Enum EngineFailureCode 

pub enum EngineFailureCode {
    ConfigInvalid,
    CoreIncomplete,
    ContentUnavailable,
    PolicyIncomplete,
    PatchInvalid,
    PatchConflict,
    FixCycle,
    FixPassLimit,
    TransactionFailed,
    IndexLockUnprovenOwner,
}

What: The stable causes of an engine failure this foundation and its successors report. #[derive(...)] generates copying, debug printing and ==. Why: A closed set keeps the wire spelling in one place. Codes that described plugins and trust are not carried over. A shipped policy that could not finish is reported by cause: ContentUnavailable when something it had to read could not be read, PolicyIncomplete when its own machinery failed.

In TS you’d write (pseudocode):

type EngineFailureCode = 'config-invalid' | 'core-incomplete' | ... | 'index-lock-unproven-owner';

Variants

ConfigInvalid

Configuration could not be read or validated, including legacy files needing migration.

CoreIncomplete

A fixed transform failed unexpectedly.

ContentUnavailable

Something a policy or lifecycle had to read could not be read: a candidate’s bytes, a repository fact asked of Git, or transaction state. The policy itself is intact; its input is missing.

PolicyIncomplete

A shipped policy’s own machinery failed, so the policy could not finish although its input was readable: its rules file could not be loaded, its linter could not start, or it hit an internal error. An unreadable candidate or repository fact is ContentUnavailable instead.

PatchInvalid

A proposed patch was not valid.

PatchConflict

A proposed patch no longer applied.

FixCycle

Fixing revisited an earlier state.

FixPassLimit

Fixing did not settle within the pass limit.

TransactionFailed

A commit transaction could not complete.

IndexLockUnprovenOwner

A foreign index.lock with an unproven owner outlasted the wait budget.
