python-dotenv>=1.0.1

# --- Authentication ---
# Signs/verifies the access tokens issued by /api/auth/login. Pure Python, no
# compiled extension - nothing extra to build on the slim image. Password
# hashing uses hashlib.pbkdf2_hmac from the standard library, so there is
# deliberately no bcrypt/argon2/passlib dependency here.
PyJWT>=2.9.0

# --- MCP (Model Context Protocol) ---
# Serves the catalog as tools for AI clients at /mcp (see app/mcp_server.py),
# mounted onto the FastAPI app so it needs no separate process or container.
# Requires Python >=3.10; the Dockerfile's python:3.11-slim satisfies that, and
# app/main.py degrades to serving the REST API alone if the import fails.

# --- Embeddings (RAG retrieval) ---
# sentence-transformers pulls in its own CPU-friendly torch wheel
# automatically - no need to pin torch separately. Imports are LAZY
# (see app/services/embeddings_service.py) so the API still boots fast
# even before this is installed/loaded.

# --- Catalog ingestion pipeline (discovery / images / pricing) ---
# Only required if you plan to run cli/ingest_brand.py or
# POST /api/catalog/generate to pull in NEW brands. If you only ever use
# the bundled seed data (scripts/seed_sample_data.py) + RAG chat/search,
# you can skip everything below this line.
# Retry/backoff for the barcode enrichment sources
# (app/services/enrichment/barcode/retry.py). This is NOT an optional extra:
# retry.py imports it at module scope, and that module is reached from
# app/main.py's own import of the store_catalog router - so a missing tenacity
# is not a degraded feature, it is the container exiting 1 on boot with
# ModuleNotFoundError before uvicorn ever binds a socket. Swarm then restarts
# it, and each restart re-runs ~21s of pandas/scipy/sklearn imports, which on a
# 1-vCPU host reads as pinned-at-100% CPU rather than as a crash.

# Playwright (Python) - last-resort image-search fallback only.
# Run `playwright install chromium` once after pip install to enable it;
# the pipeline works fine without it (just one fewer fallback source).
# playwright>=1.47.0
# Commented out, not deleted. It is the last-resort image-search tier, and the
# Dockerfile never installs its browser binary - so in a container the tier is
# skipped at runtime no matter what, while the package still costs 137MB. The
# import is lazy (app/services/playwright_image_fallback.py does it inside the
# function), so its absence is handled on the existing "not installed" path.
# Uncomment, and run `playwright install chromium`, if you ever want that tier.

# --- implicit dependency (app/intelligence/*.py imports these) but was ---

scikit-learn>=1.5.2

# pandas' Excel readers are optional extras it does not install itself, and the
# upload endpoints (/api/user/products/upload-file, /api/upload/*) accept .xlsx
# and .xls. Undeclared, they happened to be present in some environments and
# absent in others - so an Excel upload that worked locally failed in the
# container with "Missing optional dependency 'openpyxl'". openpyxl reads
# .xlsx/.xlsm; xlrd is only for the legacy .xls format.

# --- Dev/test tooling ---
# Moved to requirements-dev.txt so the Docker image does not carry the test
# stack it can never run. To work on this project, install both:
#     pip install -r requirements.txt -r requirements-dev.txt
