Module build_info 

Build identity of the running binary.

Between releases every dev build reports the same crate semver, so version-keyed signals — the plan-05 “engine version changed → re-read the tool roster” hint and the plan-02 mutation-stamp / ENGINE_VERSION_SKEW comparison — could never fire in dogfood or field use. build.rs captures the git commit at build time (MEMSTEAD_BUILD_SHA, empty outside a git checkout); this module renders the full build version every version-carrying surface serves: CLI --version, both MCP flavours’ serverInfo.version, the overview’s _engine_version, and the per-mem mutation stamp.

Constants

BUILD_SHA

The short git sha of the commit this binary was built from, with a -dirty suffix when tracked files were modified at build time. Empty for builds outside a git checkout (crates.io, vendored trees) — emptiness, not absence, is the sha-less signal.

Functions

full_version

The full build version of the running binary: the bare crate semver (crate::ENGINE_VERSION) when no build sha exists, else <semver>+g<sha>[-dirty] (semver build-metadata syntax, so the value still parses as a semver::Version). Two dev builds of the same crate version compare unequal whenever their commits differ — exactly the property the skew stamp and the roster-refresh hint need.
