Branch: warden/issue-1159-codex-rust-cli-policy | 4 files, +69/-13 | CI: Bridge TypeScript pass 15s https://github.com/Q00/ouroboros/actions/runs/26224043515/job/77166237294
Scope: diff-only
HEAD checked: 7c4f5b5f5e337c4a04344f434c6689ea75397a05
What Improved
- Tightened Codex wrapper detection so Mach-O/ELF magic alone no longer causes official Rust Codex binaries to be treated as wrappers.
- Updated both runtime/provider wrapper fallback tests and verified the focused pytest suite passes with
SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0.
Issue #1159 Requirements
| Requirement | Status |
|---|---|
is_wrapper_binary() returns False for OpenAI Codex CLI v0.132+ on macOS/Linux |
NOT MET — Mach-O is tested, but Linux/ELF official Rust binary behavior is untested |
ouroboros run workflow seed.yaml --dry-run no longer emits wrapper/fallback warnings for system codex |
MET — shared resolver now returns no wrapper warning when the PATH codex is an official Rust Mach-O sample |
Regression test covers the official Codex CLI Rust binary in tests/unit/codex/ |
PARTIAL — present for Mach-O only |
Prior Findings Status
| Prior Finding | Status |
|---|---|
| No prior in-scope blocker was raised; previous review could not inspect source/diff | MAINTAINED — no stale blocker was carried forward; current review re-verified the checked-out HEAD and diff |
Blockers
| # | File:Line | Severity | Confidence | Finding |
|---|---|---|---|---|
| 1 | tests/unit/codex/test_cli_policy.py:43 |
Medium | 90% | Issue #1159 explicitly requires is_wrapper_binary() to return False for OpenAI Codex CLI v0.132+ on macOS/Linux, and the implementation changes ELF behavior via src/ouroboros/codex/cli_policy.py:17, but the new official-Rust regression only constructs a Mach-O sample. The Linux/ELF acceptance path is therefore not covered by the required regression tests. |
Follow-ups
| # | File:Line | Priority | Confidence | Suggestion |
|---|
Test Coverage
Focused tests pass: 99 passed for tests/unit/codex/test_cli_policy.py, tests/unit/orchestrator/test_codex_cli_runtime.py, and tests/unit/providers/test_codex_cli_adapter.py. Ruff also passes for changed files. Coverage is not complete for the linked issue because the official Rust binary regression only covers Mach-O, while the changed classifier also includes ELF/Linux behavior.
Design / Roadmap Gate
The PR aligns with the design-gate direction in design_context.md: fix the focused Codex Rust CLI compatibility bug without broad runtime redesign. The remaining gap is traceability to the Linux half of the stated issue acceptance criteria.
Merge Recommendation
- Merge after adding an ELF/Linux official Rust Codex regression test for the changed classifier/resolution path.

Scope: diff-only
HEAD checked: 7c4f5b5f5e337c4a04344f434c6689ea75397a05
What Improved
- Wrapper detection now requires a compiled-binary header plus a wrapper-specific signature, so Mach-O official Rust Codex samples are no longer treated as wrappers.
- Runtime and provider fallback tests were updated to keep known wrapper fallback behavior intact with the new signature requirement.
Issue #1159 Requirements
| Requirement | Status |
|---|---|
is_wrapper_binary() returns False for OpenAI Codex CLI v0.132+ on macOS/Linux |
PARTIAL — current logic should accept official binaries without wrapper signatures, but only the macOS/Mach-O sample is covered by regression tests. |
ouroboros run workflow seed.yaml --dry-run no longer emits cli_wrapper_detected / cli_no_fallback for system codex |
PARTIAL — shared resolver has a no-warning Mach-O PATH test at tests/unit/codex/test_cli_policy.py:56; the Linux/ELF system-codex path is untested. |
Regression test covers the official Codex CLI Rust binary in tests/unit/codex/ |
PARTIAL — official Rust coverage exists for Mach-O only, not Linux/ELF. |
Prior Findings Status
| Prior Finding | Status |
|---|---|
| Missing ELF/Linux official Rust Codex regression coverage for issue #1159 | MAINTAINED — current HEAD still only synthesizes Mach-O official Rust samples in tests/unit/codex/test_cli_policy.py:43 and tests/unit/codex/test_cli_policy.py:61; no \x7fELF official Rust acceptance test is present. |
Blockers
| # | File:Line | Severity | Confidence | Finding |

| 1 | tests/unit/codex/test_cli_policy.py:43 |
Medium | 95% | Issue #1159 requires is_wrapper_binary() to return False for official Rust Codex v0.132+ on macOS/Linux, and the implementation explicitly changes ELF classification in src/ouroboros/codex/cli_policy.py:17, but the regression suite only constructs Mach-O official Rust samples at lines 43 and 61. The Linux/ELF acceptance path introduced by this PR is still untested, so the issue’s platform-specific acceptance criteria are not fully covered. |

Test Coverage
Focused tests pass: SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0 uv run pytest tests/unit/codex/test_cli_policy.py tests/unit/orchestrator/test_codex_cli_runtime.py tests/unit/providers/test_codex_cli_adapter.py -q reported 99 passed. Coverage is still incomplete for newly added classifier behavior: src/ouroboros/codex/cli_policy.py:14-17 includes ELF as a compiled binary header, but tests/unit/codex/test_cli_policy.py:40-76 only verifies official Rust Codex behavior with Mach-O bytes.
Design / Roadmap Gate
The PR aligns with the focused design-gate direction in design_context.md: fix the Codex Rust CLI compatibility bug without broad runtime redesign. The remaining gate issue is traceability to the Linux half of the stated issue acceptance criteria, because current HEAD changes ELF behavior in src/ouroboros/codex/cli_policy.py:17 without a matching ELF regression.
Merge Recommendation
- Merge after adding an ELF/Linux official Rust Codex regression test for
is_wrapper_binary()and preferably the resolver no-warning path.

Add the missing ELF regression coverage that the bot identified so the Rust Codex CLI policy proves both macOS and Linux acceptance paths without expanding runtime scope.\n\nConstraint: PR #1162 must stay a focused Codex CLI compatibility fix outside AgentOS Track C tier gates.\nRejected: Broader AgentOS or runtime redesign | #961 keeps roadmap work in narrow child slices, and this PR only closes #1159.\nConfidence: high\nScope-risk: narrow\nDirective: Keep wrapper detection signature-based; do not reintroduce magic-header-only rejection for native Codex binaries.\nTested: SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0 uv run pytest tests/unit/codex/test_cli_policy.py tests/unit/orchestrator/test_codex_cli_runtime.py tests/unit/providers/test_codex_cli_adapter.py -q; uv run ruff check src/ouroboros/codex/cli_policy.py tests/unit/codex/test_cli_policy.py tests/unit/orchestrator/test_codex_cli_runtime.py tests/unit/providers/test_codex_cli_adapter.py\nNot-tested: Full repository test suite
Format the ELF regression tests with the repository Ruff formatter so CI can verify the focused compatibility fix.\n\nConstraint: CI runs ruff format --check across src/ and tests/.\nRejected: Amending the pushed coverage commit | keeping a small follow-up preserves bot review traceability.\nConfidence: high\nScope-risk: narrow\nDirective: Run both Ruff check and Ruff format check for changed Python tests before pushing follow-ups.\nTested: SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0 uv run pytest tests/unit/codex/test_cli_policy.py tests/unit/orchestrator/test_codex_cli_runtime.py tests/unit/providers/test_codex_cli_adapter.py -q; uv run ruff check src/ouroboros/codex/cli_policy.py tests/unit/codex/test_cli_policy.py tests/unit/orchestrator/test_codex_cli_runtime.py tests/unit/providers/test_codex_cli_adapter.py; uv run ruff format --check tests/unit/codex/test_cli_policy.py\nNot-tested: Full repository test suite
Create a no-op review trigger because PR #1162 is green after the ELF coverage and formatting follow-ups, but the latest bot review still references the pre-fix commit. Constraint: User requested an empty commit if bot reaction is absent after pushing fixes. Rejected: Proceeding to final comments before bot approval | workflow requires ouroboros bot approval/design-note clearance first. Confidence: high Scope-risk: narrow Directive: Do not treat this no-op as behavior change; review the prior coverage commits for substance. Tested: GitHub checks on c11c651 are green; local focused pytest/Ruff checks passed before push. Not-tested: No new code in this commit Co-authored-by: OmX <omx@oh-my-codex.dev>

@ouroboros-agent Re-review requested for latest HEAD b85c5b5. The prior blocker was addressed with ELF/Linux official Rust Codex regression coverage for both is_wrapper_binary() and resolve_codex_cli_path(), and all GitHub checks are green. |

Re review ping |
Name the Linux/ELF Rust Codex classifier and resolver regressions directly so the review gate can trace the exact #1159 acceptance criterion.\n\nConstraint: ouroboros-agent's blocking finding is tied to explicit macOS/Linux coverage traceability.\nRejected: Broadening implementation logic | the policy already has the correct signature gate; only test traceability needed tightening.\nConfidence: high\nScope-risk: narrow\nDirective: Keep #1162 focused on #1159 compatibility; do not fold AgentOS Track C work into this branch.\nTested: SETUPTOOLS_SCM_PRETEND_VERSION=0.0.0 uv run pytest tests/unit/codex/test_cli_policy.py tests/unit/orchestrator/test_codex_cli_runtime.py tests/unit/providers/test_codex_cli_adapter.py -q; uv run ruff check src/ouroboros/codex/cli_policy.py tests/unit/codex/test_cli_policy.py tests/unit/orchestrator/test_codex_cli_runtime.py tests/unit/providers/test_codex_cli_adapter.py; uv run ruff format --check tests/unit/codex/test_cli_policy.py\nNot-tested: Full repository test suite

What Improved
- Refines Codex CLI wrapper detection so official native Rust Mach-O/ELF binaries are no longer rejected solely because they are compiled binaries.
- Adds regression coverage for official Rust Codex binaries and known compiled wrapper fallback behavior.
Issue Requirements
| Requirement | Status |
|---|---|
| No linked issue requirement captured | N/A |
Prior Findings Status
Prior blocker appears addressed: PR comments state the previous concern was missing ELF/Linux official Rust Codex regression coverage, and the current diff adds both direct is_wrapper_binary() and resolver coverage for Mach-O and ELF native binaries.
Blockers
No in-scope blocking findings remained after policy filtering.

Test Coverage Notes
- Reviewed changed tests in
tests/unit/codex/test_cli_policy.py,tests/unit/orchestrator/test_codex_cli_runtime.py, andtests/unit/providers/test_codex_cli_adapter.py. - Attempted focused test run, but this environment lacks
uv,python, andpytestforpython3.
Design Notes
The change keeps wrapper detection centralized in src/ouroboros/codex/cli_policy.py and preserves the existing runtime/provider adapter boundary.
Design / Roadmap Gate
Affected boundary is Codex CLI path resolution before subprocess execution. The new policy narrows wrapper classification from “any compiled Mach-O/ELF” to “compiled binary with known wrapper marker,” preserving fallback behavior for known wrappers while allowing official native Codex binaries to execute directly. No persistence, replay, or public API compatibility issue found.
Directional Notes
Review focused on the shared CLI resolution contract because this helper is used by both the orchestrator runtime and provider adapter. Maintainer memory was advisory only; no blocker was found from current HEAD evidence.
Test Coverage
- Reviewed changed tests in
tests/unit/codex/test_cli_policy.py,tests/unit/orchestrator/test_codex_cli_runtime.py, andtests/unit/providers/test_codex_cli_adapter.py. - Attempted focused test run, but this environment lacks
uv,python, andpytestforpython3.
Merge Recommendation
Approve. I found no current-HEAD blocking issues in the changed code or impacted call paths.

This replaces the stale design-blocked assessment with a focused compatibility fix: the Codex CLI policy files are present on current
main, so the reported bug is directly actionable.
