Context

Several backend modules use print() for diagnostic output. This means log levels cannot be filtered, output format is inconsistent, and log aggregation tools (e.g., Loki, CloudWatch) cannot parse structured fields.

Roadmap reference: ROADMAP.md -- P2 Backend -- "Add structured logging"

What to do

  1. Add a logging configuration module (or extend config.py) that sets up a root logger with a configurable level (LOG_LEVEL env var, defaulting to INFO).
  2. In analyzer.py, serp_api.py, and llm.py, replace every print(...) call with the appropriate logging.getLogger(__name__).<level>(...) call.
  3. Use structured key-value pairs where relevant (e.g., logger.info("patent fetched", extra={"patent_id": pid})).
  4. Optionally configure a JSON formatter when LOG_FORMAT=json is set.

Acceptance criteria

  • No print() calls remain in the three target modules.
  • Running the API with LOG_LEVEL=DEBUG emits debug messages; LOG_LEVEL=WARNING suppresses info messages.
  • Existing tests still pass.
## Context Several backend modules use `print()` for diagnostic output.

Roadmap reference: ROADMAP.md -- P2 Backend -- "Add structured logging" ## What to do 1. Add a logging configuration module (or extend `config.py`) that sets up a root logger with a configurable level (`LOG_LEVEL` env var, defaulting to `INFO`). 2. In `analyzer.py`, `serp_api.py`, and `llm.py`, replace every `print(...)` call with the appropriate `logging.getLogger(__name__).<level>(...)` call. 3. Use structured key-value pairs where relevant (e.g., `logger.info("patent fetched", extra={"patent_id": pid})`). 4. Optionally configure a JSON formatter when `LOG_FORMAT=json` is set. ## Acceptance criteria - No `print()` calls remain in the three target modules. - Running the API with `LOG_LEVEL=DEBUG` emits debug messages; `LOG_LEVEL=WARNING` suppresses info messages. - Existing tests still pass.

Triage: Assigned to @developer. Reason: P2 refactor, small - replace print with logging.

Already implemented -- closing.

All modules in the SPARC/ package use logging.getLogger(__name__) instead of print(). A codebase search for print() calls in SPARC/ returns zero results. Specifically: analyzer.py, serp_api.py, and llm.py all import logging and use logger.info(), logger.warning(), and logger.error(). The config.py module configures the logging level via the LOG_LEVEL environment variable.

No further work needed.
