fix(catalog): ingest llama.cpp multimodal and dual-envelope metadata - #1807
Merged
Conversation
…1797) Closes the two halves #1799 deliberately deferred. 1. `multimodal` is now recognized as an image signal. llama.cpp and Ollama-compatible servers emit it instead of `vision`/`image-input`, so a server that truthfully advertised image support still produced an image-blind row. Mapped to the closed text|image enum rather than passed through: an out-of-enum modality makes Codex reject the whole catalog file. 2. A `data[]` row is enriched from a sibling `models[]` entry for the same id. llama.cpp splits one model's metadata across both arrays - capabilities in `models[]`, `meta` in `data[]` - so the two halves never met. The conservative boundary that refuses a stray `models` key is preserved deliberately, because that refusal exists for a reason: - membership is decided entirely by `data[]`; a sibling-only entry is dropped - matching is exact id equality (id, or Ollama's model/name), never fuzzy - an id claimed twice in the sibling array is skipped rather than guessed - only keys ABSENT from the `data[]` row are filled, so `data[]` always wins - the sibling array is bounded by the same limit as the primary envelope Verified against the verbatim payload from the reporting server: contextWindow 262144 and inputModalities ["text","image"], where before it was context-only. The characterization test that pinned the gap is flipped, and three guards pin the boundary: data[] wins a conflict, sibling-only rows stay ignored, ambiguous ids are skipped.
Review found the first attempt unsound in a way that crossed a real safety
boundary. mergeSiblingModelMetadata ran BEFORE providerModelMatchesDiscoveryFilter
and copied every absent key, so a models[] entry could supply the exact field a
provider filter required. Reproduced against the real Chutes policy:
withoutSibling -> items: []
withSibling -> items: [{id:not-proven-tool-capable, supported_features:[tools]}]
That contradicts the claimed membership boundary and affects every filtered
provider, not just llama.cpp.
Two corrections:
- Enrichment now runs AFTER admission, on already-published rows only, so it can
change what is KNOWN about a model but never WHICH models are published.
- Only capability keys are copied (capabilities, features, supported_features,
modalities, input_modalities) instead of every absent key.
Verified: the reproduction now yields [], #1797 still resolves 262144 and
[text,image], and a non-whitelisted sibling key is ignored.
Ordering already prevents a sibling from flipping an admission verdict, but supported_features and features are exactly the two keys real provider filters test (registry.ts:1591 requires supported_features to contain "tools"; registry.ts:1883 tests features.tool_use). A key that is both enrichable and filter-relevant is one refactor away from becoming a bypass again, and #1797 does not need either. Enrichable set is now capabilities, modalities, input_modalities.
The header still described the image half as unfixed and claimed a merged item would stay image-unknown, contradicting the end-to-end assertion below it.

Require one unambiguous raw sibling identifier before enrichment.
Line 376 indexes every id, model, and name value as an independent identity. A sibling such as { id: "model-a", name: "model-b", capabilities: ["multimodal"] } can therefore enrich data[] row "model-b", although the sibling ID is "model-a".
Line 446 also looks up finalId after stripIdPrefix processing. A raw data[] ID of "prefix/model-a" can therefore match a sibling raw ID of "model-a". This violates the required exact same-ID boundary and can publish incorrect capability metadata for an admitted model.
Collect the non-empty sibling identity fields first. Skip the sibling when they disagree. Match enrichment against the original data[] ID, not finalId. Add regression tests for conflicting sibling aliases and prefix-stripped IDs.

Remove the duplicate items declarations.
Each listed test callback declares const items twice in the same lexical scope. Bun will reject the file with a block-scoped redeclaration error before it evaluates these regression cases.
Keep one declaration at each location. The declarations in different test() callbacks can keep the same name.
Also applies to: 101-101, 110-110, 127-127, 139-139

Summary
Closes #1797 — the two halves #1799 deliberately deferred.
A llama.cpp server splits one model's metadata across two arrays: an Ollama-style
models[]carryingcapabilities, and an OpenAI-styledata[]carryingmeta. Discovery reads onlydata[](deliberately — a straymodelskey must not be trusted as a source of models), so the served context and the image signal never met. A server that truthfully advertised multimodality still produced a context-unknown, image-blind row.Two changes:
multimodalis recognized as an image signal. llama.cpp and Ollama-compatible servers emit it instead ofvision/image-input. It is mapped to the closedtext|imageenum rather than passed through, because an out-of-enum modality makes Codex reject the entire catalog file.An admitted
data[]row is enriched from a same-id siblingmodels[]entry.The conservative boundary that refuses a stray
modelskey is preserved, and review hardened it twice:data[]row, before any enrichment. The first attempt merged first, which let a sibling supply the exact field a provider filter required — reproduced against the real Chutes policy, where a row lackingsupported_features: ["tools"]was admitted once a same-id sibling provided it. Enrichment may change what is known about a model, never which models are published.capabilities,modalities,input_modalitiesare copied.supported_featuresandfeaturesare deliberately excluded despite being capability-shaped: they are the two keys real filters test (registry.ts:1591, :1883). Ordering already prevents a bypass, but a key that is both enrichable and filter-relevant is one refactor away from becoming one, and llama.cpp: multimodal capability and dual-envelope /v1/models metadata are not ingested #1797 does not need them.data[]; a sibling-only entry is dropped. Matching is exact id equality (id, or Ollama'smodel/name), never fuzzy. An id claimed twice in the sibling array is skipped rather than guessed. The sibling array is bounded by the same limit as the primary envelope.Verification
End to end on the verbatim payload from the reporting server:
Independent audit (gpt-5.6-sol explorer) returned FAIL on the first attempt for the admission bypass, then PASS after the fix. It re-ran its own Chutes reproduction and attacked every allowlisted key:
Prototype pollution, non-object siblings, oversized/deeply-nested siblings, cross-key id collisions, and hostile modality injection were all probed and produced no further defect. Raw modality tokens cannot leak:
provider-fetch.tsfilters totext|image|audio, mapsmultimodal, andcatalog/parsing.tsfilters again before serialization.Commands, run on an isolated Linux checkout at the exact head:
bun x tsc --noEmit— exit 0bun run test tests/catalog-llamacpp-capabilities.test.ts tests/routing-capability-catalog.test.ts tests/core-lab-boundary.test.ts— 32 pass / 0 failBoth new admission-boundary regressions fail without the source change (activation exit 1).
The test that previously characterized this gap is flipped, and three guards pin the boundary:
data[]wins a conflict, sibling-only rows stay ignored, ambiguous ids are skipped.Checklist
