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.

Pull the litellm model_cost lookup (both id spellings + case-insensitive
fallback) out of backfill_cache_pricing into a reusable litellm_cost_entry
helper. No behaviour change; the upstream price resolver reuses the same
lookup semantics.

A live upstream provider re-finds its own database row in two places —
PPQ.AI's insufficient-balance self-disable and the base
refresh_models_cache — with WHERE base_url == self.base_url AND
api_key == self.api_key. That uses a rotatable secret as a self-handle:
if the row's key rotates under a live object, it can no longer find
itself.
Carry the row's primary key on the instance as db_id, stamped centrally
by from_db_row via a _build_from_row construction hook that subclasses
override, and look the row up with session.get(UpstreamProviderRow,
db_id). This also closes a latent gap where providers built outside the
init path (auto-topup) never received db_id.

The ui/README.md was still stock create-next-app boilerplate. Replace it with the
real story: the UI is a Next.js static export served by FastAPI from ui_out/, the
two-process dev loop (backend :8000 + `make ui-dev` :3000 with hot reload, auto-
targeting :8000), the build/integration commands, and the cross-origin CORS note.
Also make the "ui_out not found" startup warning actionable — it now points to
`make ui-build` / `make ui-dev` instead of silently saying it skipped serving.

WHERE guard now matches on hashed_key, so the UPDATE always affects one
row and result.rowcount is always truthy. Remove the conditional and its
unreachable else branch.
11000 is nutshell's generic, unregistered TransactionError covering many
unrelated failures, so trusting the code alone made any 11000 retryable.
Gate the generic code on the 'not enough inputs' detail text; keep trusting
the registered 11005 (TransactionUnbalanced) on the code alone. Behavior is
unchanged for every existing case; a bare non-shortfall 11000 now surfaces
immediately instead of burning the retry budget.

The same-mint shortcut in swap_to_primary_mint did a same-mint
split(include_fees=True) — which burns the mint's NUT-02 per-proof input
fee — but returned the full token amount, over-crediting the user (the
same bug already fixed for the trusted-mint receive path). It also
skipped DLEQ verification that the trusted path performs.
Extract the shared same-mint redeem into _redeem_same_mint (load mint,
verify DLEQ, split, credit amount - input_fees) and delegate from both
recieve_token and the shortcut, so the two paths can't drift again. This
shortcut is reachable when PRIMARY_MINT_URL is set outside CASHU_MINTS.

The comment described "21 proofs @ 100 ppk" arithmetic, but the mocked
token has one proof and get_fees_for_proofs is hard-mocked to 3, so the
math wasn't exercised. Describe what the mock actually does.

recieve_token swaps the incoming proofs at the same mint with
include_fees=True (paying the mint's NUT-02 per-proof input fee) but credited
the full face value. On every topup from a fee-charging trusted mint, routstr
over-credited the user by the fee and its own wallet drifted toward insolvency.
Subtract get_fees_for_proofs(proofs) from the credited amount, mirroring the
foreign-mint swap path which already accounts for it. Adds a fee-charging
trusted-mint unit test (credited == face - input_fee).
