`BaseExecutor.buildHeaders(credentials, stream?, clientHeaders?, model?, health?)` was
shadowed in three executors by same-named helpers with unrelated signatures:
hailuo-web private buildHeaders(token: string, yy: string)
lmarena protected buildHeaders(_model: string, credentials: unknown, _body: unknown)
qwen-web private buildHeaders(token: string, cookieHeader: string, chatId?: string)
Name collisions, not overrides — each reported TS2416. They are renamed to
`buildStreamHeaders` / `buildRequestHeaders` / `buildApiHeaders`; the two lmarena test
files that called the helper directly are updated with them.
Worth stating precisely, because the shadow sat on a live dispatch path without being a
live bug: `BaseExecutor.countTokens()` calls `this.buildHeaders(credentials, false)`, and
all three inherit `countTokens()`. It is unreachable today only because
`buildCountTokensUrl()` returns null unless `config.format === "claude"` and the URL
carries `/messages` — hailuo-web and qwen-web set no format, lmarena sets `"openai"` — so
`countTokens()` returns at the guard above. Latent, not live; one `format` change away
from passing a credentials object where a token string is expected.
Two more, surfaced by clearing the above:
* `lmarena` declared `buildUrl` and `transformRequest` `protected` while both are public
on BaseExecutor (TS2415 — a subclass may widen visibility, never narrow it). Both were
masked behind the buildHeaders TS2416 and appeared one at a time as it cleared. Runtime
is unaffected; JavaScript has no member visibility.
* `GithubExecutor.refreshCredentials` had no declared return type, so TypeScript inferred
the union of its four literal returns. `GheCopilotExecutor` legitimately overrides it
with a wider `providerSpecificData` (it also records the enterprise proxy URL) and no
`expiresIn`, which is not assignable to that inferred union. Declared as
`RefreshedCopilotCredentials | null` — same shape of fix as #8489, on a different method.
Validation: full tsc error-set diff against the base config — 335 -> 331, zero new errors
(line-number-agnostic). `typecheck:core` clean; the 15 existing test files importing a
touched executor pass, including lmarena's 44 across the two updated files.
`plan3-p0.test.ts` fails identically with and without this change (it reads the
developer's real ~/.omniroute DB rather than a test-scoped DATA_DIR).
The new test pins that the inherited method is no longer shadowed — verified to fail on
the base, where all three prototypes still carry their own `buildHeaders` — and that the
`countTokens()` early return which kept it harmless still holds.
* fix(lmarena): modernize Arena web provider + static Direct-chat catalog
Update the lmarena provider for arena.ai (product rebranded from LMArena):
- Route chat via arena.ai create-evaluation with Chrome TLS impersonation
(tls-client-node) and optional browser-minted recaptchaV3Token.
- Seed Text+Search (48) into the chat registry; seed Image (27) only into
IMAGE_PROVIDERS. Disable live HTML model discovery; resolve public names to
Arena UUIDs from the static TypeScript allowlist (no scrape JSON in-repo).
- Soft-exclude 404/502 model ids; slow/stop bulk test-all probes for this provider.
- Do not fold IMAGE_PROVIDERS/video specialty into the chat provider catalog when
a chat registry already exists (lmarena/openai/xai).
- Display name Arena (Free); keep wire id `lmarena` / alias `lma` for back-compat.
- Theme-aware provider icons: arena-light.svg / arena-dark.svg.
- Preserve split Supabase SSR cookie reconstruction for arena-auth-prod-v1.*.
* fix(providers): align provider-models-route test fixture + regen provider reference
Fold the topaz image-only catalog entry's apiFormat/supportedEndpoints
into the local-catalog test fixture (route now tags media-only
providers per the lmarena PR's staticModels.ts change), regenerate
PROVIDER_REFERENCE.md against the merged release providers.ts, and add
the changelog fragment for #6280.
