1. Durable Batch Aggregation

• 1.1 Add bounded same-stream entry aggregation to the Run log spool while preserving contiguous sequence and checksum validation.
• 1.2 Flush partial aggregation state at lifecycle/process completion and durable-uploader shutdown.

2. Backlog Delivery

• 2.1 Update the log uploader to keep draining pending batches within its bounded log-channel work budget.
• 2.2 Preserve retry, acknowledgement, and old one-entry spool segment compatibility.

3. Verification

• 3.1 Add unit coverage for aggregation boundaries, restart/retry behavior, and multi-entry acknowledgement cleanup.
• 3.2 Add runtime coverage proving a high-volume stream catches up through bounded aggregated uploads.
• 3.3 Run go test ./... in run/, scripts/check-structure.sh, and openspec validate batch-run-log-spool-upload --strict.
