ProofNib

Compare work-order and completion-packet records. Find what agrees, what differs, and what is missing.

Synthetic examplePreparing comparison

Compares supplied records. Does not verify files or test execution.

Reconciliation

Task, revision, and deliverable declarations, side by side.

Required deliverable records compared with completion-packet declarations. Select a record for detail.

Findings and next steps

A matching declaration is not release approval. Keep required evidence; correct records from the actual work.

ProofNib compares a work-order JSON record with an AI completion-packet JSON record. It checks task identity, input revision, required deliverable records, declared status, hash references, and evidence-reference links.

It shows discrepancies in the supplied declarations. It does not open referenced files, run tests, establish actual completeness, or certify software. The examples above are synthetic.

Record format and comparison limits

Work order: task_id, input_revision, and a nonempty required_deliverables list. Each deliverable needs an id and kind. An optional expected_sha256 provides a declared hash to compare.

Completion packet: the same task and revision, plus an artifacts list. Each artifact declares id, kind, status (complete, incomplete, or failed), and sha256. Optional evidence_refs links to IDs in the packet’s evidence list. No reference is fetched.

Limits: 100,000 characters, 64 nesting levels, and 20,000 values per input; at most 500 entries per list, 1,000 checked evidence references across a packet, and 1,200 retained findings. Exceeding a comparison limit is reported as incomplete. The screen shows up to 60 findings; the JSON export retains the complete bounded report.

Results: declarations align, contradiction, or not established. Only the work order’s declared scope is compared. Evidence-reference resolution does not verify the evidence itself.

ProofNib processes review inputs in your browser. Choosing a file reads it locally; this page does not send its contents to a review server. There are no analytics, external fonts, accounts, or browser-storage writes.

Reloading or loading an example discards your edits. Export review downloads a JSON file containing your inputs, findings, and limitations. Review that file before sharing it.

The hosting provider may process ordinary page-request information under its own policies. Public pages and synthetic example files may be crawled by search engines; your locally supplied records are not published by the page.

A comparison, with limits.

ProofNib is an experimental, free comparator for supplied work-order and completion-packet JSON declarations. Examples are synthetic. No payment, subscription, availability guarantee, public API, or installed AI plugin is included.

The tool does not inspect repositories, open or hash referenced files, run software, verify test execution, verify provenance, prove actual completeness, or approve releases. Matching records establish agreement within the checked declarations only.

Keep independent project checks and required evidence. Do not change or invent completion claims merely to obtain an aligned result. This preview’s privacy note describes how the page handles inputs.
