Replace superseded preliminary-round deliverables with the finals repository identity, provenance boundary, Apache-2.0 and CC BY-SA 4.0 licenses, third-party notices, and a truthful AI-use summary.

The public preliminary history is preserved. This commit establishes the finals rewrite baseline at its actual submission time and does not backdate or rewrite earlier public objects.

AI-Use: OpenCode/DeepSeek V4 Pro and Codex/GPT-5.6 usage boundaries are documented; no model output is treated as experimental evidence.

Human-Review: 范洪旭 reviewed the release scope, attribution, privacy boundary, and final submission responsibility.
