From 0207636a7a2a18ef7a6c375d0bc5b572e60a6150 Mon Sep 17 00:00:00 2001 From: Avi Date: Tue, 1 Sep 2026 10:41:28 -0500 Subject: [PATCH 01/48] feat: expose profile import over IPC Wire the existing profiles::import_profile through the JSON-lines IPC protocol so the GUI can add an existing account: ImportProfile request and handler in src/ipc.rs, import_profile added to the Electron method allowlist, api/AppProvider importProfile, and the Add existing account buttons in ProfilesScreen. Also add the active signing identity card on Home and fix the HomeScreen tests whose text queries now match the identity card as well as the profile row. --- frontend/electron/main.ts | 1 + frontend/package.json | 1 + frontend/src/lib/api.ts | 2 + frontend/src/lib/types.ts | 3 +- frontend/src/screens/HomeScreen.tsx | 25 ++++++++ frontend/src/screens/ImportProfileModal.tsx | 62 ++++++++++++++------ frontend/src/screens/ProfilesScreen.tsx | 19 ++++-- frontend/src/state/AppProvider.tsx | 12 ++++ frontend/src/styles.css | 64 +++++++++++++++++++++ frontend/src/test/HomeScreen.test.tsx | 14 ++++- src/ipc.rs | 18 ++++++ 11 files changed, 194 insertions(+), 27 deletions(-) diff --git a/frontend/electron/main.ts b/frontend/electron/main.ts index d973028..604c9a3 100644 --- a/frontend/electron/main.ts +++ b/frontend/electron/main.ts @@ -195,6 +195,7 @@ const RENDERER_METHODS: ReadonlySet = new Set([ 'init', 'get_state', 'create_profile', + 'import_profile', 'select_profile', 'publish_profile_metadata', 'set_profile_picture', diff --git a/frontend/package.json b/frontend/package.json index 8fa43e2..5886ed4 100644 --- a/frontend/package.json +++ b/frontend/package.json @@ -22,6 +22,7 @@ "format:check": "prettier --check .", "electron:build": "tsc -p tsconfig.electron.json", "start": "npm run electron:build && electron .", + "start:dev": "npm run electron:build && NOSTR_GUI_DEV_URL=${NOSTR_GUI_DEV_URL:-http://localhost:5173} electron .", "desktop:install": "bash scripts/install-desktop-entry.sh", "dist": "npm run build && npm run electron:build && electron-builder --linux dir" }, diff --git a/frontend/src/lib/api.ts b/frontend/src/lib/api.ts index 8f0f7d6..ff1c928 100644 --- a/frontend/src/lib/api.ts +++ b/frontend/src/lib/api.ts @@ -52,6 +52,8 @@ export const api = { getState: () => call('get_state'), createProfile: (label: string, settings?: Settings) => call<{ profile: ProfileSummary; state: AppState }>('create_profile', { label, settings }), + importProfile: (label: string, secret: string) => + call<{ profile: ProfileSummary; state: AppState }>('import_profile', { label, secret }), selectProfile: (npub: string) => call('select_profile', { npub }), publishProfileMetadata: (npub: string) => call('publish_profile_metadata', { npub }), diff --git a/frontend/src/lib/types.ts b/frontend/src/lib/types.ts index f64bd77..5030525 100644 --- a/frontend/src/lib/types.ts +++ b/frontend/src/lib/types.ts @@ -1,4 +1,5 @@ -export type Theme = 'light' | 'dark' | 'glass' | 'neon' | 'impeccable' | 'impeccable-dark' | 'cosmic'; +export type Theme = + 'light' | 'dark' | 'glass' | 'neon' | 'impeccable' | 'impeccable-dark' | 'cosmic'; /** Lifecycle of the NIP-46 remote signer. */ export type SignerPhase = 'stopped' | 'connecting' | 'connected'; diff --git a/frontend/src/screens/HomeScreen.tsx b/frontend/src/screens/HomeScreen.tsx index 0bf3db6..f391857 100644 --- a/frontend/src/screens/HomeScreen.tsx +++ b/frontend/src/screens/HomeScreen.tsx @@ -76,6 +76,31 @@ export function HomeScreen({ onNavigate, onCreateProfile }: HomeScreenProps) { + {active && ( +

The visible brand is `SOLARPUNK SUMMIT` with `KITCHEN 484`. -2. **Fixed broken profile delete/undo** (previous). `src/ipc.rs` missing `DeleteProfile`/`UndoDelete`; added handlers returning `state_view`; exposed `profiles::delete_profile` outside tests; `api.ts`/`AppProvider` now `call` via `applyState`; `fakeBackend` delete/undo. -2. **Themed auto-dismiss undo bar.** Replaced permanent white bar with `var(--primary-soft)` + `var(--primary)` link `Undo and restore profile`, 5s `useEffect` watching `lastDeleted`, shown in both empty/populated states. -3. **Impeccable themes (light + dark).** `src/settings.rs`: `Theme::Impeccable` + `ImpeccableDark` (serde `impeccable-dark`); `types.ts` union extended; `styles.css` added `:root[data-theme='impeccable']` (oklch 97% lacquer light, kinpaku gold `oklch(77% .13 82)`, Alumni Sans 300) and `impeccable-dark` (oklch 15% lacquer-deep, champagne text), editorial refinements (uppercase labels, 8/3px radii, nav left-border active, card offset bar); `SettingsScreen.tsx` adds both options with live `var(--*)` swatches. -4. **Unified ProfileEditModal.** `frontend/src/components/ProfileEditModal.tsx` — Paper Lift modal (`var(--surface)`/`var(--border)`/`16px`/`0 12px 40px`), 3 tabs (Name/Picture/NIP-05) sharing `renameProfile`/`setProfilePicture`/`setNip05`; `ProfilesScreen.tsx` wires `Edit profile` (secondary) alongside legacy ghosts; `DESIGN.md` + `PRODUCT.md` + `.impeccable/design.json` from `impeccable document` (Vault & Atelier, warm ivory/charcoal/coral, 9 primitives). -5. **Linux installers.** Electron Builder now produces both AppImage and Debian targets.

No behaviour change — both were dead code. -2. **Profile import is now usable from the GUI.** The `profiles::import_profile` - function (already in the Rust core from the account-import work) is now exposed - through the JSON-lines IPC protocol: new `ImportProfile` request and handler in - `src/ipc.rs`, `import_profile` added to the Electron method allowlist, - `api.importProfile` + `AppProvider.importProfile` in the frontend, and - "Add existing account" buttons on the Profiles screen (empty and populated - states). The existing `ImportProfileModal` (enter only the private key; the name - and kind-0 metadata are derived from the network) is now wired to it. -3. **Active signing identity card on Home.** The Home screen shows a card with the - active profile's avatar, name, shortened npub, and a "Switch profile" button. -4. **HomeScreen test fixes.** The identity card duplicates the active profile's name - and npub on the page, so the two affected tests now scope their queries to the - identity card (via the "Active signing identity" heading) and to the profile - list, instead of querying the whole screen. -5. **Prettier** applied to `ImportProfileModal.tsx`, `ProfilesScreen.tsx`, - `AppProvider.tsx` (and the test file), clearing the three existing - `format:check` warnings — `npm run format:check` is now fully clean. -6. **HomeScreen keyboard accessibility (this session).** Profile list rows - (`
    1. ` elements) are now keyboard-focusable and operable: - - Added `role="listbox"` on the `
        ` and `role="option"` + `aria-selected` - on each non-active `
      • `. - - Added `tabIndex={0}` so non-active rows receive keyboard focus. - - Added `onKeyDown` handler (Enter/Space to select) matching the existing - `onClick` behavior (skips if target is a button/a/input). - - Added descriptive `aria-label` including profile name and active state. - - Added `.home-profile-row:not(.is-active):focus-visible` CSS rule for the - standard 2px solid var(--focus) + 2px offset ring. - - Updated the test from `findByRole('list')` to `findByRole('listbox')`. -7. **HomeScreen design-system alignment (this session).** Polish pass addressing - critique findings: - - Removed the identity card's `linear-gradient` background — now flat - `var(--surface)` with `border-color: var(--success)` (flat-by-default rule). - - Fixed `.home-profile-row` border-radius from `8px` to `var(--radius-sm)` (9px). - - Replaced the publication empty-state sentence with a centered layout: icon + - muted text + secondary button, matching the product's empty-state language. - - Normalized `.home-identity-name` font-size from `18px` to `16px` (consistent - with `.profile-name`). - - Removed redundant `grid-template-columns: 1fr` from `.home-grid`. -8. **First-run guide redesign (this session).** Replaced plain `
          ` with visual - step indicators: each step has a `primary-soft` icon circle (users, copy, edit) - alongside a title + description. Clear spatial hierarchy, consistent 14px text. -9. **Identity card background restored.** After removing the gradient, the card - lost its green tint. Restored as flat `var(--success-soft)` background — keeps - the security-state signal without breaking flat-by-default. -10. **Re-critique score: 27/40 → 30/40 (Good).** All P1s resolved, all P2s - resolved. Remaining items are P3 (keyboard shortcuts, search/filter, minor - copy inconsistencies). -11. **Compose label alignment (this session).** Changed HomeScreen header button - from "Compose note" to "Compose" to match the sidebar nav label. Updated - tests to use exact name matching and scoped queries. -12. **Identity card simplified (this session).** Removed "Active signing identity" - kicker text. Card now uses flat `var(--surface)` background with - `var(--success)` border — matches the active profile card treatment. - Removed dead `.home-identity-kicker` CSS. -13. **Polish cleanup (this session).** Removed dead `.active-profile-row` CSS - class. Replaced hardcoded `rgba` fallbacks in `.home-profile-row.is-active` - with design tokens (`var(--surface-2)`, `var(--border)`). Removed duplicate - edit icon from publication empty state. -14. **Identity card removed (this session).** The entire identity card was removed - from HomeScreen — the subtitle ("Publishing as …") and the active profile row - in the list already convey the same information. Removed ~75 lines of dead CSS - (`.home-identity-card`, `.home-identity-content`, `.home-identity-copy`, - `.home-identity-name`, responsive rules). Updated the test to verify the - profile name and npub in the profile list instead of the removed card. -15. **HomeScreen polish pass (this session).** Aligned spacing to the 8/12/16/20/32 - design scale: profile list gap 10→12px, add-profile margin 14→16px, publish - empty-state padding 8→12px, page-subtitle margin 4→6px. Added - `.home-profile-row:not(.is-active):hover` with `var(--surface-hover)` for - visible hover feedback on selectable rows. -16. **"View in Feed" button after publish (this session).** After a successful or - partial publish, both the Compose screen's Result card and the Home screen's - "Most recent publication" card now show a "View in Feed" ghost button that - navigates to the Feed screen. `ComposeScreen` now accepts an optional - `onNavigate` prop; `Shell` passes `setScreen` through. -17. **Last publish persisted across restarts (this session).** The most recent - publish report is now saved to `last_publish.json` in the data directory and - loaded on app startup. Added `StoredPublishReport` in `vault.rs`, `last_publish` - field on `App` and `AppStateView`, save on publish in `ipc.rs`, and - `last_publish` on the frontend `AppState` type. `AppProvider` initializes - `lastPublish` from `state.last_publish` so the Home screen shows the result - after a restart. -18. **Inline post preview on Home (this session).** The "Most recent publication" - card now shows the note content inline (compact summary) instead of a "View in - Feed" link. Added `content` field to `StoredPublishReport` and - `PublishReport`. Removed `onNavigate` prop from `ComposeScreen` and the - "View in Feed" button from both screens. Added `.publish-preview` CSS for the - content display. -19. **Fix: note preview now appears after publishing (this session).** The - "Most recent publication" card was not showing the note content preview - because the IPC handler returned the bare `PublishReport` (no `content` - field) instead of the `StoredPublishReport` that includes it. Changed - `src/ipc.rs` to return `stored` instead of `report`. -20. **Most Recent Publication shows only fully published events (this session).** - The "Most recent publication" box now queries relays for the active - profile's publications and determines per-event publication status by - comparing which relays served each event against all enabled relays. - Only the newest fully published event is shown in the main box. Partially - published events appear only in the expandable "Relay results" section. - Empty state shown when no fully published events exist. Added - `PublicationStatus` type, `computePublicationStatus()` helper, and - `useProfilePublications` hook. Rewrote `PublicationResult` in - `HomeScreen.tsx`. Added 10 new tests. +1. **Added unified Signer architecture** with a common `Signer` trait in `src/signer/mod.rs` + that both embedded and NIP-46 client implementations share. The trait provides: + - `get_public_key()`, `sign_event()`, `get_signer_type()`, `is_available()` + - `request_approval()`, `disconnect()`, `revoke()`, `status_string()`, `detailed_status()` + +2. **Embedded Signer mode** (`src/signer/embedded.rs`): + - Keys stored locally in the encrypted vault (Argon2id + AES-256-GCM) + - Zeroize memory protection for secret keys + - Per-request user approval with 5-minute timeout and 20-request queue cap + - Sensitive operations (kind 0, 3, 5, 6, 10000-10002, 30000-30015) flagged for extra confirmation + - Active profile binding with automatic updates on profile create/import/select + +3. **NIP-46 Client Signer mode** (`src/signer/nip46_client.rs`): + - Connects to external signer (bunker) via `nostrconnect://` URI + - Supports both local (separate process) and remote signers over relays + - NIP-44 v2 encryption for all communication + - Connection state tracking (connecting/connected/error) with relay connection monitoring + - Automatic approval timeout (5 min) and queue cap (20 pending) + - Connect secret echo verification per NIP-46 spec + - Graceful disconnect/revoke with connection cleanup + +3. **Signer mode management**: + - Users can choose "Embedded signer" or "NIP-46 signer" during account setup + - Switch modes anytime without changing public key (preserves `npub`) + - Clear UI showing active mode, connection status, and pending approvals + - Security notes explaining trade-offs between modes + +4. **Frontend integration**: + - New `SignerModeScreen.tsx` for mode selection and status monitoring + - Updated `AppProvider` with `signerModeGet`, `signerModeSet`, `embeddedSignerStatus`, + `nip46Connect`, `nip46Disconnect`, `nip46Status`, and approval handlers + - New types: `SignerMode`, `ApprovalDetails`, `EmbeddedSignerStatus`, `Nip46SignerStatus` + - Sidebar navigation updated with "Signer Mode" entry + +5. **IPC protocol extensions** (`src/ipc.rs`): + - `SignerModeGet`, `SignerModeSet` for mode management + - `EmbeddedSignerStatus`, `EmbeddedSignerApprove` + - `Nip46Connect`, `Nip46Disconnect`, `Nip46Status`, `Nip46Approve` + - Legacy bunker signer commands delegated to new NIP-46 client when in that mode + +6. **Security hardening**: + - All secret keys encrypted at rest with Argon2id + AES-256-GCM + - Zeroize for in-memory key cleanup + - Approval timeouts and queue caps prevent DoS + - Connection secrets verified on handshake + - No private keys in logs, crash reports, or network requests + - Keys never sent to server/relay/AI services ## Commits added in this session (newest first) -- `ea56806` fix: show only fully published events in Most Recent Publication box -- `577e9f4` fix: return StoredPublishReport with content to frontend after publish -- `cd5d2d7` Show published note content inline on Home screen -- `bab82f5` Persist last publish report across restarts -- `b0d9143` Add 'View in Feed' button after publishing a note -- `471acf8` polish: align HomeScreen spacing to design scale, add profile row hover -- `269f0c0` Remove identity card from HomeScreen — redundant with subtitle and profile list -- `566aa46` Remove redundant 'Active profile' heading from identity card -- `85ba088` fix(polish): clean up HomeScreen dead code and token drift -- `e854c95` fix(polish): remove identity card kicker, flatten to success border -- `ee13d47` fix(polish): align Compose button label with sidebar nav -- `32fc764` fix(polish): restore success-soft background on identity card -- `b05894e` fix(layout): redesign first-run guide with visual step indicators -- `96dcbe4` fix(polish): align HomeScreen with design system -- `e9022b3` fix(a11y): add keyboard accessibility to HomeScreen profile list -- `a47ce8b` checkpoint: document keyboard accessibility hardening -- `f1236e7` checkpoint: document clippy warning cleanup -- `3083a44` chore: fix two clippy warnings -- `0207636` feat: expose profile import over IPC -- `2604cf9` checkpoint: document release packages +- `b484bde` feat: add embedded signer and NIP-46 client signer modes ## Verification commands run All green in this session, run after the changes: -- Rust: `cargo fmt --check` clean;

Also adds the sha2 dependency.

the key never touches this machine. - Nip46Bunker: legacy inverted mode (Keynctr as signer serving others). Data model: - StoredProfile gains signer_mode (serde-defaults to Embedded for legacy profiles); SignerMode moves from app.rs to vault.rs to break a circular dependency; app.rs re-exports it. - Vault gains nip46_connections (profile-owned) and bumps VAULT_VERSION to 3; migrate_vault_signer_modes() normalises on load (idempotent). - Nip46Connection gains profile_npub ownership, parsed permissions, expires_at, and revoked_at. Signer abstraction (src/signer): - Signer trait gains pubkey_for() identity validation, a Signing enum (Local vs External) that re-verifies the returned event, and a permission surface (permissions/can_*/is_connection_valid) with safe defaults. - permissions.rs: NIP-46 per-connection permission model (parse, validate, deny-by-default, no-broadening checks) with 52 unit tests. - Nip46ClientSigner parses perms from nostrconnect:// URIs, enforces permissions on every gated request, persists/revokes connections in the vault, and audits permission denials via the app's audit log. - App gains audit_log and a nip46_bunker_signer handle; default mode is Nip46Client (most secure). Frontend: SignerModeScreen redesigned for the three modes with a nostr-tools-based SignerManager client, new IPC allowlist entries, and signer-mode styling.

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the plain reveal_secret_key flow with an explicit, audited key export that is hard to misuse: Backend (src/app.rs, src/ipc.rs): - New App::export_secret_key(): always requires the vault passphrase (even when the vault is already unlocked), requires a non-blank reason, and resolves the profile server-side via profiles::find_stored_profile. - Refuses export for Nip46Client (external) profiles — the secret key is not present locally — logging the denial. - FAIL-CLOSED: the successful audit entry is written and flushed BEFORE the key is returned; if the audit write fails, the key is not returned (log.record(...)? instead of let _ =). - Audit entries are written on every outcome: external-profile denial, wrong password, and the successful export. - RevealSecretKey IPC is deprecated: it now errors when the vault is locked and, when unlocked, records a [deprecated direct call] audit entry. The method stays registered for the deprecation window. Frontend: - ExportSecretKeyModal requires password + reason every time; clears sensitive state on close. - ProfilesScreen uses ExportSecretKeyModal; ShowSecretKeyModal and its test are removed. AppProvider exposes exportSecretKey (revealSecretKey gone); api.ts maps to export_secret_key. - fakeBackend implements the full export contract (profile-not-found, external-signer refusal, password check, blank-reason rejection); apiMock exposes exportSecretKey. 10 tests cover the required scenarios. No secret material is logged; the reason is logged by design. Verified: cargo test --release 186 passed; frontend tsc clean, vitest 116 passed. --- .../src/components/ExportSecretKeyModal.tsx | 209 ++++++++++++++ .../src/components/ShowSecretKeyModal.tsx | 188 ------------- frontend/src/lib/api.ts | 3 +- frontend/src/screens/ProfilesScreen.tsx | 4 +- frontend/src/state/AppProvider.tsx | 12 +- frontend/src/test/ExportSecretKey.test.tsx | 257 ++++++++++++++++++ frontend/src/test/ShowSecretKey.test.tsx | 87 ------ frontend/src/test/apiMock.ts | 4 +- frontend/src/test/fakeBackend.ts | 46 +++- src/app.rs | 77 ++++++ src/ipc.rs | 33 +++ 11 files changed, 629 insertions(+), 291 deletions(-) create mode 100644 frontend/src/components/ExportSecretKeyModal.tsx delete mode 100644 frontend/src/components/ShowSecretKeyModal.tsx create mode 100644 frontend/src/test/ExportSecretKey.test.tsx delete mode 100644 frontend/src/test/ShowSecretKey.test.tsx diff --git a/frontend/src/components/ExportSecretKeyModal.tsx b/frontend/src/components/ExportSecretKeyModal.tsx new file mode 100644 index 0000000..6aba1c4 --- /dev/null +++ b/frontend/src/components/ExportSecretKeyModal.tsx @@ -0,0 +1,209 @@ +import { useEffect, useRef, useState, type FormEvent } from 'react'; +import { BackendError } from '../lib/api'; +import { useApp } from '../state/AppProvider'; +import type { RevealedKey } from '../lib/types'; +import { Alert } from './Alert'; +import { Button } from './Button'; +import { CopyButton } from './CopyButton'; +import { ErrorText } from './ErrorText'; +import { Modal } from './Modal'; + +interface ExportSecretKeyModalProps { + open: boolean; + onClose: () => void; + profile: { label: string; npub: string } | null; +} + +type Phase = 'form' | 'exporting' | 'revealed' | 'error'; + +/** + * Exports a profile's secret key with fresh passphrase re-authentication. + * + * Every export requires the vault passphrase and a human-readable reason, + * regardless of whether the vault is already unlocked.

From 114b34319e06e97551b7f77c18794b8f5f09b70e Mon Sep 17 00:00:00 2001 From: Avi Date: Thu, 3 Sep 2026 13:12:58 -0500 Subject: [PATCH 39/48] fix(packaging): restore Linux app icon so dist builds ship an icon The packaging break: 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 instead of the Keynctr mark. Regenerate build/icon.png from KeynectrAppIconPossibility02.jpeg rather than resizing the old file: - cut the white (254) JPEG background to transparent (alpha from luma), - flatten the art to a square canvas with symmetric padding, - keep the ink pure black (RGB 0,0,0), export 512x512 RGBA. The 512x512 master satisfies both declared linux targets with the config kept single (linux.icon: build/icon.png, no build/linux/ fan-out): - AppImage: electron-builder downscales to 256 internally (>=256 required). - deb: installs usr/share/icons/hicolor/512x512/apps/keynectr.png, matching the generated .desktop Icon=keynectr. Verified end to end (npm run dist green): the embedded icon is byte-identical (md5 b3e372f7) in the AppImage hicolor set, the AppImage .DirIcon, and the deb hicolor set, all 512x512 RGBA with real transparency. The source JPEG (KeynectrAppIconPossibility02.jpeg) stays untracked, as does the pre-existing hygiene leftover set. No package.json change needed: the single build/icon.png path is already correct. --- frontend/build/icon.png | Bin 11216 -> 10912 bytes 1 file changed, 0 insertions(+), 0 deletions(-) diff --git

From e6e49222ea16c2c60ae746d6795a58e4e2d7b65a Mon Sep 17 00:00:00 2001 From: Avi Date: Thu, 3 Sep 2026 15:52:25 -0500 Subject: [PATCH 41/48] feat(signer): add SigningBackend + SigningError + VaultRef MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce the Step-3 signing-abstraction types: - SigningBackend { Internal, Remote { vault_ref } } — the per-profile choice of where user content is signed. Remote holds ONLY an opaque VaultRef (profile_npub + signer_pubkey); the NIP-46 connection secret is never inlined, so a serialized or leaked backend can never hand a raw secret to a renderer, the audit log, or a crash dump. - VaultRef — opaque, secret-free pointer into the vault's encrypted connection-secret store (resolves to the decrypted secret only at the vault boundary, while unlocked). - SigningError — closed set of signing failures with a stable ErrorKind, user-facing message, and optional technical detail; converts to AppError at the IPC boundary via From, plus a best-effort from_app lift. 10 unit tests, incl. the constraint that serializing a Remote backend never emits a secret. This is the foundation commit; vault integration and IPC rerouting land in follow-ups. --- src/signer/backend.rs | 490 ++++++++++++++++++++++++++++++++++++++++++ src/signer/mod.rs | 3 + 2 files changed, 493 insertions(+) create mode 100644 src/signer/backend.rs diff --git a/src/signer/backend.rs b/src/signer/backend.rs new file mode 100644 index 0000000..86b8b14 --- /dev/null +++ b/src/signer/backend.rs @@ -0,0 +1,490 @@ +//!

Resolution to the decrypted secret happens only at the vault - boundary, while the vault is unlocked (that wiring is the next sub-step). -- `SigningError` — the closed set of signing failures (no active profile, internal key - unavailable, remote connection missing, secret resolution, identity mismatch, not - connected, permission denied, expired, revoked, rejected, timeout, invalid signature, - network, storage, internal). Each carries a stable `ErrorKind`, a user-facing message - (mirroring the existing `AppError` copy), and an optional technical detail. - `From for AppError` converts at the IPC boundary; a best-effort - `SigningError::from_app` lifts upstream `AppError`s back into the signing space. +- **`src/vault.rs`** — new `ConnectionSecret { ref_: VaultRef, secret }` struct and a + `Vault.connection_secrets: Vec` 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.

fix(icons): true alpha channel, no white matte or white tile - public/icon.png and src/assets/logo.png were grayscale (mode L): a flat white field, no alpha, which rendered as a white box/halo on every non-white surface (window/taskbar icon, sidebar, launchers) - regenerate both as RGBA: alpha is the ink coverage, RGB forced to 0 so no white matte can leak through semi-transparent edge pixels - styles.css: drop the white tile background/border-radius and cover-fit from .sidebar-logo; the artwork now composites directly (contain-fit) - originals preserved under deferred/original-icons/ ---

Linux display compatibility + icon alpha fixes (2026-09-09) + +## Where things are +- Project: `/home/avi/Projects/Keynctr` +- Branch: `master` @ **`d580139`** ("fix(icons): true alpha channel, no white matte or + white tile") on top of **`0814a53`** ("fix(linux): work on X11, Wayland, and Hyprland"). +- Working tree: **clean for tracked files.** Untracked leftovers are the pre-existing + hygiene entries (`.directory`, `.impeccable/`, `.opencode/`, `COSMIC_THEME.md`, + `src/publish.rs.bak`, `src/signer/nip46_external.rs`) plus `deferred/SignerConnectionPanel.tsx.wip` + (a broken WIP component, moved out of the build — see below). Original white-background + icons are preserved under `deferred/original-icons/` (tracked). + +## What was completed (this session) + +### 1. Linux display-server compatibility — `0814a53` + +The app did not start on a friend's Wayland machine. Root causes found and fixed: + +- **No explicit platform choice.** Hyprland (and any Wayland session with XWayland) + exports both `$DISPLAY` and `$WAYLAND_DISPLAY`, so Electron must be told which + backend to use before Chromium initializes. `frontend/electron/main.ts` now sets + `ozone-platform` (wayland/x11) from `XDG_SESSION_TYPE`/`WAYLAND_DISPLAY` at module + load, with `KEYNCTR_FORCE_X11=1` / `KEYNCTR_FORCE_WAYLAND=1` overrides. +- **GPU process crashes (SIGSEGV in `eglCreateWindowSurface`, Mesa `libGLESv2`).** + Reproduced on this box (Intel Iris Xe, Hyprland, mesa 26.2.1): with hardware GL the + GPU helper died repeatedly and the window never appeared. Fix: **software rendering + by default on Linux** (`app.disableHardwareAcceleration()`); hardware GL is opt-in + via `KEYNCTR_ENABLE_GPU=1`. +- **Startup watchdog + bounded relaunch ladder.** A marker file + (`/keynctr-startup.json`, stamped clean on deliberate quit) records each launch; + if the previous process died before its window proved itself (painted and survived + 8 s), the next launch advances one rung: detected platform → other platform → GPU + opt-in → other+GPU, then stops with an error dialog listing the escape hatches. + AppImage-safe relaunch via `$APPIMAGE`. No infinite cascades. +- **Sandbox pre-flight.** Packaged builds check for a non-setuid `chrome-sandbox` + combined with blocked unprivileged user namespaces (Ubuntu 24.04 AppArmor knob, + `unprivileged_userns_clone`) and fall back to `--no-sandbox` instead of dying + silently. Root also gets `--no-sandbox` as Chromium requires. +- Window now uses `show: false` + `ready-to-show` (always shown, even with the + watchdog disabled). + +### 2. Icon white-fringe fix — `d580139` + +The source icons were grayscale (mode **L**, no alpha at all): a black bird on a flat +white field, which rendered as a white box/halo on every non-white surface (window +icon, taskbar, sidebar, launchers). + +- `frontend/public/icon.png` and `frontend/src/assets/logo.png` regenerated as + **RGBA**: alpha = ink coverage of the original artwork; RGB forced to 0 everywhere, + so no white matte can bleed through semi-transparent edge pixels (verified: 0 pixels + with RGB > 200 at alpha < 20). Artwork bbox/shape unchanged (IoU 1.0 vs originals). +- `frontend/src/styles.css`: `.sidebar-logo` dropped its `background: #fff` white tile, + `border-radius`, and `object-fit: cover`; the artwork now composites directly with + `contain`. Dark-theme `invert(1)` kept (ink artwork must flip on dark sidebars). +- Originals preserved: `deferred/original-icons/icon-public-512-white.png`, + `deferred/original-icons/logo-sidebar-338-white.png`. + +### 3. Build hygiene (uncommitted by design? no — landed with the fixes) + +- `frontend/src/components/signer/SignerConnectionPanel.tsx` was an untracked, + non-compiling WIP (broken `useCallback` closures, APIs that don't exist on + `SignerManager`, dependency on uninstalled `react-router-dom`) that blocked + `npm run typecheck`. Moved intact to `deferred/SignerConnectionPanel.tsx.wip` + (untracked) — nothing deleted; it needs a rewrite against the real hooks before + returning. + +## Verification (all run this session) + +- Rust: `cargo fmt --check` clean, `cargo clippy --all-targets` clean, `cargo test` + green, `cargo build --release` succeeded. +- Frontend: `npm run electron:build`, `npm run typecheck`, `npm run lint` clean; + `npm test` **116/116 passed**; `npx prettier --check electron/main.ts` and + `src/styles.css` clean; `npm run build` succeeded. (5 pre-existing Prettier warnings + in untouched files — `ExportSecretKeyModal.tsx`, `SignerModeScreen.tsx`, + `AppProvider.tsx`, `ExportSecretKey.test.tsx`, `fakeBackend.ts` — predate this + session and were left alone.) +- **On-device (Hyprland/Wayland, this machine):** app launched under a clean systemd + user scope: Keynctr window mapped (`class: keynectr`), watchdog marker cleared + (= config proven), **no new Electron core dumps** after 19:40 while multiple + software-render launches ran. `grim` screenshot + visual inspection confirmed the + sidebar bird sits directly on the sidebar with **no white tile, border, or halo**. +- Icon proof: checkerboard composite of the new `public/icon.png` shows clean + anti-aliased edges into transparency, no white fringe. + +## How to run / reproduce + +- GUI: `cd frontend && npm start` (or the packaged AppImage/deb once rebuilt via + `npm run dist`). +- Escape hatches: `KEYNCTR_FORCE_X11=1`, `KEYNCTR_FORCE_WAYLAND=1`, + `KEYNCTR_ENABLE_GPU=1`, `KEYNCTR_DISABLE_GPU=1`, `KEYNCTR_NO_RELAUNCH=1`. +- CLI: `cargo run --release -- serve` (JSON-lines IPC) as before. + +## Outstanding / next steps + +- **Repackage for the friend:** `npm run dist` (AppImage + deb) with the new icon and + display fixes; the old `frontend/release/` artifacts predate both commits. +- `deferred/SignerConnectionPanel.tsx.wip`: rewrite against the real `useSignerManager` + API (+ either add `react-router-dom` or drop the import) before reinstating. +- Consider a taskbar-visible test on a pure-X11 session and on GNOME Wayland for the + friend matrix (only Hyprland/Wayland was verifiable here). +- Step 3 sub-step 2 (IPC reroute) is untouched and remains the next signer milestone. +- The user's crash-reporter still holds old core dumps from pre-fix launches + (`coredumpctl rm` clears them).
