# Project State

## 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 2 in progress — Plan 01 complete (vault core + highlighter foundation)

## Current Position

Phase: 2 of 4 (Vault Core and Rendering) — IN PROGRESS
Plan: 1 of 3 in current phase (plan 01 done)
Status: Phase 2 Plan 01 complete — Plan 02 (markdown renderer) next
Last activity: 2026-02-28 — Plan 01 complete (deps, vault.rs, highlighter.rs)

Progress: [████░░░░░░] 33%

## Performance Metrics

**Velocity:**
- Total plans completed: 4
- Average duration: 2.2 min
- Total execution time: 0.14 hours

**By Phase:**

| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 01-safety-foundation | 3 | 7 min | 2.3 min |
| 02-vault-core-and-rendering | 1 | 2 min | 2.0 min |

**Recent Trend:**
- Last 5 plans: 2 min, 3 min, 2 min, 2 min
- Trend: Stable

*Updated after each plan completion*

## 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 omitted from main.rs — Plan 03 handles wiring for all Phase 2 modules
- 02-01: syntect default-fancy feature uses pure-Rust fancy-regex (avoids Oniguruma C lib)

### Pending Todos

None.

### Blockers/Concerns

- **REND**: ratatui 0.30 Widget trait confirmed: `impl Widget for &Foo` pattern required (NOT WidgetRef) — Plan 02 must use reference-based impl
- **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
