+
+## Where things are
+
+- Project: `/home/avi/Projects/Nostr_Keynctr`
+- Git repo: `master` @ `8bce428` ("Updates card: scan npm/cargo deps, surface
+  security advisories, install compatible updates"). Before it: `55a49b4`
+  (feed profile filter), `3dfd15f` (checkpoint), `b001b3c` (publish latency).
+- Working tree is **clean** apart from this checkpoint update, which is committed right after.
+
+## What was completed
+
+1. **Updates card in Settings (2026-08-24, `8bce428`).** New **Updates** section
+   on the Settings screen with two buttons:
+   - **Check for updates** — scans without changing anything:
+     `npm outdated --json` + `npm audit --json` (frontend) and
+     `cargo update --dry-run` (Rust). Known security advisories are listed
+     first with severity badges (critical/high → danger, moderate → warning);
+     outdated npm packages and Rust crates are listed with current → available
+     versions.
+   - **Install updates** — applies compatible (non-breaking) updates:
+     `npm audit fix`, then `npm update`, then `cargo update`. Reports what was
+     applied and reminds that a **rebuild + restart** is required to load them.
+   - First real scan found 20 advisories (2 critical: tar, vitest; several high
+     in the Electron build chain), 18 outdated npm packages, 42 outdated crates.
+2. **Backend:** new `src/updates.rs` module (parsers unit-tested; commands run
+   with timeouts and never touch secret material). IPC methods `update_check`
+   and `update_apply`, dispatched outside the state lock so slow installs never
+   block other requests. Electron allowlist extended; backend round-trip cap
+   raised 120 s → 300 s to fit cold-cache installs.
+3. Optional hardening noted in-app: installing `cargo-audit` adds RustSec
+   advisory scanning for the Rust side (currently not installed on this machine;
+   the app says so under Notes when absent).
+
+## Commits added most recently
+
+- `8bce428` Updates card: scan npm/cargo deps, surface security advisories, install compatible updates
+
+## Verification commands run (all green)
+
+Rust (repo root):
+
+```
+cargo test            # 112 passed; 0 failed (8 new updates tests)
+cargo clippy --all-targets   # only pre-existing warnings in src/profiles.rs
+cargo fmt --check     # clean
+cargo build --release # success
+# end-to-end: echo '{"id":1,"method":"update_check"}' | ./target/release/keynectr serve
+# returned real advisories/outdated lists for this machine
+```
+
+Frontend (`frontend/`):
+
+```
+npm test              # 14 files, 91 tests passed (4 new Settings tests)
+npm run typecheck     # clean
+npm run lint          # 0 errors
+npm run format:check  # clean
+npm run build         # vite build success
+npm run electron:build  # tsc electron main success
+```
+
+## How to use / reproduce
+
+GUI: `cd ~/Projects/Nostr_Keynctr/frontend && npm start` → **Settings →
+Updates → Check for updates**, review the list (security first), then
+**Install updates**. Afterwards rebuild and relaunch:
+
+```bash
+cd ~/Projects/Nostr_Keynctr && cargo build --release
+cd frontend && npm run build && npm start
+```
+
+CLI equivalent:
+
+```bash
+cd frontend && npm audit fix && npm update
+cd .. && cargo update
+```
+
+## Notes & next steps
+
+- `Install updates` only applies semver-compatible bumps. Major version jumps
+  shown by the check (e.g. electron 33 → 43, eslint 9 → 10) still need manual
+  attention — deliberate, to avoid breaking the app silently.
+- Consider running the first real "Install updates" soon: 2 critical npm
+  advisories were found (tar, vitest dev chain) plus high-severity Electron
+  packaging tools.
+- Install `cargo-audit` (`cargo install cargo-audit`) for RustSec coverage; the
+  card picks it up automatically once present.
+- Possible follow-ups: CLI `updates` subcommand; auto-check on startup behind a
+  setting.
+- Relay health (earlier today): damus.io 503, nostr.band WS handshake timing out.
