## Description Running Claude Code (Anthropic) and Codex (OpenAI) against the **same** Headroom proxy instance on one port produced incorrect, unstable dashboard data. The proxy core is provider-isolated and multi-provider-safe by design; the defect was in the observability layer. The Codex `/v1/responses` **WebSocket** handler was the only path in the proxy that wrote to the request logger by hand instead of through the unified `emit_request_outcome` funnel, and it did so twice per session close: the per-turn funnel record plus an unconditional cumulative session-summary `RequestLog`. This PR removes the duplicate summary log so Codex WS emits exactly one request log per turn, matching the HTTP provider paths. ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - Dropped the duplicate cumulative session-summary `RequestLog` in the Codex WS handler while preserving the per-turn `emit_request_outcome` path. - Preserved gated `request_messages` and `turn_id` on residual outcomes so dashboard telemetry keeps the useful attribution without double-counting tokens. - Ensured explicit `--anyllm-provider` wins over a leaked `HEADROOM_ANYLLM_PROVIDER` environment variable. - Registered retry delay settings that had drifted out of the settings registry. - Hardened tests against developer-shell `HEADROOM_*` / `ANTHROPIC_CUSTOM_HEADERS` leakage and stabilized several focused proxy/wrap test fixtures. ## Testing - [x] Unit tests pass (`pytest`) - [x] Linting passes (`ruff check .`) - [ ] Type checking passes (`mypy headroom`) - [x] New tests added for new functionality - [x] Manual testing performed ### Test Output ```text $ .venv/bin/pytest tests/ -q -p no:cacheprovider 8529 passed, 537 skipped, 5831 warnings in 276.25s (0:04:36) $ .venv/bin/ruff check <touched files> All checks passed! ``` ## Real Behavior Proof - Environment: macOS (Darwin 25.4.0), Python 3.13.14, pytest 9.0.3, ruff via project venv, branch `fix/multi-provider-runtime`. - Exact command / steps: Ran the full test suite without pytest cache provider and Ruff on all touched files; used `git stash` to confirm the stale fake-config failures pre-existed this change. - Observed result: Full suite passed with no failures; Ruff passed; Codex WS now routes end-of-session logging through `emit_request_outcome`, emitting one request log per turn with the same accounting model as Anthropic HTTP turns. - Not tested: Live simultaneous Claude + Codex dashboard run. `mypy headroom` was not run to completion; a scoped run reported one pre-existing `settings_store.py:470` coercion error outside this diff. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [x] My code follows the project's style guidelines - [x] I have performed a self-review of my code - [x] I have commented my code, particularly in hard-to-understand areas - [ ] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [ ] I have updated the CHANGELOG.md if applicable ## Screenshots (if applicable) N/A - server-side observability fix; no UI markup changed. ## Additional Notes - The proxy's multi-provider routing, header/auth isolation, and per-model cache keying are already correct and unchanged here; only the WS observability write path was double-counting. - Architectural assessment: `plans/reports/research-260714-0004-multi-provider-upstream-compression-report.md`; root-cause + resolution trail: `plans/reports/debug-assessment-260714-0011-dashboard-instability-mixed-claude-codex-report.md`. - No live simultaneous Claude + Codex dashboard run was performed; validation is from test coverage and code review of the WS logging path. --------- Co-authored-by: JerrettDavis <mxjerrett@gmail.com> |
