COBREV reconstructs decades of enterprise business intelligence embedded inside legacy systems and transforms it into traceable, verified, modern architectures. Built on the KAIROS multi-model orchestration platform.
Every major bank, insurer and federal agency still runs on COBOL systems written decades ago — encoding business rules that no one alive fully understands. Modernization isn't a tooling problem; it's a knowledge reconstruction problem.
Still in active production across Fortune 500 enterprises and federal agencies.
Of the mainframe engineering workforce. The institutional memory leaves with them.
Of business rules embedded in COBOL exist nowhere except the source code itself.
Average modernization cost for a single core banking subsystem — most projects fail.
For a manual rewrite. Most enterprises restart 2-3 times before delivering.
Not a transpiler. A complete cognition pipeline that recovers what the code means, validates the meaning against runtime behavior, and emits a modern architecture you can trust.
Recovers types, business rules, decision trees, 88-level conditions and implicit edge cases. The source code is parsed, the meaning is reconstructed.
Six specialized AI passes orchestrated with deterministic contracts. Reasoning models, semantic analyzers, and validators with contradiction detection.
Runtime equivalence validation. Formal proofs. Sandboxed property fuzz. Auto-correction loops. Every output ships with a signed audit bundle.
KAIROS coordinates reasoning engines, semantic analyzers and deterministic validators across each pass — with contradiction detection, correction loops, and confidence scoring built into the substrate.
“This is not code conversion.
This is enterprise system cognition.”
Continuous semantic indexing of the live mainframe. Every program, every dependency, every dataset binding — queryable in natural language.
Every formula, decision tree, 88-level condition and implicit rule extracted with provenance. Searchable, exportable, owned by the business.
Every line of generated target code traces back to a source paragraph, an extracted rule, a verified contract. Regulators don't have to ask.
COPYBOOK transitive closure. JCL dataset bindings. DB2 schema dependencies. CICS transaction graphs — modeled as a single queryable graph.
Approval gates per module. Threshold-bound auto-ship. Human review with full context. Audit trails retained WORM for the life of the system.
Shadow execution against live mainframe traces. Property fuzz tests synthesized from PIC clauses. Discrepancies fail the build — not the cutover.
Every output produces a signed, immutable proof bundle. Every decision is auditable. Every human-in-the-loop checkpoint is logged. Modernization without governance is just risk transfer.
Independent 10-category fidelity scoring across structural coverage, business logic, control flow, runtime stability, and production readiness.
Formal theorem proving over the full PIC envelope. For every input that the source accepts, the target produces an equivalent output — or the proof returns a counter-example.
Every target line cites a source paragraph. Every business rule cites a decision tree. Every approval cites a reviewer and a timestamp. Nothing is undocumented.
Signed, immutable logs retained for the life of the system. RSA-4096, HSM-resident keys. No COBREV access required to verify.
Formal · Structural (AST diff against KIR) · Behavioral (8,192-case property fuzz). Three independent checks before a single PR is merged.
Below-threshold outputs surface to a reviewer with full context, full proof, full diff. No silent overrides. No black-box decisions.
Schedule a one-hour technical review with the COBREV engineering team. We'll walk through your modernization estate, deploy a sandboxed pilot against your hardest 50 kLOC, and deliver a verified target with a complete proof bundle in 14 days.
