Reviewed the native ingress, normalizePinnedChatEffort, and the previously outstanding shared effort-policy.ts admission/ladder path on this exact head. The base really did place the cap inside the pin branch, so unpinned eligible native Chat could bypass the configured ceiling.
The patch applies pin-before-cap, preserves v1/compaction exemptions, leaves absent/unranked/lower effort unchanged when no rewrite is needed, and restores the original effort for a new destination while same-destination retries retain their annotation. The new wire assertions cover both child markers, v2 main, omission, equal-valued pin mapping, and destination changes. I found no source-level blocker in that focused path.
This is not merge approval: full author CI 34358947830 was still running at inspection, and I did not execute product code locally. Keep the Draft/readiness gates pending exact-head completion and resolution of applicable review findings; no broad provider effort remapping is warranted by this fix.

Rechecked head 7bfc68c against current dev c15a98c, including the shared effort admission/capping helpers and native-chat snapshot path.
The cap now runs independently of pin resolution, while the existing v1 and compaction exemptions remain. Unpinned, unqualified caller spelling is preserved; pin application or an actual cap rewrite enters provider wire mapping. The retry regression observes the outgoing low/low/high values and annotations for one reused body across first/first/second destinations, so it checks the original-effort snapshot rather than merely a helper return.
Author CI run 34425539855 is independently verified successful at this exact head. I found no additional blocker in this scoped change. This is not a waiver of repository CI or the still-open Draft/readiness checklist; please finish those before final integration. No local product code, configuration changes, or live-provider probes were executed for this review.

| Configured effort caps apply to eligible native Chat Completions turns even without a model effort pin. Qualifying v2 main turns use `effortCap`; marked spawned-child turns use the lower applicable main/child ceiling. Explicit `multiAgentMode: "v1"` and compaction maintenance bypass caps. A cap only lowers or omits explicit effort, and provider wire mapping runs when a pin is applied or a cap changes the value. Native caller values retain their original wire spelling when no pin is applied and no cap rewrite occurs. |

This adds a second copy of the cap eligibility, exemption, and lowering rules even though this page's existing ## Effort caps section already owns those rules at lines 246–256, and the duplication is repeated across the translated pages. Maintaining the policy in two separated paragraphs makes future behavior updates likely to leave the copies contradictory; move the new native Chat pin/wire-mapping detail into the existing effort-cap section instead of restating the surrounding policy here.

The new paragraph restated cap eligibility, exemptions, and the lowering rule that the existing effort-cap section already owns, and the duplication was repeated across every translated page. Keep only the new native Chat Completions and wire-mapping detail, and move it into that section so the policy has a single home.
dev restructured structure/ and deleted 03_catalog-and-subagents.md, so the effort-cap SOT paragraph now lives in structure/catalog.md next to the existing pin/cap ordering rules.

This changes the src/server/ effort-cap contract, but the commit updates only structure/catalog.md; structure/INDEX.md maps this area to additional documents such as structure/subagents.md and structure/data-planes/inbound-compat.md.

Fresh evidence in the current tree is that this inserted paragraph now sits between “see” and its [Sub-agent surfaces] object, so the rendered English documentation reads as though readers should “see Configured caps…” and leaves the link as a detached paragraph; the Russian and Turkish edits split their link sentences similarly. Move the new paragraph before the complete cross-reference sentence.

Move the new paragraph after the complete sub-agent-surface reference in all affected locales.
The English and Russian paragraphs interrupt the preceding sentence, which ends with “see” or “см.” before the link. The Turkish paragraph is inserted inside the [Alt ajan yüzeyleri] link span. Move the paragraph after the complete reference in all three files so the sentence and link render correctly.

The cap paragraph was inserted before the line holding the link, which lands inside the sentence when that sentence wraps: English and Russian broke after "see"/"см.", and Turkish split the [Alt ajan yüzeyleri] link span itself. Place the paragraph before the whole sentence, matching the five locales whose reference fits on one line.

Summary
A native Chat Completions request could send
reasoning_effort: "ultra"despitesubagentEffortCap: "low"when no model effort pin was configured. Theopenai-chatkey/local fast path checked the cap only inside its pin branch, before returning without entering the Responses enforcement path.Apply the existing cap admission independently of pin resolution. Qualifying v2 main turns and marked spawned-child turns now honor their configured ceilings. Forced v1 and compaction remain exempt. Values below the ceiling, unranked values and absent effort retain their existing behavior. Provider wire mapping runs when a pin is applied (including an equal-valued pin) or a cap rewrites the value; otherwise caller spelling is preserved. Same-destination retries retain their prior decision and annotation, while a new destination recomputes from the original effort.
This updates the previous test and architecture statement that exempted all unpinned native Chat requests, to align that path with the documented hard-ceiling contract. The runtime change is confined to one normalization function. The public configuration reference is synchronized in eight locales.
