Adds a browser-local (localStorage only, no backend field) toggle in
the per-agent overflow menu's new settings section: whether otherwise-
collapsed <details> rows in the live terminal (long tool-results,
Write/Edit diffs, ...) default open. Message-bearing rows that already
default open (send/ask/answer/recv) are unaffected either way.
The shared terminal factory (frontend/packages/shared/src/terminal/terminal.js)
gains an optional expandDetails option (boolean or zero-arg function),
read live on every details()/detailsDiff() call rather than captured
once, so flipping the toggle mid-session applies to the next rendered
row without a reload. Unused by the dashboard's own terminal pane, so
its default-closed behaviour is unchanged.
Closes#2961.
Both mdNode implementations (agent UI app.js, dashboard common.js)
assigned marked.parse() output straight to innerHTML with no
sanitizer. marked v5+ dropped its built-in sanitize option, and there
was no DOMPurify anywhere in frontend/, so markdown containing raw
HTML/script tags rendered live in the browser.
Both sinks receive untrusted input in practice: the agent UI's mdNode
renders recv tool_result bodies, assistant prose, and send/ask/answer
payloads sourced from peer agents and matrix-relayed messages (the
documented prompt-injection adversary); the dashboard's mdNode renders
agent-authored .md files served verbatim by GET /api/state-file
(the endpoint validates path, not content). Since the per-agent UI and
dashboard are same-origin behind the gateway with operator-authority
endpoints (approve/spawn/rebuild/destroy/answer-question), injected
script would run with the operator's session.
Fix: DOMPurify.sanitize() the marked.parse() output at both sinks
before assigning to innerHTML. Added dompurify as a dependency to
both the agent and dashboard npm workspaces, recomputed npmDepsHash
in nix/frontend.nix for the updated lockfile. Also corrected
docs/web-ui/shape.md, which claimed the markdown-rendering path was
XSS-safe by construction the same way the text-node-based linkify
path is — it isn't; it's safe because it's sanitized.
CSP hardening for the dashboard (no unsafe-inline) is a separate,
larger backend change (response headers in hive-c0re) and is left as
a fast-follow rather than folded into this fix.
After the SW4RM and Y3R C4LL extractions from tabs.js (PRs merged
earlier), several docs still pointed at `assets/tabs.js::fn`. Update
them to the authoritative module:
- dashboard.md: renderContainers, buildAgentTree → swarm.js
renderApprovals → call.js
renderPeerHives → swarm.js
- shape.md: generic "tabs.js render function" → "domain module"
- conventions.md: clarify async-form listener lives in tabs.js (dashboard)
AND app.js (per-agent UI)
- .prettierrc: proseWrap=preserve (no prose reflow)
- .prettierignore: exclude hivectl-cli.md (auto-generated) + 11 docs
with multi-line list-item continuations prettier would strip to col 0
(CommonMark limitation in prettier's list handling)
- format 16 markdown files: cosmetic only (*→_, table alignment,
heading normalisation) — verified no broken continuations, idempotent
docs/web-ui.md (1315 lines) split into three sub-files:
- docs/web-ui/shape.md — shared SPA skeleton, SSE multiplexing,
Worker-death self-heal, terminal pane, listener bind, relative
paths, atomic repaint, side panel
- docs/web-ui/dashboard.md — SW4RM/Y3R/SYST3M/SCH3DUL3S/S3TT1NGS
tabs, container row, topology tree, selection bar, approval card,
dashboard endpoints + event channel
- docs/web-ui/agent.md — header, terminal, composer, inbox, live
view, slash commands, per-agent endpoints, stats page
docs/web-ui.md replaced with a thin index linking all three.
Section anchors in docs (gateway.md, gotchas.md), Rust doc comments
(hive-ag3nt/src/web_ui.rs), and nix/templates/weston-vnc.nix updated
to point at the correct sub-file. README and CLAUDE.md file-map
updated with sub-file links. Inline // comments in frontend source
left unchanged (they reference the index which redirects to the right
sub-file).
