feat(harness): implement Plan-20 transparent agentic client bridge
Wave 0 + Wave 1 core of the transparent agentic-client integration: a
developer types prompts normally in Claude Code / Codex while every
certified turn still carries a full H1->H7 trace and an H6 record.
- agentic_bridge.py: stdlib-only lifecycle state machine (begin/pre-tool/
post-tool/telemetry/finalize/abort + report/doctor). Single-model
invariant (never calls a model), fail-closed at the side-effect point,
admission TTL + canonical-project/session binding, atomic state under
.specify/state/agentic-sessions/, secret redaction, null-not-zero H6.
- agentic-lifecycle.schema.json: client-agnostic JSON contract.
- adapters/claude-code + adapters/codex: thin hook renderers + config
templates that call the core bridge.
- phase-agentic-bridge-tests.sh: C1-C12 acceptance + threat suite (30/30).
- devkit templates/{claude,codex} + windows/install-agentic.ps1
(install/doctor/uninstall with manifest, path-safe).
- docs/casan Windows + security/bypass guides; plan status -> IMPLEMENTED.
- harden generate-agentops-dashboard.py aggregation against null H6 costs.

# CASAN Agentic Clients trên Windows (Plan-20)
|
||||
|
||||
Tài liệu hướng dẫn cài đặt tích hợp **transparent agentic client** của CASAN cho
|
||||
Windows: developer gõ prompt bình thường trong Claude Code hoặc Codex, nhưng mọi
|
||||
turn được chứng nhận vẫn có trace H1→H7 và record H6 đầy đủ.
|
||||
|
||||
Liên quan:
|
||||
[Plan-20](../plans/CASAN_PLAN_20_AGENTIC_CLIENT_INTEGRATION.md) ·
|
||||
[Spike-20](../spikes/CASAN_SPIKE_20_AGENTIC_CLIENT_HOOKS.md) ·
|
||||
[Bảo mật/bypass](CASAN_AGENTIC_CLIENT_SECURITY.md).
|
||||
|
||||
## 1. Nguyên tắc quan trọng
|
||||
|
||||
- **Không chạy model hai lần.** Bridge chỉ làm admission/policy/evidence/finalize.
|
||||
Claude/Codex vẫn là bộ chạy model duy nhất (single-model invariant).
|
||||
- **Fail-closed tại điểm side-effect.** Một tool có tác động bị từ chối khi không
|
||||
có admission hợp lệ, còn hạn và gắn đúng project/session.
|
||||
- **Certification strength hiển thị công khai.** Mỗi trace mang
|
||||
`project_hook` / `managed_hook` / `casan_owned` / `observed_only`; observe mode
|
||||
luôn là `observed_only` và không bao giờ được cấp certified.
|
||||
|
||||
## 2. Yêu cầu nền
|
||||
|
||||
- Windows PowerShell 5.1 trở lên (hoặc PowerShell 7+/`pwsh`).
|
||||
- Python 3 trên PATH (`python3`, `python`, hoặc `py`). Bridge chỉ dùng stdlib —
|
||||
không cài thư viện mới.
|
||||
- Repo dự án đã adopt CASAN core (`packages/casan-harness` tồn tại). Nếu chưa,
|
||||
xem [CASAN_ADOPTION_WINDOWS.md](CASAN_ADOPTION_WINDOWS.md).
|
||||
|
||||
Kiểm tra nhanh:
|
||||
|
||||
```powershell
|
||||
python3 --version
|
||||
Test-Path .\packages\casan-harness\scripts\python\agentic_bridge.py
|
||||
```
|
||||
|
||||
## 3. Cài đặt từ clone sạch (không copy file thủ công)
|
||||
|
||||
Installer PowerShell tự đặt config vào đúng chỗ và ghi manifest để gỡ sạch.
|
||||
|
||||
```powershell
|
||||
# Cài cho cả Claude Code lẫn Codex, bắt đầu ở chế độ observe (an toàn)
|
||||
pwsh .\packages\casan-devkit\windows\install-agentic.ps1 -Client all -Mode observe
|
||||
|
||||
# Chỉ Claude Code
|
||||
pwsh .\packages\casan-devkit\windows\install-agentic.ps1 -Client claude
|
||||
|
||||
# Bật enforce khi đã sẵn sàng cấp certified
|
||||
pwsh .\packages\casan-devkit\windows\install-agentic.ps1 -Client all -Mode enforce
|
||||
```
|
||||
|
||||
Installer sẽ:
|
||||
|
||||
1. Copy `settings.json` → `.claude\settings.json` và/hoặc `hooks.json`/`config.toml`
|
||||
→ `.codex\`. File cũ của bạn được backup thành `*.casan-bak`.
|
||||
2. Ghi feature flags vào `.casan\agentic.env`.
|
||||
3. Ghi `.casan\agentic-install-manifest.json` để uninstall không đụng config
|
||||
riêng của bạn.
|
||||
4. Chạy doctor tự động.
|
||||
|
||||
> Đường dẫn có dấu cách được xử lý đúng (ví dụ `C:\Users\Nguyen Van A\project`).
|
||||
|
||||
## 4. Doctor và smoke test
|
||||
|
||||
```powershell
|
||||
pwsh .\packages\casan-devkit\windows\install-agentic.ps1 -Action doctor -Client all
|
||||
```
|
||||
|
||||
Doctor kiểm tra: interpreter Python, sự hiện diện của hook config, các gate
|
||||
H4/H2, quyền ghi state, và chạy một turn begin→admission thật trên state tạm.
|
||||
|
||||
Có thể gọi bridge trực tiếp:
|
||||
|
||||
```powershell
|
||||
python3 .\packages\casan-harness\scripts\python\agentic_bridge.py doctor
|
||||
```
|
||||
|
||||
## 5. Dùng thử
|
||||
|
||||
1. Mở repo trong Claude Code (hoặc Codex).
|
||||
2. Với Codex: chấp nhận **trust prompt** để project hook được load (bước bắt
|
||||
buộc, doctor sẽ nhắc).
|
||||
3. Gõ prompt bình thường. Một prompt vi phạm policy (ví dụ chứa role-hijack) bị
|
||||
chặn trước model theo khả năng của client.
|
||||
4. Khi turn kết thúc, xem H6:
|
||||
|
||||
```powershell
|
||||
# Lọc report H6 theo client / integration_mode / trace_id / project
|
||||
python3 .\packages\casan-harness\scripts\python\agentic_bridge.py report --client claude-code
|
||||
```
|
||||
|
||||
## 6. Feature flags
|
||||
|
||||
Đặt trong `.casan\agentic.env` hoặc biến môi trường session:
|
||||
|
||||
| Biến | Mặc định | Ý nghĩa |
|
||||
|---|---|---|
|
||||
| `CASAN_AGENTIC_BRIDGE_ENABLED` | `1` | Bật/tắt tổng. |
|
||||
| `CASAN_AGENTIC_ENFORCEMENT_MODE` | `observe` | `observe` (chỉ telemetry, không certified) → `enforce`. |
|
||||
| `CASAN_AGENTIC_INTEGRATION_MODE` | `project_hook` | `project_hook` / `managed_hook` / `casan_owned`. |
|
||||
| `CASAN_AGENTIC_CLIENT_ALLOWLIST` | (trống) | Danh sách client; ngoài danh sách → `observed_only`. |
|
||||
| `CASAN_AGENTIC_TTL_SECONDS` | `1800` | TTL admission. |
|
||||
| `CASAN_AGENTIC_INTERNAL_TIMEOUT` | `8` | Internal timeout của bridge (ngắn hơn outer hook timeout). |
|
||||
| `CASAN_AGENTIC_H2_REGISTRY` | `0` | Bật thêm H2 tool-registry gate (cho managed deployment có agent identity). |
|
||||
|
||||
Nạp flags trong PowerShell:
|
||||
|
||||
```powershell
|
||||
Get-Content .\.casan\agentic.env | Where-Object { $_ -and -not $_.StartsWith('#') } | ForEach-Object {
|
||||
$k,$v = $_ -split '=',2; Set-Item -Path Env:$k -Value $v
|
||||
}
|
||||
```
|
||||
|
||||
## 7. Gỡ cài đặt (không xóa config của user)
|
||||
|
||||
```powershell
|
||||
pwsh .\packages\casan-devkit\windows\install-agentic.ps1 -Action uninstall -Client all
|
||||
```
|
||||
|
||||
Uninstall chỉ xóa file do CASAN tạo (theo manifest) và khôi phục bản backup
|
||||
`*.casan-bak` nếu có.
|
||||
|
||||
## 8. Xử lý sự cố
|
||||
|
||||
| Triệu chứng | Nguyên nhân | Cách xử lý |
|
||||
|---|---|---|
|
||||
| Prompt không bị chặn dù có hook | Outer hook timeout của client (fail-open đã ghi nhận) | Side-effect vẫn bị `PreToolUse` từ chối khi thiếu admission; giảm tải hook, xem log H6 failure |
|
||||
| Codex không chạy hook | Chưa qua trust review | Mở repo trong Codex, chấp nhận trust; chạy lại doctor |
|
||||
| Turn hiện `observed_only` | Đang ở observe mode hoặc client ngoài allowlist | Đặt `-Mode enforce`, thêm client vào allowlist |
|
||||
| Token/cost là `null` | Client chưa cấp nguồn usage đáng tin | Đúng theo thiết kế — không bịa số; `telemetry_quality=partial` |
|
||||
| `bridge doctor` báo gate missing | Repo chưa adopt core đầy đủ | Chạy lại DevKit install core |

# CASAN Agentic Client — Mô hình bảo mật & giới hạn bypass (Plan-20)
|
||||
|
||||
Tài liệu này nêu rõ **CASAN đảm bảo gì và không đảm bảo gì** khi developer gõ
|
||||
prompt trực tiếp trong một agentic client (Claude Code, Codex, VS Code). Mục tiêu
|
||||
là không dùng từ “bắt buộc tuyệt đối” sai mức: một số tuyến chỉ là guardrail theo
|
||||
project, có thể bị người có quyền sửa cấu hình bypass.
|
||||
|
||||
Liên quan:
|
||||
[Plan-20 §3](../plans/CASAN_PLAN_20_AGENTIC_CLIENT_INTEGRATION.md) ·
|
||||
[Spike-20 §9](../spikes/CASAN_SPIKE_20_AGENTIC_CLIENT_HOOKS.md).
|
||||
|
||||
## 1. Certification strength — bốn mức, không gộp
|
||||
|
||||
| Strength | Ý nghĩa | Cam kết | Bypass |
|
||||
|---|---|---|---|
|
||||
| `casan_owned` | Launcher/SDK/Chat Participant do CASAN điều khiển toàn vòng đời | Mạnh nhất trong local client | Rất khó với người dùng thường |
|
||||
| `managed_hook` | Hook/policy được tổ chức pin, user không tắt được | Guardrail tổ chức | Cần quyền quản trị môi trường |
|
||||
| `project_hook` | Hook commit trong repo, user trust project | Guardrail theo project | **Có thể bypass** bởi người sửa/tắt config |
|
||||
| `observed_only` | Chỉ telemetry, không đủ admission/tool gate | Không certified | N/A |
|
||||
|
||||
UI và export H6 **không** được gộp bốn mức trên thành một nhãn `pass`. Turn ở
|
||||
`observed_only` không bao giờ hiển thị `certified`.
|
||||
|
||||
## 2. Điều kiện tối thiểu để một turn được certified
|
||||
|
||||
1. Có `admission_id` hợp lệ, còn hạn (TTL), gắn đúng project root canonical và
|
||||
session/turn.
|
||||
2. Mọi side-effect tool trong coverage đã công bố đều qua `pre-tool`.
|
||||
3. Enforcement mode = `enforce` và certification strength ∈
|
||||
{`project_hook`, `managed_hook`, `casan_owned`}.
|
||||
4. Không có tín hiệu bypass coverage (ví dụ tool cross-project, tool ngoài
|
||||
coverage).
|
||||
5. `finalize` chạy đúng một lần và các control kết thúc không đánh flag.
|
||||
|
||||
Nếu bất kỳ điều kiện nào thiếu → turn là **non-certified**. Bridge fail-closed:
|
||||
khi không quyết định được trong internal timeout → block/deny.
|
||||
|
||||
## 3. Những gì CASAN KHÔNG hứa
|
||||
|
||||
- **Không** chặn được mọi prompt trong mọi AI extension bên thứ ba.
|
||||
- **Không** coi `project_hook` là security boundary tuyệt đối khi user có quyền
|
||||
sửa/tắt `.claude/settings.json` hoặc `.codex/hooks.json`.
|
||||
- **Không** gọi model lần hai từ hook để “chạy lại qua CASAN”.
|
||||
- **Không** suy diễn token/cost khi client không cấp nguồn tin cậy — số thiếu là
|
||||
`null` kèm warning, không phải `0`.
|
||||
- Codex tool hooks là guardrail, **không** phủ 100% hosted/specialized tools; turn
|
||||
dùng tool ngoài coverage bị hạ cấp, không certified.
|
||||
|
||||
## 4. Threat model đã kiểm thử
|
||||
|
||||
Suite `tests/phase-agentic-bridge-tests.sh` (Spike-20 C1–C12 + threat) kiểm:
|
||||
|
||||
| Mối đe dọa | Phòng thủ | Test |
|
||||
|---|---|---|
|
||||
| Side-effect không admission | Deny fail-closed | C4 |
|
||||
| Replay admission hết hạn | TTL check → deny | C5 |
|
||||
| Dùng lại admission khác project | Project binding → deny + bypass_signal | C5, THREAT bypass |
|
||||
| Prompt injection | H4 admission scan → block trước model | C2 |
|
||||
| Tamper `admission_id` (path traversal) | Chỉ chấp nhận uuid hex, chặn `..` | THREAT tamper |
|
||||
| Bridge/hook timeout | Internal timeout ngắn hơn outer → block/deny; ghi H6 failure | C6 |
|
||||
| Outer hook timeout (fail-open của client) | Side-effect vẫn bị `pre-tool` deny nếu thiếu admission | C7/C4 |
|
||||
| Stop loop | finalize idempotent, `stop_hook_active` guard | C8/C9 |
|
||||
| Secret/tool output lọt log | Redact + chỉ lưu hash, không lưu raw prompt/output | C11 |
|
||||
| Cost hiding (bịa số 0) | Missing → null + `telemetry_quality` | C10 |
|
||||
| Certified giả ở observe mode | Observe luôn `observed_only`, không certified | THREAT observe |
|
||||
|
||||
## 5. Contract dữ liệu & privacy
|
||||
|
||||
- State ở `.specify/state/agentic-sessions/`, ghi atomic + lock per-turn.
|
||||
- **Không** dùng raw prompt làm key; dùng salted hash + `turn_id` opaque.
|
||||
- Admission có TTL, project root canonical, và session binding.
|
||||
- **Không** ghi secret/credential hoặc toàn bộ tool output vào audit; evidence chỉ
|
||||
giữ bản redact + hash.
|
||||
- Mỗi record mang `schema_version`, `trace_id`, `project_id`, `client`,
|
||||
`client_version`, `integration_mode`, `certification_strength`, `occurred_at`.
|
||||
|
||||
## 6. Khi cần enforcement mạnh
|
||||
|
||||
Absolute enforcement cần `casan_owned` hoặc `managed_hook`:
|
||||
|
||||
- **managed_hook:** pin hook/policy qua managed environment/MDM/requirements; user
|
||||
không tắt được. Đặt `CASAN_AGENTIC_INTEGRATION_MODE=managed_hook` qua môi trường
|
||||
quản trị, **không** commit trong repo.
|
||||
- **casan_owned:** dùng launcher/SDK/Chat Participant do CASAN sở hữu toàn bộ vòng
|
||||
đời (ví dụ `@casan` VS Code Chat Participant — tuyến CASAN-owned, không phải
|
||||
global interceptor cho mọi prompt Copilot).
|
||||
|
||||
Plan-20 **không** quảng bá `project_hook` như một sandbox tuyệt đối.
|
||||
|
||||
## 7. Rollout & rollback
|
||||
|
||||
- Feature flags: `CASAN_AGENTIC_BRIDGE_ENABLED`,
|
||||
`CASAN_AGENTIC_ENFORCEMENT_MODE`, `CASAN_AGENTIC_CLIENT_ALLOWLIST`.
|
||||
- Bắt đầu `observe`, sau đó `enforce` trong pilot; production default chỉ đổi sau
|
||||
exit gate.
|
||||
- Trace sinh trong observe mode luôn `observed_only`, **không** retroactively
|
||||
certified.
|
||||
- Rollback chỉ tắt adapter; `bin/casan-chat` và core H1→H7 hiện tại vẫn hoạt động.

||||
- **VS Code / extension**: chưa black-box trên client thật; `@casan` Chat Participant (Wave 4)

# CASAN Claude Code adoption template (Plan-20)
|
||||
|
||||
Drop `settings.json` into the target repo as `.claude/settings.json` (the
|
||||
installer does this). It wires the four Claude Code lifecycle hooks
|
||||
(`UserPromptSubmit`, `PreToolUse`, `PostToolUse`, `Stop`) to the CASAN agentic
|
||||
bridge so a developer can type prompts normally while every certified turn still
|
||||
carries an H1→H7 trace and an H6 record.
|
||||
|
||||
- The hook command resolves the repo root via `$CLAUDE_PROJECT_DIR`, so **no
|
||||
machine-specific path is committed**.
|
||||
- It invokes `packages/casan-harness/adapters/claude-code/claude_hook.py`, a thin
|
||||
renderer that calls the core bridge. The bridge **never runs a model** — Claude
|
||||
remains the sole model executor (single-model invariant).
|
||||
- This is a **`project_hook`** integration: strong for a trusted project, but a
|
||||
member who can edit `.claude/settings.json` can disable it. For organization
|
||||
enforcement use a managed/pinned deployment (`managed_hook`) — see
|
||||
`docs/casan/CASAN_AGENTIC_CLIENT_SECURITY.md`.
|
||||
|
||||
## Install (cross-platform)
|

||||
```bash
|
||||
packages/casan-devkit/install.sh --target <repo> --project <id>
|

# CASAN Codex adoption template (Plan-20)
|
||||
|
||||
Drop `hooks.json` → `.codex/hooks.json` and merge `config.toml` into
|
||||
`.codex/config.toml` in the target repo (the installer does this). It wires the
|
||||
Codex lifecycle hooks to the CASAN agentic bridge via the thin renderer
|
||||
`packages/casan-harness/adapters/codex/codex_hook.py`.
|
||||
|
||||
Important Codex-specific facts (Spike-20 §4.2):
|
||||
|
||||
- **Trust review is mandatory.** Codex loads project-local hooks only after the
|
||||
user accepts a trust prompt. Run `casan doctor --client codex` (or the bridge
|
||||
`doctor` op) to confirm the trust/onboarding state — it is never hidden from a
|
||||
member.
|
||||
- **Tool hooks are a guardrail, not a complete boundary.** Hosted/specialized
|
||||
tools may fall outside hook coverage; a turn that uses an uncovered tool is
|
||||
**downgraded** (non-certified), not silently certified.
|
||||
- **Token/cost source is not assumed.** Unless Codex supplies a stable usage
|
||||
source, H6 records the number as `null` with `telemetry_quality=partial` — it
|
||||
is never invented (Spike-20 X6).
|
||||
- For enterprise enforcement, pin hooks via managed policy so a member cannot
|
||||
disable them and set `CASAN_AGENTIC_INTEGRATION_MODE=managed_hook` through the
|
||||
managed environment (not the committed config).
|
||||
|
||||
The command contract is stable (stdin JSON → exit 0 allow / exit 2 block); the
|
||||
exact Codex payload key names are pinned during the Wave-3 payload spike, which
|
||||
is why `codex_hook.py` reads several field aliases defensively.

<#
|
||||
.SYNOPSIS
|
||||
CASAN Plan-20 agentic-client installer for Windows PowerShell.
|
||||
|
||||
.DESCRIPTION
|
||||
Installs, verifies (doctor) or removes the CASAN agentic-client integration
|
||||
(Claude Code and/or Codex project hooks) in a target repository — from a
|
||||
clean clone, with NO manual file copying. Every created file is recorded in a
|
||||
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.
|
||||

||||

"""Claude Code adapter for the CASAN agentic bridge (Plan-20, Wave 1).
|
||||
|
||||
Thin renderer only: it translates Claude Code lifecycle hook JSON (on stdin) into
|
||||
the client-agnostic bridge contract, calls the core bridge, and renders the bridge
|
||||
response back into Claude-native hook output. The core bridge stays ignorant of
|
||||
Claude's JSON shape (Plan-20 §4 "Hook response renderer tách theo adapter").
|
||||
|
||||
Wire-up in `.claude/settings.json` (see settings.template.json in this folder):
|

|
||||
UserPromptSubmit -> claude_hook.py --event UserPromptSubmit
|
||||
PreToolUse -> claude_hook.py --event PreToolUse
|
||||
PostToolUse -> claude_hook.py --event PostToolUse
|
||||
Stop -> claude_hook.py --event Stop
|
||||
|

The event may also be taken from the `hook_event_name` field Claude includes in
|
||||
the payload, so `--event` is optional.
|
||||
|
||||
Claude hook contracts honored here:
|
||||
* UserPromptSubmit: `{"decision":"block","reason":...}` blocks the prompt;
|
||||
`hookSpecificOutput.additionalContext` injects extra context on allow.
|
||||
* PreToolUse: `hookSpecificOutput.permissionDecision` = allow|deny|ask.
|
||||
* PostToolUse / Stop: observational; Stop finalizes exactly once and guards
|

"""Codex adapter for the CASAN agentic bridge (Plan-20, Wave 3).
|
||||
|
||||
Thin renderer that maps Codex lifecycle hook payloads (on stdin) into the
|
||||
client-agnostic bridge contract and renders the response back. It reuses the
|
||||
core bridge module so the bridge never learns Codex's JSON shape.
|
||||
|
||||
Codex project hooks load only AFTER a trust review (Spike-20 §4.2) — the devkit
|
||||
`doctor` surfaces the trust/onboarding state so this is never hidden from a
|
||||
member. Codex tool hooks are a guardrail, not a complete boundary: a turn that
|
||||
uses a hosted/specialized tool outside hook coverage is DOWNGRADED, not
|
||||
silently certified.
|
||||
|
||||
Output contract (kept portable across Codex versions, which is why the exact
|
||||
field mapping is a Wave-3 experiment): a decision JSON on stdout AND an exit
|
||||
code — 0 = allow, 2 = block/deny — so a host that reads either signal fails
|
||||
closed the same way. Field names are accepted defensively (tool_name|tool,
|
||||
cwd|project, session_id|session) to absorb payload drift.
