Summary

Mobile items 1-3 of the 30 September product backlog.

  • Remote authentication ([Bug] API Key missing from background model discovery/capabilities requests breaks tool support on llama.cpp #696, LM Studio 401 report): the saved key now reaches startup discovery, the model-selection capability refresh, server-list checks and every capability probe (llama.cpp /props, Ollama /api/show, LM Studio /api/v1/models and its thinking probe), through the existing HTTPS-only header policy with redirects refused. A 401/403 is reported as an authentication error instead of an empty model list, a model with no tools, or a healthy health page. Authenticated /props requests skip the shared per-endpoint cache. A keyed private HTTP address says keys are only sent over HTTPS (policy unchanged).
  • /v1 address (separate defect found while tracing [Bug] API Key missing from background model discovery/capabilities requests breaks tool support on llama.cpp #696): the connection check requested /v1/v1/models and probes requested /v1/props, so capability detection fell back to name guessing and tool support disappeared. Both now use the address without its trailing /v1; proxy prefixes stay.
  • Image delete: remote-generated .jpg / .webp images can be deleted (delete only accepted <id>.png).
  • Web search: a refused or rate-limited search page reports a tool error instead of "No results found".

Type of Change

  • Bug fix (non-breaking change that fixes an issue)

Screenshots / Screen Recordings

No UI layout change.

Checklist

General

  • I have performed a self-review of my code
  • I have added/updated comments where the logic isn't self-evident

Testing

  • I have tested on Android
  • I have tested on iOS
  • Existing tests pass locally (npm test) - running in CI
  • I have added tests that prove my fix is effective or my feature works

Security

  • No secrets, API keys, or credentials are included in the code
  • Keys stay in Keychain and are only sent over HTTPS

Related Issues

Relates to #696. The SM-X800 delete report and the web-search report are not reproduced; these are the defects found on the shared paths.

Additional Notes

#696's exact setup (key on private HTTP) still won't send the key under the current HTTPS-only policy; it now says so. Device checks on iOS and Android are still needed.

Summary by CodeRabbit

  • Bug Fixes
    • Remote server connection tests and model discovery now use saved API keys, including checks when opening the server screen.
    • Authentication failures are reported clearly during connection checks and model discovery. HTTP 401 and 403 responses no longer trigger alternate endpoint checks.
    • Endpoint checks avoid duplicating /v1 in server addresses.
    • Deleting generated images now supports PNG, JPG, JPEG, and WebP files.
    • Web search now reports unsuccessful HTTP responses instead of treating them as search results.

…check (item 1)

- Startup discovery and the capability refresh on model selection read the
  saved key from Keychain (after the existing migration) and pass it on.
- llama.cpp /props, Ollama /api/show, LM Studio /api/v1/models and the LM
  Studio thinking probe send the key through the existing HTTPS-only header
  policy and refuse redirects.
- A 401/403 is an authentication failure: model-list requests throw it, the
  connection check returns it before any health-page fallback, and a refused
  probe is not read as proof the model lacks a feature. Discovery failure
  keeps the last known models.
- Authenticated /props requests bypass the per-endpoint in-flight cache, so
  servers with different keys never share a result.
- A keyed private HTTP server reports that keys are only sent over HTTPS.

Discovery passes the saved key to every capability probe and throws an
authentication error on a 401/403 model-list response instead of returning no
models. The connection check returns the refusal before falling back to a
health page, and a keyed private HTTP address reports that keys are only sent
over HTTPS.

…ths (item 1)

Separate defect found while tracing #696. The connection check requested
/v1/v1/models for an address ending in /v1, got a 404 and fell back to a health
page; the capability probes requested /v1/props and /v1/api/show, got 404s and
fell back to name guessing, which hid tool support. The check now uses the
same /v1 rule the model-list request already used, and the probes run from the
address without its trailing /v1. Proxy prefixes are kept.

…tem 1)

Opening the server list and the per-row check called the store directly
without the key, so an authenticated server read as offline. Both now go
through the manager's connection check, which reads the key from Keychain.

Claude-Session: https://claude.ai/code/session_01NLGbSsujqjtnxBLLcnb9Ph
Remote generation saves <id>.jpg or <id>.webp when the server returns those
formats, but delete only accepted <id>.png and the native store only removes
.png, so those images could never be deleted from the gallery. Delete now
accepts the image's own file in generated_images with any of the formats it
can be saved as; non-PNG files are removed after the same owned-path checks.

The SM-X800 report has not been reproduced; this is the deletion defect found
on the shared path.

… (item 2)

The web search tool read the body of any response, so a rate-limited or
refused search page parsed to zero results and the model was told nothing
exists for the query. A non-OK response is now a tool error with its status.

The 30 September report has not been reproduced; markup changes on the search
page are still unchecked.

📝 Walkthrough

Walkthrough

Remote server checks and model discovery now pass saved API keys and handle authentication refusals. Generated-image deletion supports additional image formats. Web search handling rejects HTTP responses with status 400 or higher. Generation integration tests use a shared network stub and longer timeouts.

Changes

Remote server authentication and discovery

Layer / File(s) Summary
Keyed endpoint checks
src/services/remoteTransportPolicy.ts, src/services/httpClientUtils.ts
A shared policy identifies HTTP endpoints with API keys. Endpoint tests avoid duplicating /v1 and return immediately for HTTP 401 or 403 responses.
Credential-aware capability probes
src/stores/remoteModelCapabilities.ts, src/services/remoteServerManagerUtils.ts
Capability probes accept API keys, apply authorization and redirect policies, and propagate authentication errors. Keyed probes bypass endpoint-only in-flight sharing. Provider initialization and capability rediscovery pass keys read from Keychain.
Server model discovery and checks
src/stores/remoteServerHelpers.ts, src/services/remoteServerManager.ts, src/screens/RemoteServersScreen.tsx
Server discovery passes saved keys to capability probes and propagates authentication refusals. Connection checks mark the server unhealthy when key retrieval fails. The screen uses remoteServerManager.testConnection for automatic and manual checks.

Generated-image deletion

Layer / File(s) Summary
Supported image paths and deletion
src/services/localDreamGenerator.ts
Deletion accepts matching PNG, JPG, JPEG, and WebP paths. Non-PNG files are unlinked without calling the native store; PNG files continue through it.

Web search response handling

Layer / File(s) Summary
Web search response status check
src/services/tools/handlers.ts
The search handler throws an error containing the HTTP status when the response status is 400 or higher, before parsing its body.

Generation integration test timing

Layer / File(s) Summary
Remote model failure test setup
__tests__/integration/generation/remoteModelFailureCopy.rendered.integration.test.tsx
Both tests use a shared rejected fetch stub, 8-second render waits, and 30-second test timeouts.
Remote reasoning render waits
__tests__/integration/generation/remoteReasoningDropped.rendered.redflow.test.tsx
The test uses 20-second render waits and a 60-second test timeout.

Security Architecture Review

Security architecture risk: 🔵 Low · up to e7576

Keys remain restricted to HTTPS, and authentication refusals are handled more clearly. One credential-boundary question remains: automatic discovery can send a saved key outside a configured proxy prefix, and the intended recipient of that fallback request is not established.

Retained concerns

  • Low · security · inferred: Newly credentialed startup and capability-selection discovery inherit a fallback that sends the saved key to origin-root /api/tags rather than beneath the configured proxy prefix. The fallback was already credentialed for existing callers, but these callers previously supplied no key. If the root route belongs to a different service or tenant, the new automatic path could expose that credential. The routing contract remains unresolved; this is not a verified disclosure.
Security review details

Security Blast Radius

  • inferred — The unresolved credential exposure is scoped to saved keys for affected prefixed HTTPS endpoints. A root handler on a shared origin could receive each such key when ordinary discovery failure reaches the fallback; startup iterates configured servers. Any gained authority would be limited by those keys' remote permissions, which are not supplied. No cross-tenant recipient or downstream privilege use has been demonstrated.

Security Findings and Attack Paths

  • inferred — The conditional attack path requires a configured prefixed HTTPS endpoint, a non-authentication failure or unusable response from its model-list route, and an origin-root /api/tags recipient outside the intended credential audience. Source establishes the request construction and new automatic credential supply, but not the final recipient. The supplied candidate remains deferred rather than verified.

Trust Boundaries and Controls

  • observed — Bearer keys are withheld from HTTP endpoints, public HTTP endpoints fail validation, and discovery and probe requests specify redirect refusal. Listing 401/403 responses terminate discovery before fallback. These controls constrain transport exposure but do not establish whether two paths on the same HTTPS origin share a credential audience.

Resilience and Maintainability Implications

  • observed — A failed rediscovery can leave prior capabilities applied to the selected provider, as in the base. Those records supply feature flags; provider creation separately obtains the server's saved key and applies the transport policy. Stale capabilities therefore do not themselves demonstrate possession of another credential or bypass of remote authentication.

Hardening Proposals

  • proposed — Define one explicit credential-audience contract for listing and capability routes. Preserve the configured proxy prefix by default; allow a credentialed origin-root fallback only when that route is explicitly part of the same authorized service.

…failure (item 1)

A 401/403 from /v1/chat/completions during the thinking probe read as "this
model does not think". It now propagates as an authentication error like the
other probes; other failed probes still read as no thinking.

Discovery on a private-LAN HTTP address with a saved key keeps working without
the key, as before (a paired Desktop can be saved that way). Only when such a
server refuses the request does the check say keys are only sent over HTTPS.

Both timed out in CI (41-minute Jest step) while passing on the same commit earlier and in
under 2 s locally. The failure-copy suite now answers 'unreachable' at the Desktop HTTP
boundary from the start of each test, so no real LAN address is ever dialled, and both
suites give their rendered waits headroom for a slow runner. Assertions are unchanged.

/v1/models (Ollama format) and /api/tags built the same RemoteModel fields with the same
keyed capability probe. Both now call mapOllamaModels; each keeps its own model filter, and
key handling, errors, fallback order and the OpenAI/OpenRouter mapping are unchanged.
