0.1.6 - 2026-05-31

post-tool-use-bash hook is now stub-once (#22). It previously appended a ## Commits so far line on every command matching the glob *git*commit* (echoes, git log | grep commit, doc strings), with no new-commit check and no dedup, and rewrote a tracked file after each commit without staging it. The working tree never settled (committing the draft re-fired the hook), and the churning .ytstack draft was invisible to a worktree branched from main, breaking spawn-milestone-team dispatch. The hook now matches a real git commit (after a command separator), creates the draft stub once, and never re-writes it.

Commit-to-task linking moved into summarize-task (#22). It greps git log for the M###-S##-T##: commit ref into a committed ## Commits section, replacing the throwaway hook draft. See DECISIONS 2026-05-31 "post-tool-use-bash is stub-once".

Swarm Fix-Pack (M012), resolving four issues found running milestones as parallel Agent-Team swarms:
- verification-before-completion crashed for every user: a literal triple-backtick inside an executable block truncated the extracted preamble (#20). Fences are now generated at runtime and matched by prefix.
- pre-tool-use-edit now exits 0 (advisory) instead of hard-blocking, and short-circuits on .ytstack/** paths (#19).
- active_slice / active_task writes are guarded for swarm teammates and treated as a single source of truth (#21).
- hooks read session_id from stdin JSON instead of a non-existent env var (#21).
- reassess-roadmap gained a backlog sweep (#16).

Initial release: the full ytstack build cycle (M001-M009). Skills for the Project-OS lifecycle (init-project, plan-milestone, slice-milestone, plan-task, summarize-task, reassess-roadmap, handoff-session, resume-session), curated gstack planning wrappers and superpowers execution wrappers, spawn-milestone-team for Agent Teams, the using-ytstack SessionStart directive, eight hooks, three subagent definitions, and the .ytstack/ artifact model (PROJECT / DECISIONS / KNOWLEDGE / STATE / milestone-slice-task hierarchy).
