+- ⚠ **Card audio has failed every time:** 12 of 12 `synthesis_failed` since 10-10, each at **exactly 15.0 s**. That is the kernel's
+  `[notifications.matrix] request_timeout_seconds` (default 15) running out while synthesis is still going. The kernel speaks the Matrix
+  summons text, which includes three card ids spelled aloud, so it runs far past what 15 s covers (miranda-is ≈ 28 chars of text per
+  second; 167 chars took 5.85 s median, n=3). **Stopgap 2026-10-17 0917 (svos-dev's word): `request_timeout_seconds = 60`** (range
+  15..60; config gen `d69e7ae87d14ed45`; revert = `instance.toml.pre-matrix-timeout`). Long cards still fail at the voice app's 30 s
+  audio cap (`utterance_seconds`, max 30, about 480 chars). The real fix is a shorter spoken summons, a kernel patch whose
+  wording is Prime's call. Restore the 15 s default once it ships.
