- `slop4` (`slop4.h`) per-position stateful shaper (`12 b/pos` in `window.cpp` + gpu `mtp_slop_pen` in `mtp_chain.metal` with `STRATA_METAL_MTP_SLOP=1`), gated strictly on `PROSE && !TOOL && !FENCE`, with clause-entry branch-point penalties, `slop4::hold()` `<|im_end|>` mass preservation, `</think>\n\n` `step0` empty-turn guard, `slop_scan`, and `scr_relocate` support
- monroe prior log-odds llm-ism miner (`mine_llm_isms_from_transcripts.py`, pure per-order unigram+uniform prior with zero self-pooled weight) partitioning structural speech acts (`phase3_sentence_surgery` in `prepare_phase3_sft_data.py`, in-place span deletion preserving markdown/fences/kaomoji + r-tuning word-boundary abstention) vs surface lexical cliches (`phase4_lexical_ftpo`)
- strata `v0.1.45` `serve/` & `tools/strata_tokenizer.py` ports + local hardening: incremental `PromptEncoder` prefix/plain-span reuse capped at `PROMPT_ENCODER_KEEP_MAX = 16` with rejected-prompt forgetting, bounded tool-call parser scan cursor, content-keyed json lru logit-bias cache (stale `_last` identity shortcut removed), macos iokit/metal telemetry (`MTLCreateSystemDefaultDevice` cached once and `objc_release`d), `STRATA_OMIT_IMAGES_WHEN_NO_VISION=1` text-only image omission, and anthropic hard thinking budgets + `answer_room` answer reservation
