v0.1.0-preview.4 FINAL CANDIDATE (merged main) — 非正式 preview.4，仅供最终字节验收

NOT the formal v0.1.0-preview.4 release

This is the merged-main final candidate for byte-level acceptance by the original external test machine. The formal v0.1.0-preview.4 tag is created ONLY after this candidate passes the full lifecycle regression externally.

• git_commit: 5bb2635624585318aa005a0fc1d8c2b302c8a183 (merged main)
• lineage: PR #209 merge dac9fca (RC.5 fix branch 23 commits) → release-prep 1d6f7f5 → truth-boundary header fix 5bb2635
• images: 9/9 identity-identical to RC.5 (recomputed from shipped tar, not assumed)
• gate: 2471 passed / 0 failed / 20 skipped (re-run live at merged main)

Dev-machine verification (this round)

Check → Install → Doctor OK(ok) → Status absent → Start (healthy, page/api 200, 405/404/403) → Stop → re-Start → Cleanup #1 (install manifest removed (was present and consumed by cleanup --apply)) → Cleanup #2 (no install manifest found from the start) → zero residue.

Truth boundaries (frozen, unchanged)
