+# anima-earned-datascale — H_9968 natural-corpus operator supply vs DATA scale
+
+The **top-rung fixed-length in-band corpus** for anima hypothesis **H_9968**: does the natural-corpus
+supply of a transferable recombination operator (negation flips sentiment polarity independent of the
+stem) grow with **data scale**, with sentence **length held fixed**?
+
+This is the p9 "one unopened cell" screener corpus, measured by the certified `anima-py evaluate --earned`
+instrument (corpus-statistics, never touches a trained model = the SUPPLY upper bound). DIRECTIONAL
+screener, never cemented.
+
+## Provenance
+- **Source**: [`fancyzhx/amazon_polarity`](https://huggingface.co/datasets/fancyzhx/amazon_polarity)
+  (3.6M human-labeled English customer reviews; star rating is the label, OUTSIDE the token stream).
+- **Filter (row-selection only, corpus-prep — NOT an estimator change)**: keep rows whose whitespace
+  token count is in the **frozen band 20–50 tokens** (overlaps SST-2's long tercile, where the
+  matched-length +0.007 baseline was read). This holds length — the dominant driver of the EN–KO gap
+  (H_9951) — constant across every future size rung.
+- **Result**: **1,230,238** in-band rows from 3,600,000 train rows.
+
+## Schema (`--earned` format: `text<TAB>B<TAB>T`)
+- `text` — the review body (tabs/newlines flattened to spaces).
+- `B` — free-negation bit: 1 if the text contains a free/pre-posed negator from the closed set
+  `{not, no, never, none, nothing, nobody, nowhere, neither, nor, without}` or an `n't` clitic, else 0.
+  (Same closed set as the EN FREE arm, `build_morph_split.py`.) **B=1 rate = 0.5028.**
+- `T` — Amazon star label binarized (1–2 → 0 negative, 4–5 → 1 positive). **T=1 rate = 0.5462.**
+
+## Integrity
+- `amazon_inband_full.tsv` — **sha256 `ed326109ac05eaf5307e4d0409d22ead3183392f001f770aac3ebbfcd0ae6ce0`**,
+  231,743,573 bytes, 1,230,238 rows. (HF-backup decidability is by sha256, not by name.)
+- `build_amazon_inband.py` — the exact deterministic builder (fetch → band filter → B/T emit).
+
+## How it is read (H_9968, decision table frozen before any number)
+Run `anima-py evaluate --earned amazon_inband_full.tsv`. This is the **TOP-rung ABORT gate**:
+- EARNED ≤ +0.03 with all three gates (G-ALIVE / G-PEDESTAL / G-POWER) green → **CLOSED**: the wall is
+  data-scale-invariant over the whole labeled-natural range.
+- EARNED > +0.03 → build the nested size ladder (30k → 100k → 300k → 1M → all) to locate where it climbs.
+
+Baseline: at matched length both English and Korean sit at ~+0.007 nats = 0.13% of the planted XBIND
+ruler (+5.29653). The claim this corpus can support is the SLOPE over the labeled-natural range; the
+10^12 LLM regime is unlabeled and this label-dependent instrument can never reach it.
