Codex 5th CORE: the ownership set only covered static _PROVIDER_MODELS, not the
active provider's own config.yaml providers.<active>.models allowlist. So an
active provider defined purely via providers: (no static catalog) could be
hijacked by another slug's overlapping entry earlier in config order. Fix folds
the active provider's own providers: allowlist (list + dict shapes, copilot
excluded) into _provider_models_set — completing the ownership model so the
active provider owns its declared models from EITHER the static catalog OR its
own providers: entry. Regression test (fail-without-fix verified). 40 model_resolver
tests green.

Codex 4th CORE (root latent bug in the shared canonicalizer): _canonicalise_provider_id
only accepted an alias resolution if the target was in _PROVIDER_DISPLAY. But some
canonical targets (e.g. 'gemini') are indexed in _PROVIDER_MODELS and NOT
_PROVIDER_DISPLAY, so 'google-gemini'->'gemini' was rejected and returned raw
'google-gemini' — leaving the ownership guard empty and letting providers.openai.models
hijack an active Gemini-owned model. Fix mirrors the direct-hit check (line 1445):
accept alias targets in EITHER _PROVIDER_DISPLAY OR _PROVIDER_MODELS. This is the
root fix for the whole alias-canonicalization class (gemini/google-gemini/
google-ai-studio etc.), not just the reported site. Blast-radius verified: 81
canonicalise/provider-alias tests across 5 files still green; x-ai still stays x-ai,
opencode_go still folds. Gemini regression test added (fail-without-fix verified).

Codex 3rd CORE (pre-existing latent bug the providers: scan exposes): the
_provider_models_set ownership lookup used the RAW config_provider (e.g. 'z-ai')
but _PROVIDER_MODELS is keyed by canonical slug ('zai'), so an aliased active
provider got an empty ownership set -> _skip_custom_providers guard-2 silently
failed -> another providers.<slug>.models entry could hijack an active-owned
model (verified: active z-ai + glm-5 + providers.openai.models.glm-5 -> openai).
Fix: canonicalise config_provider before the _PROVIDER_MODELS lookup (and reuse
the canonical slug for the scan's ownership guard). Regression test with an
aliased active provider (verified fail-without-fix).
This is the root-cause fix for the alias class — the ownership guard now holds
for every aliased provider (zai/kilo/etc.), not just the reported site.

Codex 2nd CORE: the new providers: scan didn't honor the _skip_custom_providers
active/default ownership guard (config.py:2535) that the custom_providers scan
uses. So with an active provider (e.g. ai-gateway) + model.default=gpt-5 AND a
providers.openai.models.gpt-5 entry, the scan hijacked gpt-5 to openai instead of
the active ai-gateway path. Fix: when _skip_custom_providers is true, the
providers: scan only considers the active provider's own canonical slug (skip all
other slugs). Regression tests: active-provider-owns-default not hijacked (fails
without fix); active provider's OWN providers: entry still matches.

Gate-cert (nesquena-hermes) + Codex found 1 CORE: akay64's new providers: scan in
resolve_model_provider() iterated ALL providers.<slug>.models INCLUDING
providers.copilot.models — but that key is a documented per-model SETTINGS map
(reasoning_effort/limits), NOT a routing allowlist (config.py exception). So a
Copilot per-model settings entry hijacked that model's routing to Copilot
(Codex reproduced gpt-5 -> copilot). Fix (Codex-exact): skip copilot in the scan.
Added the regression tests the PR shipped 0 of: user-defined allowlist routes;
active-openai + providers.copilot.models (dict + list shapes) stays openai
(both verified to fail without the exclusion).

* fix: keep custom provider when model id has known-provider prefix (#4210)
Siblings of #3872 (v0.51.349, custom provider with a configured base_url
preserves intrinsic routing prefixes). The base_url unset variant of
the same bug was missed: with provider=custom or custom:<slug> and no
base_url set, a model id like 'x-ai/grok-2' or 'google/gemma-2' was
hijacked to provider='openrouter', base_url=None. The backend then
failed to initialize with 'RuntimeError: No LLM provider configured'
because the user had no OpenRouter credentials configured.
resolve_model_provider() now applies the same _is_custom exemption the
config_base_url branch already carries to the cross-provider redirect
at the end of the slash branch. The custom provider keeps the request
and the full model id; real first-party providers pointed at an
OpenAI-compatible proxy (e.g. provider=openai + base_url=litellm) are
unaffected because their strip path is in the base_url branch and the
'prefix == config_provider' branch above the change.
Verified:
- test_model_resolver.py 32 passed (30 existing + 2 new RED tests)
- test_custom_provider_bare_model_reasoning.py 34 passed
- Pre-existing F401 (api/config.py:23,24,28) are not introduced by
this change; same 3 errors exist on upstream/master.

A bare 'custom' provider with a remote base_url is a vendor-routing proxy
(LiteLLM, Bedrock gateway, etc.). A slashed model id like bedrock/opus-4-6 is
intrinsic — the proxy routes on the full string. The prior heuristic stripped
ANY known-provider prefix (bedrock is also a provider name), truncating it to
opus-4-6 and causing 403 'model not allowed'.
Fix: in the custom-base_url branch, strip the prefix only when (a) the configured
provider is a real first-party provider pointed at an OpenAI-compatible proxy
(provider=openai + proxy base_url — the #433 path), OR (b) for a bare 'custom'
provider, the bare id is genuinely a first-party model of that prefix's catalog
(openai/gpt-5.4 -> gpt-5.4, since gpt-5.4 IS an OpenAI model). An intrinsic
routing prefix whose bare id is NOT first-party of that namespace is preserved
(bedrock/opus-4-6 stays whole). Unknown prefixes (zai-org/...) preserved as before.
Both prior behaviors work in tandem with the fix:
- #433 sprint40: bare custom + openai/gpt-5.4 -> gpt-5.4 (redundant, strip)
- #433 model_resolver: provider=openai + google/gemma -> gemma (proxy strip)
- #548: custom + zai-org/GLM-5.1 -> preserved (unknown prefix)
- #1625: custom + loopback base_url -> preserved (local server)
- #3872: custom + bedrock/opus-4-6 -> preserved (intrinsic vendor prefix)
Adds regression tests covering all of the above.

Closes#1623 — Lower SSE app heartbeat from 30s to 5s at every long-lived
handler (main agent, terminal, gateway-watcher, approval-poller, clarify-poller).
Kernel TCP keepalive declares peer dead at 25s worst-case (10s KEEPIDLE +
5s KEEPINTVL * 3 KEEPCNT, added v0.50.289 #1581). 30s app heartbeat let the
kernel tear sockets down on flaky networks before the app sent its first
keepalive byte — drops at ~10s during long thinking phases. New named
constant _SSE_HEARTBEAT_INTERVAL_SECONDS=5; regression test pins the
inequality (app_heartbeat * 2 <= kernel_window) so future tuning can't
re-introduce the misalignment.
Closes#1624 — Add 30s grace period to _repair_stale_pending() trigger.
Without it, any narrow race between the streaming thread clearing
pending_user_message and STREAMS.pop(stream_id) produces a false-positive
'Previous turn did not complete.' marker on a turn that finished correctly
(reproducible after every command-approval turn). Defense-in-depth, not
the root-cause fix — the actual streaming-thread leak path is tracked
separately. Falsy pending_started_at (legacy sidecars) treated as
'old enough' so legitimate legacy-data recovery still works. Plus
logger.warning telemetry on every legitimate repair so the next batch of
user reports tells us whether the underlying race still fires.
Closes#1625 — Local model servers (LM Studio, Ollama, llama.cpp, vLLM,
TabbyAPI, koboldcpp, textgen-webui) now keep the full HuggingFace-style
model id (e.g. 'qwen/qwen3.6-27b' instead of stripped 'qwen3.6-27b'). New
_LOCAL_SERVER_PROVIDERS set + _base_url_points_at_local_server() loopback/
RFC1918 heuristic — either signal triggers no-strip. Backward compat
preserved for OpenAI-compatible proxies on public hosts (LiteLLM at
litellm.example.com still strips openai/gpt-5.4 -> gpt-5.4). Updated the
existing #230/#433 test to reflect that #1625 supersedes the strip-on-custom
rule for loopback hosts (see api/config.py and test_model_resolver.py
docstring update). Reported by @akarichan8231 in Discord on 2026-05-04.
42 regression tests across:
tests/test_issue1623_sse_heartbeat_alignment.py (3)
tests/test_issue1624_repair_stale_pending_grace.py (9)
tests/test_issue1625_local_server_model_id_preservation.py (30)
4142 -> 4184 passing. 0 regressions.
When multiple providers expose the same bare model ID (e.g. two custom
providers both listing gpt-5.4), the model picker cannot distinguish
them — both rows appear active and clicking the other provider's copy
is a no-op.
Fix:
- Add _deduplicate_model_ids() post-process in api/config.py that
detects duplicate bare model IDs across groups and prefixes
collisions with @provider_id: so each entry is globally unique
- Update norm() regex in static/ui.js to strip @provider: prefixes
for fuzzy matching, so existing sessions with bare model IDs still
restore correctly
- First occurrence stays bare for backward compatibility with sessions
that already store the bare model name
- Update test_model_resolver to be dedup-aware
Closes#1228
Root cause of persistent CI failure on `test_custom_endpoint_uses_model_config_api_key_for_model_discovery`:
The helper `_available_models_with_full_cfg` and the failing test itself both do:
```python
try:
_cfg._cfg_mtime = stat().st_mtime
except Exception:
pass # ← leaves _cfg_mtime at stale value from a prior test
```
On CI (no `~/.hermes/config.yaml`), `stat()` raises `OSError`. `get_available_models()` then sees `_current_mtime=0.0 != _cfg_mtime=<stale from prior test>`, calls `reload_config()`, overwrites the test's in-memory `cfg`, `api_key` disappears, `urlopen` is never called, `captured['auth']` raises `KeyError`.
**Fix:** The `except` clause now sets `_cfg._cfg_mtime = 0.0` (matching what `get_available_models()` will see when `stat()` also fails), so the reload guard becomes a no-op and the test's `cfg` mutation survives. Same pattern already used correctly in `test_custom_provider_display_name.py` and `test_ttl_cache.py`.
Verified with `HERMES_CONFIG_PATH=/tmp/nonexistent` to reproduce the CI no-config condition locally. 1747/1747 full suite.
Fixes the CI failure introduced by #817: test_model_resolver::test_custom_endpoint_uses_model_config_api_key_for_model_discovery was failing with KeyError: 'auth' due to the 60s TTL cache in get_available_models() being populated by test_byok_model_dropdown.py tests that ran earlier. Added autouse _isolate_models_cache fixture to 5 test files. Full suite 1747/1747, QA harness green.
* fix: custom provider with slash model name no longer rerouted to OpenRouter (#255)
When base_url is configured in config.yaml, resolve_model_provider() now
trusts the configured provider/base_url entirely and skips the slash-based
OpenRouter heuristic. Fixes google/gemma-4-26b-a4b with provider:custom
being silently routed to OpenRouter, resulting in 401 errors.
Fixes#230
* test: mobile layout regression suite — 14 tests for every QA run (#254)
Adds tests/test_mobile_layout.py with 14 static regression tests that run
on every QA pass to catch mobile layout breakage before it reaches prod.
Covers: breakpoints at 900px/640px, right panel slide-over CSS, mobile
overlay, bottom nav, files button, profile dropdown z-index, chip overflow,
workspace close, 100dvh, 44px touch targets, 16px font-size on textarea.
* feat: /skills slash command lists and filters available Hermes skills (#257)
Adds /skills [query] command to commands.js. Fetches from /api/skills,
groups by category (alphabetically sorted), displays as a formatted
assistant message. Optional query filters by name, description, or category.
i18n keys added for en, de, zh, zh-Hant. 1 regression test added.
Fixes#248
* feat: shared app dialogs replace native confirm()/prompt() calls (#251)
Adds showConfirmDialog() and showPromptDialog() helpers to ui.js, backed
by a themed #appDialogOverlay. Replaces all 11 native browser confirm/prompt
call sites across panels.js, sessions.js, ui.js, workspace.js.
Supports: danger mode, keyboard focus trap (Tab/Escape/Enter), focus restore,
ARIA roles, mobile-responsive stacked buttons at 640px. i18n for en/de/zh/zh-Hant.
5 new tests in test_sprint33.py verify markup, CSS, helpers, and absence of
native dialog calls.
Extracted from PR #242.
* fix: Android Chrome mobile — workspace panel close + profile dropdown (#256)
Fix#247: toggleMobileFiles() now shows/hides the mobile overlay when
toggling the right workspace panel. New closeMobileFiles() helper closes
the panel with correct overlay state tracking. Overlay onclick calls both
closeMobileSidebar() and closeMobileFiles(). Mobile-only close button (x)
added to workspace panel header.
Fix#246: profile dropdown uses position:fixed;top:56px;right:8px at
max-width:900px, escaping the overflow-x:auto stacking context that was
clipping it on Android Chrome.
Fix applied during review: closeMobileSidebar() now checks if the right
panel is still open before hiding the overlay, preventing the overlay from
disappearing when only the sidebar is closed.
Fixes#247Fixes#246
* feat: session ⋯ action dropdown replaces per-row buttons (#252)
Replaces the 5 per-row hover action buttons (pin/move/archive/duplicate/trash)
with a single ⋯ trigger that opens a positioned dropdown menu. Menu has full
keyboard (Escape), click-outside, scroll, and resize-reposition handling.
Position:fixed prevents sidebar clipping.
5 actions: Pin/Unpin, Move to project, Archive/Unarchive, Duplicate, Delete
(danger style). Each with icon and descriptive subtitle.
Updated test_sprint16.py: test_sessions_js_uses_action_menu_not_per_row_buttons
asserts the new trigger and menu functions exist, old per-row classes are gone.

* fix: decode HTML entities before markdown processing + zh/zh-Hant translations (#239)
Adds decode() helper in renderMd() to fix double-escaping of HTML entities
from LLM output (e.g. <code> becoming &lt;code&gt; instead
of rendering). XSS-safe: decode runs before esc(), only 5 entity patterns.
Also adds 40+ missing zh (Simplified Chinese) translation keys and a new
zh-Hant (Traditional Chinese) locale with 163 keys.
Fix applied: removed duplicate settings_label_notifications key in both
zh and zh-Hant locales.
Fixes#240
* fix: restore custom model list discovery with config api key (#238)
get_available_models() now reads api_key from config.yaml before env vars:
1. model.api_key
2. providers.<active>.api_key / providers.custom.api_key
3. env var fallbacks (HERMES_API_KEY, OPENAI_API_KEY, etc.)
Also adds OpenAI/Python User-Agent header and a regression test covering
authenticated /v1/models discovery.
Fixes users with LM Studio / Ollama custom endpoints configured in
config.yaml whose model picker silently collapsed to the default model.
* feat: Docker UID/GID matching to avoid root-owned .hermes files (#237)
Adds docker_init.bash with hermeswebuitoo/hermeswebui user pattern so
container files match the host user UID/GID. Prevents .hermes volume
mounts from being owned by root when using a non-root host user.
Configure via WANTED_UID and WANTED_GID env vars (default 1000/1000).
Readme updated with setup instructions.
Fix applied: removed duplicate WANTED_GID=1000 line in docker-compose.yml
that was overriding the ${GID:-1000} variable expansion.
* security: redact credentials from API responses and fix credential file permissions (#243)
Adds response-layer credential redaction to three endpoints:
- GET /api/session — messages[], tool_calls[], and title
- GET /api/session/export — download also redacted
- SSE done event — session payload in stream
- GET /api/memory — MEMORY.md and USER.md content
Adds api/startup.py with fix_credential_permissions() at server startup.
Adds 13 tests in tests/test_security_redaction.py.
Merged with #237 container detection changes in server.py.
* fix: cancel button now interrupts agent and cleans up UI state (#244)
Wires agent.interrupt() into cancel_stream() so the backend actually
stops tool execution when the user clicks Cancel, rather than only
stopping the SSE stream while the agent keeps running.
Changes:
- api/config.py: adds AGENT_INSTANCES dict (stream_id -> AIAgent)
- api/streaming.py: stores agent in AGENT_INSTANCES after creation,
checks CANCEL_FLAGS immediately after store (race condition fix),
calls agent.interrupt() in cancel_stream(), cleans up in finally block
- static/boot.js: removes stale setStatus(cancelling) call
- static/messages.js: setBusy(false)/setStatus('') unconditionally on cancel
Race condition fix: after storing agent in AGENT_INSTANCES, immediately
checks if CANCEL_FLAGS[stream_id] is already set (cancel arrived during
agent init) and interrupts before starting. Check is inside the same
STREAMS_LOCK acquisition, making it atomic.
New test file: tests/test_cancel_interrupt.py with 6 unit tests.

* fix: do not build phantom "Custom" group when active provider is set
When model.provider is a real provider (e.g. openai-codex) and model.base_url
is configured, hermes_cli reports 'custom' as an authenticated provider. The
WebUI model picker was building a separate "Custom" group for it and parking
the configured default_model there instead of under the active provider's
group — diverging from the TUI which correctly shows the model under its
configured provider.
Two fixes in api/config.py get_available_models():
1. Discard 'custom' from detected_providers when active_provider is set and
isn't 'custom' itself. The base_url belongs to the active provider.
2. Replace the substring-based default-model injection check with an exact
match against _PROVIDER_DISPLAY. The old check `active_provider.lower() in
g.get('provider', '').lower()` silently failed for hyphenated IDs like
'openai-codex' vs display name 'OpenAI Codex' (hyphen vs. space),
falling through to groups[0] and landing the model in the alphabetical
first group instead.
Adds two regression tests in tests/test_model_resolver.py covering both
conditions.
* fix: do not build phantom Custom group when active provider is set
Two bugs in get_available_models():
1. Phantom Custom group: hermes_cli reports 'custom' as authenticated
whenever model.base_url is set. With provider=openai-codex + base_url,
detected_providers contained both 'openai-codex' and 'custom', producing
a duplicate group. Fixed by discarding 'custom' from detected_providers
when the active provider is any real named provider.
2. Hyphen/space mismatch in default_model injection: the substring check
'openai-codex' in 'openai codex' is False (hyphen vs space), causing the
default model to fall through to groups[0] (alphabetically first provider)
instead of the active provider group. Fixed by using _PROVIDER_DISPLAY
for exact display-name comparison.
Also fixes test helper _available_models_with_full_cfg to clear model env
vars during the call, preventing real hermes profile env from leaking into
the test assertions.

The previous fix (#142) prefixed non-default provider models with
'provider/model' which then hit the cross-provider guard and routed
to OpenRouter — worse than before for users without an OpenRouter key.
New approach: non-default provider models use '@provider:model' format
(e.g. @minimax:MiniMax-M2.7). resolve_model_provider() parses this
hint and returns (bare_model, provider, None). streaming.py and
routes.py then pass the resolved provider to
resolve_runtime_provider(requested=provider) which gets the correct
per-provider API key and base_url from hermes-agent.
This uses the agent's own credential resolution instead of reinventing
routing logic in the webui.
Fixes#138

* fix: prefix non-default provider model IDs for correct routing
When multiple providers are configured, models from non-default providers
(e.g. MiniMax when Anthropic is default) were sent as bare names without
provider context. resolve_model_provider() couldn't determine the target
provider and routed them to the default provider's API, which failed.
Fix: get_available_models() now prefixes model IDs with the provider name
(e.g. minimax/MiniMax-M2.7) for providers that are NOT the active config
provider. The default provider's models keep bare names for direct API
routing. This matches the existing pattern for OpenRouter models.
Added 2 tests to test_model_resolver.py for cross-provider routing.
Closes#138

* fix: model prefix — null-guard, case normalization, mutation safety, tests
Four fixes on top of original PR:
- active_provider=None guard: without a confirmed provider all models were
being prefixed. Only prefix when active_provider is set.
- Case normalisation: compare pid against active_provider.lower() so
config.yaml entries like 'Anthropic' match pid 'anthropic'.
- Mutation safety: default branch used raw reference to _PROVIDER_MODELS[pid];
the default_model injector later calls list.insert() on that reference,
permanently mutating the shared constant. Both branches now use a copy.
- Already-prefixed model IDs pass through as-is (no double-prefix).
Added 3 tests for get_available_models() prefix behaviour:
- Non-default provider models are prefixed
- Active provider's own entries remain bare
- No double-prefix when active_provider is absent

When config has provider=openrouter and model=openrouter/free,
resolve_model_provider() stripped the 'openrouter/' prefix because
prefix == config_provider. This sent 'free' to OpenRouter's API,
which returned 404 (model not found).
OpenRouter always needs the full provider/model path (e.g.
openrouter/free, anthropic/claude-sonnet-4.6). The prefix-stripping
logic is only correct for direct-API providers.
Fix: skip prefix stripping entirely when config_provider is 'openrouter'.
Return the full model_id with provider='openrouter'.
Added 7 unit tests for resolve_model_provider() covering:
- openrouter/free keeps full path (the bug)
- openrouter cross-provider models keep full path
- direct API providers still strip prefix correctly
- cross-provider routing to openrouter
- bare model names use config provider
- empty model returns defaults
