Pure `nix fmt` output from the commit before this one — no hand edits. 203 files: 52 md, 42 tsx, 32 js, 32 css, 21 ts, 13 html, 8 json, 3 mjs. Reproduce with `nix develop -c nix fmt` on the parent commit; the result should be byte-identical to this tree. None of the 13 `.prettierignore` entries appears here — verified by intersecting the changed-file list against the ignore file, with a control proving the intersection finds a match when one exists.

Web UI
Two web surfaces share the same skeleton: the dashboard (port 7000)
and the per-agent UIs (each container's port is a deterministic hash
in :8100-8999 — see
gotchas.md#web-ui-ports-collide-on-hash
for the mechanics and the collision caveat).
Both are SPAs — GET / returns a static shell, /api/state
returns JSON, JS renders. No full-page reloads.
This doc has been split for readability. Pick the section you need — or, if you're the operator looking for how to actually use the dashboard rather than how it's built, start at web-ui/README.md instead.
- Shape (shared by both) — shared SPA
skeleton, SSE multiplexing, terminal pane, listener bind,
per-agent relative paths,
data-asyncform pattern, side panel, atomic repaint. - Dashboard layout — tab contents
(SW4RM, Y3R C4LL, P3RM1SS10NS, SCH3DUL3S) + standalone pages
(C0R3
/core.html, BU1LDS/builds.html, L0GS/logs.html, CR3D3NTIALS/credentials.html), container row, topology tree, selection bar, approval card, browser notifications, dashboard endpoints + event channel. - Per-agent page — header, main terminal, composer, side panel + inbox, live view, slash commands, per-agent endpoints, stats page.
- CSS theme variables — the Catppuccin
Mocha custom properties declared once in
base.cssand the rule that per-page stylesheets reference (never redeclare) them. - swarm-ui design guide — visual
language, motion, theming, error-UX, and component-first principles
for the swarm-level Preact app specifically (not this doc's
dashboard/agent UIs).
/componentson a running swarm-ui is the companion living demo of every primitive it references.
