Project Reference

See: .planning/PROJECT.md (updated 2026-02-28)

Core value: Users can connect via SSH and seamlessly browse a vault of linked markdown documents with retro BBS aesthetics Current focus: Phase 3 COMPLETE — Plans 01 and 02 done (navigation, history, Tab-cycling, breadcrumbs all wired)

Current Position

Phase: 3 of 4 (Navigation and Links) — COMPLETE Plan: 2 of 2 in current phase (03-01 done, 03-02 done) Status: 03-02 complete — navigation history, link cycling, breadcrumb status bar implemented Last activity: 2026-02-28 — Plan 02 complete (HistoryEntry, navigate_to/back/forward, Tab-cycling, REVERSED highlight, breadcrumb)

Progress: [██████████] 100%

Performance Metrics

Velocity:

• Total plans completed: 7
• Average duration: 2.8 min

01-safety-foundation	3	7 min	2.3 min
02-vault-core-and-rendering	3	9 min	3.0 min
03-navigation-and-links	2	7 min	3.5 min

Recent Trend:

• Last 5 plans: 3 min, 2 min, 2 min, 4 min, 3 min

Accumulated Context

Decisions

Decisions are logged in PROJECT.md Key Decisions table. Recent decisions affecting current work:

• Pre-Phase 1: Verify edition = "2024" compiles before changing to 2021 — leave it if cargo build succeeds
• 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)
• 01-03: show_goodbye() called after restore_terminal() — terminal must be in cooked mode before println! is safe
• 01-03: app_config stored in App struct for Phase 2 access — vault_path accessible inside event loop
• 01-03: Quit prompt cleared on any non-Ctrl+C key — pressing any key dismisses double-press window
• 02-01: LinesWithNewlines iterator added to preserve trailing \n for syntect grammar correctness
• 02-01: mod declarations added to main.rs during Plan 02 (not Plan 03) — compiler needs them to check renderer.rs
• 02-01: syntect default-fancy feature uses pure-Rust fancy-regex (avoids Oniguruma C lib)
• 02-02: Full emit_code_block and emit_table written in Task 1 (not stubs) — avoids throwaway code
• 02-02: Box width for code blocks capped at terminal width — prevents border overflow on long lines
• 02-02: Table n_cols derived from max(alignments.len(), max row length) — handles malformed GFM tables
• [Phase 02-03]: raw_content stored in App for resize re-render — avoids disk re-read on window resize
• [Phase 02-03]: draw_error_screen() unified for Missing and Error via Option<&str> reason parameter
• [Phase 02-03]: Scroll keys placed before _ catch-all — j/k during quit prompt does not dismiss it
• [Phase 03-navigation-and-links]: vault_path added to render_markdown for render-time broken wiki-link detection
• [Phase 03-navigation-and-links]: Broken wiki-links checked at render time; standard links deferred to navigation time
• [Phase 03-navigation-and-links]: link_span_start_count field tracks span array position at Tag::Link Start for span_len computation
• [Phase 03-02]: navigate_to does NOT push to history on Missing/ReadError — user stays on current page conceptually
• [Phase 03-02]: navigate_back/forward re-loads from disk (no render cache) per research recommendation
• [Phase 03-02]: Draw-time REVERSED uses lines.clone() per frame — stored lines unchanged for resize re-render
• [Phase 03-02]: Span overlap detection extended beyond plan spec — catches spans starting before col_offset that extend into link range

Pending Todos

None.

Blockers/Concerns

• REND blocker resolved: renderer.rs uses no Widget trait at all — render_markdown() returns Vec<Line<'static>> which Plan 03 passes to Paragraph::new(). No custom Widget needed.
• NAV path traversal resolved: is_within_vault() with canonicalize + starts_with guards all link resolution in vault.rs
• LIVE: notify 8.x API must be verified at integration time; watch only current file (not full vault) to avoid inotify exhaustion
