Group pricing (rate multiplier, peak windows, per-user overrides) and
account cost (accounts.rate_multiplier) already live side by side, but
nothing stops the scheduler from handing a request to an account whose
cost multiplier exceeds what the group's pricing can profitably serve.
Add an opt-in per-group profit gate that filters scheduling candidates
by a margin rule, while ordering, scoring, stickiness and breakers keep
working unchanged among qualified accounts.
Admission rule: an account qualifies iff U <= D * (1 - min_margin -
safety_buffer) within a small relative epsilon, where U is
accounts.rate_multiplier (0 is legal; missing/negative/NaN/Inf are
conservatively rejected as invalid) and D is the requester's effective
downstream multiplier (user-group override ?? group default, times the
group peak factor) frozen at the request's pricing instant.
- groups gain profit_control_enabled / profit_min_margin /
profit_safety_buffer (migration 191); the durable auth-cache
invalidation trigger additionally watches the profit and pricing
columns (migration 192) so out-of-band group edits cannot leave
stale auth snapshots; GetByKeyForAuth explicitly projects the new
columns and the API-key auth snapshot version is bumped to force a
refresh of pre-existing snapshots
- request-level pricing instant: token entry points install pricingAt
into ctx; the profit threshold D and the RecordUsage peak factor
read the same instant, so one request never changes price mid-flight
across waits/retries/failover (media and unwired paths keep the
existing record-time semantics)
- the gate covers token requests on openai, anthropic, gemini, grok
and antigravity groups: OpenAI-family handlers via
WithOpenAIRequestPricingContext (responses incl. WS bridge, chat
completions, messages, embeddings, alpha search), the shared gateway
via WithGatewayTokenRequestPricing (messages, chat completions,
responses, gemini model actions); composite groups cannot enable it
directly; image/video/models/usage/count_tokens stay ungated and an
explicit image-generation intent suppresses the gate end to end
- post-slot recheck: after a slot is acquired the account is re-read
via SchedulerSnapshotService.GetAccount (scheduler cache, then DB;
only when both fail the check fails open with WARN + metric); a
vetoed account releases its slot and joins the request's exclusion
set for reselection; sticky bindings are written only after the
final check passes, and an over-threshold sticky account is skipped,
not deleted, so it comes back once its rate recovers
- sticky-session cache contract: GatewayCache.GetSessionAccountID now
returns ErrStickySessionNotFound on a miss (mapped from redis.Nil in
the repository implementation, mirroring ErrRefreshTokenNotFound) so
the profit sticky path can distinguish "no binding yet" from a real
read failure without importing the cache driver in service code
- cross-group re-entry (composite parent -> member group) resolves the
gate against the member group and clears a stale parent gate instead
of letting a foreign threshold veto accounts
- per-platform/group activity counters (installs, threshold vetoes,
invalid-rate vetoes, refresh failures) for observability
- admin UI: profit-control section on the five platforms' group forms
with percent input, validation and platform-switch reset; group
create/update/duplicate normalize and validate the config at a
single choke point
- cmd/profit-preview: offline what-if tool that replays the production
admission semantics over an exported config/account/override/model
dump, reports per-model admitted-account counts under the default
and the worst-case (lowest user override) D, and surfaces probe-sync
staleness as warnings without affecting admission
Tests: service unit coverage for gate resolution/veto/threshold
epsilon/pricing instant/suppress marker/scheduler filtering and
post-slot recheck (incl. -race on the profit surface), unit-tagged
handler slot-recheck and capability-mapping regressions, sqlmock and
real-PostgreSQL integration regressions for the GetByKeyForAuth
projection and the migration-192 trigger watch list, API contract
update, and frontend specs for the five-platform form helpers.
Problem:
Upstream channels can reject monitor probes based on client fingerprint
(e.g. "only Claude Code clients allowed"). The monitor had no way to
customize the outgoing request to bypass such restrictions.
Solution:
Introduce reusable request templates that carry extra_headers plus an
optional body override; monitors reference a template and receive a
snapshot copy on apply. Template edits do NOT auto-propagate — users
must click "apply to associated monitors" to refresh snapshots, so a
bad template edit cannot instantly break all production monitors.
Data model (migration 112):
- channel_monitor_request_templates: id, name, provider, description,
extra_headers jsonb, body_override_mode ('off'|'merge'|'replace'),
body_override jsonb. Unique (provider, name).
- channel_monitors: +template_id (FK, ON DELETE SET NULL), +extra_headers,
+body_override_mode, +body_override (the three runtime snapshot fields).
Checker (channel_monitor_checker.go):
- callProvider + runCheckForModel accept a CheckOptions carrying the
snapshot fields. mergeHeaders applies user headers on top of adapter
defaults (forbidden list: Host / Content-Length / Transfer-Encoding /
Connection / Content-Encoding).
- buildRequestBody:
off -> adapter default body
merge -> shallow-merge over default; per-provider deny list
(model/messages/contents) protects the challenge contract
replace -> user body verbatim
- Replace mode skips challenge validation; instead HTTP 2xx + non-empty
extracted response text = operational, empty = failed.
- 4 new unit tests cover all three modes + replace/empty-response case.
Admin API:
- /admin/channel-monitor-templates CRUD + /:id/apply (overwrite snapshot
on all template_id=id monitors, returns affected count).
- channel_monitor request/response DTOs gain the 4 new fields.
Frontend:
- channelMonitorTemplate.ts API client.
- MonitorAdvancedRequestConfig.vue shared component for headers textarea
+ body mode radio + body JSON editor; used by both template and monitor
forms.
- MonitorTemplateManagerDialog.vue: provider tabs, list/create/edit/
delete/apply, live "associated monitors" count per row.
- MonitorFiltersBar: new 模板管理 button next to 新增监控.
- MonitorFormDialog: collapsible 高级 section with template dropdown
(filtered by form.provider, clears on provider change) + embedded
AdvancedRequestConfig. Picking a template copies its fields into the
form (snapshot semantics mirrored on the client).
- i18n zh/en entries for all new copy.
chore: bump version to 0.1.114.32
Add a full payment and subscription system supporting EasyPay (Alipay/WeChat),
Stripe, and direct Alipay/WeChat Pay providers with multi-instance load balancing.
Implements announcements end-to-end (admin CRUD + read status, user list + mark read) with OR-of-AND targeting. Also breaks the ent<->service import cycle by moving schema-facing constants/targeting into a new domain package.
Add a flexible user attribute system that allows admins to define
custom fields for users (text, textarea, number, email, url, date,
select, multi_select types).
- Add Ent schemas for UserAttributeDefinition and UserAttributeValue
- Add service layer with validation logic
- Add repository layer with batch operations support
- Add admin API endpoints for CRUD and reorder operations
- Add batch API for loading attribute values for multiple users
- Add database migration (018_user_attributes.sql)
