How?
Add the exact original files for this part of the record. Keep them unchanged; a different export or edit has a different fingerprint.

Engineering handover
Keep the existing commissioning test sheets, measurement exports and handover record as a dated version.
Keep the existing commissioning test sheets, measurement exports and handover record as a dated version. Keep your original source records together, then date the exact files. It does not prove a test occurred, measurement accuracy, system performance, client acknowledgment or contractual acceptance.
Your photos and files stay on your device, so keep them.

Now keep it safe: three things
- Keep your photos and files unedited. The receipt only matches the originals. Put them in an album such as “My records”.
- Save this receipt to your camera roll.
Keep the receipt file too. The image is a handy copy; checking needs the file.
- Email it to yourself.Email it to myself
Your mail app opens a draft. Attach your receipt image and receipt file. Don’t attach your photos or documents. Timevolt does not send it or know whether it was sent.
Your record, one step at a time.
Your photos and files stay on your device, so keep them.

How to keep notes that hold up
Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.
- Write it down straight away, on paper or in the box on a step.
- Put the date, time and place at the top, and who you spoke to.
- Use their words where you can; separate what you saw from what you were told.
- Sign or initial a paper note, photograph it and add the photo.
- Never edit an old note. Add a new dated entry when something changes. A device save time is not independent time evidence or proof of event order.
Acceptance test results at handover
Acceptance test results at handover
01 · Keep the exact files
Keep the original files for acceptance test results at handover. Include any existing photos, signed records and source-system exports.
Records to keep: Commissioning test sheets and measurement exports, acknowledged by client
Acceptance test results at handover
02 · Date the file’s code
Your device fingerprints the selected file or manifest. Dated follows an independent timestamp; Permanent follows Bitcoin anchoring.
An independent time, tied to the exact bytes.

Keep the original files and complete receipt separately, alongside any existing venue, signature and workflow records.
Keep the originals too. A changed or compressed copy has a different fingerprint.

Compare handover records against the intended dates
An owner and builder disputed delays at an energy plant. Real handover data showed work lagged behind plans. The court used it to assess delay and upheld the owner's right to end the deal, among broader mixed claims.

Proves / Doesn’t prove
Proves
A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.
Doesn’t prove
It does not prove a test occurred, measurement accuracy, system performance, client acknowledgment or contractual acceptance.
It does not prove a test occurred, measurement accuracy, system performance, client acknowledgment or contractual acceptance.
These are the bounds of a completed proof. The local tester does not establish any time. The chosen court, scheme or regulator decides what to accept.
Questions, answered plainly.
Your file stays on your device. During normal receipt creation, your device sends a randomized code made from its fingerprint, plus encrypted recovery data. It doesn't send the plain fingerprint or the random value that opens the code. Keep the original file and the complete receipt for checking. Privacy Policy.
Does a dated report establish client acceptance?
No. The software appeal illustrates contract-specific milestones and remedies; a receipt does not supply acceptance.
