+Smoke mode remains the default for compatibility. Without explicit overrides it retains the original rewrite instruction, 128-token allowance, 600-second time limit, and original decoding options. The new repetition guards and document caps apply only to opt-in rewrite mode. It checks zero-strength greedy text/token equivalence, nonzero injections, normal hook restoration, restored baseline text, and disabled parameter gradients. Smoke mode intentionally does not apply document-length salvage, so these equivalence checks compare raw generations.
 
 Seven CPU policy tests and Python/shell syntax checks passed for this update. The updated CUDA path has **not yet been run on an ARC GPU**. A prior version was reported by the author to pass on `tc-dgx005` on November 12, 2026; that does not validate this revision. Emotional effectiveness, semantic fidelity, and behavior at extreme settings are not guaranteed.

 With greedy decoding, the checks require zero-strength and baseline decoded text/token counts to match, nonzero injections in the positive and negative cases, restored hook counts, restored baseline text/token counts, and disabled backbone gradients. Positive and negative outputs need not differ for these checks to pass. Settings that suppress all effective intervention are unsuitable for the nonzero-injection checks.
 
-Smoke mode deliberately omits document-length salvage so that it compares raw generations. It saves completed conditions incrementally and marks `checks_complete` only after assertions pass. It does not compare logits, full token sequences, parameter hashes, or independently measured per-step RMS bounds. Run with ordinary Python rather than assertion-disabling optimization flags.
+Smoke mode defaults to the original 128-token allowance and 600-second time threshold. Its original instruction permits changes in phrasing, imagery, and emotional expression while preserving the passage’s main subject and recognizable situation. It omits the new repetition penalty, n-gram guard, and document-length salvage so that existing commands retain their original generation configuration and compare raw generations. It saves completed conditions incrementally and marks `checks_complete` only after assertions pass. It does not compare logits, full token sequences, parameter hashes, or independently measured per-step RMS bounds. Run with ordinary Python rather than assertion-disabling optimization flags.
 
 For the November 13 revision, seven CPU policy tests passed, Python and shell syntax were checked, and CLI loading was verified. Tests cover such behavior as unchanged requested controls, paragraph allowance accounting, draft retention, sentence cleanup, and continuing after a failed chunk. They do not execute the CUDA model. The current revision has not yet been run on an ARC GPU. A successful GPU run was reported for an earlier revision on November 12; it is historical evidence, not validation of the current code.
