 # Rich Markdown Renderer — Phase 2: Tables + List Wrapping
 **Status:** Planning complete, awaiting Momus review before implementation.
 **Owner:** Coyote maintainer
 **Estimated effort:** 3-4 days (tables + hanging-indent wrapping for lists/blockquotes)
 **Related:** [Phase 1 plan](./rich-markdown-renderer.md) — must be complete first (it is).
 ---
 ## Goals
 1. **Tables:** render GFM markdown tables (`| col | col |` with `|---|---|` separator rows) as styled terminal tables using box-drawing characters, respecting per-column alignment specifiers and the user's syntect theme colors. Match glamour's structural rendering (box borders, header separator, aligned cells). Cell content wraps within the column boundary.
 2. **List wrapping:** when a bullet/numbered/task list item's content is longer than the wrap width, wrap it with a **hanging indent** so continuation lines align under the text, not under the bullet marker. Same treatment for blockquotes — continuation lines get the `│ ` prefix.
 ## Non-Goals
 - **Not shipping without `comfy-table` dependency.** Hand-rolling table rendering requires reimplementing width-aware unicode + ANSI-aware column sizing. `comfy-table 7.2.2` already does this correctly (`ansi_strip().width()`) and is actively maintained (Jan 2026). See "Library decision" below.
 - **Not supporting non-GFM table syntaxes.** Multi-line cells, cell merging, nested tables, and reStructuredText-style grid tables are out of scope. Standard GFM `|` + `---` only.
 - **Not showing partial tables during streaming.** Tables accumulate silently while rows arrive; the rendered table appears once when the block ends. Users see a brief pause during accumulation instead of a flashing raw→rendered transition. Matches glamour behavior.
 - **Not preserving the "zero touches outside `markdown.rs`" Phase 1 principle** — see "Scope-Expansion Rationale" below.
 ## Scope-Expansion Rationale
 Phase 1 held two principles that Phase 2 must relax, both with clear justification:
 1. **"No state beyond `LineType` code-block tracker."** Tables inherently need multi-line state (buffer rows until block ends). Contained to a single `Option<TableState>` field on `MarkdownRender`. No other state added.
 2. **"Only `src/render/markdown.rs` changes."** Tables need an end-of-stream flush hook, which means 3 small callsite changes: `stream.rs` (streaming), `app_config.rs::print_markdown` (one-shot CLI), `session.rs::render` (session display). Each change is a single line: `output.push_str(&render.finalize())`.
 These are necessary complexity, not scope creep. The plan explicitly recognizes them.
 ## Resolved Design Decisions
 1. **Library:** use `comfy-table 7.2.2` with `custom_styling` feature enabled. Only Rust table library that correctly strips ANSI escapes before width computation (via `s.ansi_strip().width()` at `custom_styling.rs:10`). Alternatives (tabled, cli-table, term-table, prettytable-rs) either lack ANSI support, don't support arbitrary border colors, or are abandoned. Full survey in the librarian report.
 2. **Streaming behavior:** silent accumulation. Table rows return empty string from renderer; buffered internally; rendered on block end. Matches glamour.
 3. **Detection lookahead:** speculative table detection. First `|...|` line buffered as `PendingHeader`; next line's shape confirms (separator → commit to table) or rejects (anything else → flush both as paragraphs). Required for correctness — GFM demands separator row.
 4. **Border color:** new `MarkdownStyles::table_border` field resolved from theme via scope `punctuation.definition.table.markdown` → fallback `punctuation` → fallback `hrule` (which already exists). Applies to all box-drawing chars uniformly.
 5. **Header styling:** reuse existing `heading` style (bold + heading color) for header cells. No new field needed.
 6. **Alignment specifiers:** parse `:---`, `---:`, `:---:` from separator row; map to `comfy_table::CellAlignment::Left/Right/Center`. Default (no colons) = left.
 7. **Inline markdown in cells:** run `apply_inline()` on each cell before feeding to comfy-table. `custom_styling` feature ensures widths compute correctly on pre-styled text.
 ## Architecture
 ### New dependency
 `Cargo.toml`:
 ```toml
 comfy-table = { version = "7.2.2", features = ["custom_styling"] }
 ```
 Pulls in `unicode-width` (already used indirectly), `unicode-segmentation`, and `ansi-str`. Total footprint small (~77KB crate).
 ### New MarkdownStyles field
 `markdown.rs:612` — add one line to the struct:
 ```rust
 pub struct MarkdownStyles {
    // ... existing 11 fields ...
    table_border: Color,
 }
 ```
 Resolved in `from_theme()` via `resolve_scope_style(theme, "punctuation.definition.table.markdown", &["punctuation", "meta.separator"], truecolor)`. Falls back to `hrule` color if scope not found. `None` case → default color.
 ### New LineKind variant
 `markdown.rs:57` — extend enum:
 ```rust
 pub enum LineKind {
    // ... existing variants ...
    TableRow,       // any line matching ^\s*\|.*\|\s*$
    TableSeparator, // subset of TableRow matching ^\s*\|(\s*:?-+:?\s*\|)+\s*$
 }
 ```
 Two variants because separator detection needs its own regex; keeping them distinct simplifies the state machine.
 ### Table detection regexes
 Add to the `LazyLock` regex block:
 ```rust
 // A line that looks like a table row: starts and ends with |, non-empty content
 static TABLE_ROW: LazyLock<Regex> = LazyLock::new(|| Regex::new(r"^\s*\|.*\|\s*$").unwrap());
 // The separator row that must follow a header: | :---: | ---: | :--- | ---- |
 static TABLE_SEPARATOR: LazyLock<Regex> = LazyLock::new(|| Regex::new(
    r"^\s*\|(\s*:?-{3,}:?\s*\|)+\s*$"
 ).unwrap());
 ```
 Order in `detect_line_kind`: check `TABLE_SEPARATOR` before `TABLE_ROW` (separator is a subset of row).
 ### New TableState struct
 Added to `markdown.rs`:
 ```rust
 enum TableState {
    /// Just saw a `|...|` line but haven't seen the separator yet.
    /// If next line is a separator → transition to Active.
    /// If next line is anything else → not a table; flush the header as paragraph + process next line.
    PendingHeader(String),
    /// Confirmed table. Accumulating data rows.
    Active {
        header: Vec<String>,
        alignments: Vec<CellAlignment>,
        rows: Vec<Vec<String>>,
    },
 }
 ```
 ### MarkdownRender state field
 `markdown.rs:266` — add one field:
 ```rust
 pub struct MarkdownRender {
    // ... existing 8 fields ...
    table_state: Option<TableState>,
 }
 ```
 Initialized to `None` in `init()`.
 ### State machine (in `render_line_mut`)
 Runs BEFORE the existing branch on `is_code`/`raw_markdown`/rich:
 ```rust
 fn render_line_mut(&mut self, line: &str) -> String {
    let (line_type, line_kind, code_syntax, is_code) = self.check_line(line);
    self.prev_line_type = line_type;
    self.code_syntax = code_syntax;
    // Table state machine — runs FIRST because tables preempt normal rendering
    if let Some(output) = self.handle_table_state(line, line_kind) {
        return output;
    }
    // ... existing code / raw_markdown / rich branch (unchanged) ...
 }
 fn handle_table_state(&mut self, line: &str, kind: LineKind) -> Option<String> {
    match (&mut self.table_state, kind) {
        // No pending table + saw a row → start pending
        (None, LineKind::TableRow) => {
            self.table_state = Some(TableState::PendingHeader(line.to_string()));
            Some(String::new())  // silent accumulation
        }
        // No pending table + saw a separator (rare) → treat as paragraph
        (None, LineKind::TableSeparator) => None,
        // Pending header + saw separator → commit to Active
        (Some(TableState::PendingHeader(header_line)), LineKind::TableSeparator) => {
            let header = parse_table_row(&header_line);
            let alignments = parse_alignments(line);
            self.table_state = Some(TableState::Active { header, alignments, rows: vec![] });
            Some(String::new())
        }
        // Pending header + saw another row (no separator) → not a table; flush both as paragraphs
        (Some(TableState::PendingHeader(header_line)), LineKind::TableRow) => {
            let flushed = std::mem::take(header_line).clone();
            self.table_state = None;
            let a = self.render_as_paragraph(&flushed);
            let b = self.render_as_paragraph(line);
            Some(format!("{a}\n{b}"))
        }
        // Pending header + saw anything else → not a table; flush header + process line normally
        (Some(TableState::PendingHeader(_)), _) => {
            let TableState::PendingHeader(header_line) = self.table_state.take().unwrap()
                else { unreachable!() };
            let flushed = self.render_as_paragraph(&header_line);
            None  // caller continues with normal rendering; prepend `flushed` in caller
            // (implementation detail: needs to return Some(flushed + normal_render) — see impl)
        }
        // Active + saw a row → add to buffer
        (Some(TableState::Active { rows, .. }), LineKind::TableRow) => {
            rows.push(parse_table_row(line));
            Some(String::new())
        }
        // Active + saw anything else → flush table + process line
        (Some(TableState::Active { .. }), _) => {
            let TableState::Active { header, alignments, rows } = self.table_state.take().unwrap()
                else { unreachable!() };
            let rendered = self.render_table(header, alignments, rows);
            None  // caller prepends rendered + processes line normally
            // (same pattern as above)
        }
        (None, _) => None,  // no table state to affect; normal rendering
    }
 }
 ```
 **Note on the "prepend + continue" pattern**: for the flush-then-continue transitions, the cleanest implementation splits into `handle_table_state` returning `Option<String>` for the flushed-table portion, and the caller concatenates that with the normally-rendered current line. Implementation detail; the state transitions are what matter for design review.
 ### Cell parsing
 Two helpers:
 ```rust
 fn parse_table_row(line: &str) -> Vec<String> {
    // Strip leading/trailing whitespace and the outer `|`
    let inner = line.trim().trim_start_matches('|').trim_end_matches('|');
    inner.split('|').map(|c| c.trim().to_string()).collect()
 }
 fn parse_alignments(separator_row: &str) -> Vec<CellAlignment> {
    let cells = parse_table_row(separator_row);
    cells.iter().map(|c| {
        let trimmed = c.trim();
        let starts = trimmed.starts_with(':');
        let ends = trimmed.ends_with(':');
        match (starts, ends) {
            (true, true) => CellAlignment::Center,
            (false, true) => CellAlignment::Right,
            _ => CellAlignment::Left,
        }
    }).collect()
 }
 ```
 Edge cases:
 - Empty cells (`| | |`) → empty strings in the returned Vec, comfy-table handles.
 - Column count mismatch (header has 3 cells, data row has 2) → comfy-table's behavior: pads or truncates. Test coverage will verify.
 - Escaped pipes (`\|`) in cell content — GFM spec supports; **defer to Phase 2.1 follow-up if needed**. Initial implementation splits on raw `|`.
 ### Table rendering
 ```rust
 use comfy_table::{Table, CellAlignment, presets::UTF8_FULL, ContentArrangement};
 fn render_table(
    &self,
    header: Vec<String>,
    alignments: Vec<CellAlignment>,
    rows: Vec<Vec<String>>,
 ) -> String {
    let mut table = Table::new();
    table.load_preset(UTF8_FULL);
    table.set_content_arrangement(ContentArrangement::Dynamic);
    if let Some(width) = self.wrap_width {
        table.set_width(width);
    }
    // Header cells: inline-rendered + heading style (bold + heading color)
    let styled_header: Vec<String> = header.iter()
        .map(|c| apply_bold(&apply_inline(c, &self.styles), self.styles.heading.0))
        .collect();
    table.set_header(styled_header);
    // Per-column alignment
    for (i, align) in alignments.iter().enumerate() {
        if let Some(col) = table.column_mut(i) {
            col.set_cell_alignment(*align);
        }
    }
    // Data rows: inline-rendered only
    for row in rows {
        let styled_row: Vec<String> = row.iter()
            .map(|c| apply_inline(c, &self.styles))
            .collect();
        table.add_row(styled_row);
    }
    // Border color: apply table_border to all box-drawing chars via ANSI wrapping.
    // comfy-table's styling API — inspect final rendered output and colorize border chars,
    // OR use comfy-table's built-in styling if it supports per-component color.
    // Investigate during Phase 2.4 implementation.
    format!("{table}")
 }
 ```
 **Border color note**: comfy-table has border styling but it may not expose direct per-char color control. Two options:
 1. Post-process the rendered string with a regex that colorizes box-drawing chars (`[─│┼┌┐└┘├┤┬┴]`).
 2. Use comfy-table's `style()` API if it supports arbitrary ANSI.
 Confirm during Phase 2.4 implementation — worst case is regex post-process, which is simple.
 ### `render_line` (immutable) behavior for partial table rows
 `render_line` is called on the incomplete in-progress line during streaming. If the partial buffer looks like `| foo | ba`, it's mid-row and immutable — can't add to state.
 Behavior: `render_line` sees `LineKind::TableRow` or the pattern and just renders raw markdown (since it can't buffer). The user sees `| foo | ba` briefly, then it disappears when the complete row arrives via `render_line_mut` (silent accumulation) and eventually the rendered table appears. Consistent with the "silent accumulation" decision.
 ### Line wrapping with hanging indent
 Phase 1's `render_bullet`/`render_numbered`/`render_task`/`render_blockquote` produce a single line each and don't wrap long content. When `wrap_width` is set, long items overflow past the wrap column. This phase fixes that by adding **hanging-indent wrapping** using `textwrap` (already a dependency).
 **Desired output:**
 ```
 • text that
  wraps and
  wraps
 1. text that
   wraps and
   wraps
 [ ] task text
    that wraps
 │ blockquote line
 │ that continues
 ```
 **Design:**
 Each block renderer computes a prefix width, applies wrapping to the content with `textwrap::Options::subsequent_indent(prefix_width_spaces)`, then styles each wrapped line with the appropriate prefix on line 1 and continuation-indent on later lines.
 Critical subtlety: `textwrap` computes width by **byte length**, not visual width. We must wrap the **plain text content** (before applying inline ANSI codes), then apply `apply_inline` per wrapped line. Otherwise ANSI escape bytes distort the wrap column calculation.
 Sketch:
 ```rust
 fn render_bullet(&self, line: &str) -> String {
    let (leading, content) = split_leading_indent(line);  // handles nested lists
    let content_after_marker = &content[content.find(' ').unwrap() + 1..];  // strip "- "
    let Some(wrap_width) = self.wrap_width else {
        // No wrap → single line (current Phase 1 behavior)
        return format!("{leading}{bullet}{}", apply_inline(content_after_marker, &self.styles));
    };
    let bullet_visible = "• ";  // 2 columns
    let subseq_indent = "  ";   // 2 spaces to align under text
    let effective_width = (wrap_width as usize).saturating_sub(leading.len() + bullet_visible.len());
    let wrapped = textwrap::wrap(content_after_marker, textwrap::Options::new(effective_width));
    let styled_bullet = ansi_wrap(bullet_visible, self.styles.list_bullet);
    let mut out = String::new();
    for (i, wline) in wrapped.iter().enumerate() {
        if i == 0 {
            out.push_str(&format!("{leading}{styled_bullet}{}", apply_inline(wline, &self.styles)));
        } else {
            out.push_str(&format!("\n{leading}{subseq_indent}{}", apply_inline(wline, &self.styles)));
        }
    }
    out
 }
 ```
 Same pattern for `render_numbered` (subsequent indent width = digits + `. ` = variable), `render_task` (subsequent indent = 4 spaces for `[ ] `), and `render_blockquote` (subsequent indent = styled `│ ` prefix, same styling as first line).
 **Interaction with existing `wrap_line`:** The current `wrap_line` (markdown.rs:192-198) is used for code lines and paragraphs. It sets `initial_indent` but not `subsequent_indent`, so paragraphs already wrap without hanging indent — that's correct (paragraphs should wrap flush-left). Only list/blockquote block renderers need the new hanging-indent path; leave `wrap_line` alone.
 **Nested lists:** the existing `leading` whitespace preservation from Phase 1 continues to work — subsequent-indent gets prepended AFTER the leading, so a nested list item wraps correctly under its own bullet.
 **Headings:** intentionally NOT wrapped with hanging indent. If a heading is longer than wrap width, it wraps flush-left (via existing `wrap_line`). Headings are usually short; hanging indent under `##` would look odd.
 **`wrap_width = None`:** all renderers skip wrapping entirely and emit a single line, matching current Phase 1 behavior. Users who want wrapping set the `wrap: auto` config.
 ### `finalize()` method
 New method on `MarkdownRender`:
 ```rust
 pub fn finalize(&mut self) -> String {
    match self.table_state.take() {
        None => String::new(),
        Some(TableState::PendingHeader(line)) => self.render_as_paragraph(&line),
        Some(TableState::Active { header, alignments, rows }) => {
            self.render_table(header, alignments, rows)
        }
    }
 }
 ```
 Called by:
 1. **`stream.rs`** at `SseEvent::Done` — before `break 'outer`, emit `render.finalize()` output.
 2. **`app_config.rs::print_markdown`** — after `markdown_render.render(text)`, append `finalize()` output.
 3. **`session.rs::Session::render`** — after `render.render(text)`, append `finalize()` output.
 Each is a single-line addition.

 - [x] Test: wide chars / emoji in cells
 **Commit:** `feat(render): render markdown tables with comfy-table`
 ### Phase 2.5 — State machine + finalize

 - [x] Test: `|...|` line NOT followed by separator → both flushed as paragraphs
 - [x] Test: multiple tables in one input
 - [x] Test: `render_line` on partial `| foo | ba` (immutable) → raw text (no state mutation)
 **Commit:** `feat(render): wire table state machine and finalize hook`
 ### Phase 2.6 — Hanging-indent line wrapping for lists and blockquotes
 - [x] Add `wrap_with_hanging_indent(content, prefix_width, wrap_width) -> Vec<String>` helper (uses `textwrap` on plain content, callers apply inline styling per line)
 - [x] Refactor `render_bullet` to compute prefix width (`• ` = 2), wrap, apply inline per line, prepend styled bullet + subsequent 2-space indent
 - [x] Refactor `render_numbered` to compute prefix width from digit count + `. `, wrap, apply inline per line, prepend styled number + subsequent variable-width indent
 - [x] Refactor `render_task` to compute prefix width (`[ ] ` = 4), wrap, apply inline per line, prepend styled checkbox + subsequent 4-space indent
 - [x] Refactor `render_blockquote` to wrap, apply inline per line, prepend styled `│ ` on every line (both initial and subsequent)
 - [x] `wrap_width = None` path: skip wrapping, emit single line (matches Phase 1)
 - [x] Preserve leading whitespace (nested list indent) — subseq indent goes AFTER leading
 - [x] Test: bullet with content wider than wrap_width → hanging indent under text
 - [x] Test: numbered list with 2+ digit numbers (`10. `, `100. `) → subseq indent matches digit width
 - [x] Test: task item wraps with 4-space subseq indent
 - [x] Test: blockquote wraps with `│ ` continuation prefix (styled same as first line)
 - [x] Test: nested bullet (`  - inner text that wraps`) → nested indent + hanging indent both applied
 - [x] Test: content with inline markdown that wraps mid-span — wrap boundary respects word breaks, not ANSI escapes
 - [x] Test: `wrap_width = None` → no wrapping (single line, current behavior)
 **Commit:** `feat(render): hanging-indent line wrapping for lists and blockquotes`
 ### Phase 2.7 — Integration + edge cases
 - [x] Test: markdown with mixed content (paragraphs + headings + tables + lists)
 - [x] Test: `raw_markdown: true` bypasses table rendering (renders as raw pipe rows via syntect grammar)
 - [x] Test: `theme.is_none()` → tables still render (uncolored) via comfy-table
 - [x] Test: user's custom theme colors apply to borders
 - [x] Test: column count mismatch (header has 3, row has 2) — verify comfy-table behavior; document expected output
 - [ ] Manual REPL test: stream a response with tables, verify silent accumulation → rendered flush *(deferred — requires interactive terminal)*
 - [ ] Manual REPL test: `.set raw_markdown true` reverts tables to raw *(deferred — requires interactive terminal)*
 - [x] Update `.sisyphus/plans/rich-markdown-renderer.md` progress log noting Phase 2 completion + commit SHA
 - [x] `cargo check` clean
 - [x] `cargo test` all pass
 **Commit:** `test(render): comprehensive table rendering coverage`
 ## Success Criteria (Phase 2)
 - [ ] Standard GFM tables render with box-drawing chars
 - [ ] Alignment specifiers (`:---`, `---:`, `:---:`) respected
 - [ ] Inline markdown inside cells (`**bold**`, code, links) renders correctly
 - [ ] Wide chars / emoji don't misalign columns (comfy-table's `ansi_strip().width()` verified working)
 - [ ] Border color from user's syntect theme
 - [ ] Header row is bold + heading color
 - [ ] Silent accumulation during streaming (no flashing raw→rendered transitions)

 ## Progress Log
 Append-only. One entry per commit or session.
 ### 2026-07-22 — Planning complete
 - Verified post-Phase-1 state via explore agent (MarkdownRender struct, LineKind enum, apply_inline pipeline, streaming buffer mechanics)
 - Surveyed Rust table libraries via librarian agent → chose `comfy-table 7.2.2` (only lib with correct ANSI-in-cells width handling + active maintenance + arbitrary border colors)
 - Resolved 7 design decisions (library, streaming behavior, detection lookahead, border color, header styling, alignment parsing, cell inline rendering)
 - Acknowledged 2 justified deviations from Phase 1 principles (multi-line state, 3 small callsite changes for finalize hook)
 - Added Phase 2.6 (hanging-indent wrapping for lists and blockquotes) — user-requested addition; touches Phase 1 block renderers (render_bullet/render_numbered/render_task/render_blockquote) but reuses existing `textwrap` dep. Tables get wrapping for free via `comfy-table`'s `ContentArrangement::Dynamic`.
 - Wrote this plan file
 - Next: hand to Momus for review before starting Phase 2.1
 ### 2026-07-22 — Phase 2.1 complete (commit `fcc4a1d`)
 - Added `comfy-table 7.2.2` with `custom_styling` feature to `Cargo.toml`; slotted alphabetically between `clap` and `dirs`.
 - Added `table_border: Color` field to `MarkdownStyles`; resolved in `from_theme` via `punctuation.definition.table.markdown` → `punctuation` → `meta.separator` fallback chain; `none()` sets `Color::Reset`.
 - Extended the three existing `MarkdownStyles` tests with `table_border` assertions (dark theme resolves ≠ Reset, minimal-root-scope theme falls back to `punctuation` color `rgb(0x77, 0x77, 0x77)`, no-theme → `Color::Reset`).
 - Marked field `#[allow(dead_code)]` — will be removed in Phase 2.4 when `render_table` consumes it.
 - `cargo check` clean, `cargo test` all 1207 pass.
 ### 2026-07-22 — Phase 2.2 complete (commit `7671d28`)
 - Added `TABLE_ROW_RE` and `TABLE_SEPARATOR_RE` regexes. Separator uses `-+` (one or more dashes) instead of the plan's `{3,}` to accept the plan's own test case `|:--|--:|:-:|`; GFM spec doesn't mandate a minimum, so more lenient is safer.
 - Added `TableRow` / `TableSeparator` variants to `LineKind`; extended `detect_line_kind` (separator checked before row).
 - `render_markdown_line` handles both variants as `apply_inline` (paragraph-equivalent) — they'll be intercepted by the state machine in Phase 2.5 before reaching this fallback.
 - 4 new tests covering row, separator (three alignment shapes), non-table pipes in prose, and separator-vs-row precedence.
 ### 2026-07-22 — Phase 2.3 complete (commit `c062f34`)
 - Added `parse_table_row(line)` and `parse_alignments(separator_row)` free functions.
 - Imported `comfy_table::CellAlignment` at module level (also used in Phase 2.4).
 - Both functions marked `#[allow(dead_code)]` — consumed by state machine in Phase 2.5.
 - 6 tests: cell splitting, empty cells, whitespace trimming, colon-based alignment mapping (long dashes, short dashes, default-to-left).
 ### 2026-07-22 — Phase 2.4 complete (commit `cdfaa0f`)
 - Added `TableState` enum (`PendingHeader(String)` / `Active { header, alignments, rows }`) and `table_state: Option<TableState>` field on `MarkdownRender`.
 - Implemented `MarkdownRender::render_table` using `comfy-table`'s `UTF8_FULL` preset + `ContentArrangement::Dynamic`; sets `wrap_width` on the table when present; per-column alignment via `column_mut(i).set_cell_alignment`.
 - Header cells: `apply_inline` then wrapped in `.with(heading_color).bold()`. Data cells: `apply_inline` only.
 - Border coloring: `colorize_box_chars` helper post-processes the rendered string. It extracts SGR prefix/suffix from a probe styled character, walks the input once, and wraps consecutive box-drawing runs (`\u{2500}..=\u{257F}`) with the SGR pair.
 - `#[allow(dead_code)]` on `TableState`, `table_state`, `render_table`, `colorize_box_chars`, and (re-added) `table_border` — cleared in Phase 2.5 once the state machine wires everything in.
 - 8 new tests: border colorization (with/without borders), header bold, inline markdown in cells, alignment specifiers, wide chars/emoji, border color at output start, plus a 3x3 default-alignment sanity test.
 ### 2026-07-22 — Phase 2.5 complete (commit `bf06d5e`)
 - Added `TableAction` enum (`Consumed(String)` / `FlushAndContinue(String)` / `Passthrough`) — replaces the plan's ambiguous `Option<String>` return with an explicit three-way decision.
 - Implemented `MarkdownRender::handle_table_state` covering all 7 transitions from the state diagram (including code-block entry as an implicit flush trigger).
 - Implemented `MarkdownRender::render_as_paragraph` helper for false-positive header flushes.
 - Implemented `pub fn finalize(&mut self) -> String`.
 - `render_line_mut` runs the state machine before the code/raw/rich dispatch. `raw_markdown: true` bypasses the state machine entirely (raw mode preserves user-supplied markdown untouched). Code block entry (`is_code`) maps to `LineKind::Paragraph` for state-machine purposes, forcing a flush.
 - Wired `finalize()` into three call sites:
  - `src/render/stream.rs` at `SseEvent::Done` — queues a trailing newline + flushed output via crossterm `queue!/style::Print` before break.
  - `src/config/app_config.rs::print_markdown` — appends flush output before `println!`.
  - `src/config/session.rs::Session::render` — flushes after both System and Assistant message rendering (per-message finalize prevents cross-message state bleed).
 - Dropped `#[allow(dead_code)]` from `TableState`, `table_state`, `render_table`, `colorize_box_chars`, `parse_table_row`, `parse_alignments`, and `table_border` — all now live in the binary.
 - 9 new tests: full-table streaming, deferred silent accumulation, `finalize` for active/pending/empty state, `|...|`-without-separator flush, multiple tables in one input, `render_line` immutability, raw-mode bypass.
 ### 2026-07-22 — Phase 2.6 complete (commit `d790782`)
 - Added `wrap_plain_content(content, effective_width) -> Vec<String>` helper (thin `textwrap::wrap` wrapper that clamps width to ≥1).
 - Added `kind_pre_wraps(kind) -> bool` helper (returns true for bullet/numbered/task/blockquote).
 - Threaded `wrap_width: Option<u16>` through `render_markdown_line` and all four block renderers.
  - `wrap_width = None` short-circuits back to Phase 1 single-line behavior.
  - `wrap_width = Some(w)` wraps plain content (pre-inline-styling) at `w - (leading + prefix_width)`, then applies `apply_inline` per wrapped chunk.
 - Prefix widths: `render_bullet` = 2 (`• `), `render_task` = 4 (`[ ] `), `render_numbered` = digit_count + 2 (`. `), `render_blockquote` = 2 (`│ `).
 - `render_blockquote` prepends the styled `│ ` on **every** wrapped line (not just the first); the other three prepend the marker on line 1 and a spaces-only subsequent indent on continuation lines.
 - Leading whitespace (nested-list indent) is emitted BEFORE the prefix on every wrapped line, preserving nested-list appearance.
 - `render_rich_markdown_line` skips `wrap_line` when `kind_pre_wraps(kind)` is true, avoiding a second unwanted wrap pass over already-styled content.
 - Updated all 17 existing test call sites of `render_markdown_line` (via ast-grep) to pass `None` — Phase 1 behavior preserved end-to-end.
 - 8 new tests: bullet 2-space indent, numbered 4-space (`42. `) and 5-space (`100. `) indent, task 4-space indent, blockquote pipe-on-every-line, nested-bullet leading indent, `None` single-line short-circuit, inline markdown intact after wrap.
 ### 2026-07-22 — Phase 2.7 complete (commit `e82e5ab`)
 - 4 integration/edge-case tests: mixed-content document (heading + paragraph + list + blockquote + table + trailing prose), table renders without theme, table borders pick up custom theme color, column-count mismatch tolerated by comfy-table.
 - Full test suite: 1246 pass, 0 fail. `cargo check` clean.
 - Manual REPL verification deferred (requires interactive terminal); test coverage validates rendering pipeline end-to-end.
 - Phase 2 complete.

 # Rich Markdown Renderer for the REPL
 **Status:** Planning complete, awaiting Momus review before implementation.
 **Owner:** Coyote maintainer
 **Estimated effort:** Phase 1 = 4-5 days, Phase 2 (tables) = +1-2 days
 **Related flag:** `raw_markdown` (already plumbed; see commit history for the plumbing PR)
 ---
 ## Goal
 Replace Coyote's current syntect-only markdown rendering with a rich renderer that transforms markdown syntax into styled terminal output (headings become colored + bold text, `**bold**` becomes actual bold, backticks strip and stylize, blockquotes get a `│` prefix, etc.), matching glamour's structural output while preserving the user's existing syntect `.tmTheme` colors.
 The current renderer just applies syntect's markdown grammar for syntax highlighting — the markdown syntax characters (`#`, `**`, `` ` ``) stay in the output, just colored. Users get raw markdown with color, not rendered markdown. The new renderer actually transforms the markdown into styled output like glamour (github.com/charmbracelet/glamour) does.
 ## Non-Goals
 - **Not replacing the renderer's public API.** `MarkdownRender::init`, `render`, `render_line`, and `RenderOptions` all keep their existing signatures. Callers (`stream.rs`, `session.rs`, `app_config.rs::print_markdown`, `request_context.rs::session_info`) do not change.
 - **Not changing streaming architecture.** `stream.rs` still calls `render()` on complete lines and `render_line()` on the incomplete tail. New renderer must fit this line-by-line contract.
 - **Not touching code block rendering.** Fenced code blocks (` ```lang ... ``` `) continue to route to syntect language-specific highlighting via `find_syntax_by_token`. The new renderer only affects markdown syntax rendering, never code content.
 - **Not adding new dependencies.** All work uses existing `syntect`, `fancy-regex`, `crossterm`, `textwrap`.
 - **Not shipping tables in Phase 1.** Tables require multi-line buffering, which conflicts with the stateless streaming model. Table rows render as raw `| col | col |` until Phase 2.
 - **Not implementing OSC 8 hyperlink fallback logic.** Emit OSC 8 codes unconditionally + always show URL visibly. Terminals that don't support OSC 8 strip the codes and see plain "text URL" text.
 ## Design Principles
 1. **Colors from user theme, layout from glamour.** Every construct extracts its color from the user's syntect theme via scope lookup with fallback chains. The structural layout (prefixes, indents, borders, box-drawing) matches glamour's default dark style.
 2. **`raw_markdown: true` = current behavior byte-identical.** The existing syntect-on-markdown-grammar path is preserved as the "raw" branch and reachable via config/CLI/REPL. Zero regression risk for users who want the old behavior.
 3. **Preserve line-by-line rendering.** No state beyond the existing `LineType` code-block tracker. Stateless per-line rendering means the streaming's `render_line` for partial buffer works identically to the mutating `render_line_mut` for complete lines.
 4. **Regex-based inline parsing, not pulldown-cmark.** A full markdown parser needs the complete document to disambiguate. Regexes match balanced spans and gracefully leave unclosed spans as raw text — exactly right for streaming's mid-token partial-line rendering.
 5. **Only `src/render/markdown.rs` changes.** Scope containment: the entire implementation lives in one file. No touches to `stream.rs`, `mod.rs`, `session.rs`, `app_config.rs`, `request_context.rs`.
 ## Resolved Design Decisions
 Recorded here so future sessions don't re-litigate them:
 1. **Tables:** deferred to Phase 2. Phase 1 leaves table rows as raw markdown.
 2. **H2-H6 hash prefixes:** matched to glamour — keep `##`, `###`, `####`, `#####`, `######` visible in the heading color as a level indicator. H1 gets padded ` text ` treatment.
 3. **Link rendering:** OSC 8 hyperlink codes wrapping visible `{text} {url}` — modern terminals show a clickable link, older terminals show plain styled text. Matches glamour exactly. Users on broken terminals can fall back to `.set raw_markdown true`.
 ## Architecture
 ### Data structures (added to `MarkdownRender`)
 ```rust
 struct MarkdownStyles {
    heading: (Color, bool /* force_bold */),
    bold: Color,
    italic: Color,
    inline_code_fg: Color,
    inline_code_bg: Option<Color>,
    blockquote: Color,
    list_bullet: Color,
    link_text: Color,
    link_url: Color,
    strikethrough: Color,
    hrule: Color,
 }
 ```
 Populated once in `MarkdownRender::init` via a new `resolve_scope_style(theme, primary_scope, fallbacks)` helper that generalizes the existing `get_code_color()` pattern (markdown.rs:299).
 When `options.theme.is_none()`, all styles collapse to defaults (raw text output with no colors — matches current behavior).
 ### Line-type detection
 Extended `check_line` returns a new `LineKind` enum (only for non-code lines):
 | Regex | LineKind |
 |---|---|
 | `^\s*(#{1,6}) +.+` | Heading(level) |
 | `^\s*> ?.*` | Blockquote |
 | `^(\s*)- \[[ xX]\] +.+` | TaskItem(checked) |
 | `^(\s*)[-*+] +.+` | BulletItem |
 | `^(\s*)\d+\. +.+` | NumberedItem |
 | `^\s*(-{3,}|_{3,}|\*{3,})\s*$` | HorizontalRule |
 | `^\s*\|.*\|\s*$` | (Phase 2: TableRow) — treated as paragraph for now |
 | default | Paragraph |
 **Stateless:** line-type detection carries no state beyond the existing `prev_line_type`/`code_syntax` fields for code block tracking. Streaming's partial-line `render_line` works identically to complete-line `render_line_mut`.
 ### Block-level rendering
 Each `LineKind` triggers a block transformation that strips syntax markers and applies structural styling. All block types then run their remaining text content through the inline pipeline.
 | LineKind | Transformation |
 |---|---|
 | `Heading(1)` | Prefix ` `, suffix ` ` (single spaces), apply bold + heading color to entire line |
 | `Heading(2..=6)` | Keep visible `##`/`###`/etc. prefix, apply bold + heading color |
 | `Blockquote` | Replace `> ` with `│ ` (styled blockquote color); apply blockquote color to remaining content |
 | `BulletItem` | Replace `-`/`*`/`+` with `•` (styled list_bullet color); preserve leading whitespace for nesting |
 | `NumberedItem` | Preserve number, style the `.` in list_bullet color |
 | `TaskItem(false)` | Replace `[ ]` with `[ ]` styled in list_bullet color |
 | `TaskItem(true)` | Replace `[x]` with `[✓]` styled |
 | `HorizontalRule` | Emit `────────` (8-char box-drawing) styled with hrule color (typically dim/gray) |
 | `Paragraph` | No block transform, inline pass only |
 ### Inline rendering (regex pipeline, applied in order)
 Order matters — inline code first prevents re-parsing code content as bold/italic:
 1. **Inline code** (`` `text` ``) — regex `` `([^`\n]+)` ``, strip backticks, apply `inline_code_fg` + optional `inline_code_bg`.
 2. **Images** (`![alt](url)`) — regex `!\[([^\]]*)\]\(([^)]+)\)`, emit `Image: {alt} → {url}` styled with `link_url`. Wrap in OSC 8 hyperlink codes.
 3. **Links** (`[text](url)`) — regex `\[([^\]]+)\]\(([^)]+)\)`, emit `{text} {url}` with `link_text` on the label and `link_url` on the URL. Wrap in OSC 8 hyperlink codes.
 4. **Bold** (`**text**` or `__text__`) — regex `\*\*([^*\n]+)\*\*` and `__([^_\n]+)__`, strip markers, apply bold ANSI + `bold` color.
 5. **Italic** (`*text*` or `_text_`) — regex `(?<![*\w])\*([^*\n]+)\*(?!\*)` and `(?<![_\w])_([^_\n]+)_(?!_)` — lookbehind/lookahead prevents word-internal `_` from matching (e.g., `some_var_name`). `fancy-regex` supports lookbehind.
 6. **Strikethrough** (`~~text~~`) — regex `~~([^~\n]+)~~`, strip markers, apply ANSI strikethrough (`\x1b[9m`).
 **Partial-span handling for streaming:** regexes only match balanced spans. Unclosed spans (`**bold` with no closing) stay raw. When the closing marker arrives on the next token, the complete-line pass renders the full span correctly.
 ### OSC 8 hyperlinks
 ```
 \x1b]8;;{url}\x1b\\{visible_text}\x1b]8;;\x1b\\
 ```
 Emit unconditionally around links and images. Unsupported terminals strip the codes and see plain visible text. Zero degradation.
 ### Branching in `highlight_line`
 ```rust
 fn highlight_line(&self, line: &str, syntax: &SyntaxReference, is_code: bool) -> String {
    if is_code {
        // unchanged — code block content via language-specific syntect
        self.highlight_code_syntect(line, syntax)
    } else if self.options.raw_markdown {
        // preserved current behavior: syntect on markdown grammar
        self.highlight_markdown_syntect(line, &self.md_syntax)
    } else {
        // new rich rendering path
        self.render_markdown_line(line)
    }
 }
 ```
 Code blocks route to syntect regardless of `raw_markdown` — the flag only affects markdown syntax rendering.
 ## Consumers Verified
 Complete map of `MarkdownRender` consumers (from explore agent research). All continue to work without modification because the public API is unchanged:
 1. `src/render/mod.rs:16-33` — `render_stream()` (streaming path via `markdown_stream()`)
 2. `src/render/stream.rs:67-171` — `markdown_stream_inner()` calls `render.render(head)` and `render.render_line(&buffer)`
 3. `src/config/app_config.rs:420-429` — `print_markdown()` (CLI one-shot)
 4. `src/config/request_context.rs:1706-1723` — `session_info()` (`.info` REPL command)
 5. `src/config/session.rs:278-396` — `Session::render()` (per assistant message)
 6. `src/render/markdown.rs:311-397` — existing tests
 ## Phase 1 Implementation
 ### Phase 1.1 — Scope lookup helper + precomputed styles
 - [x] Add `resolve_scope_style(theme, primary, fallbacks)` helper (generalizes `get_code_color()`)
 - [x] Add `MarkdownStyles` struct + populate in `MarkdownRender::init` for all 10 constructs
 - [x] Handle `theme.is_none()` gracefully (all styles = defaults)
 - [x] Test: verify each style resolves correctly with the built-in dark theme
 - [x] Test: verify each style falls back correctly with a minimal theme that only defines root scopes
 **Commit:** `feat(render): precompute markdown scope styles for rich rendering`
 ### Phase 1.2 — Line-type detection
 - [x] Add `LineKind` enum + `detect_line_kind()` function
 - [x] Wire into `check_line` — return `LineKind` alongside existing `LineType`
 - [x] Test each pattern in isolation (heading, blockquote, bullets, numbered, task, hrule, paragraph)
 - [x] Test edge cases: `## ` vs `##text` (no space, not a heading), indented list items, empty blockquote
 **Commit:** `feat(render): detect markdown block-level line types`
 ### Phase 1.3 — Inline rendering pipeline
 - [x] Add regex constants (LazyLock) for each inline construct
 - [x] Add `apply_inline(text: &str, styles: &MarkdownStyles) -> String` that runs the pipeline in order
 - [x] Test each construct in isolation
 - [x] Test order-dependence: `**foo `bar` baz**` — bold wraps inline code correctly
 - [x] Test partial spans stay raw: `**unclosed` → `**unclosed`
 - [x] Test italic doesn't false-positive: `some_var_name`, `a * b * c` (math-like expression)
 - [x] Test OSC 8 emission for links and images
 **Commit:** `feat(render): rich inline markdown rendering (bold, italic, code, links)`
 ### Phase 1.4 — Block-level rendering
 - [x] Add `render_markdown_line(line)` that dispatches on `LineKind`
 - [x] Implement each block transform (heading, blockquote, bullet, numbered, task, hrule, paragraph)
 - [x] After block transform, always run `apply_inline` on the content
 - [x] Test each block type with inline styling nested inside (bold in heading, code in list item, link in blockquote)
 **Commit:** `feat(render): rich block-level markdown rendering (headings, quotes, lists, hr)`
 ### Phase 1.5 — Wire into `highlight_line` with `raw_markdown` branch
 - [x] Refactor `highlight_line` to branch on `options.raw_markdown`
 - [x] Remove `#[allow(dead_code)]` from `RenderOptions::raw_markdown`
 - [x] Verify all existing tests pass with `raw_markdown: true` (byte-identical output)
 - [ ] Manual REPL test: send a message with a mix of constructs, verify output matches expectations
 - [ ] Manual streaming test: verify no flashing, partial spans render smoothly
 **Commit:** `feat(render): activate rich markdown renderer as default`
 ### Phase 1.6 — Test coverage
 - [x] Heading levels 1-6 (transforms + styling)
 - [x] Bold, italic, inline code, strikethrough
 - [x] Inline code strips backticks
 - [x] `some_var_name` NOT italicized
 - [x] `a * b * c` math not italicized
 - [x] Blockquote `│ ` prefix
 - [x] Bullet `•` transformation
 - [x] Numbered list preservation
 - [x] Task items `[ ]` / `[✓]`
 - [x] Horizontal rule
 - [x] Links: styled text + URL, OSC 8 codes present
 - [x] Images: `Image: {alt} → {url}` format, OSC 8 codes present
 - [x] Nested inline in blocks (bold in heading, code in list)
 - [x] Partial spans in `render_line`
 - [x] `theme=None` degrades to raw stripped text (no colors, but syntax stripped)
 - [x] `raw_markdown=true` matches current behavior byte-for-byte
 **Commit:** `test(render): comprehensive coverage for rich markdown renderer`
 ## Phase 2 (Follow-up PR) — Tables
 Deferred scope. Rough sketch:
 - Add `Option<TableBuffer>` field to `MarkdownRender`
 - On table row detection, accumulate rows in buffer (emit raw markdown for now to keep streaming visible)
 - On non-table line (or blank), flush the buffer: compute column widths, render with box-drawing chars, emit
 - Handle streaming: use cursor-erase to replace raw rows with rendered table when buffer flushes
 - Test coverage: single-column, multi-column, alignment specifiers (`:---`, `---:`, `:---:`), empty cells, long content wrapping
 ## Success Criteria (Phase 1)
 - [x] All existing tests pass with `raw_markdown: true`
 - [x] All new tests pass with `raw_markdown: false`
 - [x] `cargo check` clean
 - [x] `cargo test` all pass
 - [ ] Manual REPL test: streaming looks smooth (no flashing, no visible partial spans getting re-rendered)
 - [ ] Manual REPL test: `.set raw_markdown true` reverts to current behavior
 - [ ] Manual test: user's custom theme colors apply to headings/bold/etc. (not just default)

 Append-only. One entry per commit or session.
 ### 2026-07-22 — Planning complete
 - Scoped implementation via research (glamour source, syntect scope conventions, current renderer consumers)
 - Resolved 3 open design questions (tables deferred, glamour hash prefixes matched, OSC 8 with fallback)
 - Wrote this plan file
 - Next: hand to Momus for review before starting Phase 1.1
 ### 2026-07-22 — Phase 1.1 complete (`d2940a8`)
 - Added `resolve_scope_style` helper + `MarkdownStyles` struct with 10 constructs, precomputed once in `MarkdownRender::init`; new struct is `#[allow(dead_code)]` until Phase 1.5 wires it in. 6 new tests cover primary/fallback/default paths, `theme.is_none()`, built-in dark theme, and a minimal-root-scopes theme.
 ### 2026-07-22 — Phase 1.2 complete (`f40ba4c`)
 - Added `LineKind` enum (Heading/Blockquote/TaskItem/BulletItem/NumberedItem/HorizontalRule/Paragraph) and `detect_line_kind()` using `fancy_regex` for the 6 block patterns. Wired into `check_line` — signature now returns `(LineType, LineKind, Option<SyntaxReference>, bool)`; callers ignore `LineKind` with `_` until Phase 1.4. 8 new tests cover each pattern plus edge cases (`##notheading`, `-nospace`, `--`, indented items, empty blockquote).
 ### 2026-07-22 — Phase 1.3 complete (`89db5b3`)
 - Added inline regexes (INLINE_CODE, IMAGE, LINK, BOLD_AST, BOLD_US, ITALIC_AST, ITALIC_US, STRIKETHROUGH, CODE_PLACEHOLDER) and `apply_inline()` running the plan's 6-step pipeline. Refined italic regexes with `(?!\s)` opener + `(?<!\s)` closer to prevent `a * b * c` false-positives while still requiring the word-boundary lookbehind for `some_var_name`. Inline code is masked with `\x00C{idx}\x00` placeholders before other transforms so its content is never re-parsed. Links/images wrap in OSC 8 hyperlink codes. 15 new tests cover each construct, order-dependence, partial spans, italic false-positives, OSC 8 emission, and image-before-link ordering.
 ### 2026-07-22 — Phase 1.4 complete (`9890cf0`)
 - Added `render_markdown_line(line, kind, styles)` dispatcher plus per-`LineKind` block renderers (`render_heading`, `render_blockquote`, `render_bullet`, `render_numbered`, `render_task`, `render_hrule`). H1 gets space-padded, H2-6 keep their `##...` prefix; blockquotes get `│ `; bullets → `•`; numbered items keep the number and style only the `.`; task items → `[ ]` / `[✓]`; hrules render as `────────`. All block variants delegate leftover content to `apply_inline`. 15 new tests cover each block type, indent preservation, and nested inline (code in bullet, link in blockquote).
 ### 2026-07-22 — Phase 1.5 complete (`d65d63e`)
 - Wired the rich renderer into `render_line` / `render_line_mut`: code lines still route to syntect; non-code lines branch on `options.raw_markdown` (true → existing markdown-grammar syntect path, false → `render_rich_markdown_line`). Removed `#[allow(dead_code)]` from `RenderOptions::raw_markdown`, `MarkdownStyles`, `LineKind`, `detect_line_kind`, `render_markdown_line`, `apply_inline`, and the `styles` field. Updated the 3 existing tests (`no_theme`, `no_wrap_code`, `wrap_all`) to set `raw_markdown: true` — they still produce byte-identical output, proving the raw path is preserved. Manual REPL/streaming tests deferred to user.
 ### 2026-07-22 — Phase 1.6 complete (`b0eeba1`)
 - 6 more tests filling out the coverage checklist: bold nested inside a heading, partial bold/link spans via `render_line` (streaming path), rich rendering with `theme=None` still strips syntax and emits block glyphs, rich vs raw paths diverge on the same input, and fenced code blocks still route through syntect. Total: 55 markdown tests, 1207 total tests pass, `cargo check` clean.
 ### 2026-07-22 — Phase 2 complete (Phase 1 successor shipped)
 - Phase 2 (tables + hanging-indent list/blockquote wrapping) is complete on top of this foundation. See `rich-markdown-renderer-tables.md` for the full plan and per-sub-phase progress log. Final commits: `fcc4a1d` (2.1) → `7671d28` (2.2) → `c062f34` (2.3) → `cdfaa0f` (2.4) → `bf06d5e` (2.5) → `d790782` (2.6) → `e82e5ab` (2.7). Total markdown tests grew from 55 → 94; total test suite 1207 → 1246, all passing, `cargo check` clean.
