-# Model pinning rationale:

+# claude-sdk and codex reject "mock-model" as an unknown model (they validate

+# Create a GitHub Release entry (the `…/releases` page) when a version tag is
+# pushed. This is METADATA ONLY — it does NOT build or publish any installable
+# artifact. PyPI publishing lives in the central secure-release repo
+# (databricks/secure-public-registry-releases-eng → `omnigent` workflow), on
+# hardened runners with OIDC Trusted Publishing and a mandatory dependency
+# scan. Keeping those concerns separate is deliberate (see RELEASING.md):
+#
+#   * This job runs NO project or third-party code — no build, no `pip
+#     install`/`npm ci`, no tests. Its only action is SHA-pinned
+#     `actions/checkout` plus `gh release create`. A malicious tagged commit
+#     therefore cannot execute anything here.
+#   * It uses the ephemeral `GITHUB_TOKEN` (no stored secret / PAT). The single
+#     elevated scope, `contents: write`, is the minimum GitHub requires to
+#     create a release and nothing else in the job uses it.
+#   * It attaches NO wheels. The release carries only generated notes and the
+#     source tarball GitHub auto-attaches, so PyPI (the scanned, securely
+#     published channel) stays the single source of installable artifacts.
+#   * The release is created as a DRAFT: a human verifies/edits the generated
+#     notes and publishes it (ideally after the prod PyPI publish lands), so a
+#     bot never makes a public release on its own.

+ * - `allow-popups` + `allow-popups-to-escape-sandbox` — let links/`window.open`

+ *
+ * NOTE: we deliberately omit `allow-same-origin`. The iframe is fed via
+ * `srcDoc`, which would otherwise inherit the embedder's origin — combining
+ * that with `allow-scripts` would let untrusted artifact code reach into the
+ * parent app (cookies, storage, DOM). Withholding it gives the document an
+ * opaque origin, so scripts run fully sandboxed away from the host page.
+ *
+ * Accepted trade-offs from these flags: `allow-popups-to-escape-sandbox` lets
+ * artifact JS spawn fully-capable new windows (phishing / window-spam surface),
+ * and `allow-modals` lets it raise blocking `alert`/`confirm`/`prompt` dialogs.
