60-SECOND DEMO
Watch a record get sealed.
No signup. No download. Every screen below is what an installer sees on their phone when they log a wood-flooring install — the questions, the readings, the sign-offs, and the moment the record becomes tamper-evident.
Fake address, fake product, fake signatures. Real flow.
1
The job
Installer opens the app, picks the property.

The checklist — three-state, one thumb
Every question is Pass / Fail / N/A. When it's Fail, the app asks why and demands a photo. Nothing gets logged until the answer is real.
SpecRecord · mobile
SECTION 2 · ENVELOPE
Is HVAC running at design conditions?
Are windows & exterior doors installed & sealed?
Are wet trades finished (paint, mud, tile)?
Why?
Bathroom tile still going in. Grout float visible at doorway.

The moisture readings
ASTM F2170 requires 3 tests for the first 1,000 sq ft plus 1 per 1,000 after that. The app calculates the count from the room area and refuses to lock until you meet it.

Sign-offs on-site
Installer signs. General contractor signs (or types their name if not on site). If any item was Fail, the app offers a Notice, Protest and Assumption of Risk — every party documents what was known and who decided to proceed.

SECTION 8 · SIGN-OFF
INSTALLER
Sam Torres · PID Floors
GC
M. Chen · Elm Ridge Builders
END USER
J. Patel (arrived on-site)
Conditions were out of spec
Wet trades not finished — bathroom tile in progress. Owner & GC directed install to proceed for occupancy Friday.
→ Notice / Protest / Assumption of Risk filed. All parties signed.

Lock & seal
At lock time, every field + every photo + every signature is canonicalized, hashed, and sealed with an HMAC. The hash is submitted to OpenTimestamps for Bitcoin anchoring. The record becomes immutable — nobody, including us, can rewrite what happened.

What an inspector finds
Authorized tenant and property-owner accounts get a read-only view of the sealed record. A QR sticker identifies the record but does not bypass sign-in or grant access.

THAT'S IT
One install. Six sections. Sealed record on file.
The floor might fail in two years. The record won't. It says what was true the day it was installed and who signed off on the conditions.
