 - 2026-10-27: Updated `AGENTS.md` status and LSP architecture notes to reflect completed colorscheme work and the current Phase 12 implementation.
 - 2026-10-27: Added Conform's built-in `ruff_format` for Python. Ruff was already Mason-managed for diagnostics; this closes a gap where documentation claimed Python formatting but format-on-save had no Python formatter and disabled LSP fallback.
 - 2026-10-27: Fixed `<C-6>` in netrw when no previous real-file buffer has been recorded. Buffer classification now rejects `nil`, non-numeric, and non-positive buffer identifiers before calling Neovim's buffer API, allowing the mapping to fall back safely.
+- 2026-10-27: Removed Oil.nvim after workflow evaluation. Netrw is now the sole tree browser and file explorer, preserving the same navigation model on remote systems; Telescope remains dedicated to fuzzy finding. Removed Oil's plugin spec, lockfile entry, keymaps, colorscheme groups, and active documentation.
+- 2026-10-27: Planned the next work in two ordered phases. Phase 13 upgrades the standalone Neovim installation from 0.11.5 to stable 0.12.6 using versioned installations, isolated plugin testing, an unchanged initial lockfile, and an immediate rollback path; plugin updates follow only after core compatibility, and Mason tools remain a later step. Phase 14 then adds netrw-only live previews and read-only directory summaries against the validated 0.12 runtime.
+- 2026-10-27: Recorded the pre-upgrade rollback baseline: Neovim 0.11.5, 28 active lazy.nvim plugin specs after Oil removal, 32 compiled Treesitter parser binaries, clean headless startup, all active Lua files parsing, and `git diff --check` passing. The standalone 0.11.5 installation remains untouched under `/opt/neovim/nvim-linux-x86_64`.

+## Phase 13.1 — Confirm scope and upgrade policy
+- [ ] Confirm scope and priorities for this phase
+- [x] Target the current stable release: Neovim 0.12.6
+- [x] Continue using the official standalone Linux archive; do not hand Neovim management to pacman
+- [x] Keep Neovim 0.11.5 available until the upgraded setup has passed normal-use validation
+- [x] Separate the Neovim upgrade, plugin update, and Mason tool update into independently testable steps

+- [x] Record the current Neovim version, plugin lockfile, parser state, and startup result
+- [x] Confirm the existing 0.11.5 configuration still passes its automated checks
+- [x] Do not remove or overwrite the working 0.11.5 installation
+
+## Phase 13.3 — Audit 0.12 compatibility before switching
+- [ ] Review the Neovim 0.12 breaking changes against the active configuration
+- [ ] Replace deprecated `vim.loop` usage with `vim.uv`
+- [ ] Replace deprecated diagnostic navigation APIs with the current diagnostic jump API
+- [ ] Revalidate native `exrc` behavior now that 0.12 searches parent directories
+- [ ] Verify `vim.secure.read()` behavior in the project-local LSP settings loader
+- [ ] Determine how Neovim 0.12's built-in directory buffers interact with opt-in legacy netrw
+- [ ] Explicitly load netrw with `:packadd netrw` from Lua if 0.12 no longer loads it automatically
+- [ ] Check for conflicts or redundancy with Neovim 0.12's built-in `:Undotree`; do not remove the plugin without a separate decision
+
+## Phase 13.4 — Install Neovim 0.12.6 alongside 0.11.5
+- [ ] Download the official `nvim-linux-x86_64.tar.gz` release archive
+- [ ] Verify the archive against the SHA-256 digest published with the release
+- [ ] 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
+
+Proposed layout:
+
+```text
+/opt/neovim/nvim-0.11.5/
+/opt/neovim/nvim-0.12.6/
+/opt/neovim/current -> nvim-0.11.5
+```
+
+## Phase 13.5 — Test 0.12 with the existing plugin lockfile
+- [ ] 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
+- [ ] Validate headless startup and capture startup time
+- [ ] Run `:checkhealth` and review every relevant warning/error
+- [ ] Verify netrw can be loaded and `:Explore` opens the expected tree browser
+- [ ] Fix core/config compatibility issues before updating plugins
+
+## Phase 13.6 — Update plugins in isolation
+- [ ] Use a temporary branch or worktree based on the rollback checkpoint
+- [ ] Run lazy.nvim updates only inside the isolated 0.12 test environment
+- [ ] Review every lockfile change before adopting it
+- [ ] Prioritize lazy.nvim, nvim-lspconfig, Treesitter, Telescope, Mason integration, completion, formatting, linting, UFO, and Copilot compatibility
+- [ ] Rebuild or update Treesitter parsers for the 0.12 runtime and verify custom queries
+- [ ] Keep Mason-managed language servers, formatters, and linters pinned during this step
+- [ ] Adopt the tested lockfile only after all plugin-level regressions are resolved
+
+## Phase 13.7 — Validate the complete 0.12 candidate
+- [ ] Validate startup, lazy loading, commands, and keymaps
+- [ ] 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
+- [ ] Validate nvim-cmp, LuaSnip, and Copilot completion
+- [ ] Validate conform format-on-save and nvim-lint/Ruff diagnostics
+- [ ] Validate Treesitter highlighting, text objects, autotag, folding, and custom HTML/CSS queries
+- [ ] Validate the Paper Tonic colorscheme, plugin highlights, sessions, persistent undo, and shell templates
+- [ ] Perform interactive smoke tests in the PHP validation workspace
+
+## 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 — Update external tools separately
+- [ ] Review Mason package updates only after Neovim and plugin revisions are stable
+- [ ] Update language servers, formatters, and linters in small groups
+- [ ] Revalidate PHP, JavaScript/TypeScript, HTML/CSS, Markdown, Lua, and Python after each group
+
+## Phase 14 — Netrw Live Preview and Directory Summaries
+
+## Phase 14.1 — Confirm the final interaction model
+- [ ] Confirm scope and priorities for this phase after the 0.12 upgrade
+- [x] Keep netrw as the sole tree browser and file explorer
+- [x] Keep `p` as the preview entry point so stock-netrw muscle memory remains useful on remote systems
+- [x] Once a native preview window exists, update it automatically as the netrw cursor moves
+- [x] Close the preview automatically when a file is opened for editing or netrw is left
+- [x] Treat the existence of the preview window as state; avoid a separate global preview-mode flag
+
+Target workflow:
+
+```text
+p on file/directory  open preview and begin live updates
+j / k                replace preview with the selected entry
+<CR>, o, v, t        open the file and close the preview
+:pclose / <C-w>z     close the preview and stop live updates
+```
+
+## Phase 14.2 — Revalidate netrw integration on Neovim 0.12
+- [ ] Confirm the netrw version and its documented `netrw#Call()` bridge
+- [ ] Confirm `NetrwGetWord`, `NetrwBrowseChgDir`, and `NetrwPreview` remain available
+- [ ] Confirm tree paths, symlinks, directory markers, local paths, and URI paths are classified correctly
+- [ ] Resolve any interaction with Neovim 0.12's built-in `filetype=directory` buffers
+- [ ] Keep a graceful stock-netrw fallback if enhanced preview setup cannot be installed
+
+## Phase 14.3 — Implement live preview lifecycle
+- [ ] Extend netrw's buffer-local `p` behavior without changing its familiar purpose
+- [ ] Add a narrowly scoped, buffer-local `CursorMoved` autocmd
+- [ ] Debounce preview updates by approximately 75–100 ms
+- [ ] Update only when a preview window exists in the current tab
+- [ ] Continue using netrw's native preview machinery for regular files
+- [ ] Close the preview when leaving the netrw buffer to edit a file
+- [ ] Cancel and close pending timers when the netrw buffer is wiped out
+- [ ] Avoid focus changes: keep the cursor in the tree while previews update
+
+## Phase 14.4 — Add read-only directory summaries
+- [ ] Show an informational scratch-buffer preview when the selected entry is a directory
+- [ ] List immediate children only; do not calculate recursive directory sizes
+- [ ] Sort directories first and files second, alphabetically within each group
+- [ ] Show entry type, human-readable file size, modification time, and name
+- [ ] Show a summary count and total size for immediate files
+- [ ] Cap output at approximately 200 entries and show a truncation notice
+- [ ] Handle empty, missing, unreadable, and rapidly changing directories without errors
+- [ ] Display symlinks distinctly without recursively following directory links
+- [ ] Mirror netrw's hidden-file visibility where practical
+- [ ] Support local filesystems when Neovim itself is running over SSH
+- [ ] Fall back to native behavior for remote netrw URI schemes if directory enumeration is unavailable
+
+Example directory preview:
+
+```text
+lua/plugins/
+
+Type  Size     Modified          Name
+dir   —        2026-10-27 11:42  helpers/
+file  4.8K     2026-10-27 13:10  lsp.lua
+file  3.2K     2026-10-27 12:55  telescope.lua
+
+1 directory, 2 files, 8.0K
+```
+
+## Phase 14.5 — Test preview behavior
+- [ ] Test file → file, file → directory, directory → file, and directory → directory movement
+- [ ] Test directory expand/collapse while a preview exists
+- [ ] Test manual preview closure and confirm cursor movement no longer previews
+- [ ] Test `<CR>`, horizontal split, vertical split, and tab selection cleanup
+- [ ] Test separate preview windows across tabpages
+- [ ] Test spaces, Unicode, symlinks, unreadable entries, deleted entries, and large directories
+- [ ] Test rapid cursor movement for flicker, stale timers, and excess filesystem work
+- [ ] Test the workflow in an actual SSH session
+- [ ] Confirm stock netrw remains understandable when this configuration is unavailable
+
+## Phase 14.6 — Document and finalize
+- [ ] Update README.md and `:KeymapsGuide` with the enhanced `p` lifecycle
+- [ ] Record implementation decisions and limitations in LOG.md
+- [ ] Mark Phase 12.4 netrw preview validation complete after interactive use

@@ -518,4 +680,4 @@ Decisions & Changes:
 - **Project config format**: `.nvim.lua` files return `{ lsp = { [server_name] = { settings = {...} } } }`.
 - **Security model**: `secure` mode prompts user to trust `.nvim.lua` files before execution (one-time per file hash).
 - **Settings loading**: An `LspAttach` callback securely reads project settings from the client's actual `root_dir` (not cwd), ensuring correct behavior across different workspace structures.
-- **Phase 4 Navigation Strategy**: Skipped Neo-tree in favor of built-in netrw for visual context and project structure browsing. Telescope for fuzzy finding. Oil.nvim for file manipulation (evaluation phase; alternative is mini.files). Rationale: User needs visual context and preview, not per-tab roots or complex tree features. File manipulation primarily done in shell, but Oil.nvim handles buffer sync issues when renaming/moving files.
+- **Phase 4 Navigation Strategy**: Use built-in netrw as the sole tree browser and file explorer so the workflow transfers to remote systems. Telescope remains the fuzzy finder. Oil.nvim was evaluated and removed because maintaining a second explorer split muscle memory without providing the preferred tree view.
