+ *     it, that one whether the node sits INSIDE the head -- so there is one
+ *     definition of the head and they cannot drift apart. That containment
+ *     stops at the head rather than covering the whole `when` operator, which
+ *     is deliberate in the other direction: only the parameters being BOUND are
+ *     excluded, and a parameter READ in the guard is a reference, exactly as
+ *     the same read in the body is.
+ *   - extract_unified.c, compute_elixir_func_qn, resolves a def's QN to open
+ *     the function's call scope and reads the head through the same helper.
+ *     Handed the `when` operator instead it returns NULL, no scope is pushed,
+ *     and every call in a guarded body is sourced from the File rather than
+ *     from the enclosing Function. That failure is independent of the two above
+ *     because it decides edge SOURCE, not edge existence.
+ *
+ * Suppressing the head does not only delete edges; it moves metadata on edges
+ * that SURVIVE, and that is worth stating because a caller reading an edge's
+ * `line` will see a different number than before. `edges` is UNIQUE on
+ * (source, target, type), so where the def-head phantom happened to be the
+ * dedup survivor for a pair, deleting it promotes some other row for that same
+ * pair and the surviving edge takes that row's `line`.
+ *
+ * Measured by indexing one 970-file Elixir lib tree with the binary built from
+ * this commit's parent and with this one, and diffing the `edges` rows out of
+ * the two SQLite stores keyed on (source QN, target QN, type): 2,436 edges go
+ * and NONE is added -- 2,104 CALLS and 332 USAGE. Of the 119,696 edges that
+ * survive, 1,054 record a different `line`.
+ *
+ * The typespec attributes -- `@spec f(t) :: u` and the @callback / @type family
+ * -- put the declared name in a `call` node too, and are deliberately NOT
+ * suppressed here. A def head can be, because extract_usages.c already treats a
+ * def's first argument as a binding. Nothing there treats a typespec subject as
+ * one, so declining it in this walk would not remove its phantom, it would
+ * RELABEL it: handle_usages reaches the bare identifier handle_calls just
+ * declined and mints a USAGE onto the same function, which under
+ * UNIQUE(source, target, type) is a separate row that no longer collides with
+ * the real call it used to hide behind, and which pass_importance then counts.
+ * A typespec phantom has to be removed before any extractor sees it, by
+ * skipping the whole subtree in the unified walk. */

+// `def admin?(%__MODULE__{}), do: false` read back as a predicate that always
+// returns false. One node per function is right, so widen its span instead.
+//
+// Two bounds keep the widened span honest, and a clause folds only if it clears
+// both:
+//   - Same module body. `scope` is the do_block the previous clause was written
+//     in, so a nested `defmodule` cannot merge with its parent: the QN carries
+//     no module, so `Outer.run` and `Outer.Inner.run` compute the same name and
+//     are array-adjacent when Inner is declared just above Outer's own clause.
+//   - Same group. Only the immediately preceding EXTRACTED definition is a
+//     candidate, so a def of another name between two same-named defs ends the
+//     group. That is a bound this code imposes, not a guarantee Elixir gives:
+//     the compiler only WARNS ("clauses with the same name and arity should be
+//     grouped together"), it warns per name AND arity while this QN is
+//     arity-free, and non-contiguous clauses do compile. Split clauses
+//     therefore keep separate nodes, which is the pre-existing behaviour.
+//     What the group bound does NOT exclude is a non-definition construct
+//     between two clauses: `@doc` / `@spec` are unary_operators, `use` /
+//     `alias` / `describe` are ordinary calls, and a `defimpl` block's inner
+//     defs are not extracted -- none of them push a def, so anything of that
+//     kind written between two clauses of one function ends up inside the
+//     widened span, and that is not rare. Measured by indexing one 970-file
+//     Elixir lib tree with the binary built from this commit's parent and with
+//     this one and diffing the `nodes` rows out of the two SQLite stores: 6,996
+//     Function nodes widen their span, none is added, none is lost and none
+//     narrows. Reading each widened span for a module-body construct written at
+//     the module's own two-space indent, which no clause body reaches, 169 of
+//     the 6,996 cover such a line. Counting each node once per kind, 123 cover
+//     a typespec attribute (@spec/@type/@typep/@opaque/@callback/
+//     @macrocallback), 100 an @doc or @typedoc, 46 a bare comment line, 14 an
+//     @impl, and none a `use`, `alias`, `import`, `require` or a module-level
+//     `quote`. Swallowed typespecs are the largest attribute kind, not an
+//     absent one.
+//
+// The widened span also admits a phantom call that a narrower span kept out,
+// which is why the head suppression in extract_calls.c travels with this fold
+// rather than after it. cbm.c flags self-recursion by finding the innermost
+// Function whose [start_line, end_line] contains a recorded call whose short
+// name matches the function's own, so any pre-existing phantom between the
+// first and the last clause becomes a self-edge as soon as the span covers it.
+// That cost is real and is measured rather than asserted away. Same corpus,
+// reading each flagged node's own source span for any line that names it as a
+// call, a capture or a pipe target, counting a one-line clause's body after
+// `, do:` as such a line: self_recursive Function nodes go 129 -> 430, and the
+// ones carrying no self-call form anywhere in their span go 6 -> 48. The lines
+// responsible are the typespec heads the widened span now covers -- `@spec
+// f(t) :: u` puts the declared name in a `call` node, and the unified walk
+// reads it as code -- a separate defect with a separate fix, not something this
+// fold can close.
+//
+// Skipping the typespec subtrees, later in this stack, closes that half: the
+// same method then reports 389 self_recursive Function nodes and 8 with no
+// self-call form, against 129 and 6 on the base. All 8 are the pre-existing
+// phantom a local variable sharing the function's name mints (`defp slug(value)
+// do slug = ...`), 6 of them already present on the base; the other 2 are
+// guarded clauses that only have a node of their own to be flagged on because
+// of this stack.
+//
+// What the fold and the head suppression together remove is 2,436 edges, none
+// of them added back: see elixir_call_is_definition_role in extract_calls.c.
+//
+// A clause whose macro differs (`def` foo/1 beside `defp` foo/2) still folds,
+// because the arity-free QN already puts both on one node; is_exported is then
+// the OR over the folded clauses, so a name any clause exports stays exported.
+// That OR changes a recorded flag, which the node diff confirms and which is
+// worth stating rather than leaving to be discovered: on the same corpus
+// exactly 6 Function nodes change is_exported, all false -> true and none the
+// other way. Each is a `def` clause written above a `defp` clause of the same
+// name, where the pre-patch last-clause-wins record reported a publicly
+// callable name as unexported. Verified against the source in every one: the

+ *
+ * Measured on a fixture of three typespec lines (`@type state :: map()`, `@spec
+ * fetch(opts) :: state`, `@spec load(User.t()) :: :ok`) beside `def state`,
+ * `def opts` and a remote `MyApp.User.t/0`: seven edges, every one phantom and
+ * every one landing on a Function. CALLS onto each specified function;
+ * CALLS + USAGE + WRITES onto `state`, the WRITES asserting a mutation that
+ * does not exist; and USAGE onto `opts` and onto `MyApp.User.t/0`, because a
+ * bare or remote TYPE name resolves to the same-named FUNCTION. On a codebase
+ * whose convention is @spec on every public function, fan_in therefore never
+ * reaches 0 and "which exported functions nothing calls" is unanswerable.
+ *
+ * The whole subtree is skipped, not just the specified name. What that costs is
+ * not uniform across the six heads, and both halves were measured by indexing
+ * one fixture repo -- a declaring file per head plus the file each one reaches
+ * -- with the pristine binary and with this one:
+ *
+ *   spec, type, typep, opaque. A type reference resolves onto a FUNCTION or
+ *   onto nothing, never onto the type it names, because a type declaration
+ *   mints no node. `@spec build(MyApp.User.t())` where that module's `t` is a
+ *   `@type` produced no edge in either build, and `@type ext :: Ecto.Schema.t()`
+ *   naming a module outside the repo produced none either. The references that
+ *   do resolve land on a same-named Function, cross-file included -- `USAGE
+ *   lib/decl_type.ex -> Function type_target @lib/remote_type.ex`, and the
+ *   @typep and @opaque equivalents. A Function standing in for a Type is the
+ *   pollution rather than a record of it, so nothing correct is lost here.
+ *
+ *   callback, macrocallback. The declared name IS a function name, so it
+ *   resolves onto an implementation elsewhere in the corpus: pristine yields
+ *   `CALLS lib/decl_callback.ex -> Function callback_fun @lib/impl_callback.ex`
+ *   and the @macrocallback equivalent, both cross-file, and this build yields
+ *   neither. That edge does point at a real Behaviour-to-Impl relationship, and
+ *   nothing replaces it -- `@behaviour MyBehaviour` mints no edge of its own,
+ *   so after this change nothing in the graph links a behaviour to its
+ *   implementations. It is deleted anyway because it is name resolution and not
+ *   a behaviour model: on a fixture with one @callback and three same-named
+ *   `handle_it/1` defs, the single edge landed on the one module that
+ *   implements nothing, leaving both real implementors at fan_in 0. Recording
+ *   that relationship correctly means minting it from `@behaviour`, which is a
+ *   separate change and not a reason to keep an arbitrary edge.
+ *
+ * The other accepted cost: `unquote(...)` inside a typespec does execute at
+ * compile time, so `@type t :: unquote(build_type())` loses its genuine
+ * `build_type` call edge along with the phantoms.
+ *
+ * Only this family is skipped. Every other attribute VALUE is ordinary
+ * compile-time code -- `@timeout Application.compile_env(:app, :timeout)`
+ * really does call compile_env -- so those subtrees are walked exactly as
+ * before, and their attribute NAME is still emitted as a callee: `@behaviour
+ * GenServer`, `@timeout 5_000` and `@doc "x"` each still mint one phantom CALLS
+ * onto a same-named Function. That half of the defect class is untouched here
+ * and needs its own fix.
+ *
+ * This subtree skip is one of two mechanisms, and neither subsumes the other.
+ * It removes the phantom a typespec LINE mints; the def-head phantom is removed
+ * separately, by the calls walk recognising a `when`-wrapped head as a
+ * declaration (elixir_call_is_definition_role, extract_calls.c). A function
+ * carrying both an @spec and a `when` clause needs both: with only this one it
+ * keeps the def-head reference, with only the other it keeps the @spec one.
+ * `extract_elixir_typespec_attribute_is_not_code` pins that by asserting 0
+ * references onto such a function, so removing either mechanism fails it.
+ *
+ * Measured over forge-symphony-graph/lib (970 .ex files) by classifying the
+ * source line every CALLS/USAGE/WRITES edge records: a build without this skip
+ * anchors 4,565 CALLS edges on a typespec-attribute line, and this build
+ * anchors 0 -- with no USAGE or WRITES appearing in their place, which is what

+ * binary_operator whose left operand is the `name(args)` call, and Elixir
+ * admits more than one guard on a clause, which tree-sitter-elixir nests

+ * stays outside the binding, and the calls walk wants to know whether the node
+ * it is visiting IS that head or one of the guard operators above it.
+ *
+ * That last question is why cbm_elixir_def_head_is exists beside the unwrap,
+ * and it is exercised here on the AST rather than through cbm_extract_file
+ * because the two routes it has to answer for are indistinguishable from
+ * outside: `def f(x) when g` reaches the calls walk as the inner `f(x)` call,
+ * which the unwrap reaches, while `def f when g` has no inner call at all and
+ * reaches it as the `when` operator itself, which the unwrap does not. A test
+ * that only drives one walk sees whichever of the two that walk happens to hit.
+ *
