水洊至，习坎。君子以常德行，习教事。

Rehearse the Recovery Before the Risk Returns
Read Hexagram 29 Kan as repeated danger answered by repeated practice, then prove one recovery path on a safe offline copy.

Hexagram 29 · Kan · The Abysmal Water
This page studies a supplied Xiang image. It does not claim this hexagram was cast for the modern scene.
Textual correction
The bundled Yang Tiancai and Zhang Shanwen OCR reads 水存至; Yarrow normalizes the character to 水洊至 using the Zhouyi Shangshi Xue witness and the Yang/Zhang annotation that explicitly identifies 洊.
Primary OCR witness. 水存至，习坎。君子以常德行，习教事。
Corrected public reading. 水洊至，习坎。君子以常德行，习教事。
Source image
Water reaches one hollow after another and continues through repeated danger without skipping the next passage.
Concrete tension
The same operational risk has appeared more than once, but its recovery procedure exists only as an unread document.
Visible modern action
On an offline copy, run one backup-restore drill from start to verified readback. Record the duration, the first failed step, and one correction; do not touch production.
Why this action comes from this source
The repeated arrival of water and the instruction to rehearse make recurrence the reason for practice. A real offline restore, verified readback, and recorded correction demonstrate repetition safely instead of substituting another written plan.
Reflection question
Which repeated risk has a written plan but no completed rehearsal?
Audience value
Informative: it turns repeated danger into a safe restore drill with observable evidence and an explicit production boundary.
Source boundary
The Chinese quotation is checked against Yarrow's bundled Yang Tiancai and Zhang Shanwen source text. Where that OCR witness substitutes a character, the page discloses the raw reading and checks the correction against a second classical witness. The English translation, objects, tension, and action are modern Yarrow editorial work. This is not a fresh cast, prediction, or promised outcome.
