/model <name> on provider A, where the name is only known to provider B
(static catalog or OpenRouter), switched the session to B even when B had
no key: an immediate 401 for most vendors, and for OpenRouter — whose
runtime resolves with an EMPTY key instead of raising — a silent switch
onto a metered aggregator. The dashboard's flat Model field had two more
copies of the same guess ("vendor/model on a native provider" → openrouter).
detect_provider_for_model() now walks its ladder as candidates and skips any
target without credentials (env/.env key, auth-store login, or a usable
credential pool entry). Exceptions: the user NAMED the provider (/model nous)
or there is no current provider yet ("auto") — then the guess is handed back
so the credential step fails loudly instead of silently ignoring input. A
vendor/ prefix naming a provider declared in `providers:` is a selection, not
a guess, and always routes. The dashboard fallbacks apply the same gate.
Tests that pinned "switch to OpenRouter/vendor with no key" now grant the
credential they assumed; two new invariants cover the gate.
An aux task pinned to a private endpoint via `base_url` (a home Ollama
box at `byron.local`, a LAN IP, localhost) is the intended per-task
endpoint feature and can never bill a provider. The Settings → Model
banner still counted it as "still run on openai" forever and offered
"Reset all to main", which would wipe the working local setup; the
post-switch `stale_aux` report had the same blind spot; and the aux row
never showed the `base_url` the backend already sends, so the pin was
indistinguishable from a paid-provider pin.
- `GET /api/model/auxiliary` now stamps each task with `local_endpoint`,
the verdict of the one canonical classifier
(`agent/model_metadata.py::is_local_endpoint`) — no TS mirror of the
private-range rules, so frontend and runtime cannot drift.
- Desktop: the persistent banner filter is the pure
`staleAuxAssignments()` and skips `local_endpoint` pins; the pinned row
appends ` · <base_url>` when one is set.
- `_stale_aux_pins` (post-switch report) skips local pins the same way.
- `is_local_endpoint`: `*.local` (RFC 6762 mDNS) now counts as local, and
IPv6 literals no longer ride the "no dots ⇒ unqualified host" rule, so
a global-scope address (`2607:f8b0::1`) is not local while `::1`,
ULA and link-local still are via the `ipaddress` scope checks.
Slim redo of #106236 (@webtecnica) and #106234 (@huklaa), which fixed the
same symptom with a client-side classifier copy; the bug class, row
display and mDNS/IPv6 classifier corrections are theirs.

No runtime consumer read the proxy (terminal_tool/environments call is_interrupted()/set_interrupt()
directly); its only users were tests patching tools.interrupt._interrupt_event, which had no effect on
the code under test. tools/terminal_tool.py's own re-export of the name is owned by another worker.
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
