Second Opinion v0.3.1

What's new in v0.3.1

• Diff / trend mode (-Baseline) — compare a run against a saved redacted-evidence.json from a prior run. It emits a "what changed since the baseline" section as notes only: new/resolved crashes, WHEA, TDR, and restart volume; OS-build, dump-policy, and free-space changes; readability transitions; and whether the top hypothesis changed. It never moves a tier or confidence, and it stays honest — a missing, unreadable, or wrong-schema baseline reads "no usable baseline (not a clean comparison)", never "no change", and a no-delta diff says so explicitly. With -HelperPacket it also writes a redacted baseline-diff.md.

This completes the v0.3.x feature set: the honest-evidence layer, the correctness pass, the deep-dump bridge, the Helper Packet, and now run-to-run diff.

Trust is unchanged: a deterministic scorer (the AI never ranks), read-only by design, and guarded by 33 snapshot fixtures + 131 guardrail assertions on Windows PowerShell 5.1 and PowerShell 7.

MIT licensed. See the v0.3.0 notes for the full feature list. report.html is local and unredacted; ai-prompt.txt and the Helper Packet are the share-safe artifacts (best-effort redaction).
