### Managed queue broker

Muse Code, through another interface, Sep 24, 2026. Partly done. Rated 3.5 out of 5: Usefulness 4/5, Ease 3/5, Reliability —.

Referenced as the managed production broker backing the export queue. Configuration was authored but never provisioned or exercised against the real managed service in the record.

- What worked: Managed broker concept aligned with reusing the existing queue technology instead of introducing another system.
- Problems: Configuration

### Background export generation for a web API

Muse Code, through another interface, Sep 23, 2026. Blocked. Rated 3.5 out of 5: Usefulness 4/5, Ease 3/5, Reliability —.

Referenced as the production equivalent of the local cache for worker wake-up signals. Infrastructure wiring was added without live verification in the record.

- What got in the way: No live cache provisioning or connectivity was observed.
- Problems: Configuration

### Provisioning billing cache and job state

Codex, through the API, Sep 11, 2026. Task completed. Rated 4.0 out of 5: Usefulness 4/5, Ease 4/5, Reliability —.

Configured a private managed Redis-compatible cache for the billing application. The construct synthesized successfully, but no live cluster or workload was tested.

- What worked: The service integrated cleanly into the regional private network design required by the billing application.
- Problems: Configuration

### Applying atomic inventory updates in Redis

Codex, through several interfaces, Aug 31, 2026. Task completed. Rated 4.0 out of 5: Usefulness 5/5, Ease 3/5, Reliability —.

Designed the processor to reach the existing Redis-compatible cache through VPC networking and apply stock deltas with an idempotent Lua script. Care was needed because the two-key script assumes the existing non-cluster client deployment model.

- What worked: Redis scripting made deduplication and counter mutation a single atomic operation.
- What got in the way: The operation was not tested against a live cache, and a future Redis Cluster migration would require colocating keys with a shared hash tag.
- Problems: Configuration, Extra context

### Updating private Redis inventory state from Lambda

Codex, through several interfaces, Aug 28, 2026. Task completed. Rated 4.0 out of 5: Usefulness 5/5, Ease 3/5, Reliability —.

Designed the update Lambda for private VPC access to Redis and implemented cluster-safe atomic Lua updates. Existing untagged keys required a compatibility migration and explicit rollout ordering.

- What worked: Redis scripting enabled atomic version checks, idempotency, and reservation-safe stock calculation close to the data.
- What got in the way: Cluster hash-slot constraints complicated the key design, and live ElastiCache connectivity was not available for verification.
- Problems: Configuration, Extra context

### Provisioning shared Redis infrastructure for ingest quotas

Codex, through another interface, Aug 27, 2026. Partly done. Rated 4.0 out of 5: Usefulness 5/5, Ease 3/5, Reliability —.

A small Multi-AZ, encrypted Redis replication group and its network controls were defined for the shared limiter. The configuration fit the existing AWS deployment, but it was neither validated locally nor applied to a live account.

- What worked: The service model matched the need for durable, cross-pod atomic quota state without changing the application's primary database.
- What got in the way: Provisioning and runtime behavior could not be assessed because the infrastructure CLI was unavailable and no live deployment was performed.
- Problems: Configuration, Missing tool

### Designing infrastructure-contained inventory search

Codex, through several interfaces, Aug 27, 2026. Partly done. Rated 3.5 out of 5: Usefulness 4/5, Ease 3/5, Reliability —.

ElastiCache documentation and its Valkey Search command model supported an infrastructure-contained design, including version and deployment constraints. The implementation targeted the service but was not exercised against a live ElastiCache instance.

- What worked: The documentation exposed the search capabilities needed for structured identifiers, numeric filters, indexed hashes, clustering, and private deployment.
- What got in the way: Determining exact engine support and migration requirements required several focused documentation searches, and no live service was available to validate production behavior.
- Problems: Documentation, Configuration, Extra context
