Struct AttestationLog 

pub struct AttestationLog { /* private fields */ }

Persistent log of Attestation records.

Mirrors crate::OpLog / crate::IntentLog in shape: one canonical-JSON file per attestation, atomic writes via tempfile + rename, idempotent on re-puts. Adds a by-stage/ index so “list every attestation for stage X” is O(attestations on X) rather than O(all attestations).

Implementations

impl AttestationLog

pub fn open(root: &Path) -> Result<Self>

pub fn put(&self, attestation: &Attestation) -> Result<()>

Persist an attestation. Idempotent on existing ids — content addressing guarantees the same logical attestation produces the same id, so re-putting is a no-op for the primary file. The by-stage index is also re-written idempotently.

pub fn get(&self, id: &AttestationId) -> Result<Option<Attestation>>

pub fn list_all(&self) -> Result<Vec<Attestation>>

Enumerate every attestation in the log. Walks <root>/attestations/*.json directly — no per-stage index — so cost is O(total attestations). Used by lex attest filter for CI / dashboard queries that span stages. Order is not stable; callers that need stable ordering should sort by timestamp or attestation_id.

pub fn list_for_stage(&self, stage_id: &StageId) -> Result<Vec<Attestation>>

Enumerate attestations for a given stage. Order is not stable across calls (it follows directory iteration order). Callers that need a stable ordering should sort by timestamp or attestation_id.
