From c035749dbbe2d10ddfb8a84bc116ce11b88832f3 Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Wed, 26 Aug 2026 23:26:52 +0000 Subject: [PATCH 01/12] Record Cycle 8 mix publishability gates and fail-close product promotion. Five gates after the merged mix freeze: reproducibility and visibility pass; Latin-1/literal-search, Mn/default-ignorable sanitizers, and single-detector confirmation fail. Mix stays out of the public CLI. Do not retag v0.3.0.

software and evidence gates.

From 0d58e3c37efb0875bcf3929ff07ba084a6c64726 Mon Sep 17 00:00:00 2001

Subject: [PATCH 03/12] Record independent DeepMind 30-key mix 0/192 and
 DistilGPT2 n=16.

Cross-detector PASSes on Hugging Face nine-key GPT-2 Weighted Mean plus
Google synthid-text 30-key GPT-2. DistilGPT2 n=16 is HYPOTHESIS
second-model transfer, not confirmation-scale. Sanitizer still FAILs:
width-0 assigned insertions are Mn, Me, or Cf, and all 13 enclosing
marks change Chromium pre pixels. Mix stays out of the public CLI.

+Status: `HYPOTHESIS`. n=16. Not mix-freeze confirmation. Not confirmation-scale. Not product authorization.

+Seed `1090000` was reserved in `global-seed-ledger-v1` before generation. The corpus is DistilGPT2 continuations from `synthid_text.SynthIDGPT2LMHeadModel` with DeepMind `DEFAULT_WATERMARKING_CONFIG` (30 keys). Detection used official `synthid_text.logits_processing.SynthIDLogitsProcessor` weighted mean at frozen threshold `0.5570987654320988`.

+# Cycle 8 mix DeepMind 30-key transfer (seed 920000)
+
+Status: `HYPOTHESIS`. Not confirmation. Not a second model. Not product authorization.
+
+Reserved Cycle 8 secondary exploratory seed `920000` (`invisible carrier development`) generated watermarked and unwatermarked 64-token continuations with `synthid_text.SynthIDGPT2LMHeadModel` on `openai-community/gpt2` using DeepMind `DEFAULT_WATERMARKING_CONFIG` (30 keys). Detection used official `synthid_text.logits_processing.SynthIDLogitsProcessor.compute_g_values` with weighted mean at the frozen Cycle 6 threshold `0.5570987654320988`.
+
+This is an independent **configuration and implementation**: Google `synthid-text` mixin generation and official logits processor, 30 keys, sampling table 65536. It is not Hugging Face `SynthIDTextWatermarkingConfig` and not the Cycle 6 nine-key adapter. It is still GPT-2, so `second_model` is false.
+
+Frozen mix apply `u034f-ufe00-letter-alt-v1` was scored on these fresh texts. Residual mix text is not stored in the scorecard; source texts are in `samples.json` so mix hashes can be replayed.
+
+## Result

+| Identity WM | **16/16** |
+| Mix WM | **0/16** |
+| Identity UW | **0/16** |

+
+Mix WM max score `0.5063963600986625`. Visible projection passed on every row.
+
+Do not treat this n=16 look as mix-freeze confirmation. Do not generate `950000`. Do not retune mix sites.

Subject: [PATCH 04/12] Keep Unicode feasibility scans portable across Python
 versions.

Frozen H9 and closed-set hashes stay the CPython 3.12 snapshot. Live
scans on 3.11 and 3.13 still must find no stronger Priority-Zero
mechanism. Mix stays out of the public CLI.

Subject: [PATCH 05/12] Record H12 control-mix sanitizer research without
 product authorization.

DEL and C1 except NEXT LINE survive the required sanitizers and keep
Chromium pre/textarea/contenteditable pixels. Independent seed 1100000
n=16 is control-mix 0/16 WM with identity 15/16. Mix sanitizer stays
FAIL. The public CLI stays empty.

+# Cycle 8 control-mix diagnostic (seen seed 920000)
+
+Status: `HYPOTHESIS`. Seen corpus. Not independent generation. Not confirmation. Not mix-freeze confirmation. Not product authorization.
+
+This rescores the already generated DeepMind 30-key GPT-2 n=16 texts from seed `920000` after applying `cc-del-c1-letter-alt-v1` (H12). Residual control-mix text is not stored. Source texts remain in `evidence/cycle8-mix-deepmind-30key-920000-n16-2026-08-27/samples.json`.
+
+Detection used official `synthid_text.logits_processing.SynthIDLogitsProcessor.compute_g_values` with weighted mean at the frozen Cycle 6 threshold `0.5570987654320988`. Identity and frozen mix were rescored on the same rows as a scorer check.
+
+Required sanitizers (Mn-strip, default-ignorable-strip, Cf-strip, NFC, NFKC, NFKD, frozen Cycle 6/7 variants, and the combination) kept every control-mix string. Visible projection passed on every row. Mix publishability sanitizer stays FAIL because mix still uses U+034F / U+FE00.
+

+| Mix UW | **0/16** |
+
+Control-mix WM max score `0.505336937084192`. Do not treat this seen n=16 look as confirmation. Do not generate `950000`. Do not retune mix sites. Public CLI stays empty.

Subject: [PATCH 06/12] Record H12 Chromium pixels as host-dependent.

GitHub Actions Chromium rejected the full control-mix apply while one
research host matched. Do not treat that as a product visibility PASS.
Mix sanitizer stays FAIL. The public CLI stays empty.

Subject: [PATCH 07/12] Record H13 post-sanitizer mechanism class without
 product authorization.

No measured Unicode-string family is simultaneously sanitizer-surviving,
Chromium-portable, ordinary plain text, and Priority-Zero safe. This is
a classification, not a Unicode re-scan. Mix sanitizer stays FAIL. The
public CLI stays empty.

 - Cycle 8 mix freeze one-shot confirmation on preregistered seeds `830000` / `840000` / `850000`: mix **0/192** raw transformed WM, mix UW **0/192**, visible **192/192**, frozen sanitizers matching raw zeros, worst mix score 0.524300 versus threshold 0.557099 (gap 0.032798). Those seeds are spent. Do not rerun looking for zero. Mix is not product-authorized. Do not generate `950000`.
 - Recorded `cycle8-mix-publishability-v1` after merging that freeze onto `main`. Product hardening on that report: software compatibility PASS on the UTF-8 product surface (Latin-1/ASCII/cp1252 unsupported; visible-projection search; raw codepoint search is not the product API). Sanitizer weaknesses still FAIL; assigned-Unicode feasibility and the width-0 closed set found no stronger Priority-Zero invisible mechanism. All 13 enclosing marks change Chromium `pre` pixels. Cross-detector generalization PASSes on Hugging Face nine-key GPT-2 Weighted Mean 0/192 plus independent Google `synthid-text` 30-key GPT-2 mix **0/192** (identity WM 189/192). DistilGPT2 n=16 is HYPOTHESIS second-model transfer (identity 16/16, mix 0/16), not confirmation-scale. Mean versus Weighted Mean on the same GPT-2 Hugging Face adapter remains HYPOTHESIS. Mix is not product-publishable. Tag `v0.3.0` is not retagged.
 - Cycle 8 H12 control-code research: DEL and C1 except NEXT LINE survive Mn-strip, default-ignorable-strip, Cf-strip, NFC/NFKC/NFKD, and frozen Cycle 6/7 sanitizers while keeping exact visible projection. Chromium `pre` pixels are host-dependent (research host matched; GitHub Actions Chromium rejected the full apply). Seen DeepMind 30-key diagnostic rescore of seed `920000` n=16 is control-mix **0/16** WM with identity **16/16**. Independent reserved seed `1100000` n=16 is control-mix **0/16** WM with identity **15/16**. This is a new `Cc` class, not a mix sanitizer PASS. Public CLI stays empty. Do not generate `950000`.

Subject: [PATCH 08/12] Record H14 extended sanitizer classes without product
 authorization.

Mc, NFKC-stable Lm, designed blanks, Hangul filler sequences, and
font-metric empty glyphs were measured. None are simultaneously
sanitizer-surviving, Chromium-portable, ordinary plain text, and
Priority-Zero safe. Mix sanitizer stays FAIL. The public CLI stays empty.

+- Hangul jamo fillers U+115F+U+1160 and Hangul filler U+3164 are default-ignorable and die to default-ignorable-strip.
+- NBSP, U+02B0, and U+FF9E/U+FF9F die to NFKC.
+- DejaVu Sans Mono has no sanitizer-surviving simple empty zero-advance glyph.
+- Chromium `pre` pixels: Mc, Lm, designed blanks, PUA, noncharacters, and layout separators `REJECTED`. CGJ remains pixel-equal and sanitizer-fragile. The only sanitizer-surviving pixel-equal probes on this host were `Cc` (DEL, NUL, CSI-filtered C1), which H12 already recorded as host-dependent and not ordinary text.

Subject: [PATCH 12/12] Record H15 sequence sanitizer classes without product
 authorization.

Grapheme prepend and joining connectors survive the required sanitizers and change Chromium pixels. Hangul L plus V dies to NFC or NFKD. Bidi wraps and partial remainders collapse to Cf or H12. Mix sanitizer stays FAIL.

+
+Status: `VERIFIED` as a negative sequence-level extension of H14. Not product authorization. Mix sanitizer robustness stays **FAIL**.
+
+This folder records local research that did not repeat assigned width-0 enumeration or the H14 single-codepoint Mc/Lm/blank sweep. It measures multi-codepoint sequences, grapheme prepend, joining, Hangul composition, bidi wraps, ISO-6429 escapes, partial-sanitizer remainders, and DejaVu Sans Mono GSUB ligatures.

+## What was measured
+
+- Thirteen UAX #29 prepend letters survive the required sanitizer bundle. Chromium `pre` rejects Malayalam Dot Reph, Sharada jihvamuliya, Zanabazar RA, and Kawi repha in front of Latin `I`.
+- Arabic tatweel, Nko lajanyalan, Mongolian nirugu, and character tie survive those sanitizers and change Chromium `pre` pixels in Latin. ZWJ/ZWNJ die to Cf-strip.
+- Hangul L plus V jamo NFC-compose, so NFC rewrites the sequence. The composed syllable NFKD-decomposes, so NFKD rewrites that form. Neither representation survives the required bundle.
+- ASCII plus sanitizer-surviving `Mc` does not NFC-compose.
+- Matched LRI/FSI plus PDI around LTR English is pixel-equal on this Chromium host and dies to Cf-strip and default-ignorable-strip. RLI and RLO wraps change pixels.
+- 7-bit ESC CSI sequences survive the sanitizer bundle because they are `Cc` plus ASCII. Chromium `pre` does not interpret them; the parameter characters stay visible.
+- Mix plus DEL stays pixel-equal here. Mn-strip leaves DEL. That remainder is the H12 `Cc` class.
+- DejaVu Sans Mono has no sanitizer-surviving zero-advance mapped glyph, including composites. Latin extra-component GSUB ligatures are discretionary `fi`/`fl` to compatibility characters that die to NFKC. Chromium `pre` does not apply that ligature: CGJ between `f` and `i` in `affirm` is pixel-equal.
+
+No measured sequence class is simultaneously sanitizer-surviving, Chromium-portable, ordinary plain text, and Priority-Zero safe.
+
+Spec: `specs/cycle8/fuckmark-cycle8-post-sanitizer-sequences-v1.json`.
+
+Do not generate `950000`. Do not retune spent confirmation seeds `830000` / `840000` / `850000`.
