Total wall time:         9886.65 s

PBP rows (written):   4,198,546,157

Notes:
- FIRST SUCCESSFUL 100K full-pipeline run against ClickHouse Cloud.
  Previous attempt on Production Scale (2×4) tier hit the 4h replica
  deadline mid-PBP-write (super-linear scaling past 10K).
- 3×16 tier resolves the PBP scaling problem: throughput of 528K rows/sec
  at 100K vs 513K rows/sec at 10K — essentially flat.
- PBP write is now the dominant phase at 80% of wall time (2h 13m of the
  2h 44m total). Sim + merge + OC write combined are only 32 min.
- Peak client RAM 46.8 GB / 64 GiB — comfortable margin.
- PBP row count 4,198,546,157 matches the 10K×10 expected value.
- Cost estimate: ACI 2h 45m × ~$1/hr = $2.75; CH Cloud 3×16 × ~$8/hr =
  $22; total ~$25 per 100K full-pipeline run.
- DOES NOT INCLUDE SEASON CONTEXT — wiring for that landed in commit
  363a7726 after this run started. Next validation: 10K full-pipeline
  including season context, then 100K.
