feat: add batch accounting engine and sweeper

[SahilChoudhary22]

Summary

Introduces a new batchaccounting package that handles delayed cost settlement for provider batch jobs. When a batch job completes asynchronously, this package prices the results, writes an aggregate cost log entry, reports governance usage, and advances the job's coordination state through a well-defined state machine.

Changes

• accounting.go: Core settlement logic via AccountBatchResults. Handles ownership fencing via a runner ID claim, idempotent aggregate log writes (CreateIfNotExists), governance usage reporting, and graceful handling of unpriced batches (missing model, missing batch pricing rates, parse errors). Unpriced batches with real token usage are still logged with a nil cost so the missing-cost backfill can recover them once rates are available. Provider-specific usage extraction is implemented for OpenAI, Anthropic, Bedrock, and Gemini, including both cache-token wire conventions (inclusive vs. exclusive of base prompt tokens).

• sweeper.go: A Sweeper that polls ListDueBatchJobs, retrieves provider status, fetches results for completed batches, and calls AccountBatchResults. Includes capped exponential backoff with deterministic jitter, a KV-store-backed poll lease to prevent concurrent provider calls for the same job across nodes, per-instance random runner IDs to keep ownership fences meaningful, and bounded per-provider-call timeouts to prevent a hung call from stalling the entire sweep.

• doc.go: Package-level documentation covering the two-store design rationale, at-least-once settlement semantics, the known double-count window for governance reporting, and ownership fencing behavior.

• accounting_test.go: Unit tests covering multi-model aggregation, idempotent retry behavior, partial pricing metadata, governance deduplication across retries, cache token convention normalization, mixed unpriced attribution safety, and fail-closed behavior on persisted job read failure.

• batchpricing_test.go: Integration-style tests using a real pricing datasheet fixture to validate end-to-end cost calculation for Anthropic, Gemini, and Bedrock models, including multi-model batches and the unpriceable-but-logged path for models with no batch rates.

• testdata/pricing.json: Minimal pricing fixture for the integration tests.

Notable design decisions:

• The aggregate log write and governance marker are not transactional; idempotency relies on CreateIfNotExists and the AggregateLogWrittenAt/GovernanceReportedAt markers, so retries resume rather than redo work.
• A failed read of the persisted job fails closed and releases the claim, preventing settlement on top of unknown markers that could cause double-reporting.
• Parse errors in batch results short-circuit to unpriceable without writing any log row, since the result set is not trustworthy.

Type of change

• Bug fix
• Feature
• Refactor
• Documentation
• Chore/CI

Affected areas

• Core (Go)
• Transports (HTTP)
• Providers/Integrations
• Plugins
• UI (React)
• Docs

How to test

go test ./framework/batchaccounting/...

The batchpricing_test.go tests load testdata/pricing.json via the file:// scheme and exercise the full sweep-to-settlement path against a real ModelCatalog.

Breaking changes

• Yes
• No

Security considerations

Runner IDs used for ownership fencing are generated with crypto/rand to prevent collisions across nodes sharing a database. No PII or secrets are introduced; batch IDs and provider names are the only identifiers stored in KV lease keys.

Checklist

• I read docs/contributing/README.md and followed the guidelines
• I added/updated tests where appropriate
• I updated documentation where needed
• I verified builds succeed (Go and UI)
• I verified the CI pipeline passes locally if applicable

Walkthrough

Adds the batchaccounting package for provider usage extraction, pricing, deterministic aggregate logs, governance reporting, attribution, and batch finalization. Adds a sweeper for polling, leases, retries, backoff, and terminal accounting.

Changes

Batch accounting lifecycle

Layer / File(s)	Summary
Accounting contracts and settlement framework/batchaccounting/accounting.go, framework/batchaccounting/doc.go, core/schemas/batch.go	Defines settlement contracts, claim fencing, aggregate-log creation, attribution, incomplete totals, governance reporting, and batch finalization.
Provider usage extraction and pricing coverage framework/batchaccounting/accounting.go, core/providers/vertex/vertex.go, framework/batchaccounting/batchpricing_test.go, framework/batchaccounting/testdata/pricing.json, framework/batchaccounting/accounting_test.go	Normalizes usage for OpenAI, Bedrock, Gemini, Vertex, and Anthropic. Covers cache tokens, fallback pricing, unknown models, parse errors, and multi-model batches.
Polling and settlement orchestration framework/batchaccounting/sweeper.go	Polls due jobs, retrieves provider state and results, applies leases and timeouts, schedules retries, and accounts terminal jobs.
Accounting behavior validation framework/batchaccounting/accounting_test.go	Tests aggregation, pricing, attribution, idempotency, reporting, leases, runner IDs, persistence failures, parse errors, and sweeper transitions.

Estimated code review effort: 5 (Critical) | ~90 minutes

Merge Risk: 🟠 High · up to 68ec8

Batch settlement can undercount Gemini usage and lose valid cost attribution when one usage payload is malformed, while retry and claim handling can delay recovery or create repeated provider polling. These correctness and availability risks should be fixed or explicitly accepted before merging.

- Around line 102-104: Update the job-processing loop around sweepJob to check
ctx.Err() before sweeping each job and stop processing immediately when the

remaining jobs. Apply the same cancellation guard to the additional sweep loops
identified in the diff.
- Around line 232-250: The poll lease cleanup currently deletes the key
unconditionally, allowing an expired lease to remove a newer worker’s lease.
Update acquireProviderPollLease and deletePollLease to store and retain a unique
per-attempt lease token, then add and use a KVStore conditional-delete operation
that removes the key only when its token matches; preserve the existing
no-KVStore behavior and warning handling.

In `@framework/batchaccounting/testdata/pricing.json`:
- Around line 2-9: Update the pricing fixture entries for claude-sonnet-5,
anthropic.claude-sonnet-4-6, and global.anthropic.claude-sonnet-4-6 to use the
actual batch rates, then adjust the expected totals in the batchpricing tests to
match; use synthetic model names instead only if retaining the current values is
intentional.

derived context to both calls and release each timeout context after its
corresponding call.
- Around line 59-61: Update the sweeper initialization around config.ClaimedBy
so each sweeper instance has a unique runner ID: require a caller-provided
non-empty value or generate a unique ID once at startup, rather than defaulting
to the shared "batch-sweeper" string. Ensure the resulting ID is consistently
used by ClaimBatchJob and terminal-state fences.

Release the claim when MarkBatchJobUnpriceable fails.

Every other failure path in this function calls FailBatchJob before returning. This path does not. The job stays fenced on this runner until defaultClaimTTL expires, so a retry waits five minutes for no benefit. The same gap exists at Line 362.

Release the claim when the unpriceable transition fails.

Every other failure path in AccountBatchResults calls FailBatchJob before returning. These two paths return the error while the job stays in the claimed state. The job then blocks any retry until defaultClaimTTL expires.

entry.Cost aliases summary.Cost.

Cost: &summary.Cost shares one float64 between the persisted log entry and the summary returned to the caller. Today no code mutates summary.Cost after this point, so behavior is correct. A later change to either value would silently change the other. Copy the value instead.

174-179: 🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Compute the reschedule timestamp after the provider calls return.

now is captured in SweepOnce at Line 138, before the serial per-job work begins. Every reschedule call site passes that value: Lines 174, 179, 203, 209, and 275.

Two effects compound:

• A single provider call can run up to defaultProviderPollTimeout (5 minutes). With the default Interval of 1 minute, nextCheckAt returns now + 1m + jitter, which is already in the past when UpsertBatchJob persists it.
• The sweep is serial over up to Limit (50) jobs, so later jobs in the list receive an even older base timestamp.

ListDueBatchJobs then selects the job again on the next sweep. Backoff and jitter are skipped for the slowest jobs. PollAttempts still increments, so the job is not stuck forever, but it consumes the 120-attempt budget at the sweep interval instead of at the intended backoff interval.

Pass a fresh timestamp to reschedule.

🐛 Proposed fix

-		s.reschedule(ctx, job, now)
+		s.reschedule(ctx, job, time.Now().UTC())
 		return
 	}
 	if retrieved.ID != "" && retrieved.ID != job.BatchID {
 		s.warn("batch accounting sweeper retrieve returned mismatched batch id job_id=%s", job.ID)
-		s.reschedule(ctx, job, now)
+		s.reschedule(ctx, job, time.Now().UTC())
 		return
 	}

Apply the same change at Lines 203, 209, and 275. Alternatively, drop the now parameter from reschedule and read the clock inside it, so no call site can pass a stale value.

984-989: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Treat an empty JSON array as no attribution.

hasBatchJobAttribution returns true when job.BudgetIDs holds the literal "[]". In that case buildAggregateLog takes the batch-job attribution branch and skips applyLogAttribution entirely, so the row gets no selected key, no virtual key, and no budget or rate-limit ids. The BaseLog identity is discarded.

The writer stores nil for empty lists, so this state should not occur today. A cheap guard keeps the reader safe if any other writer persists "[]".

♻️ Proposed guard

+// emptyJSONList reports whether a persisted JSON list column holds no entries.
+func emptyJSONList(raw *string) bool {
+	if raw == nil {
+		return true
+	}
+	trimmed := strings.TrimSpace(*raw)
+	return trimmed == "" || trimmed == "[]" || trimmed == "null"
+}
+
 func hasBatchJobAttribution(job *cstables.TableBatchJob) bool {
 	if job.SelectedKeyID != "" || (job.VirtualKeyID != nil && *job.VirtualKeyID != "") {
 		return true
 	}
-	return (job.BudgetIDs != nil && *job.BudgetIDs != "") || (job.RateLimitIDs != nil && *job.RateLimitIDs != "")
+	return !emptyJSONList(job.BudgetIDs) || !emptyJSONList(job.RateLimitIDs)
 }

This requires adding "strings" to the import block.
