…inning a model
A LazyCodex role with no root model pin but a pinned model_reasoning_effort could not
change or clear that effort: the dashboard Save needed a non-empty model draft and
PUT /api/codex-agent-roles/{role} required a model.
PUT now treats model as optional. An omitted model leaves the role file's pin (or its
absence) and the omo.jsonc model untouched; an omitted effort keeps the effort; a null
effort clears it. A null model stays 400 invalid_model and a body with neither key is
400 empty_update. The omo.jsonc mirror changes only reasoning for an effort-only save
and creates an absent entry only to hold one. The dashboard enables Save for an effort
change on a row without a pin, sends {effort} alone, keeps the mirror retry for set and
clear, and shows the effort next to the No model pin label. The commented-omo.jsonc
notice no longer tells users to set .model by hand.

optional chaining when checking whether body.model is undefined, consistent with

Mirror #6975's English role-models text in the fr, ja, ko, ru, tr, zh-cn and zh-tw guides: a row without a model pin can save an effort alone, omitting model keeps the role-file pin and the omo.jsonc model, a missing omo.jsonc entry gets reasoning only when a supported level is stored, a null model is refused with 400 invalid_model, an empty update with 400 empty_update, and ocx agent roles set always takes a model.

#6975's English said a role without an omo.jsonc entry always gets one holding only reasoning. writeOmoRoleModel only creates it when a level LazyCodex supports is saved (none is written as off); for such a role a clear or ultra adds no entry. The translations already say this. Co-authored-by: LilMGenius <smsmeee@naver.com>

… guides (#6976) Documents the effort-only role save from #6975 in the fr, ja, ko, ru, tr, zh-cn and zh-tw integrations guides: a row without a model pin can save an effort on its own, omitting model keeps the pins, a null model is refused with 400 invalid_model and an empty update with 400 empty_update, and ocx agent roles set always takes a model. The English guide's omo.jsonc sentence is narrowed to match writeOmoRoleModel: a role without an omo.jsonc entry gets a reasoning-only entry only when a LazyCodex-supported effort is saved, and for such a role a clear or ultra adds no entry.

Summary
A LazyCodex role that inherits its model (no root
modelpin) but pinsmodel_reasoning_effortcould not change or clear that effort. On the omo tab the row's model draft is empty, so picking Inherit effort or another level never enabled Save, andPUT /api/codex-agent-roles/{role}required amodelanyway. The only way out was to pin a model the user did not want. This resolves the open Codex review finding on #6960 (r4243110906).The PUT contract is now explicit:
modeleffort[codex].agents.<role>modelset,reasoningkeptnullmodelset,reasoningset / removedmodeluntouched,reasoningset; an absent entry gets{ "reasoning": ... }nullmodeluntouched,reasoningremoved; no entry is createdempty_update, neither file readnull/ non-string / emptyinvalid_model(a save never removes a model pin)The response echoes
modelonly when the request sent one, as it already did foreffort. LazyCodex declares bothmodelandreasoningoptional in its agent schema, so a reasoning-only entry is valid there.In the dashboard, a row without a model pin enables Save as soon as its effort changes and sends
{ "effort": ... }alone. The omo.jsonc mirror retry also works for those rows, including anullclear, through pending or failed reloads, and a later model pick or Auto-assign Apply still carries the outstanding effort. The Current column shows the effort next to No model pin. The success notice reuses the existing string with that label, so no locale keys were added. The commented-omo.jsonc notice no longer tells users to set[codex].agents.{role}.modelby hand, because for an effort-only save that would add a pin. It now names[codex].agents.{role}in all 11 locales.Existing clients are unchanged: a model-only PUT, Auto-assign Apply (model plus optional effort), and
ocx agent roles setall still send a model.English docs (
guides/integrations.md),structure/subagents.md, andstructure/clients/integrations.md(edited in place, still 599/600 lines) describe the new contract. Translated guides are handled separately.Screenshot (isolated CODEX_HOME;
