# OpenCodeReview - GitFlic CI Merge Request Auto-Review Demo
#
# Reviews Merge Requests with OpenCodeReview and posts the findings onto the
# MR as discussions (inline where possible). The posting glue lives in the CI
# layer, in post_review.py next to this file -- consistent with the GitHub and
# GitLab examples, which keep platform-specific publishing out of the `ocr`
# binary.
#
# Setup:
#   - Commit BOTH this file and post_review.py into your repository (adjust the
#     `python3 post_review.py` path below if you place the script elsewhere).
#   - Enable "Merge Request Pipeline" in Project Settings -> CI/CD Settings.
#   - Use a runner able to run the node:20 image (it ships node, python3 and git),
#     or any shell runner with node 20+, python3 and git available.
#
# Required CI/CD Variables (Settings -> CI/CD -> Variables):
#   OCR_LLM_URL        - LLM API endpoint (e.g., https://api.openai.com/v1/chat/completions)
#   OCR_LLM_AUTH_TOKEN - Authentication token for the LLM API
#   GITFLIC_TOKEN      - GitFlic access token used to post MR discussions
#
# Optional CI/CD Variables:
#   OCR_LLM_MODEL      - Model name (e.g., gpt-4o)
#   GITFLIC_API_URL    - GitFlic REST API base URL; only needed for self-hosted
#                        instances (defaults to https://api.gitflic.ru)
#
# post_review.py picks up the MR context automatically from the predefined
# GitFlic CI variables: CI_PROJECT_NAMESPACE, CI_PROJECT_NAME,
# CI_MERGE_REQUEST_LOCAL_ID, CI_MERGE_REQUEST_TARGET_BRANCH_NAME, CI_COMMIT_SHA.
