Build Momentum 20How it is measured

Latest ship
Code changes, week of 2026-09-14 – 2026-09-20 · 6 commits · · Code activity

Why it matters: One of a run of ships in the 30 days to it: building continued, not a one-off.

This change
Code changes, read from the team’s GitHub · not a deployment
What it names
1 of 2 commits HEY read changed code. A week of code names no capability.
Stage
Code changes are not a deployment: HEY has not observed a release or a deployment of this code.
Reported by
Read from the team’s GitHub. Reported in the team’s own source. No independent record HEY holds corroborates it.
Release and deployment
Not a release or a deployment: code is not a deployment.
Activity
No contract is tied to this change, so no product activity is attributed to it. Product usage is read on its own.
When
The source dates it to the week of 2026-09-14; HEY first knew on 2026-09-18. HEY indexed it later, as history.
Not known
  • No source HEY holds names what this change does.
  • HEY has not observed a deployment of this change.

Evidence: ship record

A ship says what was shipped and where HEY read it. It is not a judgement of quality, of the team, or of what the token will do.

Follow puts vellum on your private watchlist; its changes then lead “Since you were last here” when you come back. Following needs an account; browsing never does.

What HEY checked — why it says this
Active.
“Active” by the activity rule's longer window: 2 meaningful events in the last 45 days (the rule needs at least 2); the newest, 2026-09-14, is more than 30 days old.

Code activitySource linked

What changed, in the repository’s own words:

1 active day in linxule/vellum.

This week HEY looked inside 2 of 6 commits to see what changed: 1 changed code, 1 documentation or maintenance only. One code change is enough for the week to count, so HEY stopped there. 3 automated commits (bot accounts or a repeating scripted message) not counted.

Record ship:35543b03… · HEY counts it as building; it does not judge the release’s quality or what it means for the token.
