 - OpenAI model lists are filtered to models that are expected to work with the backend's Responses API implementation.
- Gemini model lists are loaded from Google's native Models API and filtered to Gemini `generateContent` model ids.
 - `hermes-agent` is included only when `HERMES_AGENT_API_KEY` is configured. Set it to Hermes `API_SERVER_KEY`, or any non-empty value if that local server does not require auth. `HERMES_AGENT_API_BASE_URL` defaults to `http://127.0.0.1:8642/v1`; set `HERMES_AGENT_MODEL` only when you need an additional fallback/override model id.
 - The backend loads provider model lists at startup and refreshes them about once every 24 hours. If a later provider refresh fails, the response keeps the last loaded model list for that provider and sets `error` to the latest failure message.

-## Release Workflow
- iOS release tags use the annotated tag namespace `release/ios/vX.Y.Z`; increment from the latest existing `release/ios/v*` tag.
- Tag message convention is `ios: X.Y.Z`, for example `git tag -a release/ios/v1.13.5 -m "ios: 1.13.5"`.
- Push the release commit and tag together with `git push origin <branch> release/ios/vX.Y.Z`.
- Fastlane derives the marketing version from the release tag and stamps `ios/Apps/Sybil/project.yml` during CI, so do not manually bump `MARKETING_VERSION` for normal tagged releases unless explicitly requested.

+# TestFlight Release CI
+
+Gitea Actions publishes iOS releases from tags that match:
+
+```sh
+release/vN.N.N
+```
+
+For example:
+
+```sh
+git tag release/v1.10.0
+git push origin release/v1.10.0
+```
+
+The release job runs on the `xcode` runner label, imports the signing p12 into
+a temporary per-user keychain, makes that keychain the user default for the
+duration of the job, installs the App Store provisioning profile in both the
+legacy MobileDevice directory and the Xcode UserData directory used by newer
+Xcode releases, builds and uploads the app with fastlane, then creates or
+updates the matching Gitea release with the generated IPA as an asset. The job
+restores the previous user default keychain and deletes the temporary signing
+keychain and installed profiles in an `always()` cleanup step.
+
+Required repository secrets:
+
+```text
+APP_STORE_CONNECT_API_KEY_ID
+APP_STORE_CONNECT_API_ISSUER_ID
+APP_STORE_CONNECT_API_KEY_CONTENT
+APPSTORE_CERTIFICATES_FILE_BASE64
+APPSTORE_CERTIFICATES_PASSWORD
+APPSTORE_PROVISIONING_PROFILE_BASE64
+```
+
+Generate or refresh the signing assets locally with:
+
+```sh
+cd ios
+fastlane ios create_ci_signing
+```
+
+The generated `build/signing/ci-secrets.env` file is ignored by Git. Copy its
+certificate and provisioning profile values into the repository secrets listed
+above. The workflow uses the `Sybil AppStore CI` provisioning profile name by
+default.
+
+Fastlane keeps two signing names separate. `SYBIL_CODE_SIGN_IDENTITY` is the
+exact certificate common name used when exporting a local p12 for secrets, while
+`SYBIL_XCODE_CODE_SIGN_IDENTITY` defaults to the certificate SHA-1 fingerprint
+that Xcode uses during archive. `SYBIL_EXPORT_SIGNING_CERTIFICATE` defaults to
+the generic `Apple Distribution` selector used in the export options.
+
+The Release signing settings are also present in `Apps/Sybil/project.yml` so
+XcodeGen emits a manually signed App Store archive configuration. CI passes the
+installed provisioning profile UUID to Fastlane as
+`SYBIL_PROVISIONING_PROFILE_UUID`; Fastlane writes that UUID into the generated
+project before archiving. CI also passes the temporary keychain path as
+`CODE_SIGN_KEYCHAIN` so Xcode searches the disposable keychain for the imported
+Distribution identity.
+
+If the Apple team has reached the Distribution certificate limit, set
+`SYBIL_SIGNING_CERTIFICATE_ID` to the portal id for a certificate whose private
+key exists in the local login keychain before running `create_ci_signing`. The
+lane will export the local identity and create the provisioning profile against
+that existing certificate instead of creating another Distribution certificate.
+
+If `create_ci_signing` fails with an expired or missing agreement error, the
+Apple Developer Program account holder must accept the current agreements in
+App Store Connect before new certificates or provisioning profiles can be
+created through the API.
+
+The workflow uses Gitea's built-in `GITEA_TOKEN` for release creation and asset
+upload, with `contents: write` permissions. In Gitea this covers release asset
+publication.
