Summary

  • Add StorageBackend abstraction with LocalStorageBackend and S3StorageBackend implementations
  • STORAGE_BACKEND=local (default) preserves identical behavior to current implementation
  • STORAGE_BACKEND=s3 reads/writes PDFs to S3-compatible bucket via boto3
  • serp_api.py updated to use storage abstraction for all PDF operations
  • parse_patent_pdf handles both local paths and S3 URIs (reads to BytesIO)
  • Optional MinIO service in docker-compose.yml (activate with --profile s3)
  • New env vars documented in .env.example

Closes #38

Test plan

  • STORAGE_BACKEND=local produces identical behavior
  • STORAGE_BACKEND=s3 with MinIO reads/writes PDFs to bucket
  • docker compose --profile s3 up -d minio starts MinIO
  • Existing tests pass with STORAGE_BACKEND=local
## Summary - Add `StorageBackend` abstraction with `LocalStorageBackend` and `S3StorageBackend` implementations - `STORAGE_BACKEND=local` (default) preserves identical behavior to current implementation - `STORAGE_BACKEND=s3` reads/writes PDFs to S3-compatible bucket via boto3 - `serp_api.py` updated to use storage abstraction for all PDF operations - `parse_patent_pdf` handles both local paths and S3 URIs (reads to BytesIO) - Optional MinIO service in `docker-compose.yml` (activate with `--profile s3`) - New env vars documented in `.env.example` Closes #38 ## Test plan - [ ] `STORAGE_BACKEND=local` produces identical behavior - [ ] `STORAGE_BACKEND=s3` with MinIO reads/writes PDFs to bucket - [ ] `docker compose --profile s3 up -d minio` starts MinIO - [ ] Existing tests pass with `STORAGE_BACKEND=local`

feat: add S3/MinIO object storage support for patent PDFs 9a43f85259 
Introduce a StorageBackend abstraction (local filesystem and S3) for
patent PDF storage. When STORAGE_BACKEND=s3, PDFs are read/written via
boto3 to an S3-compatible bucket instead of the local filesystem.

- Add SPARC/storage.py with LocalStorageBackend and S3StorageBackend
- Update serp_api.py save_patents and parse_patent_pdf to use storage
- Add storage config vars to config.py and .env.example
- Add optional MinIO service to docker-compose.yml (--profile s3)
- Add boto3 to requirements.txt

Closes leeworks-agents/SPARC#38

Code Review: PASS -- Good storage abstraction: StorageBackend ABC with Local and S3 implementations is clean. Factory function get_storage_backend() reads from config. Module-level lazy init in serp_api.py avoids import-time side effects. S3 backend handles bucket auto-creation. MinIO docker-compose profile with --profile s3 is a good pattern. Note: boto3 added as required dependency in requirements.txt -- this is fine since it is only imported lazily in S3StorageBackend.init. Ready to merge. Closes #38.

merge: resolve conflicts for S3 storage branch with main a6c92fde9f 
Integrates S3/MinIO storage backend with structured logging changes
from main. Both boto3 and apscheduler retained in requirements.txt.
