The announce intent says a reservation records who owns an item, but universal patterns puts multi-agent claims in `.abcd/coordination/`

The announce intent says a reservation records who owns an item, but universal patterns puts multi-agent claims in .abcd/coordination/

A scope leakage (severity minor) found by the cross-document consistency pass.

• End A: .abcd/development/intents/planned/itd-2609151838312703-sessions-announce-what-they-are-doing.md:91 — "who owns an item is its reservation"
• End B: .abcd/development/brief/05-internals/04-universal-patterns.md:139 — "multi-agent claims per itd-33) lives at .abcd/coordination/"

itd-2609151838312703 rules that who owns an item is its reservation on the shared remote, and that a release hold is a reservation too. 04-universal-patterns says coordination state, including multi-agent claims per itd-33, lives at .abcd/coordination/ inside the repository. Ownership of an item is placed in two stores with different reach, and neither document says which one a session reads.
