glm-5.1 1306716897 Decompose architecture into atomic, dependency-ordered tasks
19 tasks covering core testing, Redis hardening, WebSocket client/server
adapters, Worker adapter, and final review gates. Iroh adapters are tracked
as a deferred placeholder blocked on the @alkdev/iroh fork.

Phases: core validation → Redis hardening → review gate → WebSocket
adapters → review gate → Worker adapter → review gate → final validation.

Description

The Redis event target adapter (event-target-redis.ts) is implemented but has zero tests. The architecture doc lists 7 specific test scenarios. Tests need a running Redis instance or a mock. Since this is a dev dependency, we can use ioredis-mock or start a Redis container in CI. The test strategy needs to handle the Redis dependency.

The architecture specifies these test scenarios:

  1. Publish path — dispatchEvent sends to Redis with correct channel and serialized envelope
  2. Subscribe path — addEventListener subscribes to Redis, onMessage dispatches to local listeners
  3. Unsubscribe — removeEventListener unsubscribes from Redis when no listeners remain for a topic
  4. Topic scoping — type:id topics are correctly formed
  5. Envelope serialization — full { type, id, payload } round-trips through JSON
  6. Multiple listeners — multiple listeners on same topic, single Redis subscribe
  7. Error propagation — what happens on connection failure

Note: test 7 (error propagation) is partially blocked by the missing error handling in the current implementation (tracked in task redis-channel-prefix-and-error-handling). The test should exist but may need to be adjusted once error handling is added.

Acceptance Criteria

  • test/event-target-redis.test.ts exists and passes
  • Test approach for Redis dependency is decided (mock, container, or ioredis-mock)
  • Test: dispatchEvent publishes correct channel and serialized envelope
  • Test: addEventListener subscribes to Redis and dispatches to local listeners
  • Test: removeEventListener unsubscribes from Redis when no listeners remain
  • Test: type:id topic scoping works correctly
  • Test: EventEnvelope round-trips through JSON serialization
  • Test: multiple listeners on same topic result in single Redis subscribe
  • Test: custom serializer option works
