Evidence accrues at 03:14 in São Paulo. A KYC file. A counterparty's portal screenshot. An attestation. Fieldbook is the unit of work, the unit of transfer, and the unit of audit: a single .fieldbook file — a ZIP wrapping an AES-encrypted SQLite database, hash-chained oplog and audit, and the documents it speaks of.
Open it in the desktop app, mail it to a colleague, archive it for seven years — it remains a single verifiable object. Tread carefully; keep the field notes.
A nine-state lifecycle from collection through certification. Cryptographic attestation. Chinese-Wall isolation across firms inside one file. Every transition is logged.

SHA-256 document fingerprints + HMAC-signed attestation statements bound to verifier identity, document, time, and method.
HMAC for internal signing, PKCS7 for external, QES (Qualified Electronic Signature) for regulated jurisdictions.
Information barriers across firms inside the same file. Cross-wall access requires explicit authoriser approval, logged to audit.
Right-to-erasure, data-subject requests, cross-border transfer logging — implemented at the format level, not bolted on.
Policy-driven row filtering. The same file shown to different users yields different rows — enforced by the engine, not by the UI.
Obligations extracted by Redline Ledger flow into Fieldbook for evidence collection and auto-satisfaction tracking.
