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filters out group IDs no longer active.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.
