`wallet_core::session::Session` is the only place decrypted key material lives between commands: one wallet open at a time, its signers and, when the file carried a phrase, its seed. Every signature goes through `Session::sign`, which applies the idle rule before it looks at the key, so a stale session refuses rather than signing one last time. Time is passed in, so the rule is tested at 59, 118 and 119 seconds without waiting. The seed is now a heap allocation behind a wiping box. Moving an inline 64-byte array through `Some(...)` and a function argument can leave copies in dead stack frames that no destructor visits; moving a box moves a pointer. A Linux test unlocks with a runtime-built seed and a signer whose secret is a second runtime-built pattern, locks, then reads every writable anonymous mapping in /proc/self/mem and asserts neither pattern is anywhere in the process. It passes in debug and release. The comparison copies are XOR-masked so the test cannot find itself. In the app: `unlock` opens a file, turns its phrase into a seed and drops the phrase; `lock` and `session_status` do what they say; a ticker thread applies the idle rule every five seconds and emits `session:locked` so the lock screen appears without a click. Ten minutes until settings exist. Closes #17 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014ftBXYuba8ARhQeF74oUgW
