itd-10's destroy deletes a lifeboat and a logbook inside .abcd/; 03-configuration says neither namespace exists in any tree

A premise contradiction (severity minor) found by the cross-document consistency pass.

• End A: .abcd/development/intents/drafts/itd-10-purge-uninstall.md:16 — "AND the entire .abcd/ namespace (including lifeboat, dev artefacts, logbook, and config)"
• End B: .abcd/development/brief/05-internals/03-configuration.md:1367 — "Three namespaces are deliberately absent from every tree: voyage/, which is user-scope and never committed; logbook/, retired in favour of the local tier's logs; and lifeboat/, because the lifeboat is out-of-tree output at an operator-chosen destination."

itd-10's destroy removes the whole .abcd/ namespace, which it says includes a lifeboat and a logbook. 03-configuration says logbook/ is retired and lifeboat/ is absent from every tree, because the lifeboat is out-of-tree output. The deletion list names directories the configuration model says are never there.

• declined: Closed in the 2026-10-27 triage (dcn-2610271112330536) as a duplicate of iss-2610262031329436. Same itd-10 line and the same fix; this record adds that logbook was retired, which the primary's remedy already names.
