04 · How it works

Upload to signed package.

Bring the buyer’s tender documents. Steinlog turns them into a priced, gated, provable submission package — and you sign and submit.

The readiness gate

One “can we submit / what’s blocking” oracle, each gap tied to its clause and routed to an owner. It computes the per-tender signature tier — AdES by default, QES only when the notice demands it.

Ingest the tender (Word, Excel, PDF)
Clause-anchored requirements + bill of quantities
Price it together — human-owned numbers
The gate computes what blocks submission
Package: GAEB X84 / .ATH, ESPD, ASiC-E + timestamp
You sign and submit; we ingest the receipt

NOT YET 3 items block submission

✕Signature tier: QES required (SWZ §7.2) — current: AdES

✕Per-partner ESPD missing for Partner B

✕Bill of quantities: 2 lines unpriced

✓Addendum 2 acknowledged

✓ASiC-E manifest ready to seal

AI proposes, humans own

The AI drafts the plan, the prices, the documents — but every binding act is a human event, enforced at the data layer. It round-trips the authority’s own files; it never invents a fresh one.

Build the first provable bid with us.

We’re onboarding a handful of Polish and German construction firms as design partners. Bring a live tender; we’ll build the loop around it.
