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 frontmatter splits a markdown file's leading YAML block from its body.

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 mdline reads the `key: value` lines f10 takes out of markdown that people and agents edit: project.md's facts and a task body's After: line.

Package model reads a claude model name as a person or an agent typed it: a family, a family and a version, or a full id.

Package probe runs the deterministic detection probes bin/f10-load-project.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 standup groups one person's activity in a checkout by task: the commits they authored and the PRs or MRs they opened, reviewed or merged, collected by `f10 standup` from git and the host CLI.

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.
