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).
