v3.15.0

Added

• Wall-of-text replies — reply-length text (roughly under 150 words, four or more sentences) delivered as one unbroken paragraph with no line breaks anywhere, the shape LLMs default to in conversational registers (issue/PR comments, chat, DMs, casual email) where humans instead break at thought boundaries. Catalog goes from 51 to 52 detection categories. LLM-judgment rule, not a detector type: a first pass implemented it as a structural gate (reply-length + sentence floor + zero newlines) and it broke the "repeated Tier 1 phrase does not inflate score linearly" fixture on review — turned out "one paragraph, no internal line break" is just what an ordinary short paragraph looks like, not an AI-specific shape, so an unconditional detector would fire on routine human prose. Reverted per the precision-over-recall principle in CONTRIBUTING.md; documented in detector/CATEGORIES.md §C with the reasoning.
• Recap-flattery opener — replying to a person by summarizing their own work back at them with praise before getting to the point ("Thanks for all the legwork here — the X and Y you worked through are what made Z possible"). The reader already knows what they did; the recap performs appreciation instead of conveying information. Catalog goes from 52 to 53 detection categories. LLM-judgment rule (no detector type — the tell is redundancy with information the reader already holds, which requires reading both sides of an exchange, not a fixed phrase).

Changed

• Formatting — extended the curly-quotes weak-signal tier with immaculate typography in casual registers: perfect spacing, punctuation, and capitalization in a context humans type fast (comments, chat) is corroborating evidence, never conclusive alone. Also flags the inverse: when editing a human's casual text, preserve their typos — smoothing them away erases the fingerprint that marks the text as theirs. LLM-judgment rule; folded into the existing Formatting section (same tier as curly quotes), no new category.
• Cursor port (cursor-rules/avoid-ai-writing.mdc) caught up from v3.12.0 to v3.15.0: ported the 3.13.0 (speculative scenario openers, "deeply" conditional Tier 2, multi-negation countdown, invented concept labels, historical analogy stacking) and 3.14.0 (vague third-party validation) rule changes it had missed, plus this release's three additions.

Source

• Observed in the wild: a maintainer on a GitHub issue flagged an assisted-sounding reply with "I prefer to talk human to human." The block-paragraph shape and the recap of the maintainer's own prior work were the tells, not any single word. Name and repo withheld.
