Enum FailedRefExportReason 

pub enum FailedRefExportReason {
    ModifiedConcurrentlyInGit {
        found: ObjectId,
        intended: ObjectId,

Why a single ref could not be published to the Git projection.

Every arm is a REPORT, never an attempted repair: heddle names what it found on the Git side and leaves the ref exactly as it is, for the operator to reconcile (import first, or force). Auto-resolving a ref another writer just moved is how that writer’s commits get lost.

Variant names are heddle-native but map 1:1 onto jj’s FailedRefExportReason (lib/src/git.rs), so a future port translates without re-deriving the taxonomy: ModifiedConcurrentlyInGit <-> jj DeletedInJjModifiedInGit, DeletedInGit <-> jj ModifiedInJjDeletedInGit, and FailedToSet / FailedToDelete <-> the same-named jj arms.

Variants

ModifiedConcurrentlyInGit

The Git ref does not hold the value heddle based its update on: it moved underneath the export (a git push, git branch -f, or another tool writing the mirror). Covers both the tip that had ALREADY diverged when export read it and the one that changed inside the read-write window.

Fields

found: ObjectId

What Git holds – the value that lost heddle the compare-and-swap.

intended: ObjectId

The tip heddle was publishing when it lost the race.

DeletedInGit

heddle read the ref, then found it gone by the time it wrote: deleted on the Git side mid-export.

Fields

intended: ObjectId

The tip heddle was publishing when the ref disappeared.

FailedToSet(String)

The ref write failed for a reason that is NOT a demonstrable race – a locked ref, an IO error, an invalid name. Kept distinct so a lost race is never inferred from a failure we cannot attribute to another writer.

FailedToDelete(String)

The ref delete failed, likewise for a non-race reason.
