Module graduation 

Honest Python-to-Rust/component graduation workflow.

The workflow scaffolds adapters and verifies recorded behavior. It never claims to translate arbitrary Python business logic. Candidate publication, attestation, activation, and rollback are serialized and digest-bound.

Structs

ComparisonRequest

Host-owned inputs for one bounded Python/component dual-run.

ConformanceAttestation

Successful, digest-bound conformance evidence required by activation.

GraduationArtifact

Immutable component identity retained in the graduation workspace.

GraduationFixture

One recorded Python input/output pair used for component conformance.

GraduationState

Durable state for one graduation workspace.

Functions

activate

Publish the attested candidate into the live provider directory.

build_component

Build (or import), verify, and publish an immutable candidate artifact.

commit_transaction

Commit a live activation only after the caller has refreshed and verified the active provider generation.

compare

Replay fixtures and persist digest-bound conformance evidence.

graduate

Scaffold a reusable Rust core plus thin PyO3 and WIT adapters.

is_ambiguous_commit

Whether commit crossed the atomic marker transition but failed its directory durability sync. Such errors must never trigger rollback.

recover

Restore the exact pre-operation provider files and graduation state.

recover_all

Recover interrupted transactions beneath an operator-owned graduation root before provider discovery observes partially promoted files.

rollback

Reactivate the retained component, or restore the original Python source.

status

Read-only operator status with integrity checks for referenced artifacts.

verify_component

Validate a component artifact against the versioned WIT runtime.
