0.3.45

[FoxsterDev]

Current Git UPM install URL:

https://github.com/FoxsterDev/xuunity-mcp.git?path=/packages/com.xuunity.light-mcp#v0.3.45

Changed

• Released v0.3.45 package metadata, server metadata, package manifests, and Git UPM examples.
• Made setup fail closed on stale canonical Git UPM pins, helper versions,
  helper integrity manifests, and client launcher flavor mismatches. Setup plans
  now upgrade older pins after approval, refuse automatic downgrades or custom
  source rewrites, and reject apply when the reviewed manifest changed.
• Reworked the public one-prompt install contract around the canonical
  v0.3.45 source and tagged README. Existing helpers are verified before use,
  native Windows Codex blocks migrate from bash/run.sh to
  cmd.exe/the refresh .cmd without replacing unrelated config, and client
  restart plus live-tool proof is required before tests.

Fixed

• Prevented stale/reused bridge PIDs from being trusted as Unity process
  identity. Automatic recovery no longer treats editor-open permission as
  force-termination permission, revalidates exact project ownership before an
  explicitly authorized termination, and Windows taskkill no longer uses
  the descendant-tree /T flag.
• Added a safety-epoch, hash-verified helper install manifest and published the
  legacy server.py version marker last, so interrupted or mixed-version
  helper rollouts are refreshed instead of executed.

Validation

• Host Python unittest suite passed: 452 tests with 13 expected skips.
• Public site Playwright checks passed: 39/39, including the 320 px viewport
  and clipboard safety-contract assertion.
• Release metadata consistency, documentation freshness, and public-release
  safety checks passed for 0.3.45.

Added

• Added unity_sdk_generated_diff_guard and sdk-generated-diff-guard, a
  compact, host-side SDK rollout proof for Git-tracked generated files. It
  compares each requested path to a named Git baseline and fails closed when a
  required marker is absent, a tracked generated file disappears, an expected
  previous native version remains, or an unallowlisted generated-file change is
  present. The guard writes a JSON proof
  under the project's ignored MCP evidence directory by default.
