUDA Q8: legacy conv_weight_type=f16 remains accepted and produces the same WAV as omitting it, under existing and updated specs. ASR recovers the complete requested text.
[x]	DotTTS	Edit Q8: old/new instructions perform the requested word replacement with existing/current specs. Reversed-order control gives exact waveform matches at the same request position. Streaming reaches the expected offline-only edit rejection. Repeatability caveat recorded.
[x]	F5-TTS	Not required: duplicate guidance discovery removed; parser unchanged.
[x]	FireRed Audio	CUDA Q8: ASR token aliases match under embedded/current specs and a four-token control truncates identically. Generation text/audio aliases produce identical complete speech. Removed helper-arena setting remains an accepted no-op.
[x]	Fish Audio	Not required: token-limit help only.
[x]	FunASR Nano	CUDA Q8: both duration spellings produce identical transcripts and two audio chunks with a three-second setting, under embedded and updated specs.
[x]	GigaAM	CUDA multilingual F16 GGUF: bare/prefixed VAD paths produce identical transcripts and two VAD-derived segment boundaries under existing and updated specs.
[x]	GLM-TTS	Valid Flow/HiFT noise files: old/new aliases produce identical full-sentence WAVs with the old embedded spec and current override. ASR recovers the full text; controls reach their consumers.
[x]	Hviske ASR	CUDA Q8, 16-second Danish sample: both punctuation aliases produce identical text under embedded and updated specs; default conditioning restores capitalization.
[x]	Hviske v6	CUDA Q8, 16-second Danish sample: punctuated=false and punc=false, with cased=false, give identical text under embedded and updated specs. Enabling punctuation/casing changes formatting as expected.
[x]	Index Echo	CUDA 2B Q8: max_text_tokens=96 and max_tokens=96 give identical text/timestamps under existing and updated specs. An 8-token control truncates the cue and raises a malformed-subtitle error under both specs.
[x]	IndexTTS2.5	CUDA Q8: duration_factor=1.2 and duration_scale=1.2 match under existing and updated specs; output grows from 6.548 to 7.848 s. ASR recovers the complete requested text.
[x]	Inflect v2	CUDA original GGUF: speaking_rate=1.25 and speed=1.25 produce identical audio under existing and updated specs; 5.831 s versus default 6.492 s confirms the rate direction. ASR recovers the requested text.
[x]	Irodori TTS	Both alias pairs match byte-for-byte across old embedded/current specs; reference trimming and embedding loading execute. Embedding-conditioned extra tail is a separate output-quality observation.
[x]	Kokoro	CUDA Q8 offline: all three legacy/canonical arena names, with nondefault sizes, produce byte-identical WAVs under existing and updated specs. ASR recovers the requested text.
[x]	LFM2 Audio	CUDA upstream Q8 GGUFs require an explicit spec override (no embedded spec). With it, both chunk/one-pass aliases produce identical two-chunk transcripts; both enforce the limit and remain rejected on TTS/S2S where inapplicable.
[x]	LiveAvatar	Existing NVFP4/Q4/F16 package: all three image and memory-policy spellings produce byte-identical 45-frame videos. Nondefault false policy is logged in each run; sampled frames are valid and moving. Model-local parsing, not spec-backed validation.
[x]	Maya1	CUDA Q8: both instruction names produce byte-identical WAVs under embedded and updated specs; ASR recovers the requested sentence. Missing instruction still raises the required-input error.
[x]	MiniMax H3	CUDA existing Q4 component package: sampler=res_multistep and sampler_mode=res_multistep select the same nondefault sampler and produce identical 8.7-second audio. Canonical run also uses current spec override. GGUF has no embedded spec; no embedded-spec coverage claimed.
[x]	MiniMax Music3	Existing Q4/Q8/Q4 package: old/new 48 MiB arena names produce identical 20-second WAVs and logged allocations. Lyrics mismatch is recorded separately. Spec overrides do not control this model-local loader.
[x]	MiraTTS	Native safetensors: bare/prefixed nondefault weights produce identical WAVs and buffers; canonical names also work with the pre-refactor external spec. Omitted defaults match explicit native/native/F32. No legacy-GGUF coverage claimed. Existing session.wall_ms logging gap recorded.
[x]	MioTTS	Not required: request-option help names only.
[x]	MOSS-Transcribe-Diarize	Instruction aliases match in offline and streaming with existing/current specs. Custom prompt omits timestamps under both names; default prompt produces a parsed speaker turn.
[ ]	MOSS-TTS v1.5	Matching local package not located, nor found in audio-cpp's HF repositories. Configured package is third-party; not downloaded. Available MOSS-TTS-Local-v1.5 is a different family, not a substitute.
[x]	MOSS-TTSD	Instruction and text-temperature aliases produce byte-identical short dialogue across embedded/current specs; ASR recovers both sentences.
[x]	MOSS-VoiceGen	Instruction and text-temperature aliases produce byte-identical speech across embedded/current specs; ASR recovers the complete input.
[ ]	OuteTTS	Aligner-path aliases and file resolution remain unvalidated. No local package or audio-cpp-hosted package located; configured third-party package not downloaded.
[x]	OWSM	CUDA Q8: beam_size=2 and num_beams=2 produce identical transcripts offline and streaming, under embedded and updated specs.
[x]	PocketTTS	CUDA English Q8: token/frame limits, voice-state export/import, and five nondefault graph-arena aliases match exactly within offline/streaming modes. Offline old/new options also match across embedded/current specs. Two text chunks; an eight-frame control caps output at 0.64 s. ASR recovers both sentences with minor word differences.
[x]	Qwen3 ASR	CUDA 0.6B Q8: both VAD-path names load Silero and produce identical two-chunk transcripts under existing and updated specs.
[x]	Qwen3 TTS	CUDA CustomVoice Q8: speaker=ryan and voice_id=ryan override structured Aiden, matching the Ryan-only control and differing from Aiden. Offline results match across specs; streaming alias WAVs also match. Both modes transcribe to the requested text.
[x]	RVC	Existing F16 GGUF: valid pitch contour and real FAISS index, retrieval blend 0.25. Old/new names match exactly with packaged loading/current spec; pitch/retrieval consumers execute and ASR preserves the full source sentence.
[x]	SAM Audio	CUDA Small F32, six-second official office excerpt: image/video aliases produce byte-identical target and residual WAVs under old embedded/current specs. Vision executes and differs from text-only conditioning.
[x]	SAMSONE	CUDA Q8: old/new instruction names give identical audio descriptions under embedded and updated specs; the default prompt produces a different description.
[x]	sanoTTS	CUDA F32 Nano and PiperLite: legacy speaking_rate=0.8 equals speed=1.25, byte-for-byte under existing and updated specs. Both shorten audio versus default and preserve the full transcript.
[x]	Seed-VC	V1/V2 aliases match at corresponding request positions across packaged/current specs and reversed alias order. Noise files reach their reader; V1 duration control works. V2 parses both duration names but retains the pre-existing no-op; metadata correction is separate from alias equivalence.
[x]	Silero VAD	CUDA bundled safetensors (no model spec/GGUF fixture): both maximum-duration names at 2 s produce identical three-segment boundaries; default produces two segments.
[x]	Soprano TTS	CUDA Q8: bare/prefixed weight and chunk settings produce byte-identical audio offline and streaming with embedded and updated specs. Nondefault F16 backbone/decoder settings change their weight buffers; chunk size 80 splits the input, unlike the default.
[x]	Sopro TTS	CUDA F16: all three duration/reference aliases produce identical offline WAVs under existing and updated specs. Legacy-existing versus canonical-updated streaming WAVs also match, emit 11 chunks, and transcribe to the requested text.
[ ]	Stable Audio	Shared Small-SFX parser passes old/new sampler aliases with packaged/current specs; Euler matches exactly and PingPong changes output. Foundation parser remains untested: no local checkpoint or audio-cpp-hosted Foundation package located.
[x]	Supertonic	Not required: duplicate speed help removed; parser unchanged.
[x]	Vevo2	Six arena aliases and reference/prosody-duration aliases match exactly on Q8 with packaged loading/current override. Prosody explicitly enabled; 9/6 s controls produce 9.04/6.08 s, and ASR recovers the full text.
[x]	VibeASR	CPU upstream two-GGUF package: old/new token limits match using pre-refactor/current external specs. Full transcript at 96 tokens; four-token control truncates. No embedded-spec coverage claimed.
[x]	VieNeu v3 Turbo	Existing Q8 GGUF: dictionary, frame-cap, and minimum-chunk aliases give identical 5.2-second WAVs under packaged/current specs. Real SEA-G2P library/dictionary executes. Nondefault cap=false and minimum=60 reach the existing consumers; no frame-ceiling boundary claim.
[x]	VoxCPM1	CUDA Q8: all seven arena aliases at nondefault sizes match byte-for-byte under existing/current specs. Reference encoding is exercised; ASR recovers the full input.
[x]	VoxCPM2	CUDA Q8: all seven arena aliases at nondefault sizes match byte-for-byte under existing/current specs. Reference encoding is exercised; ASR recovers the full input. Chunk-strategy help is documentation-only.
[x]	Voxtral Realtime	Not required: token-limit help only.
[ ]	ZipVoice	Language and timestep-shift aliases remain unvalidated. No local package or audio-cpp-hosted package located; configured third-party package not downloaded.
