- quota.go: add missing SettleBilling call in PostWssConsumeQuota
- text_quota.go: gate InjectTieredBillingInfo on tieredBillingApplied bool
instead of tieredResult != nil, so fallback billing still logs metadata
- price.go: remove quotaBeforeGroup == 0 from freeModel condition to avoid
bypassing settlement for output-only expressions
- tiered_settle.go: split cc/cc1h subtraction using UsageSemantic to
distinguish OpenAI vs Claude cache creation token formats
- pricing.go: only set BillingMode when a non-empty expression exists
- useModelPricingEditorState.js: only write billing_mode when
finalBillingExpr is non-empty
Remove the intermediate branch that recomputed quota from
EstimatedQuotaBeforeGroup when tieredResult is nil. This discarded the
FinalPreConsumedQuota fallback that TryTieredSettle already selected.
Now the error path simply adds tool surcharges to the passed-in
tieredQuota, preserving the existing fallback semantics.
Also removes unrelated mise.toml and adds a test covering the error
fallback with a pre-consumed quota that differs from the estimate.
