The contract

It’s already written. You just sign.

The winter arc comes preloaded: the seven lines, the dates, the stakes. Nothing to set up.

The community board with the Winter Arc poster

It’s pinned on the community board.

02
Choose how: with everyone, with an accountability partner, or on your own

Choose how: with everyone, with a partner, or on your own.

03

Read every line. Same paper for everyone.

04
Sign your contract: draw your initials

Draw your initials and hold to sign.

The stakes

TO WIN

The Winter Arc seal and 25,000 rank points.

TO LOSE

No seal, no points, and it ends BROKEN on your record.

Two missed days in a row, or two short training weeks in a row, and it ends.

Cura signs as witness.

Every Winter Arc carries Cura’s signature beside yours. It’s on the record from the day you sign.

Do it together

Don’t do it alone.

A rule someone sees is a contract. Pick the one who’ll actually check.

You see their day. They see yours.

01 · choose

Pick a partner.

When you sign, choose “an accountability partner signs it with me”. Keep the terms and the Winter Arc seal is still yours.

Change a line or the dates and it becomes your own contract, without the Winter Arc seal.

An accountability partner signs it with me, selected: keep the terms, keep the seal
02 · sign

They sign beside you.

Your partner signs the same paper, in their own hand. Cura signs as witness.

03 · nudge

Not in yet? Nudge them.

When their day is still open, one tap tells them you noticed.

A partner's page: not in yet today, with a nudge button

Or sign it with everyone on the board, or on your own with Cura as witness. It holds better with someone watching.
