 - Pre-Phase 1: Use pulldown-cmark event-based approach for markdown parsing (not comrak)
 - Pre-Phase 1: No tokio/async runtime — synchronous event loop only
 - Pre-Phase 2: Choose wiki-link parsing strategy before implementation (regex pre-pass vs post-parse interception)
+- 01-01: Resolve relative vault_path against config file parent dir (not cwd) — bbs.toml lives next to binary
+- 01-01: detect_login_shell() called before parse_cli() — both read argv[0], parse_cli strips the dash
+- 01-02: Use ratatui::crossterm re-export path — crossterm is transitive dep, not direct dep in Cargo.toml
+- 01-02: SIGINT not registered via signal-hook — crossterm key events handle double-press Ctrl+C in Plan 03
+- 01-02: restore_terminal() skips ratatui::restore() — that would call LeaveAlternateScreen (never entered)

 ### Blockers/Concerns
 
-- **LIFE**: Panic hook and SIGHUP handling are highest priority — must land before any feature code
 - **REND**: Verify ratatui 0.30 custom Widget trait signature before building BBS widgets (changed between 0.28 and 0.29)
 - **NAV**: Path traversal via wiki-links must be addressed in Phase 3 link resolver — canonicalize and prefix-check every resolved path
 - **LIVE**: notify 8.x API must be verified at integration time; watch only current file (not full vault) to avoid inotify exhaustion
