"""IDENTITY CLEANUP-PROMPT (C1) — the additive render-steer channels on the identity
specs (operator-requested 2026-07-15).

Two knobs, both additive, both default ``""`` -> byte-identical to today
(defaults-are-promises):
  * ``IdentityMeshSpec.cleanup_prompt``  — a positive-worded avoid instruction woven into
    the T-pose front render prompt (C2 wires it into ``_TPOSE_PROMPT``).
  * ``IdentityMeshSpec.negative_prompt`` — a true negative forwarded to the studio render.
  * ``IdentityReconstructionSpec.negative_prompt`` — the reconstruction/turntable render's
    true negative (base_prompt already covers the positive channel there, so ONLY the
    negative is added to the reconstruction spec).

This is a PURE-SCHEMA test (no store / no bus / no GPU): it exercises make_identity_mesh +
identity_mesh_from_dict and the reconstruction spec's negative round-trip through the LIVE
module path. NOTE a PRE-EXISTING landmine documented for the keeper: the module exports a
SECOND ``def make_identity_reconstruction(**kwargs)`` (the bare passthrough, further down
the file) that SHADOWS the validating factory — so the reconstruction spec's field
validation is unreachable via the public name (this predates the cleanup slice; base_prompt
has the same dead validation). We therefore assert the reconstruction ROUND-TRIP through the
live from_dict path, and the ValueError-on-non-str behavior against the MESH factory (which
is singly defined -> its validation is LIVE).

Run (both as pytest and as a script; run ALONE — the identity test family cross-pollutes):
