v0.23.3

On PyPI as cg-code-graph (pipx install cg-code-graph).

Added

• Swift: a call that leaves out a defaulted argument gets its own CALLS edge to what the default calls, at the call site, with attrs.omits_default (the parameter label) and attrs.default_of. impact on the default's callee lists the callers that omit the argument (through an omitted default argument) and not those that pass it; callers labels them (runs the default of gamut: in render) and the declaration edge (parameter default gamut:) (#212, Swift part).

Changed

• impact and callers count selector-only candidates (receiver type unknown, #83) apart from resolved callers: transitive callers: 3 (+1 candidate), direct callers: 2 (2 sites); candidate callers: 1 (1 site, ...), and callers_resolved / callers_candidate in the JSON. Candidates show their fan-out ((candidate, 1 of 3 methods named refreshStatus), candidate_of in JSON) and are left out of callers by module. A caller without a module (a free function) is grouped as <file> (top level) instead of ? (#204).
• MCP node prints neighbours as <id> :<line>, so a per-platform variant reads refreshStatus@24 :12 instead of refreshStatus@24@12 (#201).
• tree-sitter-swift 0.7.4 is supported (pin lifted to <0.8): !Type.method() parses with the operator around the callee and is unwrapped; members after an unknown attribute macro parse without recovery. Every Swift fixture gives the same graph on 0.7.3 and 0.7.4; corpus differences are listed in docs/validation-log.md (#199, part).

Fixed

• Swift #if / #else variants: a reference made where only some targets build (a macOS-only caller or call) links only the per-platform definitions built on one of those targets, so a macOS-only call no longer reaches the #else stub and the stub no longer looks reached by macOS-only code. A reference whose definition is not built anywhere the site is moves to the sibling definition that is, and a #else type with no init of its own uses its implicit initializer instead of being bound to a sibling variant's init, so platform_divergence reports no false missing callee. References from code built everywhere still link every definition. callers counts a site linked to several variants once (#201).
• Swift exact mode keeps the default_arg mark on a parameter default's call, so impact does not walk the declaring function as an unconditional caller (#208).
