Struct MergeSession 

pub struct MergeSession {
    pub merge_id: MergeSessionId,
    pub src_head: Option<OpId>,
    pub dst_head: Option<OpId>,
    pub lca: Option<OpId>,
    pub auto_resolved: Vec<MergeOutcome>,
    /* private fields */
}

Stateful merge in flight. Hold one per active merge between start and commit. Sessions are not thread-safe; the HTTP wrapper is expected to wrap them in a Mutex keyed by MergeSessionId.

Fields

merge_id: MergeSessionId

src_head: Option<OpId>

dst_head: Option<OpId>

lca: Option<OpId>

auto_resolved: Vec<MergeOutcome>

Outcomes the engine resolved unilaterally — Both (both sides agreed) and one-sided (Src / Dst). The agent sees these for audit but doesn’t need to act on them.

Implementations

impl MergeSession

pub fn start( merge_id: impl Into<MergeSessionId>, op_log: &OpLog, src_head: Option<&OpId>, dst_head: Option<&OpId>, ) -> Result<Self>

Start a merge session. Runs the engine in crate::merge and partitions the outcomes into auto-resolved and conflicts-needing-attention.

pub fn remaining_conflicts(&self) -> Vec<&ConflictRecord>

Pending conflicts (those without a non-defer resolution).

pub fn resolve( &mut self, resolutions: Vec<(ConflictId, Resolution)>, ) -> Vec<ResolveVerdict>

Submit resolutions in batch. Returns one verdict per input. Accepted resolutions are recorded; rejected ones leave the previous resolution (if any) in place so partial submissions don’t clobber earlier good work.

pub fn validate_resolution( &self, conflict_id: &ConflictId, resolution: &Resolution, ) -> Result<(), ResolutionRejection>

Validate a single resolution against the session’s pending conflicts. Pure (no side effects); the caller decides whether to accept.

pub fn commit(self) -> Result<Vec<(ConflictId, Resolution)>, CommitError>

Finalize the merge. On success returns the resolved resolutions in conflict_id order. The caller is responsible for synthesizing the final Operation::Merge op against the store and persisting it; this function returns the engine’s view of “what to land,” not the persisted op id.
