Conversation
Expand default shadow source models from gpt-5.6-luna only to the full ChatGPT-native lineup: gpt-5.6-luna, gpt-5.6-sol, gpt-5.6-terra, gpt-5.5, and gpt-5.4-mini. Each source model can now route to a different third-party replacement via shadowCallIntercept.modelMap. Design (Plan B): modelMap is the first-class per-source mapping; the existing shared model field remains as a fallback for source prefixes absent from the map. A source with no entry in either is left native (not intercepted), so operators can intercept luna and sol while leaving terra native. Changes: - src/lib/shadow-call.ts: expanded defaults; new shadowCallReplacementFor() resolves a source prefix to its modelMap entry, falling back to model. - src/types/config.ts: shadowCallIntercept.modelMap optional field. - src/server/responses/core.ts: route point uses shadowCallReplacementFor; no replacement => source left native. - src/server/management/config-routes.ts: GET/PUT /api/shadow-call-settings read/write modelMap; validates every replacement target. - src/server/management/shadow-call-validation.ts: shadowCallModelMapErrors checks each modelMap target does not intersect its own source. - src/providers/openai-tiers.ts: legacy migration + path allowlist cover modelMap values. - src/providers/provider-id-rewrite.ts: provider rewrite handles modelMap. - GUI: Models.tsx renders a per-source replacement dropdown row for each source model when shadow-call is enabled; ShadowCallData carries modelMap. - tests: updated defaults assertions; added Plan B mapping test suite.
Replace the shared fallback dropdown with user-defined custom mappings: an operator can type any source model id and map it to a replacement, not just the five built-in ChatGPT-native slugs. Backend: - shadowCallReplacementFor now matches against the configured sourceModels instead of the baked-in defaults, so custom source ids actually resolve their modelMap entry (previously a custom id fell through and was never intercepted). - PUT /api/shadow-call-settings accepts sourceModels (array of non-empty strings) alongside modelMap, persisting custom source registration. GUI: - The five built-in source rows are fixed; the shared fallback row is removed. A new custom-mapping row (text input for the source id + replacement select + Add) appends entries rendered with a delete button. Adding also registers the source in sourceModels; deleting removes it from both.
The per-source mapping UI was hard to read: the header row listed every source model in a warning badge followed by one dropdown, which read as "all models map to this target", and the per-source rows dimmed their labels at 0.6 opacity so the source-to-replacement association was not clear. Restructure the section: - header row keeps only the title, tooltip, and enable switch - the shared fallback dropdown moves to its own row explicitly labeled "Fallback for unlisted source models" (new models.shadowCallFallback i18n key, all locales) - each per-source row renders as a clear "<source> ->" label at full weight (models-shadow-source-name class) next to its replacement select Also drops the now-unused shadowSourceModelBadge import.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Document all five default shadow-call source models.
The runtime tests and PR objective define five defaults: gpt-5.6-luna, gpt-5.6-sol, gpt-5.6-terra, gpt-5.5, and gpt-5.4-mini. The English page lists two, while the translated pages list one. Users can therefore configure a replacement expecting native routing for the omitted models, but those models are intercepted by default.

📐 Maintainability & Code Quality | 🔵 Trivial
Root cause: the ShadowCallData interface (enabled, model, modelMap, sourceModels) is defined independently, with an identical shape, in two files. This PR added modelMap to both in lockstep, but nothing enforces that in the future — a later field addition to one and not the other will not necessarily surface as a compile error, since the two types are never directly compared, only used within their own file.
gui/src/pages/models-shared.ts#L70-L74: keep this as the canonical, exportedShadowCallDatadefinition (it is the oneModels.tsxalready imports).gui/src/pages/dashboard-shared.ts#L122-L122: remove this duplicate interface andimport type { ShadowCallData } from "./models-shared"instead.

Normalize modelMap keys before validation and persistence. /api/shadow-call-settings accepts padded keys, stores them unchanged, and trims sourceModels. Runtime lookup uses the trimmed source prefix as an exact object key, so the padded key cannot select its per-source replacement. Normalize keys before shadowCallModelMapErrors and persistence, reject empty results, and validate the normalized map. The custom-source GUI input already trims its value, but direct PUT requests can create this state.
