docs(rectification): BUG-1047 records, progress, device checklist, ledger ERR-110/111
- BUG_HISTORY BUG-1047 (investigating), PROGRESS with timing estimates, A/B
evidence, diagnostics guide, test diffs and env gaps.
- CHANGELOG (Skill version not bumped), docs/testing checklist + headless
screenshots, tasks README row -> 待验收, BLOCKED entry.
- pre-work ledger: ERR-110 (byte-identical engine perf changes still trip the
frozen-scoring integrity gate), ERR-111 (Shadbala fingerprint depends on
PYTHONHASHSEED).
