Every zed-hosted completion failed with
500 {"error":{"message":"[500]: An internal server error occurred."}}
for every model id, including deliberately invalid ones.
Root cause: ZED_PROVIDER held display-cased names ("Anthropic", "OpenAi",
"Google", "XAi"), and normalizeZedProvider's return value is serialized
straight into the `provider` field of the POST /completions envelope. Zed
matches that field exactly and fails the request before looking at the model,
which is why the model id never mattered.
Verified live against cloud.zed.dev with an otherwise identical request:
{"provider":"anthropic",...} -> 200
{"provider":"Anthropic",...} -> 500 {"message":"An internal server error occurred."}
{"provider":"open_ai",...} -> reaches the OpenAI request parser
{"provider":"openai",...} -> 500 (same internal error)
The spellings now follow Zed's own GET /models catalog, which reports
`anthropic`, `open_ai` and `google`. That also makes normalizeZedProvider
identity on catalog values instead of corrupting a value Zed just supplied —
previously it accepted the correct lowercase input and re-cased it into the
form that 500s.
`x_ai` follows the same underscore convention; this account's catalog exposes
no xAI models, so that one spelling is by convention rather than observation.
The constant is module-local and every branch compares against it, so internal
dispatch (initProviderState / convertProviderEvent / buildProviderRequest) is
unaffected. Two existing tests asserted the display-cased values and one passed
"Anthropic" to wrapZedCompletionStream directly; all are updated to the wire
values the executor now produces.

- Type 12 no-explicit-any errors in 3 new test files (real types, no masking):
chat-early-schema-validation-6412, models-catalog-envkey-6406, zed-provider.
- Suppress MitmProxyTab.tsx no-html-link-for-pages (false positive: the link is
an /api/settings/mitm cert download, an API route not a Next page).
- Allowlist tests/integration/v1-contracts-behavior.test.ts net -2 asserts: #6303
moved embedding/image shape coverage to models-catalog-route + specialty tests.
- Rebaseline cycle drift measured on the release tip (captain fixes are net-zero,
verified): cognitive 877->882, cyclomatic 2035->2050, file-size proxies/chat/
ApiManagerPageClient/ProxyRegistryManager + models-catalog-route testcap +5.
- Fix stale CLAUDE.md: no-explicit-any is error (not warn) in tests/ since #6218.
