Package driver runs a project's tracker driver: an executable at .f10/driver satisfying the verb contract in docs/driver-contract.md.

Package facts interprets the declared project.md layers, merges them with the detection probes and the contract's defaults, and attributes every effective value to its origin.

Package gitx is the binary's one door to git.

Package herdr is the binary's door to Herdr, the terminal multiplexer `f10 start` opens a task's worktree in, `f10 forward` reaches its agent through and `f10 finish` closes it from.

Package layout locates the f10 configuration layers for a working directory: the checkout root, the instruction layers in precedence order, their layering mode, and the storage root.

Package probe runs the deterministic detection probes bin/bundle.sh runs: remote host and CLI routing, stack and verify marker files, and the existing plans.

Package projects maps a bare project name to a checkout directory, for `-C r3` run from somewhere else entirely.

Package ref looks up which task a lookaround command is about.

Package shell is the binary's door to every external command that is not git: a tracker CLI, a project's driver, a pager, an editor, the OS opener.

Package state reads the run state bin/f10-state.sh writes: one small `key value` file per session under ~/.claude/f10/state, keyed by session rather than by repo because two sessions over one checkout are two runs.
