v0.1.0-alpha.7.4

Collie alpha — automated CI build

This release was produced end-to-end by the tag-triggered
pipeline in .github/workflows/release.yml on GitHub-hosted
runners — no human build machine.

Artifacts

• Windows x64: Collie-Setup-<version>.exe (NSIS, assisted setup wizard)
  • .blockmap + alpha.yml
• macOS (arm64): .dmg + .zip (electron-updater). x64/Intel
  builds are a follow-up — they need a per-arch staged Python
  runtime, not yet implemented.
• Linux x64: .AppImage

SHA256SUMS.txt covers every attached artifact. The Windows
build additionally carries collie-build-provenance.json
(clean-tree git SHA + build time) and
collie-artifact-provenance.json (per-artifact hashes), written
by the repo's own release tooling.

Alpha caveats

• macOS is unsigned (no Apple Developer certificate yet).
  Gatekeeper will report "Apple cannot check it for malicious
  software" — open via right-click → Open, or System Settings →
  Privacy & Security. Notarization needs a $99/yr Apple Developer
  account (APPLE_ID / APPLE_APP_SPECIFIC_PASSWORD /
  APPLE_TEAM_ID secrets) — a follow-up.
• Windows Authenticode signing is wired but only activates
  when the WIN_CSC_LINK / WIN_CSC_KEY_PASSWORD code-signing
  certificate secret is provisioned for the repo. Until then the
  installer is unsigned and SmartScreen may warn.
• Asset provenance is recorded: branded art is
  owner-created for Collie (excluded from MIT reuse) and
  third-party marks are nominative-use only, per
  docs/operations/release/asset-provenance.md (SHA-256
  manifest in asset-provenance.sha256).
• This is a draft release: a maintainer reviews the checksums
  and publishes it deliberately.
