Subject: [PATCH 2/8] Resync with graphify-py @ 92e682f

Port the applicable feature, security, and bug-fix changes from
`graphify-py` v0.8.49 -> v0.9.0 (38 upstream commits) and bump the
workspace to `0.9.0`.

Ports:

- Node IDs are now the full repo-relative path with the extension
  dropped and separators collapsed to `_`, so same-named files in
  different directories stay distinct (#1504, #1509). Legacy graphs
  read as-is with a one-line rebuild nudge.
- Cross-file type-reference stubs are sourceless and carry an
  `origin_file` so same-label stubs from different files do not merge
  (#1462, #1500).
- New C# cross-file type resolver plus `enum`/`struct`/`record` node
  types (#1466).
- Java `enum`/annotation node types, generic-argument and field-type
  references (#1512, #1510, #1485, #1487).
- Objective-C header routing, generic property types, class-method
  selectors, and `@import` handling (#1475).
- New WPF/XAML extractor: `x:Class`, named controls, `{Binding}`
  paths, and ViewModel / code-behind resolution (#1460, #1473).
- Vue single-file-component extraction and `.metal` routing through
  the C++ extractor (#1468, #1480).
- Obsidian export only overwrites notes it owns via a manifest, the
  Canvas uses a `ceil(sqrt(n))` grid, and note/canvas filenames are
  de-duplicated case-insensitively (#1506, #1452, #1453).
- Wiki articles link with portable relative Markdown links instead of
  `[[wikilinks]]`, with case-folded slug dedup (#1444, #1453).
- LLM requests send `stream: false`, and `kimi`/`gemini`/`deepseek`
  honour a bare `*_BASE_URL` (#1223, #1458).
- CLI `--timing` on `extract`/`cluster-only`/`label`, and
  `--missing-only` on `cluster-only`/`label` (#1490, #1481).
- `reflect --if-stale` also weighs the graph sidecars, the Read|Glob
  hook matches a file's real trailing extension, and `affected` /
  `explain` resolve a source-file path to its file-level node
  (#1470, #1463, #1503).

Glory to the Omnissiah

+//! Node-ID migration for the #1504/#1509 full-path stem rule.
+//!
+//! The node-ID stem is now the full repo-relative path (`docs/v1/api/README.md`
+//! → `docs_v1_api_readme`) instead of just the immediate parent dir + filename
+//! (`api_readme`). The semantic cache is **unversioned**, so a cached/LLM
+//! fragment can still carry a pre-migration short id. [`apply_semantic_rekey`]
+//! deterministically re-derives every non-AST node's id from its own
+//! `source_file` so a drifted fragment reconciles with the AST node instead of
+//! spawning a ghost / a re-bill, and [`register_legacy_id_aliases`] registers
+//! the old-stem forms as edge-resolution aliases so a stale edge endpoint from
+//! an un-re-keyed fragment still resolves to the migrated node.
+//!
+//! `graphify-build` is the dependency leaf (`graphify-extract` depends on
+//! [`normalize_id`]), so the canonical `file_stem`/`make_id` in
+//! `graphify-extract::ids` cannot be imported here. The two tiny helpers below
+//! recompute the same recipe on top of [`normalize_id`]; the observable node
+//! IDs they produce are pinned by the build/extract parity tests, so any drift
+//! from `extract::ids` fails loudly rather than silently.

+//! WPF/XAML structural extractor (#1460, #1473).
+//!
+//! Mirrors `graphify-py/graphify/extract.py::extract_xaml` and its helpers.
+//! Extracts the root element, `x:Class`, named controls + their control types,
+//! `{Binding}` paths/commands/converters, bridges the view to its `.xaml.cs`
+//! code-behind by resolving event-handler attributes to the matching methods
+//! (gated on the .NET handler signature), and resolves the view to its
+//! ViewModel via an explicit `DataContext`, a design-time `d:DesignInstance`,
+//! the `View`→`ViewModel` naming convention, or Prism `AutoWireViewModel`. Also
+//! surfaces CommunityToolkit `[ObservableProperty]`/`[RelayCommand]` generated
+//! members. Uses stdlib XML (`quick-xml`) with the same size/DOCTYPE guards as
+//! the `.csproj` extractor.
+
+// WPF/XAML domain terms (ViewModel, CommunityToolkit, DataContext, …) read
+// naturally in prose; backticking every mention hurts readability here.

+//! C# cross-file type-reference resolution.
+//!
+//! Mirrors Python `graphify/extractors/csharp.py::_resolve_csharp_type_references`
+//! — the C# counterpart to the Java resolver. It re-points dangling
+//! `inherits`/`implements`/`references` edges that bare-name resolution left on
+//! sourceless shadow stubs to the real definition, disambiguating same-named
+//! types in different namespaces via each referencing file's `using` directives
+//! and enclosing namespace. Ambiguous matches are refused rather than guessed
+//! (the god-node guardrail).
+//!
+//! C# deltas from Java: a plain `using N;` is NAMESPACE-WIDE (resolve a bare
+//! `T` by trying `(N, T)` for each open namespace and accepting only a UNIQUE
+//! hit), while `using X = N.T;` is a single-type alias. `global using` is
+//! normalised (the `global` prefix stripped); `using static N.T;` is ignored
+//! (it imports members, not a namespace/type). The global namespace is keyed as
+//! the bare label. A file with MULTIPLE namespace blocks does not register its
+//! defs (which namespace each def belongs to needs source-range tracking) —
+//! deferred.

Subject: [PATCH 3/8] Address CodeRabbit review findings

Resolve the 24 findings from the first CodeRabbit pass on the resync.
Genuine divergences from graphify-py are fixed; findings that match
graphify-py are kept and the rationale recorded in an in-code comment
(CodeRabbit reads code, not commit messages).

Fixes:

- `extract()` now clears the thread-local XAML `ViewModel` class cache
  per run (generation-gated across the rayon pool), matching graphify-py
  `_XAML_CSHARP_CLASS_CACHE.clear()`; a repeated in-process run re-scans
  `.cs` instead of serving stale members. Adds a regression test.
- Obsidian manifest write propagates IO errors instead of swallowing
  them, like the sibling note writes and graphify-py `.write_text`.
- `ingest` C-family map includes `.cxx` (extracted as C++ and present in
  `analyze`'s family map; graphify-py's build map omits it).
- Legacy-id alias registration is skipped unless the node id shares the
  new stem, so a mismatched prefix no longer maps unrelated edges.
- `collect_cs_files` uses `entry.file_type()` so a symlinked directory
  cannot loop forever.
- `is_objc_header` reads only the 256 KiB it inspects.
- Vue dynamic-import recovery scans the masked source, so an `import()`
  in `<template>`/`<style>` is not edged.

Kept as graphify-py parity (documented in code):

- Sourceless stub `source_location` stays `Some("")` (graphify-py emits
  `""`); wiki resolver keys by label and reserves `index` only in the
  resolver; C# merges a file's namespaces into one scope; the direct
  `<Binding Path>` element emits no generated-member edge; validation
  runs once before the semantic re-key.

Also strengthens the affected test assertions (exact set/count checks,
`origin_file` and canonical-id checks, real absolute/relative paths, raw
event-edge count, loud directory-walk errors).

By the will of the Machine God

Subject: [PATCH 4/8] Address second CodeRabbit review round

Resolve the findings from the second CodeRabbit pass. Genuine bugs and
determinism gaps are fixed (several are bugs `graphify-py` shares, fixed
per AGENTS.md); findings that faithfully mirror `graphify-py` are kept,
with the parity reasoning recorded in code.

Fixes:

- `with_xaml_extract_root` restores the thread-local extract root through
  an RAII guard, so a panic can't leak it to a reused rayon worker
  (parity with graphify-py's `try`/`finally`).
- `.xaml` joins the AST disk-cache bypass list: XAML resolution scans
  sibling `.cs` code-behind, so a content-keyed cache served stale
  `ViewModel` members across runs.
- `origin_file` is relativized alongside `source_file` (extraction and
  build) so the #1462 stub field no longer leaks absolute machine paths
  into graph JSON.
- objc and PowerShell `ensure_named_node` emit sourceless stubs (empty
  `source_file`, `origin_file` set) so cross-file references rewire onto
  real definitions instead of becoming phantom duplicates (#1402/#1462).
- Obsidian `owned_write` refuses to follow a symlink at the target or a
  parent component, so a symlinked note can't escape the vault (#1506).
- `find_node` matches a source path by its normalized full path rather
  than tokenized form, so distinct paths no longer collide.
- `cluster-only --missing-only` preserves a malformed labels file instead
  of relabeling over it, matching the non-`--missing-only` path.
- `#[must_use]` on the pure ID/stem helpers; corrected `extract` and
  `label` doc-comments.

Kept as parity (documented in code): the objc compound-selector node-ID
form, C# nested-namespace registration deferral, and the wiki/`index_md`
god-node list all mirror `graphify-py` exactly.

Test strengthening: `lessons_fresh` now covers both graph sidecars
(matching the Python parametrization), the trailing-slash seed test
exercises the re-keyed file node, and the affected test suites return
`Result` with `?` per the repo convention.

By the will of the Machine God

Subject: [PATCH 5/8] Fix backslash path L1 preference in `find_node`
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A `src\foo.rs` query reached the `source_exact` tier (its `query_path`
normalizes `\` to `/`), but the L1 file-node preference never fired.
`query_basename` came from `Path::file_name` on the raw label, and on
Unix `\` is not a path separator, so the basename kept the whole
backslash string instead of `foo.rs` — so the file node never floated
ahead of its symbols. Derive both `query_basename` and `query_path`
from one slash-normalized string so Windows-style path queries match
the forward-slash behavior (#1503).

The `#[must_use]` nitpick on `find_node` was already satisfied; no
change there.

Subject: [PATCH 6/8] Document parity decisions for re-raised findings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three CodeRabbit findings (C# nested namespaces, ObjC selector colon
collapse, wiki `index_md` god-node list) were re-raised. Verified each
against `graphify-py @ 92e682f`: all faithfully mirror the reference,
none is a still-valid bug, and "fixing" any would break byte-identical
parity. No behavioral change — only inline parity notes:

- ObjC (`objc.rs`): graphify-py joins selector identifiers colon-less
  (`extract.py:9623`/`:9657`), pinned by `objc_compound_selector_call_
  resolves`. Firmed the comment to name the deliberate collision-risk
  trade-off (`setFoo:bar:`/`setFoobar:` collapse); preserving `:` would
  re-key every keyword selector and break parity.
- Wiki (`generate.rs`): `index_md` intentionally gets the full
  `god_nodes_data` (`wiki.py:333`); a node absent from the graph is
  rendered as plain text by `md_link`, not a broken link, so filtering
  would diverge from byte-identical `index.md`. Documented at the call
  site.

The C# site was already documented (`csharp.py:106-111`, flat `own_ns`
with `# len > 1: skip`); left unchanged.

Subject: [PATCH 7/8] Preserve labels under `--no-label --missing-only`

`cluster-only --no-label --missing-only` with an existing
`.graphify_labels.json` wiped every community to a `Community N`
placeholder, clobbering hand-curated names. The `--no-label` branch
fired before the `--missing-only` handling and never loaded the
existing file.

graphify-py preserves here: `__main__.py:3489` loads existing labels
for any `exists && !force_relabel` case, with no `missing_only`
exclusion. The Rust port had added `&& !opts.missing_only` to that
branch, dropping `--no-label --missing-only` into the placeholder path.

Fire the preserve branch whenever no LLM naming will happen
(`!missing_only || no_label`), since `--no-label` forbids any LLM call.
Curated labels survive; only true gaps fall back to placeholders. Adds
a `cluster-only` regression test.

Subject: [PATCH 8/8] Fix export timing stage; strengthen label tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Address the latest CodeRabbit findings (verified against
`graphify-py @ 92e682f`):

- `cluster-only` marked the `export` stage before the HTML render, so
  `--timing` excluded `to_html` time. graphify-py marks it after
  (`__main__.py:3555`); moved the mark past the render to match.
- Strengthened the label-preservation tests to assert community 0
  still maps to `Authentication` by key (parse + `["0"]`), not a bare
  substring; added a concrete per-stage line to the timing test. Adds
  `serde_json` as a dev-dependency for the structural assertion.

Skipped (parity): the `--no-label` branch keeps `&& !force_relabel` —
`label` does not accept `--no-label`, so the combination is
unreachable, and the guard matches graphify-py `__main__.py:3494`
(`elif no_label and not force_relabel`).
