The output-layout block was written before:
- the dashboard's app.js → tabs.js rename (#495)
- the flow.html / flow.js page (#406 / #485)
- the SharedWorker stream-worker.js (#448)
- the build.mjs split-into-static/ subdir convention
Brings the comment in line with what `find dist -type f` actually
prints for both packages. Pure documentation refresh; install phase
and build hashes untouched.
Every field on the new- and edit-schedule forms (plus buildIntervalComposer
and buildTargetChips) builds the same wrapper shape:
el('label', { class: 'schedule-field' },
el('span', { class: 'schedule-field-label' }, '…'))
then appends an input. Eight identical-modulo-text sites. Extracting one
small helper:
function scheduleField(labelText, ...children) {
return el('label', { class: 'schedule-field' },
el('span', { class: 'schedule-field-label' }, labelText),
...children);
}
drops the per-site cost to a single `form_.append(scheduleField('caption',
input));` line. -10 LOC net; no behaviour change.
argus pointed out the inline catch comment claimed dead ports get cleaned up on
next subscribe, but nothing actually prunes the allPorts Set on subscribe — the
honest answer is the one already at the bottom of onconnect: dead entries are
left in the Set, the bound cost is acceptable, and postMessage's throw is the
ambient signal we use. Point at that comment instead of repeating a wrong
description.
Firefox kills "idle" SharedWorkers under memory pressure with no native
signal to the client. The page's port silently becomes a no-op and
events stop flowing — observable symptom: mara's "dashboard never
refreshes; F5 fixes it" (because F5 creates a fresh page that creates
a fresh worker).
The worker now pings every connected port every 30s. The client tracks
last-activity-from-worker on every message arrival (incl. pings, since
those carry no URL — bumped before the URL filter in the route handler).
A visibility-gated watchdog polls every 15s; if the page is visible AND
has active subs AND hasn't heard from the worker in >90s, it presumes
the worker dead, logs a console warning, and re-subscribes on a fresh
port. Three pings missed before we act, so a normal tab-throttle blip
doesn't false-positive.
The fresh-port re-subscribe re-uses the bfcache-restore code path
(same shape: drop stale listeners, getSharedPort → new SharedWorker,
re-attach each route + repost subscribe). Recovery is per-tab — when
one tab's watchdog fires and brings up a new worker, other tabs that
share the named worker pick it up on their own watchdog cycle.
Falls back gracefully on environments without SharedWorker (the
existing direct-EventSource path is untouched) and is invisible on the
healthy path — pings are 30s apart, no UI surface.
mara: \"look through the code for dedups, structural improvements
and so on\". Two near-identical blocks across the new-schedule and
edit-schedule forms folded into shared helpers.
## `buildTargetChips({ idPrefix, fieldName, checked, extraNames })`
Was inlined twice in 18-line blocks that built the same
`<label class="schedule-field">` + `<div class="schedule-targets">`
+ candidate-list logic (containers + operator + manager). Now one
function, two callers; `extraNames` lets the edit form keep
showing already-active targets that have vanished from the live
container list so the operator can still uncheck them
intentionally.
## `intervalSecondsFromFormData(fd, namePrefix)`
Both submit handlers had the same ~13-line d/h/m/s → total-seconds
parser (with `NaN` propagation on bad input). Pulled into one
helper next to `buildIntervalComposer`; call sites become 3 lines:
const intervalTotal = intervalSecondsFromFormData(fd, 'interval_');
if (Number.isNaN(intervalTotal)) { alert(...); return; }
const interval_seconds = intervalTotal > 0 ? intervalTotal : null;
Net -13 lines, but the bigger win is shape — when (not if) a new
schedule field surfaces, there's one chip-render path + one
interval-parser to thread it through instead of two.
Zero behaviour change. Built clean.
argus 🟡 on #504 — `font-variant-numeric: tabular-nums` has no
effect on `.rqe-step` since step strings are text-only
("nixos-container update" / "meta prepare_deploy" / etc.),
no digit columns to align. Harmless but cleaner without it.
Frontend half of #437 — paired with damocles's #501 backend which
adds `step: Option<String>` to `QueueEntry` and annotates 9
worker phases across ApplyCommit / Spawn / MetaUpdate / Rebuild
pipelines.
When `entry.step` is present, render a cyan `↳ <step>` sub-line
below the main row in `renderQueueEntry`. Wraps to its own flex
line via `flex-basis: 100%`, indented 1.8em to align under the
state glyph + kind. Terminal transitions clear `step` on the
backend, so the sub-line just disappears on Done / Failed rows —
no client-side staleness handling needed.
CSS: `.rqe-step` keys off cyan to visually group with the
running-spinner color cue (vs the muted `.rqe-when` /
`.rqe-reason` chips). `tabular-nums` keeps the indented arrow
column stable as step strings change length mid-build.
docs/web-ui.md updated to describe the new sub-line behaviour
in the R3BU1LD QU3U3 section.
Frontend half of #408 — wires flow.js's terminal subscribe URL to
the kinds-filter damocles shipped in #499. Only the four kinds
flow.js actually handles get sent on the wire:
- sent / delivered → broker terminal renderer
- container_state_changed / container_removed → local autocomplete
cache (flowContainers Map used by the @-mention composer)
Everything else (approval_*, question_*, transient_*, tombstones_*,
meta_*, rebuild_queue_*) is now dropped server-side before the
JSON-serialise, instead of being deserialised + dispatched to
flow.js's no-op `_default: () => {}` per frame.
Tabs.js keeps the unfiltered `/dashboard/stream` subscribe since
it routes every mutation kind into its derived stores.
## SharedWorker note
`openStream` keys subscriptions by full URL (#448, #453). The
filtered URL is therefore its own upstream connection to
hive-c0re — when both /index.html and /flow.html are open at the
same time the worker holds two upstreams (one filtered, one full)
instead of today's single shared upstream. The trade is small
per-frame wire-byte + serialise savings vs +1 backend connection
in the both-open case. The flow-page-only case is a pure win.
Acceptable per #408's intent ("split flow messages from main
endpoint").
Round-trip note: if the backend's `kind_tag` strings ever drift
from what's listed here, the affected kind silently never matches
and flow loses that event class. damocles's #499 added a serde
round-trip test against `kind_tag` to guard the backend side;
the frontend mirrors the spelling exactly from the PR body.
#406 was the JS-split refactor: pull shared helpers into
common.js (step 1), pull the flow-only IIFEs into flow.js
(step 2), then rename the legacy combined entry from app.js
to tabs.js (step 3 — this commit) to reflect that the bundle
now owns the dashboard tabs surface only.
What moved:
- `frontend/packages/dashboard/src/app.js` → `tabs.js`
- `build.mjs` entry: `src('app.js')` → `src('tabs.js')`;
output is now `static/tabs.js`
- `index.html` `<script>` src: `/static/app.js` →
`/static/tabs.js`; the FL0W-section comment retouched
- `flow.html` reference from `/static/app.js`-as-tabs to
`/static/tabs.js`; notif + offscreen-inbox comments rewired
to point at the correct owners (common.js for NOTIF,
flow.js for renderInbox)
- `common.js`, `flow.js`, `tabs.js` headers: scrub stale
"app.js" references; document that #406 steps 2 + 3 are
done and both pages import directly from common.js
- `dashboard.css` comments: every "by app.js" → "by tabs.js"
- `docs/web-ui.md`, `docs/conventions.md`: legacy
`assets/app.js` → `assets/tabs.js` (the path prefix is
itself stale from a much-earlier rename, but consistent
with the rest of those docs)
- `CLAUDE.md` file map: refresh the dashboard package's
src/ and dist/ layouts to reflect the post-split shape
(tabs.js, flow.js, common.js, stream-worker.js)
What did NOT move:
- `frontend/packages/agent/src/app.js` (per-agent UI entry)
stays named `app.js` — it's a separate package, has only
one entry point, no split happened there
- The two "no-op when target absent" guards in renderContainers
and renderQuestions are kept as belt-and-suspenders for any
future page that adds tabs.js without the corresponding
sections; comments updated to note this rather than the
pre-split flow.html reason
Functional behaviour identical; this is a pure rename + comment
sweep.
mara: "the 'timestamp from -> to' part is long enough to warrant
its own line. then the actual messages can be rendered (nearly)
full width."
Confirmed in the layout — previously `.live .msgrow .msg-body`
sat inline with `flex: 1 1 0`, eating whatever the chips left.
With a 14:23:42 timestamp + agent names + arrows that was ~30ch
of prefix; long bodies wrapped awkwardly.
One-line CSS fix: `flex: 1 1 100%` on `.msg-body` forces it to
wrap to its own flex line in the existing `flex-wrap: wrap`
container. Metadata chips stay on the row above; body takes the
full width down to the row's content edge.
`min-width: 0` retained so `word-break: break-word` keeps
working. Reply rows keep their `padding-left: 1.2em` border-left
indent — the body lands within that frame, matching the visual
"this is a reply" nesting.
Out of scope but worth knowing:
- consecutive-message grouping (one header per agent run) was
the second design option I floated; happy to land it as a
follow-up if reading still feels chatty.
- timestamp-on-hover was the third; skipping unless asked.
mara: "why can this even be an issue?" — fair. The SCH3DUL3S
tab was added to index.html's chrome in #459 but flow.html's
parallel tab strip was never updated to match. The flow page
operator hit a dead end going back to the schedules pane.
One-line fix: copy the same `<a class="tab" href="/#schedules"
role="tab" data-tab="schedules">` link from index.html into
flow.html's chrome, positioned between SYST3M and FL0W to match
the dashboard ordering. Count pill stays hidden (flow.js
doesn't sync `schedulesState` — same reason SW4RM/Y3R C4LL/
SYST3M pills also stay hidden on this page).
mara confirmed target editing on q #195 ("also let me edit targets").
Damocles wired `targets_add` / `targets_remove` onto PATCH
/api/schedules/{id} in #478. UI side: the schedule edit form's
read-only targets callout becomes a multi-select checkbox box
(same chip styling as the new-schedule form) pre-checked for
currently-active targets.
Submit logic:
- diff new selection against `originalActiveTargets` to populate
`targets_add` (checked, not originally active) and
`targets_remove` (originally active, now unchecked)
- only include each key in the PATCH body when non-empty
- guard against zero-target submission with a clear alert
pointing the operator at `✕ cancel all` as the intended path
- already-active targets that aren't in the live candidate list
(e.g. a since-destroyed container) still surface so the
operator can intentionally drop them
Note (re-add semantics): backend's replace-on-conflict drops
the cancelled-target tombstone + history on re-add — per the
design discussion with damocles, operator intent on re-adding
reads as "fresh start, target is active again." UI copy below
the chip row reflects this.
Carry persistence extended to the `targets` array so the
checkbox state survives a state-poll re-render mid-edit;
listens on `change` in addition to `input` for checkbox events.
argus 🟡 nit on #480 — the `if (!rows.length)` block sat at +6
inside the paintAtomic callback, but the `const ul` + for loop
underneath stayed at the pre-wrap +4. Code was correct, just
visually inconsistent. Re-indented the whole callback body
uniformly.
renderScheduleNewForm has the same cosmetic mis-indent but its
body is ~100 lines; leaving that for a separate sweep so the
diff stays focused.
argus flagged + mara confirmed: operators see a brief "blink" on
every poll cycle when refreshState fires. Root cause for the
async-fetch sections (refreshReminders, refreshSchedules): the
`await resp.json()` yield is a paint opportunity the browser can
take BEFORE the renderer's `root.innerHTML = ''` + `root.append`
land. The "loading…" placeholder (or the previous render's stale
content) may briefly show through.
Fix: render off-DOM into a `DocumentFragment`, then atomically
swap into the live root with `replaceChildren`. The browser only
sees the new content; no intermediate empty state is reachable.
Added `paintAtomic(liveRoot, build)` helper near the top of the
IIFE — minimal-churn pattern where each renderer's existing
`root.append(...)` body carries over unchanged, just wrapped in
a builder callback that receives the fragment as its `root`
parameter.
Applied to the async-fetch sections argus's note + mara's report
specifically called out:
- `refreshReminders` (both http-error + catch paths)
- `renderReminders`
- `refreshSchedules` (both error paths)
- `renderScheduleNewForm` (carry read still happens against the
live root BEFORE the swap so mid-typing values are preserved)
- `renderSchedulesList`
Kept scope tight to the async paths. The sync renderers
(renderContainers / renderTombstones / etc.) run inside the
same JS turn as refreshState's other sync work, so the browser
can't paint between their clear+populate steps — no flash to fix
there. If mara still sees blink on those sections after this
lands, extending the pattern is a clean follow-up.
docs/web-ui.md no change needed; this is an implementation
detail of the existing managed-section render machinery.
