Effective immediately as the operational worker-count configuration of the steady-state ingestion runner. Scope : CONFIGURATION PROMOTION ONLY. No real Tickstory data is processed by this phase. No workload is run. No checkpoint is advanced. ``` ## 4. Effective operational configuration (after promotion) ```text operational workers = 24 SAFE_MAX_CHUNK_SIZE = 24 MiB (UNCHANGED) = 25,165,824 bytes nominal workload = 512 MiB (UNCHANGED) = 536,870,912 bytes parser = UNCHANGED (s251_parse, parser_version p3_s251_parser_v1) aggregator = UNCHANGED (s251_aggregate incl.

Unchanged controls / state ```text atomic chunk size = UNCHANGED (24 MiB; SAFE_MAX_CHUNK_SIZE 25,165,824) workload size = UNCHANGED (512 MiB; 536,870,912) real checkpoint = UNCHANGED (byte-identical; SHA before == after) checkpoint cursor = last_completed_chunk 209 | next_chunk 210 | next_byte_start 5,020,582,350 (5020582350) CHUNK 210 = NOT AUTHORIZED (factual state ONLY; this promotion grants no execution authorization) production MQL5/MQH = UNCHANGED frozen contracts = UNCHANGED historical evidence = UNCHANGED (runs, manifests, evidence, reports) P3-S25.1Q benchmark harness = UNCHANGED (disposable benchmark only) ``` ## 6. Implementation ```text CURRENT_PROJECT_STATE.md : v11 - OPERATIONAL EXECUTION CONFIGURATION (operational workers = 24) recorded; factual cursor unchanged. CURRENT_DECISION_GATE.md : v13 - promotion recorded (OPERATIONAL WORKER CONFIGURATION = 24, PROMOTED); CHUNK 210 remains NOT AUTHORIZED; next_chunk 210 factual. Operational runner source : verified - the current steady-state ingestion runner (s251_stageb_workload20.py) already embeds WORKERS = 24, ATOMIC_24 = 25,165,824 and MAX_WORKLOAD_BYTES = 536,870,912, and references the unchanged parser/aggregator. Historical 8-worker runners: NOT modified (s251_stageb_workload12..19.py stay byte-identical run records of the 8-worker operational series; their evidence is immutable). ``` ## 7. Evidence paths (reference; no datasets reproduced here) ```text Q decision : ml/p3/p3_s251_external_ingest/workload_benchmark/worker_scaling_q/output/p3_s251q_decision.json Q worker 24 : ml/p3/p3_s251_external_ingest/workload_benchmark/worker_scaling_q/output/p3_s251q_worker_24.json Q report : docs/P3_S25_1Q_WORKER_SCALING_OPTIMIZATION_REPORT.md R manifest : ml/p3/p3_s251_external_ingest/output/s251_real_workload20_manifest.json R evidence : ml/p3/p3_s251_external_ingest/output/s251_real_workload20_evidence.json R interruption : ml/p3/p3_s251_external_ingest/output/s251_real_workload20_interruption.json R mutations : ml/p3/p3_s251_external_ingest/output/s251_real_workload20_mutations.json R controls : ml/p3/p3_s251_external_ingest/output/s251_real_workload20_controls_before.json ml/p3/p3_s251_external_ingest/output/s251_real_workload20_controls_after.json R checkpoint SHA : ml/p3/p3_s251_external_ingest/output/s251_real_workload20_checkpoint_sha_before.json ml/p3/p3_s251_external_ingest/output/s251_real_workload20_checkpoint_sha_after.json R report : docs/P3_S25_1R_REAL_512MIB_24WORKER_VALIDATION_REPORT.md checkpoint : ml/p3/p3_s251_external_ingest/output/s251_real_checkpoint.json (READ-ONLY) ``` ## 8. Limitations ```text 1. Requested 24 worker processes; 22 atomic chunks -> 22 executor processes, [22,23] empty partitions. Recorded; gates exact; machine-derived. 2. 24 workers near-saturate the 24 logical CPUs (Q: avg 0.961/peak 1.000; R: avg 0.9169/peak 0.9796). Scaling above 24 was NOT tested (not in scope). 3. The promotion changes ONLY the operational worker-count setting; the historical 8-worker runner snapshots are intentionally NOT rewritten, so the pre-promotion operational value 8 remains visible only in those historical run records and their evidence. 4. The full 34.5 GB ingestion remains NOT COMPLETE; CHUNK 210 at byte offset 5,020,582,350 awaits a NEW explicit owner execution authorization. ``` ## 9. Classification ```text CLASSIFICATION : A - 24-WORKER CONFIGURATION PROMOTED Wording note : "A" is not forced. The promotion is based on existing machine evidence only (P3-S25.1Q + P3-S25.1R); no benchmark was re-run, no real Tickstory byte was read, no checkpoint was advanced, and all exact values above are machine-derived. ``` *End of P3-GOV-7 promotion record.*
