Interactive examples

Use these local simulations to compare what happens at a RevoEngine boundary. Start with a guard rejection, a shared concurrency key, or a receiver that loses its response after applying an effect. The scenarios use synthetic data, and their playback ticks are illustrative.

Capacity and duplicate protection

Job concurrency

Change a per-key limit and watch waiting Jobs enter available slots.

Coordination keys

Compare shared capacity with two independent template keys.

Idempotency

Compare a stable business key, a new key per retry and an overly broad key.

Low-code admission

See admission, BUSY and exact release ownership.

Request and execution flows

Explore	Change the scenario	Observe
Endpoint guard	Valid input, invalid input, missing route, denied access, static response	Which boundary stops the request before business execution
SSE	Success, admission failure, failure after opening	HTTP acceptance versus terminal stream outcome
Background work	Accepted work or lost response	Receipt, durable identifier and confirmed completion
Job retry	Error, capacity wait, uncertain effect	New attempt versus the same waiting attempt
Storage	Asynchronous indexing or invalid synchronous CSV	Byte transfer, finalization and structured readiness
Events	Matching filter, non-match, replay	Subscription dispatch and separate target outcome
Schedules	Active or paused	Due time, input resolution and later admission

Authoring, state and governance

Explore	What to expect
Widget refresh	Exact requested IDs merge while existing input state remains
Transactions	Local commit or rollback, with external effects outside the boundary
Bounded reads	A preview differs from a complete cursor scan
Hosted revisions	Saved source becomes eligible only after readiness and activation
Action approval	Approve, reject or re-review a stale proposal
Authentication	Identity, target permission and request validation are separate checks

Routing and delivery

Explore	What to change	What to observe
Event filtering	Message values, numeric type, occurrence metadata, all/any	Exact conditions that admit this subscription
Dispatch and Replay	Redeliver an occurrence or create a Replay	Reused versus new initial child Jobs
Outbound Webhooks	Receiver deduplication, lost response, retry cap, stop on 401	HTTP attempts versus receiver business effects

Metadata and correlation explains which values belong in definitions, published Events, messages and outbound requests.

Data, access and client behavior

Explore	What to expect
Permission and ACL	A platform role alone does not admit a restricted resource
Vault grants	Connecting an account and granting a consumer are separate steps
Realtime reconnect	Refetch authoritative state after gaps; reject older local projections
Application cache	Rebuild a miss; atomic insertion does not deduplicate preceding work
View source actions	Review a workset; re-preview after the View or materialization changes
SDK batches	Independent results versus stop-on-error, without rollback
CLI synchronization	Fast-forward a clean copy or resolve divergent changes
Native tests	Test evidence belongs to captured source and does not activate it
Execution evidence	Receipt, terminal execution and durable result; disclose coverage gaps
MCP sessions	Initialize under the current credential and inspect the tool outcome

Use Next step to inspect a boundary. Play advances the example at a steady pace. Select an earlier stage in a walkthrough or use the example’s reset controls to revisit a result. With reduced motion, use manual steps. Exact fields, defaults, limits and failure semantics remain in the guide beside each demonstration and in Reference. Historical release notes and legal terms are not simulations.
