fix(config): validate codexToolMode; test(types): pin barrel re-export identity - #2119
Conversation
The field landed with #2112 in the TypeScript interfaces only. providerConfigSchema never declared it and ends in .passthrough(), so an undeclared key survived verbatim: codexToolMode: "shel" was accepted, persisted, and then silently resolved to the code_mode_only default. The operator asked for shell mode, got code mode, and was told nothing. Every neighbouring enum in that schema is validated -- apiKeyTransport, upstreamHttpVersion, codexAccountMode. This one had opted out, and passthrough made that invisible. The regression drives red: deleting the enum line fails the new test and nothing else.
The hygiene exception for the types split argued that a pure move's oracle is tsc plus the ~400 files importing through the barrel. That holds for the types, which are erased -- a wrong one fails compilation. It does not hold for the runtime values. No test imported src/types/tools.ts or src/types/wire.ts directly, so barrel and leaf were never compared to each other. A barrel that re-declared a value instead of re-exporting it would pass every existing suite. Demonstrated: forking MODEL_ADAPTER_OVERRIDE_ALLOWED into a second Set in the barrel leaves tsc --noEmit at exit 0. Two Set instances where the code assumes one is the singleton-forking hazard the split risk assessment listed as a MEDIUM program risk and left to review greps. Reference identity is the right assertion: an ESM re-export binds the same object, so toBe passes for a real re-export and fails for a copy or a wrapper. Driven red -- the forked Set fails exactly two assertions and nothing else.

Reject invalid tool modes at provider write boundaries
When a provider is created through POST /api/providers (including the dashboard's JSON editor), providerManagementConfigError does not validate codexToolMode, so a value such as "shel" is accepted, activated as code mode, and persisted successfully; only the next config reload encounters this new schema check and rejects the stored provider. Add the same enum validation to the management write boundary, preferably through a shared validator, and cover the POST path with a regression test.
Useful? React with 👍 / 👎.

Validate the custom-model tool-mode override too
When an operator sets customModels[].codexToolMode, this enum does not apply because customModels remains an undeclared top-level passthrough field. src/codex/catalog/provider-fetch.ts forwards that value, and applyRoutedCodexToolMode treats every value other than "shell" as code_mode_only, so a custom-model typo still produces the exact silent mode change this commit is intended to prevent. Validate custom-model entries as well and add a misspelled custom-model case to the regression coverage.

Check every runtime export.
Line 62 skips primitive runtime exports. Object.entries(leaf) already excludes TypeScript-only exports. A new string, boolean, bigint, or undefined export can be missing from src/types.ts without failing this test.
Remove the type filter. Assert both barrel presence and identity for every entry.
