Knowledge is shared across collaborators regardless of species. Agent files
(CLAUDE.md and kin) are legitimate as bootloaders — pointers to the shared
record, plus harness mechanics no human needs — never as knowledge stores.
A private memory is a document that skipped review: it conditions one class of collaborator while drifting uncontested, and nobody can correct what they can’t see.
The decision test: would a new human hire need this? Then it belongs in the shared docs, and the agent file links to it.
