Walkthrough

Simplified .dockerignore to focus on version control and environment files. Enhanced Dockerfile with Python runtime optimizations, consolidated dependency installation with build tools for asyncpg, and multi-variable environment declarations. Modified bot.py to implement lazy loading for missing telegram dependencies with runtime errors. Updated docker-compose.yml with postgres health checks and environment file references.

Changes

Cohort / File(s) Summary

Docker Infrastructure
.dockerignore, Dockerfile, docker-compose.yml Streamlined .dockerignore to prioritize version control and environment file patterns; enhanced Dockerfile with PYTHONDONTWRITEBYTECODE and PYTHONUNBUFFERED flags, added build-essential and libpq-dev for asyncpg compilation, consolidated multi-variable ENV declarations; added postgres health check using pg\_isready and env\_file configuration for both postgres and meme-wrangler services with healthy service dependency

Application Dependency Handling
bot.py Introduced lazy-loading error handling via guarded imports under TYPE\_CHECKING condition; added _MissingTelegramModule and _MissingFilters placeholder classes that raise RuntimeError on attribute access or invocation when telegram dependencies are unavailable; reorganized fallback definitions to runtime evaluation instead of import-time assignment

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~25 minutes

bot.py: Lazy-loading mechanism with custom placeholder classes requires verification that runtime errors are triggered correctly and that import guards don't mask legitimate issues
Dockerfile: Consolidation of ENV variables and addition of build dependencies needs validation for asyncpg compilation and proper path configuration
docker-compose.yml: Postgres health check configuration and service dependency chain require testing to ensure startup sequencing works as expected

Poem

🐰 Lazy loads keep the telegram troubles at bay,
Docker tidies its closet in a functional way,
Health checks guard the database with pride,
This bot's now resilient—errors won't hide! 🐇
