Evidence & timeline

The whole record, read and accountable.

A permanent, cited timeline

Every event carries its date and a verbatim quote from the page it came from, verified in code. The chronology renders from events your team confirmed - never free-written prose.

Record health, stated plainly

Unreadable files, poor scans and uncertain dating are flagged, never papered over. “All documents read” is an earned claim here.

Record health
153 documents read, OCR'd and indexed
2 poor scans flagged for manual review
0 unreadable files · 0 uncertain dates

Flagged documents are excluded from confidence claims until resolved.

Every citation opens the page

The evidence viewer opens the actual page image with the cited words highlighted. Reviewers check evidence in seconds.

The Contractor is instructed to place an order

The cited words, highlighted on the actual page image - not a reference, the document.

Delay analysis

The days come from the network, never from a model.

A CPM engine, not an opinion

The Primavera schedule is reparsed and the critical path recomputed deterministically - calendars, lags, constraints and all. Schedule anomalies are reported, not silently trusted.

Delay analysis
CPM · forward/backward pass
A1020 Substructure
A1080 Light Wall procurement
A1140 Envelope close-in
A1200 Fit-out zone C

Critical path in accent. Float, lags and calendars computed by code - never by a model.

Causation you can defend

Events link to the activities they hit; impact days come from the network. Where linkage cannot be established, the claim says so.

Linkage · event to impact
02 Feb 2006 · late instructionA1080 Light Wall procurementcritical path · days computed

If a linkage cannot be established, the claim says so - it never bridges the gap with prose.

Claim drafting

Drafts that carry their own proof.

Cited by construction, verified independently

The drafter cannot emit a factual sentence without evidence - the schema rejects it. A separate verifier checks every citation against its source.

The export gate

Contradicted or uncited sentences block export - in code, not in a prompt. Weak support goes to your QA queue for a named reviewer; contradictions can never be approved away.

“The instruction was issued in good time.” contradicted

The gate is enforced in code. It cannot be talked out of refusing.

A real document at the end

A .docx with real Word footnotes, each resolving to a document and page in the record.

Answers with receipts

Every factual sentence in an answer carries a verbatim quote, verified in code before it renders as cited. What the record does not say, datum says it does not say.
