Both servers expose OpenAI-compatible /v1/chat/completions and /v1/models,
so we route them through pi-ai's `openai-completions` API the same way
Fireworks does — but with a per-installation base URL the user enters
during onboarding instead of a hardcoded one. The shared schemas grow a
`local` credential payload carrying just the baseUrl; the credential
resolver surfaces it on `ResolvedCredential.baseUrl`, the runtime bridge
forwards it through `prepareRun`, and the worker plumbs it into
`resolveModel` so the streamed Model<openai-completions> targets the
user's server. The local-cost path short-circuits to zero in cost-writer
since users bill their own hardware, and the live model list is fetched
from the saved baseUrl by `fetchLocalConnectorModels` (Ollama and LM
Studio both speak the standard OpenAI catalog shape). Onboarding ships
a new LocalProviderCard and the Settings panel a LocalForm; both default
to the catalog's per-connector localhost URL and accept any custom URL.
Each of these catches already logged via an accessible `logger` or `log`.
The migration wraps the thrown value through `classifyUnknownError(raw,
fallback)` and emits the log line with the structured `[code]` prefix.
Observable behaviour — return values, fail strings, DB writes — is
unchanged; the only addition is a machine-readable `code` on every log
line so future telemetry can bucket by category.

src/main/ipc-credentials-handlers.ts (4) save, remove, test lookup, test resolve
src/main/hire-hook.ts (3) getAgent, connector def, outer exception

src/main/ipc-support.ts (2) ipc handler throw, emitEvent send
Why only 20 tonight: 248 catches exist in src/main/. Rewriting them all
in one commit is high-diff-risk (collides with Linus's in-flight
database/backup/migration work on database/*, connector-definitions-*,
message-* and scripts/*) and low-value (pure-library catches with no
accessible logger produce dead `void classified` constructs). The
taxonomy module is committed separately so the remaining 228 sites can
land incrementally via the C6.2 proposal.
All 11 files selected sit outside Linus's working set. Verified:
- pnpm typecheck clean
- pnpm test:unit 498 passed
- oauth-login-service.start: require definition.auth to be present and
oauth kind before dispatching; captures oauthId in a local so the rest
of the flow does not re-assert the nullable chain
- ipc-credentials-handlers save: reject connectors without an auth
schema instead of crashing on property access
- ipc-credentials-handlers test: require provider and defaultModel to be
set before calling into pi-ai, returning a diagnostic result otherwise
Two tightly-coupled hardening changes to the credential IPC module.
(1) Drop the self-built `DesktopOk/DesktopErr/ok/err/handle` helpers
that called `ipcMain.handle` directly, bypassing the trusted-renderer
check in `ipc-support.registerHandle` and the `ZodError ->
IPC_INVALID_PAYLOAD` sanitizer. The module now takes `registerHandle`
and `fail` as deps (wired from `createIpcSupport`) and imports `ok`
from `ipc-core-common`, mirroring the OAuth handler layout.
(2) Tighten `redactSecrets` to issuer-prefixed patterns only (Bearer,
`sk-`, `sk-ant-`, `sk-proj-`, AKIA access key IDs, three-segment JWTs).
The previous blanket `[A-Fa-f0-9]{40,}` and `[A-Za-z0-9+/]{48,}={0,2}`
rules were shredding legitimate diagnostic text — git SHAs, UUIDs,
Fireworks model identifiers like `accounts/fireworks/models/...`, and
any long opaque ID — into `[REDACTED-HEX]` / `[REDACTED-B64]`, which
made provider errors unreadable in the renderer.
Pi-ai's `streamSimple`/`SimpleStreamOptions` has no per-request env
escape hatch; its Azure/AWS/GCP ADC providers read `process.env`
directly. The previous implementation wrote `extraEnv` into
`process.env` globally and relied on a `finally` after
`stream.result()` to clean up, so two concurrent `testCredential`
calls would clobber each other's env, expose the wrong credential
to in-flight streams, and on error paths fail to restore
previously-set values.
Wrap the env-mutating branch in a module-level promise chain so at
most one `extraEnv` test runs at a time, snapshot the prior value
of every key we overwrite, and restore (or delete when unset) in
`finally`. Tests that resolve to `extraEnv: undefined` bypass the
mutex entirely.
