Transition Table Code Representation

Canonical source: Admissible-Existence/TT. This Site page is a public mirror surface only. It does not redefine Transition Table semantics or grant execution authority.

Purpose

This page explains how Transition Table elements are represented as canonical registry entries, code references, fixtures, receipt schemas, and generated mirror status.

Representation Chain

Transition Table element
        |
        v
canonical registry entry
        |
        v
specific code reference
        |
        v
test fixture
        |
        v
receipt-producing evaluation

Required Element Fields

Field	Purpose
`transition_id`	Stable Transition Table element identifier.
`transition_name`	Canonical human-readable transition name.
`transition_family`	Canonical family grouping.
`code_ref`	Declared handler path and symbol.
`fixture_ref`	Declared fixture path.
`receipt_schema_ref`	Declared receipt schema path.
`implementation_status`	Whether the element is implemented, default-handler, scaffolded, missing, or deprecated.
`propagation_status`	Whether downstream mirrors are pending, mirrored, superseded, or blocked.

Current Site Mirror Status

The generated Site mirror status is available at:

Fail-Closed Rule

If Site displays, indexes, or routes a transition element whose canonical TT registry entry lacks a valid code_ref, fixture_ref, or receipt_schema_ref, the mirrored status must mark the element as not operational and downstream evaluators should return FAIL_CLOSED.

Authority Boundary

A rendered Site page, registry entry, code reference, fixture, or passing mirror check does not grant execution authority. SPE must still reconstruct current standing before any commit boundary is allowed.
