Data Science and Engineering Foundation

Goal

Keep Data Science and Engineering Coach orchestration consistent across job changes and sessions without duplicating job-specific guidance. The coach loads this index at initialization and resume, then reads the reference for the current coaching moment.

Reference index

Reference	When to read
job-registry.md	Before offering or selecting a job, routing to a skill or specialist, or naming a durable output
lifecycle-classes.md	When starting, pausing, resuming, completing, or re-invoking a job
transition-protocol.md	When a topic shift, explicit request, or completion suggests moving between jobs
session-state.md	Before initialization, validation, mutation, resume, recovery, or reconstruction of coaching state
flow-state.md	Before interrupting work, crossing a gate, writing a durable artifact, or offering post-job choices

Success criteria

• Each orchestration rule has one owner in this package.
• State and lifecycle mechanics remain independent of job-specific methods.
• The coach reads the applicable reference before acting on its contract.
