# #478 — Transformers pin for the dedicated floor-compat CI job.
#
# Declared train floor in pyproject.toml remains:
#   transformers>=4.36.0,<5.0.0
#
# transformers==4.36.0 is not resolvable with the declared trl range
# (trl>=0.14.0,<0.29): even trl 0.14.0 requires transformers>=4.46.0, and
# newer trl releases require >=4.56.1 / >=4.56.2. Raising Soup's declared
# transformers floor in pyproject.toml needs an explicit maintainer
# dependency-policy decision. Do NOT treat 4.55.4 (the last pre-dtype=
# release) as the declared floor.
#
# This file pins:
#   transformers==4.46.1 — lowest non-yanked resolvable Transformers version
#     tested with the lowest declared TRL version
#   trl==0.14.0 — lowest version in Soup's declared trl range
#
# These pins are for the floor CI cell only so pip cannot silently upgrade
# that job. Do not describe pip's preferred/latest compatible TRL as the
# floor. Runtime dtype= regressions are caught by the static guard in
# tests/test_transformers_floor_compat.py (dtype= is >=4.56-only).
