Drift report, 2026-10-16 (tenth) | Development analyses

Owner words. None new in the records since the fifth report.
Mix. Recent merges: venture depth (league-schedule-generator pool play, shift-roster-builder pins), pages categories, process. No new single-page calculators.
Instruction lines. No file grew; nothing cut.
Audit. league-schedule-generator (#7513) re-run: 69 pass, 0 fail.
Fix. Friction from prompts/routing.json and review/prompt-2.md repeats ("fifth review of the day... little new to measure"): ten reviews today at review_every 20. Raised to 40.
Open. derive.py fetch got 16 of 18 PRs. ventures/2, research/1 and review/2 still overlap or have too few runs.
Proposals: none.
