Python SDK for shellbound Django applications. Provides ShellApp, ShardContext, ShellboundMiddleware. Emits Chronicle events to stdout in dev mode. Includes fix for IndexError in apps.py when DJANGO_SETTINGS_MODULE has no dots (e.g. instance_settings). Shard name now falls back safely without eager default argument parsing. Implements SHELLBOUND-APP-0001 §4 (dev mode). Wired into entropyopposition as of 2026-03-18.
