Enum Closed 

pub enum Closed {
    Cleared,
    LeftForRecovery(Box<Lingering>),
}

What closing a session did.

Variants

Cleared

Written back where asked, and the session directory removed.

LeftForRecovery(Box<Lingering>)

The target application still has things of its own in the content directory, so the session was handed to recovery instead of being removed. Concept 6.2: the close is honoured, but deleting the directory underneath a running editor sends its next save nowhere this tool will ever look.

The watch comes with it. Concept 8: what a resident process is good for on this path is noticing the application’s last save when it happens, rather than leaving the question until somebody next opens a container.

Boxed because of what the watch weighs on macOS. The first time the gate ran on a Mac, 2026-09-07, clippy refused this enum for a variant carrying nothing beside one carrying 256 bytes, and size_of put the numbers on it there: Lingering 256, of which Watch is 144, of which the platform’s watcher is 128. A close is not a hot path, so the indirection costs nothing anybody would notice.
