# Vector store + local embeddings for RAG, semantic memory, and tool
# selection. Used on core agent paths, so installed by default — the app
# still degrades to keyword fallback if they're ever missing.
# chromadb-client is the lightweight HTTP client (talks to a standalone
# ChromaDB service); fastembed runs local ONNX embeddings.

# Markdown rendering for research reports (src/visual_report.py).
# Imported at module-top so it's a hard core dep, not optional.
markdown
# HTML sanitizer for rendered research reports (src/visual_report.py). Report
# content is untrusted (LLM output over crawled pages) and report pages run
# under a relaxed CSP, so the rendered HTML is allowlist-sanitized.

# Calendar .ics import/export (routes/calendar_routes.py).

# Recurrence rule expansion for calendar events (routes/calendar_routes.py).
# Imported directly as dateutil.rrule — make it explicit even though caldav
# pulls it in transitively.

# CalDAV sync (src/caldav_sync.py). Handles PROPFIND discovery + REPORT
# fetch across Radicale, Nextcloud, Apple, Fastmail; we'd be reinventing
# the protocol without it.

# Built-in servers use the v1 low-level Server decorator API. MCP SDK v2 is a

# starlette.testclient prefers httpx2 since Starlette 1.2.0 and warns on every
# TestClient import when only classic httpx is present. Runtime code keeps
# using `httpx` above; this is test-client only.

# DATABASE_URL defaults to sqlite (core/database.py), but when pointed at an
# external Postgres, SQLAlchemy's postgresql dialect imports psycopg2 inside
# create_engine() and raises ModuleNotFoundError if missing. -binary avoids
# needing libpq-dev/pg_config on the host/image to compile it.
