Qingnang Aoyu 青囊奧語 doubtful — surfaces in the Song (per Siku)
Esoteric Sayings of the Green Satchel: genuinely catalogued in the Imperial Library's own bibliography — and, by that same catalogue's dating, a text that "only surfaces in the Song" 「至宋始出」.

What it contains
Per the collation register:
- Distinguishing the nobility and fortune of mountains and waters through yin-yang forward/reverse sequences and the nine stars' transformations 陰陽順逆、九星化曜.
- The 24 mountains divided into forward and reverse 二十四山分順逆; wood, fire, metal and water assigned across 甲丙庚壬 and 乙丁辛癸, mutually raising the growth cycle 互起長生, yielding 48 configurations 四十八局; yang turning left, yin turning right 陽用左旋，陰從右轉.
What the Siku cataloguers concluded
The notice states the work 「至宋始出」 ("only came to light in the Song"), and credits it as 「為地學理氣家之權輿」 ("the fountainhead of the liqi school of earth-lore") — Siku Quanshu Zongmu, vol. 109.
Both halves matter and must travel together: the catalogue is the source both of the text's canonical standing and of the dating that undercuts its Tang attribution. Our register accordingly records authorship as doubtful 作者存疑 — not as spurious, a verdict the catalogue does not issue here.
Where it sits in the tradition
Matrix row: Three-Cycle 三元 main body ◎, Form 形巒 partial ○. It stands in the 地理辨正 canon alongside the 青囊經 and 天玉經. Its 24-mountain sequences are among the classical anchors our engine's compass module must interpret; the replacement-star reading dispute is logged in the School Dispute Register.
