…olects Most of this skill tells the editor what to remove. This adds the inverse — what to leave alone, and how to decide. Sourced from Wikipedia: Signs of AI writing (revision fetched 2026-05-01), specifically the "Ineffective indicators", "Signs of human writing", and "Differences between LLMs" sections. Three subsections, no new patterns: - "What NOT to flag (false positives)" — the indicators that look AI-coded but are actually neutral (perfect grammar, em dashes alone, curly quotes alone, formal vocabulary, common transition words). The over-editing risk is real: if the skill is applied too aggressively, it strips legitimate prose. Closes with the "clusters matter, isolated signs don't" rule. - "Signs of human writing (preserve these)" — positive markers that should be left untouched: specific detail, mixed feelings, era-bound references, sentence-length variation, parenthetical self-corrections, and the November 30, 2022 cutoff for ruling out AI involvement entirely. - "LLM Idiolects" — quick triage notes per model family (ChatGPT/Grok verbose with artifacts; Gemini/Claude concise, no curly quotes by default). Tendencies, not rules. No pattern-count change. No README changes (the README's pattern table is unaffected since this section is meta-guidance, not new patterns). No version bump.

Brings the fork's main branch in line with the maintained local v2.6.0, consolidating the changes that are also opened as focused PRs against blader/humanizer (blader#111, blader#112, blader#113): - §7 expanded with era-specific AI vocabulary clusters (GPT-4 / GPT-4o / GPT-5 eras), plus 'bolstered' and 'meticulous' added to the master list and a literal-vs-figurative caveat. - §21 renamed to "Knowledge-Cutoff Disclaimers and Speculative Gap-Filling"; covers the retrieval-augmented "maintains a low profile" / "keeps personal details private" speculation pattern. - New patterns §30-34: reference-markup artifacts (turn0search0, oaicite, utm_source=chatgpt.com, etc.), placeholder leftovers, Markdown/wikitext contamination, formal "Conclusion" closers, didactic disclaimers. - New Detection Guidance group: what NOT to flag (false positives), signs of human writing to preserve, and per-model LLM idiolects. Frontmatter version bumped to 2.6.0. README pattern table updated (29 → 34 patterns) with a new Artifacts and Contamination section and a pointer to Detection Guidance. WARP.md count corrected from the stale "25 patterns" to 34. Sourced from Wikipedia: Signs of AI writing (revision fetched 2026-05-01).

Summary
Most of this skill tells the editor what to remove. This adds the inverse — what to leave alone, and how to decide.
Sourced from Wikipedia: Signs of AI writing (revision fetched 2026-05-01), specifically the "Ineffective indicators", "Signs of human writing", and "Differences between LLMs" sections.
Three subsections, no new patterns and no version bump:
The new section sits between §29 (Fragmented Headers) and the Process section. README and WARP.md are unchanged — the README pattern table is unaffected since this is meta-guidance, not new patterns.
Why this matters
The current skill is a strong "what to fix" guide but doesn't push back against over-editing. In practice, applying any pattern-based rewriter too aggressively is the failure mode — humans get their voice flattened. A short "what NOT to flag" sidebar plus a positive-signals list keeps the editor honest.
This PR is independent of #111 (era vocab + gap-filling) and #112 (patterns 30–34), and can land on its own without rebasing.
