"""GOAL #60 — Real-server E2E for the dedicated install flags (worktree-mounted Manager).

Boots a REAL ComfyUI server from a disposable test root
(`E2E_COMFYUI_ROOT`, built by tests/e2e/scripts/setup_e2e_env.sh) with
the Manager mounted via `git worktree add --detach` (NEVER pip-installed
— [D2]) and exercises both dedicated-flag surfaces over live HTTP.

Usage:
    bash tests/e2e/scripts/setup_e2e_env.sh            # once (E2E-SC-01)
    E2E_COMFYUI_ROOT=/path/to/root pytest tests/e2e/test_e2e_install_flags.py -v

Per-row map (goal60-scenarios.md, 24 rows — spec §3 BINDING):
  SC-01  setup_e2e_env.sh (pre-suite script; idempotent build + marker — not a pytest test)
  SC-02  mount_worktree fixture create path (SHA pin, .git-file, no-pip, printed SHA)
  SC-03  mount_worktree fixture reuse path + path-prefix scoping invariant
  SC-04  _start_server via start_comfyui.sh (readiness poll, restart tolerance,
         per-launch log comfyui.<port>.<launch-id>.log)
  SC-05  test_00_smoke_manager_version in EVERY server-up class (+abort guard)
  SC-06  _stage via stage_flags.sh (backup-if-absent; restart-only by construction)
  SC-07  class fixture finalizers (stop + port-free + config restore + backup DELETE)
         + mount_worktree finalizer (unmount + prune + absence assert)
  SC-10  TestDenyArms.test_01_sa_deny           SC-11  TestDenyArms.test_02_sb_deny
  SC-12  TestAllowArms.test_01_git_url_allow
  SC-13  TestAllowArms.test_02_pip_allow_reserved      (anti-false-PASS — VERBATIM)
  SC-14  TestAllowArms.test_03_restart_consumes_reservation (R-A through the holder)
  SC-20  _pre_guards in both class fixtures (before any request)
  SC-21  TestAllowArms.test_04_clone_residual_cleanup (+ installed-index cross-check)
  SC-22  TestAllowArms.test_05_pip_residual_uninstall
  SC-23  _reservation_guard — UNCONDITIONAL fixture-teardown guard (failure path)
  SC-24  TestZeroResidual.test_99_zero_residual_sweep (unmount half lives in the
         mount_worktree finalizer — it cannot be asserted from inside the session)
  SC-30  module-level pytestmark (env unset -> all SKIP; unit suite unaffected)
  SC-31  module-level pytestmark (marker absent -> all SKIP)
  SC-32  needs_network marker on fixture-dependent (allow-arm / public) rows
  SC-33  collection safety by construction: stdlib + pytest + requests
         (via pytest.importorskip) ONLY — no glob/ imports, no server imports,
         HTTP only at test time
  SC-40  TestPublicListener (opt-in E2E_PUBLIC_LISTEN=1; L-P @ 0.0.0.0)
  SC-41  batch S-C/S-C' E2E — DEFERRED (Q-5; spec FREEZE item 3; recorded here)
  SC-42  TestAllowArms.test_06_requirements_watchdog (L-A launch log)

Fixture-lifecycle ownership (spec §3 BINDING block):
  - every class server fixture DECLARES mount_worktree (mount-before-launch);
  - process handle lives in a MUTABLE ServerHolder owned by the fixture;
    teardown stops the CURRENT holder content (whatever launch identity is live);
  - SC-14 restarts THROUGH the holder (stop L-A -> launch R-A -> replace handle);
  - stop-before-next-class is structural (pytest class-fixture scoping);
  - `requests` is imported via pytest.importorskip (absence degrades to SKIP).

T6 note: no tests/e2e/conftest.py — all fixtures are single-module, so the
optional T6 file is not demanded (spec §2 T6 condition not met).
