Dotta 051b425fdf fix(evals): price explicit response model identities (#17808)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Product E2E operations reserve model cost before each provider
request.
> - Providers can return an exact snapshot name after a request selects
a model alias.
> - The estimator required the response name to equal the request alias.
It left valid snapshot usage unpriced and invalidated its reviewed
bound.
> - This pull request lets a versioned pricecard declare a small list of
exact response names that share its reviewed rates.
> - The benefit is correct cost coverage while request selection and
unknown-model handling stay strict.

## Linked Issues or Issue Description

Refs #17765 for the shared eval gateway request policy.

**What happened?**

An eval request can select `gpt-5.4-mini` and receive
`gpt-5.4-mini-2026-03-17`. Even with complete usage, the estimator
returns `null`. The gateway also rejects that response identity as
evidence for its reviewed reservation bound.

**Expected behavior**

A pricecard can name exact response identities with the same verified
rates. Unlisted snapshots stay unknown. A declared response identity
must not become an allowed request identity.

**Steps to reproduce**

1. Configure a route with an alias pricecard and an exact response
snapshot.
2. Return complete Responses usage for that snapshot through the
gateway.
3. Observe that the old estimator leaves the charge unknown and
invalidates the bound.

**Paperclip version or commit**

Reproduced in the shared estimator and gateway at
`507dc70be26c191e372f09e58dc0965e73bf8f57`.

**Deployment mode**

Other: the credential-free Product E2E operations harness. The same
library serves attached deployment targets.

## What Changed

- Add optional `responseModels` to versioned eval pricecards. Validate
one to sixteen unique exact additional identities.
- Reuse one response matcher in cost estimation, reviewed bound checks
and supported request-policy cache-write attribution. Cache attribution
also requires the reviewed provider and request identity to match. Keep
exact request-model admission unchanged.
- Admit the field in the strict operations manifest. Include it in the
existing whole-price bound digest.
- Cover fragmented JSON and SSE forwarding, persisted usage, durable
ledger replay, partial responses, unknown snapshots, invalid mappings,
stale bound evidence and unchanged request admission.
- Document mapping provenance, version changes and preservation of
historical ledgers.

## Verification

- Focused provider usage, gateway and operations tests: **185 passed,
zero skipped** on the cache attribution follow-up. The exact snapshot
assertions failed before the initial repair. Three positive cache-write
snapshot tests also failed before the follow-up and now pass.
- `pnpm test:e2e:runner:typecheck`: passed after building required
workspace declarations.
- `pnpm test:e2e:runner:unit`: 4,311 passed, two skipped and four
failures. The same four failures reproduce on unchanged base `507dc70`
(79 passed, four failed in the two affected files): two Daytona Copilot
image identity assertions and two Pi catalog/profile expectation
assertions. This PR does not change those files or their source inputs.
- `pnpm -r typecheck` and `pnpm build`: passed again on the exact cache
attribution follow-up commit.
- The private Cloud consumer passed 57 offline compatibility tests again
on this exact follow-up source. These cover the declared snapshot
estimate, exact request selection, unknown snapshot and incomplete usage
handling, ledger holds, and source export admission. No provider calls
were made.
- `git diff --check`: passed.
- `pnpm test:run`: interrupted after repeated embedded PostgreSQL
startup failures in existing native-session and other database suites.
The failed attempt is preserved and does not count as a full local suite
pass. Only this checkout's verified test process group was stopped; it
left no processes running. The first sandboxed workspace typecheck could
not open a local tsx IPC socket; the later authorized check passes. An
initial runner typecheck also lacked fresh-checkout workspace build
declarations; its later run passes.
- All forwarding tests use local synthetic response bytes. No provider
calls, releases, deployments or paid eval campaigns were run for this
repair.

## Risks

- An incorrect mapping can apply incorrect rates. The pricecard author
must verify provider provenance and change the price version. Validation
bounds the list and uses exact matching only.
- Existing pricecards remain exact-name only when the new field is
absent. Adding or changing a mapping invalidates old reviewed bound
evidence. Historical ledgers and receipts are not rewritten.

## Model Used

OpenAI Codex, GPT-6 family. The exact runtime deployment ID and context
window are not exposed in this session. The agent used reasoning, source
editing, terminal commands and credential-free tests. No model inference
was used by the eval harness for this repair.
