## Goal Achievement
|
||
|
||
### Observable Truths
|
||
|
||
The 17 must-have truths are drawn directly from the three plan frontmatter `must_haves` sections.
|
||
|
||
#### Plan 02-01 Truths (Foundation)
|
||
|
||
| # | Truth | Status | Evidence |
|
||
|---|-------|--------|----------|
|
||
| 1 | pulldown-cmark, syntect, and syntect-tui compile without errors alongside existing ratatui 0.30 | VERIFIED | `cargo build` succeeds with 1 pre-existing warning (signals.rs dead_code), zero errors; Cargo.toml has all three dependencies at specified versions |
|
||
| 2 | vault.rs can load a markdown file from a vault path and return structured success/missing/error states | VERIFIED | `load_document()` uses `std::fs::read_to_string`, matches on `ErrorKind::NotFound` for `Missing`, all other errors to `ReadError`, success to `Loaded` |
|
||
| 3 | highlighter.rs initializes syntect once and can highlight a code string into Vec<Line<'static>> with CGA 16-color palette | VERIFIED | `OnceLock<SyntaxSet>` and `OnceLock<ThemeSet>` statics; `highlight_code()` returns `Vec<Line<'static>>` with all-owned Span strings; full 16-entry CGA palette in `syntect_color_to_cga()` |
|
||
|
||
#### Plan 02-02 Truths (Renderer)
|
||
|
||
| # | Truth | Status | Evidence |
|
||
|---|-------|--------|----------|
|
||
| 4 | Headings H1-H6 render with distinct CGA colors and decorators (H1=LightCyan+══, H2=LightYellow+──, H3-H6 color-only) | VERIFIED | `start_heading()` assigns correct CGA colors per level; `end_heading()` emits `═`.repeat(w) for H1, `─`.repeat(w) for H2, nothing for H3-H6 |
|
||
| 5 | Bold text uses Modifier::BOLD, italic uses Modifier::ITALIC, inline code uses LightCyan styling | VERIFIED | `Tag::Strong` pushes `Modifier::BOLD`, `Tag::Emphasis` pushes `Modifier::ITALIC`, `Event::Code` emits `Style::default().fg(Color::LightCyan)` span |
|
||
| 6 | Fenced code blocks render with rounded box-drawing borders (╭─╮│╰─╯) and syntax-highlighted content via highlighter.rs | VERIFIED | `emit_code_block()` at line 439 uses `╭`, `│`, `╰`, `╮`, `╯`; calls `crate::highlighter::highlight_code(code_buf, lang)` at line 445 |
|
||
| 7 | Ordered and unordered lists render with bullets/numbers and proper indentation per nesting depth | VERIFIED | `list_counters: Vec<Option<u64>>` tracks nesting; bullets use `•`/`◦`/`▪` per depth level; ordered lists format `{n}. ` and increment counter |
|
||
| 8 | Blockquotes render with a yellow │ left border and gray content | VERIFIED | `flush_line()` prepends `Span::styled("│ ".repeat(depth), Style::default().fg(Color::Yellow))` and re-colors content spans to `Color::Gray` when `in_blockquote` |
|
||
| 9 | Horizontal rules render as full-width ─── lines in DarkGray | VERIFIED | `Event::Rule` emits `"─".repeat(state.width as usize)` styled `Color::DarkGray` |
|
||
| 10 | Images render as [IMAGE: alt text] placeholders in DarkGray+DIM | VERIFIED | `End(TagEnd::Image)` emits `format!("[IMAGE: {}]", alt)` with `Color::DarkGray` and `Modifier::DIM` |
|
||
| 11 | GFM tables render with full box-drawing grid (┌┬┐├┼┤└┴┘) and bold LightCyan header row | VERIFIED | `emit_table()` uses `build_border()` with `┌`,`┬`,`┐`,`├`,`┼`,`┤`,`└`,`┴`,`┘`; header uses `Color::LightCyan + Modifier::BOLD` |
|
||
|
||
#### Plan 02-03 Truths (App Integration)
|
||
|
||
| # | Truth | Status | Evidence |
|
||
|---|-------|--------|----------|
|
||
| 12 | App starts and displays index.md content from the configured vault_path | VERIFIED | `main.rs` calls `vault::load_document(&app_config.vault_path, "index.md")`, renders via `renderer::render_markdown()`, passes to `App::new()` |
|
||
| 13 | When index.md is missing, user sees a BBS-style error screen with box-drawing border and helpful message | VERIFIED | `draw_error_screen()` renders a centered red-bordered `Block` with "*** SYSTEM ERROR ***" in LightRed+BOLD, path in Yellow, hint in DarkGray |
|
||
| 14 | User can scroll content with j/k (one line), arrow keys (one line), PgUp/PgDn (full page) | VERIFIED | `handle_key()` matches `KeyCode::Char('j') \| KeyCode::Down`, `Char('k') \| KeyCode::Up`, `PageDown`, `PageUp`; each calls `scroll_down`/`scroll_up` with 1 or `page_height()` |
|
||
| 15 | Status bar at the bottom shows filename on the left and keyboard hints on the right in reverse video | VERIFIED | `draw_status_bar()` builds left+padding+right Line, renders `Paragraph` with `Style::default().add_modifier(Modifier::REVERSED)` |
|
||
| 16 | Terminal resize re-renders content at new width and reflows layout without crashing | VERIFIED | `Event::Resize(w, _h)` triggers `handle_resize(w)` which calls `crate::renderer::render_markdown(content, new_width)` and clamps `scroll_offset` to new `max_scroll()` |
|
||
| 17 | Quit behavior from Phase 1 (q key, double Ctrl+C) is preserved | VERIFIED | `handle_key()` retains the double Ctrl+C state machine with `DOUBLE_PRESS_WINDOW`; `q` key guarded by `!self.is_login_shell`; `show_goodbye()` and `ShutdownReason` unchanged |

||
|----------|-----------|--------|---------|

|
||

|
||
| `src/highlighter.rs` | — | VERIFIED | `OnceLock<SyntaxSet>`, `OnceLock<ThemeSet>`; `init_highlighter()`, `syntax_set()`, `theme_set()`, `syntect_color_to_cga()`, `highlight_code()`; full 16-entry CGA palette; `LinesWithNewlines` iterator |
|
||
| `src/renderer.rs` | 200 | VERIFIED | 703 lines; `render_markdown()` public API; `RenderState` struct; `emit_code_block()` and `emit_table()` free functions; handles all Event variants |
|
||
| `src/app.rs` | — | VERIFIED | `DocumentState` enum; `App` with Phase 2 fields; `draw()`, `draw_status_bar()`, `draw_error_screen()`, `handle_key()`, `handle_resize()`, scroll helpers; all Phase 1 behavior preserved |
|
||
| `src/main.rs` | — | VERIFIED | All 7 `mod` declarations; `highlighter::init_highlighter()` before `render_markdown()`; vault loading with all three match arms; `raw_content` passed to `App::new()` |
|

### Key Link Verification
|
||
|
||
| From | To | Via | Status | Details |
|
||
|------|----|-----|--------|---------|
|
||
| `src/highlighter.rs` | syntect | `OnceLock<SyntaxSet>` and `OnceLock<ThemeSet>` statics | WIRED | Lines 10-11: `static SYNTAX_SET: OnceLock<SyntaxSet>` and `static THEME_SET: OnceLock<ThemeSet>` |
|
||
| `src/vault.rs` | `std::fs` | `read_to_string` for markdown file loading | WIRED | Line 31: `match std::fs::read_to_string(&full_path)` |
|
||
| `src/renderer.rs` | pulldown-cmark | `TextMergeStream` consuming all `Event` variants | WIRED | Line 696: `let parser = TextMergeStream::new(Parser::new_ext(input, opts))` |
|
||
| `src/renderer.rs` | `src/highlighter.rs` | `highlight_code()` called for fenced code blocks | WIRED | Line 445: `crate::highlighter::highlight_code(code_buf, lang)` |
|
||
| `src/renderer.rs` | ratatui::text | Produces `Vec<Line<'static>>` with Span styling | WIRED | Return type of `render_markdown()` and all emitter functions confirmed `Vec<Line<'static>>` |
|
||
| `src/main.rs` | `src/highlighter.rs` | `init_highlighter()` called before `App::new()` | WIRED | Line 32: `highlighter::init_highlighter()` at step 3a, before step 7 `App::new()` |
|
||
| `src/main.rs` (via app.rs) | `src/vault.rs` | `load_document()` called in startup to get markdown content | WIRED | Line 41: `vault::load_document(&app_config.vault_path, "index.md")`; result passed as `DocumentState` to `App::new()` |
|
||
| `src/app.rs` | `src/renderer.rs` | `render_markdown()` called on resize to re-render at new width | WIRED | Line 204: `crate::renderer::render_markdown(content, new_width)` in `handle_resize()` |
|
||
| `src/app.rs` | `ratatui::widgets::Paragraph` | `Paragraph::new(lines).scroll((offset, 0))` for scrollable content | WIRED | Lines 332-334: `Paragraph::new(lines.clone()).scroll((self.scroll_offset, 0))` |
|
||
|
||
**Note on plan 02-03 key link `app.rs -> vault.rs`:** The plan specified `load_document()` called from `src/app.rs`, but the implementation calls it from `src/main.rs` and passes the result as `DocumentState` to `App::new()`. This is a valid architectural choice — cleaner separation of concerns — and the goal truth ("App starts and displays index.md content") is fully satisfied. The load path is: `main.rs` -> `vault::load_document()` -> `renderer::render_markdown()` -> `App::new(DocumentState::Loaded)`.

|
||
|
||
**All 15 required requirement IDs accounted for. No orphaned requirements.**
|
||
|
||
REQUIREMENTS.md traceability table marks REND-03, REND-10, NAV-05, NAV-06, NAV-07, NAV-08, NAV-09 as "Complete" and REND-01, REND-02, REND-04, REND-05, REND-06, REND-07, REND-08, REND-09 as "Pending" — the checkbox status in REQUIREMENTS.md is inconsistent with actual implementation, but the traceability table correctly maps all 15 IDs to Phase 2. The code implements all 15.

|
||
### Anti-Patterns Found
|
||
|
||
| File | Line | Pattern | Severity | Impact |
|
||
|------|------|---------|----------|--------|
|
||
| `src/renderer.rs` | 356-358 | `placeholder` string | Info | Intentional: the `[IMAGE: alt text]` placeholder is the correct implementation of REND-07, not a stub |
|
||
|
||
No blocker or warning anti-patterns found. `cargo build` output: 1 pre-existing warning (`init_logging` dead_code in `signals.rs` — not introduced by Phase 2), zero errors.

||
### Human Verification Required
|
||
|
||
The following behaviors require a running terminal session to confirm visually:
|
||
|
||
#### 1. Markdown Rendering Visual Quality
|
||
|
||
**Test:** Create a vault with `index.md` containing H1-H6 headings, bold/italic text, a fenced code block with `rust` language tag, an unordered list, a blockquote, a horizontal rule, an image reference, and a GFM table. Run `cargo run`.
|
||
**Expected:** Each element renders with distinct CGA colors; H1 has a `═` decorator, H2 has a `─` decorator; code block has `╭─ rust ─╮` top border with syntax-highlighted content; table has `┌┬┐` grid; blockquote has yellow `│` left border.
|
||
**Why human:** Visual styling and color accuracy cannot be verified without a running terminal.
|
||
|
||
#### 2. Scrolling Feel
|
||
|
||
**Test:** Load a document longer than the terminal height. Press j, k, PgDn, PgUp, and arrow keys.
|
||
**Expected:** Content scrolls smoothly; scroll stops at top and bottom of document without overshooting.
|
||
**Why human:** `max_scroll()` clamping logic is verified in code, but the user experience of scrolling (responsiveness, no flicker) requires a live terminal.
|
||
|
||
#### 3. Status Bar Display
|
||
|
||
**Test:** Observe the bottom line of the terminal.
|
||
**Expected:** Filename appears left-aligned, keyboard hints right-aligned, entire bar is reverse-video (text and background inverted). Quit prompt replaces hints when Ctrl+C is pressed once.
|
||
**Why human:** `Modifier::REVERSED` rendering depends on terminal emulator support; visual verification required.
|
||
|
||
#### 4. Missing index.md Error Screen
|
||
|
||
**Test:** Configure vault_path to a directory without `index.md`. Run `cargo run`.
|
||
**Expected:** Centered box with red border, `*** SYSTEM ERROR ***` in bright red, vault directory path in yellow, `Create index.md to begin.` hint in dark gray.
|
||
**Why human:** Visual centering calculation and color rendering require live terminal.
|
||
|
||
#### 5. Terminal Resize Re-render
|
||
|
||
**Test:** While running with a wide terminal, resize the terminal window to half width.
|
||
**Expected:** Horizontal rules shrink to new width; code block borders reflow; no crash; scroll offset clamped if needed.
|
||
**Why human:** Resize event behavior requires interactive session.
