root fb166fa9fe feat(monitoring): attribute SaaS citations by registrable domain
Persist host/registrable_domain/site_key on monitoring article URL
aliases, populate them on desktop-publish completion, and use them in
the citation pipeline to count how often SaaS-published content
appears as a citation source. Expose a /citation-summary endpoint with
a 7/30-day window switch and surface the new source-share metrics in
the tracking dashboard.

root 6e6e19cccb feat(schedule-tasks): support auto-publish via media accounts
Replace the legacy target_platform string on schedule tasks with a
workspace-aware auto-publish payload (auto_publish + publish_account_ids
JSONB + cover_asset_url + cover_image_asset_id) and migrate the schema,
sqlc queries, generated models, domain struct, ScheduleTaskService DTOs,
and dispatch worker to round-trip the new fields. PromptRuleGeneration
gains a WithPublishJobService hook so executeGeneration can enqueue an
auto-publish job once the article is ready, and worker-generate wires
the publish-job service in. On the admin-web side, extract
PublishArticleModal's account-card builders into a shared
publish-account-cards module, rebuild GenerateTaskDrawer's schedule
mode around account selection plus a CoverPickerModal, and surface the
new "auto publish" column on ScheduleTaskTab. Shared types and i18n
strings cover the new fields.

root c9267d2fae feat(auth): block disabled user accounts at the subscription guard
RequireActiveTenantSubscription now optionally takes an AuthRepository
and rejects the request with 40311/user_disabled when the actor's user
row is anything other than active. Wire the repo through the tenant
router, surface the new error code in admin-web's
membershipBlockedErrors set, persist a "disabled" membership status when
markStoredMembershipBlocked sees user_disabled, and add localized copy
on the blocked screen and shell membership banner.

Add /kol/manage/packages/:id/self-subscription POST/DELETE on the tenant
side so a KOL can grant themselves access to their own published package
without going through the marketplace approval flow. Reject self-subscribe
through the marketplace with a clear error, expose owned_by_current_tenant
on package responses, and surface a self_subscription block on KolPackage
Response. The admin-web KOL workspace gets 订阅自己 / 取消订阅 entries with
matching messaging in the marketplace detail view.

root 59ad14ef2c feat(desktop/account-health): treat active/expiring_soon probes as live and dedupe in-flight checks
Why: avoid showing accounts as not-live during stale-window probes; keep publish gating consistent with runtime view.

- collapse FIRST_PROBE window so initial probe runs immediately
- skip due-probe selection when a probe is already queued/in-flight
- mirror auth-state→health projection on both client report and tenant ingest paths

root 62b824520c feat(admin-web/auth): support phone-or-email login and dim shell on expiry
Login form takes a phone-or-email identifier; user info now exposes phone
so the shell can fall back through name → phone → email. When membership
expires, the app stays on the current route but renders a minimal blocked
state in the shell instead of redirecting to a dedicated page; an Axios
interceptor flips the local session into the blocked state when the API
returns trial/subscription errors.

- drop brand_time_buckets and sparkline/coverage UI; dashboard now returns a single day
- compute mention rate from total actual samples instead of averaging per-platform rates
- canonicalize ai_platform_id across services and aggregate platform-overview snapshots

- keep Kimi citations panel-only; still store raw search_results for audit
- render linked [n] inline citations for qwen/yuanbao answers with scroll-to-source behavior
- restrict立即采集 to today's business date with a clear i18n hint

Replace SSE /desktop/events with priority AMQP dispatch for monitoring
runs, and add phase1/phase2 infrastructure so desktop workers can lease,

- Add monitoring collect outbox worker and phase2 desktop task fields
- Add /desktop/monitoring/tasks/{lease,resume,result,skip,cancel} routes
- Introduce execution-devtools and network-observer on desktop runtime
- Refactor runtime-controller, LoginView, and doubao adapter for the new flow

root 9fa091c150 feat(desktop): push publish tasks via AMQP topic dispatch WebSocket
Introduce a desktop.task.dispatch topic exchange with per-client routing
keys. Tenant-api publishes a task_available frame keyed by target client
ID when a publish job is created; every instance binds its own transient
queue and forwards to the matching WebSocket (/api/desktop/dispatch) it
owns. Desktop-client now prefers this push channel and only falls back
to HTTP /lease polling when the socket is down. Also drop admin-web
monitoring-plugin remnants and scope the publish modal account list to
publish platforms.

- Relaxed authentication requirements for monitor tasks, allowing anonymous execution for certain AI platforms.
- Enhanced the generic AI platform detection to include Qwen-specific logic, ensuring accurate session identification.
- Modified the monitoring dashboard to include runtime state indicating if the current user's desktop client is online.
- Updated various files including `account-binder.ts`, `runtime-controller.ts`, and `monitoring_service.go` to support new features and improvements.

root dc68ad044c refactor(publish): collapse pending_review/unknown task states into failed
Treat ambiguous terminal states as failures end-to-end: server
normalizes unknown desktop task completions and views to failed, drops
the pending_review aggregate branch, and remaps pending_review to
failed in publish record conversion. admin-web removes the
pending_review status option from article list filters, pushes
pending_review through the failed tone, and folds lingering
publishing/pending entries under the publishing bucket. desktop-client
relabels unknown as 发送失败 in PublishManagement/TasksView, rewrites
the scaffold adapter result to a proper failed error envelope, and
sanitises legacy scaffold-only error messages to a user-friendly note.

Plan 0 (workspaces): add workspaces + workspace_memberships schema, extend
JWT/Actor/claims with primary_workspace_id, seed default workspace per tenant,
thread workspace_id through tenant monitoring quota.

Plan A (desktop skeleton): new Electron app (apps/desktop-client) with main/
preload/renderer, shared Vue component package (packages/ui-shared), and server
surface — desktop client registration + token rotation + heartbeat, SSE task
event stream, desktop accounts/tasks/content handlers, publish job endpoint,
and supporting repositories, services, sqlc queries, and migrations.

Hard cutover per plan: remove browser-extension monitoring callback endpoints,
stub legacy media API in admin-web, and delete monitoring_callback_handler.go.

- Add POST /kol/manage/assist/stream as a Server-Sent Events endpoint

  streamAssist helper on kolManageApi that reports ApiClientError with
  the server's error envelope.
- Stream generated content live in KolPromptEditor and KolGenerateView,

  generator page layout.
- Add KolAssistStreamEvent to shared types.
