Retrieve up to three approved, rights-reviewed public text sources for one narrow question. Return a bounded extractive brief with exact short quotes, source links, locators, retrieval hashes and explicit unknowns. No model calls, invented answer, semantic contradiction detection, open-ended research or factual certification.

Apply the composite trapezoidal rule to 2-128 equally spaced integer samples. Returns an exact rational arithmetic result, declared units and an integrity receipt. No quadrature-error estimate or claim of an exact underlying integral. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Compare 2-20 caller-labelled observations of one claim, population and outcome. Returns opposing directions and explicitly excluded observations. No literature search, source inspection, consensus judgment or factual verification. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Check a revision handoff before reusing evidence. Compare one initial or superseding transition with its declared predecessor; return lineage inconsistencies and an integrity receipt. Does not establish authenticity, semantic equivalence or inherited review approval. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Get an inspectable exact solution to a 1-8 variable rational linear system. Returns rank, pivots, particular solution and null space; distinguishes unique, inconsistent and underdetermined systems. No floating-point conditioning or physical-model assessment. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Check citation metadata before an evidence review. Compare up to 20 declared source identities, revisions and locators; return exact mismatches and an integrity receipt. No source retrieval, passage-existence check or claim-support verification. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Check one structured public or synthetic low-stakes experiment plan for timing, comparator, outcome and analysis declarations. Returns deficiencies and an integrity receipt. No registration, trusted timestamp, prediction, power analysis or scientific validation. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Multiply or divide two seven-component SI dimension vectors and compare with the expected output dimension. No unit conversion, formula validation, scale-factor inference or physical-model certification. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Validate and normalize a JSON audit-event export before reconciliation. Check up to 100 supplied metadata events for duplicate IDs, malformed timestamps and invalid digests. Returns normalized events and an integrity receipt; no CSV parsing, live-system access or proof of event completeness. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Convert a measurement without losing declared uncertainty: one decimal value and standard uncertainty across supported length, mass, time or temperature units using exact rational scale/offset arithmetic. No unit guessing, physical validation or expanded uncertainty. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Review permission changes before an agent release. Compare two explicit allow-only sets by tool, action and exact resource; report additions, removals and wildcard additions. Does not resolve IAM inheritance or wildcard containment, or authorize execution. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Check declared publication views before release. Compare 2-8 article, registry and API views against canonical URL, content, release and source-set digests; flag stale, withdrawn or substituted views. No live fetch, release promotion or semantic content verification. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Interpolate between two integer-coordinate points with exact rational arithmetic and an integrity receipt. Refuses extrapolation and repeated nodes. Does not estimate measurement error or validate the interpolation model. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Prepare a reproducible research handoff from supplied public or synthetic artifact contents, dependencies, algorithm version, seed and Supplied-record analysis, not independent certification. Full contract at the free describe URL.

Classify up to 100 declared measurement intervals against tolerances as pass, fail or hold. Integer millimetres; uncertainty is an absolute interval half-width, not a confidence level. No sensor verification or engineering approval. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Inspect a declared dependency graph of up to 64 nodes and 128 edges: exact cycle membership, source-root reachability, and deterministic graph digest. Duplicate edges and dangling references are rejected. Hash declarations are not authenticated. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Convert half-open UTF-8 byte, UTF-16 code-unit, or Unicode code-point spans into all three units for supplied text. Reject offsets inside a code point. No PDF parsing, page inference, or external source lookup. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.
