Snapshot of every non-log artifact under audit-runs/ from audits 003 through 058: findings.md per audit, comparison CSVs, probe diffs, schema docs, register-dump txts, lr-trace JSONL streams, the saved canary patch diffs, etc. ~284 files / ~52 MB total. Excluded (per .gitignore): probe stdout/stderr/log streams (the raw firehose), guest-memory dumps under audit-026/027/029 (4.5 GB of .bin files; *.bin pattern added to .gitignore this commit). Also adds the orphan audit-058-sub825070F0-activation directory that a subagent accidentally created at project-root instead of under xenia-rs/audit-runs/; relocated to its proper home. Purpose: cross-machine continuity. With these summaries committed, a fresh clone gives the next session the full per-audit context (findings + tables + cascade predictions) without dependence on local-only working tree.
