The bare-tail tie-break ranked candidates by prompt price alone, so two
entries sharing a tail where one is cheaper on prompt but far dearer on
completion could resolve to the entry that undercharges output-heavy
traffic — contradicting the "highest-priced wins for money safety" promise.
Rank by the combined prompt + completion per-token cost instead, so the
choice stays deterministic and money-safe whichever way traffic leans. As
before there are zero bare-tail collisions in the live feed, so this changes
no resolved price today; it only governs the latent case.

The generic provider treated any Venice-style model_spec.pricing as
authoritative after only a None check, so a native both-zero price served
the model free, a negative one credited the caller on every request, and a
non-numeric string threw while parsing — the outer catch then dropped the
provider's entire catalog.
Coerce both native prices through the resolver's _as_float and reject
absent / non-numeric / negative / both-zero values, falling through to the
shared litellm→OpenRouter→fail-closed chain instead. This extends the same
money-safety guard the litellm and OpenRouter rungs already apply to the
native source, and keeps one malformed entry from emptying the catalog.

The generic provider computed modality as "text->text" for any vision model
and "text" otherwise, discarding the source's own modality and mislabelling
image-capable models. Carry OpenRouter's modality string through verbatim, and
when a source doesn't supply one, derive it from the captured input/output
modalities in the same "in->out" shape (e.g. "text+image->text").

When a bare model id matched several OpenRouter entries by tail, the first feed
entry won, making the resolved price depend on feed order and risking an
undercharge if a cheaper reseller happened to sort first. Pick the
highest-priced candidate instead: deterministic and money-safe, since
undercharging is the hazard. An exact id match still wins ahead of any tail
match. Measured against the live feed there are zero bare-tail collisions
today, so this only governs the latent case.

litellm's max_tokens is the completion cap (it equals max_output_tokens for
~94% of models), not the context window, so falling back to it overstated the
context as the output limit. Take context from max_input_tokens alone; a model
that reports none falls through to the id-based estimate downstream, which is
honest about being a guess rather than mislabelling the output cap.

A litellm cost entry that lists a model but prices both tokens at 0 (free
moderation/rerank tiers) was resolved as a real price, importing the model
enabled and served for free. Reject a both-zero (or negative) litellm hit so
the caller falls through to the next source or fails closed, mirroring the
_has_valid_pricing check the OpenRouter feed already applies.

A generic (OpenAI-compatible) upstream whose /models response omits pricing
was silently defaulting to $0.001/M tokens and a 4096 context window. For a
provider like DeepSeek that reports no price, this undercharged real usage by
~280x — a direct money leak — while presenting a plausible-looking price.
Resolve each model through trust-ordered sources instead: the provider's
native schema (Venice's model_spec) first, then litellm's bundled cost map
(curated list prices), then the OpenRouter feed. Capture the richer metadata
those sources carry (cache rates, modalities, max output tokens, context)
rather than only price and context. When no source knows the model, import it
disabled with a warning rather than invent a number, so an operator can price
it before it serves traffic.
Context has no trustworthy source of last resort, but it is not a billing
input, so a model priced without a reported context window falls back to an
id-based estimate. The whole source-incomplete fallback (price chain +
context estimate) lives in one pricing_resolver module so it can later be
hoisted into the base provider unchanged.
