Per deep-review verdict SHIP-WITH-FIXES on PR #2636:
1. Profile-switch reconciliation: _refreshProfileSwitchBackground now re-fetches
/api/settings and re-applies hidden_tabs for the new profile. Without this,
Profile A's hidden-tabs choice stayed in effect under Profile B until the
user opened Settings → Appearance.
2. A11y: switched chips from role=button + aria-pressed to role=switch +
aria-checked. The pressed/not-pressed wording confused screen-reader users
because chip-off looks like the off state. Added role=group +
aria-labelledby on the container, and a :focus-visible style on the chips.
3. Server-side belt-and-suspenders: api/config.py now strips 'chat' and
'settings' from hidden_tabs at validation time, matching the client's apply-
time filter. A tampered POST can no longer persist the forbidden values.
3 new regression tests added (chat/settings rejection, profile-switch wiring,
chip a11y attributes).

Custom providers that have a curated models: list in config.yaml
(e.g. ZenMux gateways) should show ONLY those configured models in
the picker dropdown, not the full /v1/models catalog.
Before this fix, _named_custom_groups unconditionally called
_read_custom_endpoint_models() which would pull hundreds of models
from aggregator gateways and overwrite the user's curated list.
Now the build checks if the custom_provider entry has a non-empty
models dict/list in config.yaml — if so, it skips the live fetch
and uses only the configured models (same behavior as hermes-agent
model_switch.py Section 4 patch).
Closes: configure-model-list-should-be-authoritative
When an anonymous custom endpoint (bare base_url, not a named custom_providers[] entry) fails its /v1/models probe, the provider group was silently dropped from the model picker entirely. This made the endpoint unusable even when /v1/chat/completions would work fine.
The fix adds an elif branch: if pid == 'custom', a cfg_base_url is configured, but no models were returned by the probe, the group is still added with an empty model list. Users can then select the Custom group and type a model ID manually in the picker's free-form input.
Closes#2542.
Backend (api/config.py):
- resolve_model_provider(): check custom_providers for prefix match
BEFORE the config_base_url branch. Previously, providers with a
base_url set (e.g. deepseek) would catch all slash-delimited model
ids and return the config provider, preventing custom provider
routing.
- get_available_models(): include model aliases in response so the
frontend can resolve them on /model commands.
Frontend (static/commands.js):
- cmdModel(): resolve aliases by fetching /api/models before fuzzy
matching the dropdown.
- Add bare-model fallback when the alias resolves to a slash-delimited
provider/model id (e.g. "deepseek/deepseek-v4-flash").
- Add cross-provider fallback: when the model is from a custom provider
not in the active provider dropdown, call /api/session/update directly
with the provider/model id and provider override.
The get_available_models() function only handled dict-format models
(`{model_id: {}}`) for custom_providers entries, silently dropping
models specified as YAML lists (`[model1, model2]`) or list of dicts
(`[{id: ..., label: ...}]`).
This caused users who define their custom providers with list-format
model declarations to see zero or incomplete model entries in both
Settings → Preferences → Default Model dropdown and the chat
interface model picker.
The fix adds an `elif isinstance(_cp_models_dict, list)` branch with
support for three list sub-formats:
- Plain string list: `models: [m1, m2]`
- Dict list: `models: [{id: m1, label: ...}]`
- Mixed: `models: [m1, {id: m2}]`

Replace the earlier frontend-reset approach with a backend side-channel
approach that preserves the queue (event, data) tuple shape.
Problem (Opus catch):
- Live SSE frames emitted by _sse() in api/streaming.py:2296 carried no
'id:' field. Only journal-replay frames (via _sse_with_id) emitted IDs.
- Frontend's _lastRunJournalSeq cursor stayed at 0 during live streaming.
- Mid-stream error → reconnect-to-replay arrived with after_seq=0.
- Server replayed every journaled event from seq 1.
- assistantText (closure-scoped) had accumulated all live tokens already
→ double-rendered output.
Fix:
- api/config.py: STREAM_LAST_EVENT_ID: dict = {} module-level dict.
- api/streaming.py put(): capture journal event_id, write to
STREAM_LAST_EVENT_ID[stream_id]. Keep queue tuple as (event, data).
- api/routes.py _handle_sse_stream: read STREAM_LAST_EVENT_ID[stream_id]
at emit time, use _sse_with_id when set.
- api/streaming.py finally block: pop STREAM_LAST_EVENT_ID for cleanup.
Why side-channel instead of 3-tuple:
- Earlier attempt (queue tuple → (event, data, event_id)) broke 4 existing
tests: test_cancel_interrupt, test_sprint42, test_sprint51,
test_issue1857_usage_overwrite. These all unpack 'event, data = q.get()'.
- Frontend-reset approach (reset assistantText before replay) broke 3
other tests: test_smooth_text_fade, test_streaming_markdown,
test_streaming_race_fix. _wireSSE must NOT reset accumulators because
legacy reconnect doesn't replay events; only journal-replay does.
Side-channel preserves both invariants:
- Queue contract stays (event, data) — legacy consumers unbroken.
- Frontend accumulators stay alive on _wireSSE — legacy reconnect unbroken.
- Live SSE emits 'id:' so the journal cursor advances correctly.

fix(config): preserve nvidia/ prefix on NVIDIA NIM (closes#2177)
Self-built. nesquena APPROVED with extensive end-to-end trace including
cross-tool agent CLI verification and 12-shape behavioural harness.
Move the `_PORTAL_PROVIDERS` guard in `resolve_model_provider()` to run
BEFORE the `prefix == config_provider` strip branch. The guard was added
for NVIDIA (along with the Nous portal cases in #854 / #894) but was
placed after the strip, so it never fired when `config_provider == "nvidia"`
and the model id started with `nvidia/`.
For `model_id="nvidia/nemotron-3-super-120b-a12b"`,
`config_provider="nvidia"`:
- prefix = "nvidia", bare = "nemotron-3-super-120b-a12b"
- prefix == config_provider → True → strip branch returned bare name
- `_PORTAL_PROVIDERS` guard never reached
- bare "nemotron-3-super-120b-a12b" sent to NVIDIA NIM → HTTP 404
NIM requires the full namespaced path. The fix moves the portal guard
to run first, so all portal providers (Nous, OpenCode-Zen, OpenCode-Go,
NVIDIA NIM) always preserve the full `provider/model` id regardless of
whether the prefix happens to equal the provider name.
This also closes a latent symmetric bug for the Nous case if a
`nous/<model>` id ever existed in the catalog.
Test plan:
- New `tests/test_issue2177_nvidia_prefix_preservation.py` covers:
- nvidia/nemotron-... under nvidia (the reported case)
- cross-namespace qwen/ and meta/ under nvidia (regression pin)
- every static nvidia model in `_PROVIDER_MODELS` resolves to itself
- latent nous/<model> under nous (structural ordering pin)
- non-portal providers (anthropic) still strip — fix doesn't over-correct
- Existing portal-routing suites (test_nous_portal_routing.py,
test_issue895_894_nous_prefix.py) continue to pass.
- Full test suite: 5320 passed, 4 skipped, 3 xpassed.
Reported on Discord by @vishnu (Nathan forwarded as #2177).
When a provider's 'models' config contains dicts (e.g. {"id": "x", "label": "y"})
instead of plain strings, _apply_provider_prefix() crashes with:
AttributeError: 'dict' object has no attribute 'startswith'
This happens because the list comprehension at line 3505 passes the raw dict
as the model ID. The fix extracts 'id' and 'label' from dict entries while
keeping string entries as-is.
Fixes the /api/models and /api/onboarding/status 500 errors.
