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 The payload-coercion fix from the brief is already contained in shipped history (superseded by 5b60ae3 chain).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.

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.

Checkpoint — Step 4 finished: interactive kind scope at approval (2026-10-01)

Where things are

Project: /home/avi/Projects/Keynctr, branch master @ d09c4ec ("feat(signer): interactive kind scope in the approval prompt (Step 4 finish)"). Previous: 8ffeb42 + d1622a0 (checkpoint updates, pushed), 83f5940 (placeholder kind-0 fix), e8d2abb (grant kind-editing UI).
Working tree: clean for tracked files (always-untracked: COSMIC_THEME.md, icon jpeg, deferred/). Push status in Next steps.
Release binary rebuilt from d09c4ec at 13:30 (real 30s build, mtime verified).

What was completed (user-facing)

Step 4 remainder — kind scope chosen AT approval time:

Signer screen and Signer Mode screen: on a pending sign_event request, "Always allow…" opens an inline kind editor prefilled with the request's own event kind; Allow records the grant with exactly the edited kinds (sorted+deduped, empty = all kinds = explicit broadening), Cancel leaves the request pending. Non-signing methods keep the plain "Always allow" button (no kind dimension).
Backend: Nip46Approve/SignerApprove gained grant_kinds (serde(default) Option<Vec<u16>> — old payloads stay valid). respond_to_approval_with_always(.., grant_kinds): Some(list) stores the edited scope verbatim; None keeps the old fallback (kind of the request being approved). Legacy vault rows untouched.
nip46_status_as_bunker_json now includes each pending request's details, so the legacy Signer screen can prefill the editor too.
Shared parseKindsInput() in lib/permissions.ts (used by both the approval editor and the existing grant editor); grant editor refactored onto it — behaviour unchanged.
Latent bug fixed: AppProvider.signerApprove dropped the always argument, so the legacy "Always allow" button never recorded a grant.

d09c4ec feat(signer): interactive kind scope in the approval prompt (Step 4 finish)
8ffeb42 docs(checkpoint): 8070dfc..d1622a0 pushed to origin/master
(earlier today) d1622a0, 83f5940, e8d2abb — see checkpoint below

Verification (all green, 2026-10-01)

cargo test → 227 unit + 6 e2e, 0 failed · cargo clippy --all-targets → 0 warnings
cargo fmt --check clean · cargo build --release rebuilt 13:30 from d09c4ec
frontend: vitest 148/19 files (6 new: 3 approval-editor tests, 3 parseKindsInput units); typecheck, lint, format:check, build, electron:build all green.

How to verify in the app

Fully quit and relaunch Keynctr (new backend, 13:30).
Have the connected app request a signature → Signer screen → "Always allow…" on the pending request → edit kinds → Allow. The "Always-allow permissions" card shows the scoped grant; a later request of an UNcovered kind prompts again.
e2e-mechanics are covered by the 3 new SignerScreen tests.

Next steps

PUSHED 2026-10-01 after this checkpoint (see git remote readback); token per-use, not stored (revoke when convenient).
User live pass: relaunch, rename npub1p437… + Publish name, try the new approval-time kind editor with Amber.
Optional: remove /tmp/kn-base worktree when done.

Checkpoint — placeholder kind-0 fix + grant editing UI (2026-10-01)

Where things are

Project: /home/avi/Projects/Keynctr, branch master @ 83f5940 ("fix(profiles): never treat placeholder kind-0 as a real display name").
Working tree: clean for tracked files (always-untracked: COSMIC_THEME.md, icon jpeg, deferred/).
Pushed to origin/master (see Next steps): remote head == d1622a0.

What was completed (user-facing)

Grant kind-editing UI (e8d2abb): the Signer screen's "Always-allow permissions" card now edits each grant's event-kind scope inline (Edit → comma-separated kinds → Save/Revert). Backed by the signer_grant_update RPC from d7cf2a5.
Profile-name fix (83f5940): placeholder "My Profile" names no longer stick. Verified live: npub1p437…'s kind-0 on purplepag.es/damus says "My Profile" (ts 1789050653) — an early build auto-published the empty-label default as new accounts' kind-0, and pairing enrichment + backfill then copied that poisoned value over typed names forever. Now:
- shared profiles::network_display_name() rejects blank AND placeholder names fetched FROM the network (unit-tested);
- create/import never auto-publish a generic placeholder as kind-0;
- import falls back to the shortened npub instead of "My Profile".

Verification (all green, 2026-10-01)

cargo test → 227 unit + 6 e2e, 0 failed · cargo clippy --all-targets → 0 warnings
cargo fmt --check clean · cargo build --release rebuilt 10:48
frontend: npm test 142 passed; typecheck, lint, format:check, build, electron:build green. (Full-suite failures seen earlier today were load-induced 5s timeouts on a busy box — passed on quiet reruns.)

How to verify in the app

Fully quit and relaunch Keynctr (new backend, 10:48).
For npub1p437…: Profiles → rename → Publish name (pushes a clean kind-0 network-wide). The backfill will no longer overwrite it with "My Profile".
Signer screen → Always-allow permissions → Edit a grant's kinds → Save.

Next steps

PUSHED 2026-10-01: 8070dfc..d1622a0 on origin/master, verified by ls-remote readback (remote head == local head). Token was per-use, not stored (revoke when convenient).
Optional: remove /tmp/kn-base worktree when done.

Checkpoint — grant kind-editing backend (2026-09-30, session stopped mid-Step-4)

Where things are

Project: /home/avi/Projects/Keynctr, branch master @ d7cf2a5 ("feat(signer): grant kind-editing backend (vault + IPC + api plumbing)"). Previous: ec8b515 + aef47dd (profile-relay queries, checkpoint above), eea6f0e (white launcher icon), abc2781 (one-click update script).
Working tree: clean for tracked files. Untracked intentionally NOT committed: COSMIC_THEME.md, KeynectrAppIconPossibility02.jpeg, deferred/SignerConnectionPanel.tsx.wip/.
origin/master behind: local ahead by 4 commits (push still blocked — no Forgejo credentials stored; needs a token via the one-shot extraHeader method).

What was completed (this checkpoint)

Grant kind-editing backend — Step 4 remainder, first half (session was stopped by the user mid-build; the UI half is NOT started):

vault.rs: Vault::update_signer_grant_kinds(app, method, kinds) — replaces a standing grant's kind scope, normalised (sorted + deduped). Empty list = "all kinds" (same representation legacy grants use), so broadening is explicit, never from omission. Unknown (app, method) returns false, changes nothing. New unit test signer_grant_kinds_can_be_edited.
ipc.rs: Request::SignerGrantUpdate { app_pubkey, grant_method, grant_kinds } (field names avoid the internal method tag; kinds use serde(default) so legacy payloads stay valid) + handler that saves the vault only when a grant actually changed.
Frontend plumbing only, NO UI yet: api.signerGrantUpdate, the AppProvider context type + callback + value/deps lists, and the signer_grant_update case in fakeBackend.ts mirroring the backend normalisation.

d7cf2a5 feat(signer): grant kind-editing backend
ec8b515 docs(checkpoint): profile-relay queries @ aef47dd
aef47dd fix(feed): query profile relays for kind-3 follow lists and kind-0 metadata (WIP of the previous dead session, verified + dedupe bug fixed: trailing-slash normalising via a seen-set)

Verification (2026-09-30 @ `d7cf2a5`)

cargo test -> 226 unit passed, 0 failed (e2e 6 green at aef47dd run).
cargo clippy --all-targets -> 0 warnings; cargo fmt --check clean.
cargo check green. NOTE: release binary at target/release/keynectr was built at aef47dd, NOT d7cf2a5 — rebuild before shipping the new RPC.
frontend: npm run typecheck clean; npm test -> 139 passed (19 files). No new UI tests yet (no UI yet).

How to resume

NEXT UNIT (was next when stopped): the Signer-screen grant editor — inline kind editing on the "Always-allow permissions" card in frontend/src/screens/SignerScreen.tsx (grants list, lines ~243-268): edit kinds for a sign_event grant -> signerGrantUpdate(app, method, kinds); include an explicit "all kinds" option (empty list), Revoke stays as is. Add SignerScreen.test.tsx cases against the fakeBackend signer_grant_update case, then the full gates + release rebuild + checkpoint update.
GUI dev loop: cd frontend && npx vite --port 5173, then NOSTR_GUI_DEV_URL=http://localhost:5173 KEYNCTR_ENABLE_GPU=1 npx electron .
Push when a token is available: git push origin master (4 ahead).

Outstanding / next steps

Grant editor UI (above) — second half of Step 4 remainder.
Live pass: "My contacts" with the rebuilt backend (aef47dd fix).
Push 4 commits to Forgejo.

Checkpoint — profile-relay queries for contacts + metadata backfill (2026-09-30)

Where things are

Project: /home/avi/Projects/Keynctr, branch master @ aef47dd ("fix(feed): query profile relays for kind-3 follow lists and kind-0 metadata"). Previous: eea6f0e (white monochrome launcher icon), abc2781 (one-click update script), 7891ccc (Step 7 rename/hygiene, checkpoint 33ab4fe).
Working tree: clean for tracked files. Untracked intentionally NOT committed: COSMIC_THEME.md, KeynectrAppIconPossibility02.jpeg, deferred/SignerConnectionPanel.tsx.wip/.
Release binary rebuilt at aef47dd 2026-09-30 14:18 (verified by mtime after touching the changed sources — not a cache hit).

What was completed

Profile-relay lookup for profile-scoped data (finishes the empty "My contacts" diagnosis on the network side): kind-3 follow lists and kind-0 metadata usually live on profile/outbox relays — purplepag.es aggregates them network-wide — not on the user's note read relays. Now:

feed.rs: PROFILE_RELAYS = ["wss://purplepag.es"] plus profile_lookup_relays(settings) = enabled relays + profile relays, de-duplicated with trailing-slash normalising (a user entry wss://purplepag.es/ no longer doubles the always-on entry — the WIP version of this failed its own test; rewritten via a HashSet seen-set). contact_pubkeys (kind-3 fetch) now queries that set; notes queries deliberately keep using only enabled relays.
ipc.rs backfill loop: kind-0 fetch also uses profile_lookup_relays, and the candidate filter dropped the SignerMode::Nip46Client restriction — any row still wearing a placeholder gets a real name, local keys included.
profiles.rs: GENERIC_PAIRING_LABELS now includes "My Profile" (normalise_label's empty-input default), so locally created placeholder rows are backfilled too. Test updated: user renames still never overwritten.

aef47dd fix(feed): query profile relays for kind-3 follow lists and kind-0 metadata (includes the fmt fix + dedupe rewrite of the WIP)
(this checkpoint commit)

Verification

cargo test -> 225 unit + 6 e2e passed, 0 failed.
cargo clippy --all-targets -> 0 warnings. cargo fmt --check -> clean.
cargo build --release -> rebuilt at aef47dd (binary mtime 14:18).
No frontend files touched -> frontend gates not applicable.

How to resume / reproduce

CLI ground truth for the contacts fix: target/release/keynectr feed --contacts 20 with the active key that has a follow list published anywhere on the network — rows should now appear even when purplepag.es is not in the user's read relays.
GUI: cd ~/Projects/Keynctr/frontend && npx vite --port 5173 then NOSTR_GUI_DEV_URL=http://localhost:5173 KEYNCTR_ENABLE_GPU=1 npx electron . (running windows need a relaunch/rebuild to pick up the new backend).
Backfill trace: grep -a 'auto-name' ~/Tools/keynctr-debug/pairing-trace.log.

Outstanding / next steps

Live pass: reopen "My contacts" in the GUI with the rebuilt backend and confirm the feed populates for the account that has follow lists on profile relays.
Step 4 permissions UI follow-ups (interactive grant editing in the approval modal) — the only buildable step left from the plan.
Live pass: KDF migration on a real unlock + second-Amber account switching.

Checkpoint — stdin EAGAIN fix, accent theme, identity backfill (2026-09-28 evening)

Where things are

Project: /home/avi/Projects/Keynctr, branch master @ fac4ba3 ("feat(desktop): launch from the applications list (folio-style)"). Previous: d792a72 (Archipelago uses the reference artwork as canvas), 4d0df31 (Archipelago theme tokens, first pass). 5b60ae3 (persistent identity backfill for generic pairing labels), a6182e3 (iOS blue accent for Workshop Dark + custom accent setting), 9770f46 (stdin blocking-thread reader — EAGAIN crash fix), 6bff188 (docs), dcc701f (no-restart self-update).
Working tree: clean for tracked files. Untracked intentionally NOT committed: COSMIC_THEME.md, KeynectrAppIconPossibility02.jpeg, deferred/SignerConnectionPanel.tsx.wip/.
Release binary rebuilt 2026-09-28 ~12:40 (from the 4d0df31 tree).
origin/master is at a6182e3; local is 1 commit ahead — push still blocked (no Forgejo token stored for this session; HTTPS asks for credentials).

Pairing problem status — RESOLVED (live evidence)

~/.local/share/keynectr/profiles_vault.json now carries 3 persisted nip46_connections rows with matching signer_mode: nip46_client profile rows (created Sep 25, Sep 27, and Sep 28 10:23). The Sep 28 pairing happened on the current build: Amber's connect event parses, the handshake completes, and the profile row persists — the original "Amber says connected but no row appears" failure no longer reproduces.
The Sep 28 row is the active profile. Its label is still the generic "Amber" because the paired account has not published kind-0 yet; 5b60ae3 backfill re-checks every ~2-5 min while the backend runs and will rename it when metadata appears. No further parse-side work outstanding.

What was completed (this checkpoint's commits)

9770f46 stdin EAGAIN crash fix — keynectr serve treated a transient EAGAIN on the Electron pipe as fatal ("Rust backend exited unexpectedly code 1"). Dedicated blocking-thread reader + mpsc; verified live with a 200-line request stream.
a6182e3 custom accent color — iOS blue accent for Workshop Dark plus a user-settable accent color.
5b60ae3 persistent identity backfill — slow-cadence loop in serve() re-fetches kind-0 for Nip46Client rows still wearing generic "Amber"/"Remote Signer" placeholders; user renames never overwritten; locked vaults skipped; network off-lock, 90 s budget per identity.
4d0df31 Archipelago theme — new archipelago theme from the user's synthwave reference art: teal-navy dusk canvas, coral (#f0685c) scanline sun glow + pink cloud banks + faint horizontal scanlines on .main (fixed attachment), glassmorphic blur on cards/sidebar, white logo filter. Settings -> Appearance -> "Archipelago - Sunset Sea".
d792a72 Archipelago artwork canvas (v2) — first pass was abstract washes and did not match the reference; replaced with the actual illustration (frontend/public/archipelago-bg.jpg) cover/fixed under a dark scrim on .main, translucent blur-glass cards + sidebar, light hairline borders, coral accent. This is what the reference mock shows.
fac4ba3 applications-list launcher — launch-keynctr.sh + ~/.local/share/applications/keynctr.desktop (validated); GPU env set for Hyprland; single-instance lock focuses the existing window. Verified by gtk-launch twice: one window, correct WM class.

Verification (2026-09-28 evening cron pass)

cargo test → 221 unit + 6 e2e passed, 0 failed.
cargo clippy --all-targets → 0 warnings. cargo fmt --check → clean.
frontend: npm test → 139 passed (19 files); typecheck, lint, format:check all clean.

CLI backend: target/release/keynectr serve (spawned by Electron).
Push pending commit when credentials are available: git push origin master.

Outstanding / next steps

Live confirmation of the backfill rename: pair/keep a fresh Amber account with no kind-0, publish kind-0 from Amber, confirm the Keynctr row renames itself within ~5 min without restarting the app.
Step 4 permissions UI follow-ups (interactive grant editing in the approval modal) — the only buildable step left.
Live pass: KDF migration on a real unlock + second-Amber account switching.

Checkpoint — Step 7 rename/hygiene + Forgejo push restored (2026-09-30)

Where things are

Project: /home/avi/Projects/Keynctr, branch master @ 7891ccc ("docs: Step 7 rename/hygiene pass"). Previous: c553dd5 (KDF upgrade m=64MiB/t=3 + transparent migration, Sep 30), 5e91914 (launcher), theme commits, identity backfill.
Forgejo push unblocked: token supplied per-use via git -c http.extraHeader="Authorization: Bearer <token>" push origin master (token supplied in chat, NOT stored anywhere — revoke when convenient). a6182e3..c553dd5 pushed; remote master verified == local. Token is single-use-per-invocation; re-ask for it next push unless the user stores one.
Step 7 done in 7891ccc: frontend/package.json homepage -> https://git.atitlan.io/avi/Keynctr; README retitled Keynctr, all [YOUR_FORGEJO_INSTANCE_URL]/<OWNER>/<REPO> placeholders resolved, clone dir + packaged binary name fixed (keynectr), data-dir default ~/.local/share/keynectr (code auto-migrates the legacy dir), stale test counts refreshed (cargo 225 unit + 6 e2e; npm 139 tests / 19 files), project layout updated (audit/bunker/feed/updates, signer/ dir, Feed + SignerMode screens). PRODUCT.md data-dir corrected.

Outstanding / next steps

Live pass (user): KDF migration on a real unlock; second-Amber switch + backfill rename confirmation; publish kind-0 to primal/damus.
Step 4 remainder: interactive grant editing in the approval modal.
No CI workflow yet — .forgejo/workflows/ci.yml badge stays commented.

Checkpoint — permissions UI + updater fix + Workshop theme (2026-09-27 night)

Where things are

Project: /home/avi/Projects/Keynctr, branch master @ add956a ("feat(theme): add Workshop theme — Cybernetic Workshop identity from Moi DESIGN.md"). Previous: 15fa331 (updater-run dependency bumps, clears the high js-yaml advisory), fa59b63 (updater PATH fix), adbc7c2 (permissions UI), 98593cb (checkpoint), c89b31a.
Working tree: clean for tracked files. Untracked intentionally NOT committed: COSMIC_THEME.md, KeynectrAppIconPossibility02.jpeg, deferred/.
Release binary rebuilt at add956a (2026-09-28, after 3m01s real build).
NOTE: a running Electron app still serves the OLD backend + stale dist/ until relaunch; the running serve predates these commits. The user's "Update problem: The Rust backend exited unexpectedly (code 1)" screenshot came from that old build; update_apply verified green end-to-end on the new binary (all three steps applied).

What was completed

Permissions are visible (Step 4, first slice). Nip46Status now carries the connection's declared perms= grant list and expiry. The Signer Mode screen shows a Permissions panel on a live session: one row per granted method ("Sign events — kinds 1, 30023"), or a plain statement that the signer app (Amber) approves every request when no grant list was declared. frontend/src/lib/permissions.ts holds the shared label formatters.
"Always allow" is now kind-scoped (was: method-wide, too broad). A sign_event grant records the kind of the request the user actually approved; a kind-1 grant never covers a kind-3 request — uncovered kinds fall back to the approval prompt. Legacy kind-less grants keep their all-kinds meaning (stored vaults keep working; new grants are never created kind-less). Enforced in BOTH bunker.rs (bunker mode) and nip46_client.rs (client mode) via Vault::has_signer_grant(peer, method, event_kind). The Signer screen's grants list renders the human label with kind scope.
Check-for-updates fixed. The Electron-spawned backend inherited the desktop launcher's PATH (no ~/.cargo/bin, no mise/asdf shims), so npm/cargo "didn't exist". updates.rs::run() now appends the well-known per-user tool dirs to the inherited PATH (inherited wins on conflicts; missing dirs ignored). Verified live under env -i PATH=/usr/bin:/bin: update_check returns a full report.

Electron shell stays up; main-process changes still need one manual relaunch; packaged builds report bundle replacement.

Verification (all green at `fa59b63`)

Rust: cargo test 219 unit + 6 e2e (NEW: signer_grants_are_kind_scoped, two augmented_path tests); cargo clippy --all-targets 0; cargo fmt --check clean; cargo build --release rebuilt 22:43.
Frontend: npm test 135 (10 new: permissions.test.ts unit + 2 SignerModeScreen permission-panel tests), typecheck, lint, format:check, build, electron:build all green.

Deferred / next steps

Live eyeball: relaunch the app, pair with a perms=-carrying client (or Amber) and check the Permissions panel; approve kind-1 "Always allow", then send a kind-3 request and confirm it PROMPTS (kind scope).
Two-account live pass from the previous checkpoint still open (pair account B in Amber, switch back and forth).
Publish kind-0 to primal/damus (one Amber approval).
Step 4 remainder (if wanted): interactive grant editing in the approval modal (approve-with-narrowing UI); today the modal is Approve / Always allow (kind-scoped) / Reject.
Step 5 (KDF upgrade m=64MiB/t=3 + vault header versioning), Step 6 (undo history), Step 7 (rename/hygiene incl. homepage URL).

Checkpoint — multi-account signer switching (Option A) (2026-09-27 eve)

Where things are

Project: /home/avi/Projects/Keynctr, branch master @ c89b31a ("feat(nip46): pair a second signer account — park the live session, switch re-dials it"). Previous: 1b4655c (checkpoint), 332ab64.
Working tree: clean for tracked files. Untracked intentionally NOT committed: COSMIC_THEME.md, KeynectrAppIconPossibility02.jpeg, deferred/.

What was completed (user-facing)

You can now add a second Amber account. Pairing a new signer while one is connected no longer says "Already connected — disconnect first": the current session is PARKED (kept restorable, never revoked) and the new account pairs.
Switching profiles switches signer accounts. Click a profile in Profiles: if it has a saved signer session, the live one is parked and that profile's session is re-dialed automatically (no scan, identity guard still enforced). Local-key profiles leave the signer alone.
Cancel on the QR is safe. Leaving the QR view cancels only the pairing attempt and brings the parked session back (new nip46_cancel_pairing IPC; the old path revoked).

One session is live at a time (Amber signs one active account anyway); all others stay saved and switchable.

Commits added

c89b31a feat(nip46): pair a second signer account — park the live session, switch re-dials it

Verification (all green at `c89b31a`)

Rust: cargo test 216 unit + 6 e2e (NEW: two fake Ambers on one relay — B's pairing parks A unrevoked with client key intact; switch back re-dials A and signs; no-op switch; local profile untouched; B restorable). cargo clippy --all-targets 0 warnings; cargo fmt --check clean; cargo build --release rebuilt (binary mtime Sep 27 21:00).
Frontend: npm test 125 passed; typecheck, lint, format:check clean; npm run build + electron:build green.

Resume / reproduce

GUI: relaunch the app (or restart the backend) to pick up the new release binary. Profiles -> click another paired profile -> log shows restoring session + identity check on restored session: PASS.
Add account B: Create Profile -> Sign in with Amber -> switch to account B IN AMBER -> scan. Account A stays restorable.
e2e: cargo test --test nip46_e2e (6 tests, loopback relay only).

Outstanding

LIVE two-account eyeball by the user (pair account B from a second Amber profile, switch back and forth) — e2e proves the mechanics, a real-device pass confirms it end-to-end.
Live "Check for updates" failure is an ENVIRONMENT issue, not a bug: the updater shells out to npm outdated/cargo update in the source tree; the spawned backend's PATH lacks npm/cargo (Electron-launched process), so it errors. Fix options: bake a login-shell PATH into the updater or surface a clearer message. Not started.
Publish kind-0 to primal/damus (one Amber approval); Step 4 permissions UI; KDF upgrade (Step 5); rename pass (Step 7).

Release binary rebuilt at 332ab64 (mtime Sep 26 20:34, real 22s compile, not a cache hit).

What was completed

LIVE PUBLISH CONFIRMED (was the last open item) — el.log shows three sign_event responses ~19:50 Sep 25 and relay probes confirm kind:1 notes (id 5191172d01f9…, fe9a256f597f…, text "test" + image) from npub1qn0w4… accepted on primal/damus/snort/nos.lol at exactly those timestamps. End-to-end Amber signing works.
False alarms retired: the repeated "restored signer answered as a different account" and duplicate "auto-name attempt" lines in pairing-trace.log were E2E TEST traffic (wrong-identity refusal test
- loopback auto-name loop), not live Amber failures — each bogus npub appeared exactly at test-run times (17:09 rebuild, 20:07 suite).
Trace gating fix (332ab64): fail() and the background auto-name traces now check live_relays() like every other site. Verified by measurement: e2e suite run leaves pairing-trace.log byte-identical (was 240 lines before, 240 after).
Live vault pruned (not in git): dropped the legacy fac852dc… connection row (15:37 pairing, predates client-key persistence, superseded by 19:35 4148a9a1… pairing) so startup restore can't waste a re-dial on a keyless row. Backup: profiles_vault.json.backup-cron-20260926. Done with backend down.

Verified this session

cargo test: 216 unit + 5 e2e green. clippy --all-targets: 0 warnings. cargo fmt --check clean. cargo build --release rebuilt at 332ab64.
Frontend untouched this session (no npm run needed).
Serve smoke test on the REAL vault (backend was down): startup restore fires "restoring session: peer=4148a9a1… client pubkey=64ea18e8…" (the persisted key from the 19:35 pairing), relays connect, no errors. Full handshake needs Amber online — user test.
kind-0 'web5osint' confirmed live on nos.lol; profile row already carries the name + picture in the vault.

Outstanding / next user steps

One scanless restart check: launch the GUI with Amber online and watch for "identity check on restored session: PASS" without scanning (restore now targets only the restorable 4148a9a1 row).
Optional: publish kind-0 to primal/damus too so naming doesn't depend on nos.lol alone (needs one Amber signature).
reminder: pkill patterns matching their own launch string kill the cron shell — resolve PID by full binary path first.

Checkpoint — auto-naming hardened (2026-09-25 eve)

What changed since the label-step checkpoint

UI: pairing label step REMOVED (user friction: prefilled 'Amber' needed letter-by-letter deletion). One click 'Sign in with a signer app (Amber)' → QR. Seed label 'Amber'; real name comes from kind-0. (fc2fe93)
Backend: auto-name enrichment now retries 4x/20s apart with 75s budget and per-attempt pairing_trace lines (bc736ff), after live proof that nos.lol — the ONLY relay holding this account's kind-0 ('web5osint') — intermittently 502s EVERY client (any UA; nostr-sdk and raw websockets alike; worked 16:29, dead 16:40+). Single-shot fetch + flaky relay = permanently generic label; retries fix that.

Verified

fetch_profile_metadata bisected per relay: only nos.lol has the kind-0; all others return None (account metadata was only ever published there).
216 unit + 5 e2e green; clippy 0; fmt clean; release rebuilt bc736ff.
frontend 125 tests green at fc2fe93.

Open

Profile will auto-rename to 'web5osint' on the next successful restore once nos.lol recovers (retry loop logs 'auto-name: kind-0 fetched').
Consider publishing the account's kind-0 to primal/damus too so naming doesn't depend on one relay (needs one Amber signature; user action).

SESSION RESTORE LIVE-VERIFIED against real Amber at 01ce5de: log shows restoring session -> secret validation SKIPPED (restore) -> get_public_key -> identity check PASS -> Connected, no scan. (Amber answered a plain 'ack' here, not 'true' — the restore path now accepts any ack shape and trusts the re-proved identity.)
Remaining live proof: one publish/note approved in Amber within the 120s leash (fresh pairing at 15:37 already exercised sign? — the last_publish.json entry from 10:57 was BEFORE the fresh pairing; the fresh profile has not published yet).

What was completed

Restore secret-echo fix (01ce5de): session restore failed 100% against real Amber — the re-dial resent the pairing secret and the client demanded an echo, but an already-approved signer legitimately answers without re-echoing (echo = initial-pairing possession proof only). ConnectUri gained a restore flag (only reactivate_saved_sessions sets it): restore skips the echo and relies on expected_identity in adopt_identity; fresh pairings still fail closed on a wrong echo. e2f model updated: run_fake_amber now mirrors Amber ack shapes and the restore test seeds a pairing secret (fails without the fix). cargo test 216 unit + 5 e2e green; clippy 0; fmt clean; release rebuilt at 01ce5de; backend restarted and LIVE restore verified.

What was completed this session

Add-profile choice (5b13162): clicking "Add profile" now opens a choice modal: "Sign in with a signer app (Amber)" shows the nostrconnect:// pairing QR inline, polls signer status every 2s, and confirms "Amber is now your signer!" when the handshake lands (cancel aborts mid-pairing). "Create a new key on this computer" keeps the old local-key form with a Back step. Previously the Amber QR was only reachable via the sidebar Signer Mode screen, so the expected entry point hid the main flow.

Verification: frontend 125 tests passed (CreateProfileModal suite rewritten: choice step, QR start, connected-poll confirmation, cancel-abort; App.test dialog title updated), npm run typecheck, npm run lint, npm run format:check, npm run electron:build, npm run build all green. Rust untouched.

Release binary: rebuilt at a6a4e6f (test-only commit; same code as 0982dad for the app itself). Restart Electron before retesting.

What was completed this session

Root-caused and killed the intermittent e2e failure that showed up as 3–5 simultaneous test failures roughly 1 run in 4:
- REAL flake: nip46_bunker_connect_params_match_spec_against_strict_amber published its kind-0 through the DEFAULT relay set — the real internet (damus + the known-hanging nostr.band) — so "at least one relay must accept the signed kind-0" was a network lottery against the 6s send timeout. The test now pins settings to the in-process relay like the QR test always did. Suite has zero network dependency now.
- CASCADE amplifier: a panic while holding the test-only VAULT_ENV_LOCK poisoned the mutex, so every later test died on PoisonError. All four lock sites are now poison-tolerant (unwrap_or_else(into_inner)) — a real failure reports as ONE.

Verification (all green at a6a4e6f): 10/10 consecutive green e2e runs (was ~1 in 4 failing), runtime now uniform ~21.5s (was bimodal — long tail was network waiting). cargo test 216 unit + 5 e2e passed, cargo clippy --all-targets 0 warnings, cargo fmt --check clean, cargo build --release green.

a6a4e6f test(nip46): kill the e2e flake — local relay for strict kind-0, poison-tolerant vault lock

How to resume / reproduce

Restart Electron (new release binary). With the vault already unlocked/unencrypted, the backend logs [NIP46] restoring session: peer=... as npub1... then identity check on restored session: PASS and the profile goes Connected without showing Amber a new scan. CLI trace: ~/Tools/keynctr-debug/ logs.
Flake regression check: for i in 1..10; do cargo test --test nip46_e2e; done — all runs must pass in ~21–22s.
Then do the still-pending live proof: Publish name / publish a note and approve in Amber within 2 minutes (120s leash from f53bc56).

Outstanding / next steps

Live sign/publish through real Amber (covers the 120s leash and the restored session in one shot).
Prune the 11 stale profileless nip46_connections rows (cosmetic; restore already skips them).

Checkpoint — NIP-46 session restore on startup (2026-09-24)

Where things are

Branch master @ 0982dad; see git for hashes. Details below are as written when 0982dad was HEAD.

What was completed this session

Session restore without a fresh scan (0982dad): the WIP from the Sep-23 session (item 2 of the previous next-steps) is finished and committed. Amber remembers our client pubkey as the identity of an approved connection for its whole life, so the client keypair minted at pairing is now persisted in the vault (Vault::connection_client_keys — encrypted under the vault key exactly like connection secrets, keyed by the same VaultRef, and re-keyed to the identity ref when the handshake resolves it).
Re-dial path: reactivate_saved_sessions() picks the active profile's live connection (or any other live one), rebuilds the exact wire identity, re-derives the NIP-44 conversation key, and re-sends connect — no QR/bunker scan. It is called at serve() for unencrypted vaults and after UnlockVault for encrypted ones; a restore failure can never block the GUI.
Cross-account guard: restored sessions pin expected_identity before dialing; adopt_identity refuses (never adopts) a signer that answers as a different account — different Amber account, mistyped bunker, or relay spoof all fail closed.
Legacy connection rows without a stored client key are skipped (they need one fresh scan, after which they become restorable too).

Verification (all green at 0982dad): cargo test 216 unit + 5 e2e passed / 0 failed — incl. the new nip46_session_restore_redials_and_refuses_wrong_identity e2e (fresh pairing → simulated restart → re-dial connects → a fake Amber answering as a different key is refused) and 3 new vault unit tests (plaintext roundtrip, encrypted fail-closed, legacy-vault parsing). cargo clippy --all-targets 0 warnings, cargo fmt --check clean, cargo build --release green.

Release binary: rebuilt at f53bc56. No frontend changes — no renderer rebuild needed. Restart Electron before retesting.

What was completed this session

Confirmed live pairing WORKS: today's trace log shows two full successes against real Amber (identity adopted, CONNECTED at 15:17 and 15:37). The "Dev" profile row exists in ~/.local/share/keynectr/profiles_vault.json in nip46_client mode — the original complaint (no profile row, no persisted connection) is resolved as of the c789cb4 relay-set fix.
Diagnosed + fixed the remaining sign failure (f53bc56): logs show sign_event timing out at 30s while Amber's valid signature for the last request arrived ~61s after publication ("stale/duplicate response: no waiter ... dropped"). Every sign waits on a human approving Amber's prompt, so it was using the wrong leash. sign_event now uses SIGN_TIMEOUT = 120s (same as the connect handshake); get_public_key keeps the 30s retry-cadence timeout unchanged.

Verification (all green at f53bc56): cargo test 213 unit + 4 e2e passed / 0 failed (incl. nip46_qr_pairing_handshake_and_sign, which signs through the changed path), cargo clippy --all-targets 0 warnings, cargo fmt --check clean, cargo build --release green. Frontend untouched.

f53bc56 fix(nip46): give sign_event the human-approval timeout leash

How to resume / reproduce

Restart Electron (new release binary), re-pair or restore, then Publish name / publish a note: approve in Amber within 2 minutes and the signature will be accepted even if the prompt took a while.
If a sign still fails, check ~/Tools/keynctr-debug/ logs — a "TIMED OUT after 120s" now means the phone truly never answered.

Outstanding / next steps

Live sign/publish through real Amber with the 120s leash (fix is log-evidence-based; needs one live publish to confirm).
NIP-46 session restore on startup (re-scan needed after restarts).

What was completed this session

Feed author resolution (a76d8df): the feed previously rendered bare npubs + initial avatars — it never looked up author metadata anywhere. After collecting notes, the backend now runs ONE batched kind-0 lookup for all distinct authors (8s cap, best-effort; failures keep the npub fallback) and attaches the newest author_name (display_name preferred) + author_picture per note. FeedScreen renders the name (full npub on hover) and the picture avatar. Unit test covers newest-wins, display_name preference, and blank→fallback; new FeedScreen test covers name+picture rendering.
Note: anyone WITHOUT published kind-0 (like the user's own new identity until "Publish name" runs) still shows as npub — correct fallback, not a bug.

Release binary: rebuilt at 6f4dbb2. Renderer rebuilt via npm run build. Restart Electron before retesting.

What was completed this session

Closed the P2 kind-0 gap (6f4dbb2): the "Publish name" IPC path now routes through the profile's Signing source (same pattern as note publishing). Embedded profiles sign locally as before; a paired profile's kind-0 (label/picture/nip05) is signed by the remote signer — Amber shows an approval prompt — so the name becomes visible in every Nostr client. Disconnected sessions fail closed, never with a local fallback. CLI keeps the local-only path (no signer instances there).
E2E proof: the strict-Amber test now also publishes kind-0 through App::signing_for + publish_metadata_signed and asserts relay acceptance — the exact GUI path, with identity validation. Along the way fixed the test's production wiring (handle registered on App, as ensure_nip46_signer does) after a None-handle failure poisoned the shared env lock and cascaded to all 4 e2e tests.
Rename modal copy now points remote profiles at "Publish name" (Amber approval) instead of claiming the signer app publishes it.

How to resume / reproduce

What was completed this session

Diagnosed the Home flicker (my a8d112b polling regression): every 5s poll delivered a fresh state object identity, so Home's publications loader (useProfilePublications, keyed on settings.relays identity) refired forever — "Loading publications…" cycling. Fixed in 3d1c306: refresh() keeps the previous state object when content-identical (JSON compare), so idle polls are re-render silent. Poll timer uses global setInterval (testable under fake timers).
Regression test + harness fidelity: new HomeScreen test proves feed_get fires once across 12s of polling (verified RED without the guard: 3 fetches). fakeBackend get_state now deep-copies like the real IPC boundary — the shared-reference version masked the bug.
Diagnosed the publish failure: backend restarted 14:57 for the rename build, which killed the in-memory NIP-46 session (client keys + subs are memory-only by design). Vault keeps the connection row, but there is NO session restore on startup — publishing fails closed with "external signer selected but not connected" while Amber still shows connected. Re-scanning the QR re-establishes it (proven path). Automatic restore (fresh connect against the stored row) is the follow-up, not this change.

What was completed this session

Explained the generic "Remote Signer" label: the paired identity (npub1f3tura…) has NO kind-0 metadata on damus/primal/nos.lol (direct REQ check — all EOSE), so the background enrichment correctly found nothing to upgrade the pairing label with.
Label-only rename for remote profiles (6ebc364): rename_profile used to resolve the local secret first, so renaming a paired profile errored. Secretless Nip46Client rows now rename vault-side with an empty publish report (kind-0 signing still awaits the P2 external-signer reroute). Rename modal reports "saved on this device" for the empty report instead of a misleading "published to 0 relays". New regression test rename_profile_updates_label_for_secretless_remote_profiles.

ROOT CAUSE OF THE WHOLE SAGA — Amber's OS notification gate: Amber's in-app log showed all four get_public_key RPCs arriving on all relays, each followed by notifications disabled. Amber's EventNotificationConsumer.consume returns early when Android notifications are blocked for the app — every signer request dies silently after connect. Fix was on the phone: Settings → Apps → Amber → Notifications → Allow. (Battery "unrestricted" was already set and was never the issue.)
First live end-to-end pairing: after enabling notifications, the next scan completed in ~1s — identity adopted: npub=npub1f3tura29nrmhpp5v88z45knjejzdcx7ulvcz2jswau4raa7v25nsh6ltfw — CONNECTED. Vault holds the secretless Nip46Client profile as active; connection re-keyed under the identity. Amber shows the app; desktop Signer screens show Connected.
UI staleness found by the success (a8d112b): Home/Profiles read the launch-time state snapshot and never refetch (IPC has no push channel), so they still showed first-run Welcome after the background pairing. AppProvider now polls getState() every 5s (cheap local read, errors swallowed — screens surface their own failures).

Release binary: rebuilt at e02417b — Electron spawns this one. IMPORTANT: the running Electron/backend (started 10:06) predates every fix — quit fully and relaunch before any live test.

What was completed this session

Stale-binary trap found: the user's live scans ran against a backend started 10:06, before the 13:01 rebuild. Documented the full-quit + relaunch procedure (pkill, port-5173 conflict fix).
Live scan on the NEW binary (8f055f7) analyzed end to end: the [NIP46] trace is perfect through secret validation, but get_public_key (accepted by both relays, 4 attempts) gets zero responses and the demux subscription logs zero inbound — nothing is dropped, nothing arrives.
Fetched our own request event off relay.primal.net: author, p-tag, kind all textbook-correct. Unauthenticated REQ works on all four relays (no NIP-42 gate). Ephemeral retention is short (<~20 min), so both sides must be live-subscribed — late joiners get nothing.
Read Amber's own signer source (BunkerRequestUtils.kt, master): fresh localKey per approval, URI relays honored for nostrconnect://, listen-REQ-before-response, auto-approve get_public_key. Our wire behavior matches it — with current Amber the halves should meet.
Amber 6.6.5 (current) forensics: app entry correct (primal+nos.lol), activity log shows ONLY the Connect ack — Amber never receives our RPC. Battery already unrestricted.
Relay experiment (e02417b): Amber's issue history documents NIP-46 working over relay.damus.io; same-day write-canary from this network shows damus connected + accepting ephemeral 24133. Pairing set is now damus → primal → nos.lol (damus first).

Verification (all green at e02417b): cargo test 211 unit + 4 e2e passed / 0 failed, cargo clippy --all-targets 0 warnings, cargo fmt --check clean, cargo build --release green. Frontend untouched (suite last green at 8f055f7: 119 tests, typecheck, lint, format, electron:build, build).

e02417b fix(pairing): offer relay.damus.io first

How to resume / reproduce

Quit Electron fully first (pkill -f "electron ." → pgrep shows nothing), relaunch vite + Electron (release binary is current at e02417b), verify backend start time is NOW, then Signer Mode → Show QR (QR now lists damus/primal/nos.lol) → scan in Amber → approve with Amber foregrounded. Expect [NIP46] ... UI connection state updated: Connected.
If Amber still shows only the Connect ack, its phone-side relay path is the remaining suspect — report which relays Amber's entry lists and any new activity lines.

Outstanding / next steps

Live re-scan against e02417b (decisive; needs app restart first).
If damus doesn't help, consider pruning to fewer relays (force both ends onto one) or capturing Amber's in-app relay/connection log.
publish_profile_metadata kind-0 via Signing (P2), KDF upgrade (Step 5), rename pass (Step 7) — unchanged.

Checkpoint — NIP-46 handshake debugged: connect-params spec fix + full [NIP46] trace + visible errors (2026-09-23)

Where things are

Project: /home/avi/Projects/Keynctr
Branch: master @ 8f055f7 ("fix(nip46): spec-correct connect params, full-handshake [NIP46] trace, visible handshake errors"). Previous: 2bc6321 (identity-RPC retry), 9cfc1cf (relay-accept trace).

Release binary: rebuilt at 8f055f7 — Electron spawns this one.

What was completed this session

Spec-verified the whole signer flow against NIP-46 (20-point checklist in the session brief). URI generation, keypair handling, subscribe-before- publish, relay URL encoding, kind-24133 listen, NIP-44 decrypt, secret validation, identity-via-get_public_key, account-state update and UI polling were all traced file-by-file (nip46_client.rs, ipc.rs, SignerModeScreen.tsx, relays.rs, nip46_e2e.rs).
Found + fixed the definitive paste-flow (bunker://) bug (8f055f7): run_handshake sent connect params as [client_pubkey, secret], but NIP-46 (and rust-nostr's own NostrConnectRequest::Connect codec) require [<remote-signer-pubkey>, <optional_secret>]. Strict signers answer a malformed connect with silence, stalling the handshake with zero feedback. New pure helper connect_params(peer, secret) + 2 unit tests (one round-trips through the library codec).
Client keypair is now always ephemeral in connect() (was: reused the vault's local secret key when unlocked). Per NIP-46 the client keypair is disposable and must never be confused with the user's identity or a vault key. QR flow already did this; both flows now agree.
Full [NIP46] diagnostic trace across both flows (console stderr, in addition to the existing pairing-trace.log forensics): keypair gen, client pubkey, secret presence (NEVER values), relay connecting/connected, subscription created/registered (filter + id), URI generated, every inbound 24133 (author, tags, decrypt OK/real-error, method, secret PASS/FAIL, remote pubkey), every RPC publish/timeout/response-routing decision (including stale/duplicate ids), relay-health pre-check before each get_public_key retry (fails fast with a useful error when no relay is connected), user pubkey, account-state update, UI-state update.
Failures are visible now, not silent: fail() keeps the FIRST (specific) error instead of letting the demux exit overwrite it with generic "Connect handshake failed"; SignerModeScreen renders status.error as an alert in both the pairing and the idle/paste branches and shows a "Connection request sent — approve it in Amber" hint while a paste-URI connect is in flight. No fake Connected state anywhere: Connected still requires get_public_key to resolve the identity.
Tests: new strict-Amber e2e (nip46_bunker_connect_params_match_spec_against_strict_amber) — fake signer rejects connect unless params[0] is its own pubkey, then serves identity + sign like Amber; asserts the REAL user pubkey lands in the vault as a secretless row AND becomes the active profile. Verified RED on the old param order, GREEN on the fix. New SignerModeScreen.test.tsx (3 tests: QR waiting hint, connecting hint, failed-handshake error visible) + nip46_* dispatch in fakeBackend.ts. Also widened the e2e VAULT_ENV_LOCK to whole-test bodies (data_dir() re-reads process-global XDG_DATA_HOME on every save — one cross-write flake seen under full-suite parallelism) with targeted await_holding_lock allows.

Verification (all green at 8f055f7): cargo test 211 unit + 4 e2e passed / 0 failed, cargo clippy --all-targets 0 warnings, cargo fmt --check clean, cargo build --release green; frontend npm test 119 passed (17 files), typecheck, lint, format:check, electron:build, build clean.

8f055f7 fix(nip46): spec-correct connect params, full-handshake [NIP46] trace, visible handshake errors

How to resume / reproduce

Dev loop: cd frontend && npx vite --port 5173 then NOSTR_GUI_DEV_URL=http://localhost:5173 KEYNCTR_ENABLE_GPU=1 npx electron . (release binary already rebuilt at 8f055f7).
Live Amber re-scan (still the decisive test): Signer Mode → Show QR → scan in Amber → approve, keep Amber open in the foreground. Watch terminal/backend console for the [NIP46] lines in order (see "Expected logs" in the session report) and ~/Tools/keynctr-debug/pairing-trace.log.
E2E: cargo test --test nip46_e2e (4 tests, no network).
Frontend: cd frontend && npm test -- SignerModeScreen.

Outstanding / next steps

Live Amber re-scan against 8f055f7 — the QR flow's get_public_key silence (5 scans × 4 attempts, publishes accepted by primal+nos.lol, zero responses) is downstream of our publish: either Amber never receives our request (e.g. its subscription fails, NIP-42 AUTH on those relays from mobile, or the app was backgrounded) or it receives and never answers. The new demux logs distinguish these live: zero inbound lines during the retries ⇒ Amber-side; inbound-but-dropped lines ⇒ our filter/decrypt.
If the live trace shows zero inbound during retries, next step is a relay experiment (add a no-auth REQ relay to the pairing set) and/or confirming Amber stays foregrounded with network.
publish_profile_metadata (kind 0) still signs locally — reroute through Signing for external profiles (P2, pre-existing).
Step 5 (KDF upgrade), Step 7 (rename pass incl. homepage URL).

Dev loop: vite :5173 + NOSTR_GUI_DEV_URL=http://localhost:5173 KEYNCTR_ENABLE_GPU=1 KEYNCTR_FORCE_WAYLAND=1 KEYNCTR_NO_RELAUNCH=1 npx electron . (the FORCE_WAYLAND/NO_RELAUNCH pair keeps the crash-fallback ladder from drifting the window onto XWayland, where it fails to map on this Hyprland session).
What was completed this session:
1. First genuine live pairing captured (Sep 23 08:31 CDT): pairing started → inbound 24133 → connect accepted with secret echo → paired: connection stored — the c789cb4 relay fix is proven end to end. The session then died at identity adoption: get_public_key timed out.
2. Root cause 2e98e69: both connect flows spawned the handshake task BEFORE run_demux registered the kind-24133 author subscription, so the relay delivered Amber's fast identity reply into a gap with no active subscription and it was dropped; 30s later the RPC timed out, leaving the vault with a stored connection (profile_npub: None) but no profile — UI said "connected" while Home still showed first-run. Fix: new subscribe_to_signer opens the notification stream + subscription before any publish; run_sign_task and run_paired both subscribe first and pass the stream to run_demux. futures-util promoted to runtime dep.
3. Onboarding 13a66f2: first-run Home now offers three paths — Create a new profile / I already have an account (ImportProfileModal) / Sign in with a signer (navigates to Signer Mode). Copy states per-mode key truth (local vault vs remote signer key never on this device).

Resume / reproduce: dev-loop command above; scan the pairing QR with Amber from Signer Mode. Expected trace in /home/avi/Tools/keynctr-debug/ pairing-trace.log: pairing started → inbound 24133 → connect response accepted → paired: connection stored → identity adopted … CONNECTED, and a profile row appearing in ~/.local/share/keynectr/profiles_vault.json.
Outstanding / next steps:
- Live re-scan against 2e98e69 — the only missing proof; the stale half-paired connection row (Remote Signer, signer_pubkey 9597b46d…) is replaced by the new pairing.
- Consider pruning stale Remote Signer connection rows on failed adoption so the vault never keeps a profileless connection.

What was completed since the last checkpoint

First real live pairing attempt was captured — and diagnosed (c789cb4): the trace log now shows a genuine live session for the first time: pairing started at 18:01:29 CDT (ephemeral 7c695714…, relays damus/nostr.band/primal/purplepag) followed by session failed: Pairing timed out at 18:06:39 — the 5-min window ran with ZERO inbound 24133 events (capture file untouched since Sep 18). Post-hoc relay sweep (read-only REQ, results in /tmp/probe-results.json + /tmp/window-24133.json) found no kind-24133 event tagged to the ephemeral key on any of the four relays, and no kind-24133 at all in the whole 18:01–18:06 window. So Amber connected to a relay and published, but the event was discarded before storage.
Smoking gun via anonymous canary (throwaway random keys, zero user data; ~/Tools/keynctr-debug/canary-24133.py, results /tmp/canary-results.json): writing a kind-24133 event to each pairing relay → purplepag.es: OK false "blocked: kind 24133 is not allowed" — it silently drops signer connect traffic; relay.nostr.band: WebSocket handshake hangs (also pay-to-read); relay.damus.io + relay.primal.net + nos.lol: accepted + readable; relay.snort.social: accepted live ("ephemeral: will not be stored"), fine for pairing push. If Amber picked purplepag.es (it is in the URI), it would say "connected" while its connect event was rejected — exactly the observed symptom, and consistent with the earlier parse-failure theories being dead ends (the payload never arrived).
Fix (c789cb4): pairing_relays() is now damus.io, primal.net, nos.lol, relay.snort.social — both blockers removed, both replacements canary-verified for ephemeral 24133. Regression test pairing_relays_exclude_24133_blockers pins the blockers out.
Debug-dir hygiene: inspect.py removed (it shadowed the stdlib inspect module for any script run from that directory and leaked stale forensics output into terminal sessions); moved to inspect-capture.txt. Canary + probe scripts kept under ~/Tools/keynctr-debug/ (untracked tools dir).

Outstanding / next steps

Live Amber re-scan against c789cb4 — the relay-set fix is the best-evidenced change yet but only a live scan proves it.
Consider whether the user's two enabled relays (settings.json: damus.io + nostr.band) should swap nostr.band for nos.lol for ordinary traffic too (it hangs the handshake today; also pay-to-read).
If trace still shows timeout with the new set, next hypothesis is Amber not actually publishing (its "connected" = relay socket open); compare against Amber's own relay debug screen.

What was completed since the last checkpoint

Honest security copy (d4d87b8): the blanket "keys never leave the machine" claim in README.md (tagline), PRODUCT.md (purpose, positioning, principle 1), and DESIGN.md (North Star) was replaced with the per-mode truth: in embedded/bunker modes keys stay in the local encrypted vault and never reach the renderer; in external NIP-46 signer mode the key never arrives on this machine — a strictly stronger posture against desktop compromise. README security notes gained an explicit bullet saying external signer mode can be more secure. App UI (SignerModeScreen.tsx) already ranked external signer "Most Secure / Private key NEVER on this device" — no code or test changes were needed.

What was completed since the last checkpoint

Forensics de-noising (f6bf6a9): adopt_identity's identity adopted — CONNECTED trace line had no loopback gate, so every e2e run appended fake CONNECTED entries to ~/Tools/keynctr-debug/pairing-trace.log — three appeared during this cron's own cargo test runs and had to be manually distinguished from a real Amber scan. The line is now gated on live_relays() (same loopback test the event capture already uses; verified live: re-running cargo test --test nip46_e2e no longer touches the trace file's mtime). Also added a paired: connection stored; handing over to identity handshake trace line at the QR-pairing handover, so a stall between the connect echo and get_public_key now names itself in the trace.
Post-fix audit of the pairing flow (read-through, no code change): the QR path (pairing loop -> connect-response echo -> connection+secret persisted -> demux + adopt_identity -> profile row + vault save) is coherent end to end; send_rpc waiters register before publish; demux routes responses by id; failure paths call fail() which traces session failed: …. Nothing further to fix without live data.

Checkpoint — e2e vault-isolation bug found; Amber fix awaiting live test (2026-09-20)

Where things are (as of 2026-09-20)

Branch: master @ deeb4f9 + d52fa58. Feature HEAD: edd4e56.

What was completed since the last checkpoint

e2e vault-isolation bug found and fixed (d52fa58 + deeb4f9): both e2e tests seeded their isolation vault at $XDG_DATA_HOME/profiles_vault.json, but vault::data_dir() is $XDG_DATA_HOME/keynectr — so App::load() never saw the seed and try_migrate_legacy_vault() silently migrated the legacy repo vault (real profile, plaintext secret key) into the test process. Forensic proof: legacy-vault backups profiles_vault.json.backup-1789868634/670 timestamped Sep 19 20:43:54 + 20:44:30 — exactly the cargo-test runs around edd4e56. Consequence: the identity adopted trace lines from Sep 19 20:43 were e2e sessions, not a live Amber scan (session-level traces are not gated by live_capture). Fix: seed at tmp/keynectr/profiles_vault.json + assert-empty guard after every e2e App::load() so any future silent migration fails loudly. Verified after the fix: repo legacy vault byte-identical, backup count unchanged (77).
Pairing status unchanged: edd4e56 (accept the NIP-46 connect response shape) remains the root-cause fix; it has never yet faced a live scan.

What was completed since the last checkpoint

The likely root cause of the whole Amber pairing failure (edd4e56): for a client-initiated nostrconnect:// scan, NIP-46 specifies the signer sends a connect response — {"id":…,"result":"<secret>"} — not a connect request (spec: "the remote-signer … then sends connect response event to the client-pubkey"; result is "ack" OR the secret; "Client discovers remote-signer-pubkey from connect response author"). run_pairing_task only recognized an inbound {"method":"connect"} request. A bare {"result":…} parsed into RawRequest with an empty method (the lenient deserializer never fails, so the old "not a NIP-46 request" log couldn't fire) and was silently swallowed as "pre-handshake '' ignored" — Amber showed "connected", Keynctr sat in the pairing loop until timeout, no profile row, nothing persisted. That exactly matches the original symptom and the observed 89-byte plaintext ({"id":"…","result":"<16-byte-hex-secret>"} fits 65–96 B). The pairing loop now verifies the echoed secret (or "ack") directly and proceeds to identity adoption; a signer-sent error fails fast with the signer's message; a wrong secret is still ignored as spoofing; the legacy request shape keeps working. Trace lines added for each outcome.
e2e regression lock: run_fake_scanner takes a connect_shape param; new nip46_qr_pairing_connect_response_shape test simulates Amber's spec shape end-to-end. Confirmed RED on the pre-fix parser (pairing times out) and GREEN with the fix.

Checkpoint — durable pairing trace log + forensics-file hygiene (2026-09-18)

Where things are

Project: /home/avi/Projects/Keynctr
Branch: master @ 21c522b ("chore(pairing): durable trace log + keep e2e loopback traffic out of forensics files"). Previous feature HEADs: 188b2eb, aedde8f, 759b5dd, 5aa122d, f59c2b1.
Working tree: clean for tracked files. Untracked intentionally NOT committed: COSMIC_THEME.md, KeynectrAppIconPossibility02.jpeg, deferred/ (stays deferred).
Release binary rebuilt at 21c522b (2026-09-18 ~21:00) — Electron spawns this one. No live Amber scan has run against 188b2eb or 21c522b yet: the capture file shows no real scan since Sep 16 21:03.
Verification (all green at 21c522b): cargo fmt --check clean, cargo test 208 unit + 2 e2e passed / 0 failed, cargo clippy --all-targets 0 warnings, cargo build --release green. Frontend: npm test 116 passed, npm run typecheck / lint / format:check / build / electron:build all clean.

What was completed since the last checkpoint

Forensics contamination found and fixed: pairing-capture.jsonl had grown two new lines (Sep 18 20:08 + 20:42) that were NOT Amber — they were the e2e harness's fake-scanner events, appended because the capture path was hardcoded and the loopback e2e test pairs through the same run_pairing_task. Removed the two test events from the capture file (backup: pairing-capture.jsonl.bak-20260918); loopback pairings now skip the capture file and the pairing-session trace lines entirely (the session-level identity adopted / session failed lines are shared with the bunker flow and can still include a labelled e2e entry — distinguish by the loopback relay set in the preceding pairing started line, which real sessions never have).
Durable pairing trace (pairing-trace.log): every pairing decision point now appends a timestamped line to ~/Tools/keynctr-debug/pairing-trace.log — pairing started (ephemeral key
- relay set), inbound 24133, decrypt failure (real NIP-44 error), not-a-request (exact payload), pre-handshake method, connect answered, identity adopted (npub), session failed (reason). Backend stderr only reaches the Electron console and /tmp gets cleaned, so previously a failed live handshake left NO durable trace. Verified working: the e2e run after the change wrote identity adopted ... CONNECTED lines proving the trace path end-to-end.

21c522b chore(pairing): durable trace log + keep e2e loopback traffic out of forensics files

How to reproduce / exercise

Dev loop (unchanged): npx vite --port 5173 in frontend/ FIRST, then NOSTR_GUI_DEV_URL=http://localhost:5173 KEYNCTR_ENABLE_GPU=1 npx electron ..
GUI: Signer mode -> "Show QR" -> scan in Amber -> approve. After the scan (success OR failure), read ~/Tools/keynctr-debug/pairing-trace.log — the last lines name exactly where the handshake stopped. Raw frames still append to pairing-capture.jsonl (live pairings only now).

Outstanding / next steps

Live Amber re-scan still required — nothing has exercised the 188b2eb lenient parser against real Amber traffic yet. The trace log will show, without any terminal capture, whether the connect arrives, decrypts, parses, and how far the handshake gets.
If trace shows pre-handshake 'get_public_key' ignored, relax the connect-only gate (the log line names it outright).
publish_profile_metadata (kind 0) still signs locally — reroute through Signing for external profiles (P2).

Checkpoint — Amber pairing: lenient NIP-46 payload parse + real decrypt-error logging (2026-09-16)

Where things are

Project: /home/avi/Projects/Keynctr
Branch: master @ 188b2eb ("fix(pairing): never reject a decrypted NIP-46 payload on shape"). Previous feature HEADs: aedde8f, 759b5dd, 5aa122d, f59c2b1.
Working tree: clean for tracked files. Untracked intentionally NOT committed: COSMIC_THEME.md, KeynectrAppIconPossibility02.jpeg, deferred/ (stays deferred).
Release binary rebuilt at 188b2eb (2026-09-16 ~21:06) — the binary the Sep 15/16 Amber scans ran against was the Sep 12 build; the id-coercion + payload-dump diagnostics are live NOW.
Verification (all green at 188b2eb): cargo test 208 unit + 2 e2e passed / 0 failed, cargo clippy --all-targets 0 warnings, cargo fmt --check clean, cargo build --release green. Frontend: npm test 116 passed (16 files), npm run typecheck clean, npm run lint clean, npm run format:check clean, npm run electron:build and npm run build green.

What was completed since the last checkpoint

Universal-lenient RawRequest parse (188b2eb): the derived Deserialize (even after aedde8f's params coercion) still rejected real signer payloads. Replaced with a hand-written coercion deserializer: any valid JSON deserializes — numeric/missing ids become text, object-shaped params become a single param, a double-encoded JSON-string request is unwrapped. A parse failure is now only possible for non-JSON plaintext, which the log dumps verbatim. Regression tests for all five shapes.
Real decrypt-error logging (188b2eb): pairing decrypt failures now log the actual NIP-44 error (invalid HMAC vs invalid padding vs wrong conversation key) instead of a generic "wrong conversation key", and the not-a-request log prints the exact decrypted payload.
Offline forensics (no commit): all four captured pairing frames in ~/Tools/keynctr-debug/pairing-capture.jsonl (latest: Sep 16 20:11) are 163-byte NIP-44 v2 payloads = 1 ver + 32 nonce + 98 buffer + 32 MAC. 98 is a VALID final-spec padding bucket (plaintext 65–96 bytes; the observed 89 fits). So the frames are spec-conformant, decryption succeeds, and the failure was purely the JSON-shape parse — confirming the fix targets the right layer. Note /tmp/keynctr-el*.log no longer exists (tmp-cleaner); backend stderr now only reaches the Electron console — the next failed scan's payload dump needs npx electron . launched from a terminal or with stderr redirected.

How to reproduce / exercise

Dev loop (unchanged): npx vite --port 5173 in frontend/ FIRST, then NOSTR_GUI_DEV_URL=http://localhost:5173 KEYNCTR_ENABLE_GPU=1 npx electron .. To capture pairing diagnostics: run electron with stderr kept, e.g. ... npx electron . 2>&1 | tee ~/Tools/keynctr-debug/el.log.

GUI: Signer mode -> "Show QR" -> scan in Amber -> approve. Raw pairing events keep appending to ~/Tools/keynctr-debug/pairing-capture.jsonl.

Outstanding / next steps

Live Amber re-scan required (cannot be done from an unattended run): if pairing still fails, the backend log now contains the exact decrypted 89-byte payload and/or the exact NIP-44 error — that text names the last possible cause.
If the payload turns out to be valid JSON but not method:"connect" (e.g. Amber's deferred-approval get_public_key first), the log will show it and the handshake gate can be relaxed accordingly.
publish_profile_metadata (kind 0) still signs locally — reroute through Signing for external profiles (P2).

What was completed since the last checkpoint (7 feature commits + hygiene)

QR pairing (38499d4): Keynctr is the NIP-46 client, Amber scans. Signer screen mints a nostrconnect:// pairing token (ephemeral key + secret), renders it as a QR ("Show QR"), copy-link fallback, cancel. Backend listens for the signer's connect request, echoes the secret (anti-spoofing), persists the connection, adopts identity via get_public_key. e2e covers scan -> secret echo -> identity -> sign -> vault persistence with a fake QR scanner.
Electron allowlist (c5004eb): nip46_pair_start added to the main-process renderer allowlist (was rejected with "not permitted").
Lazy signer handle (dc58f38): all nip46_* IPC handlers ensure the client signer handle exists (fresh backend no longer answers "not initialized" until the mode is re-saved).
Pairing diagnostics (9cfab4b): pairing start + session failures logged to stderr (captured by Electron).
Real identity adoption (3d5302f): paired profiles get the signer's kind-0 display name/picture/nip05 (best-effort, 3s-capped) instead of a generic pairing label.
Instant Connected (286bbca): session flips to Connected as soon as identity is verified/persisted; metadata lands in a background task that never overrides a user-chosen label (fixes "Amber said yes but nothing changed").
Always-allow grants (81b082f): standing per-(peer pubkey, method) permission for external signer requests. Approvals gained an "Always allow" option; grants listed with Revoke on the Signer screen; persist in the encrypted vault (src/vault.rs grant storage).
Hygiene (22d7c01): gitignore editor artifacts, prettier-fix SignerScreen.tsx (format:check had been failing since 81b082f), delete dead nip46_external.rs stub.

Checkpoint — NIP-46 e2e test + bunker:// frontend support (2026-09-11)

Where things are

Project: /home/avi/Projects/Keynctr
Branch: master @ 85756df ("feat(signer): accept bunker:// URIs, async signer permissions, NIP-46 e2e test"). Previous: c096705, f917e5e.
Working tree: clean for tracked files. Untracked junk intentionally NOT committed: .opencode/, .impeccable/, .directory, COSMIC_THEME.md, KeynectrAppIconPossibility02.jpeg, deferred/, and the dead stub src/signer/nip46_external.rs.
Verification (all green this session): cargo test 200 + 1 e2e passed / 0 failed, cargo clippy --all-targets 0 warnings, cargo fmt --check clean, cargo build --release green. Frontend: npm test 116 passed (16 files), npm run typecheck clean, npm run lint clean, npm run format:check clean (Prettier applied to the 4 previously-warning files), npm run electron:build and npm run build green.

What was completed (this session)

tests/nip46_e2e.rs (new, 450 lines): full in-process NIP-46 client test — minimal local relay + fake Amber speaking the bunker flow, NIP-44 round-trip, connect handshake, identity asserted to come from get_public_key (URI key must never become identity), sign_event result verified against the signer pubkey, vault persistence asserting profile.secret_key stays empty for remote profiles.
Frontend bunker:// support landed: SignerManager.parseExternalSignerURI accepts bunker:// (pubkey = authority before @) as well as nostrconnect://; SignerModeScreen validates both, placeholder/hint explain Amber vs Nostr Connect sources.
Signer trait permission surface made async (permissions, can_*, is_connection_valid now async, blocking_lock -> lock().await).
Dev-loop gremlins fixed along the way: zombie vite on :5173 killed, stray Electron (launched against dead vite, SIGTRAP core dump) cleaned up, app relaunched and confirmed on screen.

Checkpoint — Vault-load rewrite fix + Amber handshake lands (2026-09-11)

Where things are

Project: /home/avi/Projects/Keynctr
Branch: master @ c096705 ("fix(vault): stop rewriting the vault on every load; clippy cleanup"). Previous: f917e5e (Amber-compatible handshake).
Working tree: clean for tracked files (untracked leftovers unchanged — see older "Still untracked" sections).
Verification: cargo test 200 passed / 0 failed, cargo clippy --all-targets 0 warnings, cargo fmt --check clean, cargo build --release green. (Frontend untouched this session; vite dev server still running on :5173.)

What was completed (this session)

Carried-forward open question — CLOSED, landed as c096705. migrate_vault_signer_modes used to return changed = true unconditionally, so App::load re-encrypted and re-saved the vault on every single start. Now a change is reported only when vault.version actually moves: per-profile signer_mode normalisation was always a no-op (the serde default fills missing fields at parse time and the current version serialises it explicitly). The idempotency test was tightened to assert changed == false for a current-version vault. Also dropped a clone-on-Copy in nip46_client.rs::get_public_key (clippy warning from f917e5e).

f917e5e (committed earlier today, before this session): Amber-compatible NIP-46 handshake — bunker:// URIs accepted, URI authority key no longer treated as identity (Amber mints a per-connection comms key; real identity learned via get_public_key after the connect ack), 120 s human-approval window with the session held in Connecting (fail closed), absent perms= delegates enforcement to the signer, send_rpc honours its timeout. On-device Amber round-trip has not been re-verified since this commit — that is the next task.

Checkpoint — External NIP-46 signing works end-to-end (2026-09-10)

Where things are

Project: /home/avi/Projects/Keynctr
Branch: master @ 1af79d8 ("feat(signer): end-to-end external NIP-46 signing in publish and upload auth").
Working tree: clean for tracked files (untracked leftovers unchanged — see older "Still untracked" sections).
Verification: cargo test 200 passed / 0 failed, cargo clippy --all-targets clean, cargo fmt --check clean, cargo build --release green.

What was completed (this session)

Step 3 sub-step 2 (IPC reroute) — DONE, landed as 1af79d8. Publishing from an external (NIP-46) profile now signs remotely instead of returning "External signer not yet supported":

src/signer/nip46_client.rs — the outbound/client half of NIP-46: send_remote_request encrypts a request (NIP-44) and publishes it to the signer's relay; incoming payloads shaped like responses (result/error) are demultiplexed to the waiting caller (a response with no registered id is ignored); 30 s REQUEST_TIMEOUT; pending waiters are woken with errors on disconnect/failure so callers never hang the full timeout. Signer::sign_event is real now: permission check → remote sign_event → verify the returned event (a) is signed by the connected remote identity, (b) matches the exact unsigned event requested, (c) has a valid signature — then return it. No local-key fallback anywhere. audit_permission_denied uses try_lock (audit is best-effort; blocking here would deadlock the very request being denied while the IPC dispatcher holds the App lock).
src/app.rs — App::signing_for(npub) / App::signing_active(): the single place that maps a profile's SignerMode to a Signing source. Embedded → Signing::Local with the vault-resolved key; Nip46Client → Signing::External wrapping the live signer only when present and connected, else ExternalSignerNotConnected (fail closed, never a silent local fallback); Nip46Bunker (not wired) also fails closed.
src/publish.rs — publish_with_keys builds the unsigned event from the Signing's own pubkey (external identities validate there before any relay work) and signs via Signing::sign; new publish_signed entry point for IPC. The CLI's publish_active/publish_as keep the local vault path.
src/ipc.rs — PublishNote and UploadAuth route through app.signing_active(); no handler branches on signer mode anymore. Nip46Connect/Nip46Disconnect now clone the signer handle and drop the App guard before awaiting connect()/disconnect() (they re-lock the App internally — a latent deadlock, fixed).
src/relays.rs — keyless relay pool: open_pool_inner(Option<Keys>, …) so external signing can publish/relay without local keys (no relay AUTH).
src/uploads.rs — nip98_authorization(url, method, &Signing) — NIP-98 upload auth events sign through the same Signing source, so uploads authenticate with the remote signer for external profiles.
src/profiles.rs — store_remote_profile(vault, npub, label): connecting a NIP-46 signer creates/refreshes a secretless Nip46Client profile row (empty secret_key, made active) so publish has a selection; refuses to silently convert an existing local profile into a remote one. connect() calls it and adopts the remote npub as the signer's active profile.

New tests (src/app.rs): embedded → Signing::Local; external profile with no live signer → ExternalSignerNotConnected (fail closed); no active profile → NoActiveProfile; store_remote_profile creates a secretless external profile and refuses to clobber a local one.

Security properties: remote-signed events are triple-verified (identity, content match, signature) before publish; external profiles never touch a local key; the connection secret stays vault-encrypted (Step 3 sub-step 1 unchanged).

Out of scope this session (deliberate)

publish_profile_metadata (kind 0) still signs locally from the vault — a synchronous key-based path; rerouting it is a separate follow-up.
Dead src/signer/nip46_external.rs stub cleanup (untracked leftover).
Step 4 (permissions UI), Step 5 (KDF upgrade), Step 7 (rename/hygiene).

Checkpoint — Undo-delete restores working profiles (2026-09-10)

Where things are

Project: /home/avi/Projects/Keynctr
Branch: master @ d101b8e ("fix(undo): restore full profile with secret key on undo-delete").
Working tree: clean for tracked files. Only untracked entries are the pre-existing hygiene leftovers plus two Rust scratch files (all intentionally untracked — see "Still untracked").

What was completed (this session)

Step 6 (undo history) — the hollow-undo bug is fixed, landed as d101b8e. Deleting a profile used to keep only a ProfileSummary on the undo stack, so undo re-created the profile with secret_key = "" — a dead shell that could never sign. The undo stack now keeps the full stored record:

src/profiles.rs — new DeletedProfile { summary, stored } struct; delete_profile_record() returns the real stored secret (plaintext or encrypted blob, exactly as on disk) plus the safe UI summary; delete_profile() stays as the summary-only wrapper for callers that keep no undo entry.
src/app.rs — App.undo_history is now Vec<DeletedProfile> (secret material never leaves the backend); undo_delete() restores the real StoredProfile, refuses to create a hollow profile (empty secret → entry handed back + error), and state_view() still exposes only summary items so the renderer never sees a secret. New regression test undo_delete_restores_working_profile_without_leaking_secret locks this in.
src/ipc.rs — DeleteProfile routes through delete_profile_record so the GUI undo entry carries the secret (previously it pushed a summary-only entry, so GUI undo was still hollow).
src/main.rs — CLI delete-profile/undo-delete use the same record path (delete_profile_direct → delete_profile_record, cli_undo_delete → app.undo_delete()); also fixes the old "label looked up after removal" bug by capturing the label before deletion, and drops the now-unused imports.
Compile fixes included: the inherited work-in-progress did not build (DeletedProfile vs ProfileSummary mismatch in ipc.rs, partial moves in undo_delete); both resolved, plus cargo fmt applied.

Security properties: secret material stays backend-only (AppStateView.undo_history is still Vec<ProfileSummary>); undo restores the exact stored blob (no re-derivation, no logging); empty-secret entries fail closed instead of writing hollow profiles.

Open question carried forward: migrate_vault_signer_modes reports a change on every load (always changed = true), so App::load re-saves each start.

Checkpoint — NIP-46 Connection Secrets in the Vault (2026-09-04)

Where things are

Project: /home/avi/Projects/Keynctr
Branch: master @ 510cb65 ("feat(signer): store NIP-46 connection secrets in the vault, keyed by VaultRef").
Working tree: clean for tracked files. No tracked file is modified or staged. The only untracked entries are the pre-existing hygiene leftovers and the source JPEG (all intentionally untracked — see "Still untracked"). Build artifacts (release/, dist/) are gitignored.

What was completed (this session)

Step 3 sub-step 1 (Vault integration) — landed as 510cb65. The NIP-46 nostrconnect secret is a credential, so it no longer lives inline on Nip46Connection (which can be serialized and shown to the UI). It is now stored in the vault's encrypted connection_secrets store, keyed by the opaque VaultRef (profile npub + remote signer pubkey), encrypted under the vault key, and resolved only at the vault boundary while the vault is unlocked (fail-closed when locked). This is where the vault_ref constraint becomes load-bearing.

src/vault.rs — new ConnectionSecret { ref_: VaultRef, secret } struct and a Vault.connection_secrets: Vec<ConnectionSecret> store (encrypted under the vault key when password-protected, plaintext when the vault has no password — exactly mirroring how profile secrets are handled). Three helpers:
- store_connection_secret(vault, key, ref_, secret) — upserts by VaultRef; encrypts when the vault is password-protected, else stores plaintext. A locked encrypted vault fails closed (vault_locked) rather than silently writing a plaintext secret that would not match once unlocked. Replacing an existing VaultRef never leaves a stale secret behind.
- resolve_connection_secret(vault, key, ref_) — decrypts (or returns plaintext) for a VaultRef; Ok(None) when no secret is stored, Err(vault_locked) when the vault is encrypted but locked. On success the plaintext is Zeroizing (shredded on scope exit).
- delete_connection_secret(vault, ref_) — removes an entry (on disconnect).
src/signer/types.rs — the inline secret: Option<String> field is removed from Nip46Connection. Legacy vaults that still carry an inline secret deserialize fine (serde ignores the absent field) and the dead secret is dropped on the next save.
src/signer/backend.rs — VaultRef::from_connection(&Nip46Connection) is the canonical way a SigningBackend::Remote (and the secret store) is keyed by a connection; profile_npub is now Option<String> (a connection may be created with no local profile active).
src/signer/nip46_client.rs — on connect, the parsed nostrconnect secret is written to the vault store (via VaultRef::from_connection) instead of being kept in memory (Nip46Inner.connect_secret removed). On disconnect the stored secret is dropped. In run_sign_task/send_connect, the connect secret is now resolved on-demand from the vault (the single source of truth) rather than read from an in-memory copy — a locked vault refuses the connect instead of sending it without the secret.
src/publish.rs — publish_with_keys now takes &Signing and signs through the Signing trait (routes to Keys::sign_event for Local, or the remote signer for External), instead of calling Keys::sign_event directly. publish_active / publish_as wrap their keys in Signing::Local. (External signing in the publish path is not wired end-to-end yet — it returns a clear "not yet supported" error — but the routing pattern is in place for the IPC reroute.)
src/signer/permissions.rs — test fixtures updated for the removed inline secret field.

Security properties: no secret material is logged; the connect secret is resolved fresh from the vault at send time (fail-closed on a locked vault); a serialized Nip46Connection or SigningBackend::Remote carries zero secret material; the decrypted plaintext is Zeroizing.

The previously-landed foundation (e6e4922 SigningBackend/SigningError/VaultRef, b2755d8 Signer trait returning SigningError) is unchanged by this commit — it is what this sub-step wires up.

The previously-uncommitted working tree (27 modified + 10 untracked files, ~1852/692) was triaged into three logical, independently-verifiable commits in a prior session, and the packaging fix landed in 114b343. Order is a → c → b → (packaging): ExportSecretKey (b) reads the per-profile signer_mode field and the external_signer_not_connected error that the signer-mode commit (c) introduces, so (c) had to land first. The only uncommitted tests were the export tests and the signer-mode/permission tests, so "(d) tests" is not a separate commit — each feature's tests travel with it.

Per-profile signer modes + persisted NIP-46 connections (c) — three coexisting signing modes (Embedded / Nip46Client / Nip46Bunker), a signer_mode field on every stored profile, a vault nip46_connections store (owner-scoped, with parsed permissions, expiry, revocation), the expanded Signer trait (identity validation, Signing enum, permission surface), the NIP-46 permission model, and the redesigned Signer Mode screen with a nostr-tools-based client.
Fail-closed key export (b) — export_secret_key always re-authenticates, requires a reason, refuses external-signer profiles, and writes the audit entry before returning the key (fail-closed on audit failure). Frontend ExportSecretKeyModal replaces the old reveal modal.
Hash-chained audit log (a) — SHA-256 hash-chained append-only log with atomic append and end-to-end verify_chain(); the sha2 dependency.
Packaging icon restored (this session, 114b343) — frontend/build/icon.png was deleted from the working tree, so electron-builder had no Linux icon and every AppImage/deb it emitted carried the generic Electron placeholder. The icon was regenerated from KeynectrAppIconPossibility02.jpeg (not resized): the white (254) JPEG background was cut to transparent (alpha derived from luma), the art was flattened to a square canvas with symmetric padding, ink kept pure black (RGB 0,0,0), and exported as 512x512 RGBA. The single declared config path (linux.icon: build/icon.png) was kept single — no build/linux/ fan-out — because the 512 master satisfies both targets: AppImage downscales to 256 internally (≥256 required) and the deb installs usr/share/icons/hicolor/512x512/apps/keynectr.png, matching the generated .desktop Icon=keynectr.

Security properties confirmed

No secret material is logged or returned except the single, authenticated, audited export. The export reason is logged by design; passwords and nsecs are not.
Export is fail-closed: a failed audit write prevents the key from being returned (log.record(...)? — the earlier let _ = that let a key out on audit failure is gone).
External (Nip46Client) profiles cannot export a secret key — the key is not local.
Profile identity is resolved server-side (profiles::find_stored_profile), not trusted from the client.
NIP-46 permissions are deny-by-default and cannot be broadened on reconnect.
Audit writes are serialized (single mutex across the read-compute-write-update cycle) and the chain is tamper-evident from a genesis hash.
Renderer never receives an nsec outside the intentional one-time export.

`510cb65`	feat(signer): store NIP-46 connection secrets in the vault, keyed by VaultRef

(The parent chain — b2755d8 Signer trait returns SigningError, a2307ac checkpoint, e6e4922 SigningBackend+SigningError+VaultRef, ee88171 checkpoint, 114b343 packaging icon, d92371f checkpoint, 6eff510 export, 2c61830 signer modes, caed722 audit log — is unchanged.)

Verification (run this session)

Full suite per AGENTS.md, run on top of 510cb65:

Rust: cargo test → 196 passed, 0 failed (no new/removed tests — this sub-step refactors existing code paths; the existing signer::backend, vault, and nip46_client tests cover the change); cargo clippy --all-targets → clean (exit 0); cargo fmt --check → clean (exit 0); cargo build --release → Finished, exit 0.
Frontend: npm test → passed; npm run typecheck → exit 0; npm run lint → exit 0; npm run electron:build → exit 0; npm run build → exit 0. npm run format:check → exit 1 on the 5 pre-existing files (ExportSecretKeyModal.tsx, SignerModeScreen.tsx, AppProvider.tsx, ExportSecretKey.test.tsx, fakeBackend.ts) — these are the documented Step-7 Prettier hygiene failures, not introduced by this Rust-only change (none of the 6 modified files are frontend). Left untouched here.

How to reproduce / exercise

Backend: cargo run --release -- serve (JSON-lines IPC on stdio) or the CLI in src/main.rs.
GUI: from frontend/, npm run electron:build && electron . (prod) or npm run start:dev with NOSTR_GUI_DEV_URL.
Packaging: from frontend/, npm run dist (unpacked dir) or npx electron-builder --linux AppImage deb (declared targets) → artifacts in release/.
Exercise export: Profiles → a profile → Export secret key → enter the vault password and a reason. An external (NIP-46 client) profile shows it cannot export.
Exercise modes: Signer Mode screen → pick Embedded / NIP-46 client; connect a nostrconnect:// URI with a perms= parameter to grant scoped permissions.

Still untracked (do NOT lose; do NOT commit the hygiene junk)

Source JPEG KeynectrAppIconPossibility02.jpeg — intentionally untracked (the icon is now derived from it; the JPEG itself is not a build input and stays out of git, per instruction).
Pre-existing untracked hygiene leftovers (out of scope, address in the Step-7 hygiene pass): COSMIC_THEME.md, .opencode/, .impeccable/, .directory.
frontend/build/icon.png is no longer a leftover — it was regenerated and committed in 114b343 this session. The prior "deleted icon" item is closed.
Build artifacts release/ and dist/ are gitignored and not committed.
profiles_vault.json* and target/ remain correctly untracked and uncommitted (vault is gitignored).

On the record (not fixed, per instruction)

package.json → homepage still reads https://github.com/avi/Keynctr. This is the Step-7 rename/hygiene item and was left untouched in this session; noted here so it is on the record rather than silently fixed.

Deferred / next steps (unchanged, plus new)

Step 2 (packaging): DONE. Icon restored, npm run dist + declared targets green, icon proven inside both artifacts, committed as 114b343.
Step 3 (signer abstraction) — foundation landed as e6e4922 (SigningBackend + VaultRef + SigningError in src/signer/backend.rs, 10 tests, full Rust suite green); b2755d8 made the Signer trait return SigningError. Sub-step 1 (Vault integration) — DONE, landed as 510cb65: the encrypted connection_secrets store keyed by VaultRef, on-demand secret resolution at the vault boundary (fail-closed when locked), and the inline Nip46Connection.secret field removed. The Remote { vault_ref } variant holds only a VaultRef — the NIP-46 connection secret is never inlined. Remaining sub-step: 2. IPC reroute — drive src/ipc.rs handlers through SigningBackend (selected per-profile) so no inline signer_mode/handle-presence branching remains; convert handler results to AppError via From<SigningError>. Also wire end-to-end external (remote) signing in the publish path (publish_with_keys currently returns "not yet supported" for Signing::External). Prior state that motivated the API: src/signer/mod.rs already had a Signer trait and Signing enum (Local(Keys) / External{signer, profile_pubkey}); SignerMode (Embedded/Nip46Bunker/Nip46Client) lives on StoredProfile (per-profile) and is duplicated on App (app-level), and App holds three separate signer handles (embedded_signer, nip46_signer, nip46_bunker_signer). The IPC dispatcher (src/ipc.rs) branches on signer_mode/handle presence in ~12 sites.
External-signer permissions (Step 4): wire src/signer/permissions.rs into the approval modal so grants (kinds, relays, expiry, rate) are persisted AND enforced in the UI, not just parsed.
Deferred security (Step 5): KDF upgrade to m=64 MiB / t=3 with vault-header versioning
- backward-compatible migration; --allow-env-secret flag; remove or gate deprecated RevealSecretKey IPC behind the same fail-closed path.
Undo history (Step 6): resolve the ProfileSummary-loses-the-secret question.
Hygiene (Step 7): Keynctr rename pass (includes the homepage → correct repo fix noted above), delete legacy Python, migrate root profiles_vault.json* into ~/.local/share/keynectr, and a Prettier format pass to clear the 5 pre-existing format:check failures.
Open question carried forward: migrate_vault_signer_modes currently reports a change on every load (always changed = true), so App::load re-saves the vault each start. Harmless (idempotent) but wasteful; tighten to only report real changes.
