Codex stores a session's instruction block once and replays it verbatim into a sub-agent spawned on a DIFFERENT model, so a worker inherited the parent's identity sentence and answered identity questions with the parent's model id (lidge-jun#5217). Two halves, matching the issue's analysis: - The catalog no longer bakes a model id into `base_instructions`; a stored block that travels to another model cannot carry one honestly. It emits the model-neutral line instead. - The destination id is written at request time, where it is known: the parser repairs a developer item, and the Responses passthrough repairs the raw body — rewritten to the destination on a routed provider, dropped on a native/forward one, where Codex's own wording in the client's model_switch block is correct. Only the sentence this proxy generated is matched, anchored on its exact wording with the same model-id character class `safeRoutedModelIdentity` allows. User turns, tool output, fenced code and provider-native identity blocks are untouched. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Do not rewrite identity text inside fenced code.
repairRoutedIdentity and stripRoutedIdentity apply ROUTED_IDENTITY_RE to the complete developer or system text. An exact proxy-generated sentence inside a fenced code block therefore gets rewritten or removed. Split fenced and prose regions before matching, and apply identity repair only to prose.
Also require the same model identifier in both positions. The current alternatives match each identifier independently, so a non-emitted sentence with different model names can match.

Reviewed for the 260923 bundle round (lane E, #5675) and not carried. The review found that this change still leaves both directions of #5217 wrong (the worker can keep the parent's identity sentence, and a sub-agent's own identity can be replaced where it should stay), and that it can rewrite an identity sentence inside a fenced block. The fix needs a design for where the worker's own model identity comes from before it can land. Leaving this open. |

After #5221 the catalog stores the model-neutral identity line, so a native worker spawned from a routed parent received "Do not claim to be GPT-5 or to be made by OpenAI", contradicting Codex's own model_switch identity. The forward strip now removes the neutral line as well as a routed sentence; an instructions value that becomes empty is still removed.

Two review findings on the #5221 carry. The request parser names the identity sentence from the client selector, which can be an alias, a namespaced slug or a combo name, and adapters that never call identifyRoutedModel (devin, ollama-native, cursor, qoder, codebuddy, coding-agent) shipped that name. The final route normalization now renames our sentence to route.modelId, where the dispatched id is known and every dispatch path reads the context afterwards. The parser also names system-role input items, not only developer items. Co-authored-by: sbc1-code <207095575+sbc1-code@users.noreply.github.com>

…, sub-agent identity, agent-message recovery, 98% main lock (#5743) * docs(devlog): plan lane L4 Codex integration, CLI and service bundle * fix(service): preserve connected client key on uninstall (#5713) ocx service uninstall unconditionally deleted service-api-token, which on a remote-hub client is the per-client data-plane key issued by the hub (#5699). Uninstall now deletes the token only under the client lifecycle and config mutation locks, and only when persisted client state is disconnected and no pending connect marker owns the current key's fingerprint. Connect publishes that fingerprint marker before writing the key and clears it on commit or rollback. Lock, state-read and unlink failures report cleanup as unverified. On top of #5713: rollback checks the pending marker against its own fingerprint, so a valid marker for a different key is left alone instead of adding a spurious rollback failure. Carries #5713. Closes #5699. Co-authored-by: 정우철 <oocheol@naver.com> * fix(codex): bound aggregate rollout inspection during startup (#5703) The native-residue classifier limited each referenced rollout to 64 MiB but not the total, so the read-only startup preflight could parse gigabytes of conversation history on every Codex launch (#5701). One observation now reads at most 64 MiB of rollout content across the history database and backup manifest together; a file that would exceed the remaining budget is reported indeterminate before it is read, and classification stops at the first indeterminate surface. Exhausting the budget never reports clean. Carries #5703. Closes #5701. Co-authored-by: Konstantinos <37538071+konstantinosbotonakis@users.noreply.github.com> * fix(codex-home): import path expansion without the config facade (#5548) src/codex/home.ts imported expandUserPath from the ../config barrel, which re-enters the config facade before the Codex home resolver has initialized. On a fresh WSL process that import cycle could fail before the home was resolved. The resolver now imports expandUserPath from src/config/paths.ts directly, and a fresh-process regression test loads the resolver first with a tilde CODEX_HOME. Only the import fix, its structure note and the fresh-process test are carried; the PR's cli-help, service and docker expectation edits target the documented container-only failures and stay out.

Recovery and the unreadable-ciphertext guard now recognise all four codex-rs agent-message types, including a FINAL_ANSWER without a Task name line. Sender and admission checks are unchanged: credential admission still runs before any cache access, the structured author must equal the header sender, and the recipient is cross-checked whenever the header names one. The cache key is a JSON-encoded fixed-order tuple that binds the structured recipient, and a recovered assignment that echoes the other routing family is rejected. agentTaskRecovery stays default-off.

Co-authored-by: Zhaofeng Li <lzfxxx@gmail.com> * feat(codex): lock the main account at 98% by default (#5694) Codex Desktop disables its send button once the ChatGPT account window reads 0% remaining, even when the user routes every request to another provider. The main-account hard lock already stops ocx from admitting new identity-matched main-account requests at a usage threshold, but it was opt-in at 99%. The lock is now on by default at 98%: an absent or true codexMainAccountHardLock enables it, and only an explicit false opts out. Every gate reads one resolver (isMainAccountHardLockEnabled); the settings route persists false and deletes the key for true, like fastRows; a malformed hand edit falls back to the default; the blocked-request message derives its percent from the constant. Trade-offs: while blocked, the main account's Luna Reserve cannot activate; switching the setting off lets the main account run to exhaustion. The old switch deleted the key when turned off, so an earlier opt-out now reads as on and has to be switched off once more. GUI copy (all locales), the English and Korean accounts reference, and structure/providers/openai-tiers.md describe the new default. Refs #5694. * docs(devlog): record L4 publish plan * test(gui): expect the 98% hard-lock blocked label The main-card blocked label follows the #5694 threshold change. * fix(identity): drop the neutral catalog line on native destinations After #5221 the catalog stores the model-neutral identity line, so a native worker spawned from a routed parent received "Do not claim to be GPT-5 or to be made by OpenAI", contradicting Codex's own model_switch identity.

Fixes #5217.
The bug
Codex stores a session's instruction block once and replays it verbatim into a sub-agent spawned on a different model, so a worker inherits the parent's identity sentence. A worker actually running
gpt-6-astraanswersgpt-6because both sentences are in its prompt. Routing itself is correct; only the prompt text is stale.One detail worth flagging beyond the issue's analysis: the stale sentence does not arrive in
instructions. Codex sends it as adeveloperinput item, whichopenai-chatfolds into its system message (soidentifyRoutedModelsees it) but anthropic/google/kiro pass through as an ordinary message, and the Responses passthrough forwards untouched. That is why the repair could not live in the adapters alone.The change
Both halves the issue describes:
derive-entry.tsandmetadata.tsstop baking a model id intobase_instructions. A stored block that can travel to another model cannot carry one honestly.parseRequestrepairs adeveloperitem, and the Responses passthrough repairs the raw body — rewritten to the destination on a routed provider, dropped on a native/forward one, where Codex's own wording in the client'smodel_switchblock is the correct identity.Only the sentence this proxy generated is matched. The pattern is anchored on its exact wording and uses the same model-id character class
