Closes #3410. `ApiErrorPanel` renders a ProblemDetails (RFC 9457) error nicely, with a copy button so the full text can be pasted straight into a bug report. No truncation of `detail` — on the #3363 incident that motivated this issue, that string was the entire diagnosis. `readApiError`/`problemMessage`/`ProblemDetails` are promoted out of credentials.js's original `readErrorBody` into `@hive/shared/api-error.js` (comment rewritten: the RFC 9457 rework has already landed everywhere except swarm-controller's status route, #3412 in flight, so the raw-text fallback is a compat shim for that one gap, not a general transition). credentials.js's 4 call sites switch to the shared reader (kept as one-line messages there, its result slots are single-line aria-live regions, not a panel context). Wired ApiErrorPanel into OverviewPage.tsx (the issue's own worked example) and CreateAgentPage.tsx (second real call site). Not built on <hive-warn> despite matching its visual language — that custom element's CSS-as-text import only works under a build with loader: 'text' for .css (dashboard's), and silently renders unstyled under swarm-ui's default css loader (filed separately as #3415). ApiErrorPanel is a self-contained light-DOM component instead, per mara's own suggestion to keep it independent of the old UI's shapes. |

hyperhive frontend
npm workspaces project for the hyperhive browser-facing assets:
packages/shared/— shared modules used by both surfaces (terminal pane, Catppuccin palette + body typography).packages/dashboard/— the hive-c0re dashboard SPA.packages/agent/— the per-container web UI (default agent page, stats, screen).
Build
npm install # one-off; uses the checked-in package-lock.json
npm run build # builds every workspace into packages/*/dist/
The Rust binaries serve packages/dashboard/dist/ and
packages/agent/dist/ via tower_http::ServeDir at runtime; the
build derivation is wired up in nix/modules/frontend.nix. Per-agent
additions are layered on top of the default agent dist via the
hyperhive.frontend.extraFiles option in agent.nix.
Why npm + esbuild
- Hermetic: dependencies vendored via the checked-in lockfile;
buildNpmPackagein nix uses it as the source-of-truth so the output is reproducible without network access at build time. - esbuild: vanilla-JS bundler, no framework runtime overhead.
Each workspace's
build.mjsis ~30 lines. - Single-PR migration: see issue #273 for the design proposal and the four-commit shape (npm scaffold → nix derivations → container plumbing → Rust cutover).
