✅ Toolbar bundle — eager 2.37 MiB within budget
What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.

An internal callback validates and records generation requests, then schedules Temporal reconciliation. Task-run state exposes spend and request-tracking fields while protecting them from ordinary patches. Terminal updates and sandbox cleanup refresh spend for cloud runs.

In `@products/tasks/backend/temporal/process_task/activities/cleanup_sandbox.py`:
- Around line 98-102: The cleanup flow around process_pending_gateway_usage must
not finalize after a single bounded attempt or suppressed failure. Ensure
pending gateway usage is fully drained or a durable retry is scheduled before
sandbox destruction, session closure, and stream completion, applying the same
behavior to both affected handlers.
- Around line 65-68: Update the exception handling in the cleanup_sandbox
accounting lookup to catch ValueError only around UUID parsing, while allowing
ORM and service failures to propagate so the activity retries. Preserve the
existing warning log for invalid UUIDs and the cleanup flow for successfully
parsed identifiers.
In
`@products/tasks/backend/temporal/process_task/activities/update_task_run_status.py`:
- Around line 123-124: Update terminal status handling around
gateway_usage_enabled, refresh_task_run_spend, and resume_workflow_step_for_run
so workflow resume occurs only after all pending gateway usage has been durably
processed. If gateway results are unavailable, persist a retry and defer the
wake event until accounting completes; do not rely on a single bounded
process_pending_gateway_usage call.

26-32: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick winBound the activity below its Temporal timeout.
requests.get(..., timeout=(2, 3))does not impose a 5-second wall-clock limit. A gateway response that sends bytes within each 3-second read interval can keep_fetch_gateway_spendrunning past the 30-secondstart_to_close_timeout. The activity can then time out after earlier per-request writes committed, and the retry policy can retry the attempt.Enforce a hard wall-clock deadline for the HTTP call, or set the Temporal timeout from an established worst-case activity bound.

from an established worst-case activity bound, ensuring the activity cannot time

The reconciliation workflow waited with a growing backoff after every batch, even when the batch settled usage and more IDs remained. A backlog drain after a gateway outage took many minutes. A pass that reduces the pending count now runs the next batch at once. Passes that settle nothing keep the backoff.

Problem
We need to know what it costs to run a cloud task, with LLM and compute costs tracked separately. Tasks doesn't currently keep that breakdown in a form other products can use.
Changes
This records those costs against each run and gives backend callers totals for individual runs and the whole task. The gateway sends us generation IDs, which we use to look up settled LLM costs. Compute costs come from the sandbox sessions and rate cards we already have.
Reconciliation uses a separate workflow because gateway costs can settle after the task finishes, and accounting retries shouldn't hold up completion or cleanup.
The new accounting fields stay internal and are excluded from public API responses. Products will calculate customer spend separately using their own pricing. There's no UI change.

The callback checks the authenticated funding wallet separately from the Tasks tenant and acknowledges only after persistence and workflow scheduling.
Existing customer billing stays unchanged.
Note
The desktop and backend changes can deploy independently: older harnesses send no header, and older Django returns 404 without interrupting generation.
Deploy the registered Temporal workflow before enabling gateway callbacks.
Gateway callback delivery remains best effort; this PR does not add a gateway outbox.
Token totals remain unknown while generation IDs are pending; settled costs stay stored for reconciliation.
Cleanup persists compute without waiting for token settlement; the reconciliation workflow owns token retries.
How did you test this code?
PR checks report validation for the pushed commit.
Full Modal provisioning and the deployed gateway path remain unverified.
No event-table changes require native-JSON test coverage.
Release status
Gateway routing still requires the existing URL, product allowlist, and scoped-token configuration.
Automatic notifications
Docs update
The existing task-run API guide states that responses omit internal cost accounting. Callback deployment order and accounting limits are documented above.
🤖 Agent context
Autonomy: Human-driven (agent-assisted)
Agent: Codex, GPT-6 Astra (review fixes); PostHog Desktop, Claude Opus 5.5 (timestamp fix). The earlier implementation model was not recorded.
Merged master and addressed reconciliation, completion analytics, stale responses, and facade boundary findings.
The simplification pass removed unused adapters, repeated compute calculation, and cleanup-owned token retries.
