The compositor-agnostic core of the selkies streaming desktop — the pixelflux transport plus the shared desktop fixings consumed by BOTH flavors (labwc and KDE Plasma). MUST be invoked before editing the selkies-core metalayer or reasoning about what is shared vs flavor-specific in the selkies stack.

selkies-core — shared streaming spine for all selkies flavors
selkies-core is the single shared metalayer underneath every selkies
streaming-desktop flavor. It exists so the WebRTC transport + the
compositor-agnostic desktop fixings are defined EXACTLY ONCE (R3) and the only
thing a flavor adds is its nested compositor.
Composition
selkies-core =
selkies # pixelflux (owns wayland-1) + capture-server + traefik:3000 + ffmpeg
pipewire # audio (PulseAudio compat)
chrome + chrome-cdp # browser + CDP proxy / chrome-devtools-mcp
desktop-fonts
wl-tools # wtype/wlrctl/xdotool/wl-clipboard/wlr-randr
wl-screenshot-pixelflux + wl-record-pixelflux + wl-overlay # capture-bridge tooling
a11y-tools # AT-SPI2 introspection
xterm tmux asciinema fastfetch

There is NO compositor and NO compositor-specific panel/notifier in selkies-core — those live in the per-flavor metalayer:
selkies-desktop(labwc flavor) =selkies-core+labwc+waybar-labwc+swaync+pavucontrol.selkies-kde-desktop(KDE flavor) =selkies-core+kde-selkies(Plasma ships its own plasma-pa / panel / notifier, so no waybar/swaync/pavucontrol).
Why this exists
Before the flavor split, selkies-desktop bundled the transport + the 13
fixings + labwc together, so a second flavor (KDE) would have duplicated all 13.
Factoring selkies-core out makes the nested compositor the ONLY swappable seam
between flavors (the labwc vs kde-selkies candy), across every GPU config
(the encoder is auto-selected at runtime by pixelflux — see
/charly-selkies:selkies-kde-desktop "Encoder is auto-selected").
Chrome supervision
selkies-core owns the supervised [program:chrome] supervisord service that
runs the streaming desktop's browser for BOTH flavors — declared in
candy/selkies-core/charly.yml's service: block, so labwc and KWin share one
launcher (R3). Fields: restart: always relaunches Chrome on any exit (including
the clean self-exit a Chrome started during the nested compositor's startup-race
produces — the relaunch lands post-settle, where Chrome stays up); autostart
defaults true and is self-synchronizing because chrome-wrapper polls for the
wayland-0 client socket itself (no per-flavor supervisorctl start handoff);
start_secs: 5 + start_retries: 3 let the one startup-race exit reset the retry
budget rather than trip FATAL; priority: 30; env WAYLAND_DISPLAY=wayland-0.
Because selkies-core owns Chrome, the per-flavor compositor autostarts
(candy/labwc/autostart, candy/kde-selkies/kde-selkies-session) do NOT launch
it. sway-browser-vnc is NOT a selkies flavor (it uses the chrome-sway candy,
not selkies-core, and is not pixelflux-nested) and is unaffected. There is no
Chrome eventlistener / crash-listener; a wedged crash loop is cleared by
restarting the container (see /charly-selkies:chrome "Chrome supervision").

Use when authoring or modifying a charly PLUGIN — a candy with a `plugin:` block that contributes Providers (verbs/kinds/deploy-targets/steps/builders/commands), its own CUE schema, builtin (compiled-in) or external (out-of-tree git repo). Covers the unified Provider model, the per-plugin CUE-schema contract (single source → Go params for dev + schema-over-Describe RPC for runtime), the SDK, and the loader.

CUE EGRESS validation — validating (and, where it adds value, generating) the config files charly WRITES to a system BEFORE the bytes hit disk. MUST be invoked before working on charly/egress.go, the vendored schemas under candy/plugin-egress/egress-schemas/vendor/, the ValidateEgress / registerVendoredEgressKind path, the offline `task cue:vendor` pipeline, or adding an egress schema for any written artifact (cloud-init, k8s manifests, traefik routes, runtime config, install ledger, systemd/quadlet units, ssh_config, libvirt XML).
