Self-hosted variable fonts (Overpass/Overpass Mono, OFL-licensed) --
no CDN dependency for the app to render correctly. Dark is the literal
default in tokens.css (:root defines it directly; light is the
override via both prefers-color-scheme and an explicit data-theme),
not a retrofit. Severity tokens collapse OTel's seven severities to
five visual tiers (severity.ts); their translucent -bg variants and
light-mode warn's base color are already tuned for WCAG AA contrast
against an opaque surface, not just the plain page background --
verified with real axe-core runs during the accessibility pass, see
docs/design-system.md.
theme.svelte.ts/density.svelte.ts persist to localStorage and expose
getter/setter functions wrapping module-level $state (Svelte 5's
shared-state-module pattern -- a directly exported $state doesn't
preserve reactivity across modules). app.html's inline script applies
both before first paint to avoid a flash of the wrong theme/density.
End-to-end log pipeline for Linux hosts, per /docs/architecture.md:
- proto: shared gRPC contract (agent <-> ingest), Go bindings checked in
- agent: Rust, musl-targeted, journald/file sourcing, RFC5424 parser,
mTLS gRPC client, no required config for the common case
- ingest: Go, single binary with --mode server|consumer|all; gRPC front
end forwards to Redpanda unchanged, consumer normalizes and
batch-writes to ClickHouse with at-least-once delivery
- storage: ClickHouse schema + a plain SQL-file migration runner
- api: minimal SELECT-only query endpoint, plain REST (not gRPC+gateway
yet -- see api/README.md)
- web: SvelteKit static SPA, one query page
- transport: Redpanda compose + topic provisioning
- cli: sentryctl ping stub
- hack/dev-certs: throwaway CA + cert generation for local mTLS
- root docker-compose.yml + docs/phase-0-runbook.md tie it together
Not yet run end-to-end against real Docker/ClickHouse/Redpanda -- see the
runbook's caveats section before relying on this working as-is.
