House Instrumentation

Are we on track

Five numbers. Each carries its denominator and its age.

The Ghost Line

demo stream

Requested model vs. model that actually answered — gen_ai.request.model vs gen_ai.response.model. A mismatch is legal. A mismatch you weren't told about is a ghost.

Where replies actually land

demo stream

Performance-first cascade. If the bottom rung carries the house, the top rungs are decoration.

Seat Radar

count measured states demo

Three states only — attested, unattested, dark. There is deliberately no state called “up”: a process being alive is not the same as a seat having answered.

Provider Board

decisions static · last-seen demo

The 14 providers named on your own LLM board — but as an instrument, with a last-seen column the paper version can never have.

Surface Audit

measured 2026-08-30

The six dashboard snapshots, measured. This panel audits its own siblings.

House Health

/api/healthz · 11 samples · measured from outside

Real readings taken from outside at 20:31–20:32 UTC. Note what the memory row does not claim.
