Adds @hive/shared/tabs.js — createTabStrip(tabbar, {defaultId, onShow}):
a hash-routed tab strip that resolves controls by `[data-tab="<id>"]`
inside the passed container and panels by `[data-tab-pane="<id>"]`,
toggling `.hive-tab--active` + aria-selected + the panel's `hidden`, and
firing onShow(id) for per-tab side-effects. Always hash-routed (deep-
linkable + back/forward), no element-resolver callbacks (convention over
config), per the #1464 design review.
Wires it up: @hive/shared exports `./tabs.js` + `./tabs.css`, and
common.css @imports tabs.css (component structure, not a swap target, so
inlining is fine — unlike theme.css).
Migrates the logs sub-tabs as the first consumer: markup uses
`.hive-tab`/`data-tab`/`data-tab-pane`, logs.css drops the duplicated
base styles (keeps only its `flex:1` layout delta), and logs.js swaps its
activeTab/showTab/hashchange for createTabStrip (onShow lazy-loads the
SYSTEM tab). Behaviour-preserving. aria-selected is now standardised.
Per operator request: instead of a disk-specific alert, surface a generic
server-warnings banner at the very top of every page, so new system
warnings can be added backend-side with no frontend change.
- hive-c0re `host_stats`: `server_warnings() -> Vec<ServerWarning>`
(`{ kind, level, message }`). The threshold logic lives server-side; the
host disk-pressure check (a `statvfs` probe of `/nix`: ≥85% used → warn,
≥95% → crit) is the first and only producer today. No new deps (libc).
- `/api/state` carries `server_warnings` (replaces the disk-specific
field). Empty when all clear.
- frontend: `renderServerWarnings` / `initServerWarnings` in `common.js`
inject a sticky top-of-<body> banner and render the list, coloured by
`level`. Wired on every page — dashboard (live, via refreshState),
FL0W, L0GS, H0M3. No per-warning frontend code; adding a warning kind
is a pure backend change.
cargo check/clippy/fmt + npm run build green. Closes#1518.
Adds ?agent=name and ?unit=svc URL params to pre-select the agent on
the AGENT tab (used by the per-agent overflow menu journal logs link).
Last-fetched timestamp chip shows how stale the output is.
Agent selection is NOT persisted to localStorage — URL params only.
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)
