将 vansour/sub2api#1555 的 OpenAI compact 能力建模手工移植到当前 main：账号
级 compact 状态/auto-force_on-force_off 模式、compact-only 模型映射、调度器
tier 分层（已支持 > 未知 > 已知不支持）、管理后台 compact 主动探测，以及对应
i18n/状态徽章。普通 /responses 流量行为不变，无数据库迁移。

- Change overall status logic: >50% failed = UNAVAILABLE, any failed
  or degraded = DEGRADED, all ok = OPERATIONAL
- Extract useAutoRefresh composable with localStorage persistence
- Create AutoRefreshButton dropdown component (reusable)
- Integrate auto-refresh into channel status page via MonitorHero

and cosmetic changes that were brought in by the release sync commit.
Keep only channel-monitor related improvements:
- PublicSettingsInjectionPayload named struct with drift test
- ChannelMonitorRunner graceful shutdown in wire
- image_output_price in SupportedModelChip
- Simplified buildSelfNavItems in AppSidebar
- Gateway WARN logs for 503 branches

- Extract PublicSettingsInjectionPayload named struct with drift test
- Add channel_monitor_default_interval_seconds to SSR injection

- Clean up fork-only features (sora, claude max simulation, client affinity)
- Remove ~320 obsolete i18n keys
- Add codexUsage utility, WechatServiceButton, BulkEditAccountModal
- Tidy go.sum

P0:
- rpm_override 嵌入 Auth Cache Snapshot，消除每请求 DB 查询 (snapshot v6→v7)
- 429 RPM 响应返回 Retry-After 头（当前分钟剩余秒数）

P1:
- ClearAll 按钮直连 DELETE API，带 loading 防重复
- 新增 GET /admin/users/:id/rpm-status 管理员 RPM 用量查询端点

优化:
- checkRPM 从级联互斥改为并行取最严，user.rpm_limit 作为全局硬上限始终生效
- Override/Group 变更后自动失效 auth cache
- fail-open 语义不变，Redis 故障不阻塞业务

Channel Monitor card now links to 渠道管理 > 渠道监控 and the Available
Channels card links to 渠道管理 > 渠道定价 so admins know where to go
after flipping the switch.

- 描述独立成列：渠道名与描述各占一列，均用 rowspan 纵向合并
- 渠道名单元格 text-center + align-middle，合并后视觉居中
- table-fixed：给 name/description/platform 显式宽度，groups 和
  supported_models 在剩余空间均分。支持模型列此前在 table-auto 下
  不会换行导致横向溢出遮挡（反馈截图），加 table-fixed 后天然 flex-wrap
- i18n 增加 availableChannels.columns.description（zh/en）

Pricing popover:
- Teleport to body + fixed-position re-measuring on hover/scroll/resize so it
  escapes the card's overflow-hidden clip that was chopping off the lower
  half of the panel.
- Header + border adopt the platform theme via platformBorderClass /
  platformBadgeLightClass so each model card reads at a glance.

Accessible groups:
- Backend AvailableGroupRef / user DTO now expose subscription_type,
  rate_multiplier and is_exclusive. User-specific rates continue to come
  from /groups/rates (same pattern as the API keys page).
- Table renders groups through the shared GroupBadge, which already deepens
  subscription-type colors and shows default vs custom rate as
  <s>default</s> <b>custom</b>.
- Exclusive groups are labelled with a purple shield row, public groups
  with a grey globe row so admins and users can tell at a glance which
  groups they got via explicit grant vs. public access.

i18n keys for exclusive / public / their tooltips added to zh + en.

Switch the user-facing 'Available Channels' view from "one row per
platform" to "one channel row-group with N platform sections".

Backend: userAvailableChannel now holds Platforms []section instead
of being exploded. buildPlatformSections replaces
explodeChannelByPlatform with the same per-platform grouping logic.

Frontend: drop the DataTable wrapper for this view and write a
four-column grid table (渠道名 / 平台 / 分组 / 支持模型) where the
channel name only renders on the first platform row of each channel —
visual rowspan without hacking DataTable.

- api/channels.ts: UserChannelPlatformSection + platforms[]
- AvailableChannelsTable: rewritten as native grid (header + per-
  channel section with hover row highlight)
- AvailableChannelsView: search now filters platforms sub-array;
  channel-name / description hits still keep the whole channel
- i18n: add availableChannels.columns.platform (zh/en)

Follow-up to the available-channels review pass. No behavior change for
end users; tightens internals based on three independent code reviews.

Backend
- service/channel.go: collapse buildPricingLookup + pricedNamesFor
  into a single platformPricingIndex (byLower + originalCase + ordered
  names), built once per SupportedModels call. Fixes a casing-
  consistency bug where the same logical model appeared with mapping
  case in the exact branch but pricing case in the wildcard branch —
  pricing's original case now wins everywhere.
- service/channel.go: doc that a mapping key of just "*" expands to
  every priced model on the platform (intentional "passthrough all").
- service/channel_available.go: normalize empty BillingModelSource to
  channel_mapped at construction time, removing the same fallback
  duplicated in the admin DTO mapper and the admin Vue template.
- handler/admin/available_channel_handler.go: unexport
  availableChannelToAdminResponse (same-package usage only); mapper
  is now a pure passthrough.
- handler/available_channel_handler.go: drop the middleware2 alias
  (no name collision in this file).

Frontend
- utils/pricing.ts: extract formatScaled, used by SupportedModelChip
  and PricingRow.
- api/admin/channels.ts: re-export BillingMode from constants/channel;
  tighten Channel.status / billing_model_source to ChannelStatus /
  BillingModelSource (and same for AvailableChannel).
- components/channels/AvailableChannelsTable.vue: drop dead
  withDefaults wrapper (loading is required, both call sites pass it).
- views/admin/AvailableChannelsView.vue: drop the redundant
  || BILLING_MODEL_SOURCE_CHANNEL_MAPPED fallback (now applied in
  service layer); remove unused import.
- i18n zh + en: delete unused tierLabel and tokenRange keys from
  both availableChannels.pricing and admin.availableChannels.pricing.

Tests
- New: SupportedModels_ExactKeyUsesPricedCaseWhenAvailable locks the
  pricing-case-wins rule.
- New: SupportedModels_AsteriskOnlyMappingExpandsAllPriced documents
  the "*" expansion rule.
- Admin handler: existing tests adjusted to pass an explicit
  BillingModelSource (default-fill is now exercised by service tests).

Add a read-only aggregate view per channel: its linked groups and a
deterministic wildcard-free supported-model list with pricing details.

Backend
- service.Channel.SupportedModels(): combine ModelMapping keys with
  same-platform ModelPricing.Models; trailing "*" keys expand via
  pricing prefix match; platforms without a mapping produce no
  entries (intentional "no mapping = not shown" rule).
- Extract splitWildcardSuffix() shared with toModelEntry.
- Build a per-call pricing lookup map (platform+lowerName -> *pricing)
  to avoid O(N*M) scans in SupportedModels.
- ChannelService.ListAvailable() aggregates channels + active groups;
  filters out group IDs no longer active.
- Admin route GET /api/v1/admin/channels/available returns the full
  DTO (id, status, billing_model_source, restrict_models, groups,
  supported_models).
- User route GET /api/v1/channels/available applies three filters:
  Status==active, visible-group intersection, and platform filter
  on supported_models (prevents cross-platform leak when a channel
  links to both a user-accessible group and an inaccessible one on
  another platform). Response is a plain array (matches the
  /groups/available sibling shape). Field whitelist omits
  billing_model_source, restrict_models, ids, status, sort_order.

Frontend
- New /admin/available-channels and /available-channels views backed
  by a shared AvailableChannelsTable component (admin adds status +
  billing-source columns via slots).
- PricingRow extracted to its own SFC; SupportedModelChip references
  shared billing-mode constants in constants/channel.ts.
- Sidebar: new entry above "渠道管理" for admin; matching entry in
  user nav.
- i18n: zh + en coverage for both namespaces.

Tests
- SupportedModels: wildcard-only pricing skipped, prefix-matches-
  nothing, cross-platform bleed, case-insensitive dedup, empty
  platform mapping.
- ListAvailable: nil groupRepo, inactive-group-ID dropped, stable
  case-insensitive name sort.
- User handler: 401 on unauthenticated, visible-group intersection,
  platform filter on supported_models, JSON whitelist.
- Admin handler: full DTO including default BillingModelSource
  fallback.

Refs: issue #1729

- AdvancedRequestConfig 把 headers textarea 换成行式：每行 name 输入 + value 输入
  + 删除按钮，底部「+ 添加 Header」。直观区分名/值，不用再一行 "Key: Value" 自己拆。
- 校验下放到行级：name 含空格或冒号才报错，未填仅占位不报错（避免输入时频繁红字）。
- 外部 props 同值不回写，避免 commit 后行被重排。
- chore: 移除 CLAUDE.md 里 silentflower remote 行（不再追踪）。

- History retention 1d → 30d（60s × 30d ≈ 43200 行/model，PG 无压力）；
  ComputeAvailability* 不再 UNION rollup 表，直接扫 histories 精度更高。
- Timeline bar 四级高度+颜色双重编码：operational 高+绿 / degraded 中+黄 /
  failed+error 短+红 / 未测试 很短+灰。
- migration 113 seed「Claude Code 伪装」模板（ON CONFLICT DO NOTHING）。
  user_id 用 legacy 格式（user_<64hex>_account_<uuid>_session_<uuid>），
  避免新版 JSON 字符串内嵌 JSON 在编辑器里一长串 \" 难读。
- MonitorAdvancedRequestConfig 加「格式化」按钮 + white-space:pre
  让 body textarea 对长字符串不压扁。

Apply flow:
- POST /admin/channel-monitor-templates/:id/apply now requires monitor_ids
  (non-empty array). Service applies the template only to the selected
  subset, gated by AND template_id = :id (so users can't sneak in
  unrelated monitor IDs).
- New GET /admin/channel-monitor-templates/:id/monitors returns the
  associated monitor briefs (id/name/provider/enabled) for the picker.
- ApplyToMonitors signature gains monitorIDs []int64; empty list returns
  ErrChannelMonitorTemplateApplyEmpty.

Frontend:
- New MonitorTemplateApplyPickerDialog.vue: list of associated monitors
  with checkboxes (default all checked), 全选 / 全不选 shortcuts, live
  selected/total count. Submit calls apply(id, ids).
- MonitorTemplateManagerDialog replaces the old ConfirmDialog flow with
  the picker; onApplied refetches the list to refresh associated counts.

i18n: applyPicker* + common.selectAll keys.

chore: bump version to 0.1.114.33

The CC 2.1.114 (sdk-cli) UA / APIKeyBetaHeader / JSON metadata.user_id
baseline (already verified working via the in-process apply on prod
template id=1) is documented in internal/pkg/claude/constants.go and
is what the seed template in the manager UI should follow.

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

The "CHANNEL · STATUS" breadcrumb and the zh/en subtitles above the
window-picker were redundant with the existing "渠道状态" page title
shown in the layout header. Remove the left column and right-align the
7d/15d/30d tabs + overall chip.

Also drop the now-unreferenced channelStatus.hero.* i18n keys from both
locales (grep confirms no remaining usage).

chore: bump version to 0.1.114.31

- AppSidebar 三处菜单项（管理端渠道监控、用户端/个人页渠道状态）按
  channel_monitor_enabled 条件展开，关闭时隐藏
- ChannelStatusView setInterval 随开关启停：关闭 clearInterval，
  开启/未知态自动启动，避免禁用功能后仍在轮询
- MonitorFormDialog provider Select 改为 3 色单选按钮
  （openai=emerald / anthropic=orange / gemini=sky），i18n 文案
  供应商 → 平台 / Provider → Platform
- MonitorKeyPickerDialog 按钮列表改为 name/key/group 三列表格 +
  搜索框，按 key.group.platform === provider 过滤，避免跨平台误选
- form.provider 变化时清空 api_key，修复切换平台仍保留旧 key 的
  错配 bug
- providerPickerClass 抽取到 useChannelMonitorFormat composable，
  统一 emerald/orange/sky 颜色语义，消除硬编码 Tailwind class 重复
- maskApiKey 工具函数统一（utils/maskApiKey.ts），KeysView 与
  MonitorKeyPickerDialog 共用 slice(0,6)...slice(-4) 策略
- bump version to 0.1.114.27

Subtitle + breadcrumb already convey context; the giant h1 was visual
noise. Drops orphan i18n key `channelStatus.hero.title` and shrinks
hero section vertical padding accordingly.

Bump VERSION to 0.1.114.26

Settings:
- New "功能开关" tab between 通用设置 and 安全与认证
- ChannelMonitorEnabled toggle: runner skips scheduling when false,
  user-facing list returns empty
- ChannelMonitorDefaultIntervalSeconds (15-3600): pre-fills interval
  when creating a new monitor; each monitor can still override

Bug fix:
- ModelTagInput now commits pending input on blur, not just Enter/Tab.
  Previously clicking "save" with an un-Enter'd extra model would drop
  the value (DB stored extra_models=[] even when user typed entries).

Backend:
- domain_constants: SettingKeyChannelMonitor{Enabled,DefaultIntervalSeconds}
- SettingService.GetChannelMonitorRuntime: lightweight getter used by
  runner tick + user handler per-request (fail-open on DB error)
- Runner tickDueChecks: bails early when feature disabled
- ChannelMonitorUserHandler: checks feature flag before serving
- Comment on runner doc: scheduler state is implicit (every tick re-reads
  ListEnabled from DB), so CRUD ops on monitors self-maintain the schedule

Bump VERSION to 0.1.114.25

Reference check-cx UI: INTELLIGENCE MONITOR hero + 3-column card grid
with 60-point timeline bars.

Backend:
- Add PrimaryPingLatencyMs + Timeline[60] to UserMonitorView
- ListRecentHistoryForMonitors: batch CTE + ROW_NUMBER() window query
- indexLatestByModel / indexAvailabilityByModel helpers

Frontend:
- 7 new components: ProviderIcon, MonitorMetricPair, MonitorAvailabilityRow,
  MonitorTimeline, MonitorHero, MonitorCard, MonitorCardGrid
- ChannelStatusView 381→~180 lines (delegated to subcomponents)
- AbortController reload concurrency protection
- HSL 0-120° availability color mapping
- Replace emoji with Icon component (bolt / globe)
- i18n: monitorCommon.* shared namespace, channelStatus.hero.*

Bump VERSION to 0.1.114.24

Pairs with the backend structured payment errors (reason + metadata). The
frontend now maps reason codes to localized messages with metadata as
interpolation variables, and automatically localizes raw config-field names
(e.g. "certSerial" → "证书序列号") using the existing UI-label i18n
namespace.

- frontend/src/utils/apiError.ts
  - extractApiErrorCode now prefers the string `reason` over the numeric HTTP
    `code`; reason is granular enough to drive i18n lookup, HTTP code is not.
  - New extractApiErrorMetadata to pull interpolation params off the error.
  - New extractI18nErrorMessage(err, t, namespace, fallback): looks up
    `<namespace>.<REASON>` in i18n and substitutes metadata. Before
    substitution, `metadata.key` and `metadata.keys` (slash-joined) are
    re-translated through `admin.settings.payment.field_<key>` so users see
    "缺少必填项：证书序列号" instead of "缺少必填项：certSerial".

- frontend/src/i18n/locales/{zh,en}.ts
  - Add payment.errors entries for every structured reason code returned by
    the backend (PAYMENT_DISABLED, INVALID_AMOUNT, TOO_MANY_PENDING,
    DAILY_LIMIT_EXCEEDED, NO_AVAILABLE_INSTANCE, PAYMENT_PROVIDER_MISCONFIGURED,
    WXPAY_CONFIG_MISSING_KEY / INVALID_KEY_LENGTH / INVALID_KEY, NOT_FOUND,
    FORBIDDEN, CONFLICT, INVALID_ORDER_TYPE, INVALID_STATUS,
    BALANCE_NOT_ENOUGH, REFUND_AMOUNT_EXCEEDED, REFUND_FAILED, and more),
    with placeholders for template variables.

- 13 payment-related Vue files
  - Migrate catch-block error reporting from extractApiErrorMessage to
    extractI18nErrorMessage(err, t, 'payment.errors', fallback).
  - Remove the ad-hoc paymentErrorMap computed in SettingsView.vue, which the
    new helper supersedes (it reads i18n directly via t).

- frontend/src/components/payment/providerConfig.ts
  - wxpay: publicKey and publicKeyId are now required (was optional), matching
    the pubkey-only verifier direction; certSerial is already required.

This PR is drop-in safe: reason-preferring extractApiErrorCode is backward
compatible with callers that pass their own i18nMap, and error codes missing
from i18n fall back to the existing message-based path.
