Highlights

Storage abstraction layer (application/storage/) with LocalStorage (filesystem, unchanged behaviour) and GCSStorage (Google Cloud Storage) implementations
STORAGE_BACKEND config var (local or gcs); GCS_BUCKET_NAME for GCS mode
GCP Secret Manager integration in config.py - secrets pulled automatically when GOOGLE_CLOUD_PROJECT is set
ManagedPath class for safe lifecycle management of temp-downloaded files
audio_workspace() context manager on storage backends for ffmpeg/pedalboard processing
Internal job HTTP endpoints for Cloud Scheduler, secured with INTERNAL_TOKEN bearer auth
cloud/ directory with GCP deployment config files
Dockerfile for Cloud Run deployment
database/postgres/base_schema.sql - consolidated full schema
database/postgres/0.5_migration.sql
scripts/add_admin_user.py - helper to bootstrap admin accounts
requirements-gcp.txt with GCP dependencies
Config directory restructure - env/secret files now live under config/; LOCAL_MODE controls which files are loaded

All project file I/O refactored from direct Path operations to storage() backend calls
Embed serving reads HTML via storage().read_embed() instead of send_from_directory
config.py env loading now selects config files based on LOCAL_MODE
database/postgres/0.3_migration.sql renamed from 0.2-0.3_migration.sql

Individual per-table SQL files replaced by base_schema.sql to act as base for migration scripts
