+Log volume optimization verification
+
+Changed branch/fields:
+- access log level: successful GET/HEAD 2xx/3xx -> DEBUG; writes and 4xx/5xx -> INFO
+- logging.maxFileSizeMb / LOG_MAX_FILE_SIZE_MB: default 20
+- logging.maxFiles / LOG_MAX_FILES: default 5
+- rotated files use app-YYYY-MM-DD.N.log and participate in retention cleanup
+
+Source evidence:
+- Input log: /Users/yml/Downloads/logs/app-2026-08-29.log
+- Baseline: 2,080,480 lines, 767,799,564 bytes (732MB)
+- Access logs: 1,412,784 lines; successful access logs: 1,406,234 lines / 727,296,842 bytes
+- Largest paths: /api/v1/files/object 555,995; /api/v1/worker/hall/orders 446,763
+- Applying the new GET/HEAD success filter to this sample would skip 1,354,940 lines / 702,650,714 bytes, a simulated 91.51% reduction.
