}Expand description
What:
landing-<n>.json:
one landing attempt inside the critical section.
Why:
Recovery decides from it whether the attempt landed and completes or discards it.
In TS you’d write (pseudocode):
type LandingRecord = { schemaVersion: 2; state: 'landing'; attempt; operation; expectedOld; newOid?; ... };Fields§
§attempt: i64Landing attempt number, from 1.
operation: LandingOperationLanding kind.
expected_old: BaseExpected old target value for compare-and-swap.
new_oid: Option<String>New target value; absent for a normalization.
landed_tree_oid: StringTree the landing installs into the real index.
pre_landing_index: FileIdentityExact pre-landing real index snapshot identity.
post_index: FileIdentityExact post-index artifact identity.
lock: LockIdentityReal index.lock identity.
pack_name: Option<String>Migrated pack name; absent for a normalization.
added_paths: Vec<AddedPath>Policy-added path records.
selected_worktree_paths: Vec<AddedPath>Selected worktree completion records.
pre_landing_digest: Option<ContentDigest>Length and hash of the pre-landing snapshot as written; absent in a record written before digests existed.
post_digest: Option<ContentDigest>Length and hash of the post-index as written; absent in a record written before digests existed.
