-# Checkpoint — NIP-46 signer handshake fix (2026-08-24)

+
+## Where things are
+
+- Project: `/home/avi/Projects/Nostr_Keynctr`
+- Git repo: `master` @ `1c428a9` ("DRY: single parallel relay fan-out for notes
+  and metadata"). Before it: `64ad94d` (NIP-46 handshake fix), `b21678f`/
+  `ae84526` (checkpoints), `dd50b24` (Aurora rename).
+- Working tree: clean apart from this checkpoint update. `concept3.svg` deleted
+  and `KeynectrAppIconPossibility02.jpeg` untracked remain as the user had them.
+
+## What was completed
+
+1. **R1 DRY refactor (`1c428a9`).** The parallel relay send block (~55 lines:
+   JoinSet per-relay sends, 6 s timeout, indexed outcome collection,
+   disconnect, succeeded/failed split) existed twice — in
+   `publish.rs::publish_with_keys` and `profiles.rs::publish_metadata_async`.
+   Now one `pub(crate) publish::send_to_all_relays(client, urls, event, noun)`
+   serves both; callers keep their distinct add-relay policies (note path
+   aborts on add errors, metadata ignores them) so behavior, error strings,
+   and public APIs are unchanged. Removed duplicate constant
+   `METADATA_SEND_TIMEOUT`, dead helper `failure_for`. Net −49 lines.
+2. Deliberately NOT done (pending approval): R2 shared client-bootstrap
+   helper, R3 modal save-lifecycle hook (frontend), R4 shortHex/shortenNpub.
+
+## Commits added most recently
+
+- `1c428a9` DRY: single parallel relay fan-out for notes and metadata
+
+## Verification commands run (all green)
+
+Rust: cargo fmt --check clean; clippy only pre-existing profiles.rs warnings;
+cargo test 113 passed; release binary rebuilt.
+Frontend (untouched, suite rerun): npm test 92 passed; typecheck, lint,
+format:check, electron:build, vite build all clean.
+
+## How to use / reproduce
+
+No user-facing change; note and metadata publishing behave exactly as before.
+Any future change to relay-send policy now happens in one place:
+`send_to_all_relays` in `src/publish.rs`.
+
+## Notes & next steps
+
+- R2–R4 from the DRY audit remain unimplemented by request.
+- Relay health today: nos.lol 502, nostr.wine 403, nostr.l484.com needs
+  NIP-42 auth, nostr.band unreachable; primal/mom/soloco healthy.
