Transmute — project migration

Transmute migrates an entire software project from one language/ecosystem to another using a semantic pipeline — not file-by-file text translation.

CLI

# Analyze + migrate a project
plx migrate ./examples/weather-api --to rust --output ./examples/weather-api-rust --verify

# Plan only
plx migrate ./api --to rust --dry-run

# Quality gates
plx migrate ./api --to rust --require-build --require-tests --min-confidence 0.9

# Origin lookup (source maps)
plx origin src/service.rs:14 -C ./examples/weather-api-rust

plx migrate auto-selects Transmute when the path is a project directory (or --to is a language such as rust). Use --mode value for PIR state migration of a single guest program.

Representations

IRMeaning
PIRValues / heap bindings
PUIRProgram semantics (functions, types, intent ops)
PCIR / UESSuspended execution (Continuum)
ProjectGraphModules, deps, edges, entrypoints, tests

PUIR is versioned independently (puir_schema on plx version).

Workspace

Migrations write .parallax/ under the source root (project.json, graph.json, puir.json, plan.json, …) for inspection and future incremental updates.

Demo

plx migrate examples/weather-api --to rust -o examples/weather-api-rust --require-build --require-tests
cd examples/weather-api-rust
cargo test
cargo run

See PARALLAX_MIGRATION.md and parallax-report.json in the output directory.

Honesty rules

  • Compatibility percentages come from measured analysis (PUIR coverage, dep confidence, …) — never invented.
  • Uncertain regions get // PARALLAX REVIEW: markers and report entries.
  • Secrets in .env are never copied; only .env.example names are emitted.
  • Cross-language project migration is not Continuum live-stack resume.
