# Trigger

**Test family:** `TRG`

- **TRG-001** Matching event triggers once with correct object/version/actor; nonmatching near-neighbor does not.
- **TRG-002** Duplicate, delayed, reordered, missing, replayed, and burst events follow stated delivery semantics.
- **TRG-003** Event occurring before enable, during pause, during edit, or after disable follows catch-up policy.
- **TRG-004** Trigger does not recursively consume its own action unless explicitly bounded.
- **TRG-005** Filter/condition evaluates event-time versus current-state data intentionally.
- **TRG-006** Unauthorized or forged event cannot trigger privileged action; webhook signature/replay window are enforced.
- **TRG-007** Concurrency/debounce/throttle/batch windows preserve required events and explain dropped/coalesced ones.

## Comprehensive per-item coverage

- **TRG-008** Exercise no match, one match, many matches, and boundary-size batches with ordinary and adversarial records.
- **TRG-009** Use text values containing emoticons, emoji, kaomoji, RTL, combining marks, quotes, delimiters, and newlines; preserve comparison and substitution semantics.
- **TRG-010** Deliver the same event once, twice, late, out of order, and after replay; define deduplication and event-time behavior.
- **TRG-011** Race matching events and concurrent workflow instances against the same record; prevent lost updates and duplicate effects.
- **TRG-012** Retry before commit, after commit before acknowledgment, and after downstream partial success; use stable idempotency.
- **TRG-013** Change the condition, template, permission, owner, or target after scheduling but before execution; define snapshot versus latest semantics.
- **TRG-014** Run across daylight-saving gaps/folds, leap day, month end, differing tenant zones, clock skew, and delayed workers.
- **TRG-015** Pause, resume, disable, edit, clone, publish, roll back, and delete while runs are queued or active; preserve version identity.
- **TRG-016** Create direct, indirect, and cross-workflow loops; detect recursion, cap fan-out, and expose why execution stopped.
- **TRG-017** Test missing fields, nulls, type changes, unknown enums, deleted references, schema migrations, and malformed payloads.
- **TRG-018** Run as creator, owner, service identity, changed-role user, removed user, and least-privilege actor; define execution authority explicitly.
- **TRG-019** Cross tenant, workspace, region, and environment boundaries only when explicitly authorized; prevent shared caches or queues from leaking data.
- **TRG-020** Force dependency timeout, rate limit, quota, authentication expiry, malformed response, and permanent rejection; route each to a defined failure path.
- **TRG-021** Verify compensation or rollback for partial multi-step work, including a compensation failure and manual recovery.
- **TRG-022** Measure queue delay, execution latency, throughput, fan-out, backlog, and recovery under the supported load envelope.
- **TRG-023** Provide dry-run or preview where consequences justify it; identify evaluated inputs, matched conditions, and proposed actions without mutation.
- **TRG-024** Verify alerting distinguishes user-data failure, configuration failure, platform failure, and exhausted retries without notification storms.
- **TRG-025** Record immutable version, trigger/event ID, evaluated conditions, actor, permissions, each attempt, side effect, and final outcome without secrets.
- **TRG-026** Replay a historical event against the same and newer definition in an isolated mode; make semantic changes visible.
- **TRG-027** Recover after worker crash, queue redelivery, regional failover, and prolonged outage without losing or duplicating committed work.
