Thanks for the rebase — base OID is correct now (0581894b). However the branch still has a conflict with main in config.rs: the feature branch replaces the file wholesale and loses commit b64df991 (#698 — process-lifetime dedup of config deprecation warnings via EMITTED_CONFIG_WARNINGS / emit_config_warning_once). The PR diff shows those lines being deleted, and CI will fail because the revert also drops the tempfile dev-dep fix for runtime tests.

The feature additions (ConfigFileStatus, ConfigFileReport, ConfigInspection, inspect()) are the right direction. The fix needed: cherry-pick or manually re-apply the #698 changes on top of your feature branch so both coexist in config.rs. The specific lines to preserve from main:

use std::collections::{BTreeMap, HashSet};
use std::sync::Mutex;

static EMITTED_CONFIG_WARNINGS: std::sync::OnceLock<Mutex<HashSet<String>>> = std::sync::OnceLock::new();

fn emit_config_warning_once(warning: &str) { ... }

And change the eprintln! call back to emit_config_warning_once(&warning.to_string()).

Closing this for the same reason as #3098: the branch is still not reviewable. It has the same shape (+731/-2309 across only 3 files), CI is failing, and the diff still appears to revert recent main changes instead of presenting an LSP-only patch.

Please rebuild the branch from current origin/main and verify locally before opening a new PR: the net diff should preserve current main changes and contain only the LSP v2 additions.
