# Requirement: https://peps.python.org/pep-0709/
# base_commit: 0aeda297931820436a50b78f4f7f0597274b5df4 (parent of squash-
# merge commit c3b595e73efac59360d6dc869802abc752092460 —
# see spec.json base_commit_note)
#
# Agent-facing contract (the agent does NOT run anything inside this image;
# the evaluator runs the container after the agent submits a solution.patch):
#
# docker run --rm \
# --network=none \
# -v $(pwd)/solution.patch:/in/solution.patch:ro \
# -v $(pwd)/out:/out \
# lolbench/cpython-pr-101441:1
#
# PEP 709 inlines list/set/dict comprehensions into their enclosing scope,
# removing the synthetic function frame the old implementation used. The
# change is C-heavy (compile.c, symtable.c, bytecodes.c, flowgraph.c,
# assemble.c, generated_cases.c.h, opcode_targets.h, opcode_metadata.h,
# frameobject.c, plus pycore headers) with two small Python edits
# (Lib/opcode.py + Lib/importlib/_bootstrap_external.py for the bytecode
# magic-number bump).
#
# No special capabilities are needed. The container stays --network=none
# with the default seccomp profile.
#
# Because the agent's code never executes here, the container runs every
# step as root — no agent UID, no chown of /usr/local, no runuser dance.
#
# Layered build per docs/executable_environment_plan.md §4:
# layer 1: ubuntu:22.04
# layer 2: lolbench/cpython-base:1 (toolchain + stdlib build deps)
# layer 3: THIS image (cpython @ base_commit + built python + private bundle)
