Three UX improvements for the live build log viewer:
1. Auto-scroll (sticky-bottom): live build output now scrolls to the
bottom as new lines arrive. Stops auto-scrolling when the operator
manually scrolls up; resumes when they scroll back to the bottom.
Same intent-tracking pattern used by the terminal pane.
2. Elapsed-time ticker: running builds show a live seconds/minutes
counter in the row header that ticks every second. Stops and shows
the final duration when the build finishes (done frame received)
or errors out.
3. SSE-driven list refresh: subscribes to /dashboard/stream and
debounces a fetchBuild() call (2s) whenever rebuild_queue_changed
fires while the BUILD tab is active. New log entries and status
changes appear without a manual refresh.
Same cleanup as the previous pass (tabs.js, app.js): replace
innerHTML = '' with replaceChildren() and lowercase the one
uppercase 'HTTP' error in logs.js.
- live detection: use !h.status (null while running) not === 'running'
- SSE: replace named addEventListener('chunk'/'done') with onmessage +
frame.done check — backend sends generic message events, no named type
- SSE payload: use frame.stdout_append/stderr_append not frame.text
- timestamps: started_at/finished_at are unix seconds, multiply by 1000
was already done implicitly — actually use unix arithmetic directly
to avoid new Date() confusion entirely
Also move the misplaced .flow-main-slim rule from the logs section to
the flow-shell section of dashboard.css.
Add /logs.html as a standalone page (same back-link pattern as flow.html):
- BUILD tab: all-agents build log history via new GET /api/build-logs endpoint
- AGENT tab: per-container journald viewer with agent selector + unit filter
- SYSTEM tab: host-side hive-c0re.service logs via new GET /api/journal-host endpoint
Remove inline log drill-ins from SW4RM container rows (buildJournalTrigger
and buildBuildLogsTrigger) — log viewing now lives on the dedicated page.
flow.html: strip the full dashboard tabbar, replace with a simple back link
matching the new logs page chrome.
index.html: add L0GS tab link to /logs.html in the tab strip.
Backend additions:
- build_logs::list_recent_all — cross-agent query (newest first, cap 100)
- GET /api/build-logs — all-agents variant backed by list_recent_all
- GET /api/journal-host — host journald (no -M container flag), restricted
to allow-listed units (hive-c0re.service)
