Observer — watch a machine's state
The Observer is how you look at a machine. Every transition a machine records lands on its append-only entangled-state chain, and the Observer is the window onto it — a block-explorer that shows the state, live, and lets anyone verify the whole history for themselves.
One chain at a time
The Observer never mixes chains. You choose a scope and see exactly that:
Foundation
The machine's foundation scope — its base chain, on its own.
Yours
Your entangled state — only your rows, never intermixed with the foundation.
Another machine
Any machine you have read access to — public state is browsable by anyone.
Within a scope, transitions are grouped into lenses by what they are — contract transitions, per-application sections — so one busy chain reads as several clean feeds. The append-only rule is respected all the way through: you can save views and local labels, but never edit history.
Live, on the Zeqond
The feed is live — transitions stream in as they happen, and the activity indicator pulses on the 0.777 s Zeqond, so you're watching the machine tick on the framework's own heartbeat. Activity is bucketed per Zeqond (a rolling window of the last several thousand ticks), giving you a density view of when a machine was busy — every Zeqond tracked, the buckets just for display.
Verify the history yourself
This is the part that matters. The Observer isn't asking you to trust what it shows — it hands you a command to check the whole chain independently, offline:
zeq chain verify # VDF spine · elapsed Zeqonds · hash links · Ed25519 · zero secrets
That re-walks the entire history: the Proof-of-Elapsed-Zeqonds seal spine, the hash links between entries, and the Ed25519 signatures — with no secrets required. You can also copy the current state hash to pin exactly what you're looking at. Browsing the chain and proving the chain are the same activity here.
