Closes#1538, #1539. Two related dropdown-staleness bugs reported by Deor
(Discord, May 03 2026).
#1538 — Nous Portal picker showed only 4 hardcoded models
=========================================================
The Settings → Default Model picker, the composer model dropdown, the
/model slash command, and the Settings → Providers card all showed only
four Nous models (Claude Opus 4.6, Claude Sonnet 4.6, GPT-5.4 Mini, Gemini
3.1 Pro Preview) because `_PROVIDER_MODELS["nous"]` had four hardcoded
entries and `_build_available_models_uncached()` fell through to the
generic `pid in _PROVIDER_MODELS` branch.
The actual Nous Portal catalog has 30 models live — Claude Opus 4.7, GPT-5.5,
Kimi K2.6, MiniMax M2.7, Gemini 3.1 Pro/Flash, several Xiaomi/Tencent/StepFun
entries, and more.
Fix:
- New `_format_nous_label()` helper in `api/config.py` — reuses the
`_format_ollama_label()` token rules, drops the vendor namespace, and
appends ` (via Nous)` so labels disambiguate from same-named direct-
provider entries (e.g. "Claude Opus 4.7" via direct Anthropic).
- New `elif pid == "nous":` branch in `_build_available_models_uncached()`
mirroring the Ollama Cloud pattern: live-fetch through
`hermes_cli.models.provider_model_ids("nous")`, prefix every id with
`@nous:` (matches the existing routing convention from PR-era #854 and
pinned in tests/test_nous_portal_routing.py), fall back to the curated
4-entry static list when hermes_cli is unavailable.
- Same fix applied to `api/providers.py:get_providers()` — that's the
separate code path that builds Settings → Providers card models, and
it had the identical bug shape.
#1539 — Removed provider lingered in dropdowns until restart
============================================================
After Settings → Providers → Remove, the provider's models still appeared
in every model dropdown until the page was reloaded. The server-side
TTL cache was correctly flushed (`set_provider_key()` calls
`invalidate_models_cache()` on both add and remove) but JS-side caches
were never dropped:
- `_slashModelCache` / `_slashModelCachePromise` (commands.js) — feeds
the `/model` slash-command suggestions.
- `_dynamicModelLabels` / `window._configuredModelBadges` (ui.js) —
populated by `populateModelDropdown()` on app boot and profile switch.
Pre-fix, `_removeProviderKey()` only called `loadProvidersPanel()`
which refreshed the providers card list but never asked any consumer
to re-fetch /api/models.
Fix:
- `static/commands.js`: new `_invalidateSlashModelCache()` helper that
nulls both cache slots, exposed on `window` (typeof-guarded so the
module remains importable in headless vm contexts — needed by the
existing tests/test_cli_only_slash_commands.py harness).
- `static/panels.js`: new `_refreshModelDropdownsAfterProviderChange()`
helper that calls the invalidator + `populateModelDropdown()`, wrapped
in try/catch so the providers panel update never breaks if a
downstream module hasn't loaded yet. Both `_saveProviderKey` and
`_removeProviderKey` invoke it (defense-in-depth: same staleness shape
applies to the add path too).
Tests
-----
- `tests/test_issue1538_nous_live_catalog.py` (12 tests): live-fetch
surfaces ≥20 entries, every id starts with `@nous:`, every label ends
with ` (via Nous)`, recent flagships (Opus 4.7, GPT-5.5, Kimi K2.6,
Gemini 3.1 Pro, MiniMax M2.7) reach the dropdown, static fallback
works when hermes_cli raises, label formatter unit tests (vendor
namespace stripping, variant rendering, MiniMax mixed-case), the
curated static list and its routing invariants are preserved.
- `tests/test_issue1539_provider_removal_dropdown_invalidation.py`
(11 tests): invalidator helper exists and clears both cache slots,
exposed on window with typeof guard, both save and remove paths
invoke the dropdown flush, helper calls both invalidator and
populateModelDropdown, helper is resilient to missing modules,
helper does not block panel refresh, server-side
`set_provider_key → invalidate_models_cache` invariant pinned.
Verified live on port 8789: `/api/models` Nous group returns 30
models (was 4); browser `document.getElementById('modelSelect')`
exposes 30 options under the "Nous Portal" group; the dropdown-flush
helper is callable from the browser and round-trip rebuild keeps the
dropdown at 30 options.
