+# Handover -- 2026-04-03
+
+## Session Summary
+
+This session focused on getting **PR #754** (`feat: KG-boosted file search with ExternalScorer trait`) through CI and merged.
+
+### Tasks Completed
+
+1. **Fixed fff-search dependency** -- replaced local filesystem path with git dependency pointing to `AlexMikhalev/fff.nvim` fork branch `feat/external-scorer`
+2. **Created ExternalScorer trait** in the fork at `/tmp/fff-nvim-fork/crates/fff-core/src/external_scorer.rs`, pushed to `AlexMikhalev/fff.nvim` branch `feat/external-scorer`
+3. **Fixed u64 ID type migration** -- PR code used `String` IDs but main had refactored to `u64` (commit `9c8dd28f`). Updated `kg_scorer.rs`, `kg_scoring.rs` benchmark, `test_find_files.rs`, `watcher.rs`
+4. **Fixed pre-existing llm_router test failures** -- tests had `llm_enabled: false` but expected `Some` from `build_llm_from_role`
+5. **Fixed clippy warnings** -- `unnecessary_sort_by`, `len_zero`
+6. **Added zlob feature flag** -- created `zlob` feature in `terraphim_file_search` and `terraphim_mcp_server` Cargo.toml that forwards to `fff-search/zlob`
+7. **Updated CI workflow** -- added `--features zlob` to clippy, check, and test commands in `.github/workflows/ci-pr.yml`
+8. **Upgraded Zig on bigbox** -- from 0.9.1 to 0.15.2 (required by zlob 1.3.0) at `/usr/local/bin/zig` symlinked to `/usr/local/zig-x86_64-linux-0.15.2/zig`
+9. **Merged PR #754** and created **release v1.17.0**
+
+### Current State
+
+- **Branch**: `main` at `28017c38` (merge commit for PR #754)
+- **Tag**: `v1.17.0` pushed to both GitHub and Gitea
+- **GitHub release**: https://github.com/terraphim/terraphim-ai/releases/tag/v1.17.0
+- **All CI checks green**: format, clippy, compilation, tests, WASM, security audit
+
+### Uncommitted Work
+
+- **`crates/terraphim_multi_agent/`** -- 4 files modified (Cargo.toml, lib.rs, pool.rs, registry.rs). These are unrelated to this session's work.
+- **Stash `stash@{0}`** -- WIP from `feat/fff-kg-boosted-file-search` branch containing `test(config): add hash performance benchmarks for ahash validation`. May be worth reviewing.
+
+### Infrastructure Changes
+
+- **Zig 0.15.2** installed on bigbox at `/usr/local/zig-x86_64-linux-0.15.2/zig` (symlinked from `/usr/local/bin/zig`). Old versions remain:
+  - `/usr/local/zig-linux-x86_64-0.9.1/` (original)
+  - `/usr/local/zig-linux-x86_64-0.13.0/` (intermediate attempt)
+  - These can be cleaned up with `sudo rm -rf /usr/local/zig-linux-x86_64-0.{9.1,13.0}/`
+
+### Key Files Modified in PR #754
+
+| File | Change |
+|------|--------|
+| `crates/terraphim_file_search/` | New crate: KgPathScorer, KgWatcher, benchmarks |
+| `crates/terraphim_mcp_server/src/lib.rs` | Added find_files/grep_files MCP tools |
+| `crates/terraphim_mcp_server/tests/test_find_files.rs` | New integration tests |
+| `crates/terraphim_mcp_server/Cargo.toml` | Added fff-search git dep + zlob feature |
+| `crates/terraphim_file_search/Cargo.toml` | New, git dep on AlexMikhalev/fff.nvim fork |
+| `.github/workflows/ci-pr.yml` | Added `--features zlob` to cargo commands |
+| `crates/terraphim_service/src/llm.rs` | Fixed pre-existing llm_router test failures |
+
+### External Dependencies
+
+- **`AlexMikhalev/fff.nvim`** fork, branch `feat/external-scorer` -- contains the `ExternalScorer` trait needed by `terraphim_file_search`. If the upstream `dmtrKovalenko/fff.nvim` adds this trait, the fork dependency can be replaced.
+
+### Known Issues / Follow-ups
+
+- The `terraphim_multi_agent` uncommitted changes should be reviewed and either committed or discarded
+- Old stashes (14 total) could be cleaned up
+- Old Zig installations on bigbox can be removed
+- The fff.nvim fork dependency is pinned to a branch -- consider tagging a release on the fork for stability
