+# Checkpoint — cron hygiene: lockfile refresh committed + pushed (2026-10-01 evening)
+
+## Where things are
+- Project: `/home/avi/Projects/Keynctr`, branch `master` @ **`41d4a60`**
+  ("chore(deps): lockfile refresh from update_apply"). Pushed —
+  `git ls-remote origin master` = `41d4a60` verified.
+- Working tree: clean for tracked files (always-untracked: COSMIC_THEME.md,
+  icon jpeg, deferred/).
+- Release binary: 15:23 build from the d09c4ec tree (lockfiles are
+  dependency-resolution only; no backend source changed since). NOTE: the
+  live `keynectr serve` (pid 356510) started 09:59, BEFORE the 15:23 rebuild —
+  relaunch the app to pick up Step 4.
+
+## What was done (user-facing)
+- No new feature this run. Evening cron checked the Amber NIP-46 pairing
+  problem from the standing brief: it remains CLOSED. `profiles_vault.json`
+  holds 3 `nip46_connections` + matching nip46_client rows (latest pairing
+  2026-09-28 10:23, "Amber"); the debug capture dir `~/Tools/keynctr-debug/`
+  and `/tmp/keynctr-el*.log` no longer exist, and no parse-failure evidence
+  has appeared since the Sep 28 closure. The payload-coercion fix from the
+  brief is already contained in shipped history (superseded by 5b60ae3 chain).
+- Committed the stray lockfile refresh left by the in-app update flow
+  (yoke-derive 0.8.3→0.8.4, npm tree refresh) so the tree is clean.
+
+## Commits this session (newest first)
+- `41d4a60` chore(deps): lockfile refresh from update_apply
+- (checkpoint update follows this section's commit)
+
+## Verification (all green, 2026-10-01 ~20:07)
+- `cargo test` → 227 unit + 6 e2e, 0 failed · `cargo clippy --all-targets` → 0 warnings
+- `cargo fmt --check` clean · frontend `npm test` → 148/148 (19 files) · `npm run typecheck` clean
+
+## Outstanding / next steps
+- User relaunch of the app (live serve predates the 15:23 Step 4 rebuild).
+- Live pass: approval-time kind editor with Amber; rename npub1p437 + Publish name;
+  publish kind-0 to primal/damus; KDF live check on real unlock.
