Move terminal-row classification server-side into a new
hive-agent/src/term_msg.rs, replacing the old JSON-mutation
enrich()/stamped-field approach in stream_enrich.rs with one
uniform wire shape: {icon?, level: debug|info|warn|error, summary,
body?, body_format?: markdown|diff, coalesce_key?}. No more per-row
`kind` tag or raw claude-JSON passthrough — every row is the same
shape, with structural identity carried by icon + summary text
instead of a CSS class per row kind.
hive-agent/src/web_ui/stream.rs's history + SSE endpoints now both
call term_msg::classify() and serve TermEnvelope{ts, seq?, msgs}
frames; events that classify to zero rows (agent-state changes,
drop-noise) never reach the wire.
Frontend: classifyEvent.ts collapses from a large per-tool dispatch
tree to a thin TermMsg -> StreamRow adapter. streamRow.ts/Row.tsx
drop the now-dead meta/childText fields. terminal.css switches from
a dozen-odd per-row-kind classes to four level-based color rules.
Expand/collapse of a bodied row is now a uniform client-side
decision (the operator's preference), no server-side per-tool
override.
docs/terminal-rendering.md rewritten to match.
Ports the row taxonomy in docs/terminal-rendering.md (app.js's
renderStream/renderRichToolUse/renderToolResult/renderTaskEvent) to
real Preact components + hooks:
- lib/streamRow.ts: plain-data StreamRow model (one row = one line/
panel), lib/classifyEvent.ts: raw stream-json event -> StreamRow[],
almost entirely dispatching on the backend's precomputed _icon/
_summary/_category/_body/_body_type fields, same as the old client.
- lib/markdown.ts, lib/linkify.tsx: sanitized-markdown + auto-link
helpers, same behavior as app.js's mdNode/terminal.js's linkify.
- hooks/useLiveStream.ts: backfill + SSE + seq-dedupe + coalescing,
reduced to a plain StreamRow[] — deliberately has no opinion on
scroll position, only on what rows exist.
- components/Row.tsx: renders one StreamRow (flat or details).
- components/LiveStream.tsx: owns the scrollable DOM node + a from-
scratch sticky-bottom implementation — not the old MutationObserver
+ rAF snap-animation + smoothScrollingUntil gate. stickToBottom is
plain state driven by the scroll handler; snapping is an instant
scrollTop write in a useLayoutEffect that runs after Preact has
already committed the new rows, so it always sees the real
scrollHeight. A load-older prepend is told apart from a normal
append via an explicit ref set right before calling loadMore(),
rather than inferred from DOM mutation shape after the fact.
Wired into Root.tsx below Header/StatusChips; turn_start/turn_end
also nudge useAgentState's refresh() for a snappier badge update than
the plain poll interval.
Reuses @hive/shared/terminal.css's existing row-kind classes as-is —
the taxonomy's visual language isn't what changed, the component
model underneath it is.
- useAgentState hook: polls GET /api/state (4s interval for now — see
its file comment for why this isn't yet the SSE-triggered + login-
only-timer cadence the old page used; that lands with the live
stream + term-input commit, which is when clobbering the operator's
in-progress input actually becomes a risk).
- format.ts: fmtTokens/fmtAge, same output shapes as app.js's.
- modelEffort.ts: POST /api/model + /api/effort (same-origin, plain
fetch).
- dashboardBase.ts + pauseAction.ts: pause/resume POST to the
*dashboard's* origin via a real <form> submit, kept unchanged from
app.js — a cross-origin fetch needs CORS headers hive-c0re doesn't
send, a form submit sidesteps that same as it already did.
- Root.tsx: wires it all together, including app.js's "any non-online
status forces the turn-state badge to offline" behavior.
Screenshot-verified against a mock GET /api/state (real fetch, not
hardcoded props) + the real agent.css/theme.css/colors.css.
Builds + tsc --noEmit clean.
