What do a review freeze, a checkpoint and the handoff packet preserve?
A freeze is a digest-backed snapshot of the review state at a moment, with the version labels it applied to. A checkpoint is the whole review plus a SHA-256 digest that is verified before it restores. The handoff packet is thirty passive files with a manifest and checksums.
Why this review exists
Proposals move fast in the last week before a deadline, and a review that cannot say which version it applied to is not evidence of anything.
Three different jobs
A freeze answers what the review looked like when a version was settled. It stores a canonical snapshot and a digest, and it records the budget and narrative version labels it applied to, so a later change becomes visible as an amendment rather than disappearing.
A checkpoint answers how to get the review back. It is the whole review in a versioned envelope with a SHA-256 digest over its payload, and the parser refuses a file whose digest does not match rather than restoring part of it.
The packet answers what to hand to somebody else. Thirty files cover the review brief, the budget source and normalised rows, rollups, narrative source and paragraphs, extracted claims, ambiguous claims, evidence mappings, unmapped rows and claims, arithmetic and formula traces, indirect and match observations, amount, role and period conflicts, findings, decisions, the reviewer question list in two formats, freezes and amendments, a version comparison, the limitations page, a README, a manifest and SHA256SUMS.
What version control means here
Budget and narrative version labels are recorded as text on the review brief, and the sample uses Budget v7 and Narrative v11 both dated 3 September 2026. The tool does not manage your files; it records which ones the review applied to.
The source version comparison in the packet shows what those labels were at each freeze, which is how a reviewer three weeks later can tell whether a finding is still live.
Checksums detect changed bytes after export. They establish nothing about authorship, authority or correctness, and a digest is byte integrity and only byte integrity.
Practical sequence
- Freeze the review when a version is settled
- Record an amendment rather than editing a frozen state
- Download a checkpoint at the end of each session
- Export the packet for whoever needs the evidence
- Verify the checksums with your own tool
What remains outside the app
Grantweft performs arithmetic and textual cross-reference on user-supplied material. It does not write proposals or determine eligibility, allowability, accounting treatment, compliance, completeness, accuracy, submission readiness or funding outcome.
The private desk keeps exact source labels, stable budget row identities, paragraph-based claims, confirmed mappings, visible arithmetic, findings, human decisions, review freezes and passive handoff files connected without an account or remote application database.
