Composite public aliases (e.g. all/claude) reach the Anthropic/Gemini
billing core via OriginalModel/ChannelMappedModel source overrides.
Unknown aliases resolved to no pricing and silently recorded $0 cost,
while family-word aliases were mispriced by the fallback family match
(Opus traffic billed at the Sonnet fallback rate). The OpenAI path
already guards this via usageBillingModelCandidates; the shared
recordUsageCore had neither the guard nor a fallback.
- composite groups: unless the admin explicitly configured channel
pricing for the alias (OpenRouter-style custom pricing), bill by the
concrete forwarded model
- general safety net: when the selected billing model has no resolvable
pricing at all, fall back to the concrete forwarded model instead of
silently recording $0
- grok media usage records now attribute OriginalModel to the client
requested public alias, consistent with every other endpoint
(billing unaffected: empty BillingModelSource never triggers source
overrides)
Priced traffic and non-composite groups are unaffected.
The composite-groups PR (#3581) replaced the raw ent SubscriptionPlan
response of GET /admin/payment/plans with a projection struct but
dropped the currency field added by #4323. PlanEditDialog then read an
undefined currency, sent an empty string on save, and silently wiped
the stored plan currency. Restore currency plus created_at/updated_at
so the projection preserves the full original response shape.
formatMultiplier rounded any value >= 0.01 with toFixed(2), so a
configured multiplier like 0.035 displayed as 0.04x in the /usage and
/admin/usage cost tooltips. Format with up to 4 decimals and trim
trailing zeros while keeping at least 2 decimals; display-only fix,
billing amounts were already computed from the true multiplier.
govulncheck newly flags GO-2026-5970 (infinite loop on invalid input in
golang.org/x/text < v0.39.0), causing every fresh backend-security CI run
to fail. Upgrading x/text pulls sibling golang.org/x/* modules
(crypto/mod/net/sync/sys/term/tools) to their matching minor versions.
Remove unsupported none handling, align the auth cache version with the current baseline, consolidate the unshipped migrations, and update the public API contract.
Persist reasoning ceilings and exact mappings for OpenAI groups, enforce them across HTTP and WebSocket forwarding, and invalidate cached auth snapshots.
