v2.0.0 — Machine enforcement + non-VCS mutex

This release makes the kit work without git and adds the first machine-checkable enforcement layer.

What's new:

• Non-VCS mutex: filesystem lock files replace git branches — the kit now works on any project regardless of version control
• docs/AGENT_BRIEF.md: 30-second entry point every agent reads first
• docs/TEAM_ONBOARDING.md: roles, onboarding, conflict escalation for teams of 2+
• Framework quick-starts: Laravel, Next.js, FastAPI, monorepo
• check-scope-overlap.sh + validate-checkpoint.sh: automated CI gates that fail on scope conflicts or incomplete checkpoints
• SETUP_PROMPT: git no longer a blocker; prompt-injection scan added

Everything is still MIT-licensed, zero dependencies, and works with any agent tool.

v1.5.1 — README alignment

README now reflects v1.5.0's capabilities:

• FAQ: web-chat agents without file access can also initialize the system (the setup prompt embeds the full file-structure spec)
• Quick Start: notes the dedicated-subfolder behavior when a project already has its own docs/

v1.5.0 — Universality audit

Word-by-word audit of the full kit, focused on making it work for any project, any task, any repo, any app.

Added

• SETUP_PROMPT Step 4: from-scratch file-structure spec — agents without access to the kit folder (e.g. web chat) now rebuild faithful governance structure instead of inventing their own
• docs-folder collision rule: governance files never mix into an existing product docs/
• Non-technical owners can answer "I don't know" to verification questions and get proposed defaults

Changed

• START_HERE model-selection block fully self-contained (no dangling reference to the kit's patterns folder, which isn't copied into projects)
• PENDING-OWNER check added to the session-start loop
• Amendment channel covers solo projects (owner directly)
• Setup-prompt archive step + appendix wording fixes

Fixed

• Checkpoint template typo, missing Class-12 separator, cost-zero table as-of date
• Failure Class 3 genericized (marketplace terms removed)
• Emoji status glyphs in worked example replaced with [OK]/[WARN]/[DEAD]

v1.4.1 — README polish

README optimized against niche research (github/spec-kit, BMAD-METHOD, awesome-claude-code):

• New banner (media/banner.svg) — visual identity with the three-mutex motif
• Linked badge row: release, version, stars, license, discussions
• GitHub callouts ([!TIP], [!NOTE], [!WARNING]) replacing plain blockquotes
• Mermaid diagram of the thread loop (renders natively on GitHub)
• Tighter founder story + new Community section

No changes to the kit itself — docs/, patterns, and SETUP_PROMPT are untouched.

v1.4.0 — Easier to use, built from real mistakes

System Kit v1.4.0

Headline change

templates/ is now docs/. The governance files are now the actual docs folder the agent copies into your project and fills in — no more "templates" concept to understand. You get docs; your AI agent fills them.

For non-technical users

• New "Why I Built This" section — the founder's real incidents (hallucinated APIs, agents destroying each other's work, key leaks, untested code in production, context-loss, mislabeled data) that became every pattern in this kit
• Terminal-free Quick Start — Download ZIP → paste the setup prompt → answer plain-English questions → done. You never edit a file by hand.
• New FAQ: "Do I need to be technical to use this?" — No.

Verified

Full end-to-end smoke test passed before release: empty project → copy docs/ → fill placeholders → complete thread lifecycle (claim → register → work → close out) → conflict detection between two threads → checkpoint flow. The CI governance check (links, placeholders, version, registry) passes on all tracked files.

Breaking note

If you linked to templates/ paths, they are now docs/ paths. File contents unchanged (100% rename, git history preserved).

v1.3.4 — Ready to use

System Kit v1.3.4

Portable governance infrastructure for AI-agent development teams. Copy one folder into any project, paste one prompt into any agent, and get instant multi-thread coordination, task tracking, verification gates, and institutional memory.

What's inside

• SETUP_PROMPT.md — single-prompt initialization with troubleshooting appendix and edge-case handling (empty projects, monorepos, polyglot, no test framework, no git)
• 9 patterns — concurrency (three-mutex model), verification, security checklist, 12 failure classes, cost-zero operation, model rotation, prompt injection defense, context window management, worktree parallel coding
• Templates — START_HERE entry point, AGENTS laws framework, THREADS registry, task board, build log, checkpoints
• Worked examples — fully initialized START_HERE and a live THREADS registry
• Optional CI gate — GitHub Actions workflow validating links, placeholders, version consistency, and registry presence

Highlights since v1.0.0

• Model selection made optional (domain-neutrality fix)
• CI link-checker rewritten and verified correct
• Empty-folder greenfield path live-tested
• Issue templates for pattern proposals and bug reports

Zero dependencies. Zero telemetry. MIT licensed.
