ETERN Toolkit

AI-assisted recovery tools for aging software.

ETERN Toolkit helps engineers analyze, revive, and modernize aging software systems with minimal disruption.

It is designed for legacy recovery workflows such as:

• deprecated API detection
• framework migration assistance
• dependency repair
• Docker environment generation
• database compatibility analysis
• configuration reconstruction

The goal is simple:

Make old software runnable again.

Philosophy

Recover first. Replace only when necessary.

Legacy systems often contain:

• valuable business logic
• undocumented behavior
• irreplaceable operational knowledge

Blind rewrites destroy these.

This toolkit exists to preserve them.

Planned Features

scan

Analyze legacy source code.

Example:

lrt scan ./legacy-project

Detect:

• deprecated PHP functions
• removed framework APIs
• obsolete dependencies
• incompatible runtime assumptions

---

doctor

Generate recovery suggestions.

lrt doctor

Examples:

• replace mysql_connect() with PDO
• identify missing extensions
• detect framework upgrade blockers

---

dockerize

Generate isolated runtime environments.

lrt dockerize

Output:

• Dockerfile
• docker-compose.yml
• runtime compatibility notes

---

migrate

Generate minimal modernization patches.

lrt migrate

Goal:

• preserve behavior
• minimize code changes
• keep patches reversible

---

Target Users

• legacy software consultants
• PHP maintenance engineers
• small technical teams
• digital preservation specialists
• organizations with undocumented systems

---

Status

Early design phase.

This repository currently defines:

• ideas
• architecture
• specifications

Implementation will begin incrementally.
