 #### Use HTTPS to communicate with the LAPI
 
-To communicate with the LAPI in HTTPS you need to either accept any certificates by setting the `crowdsecLapiTLSInsecureVerify` to true or add the CA used by the server certificate of Crowdsec using `crowdsecLapiTLSCertificateAuthority` or `crowdsecLapiTLSCertificateAuthorityFile`.
-Set the `crowdsecLapiScheme` to https.
+Set `crowdsecLapiScheme` to `https`. The plugin then validates Crowdsec's server certificate. Three options:
+
+- **Publicly trusted certificate** (e.g. Let's Encrypt behind a reverse proxy): leave `crowdsecLapiTLSCertificateAuthority` empty and `crowdsecLapiTLSInsecureVerify` `false`. The plugin falls back to the host's system trust store (the `traefik` image ships `ca-certificates`).
+- **Private/self-signed CA**: set `crowdsecLapiTLSCertificateAuthority` (or `…File`) to the PEM-encoded CA that signed Crowdsec's server cert.
+- **Skip verification entirely** (not recommended for production): set `crowdsecLapiTLSInsecureVerify` to `true`.
 
 Crowdsec must be listening in HTTPS for this to work.
 Please see the [tls-auth example](https://github.com/maxlerebourg/crowdsec-bouncer-traefik-plugin/blob/main/examples/tls-auth/README.md) or the official documentation: [docs.crowdsec.net/docs/local_api/tls_auth/](https://docs.crowdsec.net/docs/local_api/tls_auth/)
 
 #### Use HTTPS to communicate with the Appsec
 
-To communicate with the Appsec in HTTPS you need to either accept any certificates by setting the `crowdsecAppsecTLSInsecureVerify` to true or add the CA used by the server certificate of Crowdsec using `crowdsecAppsecTLSCertificateAuthority` or `crowdsecAppsecTLSCertificateAuthorityFile`.
-Set the `crowdsecAppsecScheme` to https.
+Set `crowdsecAppsecScheme` to `https`. Same three options as for the LAPI, prefixed `crowdsecAppsec…` instead of `crowdsecLapi…`: empty CA + secure verify falls back to the system trust store, a custom CA pins to your private PKI, and `crowdsecAppsecTLSInsecureVerify=true` skips verification altogether.
 
 Currently AppSec does not support mTLS authentication for the AppSec Component.

-# End-to-end test suite
-
-These tests spin up real Traefik + Crowdsec containers and exercise the
-plugin in the same conditions Traefik uses in production: loaded from a
-local path, no module download, no mocking.
-
-Each scenario lives in its own directory under `scenarios/` and owns:
-
-- `docker-compose.yml` — the stack to spin up
-- `run.sh` — orchestration + assertions
-- optional fixtures (`acquis.yaml`, `ban.html`, ...)
-
-## Running locally
-
-Prerequisites: `docker`, `docker compose`, `curl`, `bash`.
-
-Run a single scenario:
-
-```bash
-./tests/e2e/scenarios/stream-mode/run.sh
-# or
-make e2e_stream-mode
-```
-
-Run everything:
-
-```bash
-make e2e
-```
-
-Scenarios run **sequentially** on a single host: they share the canonical
-`crowdsec` container name (so `cscli` commands work uniformly) and the same
-`8000:80` port. Each scenario uses its own Docker Compose project
-(`-p e2e-<scenario>`) and tears its stack down on exit, so the next one
-starts clean. `make e2e` runs them one after another; Docker reuses the
-images pulled by the first scenario, so the Traefik / Crowdsec / whoami
-images are downloaded only once for the whole suite.
-
-## Writing a new scenario
-
-1. Copy `scenarios/stream-mode/` as a template.
-2. Rename `container_name`s (keep `crowdsec` for the LAPI container).
-3. Edit `run.sh` to express the behavior under test.
-4. Add the scenario name to `E2E_SCENARIOS` in the `Makefile`.
-
-## CI
-
-This Docker suite is **local-only** and intentionally not run in CI: it boots a
-real Crowdsec (and downloads the AppSec collections for that scenario), which is
-heavier and less deterministic than CI needs. CI instead runs a lighter
-binary + mock-LAPI suite that exercises the plugin without Docker or a real
-Crowdsec.
-
-Run this suite locally with `make e2e` (all scenarios) or
-`make e2e_<scenario>` (one scenario).

+# Binary e2e suite (Traefik binary + mock LAPI)
+
+This suite runs **Traefik as a downloaded binary** with the plugin loaded from
+the local source tree, and replaces Crowdsec with a small **HTTP mock**
+([`mocklapi/`](mocklapi/main.go), a stdlib-only Go command). No Docker, no real
+Crowdsec.
+
+It is what **CI runs** (`make e2e_mock`). A separate, local-only **Docker
+suite** (real Traefik + Crowdsec, under `tests/e2e/scenarios`) is kept for
+high-fidelity debugging against a real Crowdsec but is not exercised in CI; it
+ships in its own PR (#333).
+
+## Scope — what this suite tests
+
+These tests validate the **plugin's own behaviour**: the request flow through
+the Traefik middleware, the live / none / stream modes, caching, trusted-IP
+bypass, ban / captcha page rendering, and the AppSec request path (header
+forwarding + enforcing the engine's allow/block verdict).
+
+The mock stands in for Crowdsec, emulating the slice of the LAPI HTTP contract
+the plugin consumes — including a single, deterministic AppSec rule (block any
+URI containing `rpc2`, the probe from [`examples/appsec-enabled`](../../../examples/appsec-enabled)).
+It is not the real WAF engine, so this suite exercises the plugin's AppSec
+*wiring* rather than the detection accuracy of OWASP CRS / virtual patching —
+that lives upstream in Crowdsec.
+
+## What runs
+
+| Component | How |
+|-----------|-----|
+| Traefik   | Binary `v3.7.1`, downloaded into `.cache/` (reused across local runs; re-downloaded on fresh CI runners) |
+| Plugin    | Loaded via `experimental.localPlugins` from the repo root (symlinked into `plugins-local/`) |
+| LAPI      | `mocklapi` — a stdlib-only Go command (its own nested module), compiled and cached under `.cache/`, driven through `/admin` endpoints instead of `cscli`. Serves plain HTTP, or HTTPS when `--lapi-tls-cert/--lapi-tls-key` are passed (the `tls-system-ca` scenario) |
+| AppSec    | WAF stand-in built into the mock — blocks URIs containing `rpc2`, allows the rest |
+| Backend   | A plain HTTP responder built into the mock |
+
+Fixed ports (override with env vars if needed): Traefik `8000`, LAPI `8090`,
+backend `8091`, AppSec `8092`.
+
+## Running locally
+
+Prerequisites: `bash`, `curl`, `go`, `tar` (plus `openssl` for the
+`tls-system-ca` scenario, which mints a throwaway CA at runtime). On first use
+the Traefik binary is fetched and the mock is compiled into `.cache/`. That
+cache is reused across local runs; CI runs on fresh runners, so both are
+recreated on every CI run.
+
+The `tls-system-ca` scenario verifies that, with no custom CA configured, the
+bouncer falls back to the OS/system trust store for an HTTPS LAPI: it serves the
+mock over TLS and points the Traefik process's `SSL_CERT_FILE` at the test CA
+(trusted → 200) or an empty bundle (untrusted → 403, proving it still verifies).
+
+```bash
+# one scenario
+make e2e_mock_stream-mode
+# or directly
+./tests/e2e/mock/scenarios/stream-mode/run.sh
+
+# the whole suite
+make e2e_mock
+```
+
+## Layout
+
+```
+mock/
+  lib/
+    common.sh     # stack lifecycle, Traefik download, mock build, assertions, admin client
+    traefik.yml   # static Traefik config (shared by all scenarios)
+  mocklapi/
+    go.mod        # nested module — kept out of the plugin's build/lint/vendor
+    main.go       # mock LAPI + AppSec stand-in + backend
+  scenarios/
+    <name>/
+      dynamic.yml # Traefik dynamic config (router + bouncer middleware + backend)
+      run.sh      # assertions for the scenario
+      *.html      # optional fixtures (ban / captcha templates)
+```
+
+`dynamic.yml` uses placeholders (`@@APIKEY@@`, `@@LAPI_HOST@@`,
+`@@BACKEND_URL@@`, `@@SCENARIO_DIR@@`) that `common.sh` substitutes at runtime.
+
+## Adding a scenario
+
+1. Create `scenarios/<name>/dynamic.yml` and `run.sh` (copy `stream-mode/` as a
+   template).
+2. In `run.sh`, define a `body` function with the assertions and call
+   `run_scenario "<name>" "$HERE" body`.
+3. Drive decisions with `lapi_add_decision <ip> [type] [duration]` and
+   `lapi_delete_decision <ip>`.
+4. Add `<name>` to `E2E_MOCK_SCENARIOS` in the `Makefile`.
