migration

Familiar local defaults, fully open source.

Overcast intentionally uses the same default API port and common endpoint conventions. The goal is a small, reversible trial: change the container image, point supported AWS-compatible clients at Overcast, and use the support matrix to understand service gaps before relying on a workflow.

>_ shared client configuration

export AWS_ENDPOINT_URL=http://localhost:4566
export AWS_ACCESS_KEY_ID=test
export AWS_SECRET_ACCESS_KEY=test
export AWS_DEFAULT_REGION=us-east-1

What stays familiar

Port 4566, endpoint-url based clients, Docker-first startup, and common local emulator environment mappings.

What changes

No cloud account, no auth token, no telemetry, and no paid feature gates. Missing API surface is documented instead of hidden.
