# Cargo 1.75 lacks the MSRV-aware resolver (stabilized in 1.84),
# so newly published versions can break the regenerated lockfile.
# `async-lock 3.4.x` raised its MSRV to 1.85 in early 2026; it
# only appears when the `async-std` feature is enabled, which is
# excluded from MSRV coverage below, but we pin defensively in
# case the resolver pulls it in via another optional path.
# Drop these pins when MSRV is raised.

cargo update -p async-lock@3.4.2 --precise 3.3.0 || true
# MSRV is validated against the minimum realistic feature set
# (the `tokio` default plus `ctrlc-fallback`). The `async-std`
# feature pulls in `async-lock`, `polling`, and `rustix` versions
# that have raised their MSRV beyond 1.75 and is excluded from
# MSRV coverage; consumers who need `async-std` should pin their
# own toolchain to a newer minor.
