Dimujing (Earth Mother Classic) (黃帝地母經)

The sixty agricultural year-poems every 通書 prints beside the Spring Ox — one 詩曰 + 卜曰 pair per sexagenary year, forecasting rain, silkworms, mulberry and grain in Song-era geography (吳楚, 荊楚, 燕魏). THE SELF-GUARDING LAW asserted at load: every poem OPENS by naming its own year (太歲甲子年，水潦損田疇…), locking position, ganzhi and text together across all 60. Parsed from a full witness, cross-checked character-identical against an independent partial witness and the encyclopedia's 甲子 quotation; the one interleaved 卜曰 spliced from the second witness, noted. Query by civil year (lunar-new-year caveat stated), by ganzhi, or by date resolved through the real lunar year. Served as calendar culture — the modern habit of reading current events into its lines is a reader's practice this engine does not join.
