 - [ ] Verify neoconf merges settings into lspconfig
 - [x] Wire `intelephense.environment.includePaths` via `.neoconf.json`
 - [x] Create validation workspaces: `WORKSPACE_TEST/` and `EXTERNAL_TEST/` with sample PHP files
+- [x] Enable LSP debug notifications during validation and remove them after verifying roots
+
+## Phase 3.7 — Clean LSP config
+- [x] Remove debug/helper logic from LSP config
+- [x] Use non-deprecated per-server setup (no top-level lspconfig table access)
+
+## Phase 3.8 — Validate Neoconf includePaths (temporary)
+- [x] Temporarily inject `intelephense.environment.includePaths` via lspconfig for `WORKSPACE_SIMPLE` to validate goto-definition
+- [x] After validation, remove the temporary injection and rely on neoconf
 
 ## Phase 3.5 — LSP minimal defaults
 - [x] Add `nvim-lspconfig` with minimal defaults (no over-configuration)
+- [x] Add minimal LSP on-attach keymaps (gd, gr, K, gD, gI)
+- [x] Add global LSP keymaps with fallback in `lua/keymaps.lua`
+
+## Phase 3.6 — LSP server management (Mason)
+- [x] Confirm scope and priorities for this subphase
+- [x] Add `williamboman/mason.nvim` and `williamboman/mason-lspconfig.nvim`
+- [x] Ensure servers installed: `lua_ls`, `tsserver`, `html`, `cssls`, `jsonls`, `bashls`, `marksman`, `intelephense`
+- [x] Keep our custom per-server setup; use Mason only for installation
+- [x] Improve root detection to include `.neoconf.json`

 - Avoid adding plugins not listed in the guide unless explicitly requested.
 - Prefer simple defaults; only add settings that clearly improve workflow.
 - Plugin approval policy: unlisted plugins may be proposed, but must be explicitly confirmed before installation.

+Known Issues / Follow-ups:
+- lua-language-server (lua_ls) from Mason failed to start due to missing shared library `libbfd-2.38-system.so`. Options:
+  - Install lua-language-server via system package manager compatible with your distro.
+  - Provide the required `libbfd` or adjust symlink to match expected soname.
+  - Skip lua_ls for now; neoconf validation can be done with other servers (e.g., jsonls) and PHP (intelephense).

 - 2025-12-06: No direnv fallback for local config (keep setup simple and repo-driven).
 - 2025-12-06: Project-local config = layered JSON `.nvim.json` + `.nvim.local.json` with `.nvimroot` as workspace boundary marker (multi-repo friendly).
 - 2025-12-06: Switch to `folke/neoconf.nvim` for project-local configuration (supersedes custom layered JSON loader); use `.neoconf.json` at workspace root.
+- 2025-12-06: Use `mason.nvim` + `mason-lspconfig.nvim` to install/manage LSP servers; keep custom lspconfig setup; include `.neoconf.json` in root detection.
+  - For PHP validation inside this repo: we require `.neoconf.json` to attach `intelephense` to avoid the repo’s `.git` being chosen as the LSP root.
 - 2025-12-06: Plugin approval policy — other plugins are allowed, but do not install any plugin not listed without explicit confirmation.
