- config: channels (olx-bg/forums-local), pricing-rules (BGN, A/B/C/reject, drop ladder)
- brain: empty-seed capability contract + seeds README (memories never ship)
- toolchain: depo-sign.sh (ed25519, PEM+raw), validate-depo.sh (schema/files/cards/tools/
  secrets/sig gates -> writes VALIDATE), tool-registry.json
- install.sh: target-side verify (hash + ed25519 + layer files); install is phase 2

+template) covering the tested functions only. Never claim more than tested.

+ranges for that class/grade. Compliance checks price-guide claims before publish.
