Check your own evidence before it goes in the bid
The problem
Evidence fails a bid in three quiet ways: a certificate that expired between renewal and lodgement, one held by a related entity rather than the tendering one, and a level below what the pack demands. All three are usually found by the buyer, not by the bidder.
Documents arriving from subcontractors and brokers by email carry your name into the submission, and nobody checks the file itself because there is no obvious way to.
How Stipple helps
Run each document through a forensic check before it goes in: tampering signals, provenance and producer metadata, and the dates the document itself carries.
Then check the assembled pack against the required-document list in one call. Each file is classified into its slot and anything missing is reported as missing, rather than silently scored around.
The call
curl -X POST "https://www.stipple.sh/v1/check-pack?requirements=insurance_certificate&requirements=licence" \
-F "files=@insurance.pdf" -F "files=@licence.pdf"
# -> { "complete": false, "missing": [...], "slots": [...],
# "documents": [...], "unmatched_documents": [] }Evidence problems surface while you can still fix them, instead of in a clarification request from the buyer.
What the result looks like
A clean forensic result means no tampering signal was found. It is not a statement that the certificate is valid, that the insurer issued it, or that the buyer will accept it.
Pack completeness is measured against the checklist you supply. It cannot know a requirement you did not give it.
None of this is a compliance determination. Compliance is what the evaluation panel decides.
How the corpus was built, what was caught, and what the method does not prove.
Questions
- Can you confirm an insurance certificate is real?
- We report what the file shows: tampering signals, provenance and producer metadata, and the dates on the document. Confirming a policy is in force is something only the insurer or a broker can do. The forensic check catches an altered document, not a convincing fabrication issued from nowhere.
- What happens if a document is missing from the pack?
- It is reported as missing by name. An incomplete pack and a clean pack are different answers, and collapsing them would be the most dangerous thing this check could do.
