    • fix(web): switch the pricing card grid to three columns at xl · bee45b58
      The model card grid and its loading skeleton only reached three columns at
      2xl, leaving a two-column layout on common desktop widths. Use the xl
      breakpoint for both and lock it with a test.

    • refactor(task): remove the custom-plugin layer switch · 210734bb
      TaskPluginOverrideEnabled had no UI since the master switch landed, yet
      when left off it marked every third-party plugin "disabled; platform
      unavailable" regardless of its own toggle. Drop the option, env var,
      registry flag, and the dead branch in ListTaskPlugins; the master switch
      and per-plugin toggles are the only two levels now.

    • fix(plugins): make sunoapi alias-safe and lock alias echo across built-ins · 92bc7ff7
      Decode on ctx.upstreamModel || ctx.model and echo ctx.model; fix the
      lyrics/music render branch that read a nonexistent ctx.requestBody.model;
      stop sending empty Accept/Content-Type. Bump sunoapi to 1.0.2. Add an
      alias-echo table test covering every built-in.

    • fix(plugin): suppress factory layer when disabling an overridden task plugin · 6298b0f3
      Disabling a task plugin that has both a factory built-in and an override
      row only flipped the override flag, so the built-in kept routing the same
      models and same-name uploads (e.g. minimax-h3 vs MiniMax-H3) still hit a
      routing conflict. Now the key also enters the disabled-factory set and the
      list reports "disabled" instead of "disabled_fallback" when nothing serves.

    • fix(perf): return hourly success-rate series for model health bar · 5c7cca01
      The perf summary API only returned the last three non-empty buckets as
      bare success rates, so the 24-slot status strip on model cards never lit
      more than three bars and could not show hours without traffic.
      
      Replace recent_success_rates with recent_success_series: one timestamped
      point per hour that had requests, aligned to hour start regardless of
      the configured bucket size. The badge now anchors its 24 slots to the
      client's current hour and places each point by timestamp, leaving hours
      without data gray.

    • fix(web): keep drawer popups interactive and shim storage in tests · 387a4091
      - Portal Combobox and Select popups into the vaul DrawerContent via a
        portal-container context so they stay inside the Radix modal layer
        instead of inheriting body pointer-events: none
      - Provide an in-memory localStorage/sessionStorage in test-setup when the
        Node 25+ global accessor resolves to undefined and shadows jsdom
      - Add regression tests for popups rendered inside and outside the drawer

    • refactor(json): route JSON helpers through a host-injectable codec · 7bbe85bc
      `common/json.go` and `relaykit/relayconvert/kitutil/json.go` were two
      hard-wired copies of the same encoding/json wrapper, so swapping the JSON
      engine required editing both modules.
      
      - kitutil defines a `Codec` interface with a standard-library default and
        a `SetCodec` hook, mirroring the existing SetLogging host hook; every
        kitutil JSON helper and relaykit DTO (un)marshal method goes through it
      - `common/json.go` forwards to kitutil and injects `hostJSONCodec` from
        init() so tests run on the same engine as production; swapping the
        engine now touches only this type in the root module
      - route the remaining direct encoding/json calls inside relaykit
        (dto/values.go, responses stream validation) through kitutil
      - add a codec routing test and a host codec conformance test locking the
        encoding semantics the DTOs depend on
      
      Direct encoding/json call sites in the root module are left for a
      separate cleanup.

    • fix(relay): preserve Kimi K3 dynamic tool loading messages · 6e10f9bc
      Kimi K3 injects tools mid-conversation via a system message that carries
      a `tools` array. `dto.Message` had no such field, so the tools were
      silently dropped during the parse/re-marshal round trip and the upstream
      rejected the request with `'tool_choice'='required' requires a 'tools'
      field`.
      
      - add `Message.Tools` (json.RawMessage passthrough)
      - omit the `content` key only for tool-loading messages with nil content,
        as Kimi rejects `tools` next to `content`; all other messages keep
        emitting `"content": null`
      - count message-level tools in token estimation
      - skip tool-loading messages in channel system prompt injection and make
        the compatible handler reuse applySystemPromptIfNeeded
      - add kimi-k3 to the moonshot model list

    • feat(ali): support wan3.0 all-in-one video models · 3b465226
      * feat(ali): support wan3.0 all-in-one video models
      
      Extend the Alibaba task plugin for wan3.0-video / wan3.0-video-prime
      using DashScope media, resolution/ratio, duration rules, and billing ratios.
      
      * fix(ali): make wan3.0 smart duration billable and alias-safe
      
      Review fixes on top of #7240 (qiuliw):
      
      - duration -1 never reached the plugin: the host rejects negative
        canonical duration/seconds facts before any hook runs, on every
        entry point. Decoders now normalize -1 into an auto_duration marker;
        convert emits -1 upstream and bills 30s up front; non-wan3.0 models
        reject the marker instead of silently defaulting to 5s.
      - extractUsageOnComplete read output.duration/output.resolution, but
        wan3.0 reports usage.output_video_duration and numeric usage.SR, so
        smart-duration and resolution settlement never reconciled. Read the
        usage block first, keep the legacy output fields as fallback.
      - convert keyed default resolution on the client model name, so a
        channel-mapped alias fell to 720P while the direct request got 1080P.
        Every model-shaped decision in convert now uses ctx.upstreamModel.
      - Unknown wan3.0 size values were silently coerced to 1080P; reject them.
      - Image-only openai_responses input was accepted for every model,
        regressing t2v models into pre-consume then upstream rejection.
        Restore the guard and allow image-only for i2v and wan3.0 only.
      - Native passthrough dropped wan3.0 parameters (ratio, audio) unless
        media was present; forward them via metadata for wan3.0.
      - Hoist the triplicated size-to-resolution map; add wan3.0 contract tests.

      Introduce a unified model management experience: catalog metadata
      validation, vendor management, batch delete with channel/pricing
      cleanup, model pricing snapshot editing with optimistic concurrency,
      and an upstream ratio-sync flow with price cells. Move configuration
      into dedicated pricing config/metadata-sync/vendor-management backend
      services and add audit records for model/vendor/pricing mutations.
      
      Rework the models page around vendors and model connections, add
      model-pricing and vendor-management dialogs, and replace the shared
      Select usages with the Combobox component across subscriptions,
      plugins, OAuth presets, audit filters, and settings. Add the model
      pricing panel and verify behavior with focused tests.

    • fix(relay): apply model-specific OpenAI chat capabilities (#7211) · 49ec4696
      * fix(relay): treat gpt-5 and later generations alike for max_completion_tokens
      
      IsOpenAIGPT5Model matched on the literal prefix "gpt-5", so gpt-6-astra
      (and every generation after it) fell through the gpt-5 request rules:
      max_tokens was forwarded as-is and the provider rejected it with
      "Unsupported parameter: 'max_tokens' is not supported with this model.
      Use 'max_completion_tokens' instead." The same gap left temperature,
      top_p and logprobs untouched, each of which the provider also rejects,
      and made the channel test button report a 400 for a healthy deployment.
      
      Match on the major version instead (gpt-<n>... with n >= 5). Callers are
      unchanged: ConvertOpenAIRequest, GetSystemRoleName, buildTestRequest and
      the health check all go through this one helper. buildTestRequest now
      sends max_completion_tokens for these models directly instead of relying
      on the later conversion. gpt-4.1, gpt-4o, gpt-oss, gpt-image and
      gpt-realtime names still do not match.
      
      Verified against Azure OpenAI gpt-6-astra (2026-09-03): with the old
      prefix max_tokens / temperature / top_p / logprobs each returned 400,
      while gpt-5.6-luna with the same payload returned 200.

    • feat(relay): explicit @ model modifiers and canonical billing identity · 7c044d7c
      Model-name post-processing is rebuilt around an explicit trailing
      @key:value modifier syntax (thinking/effort/temperature/topp) that
      overrides request fields, survives model mapping, and records
      conversion diagnostics on the consume log.
      
      - Legacy naked aliases (-thinking, -nothinking, -thinking-<budget>,
        effort tails) now parse only for positively matched families
        (gpt-*/o-series, claude-*, gemini-*, incl. vendor/ namespaces);
        names like qwen-max stay opaque. EffortTailModelIDs remains the
        escape hatch for real in-family IDs such as gpt-5.1-codex-max.
      - Billing identity resolves once in ModelPriceHelper via a ladder:
        configured request name first (legacy wildcard entries intact), then
        canonical billing names rebuilt from parsed intent
        (base@effort:E@thinking:S, then base@thinking:S; order, duplicates,
        and budget values are irrelevant; temperature/topp never priced),
        then base. Routing and token limits fall back through
        RoutingMatchModelName; pricing lookups stay wildcard-only.
      - Pass-through stays byte-identical: modifiers and aliases are neither
        parsed nor validated there and forward verbatim for the upstream
        (or a chained gateway) to interpret.
      - Unknown modifier keys and invalid known-key values are rejected with
        400; models whose real names contain @tag:value are exempted via the
        thinking-suffix blacklist, which now supports re:-prefixed Go regex
        entries.
      - Claude reasoning render coerces unsupported combinations (disable,
        adaptive, budgets) with warning diagnostics instead of erroring;
        native-protocol requests without host syntax pass through untouched.
      
      BREAKING(openrouter): drop the host-invented "-thinking" model-name
      alias (added in 4f6d16e3) that trimmed any *-thinking model on
      OpenRouter channels and injected reasoning.enabled. It matched too
      broadly and mangled real model IDs such as kimi-k2-thinking.
      Migration: use some-model@thinking:on, or keep the old public name via
      a channel model mapping {"some-model-thinking": "some-model@thinking:on"}.
      Claude/Gemini family aliases (incl. anthropic/claude-*-thinking) keep
      working via the family whitelist.

    • fix(task): explain 503 when a plugin-claimed model has no channel · 32c26192
      A model declared by a task plugin is served only by that plugin's channels.
      When the claiming plugin has no enabled channel in the request group, the
      distributor answered with the generic "no available channel" text, which hides
      the actual cause and led operators to expect channel model_mapping on another
      plugin's channel to take over (#7185). That expectation is not supported:
      plugin declarations own model names statically, and channel availability must
      not silently reassign ownership at request time. The supported fixes are the
      existing operator tools, disabling the factory plugin per key or overriding it.
      
      Both no-channel 503 sites in the distributor now route through
      noAvailableChannelMessage. When the request is pinned to a task plugin, the
      message names the claiming plugin and points to disabling or overriding it;
      non-plugin requests keep the generic message. Added in en, zh-CN, zh-TW.

    • feat(task): give polling hooks a real query context, host HTTP classification,… · 9df450fe
      feat(task): give polling hooks a real query context, host HTTP classification, and bounded poll failures
      
      Plugin polling hooks previously ran against a hollow context: parseTaskResult
      and parseBatchResult received {} / nil, buildQueryRequest received a
      {task_id, action} map under the misleading name requestBody, and batch hooks
      saw only bare task ids. The per-task poller also never looked at the upstream
      HTTP status, and every built-in plugin papered over unrecognized bodies with
      `|| "IN_PROGRESS"`, so a 404, a revoked key, or a shape the plugin did not
      know would sit in IN_PROGRESS for the full 24h TASK_TIMEOUT_MINUTES while
      holding the user's pre-charged quota.
      
      Contract (docs/plugin-api v1.d.ts, v1.md, v1.schema.json):
      - TaskQueryContext is declared separately from DriverContext and rebuilt from
        the persisted Task row: taskId, publicTaskId, action, model, upstreamModel,
        baseUrl, apiKey, authHeader, auth, data, state. Query-side requestBody is
        removed; the original request is not persisted and hooks that need a
        request-derived value must save it into state at submit time.
      - parseTaskResult / parseBatchResult receive a third {status, headers}
        argument. Batch hooks receive tasks[] with one TaskQueryContext per task.
      - NormalizedTaskResult accepts status "UNKNOWN" meaning "I do not recognize
        this body". Falling back to IN_PROGRESS for unknown shapes is forbidden;
        `plugin lint` warns on the literal.
      - parseSubmitResponse / parseTaskResult / parseBatchResult may return `state`.
        Task.Data remains a per-round snapshot overwritten on every valid parse;
        state is plugin-owned, persisted in TaskPrivateData.PluginState, preserved
        when a hook omits it, byte-capped like taskData, and never exposed through
        presenter views.
      
      Host (service/task_polling.go, relay/channel/task/jsplugin/adaptor.go):
      - TaskPollingAdaptor / BatchTaskPollingAdaptor take *model.Task and the
        *http.Response so the adaptor can build the full context; jsplugin is the
        only implementation.
      - HTTP classification before the plugin sees the body: 2xx -> plugin;
        404/410 -> FAILURE and refund; 401/403 -> poll failure plus a channel-scoped
        warning, no auto-disable; 429/5xx/transport -> poll failure; other 4xx ->
        plugin with the status visible, counted as unrecognized if the plugin still
        reports a non-terminal state.
      - TaskPrivateData.PollFailures counts consecutive poll failures (transient
        HTTP, auth, transport, hook error, UNKNOWN). It is persisted through the
        existing UpdateWithStatus CAS so a concurrent terminal transition on another
        instance is never clobbered, and reset on any valid 2xx non-terminal parse.
        Reaching TASK_POLL_MAX_FAILURES (default 20, <= 0 disables) fails the task
        with the last classification and HTTP code in fail_reason and runs the
        existing settle/refund chain exactly once. sweepTimedOutTasks and its
        1440-minute default are unchanged as the outer backstop.
      - Unrecognized bodies are logged at WARN with a bounded redacted copy since
        Task.Data is intentionally not overwritten on that path.
      
      Plugins (all ten bumped one patch version):
      - jimeng persists the outbound req_key in state and reads it back in
        buildQueryRequest, replacing dead reads of ctx.data / ctx.requestBody that
        never resolved.
      - sunoapi batch hooks read tasks[] instead of the removed requestBody.
      - hailuo treats base_resp.status_code != 0 as FAILURE before the status table.
      - kling, vidu, sora, alibaba, doubao, hailuo, jimeng return UNKNOWN with the
        raw upstream status in reason on table miss.
      - google and vertex-ai treat a missing `done` as in-progress: Google
        long-running operations omit proto3 default fields, so a running Veo
        operation has no `done` key at all. Only a body without an operation name is
        UNKNOWN. plugins/veo_poll_test.go locks this so the poll-failure cutoff can
        never fail a rendering Veo task.
      
      Tests cover the classification table end to end against a real DB (404
      immediate refund, 429xN refund, 401 increments without status change, 2xx
      reset, UNKNOWN increments, state preserved vs replaced, PollFailures survives
      the CAS write), the query-context shape, UNKNOWN on unrecognized bodies, and
      the absence of PluginState/PollFailures from TaskView. Controller tests derive
      the kling factory version from the embedded manifest instead of hardcoding it.

      Weak comparison ignores W/ on both operands, so etagMatches now strips it from
      the served validator as well as from each candidate. Stripping only the
      candidate would make a weak served validator match nothing and silently
      disable every 304.
      
      Vary: Accept-Encoding stays. Weakening the validator makes revalidation
      correct, but it does not separate the two encodings in a shared cache.

      * feat(plugin): add MiniMax-H3 /v2 video generation to the hailuo task plugin
      
      MiniMax-H3 speaks a different contract from the other Hailuo models, so the
      hailuo task plugin now branches on the upstream model instead of adding a Go
      adaptor:
      
      - submit builds /v2/video_generation with a multimodal `content` array
        (text, first/last frame images, reference video/audio, or a full
        `metadata.content` passthrough), an explicit `ratio`, and 768P/2K
        resolutions; `metadata.callback_url` and `metadata.aigc_watermark` pass
        through
      - query uses /v2/query/video_generation/{task_id} and parses the
        `{"task": {...}}` envelope, falling back to the /v1 shapes for every other
        model
      - the /v2 result is a public CDN URL, so its artifact is proxied
        credentialless instead of through /v1/files/download
      - request bounds (duration 4-15, resolution 768P/2K, ratio whitelist, at most
        2 frame images and 9/3/3 reference images/videos/audios) are enforced while
        the request body is built, which the host runs during validation, so an
        out-of-range duration is rejected with a 400 before it can become a billing
        multiplier
      - duration and resolution are reported as usage facts only. Like the rest of
        this plugin, extractUsage returns no billing ratios, so per-call pricing is
        flat and 2K/duration pricing is expressed through the model's tiered billing
        expression over those facts.
      
      Query hooks are driver hooks and are documented to receive `ctx.model` and
      `ctx.upstreamModel`, but polling has no relay info and never populated them.
      The polling and realtime-fetch call sites now carry the persisted task model
      properties and the plugin adaptor maps them onto the query context, with
      `upstreamModel` falling back to the origin name for tasks submitted without a
      channel mapping.

    • fix(relay): follow-up billing integrity and conversion completions (#7170) · bbd97446
      Deferred follow-ups from the relaykit-tools review cycle, verified by
      live end-to-end billing tests:
      
      - billing: normalize Gemini modality keys consistently between stream
        merge and settlement (case/whitespace variants no longer drop
        independent audio/image pricing) and sum duplicate modality entries
        on both paths
      - billing: sync legacy flat Claude cache-creation fields from the
        CacheCreation sub-object (including zeroing) and fall back to flat
        fields only when the snapshot never carried a sub-object, closing a
        stale 1h-cache overcharge path in cascaded deployments
      - relay: move Chat-to-Claude and Chat-to-Gemini stream conversion state
        from gin.Context onto RelayInfo and reset it with SendResponseCount in
        InitChannelMeta, so channel retries start clean while per-request
        state (stream error collection, conversion diagnostics, channel
        chain, billing accumulators) survives
      - relay: Claude channel now serves Gemini-format clients (request via
        registry conversion, response and stream composed through the Chat
        pivot), removing the last unimplemented conversion direction
      - relaykit: recognize legacy pseudo tool names (googleSearch,
        codeExecution, urlContext) in the toolconv decode stage and drop the
        string-matching bypass in the Chat-to-Gemini converter; native Gemini
        tool output is restored and non-Gemini targets follow standard loss
        diagnostics
      - relaykit: attach upstream Gemini usage (with billing_usage sidecar)
        to intermediate stream chunks so converted Claude streams report
        upstream truth from message_start, and preserve the sidecar through
        Claude stream usage merges; billing settlement unchanged
      - billing: clamp negative Total-Prompt completion derivation, OR the
        Estimated flag across cross-dialect snapshot replacement, and fill
        canonical OpenAI prompt details via field-wise merge
