-# Checkpoint — Release packages with profile metadata fix (2026-09-01)

 ## Where things are
-- Project: `/home/avi/Projects/Keynctr`
+- Project: `/home/avi/Projects/Nostr_Keynctr`
-- Git repo: `master` @ `3107508` ("fix: query imported metadata by relay").
+- Git repo: `master` @ `76deca6` ("feat: add Cosmic theme + motion system").
-- Working tree: intended profile metadata fix is committed; unrelated UI/branding changes remain uncommitted and untracked.
+- Working tree: uncommitted Keynctr branding, packaging metadata, and Cosmic palette/branding updates, plus untracked `.directory`, `.opencode/`, `COSMIC_THEME.md`, and `KeynectrAppIconPossibility02.jpeg`.
 
 ## What was completed
 1. **Cosmic branding update.** The Cosmic theme now uses Gold `#F3B407` and Light Blue `#87E6FB`; Cosmic’s dark sidebar presents the logo in white while retaining black-on-white artwork elsewhere. The visible brand is `SOLARPUNK SUMMIT` with `KITCHEN 484`.

 6. **Keynctr branding.** Replaced the visible `SOLARPUNK SUMMIT` / `KITCHEN 484` labels with `Keynctr` in the window, page title, sidebar, home screen, settings, and tests. Rebuilt artifacts: `frontend/release/Keynctr-0.1.0.AppImage` and `frontend/release/keynectr_0.1.0_amd64.deb`.
 
 ## Commits added in this session (newest first)

-- `bde35bc` fix: import existing profile metadata
-- `d2d773a` fix: remove Stardust background dots
-- `7605f51` fix: keep NIP-46 signer subscription open
 - `76deca6` feat: add Cosmic theme + motion system (palette/branding refinements currently uncommitted)
 - `8366af7` feat: add Impeccable themes (light + dark) + unified ProfileEditModal

 - Branding verification: `npm test`, `npm run typecheck`, `npm run lint`, `npm run format:check`, `npm run electron:build`, `npm run build`, and `npx electron-builder --linux AppImage deb` passed.
 - Frontend build no longer reports the Cosmic font `@import` ordering warning; standard Vite/ESM and ESLint module warnings remain.
 - Wayland `--ozone-platform` / `has no handler` messages on `electron:build` are harmless.
-- NIP-46 fix: use a persistent subscription instead of the auto-closing `stream_events` helper, so clients can send requests after EOSE.
-- Stardust verification: `npm test` (99 passed), `npm run typecheck`, `npm run lint`, `npm run electron:build`, and `npm run build` passed. `npm run format:check` still reports existing issues in three unrelated frontend files.
-- Existing-account import verification: `cargo test` (115 passed), `cargo clippy --all-targets`, `cargo fmt --check`, `cargo build --release`, `npm test` (99 passed), `npm run typecheck`, `npm run lint`, `npm run electron:build`, and `npm run build` passed. `npm run format:check` reports existing issues in three frontend files.
-- Imported account naming: the name field is no longer required; kind-0 `display_name`/`name` is used automatically, with a shortened npub fallback. Verification: `cargo test` (116 passed), `cargo clippy --all-targets`, `cargo fmt --check`, `cargo build --release`, `npm test` (99 passed), `npm run typecheck`, `npm run lint`, `npm run electron:build`, and `npm run build` passed. `npm run format:check` still reports existing issues in three frontend files.
-- Corrected metadata lookup to query with the derived public-key type directly, preventing silent fallback when importing accounts.
-- Release verification: Rust test suite (116 passed), clippy, fmt, release build, frontend tests (99 passed), typecheck, lint, Electron build, production build, and AppImage/Debian packaging passed. Frontend format check retains three existing warnings.
 
 ## How to resume / reproduce
 GUI (Cosmic): `cargo build --release && cd frontend && npm run build && npm run electron:build && npm start` (or dev: `npm run dev` in one terminal + `NOSTR_GUI_DEV_URL=http://localhost:5173 npm start` in second). Settings → Appearance → `Cosmic — Stardust`. CLI: `cargo run -- settings set theme cosmic`.
 - Build installers: `cd frontend && npm run build && npm run electron:build && npx electron-builder --linux AppImage deb`. Install the `.deb` with `sudo apt install ./release/keynectr_0.1.0_amd64.deb`, or run the AppImage with `./release/SOLARPUNK\ SUMMIT-0.1.0.AppImage`.
 - Current installers: `sudo apt install ./release/keynectr_0.1.0_amd64.deb`, or `./release/Keynctr-0.1.0.AppImage`.
-- Signer GUI: unlock vault, open `Signer`, select remote signer in the client, paste its `nostrconnect://` URI, then approve requests. CLI: `cargo run --release -- signer connect <nostrconnect://...>`.
-- Stardust GUI: select `Settings -> Appearance -> Cosmic - Stardust`, then restart the frontend to load the updated CSS bundle.
-- Import GUI: restart after rebuilding, open `Profiles -> Add existing account`, enter only the private key, and Keynctr will derive the profile name and metadata from the network.
-- Release artifacts: `frontend/release/Keynctr-0.1.0.AppImage` and `frontend/release/keynectr_0.1.0_amd64.deb`, verified with `file`.
 
 ## Outstanding / next-step items
 - Undo restores with empty `secret_key` (stores `ProfileSummary`); needs `StoredProfile` in `undo_history` for full secret recovery.
