+## 77. What's New shared with Play rejected on the App Store (2.3.10)
+- **Symptom:** a Mac App Store version was rejected under Guideline 2.3.10 (Accurate Metadata): its What's New came
+  from release notes shared with Google Play and had "Google Play Games" and "Android" lines. storebound wrote it
+  without a word (the old check was a warning in the editor only).
+- **Cause:** one notes source for both stores, no per-store split, and no write that refused other platforms. Google
+  Play's Metadata policy is the mirror case (iOS, iPhone, App Store, Game Center, TestFlight in Play text).
+- **Do:** tag store-specific lines `[play]` / `[apple]` in shared notes (whats-new skill); `storebound check` must
+  show no `other platform` line. A functional mention (a "Continue with Google" / "Sign in with Apple" button) is the
+  owner's call: `listing.allowPlatformMentions: [{ store, text, reason }]`. Never add an entry yourself.
+- **Guard:** `cli/lib/cross-store.ts` (term lists, per locale / field / line, the allowlist, `notesForStore`).
+  Refused before anything is sent, dry runs included: `apple listing`, `play listing`, `play release` /
+  `play upload` (release notes), `listing set`, `whats-new check` / `apply`, the desktop editor and `storebound edit`
+  (`appleLocaleIssues` / `playLangIssues` errors). `check` / `validate` blockers (`other-platforms`), `scan` rules

+## 78. `storebound api ... --yes` piped or redirected became a silent dry run
+- **Symptom:** `storebound api apple <write> --yes | tail` (or `> out.json`) printed a dry run and exited 0; the
+  owner thought it was sent. Happened twice.
+- **Cause:** writes need an interactive terminal; without one the gate fell back to a dry run.
+- **Do:** run writes without a pipe or redirect in a terminal, or use the dedicated storebound command.
+- **Guard:** `decide` in `cli/api/gate.ts` refuses (`NOT_A_TTY`): exit 1, the message on stderr, nothing sent, the
+  dedicated command named. Without `--yes` a write is still a plain dry run. `tests/api.test.ts`.
