Installation commands and release details remain intentionally gated until the Coldstart product snapshot is confirmed.
What it is
Coldstart is the next public name for Achron Spine: a local operating-discipline layer that helps an AI coding agent begin with the right context, stay inside an agreed scope, and prove what it changed before calling the work done.
Context that survives
Project plans and progress pointers make a fresh session cheap to resume.
Guidance on demand
Small router skills load only the discipline or reference the current task needs.
Verification built in
Work closes against explicit checks instead of a confident-looking summary.
Why it exists
Strong models can still drift, guess, or lose the thread in a long build. Coldstart puts a lightweight operating system around that work: what matters now, what is out of scope, where decisions live, and which evidence counts as done.
Give every session a reliable beginning—and every handoff enough truth to continue.
How it works
The workflow is intentionally small. Each stage leaves behind something the next session can trust.
Quickstart
The final release will expose one verified install path here, with platform-specific notes directly below it.
$ git clone <release-url> ~/.coldstart && ./install.shDo not use this command yet. It demonstrates the copyable command pattern only.
Migration from Spine
Existing Spine users will get a first-class migration path, not a rename footnote. It will explain what changes, what remains compatible, how customer access is preserved, and which old links continue to work.
