The canvas host is a position:relative BLOCK, so flex:1 on MissionCanvas's root
was inert and its height collapsed to its content. That starved the scroller
beneath it — scrollHeight === clientHeight — so it never scrolled, and the
overflow spilled past the page and was clipped by the host's overflow:hidden.
Long results were rendered and then thrown away. Every sibling canvas already
used position:absolute; inset:0; missions was the only one that did not.
Measured after, on a brief 5x the viewport: one scroller, clientH 736 vs
scrollH 3244, scrolling 0 -> 2508 (exactly scrollH - clientH, i.e. the true
bottom), zero page overflow, tab strip pinned throughout.
Also removed five nested scrollers (70vh on live events; maxHeight caps on run
streams, phase summaries, artifact bodies and error traces). Those existed only
to work around the missing height and would have become portholes onto the very
content the operator is trying to read. The xterm pane keeps its bounded box —
FitAddon needs one, and a terminal owning its scrollback is correct.
Deleting the header's description peek reclaims 104px for results (header
256 -> 152px); the same text renders in full in Setup -> Overview, as the code's
own comment noted.
Streaming now follows only when already at the bottom, via a shared
useStickToBottom hook replacing two byte-identical copies, plus a "jump to
latest" pill neither had. Defaults collapse by mission state, and a remount key
fixes scrollTop leaking between tabs — a bug that only appears once scrolling
works.

The mission page made its own output unreadable. Reviewing a research
brief meant scrolling a 300px <pre> nested inside a 260px run box nested
inside the page scroller (plus a 4th scroll region for the description) —
and the text was capped at 6,000 chars server-side with no way to fetch
the rest, so a 53kB brief showed ~11% of itself and silently dropped the
remainder. Eight flat tabs (overview/phases/tasks/team/live/artifacts/
benchmarks/pane) mixed lifecycle, work items, people, telemetry, outputs
and infra at one level, so nothing indicated where the deliverable lived.
Reader:
- GET /api/missions/{id}/documents lists every agent output (titles +
sizes, no bodies); GET .../documents/{run_id}/{index} returns one in
full. Scoped to the mission so a run id from elsewhere can't be read.
- MissionOutputReader: rail (documents grouped by phase) · document ·
outline (headings, click to jump). Exactly one scroll container per
column, never nested. Copy + download .md.
- MarkdownBlock gains fenced code blocks (agent output is full of ```rust,
previously mangled into paragraphs), h4-h6, heading anchors, and an
outlineOf() helper.
Information architecture:
- Three primary tabs with shallow sub-views: RUN (phases/tasks/live) ·
OUTPUT (documents/artifacts/benchmarks) · SETUP (overview/team/pane).
- PhaseRunsList shows a short excerpt with no inner scrollbar and points
at the reader for the full text.
- The header description is clipped, not scrollable; its full text now
has a home in Setup → Overview.
Missions list:
- /api/missions returns MissionListItem — Mission flattened plus
phases_total/phases_done/current_phase, so the JSON stays a strict
superset. Cards render a progress bar and "Coding · 1/2" instead of a
bare status dot.

- RunOutputPanel: each turn now renders as <details> with a 1-line
peek in the summary. First turn open by default (so operators see
something without a click), subsequent turns collapsed. Same shape
applies to research + coding runs (shared component).
- PhaseSummaryCard: click the header to collapse the whole card;
narrative peek shows in the collapsed state. State persisted per
phase_id in localStorage so it stays remembered across visits.
- PhaseSummaryCard Section: cap max height at 280px with internal
scroll so long tooling / sources / next-action lists dont blow
out the card height.
Adds GET /api/topology-runs/{id}/output — trimmed view of the
runs checkpoint (totals + per-turn output previews, capped at
12 turns × 6kB each). The full checkpoint blob can be hundreds
of KB so it was never viable to send through mission polling.
Phase card run rows now expose a "show output" toggle for any
terminal run (completed/failed/cancelled), rendering turns,
tokens, records count, and per-turn agent text. Running rows
still get the live activity stream from the prior slice.
Diagnostic value: on a mission that "completed" without visible
work, this immediately shows whether the agents produced real
output (workspace missing / instructions vague / etc.) or
whether nothing ran at all.
Adds a "show activity" toggle to any running topology_run row on
the phase card. Expanded rows mount a compact SSE tail from
/api/topology-runs/{id}/events, rendering step/reasoning/tool
events as they arrive — same stream the LIVE tab consumes, just
scoped to one run.
Extracted the phase-runs list into PhaseRunsList to keep
MissionCanvas under the 1250-line budget.
