yvgude/lean-ctx v3.6.11 on GitHub

Fixed

Linux proxy restart loop (11258+ restarts) — When the lean-ctx binary is replaced during runtime (e.g. upgrade), Linux marks /proc/self/exe with (deleted) suffix. find_binary() in the systemd unit generator would write this corrupted path into ExecStart, causing systemd to pass (deleted) as a CLI argument on every restart. Now uses resolve_portable_binary() which strips the suffix. Additionally, the CLI dispatch defensively removes (deleted) from args if already present in existing units (webut report)
Windows ctx_read hangs — Session lock acquire and path canonicalization now have bounded timeouts (5s for RwLock, 2s for canonicalize()) preventing indefinite hangs on Windows reparse points and network paths (Butetengoy report)
Manifest generator uses stale tool_defs — gen_mcp_manifest now reads from ToolRegistry (61 tools) instead of static granular_tool_defs() (56 tools), ensuring the website manifest always reflects the actual registered tool count

Changed

Context budget auto-escalation — pressure_downgrade() now applies more aggressive mode downgrades based on ContextPressure: SuggestCompression downgrades auto→map, ForceCompression downgrades full→map and auto|map→signatures
Cache-stable LITM output — Dynamic session statistics (ACTIVE SESSION v…) moved from output prefix to suffix, preserving a stable prefix for LLM prefix-caching compatibility
ToolRegistry as SSOT for list_tools — list_tools handler now reads tool definitions from the registry instead of static tool_defs/, eliminating schema drift between exposed schemas and handler implementations
OnceLock for project root — find_project_root() result cached via std::sync::OnceLock, eliminating repeated git rev-parse subprocess calls
Compaction sync tail-seek — find_latest_compaction() reads only the last 4KB of context_radar.jsonl instead of the entire file, bounding I/O for large radar logs

Removed

Dead code cleanup: removed unused functions, #[allow(dead_code)] attributes replaced with _ prefixes or deleted across 8 files

Upgrade

lean-ctx update                 # recommended (auto-downloads + refreshes shell hooks)
cargo install lean-ctx          # or
npm update -g lean-ctx-bin      # or
brew upgrade lean-ctx

Note: After upgrading via cargo/npm/brew, run lean-ctx setup to refresh shell aliases. lean-ctx update does this automatically.
