echd — Echo on Encore · E6
The Surface — Dashboard & Management
The platform is visible, and the visibility is honest — every answer says which plane produced it and how fresh it is.
echd speaks in the present tense over a build ladder. Every module, verb, key, and port named on this page is real; the composition into one standing platform is the vision the ladder builds.
The chapter
the build register: docs/echdash/eda.roadmap.mdThe platform is visible, and the visibility is honest. echdash — the owned dashboard on :8891 — replaces the hosted SPA with a surface that tells the truth the stock page cannot: live status with degraded states rendered rather than masked, requests with payloads verbatim in code blocks, a catalog that renders while the app is down, logs that mark their gaps instead of splicing them. The raw tab is the proof of the verbatim law: what the daemon said is what the page shows.
Topology is not a drawing; it is a relation held by a system. A Go registry mints branded names once and holds edge stores under the EdgeStore law of E2 — the declared graph (what status.meta promises) beside the observed one (what the traces witnessed), laid out by a hand-rolled layered SVG with no graph dependency. Every response is stamped plane + as_of: the plane ladder answers from the live wire when it can, from the read-only database when the wire is down, from the vault for history, from the ech proxy for the MCP census — and from the last-known cache when everything else is quiet, saying so. The management plane completes the surface: the panel, sessions in view, the census honest about which upstreams stand. Degradation here is a CAP stance — the surface chooses availability and stamps its staleness.
The plane ladder
hover a rungplane names which rung produced the response; as_of says how fresh it is. Clocks never silently mix: a vault answer wears plane:"vault", a cached one says so, and the reader always knows which truth they hold.ech proxy answers for the MCP census; and the last-known cache answers when all else is quiet. Each family degrades down its own ladder — never sideways into another's.{subject,object}, both ends gated. The declared graph comes from status.meta; the observed one from witnessed calls — and the diff between them is the dashboard's sharpest instrument: dead wiring and drift, visible.Hover or focus a part to read it; click to pin. Without scripting, all five read in sequence.
