# Requirement: https://peps.python.org/pep-0646/
# base_commit: 26cca8067bf5306e372c0e90036d832c5021fd90 (parent of squash-
# merge commit e8e737bcf6d22927caebc30c5d57ac4634063219 —
# 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-31018:1
#
# PEP 646 is the foundational type-parameter syntax PR (the PEP-696
# `T = default` extension builds on it). It adds three new pieces of
# syntax: `class C[T, *Ts, **P]:`, `def f[T, *Ts, **P]():`, and the
# new `type Alias[T] = ...` type-alias statement. The change is broad:
# - parser: Grammar/python.gram, Parser/Python.asdl, Parser/parser.c,
# Parser/action_helpers.c
# - AST: Python/ast.c, Python-ast.c, ast_opt.c + pycore_ast*.h
# - compile/symtable: Python/compile.c, symtable.c, intrinsics.c
# - opcodes: Python/bytecodes.c + opcode_*.h
# - typing C accelerator: Objects/typevarobject.c (NEW, 1500+ lines),
# Objects/clinic/typevarobject.c.h, Modules/_typingmodule.c
# - object support: Objects/funcobject.c, typeobject.c, object.c,
# unionobject.c
# - lifecycle: Python/pylifecycle.c + assorted pycore_*.h headers
# - Python stdlib: Lib/typing.py, Lib/ast.py, Lib/keyword.py,
# Lib/opcode.py, Lib/importlib/_bootstrap_external.py
#
# 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)
