fix(ci): pin quest commands and retain benchmark base errors - #7710
Benchmark comparisons reported a generic base-build failure without a dedicated build log, and repository gates could resolve a different quest from the build pinned by the checkout.
Approach
Stream and retain the complete base-build diagnostics in each run's base-build.log. Keep the build status separate from the log writer so a failed log write does not discard a successful paired comparison.
Launch and report the dev shell's absolute quest executable without reevaluating the flake per gate. Keep direct skill commands pinned through PATH precedence. Outside the shell, resolve the checkout's Nix package; explicit host toolchains report their executable, version, and repository pin, marking unavailable diagnostic metadata explicitly.
Cover successful, failed, and absent base targets, build diagnostics, worktree cleanup, pinned launchers, host reporting, and missing tools. Remove the completed quest and its link.
Impact
Public API: none.
Wire: none.
No GStreamer source, benchmark workloads, package versions, or quest CLI behavior changed.
Alternatives and choices
Current main already builds the catalog base. The isolated worktree from moq-dev/moq#7445 stays unchanged.
A per-gate nix run was dropped after local review because it repeatedly evaluates and copies the checkout. An absolute executable supplied by the dev shell keeps the exact build cheaply.
The quest Goal allows reporting which build ran, while its Plan describes failing on a mismatch. I preserved the existing explicit host-toolchain opt-out and report its build as unverified. Recommended clearer wording: “Explicit host toolchains report executable, version, and repository pin; build identity is unverified.” This avoids removing Windows/host support or claiming that the shared 0.1.0 version identifies a source revision.
Validation
2026-11-05 iteration: fixed the two CodeRabbit threads only. nix develop --accept-flake-config -c quest gate just ci ff1dda969f09500a01bda448472f0197a74439dc passes every selected lane, including the complete tooling suite. The four real-Cargo base scenarios and all nine launcher tests also pass independently through quest gate. The new log-write failure scenario retains the successful base target and comparison; the Nix-only launcher test skips Windows/Cygwin.
Current unchanged base d0c73e35844c65bdd27bd43cba37431de14fee60 reproduces CARLA’s environment failure under this checkout’s dev shell: nix develop --accept-flake-config -c quest gate bash .tmp/base/demo/carla/sim/python.test.sh exits 1 with the same inherited Nix PYTHONPATH and compiler-path mismatch. The fixture passes when run in the base checkout’s own dev shell. Both python.sh and python.test.sh are identical between the branch and base. This confirms the checkout environment dependence; the existing host-snapshot follow-up below remains applicable.
Full nix develop --accept-flake-config -c quest gate just ci origin/main ran all lanes. All passed except the existing CARLA environment failure documented below and two fixture quote-format lines, subsequently fixed and verified by the passing scoped rerun. The strict flake check passed on this run. No harness environment was cleared.
Merged origin/main without rebasing. Fixed the benchmark fixture to provide .cargo/config.toml, now explicitly read by the merged metadata collector. All three real-Cargo base scenarios pass; the complete repository tooling suite passes.
Current-main catalog comparison from the implementation round: nine unchanged cases, no unavailable targets, with a retained nonempty base-build log.
nix develop --accept-flake-config -c quest gate just ci origin/main: full repository scope. Rust's 11,690 tests pass. Final post-review run: every lane passed except strict local Nix (namespace refusal) and the reproduced base CARLA environment failure. JavaScript tests, C/C++, Kotlin, Go, Dart, Rust, and the complete tooling suite passed. Swift skipped on Linux by design.
CHECK_MODULES=flake just check origin/main: succeeds with check flake (skipped) because this local Nix builder cannot create user namespaces, as expected under the maintainer decision below.
CARLA's demo/carla/sim/python.test.sh fails identically on this branch and unchanged base ac0f04e5dc: the host's BASH_ENV reloads Nix PYTHONPATH into the fixture. Base command: nix develop --accept-flake-config -c bash demo/carla/sim/python.test.sh. No harness environment was cleared for checks.
Refreshed the stale dev-shell snapshot through .codex/hooks/direnv.sh; the final rerun passes JavaScript checks, JavaScript tests, and Worker dry runs. Their base checks also pass.
Review
Claude Code / Claude Opus 5.5, medium effort, session c728ad5e-14ee-48c4-abfe-c3503a74bf9d, round 2 reviewed 2f9f857d040538d20a57e625d6853e4b09dc8980 against origin/main at d0c73e35844c65bdd27bd43cba37431de14fee60: no findings.
Round 1 dispositions: refuted stale/foreign dev-shell verification because this iteration is explicitly restricted to the two posted threads, the existing setup contract requires this checkout's dev shell, and the recorded approach already selects its absolute executable. Refuted removing base-build.log: the dedicated artifact isolates base diagnostics from the whole-run stderr and is the accepted feature; the posted finding specifically requests preserving successful pairing when its writer fails. The reviewer accepted both responses with no remaining findings. No source changes follow this reviewed head.
Follow-ups
The online macOS cwd finding was reproduced on Linux with a symlinked TMPDIR, then fixed by applying Pullfrog’s exact one-line suggestion. All nine launcher tests pass with the symlinked path.
No new quests. Gate performance stays with five-minutes, paired-comparison calibration with bench-ci, and broader performance/coverage work with audit-perf.
The host's Codex BASH_ENV snapshot reloads Nix environment variables in nested shells: CARLA's sim/python.test.sh fails on both this branch and unchanged origin/main with an inherited PYTHONPATH instead of the fixture's expected empty value. Recommended follow-up: repair the host snapshot loader so it preserves child-process environment overrides. No repository harness environment was cleared to obtain a pass.
Maintainer decision
Decided 2026-11-04 (/quest-unblock): ✅ hosted CI suffices for the strict Nix gate. Local check flake skipping on a host that refuses user-namespace mapping is expected since moq-dev/moq#7763. The strict check runs in hosted CI on the ready PR. Requiring a namespace-capable local builder was not chosen.
Preserve explicit host toolchains with visible build identity, and keep pinning details in the development guide.

fix(ci): pin quest commands and retain benchmark base errors
Nov 3, 2026
The change adds a Quest launcher that selects a pinned, host, or Nix executable, and routes repository gates and checks through it. It also captures Criterion base-build diagnostics in the benchmark evidence directory and adds integration tests for broken, existing, and new base targets. The related CI plan entry and investigation document are removed.
Merge Risk: Low · up to ff1dd
The changes have bounded tooling risks: failed log writes can suppress benchmark comparisons, and Windows contributors encounter a platform-incompatible test. Address these issues or explicitly accept them before merging.

No actionable findings. The change is appropriately scoped: base-build diagnostics are streamed and retained while pipefail preserves failed-build classification, and the launcher uses the dev shell's absolute quest executable without per-gate Nix evaluation. Explicit host-toolchain reporting remains clearly unverified. The surrounding admission paths, target discovery, cleanup, and regression-test routing look consistent. No change requested from this review.
Verification limits: GitHub-only static inspection of the implementation, callers, tests, and documented decisions. I did not run builds, tests, benchmark comparisons, or Nix/Windows workflows, and did not independently reproduce the reported local validation.

The new cwd-preservation test in sh/local.test.py compares os.getcwd() against an unresolved TemporaryDirectory path, so it fails on macOS where TMPDIR lives under the /var symlink. One-line fix inline.

Pinned quest launcher: sh/quest.sh uses the dev shell's absolute quest via MOQ_QUEST, reports host-toolchain builds against the flake.lock pin, and falls back to nix run .#quest; sh/local.sh, sh/dispatch.sh, flake.nix, README.md, and doc/setup/dev.md route through it.
Base-build diagnostics: bench/run.sh tees the base Criterion build into base-build.log, and the new bench/build.test.py covers broken, existing, and new base targets with real Cargo.
Fixtures and cleanup: dispatcher/fixture tests stub the pinned quest and copy quest.sh; sh/local.test.py adds pinned, host, and fallback cases; the completed quest and its README link are removed.

Give the PATH and pinned quest stubs different output.
The fixture writes one quest stub into self.bin, the only PATH entry. It also sets MOQ_QUEST to that same file. A dispatcher that runs quest check from PATH prints the same pinned quest check line, so this assertion still passes. Give the PATH stub distinct output. Point MOQ_QUEST at a separate pinned stub. Then assert that the host output is absent.
Apply the fixture's existing executable-permission step to both stubs.

Assert the base-build log on the successful existing-base path.
The existing-base case never reads base-build.log. The log is checked only in the broken-base case. A change that keeps base-build output only after a failed build would still pass this test.
Remove CARGO_TERM_QUIET from the test environment, so Cargo's status lines are not suppressed by the host. Then check the log in the success branch. The more specific "Compiling moq-relay" text is also less likely to match unrelated output than "moq-relay".

Reviewed the two commits since the prior pullfrog review (ff1dda969): the base-build failure split, its new test case, and the platform guard.
Separated log-write from build failures: bench/run.sh now captures PIPESTATUS into build_status, so a failing tee prints Failed to write base build log: while the successful base target list and paired comparison are retained; only a non-zero build status truncates criterion-base.targets and marks targets unavailable.
Added a log-failure base scenario: bench/build.test.py injects a tee stub that fails only for base-build.log, then asserts empty unavailable, a non-empty base target list, and the retained base catalog ran output.
Guarded the Nix fallback test: test_outside_shell_resolves_the_checkout_pin is skipped on win32/cygwin, where sh/quest.sh takes the host-toolchain branch.
I verified the PIPESTATUS-inside-|| capture under set -euo pipefail in bash, ran python3 bench/build.test.py (passes, including the new subtest), and ran the guarded launcher test (passes). The single prior pullfrog thread was already resolved by 69fd2f7; nothing else carried forward.

Problem
Benchmark comparisons reported a generic base-build failure without a dedicated build log, and repository gates could resolve a different quest from the build pinned by the checkout.
Approach
base-build.log. Keep the build status separate from the log writer so a failed log write does not discard a successful paired comparison.Impact
Alternatives and choices
Current main already builds the catalog base. The isolated worktree from moq-dev/moq#7445 stays unchanged.
A per-gate
nix runwas dropped after local review because it repeatedly evaluates and copies the checkout. An absolute executable supplied by the dev shell keeps the exact build cheaply.The quest Goal allows reporting which build ran, while its Plan describes failing on a mismatch. I preserved the existing explicit host-toolchain opt-out and report its build as unverified. Recommended clearer wording: “Explicit host toolchains report executable, version, and repository pin; build identity is unverified.” This avoids removing Windows/host support or claiming that the shared
0.1.0version identifies a source revision.Validation
2026-11-05 iteration: fixed the two CodeRabbit threads only.

The four real-Cargo base scenarios and all nine launcher tests also pass independently throughquest gate. The new log-write failure scenario retains the successful base target and comparison; the Nix-only launcher test skips Windows/Cygwin.Current unchanged base

All passed except the existing CARLA environment failure documented below and two fixture quote-format lines, subsequently fixed and verified by the passing scoped rerun.

All three real-Cargo base scenarios pass; the complete repository tooling suite passes.Current-main catalog comparison from the implementation round: nine unchanged cases, no unavailable targets, with a retained nonempty base-build log.
nix develop --accept-flake-config -c quest gate just ci origin/main: full repository scope. Rust's 11,690 tests pass. Final post-review run: every lane passed except strict local Nix (namespace refusal) and the reproduced base CARLA environment failure. JavaScript tests, C/C++, Kotlin, Go, Dart, Rust, and the complete tooling suite passed. Swift skipped on Linux by design.CHECK_MODULES=flake just check origin/main: succeeds withcheck flake (skipped)because this local Nix builder cannot create user namespaces, as expected under the maintainer decision below.CARLA's

Claude Code / Claude Opus 5.5, medium effort, session
c728ad5e-14ee-48c4-abfe-c3503a74bf9d, round 2 reviewed 2f9f857d040538d20a57e625d6853e4b09dc8980 againstorigin/mainatd0c73e35844c65bdd27bd43cba37431de14fee60: no findings.Round 1 dispositions: refuted stale/foreign dev-shell verification because this iteration is explicitly restricted to the two posted threads, the existing setup contract requires this checkout's dev shell, and the recorded approach already selects its absolute executable. Refuted removing
base-build.log: the dedicated artifact isolates base diagnostics from the whole-run stderr and is the accepted feature; the posted finding specifically requests preserving successful pairing when its writer fails. The reviewer accepted both responses with no remaining findings. No source changes follow this reviewed head.Follow-ups
The online macOS cwd finding was reproduced on Linux with a symlinked
TMPDIR, then fixed by applying Pullfrog’s exact one-line suggestion. All nine launcher tests pass with the symlinked path.No new quests. Gate performance stays with five-minutes, paired-comparison calibration with bench-ci, and broader performance/coverage work with audit-perf.
The host's Codex
BASH_ENVsnapshot reloads Nix environment variables in nested shells: CARLA'ssim/python.test.shfails on both this branch and unchangedorigin/mainwith an inheritedPYTHONPATHinstead of the fixture's expected empty value. Recommended follow-up: repair the host snapshot loader so it preserves child-process environment overrides. No repository harness environment was cleared to obtain a pass.Maintainer decision
Decided 2026-11-04 (/quest-unblock): ✅ hosted CI suffices for the strict Nix gate. Local
check flakeskipping on a host that refuses user-namespace mapping is expected since moq-dev/moq#7763. The strict check runs in hosted CI on the ready PR. Requiring a namespace-capable local builder was not chosen.Gate repairs moq-dev/moq#7654 and moq-dev/moq#7632 have landed and are included by merging
