Each element owns its own `EventBroker` (`src/EventBroker.js`) with exchanges named `event`, `run`, `format`, `execution`, and `api`. Per-element factories wire these up: `DefinitionBroker`, `ProcessBroker`, `ActivityBroker`, `MessageFlowBroker`. + +Execution is driven by publishing routing keys like `execute.start`, `execute.completed`, `execute.error`, `run.enter`, `run.end`, `run.discard`, and subscribing via `broker.subscribeTmp()` / `subscribeOnce()`. Messages with `mandatory: true` surface errors if undelivered. The `EventBroker` exposes convenience methods: `on`, `once`, `waitFor`, `emit`, `emitFatal`. If you try to read `ActivityExecution` or `ProcessExecution` as imperative code you will get lost — keep the publish/subscribe model in mind. + +**Do not read synchronous queue/exchange state off the broker** (`queue.messageCount`, `consumerCount`, `peek`, etc.). These are `smqp` conveniences a host that swaps in a real AMQP-compliant broker will not provide. Track what you need in execution state instead — e.g. `consumeInbound` keys the consumer assertion off the `initialized` counter, not a pending-message count on `inbound-q`. Publishing, subscribing, asserting/cancelling consumers, and `queueMessage` are all fine; reading queue depth is not. + +### Activity vs Behaviour + +An element type like `ServiceTask` is not a class. It is a factory function that returns an `Activity` constructed with a `Behaviour` class: + +- `Activity` holds structural info: id, type, inbound/outbound flows, broker, lifecycle state. +- `Behaviour` implements the element-specific `execute(executeMessage)` logic, publishing results back through the broker. + +When an activity is activated, `ActivityExecution` instantiates the Behaviour and calls its `execute`. To replace an element type entirely, supply a new Behaviour — see `docs/Extend.md`. + +To identify an element's kind at runtime, compare its `Behaviour` (`entity.Behaviour === StartEvent`) rather than the `type` string — type strings can be customized via the `types` extension. + +### `Context` and `Environment` + +- `src/Context.js` is a per-execution **registry and lazy factory**. It stores activities, flows, and processes in `refs` Maps and instantiates them on first access via `upsertActivity` / `upsertSequenceFlow` / `upsertProcess`. It bridges the parsed moddle context (from `bpmn-moddle` via `moddle-context-serializer`) to runtime instances and wires extensions through `ExtensionsMapper`. Contexts are cheap to clone and are isolated per execution scope. +- `src/Environment.js` holds global execution config: `variables`, injected `services`, `timers`, `Scripts` engine, `expressions`, `Logger` factory, and settings such as `batchSize`. Cloned and merged per Definition. + +### Api objects + +`src/Api.js` produces `ActivityApi` / `ProcessApi` / `DefinitionApi` / `FlowApi`. These are lightweight wrappers over broker messages that event listeners receive (e.g. `definition.on('end', api => …)`). They expose `.signal()`, `.cancel()`, `.fail()`, `.stop()`, `.discard()`, `.resolveExpression()` and serialize running state via `content` and `messageProperties`. + +### Extension models + +Documented in `docs/Extend.md` and `docs/Extension.md`: + +1. **Replace a Behaviour** by passing `{ types: { 'bpmn:StartEvent': MyStartEvent } }` to `Definition`. Use when you need full control over an element's execution. +2. **Non-invasive extension hooks** via `{ extensions: { myExt(activity, context) { … } } }`. Each extension runs once per activity after instantiation and typically attaches listeners or publishes format messages — used for cross-cutting concerns (forms, logging, output capture). + +### State & behavioral invariants + +- **No flow discards.** Outbound sequence flows are never discarded; flow and activity `discarded` counters stay `0`. There is no `skipDiscard` setting. Parallel joins rely on cached gateway peers, not on discarded flows. +- **Activities are armed through the inbound queue, then run consumer-driven.** Both start activities (`isStart`, no inbound trigger) and link catch events are armed by `Activity.init()`: it mints an executionId, emits the `init` event (whose placeholder in the process's `postponed` set blocks premature completion), increments an `initialized` counter, and queues a non-persistent `activity.init` message carrying that id (plus the activity `id`) on the activity's own `inbound-q`. The run is then driven by the inbound consumer: the idempotent `consumeInbound()` asserts the consumer when there are inbound triggers, or — even without sequence-flow triggers — when the activity is `initialized` (it reads the `initialized` counter rather than probing `inbound-q` for a pending-message count, so no synchronous smqp-only property is touched), and `_onInbound`'s `activity.init` case decrements the counter and calls `run()` with the carried id. `ProcessExecution._start` arms start activities this way (`init()` then `consumeInbound()`, no direct `run()`). A throwing link publishes `activity.link`; the catch's construction-time inbound-trigger handler calls the catch's own `init()` to arm it identically — there is no `activity.relink`. The `initialized` getter reads the counter (exec-state, not persisted); since the `activity.init` trigger is `persistent: false` it is dropped on recover and never re-consumed, so counter and trigger reset together (a stop/resume while armed cannot desync them). +- **`run()` executionId resolution.** `run(runContent)` uses `runContent.initExecutionId` when `runContent.id` equals the activity's own id, otherwise mints a fresh `getUniqueId(id)`. The init/link handoff (`_onInbound`) always passes a matching `id`, so the reserved id is honoured; every other caller (e.g. delegated event runs passing `run(content.message)`) carries no matching id and gets a fresh one. `run()` does **not** peek the inbound queue, and there is no `initExecutionId` exec-state key. `initExecutionId` is **destructured out** of `runContent` so it never reaches the `run.enter`/`run.start` content (it would otherwise leak through `_createMessage`, which only overwrites `id`/`type`/flags, into every downstream message and saved state). +- **Multiple start events are mutually exclusive entry points.** The first start event to fire discards the others still armed, so two start branches can never both run. +- **`stateVersion`.** `Definition.getState()` stamps `stateVersion` (the package major, hardcoded in `src/constants.js`); recovering an older major triggers migrations (e.g. start event reconciliation on resume). Unstamped legacy states are treated as version `0`. Bump the constant on each major release. + +## Testing patterns + +- Framework: mocha + `mocha-cakes-2` BDD UI. `Feature` / `Scenario` / `Given` / `When` / `Then` / `And` / `But` are globals in test files (declared in `eslint.config.js`). Chai `expect` is registered globally via `test/helpers/setup.js`. +- Layout: scenario-style coverage in `test/feature/*.js`; unit tests mirror the `src/` directory tree (`test/activity`, `test/process`, `test/gateways`, `test/tasks`, `test/eventDefinitions`, `test/flows`, …). +- BPMN sources: raw XML templates in `test/helpers/factory.js` (helpers like `factory.valid()`, `factory.userTask()`, `factory.resource('name')`) plus `.bpmn` files under `test/resources/`. +- Primary helper: `test/helpers/testHelpers.js` — `context(source, options)` parses BPMN via `bpmn-moddle`, serializes via `moddle-context-serializer`, and returns a runtime `Context`.
