Adds explicit user-intent gating to the provider catalog. Fresh installs
get an empty dropdown by default — built-in cloud + local providers
(OpenAI, Anthropic, Ollama, LM Studio, MLX, llama.cpp, etc.) live in a
new 'Add Provider' drawer until the user opts them in. Existing installs
upgrade conservatively: V55 promotes any provider with evidence of use
(real api_key, OAuth token, recent chat usage, or current default model).
Backend
- V55 migration (H2 + MySQL): adds enabled BOOLEAN DEFAULT FALSE on
mate_model_provider, plus 4 promote-to-true UPDATE rules. Also
CREATE INDEX idx_message_runtime_provider_time so the 30-day usage
lookup doesn't full-scan mate_message on heavy users.
- ModelProviderEntity, ProviderInfoDTO: enabled field.
- ModelProviderService:
* listProviders() now filters WHERE enabled = TRUE — chat path,
ModelSelector, Settings/Models main grid see only opted-in rows.
* listCatalog() new — full catalog (enabled + disabled) for the drawer.
* setEnabled(id, enabled) flips the flag, publishes
ModelConfigChangedEvent (re-probe via the existing listener), and
on disable auto-promotes a replacement default model when the
disabled provider owned the current default. Returns EnableResult
so the frontend can fire a toast.
* createCustomProvider sets enabled=true (user just made the row).
- ProviderInitProbe.listConfiguredProviders also filters enabled=true —
no point probing rows the user can't see.
- ModelConfigController: GET /catalog, POST /{id}/enable, POST /{id}/disable.
- Plugin-registered ChatModels are unaffected — they live in
pluginChatModels (in-memory map), don't go through DB listProviders,
so the enabled filter doesn't strand them.
Frontend
- New types: ProviderInfo.enabled, EnableResult.
- New API: catalog / enableProvider / disableProvider.
- New composable useProviderEnablement: catalog ref, drawerOpen,
togglingId, loadCatalog, openDrawer / closeDrawer, enableProvider,
disableProvider (fires defaultSwitchedToast on auto-switch).
- AddProviderDrawer.vue: lazy-loaded, reuses DoctorDrawer's Teleport +
overlay + slide-in panel pattern. Two groups (cloud / local),
unenabled rows surface to the top of each group, enabled rows show
an 'Enabled' badge instead of a button. Mobile: full-screen sheet
that slides up from below.
- ProviderCard: new 'Disable' button with soft-danger styling on
enabled providers — soft-hide that keeps the config; user can
re-enable from the drawer.
- Settings/Models index.vue:
* Two top CTAs: 'Enable Provider' (drawer) and 'Custom' (existing
custom-create modal) — distinct workflows, both surfaced.
* Empty state with prominent 'Enable Provider' CTA when zero
enabled providers — paired with onMounted auto-open of the
drawer (sessionStorage guard so closing it doesn't bring it
back on the next route visit in the same session).
* Deep-link: ?addProvider=1 query forces the drawer open and
strips itself after, so a back/forward doesn't re-fire the open.
- ModelSelector: when groups.length === 0 and not searching, show
'No providers configured -> Configure' CTA linking to
/settings/models?addProvider=1 — the natural flow when a fresh
user opens chat before configuring anything.
- i18n: 13 new keys per locale (zh-CN + en-US) plus common.close.
Migration safety
- Conservative default policy: only rows with concrete evidence of
use are auto-enabled; everything else stays hidden. Upgrade users
may notice unused built-ins disappearing from their dropdown —
that's the intended cleanup.
- mate_message index added so the 30-day usage rule doesn't full-scan
on large installations; FlywayRepairConfig handles redeploy idempotency.
Tests
- ModelProviderServiceEnableTest covers all 7 enable/disable branches:
flag flip + event publish, no-op on already-{enabled,disabled},
default-switch when disabled provider owned current default,
no-switch when default belongs elsewhere, no-replacement returns
unchanged, getDefaultModel exception path, candidates with no
models are skipped.
- ProviderInitProbeTest: helper provider() now sets enabled=true so
the new probe filter doesn't strand existing fixtures.
- vip.mate.llm.** suite: 125 tests green. vue-tsc 0 errors. Browser
page renders with both new buttons + drawer.
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.
UI — Failover priority editor
- ProviderConfigRequest + ProviderInfoDTO carry fallbackPriority
- ModelProviderService.updateProviderConfig persists it (null = unchanged);
toProviderInfo exposes the current value to the UI (defaults to 0)
- ProviderConfigModal advanced panel exposes a number input with hint
- ProviderCard shows a "Fallback #N" badge for chain members so the
priority order is visible at a glance without opening the modal
- 5 new i18n keys (zh + en) — verified to resolve at runtime via i18n.global.t
Backend — Per-provider health tracker
- ProviderHealthTracker: ConcurrentHashMap-backed counters; N consecutive
failures (default 3) push the provider into a cooldown window (default
5 min) during which the chain walker skips it. Success resets both
counter and cooldown atomically. Lazy expiry on lookup so dead entries
do not accumulate.
- ProviderHealthProperties exposed under mateclaw.llm.failover.health.*
with sane production defaults
- New FallbackEntry record (providerId + ChatModel) replaces raw
List<ChatModel> in the chain so the walker can correlate cooldown
state to entries; AgentGraphBuilder.buildFallbackChain returns the
new type
- NodeStreamingChatHelper takes the tracker through a new 4-arg
constructor and consults it before each fallback call; records
success/failure on each chain attempt. Legacy 2/3-arg constructors
preserved as @Deprecated wrappers (synthetic providerId means no
health tracking on the legacy path — that path is opt-out anyway)
Tests
- ProviderHealthTrackerTest (9 tests): below/at threshold, success
reset, cooldown expiry (via reflection on the min-clamp setter),
disabled-tracker no-op, null-providerId safety, per-provider
isolation, snapshot output
- NodeStreamingChatHelperFallbackChainTest updated to FallbackEntry
field type — verifies providerId + ChatModel survive the chain
- 168 tests pass (was 159 + 9 new)
Verification
- mvn test green; vue-tsc clean; live UI confirms i18n resolution
