Subsequent full-sequence regression replay needs neither the historical full-vocabulary probability vector nor a softmax normalizer.

Compression compares full q plus actions/mask against the complete numeric moment record, excluding string metadata. These are **not whole-model, GPU, or end-to-end speedups**. A vocabulary smaller than the feature dimension can make the moment record larger. + +Additional results: + +- **248 CPU tests pass**, covering gradient equivalence, covariance, masking, transport, mutation rejection, sequence-view independence, rollback and publication boundaries. +- Safe stratification gives **293.77x** lower conditional logit-correction variance than equal-budget IID on the peaked fixture, versus EVE's **267.23x** on the same distribution.

Version: `2.0.0`. The annotated source is the complete API specification; this guide gives shape and validity contracts. Tests are executable examples. + +## Exact moment replay + +`FeatureBank(features, bias=None)` takes fixed finite floating tensors `[V,R]` and `[V]`, owns detached copies, and fingerprints their bytes. It refuses trainable inputs unless the caller intentionally detaches them. The immutable feature basis is not the same as the effective output head: `x_theta = A_theta h_theta + c_theta` may train freely inside the fixed vocabulary span. Arbitrary new feature directions, moving tied embeddings and nonlinear post-projection logits are not supported by this identity. + +`capture_moments(q, actions, mask, bank, sampler_version=..., context_id=...)` requires actual historical sampling probabilities `[B,T,V]`, int64 actions `[B,T]` in historical support, and a boolean mask. It records feature mean `[B,T,R]`, bias mean, sampled-action log q, mean log q, actions and mask, plus identifiers. Historical q is detached. Small rounding-scale normalization is allowed; smoothing/truncating a different distribution is forbidden. Capture costs a vocabulary pass and a matrix-moment reduction. + +`MomentBatch.verify(bank, context_id=None, full=False)` validates dimensions, support metadata, finite values, bank identity and mutation counters. `full=True` hashes bytes too. A context label is not independently authenticated: the caller must retain and bind the exact original context and reward. `save/load` uses numeric NPZ, never pickle. `.to(device)` verifies the source record's digest before copying. + +`moment_sequence_loss(latent, record, bank, rewards, beta=0.1, temperature=1.0, outer_weights=None, normalizer=None)` requires latent `[B,T,R]`, terminal rewards `[B]`, beta > 0, fixed positive temperature and complete-response masks. It returns `(loss, diagnostics)`. It evaluates a genuine squared sequence-regression objective, not the numerically equal value of the older stop-gradient surrogate: gradients, not those two displayed scalars, are the equivalence target. There is no vocabulary-sized replay-head operation or normalizer pass. Backbone, input-embedding gradients and optimizer work remain. + +`moment_token_loss(...)` preserves the exact full token sample-gradient but still computes the current action probability with a chunked forward normalizer. Do not call it normalization-free training. + +`moment_dimension(features)` reports a numerical affine-rank diagnostic. The paper's exact-rank theorem concerns linear summaries preserving all feature expectations; it is not a claim that the whole replay record is information-theoretically minimal among arbitrary encodings. + +## Checked feature-bank transport + +`AffineBankTransport(source, target, matrix, offset, bias_direction=None, bias_offset=0)` checks the entire bank relation once: `phi_new = phi_old @ matrix + offset`, `b_new = b_old + phi_old @ bias_direction + bias_offset`. Shapes are `[R_old,R_new]`, `[R_new]`, `[R_old]`, scalar. Banks must share token identity, vocabulary size and device. The equality test is exact on the computed floating arrays, with ordinary subsequent arithmetic roundoff. Approximate relations are not silently accepted. + +`transport.apply(record)` then transforms only the stored moments; it needs no full historical q. It returns a new bank-tagged record with unchanged actual historical action log q, entropy statistic, actions and context label. Target directions outside the certified affine image require retained full q or fresh collection. This map preserves the target objective, not the old policy or every possible downstream task. + +## Correction samplers + +`draw_correction(q, mask, budget, mode, generator=...)` retains IID, safe and logit-trace head/tail comparators. `exact_correction(q, mask)` enumerates all positive probability entries. + +`stratified_correction(q, mask, budget=32, head='safe', generator=...)` retains the same head and uses independent equal-mass inverse-CDF tail strata. Its `Correction` contains IDs, weights, historical log q and mask. Weighted masses equal one per active token in real arithmetic. Fresh auxiliary draws must be conditionally independent of the already collected action and of one another at separate score sites. Positive CDF-interval collapse triggers an IID tail fallback. The `safe` covariance chain is conditional, not an end-to-end superiority theorem. The `trace` head is chosen using the old IID-tail trace, not a reoptimized stratified trace. + +`coalesce_correction(record)` merges repeated IDs without changing the weighted integral, up to floating-point arithmetic; it adds sorting overhead. `stratum_probabilities` and `stratified_trace_variance` are analytic diagnostics, not empirical learning metrics. + +## Trainable linear output-head kernels + +`centered_linear_scores(hidden, weight, actions, q=... OR ids=..., coefficients=..., bias=None, chunk_size=4096, row_chunk_size=64, temperature=1.0)` returns centered logits plus detached current action log probabilities. `hidden` is `[N,D]`, weight `[V,D]`, actions `[N]`; sampled IDs/zero-mass coefficients are `[N,K]`. It implements first-order vector–Jacobian products only. Exact mode streams q-weighted terms. Sampled mode recomputes selected activations in backward. Shared/tied output weights are tested for this general full-q route. + +`linear_token_loss(hidden[B,T,D], weight, actions, q, mask, returns, correction=None, ...)` connects that kernel to the token objective. `correction=None` is exact streaming. Supplied correction records preserve the specified sample gradient. Full q, dense output-weight gradients, optimizer state and full-vocabulary normalization are not eliminated by these kernels. + +The older `selected_linear_scores`, `selected_token_loss`, dense `token_loss`, and independent-view `sequence_loss` remain available. Sequence sampled views must be independent; reusing a view in residual and score creates a bias term. Outer weights represent fixed finite-buffer sampling corrections, not self-normalized weights. Default reduction is sum over valid tokens per response and mean over responses, not a mean over tokens. A supplied fixed normalizer supports microbatch accumulation. + +## Audits, replay and transactional updates + +`MetricSpec(name, minimum=0, maximum=1, direction=1, min_gain=0, penalty=0)` defines a bounded return, its improvement direction, a required signed gain, and any separately justified error allowance. A lower-is-better cost uses `direction=-1`; tolerating a small cost increase requires an explicitly negative `min_gain`. + +`SequentialParetoAudit(metrics, ledger, candidate_id=..., looks=(...), method='hybrid', ledger_path=None)` consumes confidence at construction. `.add(candidate[N,M], baseline[N,M], candidate_id=...)` uses fresh IID paired evaluations of a proposal held fixed during that audit. It stops at registered looks, accepts only if all lower bounds exceed margins, or remains inconclusive. Hybrid selection splits its confidence allocation between the two candidate inequalities. Candidate IDs are caller-maintained identities, not an independent proof that model bytes were held fixed. `save/load` resumes the same audit; never rewind consumed evidence or the global ledger. Concurrent writers require external locking. + +`transactional_step(model, optimizer, closure, audit)` snapshots parameters, buffers, optimizer state, parameter gradients and training-mode flags. Rejection or exception restores them. Randomness, external systems and confidence spending are not rolled back. Do not use it to undo real-world external actions. The original single-look Hoeffding `paired_gain_audit` remains available. + +Historical full-q `ReplayRecord`, `ReplayBuffer`, `collate`, finite-state quotient checks, bounded beta control and potential-baseline helpers remain. Their integrity digests do not prove truth, causal validity or future environment stability. + +## Runnable models and checkpoint loading + +`FixedSpanCausalLM` is a tiny synthetic model whose `forward` includes the trainable span adapter. `run_moment_lm` trains it with default moment replay; `dense_oracle=True` keeps q only for the reference comparison. `load_moment_model` validates numeric-only weights, expected parameter names/shapes/dtypes, the feature bank and output projection, and returns `(model, bank)` for inference. The checkpoint contains no pretrained natural-language ability and no complete optimizer/RNG resume state. + +`TinyCausalLM`, `run_tiny_lm` and `load_tiny_weights` cover the unrestricted-head token route. The optional Hugging Face adapter uses generic dense logits; its protocol is locally tested with an initialized model, not a downloaded pretrained model. Architecture-specific extraction of pretrained hidden states for optimized kernels must be integrated and validated separately. diff --git a/docs/BENCHMARKS.md b/docs/BENCHMARKS.md new file mode 100644 index 0000000000000000000000000000000000000000..1d109dddd13e940ff8bb736df41d1388098ab657 --- /dev/null +++ b/docs/BENCHMARKS.md @@ -0,0 +1,81 @@ +# Celestis-RL v2.0.0 — executed evidence + +All current measurements are in `results/celestis_v2/`.

The token can also be supplied through `HF_TOKEN` in the process environment. It is never hard-coded into the BAT, saved in JSON, bundled, or passed as a command-line token argument. The Windows BAT creates a local virtual environment, installs publication dependencies, previews the release, asks the user to type `PUBLISH`, and then uses `set /p` for a paste-enabled token prompt. The pasted token is intentionally visible, stored only in that BAT process environment, passed to Python through `HF_TOKEN`, and cleared immediately after the upload attempt. Windows execution was not tested here. + +The uploader creates a **new** repository with `exist_ok=False`, stages hash-verified bytes, and uses the documented `HfApi.upload_folder` API. Omitting `--public` makes explicit publication private. Existing repositories are not overwritten or deleted. A failed upload after repository creation can leave an empty/partial remote repository; this minimal uploader deliberately does not implement authenticated repair or automatic resume of an existing repository. It is not a claim of atomic remote publication. + +The manifest provides byte integrity, not authentication or scientific validity. The verifier's credential detector is a limited safeguard, not a comprehensive secret scanner. Review the allowlisted files before publication. The release has synthetic data and numeric demonstration weights, not user-private training data. + +## Presentation and citation + +Use title **Celestis-RL: Exact Moment Replay and Certified Score-Centered Optimization**. Describe it as an AI-assisted, CPU-tested research reference with conditional exactness and measured local benefits. Do not label it a generally superior pretrained model, an official KLPO fork, or peer-reviewed/SOTA. Keep the negative benchmark cases and explicit feature-span restriction visible. Cite `CITATION.cff`, the objective source and relevant prior methods separately. `release/artifact.json`, `research/claims.json`, `AGENTS.md` and `llms.txt` give machine-readable entry points. The publisher may add a real DOI or remote identifier only after registration. + +No remote upload occurred during this session. Only offline dry-run and mocked publication-boundary tests were executed. + + +## Local workspace files + +The uploader verifies every file declared by `release/MANIFEST.json`, but it intentionally ignores extra local files in the working tree. Extra files are **not uploaded**: publication first stages only the manifest-declared release bytes into a temporary directory. This means screenshots, notes, or a copied helper BAT cannot accidentally leak into the Hub release or cause preview verification to fail. If you want a new file published, add it intentionally and rebuild the release manifest. diff --git a/docs/LIMITATIONS.md b/docs/LIMITATIONS.md new file mode 100644 index 0000000000000000000000000000000000000000..4606f2f2cc28a3a0c9336ca7ce7515e50cbdf995 --- /dev/null +++ b/docs/LIMITATIONS.md @@ -0,0 +1,31 @@ +# Limits, counterexamples and non-claims + +## Structural restriction is real + +Moment replay is exact for logits in a fixed vocabulary feature span, including an arbitrarily trainable backbone and trainable latent/span adapter. It is not exact for arbitrary future output heads. Affine transport handles checked changes in the same represented family; adding unrelated directions needs full historical q or new data. A frozen output basis tied to a trainable input embedding is not frozen in the required sense. The general full-q kernels support trainable/tied heads but do not obtain the moment-storage benefit.

Marginal moment equality does not identify a causal environment or reconstruct a distribution. + +## Exact does not mean everything is free + +The sequence objective head has O(NR) replay work after capture, but collection still generates tokens and traverses vocabulary probabilities, moment formation costs O(NVR), the feature bank uses O(VR) global storage, and the backbone/optimizer retain their own costs. Input-embedding gradients may themselves be vocabulary-sized. Record compression is favorable when V substantially exceeds R, and can be unfavorable for small vocabularies. Full-sequence algebraic cancellation does not remove the normalizer from the token objective. + +The custom full-q kernels avoid retaining particular head activations. They still allocate working blocks and dense parameter gradients. They are first-order custom autograd paths, not general higher-order differentiation, distributed FSDP kernels or validated GPU kernels. The CPU recomputation fixture was slower, and the benchmark explicitly shows it. Chunk size, precision, architecture, bandwidth and hardware can change the tradeoff. + +## Conditional covariance is not task dominance + +Independent equal-mass stratification improves the conditional auxiliary correction covariance at a fixed head and draw count. Safe head selection extends the chain to an equal-budget IID comparator. This does not order finite-run losses, rewards, exploration, total gradient covariance when coefficients are also random, sequence-residual products or wall-clock time. Sorting and CDF processing can cost more than the saved correction noise is worth. A single shared jitter across all strata does not have the independence proof and can be worse than IID; a counterexample is tested. Finite floating-point distributions approximate real-arithmetic identities, and extreme tails may trigger fallback. + +## Confidence gates can abstain and can be slow + +Only registered bounded metrics are covered, conditional on fresh IID pairs, a fixed candidate and known valid bounds/error allowances. Unbounded real metrics require a different bound or an explicitly changed clipped objective. Repeated looks and attempts must use the persistent ledger; rolling it back or reusing the same holdout invalidates the guarantee. Zero tolerance on an exactly unchanged metric generally prevents finite-sample certification. Hybrid bounds can need more samples than Hoeffding. A non-acceptance is inconclusive evidence, not necessarily proof of harm. Single-process persistence is not a distributed transaction system. + +## Evidence and novelty boundaries + +248 CPU tests and small synthetic experiments are not a formal proof assistant certification, independent peer review, production validation or general RL benchmark. Twenty bandit seeds favor the new sampled route on average, while full correction remains better on average. The Transformer demonstration uses four finite prompts and has no generalization claim.
