Everything we
build to use.

Eligibility-as-code: a domain-agnostic engine that turns messy qualification rules into explainable, auditable verdicts with evidence.

Framework-agnostic, type-safe filtering for TypeScript: one filter definition that runs in memory on the client and translates to Prisma, MongoDB, or SQL on the server.

Deduplicate concurrent async calls: same key, one in-flight promise. Not a cache.

Tiny integer-cents money type , safe arithmetic, currency-aware rounding, Intl formatting. No bignum, no dependencies.

Truncate strings by byte budget without ever breaking a grapheme , safe for DB columns, headers, and anything with a byte limit.

Poll an async producer until a predicate passes , exponential backoff with jitter, overall timeout, AbortSignal, returns the value

Parse Server-Sent Events from a streamed LLM response , cross-chunk safe, spec-correct, transport-agnostic, zero deps.

Trim a chat message array to fit a token/size budget , keep the system prompt, pin the most recent turns, never split a message.

Debias a biased bitstream (e.g. from a hardware/quantum RNG) with the Von Neumann extractor and an optional XOR-fold whitener. Classical, zero deps. NOT a cryptographic RNG.

Extract the first (or every) valid JSON value embedded in text or markdown fences from an LLM reply. Locates and parses; does not repair.

Best-effort parse of an incomplete/streaming JSON prefix , closes open strings, arrays, and objects so you get a usable value at every step. Never throws on truncation.

Self-cleaning temp files and directories , scope-bound via `using`, swept on crash and signal, zero dependencies.
