Module queue 

The node’s own merge queue (D68).

The bridge queues pull requests from somebody else’s forge. A node has no pull requests; it has proposals, which are pushes to refs/for/<branch>/<user>/<topic> admitted by the propose grant (D53, D60). This is the reading that turns those refs into a round, and the landing that writes the round’s result back where the log decides.

Two things differ from the bridge’s composition, and both come from the same fact: here the log is the source of truth.

• A landing is real. It moves refs/heads/<branch>, so it is an OpKind::SetRef carrying the value the round started from as its compare-and-swap prev. A push that beat the round makes the landing fail rather than clobber.
• The node moves no git ref itself. crate::Platform::reconcile_git_refs already treats a commit the log names and git does not as git being behind, and writes it. The log leads and git follows, which is the direction D21 fixed.

Structs

ProposalRound

The proposals aimed at one branch of one repository, plus the base they are aimed at.

RefLanding

Lands by moving the branch the proposals were aimed at (D68).

Constants

QUEUE_CHANNEL

The channel the node’s queue authors under.

Type Aliases

ScopeSource

Where a landing reads the scope it signs: this node’s id and a head its window still holds.
