+## 0.8.46 (2026-06-23)

 - Perf: graph queries on large graphs are faster via a trigram candidate prefilter in the MCP/CLI query path. A trigram→node index (built once per graph and rebuilt on hot-reload) narrows the candidate set before the IDF-weighted scorer runs, cutting the previous O(N) scan. The prefilter is a strict superset of the exhaustive scorer (it indexes `norm_label`, `label_tokens`, `nid`, and `source_file`), so results and ranking are unchanged; short/CJK queries and low-selectivity terms fall back to the full scan (#1431; thanks @papinto).
 - Feat: the skill runbook adds a Step 4.5 graph-health gate that runs `diagnose_extraction` and surfaces dangling/self-loop/collapsed-edge warnings before labeling, and anchors the semantic cache on the scan root (`root='INPUT_PATH'`) so cache hits survive a non-cwd scan. Read-only — never aborts the build (#1437; thanks @bahcgscateringsa-design).
 - Fix: `graphify install --platform hermes` now installs to the right directory on Windows. Hermes scans `%LOCALAPPDATA%\hermes\skills`, but the installer always used the POSIX `~/.hermes/skills` (so on Windows the skill was never discovered). `_platform_skill_destination` gained a hermes branch that targets `%LOCALAPPDATA%\hermes\skills` on Windows and keeps `~/.hermes/skills` elsewhere (#1403).
 - Fix: cross-file type-annotation references no longer create phantom duplicate nodes. A class defined once but referenced via type annotations in N other files (`def f(x: Thing) -> Thing`) produced 1+N nodes — the extra ones with the referencing file's path baked into the id (`pkg_a_py_thing`). `ensure_named_node` minted a *sourced* stub for these cross-file refs, which `_disambiguate_colliding_node_ids` then collided into per-file ids and `_rewire_unique_stub_nodes` refused to collapse. The fallback now emits a *sourceless* stub (like the inheritance-base path), so the references resolve to the single canonical definition. Fixed uniformly across all six language extractors that share the helper (#1402).
 - Feat: CUDA (`.cu`/`.cuh`) source files are now extracted. CUDA is a C++ superset, so these files route through the existing C++ (`tree-sitter-cpp`) extractor — no new grammar dependency. `__global__`/`__device__` kernels, host functions, structs and `#include`s are captured, host call edges are inferred, and `<<<grid, block>>>` kernel-launch syntax parses without error. Detection and file-watching follow automatically since both derive their extension sets from the dispatch table / `CODE_EXTENSIONS` (#1411).
+- Fix: `to_obsidian` / `to_canvas` no longer emit punctuation-only filenames (e.g. `@.md` from a `@/*` tsconfig `paths` key). Such a file is valid on disk but empty once a downstream tool re-slugs on word characters (it crashes `qmd update`), so an all-punctuation label now falls back to `unnamed` (#1409; thanks @Mylock51).
+- Fix: the opencode plugin's search reminder no longer contains backticks. The hook prepends the reminder inside a double-quoted `echo`, where bash performed command substitution on the backticks — silently running `graphify query "<question>"` on every search. The reminder is now plain text (#1413; thanks @WSHAPER).
+- Fix: `graphify extract --cargo` exits with a clear error instead of a traceback when `Cargo.toml` is missing or unreadable (the introspection now also catches `OSError`) (#1428; thanks @DhruvTilva).
+- Chore: resolve an `F821` (undefined `nx`) flagged in `prs.py` by importing `networkx` under `TYPE_CHECKING` for the quoted type annotation (#1429; thanks @DhruvTilva).
