From 20dc69186dcee3a3a8ceec672c01f2bf7eddd8f1 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 9 Nov 2026 12:54:18 +0000 Subject: [PATCH 1/3] fix(deps): move rmcp to 3.9.0 off three RustSec advisories cargo audit fails on rmcp 3.5.0 (crates/echidna-mcp) with RUSTSEC-2026-0457 (fixed >=3.7.0), RUSTSEC-2026-0461 (>=3.6.0) and RUSTSEC-2026-0462 (>=3.9.0), published after main last passed the Dependency audit check. `cargo update -p rmcp` moves rmcp and rmcp-macros to 3.9.0, inside the existing "3" requirement; no other entry changes.

Each of those lines recovers a callback's own `*@This()` from the type-erased `*anyopaque` it was registered with (runtime_owner.Work .context, or a std.mem.Allocator vtable's ptr), so the cast restores the original type and alignment. Fixed at source with a reasoned inline `hypatia: allow` per rule on each line, as the scanner documents, rather than a baseline entry. No code change: comments only. Checked by simulating ScannerSuppression.inline_allowed?/4 and directive_re at hypatia 82396d81 (the CI pin): 18 unsuppressed findings on main, 0 with this change. The scanner itself could not be built here (hex.pm is unreachable).
