Consolidates seven beta-validated plans into the public release. Validated on nine+ topics across GENERAL, COMPARISON, RECOMMENDATIONS, and demographic-shopping classes before ship. Plans bundled in this release: - 003 Engine-emitted Pre-Research Status warning + Polymarket summarization + VOICE CONTRACT LAW 1-5 + Step 0.55 MANDATORY - 004 WebSearch deferred-tool loading (ToolSearch STEP 0) + LAW 5 universal + top-of-file imperative - 005 Supplement floor (2-3 minimum) separate from Step 0.55 pre-research - 006 Step 2.5 MANDATORY raw-file append with canonical format example + count-equality self-check - 007 Restored April 9 canonical comparison template with Quick Verdict, per-entity Strengths/Weaknesses, 9-axis Head-to-Head, Bottom Line, emerging stack + LAW 2/4 COMPARISON exceptions - 008 Person-topic GitHub handle resolution MANDATORY + LAW 1 reinforcement at Step 2 tail and Step 2.5 entry + RECOMMENDATIONS signal-weighted ranking rewrite + Polymarket post-merge topic filter (engine change, filter_items_against_topic helper + vs/versus in _NOISE_WORDS) - 009 Unified pre-flight CHECKLIST + VOICE CONTRACT formatting-authority preface + Step 0.45 Query Quality Pre-Flight (4 keyword-trap classes) + post-synthesis Sources-block self-check Beta validation topics (2026-04-18): Kanye West, Matt Van Horn, CLI vs MCP, OpenClaw vs Paperclip vs Hermes, Paperclip vs Hermes vs Open Claw, Garry Tan, Israel vs Lebanon, Best programming language for AI agents, Peter Steinberger post plan 009, Birthday gift for 42 year old man (Class 1 pre-flight fired correctly), Vincent Koc (passed). No breaking changes. No new CLI flags. No new public API. Plugin name (last30days) and marketplace name (last30days-skill) unchanged.
