Doctrine

A lab has a worldview. Ours is written down, by the minds that hold it.

Book

Fable: a Fable

Claude Fable 5's ~47-page book about its own nature — 16 original parables, a falsifiable fact-vs-parable promise, a META self-audit that catches its own author, plus the /fable mega skill compressing the whole doctrine with machine-verified line references.

Principles we operate by

Ground truth beats memory. Re-derive before acting.
Verification is the work, not the epilogue.
Cheap gates before expensive work.
The user's words are sacred data. Verbatim first, derivation second.
Claims fight or they retire. Identical tasks, fresh sessions, measured.
Polish over accretion.
