The relay-owner key is intended to double as the service identity used by ngit-ci, but clients could only discover it through HTTP and owner-authored coordinator events without repository roots failed admission. Sign a minimal kind-0 NIP-05 bot profile at startup — per NIP-24 `name` is always set, here to the scheme-less public URL — alongside a single unmarked kind-10002 relay entry. An operator-customized profile is kept and never overwritten, and no identity event — locally stored or freshly generated — is published before the local database and at least one user-index relay have been successfully checked for that kind, so a database wiped and reseeded during an index outage can never displace a customized profile surviving on the indexes. Every send is preceded by a per-relay re-check: an identity found on an index relay is adopted locally, where replaceable-event semantics keep the newest copy, and is never overwritten, so publication only fills gaps on index relays that individually confirm they hold none; propagating a profile update onto an index that already has one is left to the operator's own client. A kind with no local copy is not even seeded until a reachable user-index relay confirms it holds no identity of that kind. Publication never blocks startup, retries transient failures with a capped backoff, and stops on terminal protocol rejections. With no user-index relays configured, missing kinds are seeded locally right away. In private mode (GRASP-08) identity events are seeded and served locally but never published, so a private relay does not advertise its existence. Trust valid owner-signed events only for kinds without a dedicated admission policy, such as ngit-ci coordinator advertisements that carry no repository root tag. Owner-signed NIP-34 announcements, state events, and PRs run the normal announcement validation, ref alignment, and purgatory git-data handling like any other author, and the relay's own kind 0/10002 identity is always accepted. The NIP-09/NIP-62 deletion gate still runs before any owner acceptance, so replaying a retracted owner event cannot undo its tombstone, and owner deletion/vanish requests keep their lifecycle handling. Because the event blacklist cannot block the owner key, rotating the key is the only remediation if it is compromised; this is documented. NGIT_DOMAIN is assumed to be the documented bare public authority: loopback authorities use ws and other hosts advertise wss, with bare IPv6 authorities bracketed. The test fixture reuses relay-owner keys across TestRelay::restart, and gains caller-provided keys, a private-mode member setup, and explicit user-index relay lists; MockRelay can start pre-seeded so a "recovering" index deterministically holds prior state. Identity retry intervals honor the existing NGIT_TEST fast-timer convention. No new configuration switches or ngit-ci changes are included. Includes rustfmt fixes for src/nostr/policy/announcement.rs and tests/private_mode.rs, which arrived on master unformatted and would otherwise fail the workspace format gate. Validated with rustfmt, strict workspace Clippy, the relay_identity and private_mode integration binaries, and the full workspace test suite. Individual sync/grasp06 integration tests fail intermittently under parallel full-suite load, each passing in isolation and on rerun; the same intermittent failures reproduce on origin/master without these changes.
