Package bundle turns a problem into a candidate drop: the candidate-visible files rendered for one variant, plus the front page that orients whoever opens it.

Package cli dispatches interviews subcommands.

Package content defines the problem manifest and loads one problem directory into a validated Problem.

Package debug runs live debugging scenarios: it deploys a healthy environment from a problem's env spec, injects the variant's fault pack, checks and fixes faults, and proves in CI that every fault still breaks and every documented fix still works.

Package fileio writes the small files a session workdir accumulates.

Package grading holds the resourcefulness-first rubric and renders grading sheets.

Package interview keeps the per-machine record of interview sessions: what exists, what it was, and which one the commands mean by default.

Package leak decides what a candidate may ever see.

Package provenance records what an artifact was produced on.

Package redteam drives a frontier coding agent at a problem the way an unassisted candidate would meet it, then records what it managed and how fast.

Package registry discovers every problem in a content root and holds the cross-problem invariants: the root contains only the known type directories, and problem ids are unique across all types.

Package session runs the live layer over a debugging environment: a shared tmux session recorded from the start, exposed writable to the candidate and read-only to the observer through ttyd, with evidence bundling and a fault timeline for grading afterwards.

Package sysdesign validates system design problems.

Package taxonomy fixes the vocabulary of the content tree: interview types, debugging flavors, take-home classes, disciplines, and level bands.

Package variant resolves a problem's parameters for one interview, deterministically.

Package version holds the release version, stamped by release-please.
