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

Score: 17/17 truths verified

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/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.
