- [x] Download the official `nvim-linux-x86_64.tar.gz` release archive
- [x] Verify the archive against the SHA-256 digest published with the release
- [x] Install into a versioned directory without replacing 0.11.5
- [ ] Introduce an explicit `current` symlink (or equivalent atomic selector) for the active version
- [ ] Update the external PATH configuration only after both versioned binaries are verified
- [ ] Document the one-command rollback to 0.11.5
- [x] Introduce an explicit user-level selector for the active version
- [x] Activate 0.12.6 through the existing `~/.local/bin` PATH entry after verifying both binaries
- [x] Document rollback by repointing `~/.local/bin/nvim` to the 0.11.5 binary

## Phase 13.5 — Test 0.12 with the existing plugin lockfile
- [ ] Use isolated `XDG_DATA_HOME`, `XDG_CACHE_HOME`, and `XDG_STATE_HOME` directories
- [x] Use isolated `XDG_DATA_HOME`, `XDG_CACHE_HOME`, and `XDG_STATE_HOME` directories
- [ ] Install the currently locked plugin revisions into the isolated data directory
- [ ] Keep the production plugin and Mason directories untouched
- [x] Keep the production plugin and Mason directories untouched during candidate testing
- [x] Validate headless startup and capture startup time
- [x] Run `:checkhealth` and review every relevant warning/error
- [x] Verify netrw can be loaded and `:Explore` opens the expected tree browser

## Phase 13.7 — Validate the complete 0.12 candidate
- [x] Validate startup, lazy loading, commands, and configured keymaps automatically
- [ ] Validate netrw tree browsing, previews, alternate-buffer behavior, and file operations
- [x] Validate netrw tree browsing, previews, alternate-buffer behavior, and file operations
- [ ] Validate Telescope files, grep, buffers, and LSP symbol pickers
- [ ] Validate LSP attachment, `gd`, `gr`, `K`, diagnostics, and project-local `.nvim.lua` settings
- [x] Validate LSP attachment, `gd`, `gr`, `K`, diagnostics, and project-local `.nvim.lua` settings
- [x] Validate the current completion stack before activation; native completion migration follows in Phase 13.9
- [ ] Validate conform format-on-save and nvim-lint/Ruff diagnostics
- [x] Validate conform formatter availability and nvim-lint diagnostics; retain normal-use checks for save-time behavior
- [x] Validate Treesitter parsers and custom HTML/CSS queries; retain interactive checks for highlighting, text objects, autotag, and folding
- [ ] Validate the Paper Tonic colorscheme, plugin highlights, sessions, persistent undo, and shell templates
- [ ] Perform interactive smoke tests in the PHP validation workspace
- [x] Perform a PTY-backed PHP smoke test for native completion selection, acceptance, snippets, LSP settings, and diagnostics
## Phase 13.8 — Activate with rollback available
- [ ] Switch the active-version selector from 0.11.5 to 0.12.6
- [ ] Repeat a short smoke test through the normal shell/PATH entrypoint
- [ ] Keep 0.11.5 and its rollback instructions available during a settling period
- [ ] Update AGENTS.md, README.md, and LOG.md with the final supported version and upgrade procedure

- [ ] Remove 0.11.5 only after an explicit later decision
## Phase 13.9 — Consolidate on Neovim 0.12 native features
- [x] Keep lazy.nvim as the plugin manager; do not combine the runtime upgrade with a migration to experimental `vim.pack`
- [ ] Replace `mbbill/undotree` with the optional native `nvim.undotree` package while preserving `<leader>u`
- [ ] Trial native automatic/LSP completion with explicit selection and built-in snippet expansion
- [ ] Enable Copilot inline suggestions with a distinct accept key and hide them while the native completion menu is visible

- [ ] Remove nvim-cmp, cmp-nvim-lsp, cmp-buffer, cmp-path, LuaSnip, and copilot-cmp only after the native workflow passes
- [ ] Remove obsolete completion integrations, lockfile entries, highlights, and documentation
- [x] Remove nvim-cmp, cmp-nvim-lsp, cmp-buffer, cmp-path, LuaSnip, and copilot-cmp from the 0.12 candidate
