Closes#1579.
api/updates.py was building the GitHub compare URL from local HEAD short SHA:
repoUrl + '/compare/' + curSha + '...' + newSha
where curSha = `git rev-parse --short HEAD`
Whenever local HEAD diverges from upstream — unpushed work, dirty stage
branches, forks, in-flight rebases, release-time merge commits whose SHA
only lives in the maintainer's local history — the compare URL points at
a SHA github.com has never seen and returns the standard 404 page.
Reporter (@ai-ag2026) observed:
https://github.com/nesquena/hermes-webui/compare/c660c7f...86cb22e
→ 404 because c660c7f was an unpushed local commit.
The right base is `git merge-base HEAD <compare_ref>` — the most recent
commit local and upstream share. Since `git fetch` succeeded just before,
the merge-base is guaranteed to exist on the upstream GitHub repo.
Behavior matrix:
Pure-behind clone (no local commits): merge-base == HEAD; URL unchanged.
Behind + local-only commits (#1579): merge-base != HEAD; URL points at
public ancestor instead of local HEAD.
merge-base failure (shallow clone): current_sha=None; JS link guard
suppresses link rather than emitting
a known-broken URL.
Also hardens static/ui.js: reset the link's href and display:none on every
banner render, so a stale link from a prior render can't survive a re-render
where the new payload has current_sha=null.
Tests:
- test_current_sha_is_merge_base_not_local_HEAD — reporter's scenario
- test_current_sha_equals_HEAD_when_no_local_commits — backward compat
- test_current_sha_falls_back_to_None_when_merge_base_fails — defensive
- test_whats_new_link_resets_display_and_href_on_every_render
- test_whats_new_link_suppressed_when_curSha_falsy
- test_reporter_url_shape_no_longer_produces_invalid_compare_url
4094 → 4100 passing. 0 regressions.
Three small follow-ups from the review:
1. Remove the over-broad except Exception around get_active_hermes_home()
in _handle_cron_run. The function is in-memory dict reads + one
Path.is_dir() stat — if it raises from inside a request handler,
api.profiles is in a state we shouldn't be making cron decisions in.
A silent fallback to _profile_home=None re-introduces the exact
bug #1573 fixes (worker thread runs unpinned against process-global
HERMES_HOME). Better to 500 the request than risk silent cross-
profile state corruption.
2. Add a thread-safety note on os.environ mutation in api/profiles.py
explaining why _cron_env_lock is sufficient — CPython env-var
assignment is GIL-protected at the bytecode level but the multi-step
read-modify-write pattern (snapshot prev → assign new → restore on
exit) is not atomic without explicit serialization. The lock makes
the entire context-manager body run-to-completion serially, including
any subprocess.Popen() calls inside run_job() that inherit the env.
3. New regression test (test_cron_run_does_not_silently_swallow_profile_resolution_errors)
pinning the no-silent-fallback contract via source-level assertion.
Catches future re-introduction of the over-broad except clause.

Reporter (Deor, Discord #report-bugs, May 03 2026 14:19 PT, relayed by
@AvidFuturist) saw the Settings → Default Model dropdown rendering the
OpenCode Go provider as TWO separate optgroups: "OpenCode Go" (the
canonical one with all 14 catalog models) and "Opencode_Go" (a phantom
group containing one self-referential entry).
Three structural causes, all in api/config.py:_build_available_models_uncached:
1. **Detection-path id leakage.** The detection block at line ~1980
reads cfg["providers"] keys verbatim. If the user's config has
``providers.opencode_go.api_key`` (underscore variant) AND another
path adds the canonical ``opencode-go`` (e.g. via active_provider),
both end up in detected_providers and the build loop creates two
distinct provider groups with the second labelled via the
``pid.title()`` fallback as ``"Opencode_Go"``.
2. **Injection-block rogue model.** The default-model injection block
at line ~2598 puts ANY ``model.default`` string into the picker as
a fake option. A stray ``model.default: opencode_go`` (provider id
mistakenly used as a model id) surfaces as a phantom model
labelled ``"Opencode GO"``.
3. **Empty-group bleed.** When a non-canonical provider id makes it
into detected_providers but has no entry in _PROVIDER_MODELS, the
build loop creates an optgroup with zero models — pure UI noise.
This PR addresses all three:
- **New `_canonicalise_provider_id()` helper** that folds underscores
to hyphens, lowercases, and applies alias resolution only when the
alias target is itself a canonical id in `_PROVIDER_DISPLAY`. The
last constraint avoids round-tripping ``x-ai`` (canonical) through
the alias table to ``xai`` (which the WebUI doesn't index by).
- **Detection-path canonicalisation.** The cfg["providers"] scan
applies the helper before adding to detected_providers. Same
treatment in the only_show_configured intersection so that mode
doesn't accidentally exclude the canonical id when configured_providers
only contains the underscore-variant key.
- **Post-collection dedup pass** that re-canonicalises every entry in
detected_providers — belt-and-braces against future regressions in
any of the ~25 ``detected_providers.add(...)`` callsites without
auditing each one. Idempotent for already-canonical ids.
- **Provider-id guard on the model.default injection block.** When
the injected value matches a known provider display name or alias
(after underscore/case normalisation), skip the injection and emit
a `logger.warning` instead. Real unknown model ids (newly released
models, custom endpoints) still get injected — only provider-shaped
values are rejected.
- **Empty-group filter at end of build.** Drop optgroups with zero
models. Custom: groups (`provider_id` starts with `custom:`) are
exempt — users may want an empty card visible as a reminder.
Tests
-----
`tests/test_issue1568_duplicate_provider_groups.py` (17 tests):
- TestCanonicaliseProviderId (8): unit tests pinning helper behaviour —
canonical preserved, underscore folded, case folded, aliases
resolved, x-ai not round-tripped, empty input, unknown ids
normalised, idempotence
- TestProviderGroupDedup (4): end-to-end picker behaviour —
underscored providers-key produces ONE group not two (Deor's case),
uppercase providers-key collapsed, aliased keys (z-ai → zai)
collapsed, happy path unchanged
- TestDefaultModelProviderIdGuard (3): provider id as model.default
doesn't inject phantom + WARNING logged; alias as model.default also
caught; legitimate unknown model IDs (forward-compat) still injected
- TestEmptyGroupFilter (2): empty optgroups dropped from picker;
custom: providers exempted from filter
Plus one structural test fix in
`tests/test_issue604_all_providers_model_picker.py:test_cfg_providers_only_adds_known`
— widened the regex window from 500 to 1500 chars so the new
documentation comment block doesn't push `_PROVIDER_MODELS` past the
substring slice. Pre-existing brittle window pattern, not a new issue.
Verification
------------
Live on port 8789 with Deor's exact reproduction config
(`providers.opencode_go.api_key` + `model.provider: opencode-go`):
/api/models groups: 1 (was 2)

Wrap all /api/crons* endpoints in cron_profile_context so the TLS-active
profile's jobs.json is read/written, not the process-default one.
Before: cron.jobs._get_jobs_file() reads HERMES_HOME from os.environ
(process-global) at call time, bypassing WebUI's per-request thread-local
profile. Result: the Scheduled jobs panel always showed the default
profile's jobs regardless of which profile the user selected via cookie,
and CRUD operations silently wrote to the wrong jobs.json.
Fix:
- api/profiles.py: new cron_profile_context (HTTP/TLS) and
cron_profile_context_for_home (worker threads) context managers. Both
hold a module-level lock, swap os.environ['HERMES_HOME'], and re-patch
cron.jobs module-level constants (HERMES_DIR/CRON_DIR/JOBS_FILE/
OUTPUT_DIR are import-time snapshots that don't participate in the
module's lazy __getattr__ path).
- api/routes.py: wrap all 12 cron endpoints (GET + POST). For
/api/crons/run, capture the TLS-active home at dispatch time and
pass it into the background thread so cron output lands in the right
profile directory.
Tests: 3 new regression tests in test_scheduled_jobs_profile_isolation.py
cover TLS-based pinning, explicit-home pinning, and serialization of
concurrent contexts. Full cron + profile test suite (24 tests) passes.

Two related dropdown bugs in one PR — same root shape (model-picker
endpoints disagreeing about which Nous Portal models exist) plus the
preemptive UX guard against the picker becoming unusable on large-tier
Nous accounts.
#1567 — Endpoint disagreement
=============================
Reporter (Deor, Discord, May 03 2026) saw Settings → Providers card
showing "Nous Portal — 396 models · OAuth" while the in-conversation
picker dropdown listed only the four hardcoded curated entries.
Two structural causes:
1. ``api/providers.py:get_providers`` iterates ALL OAuth providers
regardless of authentication state and unconditionally live-fetches
the catalog.
2. ``api/config.py:_build_available_models_uncached`` only iterates
providers in ``detected_providers``, gated on
``hermes_cli.models.list_available_providers().authenticated``.
That flag can disagree with ``get_auth_status(<id>).logged_in`` on
some hermes_cli versions.
When the disagreement happens for Nous, the picker silently falls
through to the curated 4-entry static list while the providers card
keeps showing the live catalog — exactly the asymmetry users report.
Plus: the Nous live-fetch branch in `_build_available_models_uncached`
fell back to the same curated 4-entry list when `provider_model_ids`
returned an empty list (transient failure / OAuth refresh in flight),
which doubles down on the disagreement instead of healing it.
UX cap (the design concern Nathan flagged on triage)
====================================================
Even with the disagreement fixed, dumping a 397-model catalog into a
flat dropdown is unusable. We trim the visible picker to a curated
~15-entry featured set when the catalog exceeds 25 models, and surface
the rest under a new ``extra_models`` field so:
- ``/model`` slash autocomplete (commands.js) covers the full catalog
- ``_dynamicModelLabels`` (ui.js) hydrates from both lists, so a model
selected from outside the featured slice still gets a proper label
- The optgroup label gets ``" (15 of 397)"`` appended so the user
understands the dropdown is intentionally trimmed, not broken
- The providers card surfaces ``models_total`` separately so the
header still reads "397 models · OAuth"
- A small "+N more" disclosure pill appears at the end of the rendered
pill list (only fires for non-OAuth providers — OAuth cards never
render pills) with a tooltip pointing at the slash command
Featured selection rules
------------------------
Deterministic; same algorithm runs in both `/api/models` and
`/api/models/live` so background enrichment doesn't undo the trim:
1. Always include the user's currently-selected model (sticky — no
orphan IDs in the dropdown after a refresh)
2. Always include every entry from the curated static
``_PROVIDER_MODELS["nous"]`` list whose id maps onto a live id
3. Top up to 15 by walking ``_NOUS_VENDOR_PRIORITY`` round-robin
(one model per vendor each pass) so no vendor monopolises the slots
Changes by file
===============
api/config.py
- New `_format_nous_label` neighbour: `_NOUS_FEATURED_THRESHOLD = 25`,
`_NOUS_FEATURED_TARGET = 15`, `_NOUS_VENDOR_PRIORITY` tuple,
`_build_nous_featured_set()` helper (~80 LOC)
- `_build_available_models_uncached` Nous branch:
- Apply featured-set cap with sticky-selection signal
- Return `extra_models` alongside `models` for the catalog tail
- Decorate optgroup label with truncation count
- Drop stale-4 fallback when authenticated but live-fetch empty
(omit the group entirely; truth lives in the providers card and
the next cache rebuild will heal it)
- Keep stale-4 fallback when hermes_cli is unavailable (test envs,
package mismatches) — that's a different failure mode
- Detection symmetry: explicit `get_auth_status("nous").logged_in`
check after the existing `list_available_providers()` loop, so the
picker matches the providers card on hermes_cli versions where the
two signals disagree
api/providers.py:get_providers
- Apply same featured-set cap so card body doesn't render 397 pills
- Add `models_total` field reporting full catalog size (used by
frontend for the "N models · OAuth" header text)
api/routes.py:_handle_live_models
- Apply same featured-set cap for `/api/models/live` so background
enrichment via `_fetchLiveModels()` doesn't undo the dropdown trim
- Use sticky-selection from `cfg["model"]["model"]` matching the main
endpoint's logic
static/ui.js:populateModelDropdown
- Hydrate `_dynamicModelLabels` from `g.extra_models` so a selection
outside the visible dropdown still renders with its proper label
static/commands.js:_loadSlashModelSubArgs
- Iterate `group.extra_models` so `/model` autocomplete covers the
full catalog (not just the trimmed featured slice)
static/panels.js:_buildProviderCard
- Header count uses `p.models_total` (full catalog size) instead of
`p.models.length` (trimmed slice)
- Render trailing "+N more" disclosure pill when `models.length <
models_total` with a tooltip pointing at the slash command
static/style.css
- New `.provider-card-model-tag-more` rule (italic, dashed border,
cursor:help, no select) — visually distinct from real model pills
Tests
=====
`tests/test_issue1567_nous_picker_capacity_and_symmetry.py` (20 tests):
- TestBuildNousFeaturedSet (8): unit tests on the helper —
small-catalog no-op, large-catalog cap to target, disjoint+complete
invariants, priority-vendor round-robin guarantee, sticky selection
with and without `@nous:` prefix, curated-flagship preservation,
empty-catalog handling, determinism
- TestApiModelsLargeCatalog (2): /api/models cap behavior end-to-end
on a synthetic 397-model catalog vs a 20-model catalog
- TestNousDetectionSymmetry (2): picker includes Nous when
`get_auth_status` agrees but `list_available_providers` disagrees;
picker omits Nous when both disagree
- TestNousLiveFetchEmpty (2): authenticated + empty-fetch omits group;
hermes_cli unavailable still falls back to static-4
- TestProvidersCardPickerSymmetry (1): both endpoints agree on
exactly the same featured-set IDs + total catalog count
- TestFrontendExtrasContract (4): static-source assertions pinning
the JS contract for `extra_models`, `models_total`, and the "+N more"
disclosure
Verified live on port 8789 (30-model catalog):
- /api/models Nous group: provider="Nous Portal (15 of 30)", 15 models,
15 extra_models
- /api/models/live?provider=nous: 15 entries (matches main path)
- /api/providers Nous card: models_total=30, models=15
- Browser dropdown after backfill: 15 options, 30 entries in
_dynamicModelLabels
- Sticky selection: Claude Opus 4.7 (the active model) in the featured
slice as expected

Settings password silently no-opped when HERMES_WEBUI_PASSWORD was set:
the env var takes precedence in api.auth.get_password_hash(), but the UI
happily POSTed _set_password and returned a green "Saved" toast while
every subsequent login still required the env-var password. Same for
Disable Auth (_clear_password=true).
Backend (api/routes.py):
- GET /api/settings now exposes password_env_var: bool so the UI knows
the field is shadowed.
- POST /api/settings refuses _set_password and _clear_password with HTTP
409 + a clear message naming HERMES_WEBUI_PASSWORD when the env var is
set. Short-circuits BEFORE save_settings() so settings.json is not
touched.
Frontend (static/index.html, static/panels.js, static/i18n.js):
- Added settingsPasswordEnvLock banner div in the System pane.
- panels.js reads settings.password_env_var, disables the password field,
swaps in a localized "locked" placeholder, reveals the banner, and
hides the Disable Auth button (its POST would 409 anyway).
- New i18n keys password_env_var_locked and password_env_var_locked_placeholder
added to all 9 locales (en, ja, ru, es, de, zh, zh-Hant, pt, ko).
Tests:
- tests/test_issue1560_password_env_var_lock.py: requirement-pinning
(handler exposes flag, 409 on set/clear, banner div, panels.js wiring,
i18n in all 9 locales, env var name in messages, live HTTP smoke when
env unset).
- tests/test_1560_password_env_var_no_op.py: behavioral via FakeHandler
(real status codes for env-set/unset/blank, settings.json hash unchanged
after 409, panels.js disable+banner+placeholder+disable-auth-hidden).
Both files run clean: 23 passed in 2.04s. test_issue1139_password_remote.py
unaffected (4/4 still pass).
(1) api/session_recovery.py: removed misleading dated-format comment claim.
YYYYMMDD_HHMMSS_*.json files don't start with '_' so the underscore-
skip wouldn't apply to them anyway. Replaced with the truthful general
statement: any future non-session JSON marked with the '_' convention
is skipped automatically.
(2) CHANGELOG.md: fixed self-referential typo. v0.50.284 obviously couldn't
have said 'v0.50.285' inside its release notes — the quoted text was
'after deploying v0.50.284'.
Pure documentation. No behavior change. Tests still pass (8/8 in
tests/test_metadata_save_wipe_1558.py).
v0.50.284 shipped startup self-heal in api/session_recovery.py that
crashed on the very first JSON file it scanned in the production
session directory. Verified live on the prod server immediately after
the v0.50.284 deploy:
[recovery] startup recovery failed: 'list' object has no attribute 'get'
Root cause: the production session dir contains _index.json — a
top-level LIST of session metadata dicts (not a dict). _msg_count()
did data.get('messages') which raises AttributeError on a list.
The broad except Exception in server.py's startup hook swallowed the
error and the recovery silently no-op'd for every user — defeating
the entire purpose of the v0.50.284 release.
Fix is three small defensive changes:
1. _msg_count() — added isinstance(data, dict) guard. Non-dict-shaped
JSON files now return -1 (the harmless 'unknown count' sentinel)
instead of raising AttributeError.
2. recover_all_sessions_on_startup() — skips any file whose name starts
with '_' (the existing project convention for non-session metadata
files like _index.json). These are convention-marked as system
files, not session payloads.
3. recover_all_sessions_on_startup() — wraps recover_session(path) in
try/except Exception so a single malformed file can't break recovery
for the rest. Logs and continues.
2 new regression tests:
- test_recover_all_sessions_on_startup_skips_non_session_index_json
- test_msg_count_returns_neg1_for_non_dict_top_level
4026 → 4028 tests passing (+2).
Net effect: any user wiped between v0.50.279 and v0.50.284 deploys
whose session has a .bak shadow will now get auto-recovered on first
launch of v0.50.285, as v0.50.284's release notes promised.
Closes#1558 (follow-up — the original P0 was closed by v0.50.284 but
the recovery half didn't actually run in production).
Both flagged by pre-release Opus advisor; both clearly defensive and small
enough to absorb in-release per the reviewer-flagged-fix-in-release-not-followup
policy.
SHOULD-FIX #1 (api/routes.py:_clear_stale_stream_state, ~25 LOC):
After the metadata-only reload (#1559 Layer 2), the local 'session'
variable is reassigned to the full-load object but the caller still holds
the original metadata-only stub. /api/session then returns the stale
active_stream_id at routes.py:1791, causing the frontend to attempt one
ghost SSE reconnect before recovering. Fix: capture original_stub at
function entry, then patch its in-memory active_stream_id and pending_*
fields to None after both the early-return (full-load already cleared)
path AND the successful-mutation path. Now the caller's read returns
fresh state, no ghost reconnect.
SHOULD-FIX #2 (api/models.py:Session.save, ~20 LOC):
The .bak write at api/models.py:436 used write_text() which truncates-
then-writes — a crash mid-write or concurrent backup-producing save
could leave a torn .bak. Recovery defends correctly (JSONDecodeError →
returns -1 → 'no_action'), so the failure mode was 'backup lost' not
'spurious restore'. Fix: tmp + os.replace pattern matching the main file
write at line 446-453. Now backup either lands cleanly or doesn't land
at all.
4026/4026 tests pass post-absorb.
The PR title and body correctly say 'Closes #1558' but every code comment,
the test file name, error-message strings, docstrings, and the original
commit body referenced #1557 instead. Independent reviewer flagged this:
> The 17 wrong references won't auto-close issue #1558 from the commit
> message — and the test file name will be misleading for future archeology.
> Worth a one-pass s/#1557/#1558/g (and rename test file →

- api/routes.py (2 refs in _clear_stale_stream_state docstring + log)
- api/session_recovery.py (3 refs)
- server.py (3 refs in startup self-heal block)
Verified: 6/6 tests in tests/test_metadata_save_wipe_1558.py pass
with the renamed file + updated references.
v0.50.279 introduced api.routes._clear_stale_stream_state() (#1525) which
calls session.save() to clear stale active_stream_id/pending_* fields. The
helper is called from /api/session and /api/session/status — both of which
load the session with metadata_only=True. Session.load_metadata_only()
synthesizes a stub with messages=[] (its whole purpose: fast metadata read
without parsing the 400KB+ messages array). Session.save() unconditionally
writes self.messages to disk via os.replace(), so saving a metadata-only
stub atomically overwrites the on-disk JSON with messages=[], wiping the
entire conversation.
Production trigger: every SSE reconnect cycle after a server restart polls
/api/session/status, which fans out to _clear_stale_stream_state, which
saves the metadata-only stub. The user reported losing 1000+ message
conversations and seeing 'Reconnecting…' loops on every prompt — the
reconnect loop kept the cycle running until the conversation was empty.
Fix: three layers, defense in depth.
(1) api/models.py: load_metadata_only() now sets _loaded_metadata_only=True
on the returned stub. Session.save() raises RuntimeError if that flag
is set — a hard guard so any future caller making the same mistake
cannot wipe data, only crash visibly.
(2) api/routes.py: _clear_stale_stream_state() now detects the metadata-only
flag and re-loads the full session with metadata_only=False before
mutating persisted state. The full-load path also runs
_repair_stale_pending() which independently clears the stream flags,
so the explicit clear becomes a no-op in most cases — but messages
stay intact.
(3) api/models.py + api/session_recovery.py: every save() that would
SHRINK the messages array (the precise failure shape of #1557) first
snapshots the previous file to <sid>.json.bak. Server.py runs
recover_all_sessions_on_startup() at boot — any session whose live
JSON has fewer messages than its .bak is restored automatically.
Idempotent on clean state. Backup overhead is zero on the normal
grow-the-conversation path.
Reproducer (master): test_metadata_only_save_does_not_wipe_messages goes
from 1000 messages to 0 in a single save() call. After the fix, 1000
messages survive.
Tests: 6 new regression tests in tests/test_metadata_save_wipe_1557.py
covering all three layers. Full pytest: 4019 → 4025 (+6, all green).
Live verified on port 8789: write 1000-msg session with stale active_stream_id,
hit /api/session/status, /api/session — file ends with 1002 messages
(_repair_stale_pending injects an error-marker pair on full reload, harmless
existing behavior), active_stream_id cleared, pending cleared, no Reconnecting
loop.
Closes#1557.

Augments @bergeouss's PR #1548 v2 with the structural fix the issue
actually requested. The original PR added 5 hardcoded entries to
_FALLBACK_MODELS which would rot fast as OpenRouter's free-tier roster
turns over monthly.
Adds proper live-fetch logic to the OpenRouter group population so the
free-tier list stays fresh without requiring a code release every time
a new free model lands.
api/config.py:2120 — replaces the static _FALLBACK_MODELS slice with:
1. Live curated catalog via hermes_cli.models.fetch_openrouter_models()
— applies the tool-support filter (Kilo-Org/kilocode#9068).
2. Free-tier live fetch — direct call to https://openrouter.ai/api/v1/models,
filtered to free-tier-only (pricing.prompt == 0 AND pricing.completion
== 0, OR :free suffix), bypasses the tool-support filter so newly-added
free variants appear even before OpenRouter annotates them with tools.
Capped at 30 entries to keep the picker usable.
3. Defense-in-depth fallback to _FALLBACK_MODELS (which retains
@bergeouss's hardcoded list for offline / test envs).
4. Deduplication via seen_ids — model in both surfaces appears once.
5 new tests + 1 fixed test in tests/test_minimax_provider.py (scoped the
provider='MiniMax' assertion to direct-MiniMax routes by filtering for
'minimax/' prefix and excluding ':free' since the OpenRouter free-tier
variant minimax/minimax-m2.5:free correctly carries provider='OpenRouter').

Per review observation on PR #1544: the docstring claimed
'Gemini 3.1 Pro Preview' and 'Nemotron 3 Super 120B A12B' but the
helper reuses _format_ollama_label's 3-letter-token rule, which
uppercases 'PRO' (and the existing rule for tokens like 'a12b'
renders 'A12b' not 'A12B'). Update the examples to match actual
behavior — labels are unchanged, only the docstring.
Pure-comment change, no behavioral effect. Test counts unchanged
(4013 passed).

#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.
Test counts:
- Full pytest: 4013 passed, 2 skipped, 3 xpassed, 0 failures
(was 3990 → 4013, +23 from this PR).
- QA harness pytest: 20 passed.
- Browser API sanity: 11/11 passed.
- Agent Browser CDP: 21/23 passed (the 2 SSE liveness failures
reproduce on master and are unrelated to this PR).
Spliced from #1531 by @Asunfly: take Change-1 only (the actual bug fix +
cache signature inclusion) and skip Change-2 (auxiliary title-route
extra_body change) which is a separate scope concern.
## What
Two surgical fixes in api/streaming.py:
1. Line 1820 — `_cfg.cfg.get(...)` → `_cfg.get(...)`. `get_config()` returns
a plain dict (not a wrapper exposing `.cfg`). The buggy line raised
AttributeError that the surrounding try/except swallowed, so
`_reasoning_config` was always None regardless of what `/reasoning
<level>` had been set to. Verified locally — `api/streaming.py:1959`
already correctly used `_cfg.get(...)` in the same function, so the
same `_cfg` was being read two different ways in one file.
2. Line 1888 — added `_reasoning_config or {}` to `_sig_blob`. Without
this, switching effort mid-session would fail to take effect because
the per-session agent cache key would still match the old entry.
Mirrors how `resolved_provider` / `resolved_base_url` already
participate in the signature.
## Why splice instead of merge #1531 directly
@Asunfly force-pushed a Change-2 onto #1531 after the original review
that removes `extra_body={"reasoning": {"enabled": False}}` from
`generate_title_raw_via_aux` (the auxiliary title-generation route).
That intent is reasonable (let operator-configured `extra_body.reasoning`
flow through to the title route) but it touches a different surface and
deserves its own PR.
The narrow concern is operators who selected a reasoning-capable
auxiliary title model without explicitly setting
`reasoning.enabled=False` in the task config — pre-Change-2 the WebUI
defended against accidental reasoning on the title hot path; post-Change-2
those configs would reason on every new conversation`s title, with cost
and latency implications.
## What is NOT in this PR
- The `generate_title_raw_via_aux` extra_body refactor (Change-2 from #1531).
- The `test_does_not_override_configured_reasoning_extra_body` test (guards
Change-2). Asunfly can re-open that as its own focused PR.
## Tests
Two new R17b/R17c regression assertions in tests/test_regressions.py:
- `test_streaming_reads_reasoning_effort_from_config_dict` — static-source
guard: `_cfg.cfg` must not return to streaming.py
- `test_streaming_agent_cache_signature_includes_reasoning_config` —
catches removal of `_reasoning_config` from `_sig_blob`
## Closes
- Closes#1531 (the Change-1 portion ships here; Asunfly can re-open
Change-2 as a separate PR if desired)

Merge conflict resolution: kept HEAD's `CACHE_NAME = 'hermes-shell-__WEBUI_VERSION__'` (post-#1517 rename) over PR #1525's `'hermes-shell-__CACHE_VERSION__-stale-stream-cleanup1'` manual suffix. The renamed placeholder still auto-bumps with each release through the `quote(WEBUI_VERSION, safe="")` substitution, so the manual `-stale-stream-cleanup1` suffix is no longer needed to force-update existing service workers — the natural version bump (v0.50.278 → v0.50.279) already invalidates the old cache via `caches.delete(k)` for `k !== CACHE_NAME` in the SW activate handler. No behavioral regression: the SW cache still bumps on this release, just via the canonical version-token path.
