- Send Idempotency-Key on node create/patch/update writes (including bulk,
link, move, kanban and agent-node tools) and return the key used, so an
ambiguous failure can be retried without duplicating the write.
- Record a non-secret marker when login renewal is rejected; nap_whoami
reports auth_required ahead of gateway state, and local-index answers
carry stale warnings instead of silently serving old memory.
- Add nap_kanban_claim_next: pick and claim in one call, skipping cards
held by another operation, never replaying an ambiguous claim.
- Add nap_changes_since over /v1/projects/{id}/changes with a
per-worktree cursor that only advances after a successful read.
- Report real links_count/backlinks_count from indexed edges.
- Accept optional tool_profiles in .napseer/project.json when
NAPSEER_TOOL_PROFILES is unset.
