Waters ChurchandClaude Fable 5.1 0929af46ca SPL Meter 0.5.0: the capture tool ships prebuilt, for Apple silicon and Intel
Same move as Timers 1.7.0. The capture tool existed only where the macOS
app build had compiled it, with the module trying swiftc on the booth as a
fallback — NA has been logging "spawn spl-capture ENOENT" since its
catalog install. Under the module guide's rule it now ships built:
bin/spl-capture-macos-arm64 and bin/spl-capture-macos-x86_64, signed with
the Developer ID (hardened runtime, audio-input entitlement), from
native/spl-capture.swift via native/build.sh. captureTool() picks the
binary for this platform; where there is none — Windows, until a Windows
implementation exists — measurement reports itself off in the health line
and the device picker while the module stays mounted. The runtime build
and its "building…" state are gone, and the old top-level binary is no
longer gitignored.
