ApprovabilityVerdict: Needs Human Approval Macroscope's review found this PR requires human approval — Automatic workspace-write turns now inherit configured network access, writable roots, and temporary-directory settings when no explicit sandbox policy is provided. Human review is needed to confirm this change to effective default permissions is intended. You can add or adjust custom eligibility rules. Learn more. |

…of upstream pingdotgg#18344 at 087065f) Newer commits of pingdotgg#18344 than the copy adopted on 2026-10-11 (9b1502a). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Auto and Auto-accept-edits turns sent a bare workspaceWrite sandbox policy, which reset network access, writable roots and the tmp exclusions that Codex resolved from config. Read sandbox_workspace_write with config/read before those turns and carry its fields into the turn policy, falling back to the bare policy if the read fails.
…ion profiles Codex ignores [sandbox_workspace_write] when managed requirements set allowed_permission_profiles, but config/read still returns the table. Read configRequirements/read when a table exists and keep the bare workspaceWrite policy if profiles are managed or the read fails.
…ons selects a profile T3 starts Codex threads without a sandbox mode, so with default_permissions set Codex runs the thread under that permission profile and ignores [sandbox_workspace_write]. Copying the table into the turn policy granted network access and writable roots that the profile excludes. Keep the bare workspaceWrite policy when config/read returns default_permissions, and skip configRequirements/read in that case.

Taking over this one as maintainer for batch codex-07. I will preserve your commits, bring the branch up to current main, simplify the implementation and tests, and verify effective configuration, permission profiles, and runtime mode changes against a real Codex app server. I will push the result here for review; nothing will be merged. Thanks for the detailed probes and upstream analysis. |

Auto and Auto-accept-edits turns replace Codex’s configured workspace-write policy with a bare one, losing network access and temporary-directory exclusions. Fixes #13987.
Read Codex’s effective config for the runtime cwd before each default workspace-write turn, preserving its network access, writable roots, and both temporary-directory exclusions. Keep sending the policy each turn so mode changes apply immediately. Explicit sandbox policies, Full access, and approval-required turns make no lookup. Selected or managed permission profiles keep the previous bare policy; absent tables and selected defaults skip the requirements read. Both reads share a five-second deadline, with warning and bare-policy fallback on failure or malformed replies. This fallback retains main’s behavior, including default temporary-directory access.
Maintainer takeover of @gabrielrojasc’s implementation, preserving the original commits and @JonasFocus’s effective-config approach. Removed one-use helpers and lengthy implementation commentary.
Validation: 175 adapter tests and five scoped caller/replay tests pass, plus targeted lint/formatting and server typecheck. Six completed turns through the actual adapter and Codex 0.163.0 on Linux verified user/project/launch precedence, relative-root resolution, fresh config, mode changes, selected-profile exclusion, and saved native turn policies. Additional replay probes verified a hung config read, malformed requirements, and one deadline across both reads. The committed regression coverage was reduced from nine cases to six.
No model command or network enforcement was tested. Managed requirements use replay/source proof; Windows, macOS, mobile/Electron UI, and older supported CLIs (including the managed 0.156.1) were not run live; compatibility with 0.156.1 was checked against upstream source. Non-null default profile selection conservatively keeps the bare policy even if another layer’s sandbox mode would select the legacy table.
Implementation: GPT-6.1 Sol (high), Codex harness through T3 Code. Test minimization: GPT-6 Astra (high), Codex harness through T3 Code.
Independent whole-PR reviews: Claude Opus 5.5 and GPT-6 Sol found no blockers at this head.
Fixes #13987
