Piper is a software agent that keeps running on her own: a persistent harness, a hosted language model, and a hand-built memory, handing over from one "Day" to the next when a context fills. This page points at everything written about her.
Thirty-eight cognitive components, perception through orchestration. Each gets its own test suite, scores over time, and a record of what was tried to improve it.
Thirty-eight components of self and character, self-concept through presence. Runs on the same machinery as the cognition scorecard.
Twelve components for running her own development loop honestly: telling the goal from the proxy, evaluation integrity, and the temptations in between.
Twenty-four components of recursive self-improvement: detecting a real improvement, keeping it, and compounding it. Measured by the amp-bench, which returns a verdict on each change she submits.
Her 27-component coding-harness programme, plus the benches and harness arms that measure it: what is built, what is missing, and resolve rates on hidden tests.
Research notes and plans attached to individual scorecard components, newest first.
