Closes#363 (frontend half of milestone #361). Consumes the
`ContainerView.parent: Option<String>` field landing in damocles'
backend slice — when present, the container list renders depth-first
with sibling-position tree glyphs (├─ / └─ joints + │ continuation
columns). When absent (pre-#361 state — every container's `parent` is
None) the tree collapses to a flat list with no glyphs and no indent
— bit-identical to the legacy render.
## Tree shape
- Roots: containers whose `parent` is None OR whose parent name isn't
in the current container set (orphan tolerance).
- Sibling ordering: alphabetical by name within each level (matches
damocles' wire spec at #363#issuecomment-3356).
- Cycle safety: any container not reached via the root-walk gets
emitted as a root at the end — no agent ever silently disappears
from the list when the topology is malformed.
- Tree glyphs: ancestor at depth d contributes a │ continuation column
when that ancestor has more siblings below; otherwise a 3-space gap.
The joint is ├─ for non-last siblings, └─ for the last child.
- Depth-0 ancestor column is suppressed: roots already separate
visually as top-level rows, no need for a column 0 vertical line.
## DOM / CSS
- New `buildAgentTree(containers)` + `treePrefix(node)` helpers in
app.js. The render loop walks the tree-ordered list instead of the
legacy alphabetical containers array.
- Each container row gets `data-depth=N` (only when N > 0) and a
`<span class="tree-prefix">…</span>` prepended (absolute-positioned
into the row's left margin so the existing flex icon/body layout
isn't disrupted).
- CSS: per-depth `margin-left` step rules for depths 1-6 (hardcoded
rather than typed-attr() because CSS Values 5 is Chromium-only as
of 2026). 6 depths cover any reasonable hive topology with
headroom; deeper agents render at depth 6 indent without further
step — visually clamps gracefully.
- `.tree-prefix` rendered with `var(--purple-dim)` so the structural
lines read as supporting chrome, not as content.
## Validation
- `npm run build` clean. Bundle deltas: dashboard app.js
+1.8kb (tree builder + treePrefix + render-loop tweak),
dashboard.css +0.4kb (tree-prefix + per-depth indent rules).
- The render is a no-op until `ContainerView.parent` is populated —
validation in production deferred to once damocles' meta-topology
field lands. The pre-#361 path (every parent=None) is exercised
by every existing dashboard load.
- Forward-compatible with damocles' design pivot at #364 (topology
source moved from agent.nix to meta/topology.json). The wire shape
on ContainerView is unchanged from the frontend's perspective — the
field is just sourced from a different backend store.
The src/index.html / src/stats.html files reference assets at URLs
like /static/app.js, /static/dashboard.css. The initial Phase 1 build
flattened everything to dist/{app.js, dashboard.css, ...} which would
have forced the Phase 4 Rust ServeDir mount to do URL rewriting just
to make the existing HTML references resolve.
Rework: bundles now write to dist/static/, HTML stays at dist/ top
level. Layout matches the URLs the HTML uses, so the Phase 4 mount
is the simplest possible `fallback_service(ServeDir::new(dist))`.
No source-file changes — just the esbuild outfile/outdir paths.
Rebuilt; verified asset filenames + sizes unchanged.
Refs #273.
Phase 1 of the backend/frontend code split (#273). Additive — no
existing code is touched; the legacy hive-c0re/assets, hive-ag3nt/
assets and hive-fr0nt/assets trees stay in place until the Rust
cutover later in this branch.
Layout:
frontend/package.json npm workspaces root
frontend/packages/shared/ @hive/shared
src/{base,terminal}.css + terminal.js (ES module)
src/index.js re-exports terminal.js
frontend/packages/dashboard/ @hive/dashboard
src/{index.html, app.js, dashboard.css} ported from hive-c0re/assets
build.mjs esbuild config → dist/
frontend/packages/agent/ @hive/agent
src/{index,stats,screen}.html + agent.css
+ {app,stats}.js ported from hive-ag3nt/assets
build.mjs esbuild config → dist/
Changes vs the existing assets:
- terminal.js is an ES module exporting { create, linkify } instead
of assigning to window.HiveTerminal. The dashboard / agent app.js
files re-expose them on window so the IIFE bodies keep working
unchanged through Phase 1; the global aliases can be dropped in a
follow-up once the IIFEs are unwrapped.
- marked is imported from the marked@4.3.0 npm package (replacing
the vendored hive-fr0nt/assets/marked.umd.js bundle).
- chart.js is imported from chart.js@4.4.4 (replacing the jsDelivr
CDN script tag on the per-agent stats page — page now works
offline / on operator machines without internet egress).
- dashboard.css and agent.css both gain @import lines at the top
that pull base.css + terminal.css from @hive/shared, replacing
the runtime string concatenation in serve_css.
- index.html / stats.html collapse from three / two script tags to
one type="module" tag pointing at the bundled output.
package-lock.json is intentionally omitted from this commit — npm
isn't available in the iris container yet (approval pending) and the
lockfile will land in the next commit on this branch once the
toolchain is in place. The PR will not be opened until it's there.
Phase 2 (nix derivations), Phase 3 (container plumbing + the
hyperhive.frontend.extraFiles option for per-agent layering), and
Phase 4 (Rust cutover to tower_http::ServeDir, delete hive-fr0nt
+ legacy assets dirs) land as follow-up commits on this same
branch.
