feat(codex): choose a cyber access program for Daybreak-eligible models - #27928
T3 omitted cyberAccessProgram from Codex app-server turns, which leaves the treatment to OpenAI's server and gives users no way to turn Daybreak off. Codex's own clients send Standard unless Daybreak is on.
T3 now does the same. Models in Codex's catalog offer a Cyber Access choice that defaults to Standard, or to Daybreak when Codex's daybreak setting is on, and the program goes out on every turn/start. Turns with no selection use the model's default from the provider snapshot. Custom models keep omitting the field, as Codex does for models missing from the catalog. The choice stays selected for new threads, matching Codex's /daybreak.
Full evidence on 5b6fdd1d7b, including frame logs, a recording and backend enforcement results: follow-up comment.
vp run check:changed passed: format, lint, both knip checks, GraphQL generation, typecheck for four packages, and six test files.
Real composer turns sent standard with nothing chosen (Luna, stored with no option), daybreakBlue after a reload, in a new thread that carried the choice, and on the Daybreak Blue model, then standard after choosing Standard and on 6.1-Sol.
With -c daybreak=true, Luna sent daybreakBlue and 6.1-Sol sent standard.
OpenAI rejects Standard on gpt-daybreak-blue-latest (400) and Daybreak Blue on gpt-6.1-sol (403), so the backend reads the field. A completed turn still doesn't report which program ran.

Walkthrough
Codex models can display configured Cyber Access choices. The adapter resolves a valid selected or default program and includes it in turn/start requests. Custom models with borrowed capabilities do not inherit the Cyber Access selector.

Summary
Configure model Cyber Access options apps/server/src/provider/CodexProvider.ts, apps/server/src/provider/CodexProvider.test.ts, docs/user/providers-codex.md
The provider maps advertised programs to choices and applies Daybreak and API-key configuration. Standard is the default when available; otherwise, the first advertised program is the default. Custom models with borrowed capabilities do not inherit the selector. Tests cover these behaviors. Documentation describes the choice and Daybreak sign-in guidance.
Resolve and forward the program apps/server/src/codexModelOptions.ts, apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.test.ts, packages/effect-codex-app-server/src/client.ts, apps/server/src/provider/Drivers/CodexDriver.ts, apps/server/src/provider/Drivers/CodexManagedProvider.ts
The adapter validates the selected program and model default. A valid explicit selection takes precedence; otherwise, the adapter uses a valid default or omits the field. The client accepts the optional field. Tests cover parameter selection and a completed replay turn.

The changeset adds a Cyber Access selector to Codex models that advertise cyber programs, and forwards the chosen program on every turn/start.

Full details: Description check
Explanation
The description follows the template's main sections. The Summary explains the problem (T3 omitted cyberAccessProgram) and the change. The Evidence section lists specific verification steps and results, and it names unverified areas. The Merge Danger section covers blast radius. The template's Problem, Change, and Scope and approval headings are not used as written. The Scope and approval requirement is only partly covered. The description links the original discussion (#26995) and a maintainer verification request, but it does not clearly state an explicit maintainer approval of scope. The description also links the approval comment only indirectly, through the reviewer's verification request. The Verification section gives concrete results and states what was not checked.
Resolution
Map the content to the template headings: add a Problem section and a Change section. In the Scope and approval section, link the triaged issue or discussion and include the maintainer approval comment that approves the direction and scope. Note that the feature is focused configuration of an existing capability and explain what that capability controls. Keep the Verification section as is. Replace the Summary and Merge Danger headings with the template structure, or state that these sections are added on top of the template.

Also, @JacksonBarker made a really good point - with the changes - there's no way to specifically turn off daybreak access with t3 currently, I believe it'll send auto instead of standard, which will let codex choose
verified the server/provider forwarding on Linux at 5492df89e135b279885f6d6c6681c6e6253fb829, without code changes. compared with github/main at 54c5f25249961a1aa0b61932329092eadbd9d6fc in a separate worktree. installed both with vp i and ran one background dev server at a time with isolated data.
used repo Playwright and /usr/bin/google-chrome to add the real git repository, create threads, submit real Codex gpt-6.1-sol turns, and inspect responses. no mocks, fixtures, demo provider, or invented catalog entries.
this proxy catalog returns availableAccessPrograms: null for every model. the Cyber Access selector therefore correctly stays hidden on Sol and Luna. to exercise the changed server path, sent explicit model options through the authenticated running servers WebSocket orchestration.dispatchCommand API, then observed the actual Codex app-server protocol log and the response in the web client.
short transcript, reduced from the real outbound turn/start frames:
daybreak forwarding also passed again after restarting the pr server. the neighboring normal-turn and follow-up flows returned the requested text, and Sol retained reasoning, service tier, and permission controls. filtered protocol transcript.
ran through blacksmith-check: vp i followed by vp test run apps/server/src/provider/CodexProvider.test.ts apps/server/src/orchestration-v2/Adapters/CodexAdapterV2.test.ts. both files passed, 131 tests. the current head also has 28 green CI results (20 passed, 8 skipped), zero failing or pending.
matching conversation crops below show the same response on main and the pr. these images alone do not prove forwarding; the protocol transcript above distinguishes them.
12-second recording of the pr response and a follow-up submitted with the real composer. inspected the exported clip and verified uploaded playback and seeking.
Not verified
inline video playback inside the GitHub comment: GitHub treats the externally hosted mp4 as an image. the uploaded video itself passed playback and seeking in the T3 browser player; the PNGs render correctly on GitHub. Cafe renders external media as links.
eligible-model selector, changing its selection, and persistence through reload: the real proxy catalog advertises no eligible models. the server API checks above do not substitute for this UI check.
actual Daybreak entitlement or backend program execution: the proxy completed the requests, but Codex supplies no completed-turn confirmation of the applied program. this proves T3 forwarding, not that the upstream ran Daybreak.
native iOS/Android, Electron-specific behavior, macOS/Windows, remote/relay/tunnel connections, custom-model UI, and Codex-native subagent inheritance were not exercised on this Linux VM.
no source changes or pushes were needed. no merge, close, rebase, force-push, or label changes.

@maria-rcks I ran your open checks on an account with Daybreak Blue, at 5492df89e1 on macOS with Codex CLI 0.165.0. The selector and its persistence work, and OpenAI's backend does act on the field.

Screenshots, in table order, taken at 1920x1200 and saved at 1280x800. The thread behind each menu holds four earlier "reply ok" turns on the same commit.
Real composer turns. A logging wrapper around codex recorded these outbound turn/start frames. All four turns completed.

gpt-6-luna Standard -> cyberAccessProgram standard
gpt-6-luna Daybreak Blue (after reload) -> cyberAccessProgram daybreakBlue
gpt-6.1-sol switched from Luna on Blue -> cyberAccessProgram omitted
The last line shows the Blue selection doesn't carry over to a model that doesn't offer it. Sending it there would get a 403, as the next section shows.
A recording of these four turns, plus the Sol, Daybreak Blue and custom-model menus, in one take at 3360x2100. It came from a later run on the same commit, using Playwright with Chrome at 2x because the T3 browser panel's captures were blurry. The logged frames for that run match the block above.
live-turns-sharp.mp4
Backend enforcement. I sent these directly to codex app-server on the same login, using ephemeral threads.
gpt-daybreak-blue-latest standard -> 400 "The Daybreak Blue model requires access_programs.cyber=daybreak_blue."
gpt-daybreak-blue-latest omitted -> completed
gpt-daybreak-blue-latest daybreakBlue -> completed
gpt-6.1-sol daybreakBlue -> 403 "Daybreak isn't available for this model. Turn off Daybreak or choose another model."
gpt-6.1-sol standard -> completed
The two rejections show OpenAI reads the program. A completed turn still doesn't report which program ran, so I can't confirm that from the Luna turns. Because Standard is rejected on the Blue model and omission isn't, omission there can't mean Standard.
What omission does on the wire. I ran the real app-server against a local mock Responses API with a dummy API key.
-c daybreak=false gave the same results. So main sends no program at all, and OpenAI's server decides. cyber_access_program.rs forwards the same value for ChatGPT sign-in, but I only read that path and didn't run it against the mock.
The Automatic default differs from the CLI.daybreak defaults to false in Codex config. With it off, Codex's TUI and exec send explicit standard for eligible accounts when the model advertises it (tui/src/daybreak.rs, exec/src/daybreak.rs). So the PR's Automatic matches app-server omission, not the CLI's default. This is the gap Jackson raised, and it's why #27835 asks for an explicit opt-out. Standard-only and custom models also have no selector, so T3 can't send standard for them.
The selection carries into new threads. After I picked Daybreak Blue on Luna in one thread, a new thread's composer opened on Luna with Daybreak Blue already selected. The docs in this PR say the choice applies "in that thread". I set Automatic before sending, so I didn't test a turn from that state.

🤖 Claude Opus 5.5 responding on behalf of Martin Meredith
@maria-rcks I pushed 5b6fdd1d7b (rebased onto current main, with the captures and turns below redone on it), which replaces Automatic with Codex's default, so this replaces the evidence in my earlier comment wherever the two differ. T3 now sends Standard unless the user picks Daybreak or sets daybreak = true.
What changed
A model in Codex's catalog now defaults to Standard when it offers it. With daybreak = true, it defaults to Daybreak when it offers that. This matches tui/src/daybreak.rs and exec/src/daybreak.rs.
Automatic is gone. Standard-only and Daybreak-only models show a one-option selector, so the program being sent is visible.
Turns with no selection use the model's default from the provider snapshot, with no extra app-server requests.
Custom models still omit the field, as Codex does for models missing from the catalog.
The carry-over into new threads stays, because Codex's /daybreak also saves the choice for new threads (tui/src/app/daybreak.rs). The docs now say so instead of "in that thread".
I couldn't read OpenAI's help articles, which return 403 to my tools, so this follows Codex's source and the guidance quoted in #27835.
One deliberate difference from Codex. With Daybreak on and a model that doesn't offer it, Codex stops with an error and T3 stays on Standard, so an existing daybreak = true config doesn't break every Sol turn.
Recording. The full flow in one take on 5b6fdd1d7b, 3360x2100, from a fresh browser profile. I used Playwright with Chrome at 2x because the T3 browser panel's captures were blurry.

Real composer turns on that take. A logging wrapper around codex recorded these outbound turn/start frames. All six turns completed.
gpt-6-luna nothing chosen -> standard
gpt-6-luna Daybreak Blue, after a reload -> daybreakBlue
gpt-6-luna new thread, carried over -> daybreakBlue
gpt-6-luna Standard chosen -> standard
gpt-6.1-sol switched from Luna -> standard
gpt-daybreak-blue-latest switched from Sol -> daybreakBlue
The first turn is stored with no cyber option on the run, so it exercised the snapshot fallback.
With -c daybreak=true in the provider's launch arguments, from another fresh profile. Both turns completed.
gpt-6-luna nothing chosen -> daybreakBlue
gpt-6.1-sol no Daybreak -> standard
This gives #27835 its separate on and off providers.

A completed turn still doesn't report which program ran, so T3's forwarding and these rejections are provable, but what ran on a completed turn isn't.
Local checks and review.vp run check:changed passed on the rebased commit. GPT-6.1-Sol approved after 2 review rounds. Its one finding was that a saved explicit program still reaches Codex in an API-key session with features.api_key_cyber_access_programs = false. We kept that, because Codex then rejects the turn visibly, which is what #27835 asks for. CodeRabbit raised the same point for stale selections, and I dismissed it with the same reason on its thread.

Codex's app server only applies Daybreak when each turn/start carries
cyberAccessProgram; its config.toml `daybreak` setting does not reach
app-server turns. T3 never sent the field, and the turn/start encode
schema dropped it.
Models whose catalog entry lists a Daybreak program in
availableAccessPrograms.cyber now get a Cyber Access select. Its default,
Automatic, omits the field so Codex keeps its own behaviour.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A bare custom Codex slug borrows the first built-in model's options, so it
could show Cyber Access even though Daybreak eligibility is per model.
Strip that option from borrowed capabilities, type the turn/start field
with the turn/start schema, and document the setting.

Omitting cyberAccessProgram leaves the choice to OpenAI's server, while
Codex's own clients send Standard unless Daybreak is on. Models in the
catalog now default to Standard, or to Daybreak when Codex's daybreak
setting is on, and T3 sends the program on every turn. Turns with no
selection use the model's default from the provider snapshot.
