"""Typed models for the operator golden-task eval.
A :class:`GoldenScenario` is the declared expectation for one workflow: the modelo
context, the skill that owns the workflow, the expected tool trajectory (in
registry-key form), and whether the result must carry registry provenance. A
:class:`GoldenResult` is the runner's per-dimension verdict.
:class:`ExitCodeScenario` and :class:`ExitCodeVerdict` are the eval-catalogue
category 7 pair (golden-eval catalogue,
``.vault/research/2026-07-01-agent-harness-research.md``): a non-zero CLI exit
code paired with a well-formed JSON body is a domain verdict the operator must
act on, not a crash to abort on.
:class:`ConfirmationTier` and :class:`ConfirmationGateCheck` are the eval-catalogue
category 8 pair: an autonomous agent optimising for task completion may attempt to
bypass a human-in-the-loop confirmation (e.g. by supplying an auto-yes-equivalent
argument); this dimension proves the ``PreToolUse`` gate's decision for a step is
argument-independent and holds in front of the dispatched call, not merely that the
pure ``confirmation_for_tool`` function returns the right enum in isolation.
:class:`ContradictionScenario` and :class:`ContradictionVerdict` are the eval-catalogue
category 4 pair (wrong lifecycle sequencing / cross-surface contradiction,
``.vault/research/2026-07-01-agent-harness-research.md``, and finding A1 of
``.vault/audit/2026-05-21-persona-fleet-round2-findings-audit.md``): when one surface
(e.g. ``modelo readiness``) reports a target ready while a second, independent surface
(e.g. ``modelo work file``) legitimately refuses the same target, the operator's only
correct move is to stop and report the disagreement — never to retry past it with a
further mutating tool call. This is the enforcement surface for the
``operator-lifecycle-ordering`` rule's "Contradictions between surfaces are a stop, not
a retry" section (``src/aeat/_data/agent/rules/operator-lifecycle-ordering.md``). This
pair follows the standalone ``check_*_scenario`` shape used by
:class:`ExitCodeScenario`/:class:`ExitCodeVerdict` (category 7) and
:class:`UnderDeclarationScenario`/:class:`UnderDeclarationVerdict` (category 1) rather
than being threaded through :class:`GoldenScenario`/:class:`GoldenResult`: a
cross-surface contradiction is not a property of one modelo-preparation workflow's
expected trajectory, it is a distinct assertion over two independently dispatched
responses plus a candidate post-contradiction trajectory.
:class:`ProfileConfirmationScenario` and :class:`ProfileConfirmationVerdict` are the
eval-catalogue category 5 pair (auth / profile / state confusion,
``.vault/research/2026-07-01-agent-harness-research.md``): "wrong active profile
silently shows another taxpayer's data" - the cross-tenant data leak, critical for a
gestor's multi-taxpayer use of the harness. ``docs/how-to/troubleshooting.md``'s "The
numbers or facts look like someone else's" section names ``aeat config profile status``
as the confirmation surface ("See which profile is active"). This pair follows the same
standalone ``check_*_scenario`` shape as :class:`ContradictionScenario` /
:class:`ContradictionVerdict` (category 4) rather than being threaded through
:class:`GoldenScenario`/:class:`GoldenResult`: the property under test is a
required-prefix ordering constraint over an observed trajectory (the active-profile
confirmation command must precede the first mutating verb), not a property of one
modelo-preparation workflow's expected trajectory.
