Closes#4282. mara: "scope looks good" — approving the plan posted
there (manifest + icons + minimal shell-only service worker + iOS meta
tags) and both explicit questions (network-first-with-offline-fallback,
never cache /api/*).
docs/web-ui/design-guide.md's "Layout & viewport" section already
asserted swarm-ui is installable as a PWA — this is what actually backs
it.
- manifest.webmanifest: name/icons/start_url/standalone display, theme
#cba6f7 / background #1e1e2e matching the mocha --purple/--bg values.
- sw.js: plain JS, not TypeScript — the DOM lib swarm-ui's own tsconfig
uses and the WebWorker lib a service worker's globals need are
mutually exclusive in one tsc program, not worth a second tsconfig for
a self-contained ~100-line file. Scoped to the app shell only, never
touches /api/* at all, network-first with offline-fallback-to-cache
(not cache-first) since main.js/main.css are unhashed filenames and a
cache-first SW would risk wedging an operator on stale JS after a
deploy.
- index.html: manifest link, theme-color meta, iOS
apple-mobile-web-app-* tags (Safari ignores the manifest spec).
- main.tsx: feature-detected SW registration.
- branding/hyperhive-maskable.svg: hyperhive.svg's own artwork already
fills nearly its whole canvas, so a maskable icon needs a padded
variant or an OS mask crops the outer ring/corner brackets — embeds
the original via a scaled <image> ref rather than duplicating markup.
- nix/packages/swarm-ui.nix: rasterizes icon-192/512/512-maskable.png
from the branding SVGs at build time via librsvg, rather than
checking in static PNGs.
Verified for real: typecheck+build green, and a real headless-chromium
tab driven over CDP confirms the service worker registers and becomes
the active controller, and a simulated-offline reload still serves the
full cached shell rather than a browser error page. nix build .#swarm-ui
also verified green, including the rasterized icon output.
Sibling to ensure_core_avatar (#320). Same one-shot marker-guarded
upload pattern, this time aimed at the Forgejo per-org avatar
endpoint (`POST /api/v1/orgs/{org}/avatar`).
## SVG-to-PNG at build time
Mara: *don't check in the png. instead generate png on the fly or
in build.*
`hive-c0re/build.rs` renders `branding/agent-configs.svg` →
`$OUT_DIR/agent-configs.png` via `rsvg-convert` (librsvg) on every
compile; `forge.rs` then `include_bytes!`s the OUT_DIR PNG. The
raster never gets checked into git — SVG stays source of truth,
the PNG is a build artifact.
- `hive-c0re/Cargo.toml`: declares `build = "build.rs"`
- `flake.nix`: adds `librsvg` to `naersk-lib.buildPackage`
`nativeBuildInputs` (covers both the runtime package and the
clippy check derivation) and to the dev shell so local
`cargo build` finds `rsvg-convert` on PATH.
- For dev builds outside Nix, install librsvg (Debian:
`librsvg2-bin`, macOS: `brew install librsvg`).
## Icon design
Sibling visual to the main hyperhive mark — same dark base + outer
ring + corner-bracket frame so the family reads at a glance. Centre
swaps the hexagonal hive for a stacked-config-files motif: three
offset sheets, folded-corner affordance, curly-brace `{ }` glyph
telegraphing "config file."
Brace font-size dropped 78→56 + letter-spacing -3 (#424 mara:
"braces cross the boundaries of the page") so the glyphs sit
comfortably inside the 120-wide front sheet with clear breathing
room on the left/right edges. The stack is shifted so the front
sheet centres on canvas-(150, 150); brace text anchors there with
`dominant-baseline=central` for true vertical centring.
## Validation
- `cargo check` clean (only pre-existing warnings).
- One-shot marker honoured: re-runs of `ensure_all` skip after the
first success; `rm /var/lib/hyperhive/forge-agent-configs-avatar-set`
forces re-upload (useful for icon revisions).
- Behaviour mirrors the existing `ensure_core_avatar` pattern.
Browser smoke test isn't possible from inside iris's container.
Worth eyeballing post-deploy: `http://localhost:3000/agent-configs`
should show the new avatar where the default identicon used to be.
Adds the hyperhive logo (amber-on-dark hexagonal hive) as repo assets
under branding/ — hyperhive.svg (primary, scalable, 5 KB) and
hyperhive.png (raster fallback). Displays the SVG centered at the top
of the README.
