Thanks for the report — "LSP drops silently when AFT is enabled" is a symptom we take seriously, and the enabled: false part not healing it is surprising enough that we'd like to pin your exact setup. Could you attach:

1. The plugin log: ~/.local/share/cortexkit/aft/logs/aft-plugin.log (or under $XDG_DATA_HOME if set) — the last ~200 lines from a session where LSP was missing.
2. Which LSP integration you mean: OpenCode's own language-server features disappearing (hover, diagnostics from the editor side), or AFT's diagnostics (the aft_inspect diagnostics category / status bar counts)?
3. npx @cortexkit/aft doctor output on the affected machine (it prints binary/plugin versions and LSP server detection).
4. Your opencode.jsonc plugin entry and any .cortexkit/aft.jsonc in the affected project (redact anything private).

One known interaction to rule out: AFT spawns its own language servers for diagnostics (rust-analyzer, tsserver, pyright) — it does not attach to or replace OpenCode's LSP, so a conflict there would be news to us and the log will show it. If enabled: false genuinely didn't restore LSP after a restart, that points away from AFT's runtime and toward config/install state, which the doctor output will show.
