# AeX402 v0.13.10 > Released 2026-08-08 Housekeeping that makes [v0.13.9](/releases/v0.13.9/RELEASE_NOTES.md) stick. ## The zero stays zero 44 places where a missing field or an unexpected type from JSON was a **panic** are now errors. Finding them cost a day; keeping them gone is a grep, and a release can no longer be built if one comes back. The check allows a `.?` whose type is already proven by an enclosing switch, via an inline marker — a gate you can satisfy honestly rather than one you disable. Exactly one such case exists in the codebase and it is marked. ## The daemon survives its own corrupt state `aex402-daemon` read its state file with the same unchecked access. A truncated or hand-edited file panicked it on the first bad key, killing a long-running process and taking every healthy entry with it. Verified by actually corrupting a file rather than reading the diff: fed it a missing key, a wrong type and a non-object. It starts cleanly where it previously died on load, skipping what it cannot read. --- Install or upgrade: ```sh curl -fsSL https://aex402.com/install.sh | sh ``` Downloads and checksums for all six platforms are at . The manifest is signed with an offline key and the installer refuses anything it cannot verify.
