Exit code 3 means an absent corpus in the library chapter and contention in the land chapter.

Exit code 3 means an absent corpus in the library chapter and contention in the land chapter.

A naming conflict (severity minor) found by the cross-document consistency pass.

• End A: .abcd/development/brief/04-surfaces/07-library.md:210 — "exits 3, a code distinct from a refusal, so a script can tell"
• End B: .abcd/development/brief/04-surfaces/38-land.md:201 — "A landing a release cut holds exits 3, contention, as every verb that backs off does"

07-library has every corpus verb exit 3 when no corpus exists, as a code distinct from a refusal. 38-land says exit 3 is contention, used by every verb that backs off, and keeps a failed fetch off 3 because an automation backing off on 3 would wait on no one. An automation that follows the land chapter would wait indefinitely on a library verb whose corpus is simply missing.
