WalkthroughThe change adds optional cost breakdowns to OCR, speech, and transcription usage. Logging now attaches and denormalizes costs, records batch lifecycle data, settles batch results, and manages an accounting sweeper. ChangesCost propagation and batch accounting
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The current head may not compile because the logging changes reference cost fields that are not present on the log type, so it is not merge-ready until that issue is fixed. Separate open concerns could also block responses, omit batch request counts after errors, or produce inconsistent billing columns. Sequence Diagram(s)sequenceDiagram

UpsertBatchJobcall with a timeout.
recordBatchJobLifecycleruns inline on thebatch_createandbatch_retrieveresponse path (Line 1809). It passesp.ctx, which is the plugin lifetime context and carries no deadline. A stalled batch store therefore blocks the caller's HTTP response indefinitely.accountBatchResultsalready bounds the same class of inline store work withbatchAccountingTimeoutfor this exact reason. Apply the same bound here.🛡️ Proposed fix

1821-1841: 📐 Maintainability & Code Quality | 🟠 Major | ⚡ Quick winExtract the shared breakdown-attachment logic.
This block duplicates the body of
attachCostBreakdowninplugins/logging/operations.go(Lines 1877-1888), including the comment text. The two copies already differ: this one runs only whenbreakdown.TotalCost > 0, andattachCostBreakdownruns for any non-nil breakdown. Billing denormalization logic that lives in two places will drift further. Extract a helper that applies an already-computed breakdown to an entry, and call it from both sites.♻️ Proposed refactor
Add the helper in
plugins/logging/operations.go:// applyBreakdownToEntry writes an already-computed breakdown onto the entry's // usage carrier, or denormalizes it into the cost columns when there is none. // A provider-supplied breakdown is preserved. func applyBreakdownToEntry(entry *logstore.Log, breakdown *schemas.BifrostCost) { if entry == nil || breakdown == nil { return } if entry.TokenUsageParsed != nil { if entry.TokenUsageParsed.Cost == nil { entry.TokenUsageParsed.Cost = breakdown } return } // No usage carrier (e.g. OCR: OCRUsageInfo has no tokens, so it is never // aliased into TokenUsageParsed). SerializeFields skips its cost block when // TokenUsageParsed is nil, so denormalize the split directly here. entry.InputCost = breakdown.InputCost entry.OutputCost = breakdown.OutputCost entry.AdditionalCost = breakdown.AdditionalCost }Then reduce both call sites:
if breakdown := p.pricingManager.CalculateCostBreakdown(result, pricingScopes); breakdown != nil && breakdown.TotalCost > 0 { cost := breakdown.TotalCost entry.Cost = &cost - // Attach the per-category split (input / output / cache) to the - // stored usage so log detail views can surface it. Preserve any - // provider-supplied breakdown. - if entry.TokenUsageParsed != nil && entry.TokenUsageParsed.Cost == nil { - entry.TokenUsageParsed.Cost = breakdown - } else if entry.TokenUsageParsed == nil { - // No usage carrier: OCRUsageInfo has no tokens, so OCR is never - // aliased into TokenUsageParsed. SerializeFields skips its cost - // block when TokenUsageParsed is nil, so denormalize the split - // directly here for the columns to reconcile to the cost column. - entry.InputCost = breakdown.InputCost - entry.OutputCost = breakdown.OutputCost - entry.AdditionalCost = breakdown.AdditionalCost - } - // Speech / transcription / OCR usage is not aliased into - // TokenUsageParsed, so write the split onto the native response too. + applyBreakdownToEntry(entry, breakdown) + // Speech / transcription / OCR usage is not aliased into + // TokenUsageParsed, so write the split onto the native response too. attachCostToNativeUsage(result, breakdown) }🤖 Prompt for AI Agents

Summary
Cost breakdowns were not being propagated to the native usage objects for speech, transcription, and OCR responses. Because these modalities do not alias their usage into
TokenUsageParsed, the computed cost split was silently dropped — leaving client-facing responses without cost data and log entry columns unreconciled when no usage carrier was present.Changes
Cost *BifrostCostfield toSpeechUsage,TranscriptionUsage, andOCRUsageInfoso these modalities can carry a per-category cost breakdown in their responses.attachCostToNativeUsageto write the computed breakdown onto speech, transcription, and OCR usage objects (both streaming and non-streaming), preserving any provider-supplied cost already present.attachCostBreakdownso it no longer bails out whenTokenUsageParsedis nil; instead, when there is no usage carrier (e.g. OCR), it denormalizes the split directly onto the log entry'sInputCost,OutputCost, andAdditionalCostcolumns so they reconcile to the cost column.applyNonStreamingOutputToEntryto aliasSpeechResponse.Usagetoken counts into aBifrostLLMUsagestruct, consistent with how other modalities are handled.nativecost_test.gocoveringattachCostToNativeUsageacross all three modalities, the provider-supplied cost preservation case, the no-usage-slot no-op case, and the denormalization path for entries without a usage carrier.Type of change

costfield in their usage objects when pricing data is available, and that log entries for OCR requests have non-zeroinput_cost/output_costcolumns.Breaking changes
