-`integration` owns only true inter-service black-box tests.
-Each suite must raise real service processes, speak only over public HTTP/gRPC/Redis contracts, and avoid imports from `internal/...` packages of tested services.
+End-to-end test suite for the Galaxy platform. The suite drives `gateway`
+from outside and verifies behaviour at the public boundary while
+`backend` and `galaxy/game` run as Docker containers managed by the
+test process via `testcontainers-go`.
+
+## Prerequisites
+
+- A reachable Docker daemon (`DOCKER_HOST` or the local socket).
+- Go toolchain matching the workspace `go.work` directive.
+- Network access for the first run (`postgres:16-alpine`,
+  `axllent/mailpit`, `redis:7-alpine` images are pulled). Subsequent
+  runs reuse the local image cache.
+
+## Run
+
+```bash
+go test ./integration/...
+```
+
+The suite builds three Docker images on demand from the workspace
+sources:
+
+- `galaxy/backend:integration` (`backend/Dockerfile`),
+- `galaxy/gateway:integration` (`gateway/Dockerfile`),
+- `galaxy/game:integration`     (`game/Dockerfile`).
+
+Each image is built once per `go test` invocation, guarded by a
+`sync.Once` inside `testenv`. The first cold run is slow (~2–3 min on
+a developer machine); subsequent runs reuse the layer cache.
+
+## Skipping
+
+Tests skip with a clear message when the Docker daemon is unreachable.
+Subsuites that require a live engine container (`lobby_flow_test.go`)
+also skip when the `galaxy/game` image cannot be built.

+- `testenv/` — fixtures: Postgres, Redis, mailpit, GeoLite2 mmdb,
+  image builders, backend/gateway runners, signed gRPC client (built
+  on top of the public `galaxy/gateway/authn` package, no duplicated
+  canonical-bytes code), mailpit HTTP client, `EnrollPilots` helper
+  for runtime-driven scenarios that need ≥10 members, platform
+  bootstrap.
+- `*_test.go` — one file per cross-service scenario.
 
-## Rules
+The runtime-driven tests (`runtime_lifecycle_test.go`,
+`engine_command_proxy_test.go`) honour the engine's production
+contract `len(races) >= 10`: each registers ten extra pilots with
+synthetic `Player01..Player10` race names and matching emails, has
+the owner invite each one, and has each pilot redeem the invite
+before admin force-start. Cold runs add ~30 s for the ten extra
+mailpit round-trips on top of the engine image build.
 
-- Keep suites black-box. Do not import `galaxy/gateway/internal/...`, `galaxy/authsession/internal/...`, or any other service-owned internal package.
-- Start real binaries from `cmd/...` and talk to them only through their published HTTP, gRPC, and Redis contracts.
-- Put boundary-specific orchestration and assertions into the owning suite package, not into shared helpers.
-- Put only generic process/runtime utilities into `internal/harness`.
-- Put only public-contract helpers into `internal/contracts/...`.
+## Determinism
 
-## Current Boundary Suites
-
-- `gatewayauthsession` verifies the integration boundary between real `Edge Gateway` and real `Auth / Session Service`.
-- `authsessionuser` verifies the integration boundary between real `Auth / Session Service` and real `User Service`.
-- `authsessionmail` verifies the integration boundary between real `Auth / Session Service` and real `Mail Service`.
-- `gatewayauthsessionmail` verifies the public auth flow across real `Edge Gateway`, real `Auth / Session Service`, and real `Mail Service`.
-- `gatewayuser` verifies the direct authenticated self-service boundary between real `Edge Gateway` and real `User Service`.
-- `gatewayauthsessionuser` verifies the full public-auth plus authenticated-account chain across real `Edge Gateway`, real `Auth / Session Service`, and real `User Service`.
-- `notificationgateway` verifies that real `Notification Service` push
-  publication is consumed and fanned out by real `Edge Gateway` for all
-  user-facing push types.
-- `notificationmail` verifies that real `Notification Service` template-mode
-  mail publication is consumed by real `Mail Service` for all notification
-  email types.
-- `notificationuser` verifies that real `Notification Service` enriches
-  recipients through real `User Service` and preserves Redis stream progress
-  semantics for missing or temporarily unavailable users.
-- `gatewayauthsessionusermail` verifies the full public registration chain
-  across real `Edge Gateway`, real `Auth / Session Service`, real
-  `User Service`, and real `Mail Service`, including the regression that
-  auth-code mail bypasses `notification:intents`.
-- `lobbyuser` verifies the synchronous eligibility boundary between real
-  `Game Lobby` and real `User Service`, including the happy path,
-  permanent_block rejection, unknown user, and transient User Service
-  unavailability.
-- `lobbynotification` verifies the producer side of `Game Lobby →
-  notification:intents`, covering all eleven `lobby.*` intent types from
-  applications, invites, member operations, runtime pause, cascade
-  membership block, and the three race-name intents emitted by capability
-  evaluation at game finish and by self-service registration.
-- `lobbyrtm` verifies the asynchronous boundary between real
-  `Game Lobby` and real `Runtime Manager` end-to-end against a real
-  Docker daemon: start_job → engine container → success job_result →
-  game `running`; cascade-blocked owner → stop_job(cancelled) → engine
-  stopped; missing image → failure job_result + admin notification
-  intent → game `start_failed`. Skips automatically on hosts without
-  Docker.
-
-The current fast suites still use one isolated `miniredis` instance plus either
-real downstream processes or external stateful HTTP stubs where appropriate.
-`authsessionmail`, `gatewayauthsessionmail`, `notificationgateway`,
-`notificationmail`, `notificationuser`, `gatewayauthsessionusermail`,
-`lobbyuser`, `lobbynotification`, and `lobbyrtm` are the deliberate
-exceptions: they use one real Redis container through
-`testcontainers-go`, because those boundaries must exercise real Redis
-stream, persistence, or scheduling behavior. `lobbyrtm` additionally
-needs a real Docker daemon and the `galaxy/game` engine image.
-`authsessionmail` additionally contains one targeted SMTP-capture scenario for
-the real `smtp` provider path, while `gatewayauthsessionmail` keeps `Mail
-Service` in `stub` mode and extracts the confirmation code through the trusted
-operator delivery surface.
-
-## Running
-
-Run from the module directory:
-
-```bash
-cd integration
-go test ./gatewayauthsession/...
-go test ./authsessionuser/...
-go test ./authsessionmail/...
-go test ./gatewayauthsessionmail/...
-go test ./gatewayuser/...
-go test ./gatewayauthsessionuser/...
-go test ./notificationgateway/...
-go test ./notificationmail/...
-go test ./notificationuser/...
-go test ./gatewayauthsessionusermail/...
-go test ./lobbyuser/...
-go test ./lobbynotification/...
-go test ./lobbyrtm/...
-```
-
-Useful regression commands after boundary changes:
-
-```bash
-go test ./gatewayauthsession/...
-go test ./authsessionuser/...
-go test ./authsessionmail/...
-go test ./gatewayauthsessionmail/...
-go test ./gatewayuser/...
-go test ./gatewayauthsessionuser/...
-go test ./notificationgateway/...
-go test ./notificationmail/...
-go test ./notificationuser/...
-go test ./gatewayauthsessionusermail/...
-go test ./lobbyuser/...
-go test ./lobbynotification/...
-go test ./lobbyrtm/...
-cd ../gateway && go test ./...
-cd ../authsession && go test ./... -run GatewayCompatibility
-cd ../user && go test ./...
-```
-
-Do not use `go test ./...` from the repository root. The repository is organized through `go.work`, so verification should stay module-scoped.
-
-## Adding A New Boundary Suite
-
-1. Create `integration/<boundary>/` for the new inter-service boundary.
-2. Keep suite-local fixtures, scenario helpers, and assertion helpers inside that package.
-3. Reuse `internal/harness` only for generic concerns such as binary build/run, ports, keys, Redis, and shared external stubs.
-4. Add new helpers to `internal/contracts/<contract>/` only when they describe a reusable public wire contract.
-5. Prefer fast deterministic infrastructure by default: in-memory test doubles, `httptest` stubs, and `miniredis`.
-
-## Real Redis Suites
-
-Fast suites stay on `miniredis` by default.
-When one boundary explicitly needs real Redis semantics, prefer a package-local
-container setup through `testcontainers-go` plus reusable helpers in
-`internal/harness`, as done by `authsessionmail` and
-`gatewayauthsessionmail`.
-
-Current rule of thumb:
-
-- use `miniredis` when the boundary does not depend on Redis persistence or
-  scheduling behavior
-- use `testcontainers-go` only when the real Redis process materially changes
-  the behavior being verified
+- Each test calls `Bootstrap(t)` to spin up a dedicated Postgres,
+  Redis, mailpit, backend and gateway. Cross-test contamination is not
+  possible.
+- Tests do not call `t.Parallel()`. Docker resource pressure makes
+  parallel suites flaky on commodity hardware.
+- Gateway anti-abuse and body-size limits are loosened for the bulk of
+  scenarios (so legitimate flows are not rate-limited mid-test) and
+  intentionally tightened in `gateway_edge_test.go` so each protective
+  mechanism can be observed firing.

-// Package gatewaylobby_test exercises the authenticated Gateway -> Game

-// User Service + real Game Lobby running on testcontainers PostgreSQL
-// and Redis.
-//
-// The boundary contract under test is: a client signs a FlatBuffers
-// `ExecuteCommandRequest` for one of the reserved `lobby.*` message
-// types; Gateway verifies the signature, looks up the device session,
-// resolves the calling `user_id`, routes the command to the Lobby
-// downstream client, and signs the FlatBuffers response. The suite
-// asserts on the gRPC response shape, the signed result envelope, and
-// the decoded FlatBuffers payload.
-//
-// Coverage maps onto `TESTING.md §6` `Gateway <-> Game Lobby`:
-// authenticated platform-level command routing.

-// Package lobbyauthsession_test exercises the authenticated context
-// propagation between Auth/Session Service and Game Lobby. The
-// architecture wires the two services through Gateway: AuthSession
-// owns the device-session lifecycle, Gateway projects sessions into
-// its cache and signs request envelopes, and Lobby reads the
-// resolved `X-User-Id` from the gateway-authenticated downstream
-// hop.
-//
-// The boundary contract under test is: revoking a device session
-// through AuthSession's internal API removes the session projection
-// from the gateway cache, after which Gateway refuses to route any
-// subsequent `lobby.*` command for that session. The suite asserts
-// the boundary on the public surfaces: AuthSession internal REST,
-// Gateway authenticated gRPC, and Lobby state via direct REST
-// observation.
-//
-// Coverage maps onto `TESTING.md §6` `Lobby ↔ Auth/Session`:
-// "authenticated context correctly propagated from gateway".

-// Package lobbyrtmnotification_test exercises the failure-with-

-// publishes a start job, Runtime Manager fails to pull the engine
-// image, RTM publishes both a failure `runtime:job_results` envelope
-// AND a `runtime.image_pull_failed` admin notification intent on
-// `notification:intents`. The Notification Service consumes the intent
-// and routes it to Mail Service, where the resulting delivery is
-// observable on the public list-deliveries surface.
-//
-// The suite proves the same Redis bus carries both flows correctly
-// when all three services are booted together — the union of
-// `integration/lobbyrtm` (which uses a stub notification) and
-// `integration/rtmanagernotification` (which has no Lobby).

-// real Mail Service + real User Service running on testcontainers
-// PostgreSQL and Redis, with a real Docker daemon for RTM's readiness
-// pings.
-//
-// The boundary contract under test is: when a start job points at an
-// unresolvable image, RTM publishes one `runtime.image_pull_failed`
-// admin-only notification intent on `notification:intents`; the
-// Notification Service consumes the intent, resolves the admin email
-// recipient list from configuration, and hands the delivery to Mail
-// Service in template-mode. The suite asserts the wire shape on
-// `notification:intents` and the resulting Mail delivery record.
-//
-// Game Master is not booted: RTM emits the intent itself; Notification
-// resolves the audience from `NOTIFICATION_ADMIN_EMAILS_*`; the
-// scenario needs no user-targeted resolution.
