Three callback-registration shapes deferred from #756/#808, one arc:
1. INHERITED this.X (TS/JS + every this.-routed language): a `this.<member>`
registration whose member isn't on the enclosing class defers to a second
pass (resolveDeferredThisMemberRefs — in-memory like deferredChainRefs,
runs after implements/extends edges persist, same lifecycle as the #750
conformance pass) and resolves up the supertype chain, depth-capped BFS,
validated targets only. `bus.on("submit", this.handleSubmit)` in a
subclass links to FormBase::handleSubmit; same-named methods on unrelated
classes never match. this.-prefixed candidates skip the extraction name
gate (an inherited member can't be in definedHere).
2. JAVA/KOTLIN qualified method refs: `Handlers::onMessage` /
`OtherClass::handle` emit QUALIFIED names resolved by the scoped
suffix-matcher — cross-file capable, gated on the scope name being a
same-file type or an imported name (dotted JVM imports now contribute
their last segment). `this::m` and `super::m` route through the
class-scoped resolver (super rides the supertype pass). References
through a VARIABLE (`subscriber::onNext`) deliberately produce nothing —
receiver type is unknowable; RxJava's baseline bare capture was resolving
these to same-named same-file methods (a test method "registering" an
anonymous class's onNext) — the rework drops 18 such wrong edges and
keeps the 7 genuine Type::method refs RxJava's main tree actually has.
3. SWIFT enclosing-type scoping (implicit self): bare callback names match
methods only of the from-symbol's own type (extension/nested scopes
reconciled by suffix), and top-level code never matches methods.
Alamofire: −44 wrong edges (parameters like `request`/`data`/`retrier`
resolving to same-named methods on unrelated protocols), all verified;
the same-class param collision (`task`) remains and is documented.
New ResolutionContext.getNodeById lets matchers derive the from-symbol's
class scope. Controls: redis/fmt fnref edges byte-identical; excalidraw
stable; typeorm +4 genuine inherited-getter dependencies; zero calls edges
changed on any of 7 A/B repos; nodes identical everywhere. Kotlin
companion-object members extract unqualified (pre-existing) so
`Type::companionFn` stays silent rather than guessing — documented.
Full suite 1389 passed. EXTRACTION_VERSION 20 → 21 (re-index to benefit).
