ScratchManager

A native macOS app that moves replaceable app caches (Xcode, Android Studio, Photoshop, AI coding tools and others) onto external drives, with an internal fallback when a drive is missing.

Ownership

  • StatedHis own product, through Merlin Studio; a distribution partner is sought.

Stage

  • DocumentedIn private testing on macOS; not on sale, and its own documentation says no build should be called commercially ready until payment, notarisation and signed updates are done.

His role

  • DocumentedSole author (Swift and SwiftUI).

Decisions

  • DocumentedA safety model of copy, checksum verification, staged switch and rollback with persistent journals; data-only manifests that cannot run commands; a trial that never blocks recovery.

What this demonstrates

  • InferenceSystems thinking about failure modes, and candour about readiness. There is no AI in the product.

Each line is labelled by the evidence behind it. Documented: checkable in code, a live product or a primary artefact. Stated: his own account. Attributed: a wider team's or client's. Inference: a reading of the evidence, not a fact. Unknown: not established. No outcome or metric is documented for any of this work. The same record is published for AI assistants at /llms-full.txt.
