root c1e7c5e90c feat(publish): add tenant publish management with desktop deep-link
Expose tenant-authenticated publish task list and retry endpoints so the
admin web can show desktop publish state without an Electron bridge, and
register a `shengxintui://` deep-link so the page can hand off to the
desktop client workbench.

root 1ba29b9a09 feat(desktop): isolate platform accounts per desktop client
Frontend CI / Frontend (push) Successful in 3m4s
Backend CI / Backend (push) Successful in 14m24s
Scope desktop media accounts by the authenticated desktop client_id so
the same user logging in from Mac and Windows no longer sees a shared
account list. The list, identity lookup, upsert, patch, tombstone and
async health sink paths now all require matching client_id, and the
active uniqueness index moves from (workspace, platform, uid) to
(workspace, client, platform, uid).

Also strengthen the desktop client_id seed: when the OS machine id is
unavailable, fall back to a hashed fingerprint of stable hardware MAC
addresses before the random installation id, so the same hardware
keeps the same client across reinstalls.

root 618399f86d feat(server): hot-reload config store and reloadable infra clients
- Replace single Load() with a watching Store that re-reads config files
  (and config.local.yaml) and fans out a ReloadEvent with a per-field diff
  so consumers can decide whether the change is hot-applicable or requires
  a process restart.
- Wrap llm, retrieval, vector store, and object storage clients in
  Reloadable* shells so the bootstrap can swap their underlying impls when
  config changes without re-instantiating handlers.
- Make jwt.Manager and ops TokenIssuer mutable under a lock so secrets and
  TTLs can be rotated live; thread default plan code through a setter on
  the ops AdminUserService.
- Wire ConfigStore through bootstrap and every cmd/main.go, scheduler /
  worker / tenant-api / ops-api start the watcher; services and handlers
  take a config.Provider so they always read current values for things
  like generation.stream_enabled, scheduler dispatch, retrieval, etc.
- Switch shared/config decoding off viper to a Kratos-derived runtime
  package so env placeholders (\${VAR:default}) resolve consistently and
  the same source machinery powers both the loader and the watcher.

root b345ee26e4 feat(monitoring): match citations by canonical link and scope summary by brand/keyword/platform/date
Replace the domain+title fuzzy alias scoring with a canonical
candidate-key index built from published-link aliases — only exact
matches now resolve to a SaaS source, eliminating false positives
across articles sharing a host (e.g. m.163.com vs www.163.com).

Surface the summary scoping that already existed on loadCitationRanking
/ loadCitedArticles by accepting brand_id, keyword_id, ai_platform_id
and business_date on CitationSummary, plumbing them through the handler
and admin tracking view.

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.

Wire LoginGuard into tenant-api and ops-api login flows: acquire a

attempt to drive lockouts, and clear counters on success. Tenant-api
now also forwards the request IP into the service so per-IP and

root 9bb7144593 refactor(kol-admin): move subscription admin endpoints from tenant-api to ops-api
Approving / manually binding / revoking KOL subscriptions belonged to the
operations console, not the tenant-admin role on tenant-api. Add a fresh
KolSubscriptionService + repository + handlers under the ops module with
its own list/manual-bind/approve/revoke routes, wire a Redis-backed cache
into ops-api so admin actions can invalidate tenant prompt caches, and
delete the tenant-side admin service/handler now that ops-web owns the UI.

without going through the marketplace approval flow. Reject self-subscribe

Response. The admin-web KOL workspace gets 订阅自己 / 取消订阅 entries with

/title/outline, and KOL prompt generate/optimize. Pending reservations
are reconciled when the kol-assist worker and template-assist tasks
finish or fail, so points refund automatically on errors. Workspace now

root 7605890a14 refactor(server/monitoring): route monitor desktop tasks by account presence
Daily monitoring tasks were pinned to a single primary client. If that
client went offline the task wedged even when another desktop client of
the same workspace was online and bound to the same account. Drop the
primary-client constraint on the materialized collect rows, and instead
pick a target per-platform from live account/client presence in Redis,
falling back to the DB client_id when the desktop client is still flagged
online. Desktop task lease for kind=monitor now matches by account
ownership in addition to target_client_id, so any client owning the
account can drain the queue.

root 051976e4a9 feat(server/desktop): ingest desktop account health reports
Add a POST /desktop/accounts/health-reports endpoint that buffers reports in
Redis, dedupes via signature, and publishes change events to a new
desktop.account.health RabbitMQ queue. A sink worker drains the queue, and
the account service overlays runtime health onto database health when serving
desktop accounts. Publish job creation now consults runtime health so a stale
DB row no longer blocks publishing once the desktop client reports it healthy.

root ff86933c24 feat(monitoring): generate daily tasks and optimize heartbeat writes
Adds a MonitoringDailyTaskWorker that materializes and dispatches
daily collect tasks from active subscription/desktop-client state,
with per-run atomic metrics and a Prometheus collector. Dashboard
and question-detail APIs now surface a platform_authorization_status
so the UI can distinguish no-desktop-client, no-authorized-platforms,
and authorized states; quota/access-state lookups resolve by request
workspace instead of tenant.

Hardens heartbeat: a desktop_client_primary_leases table gives
per-(tenant, workspace) sticky primary selection, read-mostly lease
resolution avoids a per-heartbeat transaction, and unchanged platform
access reports skip snapshot upserts outside a 10-minute refresh
window. Adds heartbeat primary/snapshot metrics exposed via
token-protected tenant-api /api/internal/metrics endpoints plus
Prometheus. Monitoring quota seed is removed from dev-seed since
daily plans now derive from desktop bindings, and the projection
uses the canonical six-platform catalog so platforms with zero
samples still render.

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.
