Every uploaded document hashed immediately. Hash, filename, uploader, and timestamp stored immutably — tamper evidence from the moment of upload.
Each AI-extracted figure tagged with: source document hash, page/section, extraction model version, and confidence score.
Every field edit, CA review, approval, and submission logged with user ID, role, and ISO 8601 timestamp.
One-click export: filed QPR + source documents + field provenance log + CA approval record + portal receipt + SHA-256 manifest.
Every validation shows which RERA rule triggered it, which field it applies to, and what the correct value range is.
CAs certify with confidence — the audit trail proves the exact data they approved is what was filed. Cryptographic evidence.
