can turn a winning number into a loss
A missed exclusion, warranty gap, or bad total walks straight into buyout.
[ What it catches ]
Four traps.
Caught before close.
Each catch is tied to the document and page that proves it—so the estimator can verify it, price it, and approve the move.
TRAP 01WHOLE BID
Mandatory site visit
Spec 01 11 00 §1.8 · page 3
Absent from the invitation email. Non-attendance disqualifies the bid.
TRAP 02SCOPE GAP
Spec vs drawing conflict
Chiller schedule · drawing M-401
Spec calls for 350 tons. The drawing schedule calls for 400. RFI drafted before pricing.
TRAP 03+$42K / +$27.5K
Excluded startup + short warranty
Vendor quote · fine print
Startup labor excluded. One-year warranty offered against a two-year requirement.
TRAP 04Δ $500,000
Total ≠ itemized sum
Vendor quote · total check
The stated grand total and the sum of its line items differ by half a million dollars.
From the Riverside Office Tower demo scenario. Names, companies, and prices are fictional.

Human gate · You submitControl is architecture
Three rules that
do not move.
This is how an estimating team lets AI near the bid without giving it authority it should never have.
✓
Nothing
auto-sends.
The mail connector refuses to release anything unless the request cites a recorded, approved decision.
≠
Money is code,
not a model.
Every extension, sum, reconciliation, and allowance uses deterministic integer-cent calculations.
⌁
The agent never
sees your keys.
Capability-scoped connectors hold credentials, enforce access, and write every allowed or denied request to the audit log.
[ After the bid goes out ]
The bid doesn’t end when you submit it.
Neither does ArosBid.

Autonomy grows.
The approval gate never moves.
