| # bind evolution — a falsification timeline
|
|
|
| **Research in progress. This repo is a narrative and navigation hub — not a leaderboard showcase, and not a
|
| citation target for any single result.** To cite a result, cite the member repo that carries it, pinned to a
|
| commit SHA (see [How to cite](#how-to-cite)).
|
|
|
| This is the research log of a small-model architecture line ("bind") for **compositional state tracking**
|
| at BabyLM 2026 Strict-Small scale (~24M params, 10M-word training corpus), told the only way we trust: as a
|
| sequence of **pre-registered questions, frozen verdicts, and honest refutations — including refutations of
|
| our own published results**. Every generation below either falsified its predecessor's headline claim or
|
| was itself falsified by a frozen criterion. The value of the line is not any single score; it is that each
|
| verdict — positive or null — forced a sharper next question.
|
|
|
| Ground rules that hold throughout:
|
|
|
| - **Frozen verdicts stand.** A pre-registered NULL is never re-labeled PASS, even when a post-hoc autopsy
|
| finds the criterion itself was flawed.
|
| - **We audit our own wins adversarially.** The strongest refutation in this log was performed by us, on our
|
| own already-public result.
|
| - **Negative results are published at the same resolution as positive ones.**
|
|
|
| ## What each test asked, why it was run, and what it buys — on one 8 GB laptop GPU
|
|
|
| Every experiment in this program ran on a **single RTX 4060 Laptop GPU (8 GB)**. That constraint
|
| shaped everything: single seeds where five were wanted, 30M-token budgets where the baselines got
|
| 150M, a serial queue where a lab would fan out overnight, and one scale scan that costs ~48
|
| wall-clock hours here versus a fraction of that on a modern training node. Here is what each test
|
| asked, why, and what its answer unlocks.
|
|
|
| **1. Does the headline result replicate?** A single-seed result is an anecdote. The frozen
|
| procedure was re-run on two untouched seeds: **93.96 / 94.12 / 94.22** — a 0.26-point spread
|
| across three seeds. The transfer replicates; "provisional" was removed. *Unlocks:* the result is
|
| load-bearing enough to build on.
|
|
|
| **2. Is the advantage the architecture's — or just the training data's?** Any model can look good
|
| on the diet built for it, so a standard attention-only transformer was trained on the *identical*
|
| synthetic diet and scored on the same items. On the subset where state tracking is actually
|
| required it **floors at chance (23.2%)** while the binding model scores **92.6%** there. *Unlocks:*
|
| the advantage is an architectural asset, worth carrying to scale — not a data artifact.
|
|
|
| **3. Does the mechanism survive real language in the diet?** A mechanism that only works on a pure
|
| synthetic diet is a lab curiosity. Diluted to 35% of a mixed diet (65% natural text, same total
|
| budget), the mechanism **held — 94.54%, slightly above the pure-diet run** — and the model's
|
| general grammar score landed 0.08 points below a frozen "no-tax" line while training on **5× less
|
| data than the baselines**. *Unlocks:* full-budget mixed training is the single most obvious next
|
| run, and it is purely compute-bound.
|
|
|
| **4. Does it already transfer to natural-language reference tracking?** The endgame is real
|
| language, so the gap was measured instead of assumed: pre-registered **NULL**, and precisely
|
| diagnostic — the mechanism's readout literally never fires on natural text. The gap is a **missing
|
| interface, not a disproven mechanism**. *Unlocks:* the bridge to natural text is now a concrete, bounded workstream rather than a hope.
|
|
|
| **5. Can the training scaffold be removed — or replaced by signals raw text can provide?**
|
| *(answered 2026-07-17 — in halves.)* The recipe leans on training supervision the real world doesn't
|
| hand out, so two pre-registered arms asked whether each supervision channel can be dropped; frozen
|
| bands, NULL as the default prediction — and neither arm landed on the default. **One channel:
|
| retained.** Dropping that supervision entirely holds the result —
|
| pooled **94.12\%** against a frozen retention line of 88.96, statistically indistinguishable from
|
| the original (93.96), with the shortcut-unsolvable subset at 92.6\%, empty-container items at
|
| 97.4\%, and a routing gap of 0.000. **The other channel: partial.** Removing it costs measurably —
|
| pooled **81.50\%**, well above the frozen collapse line (59.4, the audited shortcut ceiling) but
|
| below retention; the mechanism's gain survives removal (77.6\% on the shortcut-unsolvable items),
|
| routing stays intact, and it degrades gracefully rather than collapsing the result. *Unlocks:* the supervision question splits cleanly — one channel is already
|
| corpus-derivable, and the other is now a measured cost curve instead of an unknown.
|
|
|
| **6. Will the mechanism emerge on its own when the data demands it?** *(answered 2026-07-17.)* The
|
| deepest question in the line: the mechanism was forced by construction — would training pressure
|
| alone produce it? A standard architecture was trained on a corpus engineered to strip the shortcut
|
| reward (so the only way to lower the loss is to grow the real parse), and on a matched corpus that
|
| leaves the shortcut in. **Frozen verdict: neither learned it** — both floor on the
|
| mechanism-requiring subset (~0.14, below chance) while the forced mechanism scores 0.92 on the
|
| identical test. Removing the shortcut-solvable pressure, under a generous budget, does **not** rescue
|
| learning: pressure is refuted as a *sufficient* cause — the mechanism can be forced by
|
| construction, but training pressure alone does not induce it. This is a publishable negative and a
|
| precise one: it bounds where emergence does and does not happen under a generous budget, rather
|
| than leaving "emergence" an open hope.
|
|
|
| **7. Does parameter scale alone dissolve the gap?** *(resolved 2026-07-21 — the most
|
| compute-starved experiment here.)* Re-trained across a ~6× parameter ladder (24M → 145M), the
|
| standard control architectures stayed on their floor on **every** deep rung at **every** level:
|
| none of the claim-bearing deep cells crossed the bar (up to 10× the campaign training budget at
|
| the smallest and largest levels, 3.3× at the two middle levels).
|
| Scale alone does not buy this capability — the form change is principle-grade, not small-model
|
| sample efficiency. The controls neither climb toward the threshold nor decay toward chance as they
|
| grow; they sit on a fixed, scale-invariant plateau. The claim stays bounded to the tested
|
| budget × scale box, with no extrapolation to unlimited parameters. (The largest level was measured
|
| at a matched 145M configuration, disclosed; the span is stated as ~6×.)
|
|
|
| ### The ask
|
|
|
| The methodology is the guarantee: criteria freeze before data exists, NULLs are published at the
|
| same resolution as wins, and the strongest refutation in this log was performed by us on our own
|
| already-public result. Compute given to this program is not spent chasing a leaderboard number —
|
| it is spent buying **frozen answers**, at a far higher iteration rate than this hardware allows.
|
| H100/H200-class hardware would turn multi-day scans like this one into afternoons, single seeds into
|
| five-seed ladders everywhere, the 30M-token stress tests into full-budget runs, and the bridge
|
| program (question 4) plus the emergence program (question 6) into a serious entry for
|
| higher-budget tracks and the 2027 cycle, where we aim to place.
|
|
|
| To say it plainly: everything in this log — every frozen verdict, every replication, every
|
| control — was asked and answered on **one RTX 4060 laptop GPU**. We are proud of what that card
|
| has managed to answer, and we sincerely hope that one day the right connection brings better
|
| equipment within reach, so that more of these questions — and harder ones — can be attempted
|
| properly. If this log reads to you like a program worth equipping, we would be glad to hear
|
| from you.
|
|
|
| ## The timeline
|
|
|
| ### Stage 1 — bind1: the win we refuted ourselves
|
|
|
| Our official BabyLM 2026 strict-small entry (~24M params, an iterative role-binding loop) showed what
|
| looked like the paper's key result: **entity tracking 39.55 vs 27.82** for the matched monolith (+11.7
|
| points, single seed), alongside BLiMP 65.5 vs the GPT-2 baseline 65.1. We flagged it at submission time as
|
| "the key result to replicate, not a settled fact" — and then we replicated adversarially instead of
|
| celebrating.
|
|
|
| The audit finding: **the entity-tracking lead was not tracking.** In the benchmark's item pool, "nothing."
|
| never appears as a distractor (0 of 9,483 items) — whenever it is among the options it is the answer — and
|
| completion scoring structurally favors it. Counterfactual probes showed that *no* model in an 11-model,
|
| multi-seed grid could actually distinguish empty from non-empty containers (discrimination ≈ coin-flip,
|
| AUC 0.47–0.58); on non-"nothing" items every model, every seed, sat at chance. The entire ablation gradient
|
| that looked like a mechanism story was the gradient of a state-blind "nothing." completion prior. Under the
|
| leaderboard's corrected scoring standard (nothing-gold items removed), the lead disappears.
|
|
|
| Both scorings are published side-by-side on the public bind1 model card (repo map below). This
|
| refutation-of-our-own-result is the credibility opener of the whole line: it is why you can trust the
|
| verdicts that follow.
|
|
|
| ### Stage 2 — the curriculum duel: a null that indicted the exam, not the architecture
|
|
|
| A pre-registered curriculum duel asked whether the binding architecture out-learns a matched monolith on an
|
| in-context binding curriculum. Frozen verdict: **NULL** — but of a specific, diagnostic kind: *both* arms
|
| stayed flat near floor across all 12 checkpoints through 50M tokens (endpoint 0.1875 vs 0.1842). Under the
|
| frozen decision grid this lands in the "exam/scale problem" cell: an exam neither arm can learn
|
| discriminates nothing about architecture. We recorded it as an **exam-design artifact** and drew the
|
| obvious lesson — before asking *who learns faster*, first build an exam that is demonstrably learnable.
|
| That lesson directly shaped the next two generations.
|
|
|
| ### Stage 3 — bind2_0: the mechanism works; the transfer doesn't ("no tax, no win")
|
|
|
| bind2_0 combines delta-rule fast-weight memory with a **forced bottleneck**: attention is chunk-local, so
|
| cross-chunk information can only flow through a recurrent state. Three results, all kept:
|
|
|
| 1. **Direct-task training works.** On a purpose-built synthetic swap-tracking task (n=800 per eval, 5-way,
|
| chance 0.20), bind2_0 reaches **0.9988 accuracy** while its matched controls (monolith, bind1-style
|
| loop, no-binding control) sit at **0.2125 / 0.1938 / 0.1938** — with a sharp grokking transition between
|
| 5M and 10M training tokens (0.179 → 0.969 → 0.996). Learnable exam: achieved.
|
| 2. **It does not emerge for free.** Trained as a plain LM on the real BabyLM strict-small corpus, the
|
| architecture showed **no emergent zero-shot state-tracking advantage** (on a 60-probe test with chance
|
| 0.50, no model — ours or baseline — beat chance).
|
| 3. **No general-language tax.** On the official zero-shot evaluation it is **statistically tied with the
|
| matched baselines**, slightly above the GPT-2 baseline on BLiMP (66.11 at 23.9M params vs 65.08).
|
|
|
| Honest summary: **"no tax, no win."** Mechanism capability and benchmark transfer are *separate questions*,
|
| and conflating them is how fields fool themselves. What this stage forced next: split the confound — first
|
| prove the mechanism is *causally real at depth* under a pre-registered gate, separately from transfer.
|
|
|
| Weights and code for this stage:
|
| [`SecludedCorner/bind2_0`](https://huggingface.co/SecludedCorner/bind2_0)
|
| (main = 23.9M build; branch `27m` = 27M build).
|
|
|
| ### Stage 4 — bind2_1: a NULL that stands, a causal result that survives, and a new finding
|
|
|
| The successor mechanism (weights/code not released — see below) was tested the hard way: a **10-arm
|
| campaign, 5 seeds per arm, with thresholds and the judgment script frozen before any data existed**. The
|
| frozen gate was an AND over five criteria. What happened is the most instructive verdict in this log:
|
|
|
| - **Discrimination passed.** The full system scored **85.83** (pooled deep-rung accuracy) against **every**
|
| control arm sitting at chance (≈16.5–17.5, chance 16.98) — a ~69-point margin over each of seven learned
|
| controls, on all 5 seeds, against a pre-registered minimum effect of 5 points. A scrambled negative
|
| control scored *below* chance (12.67), and an oracle upper bound scored 99.92. An audited shortcut
|
| ceiling (the best any state-blind strategy could reach) was ≤19.7 pooled; the system exceeds it by ~66
|
| points.
|
| - **Causality passed.** Lesioning the mechanism's state pathway removes **99.3%** of the deep-rung
|
| advantage while leaving non-query language modeling flat; interchange patching flips **96.4%** of answers
|
| to the donor context's holder, with residual specificity 1.0. The deep-rung behavior is carried by the
|
| mechanism — necessarily and sufficiently.
|
| - **Criterion C failed → verdict NULL.** C required the depth-interaction margin to hold or grow with
|
| depth; the observed margins shrink (73.3 → 74.5 → 66.5 → 60.3 across the four deep rungs), which the
|
| pre-registration had labeled a "bypass" signal. **The frozen verdict is NULL and it stands permanently.**
|
| - **The autopsy — recorded, not used to overturn.** Adversarial post-hoc analysis showed criterion C was
|
| **ceiling-confounded**: because chance itself falls with depth, only a near-lossless mechanism (like the
|
| oracle, which passes C) *could* pass; a system starting at 96% has nowhere to grow its shallow margin.
|
| This is a design-time specification error and we record it as exactly that. The "bypass" *interpretation*
|
| of the NULL is, separately, refuted by the causal results: a bypassed module cannot carry 99.3% of the
|
| effect, and the deepest rung (72.8) sits ~57 points above the audited shortcut ceiling (≤15.5).
|
| - **The real finding: limited effective depth.** The mechanism's engagement decays gracefully with depth
|
| (≈95% → 69%) while the oracle stays ≈100% — so depth-robust binding is achievable on this task and the
|
| learned mechanism does not fully achieve it. That gap is a concrete architectural target, not a
|
| rhetorical one.
|
|
|
| **Why there is no bind2_1 repo:** the headline number is a teacher-forced readout on a synthetic diagnostic
|
| corpus (not BabyLM data), and a standard free-running export does not reproduce it. Publishing weights that
|
| cannot reproduce their own headline would be misleading, so this stage ships as numbers-and-narrative only.
|
| What is withheld is tooling and weights, not results — the numbers reported here are complete.
|
|
|
| Because the corrected depth criterion (C′) was formulated after seeing the data, it cannot be scored on
|
| that data as anything but exploratory. So C′ was **frozen on 2026-07-15, before touching the five held-back
|
| seeds**, and the confirmatory rerun on those untouched seeds landed the same day: **CONFIRMATORY PASS.**
|
| Per-rung margins on the fresh seeds — 73.3 / 74.6 / 66.9 / 59.4 points — replicate the original seeds
|
| almost exactly; the deepest rung scores 72.7 against a 31.0 shortcut bar; and the causal lesion battery
|
| replicates on all five unseen-seed checkpoints (99.30% of the deep advantage removed by the state lesion).
|
| One procedural note, disclosed in full: the judgment script as originally frozen demanded control arms the
|
| confirmatory design never scheduled and exited without scoring; that output is preserved untouched, and the
|
| verdict above comes from a plumbing-fixed variant whose criteria are byte-identical to the frozen ones,
|
| adversarially reviewed before unblinding, with the full evidence chain on record internally. The
|
| discrimination criterion was inherited from the original seeds, not re-measured. The seeds-0-4 NULL stands
|
| unchanged.
|
|
|
| ### Stage 5 — bind2_1e: the mechanism passes the official exam (single seed, provisional)
|
|
|
| The transfer question bind2_0 failed ("no tax, no win") could now be asked properly: take the
|
| causally-verified binding mechanism, train it on a synthetic box-tracking corpus whose answer statistics
|
| are **distribution-matched to the official entity-tracking benchmark**, and score it on the official items with **fully learned routing** — no oracle assistance at test time.
|
|
|
| Everything was pre-registered and frozen before the run: the corpus ruling, the success/null bands, the
|
| shortcut-decomposition gates, the abort rules. Default prediction: NULL.
|
|
|
| Result (2026-07-15), one shot, first read final: **93.96% pooled** on the two in-scope official subsets
|
| (6,259 items; chance 20%; every earlier model in this program — and the published baselines — sits at
|
| ≈19–21% on this benchmark). The regular subset scores **99.05% with zero decay across operation depth**
|
| (99.4% at the deepest tier); the contents-move subset scores **88.80%** with graceful depth decay. The
|
| routing fear died completely: the learned router matches oracle-hinted routing to the third decimal
|
| (transfer gap 0.000).
|
|
|
| The credibility core is the pre-registered decomposition. The benchmark's strongest audited shortcut ("the
|
| last-touched box is the answer") can solve ~59% of items; on the **2,550 items that shortcut cannot solve,
|
| the model scores 92.4%** — and 96/92/92/92/81% across operation depths 1–5. Empty-box golds (the classic
|
| prior-abuse trap from Stage 1) score **97.6%**, with a perfect 100% on the regular subset. The verdict
|
| label, per the frozen bands: **MECHANISM-TRANSFER — provisional, single seed.**
|
|
|
| What this is *not*, stated plainly:
|
|
|
| - **Single seed means exactly that: provisional until replicated.**
|
| - **Subset scope:** the score covers the regular and contents-move subsets only — 6,259 of the benchmark's
|
| 9,483 items; the ambiguous-reference subset was excluded by the frozen pre-registration as outside
|
| mechanism scope.
|
| - **This is a mechanism-transfer demonstration, not a general language model.** The model was trained only
|
| on synthetic box-tracking text; every other suite in the official evaluation is expected to sit at chance
|
| by design, and no claim is made there.
|
| - **The natural-diet baselines are diet-confounded as an architecture comparison.** Their chance-level
|
| scores come from natural-text training; the matched-diet architecture attribution rests on the bind2_1
|
| campaign's seven matched controls (Stage 4) plus the dedicated matched-diet control reported just below.
|
|
|
| Nothing from this stage is downloadable at this point: the weights, code, configuration, and the
|
| corpus/generator tooling are all withheld at this stage. The frozen pre-registration, the decomposition,
|
| and the per-item results are on record internally; the numbers reported here are complete.
|
|
|
| **Update (2026-07-17) — three pre-registered follow-ups, all resolved in the mechanism's favour.** Each
|
| froze its bands before its run; the results:
|
|
|
| - **Seed replication (now n = 3).** The frozen procedure re-ran on two untouched seeds: pooled **94.12%**
|
| and **94.22%**, against the original **93.96%** — a spread of 0.26 points across three seeds, with the
|
| shortcut-unsolvable subsets and empty-box golds replicating in lockstep. The "provisional — single seed"
|
| qualifier is **removed**: the transfer replicates.
|
| - **Matched-diet control (the diet-confound, closed).** A standard attention-only transformer trained on the
|
| *identical* box-tracking diet (same token budget, single seed) scores pooled **50.6%** — but on the
|
| pre-registered decisive subset, the items the shortcut cannot solve, it scores **23.2% ≈ chance (20%)**,
|
| versus this model's **92.6%** on the same subset. Its overall half-score is carried entirely by the
|
| empty-box prior and the last-touch shortcut; on the items that require state tracking it floors. A standard
|
| architecture on the same diet cannot do it — the advantage is architectural, not a diet artifact.
|
| (Single seed = provisional.)
|
| - **Mixed-diet stress test.** Retrained on 35% box-tracking + 65% natural text (same 30M-token budget), the mechanism holds: pooled **94.54%** — if
|
| anything *above* the boxes-only run (report-only, single seed), all decomposition gates passed by wide
|
| margins. On this mixed diet the model also produces real (non-chance) general-language scores; its BLiMP
|
| came in at **59.92 against a pre-registered no-tax gate of 60.0** — 0.08 below the line, recorded under
|
| the frozen label **TAX-OR-BUDGET**: attribution left open between an architecture cost and the 5×-smaller
|
| token budget of this run versus the 150M-token baselines, neither claimed. A separate zero-training probe
|
| for transfer to *natural-language* reference tracking returned the pre-registered **NULL** on both primary
|
| subjects — expected, since the mechanism's readout is inert on those inputs; recorded as no evidence, not
|
| as a mechanism failure.
|
|
|
| ### Stage 6 — where the line is now
|
|
|
| Current focus: consolidating the replicated transfer result and its controls.
|
|
|
| ## The dual-verdict structure, stated explicitly
|
|
|
| Two verdicts exist for bind2_1 and they answer **different questions**. They are never merged:
|
|
|
| 1. **The original pre-registered verdict is NULL, permanently.** Criteria and judgment were frozen before
|
| data; criterion C failed; the AND-gate returns NULL. Re-labeling it PASS after seeing the data would be
|
| criterion-shopping, and the entire point of pre-registration is to make that impossible. The autopsy
|
| that found criterion C ceiling-confounded is *recorded alongside* the verdict; it does not modify it.
|
| 2. **The corrected-criterion confirmatory run is a separate, second question.** C′ (per-rung margin above
|
| the pre-registered minimum effect AND deepest-rung accuracy far above the audited shortcut ceiling) was
|
| frozen on 2026-07-15 **before** the five backup seeds were touched; those seeds played no role in
|
| designing C′. Its result (2026-07-15): **CONFIRMATORY PASS** — per-rung margins 73.3/74.6/66.9/59.4
|
| points on the fresh seeds, deepest rung 72.7 vs the 31.0 shortcut bar, causal battery replicated on all
|
| five unseen-seed checkpoints. It answers "does the corrected criterion hold on fresh seeds?" (yes) — it
|
| does not, and cannot, retroactively change verdict #1.
|

| Notes (from the frozen source): pooled deep = micro-average over R3–R6, the frozen primary endpoint;
|
| pre-registered minimum effect (SESOI) = 5.0 pp on pooled deep; shallow rungs R0–R2 are shortcut-reachable
|
| by design (claim-ineligible) and intentionally not tabled.
|
|
|
| Causal results (frozen gate, criterion B): state-lesion kill = 99.3% of deep-rung advantage with non-query
|
| perplexity flat; interchange flip = 96.4%; residual specificity = 1.0; all 5 seeds pass.
|
|
|
| Depth margins vs learned control F, the pre-registered reference control (criterion C, failed):
|
| R3 73.3 / R4 74.5 / R5 66.5 / R6 60.3.

|
|
| - [a] Server-verified 2026-07-10; the leaderboard "Reading" aggregate is 6.46 (self-paced 3.34 /
|
| eye-tracking 9.59); the 9.59 cell above is the eye-tracking component as tabled in the source.
|
| - [b] Local run of the official strict-small zero-shot pipeline, single seed, **not** submitted to the
|
| leaderboard; tasks the local pipeline cannot produce remain pending.
|
| - [c] The paper-baseline Entity 27.82 uses the **old pre-filter** entity standard; the same checkpoint
|
| re-scored under the post-filter standard measures 19.24 — the two Entity columns are not directly
|
| comparable across scoring standards. (This scoring change is exactly the bind1 refutation story in
|
| Stage 1.)
|
| - Reference point: GPT-2 strict-small baseline BLiMP = 65.08.
|
| - [d] bind2_1e is a **mechanism-transfer probe, not a general LM entry**: trained solely on a synthetic
|
| distribution-matched box-tracking corpus (30M tokens, single seed, free routing at test). Its Entity cell
|
| covers the regular+move_contents subsets only (6,259/9,483 items; the ambiguous-reference subset is
|
| excluded by the frozen pre-registration — outside mechanism scope); other suites are expected ≈ chance
|
| **by design** and are not measured or claimed ("n/a"). Pre-registered decomposition: shortcut-unsolvable
|
| subset 92.39, empty-box gold 97.55, learned-routing gap 0.000 (the decomposition and per-item results are
|
| on record internally; withheld at this stage). Same-scorer baseline reruns (same subsets, same script)
|
| will be tabled as they land.
|
| - [e] bind2_1e-mixed = the same architecture retrained on 35% box-tracking + 65% natural text (30M tokens,
|
| single seed), so its BLiMP/supp/EWoK/COMPS cells are real measurements. BLiMP 59.92 sits 0.08 below the
|
| frozen no-tax gate of 60.0 → recorded **TAX-OR-BUDGET**, attribution open (the natural-text baselines
|
| above trained on 150M tokens — 5× this run's budget); neither "tax" nor "no tax" is claimed. The Entity
|
| cell 94.54 is the **mechanism-caliber** one-shot score (regular+move_contents subsets, per-item records);
|
| under the **official-pipeline caliber** — the official 2026-07-12 exam, all three subsets including
|
| ambiguous-reference — the same run measures **69.95** on the official exam, versus the natural-text
|
| baseline's **19.24** (≈ chance). The two calibers are materially different and are never interchangeable. Decomposition:
|
| shortcut-unsolvable 92.55/89.92 (two frozen conventions), empty-box gold 98.94, routing gap 0.000.
|
| - [f] mono matched-diet control = a standard attention-only transformer trained on the **identical**
|
| box-tracking diet (same budget, single seed). Pooled 50.57, but on the shortcut-unsolvable subset it
|
| scores **23.22 ≈ chance (20)** versus bind2_1e's 92.55 on the same subset; its overall half-score is
|
| carried by the empty-box prior (nothing-gold 99.89) and the last-touch shortcut. This closes the
|
| architecture-vs-diet confound: a standard architecture on the same diet floors on the mechanism-requiring
|
| items. Single seed = provisional.
|
| - Under the current (filtered) Entity standard, entity tracking is ~chance for all natural-diet grid models
|
| — the spread across architectures on the comparable local-zero-shot rows is within single-seed noise; no
|
| architecture wins the official exam from natural-text training alone, which is exactly the Stage-3
|
| "no tax, no win" point. The bind2_1e rows are a different kind of entry — a diet-matched transfer probe
|
| (see [d]/[e] and Stage 5) — and do not overturn that point.

|
|
|
| Cite **member repos, not this hub**, and always pin to a 40-character commit SHA
|
| (`revision="<full-sha>"` in `from_pretrained`, or the `/tree/<sha>` URL form). The authoritative SHA for
|
| each published artifact is stamped on that repo's card as a dated addendum at publish time.
|
| This hub's prose may be updated as research progresses (updates are dated); member-repo cards are frozen at
|
| publish, which is why they — at a pinned SHA — are the citation targets.
