Reshapes the Settings/Models frontend to match the channel-module split
convention (commit 22894ac4 'perf(channels): split Channels.vue...'),
zero behavior change. Paves the way for a follow-up that adds an enabled
column + AddProviderDrawer without bloating useProviders back to monolith.
Frontend split
- useProviders.ts goes from 615-line monolith to a 48-line facade that
composes five single-responsibility slices:
* useProviderList — providers / activeModels / currentProvider,
loaders, status pill, icons
* useProviderForm — create/edit modal + form, save/delete
* useProviderDiscovery — manage-models modal, discovery, connection
and per-model tests
* useProviderOAuth — openai-chatgpt + claude-code OAuth flows
* useProviderPool — manual reprobe (most pool surface inlined to
ProviderInfo.liveness in the prior liveness change)
Cross-composable refs flow via dep-injection arguments — no module-
level state, no circular deps. Each composable stays independently
testable.
- Pure helpers extracted to src/utils:
* safeJson.ts — strict JSON-object parser
* modelProtocol.ts — protocol <-> ChatModel class translation
- Modals (ProviderConfigModal, ManageModelsModal) loaded via
defineAsyncComponent so the route's first paint doesn't drag along
~30KB of form/auth UI.
- el-skeleton placeholder during the initial Promise.all so the page
paints something instead of blank-then-pop.
Layout regression fix
- MainLayout's <keep-alive> slot used :key='workspaceRouteKey' (a
workspace-scoped string), shared between two <component v-if> blocks.
Adding a second keepAlive route would have caused two components to
mount side by side, because Vue saw identical keys and patched in
place across the v-if boundary. Switched the key to
${workspaceRouteKey}:${route.path} so different routes get distinct
vnode identities while workspace switching still busts the cache.
Discovered while implementing the split — the multi-line HTML
comment also had to live OUTSIDE <keep-alive>, since KeepAlive
treats comments as children and rejects 'more than one'.
Embedding section title fix (drive-by)
- EmbeddingModelsSection.vue's scoped style didn't redeclare
.group-title's flex layout, so the icon stacked above the title
text instead of sitting inline. Added the missing flex rules
locally — now matches the local-models / cloud-models group headers.
Verification
- vue-tsc 0 errors.
- Browser end-to-end: 27 cards render correctly, modals open via lazy
load, /channels <-> /settings/models switch four times in a row with
exactly one page title visible at each step (no stacking).
Phase 1 of the model-module refactor: combine pool / cooldown / probe-
completion signals into a single Liveness state surfaced through the
provider DTO, so the dropdown stops listing providers that are provably
unreachable. Zero schema change; one PR backend + frontend.
Backend
- Liveness enum with five mutually-exclusive states: LIVE, COOLDOWN,
REMOVED, UNPROBED, UNCONFIGURED. Computed in ModelProviderService
from AvailableProviderPool / ProviderHealthTracker / ProviderInitProbe
snapshots batched once per listProviders() call.
- ProviderInitProbe.hasBeenProbed exposes a monotonic Set so the UI
can distinguish 'still booting' from 'probed and removed' — without
it the startup window flashes false REMOVED states.
- ProviderInfoDTO gains liveness + unavailableReason +
cooldownRemainingMs + lastProbedAtMs. The legacy 'available' boolean
stays but is now derived from liveness == LIVE so the chat fallback
walker and the dropdown agree about what's usable.
- ProviderInitProbe injected into ModelProviderService via
ObjectProvider to break the startup cycle (probe already depends on
the service).
Frontend
- ProviderInfo type extended with liveness + the three detail fields.
- ModelSelector filters UNCONFIGURED + REMOVED out of the dropdown,
shows COOLDOWN / UNPROBED with a status dot and dimmed rows that the
user can still click to override.
- ProviderCard renders a five-state badge driven by liveness instead
of the old configured + pool-entry combo. Reprobe button now keys
off liveness in {REMOVED, COOLDOWN}.
- useProviders drops loadProviderPool / providerPool — pool data ships
inline on each ProviderInfo, saves a round trip per page load and
keeps a single source of truth.
- i18n: 8 new keys across zh-CN and en-US for liveness labels and the
cooldown countdown tooltips.
Bonus fix (discovered during verification): AgentGraphBuilder.buildOpenAiApi
hard-required a usable API key on every OpenAI-compat provider, ignoring
the per-provider requireApiKey flag. That bug stranded keyless local
runtimes (LM Studio / MLX / llama.cpp) the moment a user actually
launched them; Ollama only worked by accident because its seed row
carries a placeholder string in api_key. keyRequired now honors
requireApiKey, and Spring AI's NoopApiKey is used when no key is needed
so the Authorization header is omitted entirely.
Test
- ModelProviderServiceLivenessTest covers all five Liveness states +
the probe-bean-absent fallback branch.
- vip.mate.llm.** suite (118 tests) green; vue-tsc clean.
- End-to-end browser sanity: 27 raw providers reduce to 6 LIVE groups
in the chat dropdown; LM Studio / MLX / llama.cpp render REMOVED red
badges with reprobe buttons; cloud providers without keys show
UNCONFIGURED.
