SlimeRESCUE-VOS3 RELEASED

Direct bit-exact conversion from z/Architecture load modules to Java/COBOL/Rust/C#/Kotlin/Go.

Hitachi VOS3 / Fujitsu MSP / Fujitsu GS21 / IBM z/OS all use the same z/Architecture ISA, forming a PCM (Plug Compatible Mainframe) family. A single codebase covers them all. 2026-05-20: 6 phases completed in one session = MVP achieved, and cross-validated against the Hercules 3.13 official emulator — for the scope of that verification see the primary materials.

🎛 AI GATE This page, at your resolution.

Hand rewrites drift on subtle numeric/exception differences (boundary conditions), and verifying that (old-vs-new testing) costs enormous labour. SlimeNENC faithfully mirrors language-specific traps, proves "zero divergence" via differential testing, backed by an independent reference implementation. The deliverable is a machine-checkable "certificate of behavioural invariance," not human UAT. No overstating; what it can't do isn't hidden.

Implementation and verification — primary materials — the implementation phases and their size, the Hercules 3.13 cross-validation and its correction, the instruction inventory, the WASM build, and the current scope of verification are collected in SlimeRESCUE-VOS3 — primary materials.

Operational example (real curl)

POSTing an s390x ELF to the Phase F-1 HTTP service (port 8770):

# 8 z/Arch instructions (AR/A/LM/STM/MVC/AP/CLI/BCR) wrapped as s390x ELF
$ curl -s http://127.0.0.1:8770/health
ok

$ curl -s -X POST --data-binary @sample.elf \
    http://127.0.0.1:8770/slimerescue/slot
# format: elf
# dialect: s390x-linux
# instructions: 8
# slots: 8
SLOT  op=STMT_COMPUTE    ck=STMT  tt=BIN     ext=0x000000c8 ; "ar R1=1 R2=2"
SLOT  op=STMT_COMPUTE    ck=STMT  tt=BIN     ; "a R1=1 X2=3 B2=4 D2=4032"
SLOT  op=STMT_MOVE       ck=STMT  tt=BIN     ; "lm R1=2 R3=5 B2=6 D2=3840"
... (8 slots total)

$ curl -s -X POST --data-binary @sample.elf \
    "http://127.0.0.1:8770/slimerescue/java?class=DemoCobol"
public final class DemoCobol {
    public static void main(String[] args) {
        long[] R = new long[16];
        byte[] M = new byte[1<<20];
        /* ar R1=1 R2=2 — COMPUTE */
        R[1] = (R[1] + R[2]) & 0xFFFFFFFFL;
        ...

Technical specifications (detailed)

Supported ISA	IBM S/370 / 390 / z-Architecture (all 1,778 distinct opcode keys in the table reach a decoder = 100.0%, format families 33 / 33 incl. vector; the figures are generated in the primary materials)
Binary formats	s390x ELF64 BE (Linux) + z/OS LOADLIB (PDS, 256-byte directory blocks, EBCDIC names)
dialect_id	DIALECT_S390_LINUX = 200, DIALECT_S390_LM = 201 (no collision with existing SlimeNENC dialect space)
Slot IR	Compatible with existing SlimeNENC Core64 + Ext32, `slot.c slot_print()` output match (existing backend reusable)
Target languages	Java / COBOL / Rust / C# / Kotlin / Go (existing SlimeNENC S6 emitter, 5 languages)
EBCDIC support	Python `cp037` codec, PDS member name recovery, COBOL string handling
Packed BCD	COMP-3 compatible, AP/SP/CP decimal arithmetic (1-16 byte length)
Policy compliance	HTTP service 127.0.0.1 enforced (no public exposure), follows existing SlimeNENC service policy

Applicable scenarios

Hitachi VOS3 retirement engagements: regional banks / municipalities / utilities blocked by source loss
Fujitsu MSP / GS21 retirement engagements: legacy Amdahl / Fujitsu PCM users, MSP-adjacent code shares VOS3 path
IBM z/OS LOADLIB legacies: load modules compiled 30-40 years ago and left untouched, source unmanaged
Post-M&A asset reorganisation: source location unknown after merger, only PDS / LOADLIB remains
Audit requirements: surface the logic encoded in load modules (Slot IR + Java equivalent) for documentation

Related / pricing

SlimeRESCUE-VOS3 is a binary-first premium SKU. 5-10x the unit price of source-based SlimeCOBOL (no alternative + market monopoly). PSDP bundling, volume discount, and SIer partner margin via Partners. Details disclosed under NDA.
