+### Windows (use WSL for the Linux-only tests)
+
+The Rust adapter tests run natively on Windows through the cargo aliases
+(`cargo test-fastly` via Viceroy, `cargo test-axum`, `cargo test-cloudflare`),
+and CI runs these on both `ubuntu-latest` and `windows-latest`.
+
+The Docker-based integration suite (`scripts/integration-tests.sh`) and the
+Cloudflare worker build (`crates/trusted-server-adapter-cloudflare/build.sh`,
+which uses `worker-build` + `wrangler dev`) are Linux tools. On Windows run them
+inside WSL (Ubuntu) with Docker Desktop's WSL integration enabled. Provision the
+WSL distro with the same toolchain as `.tool-versions` (rustup + the
+`wasm32-wasip1` / `wasm32-unknown-unknown` targets, Node, Viceroy, wrangler), then
+run the scripts from a clone on the WSL native filesystem for fast builds.

 ## Coding Conventions
@@ -265,12 +285,34 @@ impl core::error::Error for MyError {}
 
 ## Other guidelines
 
+- Use US English spelling everywhere: code, identifiers, comments,
+  documentation, tests, commit messages, and configuration. For example, write
+  `color`, `behavior`, and `optimize`, not `colour`, `behaviour`, or `optimise`.
+  Where a term comes from an external source (for example the IAB TCF purpose
+  names), match that source's spelling even when it is not US English.
 - Use only example or fictional information in comments, tests, docs, examples,
   and similar non-runtime materials. (eg. for urls use: example.com domains only)
 - Do not write or commit real domains, customer names, credentials,
   configuration values, or other potentially sensitive real-world information in
   comments, tests, docs, or examples.
 
+### Permission model terminology
+
+Permissions are the primitive. A provider declares the permissions it requires
+(`required_permissions`) and the system decides whether each is _set_. Consent
+is only one of several ways a permission may be established. Country or
+jurisdiction rules (a `Granted` group baseline), legitimate interest, or
+configuration can set a permission with no consent at all.
+
+- A provider that needs nothing **requires no permission**. Never write that it
+  "runs without any consent".
+- A gated provider **runs once its required permissions are set**, by whatever
+  method.
+- Reserve "consent" for the consent subsystem (`consent/`, `ConsentContext`,
+  GDPR and TCF strings) where it genuinely means a consent signal. In the
+  permission layer prefer "permission", "set" / "unset", and "signal" (consent
+  is one kind of signal, alongside privacy and opt-out signals).

+## Provider Architecture
+
+Each vendor-differentiated capability is pluggable behind its own trait, so a
+deployment selects an implementation and the core stays neutral:
+
+| Capability            | Trait                                    | Selector            | Built-in (core)                         | Vendor / host crates         |
+| --------------------- | ---------------------------------------- | ------------------- | --------------------------------------- | ---------------------------- |
+| Edge Cookie identity  | `EdgeCookieProvider` (`ec/provider.rs`)  | `[ec] provider`     | HMAC, client-fixed (opt-in, no default) | `crates/edgecookie/<vendor>` |
+| Device detection      | `DeviceProvider` (`ec/device.rs`)        | `[device] provider` | User-Agent only (default)               | `crates/device/<vendor>`     |
+| Geo / IP intelligence | `PlatformGeo` (`platform/traits.rs`)     | `[geo] provider`    | Disabled, no location (default)         | `crates/geo/<vendor>`        |
+
+Principles for adding or changing a provider:
+
+- **Core stays neutral.** The trait and the host-neutral default live in
+  `trusted-server-core`. Host-specific and vendor implementations live in their
+  own crates and are injected by the adapter (for example `build_device_provider`
+  and `build_geo_provider`), so core never depends on a host SDK or a vendor, and
+  the default request path makes no host-specific calls.
+- **Providers read request evidence, not a fixed parameter set.** A provider must
+  be able to see everything about the request it needs (User-Agent, headers, and
+  host signals such as the TLS JA4 and HTTP/2 fingerprints) through an evidence
+  abstraction rather than a hard-coded struct of fields. Host signals come from
+  the host (the Fastly SDK) and are opt-in, so a neutral provider triggers no
+  host fingerprint calls.
+- **Providers are separated by capability but composed per request, and one may
+  need another's output.** Geo resolves the country and region the permission
+  model uses, and the permission model gates whether the Edge Cookie provider
+  runs. Device signals gate Edge Cookie writes (the browser / bot gate). When
+  several vendor providers share a backend (for example a vendor's Edge Cookie,
+  geo, and device provider on one cloud pipeline) they share a single call per
+  request rather than calling independently. Give a provider the inputs and
+  upstream results it needs explicitly, rather than having it reach into globals.

+# Device providers
+
+Device-detection provider crates live here, one per vendor. The Fastly provider
+(`trusted-server-device-fastly`) classifies a request with the host's TLS and
+HTTP/2 fingerprints; future vendor providers (for example
+`crates/device/<vendor>`) slot in alongside it.
+
+The built-in default provider (User-Agent only) ships in `trusted-server-core`
+(`ec::device`). Adapters select and inject the vendor provider via
+`build_device_provider`.
