#!/usr/bin/env python3
"""
Scoped variant of ``dev-sync`` for the LTX 2.3 audio-lipsync automation.

Copies only what that automation's iteration loop touches:

    - forks/whatdreamscost_koolook/    the Koolook fork of LTXDirector +
                                       its modified prompt_relay + the
                                       verbatim-vendored patches.py
    - __init__.py                      root loader (registers the fork's
                                       node mappings; needs to be re-synced
                                       when the fork's NODE_CLASS_MAPPINGS
                                       set changes)
    - web/whatdreamscost_koolook/      Director timeline-editor extension
    - web/koolook_draft_guard.js       global Comfy draft-quota guard
                                       (formerly embedded in the Director
                                       extension; shipped so a scoped sync
                                       never strands a guard-less install)

It also ships ``koolook_install_guard.py`` + ``koolook_versioning.py`` — the
loader gates ``__init__.py`` imports at load — so a scoped sync never leaves
the loader pointing at a module the target lacks (#198 / #183).

Everything else in the live install - ``forks/radiance_koolook/``, the
root ``k_*.py`` nodes, unrelated ``web/`` assets, ``video_formats/`` -
is left untouched.

USER-INITIATED ONLY. Same rule as plain ``dev-sync`` (see project
``CLAUDE.md`` -> ``dev-sync`` section). Never run automatically:

  * after a commit
  * after a PR merge or ``/ship-pr``
  * at session end / wrap-up
  * on hook completion or "task complete" cleanup
  * from any agent skill that doesn't explicitly require it

Run only on the explicit user trigger phrase ``dev-sync-audio`` (or
``copy audio fork``, ``sync audio``, etc.). The maintainer typically has
multiple parallel sessions across worktrees; an unsolicited sync from one
silently destroys what another is reviewing.

The target path comes from ``KOLOOK_COMFYUI_DEV_PATH`` in ``.env`` -
identical to plain ``dev-sync``. No new env var.

Usage:
    python scripts/sync_to_dev_audio.py
    python scripts/sync_to_dev_audio.py --dry-run
    python scripts/sync_to_dev_audio.py --scope "vstr=10 trial"

Exit codes mirror ``sync_to_dev.py`` exactly:
    0  success
    2  KOLOOK_COMFYUI_DEV_PATH unset or target missing without --init
    3  --init refused

After copying Python files, restart ComfyUI manually so custom nodes are
re-imported. This scoped sync only copies files.
