- **One worker per session** (invariant). Multi-subscriber event fan-out and reconnect-with-replay have shipped and are config-gated: `AllowMultipleEventSubscribers` (default `false`) enables fan-out up to `MaxEventSubscribersPerSession` (default `8`); `DetachGraceSeconds` (default `30`) retains a session after its last subscriber drops so clients can reconnect; `ReplayBufferCapacity` / `ReplayRetentionSeconds` control how much event history the replay ring keeps. Default config is single-subscriber (`AllowMultipleEventSubscribers` off), but detach-grace and replay retention are **on** by default (`DetachGraceSeconds=30`, `ReplayBufferCapacity=1024`, `ReplayRetentionSeconds=300`): a detached session is retained for 30 s and recent events are buffered for reconnect. The reconnect protocol is consumable end-to-end: a resuming `StreamEvents` (via `after_worker_sequence`) that predates the retained ring gets a `ReplayGap` sentinel, and all five official clients surface it as a typed signal. Orphan-worker reattach after a gateway restart is **deferred, not planned** — see `docs/DesignDecisions.md` (Session-Resilience Epic Scope, session-resilience epic Phase 5); the invariant on the next line stands. See `docs/DesignDecisions.md` and `docs/Sessions.md`.
- **Gateway restart does not reattach orphan workers.** The first version terminates orphaned workers on startup; do not design code paths that assume reattachment.
- **No Blazor UI component libraries.** Dashboard uses local Bootstrap CSS/JS only — do not introduce MudBlazor, Radzen, FluentUI, etc.
- **Don't log secrets or full tag values by default.** API keys, passwords, `WriteSecured` payloads, and `AuthenticateUser` credentials must never reach logs. Value logging is opt-in and redacted.

- **Generated code** under `src/ZB.MOM.WW.MxGateway.Contracts/Generated/`, `clients/*/generated*/`, `clients/python/src/zb_mom_ww_mxgateway/generated/`, etc., is build output. Don't hand-edit. To regenerate, build the contracts project (`dotnet build src/ZB.MOM.WW.MxGateway.Contracts/ZB.MOM.WW.MxGateway.Contracts.csproj`) or run the per-client generation step in that client's README.
- **Documentation style** (`StyleGuide.md`): PascalCase filenames, no marketing language, present tense, explain *why* not *what*.
- **Update docs in the same change as the source.** When public APIs, contracts, configuration, build steps, security behavior, event shapes, value conversion, status mapping, or lifecycle rules change, the affected docs (`gateway.md`, `docs/`, client READMEs, design docs) must change in the same commit. Don't leave stale prose describing old behavior.
