## Description The `CODE_BLOCK_RE` regex in `scripts/pr-governance.py` expects LF after the opening fenced code block. PR bodies authored on Windows can arrive with CRLF line endings, which leaves a `\r` before the `\n` and prevents `has_test_output()` from detecting a valid Test Output block. This normalizes CRLF to LF once when loading the pull request body, before section extraction and code-block matching. A regression test now verifies that a valid PR body with CRLF line endings still passes governance. ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) - [x] Tests only ## Changes Made - Normalize Windows CRLF line endings in `scripts/pr-governance.py` before regex-based validation runs. - Added `test_validate_pull_request_accepts_crlf_test_output_code_block` to prevent regressions. ## Testing - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check`) - [x] Formatting passes (`ruff format --check`) - [x] New tests added for new functionality ### Test Output ```text python -m pytest scripts/tests/test_pr_governance.py scripts/tests/test_pr_health_labels.py scripts/tests/test_pr_health_workflow.py -q 8 passed in 0.06s ruff check scripts/pr-governance.py scripts/tests/test_pr_governance.py scripts/tests/test_pr_health_labels.py scripts/tests/test_pr_health_workflow.py All checks passed! ruff format --check scripts/pr-governance.py scripts/tests/test_pr_governance.py scripts/tests/test_pr_health_labels.py scripts/tests/test_pr_health_workflow.py 4 files already formatted ``` ## Real Behavior Proof - Environment: local Windows 11 checkout, Python 3.13.13. - Exact command / steps: Converted the known-valid governance test body to CRLF line endings and passed it through `validate_pull_request` in the new regression test. - Observed result: The report is valid with no problems, proving the fenced Test Output block is recognized after normalization. - Not tested: GitHub-hosted Windows PR authoring path end to end; the unit test covers the exact CRLF body shape consumed by the validator. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review --------- Co-authored-by: JerrettDavis <mxjerrett@gmail.com> |

Utility scripts bundled with the Headroom repo. Most are one-off operator tools; a few are runnable as part of development workflows.
Reproducing the reconnect storm
repro_codex_replay.py reproduces the multi-agent Codex reconnect/retry storm
against a local Headroom proxy (default http://127.0.0.1:8787), as described
in wiki/plans/2026-04-17-codex-proxy-runtime-analysis.md under "Latest
Correction". Use it to:
- Regression-check that
/livezstays responsive under a cold-start storm. - Empirically tune the Unit 4 pre-upstream semaphore default
(
HEADROOM_ANTHROPIC_PRE_UPSTREAM_CONCURRENCY). - Exercise the Codex WS lifecycle + Anthropic HTTP path simultaneously without needing to replay captured production traffic.
Run
# Default: 8 WS + 4 HTTP clients, 30s storm, p99 /livez must stay <= 500ms.
python scripts/repro_codex_replay.py
# Tighter budget, shorter run:
python scripts/repro_codex_replay.py \
--url http://127.0.0.1:8787 \
--ws-clients 16 \
--anthropic-clients 8 \
--duration 60 \
--livez-threshold-ms 100
# Dump the full summary as JSON for downstream tooling:
python scripts/repro_codex_replay.py --json
Exit code:
0— warmup succeeded (or was skipped), storm ran for the requested duration, and/livezp99 stayed under--livez-threshold-ms.1— soft assertion failed, proxy unreachable, or unhandled exception. Proxy-unreachable is detected and reported within ~5 seconds.
Fixtures
The script loads two hand-crafted, fully synthetic JSON fixtures:
scripts/fixtures/anthropic_replay_body.json— shape of a large agent reconnect replay/v1/messages?beta=truePOST body.scripts/fixtures/codex_response_create_frame.json— first Codex WS frame with the{"type": "response.create", "response": {...}}envelope.
Override via --ws-frame-fixture / --anthropic-body-fixture if you have
captured traffic to replay instead.
Interpretation
/livez p99under threshold means the event loop is not starved during the storm. If it rises with the semaphore unbounded (HEADROOM_ANTHROPIC_PRE_UPSTREAM_CONCURRENCY=10000) and drops back under the default, Unit 4's backpressure is working.Codex WS: openedshould equal--ws-clients.response.completedtypically stays low when upstream auth isn't configured locally — the goal is handshake + relay wiring, not real upstream traffic.Anthropic HTTP: ok_2xx + non_2xx + timed_out + errorsshould roughly equalattempted. Sustained non-zerotimed_outduring the storm is the failure signal the plan targets.
A smoke test at tests/test_scripts/test_repro_codex_replay_smoke.py
exercises the script against a mock FastAPI server on every PR.
