"""Project-status oracle: read-only check of repo architecture conformance.

Deterministically inspects the current repository against a standard
architecture for the auto-detected project type and prints a report with
``[OK]/[WARN]/[FAIL]`` lines, an Итог summary, and Рекомендации.

Read-only and stateless — no files are created or modified, no network
calls beyond read-only ``gh api`` for branch protection detection.

Usage:
    python3 .opencode/scripts/project-status.py           # non-blocking (exit 0)
    python3 .opencode/scripts/project-status.py --check   # strict (exit 1 on FAIL)
    python3 .opencode/scripts/project-status.py --fast    # skip slow/remote checks

Project types (auto-detected):
    fullstack — ``frontend/`` dir (SvelteKit) + ``backend/`` dir
    backend   — ``src/api/v1/`` + ``src/db/models/`` + fastapi/uvicorn in deps
    cli       — ``[project.scripts]`` in pyproject.toml + typer in deps
    bot       — ``src/bot.py`` OR aiogram in deps
    worker    — ``src/flow.py`` OR prefect in deps
    unknown   — none of the above matched (still runs a generic check set)
