+**P2 live on the first company's books, 2026-10-20 (slice 9).** Asked one
+at a time: the old copies move aside (Q-3), backups go to a new private
+repository on the owner's git server and to his Syncthing folder (Q-1,
+D-30). Adopted as "fernhill" at event 466, 66 stored files and the TIN
+vault checked; `books.verify` ok on the new server with the same head; the
+CPA package as of 2026-10-11, 2026-10-17 and 2026-10-20 canonically
+byte-identical before and after (record in that books dir,
+`goldens/p2-cutover-2026-10-20/`); both backups whole by a restore
+preview. The cutover added `wanderbooks books put-aside` (three review
+rounds of data safety), which moved the old copies whole into the private
+folder's `legacy/`. Agents connect with `wanderbooks connect`, the viewer is
+`wanderbooks gui fernhill`, and the books dir is a books home holding no
+books data. The before-check found defect 21 again (the IIF ignores
+`as_of`).
+
+**Next:** P3 (engine correctness; designed: one brief per defect group,
+each attacked by a reviewer, kept outside this public repo since they cite
+the first company's figures; the owner's questions come one at a time as
+each is built), then P4-P13 as planned. P11: one app for Windows, Mac and
+Linux (D-24). P12: max testing again (D-33). P13: bookspec (D-34), a
+formal, sourced accounting specification first, then its own formal
+validation and a conformance harness for any engine; P3's regression
+tests are its first examples.
