From 67c93ff6b5a1815e52759aa4be0c554cd9802580 Mon Sep 17 00:00:00 2001 From: GitHub Actions Date: Wed, 28 Jan 2026 21:45:57 +0000 Subject: [PATCH] hotfix: Route-Aware Verification and jq Dependency - Added a new implementation report for the Cerberus TC-2 test fix detailing the changes made to handle the break glass protocol's dual-route structure. - Modified `scripts/cerberus_integration.sh` to replace naive byte-position checking with route-aware verification. - Introduced a hard requirement for jq, including error handling for its absence. - Implemented emergency route detection using exact path matching. - Enhanced defensive programming practices with JSON validation, route structure checks, and numeric validations. - Improved logging and output for better debugging and clarity. - Verified handler order within main routes while skipping emergency routes. - Updated test results and compliance with specifications in the implementation report. --- docs/plans/current_spec.md | 1204 +++++++++++++++++ .../cerberus_tc2_fix_implementation_report.md | 222 +++ scripts/cerberus_integration.sh | 183 ++- 3 files changed, 1569 insertions(+), 40 deletions(-) create mode 100644 docs/plans/current_spec.md create mode 100644 docs/reports/cerberus_tc2_fix_implementation_report.md diff --git a/docs/plans/current_spec.md b/docs/plans/current_spec.md new file mode 100644 index 00000000..2537584f --- /dev/null +++ b/docs/plans/current_spec.md @@ -0,0 +1,1204 @@ +# Cerberus Integration Test Failure - Handler Ordering After Break Glass Protocol + +**Status**: ACTIVE - ANALYSIS COMPLETE +**Priority**: HIGH 🔴 - CI Blocking +**Created**: 2026-01-28 +**Updated**: 2026-01-28 +**Bug**: Cerberus integration test TC-2 fails due to emergency route handler ordering +**CI Run**: https://github.com/Wikid82/Charon/actions/runs/21453152384/job/61786891302 +**Branch**: feature/beta-release +**PR**: https://github.com/Wikid82/Charon/pull/550 + +--- + +## Executive Summary + +The Cerberus integration test (**TC-2: Verify Handler Order in Caddy Config**) is failing in CI after the break glass protocol implementation.
