tegwick 08a2148079 spec(SHARD-WP-0006 T2): event-sourced coordination + per-space append authority 
Resolves B-1+B-3. Coordination-canonical state = an append-only decision log
in the git journal (events: overlay/binding/alias/merge); queryable current
state = a derived fold (tier-3, indexed). Concurrency: one append authority
per space (lease/leader) → totally-ordered per-space log, read-your-writes
across instances, HA via re-grantable lease, partition yields to log integrity.
Updates §1, §4, §8.1, §8.6, §11. I-6 strengthened (coordination state is now
git-addressable history/patch/review), not bypassed.
