Fix prediction workflow and add X source evidence

[kriptoburak]

Summary

• add the current TweetClaw install, API key, and OpenClaw allowlist setup
• map public X results into the existing candidate and benchmark schemas
• keep post text untrusted and exclude credentials, private data, and drafts
• preserve Cheat on Content as the scoring and blind-prediction authority

Independent Repository Repairs

Allow valid retrospective edits

The immutability hook previously searched a multiline old_string with grep -F. grep treated every line as a separate pattern. Empty lines matched the protected section, so valid multiline ## 复盘 edits were blocked.

The hook now reconstructs the proposed file and compares protected prediction sections exactly. It:

• allows metadata and multiline retrospective edits
• allows a new append-only versioned prediction
• blocks direct, broad, and replace-all prediction changes
• fails closed when it cannot verify the edit

A 7-case shell regression suite covers those boundaries.

Finish strict Skill frontmatter compatibility

The recent strict-loader repair missed 4 argument-hint values containing colons. This commit quotes the remaining values in:

• cheat-learn-from
• cheat-predict
• cheat-publish
• cheat-retro

All root and sub-Skill frontmatter now parses with strict YAML.

Validation

• bash hooks/prediction-immutability_test.sh (7 passed)
• LinkedIn extraction checks (7 passed)
• WeChat adapter tests (3 passed)
• WeChat runner failure-contract test
• bash tools/diff_pct_test.sh (3 passed)
• Bash syntax for every shell script
• Python compilation for adapters and tools
• JSON parsing for every tracked JSON file
• strict YAML parsing for every root and sub-Skill frontmatter block
• ShellCheck for the changed hook and regression suite
• GitHub Markdown rendering for every touched document
• touched-document local-link validation
• current TweetClaw commands verified against its canonical README
• git diff --check

The branch is rebuilt as one verified signed commit on current upstream main.

Rebuilt this PR on current main. Beyond the X source workflow, it now fixes 2 confirmed repository problems: multiline retrospective edits no longer trip the prediction guard, and all 4 remaining colon-bearing argument-hint values load under strict YAML. The new hook suite covers 7 allow/block boundaries, every available repository test passes, and the single commit is verified. Ready for review.
