SlimeNENC — Legacy Modernization Transpiler Family

Deterministic, audit-grade, bit-exact modernization from legacy to modern languages.

SlimeNENC is an umbrella brand for four products. They modernize 30+ year-old legacy assets in finance, pension, healthcare, and public-sector systems with bit-exact correctness and audit chains.

Four-product portfolio

All four share the same Slot IR + language-independent S2-S5 / S7-S9 pipeline; only S1 (front-end) and S6 (emitter) change to extend coverage.

Conversion (Subset A)

SlimeCOBOL

14 dialects NIST 501 99.9995% 5 emitters

COBOL → Java / Rust / C# / Kotlin / Go bit-exact transpiler. Auto-detects 14 dialects (IBM / Burroughs / Unisys / Hitachi OpenTP1 etc.), validated on NIST CCVS85 501 programs. Production-grade migration line for regional banks, insurance, pension.

Conversion + Control

SlimeJCL 2026-Q3

4 major dialects Spring Batch SlimeNENC pair

JCL → Spring Batch transpiler. Fingerprints IBM z/OS / Fujitsu / Hitachi / NEC. Bit-exact translation of the JCL that always accompanies COBOL batches. Ships exclusively to SlimeNENC customers; one-tool migration project completion.

Conversion (Healthcare)

SlimeMUMPS

9 dialects S9 73/73 Java + Clojure HIPAA

MUMPS → Java / Clojure bit-exact transpiler. Detects 9 dialects (GT.M / Caché / IRIS / YottaDB / FreeM / MiniM / MV1 / ANSI-95). Core engine for healthcare-EHR migration (VistA / Epic / Meditech), with SlimeTree-RLM B-Tree persistence + audit chains built in.

Conversion (Insurance / Banking / Aviation)

SlimePL/I

5 dialects S9 60/60 byte-exact 60/60 Full file I/O

PL/I → Java bit-exact transpiler. Detects 5 dialects (IBM Classic / Enterprise / Open PL/I / Iron Spring / GnuPLi). For insurance, banking, and aviation (SABRE / Amadeus-class) PL/I assets → Java. Array-of-struct + internal PROC + RETURNS + recursion + stdin/file I/O all live.

Conversion (IBM iSeries / AS400)

SlimeRPG

RPG IV free S9 35/35 byte-exact 35/35 Full file I/O

RPG → Java bit-exact transpiler. Native target: IBM Power Systems / iSeries / AS/400 with RPG IV free-format. For banking, manufacturing, distribution, insurance RPG assets → Java. Arrays + DCL-DS + internal PROC + recursion + 17 BIFs + file I/O (DCL-F / READ / WRITE / %EOF).

Conversion (HPC / Numerical)

SlimeFORTRAN

F77 fixed → F2018 free S9 25/25 byte-exact 25/25 gfortran compile 25/25

FORTRAN 77 (fixed-form col 1-72) → modern FORTRAN (F2018 free-form) bit-exact transpiler. Targets F77 numerical assets at NASA / ECMWF / Japan Meteorological Agency / JAEA / university labs. Auto IMPLICIT NONE injection + DO/CONTINUE structuring + SUBROUTINE/typed FUNCTION/COMMON/SAVE/EXTERNAL/function-as-arg/arith IF/computed GOTO/OPEN/REWIND/READ/CLOSE complete.

Parallelization (Subset B)

PSDP

Phase-sync bit-exact 11 safety mechs

Phase-Synchronized Deterministic Parallelism. Converts a sequential batch into a parallel batch in the same language — output unchanged. Java×Java / Rust×Rust + cross-version moves included. Independent SKU; not bundled with the converters.

Common safety mechanisms (across all products)

Bit-exact	Output matches input behavior down to the bit; same input → same sha256.
Round-trip	Convert + reverse-convert produces token-identical source. Formal proof of zero information loss.
Audit chain	SHA-256 monotonic chain over every conversion step. Detects single-byte tamper.
Rollback	Tombstone-based; chain is append-only, full prior state recoverable.
Determinism	Stable across parallel and GPU execution (Hilbert ordering + indexed lookups).
Hallucination	Trigram + bigram detect 95% of mistranslations; silent-pass under 1.1%.
Build-time LLM	LLM is used only at rule-construction time; runtime is deterministic rules — basis of the 99.9995% claim.

Land-and-expand path

Phase 1: Migration tool — SlimeCOBOL / SlimeMUMPS prove "bit-exact convertible" with audit chain
Phase 2: Same engine for batch JCL — Add SlimeJCL, single-tool project completion
Phase 3: Parallelize on the modern target — PSDP makes existing Java/Rust batches parallel, output unchanged

Each product is an independent SKU; no bundling.
