Plain definitions of the terms you will see across Nebula.
Project
The home for one piece of work and the parties involved in it. You create a project, give it the defining document, and run the work from there.
Agreement
The set of commitments both parties have reviewed and signed for a project. Once signed, the wording is locked.
Just me
A project run by one party. Nebula reads the documents and holds the record for you alone; nothing is shared. Invite a counterparty at any time and the project moves onto the two-party path of review, signing, and delivery.
Commitment
Something the document requires: a deliverable, a deadline, a payment, or a responsibility. Nebula tracks each one with the exact words it came from.
Baseline
The agreed state at the moment both parties signed. It is locked; later changes go through a tracked, signed variation.
Variation
A change to the work after the baseline is locked: revised scope, a new deadline, an extension of time. Each variation is recorded and signed.
Deadline
The date a commitment is due. Nebula watches deadlines and sends reminders before they slip.
Evidence
A document or file attached to a commitment to show it was met, such as a photo, certificate, or report.
Anchor
A sealed entry on the tamper-evident record that proves a moment happened, for example an agreement locked or a milestone met. See Proof you can check.
Verified
A proof that has been checked against the record and holds: it exists on both chains, the timestamps agree, and the signature traces back to who signed. Anyone can run this check.
Reliability score
An organisation's track record across reliability, responsiveness, timeliness, collaboration, and documentation, built only from proven events. New organisations start at 75. You see your own in full; others see only your tier until you release the detail.
Tier
The band an organisation's reputation falls into (Elite, Established, Trusted, or Emerging). The tier is what other organisations see in the marketplace; the exact score and the detail behind it stay private until released.
Certify
A shareable profile that surfaces an organisation's reliability score with its proof behind it.
Extension of time (EOT)
A request to move a completion date because of qualifying delays. If approved, the deadline moves and Nebula stops treating the work as late.
Defects liability period (DLP)
The period after the work is finished during which defects found must be put right. It starts once the deliverables are complete and runs for the agreed number of months.
