iris 4539091f3c terminal: show recv wait/max params + bash [bg] flag

recv tool-use rows rendered as a bare recv() regardless of args,
hiding whether a turn is parked on a long-poll (wait_seconds) or
draining a burst (max). fmtToolUse now surfaces both. Bash rows
gain a [bg] flag when run_in_background is set.

Per-agent terminal: row taxonomy (as built)

Snapshot of how the per-agent web UI's live pane renders each event kind today. Source of truth lives in hive-ag3nt/assets/app.js (renderStream, fmtToolUse, renderRichToolUse, renderToolResult, renderTaskEvent, mdNode, detailsOpenMd, fmtArgsGeneric) + hive-fr0nt/assets/terminal.css (the shared .live .<class> styling) + hive-fr0nt/assets/marked.min.js (markdown).

Layout contract

Every row — flat <div class="row …"> and expandable <details class="row …"> alike — shares one prefix column. The mechanism is padding-left + negative text-indent on .live .row: the row's first character (the prefix glyph) gets pulled back into the column at ~0.5em, and wrapped continuation lines hang under the body, not under the glyph.

<details> summaries inherit those metrics. The disclosure marker (▸ / ▾) is supplied by CSS summary::before so it lands in the same column as flat-row glyphs. To make that work the JS-side summary text does not include a directional → / ← — the row's colour (cyan = outbound, muted = inbound) carries the direction, and the prefix column never has to fit two glyphs side-by-side.

Child blocks inside a row (the .md markdown wrapper, an inner <details>) get text-indent: 0 so their content lays out from the body column instead of inheriting the parent's negative pull.

Row taxonomy

`.turn-start`	`◆ TURN ← <from>`	amber, left rule	`LiveEvent::TurnStart`	harness wake
`.turn-body`	(child div under turn-start)	fg	same	the wake-prompt body
`.turn-end-ok`	`✓ turn ok`	green, left rule	`LiveEvent::TurnEnd { ok: true }`	harness
`.turn-end-fail`	`✗ turn fail — note`	red, left rule	`LiveEvent::TurnEnd { ok: false }`	harness
`.text`	(no prefix; markdown body)	fg	claude `assistant.content[].text`	stream-json

`.note`	`· <text>`	muted	harness chatter	`LiveEvent::Note`
`.note.stderr`	`! stderr: <line>`	amber/orange	stderr lines off claude	`LiveEvent::Note` (`text` starts `stderr:`)
`.note.op`	`· operator: <text>`	mauve italic	operator-initiated notes (/cancel, /compact, /model, new-session)	`LiveEvent::Note` (`text` starts `operator:`)

Renderer dispatch

renderStream(v, api) walks each stream-json line:

Drops system/init, rate_limit_event, result (noise / handled elsewhere — result powers the cost badge).
subtype == "task_started" | "task_notification" → renderTaskEvent (subagent activity gets the ⌁ glyph).
type == "assistant" → walk message.content[]:
- text → .text row with a markdown body via mdNode.
- thinking → .thinking row.
- tool_use → record id → name in toolNameById, try renderRichToolUse (Write/Edit/send/ask/answer get custom renderings); on miss fall through to a flat .tool-use row with fmtToolUse → fmtArgsGeneric. fmtToolUse surfaces the salient arg per built-in tool — e.g. recv shows wait <N>s / max <N> when set (bare recv() otherwise), Bash flags [bg] for run_in_background commands.
type == "user" → walk message.content[] for tool_result; renderToolResult correlates via tool_use_id → toolNameById to default-open recv results with a markdown body, else short = flat / long = collapsed details.
Unrecognised shape → .sys row (amber, ! glyph).

Markdown

mdNode(text) wraps window.marked.parse(text) (vendored v4.0.2 UMD via hive-fr0nt::MARKED_JS) in a <div class="md">. CSS in terminal.css scopes paragraph / code / list / blockquote / link styling under .live .row .md so the markdown body doesn't bleed into the row's own text-indent. Falls back to plain text if marked didn't load. Applied to text rows and to send / ask / answer / recv message bodies.

Extra-MCP tools

fmtArgsGeneric(name, input) is the fallback when a tool isn't in the built-in fmtToolUse switch:

single string field → name k: "v"
single number/bool field → name k: v
multi-field → first 4 pairs trimmed to k: "v" / k: [N] / k: {…} with a …+N overflow

This keeps mcp__matrix__send_message and similar from dumping raw JSON.

Dashboard side (not covered here)

The main dashboard's message-flow pane is a different shape: broker messages render as .msgrow grid lines (ts / arrow / from / → / to / body) with their own styling. .live .msgrow explicitly resets text-indent: 0 so the per-agent terminal's hanging-indent metrics don't leak into the flex-grid broker rows.
