Executes a caller-directed sequence of table operations in native OpenRefine and returns the transformed table together with the exported recipe. What distinguishes it from simply transforming data is the evidence: the recipe is persisted, the project is reopened, and the whole thing is replayed from the original input, with hashes reported at each stage.

Use this when an agent has an older and a newer LLM catalog snapshot and needs a deterministic migration diff before changing routing or budgets. Rows are matched by vendor plus model, id or name. The result separates added, removed and changed models and reports field-level differences for input, output and cached-input price, context window and maximum output tokens.

Applies the standard affine propagation of uncertainty: the mean goes through the transform and offset, the covariance through the transform on both sides, and the independent noise covariance is added. This is the prediction step of a Kalman filter and the workhorse of any linear error budget.

Computes the full eigendecomposition of a real symmetric operator and reports the signed eigenvalues, the orthonormal eigenvectors, and the inertia — how many eigenvalues are positive, negative and indistinguishable from zero at the stated tolerance. Two residuals are returned as evidence rather than as reassurance: how far the decomposition is from reproducing the input, and how far the eigenvectors are from being orthonormal.

Takes an OpenTofu state snapshot and a passphrase, encrypts the snapshot through the pinned OpenTofu state-encryption code, then proves the result three ways: the authorized key recovers the state with an identical semantic hash, a wrong key is rejected, and a tampered payload is rejected. What comes back is the encrypted artifact plus those proofs and the resource-instance count, never the plaintext.

Factors a matrix into rank-k left and right factors with their singular values, optionally centering the columns first, and states what the compression actually cost: the Frobenius reconstruction error against the input and the fraction of spectral energy retained. The full spectrum comes back too, so a caller can pick a different k without a second call. With centering enabled this is principal component analysis, and the column means are returned as part of the model.

Relocates a Java package across a bounded set of source files using OpenRewrite, which works on a type-attributed syntax tree rather than on text. That is the difference that matters: a textual search and replace hits strings, comments and same-named symbols from other packages, while this changes only what actually refers to the package. Both the before and after state are compiled and the result is reported, so a refactoring that breaks the build says so instead of being handed over as done.

Produces the two transforms a stochastic model normally needs from a covariance: the whitening matrix that maps correlated data to unit-variance uncorrelated data, and the coloring matrix that goes back the other way. Both are returned so the round trip is available without a second call.

Solves a bounded dense multi-output least-squares problem and returns the minimum-norm solution together with the diagnostics that say whether it can be trusted: numerical rank, the full singular value spectrum, the rank threshold actually applied, the residual, and the effective condition number. A rank-deficient system still gets an answer here, but it gets one that announces its own deficiency instead of a plausible vector with no warning attached.

National price statistics for a billing code (CPT/HCPCS/MS-DRG) from hospital price-transparency files: median and spread of payer-negotiated rates. Answers: what is a fair price for this procedure? Shape varies: a code under one billing_code_type (common case) returns the flat row shown below; a code ambiguous across types instead returns { billing_code, stats_by_type: [...] } — check for a top-level stats_by_type array to tell them apart.

Clusters a key column with native OpenRefine fingerprinting and returns a consolidation plan tied to actual row ids. The plan distinguishes the two cases that matter: rows that repeat an identical value and can simply be merged, and rows that collide on the key but disagree in other fields — those are flagged as unresolved rather than silently collapsed, because merging them would destroy information. Excluded rows and singletons are reported too, so the plan accounts for every input row.

Contact discovery audit fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.
