StatusBuilt inside a working brokerage in MT, ID, WA, WY and ND. Live today: the file, the record, permissions, document storage. In build, in this order: forms, signing, document reading.

Caught at upload, not by a reviewer days later.

FlaggedOwner’s Property Disclosure: seller initials missing on pages 3 and 5 of 7. Not ready to submit.

SignBlock is designed to take each upload apart like a reviewer: every document onto its requirement, and anything that would get the file rejected named by page.

5 of 7 filed, 1 flagged, 1 open. Not ready to submit. Everything else checks out. The copy of the Buy-Sell is held, not filed twice. Page 14 is kept in Unfiled until a person says what it is.

Signed and filed in the same second.

When the last signature lands, the executed copy files itself back to its requirement. No one downloads it, renames it or drags it onto the checklist. When a signing email fails, the file says who, when, and what to do next.

The Buy-Sell Agreement, sent to three signers on two sides, passes three signature lines: Desmond Hollister, buyer; Evan Lockhart, seller; Maren Lockhart, seller, last to sign. The executed copy drops into requirement 3 on the checklist, beside the Listing Agreement and the Agency Disclosure, at 9:14:08 AM MDT, the same second as the last signature.ABuy-Sell Agreement3 signers, 2 sidesDesmond HollisterBuyerEvan LockhartSellerMaren LockhartSeller, last to signBSigned, 3 of 3Both sidesCExecuted copyTo requirement 31ListingAgreementFILED2AgencyDisclosureFILED3Buy-SellAgreementFILED9:14:08 AM MDTsame second as thelast signature

Who did it, under whose authority, to the second.

Every action on a file writes one entry to an append-only record: the real person, the authority they acted under, what they did, and the time with its zone. Refused attempts are written too. If anyone alters an entry, it stops verifying. This part runs today.

Fig. 3. Example file. The record itself runs today, with sign-in, permissions and document storage. Entries made by document reading and signing are illustrative until those parts ship.

Machines propose. People confirm.

Each value read from a document arrives as a proposal, led back to its source. Five values never accept themselves, at any confidence: the purchase price, the closing date, the earnest money, the legal description and the party names. They wait above the file for a person.

Fig. 4. Example file. Each proposal is led back to the line it was read from and held above its place on the file until a person confirms it. P marks a proposal. Document reading is in build; illustrative.

Across this page, solid marks what a person did. Dashed marks what document reading did or proposed, or what still waits on a person.
