A terminal row published on `$SWARM.term.<hive>.<agent>` goes out bare,
with no envelope around it and no server-side stamp, so a subscriber had
nothing to place the row in time with beyond its own receipt clock —
wrong by the queue's latency and meaningless for anything read later
than live.
`TermMsg` gains `ts`, ISO 8601 UTC. `classify` takes the event's own
unix-seconds stamp and applies it to every row that event expands into,
so a row replayed out of sqlite says when it happened rather than when
it was read, and a row that sat in a lagging subscriber's buffer does
not lie about its time. The oversize degrade keeps it; only the body is
ever spent.
`TermEnvelope` stops duplicating `ts` and keeps `seq`: the dedup counter
is a real transport concern, the event's time is not, now that it rides
on the row. Nothing in the frontend read `envelope.ts` — only the type
declared it.
Refs #4321
ClassifyCtx's tool_use-id correlation gates markdown-vs-plain body
format for a recv result, not open/collapsed state — that's always
the operator's uniform preference now. 5 backend comments still
described it as controlling "default-open" rendering, contradicting
the actual render path and this PR's own rewritten docs.
Also fixed useAgentState.ts's stale comment promising an
SSE-triggered refresh model "in a later commit" — that's permanently
off the table now that the terminal stream's kind tag is gone by
design (argus flagged this as a drive-by, not blocking, but it's a
one-line cause-and-effect of this same PR so fixing it here).
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.
Phase 2 of hyperhive#2196. The backend now pre-computes enrichment fields
on every SSE event (stream_enrich.rs); the frontend reads them directly
instead of running its own dispatch logic.
Removed (~330 lines of JS):
- fmtArgsGeneric / TOOL_ICONS / toolIcon / fmtRoom / fmtUser / fmtToolUse
renderStream changes:
- system events: dispatch on v._category (drop/thinking_tok/note/details)
+ v._summary / v._body instead of per-subtype if-chains; status tick
still overrides label client-side when stateName === 'compacting' since
elapsed time is a wall-clock value the backend cannot know at emit time
- tool_use: use c._category === 'rich' for rich-renderer routing,
c._icon / c._summary for flat rows
renderRichToolUse: toolIcon(name) -> c._icon (from backend enrichment)
stream_enrich.rs: also stamp _category: 'drop' on top-level
type=result / type=rate_limit_event so the frontend can use a single
_category check instead of separate type-based early returns
Move per-message rendering logic from frontend JS to backend Rust.
A new stream_enrich::enrich() function stamps display fields onto
LiveEvent::Stream payloads at SSE-emit time (both live tail and history
replay), so the frontend can consume pre-computed fields instead of
re-implementing the dispatch logic in JavaScript.
Phase 1: backend stamps _icon/_summary/_category; client falls back to
its own JS tables when absent. Zero user-visible change.
- system events: _category (drop/thinking_tok/note/details) + _summary
and optional _body (commands_changed expands to a slash-cmd list)
- assistant tool_use entries: _icon + _summary per tool; rich tools
(Write, Edit, send, ask, answer) get _category: 'rich'
- enrichment applied in web_ui/stream.rs at emit time; DB stores raw
events so no migration is needed when enrichment logic changes
- idempotent: existing _-prefixed fields are left unchanged
