Pillar 02 · Convert

Universal Translator — old stack in, modern stack out.

Convert peels any origin into one middle (WebIR + CWL), then emits a modern target. AI can draft the work; recorded traffic decides what ships. If something cannot be claimed safely, it stays a labeled hole — never a fake finish.

  1. 01 Origins in PHP, Java, Node, …
  2. 02 One middle WebIR + readable CWL
  3. 03 Modern out after traffic matches
Chrysalis Universal Translator: PHP, COBOL, SvelteKit, Express, and Java translate only into WebIR plus CWL, then emit TypeScript, Java, Python, Go, and Hono. LLM proposes; verify disposes. Honest hole when origin is missing. No invented runtimes, no demo façades, open path to fidelity.

How Convert works

Translate only. Prove what you claim.

01

Origins in

PHP, COBOL, SvelteKit, Express, Java, and more enter the same spine — not a one-off converter for every pairing.

02

WebIR + CWL

Portable IR plus the readable genome. People can audit the lift; machines can emit from one model.

03

Modern out

TypeScript, Java, Python, Go, Hono, and other targets — only after replay matches recorded traffic.

No invented runtimes. No demo façades. Open path to fidelity.

Owns / does not

Convert owns peelers, emitters, Hub SPA, oracle harnesses, Pilot Kit, Chimera shell. It does not own CWL RFCs/golds or the UT DNA spine (smoke:ut-spine lives in chrysalis-cwl).

  • Flagships: laravel-min, tiny-blog
  • Pilot Kit: pilot:laravel-min, pilot:cobol-clbs (COBOL inventory / GTM wedge — lives in Convert, not a separate PyPI package)
  • Gate: hub:traffic-decides-bar-smoke → TRAFFIC_DECIDES_CONVERT_OK
  • Residuals stay labeled (Nest / LiveView / Flutter façades catalogued; COBOL EXTFMAP-class holes stay honest)
