}

Failure modes of view folding and commit storage.

Variants

StaleHead

CAS failure: prev did not match the current head/target.

Fields

target: String

The workspace or ref name that was targeted.

expected: Option<ContentHash>

What the op expected the current value to be.

actual: Option<ContentHash>

What the view actually held.

Decode(String)

Payload or stored commit bytes failed to decode.

Log(LogError)

Underlying op-log failure.

Store(StoreError)

Underlying chunk-store failure.

Review(String)

Review-op precondition failure (duplicate id, unknown review, or a reviewer not on the review’s list).

Provenance(String)

Provenance-record precondition failure (empty subject or kind).

Check(String)

Check-report precondition failure: an empty name or reporter, or a name carrying the key separator.

Change(String)

Change lifecycle precondition failure (duplicate identity, invalid binding, unknown/archived change, or no-op checkpoint).

Identity(String)

Key-binding precondition failure: an empty or /-bearing operator, a channel that reads as a different operator, a key already bound elsewhere, or a revoked/unbound key.

Snapshot(String)

Ref-snapshot precondition failure: the claimed ref map does not match the view, the claimed position is not the fold position, or the chain pointer does not name the latest admitted snapshot.

Resolution(String)

Resolution-link precondition failure: Commit::resolves names a commit the store does not hold, or one with nothing to resolve.

Vouch(String)

Vouch precondition failure (D65): an end that is not an operator with an unrevoked binding, a self-vouch, an edge that already stands, or a withdrawal of one that does not.

Witness(String)

Witness precondition failure (D67): a witness with no live key binding, a cosignature over anything but the latest ref-state attestation, or one that witness has already made.

Trait Implementations
