 Bootstrap `.casan/casan-hook.py` tự đọc `config.json`; developer không còn phải
 source `.casan/agentic.env` trước khi mở IDE. Mỗi invocation kiểm tra live hash
 của harness global so với `version.lock` trước khi chạy adapter.
 Sau `init`, developer gõ prompt bình thường trong client — trace H1→H7 + H6 theo
 Plan-20. Repo chỉ có mấy file config nhỏ; nâng cấp harness làm ở `$CASAN_HOME`.
 ### Capability theo client
 | Lựa chọn | Trải nghiệm | Bước trust/cài đặt bắt buộc |
 |---|---|---|
 | `claude` | Claude Code CLI và extension chính thức dùng project hooks | Mở trusted project; hook chạy tự động |
 | `codex` | Codex CLI và IDE extension dùng `.codex/hooks.json` | Mở `/hooks`, review và trust đúng hook hash |
 | `vscode-copilot` | GitHub Copilot Chat qua route **explicit `@casan`** | Cài VSIX do init tạo/cài; dùng `@casan <prompt>` |
 GitHub Copilot Chat mặc định **không** có public API để CASAN intercept mọi
 prompt. Chỉ route `@casan` là `casan_owned`; participant detection/built-in
 Copilot không được quảng bá là certified.

 .SYNOPSIS
-    CASAN Plan-20 agentic-client installer for Windows PowerShell.
+  Compatibility wrapper for the Plan-21 global `casan init` workflow.
 .DESCRIPTION
-    Installs, verifies (doctor) or removes the CASAN agentic-client integration
+  New deployments should run `install.ps1` once and then `casan init` in each
-    (Claude Code and/or Codex project hooks) in a target repository — from a
+  project. This wrapper remains for existing automation, but delegates all
-    clean clone, with NO manual file copying. Every created file is recorded in a
+  merge, pin, bootstrap, doctor, and VS Code behavior to the canonical CLI.
    manifest so uninstall never touches a user's own config.
    The hooks call the CASAN agentic bridge, which never runs a model (Claude/
    Codex remains the sole model executor). See:
      docs/casan/CASAN_AGENTIC_CLIENTS_WINDOWS.md
      docs/casan/CASAN_AGENTIC_CLIENT_SECURITY.md
 .PARAMETER Action
    install | doctor | uninstall   (default: install)
 .PARAMETER Client
    claude | codex | all           (default: all)
 .PARAMETER Target
    Target repository root. Default: the repo this script lives in.
 .PARAMETER Mode
    observe | enforce              (default: observe)  — sets the bridge
    enforcement mode written into the target's .casan/agentic.env.
 .EXAMPLE
    pwsh packages/casan-devkit/windows/install-agentic.ps1 -Client claude -Mode enforce
 .EXAMPLE
    pwsh packages/casan-devkit/windows/install-agentic.ps1 -Action doctor -Client all

 # CASAN Governed Chat for VS Code
 This extension contributes an explicit `@casan` GitHub Copilot Chat route.
 CASAN opens admission before the selected Copilot model is called and finalizes
 the same trace after streaming completes.
 It intentionally does **not** claim to intercept built-in Copilot chat. Use
 `@casan <prompt>` when a CASAN-owned route is required. Claude Code and Codex
 inside VS Code continue to use their own project lifecycle hooks installed by
 `casan init`.
 The extension has no runtime dependency beyond the VS Code API and Python 3
 required by CASAN.
