Enum VerifyFailureKind 

pub enum VerifyFailureKind {
    Parse,
    SelfHash,
    ChainBreak,
    Sequence,
}

Why the per-line audit-event hash chain (AuditEvent JSONL files under audit/) failed to verify.

Disambiguation (issue #970)

A sibling enum crate::governance::audit::VerifyFailureKind exists for the governance forensic-bundle chain (Ed25519-signed ForensicDecision rows in signed_events). Despite the shared name, the two enums verify different chain shapes and have different variant sets:

• audit::VerifyFailureKind (this enum): Parse, SelfHash, ChainBreak, Sequence. The audit chain hashes each line’s canonical bytes (SelfHash) and verifies a monotonically increasing sequence (Sequence). It does NOT sign rows individually.
• governance::audit::VerifyFailureKind: Parse, ChainBreak, Signature. The forensic chain signs each row with an Ed25519 key (Signature) and verifies the cross-row hash pointer (ChainBreak). It has no per-line SelfHash (signature verification subsumes it) and no Sequence variant (sequence is a SQLite column, not a line counter).

They are call-site-disambiguated by their module path. See docs/internal/enum-proliferation-audit-970.md.

Variants

Parse

Line could not be parsed as an AuditEvent.

SelfHash

Recomputed self_hash did not match the stored value.

ChainBreak

Stored prev_hash did not match the prior line’s self_hash.

Sequence

sequence did not increase monotonically.

Trait Implementations

impl Clone for VerifyFailureKind

fn clone(&self) -> VerifyFailureKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VerifyFailureKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for VerifyFailureKind

impl PartialEq for VerifyFailureKind

fn eq(&self, other: &VerifyFailureKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
