# pre-push hook: validate Vikunja task exists and tests are fast.
#
# This catches issues that would otherwise only surface in CI:
#   - Branch name missing task ID (e.g., GRM-N)
#   - Vikunja task does not exist for the task ID in the branch name
#   - Unit tests too slow (total > 4s, per-test > 0.5s)
#
# Uses devx.tools.pre_push_check for reusable validation logic.
# Project config (task prefix, Vikunja project ID) is read from
# [tool.devx] in pyproject.toml by devx.config — no hardcoded values here.
#
# Bootstrap resilience: if devx is not importable (e.g., during devx
# upgrades), the hook prints a warning and allows the push.

# Determine the branch being pushed
