"""v1 gate probes — the named tests the v1 gate (``python -m portfolio_optimiser.evals.v1_gate``)
runs to decide two of its rows. Every test here that is RED today carries
``xfail(strict=True)``, so the ordinary suite stays green while the gap is real, and the gate runs
the file with ``--runxfail`` so the gap shows as red there. ``strict`` is the other half: the day a
capability makes one of these pass, the suite goes RED on the XPASS until the marker is removed —
a closed gap cannot stay labelled open.

**Row 3 (feedback types with a way in AND an action).** Types 1, 3 and 7 are proven by EXISTING
tests elsewhere in the suite (registered by node id in ``evals/v1_gate.json``). The five types with
no complete surface (2, 4, 5, 6, 8) get a probe here that is red BECAUSE the surface is missing,
never a missing test. Each probe measures the absence (the CLI's own ``--help``); if a matching
option appears it STILL fails, naming the option — "partial is no", and a door with no observed
action is exactly partial. Such a probe goes green only when it is rewritten to drive the new door
and observe what it does.

**Row 6 (a validated proposal whose approach declared no requirement).** Two probes against the
real ``run_project`` on the shipped micro base, where the debate holds ``declare_requirement``:
no declaration anywhere, and a declaration filed for ANOTHER approach (the run's own proposal).
Neither may leave ``a1`` validated — a declaration counts only under its own approach's id.
