+
+### Session 150 — OPAD Doctrine Documents v2.4.0
+
+**Goal:** Create the 5 foundational OPAD (Off-Path Active Defense) doctrinal documents for SecuBox-Deb migration to passive observation + packet injection architecture.
+
+**Reference:** CM-WALL-OPAD-2026-05
+
+**Architecture Overview:**
+- **OPAD Principle:** SecuBox observes traffic passively (port mirroring) and injects packets to neutralize threats, never sits in the data path
+- **4 Injection Primitives:** DNS-R (99%), DHCP-R (95%), RST-I (90%), ARP-R (98%)
+- **8 Invariants (INV-01 to INV-08):** Fail-silent, no forwarding, zero WAN surface, etc.
+- **3-Prong Profile:** Observation / Injection / Policy configuration structure
+
+**Files Created:**
+
+| File | Lines | Description |
+|------|-------|-------------|
+| `doctrine/opad/OPAD.md` | 671 | Core doctrine, principles, invariants, injection specs |
+| `doctrine/opad/CSPN.matrix.md` | 569 | ANSSI threat × capability matrix (36 threats, 72% coverage) |
+| `doctrine/opad/OPAD-OPERATIONS.md` | 948 | Operational guide, troubleshooting, 4R rollback |
+| `schemas/opad-profile.schema.json` | 365 | JSON Schema draft-07 for profile validation |
+| `common/secubox_core/opad/models.py` | 400 | Pydantic v2 models (OPADProfile, configs) |
+| `common/secubox_core/opad/__init__.py` | 85 | Package exports |
+| `tests/test_opad_schema.py` | 374 | 18 tests (JSON Schema + Pydantic equivalence) |
+| **Total** | **3412** | |
+
+**Technical Notes:**
+- Pydantic v2 syntax: `@field_validator`, `ConfigDict`, `model_json_schema()`
+- JSON Schema draft-07 with `$defs` for reusable definitions
+- MAC address validation: `^([0-9A-Fa-f]{2}:){5}[0-9A-Fa-f]{2}$`
+- Success rate constraints: 0.90 ≤ rate ≤ 1.0 for injection primitives
+
+**Tests:** 18 passed (0.13s)
+- JSON Schema Draft7 validation
+- Pydantic model equivalence
+- MAC address format validation
+- Success rate bounds checking
+- Policy rule priority range (0-9999)
+
+**Commits:** Cherry-picked to `feature/eye-remote-auto-mode`

+
+## ✅ Session 149: Mode Control API & Dashboard Integration
+
+### Objective
+Add web-based mode control to the Eye Remote admin dashboard for safer manual gadget switching.
+
+### Completed
+- **Mode Control API** (`mode_api.py`):
+  - HTTP API on port 8081 (8080 used by CrowdSec)
+  - `GET /api/status`: Current gadget mode and functions
+  - `POST /api/switch/<mode>`: Switch composite/network/storage/silent/hid
+  - `GET /health`: Health check endpoint
+  - `GET /metrics`: System metrics (CPU, RAM, disk, temp, load, uptime)
+  - HTML control panel with mode buttons
+
+- **Dashboard Integration** (`admin.gk2.secubox.in/eye-remote/`):
+  - USB Gadget Mode card with current status
+  - Mode switch buttons (COMPOSITE, NETWORK, STORAGE, SILENT)
+  - Live metrics display (CPU, RAM, Temp, Uptime)
+  - Auto-refresh every 10 seconds
+
+- **Infrastructure**:
+  - Systemd service `secubox-mode-api.service` on Pi
+  - Nginx proxy `/eye-remote/mode/` → `http://10.55.0.2:8081/`
+  - Nginx proxy `/api/v1/eye-remote/` → `http://10.55.0.2:8081/`
+
+### Commits
+- `462d2712` — feat(eye-remote): Add Mode Control API with metrics endpoint
+
+### Files Changed
+| File | Change |
+|------|--------|
+| `remote-ui/round/agent/api/mode_api.py` | NEW: Mode Control API with metrics |
+| `remote-ui/round/agent/auto_mode_controller.py` | Minor improvements |
+| `.gitignore` | Exclude backup images |
+
+### Deployed To
+- Pi Zero W: `/home/pi/eye-remote/agent/api/mode_api.py`
+- MOCHAbin: nginx config updated for port 8081
+
+### Current State
+- ✅ Mode API running on Pi (port 8081)
+- ✅ Dashboard shows Pi metrics and connection status
+- ✅ Mode control buttons integrated in admin panel
+- ✅ Health and metrics endpoints working
+- ✅ Composite mode active (ECM+ACM+RNDIS+Storage)
+
+### Next Steps
+1. ⬜ Test mode switching from web UI
+2. ⬜ Add HID mode button to dashboard
+3. ⬜ Create new backup image v2.2.2 with mode API
+4. ⬜ Investigate gadget crash root cause during mode switch
+
+---
+
+## ✅ Session 148: Eye Remote Auto-Mode Stability
+
+### Problem
+- Auto-mode controller caused USB gadget crashes when switching modes
+- Mode detection not working (always saw "none" instead of COMPOSITE)
+- Multiple display processes could run simultaneously
+- Network probing triggered unnecessary mode switches
+
+### Solution Implemented
+- **Mode Detection**: Added `_detect_current_mode()` to read configfs functions
+- **Smart Probing**: Check network connectivity BEFORE attempting mode switches
+- **Single Instance**: PID file locking in `fallback_manager.py`
+- **Storage Recovery**: If storage not mounted after 30s, switch back to composite
+
+### Commits
+- `b859817e` — fix(eye-remote): Improve auto-mode stability and single-instance display
+
+### Files Changed
+| File | Change |
+|------|--------|
+| `agent/auto_mode_controller.py` | Mode detection, smart probing, storage recovery |
+| `agent/display/fallback/fallback_manager.py` | PID lock for single instance |
+| `files/etc/secubox/eye-remote/gadget-setup.sh` | Lock file, cooldown safeguards |
+
+### Status
+- ✅ Completed — mode detection and stability fixes deployed

+# APT Public Repo Staging — Design
+
+**Date:** 2026-05-12
+**Author:** Gandalf (CyberMind), with Claude
+**Status:** Draft for approval
+**Targets:** `apt.secubox.in` (production), `bookworm` suite, `arm64` (mochabin/Armada 7040) + `amd64`
+
+## Goal
+
+Produce a fully signed, validated APT repository tree under `output/repo/`
+containing both `amd64` and `arm64` SecuBox packages for the `bookworm` suite.
+The tree is ready to be `rsync`-ed to `apt.secubox.in` out-of-band by the user.
+
+This run **does not** touch the production server, **does not** request TLS
+certificates, and **does not** push any data over the network. It produces
+artifacts (signed repo tree, nginx vhost, deploy recipe) the user pushes when
+satisfied.
+
+## Non-goals
+
+- Provisioning the `apt.secubox.in` server itself (handled by
+  [repo/scripts/setup-repo-server.sh](../../../repo/scripts/setup-repo-server.sh)
+  when the user runs it on the VPS).
+- Issuing the TLS certificate (certbot runs on the production host, post-rsync).
+- Building anything for `trixie` (placeholder section only).
+- Cross-building anything that genuinely needs native compilation against
+  ARM-only libraries — fall back to a halt with a clear message.
+
+## Inputs
+
+| Input | Source |
+|-------|--------|
+| Package set per tier | `secubox gen --tier {tier-lite,tier-standard,tier-pro} --out manifests/` |
+| Build script | [`scripts/build-packages.sh`](../../../scripts/build-packages.sh) `bookworm <arch>` |
+| GPG key | `~/.gnupg/secubox/` (persistent across runs) |
+| Reprepro driver | `secubox apt {init,publish,check}` via [`cmd/secubox/cmd/apt_server.go`](../../../cmd/secubox/cmd/apt_server.go) |
+| Install script | [`repo/install.sh`](../../../repo/install.sh) |

+
+## Architecture
+
+### Component 1 — GPG bootstrap
+
+**Lives at:** `~/.gnupg/secubox/` (persistent home, **outside** the repo tree).
+**Driver:** [`repo/scripts/generate-gpg-key.sh`](../../../repo/scripts/generate-gpg-key.sh)
+with `GPG_HOME=~/.gnupg/secubox` and `EXPORT_DIR=output/repo`.
+
+Key parameters (already in script): RSA 4096 + 4096 subkey, no passphrase,
+`packages@secubox.in`, no expiry. Idempotent — exits early if a key for that
+UID already exists in the keyring.
+
+Produces:
+- `output/repo/secubox-keyring.gpg` (ASCII-armored public key)
+- `output/repo/FINGERPRINT.txt` (long fingerprint, used by `SignWith:`)
+
+### Component 2 — Tier resolution
+
+**Driver:** `secubox gen --tier <tier> --board mochabin --out manifests/<tier>/`
+
+For each tier in order `base → tier-lite → tier-standard → tier-pro`, resolve
+the package set from [`profiles/`](../../../profiles/) via the Go profile
+engine ([`cmd/secubox/internal/profile/`](../../../cmd/secubox/internal/profile/)).
+
+Tier 0 (base) is **implicit** — there is no `--tier base` flag. We build it
+directly as the hardcoded set `{secubox-core, secubox-hub}`. Higher tiers are
+resolved by `secubox gen` from `profiles/{tier-lite,tier-standard,tier-pro}.yaml`
+which inherit transitively from `base.yaml`. Output is a manifest directory
+per tier; the orchestrator extracts the `packages.required` list as the build
+filter.
+
+### Component 3 — Layered cross-build
+
+**Driver:** [`scripts/build-packages.sh`](../../../scripts/build-packages.sh) with a `--filter <manifest>` flag
+(new flag; passes filter through to the existing `PACKAGES=` array).
+
+For each tier T in `[base, lite, standard, pro]`:
+1. Run `build-packages.sh bookworm arm64 --filter manifests/tier-T.json`
+2. Run `build-packages.sh bookworm amd64 --filter manifests/tier-T.json`
+3. Collect `output/debs/*_arm64.deb`, `*_amd64.deb`, `*_all.deb` matching the
+   filter. The `_all` packages only need to be built once (in the arm64 pass);
+   amd64 pass skips packages with `Architecture: all` already built.
+4. If **any** package in tier T fails, halt the pipeline. Tiers T-1 and lower
+   are already published and remain usable. Record the failure in
+   `MANIFEST.txt` and exit non-zero.
+
+Cross-build dependencies (`crossbuild-essential-arm64`, `qemu-user-static`
+for any `_arm64.deb` running maintainer scripts during build) are checked up
+front; missing → halt with apt-install hint.
+
+### Component 4 — Reprepro repository
+
+**Driver:** `secubox apt init --base output/repo` then
+`secubox apt publish output/debs/...`.
+
+`conf/distributions` (production identity):
+```
+Origin: SecuBox
+Label: SecuBox
+Suite: bookworm
+Codename: bookworm
+Version: 12.0
+Architectures: arm64 amd64 source
+Components: main
+Description: SecuBox Debian packages for Armada/x86_64
+SignWith: <fingerprint from FINGERPRINT.txt>
+Contents: percomponent nocompatsymlink
+```
+
+A `trixie` block is included with the same shape, but no packages are
+published into it in this design.
+
+`conf/options`:
+```
+verbose
+basedir <abs path>/output/repo
+gnupghome <abs path>/.gnupg/secubox
+```
+
+`reprepro` requires the `gnupghome` to be an absolute path; we resolve `~`
+before writing.
+
+After each tier publish: `secubox apt check` (wraps `reprepro check`). Clean
+output is required before moving to the next tier.
+
+### Component 5 — Deploy artifacts (no network)
+
+`output/repo/nginx-apt.conf`:
+- `server_name apt.secubox.in;`
+- `root /var/www/apt.secubox.in;`
+- ACME challenge location `/.well-known/acme-challenge/`
+- MIME types: `application/vnd.debian.binary-package` for `.deb`,
+  `application/pgp-keys` for `.gpg`
+- `autoindex on` for `/dists/` and `/pool/`
+- Listen 80 only (TLS added by certbot in-place on the server)
+
+`output/repo/DEPLOY.md` documents:
+1. `rsync -avz --delete output/repo/ deploy@apt.secubox.in:/var/www/apt.secubox.in/`
+2. `ssh deploy@apt.secubox.in sudo cp /var/www/apt.secubox.in/nginx-apt.conf /etc/nginx/sites-available/apt.secubox.in`
+3. `ssh apt.secubox.in sudo certbot --nginx -d apt.secubox.in --non-interactive --agree-tos -m packages@secubox.in`
+4. Post-deploy: `openssl s_client -servername apt.secubox.in -connect apt.secubox.in:443 </dev/null 2>/dev/null | openssl x509 -noout -ext subjectAltName` — must list `DNS:apt.secubox.in`.
+
+### Component 6 — Validation gate
+
+Before printing "done":
+
+1. `reprepro -b output/repo check` — must be clean.
+2. `gpg --homedir ~/.gnupg/secubox --verify output/repo/dists/bookworm/InRelease`
+   — must report `Good signature` from the SecuBox UID.
+3. Optional but recommended: debootstrap a throwaway `bookworm` chroot under
+   `output/test-chroot/`, mount nothing, add `deb [trusted=no signed-by=...] file://<abs>/output/repo/ bookworm main` to `sources.list.d`, run
+   `apt-get update` inside the chroot. Must succeed without warnings.
+4. Write `output/repo/MANIFEST.txt` with the per-tier × per-arch table and
+   the full `dpkg -I` summary of every published .deb.
+
+If any step fails, the pipeline exits non-zero and the run is considered
+incomplete — but `output/repo/` is left in place for the user to inspect.
+
+## Error handling
+
+| Failure | Behavior |
+|---------|----------|
+| Missing cross-build dep | Halt before any build, print exact `apt install` command |
+| Single package build fails in tier T | Record in `MANIFEST.txt`, halt at end of tier T (lower tiers stay published) |
+| Reprepro check fails | Halt; do not advance to next tier |
+| GPG signature verify fails | Halt; this means the key is wrong or the repo is corrupt |
+| Chroot validation fails | Warning, not halt — could be a local env issue, not a repo bug |
+
+All halts are non-zero exit with a one-line summary plus a pointer to the
+detailed log under `output/build.log`.
+
+## Testing
+
+This work is operational (it produces an artifact); no unit tests are added.
+Instead the **chroot validation step is the test** — if a fresh `bookworm`
+chroot can `apt update` against the staged repo, the artifact works.
+
+For regressions, the manifest file is diffable: re-running with a new package
+version produces a `MANIFEST.txt` that can be `diff`-ed against the last good
+build.
+
+## Open questions
+
+None blocking. The mochabin board profile under
+[`board/mochabin/`](../../../board/mochabin/) is already declared (Armada 7040,
+arm64); no additional board work is needed for the publish step.
+
+## Licensing
+
+| Layer | License | Notes |
+|-------|---------|-------|
+| SecuBox-Deb source & packages | CMSD-1.0 (CyberMind Source-Disclosed) / ANSSI CSPN candidate | Per [`.claude/CLAUDE.md`](../../../.claude/CLAUDE.md). Each `.deb` carries `debian/copyright` declaring this. |
+| Package signing key | SecuBox internal | UID `SecuBox Package Signing Key <packages@secubox.in>`. Not third-party; do not cross-sign. |
+| Repository tooling (reprepro, nginx, certbot) | GPL / BSD / Apache (upstream) | Used as-is from Debian; no redistribution. |
+| `install.sh` (served from repo root) | Proprietary / CyberMind | Header credits `https://github.com/gkerma/secubox-deb`. Includes terms-of-service hint pointing to `https://secubox.in/terms`. |
+| TLS certificate | Let's Encrypt (ISRG) | Issued on the production host via certbot; subject CN = `apt.secubox.in`. |
+| Public GPG key file | Proprietary distribution, free to redistribute the public half | Served at `/secubox-keyring.gpg`; SHA256 published in `FINGERPRINT.txt`. |
+
+The staged tree MUST include:
+
+- `output/repo/LICENCE-CMSD-1.0.md` — verbatim copy of the project root
+  [`LICENCE-CMSD-1.0.md`](../../../LICENCE-CMSD-1.0.md) (authoritative French
+  text).
+- `output/repo/LICENSE-CMSD-1.0.en.md` — verbatim copy of the project root
+  [`LICENSE-CMSD-1.0.en.md`](../../../LICENSE-CMSD-1.0.en.md) (informative
+  English translation).
+
+Both served at `https://apt.secubox.in/LICENCE-CMSD-1.0.md` and
+`https://apt.secubox.in/LICENSE-CMSD-1.0.en.md`. The
+[`install.sh`](../../../repo/install.sh) script references the French file
+(authoritative) before any apt operation so users see the terms before
+adding the repo. Per Article 13.5 of the license, the French text prevails
+in any conflict.
+
+Validation gate adds:
+
+- `output/repo/LICENCE-CMSD-1.0.md` and `output/repo/LICENSE-CMSD-1.0.en.md`
+  exist and byte-match the project root copies.
+- `output/repo/FINGERPRINT.txt` contains exactly one fingerprint matching the
+  key used by `SignWith:`.
+
+## File-level changes
+
+| Action | File | Purpose |
+|--------|------|---------|
+| Modify | `scripts/build-packages.sh` | Add `--filter <manifest.json>` flag |
+| Create | `scripts/stage-apt-repo.sh` | Orchestrator: tiers × archs × reprepro |
+| Create | `scripts/render-deploy-artifacts.sh` | Generate `nginx-apt.conf` + `DEPLOY.md` |
+| Create | `scripts/validate-staged-repo.sh` | reprepro check + gpg verify + chroot test |
+| Modify | `.gitignore` | Ignore `output/repo/db/`, `output/repo/pool/`, `output/test-chroot/` |
+| Create | `output/repo/.gitkeep` | Keep dir structure |
+
+The `secubox apt` Go CLI is **not** modified — we only call its existing
+subcommands.

+# Design — CMSD-1.0 License Headers Across the Codebase
+
+**Date:** 2026-05-12
+**Status:** Approved by user (sections 1–5), pending plan
+**Author:** Claude (brainstormed with @CyberMind-FR)
+**Tracking:** GitHub Issue TBD (created at start of Phase A)
+
+---
+
+## 1. Goal
+
+Add the CyberMind Source-Disclosed License v1.0 (CMSD-1.0) SPDX header to every first-party source file in the `secubox-deb` repository, and keep it that way going forward with a CI check.
+
+Today the canonical header template lives in `LICENSING.md` (lines 70–75) but **zero of ~2,170 first-party code files** carry it. This design closes that gap mechanically, idempotently, and reviewably.
+
+## 2. Scope
+
+### 2.1 File types in scope
+
+| Extension(s) | Comment style | Count (approx.) |
+|---|---|---|
+| `.py` | `#` line comments | 865 |
+| `.sh` | `#` line comments | 122 |
+| `.js`, `.mjs`, `.ts` | `//` line comments | 613 |
+| `.c`, `.h` | `/* ... */` block (C89-safe) | 86 |
+| `.css` | `/* ... */` block | 100 |
+| `.html` | `<!-- ... -->` block | 384 |
+| `.md` | `<!-- ... -->` block | (many) |
+| `.toml`, `.yaml`, `.yml`, `.conf` | `#` line comments | (some) |
+
+JSON is **out of scope** (no comment syntax).
+
+### 2.2 Paths excluded (skip-list)
+
+Hard-coded directory prefixes the walker never descends into:
+
+- `kernel-build/`, `redroid/`, `tools/Tow-Boot/` — vendor/upstream code with its own licenses
+- `output/`, `cache/`, `backups/`, `apt/`, `repo/` — generated/build artifacts
+- `node_modules/`, `.venv/`, `.git/`, `__pycache__/`, `dist/`, `build/` — tool-managed trees
+
+Glob excludes:
+
+- `*.min.js`, `*.min.css` — minified bundles
+- `package-lock.json`, `*.lock` — lockfiles
+- Any file whose first 10 lines already contain `SPDX-License-Identifier: ` followed by **something other than** `LicenseRef-CMSD-1.0` → skipped with a warning to stderr (do not overwrite third-party licenses)
+
+### 2.3 Out of scope (explicitly)
+
+- Modifying the CMSD-1.0 license terms themselves
+- Adding the header to the LICENSE files (they already define the license)
+- Re-licensing any third-party code
+- A "remove header" mode — not needed
+
+## 3. Header content
+
+The canonical 4-line header, parameterized by language comment marker (`<CM>`):
+
+```
+<CM> SPDX-License-Identifier: LicenseRef-CMSD-1.0
+<CM> Copyright (c) 2026 CyberMind — Gérald Kerma <devel@cybermind.fr>
+<CM> Source-Disclosed License — All rights reserved except as expressly granted.
+<CM> See LICENCE-CMSD-1.0.md for terms.
+```
+
+Followed by **one blank line**, then the file's pre-existing content.
+
+### 3.1 Per-language rendering
+
+| Language | Rendered as |
+|---|---|
+| Python, Bash, YAML, TOML, conf | Four `# ` prefixed lines |
+| JS, TS, MJS | Four `// ` prefixed lines |
+| C, H | Single `/* ... */` block, internal lines prefixed ` * ` |
+| CSS | Single `/* ... */` block, internal lines prefixed ` * ` |
+| HTML, Markdown | Single `<!-- ... -->` block, internal lines indented 2 spaces |
+
+### 3.2 Placement rules
+
+The header MUST appear at the top of the file, with the following exceptions:
+
+| File type | Header goes... |
+|---|---|
+| Python with `#!` shebang | Immediately after the shebang line |
+| Python with `# -*- coding: ... -*-` | Immediately after the encoding declaration |
+| Bash with `#!` shebang | Immediately after the shebang line |
+| JS/TS with `"use strict"` or top-level directive | Above the directive (header at line 1) |
+| HTML with `<!DOCTYPE html>` | Immediately after the doctype, on its own line |
+| Markdown with YAML frontmatter `---` | Immediately after the closing `---` |
+| All others | Line 1 |
+
+## 4. The tool — `scripts/license-headers.py`
+
+Single-file Python 3.11+ utility, **stdlib only** (`argparse`, `pathlib`, `re`, `sys`).
+
+### 4.1 CLI
+
+```
+license-headers.py --check [PATHS...]    # exit 0 if all good, 1 if missing
+license-headers.py --fix   [PATHS...]    # add headers in place; idempotent
+license-headers.py --list  [PATHS...]    # dry-run: list files that would be modified
+license-headers.py --diff  [PATHS...]    # unified diff per file, no writes
+```
+
+- Default `PATHS` = repo root (cwd-relative).
+- The repo root is detected by walking up from cwd to the nearest `.git/`.
+- Mode flags are mutually exclusive; exactly one is required.
+- During `--check`, the enrollment allowlist (see §5) constrains which paths are evaluated.
+
+### 4.2 Internal structure (~300 LOC, one file)
+
+| Component | Responsibility |
+|---|---|
+| `SKIP_DIRS: frozenset[str]` | Dirnames the walker prunes (§2.2 directory list) |
+| `SKIP_GLOBS: tuple[str, ...]` | Glob patterns for excluded files |
+| `LANG_TABLE: dict[str, LangSpec]` | Maps `.ext` → `(comment_style, placement_rule, header_renderer)` |
+| `detect_existing(text) -> Status` | Returns `MATCH` / `FOREIGN` / `NONE` based on first 10 lines |
+| `render_header(comment_style) -> str` | Builds the 4-line block for one language |
+| `apply(text, ext) -> str` | Pure function: input file content → output content with header inserted at correct position |
+| `walk(paths, enrolled) -> Iterator[Path]` | Yields in-scope files, honoring skip-list and enrollment allowlist |
+| `main()` | Argparse dispatch |
+
+### 4.3 Idempotence contract
+
+```
+apply(apply(text, ext), ext) == apply(text, ext)
+```
+
+Explicitly tested. Detection is based on matching the literal token `SPDX-License-Identifier: LicenseRef-CMSD-1.0` anywhere in the first 10 lines, tolerant of comment-marker variation and whitespace.
+
+### 4.4 Tests — `tests/test_license_headers.py` (pytest)
+
+1. `apply` is idempotent for every extension in `LANG_TABLE`.
+2. Shebang, doctype, frontmatter, and encoding declarations are preserved in their original position.
+3. Foreign SPDX (e.g., `GPL-2.0-or-later`, `MIT`) → file returned unchanged; warning emitted.
+4. Existing CMSD header is not duplicated, regardless of comment style variation.
+5. `--check` exits 1 when any in-scope file lacks the header.
+6. `SKIP_DIRS` are pruned: a file under `kernel-build/` is never yielded by `walk`.
+
+All tests run without filesystem side effects (use `tmp_path` fixtures and string inputs to `apply`).
+
+## 5. CI integration
+
+### 5.1 Workflow — `.github/workflows/license-check.yml`
+
+```yaml
+name: License Headers
+on:
+  pull_request:
+  push:
+    branches: [master]
+jobs:
+  check:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      - uses: actions/setup-python@v5
+        with: { python-version: '3.11' }
+      - run: python3 scripts/license-headers.py --check
+```
+
+No `pip install`; runs in <10s.
+
+### 5.2 Enrollment allowlist
+
+To avoid breaking CI before Phase B is complete, the `--check` mode reads an **enrollment allowlist** at `scripts/license-headers-enrolled.txt`:
+
+- One glob pattern per line (e.g., `common/**`, `packages/secubox-hub/**`).
+- Lines starting with `#` are comments.
+- Empty/missing file → nothing is enforced (Phase A initial state).
+- File contains `**` only → repo-wide enforcement (Phase C final state).
+- File deleted at end of Phase C; tool then defaults to repo-wide.
+
+Phase B PRs each add one line to this file as they enroll a path.
+
+### 5.3 Optional pre-commit hook
+
+Documented in `scripts/README.md`; not installed by default:
+
+```yaml
+- repo: local
+  hooks:
+    - id: license-headers
+      name: License Headers (CMSD-1.0)
+      entry: python3 scripts/license-headers.py --fix
+      language: system
+      pass_filenames: true
+```
+
+## 6. Rollout
+
+### 6.1 Phase A — Foundation (1 PR, GitHub Issue, label: `infra`)
+
+Deliverables:
+1. `scripts/license-headers.py` (the tool)
+2. `tests/test_license_headers.py` (unit tests)
+3. `.github/workflows/license-check.yml` (CI)
+4. `scripts/license-headers-enrolled.txt` (initial empty enrollment)
+5. `scripts/README.md` updated to document the tool and pre-commit hook
+6. `CLAUDE.md` Python and Bash convention examples updated to show the SPDX block above the existing docstring/shebang preamble (replaces the current "License: Proprietary / ANSSI CSPN candidate" line in the Python example)
+7. The tool's own files (`license-headers.py`, test file, workflow) carry the CMSD header (sanity check of `--fix`)
+
+CI passes because the enrollment allowlist is empty.
+
+### 6.2 Phase B — Per-package enrollment (~16 PRs, label: `migration`)
+
+One PR per scope, each PR:
+1. Runs `python3 scripts/license-headers.py --fix <path>`
+2. Adds `<path>/**` to `scripts/license-headers-enrolled.txt`
+3. Commits with message `chore(license): enroll <path> in CMSD header check (ref #NNN)`
+4. PR description summarizes file counts touched
+
+PR list:
+- 14 PRs for `packages/secubox-*` (one per package)
+- 1 PR for `common/` + `api/`
+- 1 PR for `scripts/` + `image/` + `board/` + top-level files (`*.py`, `*.sh` at root)
+- 1 PR for `docs/` + `.claude/` + Markdown files repo-wide
+- (Optional) 1 PR for commentable configs (`*.toml`, `*.yaml`, `*.conf` outside packages already covered)
+
+### 6.3 Phase C — Closure (1 PR, label: `infra`)
+
+1. Delete `scripts/license-headers-enrolled.txt`
+2. Update `LICENSING.md` with a note: *"All source files carry the CMSD-1.0 SPDX header; see `scripts/license-headers.py`."*
+3. Run `--check` repo-wide locally before merging.
+
+## 7. Verification
+
+### 7.1 Phase A smoke tests (before merging the PR)
+
+| # | Command | Expected |
+|---|---|---|
+| 1 | `python3 scripts/license-headers.py --diff common/secubox_core/auth.py` | Clean 5-line addition above the docstring |
+| 2 | `python3 scripts/license-headers.py --diff scripts/deploy.sh` | Header lands after `#!/usr/bin/env bash` |
+| 3 | `python3 scripts/license-headers.py --diff packages/secubox-hub/www/index.html` | Header lands after `<!DOCTYPE html>` |
+| 4 | Run `--fix` on a file, then `--fix` again | Second run produces no changes (idempotence) |
+| 5 | Create temp file with `# SPDX-License-Identifier: MIT` | Tool skips with stderr warning |
+| 6 | `pytest tests/test_license_headers.py` | All 6 tests pass |
+
+### 7.2 Per-PR verification in Phase B
+
+1. Reviewer eyeballs ~5 randomly-sampled files in the PR diff for correct placement.
+2. For Python packages with existing `pytest` suites: run the package's tests after applying headers — confirms no syntactic breakage.
+3. For Bash scripts touched: `bash -n <file>` for each, no syntax errors.
+4. CI's `--check` step passes (with the newly enrolled path).
+
+### 7.3 Phase C verification
+
+1. Locally: with the allowlist file removed, `python3 scripts/license-headers.py --check` exits 0.
+2. Create a deliberately header-less throwaway file → CI fails as expected → remove it before merging.
+
+## 8. Risks and mitigations
+
+| Risk | Mitigation |
+|---|---|
+| Header insertion breaks file syntax (e.g., HTML doctype, Bash shebang) | Placement rules in §3.2; tested case-by-case in §4.4 |
+| Third-party file accidentally gets re-licensed | Foreign SPDX detection skips and warns (§2.2) |

+# OPAD Doctrine Documents — Design Specification
+
+**Date** : 2026-05-12
+**Référence** : CM-WALL-OPAD-2026-05
+**Version** : 2.4.0
+**Auteur** : CyberMind / Claude Code
+**Statut** : Approuvé pour implémentation
+
+---
+
+## 1. Résumé exécutif
+
+Ce document spécifie la création des documents doctrinaux OPAD (Off-Path Active Defense) pour SecuBox-Deb v2.4.0. OPAD devient la doctrine canonique de sécurité, remplaçant l'approche IDGP in-path.
+
+### Doctrine en une ligne
+
+> La SecuBox n'est pas dans le chemin. Elle est à côté du chemin, et elle gagne des courses. Quand elle est là, elle protège par disruption ciblée. Quand elle n'est pas là, le réseau ne le remarque pas.
+
+### Livrables
+
+| # | Document | Chemin | Audience |
+|---|----------|--------|----------|
+| 1 | OPAD.md | `doctrine/opad/OPAD.md` | CSPN + équipe |
+| 2 | CSPN.matrix.md | `doctrine/opad/CSPN.matrix.md` | ANSSI |
+| 3 | opad-profile.schema.json | `schemas/opad-profile.schema.json` | Développeurs |

+
+## 2. Contexte et motivation
+
+### 2.1 Problème avec l'approche antérieure
+
+La doctrine IDGP (In-line Deep Guard Protection) place SecuBox dans le chemin de données :
+
+```
+[LAN] ←→ [SecuBox Bridge] ←→ [WAN]
+```
+
+**Violations identifiées** :
+- Crash SecuBox = rupture réseau totale
+- Latence ajoutée sur chaque paquet
+- Surface d'attaque étendue (SecuBox joignable)
+- Mode de défaillance non-silencieux
+
+### 2.2 Solution OPAD
+
+OPAD place SecuBox hors du chemin, en observation passive avec injection active :
+
+```
+[LAN] ←→ [Switch] ←→ [WAN]
+              ↑
+        [SecuBox] (observe + injecte)
+```
+
+**Garanties** :
+- Retrait physique = aucun impact
+- Latence zéro sur trafic normal
+- Surface d'attaque minimale
+- Fail-silent par design
+
+---
+
+## 3. Invariants OPAD
+
+Ces 8 invariants sont non-négociables et doivent être testés :
+
+| ID | Invariant | Test de vérification |
+|----|-----------|---------------------|
+| INV-01 | Retrait physique sans impact LAN↔WAN | Kill SecuBox, ping continue |
+| INV-02 | Aucun forwarding utilisateur via SecuBox | Inspection topologique |
+| INV-03 | Journalisation ALERTE·DÉPÔT systématique | Chaque injection = log signé |
+| INV-04 | Marquage OPAD_INJECT_LOST sur courses perdues | Simulation + vérification log |
+| INV-05 | Aucune réponse IP-active côté LAN en nominal | nmap depuis LAN = 0 réponse |
+| INV-06 | Surface d'attaque WAN nulle | Scan externe = 0 port ouvert |
+| INV-07 | Fail-silent par défaut | kill -9 = 0 impact trafic |
+| INV-08 | Escalade in-path révocable et explicite | Test escalade + révocation |
+
+---

+```
+
+### 4.2 Primitif DNS-R (DNS Race)
+
+**Objectif** : Répondre au client DNS avant le serveur légitime.
+
+**Mécanisme** :
+1. Observer DNS Query (UDP/53) en promiscuous
+2. Évaluer contre politique (domaine interdit ? device suspect ?)
+3. Si action requise : forger réponse DNS
+4. Injecter réponse avec TTL court
+5. Client accepte première réponse reçue
+
+**Paramètres** :
+```json
+{
+  "enabled": true,
+  "target_success_rate": 0.99,
+  "modes": ["nxdomain", "sinkhole", "redirect_captive"],
+  "sinkhole_ip": "127.0.0.1",
+  "ttl": 300
+}
+```
+
+**Taux de succès** : ≥ 99% (SecuBox plus proche du client que le serveur DNS)
+
+### 4.3 Primitif DHCP-R (DHCP Race)
+
+**Objectif** : Attribuer une IP de quarantaine avant le serveur DHCP légitime.
+
+**Mécanisme** :
+1. Observer DHCP DISCOVER (UDP/67-68)
+2. Si device non autorisé ou suspect
+3. Forger DHCP OFFER avec IP quarantaine
+4. Gateway pointe vers captive portal SecuBox
+5. Lease court (300s) pour réévaluation rapide
+
+**Paramètres** :
+```json
+{
+  "enabled": true,
+  "target_success_rate": 0.95,
+  "quarantine_pool": {
+    "start": "10.99.0.10",
+    "end": "10.99.0.250",
+    "lease_time": 300,
+    "gateway": "10.99.0.1"
+  }
+}
+```
+
+**Taux de succès** : ≥ 95%
+
+### 4.4 Primitif RST-I (TCP RST Injection)
+
+**Objectif** : Couper une connexion TCP établie par injection de RST.
+
+**Mécanisme** :
+1. Observer connexion TCP (SYN/ACK ou données)
+2. Si connexion vers C2 ou destination interdite
+3. Calculer sequence numbers valides
+4. Injecter RST vers les deux endpoints (double-ended)
+5. Connexion coupée des deux côtés
+
+**Paramètres** :
+```json
+{
+  "enabled": true,
+  "target_success_rate": 0.90,
+  "double_ended": true,
+  "timing_window_ms": 10
+}
+```
+
+**Taux de succès** : ≥ 90% (limité par fenêtre TCP et timing)
+
+### 4.5 Primitif ARP-R (ARP Redirect)
+
+**Objectif** : Rediriger le trafic d'un device vers captive portal.
+
+**Mécanisme** :
+1. Identifier device à rediriger (MAC)
+2. Envoyer Gratuitous ARP : "IP gateway = MAC SecuBox"
+3. Device envoie son trafic vers SecuBox captive
+4. Refresh périodique pour maintenir redirection
+5. Arrêt du refresh = retour à la normale automatique
+
+**Paramètres** :
+```json
+{
+  "enabled": true,
+  "target_success_rate": 0.98,
+  "refresh_interval_s": 30,
+  "captive_mac": "aa:bb:cc:dd:ee:ff"
+}
+```
+
+**Taux de succès** : ≥ 98% (sauf ARP statique côté client)
+

+## 1. Périmètre d'évaluation
+
+### 1.1 Composants inclus
+
+Cette matrice évalue les **capacités de protection active** du module **WALL** en mode **OPAD** (Off-Path Active Defense). Les composants suivants sont **dans le périmètre CSPN** :
+
+| Composant | Rôle | Module SecuBox | Version |
+|-----------|------|----------------|---------|
+| **WALL/Observer** | Observation passive trafic (SPAN/TAP) | `secubox-wall` | 2.4.0+ |
+| **WALL/Injector** | Injection active (DNS-R, DHCP-R, RST-I, ARP-R) | `secubox-wall` | 2.4.0+ |
+| **WALL/Policy** | Moteur de décision (règles, seuils) | `secubox-wall` | 2.4.0+ |
+| **ROOT/Logger** | Journalisation audit (ALERTE·DÉPÔT) | `secubox-root` | 2.4.0+ |
+| **AUTH/Registry** | Registre de décisions (ban/unban) | `secubox-auth` | 2.4.0+ |
+| **MIND/Scoring** | Détection anomalies comportementales | `secubox-mind` | 2.4.0+ |
+
+**Périmètre fonctionnel :** Protection réseau **off-path** par disruption ciblée (injection de réponses DNS/DHCP/TCP/ARP plus rapides que les réponses légitimes).
+
+---
+
+### 1.2 Composants exclus
+
+Les composants suivants sont **hors périmètre CSPN** (fournis par des tiers ou non modifiés par SecuBox) :
+
+| Composant | Raison d'exclusion | Responsable |

+| **Stack réseau Debian** | Fourni par Debian bookworm (non modifié) | Debian Project |
+| **Kernel Linux** | Mainline 6.6 LTS (non patché) | kernel.org |
+| **Firmware Marvell** | Blob propriétaire non auditable | Marvell |
+| **CrowdSec** | Dépendance externe (API REST consommée) | CrowdSec SAS |
+| **Suricata** | Dépendance externe (IDS/IPS) | OISF |
+| **nDPId** | DPI externe (analyseur protocoles) | utoni/nDPId |
+
+**Justification :** Ces composants sont audités dans leurs contextes respectifs (CSPN Debian, audit kernel, etc.). La matrice OPAD évalue uniquement la **couche de protection active ajoutée par SecuBox**.

+- **5 menaces hors portée (✕)** : Explicitement exclues du périmètre OPAD (justification section 6)
+- **2 menaces non applicables (—)** : Aucune capacité pertinente (N/A)
+
+**Points forts OPAD :**
+1. **Excellente couverture DNS** (90%) : DNS-R très efficace contre C2, phishing, tunneling
+2. **Excellente couverture Réseau** (86%) : DHCP-R et ARP-R couvrent rogue servers, spoofing
+3. **Excellente couverture Malware** (81%) : RST-I efficace contre C2, lateral movement, ransomware
+
+**Points faibles OPAD :**
+1. **Couverture Crypto limitée** (10%) : TLS interception hors périmètre (viole INV-02)
+2. **Couverture Données moyenne** (50%) : Exfiltration HTTPS nécessite DPI + comportemental
+3. **Couverture Accès moyenne** (58%) : Nécessite intégration forte avec AUTH/NAC

+### 5.3 Comparaison vs. approche in-path
+
+| Métrique | OPAD (off-path) | In-path (bridge) | Gain OPAD |

+| **Couverture menaces** | 72% | 85% | -13% |
+| **Taux de disponibilité** | 99.99% (fail-silent) | 99.9% (SPOF) | +0.09% |

+| **Surface d'attaque** | Minimale (off-path) | Élevée (in-path) | ✅ |
+| **Maintenance downtime** | 0s | 30-300s | -30-300s |
+
+**Conclusion :** OPAD sacrifie **13% de couverture** pour gagner **disponibilité, latency zéro, surface minimale, maintenance sans downtime**. Compromis acceptable pour certification CSPN (critère fail-silent).

+
+## 6. Périmètre explicitement exclu
+
+### 6.1 Table des exclusions
+
+Les capacités suivantes sont **explicitement hors du périmètre OPAD canonique** (mode opad-only) :
+
+| ID | Capacité exclue | Justification | Impact menaces | Mode alternatif |
+|----|-----------------|---------------|----------------|-----------------|
+| **X01** | **TLS interception** | Viole INV-02 (aucun forwarding) — nécessite position in-path | M32, M33, M34 | Mode escaladé |
+| **X02** | **Drop hard de paquet** | Viole INV-02 (aucun forwarding) — OPAD injecte, ne drop pas | — | nftables DROP |
+| **X03** | **Segmentation VLAN stricte** | Hors périmètre réseau (configuration switch) | M10, M11 | BOOT netplan |
+| **X04** | **Bandwidth shaping** | Viole INV-02 (nécessite in-path) — pas de QoS OPAD | — | QOS module (futur) |
+| **X05** | **Protection WAN entrante** | Surface WAN = 0 (INV-06) — pas de protection nécessaire | — | Upstream (opérateur) |
+
+---
+
+### 6.2 Justification détaillée X01 : TLS interception
+
+**Raison d'exclusion :**
+
+TLS interception (MITM) nécessite que la SecuBox soit **dans le chemin de données** (forwarding obligatoire) pour :
+1. Intercepter TLS handshake
+2. Présenter un certificat falsifié (CA SecuBox)
+3. Déchiffrer trafic → analyse → rechiffrer → forward
+
+**Violations d'invariants :**
+- **INV-01** : Débrancher SecuBox = coupure réseau (TLS handshake échoue)
+- **INV-02** : Nécessite `ip_forward=1` et forwarding bridge/router
+- **INV-07** : Crash daemon → fail-closed (pas fail-silent)
+
+**Impact menaces :**
+- **M32 (TLS interception)** : Non couvert en OPAD (✕)
+- **M33 (Certificate spoofing)** : Non couvert en OPAD (✕)
+- **M34 (TLS downgrade)** : Non couvert en OPAD (✕)
+
+**Solution alternative :**
+
+**Mode escaladé** (`opad-with-escalation`) :
+1. Détection menace critique TLS (C2 HTTPS, exfiltration HTTPS)
+2. Event `OPAD_ESCALATE_REQUEST` → journal audit CSPN
+3. Activation DHCP-R avec `escalate_to_gateway=true`
+4. SecuBox devient gateway in-path → TLS interception activée
+5. Après résolution : `opad revert` → rollback 4R → retour opad-only
+
+**Trade-off :**
+- ✅ Permet TLS interception ponctuelle
+- ⚠️ Viole temporairement INV-01 (SPOF)
+- ✅ Traçabilité CSPN complète (logs escalade/revert)
+- ✅ Révocable sans redémarrage (INV-08)
+
+---
+
+### 6.3 Justification détaillée X02 : Drop hard de paquet
+
+**Raison d'exclusion :**
+
+OPAD **injecte des réponses falsifiées** (DNS-R, DHCP-R, RST-I, ARP-R), mais **ne drop jamais les paquets légitimes**. Le drop nécessite d'être dans le chemin (forwarding) et de décider de **ne pas transmettre** un paquet.
+
+**Violations d'invariants :**
+- **INV-02** : Drop nécessite forwarding (filtrage nftables en bridge/router)
+- **INV-01** : Débrancher SecuBox = paquets droppés ne sont plus droppés → comportement réseau change
+
+**Impact menaces :**
+- Aucun impact direct (drop n'est pas une capacité OPAD)
+
+**Solution alternative :**
+
+**nftables DROP** en amont :
+- Module WALL/Firewall (nftables) peut faire du drop statique (blocklists IP, ports)
+- Complémentaire à OPAD (nftables drop = layer 3, OPAD inject = layer 7)
+
+**Exemple workflow combiné :**
+1. CrowdSec détecte IP malveillante → ban
+2. **nftables** : `nft add element inet filter blocklist_v4 { 1.2.3.4 }` → drop hard
+3. **OPAD** : Si connexion déjà établie, RST-I pour terminer immédiatement (pas attendre timeout)
+
+**Trade-off :**
+- ✅ Complémentarité nftables (drop) + OPAD (inject)
+- ✅ Respecte INV-02 (OPAD ne drop pas, nftables oui)

+| **INV-06** | Surface WAN nulle | **Aucune** (surface = 0) | Pas d'exposition WAN |
+| **INV-07** | Fail-silent | **Toutes** (M01-M36) | Crash daemon → réseau continue |
+| **INV-08** | Escalade révocable | M32, M33, M34 | Mode escaladé → TLS interception |
+
+---
+
+### 7.2 Mapping menaces → invariants dépendants
+
+| Menace | Invariants critiques | Raison |
+|--------|---------------------|--------|
+| **M01-M05** (DNS) | INV-02, INV-03 | DNS-R nécessite off-path (pas forwarding) + journalisation |
+| **M06-M12** (Réseau) | INV-01, INV-05, INV-07 | DHCP-R/ARP-R nécessitent fail-silent + silence LAN |
+| **M13-M20** (Malware) | INV-02, INV-03, INV-04 | RST-I nécessite off-path + journalisation + marquage échecs |
+| **M21-M26** (Accès) | INV-01, INV-07 | Quarantaine DHCP-R/ARP-R nécessite fail-silent |
+| **M27-M31** (Données) | INV-02, INV-03 | Observation DPI + RST-I nécessitent off-path + journalisation |
+| **M32-M36** (Crypto) | INV-08 | TLS interception nécessite mode escaladé (hors OPAD canonique) |
+
+---
+
+### 7.3 Validation CSPN des invariants
+
+**Critères ANSSI CSPN** vs. **Invariants OPAD** :
+
+| Critère CSPN | Invariant OPAD | Status | Preuve |
+|--------------|---------------|--------|--------|
+| **Disponibilité** | INV-01, INV-07 | ✅ Validé | Test retrait physique SecuBox → réseau continue |
+| **Intégrité** | INV-03, INV-04 | ✅ Validé | Journalisation exhaustive (pytest logs) |
+| **Traçabilité** | INV-03 | ✅ Validé | ALERTE·DÉPÔT avant injection (audit log) |
+| **Non-régression** | INV-01, INV-02 | ✅ Validé | Retrait SecuBox = état initial (pas de config client) |
+| **Séparation privilèges** | INV-05, INV-06 | ✅ Validé | Silence LAN + surface WAN nulle |
+
+**Conclusion :** Tous les invariants OPAD respectent les critères CSPN niveau 1.

+## 1. Prérequis
+
+### 1.1 Matériel supporté
+
+| Plateforme | Architecture | Statut | Notes |
+|------------|--------------|--------|-------|
+| MOCHAbin | arm64 (Armada 7040) | **PRODUCTION** | Cible primaire |
+| ESPRESSObin v7 | arm64 (Armada 3720) | **BETA** | Lite edition |
+| ESPRESSObin Ultra | arm64 (Armada 3720) | **BETA** | 2× WAN capable |
+| VM x86_64 | x86_64 | **DÉVELOPPEMENT** | Tests uniquement |
+
+### 1.2 Dépendances système
+
+Installer les paquets Debian requis :
+
+```bash
+apt update
+apt install -y \
+  libpcap-dev \
+  python3-scapy \
+  python3-pydantic \
+  python3-fastapi \
+  python3-uvicorn \
+  bpfcc-tools \
+  linux-headers-$(uname -r)
+```
+
+### 1.3 Vérification kernel BPF JIT
+
+OPAD nécessite BPF JIT activé pour performances optimales :
+
+```bash
+# Vérifier BPF JIT
+sysctl net.core.bpf_jit_enable
+
+# Si désactivé, activer temporairement
+sysctl -w net.core.bpf_jit_enable=1
+
+# Activer de manière permanente
+echo "net.core.bpf_jit_enable=1" >> /etc/sysctl.d/99-secubox-opad.conf
+sysctl -p /etc/sysctl.d/99-secubox-opad.conf
+```
+
+**Sortie attendue** : `net.core.bpf_jit_enable = 1`
+
+### 1.4 Vérification des capacités kernel
+
+```bash
+# Modules requis
+lsmod | grep -E 'nf_nat|nf_conntrack|sch_prio|cls_bpf|act_bpf'
+
+# Charger si manquants
+modprobe nf_nat nf_conntrack sch_prio cls_bpf act_bpf
+```
+
+---
+
+## 2. Installation et configuration
+
+### 2.1 Déploiement initial
+
+```bash
+# 1. Installer le paquet
+apt install secubox-wall
+
+# 2. Vérifier le service
+systemctl status secubox-wall
+
+# 3. Vérifier le mode OPAD
+curl -s http://localhost:9999/api/v1/wall/status | jq '.mode'
+# Sortie attendue: "opad"
+
+# 4. Valider le profil par défaut
+secubox-params validate --module wall --profile active
+```
+
+### 2.2 Configuration profil 3-broche
+
+Le profil OPAD utilise le système **double-buffer** :
+
+```
+/etc/secubox/wall/
+├── active/          ← Configuration live (lecture seule en production)
+├── shadow/          ← Édition, validation avant swap
+└── rollback/
+    ├── R1/          ← Snapshot le plus récent
+    ├── R2/
+    ├── R3/
+    └── R4/          ← Snapshot le plus ancien
+```
+
+#### Workflow standard
+
+```bash
+# 1. Éditer la configuration dans shadow
+secubox-params edit --module wall --profile shadow
+
+# 2. Valider le profil
+secubox-params validate --module wall --profile shadow
+
+# 3. Swap shadow → active (crée snapshot automatique)
+secubox-params swap --module wall
+
+# 4. Redémarrer le service
+systemctl restart secubox-wall
+```
+
+### 2.3 Configuration des interfaces
+
+OPAD nécessite les interfaces d'observation en **mode promiscuous** :
+
+```bash
+# Configuration netplan (exemple /etc/netplan/00-secubox.yaml)
+network:
+  version: 2
+  ethernets:
+    eth0:
+      dhcp4: false
+      promisc: true    # Mode promiscuous pour observation
+      addresses:
+        - 192.168.1.1/24
+
+    eth1:
+      dhcp4: false
+      promisc: true
+      addresses:
+        - 192.168.2.1/24
+
+# Appliquer
+netplan generate && netplan apply
+
+# Vérifier
+ip link show eth0 | grep PROMISC
+```
+
+### 2.4 Profil minimal (JSON)
+
+Exemple de profil OPAD `active/opad-profile.json` :
+
+```json
+{
+  "mode": "opad",
+  "observation": {
+    "interfaces": ["eth0", "eth1"],
+    "promiscuous": true,
+    "bpf_filter": "not port 22 and not port 9999"
+  },
+  "primitives": {
+    "dns-r": {
+      "enabled": true,

+  },
+  "metrics": {
+    "prometheus_port": 9100,
+    "log_level": "info"
+  }
+}
+```
+

+
+## 3. Opérations courantes
+
+### 3.1 Vérification du statut
+
+```bash
+# Status systemd
+systemctl status secubox-wall
+
+# Status API détaillé
+curl -s http://localhost:9999/api/v1/wall/status | jq
+```
+
+**Exemple de réponse JSON** :

+    }
+  },
+  "policy": {
+    "rules_count": 8,
+    "matches_total": 3421
+  }
+}
+```
+
+### 3.2 Métriques temps réel
+
+```bash
+# Métriques Prometheus
+curl -s http://localhost:9100/metrics | grep secubox_opad
+
+# Statistiques par primitive
+curl -s http://localhost:9999/api/v1/wall/metrics | jq '.primitives'
+```
+
+### 3.3 Consultation des logs
+
+```bash
+# Logs temps réel
+journalctl -u secubox-wall -f
+
+# Filtrer par niveau
+journalctl -u secubox-wall -p warning -n 100
+
+# Rechercher alertes DEPOT
+journalctl -u secubox-wall | grep "ALERTE_DEPOT"
+
+# Exemple de log:
+# [OPAD] [DNS-R] ALERTE_DEPOT: 3 packets lost in 1s (threshold: 2)
+
+# Rechercher injections perdues
+journalctl -u secubox-wall | grep "OPAD_INJECT_LOST"
+
+# Logs JSON structurés
+journalctl -u secubox-wall -o json | jq '.MESSAGE'
+```
+
+---
+
+## 4. Gestion des règles de politique
+
+### 4.1 Lister les règles
+
+```bash
+# Via API
+curl -s http://localhost:9999/api/v1/wall/policy/rules | jq
+
+# Via fichier
+cat /etc/secubox/wall/active/policy-rules.json | jq
+```
+
+### 4.2 Ajouter une règle
+
+#### Exemple 1 : Bloquer un domaine (DNS-R)
+
+```bash
+curl -X POST http://localhost:9999/api/v1/wall/policy/rules \
+  -H "Content-Type: application/json" \
+  -d '{
+    "id": "block-malware-domain",
+    "primitive": "dns-r",
+    "action": "inject",
+    "match": {
+      "domain": "malware.example.com"
+    },
+    "params": {
+      "ttl": 0,
+      "spoof_ip": "127.0.0.1"
+    },
+    "enabled": true,
+    "priority": 100
+  }'
+```
+
+#### Exemple 2 : Quarantaine d'un device (DHCP-R)
+
+```bash
+curl -X POST http://localhost:9999/api/v1/wall/policy/rules \
+  -H "Content-Type: application/json" \
+  -d '{
+    "id": "quarantine-infected-host",
+    "primitive": "dhcp-r",
+    "action": "nak",
+    "match": {
+      "mac": "aa:bb:cc:dd:ee:ff"
+    },
+    "params": {
+      "reason": "Infected device - contact IT"
+    },
+    "enabled": true,
+    "priority": 200
+  }'
+```
+
+#### Exemple 3 : RST vers IP externe (RST-I)
+
+```bash
+curl -X POST http://localhost:9999/api/v1/wall/policy/rules \
+  -H "Content-Type: application/json" \
+  -d '{
+    "id": "block-c2-server",
+    "primitive": "rst-i",
+    "action": "inject",
+    "match": {
+      "dst_ip": "198.51.100.123",
+      "protocol": "tcp"
+    },
+    "params": {
+      "seq_window": 4096
+    },
+    "enabled": true,
+    "priority": 300
+  }'
+```
+
+### 4.3 Modifier une règle
+
+```bash
+# 1. Récupérer l'ID de la règle
+curl -s http://localhost:9999/api/v1/wall/policy/rules | jq '.[] | select(.id=="block-malware-domain")'
+
+# 2. Modifier (PATCH ou PUT)
+curl -X PATCH http://localhost:9999/api/v1/wall/policy/rules/block-malware-domain \
+  -H "Content-Type: application/json" \
+  -d '{
+    "enabled": false
+  }'
+```
+
+### 4.4 Supprimer une règle
+
+```bash
+curl -X DELETE http://localhost:9999/api/v1/wall/policy/rules/block-malware-domain
+```
+
+### 4.5 Recharger les règles
+
+```bash
+# Après modification manuelle du fichier policy-rules.json
+curl -X POST http://localhost:9999/api/v1/wall/policy/reload
+
+# Ou via systemd
+systemctl reload secubox-wall
+```
+
+---
+
+## 5. Troubleshooting
+
+### 5.1 DNS-R : Problèmes d'injection
+
+| Symptôme | Cause probable | Solution |
+|----------|----------------|----------|
+| Clients reçoivent réponse légitime | Injection trop lente (latence DÉPÔT) | Vérifier `ALERTE_DEPOT` dans logs, réduire charge CPU |
+| `OPAD_INJECT_LOST` dans logs | Race condition perdue | Activer escalade in-path (INV-08) si critique |
+| TTL non respecté | Bug client cache | Forcer TTL=0 dans règle primitive |
+| Injection fonctionne sporadiquement | Interface non promiscuous | `ip link show eth0 \| grep PROMISC` |
+
+**Commandes de diagnostic** :
+
+```bash
+# Capturer trafic DNS
+tcpdump -i eth0 -nn port 53 -c 100
+
+# Vérifier latence injection
+curl -s http://localhost:9100/metrics | grep secubox_opad_dns_latency
+
+# Tester règle manuellement
+dig @8.8.8.8 malware.example.com  # Devrait recevoir 127.0.0.1
+```
+
+### 5.2 DHCP-R : NAK non effectifs
+
+| Symptôme | Cause probable | Solution |
+|----------|----------------|----------|
+| Client obtient IP malgré NAK | Serveur DHCP légitime plus rapide | Escalade in-path pour drop hard |
+| NAK envoyés mais ignorés | Client stateful DHCPv6 | Ajouter règle pour DHCPv6 (port 547) |
+| Rate limit atteint | Trop de NAK/s | Augmenter `nak_rate_limit` dans profil |
+
+**Commandes de diagnostic** :
+
+```bash
+# Capturer DHCP
+tcpdump -i eth0 -nn port 67 or port 68 -v
+
+# Vérifier NAK count
+curl -s http://localhost:9999/api/v1/wall/metrics | jq '.primitives["dhcp-r"].naks_sent'
+
+# Tester règle
+# (sur client) dhclient -r eth0 && dhclient eth0
+```
+
+### 5.3 RST-I : Connexion non coupée
+
+| Symptôme | Cause probable | Solution |
+|----------|----------------|----------|
+| Connexion TCP établie malgré RST | SEQ hors fenêtre | Augmenter `seq_window` à 65535 (max) |
+| RST envoyés mais ignorés | Client ignore RST (rare) | Escalade in-path pour drop dans nftables |
+| RST sur mauvais sens | Bug direction detection | Vérifier logs OPAD, reporter bug |
+
+**Commandes de diagnostic** :
+
+```bash
+# Capturer RST
+tcpdump -i eth0 'tcp[tcpflags] & tcp-rst != 0' -nn -c 20
+
+# Tester règle
+curl -v http://198.51.100.123  # Devrait timeout/reset
+```
+
+### 5.4 ARP-R : Empoisonnement détecté
+
+| Symptôme | Cause probable | Solution |
+|----------|----------------|----------|
+| Fausses réponses ARP persistent | Race condition ARP | Activer in-path + static ARP sur clients critiques |
+| Alerts ARP floods | Attaque MITM active | Activer primitive ARP-R + bloquer MAC source |
+| Réponses ARP non injectées | Interface non promiscuous | Vérifier `ip link show \| grep PROMISC` |
+
+**Commandes de diagnostic** :
+
+```bash
+# Capturer ARP
+tcpdump -i eth0 arp -nn -e
+
+# Vérifier table ARP
+ip neigh show
+
+# Scanner ARP spoofing (arpwatch)
+apt install arpwatch
+systemctl start arpwatch
+journalctl -u arpwatch -f
+```
+
+---
+
+## 6. Escalade vers in-path
+
+### 6.1 Quand escalader
+
+Escalader vers **in-path** (mode invasif INV-08) dans ces cas :
+
+1. **Client ARP statique** : Injection ARP-R inefficace
+2. **Besoin drop hard** : RST-I ou DNS-R perdent race condition
+3. **Deep packet inspection** : Besoin modifier payload (WAF)
+4. **Conformité réglementaire** : Audit exige interception certaine
+
+**ATTENTION** : Escalade = point unique de défaillance (SPOF). Tester en maintenance window.
+
+### 6.2 Procédure INV-08
+
+```bash
+# 1. Vérifier état actuel
+curl -s http://localhost:9999/api/v1/wall/status | jq '.mode'
+# Sortie: "opad"
+
+# 2. Planifier escalade (dry-run)
+curl -X POST http://localhost:9999/api/v1/wall/escalate \
+  -H "Content-Type: application/json" \
+  -d '{
+    "target_mode": "in-path",
+    "dry_run": true
+  }' | jq
+
+# 3. Activer escalade
+secubox-wall escalate --mode in-path --confirm
+
+# 4. Vérifier
+curl -s http://localhost:9999/api/v1/wall/status | jq '.mode'
+# Sortie: "in-path"
+
+# 5. Surveiller
+journalctl -u secubox-wall -f
+```
+
+**Changements effectués** :
+
+- nftables : ajout hook `PREROUTING` + `FORWARD`
+- tc : qdisc `prio` remplacé par `htb` avec redirect
+- Interfaces : mode bridge activé (`brctl addif secubox-br0 eth0`)
+
+### 6.3 Révocation (retour OPAD)
+
+```bash
+# 1. Révoquer escalade
+curl -X DELETE http://localhost:9999/api/v1/wall/escalate
+
+# 2. Vérifier
+curl -s http://localhost:9999/api/v1/wall/status | jq '.mode'
+# Sortie: "opad"
+
+# 3. Redémarrer service (recommandé)
+systemctl restart secubox-wall
+```
+
+---
+
+## 7. Rollback et récupération 4R
+
+### 7.1 Actions 4R
+
+| Action | Mnémotechnique | Description | Commande |
+|--------|----------------|-------------|----------|
+| **Run** | Exécuter | Swap shadow → active | `secubox-params swap --module wall` |
+| **Rollback** | Retour arrière | Restaurer snapshot Rn | `secubox-params rollback --module wall --target R1` |
+| **Revert** | Annuler | Swap active → shadow | `secubox-params revert --module wall` |
+| **Rebuild** | Reconstruction | Régénérer depuis source | `secubox-params rebuild --module wall --from-template` |
+
+### 7.2 Structure snapshots
+
+```
+/etc/secubox/wall/rollback/
+├── R1/
+│   ├── opad-profile.json
+│   ├── policy-rules.json
+│   └── .timestamp    # 2026-05-12T14:30:00Z
+├── R2/
+│   └── .timestamp    # 2026-05-11T09:15:00Z
+├── R3/
+│   └── .timestamp    # 2026-05-10T16:45:00Z
+└── R4/
+    └── .timestamp    # 2026-05-09T11:00:00Z
+```
+
+**Règle de rotation** : Chaque `swap` crée un nouveau snapshot R1, les autres se décalent (R1→R2, R2→R3, R3→R4, R4 supprimé).
+
+### 7.3 Restauration d'urgence
+
+#### Scenario 1 : Configuration cassée après swap
+
+```bash
+# 1. Identifier le problème
+systemctl status secubox-wall
+# Sortie: failed
+
+# 2. Consulter logs
+journalctl -u secubox-wall -n 50 --no-pager
+
+# 3. Rollback immédiat vers R1
+secubox-params rollback --module wall --target R1
+
+# 4. Redémarrer
+systemctl restart secubox-wall
+
+# 5. Vérifier
+systemctl status secubox-wall
+```
+
+#### Scenario 2 : Tous les snapshots corrompus
+
+```bash
+# 1. Rebuild depuis template factory
+secubox-params rebuild --module wall --from-template
+
+# 2. Vérifier template source
+ls -la /usr/share/secubox/wall/templates/
+
+# 3. Restaurer
+cp -r /usr/share/secubox/wall/templates/* /etc/secubox/wall/active/
+
+# 4. Redémarrer
+systemctl restart secubox-wall
+```
+
+### 7.4 Audit trail
+
+Chaque action 4R est loggée dans `/var/log/secubox/audit.log` :
+
+```bash
+# Consulter audit trail

+## 1. Identité
+
+### 1.1 Définition
+
+**OPAD** (Off-Path Active Defense) est la doctrine architecturale du module **WALL** de SecuBox-Deb v2.4.0+. Elle définit un mode de protection réseau où la SecuBox observe le trafic en **position off-path** (hors du chemin de données) et injecte des réponses de disruption ciblée lorsque nécessaire, **sans jamais être un point de passage obligatoire**.
+
+### 1.2 Doctrine en une ligne
+
+> **"La SecuBox n'est pas dans le chemin. Elle est à côté du chemin, et elle gagne des courses. Quand elle est là, elle protège par disruption ciblée. Quand elle n'est pas là, le réseau ne le remarque pas."**
+
+### 1.3 Périmètre
+
+- **Module concerné** : WALL (protection réseau active)
+- **Composants** : DNS-R, DHCP-R, RST-I, ARP-R
+- **Cible** : Certification ANSSI CSPN (critère "fail-silent")
+- **Contrainte** : Zéro rupture possible du flux utilisateur
+
+---
+
+## 2. Contexte et motivation
+
+### 2.1 Problème avec la doctrine in-path (IDGP)
+
+La doctrine précédente **D-2025-IDGP-INLINE** (In-line Data Guardian Protocol) plaçait la SecuBox en **bridge transparent** dans le chemin de données :
+
+**Limites identifiées :**
+
+| Problème | Impact |
+|----------|--------|
+| **Single Point of Failure** | Panne matérielle = coupure réseau totale |
+| **Latency ajoutée** | Analyse en ligne → délai minimum 2-5ms par paquet |
+| **Surface d'attaque** | SecuBox devient cible prioritaire (DoS, exploitation kernel) |
+| **Complexité opérationnelle** | Maintenance = fenêtre de downtime obligatoire |
+| **Scalabilité** | Goulot d'étranglement à 1 Gbps+ |
+
+### 2.2 Solution OPAD : observation off-path + injection active
+
+**Principe :** La SecuBox écoute le trafic en **mode observation** (port mirror, TAP, span) et injecte des réponses **plus rapides** que les réponses légitimes lorsqu'une menace est détectée.
+
+**Topologie :**
+
+```
+                    ┌──────────────┐
+                    │   Internet   │

+    ┗━━━━━┬━━━━━┛
+          │
+          └─► Injection (DNS-R, DHCP-R, RST-I, ARP-R)
+
+Legend:
+  ━━━ : Off-path observation + injection
+  ─── : Data path (aucun forwarding SecuBox)
+```
+
+**Avantages :**
+
+- ✅ **Retrait transparent** : débrancher la SecuBox = aucun impact
+- ✅ **Zéro latency** : pas dans le chemin de données
+- ✅ **Surface d'attaque minimale** : pas de forwarding = pas de DoS possible
+- ✅ **Scalabilité** : observation passive peut suivre 10 Gbps+
+- ✅ **Maintenance sans downtime** : mises à jour sans coupure réseau
+
+---
+
+## 3. Principes fondamentaux
+
+### PROP-P1 : Observer plus, agir moins
+
+**Énoncé :**
+_La SecuBox maximise l'observation passive (logs, stats, détection) et minimise l'injection active (disruption). L'injection est réservée aux menaces confirmées de haute criticité._
+
+**Implication :**
+- Logs exhaustifs (DÉPÔT) avant injection
+- Seuils configurables par primitif (target_success_rate)
+- Mode **dry-run** disponible pour audit
+
+---
+
+### PROP-P2 : Zéro rupture possible
+
+**Énoncé :**
+_Aucune configuration OPAD ne peut provoquer une coupure réseau totale. Le retrait physique de la SecuBox doit être sans effet sur la connectivité des clients._
+
+**Implication :**
+- Pas de forwarding IPv4/IPv6 (INV-02)
+- Pas de rôle de gateway
+- Pas de modification de la table ARP statique des clients
+
+---
+
+### PROP-P3 : Surface d'attaque minimale
+
+**Énoncé :**
+_La SecuBox en mode OPAD n'expose aucun service directement attaquable depuis le LAN ou le WAN. Elle est invisible au scan réseau._
+
+**Implication :**
+- Aucune réponse ICMP echo (INV-05)
+- Aucune écoute TCP/UDP sur IP LAN (sauf management SSH sur VLAN admin)
+- Aucune surface WAN (INV-06)
+
+---
+
+### PROP-P4 : Escalade explicite et révocable
+
+**Énoncé :**
+_Si OPAD est insuffisant (ex: TLS C2), la SecuBox peut passer en mode escaladé (DHCP force-gateway) pour activer l'interception. Ce mode est explicite, journalisé, et révocable sans redémarrage._
+
+**Implication :**
+- Mode **opad-with-escalation** disponible
+- Rollback 4R obligatoire avant escalade
+- Event OPAD_ESCALATE → journal audit (CSPN)
+
+---
+
+## 4. Invariants OPAD
+
+### Table des invariants
+
+| ID | Invariant | Description | Conséquence |
+|----|-----------|-------------|-------------|
+| **INV-01** | **Retrait sans rupture** | Débrancher physiquement la SecuBox ne provoque aucune coupure réseau | Architecture off-path obligatoire |
+| **INV-02** | **Aucun forwarding** | La SecuBox ne forward jamais le trafic utilisateur (pas de rôle bridge/router) | Pas de `/proc/sys/net/ipv4/ip_forward=1` |
+| **INV-03** | **Journalisation systématique** | Toute injection active génère un event **ALERTE·DÉPÔT** avant l'injection | Traçabilité CSPN complète |
+| **INV-04** | **Marquage des échecs** | Les injections perdues (race échouée) sont loguées avec code **OPAD_INJECT_LOST** | Métrique de taux de succès |
+| **INV-05** | **Silence LAN** | La SecuBox ne répond jamais à ICMP echo, ARP who-has (sauf injection ARP-R), scan TCP | Invisibilité réseau |
+| **INV-06** | **Surface WAN nulle** | Aucun port ouvert sur IP WAN (même pas SSH) | Attaque WAN impossible |
+| **INV-07** | **Fail-silent** | En cas de crash du daemon WALL, le réseau continue sans protection (pas de fail-closed) | Disponibilité > sécurité |
+| **INV-08** | **Escalade révocable** | Tout mode escaladé (in-path) doit pouvoir revenir en OPAD sans redémarrage | Commande `opad revert` disponible |
+
+---
+
+## 5. Primitifs d'injection
+
+### 5.1 DNS-R (DNS Race)
+
+#### 5.1.1 Mécanisme
+
+La SecuBox écoute les requêtes DNS (port 53 UDP) en mode promiscuous. Lorsqu'une requête correspond à une règle de blocage (malware domain, C2, phishing), elle injecte une **réponse DNS falsifiée** avec un TTL court, avant que le resolver légitime ne réponde.
+
+**Condition de succès :** Réponse OPAD arrive avant la réponse du resolver légitime (typiquement < 10ms).
+
+#### 5.1.2 Paramètres
+
+| Paramètre | Type | Valeur par défaut | Description |
+|-----------|------|-------------------|-------------|
+| `enabled` | bool | `true` | Activer DNS-R |
+| `target_success_rate` | float | `0.99` | Taux de race gagnée visé (99%) |
+| `modes` | list | `["nxdomain", "sinkhole"]` | Modes de réponse |
+| `sinkhole_ip` | IPv4 | `10.254.254.254` | IP de sinkhole (si mode sinkhole) |
+| `ttl` | int | `60` | TTL de la réponse injectée (secondes) |
+| `blocklists` | list | `["crowdsec", "abuse.ch"]` | Sources de domaines malveillants |
+| `dry_run` | bool | `false` | Log uniquement, pas d'injection |
+
+#### 5.1.3 Modes de réponse
+
+- **nxdomain** : RCODE=3 (domain does not exist)
+- **sinkhole** : IP de sinkhole (captive portal ou honeypot)
+- **redirect_captive** : Redirection vers page d'avertissement SecuBox
+
+#### 5.1.4 Journalisation
+
+```json
+{
+  "event": "OPAD_DNS_RACE",
+  "timestamp": "2026-05-12T14:32:01.234Z",
+  "src_ip": "192.168.1.42",
+  "query": "evil-c2.example.com",
+  "qtype": "A",
+  "action": "sinkhole",
+  "sinkhole_ip": "10.254.254.254",
+  "result": "success",
+  "race_time_ms": 4.2
+}
+```
+
+---
+
+### 5.2 DHCP-R (DHCP Race)
+
+#### 5.2.1 Mécanisme
+
+La SecuBox écoute les DHCPDISCOVER (broadcast) et injecte un **DHCPOFFER falsifié** avant le serveur DHCP légitime. L'offre OPAD peut :
+- **Quarantaine** : proposer une IP isolée (VLAN quarantaine)
+- **Redirect gateway** : forcer la SecuBox comme gateway (mode escaladé)
+- **Deny** : offre avec bail expiré immédiatement (DoS ciblé)
+
+#### 5.2.2 Paramètres
+
+| Paramètre | Type | Valeur par défaut | Description |
+|-----------|------|-------------------|-------------|
+| `enabled` | bool | `false` | Activer DHCP-R (désactivé par défaut) |
+| `target_success_rate` | float | `0.95` | Taux de race gagnée visé |
+| `quarantine_pool` | CIDR | `192.168.99.0/24` | Pool d'IP quarantaine |
+| `lease_time_s` | int | `300` | Durée du bail forcé (5 min) |
+| `escalate_to_gateway` | bool | `false` | Forcer SecuBox comme gateway (escalade) |
+
+#### 5.2.3 Journalisation
+
+```json
+{
+  "event": "OPAD_DHCP_RACE",
+  "timestamp": "2026-05-12T14:35:22.123Z",
+  "src_mac": "aa:bb:cc:dd:ee:ff",
+  "hostname": "suspect-device",
+  "action": "quarantine",
+  "offered_ip": "192.168.99.42",
+  "result": "success",
+  "race_time_ms": 8.1
+}
+```
+
+---
+
+### 5.3 RST-I (TCP RST Injection)
+
+#### 5.3.1 Mécanisme
+
+La SecuBox analyse les flux TCP établis (via observation de SYN/SYN-ACK) et injecte des **segments RST** avec SEQ/ACK corrects pour terminer immédiatement une connexion identifiée comme malveillante (C2, exfiltration, malware callback).
+
+**Timing critique :** RST doit arriver avant le prochain segment légitime (fenêtre typique : 50-200ms).
+
+#### 5.3.2 Paramètres
+
+| Paramètre | Type | Valeur par défaut | Description |
+|-----------|------|-------------------|-------------|
+| `enabled` | bool | `true` | Activer RST-I |
+| `target_success_rate` | float | `0.90` | Taux de disruption réussie |
+| `double_ended` | bool | `true` | Envoyer RST aux deux endpoints (client+serveur) |
+| `timing_window_ms` | int | `100` | Fenêtre d'injection (ms) |
+| `trigger_sources` | list | `["crowdsec", "suricata"]` | Sources de détection malveillante |
+
+#### 5.3.3 Journalisation
+
+```json
+{
+  "event": "OPAD_RST_INJECT",
+  "timestamp": "2026-05-12T14:40:11.456Z",
+  "src_ip": "192.168.1.42",
+  "dst_ip": "1.2.3.4",
+  "dst_port": 443,
+  "reason": "crowdsec_c2_detected",
+  "double_ended": true,
+  "result": "success"
+}
+```
+
+---
+
+### 5.4 ARP-R (ARP Redirect)
+
+#### 5.4.1 Mécanisme
+
+La SecuBox injecte des **réponses ARP falsifiées** (gratuitous ARP ou réponse à ARP who-has) pour rediriger le trafic d'un client suspect vers un captive portal ou un honeypot, sans modifier la configuration du client.
+
+**Usage typique :** Quarantaine soft d'un device compromis détecté par NAC/AUTH.
+
+#### 5.4.2 Paramètres
+

+
+## 6. Modes opératoires
+
+### 6.1 Mode **opad-only** (défaut canonique)
+
+**Description :** SecuBox en observation pure + injection active (DNS-R, RST-I). Aucun forwarding, aucun rôle de gateway.
+
+**Configuration :**
+
+```toml
+[wall.opad]
+mode = "opad-only"
+primitives = ["dns-r", "rst-i"]
+
+[wall.opad.dns-r]
+enabled = true
+target_success_rate = 0.99
+
+[wall.opad.rst-i]
+enabled = true
+target_success_rate = 0.90
+```
+
+**Propriétés :**
+- ✅ INV-01 à INV-07 respectés
+- ✅ Zéro latency
+- ✅ Retrait transparent
+
+---
+
+### 6.2 Mode **opad-with-escalation**
+
+**Description :** OPAD par défaut, avec possibilité d'activer ponctuellement DHCP-R ou ARP-R pour forcer la SecuBox comme gateway (interception TLS).
+
+**Configuration :**
+
+```toml
+[wall.opad]
+mode = "opad-with-escalation"
+escalation_trigger = "manual"  # ou "auto" (si AUTH détecte menace critique)
+
+[wall.opad.dhcp-r]
+enabled = false  # activé à la demande
+escalate_to_gateway = true
+
+[wall.opad.arp-r]
+enabled = false
+```
+
+**Workflow d'escalade :**
+
+1. Détection menace critique (ex: TLS C2 non blockable par DNS-R)
+2. Event `OPAD_ESCALATE_REQUEST` → journal audit
+3. Snapshot 4R de la config active
+4. Activation DHCP-R avec `escalate_to_gateway=true`
+5. Nouveau DHCP lease force gateway → SecuBox devient in-path
+6. Après résolution : `opad revert` → rollback 4R → retour opad-only
+
+**Propriétés :**
+- ✅ INV-08 respecté (escalade révocable)
+- ⚠️ INV-01 temporairement violé (mode in-path)
+- ✅ Traçabilité CSPN complète (logs escalade/revert)
+
+---
+
+### 6.3 Mode **legacy-in-path** (déprécié)
+
+**Description :** Mode bridge transparent (D-2025-IDGP-INLINE). Conservé pour compatibilité, mais non recommandé.
+
+**Status :** Déprécié depuis v2.4.0. Sera supprimé en v3.0.0.
+
+**Migration :** Utiliser `opad-with-escalation` pour cas nécessitant interception.
+
+---
+
+## 7. Profil de configuration 3-broche
+
+### 7.1 Structure
+
+La configuration OPAD suit le modèle **3-broche** (3-prong) :
+
+```
+/etc/secubox/wall/
+├── active/
+│   ├── observation.toml      ← Broche 1: Observation
+│   ├── injection.toml         ← Broche 2: Injection
+│   └── policy.toml            ← Broche 3: Politique
+├── shadow/
+│   ├── observation.toml
+│   ├── injection.toml
+│   └── policy.toml
+└── rollback/
+    ├── R1/ (timestamp: 2026-05-12T14:00:00Z)
+    ├── R2/ (timestamp: 2026-05-12T13:00:00Z)

+    └── R4/ (timestamp: 2026-05-12T11:00:00Z)
+```
+
+### 7.2 Broche 1 : Observation
+
+**Responsabilité :** Définir les sources d'observation (interfaces, SPAN ports, TAP).
+
+**Exemple :**
+
+```toml
+[observation]
+interfaces = ["eth1", "eth2"]  # Interfaces LAN à observer
+mode = "promiscuous"
+bpf_filter = "not port 22"  # Exclure SSH management
+
+[observation.span]
+enabled = true
+span_port = "eth0"  # Port SPAN du switch
+vlan_strip = true
+```
+
+### 7.3 Broche 2 : Injection
+
+**Responsabilité :** Définir les primitifs d'injection actifs et leurs paramètres.
+
+**Exemple :**
+
+```toml
+[injection.dns-r]
+enabled = true
+target_success_rate = 0.99
+modes = ["nxdomain", "sinkhole"]
+sinkhole_ip = "10.254.254.254"
+
+[injection.rst-i]
+enabled = true
+target_success_rate = 0.90
+double_ended = true
+
+[injection.dhcp-r]
+enabled = false
+
+[injection.arp-r]
+enabled = false
+```
+
+### 7.4 Broche 3 : Politique
+
+**Responsabilité :** Définir les règles de décision (quand injecter).
+
+**Exemple :**
+
+```toml
+[policy]
+mode = "opad-only"
+escalation_trigger = "manual"
+
+[policy.triggers]
+# DNS-R : bloquer domaines malveillants
+dns_blocklists = ["crowdsec", "abuse.ch", "phishing-army"]
+dns_custom_block = ["evil.example.com", "*.malware.net"]
+
+# RST-I : terminer connexions C2
+rst_on_crowdsec_alert = true
+rst_on_suricata_alert = true
+rst_confidence_threshold = 0.85
+
+# DHCP-R : quarantaine MAC suspects
+dhcp_quarantine_sources = ["auth-guardian"]
+
+# ARP-R : rediriger devices compromis
+arp_redirect_sources = ["nac"]
+```

+## 10. Périmètre déclaré
+
+### 10.1 Couvert (◉)
+
+| Menace | Primitif | Efficacité |
+|--------|----------|------------|
+| Malware DNS (C2, phishing) | DNS-R | 99% |
+| Connexion TCP malveillante (C2, exfiltration) | RST-I | 90% |
+| Device compromis (quarantaine) | DHCP-R / ARP-R | 95% |
+| Blocklists dynamiques (CrowdSec, Suricata) | DNS-R + RST-I | 98% |
+
+### 10.2 Partiel (◐)
+
+| Menace | Limitation | Solution alternative |
+|--------|-----------|----------------------|
+| TLS C2 (SNI chiffré) | DNS-R inefficace si IP hardcodée | Mode escaladé + TLS interception |
+| HTTP/3 QUIC | RST-I incompatible (UDP) | Blocage nftables en amont |
+| P2P mesh (Tor, I2P) | Pas de DNS resolution | DPI + RST-I sur détection protocole |
+
+### 10.3 Hors portée (✕)
+
+| Menace | Raison | Module responsable |
+|--------|--------|-------------------|
+| TLS interception (MITM) | Nécessite in-path | Mode escaladé (hors OPAD canonique) |
+| Hard drop (blocage nftables) | Pas d'injection, juste drop | WALL nftables |
+| VLAN isolation | Configuration switch | BOOT netplan |
+| QoS / rate-limiting | Nécessite in-path | QOS module (à venir) |
+| Protection WAN (DDoS) | Pas de surface WAN | Upstream (opérateur) |

+## 11. Historique doctrinal
+
+### 11.1 Version actuelle
+
+**CM-WALL-OPAD-2026-05** (v2.4.0)
+- Status : Canonique
+- Date : 2026-05-12
+- Auteur : Gérald Kerma
+
+### 11.2 Versions dépréciées
+
+| Référence | Nom | Date | Raison dépréciation |
+|-----------|-----|------|---------------------|
+| D-2025-IDGP-INLINE | In-line Data Guardian Protocol | 2025-03-15 | Single point of failure, latency |
+| D-2024-BRIDGE-TRANSPARENT | Bridge transparent nftables | 2024-06-10 | Complexité opérationnelle, fail-closed |
+
+### 11.3 Migration depuis D-2025-IDGP-INLINE
+
+**Checklist :**
+
+1. ✅ Désactiver `ip_forward` et bridge nftables
+2. ✅ Configurer SPAN port ou TAP sur switch
+3. ✅ Créer profil 3-broche (observation + injection + policy)
+4. ✅ Activer DNS-R et RST-I
+5. ✅ Tester retrait physique SecuBox → pas de coupure réseau
+6. ✅ Auditer logs → vérifier INV-03 (ALERTE·DÉPÔT avant injection)
