+# Changelog
+
+All notable changes to `cli-maxxing` are documented here.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+### Added
+- README: social-links badge strip (X · LinkedIn · YouTube · Instagram, ruvnet-style for-the-badge) inserted into the centered header block beneath the banner.
+- **`cbrain` + `cbraintg` shell shortcuts** (step 10.9) — quick-launch aliases for the Brain² + Telegram-bridged sessions.
+- Step 5 — full upstream URL verification across all five external MCPs (morgen / motion / playwright / granola / n8n).
+- Step 7 — GitHub MCP migrated to the hosted endpoint at `github/github-mcp-server` (the deprecated `@modelcontextprotocol/server-github` is removed).
+- Step 5 — Notion MCP migrated to the hosted OAuth endpoint at `https://mcp.notion.com/mcp`. No integration token, no per-page sharing — Notion handles auth on first use via browser OAuth.
+- Step 5 — Google Calendar MCP swapped to `@cocal/google-calendar-mcp` (actively maintained); the bare `google-calendar-mcp` package was a year-stale fork.
+
+### Changed
+- Git history rewrite: `git filter-repo` collapsed all author/committer identities (dependabot[bot], lorecraft-io, nate variants) into a single `Nate Davidovich <nate@lorecraft.io>` identity across `main` and both release tags (v1.9.1, v2.0.0). All `Co-authored-by:` trailers stripped (162 of them — mostly `claude-flow <ruv@ruv.net>` carryover from pre-rebrand). Tag commit hashes changed; this repo has no published npm artifact, so no downstream impact.
+- Step 6 ordering — `gh` CLI moved from Step 3 to Step 7 so the full GitHub stack (CLI + MCP + workflows) ships together.
+- Step 5 — design-stack MCPs (Figma / Excalidraw / Gamma / Magic / YouTube / IG) removed from cli-maxxing cheatsheets — these now live exclusively in the `creativity-maxxing` install. cli-maxxing remains the lean core terminal install.
+- Step 5 — `2ndbrain-maxxing` references flipped to `2ndBrain-mogging` across `README-SECTIONS/` and `tests/`.
+
+### Fixed
+- Step 1-5 — anchored MCP grep patterns at `^<name>:` so substring matches don't trigger false-positive "already installed" detection.
+- Step 5 — BSD grep compat fix in Motion detection (macOS `grep` doesn't support `-P` like GNU does; pattern simplified accordingly).
+- Step 6 — `SAVED_TOKEN` env var unset after self-test validation so a stale value doesn't leak into the next step.
+- Step 7 / Step 8 / step-final — atomic MCP match patterns tightened to prevent partial overlaps.
+- `uninstall.sh` + `INSTALL.md` — `cbraintg` ownership note + stale references cleaned up.
+- Sub-modules: `gitfix-skill` and `rmini-skill` picked up the residual stash improvements from the step-forward rebase.
+
+## [2.0.0] - 2026-04-15
+
+### Changed — Major split + rebrand
+
+This is the first version after the post-mogging split (per `project_cli_maxxing_split`). The original "AI Super Setup" stack was carved into three focused repos:
+
+- **cli-maxxing** (this repo) — core terminal install: shell, package managers, Claude Code, MCPs (calendar/task/automation), GitHub stack, safetycheck.
+- **creativity-maxxing** — design / video / audio / transcription tooling.
+- **2ndBrain-mogging** — Obsidian + Claude Code second brain + skills + scheduled agents.
+
+### Added — Step structure
+- 8 numbered steps + 1 final step, with one command per step. See `README-SECTIONS/step-ordering.md`.
+- `gitfix-skill` and `rmini-skill` as in-tree submodules.
+- `terminal-academy` submodule — gamified terminal trainer.
+- `templates/` — reusable install-step scaffolds.
+
+## [1.9.1] - pre-rebrand
+
+Last release under the "AI Super Setup" branding. Preserved as a tag for lineage.
