fix(deps): bump anyhow → 1.0.103 (RUSTSEC-2026-0190) - #54
Merged
Conversation
RUSTSEC-2026-0190 (unsound): `Error::downcast_mut()` on an error that had context added via `Error::context()` violates borrow rules → UB. Newly published advisory; cargo-deny's advisory DB updated and now fails the engine CI on every open PR (unrelated to those PRs' changes). Fixed the RustSec-recommended way — patch bump to the first non-affected release (>=1.0.103). Engine workspace only (the CI-gated lockfile); semver-compatible, no API changes. `cargo deny check advisories` → ok. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Why
cargo-deny started failing the engine CI on every open PR (#52, #53, …) after RustSec published RUSTSEC-2026-0190 — an
unsoundadvisory againstanyhow:Error::downcast_mut()on an error carryingError::context()violates borrow rules → undefined behavior (dtolnay/anyhow#451). This is environmental (advisory DB updated), not caused by any PR's diff.Fix
Patch bump to the first non-affected release, as RustSec recommends (
>=1.0.103). Engine workspaceCargo.lockonly — that's the lockfile thecargo-denyjob gates. Semver-compatible, no API changes;cargo deny check advisories→ ok locally.Merge order
Merge this first, then rebase/update #52 and #53 so their CI goes green.
