Behind jackin' — InternalsRuntime Model

Runtime Model

How jackin' models container instances, names resources, stores configuration, and manages schema versions.

  • Runtime Instance Model — vocabulary, invariants, lifecycle statuses, and the launch and hardline decision models.
  • Instance & Resource Naming — how container names, Docker resources, image names, state directories, and cache paths are derived.
  • Configuration File — config.toml schema, storage locations, and persisted state.
  • Schema Versions — config/workspace/manifest versioning, migration timeline, and the version format.
  • Run Diagnostics — per-run JSONL event schema, container lifecycle tracking, stage timings, and how to use the run ID for crash triage.
