todo: mark terminal coherence pass as landed

layout
- unified prefix-column for every row kind: padding-left + negative
  text-indent so the glyph (→ ← · ◆ ✓ ✗ ⌁ !) sits in the same column
  whether the row is flat or a <details>. wraps hang under the body,
  not under the glyph.
- expandable rows drop the directional glyph from their summary text;
  the ▸/▾ disclosure marker from CSS sits in the prefix column instead,
  and the row's colour still carries cyan = outbound, muted = inbound.
- turn-start / turn-end de-weighted: bold/margin/tint dropped, the
  coloured left rule alone marks the boundary.

note classification
- stderr lines render orange with a `!` glyph (was muted `·`)
- operator-initiated notes (cancel/compact/model/new-session) render
  mauve italic (was muted `·` indistinguishable from harness chatter)
- catch-all .sys row escalates to orange `!` so unrecognised stream-json
  shapes surface for follow-up instead of hiding in muted noise

message-bearing rows
- send / ask / answer tool_use rich renderers default-open with the
  body inline; new ask + answer renderers (previously fell through to
  the generic JSON dump). recv tool_result also default-open, keyed by
  tracking tool_use_id → name across the stream so we know which
  result came from which tool.
- assistant text rows render markdown.
- bodies use vendored marked v4.0.2 (hive-fr0nt::MARKED_JS); falls
  back to plain text when the asset doesn't load.

extra-mcp tool pretty-print
- generic args formatter replaces the raw JSON dump for unknown tools
  (single-string field → `name k: "v"`; single dict / multi-field →
  trimmed `k: v · k: v …` summary)

dashboard .live .msgrow gets a text-indent: 0 reset so the new
hanging-indent metrics from TERMINAL_CSS don't leak into the flex-grid
broker rows.

+## Harness Behaviour
+
+- **Persist + cold-load current context size on the per-agent page**: the `ctx-badge` (Claude Code's bottom-right "N tokens" indicator) currently only populates after the first `TokenUsageChanged` SSE event arrives, which is the *next* turn — until then the badge is empty. Operator can't see "this agent is at 78% context" before deciding to manually compact / reset / message it. Last known token usage should be persisted (likely a small `/state/hyperhive-token-usage` blob, or a row in turn_stats already has it — pull last row's totals on cold load) and returned by `/api/state` so the badge paints with real numbers on first render.
+
+- **Auto session-reset when context is large and cache is cold**: today every turn uses `--continue`, so a long-lived agent carries its entire transcript forward indefinitely. When the next turn's context is above some threshold (rough starting point: ~50% of the session limit — hive startup alone burned ~15%, so the headroom disappears fast) *and* the prompt cache is no longer warm (last turn ended past the cache TTL), it's cheaper to start fresh than to re-send the whole history uncached. Open question: drop `--continue` vs. trigger `--compact` first — needs measurement of what each actually costs (uncached re-read of N tokens vs. a compact turn's own token spend + the post-compact uncached re-read). Decision should be data-driven, not guessed. Needs: a context-size estimate per turn (turn_stats already tracks token usage), a cache-warmth heuristic (time since last turn vs. cache TTL), and a one-shot fresh-session path in `turn.rs` mirroring the existing `↻ new session` button.
+
 ## Bugs
 
 - **Token-budget exhaustion crashes the harness**: when claude's account hits its rate/token cap, the in-flight `claude --print` invocation returns an error the harness doesn't recognise as recoverable, the serve loop exits, and the container stays up with a dead daemon. Operator only notices when an unrelated wake fails to drive a turn. Want: detect the budget-exceeded class of failure (likely a specific stderr line or stream-json `rate_limit_event` shape), fire a `LiveEvent::StatusChanged("rate_limited")` or new status, surface as a red badge + banner on the dashboard + per-agent UI, and have the serve loop park (sleep N minutes, retry) instead of returning Err. Operator can also see "this agent is rate-limited until ~HH:MM" if claude tells us when. Inspect `crate::turn::run_claude`'s `bail!` paths + claude's stderr conventions for the budget error string.

+7. **Turn-start / turn-end are visually overweight**: the
+   triggering event row + the closing row both get bold text,
+   top margins, and a full coloured background tint. The
+   coloured left rule alone already says "this is a turn
+   boundary" — the heavy chrome adds noise without information.
+   Drop the bold/margin/tint, keep the left rule.
+
+8. **Left-alignment is incoherent across row types**: the `▸`
+   disclosure marker on expandable rows doesn't sit in the
+   same column as flat-row prefix glyphs (`→`, `←`, `·`), so
+   the prefix column wanders by row kind. Expandable tool_use
+   (`→ Name …`) and expandable tool_result (`▸ ← Nl …`) use
+   different layouts from each other too. Pick one prefix
+   column and align every row kind into it; the disclosure
+   marker should be visually inside that column, not pushed
+   to the side.
+
+9. **Continuation lines aren't inset**: when a row's body
+   wraps (e.g. `→ foo bar baz quux …`), the second visual
+   line starts at column 0 rather than under the `f` of
+   `foo`, so wrapped content blurs into the next row. Want a
+   `text-indent` / hanging-indent rule so continuation lines
+   align with the start of the body, not the prefix glyph.
+
+10. **Most message-bearing rows are collapsed by default**
+    even when the body is the whole point: `send`, `recv`,
+    `ask`, and friends hide their text behind a `<details>`
+    summary. The summary headline is rarely enough context.
+    Want these expanded by default, with collapse reserved
+    for genuinely heavy payloads (multi-page diffs, long
+    tool_result blocks).
+
+11. **Tools from extra MCP servers aren't pretty-printed**:
+    `renderRichToolUse` only special-cases the built-in
+    hyperhive tools (Write/Edit/send). Anything coming from
+    `extraMcpServers` (matrix, bitburner, …) falls through
+    to the generic `→ Name args…` JSON dump. Either a
+    plugin-style hook in the renderer map, or at minimum a
+    nicer generic args-pretty-printer that handles common
+    shapes (single string arg, single dict arg, etc.).
+
+12. **No markdown rendering on message bodies**: `send` /
+    `recv` / `ask` / `answer` / agent text content all
+    arrive as markdown-flavoured prose (bullets, fenced
+    code, bold, links) but render as raw text. Want a

+### Layout rules to apply uniformly
+
+- **One prefix column for every row kind** — flat rows and
+  expandable rows alike. The disclosure marker (`▸`) lives
+  inside that column, not as a separate gutter, so glyph
+  alignment doesn't shift between row types.
+- **Hanging indent on wrapped bodies** so continuation lines
+  start under the first character of the body, not under the
+  prefix glyph. Probably `display: grid` with
+  `grid-template-columns: <prefix-col> 1fr` per row, or
+  `text-indent`/`padding-left` with negative `text-indent`.
+- **Turn boundaries are rule-only** — drop the bold + margin
+  + tint on `.turn-start` / `.turn-body` / `.turn-end-*`.
+  The coloured left rule alone carries the boundary signal.
+- **Default-expanded message rows**: `send`, `recv`, `ask`,
+  `answer`, and short-ish `text` rows render their body
+  inline (no `<details>`). Reserve collapse for genuinely
+  heavy bodies — multi-page diffs, long tool_results,
+  thinking blocks past N lines.
+
+### Renderer surface for extra MCP tools
+
+`renderRichToolUse` currently switches on hard-coded tool
+names. Replace with a registry keyed by
+`mcp__<server>__<tool>` (and the built-in claude tool names)
+that maps to a `(toolUse) -> Node` renderer. Per-agent extra
+MCPs can register their own renderers via a small JS hook
+(loaded the same way `extra-mcp.json` is loaded server-side);
+the fallback is a generic args-pretty-printer that handles
+single-string and single-dict shapes nicely instead of dumping
+raw JSON.
+
+### Markdown rendering
+
+Apply a minimal markdown pass to message bodies (`send` /
+`recv` / `ask` / `answer`) and to assistant `text` rows.
+Scope: paragraphs, lists, fenced + inline code, bold/italic,
+links. No HTML passthrough, no images, no tables —
+explicitly bounded so we don't import a kitchen-sink parser
+into the per-agent page. A small handwritten pass or a tiny
+dep (e.g. `micromark` / `marked`) both work.
