Cases and workpapers
The professional workflow layer: cases, workpapers, issue tracking, reviewer sign-off, and an immutable final pack at the end of it.
What it does
Nine standard folders
Engagement through final pack, in the order a reviewer expects to find them.
9 standard workpaper folders.
Reviewer sign-off
Issues are tracked to closure and the sign-off is recorded, so the review is evidenced rather than remembered.
Immutable final packs
Once signed off, the pack is fixed. What the client received is what can be produced later.
Monthly cryptographic audit proofs with SHA-256 verification.
Reconstruct the answer exactly as it stood.
Every figure in the pack traces to the calculator version that produced it and the corpus release it was cited against. A query in eighteen months is a lookup, not an investigation.
Answers are pinned to a corpus release, model version, and calculator version, so any answer can be reproduced later.
