derived/align_almagest.txt. A research program Kieran shapes and a model (the "seat") writes down. "I" in these files is the seat unless a line is quoted as his. The first write-up explained the misses instead of counting them; Kieran's objection ("this is cyclic") is in the file, and so is the retraction. Snapshot of 2026-10-15 from the private repo; local addresses and paths scrubbed, nothing else changed.

9 usable records (of 10); 9 with an hour relative to midnight
2305 computed lunar eclipses (umbral) in -1100..400
cells with day matches = max AND hour matches ≥ 7: 2
epochs tied at the maximum day score: 95 (lunar eclipses recur every saros, 6585 days; day-level matching cannot tell those apart, hours can)
