Disable only Remend's incomplete-HTML stripping in message/tool content and reasoning rendering. Keep TeX, source data, and sanitization unchanged; unfinished HTML can display literally.
PR #266 identified the less-than comparison trigger. This uses an independently authored renderer configuration fix rather than its TeX-spacing workaround, with streaming, incremental, literal-code, and safety regressions.
A connect that fell back to typed model ids replaced the stored model list
with the typed ids alone, then pruned the user pins against it. A transient
/models failure (503, timeout) therefore deleted every discovered model, its
detected metadata, and its pins, and answered 200.
- DiscoverResult carries the endpoint's HTTP status. A 401/403 fails the
connect even when ids are typed: a rejected key is not a missing model list.
- A failed probe keeps the stored snapshot for the SAME base URL, so the
prune cannot delete pins for a probe that failed. A new base URL starts
clean, so an older endpoint's models never follow the URL.
- Comment corrections: the route contract and the CustomProviderSettings
fields described the behaviour from before the manual-ids change.
- tests/custom-provider-route.test.ts covers the four branches: transient
failure, rejected key, new endpoint with no model list, working probe.
tsc and eslint clean. Suite: 2554 tests, 2 failures, both also failing on
6959482 (render-sidebar date drift, subscription-auth install artifact).
Hosted OpenAI-compatible APIs often serve chat but not GET /models
(Volcengine Ark Agent Plan returns 404), so connect failed. Accept a
typed list of model IDs: merged into discovered models when /models
works, used alone when it does not. The typed list is stored as
customProvider.manualModels so reconnects and pin saves keep it.
A local endpoint that publishes no limits — LM Studio's /models says nothing —
left every model on the 8192/4096 defaults with no way to say "this one has a
131k window". Each discovered model now gets three optional pins in the
endpoint editor: context window, max output tokens, thinking (auto/on/off).
A pin always wins: user pin → what the endpoint published → compiled default.
Blank means no opinion, so discovery keeps ruling wherever you don't pin. Pins
live in customProvider.overrides keyed by model id, stored apart from the
discovery snapshot: a reconnect refreshes the models and prunes the pins of
models that vanished while keeping the rest.
Pins are written by PATCH /api/custom-provider, which never probes — the whole
point is configuring a server that isn't answering /models correctly. Connect
still probes and still fails loudly when the endpoint is down. A pin under 2048
tokens is rejected on the write side and clamped up on the read path, matching
the compaction-floor discipline.
Custom models were pinned reasoning:false, so every one of them offered a
single thinking level ("off") while built-in reasoning models offered the
standard ladder. The endpoint's /models metadata now decides:
- detectReasoning() trusts explicit metadata only — a boolean
reasoning / supports_reasoning / thinking, or a reasoning token in
supported_parameters (vLLM, OpenRouter), capabilities, tags or
architecture.output_modalities. No name guessing: a false positive would
send reasoning_effort to a server that rejects it.
- CustomModel carries the detected flag (persisted, sanitizer keeps it),
toPiModel passes it through, and pi-ai does the rest — default
off/minimal/low/medium/high set, reasoning_effort on the wire.
Verified in the browser against a local OpenAI-compatible mock: the
reasoning-capable model exposes off/minimal/low/medium/high, the plain one
stays at off, and a prompt with medium actually arrives as
reasoning_effort=medium.
The prior change made the vision slot show every model (image-capable first),
which relaxed the filter for built-in providers too — built-in text-only models
became selectable for Vision. Centralize the vision rule in ModelMenuList:
built-ins must report image input; custom-endpoint models stay selectable (their
capability may be unreported). Image-capable still float first.
Replace arbitrary event-loop budgets in two release-gate tests with fresh per-attempt sign-in notifications and the actual consent control reply, bounded by a clear watchdog. Retain all final-state assertions and explicitly verify successful connected/error-free completion.
Controlled token/save gates demonstrate both old 100-turn waits return before completion; the corrected waits remain pending and retain the final persistence/UI assertions after release. Add small watchdog result/error/timeout tests. No production, workflow or dependency changes.
Isolated checks: focused 87/87, full suite once 2517/2517, full ESLint and typecheck. The full run preceded three runtime-erased non-null array-index annotations; focused tests/typecheck/full ESLint passed again on final source.
Preserve original contributor commit 3bb28e5f29. Resolve only the settings-dialog conflict by retaining current General/update behavior: the donor General-only language placement is explicitly superseded by the human-approved row BELOW the full-width Deepgram key. The assigned implementation worker will implement that placement and approved shared dropdown finishing. Foundation only, not a checked candidate.
Adapt the bounded probe-completion foundation from PR #130 by aksalatdev (source commit 535202bebe038fa1e0648f5df809d5ccfc26d071), not its mixed stream-salvage implementation.
Require a non-failed call followed by a matching probe_done result with neither isError nor explicit details.ok:false. Preserve older clean acknowledgments, saved attempts, and all existing handoff/retry/provider policies. Share the native completion seam with phase detection and exclude explicit refusals from UI phases.
Verify retained failed-probe Retry recovery with real agent/tool composition and synthetic engines: one fresh conclusion, one handoff, then teacher selection, without stored-tool replay. Focused tests 58/58; full tests 2473/2473; typecheck and full ESLint pass in isolated storage with scrubbed provider credentials.
