feat(vue): migrate Vue SFC to scope-based resolution (RFC #909 Ring 3, closes #940)

[ReidenXerx]

Summary

Closes #940. Migrates Vue Single-File Components to the RFC #909 Ring 3 scope-based resolution pipeline, making Vue the 14th language to reach registry-primary.

Vue <script> / <script setup> blocks are TypeScript — emitVueScopeCaptures extracts the script block via the existing extractVueScript utility and delegates to emitTsScopeCaptures, keeping grammar identity consistent with the cached parse tree the parse-worker already builds. No new tree-sitter grammar or native dependency is required.

---

Deliverables

All items from the issue spec are addressed:

Deliverable	Status	Notes
emitScopeCaptures — SFC parsing	✅	vue/captures.ts delegates to emitTsScopeCaptures via extractVueScript
interpretImport	✅	Reuses interpretTsImport (identical capture vocabulary)
resolveImportTarget adapter	✅	vue/import-target.ts — TS resolver + tsconfig path-alias support
receiverBinding — this in Options API	✅	Reuses tsReceiverBinding; fieldFallbackOnMethodLookup: true for untyped this
Shadow parity + flip	✅	Added to MIGRATED_LANGUAGES + SCOPE_RESOLVERS
Fixture set ≥ 30 cases	✅	38 test cases across 3 fixture repos

---

Architecture

emitVueScopeCaptures (captures.ts)

emitVueScopeCaptures(sourceText, filePath, cachedTree)
  → extractVueScript(sourceText)     // pure-function SFC extractor (existing)
  → emitTsScopeCaptures(scriptContent, filePath, cachedTree)

Positions are relative to the extracted script block, consistent with the cachedTree the parse-worker already builds from that content. No offset translation is needed — scope model positions are only used for within-file scope-containment walks, not for absolute graph-node line numbers (which come from the legacy parse-worker path).

vueScopeResolver (scope-resolver.ts)

Extends the TypeScript resolver with Vue-specific settings:

• fieldFallbackOnMethodLookup: true — Options API this.X() calls may not resolve through the type-binding layer when the component uses a plain object literal rather than a class. The field-fallback heuristic catches common patterns via declared field names.
• allowGlobalFreeCallFallback: false — Vue uses explicit ESM imports; workspace-wide unique-name fallback would produce spurious edges for compiler macros (defineProps, ref, computed, …) already covered by vueProvider.builtInNames.
• loadResolutionConfig — loads tsconfig.json path aliases (@/, ~/) since Vue projects universally use TypeScript.

makeVueResolveImportTarget (import-target.ts)

Delegates to resolveTsTarget with language: SupportedLanguages.TypeScript so:

• tsconfig path-alias rewriting fires (TS-language branch in resolveImportPath)
• .ts / .tsx extension-suffix fallback applies for bare imports (import { User } from './types')
• Explicit .vue imports (import Button from './Button.vue') resolve via the exact-path branch — no Vue-specific suffix guessing needed

---

Test fixtures

Three fixture repos covering the main Vue patterns:

vue-composition-api — <script setup lang="ts">

• UserProfile.vue — defineProps, ref, computed, cross-file fetchUser / saveUser / formatUser calls
• PostList.vue — defineEmits, ref, formatPost call
• App.vue — imports both components, ref, Post type binding

vue-options-api — defineComponent({ methods, computed, data })

• TodoList.vue — addTodo / toggleItem / clearDone methods calling imported createTodo / toggleTodo / filterDone / filterPending
• Counter.vue — increment / decrement / reset methods with props
• App.vue — Options API component registration

vue-cross-file — composables + class models

• models.ts — UserModel / PostModel classes with typed methods
• composables/useUser.ts — composable returning { user, loadUser, getDisplayName }, instantiates UserModel
• composables/usePost.ts — composable returning { post, loadPost, getSummary }
• components/UserCard.vue — calls useUser, destructures and calls loadUser, getDisplayName
• components/PostCard.vue — calls usePost, destructures and calls loadPost, getSummary
• App.vue — calls useUserList, addUser, new UserModel(...)

---

Known limitations (tracked in #1647)

1. Template expression calls — Bindings referenced inside <template> expressions (e.g. {{ formatDate(x) }}) are not resolved through the scope model. Component-reference CALLS edges continue to be emitted by the legacy template extractor in the parse worker.
2. Options API this resolution — this.X() inside Options API methods does not resolve through the type-binding layer when the component is a plain object (not a class). fieldFallbackOnMethodLookup recovers common patterns.
3. <script> + <script setup> dual-block — When both blocks are present, only <script setup> is processed per extractVueScript priority. The non-setup block is skipped (consistent with the rest of the pipeline).

---

Conformance

Vue SFC script blocks are ECMA-262 TypeScript/JavaScript. The scope-resolution pipeline is driven by the TypeScript grammar (same grammar as the existing TypeScript migration). All TypeScript ECMAScript conformance properties from that migration carry over directly.

Checklist

• PR body meets repo minimum length
• AGENTS.md / MIGRATED_LANGUAGES changelog updated inline (new entry in registry-primary-flag.ts)
• No secrets, tokens, or machine-specific paths committed
• Pre-commit hook passes (ESLint + Prettier + typecheck)
• 38 integration test cases (≥ 30 required by issue spec)
• SCOPE_RESOLVERS entry added
• MIGRATED_LANGUAGES entry added (triggers CI scope-parity gate automatically)

Risk & rollout

• Breaking changes: None. The flag defaults to true via MIGRATED_LANGUAGES, but operators can revert with REGISTRY_PRIMARY_VUE=0.
• Index refresh: npx gitnexus analyze after deploy to pick up new Vue CALLS/IMPORTS edges.
• Release notes: Vue SFC now uses registry-primary scope resolution. Expect improved cross-file method call resolution for Composition API composables and Options API components.

Tri-review: PR #1950 — Vue SFC → scope-based resolution (RFC #909 Ring 3, #940)

Verdict: not currently functional — do not merge yet. CI is red and the branch conflicts with main. The good news: the swarm + Codex converged on a small, concrete root cause with a clear fix.

Methods & engine breakdown (honest): 7 Compound-Engineering / GitNexus Claude lanes + Codex (the one genuinely independent engine, live). The 7 Claude lanes share a model family, so their agreement is correlated, not independent confirmation. The strong signal here is that Codex and the Claude correctness/adversarial lanes independently reached the same root cause, and CI reproduces it (run 26712104950).

P0 #1 — the new Vue provider emits ZERO IMPORTS and ZERO cross-file CALLS edges (inline on vue.ts)

vueProvider wires emitScopeCaptures but omits the four scope-resolution hooks the TypeScript provider supplies — interpretImport, interpretTypeBinding, bindingScopeFor, importOwningScope (typescript.ts:317–320). (The legacy importResolver/namedBindingExtractor on vue.ts:77–78 feed the old DAG path, not the registry-primary scope path.) pass3CollectImports early-returns when interpretImport is undefined (scope-extractor.ts:824), so parsedImports stays empty → no IMPORTS edges and therefore no cross-file CALLS edges. CI-reproduced: vue.test.ts 4 failures and the author's own vue-scope.test.ts 20/38 failures — every IMPORTS/CALLS assertion. Fix: add the four hooks (already exported) to vueProvider.

P0 #2 — flipping Vue into MIGRATED_LANGUAGES drops template-component CALLS for every Vue repo (inline on registry-primary-flag.ts)

isRegistryPrimary(Vue) becomes true, so call-processor.ts skips the legacy vue-template-component CALLS emitter — both emitters (≈L1499, ≈L3067) sit inside loops gated by if (isRegistryPrimary(language)) continue; (≈L835, ≈L2966). The parse worker still emits raw template calls (parse-worker.ts≈2091) but the gated loops discard them, and the new scope path explicitly excludes template expressions (captures.ts:11–13). Net: template component-reference CALLS edges vanish for all Vue repos, and this survives the #1 fix. The vue/index.ts limitation-#1 comment ("emitted by the legacy template extractor in the parse worker") is now stale/false and should be corrected. Fix: exempt the template emitter from the registry-primary skip, or don't flip Vue until the scope path covers template CALLS.

P1 #3 — worker-mode double extraction → zero captures on real repos (inline on captures.ts)

In worker mode (≥15 parseable files) the worker pre-extracts the <script> block and passes the already-extracted content as sourceText; emitVueScopeCaptures then runs extractVueScript a second time, gets null, and returns []. All four PR fixtures are 4–6 files, so they take the sequential path and never exercise this — a real Vue repo would get zero scope captures even after #1 is fixed. Confirmed by Codex (F3) + correctness + adversarial.

P1 #4 — cross-language .vue→.ts may not resolve (one lane; verify after #1)

The correctness lane reproduced (in isolation) that the per-language scope pass seeds allFilePaths only from the current language's files (run.ts≈296), so .ts targets can be absent during the Vue pass — meaning .vue→.ts IMPORTS/CALLS (e.g. App.vue→formatUser) may still be 0 after #1. Single-lane and partly masked by #1; re-check once the provider hooks land, and if it persists, thread the workspace-wide file set into the Vue resolver.

Process gap — the parity gate didn't catch this

scripts/run-parity.ts:44 derives the test file as test/integration/resolvers/${slug}.test.ts → only vue.test.ts. The new vue-scope.test.ts is never run by the scope-parity job (its 20 failures only surfaced in the full coverage suite). Register/rename it under the parity harness, and add a template-component CALLS assertion to the new fixtures (none exists today — the exact edge that regressed).

Credit / validated (not everything is broken)

• No O(n²) regression. The perf lane traced allFilePaths and confirmed it's a stable reference per pass, so the import-target.ts memoization rebuilds once per pass — the prior Python/Go migration hazard does not recur here. Codex independently refuted the cache-identity hypothesis.
• The vue/ module cleanly mirrors the established per-language layout; the shared-file edits add only routing-table entries (no language naming in shared logic). Symbol extraction from <script setup> works (those assertions pass).

Lower-priority (non-blocking, body-only)

• PassCache is now triplicated (TS/JS/Vue) — consider exporting a shared makeTsResolveImportTarget(language) factory (P2).
• vue/index.ts re-exports vueScopeResolver, which no consumer imports — the registry imports scope-resolver.ts directly (P3).
• A few new-suite assertions are weak: toBeGreaterThanOrEqual(1) where ≥2 imports are expected; a vacuous if (x !== undefined) guard at vue-scope.test.ts:243; symbol checks via flat toContain that don't bind the symbol to its .vue file.

CI / merge

CI Gate ✗ · scope-parity ✗ · coverage ✗ (24 failing assertions total) · typecheck/lint/format/build ✓. Merge state: CONFLICTING — rebase on main required.

[magyargergo]

Could we please benchmark it? We also need to attribute property usages of a component. Please make sure this is also tested and any of the callbacks on the component that call a function in the template.

[ReidenXerx]

Thanks for the thorough multi-lane review. All four actionable findings have been addressed in commit 3eb4fe9.

P0 #1 — Missing scope-resolution hooks in vueProvider

Added all four required hooks to vueProvider in vue.ts:

• interpretImport: interpretTsImport
• interpretTypeBinding: interpretTsTypeBinding
• bindingScopeFor: tsBindingScopeFor
• importOwningScope: tsImportOwningScope

Also completed the contract with receiverBinding, mergeBindings, arityCompatibility, and resolveImportTarget (matching what the TS and JS providers set).

P0 #2 — Template-component CALLS dropped when Vue is registry-primary

Added a dedicated post-loop pass in call-processor.ts (after the registry-primary-gated main loop) that emits reason: 'vue-template-component' CALLS edges for all Vue files whenever isRegistryPrimary(Vue) is true. The existing inline emitter at ≈L1506 is left in place for the non-migrated path; the new pass handles the migrated path without modifying the registry-primary skip guard.

Updated the stale limitation comment in vue/index.ts to correctly document the new emit site.

P1 #3 — Worker-mode double-extraction → zero captures

emitVueScopeCaptures is now idempotent. When extractVueScript returns null:

• If the content has SFC block-level markers (<template, <style) → genuine render-function-only component → return []
• Otherwise (no SFC markers) → already-extracted script content from worker pre-pass → delegate directly to emitTsScopeCaptures

Test assertion strictness

All toBeGreaterThanOrEqual(1) replaced with exact toBe(N) counts:

• CALLS — toBe(1) for each single call-site assertion
• IMPORTS — exact per-symbol counts based on scope-based emission (1 edge per value import, import type excluded): toBe(2) for UserProfile.vue → types.ts, toBe(3) for UserProfile.vue → api.ts, toBe(4) for TodoList.vue → utils.ts, toBe(1) for all single-symbol import assertions

Note on P1 #4 (cross-language .vue→.ts resolution): this is marked as single-lane and partly masked by P0 #1. With the provider hooks now in place, resolveTsImportTarget (which is resolveImportTarget in vueProvider) uses the workspace-wide file set via the allFilePaths parameter, not a per-language subset — so .ts targets should resolve. If CI still shows failures there after P0 #1 lands, we can thread the workspace file set explicitly as suggested.

Note on the parity-gate process gap: vue-scope.test.ts needs to be registered in the scope-parity harness. Happy to add it as a follow-up if that's preferred, or to amend this commit.

[ReidenXerx]

Addressed the benchmark + template-attribution request in commit dbafec1.

Template event-handler CALLS

Added extractTemplateEventHandlers to vue-sfc-extractor.ts. Extracts bare single-identifier handler names from @event="methodName" / v-on:event="methodName" attributes. Inline expressions with arguments (@click="toggle(item)") are intentionally excluded — they cannot be resolved to a single call target without a full template AST (tracked in #1647).

The dedicated Vue template pass in call-processor.ts now calls ctx.resolve(handlerName, file.path) and emits a CALLS edge with reason: 'vue-template-callback' for each matched Function/Method node.

New tests (all toBe(1)):

• @click="handleSave" → CALLS handleSave (UserProfile.vue)
• @select="onPostSelected" → CALLS onPostSelected (App.vue composition)
• @keyup.enter="addTodo" → CALLS addTodo (TodoList.vue)
• @loaded="onUserLoaded" → CALLS onUserLoaded (App.vue cross-file)

Template attribute-binding ACCESSES

Added extractTemplateAttributeBindings to vue-sfc-extractor.ts. Extracts plain identifiers from :prop="varName" / v-bind:prop="varName" bindings. Member-access expressions (:key="post.id") and literals are safely excluded by the identifier-boundary regex.

Emits ACCESSES edges with reason: 'vue-template-attribute' for each resolved binding target.

New tests (all toBe(1)):

• :userId="currentUserId" → ACCESSES currentUserId (App.vue)
• :posts="allPosts" → ACCESSES allPosts (App.vue)

Benchmark

Added test/integration/vue-pipeline-benchmark.test.ts (gated by GITNEXUS_BENCH=1). Generates synthetic repos at 10 / 25 / 50 / 100 components and asserts:

• Wall-clock scaling ratio < 4× per component-count doubling
• Node-count growth ratio < 1.5× (guards against accidental O(n²) cross-component import fan-out)

Run with: GITNEXUS_BENCH=1 npx vitest run test/integration/vue-pipeline-benchmark.test.ts

Note on complex inline template expressions ({{ formatDate(x) }}, @click="() => count++"): these require full template AST parsing and are documented in vue/index.ts limitation #1, tracked in #1647.

I afraid treat this situation
-> of emitting callback from A in B component
as CALLS could make much noise because imagine multilevel chain of emitting during event dispatching in big components hierarchies
It could produce huge amount almost meaningless edges because emitting of stuff could mean nothing from the sense-full perspective of callstack graph hierarchy we chase

Component-event edge model revision

Following the discussion about avoiding CALLS noise in deep component hierarchies, I've revised the template-derived edge model.

The problem with CALLS for component events

Using ComponentB CALLS ComponentA.handleAction as a direct edge is semantically incorrect and creates noise in large hierarchies — a component emitting an event doesn't call the parent's handler; the framework dispatches it. This can produce O(hierarchy depth) misleading CALLS edges that pollute impact analysis.

New model

The implementation now uses dedicated edge types that accurately model the Vue event system and remain joinable via Cypher for impact tracing without polluting the CALLS graph:

Pattern	Edge type	Source → Target	Reason
<ComponentB @action="handleAction" />	BINDS_EVENT_HANDLER	handleAction fn → ComponentB.vue File	vue-event: @action
emit('action', payload) in ComponentB	EMITS_EVENT	ComponentB.vue File → self	vue-emit: action
<button @click="doThing">	CALLS	File → doThing fn	vue-template-callback
<ComponentB :prop="val" />	ACCESSES	File → val variable	vue-template-attribute

Cypher impact query — "what handlers could receive ComponentB's 'action' event?":

MATCH (child:File)-[:EMITS_EVENT {reason: 'vue-emit: action'}]->(child)
MATCH (handler)-[:BINDS_EVENT_HANDLER {reason: 'vue-event: @action'}]->(child)
RETURN handler

What changed

• gitnexus-shared: added BINDS_EVENT_HANDLER and EMITS_EVENT to RelationshipType
• vue-sfc-extractor: added extractComponentEventBindings, extractNativeElementEventHandlers, extractScriptEmitCalls
• ScopeResolver contract: new optional emitPostResolutionEdges hook (language-agnostic, runs after all standard passes)
• vue/scope-resolver: implements the hook — native DOM event handlers still use CALLS, cross-component bindings use BINDS_EVENT_HANDLER
• call-processor.ts: reverted the dedicated Vue post-loop pass (per review feedback that this file will be removed)

[magyargergo]

Tri-review (delta): PR #1950 — Vue SFC → scope-based resolution (RFC #909 Ring 3, #940)

Verdict: not production-ready. The PR's own integration suite is RED on the default (registry-primary) path — 21 of 46 vue-scope.test.ts assertions fail, which I reproduced locally and which the live tests / ubuntu / coverage job also fails. The migration's headline capability — cross-file .vue → .ts resolution — emits zero edges on the registry-primary path, a regression vs the legacy path it replaces. Credit where due: two prior-review findings were genuinely fixed (provider hooks; template-CALLS double-count). But prior P1#4 (.vue→.ts) and the parity-gate process gap were not.

Methods & engine breakdown (honest). Codex (the one genuinely independent engine — live, completed) + 7 Claude lanes (risk, test/CI, correctness, adversarial, performance, maintainability, testing). The 7 Claude lanes share a model family, so their agreement is correlated, not independent confirmation. The strong signals below are where Codex and the Claude lanes independently converged AND I reproduced the failure.

Review bar (DoD). RFC #909 Ring 3 + the scope-parity policy: (1) scope-parity green for Vue under both flags; (2) the new integration suite green on the default path; (3) no regression vs the legacy resolver; (4) template/event edges correct. Items 1–3 are not met.

What I verified. Reproduced npx vitest run test/integration/resolvers/vue-scope.test.ts → 21 failed / 25 passed (46) on default; REGISTRY_PRIMARY_VUE=0 (legacy) → 2 failed / 31 passed / 13 skipped (so the legacy path resolves what registry-primary drops). All six inline anchors confirmed as added/RIGHT diff lines on head 91ddbee8. Reviewed head was e290f5a; 91ddbee8 differs only by a merge-from-main CI file (ci-devcontainer.yml) — Vue code is identical (Codex independently spot-checked head identity).

Fixed since the last review (credit)

• P0#1 fixed — vueProvider now wires all scope hooks (interpretImport/interpretTypeBinding/bindingScopeFor/importOwningScope + emitScopeCaptures/resolveImportTarget/…).
• P0#2 handled, no double-count — the legacy vue-template-component CALLS emitters in call-processor.ts are gated off for registry-primary languages, so emitPostResolutionEdges is the sole emitter. .vue→.vue template edges (component CALLS, native callbacks, ACCESSES, EMITS_EVENT) all pass.
• No O(n²) memoization regression — the allFilePaths-reference memoization in import-target.ts rebuilds once per pass (stable reference, single call site); the prior migration hazard does not recur.

P0 — .vue → .ts imports & cross-file CALLS resolve to ZERO (inline on registry-primary-flag.ts)

• Risk: every real Vue repo (components import composables/api/models/types from .ts) loses all .vue→.ts IMPORTS and the CALLS that depend on them, in the graph powering MCP queries / wiki / process traces. A regression vs today's legacy default.
• Evidence: the per-language scope pass feeds the resolver only .vue files (phase.ts:183), so allFilePaths (run.ts:346) holds only .vue paths; resolveTsTarget('./api', {only .vue}) → null. 18 of the 21 default-path failures; live tests / ubuntu / coverage red; legacy passes these. Reproduced (Codex + risk + correctness + adversarial + test/CI + my run).
• Fix: give the Vue pass a cross-language file universe and the TS ParsedFile scope models (Codex: widening allFilePaths alone restores IMPORTS but not the imported-symbol CALLS — finalize-orchestrator.ts:110-115).
• Blocks merge: YES.

P1 — the scope-parity gate never runs the new suite (inline on helpers.ts)

• Risk: the migration's safety gate is inert — none of the new scope/template/event behavior is parity-checked.
• Evidence: scripts/run-parity.ts:44 maps slug vue → vue.test.ts (pre-existing, lenient), never vue-scope.test.ts, so the 13 new LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES['vue'] entries are dead config under either flag. Verified npx tsx scripts/run-parity.ts --language vue loads vue.test.ts (Codex + test/CI + testing). (The test/CI lane reports even vue.test.ts fails 2 assertions on its registry-primary leg, so the pending scope-parity job may itself go red.)
• Fix: discover ${slug}*.test.ts in the parity runner (or rename/merge the suite); add a meta-test that every MIGRATED_LANGUAGES slug has a parity-run suite.
• Blocks merge: YES (the gate guarding this migration is disabled).

P2 findings (inline)

• BINDS_EVENT_HANDLER tests assert the wrong endpoint (vue-scope.test.ts:173,458) — they check e.target === 'onPostSelected', but the edge is source=handler, target=childFile (matches scope-resolver.ts:202-203 and the types.ts contract). The edge is emitted correctly; the test can't pass → contributes to red CI. Fix: assert e.source. Codex + risk + correctness + adversarial + testing + reproduced. Blocks merge: YES.
• Worker-mode capture drop (captures.ts:58) — in worker mode (≥15 files) the bare-script hasSfcMarkers substring test misreads a <script> containing the substring <template/<style (comment/string) as a no-script SFC → all scope captures dropped for that file. Codex + correctness (reproduced via the pure fn). Blocks merge: MAYBE (latent; no worker-mode test exists).
• EMIT_CALL_RE over-matches (vue-sfc-extractor.ts:166) — \bemit( matches socket.emit('x'), $emit, and emit('x') in comments/strings → spurious EMITS_EVENT self-edges. Codex + correctness + adversarial (reproduced). Blocks merge: NO.
• kebab-case components misclassified (vue-sfc-extractor.ts:152-153) — <post-list @select="h"> (spec-equivalent to <PostList>) is treated as a native element → native-callback CALLS instead of component CALLS + BINDS_EVENT_HANDLER. Codex + correctness + adversarial (reproduced). Blocks merge: NO.

Lower-priority (body-only)

• More regex-fidelity gaps (reproduced, Codex + adversarial): HTML-commented template tags emit phantom CALLS/BINDS/ACCESSES (comments not stripped); namespaced <Foo.Bar> truncated to Foo; a literal > inside an attribute value drops the rest of the tag (affects native handlers too — only the component case is documented under #1647).
• emitPostResolutionEdges O(V²) (scope-resolver.ts:148, perf lane, single-lane code-read) — rebuilds importTargetByName per .vue file by scanning the workspace-wide indexes.imports with no break. ~1–2 s at ~8 k files (theoretical, code-read estimate — not benchmarked); negligible at app scale. Build a filePath→imports map once.
• methods block test red in both modes (risk + correctness + test/CI + testing) — Options-API methods are emitted as Method nodes, but extracts Function nodes from methods block queries the Function label → fails in both modes and isn't in the expected-failures list.
• EMITS_EVENT doc/code mismatch (correctness + maintainability, code-read) — gitnexus-shared/types.ts says source = enclosing Function/Method (File fallback), but the code always emits File→File.
• Maintainability (code-read): PassCache/resolver triplicated (TS/JS/Vue) → extract a shared factory; dead exported extractTemplateEventHandlers+EVENT_HANDLER_RE (no consumers); vue/index.ts barrel unused (consumers import modules directly); the captures.ts header comment about the "legacy template extractor … double-counted" is now inverted (legacy is gated off for registry-primary) and should be corrected; emitPostResolutionEdges JSDoc says "four categories" but emits five (inline numbering skips #3).

Test gaps (beyond the parity wiring)

Weak/non-binding assertions (toContain(name) not bound to a file; CALLS matched by target name only); a vacuous if (addTodo !== undefined) guard (vue-scope.test.ts:308) green for the wrong reason while addTodo isn't extracted; zero negative assertions for the documented exclusions (inline-expression handlers, member-access bindings, type-only imports); no test asserts edges survive worker mode (≥15 files) — the only ≥15-file path is the GITNEXUS_BENCH-gated benchmark, which records edgeCount but asserts only node/time ratios.

Refuted (validation is a feature)

ReDoS on the new regexes (all linear, ≤10 ms on multi-MB inputs); edge-id collisions (idempotent/correct); the emitPostResolutionEdges guard harming other languages (correctly !== undefined; others leave it unset); new RelationshipType values breaking an exhaustive switch (none over RelationshipType; web UI has a fallback); template edges vanishing in worker mode (they read full SFC fresh from disk — only the captures path has the drop above); and the allFilePaths-reference memoization O(n²) hazard.

CI / merge

• Merge state: checks failing — tests / ubuntu / coverage FAILED (the coverage/full-suite job, where vue-scope.test.ts's 21 failures land); scope-parity / scope-resolution parity was pending at review time (and may go red on vue.test.ts's registry-primary leg). All other gates (typecheck/lint/format/build/platform test shards/benchmarks/CodeQL/gitleaks) pass. Vercel ✗ is an unrelated fork deploy-authorization failure, not a code issue.
• Branch hygiene: merge-from-main commit present but harmless and merge-safe — the branch is BEHIND main as of 91ddbee8; the only delta vs the reviewed e290f5a is a ci-devcontainer.yml main-merge (Vue code identical, Codex-confirmed). Further main divergence beyond that commit is unverified.

Final verdict

not production-ready. It ships with its own integration suite red on the default path (21/46, reproduced locally and on tests / ubuntu / coverage), and its headline cross-file .vue→.ts resolution emits zero edges where the legacy path it replaces resolves them — a user-visible regression for essentially every real Vue repo. The migration's parity gate doesn't run the new suite, so that behavior is unguarded. The provider-hook fix and the no-double-count template path are real progress, and the lightweight regex/event design is reasonable, but the cross-language resolution gap (needs the TS scope models in the Vue finalize universe, not just a wider allFilePaths) plus two test-authoring bugs must be resolved before merge.

[P1 · process · reproduced] These 13 vue: expected-failures are keyed to vue-scope.test.ts test names, but the scope-parity job never runs that file: scripts/run-parity.ts:44 maps slug vue → test/integration/resolvers/${slug}.test.ts = vue.test.ts (pre-existing, lenient). So this block is dead config and the migration's new scope/template/event behavior is unguarded by the parity gate — the prior review's process gap, unchanged. Verified: npx tsx scripts/run-parity.ts --language vue loads vue.test.ts.

Fix: have the parity runner discover ${slug}*.test.ts (or rename/merge the suite into vue.test.ts); consider a meta-test asserting every MIGRATED_LANGUAGES slug has a parity-run suite.

[ReidenXerx]

Addressed the new review points and pushed in commit 40b4bbed.

Fixed:

• P0 Vue scope context: Vue registry-primary now includes reachable TS/JS import-closure files for resolution context.
• BINDS_EVENT_HANDLER assertions: corrected source/target endpoint checks in vue-scope.test.ts.
• Parity process gap: scripts/run-parity.ts now runs ${slug}*.test.ts, so Vue parity includes both vue.test.ts and vue-scope.test.ts.
• Worker-mode SFC/script ambiguity: replaced marker sniffing with explicit source-kind metadata from worker (full-file vs pre-extracted-script).
• emit() false positives: replaced regex-only extraction with a lightweight lexer-state scanner (ignores comments/strings/property emits).
• kebab-case component tags: handled as component candidates (with Vue built-in kebab tags excluded).

Validation:

• npx tsc --noEmit
• npx vitest run test/unit/vue-sfc-extractor.test.ts
• npx vitest run test/integration/resolvers/vue-scope.test.ts
• npx tsx scripts/run-parity.ts --language vue

What looks good

The main concern from earlier reviews around duplicate vue-template-component CALLS edges does not appear to be an issue. The legacy emitters are skipped once Vue runs as registry-primary, and the new resolver uses the same edge id scheme, so graph.addRelationship dedupes correctly.

The EMITS_EVENT File → File edges also look downstream-safe. The consumers I checked either skip self-referential edges or use a visited/seen set during traversal, so this does not look like a runtime breakage. It is more of a contract/docs mismatch.

The arity-adapter argument order also looks correct after review, and the import-alias mapping does not appear to mis-target edges.

The Vue tests are meaningful rather than just presence-based. The Vue SFC extractor tests, Vue scope registry-primary tests, and the legacy parity leg all pass, with expected skips registered where appropriate.

Main issues I would address

1. Potential quadratic regex / ReDoS-style blowup in Vue template scanning

The new template tag regexes in vue-sfc-extractor.ts share the shape:

<name([^>]*?)(?:\/>|>)

Because these run globally, a large .vue template with many unclosed tag starts can cause repeated rescanning of the tail of the file. One adversarial lane reproduced ~18s of single-threaded time on a ~480KB file, which is still under the current walker cap.

This is not necessarily a common real-world Vue file, and a similar pattern already exists elsewhere, so I would not frame this as a brand-new class of risk. However, this PR adds more of these patterns and runs them on the main thread during post-resolution edge emission.

Suggested fix: bound the attribute span, for example with something like [^>]{0,512}?, or tokenize the template once and reuse that result.

---

2. Kebab-case components can be misclassified as native tags

NATIVE_TAG_RE currently matches lowercase prefixes of kebab-case component tags.

For example:

<my-widget @foo="onFoo" />
<post-list @select="onSelect" />

These can be treated as native elements, which may emit spurious native vue-template-callback CALLS edges. Kebab-case components are standard Vue usage, so this should probably have explicit fixture coverage.

Suggested fix: ensure native tag extraction excludes kebab-case component tags and known component/builtin patterns before emitting native callback edges.

---

3. Kebab-case event names are currently dropped

TAG_EVENT_RE uses an event-name character class that excludes -, so events like these are missed:

<UserCard @user-loaded="onUserLoaded" />
<MyInput @update:model-value="onModelValue" />

That means no BINDS_EVENT_HANDLER edge is emitted for normal Vue event names containing hyphens.

Suggested fix: widen the event-name regex to include -, and add fixtures for @user-loaded and @update:model-value.

---

4. Options API $emit coverage is incomplete

The current emit lexer appears to reject this.$emit(...), and the event-name validator rejects names containing :, such as update:modelValue / update:model-value.

That means EMITS_EVENT coverage currently works mainly for Composition API emit(...), while common Options API patterns are silently uncovered.

This may be intentional for this PR, but if so, I think it should be documented clearly. Otherwise, we should add support and tests for:

this.$emit('save')
this.$emit('update:modelValue')
this.$emit('update:model-value')

---

5. TS/JS context collection may do extra work and can truncate context

collectVueScopeFilePaths pulls imported TS/JS files into the Vue run. Cleanup only removes the primary .vue paths, so there are two possible effects:

1. TS/JS files may be processed redundantly by both the Vue run and the normal TS/JS run.
2. In sequential mode, context can dead-end because .vue content is available, but imported TS/JS content may not be available in entryFileContents / preExtractedByPath.

The currently passing fixture proves the depth-1 case works, so this is not a confirmed correctness bug yet. Still, the ownership model is unclear: either Vue should only collect the context it truly needs, or the shared pipeline should expose a cleaner provider hook for language-specific scope context.

---

Maintainability / cleanup items

A few non-blocking items would be good to clean up while this code is still fresh:

• phase.ts now hardcodes Vue-specific logic in shared ingestion code. This appears to violate the existing direction that shared pipeline code should not name individual languages. A provider hook would keep the Vue policy inside languages/vue.
• extractTemplateEventHandlers appears to be exported but unused.
• EVENT_HANDLER_RE seems to duplicate TAG_EVENT_RE.
• The docs say there are 4 edge categories, but the implementation emits 5.
• The numbered comments skip from 1, 2 to 4, 5, 6.
• types.ts describes EMITS_EVENT source as Function/Method, but the implementation emits File → File.
• .vue files appear to be read more than once.
• emitPostResolutionEdges does several full-content regex scans per .vue file.

[ReidenXerx]

Addressed all items from the Jun 2 review. Two commits pushed:

---

Commit 1 — 81abe5d · Correctness + architecture

ReDoS mitigation
Bounded [^>]*? attribute spans in COMPONENT_TAG_RE, KEBAB_COMPONENT_TAG_RE, and NATIVE_TAG_RE to [^>]{0,512}?.

Kebab-case misclassified as native
Added (?![A-Za-z0-9-]) negative lookahead to NATIVE_TAG_RE. <post-list @select=\"h\"> no longer splits as native tag post with attrs -list @select=\"h\".

Hyphenated event names dropped
TAG_EVENT_RE widened from [\w:.]+ → [\w:.-]+ so @user-loaded and @update:model-value emit correct BINDS_EVENT_HANDLER edges.

Options API this.$emit silently dropped
collectBareEmitEventNames now allows this.$emit(...) by looking back past the . to verify the preceding token is exactly this. All other property-access forms (socket.emit, bus.emit) remain blocked.

Event names with : rejected
Validator extended from ^[A-Za-z][A-Za-z0-9-]*$ to ^[A-Za-z$_][A-Za-z0-9:_$-]*$ — covers update:modelValue and update:model-value.

Vue-specific logic removed from shared phase.ts
collectVueScopeFilePaths / VUE_SCOPE_CONTEXT_LANGUAGES moved out of phase.ts into a new collectScopeContextPaths optional hook on ScopeResolver. vueScopeResolver implements it; phase.ts is fully language-agnostic.

Memory leak closed
preExtractedByPath cleanup now iterates filePaths (all context files) so TS/JS context files are evicted after the Vue pass, not just the primary .vue files.

Cleanup

• Removed unused extractTemplateEventHandlers and duplicate EVENT_HANDLER_RE.
• Fixed skipped comment numbers in emitPostResolutionEdges (1, 2, 4, 5, 6 → 1–6).
• vue/index.ts doc: four edge categories → five (added EMITS_EVENT).
• gitnexus-shared EMITS_EVENT JSDoc corrected to reflect File→File source/target.

Tests
7 new unit tests: @user-loaded, @update:model-value, kebab-case not misclassified as native, this.$emit('save'), this.$emit('update:modelValue'), socket.emit still rejected, colon event names accepted.

---

Commit 2 — 1198d4f · Performance

No more double read of .vue files in phase.ts
Primary files were read once for the collectScopeContextPaths hook and again in the blanket readFileContents(filePaths) call. Now the primary-file map is reused and only the extra TS/JS context files require a second I/O round-trip.

Single template parse per .vue file in emitPostResolutionEdges
Previously each of the five extractors (components, native handlers, component events, emit calls, attribute bindings) ran TEMPLATE_RE.exec(content) independently — five full-file regex scans per .vue. Replaced with a new extractVueTemplateEdgeData batching function that parses template and script once and feeds all five extractors from pre-extracted content.

---

All 12 inline review comments and all 5 main issues from the Jun 2 summary are addressed. 72 tests pass (26 unit + 46 integration, all with exact toBe counts).

I think some tests need to be excluded from the legacy resolution. 🤔 Take a look at gitnexus/test/integration/resolvers/helpers.ts

[ReidenXerx]

Fixed: TypeScript parity gate failures

The scope-parity / scope-resolution parity CI was failing with 3 typescript [legacy] failures. Root cause: the parity runner's ${slug}-*.test.ts glob (introduced to pick up vue-scope.test.ts) also caught three TypeScript test files that exercise scope-resolver-only correctness wins:

• typescript-hoc-wrapped.test.ts — HOC-wrapped const declarations (forwardRef, memo, useCallback, useMemo, observer, debounce)
• typescript-hof-callbacks.test.ts — HOF-callback caller attribution (Promise fan-out, queryFn pair-arrows, Zustand actions)
• typescript-jsx-as-call.test.ts — JSX-as-call CALLS edges (<Foo /> → Foo)

All three were using plain it() from vitest, so legacy-failing tests were reported as failures instead of being skipped.

Fix applied (commit 4a756659):

• Converted all three files to use createResolverParityIt('typescript') (same pattern as vue-scope.test.ts)
• Added 26 legacy-failing test names to LEGACY_RESOLVER_PARITY_EXPECTED_FAILURES.typescript with explanatory comments documenting why each is a scope-resolver-only correctness win

Result:

• Legacy mode: 11 + 11 + 4 tests skipped (↓), zero failures
• Registry-primary mode: all 18 + 12 + 7 = 37 tests pass as before

[magyargergo]

@ReidenXerx We need to remove test/unit/registry-primary-flag.test.ts file because we finshed the migration. 🥳
