Why this is useful

Many production codebases use async job queues (BullMQ, Temporal, etc.) to decouple producers from consumers. Without this PR, GitNexus has a blind spot: a file that enqueues a job and the worker that processes it appear completely unrelated in the graph — no edges connect them, and execution flow detection can't trace the async handoff.

With ENQUEUES/PROCESSES edges, GitNexus can now:

1. Impact analysis — changing a queue producer surfaces the downstream workers that will be affected, and vice versa
2. Execution flow detection — async pipelines (e.g., upload → transcode → notify) become visible as connected process graphs instead of isolated islands
3. Codebase exploration — querying "what processes the video-processing queue?" returns the worker file directly, rather than requiring manual grep

This closes a gap similar to what HANDLES_ROUTE/FETCHES did for HTTP request flows — but for async/event-driven architectures.

[marxo126]

Rebased onto main

Force-pushed — removed an accidental SwiftUI navigation commit (5026870) that was in the branch history because the queue detection branch was created from the SwiftUI branch instead of main. This happened due to concurrent Claude Code sessions sharing the same working directory and switching branches on each other.

The queue detection code is unchanged (2 commits), only the SwiftUI contamination was removed.

Final Production Readiness Review

Tasks

• Gather context and understand the PR
• Read all changed files
• Review schema and type changes
• Review core ingestion logic (parse-worker, call-processor, parsing-processor, pipeline)
• Review framework detection changes
• Review tests and fixtures
• Assess production readiness and summarize

---

Verdict: Not yet ready to merge — 2 significant issues found

CI passes and the feature works for the happy path (BullMQ producer/consumer), but there are two meaningful issues that could result in misleading graph data in production: a DRY violation with a silent split brain risk, and a Temporal semantic mismatch.

---

Issues

🔴 Issue 1: Duplicated extraction logic (maintenance split-brain risk)

The extractQueuePatterns() function in parse-worker.ts was inlined verbatim into pipeline.ts to avoid a worker-thread import problem. This creates two canonical copies of the same regex logic:

• parse-worker.ts:361-369 — used by the worker path
• pipeline.ts:804-820 — used by the sequential fallback path

The regexes are identical right now, but they will inevitably diverge when someone fixes a bug or adds a new pattern to one without updating the other. This is particularly fragile because:

1. The divergence won't cause a test failure — it will just silently produce different results depending on whether workers are available
2. The sequential fallback is common in CI/low-concurrency environments

The root cause (can't import extractQueuePatterns from parse-worker.ts into pipeline.ts) should be fixed by moving the function to a shared utility module (e.g., utils/queue-patterns.ts) that neither file depends on for worker-thread reasons.

Fix this →

---

🟠 Issue 2: Temporal modeling is semantically incorrect

The Temporal detection creates CodeElement nodes whose name/queueName is the activity method name (e.g., validateOrder, chargePayment), not the Temporal task queue name (e.g., 'orders'). This produces a fundamentally misleading graph.

What the code does — for workflow.ts:

const activities = proxyActivities({ startToCloseTimeout: '30s' });
await activities.validateOrder(orderId);   // → CodeElement node named "validateOrder"
await activities.chargePayment(amount);    // → CodeElement node named "chargePayment"

Result: workflow.ts gets PROCESSES edges to nodes named validateOrder, chargePayment, sendConfirmation — three separate "queue" nodes that don't correspond to any real queue.

What it should be — The actual task queue is 'orders', defined in starter.ts:

client.workflow.start(processOrderWorkflow, { taskQueue: 'orders', ... });

The workflow.ts file calls activities (producer role), while workers registered on the 'orders' task queue are the consumers. The current model:

1. Assigns PROCESSES edges to the workflow file (it's actually more of a producer/orchestrator)
2. Creates nodes named after function calls, not queues
3. Conflates activity method names with queue names

Additionally, TEMPORAL_ACTIVITY_RE = /activities\.(\w+)\s*\(/g will match any object named activities in any codebase — a common variable name — producing false positives in non-Temporal projects.

Fix this →

---

Minor notes (non-blocking)

BullMQ false-positive trigger: content.includes('new Worker') fires for any Web Worker or Node.js worker_threads usage. The downstream regex is narrow enough that it won't create false edges, but it wastes CPU on the hot path for every file containing new Worker.

Missing framework-detection.ts changes: The PR description mentions "Add framework detection patterns for BullMQ and Temporal in path-based and AST-based detection" but the framework-detection.ts file has zero changes. Either the description is stale or those changes were dropped.

Weak test assertions: toBeGreaterThanOrEqual(1) verifies the feature works but not that it works correctly. A more meaningful test would assert specific queue names and file links:

// e.g.
const enqueues = result.graph.relationships.filter(r => r.type === 'ENQUEUES');
const queueNode = result.graph.nodes.find(n => n.properties.name === 'video-processing');
expect(queueNode).toBeDefined();
expect(enqueues.some(e => e.targetId === queueNode!.id)).toBe(true);

Line number computation is O(n) per match: content.substring(0, m.index).split('\n').length - 1 runs for every match. For large files with many queue calls this is wasteful. A simple counter scanning for \n characters would be O(n) total instead of O(n) per match.

Coverage drop: All metrics declined ~0.4%. The new code for the sequential fallback path in pipeline.ts is tested indirectly, but the inline block is not explicitly unit-tested.

---

What's working well

• BullMQ producer/consumer detection is correct — queue variable name is tracked and resolved before creating edges
• processQueuePatterns deduplicates queue nodes correctly (checks graph.getNode(qid) before creating)
• Edge IDs include lineNumber to avoid collision when a file enqueues/processes the same queue multiple times
• The ENQUEUES/PROCESSES distinction is semantically sound for BullMQ
• Schema changes (REL_TYPES, RelationshipType) are complete and consistent
• CI passes with all 4199 tests green

[marxo126]

Review findings addressed (efe2fcf)

1. Deduplicated extraction logic

Moved extractQueuePatterns() to a shared utility module at gitnexus/src/core/ingestion/utils/queue-extraction.ts. Both parse-worker.ts (worker threads) and pipeline.ts (sequential fallback) now import from this single source.

2. Fixed Temporal semantic modeling

• taskQueue extraction: client.workflow.start(fn, { taskQueue: 'orders' }) now extracts the actual taskQueue name ('orders') instead of using the workflow function name
• Activity calls create ENQUEUES: activities.methodName() calls now produce ENQUEUES edges (producer role) instead of PROCESSES edges — they dispatch work to a task queue, not consume it
• proxyActivities guard: The activities.foo() regex now only fires when the file contains proxyActivities, avoiding false positives on non-Temporal code that happens to have an object named activities
• Simplified role union: ExtractedQueuePattern.role narrowed from 'producer' | 'consumer' | 'workflow' | 'activity' to 'producer' | 'consumer'

Tests

• 5 integration tests added covering ENQUEUES/PROCESSES edges, CodeElement queue nodes, taskQueue name extraction, and proxyActivities guard behavior
• All 3870 existing tests pass, no regressions

[marxo126]

Rebased onto latest upstream/main — merge conflicts resolved. Typecheck passes, queue-detection tests pass (5/5). Pre-existing test failures in express-routes, python-mcp-tools, and skip-git-cli are unrelated.

Final Production Readiness Review

Tasks

• Gather context and understand the PR
• Read all changed files
• Verify Issue 1 fix: deduplicated extraction logic
• Verify Issue 2 fix: Temporal semantic modeling
• Review integration tests and fixtures
• Check for any remaining issues
• Provide final verdict

---

Verdict: Conditional merge — BullMQ is production-ready; one residual Temporal concern

The two blocking issues from the previous review were addressed. CI is green, no regressions. The BullMQ feature is solid. One Temporal semantic issue persists — not a regression, but worth understanding before merging.

---

Previous Issues — Status

✅ Issue 1: Deduplicated extraction logic — Fully fixed

extractQueuePatterns now lives in utils/queue-extraction.ts and is imported by both paths:

• parse-worker.ts:59 — import { extractQueuePatterns } from '../utils/queue-extraction.js'
• pipeline.ts:19 — import { extractQueuePatterns } from './utils/queue-extraction.js'

The comment on the old location (parse-worker.ts:364) correctly directs readers to the shared module. No duplication remains.

⚠️ Issue 2: Temporal semantic modeling — Partially fixed

Three of the four concerns from the original review are resolved:

Concern	Status
proxyActivities guard to avoid false positives on activities.foo()	✅ Fixed — TEMPORAL_PROXY_ACTIVITIES_RE guards the activity path
workflow.start uses workflow function name as queue name	✅ Fixed — 500-char lookahead extracts taskQueue: 'orders' from the options object
Activity calls produce PROCESSES edges (consumer role)	✅ Fixed — role: 'producer' → ENQUEUES edges

Remaining concern: Activity method names are still used as queueName (queue-extraction.ts:148):

// activities.validateOrder(...) → queueName: 'validateOrder'
out.push({
  role: 'producer',
  queueName: m[1],    // ← activity method name, not a real task queue
  handlerName: m[1],
  ...
});

On the fixture workflow.ts, this produces three CodeElement nodes named validateOrder, chargePayment, sendConfirmation with description "Queue: validateOrder" etc. — none of which correspond to real Temporal task queues. The actual task queue ('orders') is correctly extracted from starter.ts → workflow.start, but the workflow file's activity calls still create spurious queue nodes.

This is semantic noise, not a correctness regression for BullMQ. But for codebases with Temporal workflows it will inflate the queue node count with activity method names.

Fix this →

---

Remaining Minor Notes (non-blocking, carried from previous review)

new Worker false-positive trigger (queue-extraction.ts:69): content.includes('new Worker') fires for worker_threads / Web Worker usage. The downstream regex (BULLMQ_WORKER_RE) is narrow enough to not create false edges — the cost is a wasted regex scan per file. Low impact.

framework-detection.ts unchanged: PR description says "Add framework detection patterns for BullMQ and Temporal in path-based and AST-based detection" but the file has zero diffs. Either the description is stale or those changes were intentionally dropped. Worth clarifying but not blocking.

Weak test assertions: Tests still use toBeGreaterThanOrEqual(1). The proxyActivities guard test (queue-detection.test.ts:49) checks reasons.some(r => r.includes('producer')), which would pass on BullMQ edges alone — it doesn't specifically verify the Temporal guard behavior.

Temporal taskQueue lookahead is fragile: The 500-char lookahead for taskQueue: (queue-extraction.ts:124) will silently fall back to the workflow function name for unusually long option objects. Acceptable for most real-world code, but worth a comment.

---

What's Working Well

• BullMQ detection is complete and correct — variable tracking (Queue('name') → q.add()) resolves the right queue name before creating edges
• Deduplication in processQueuePatterns — graph.getNode(qid) prevents duplicate queue nodes across chunks (call-processor.ts:1636)
• Edge ID includes lineNumber — prevents collision when a file enqueues the same queue multiple times (call-processor.ts:1639)
• Schema changes are consistent — REL_TYPES, RelationshipType, and all processor imports are aligned
• Shared utility is clean — queue-extraction.ts has a single export, good inline comments, and the O(n) lineAt fix from the previous review is in place

---

Summary

The PR is ready to merge with the understanding that Temporal activity-method nodes are semantic noise, not incorrect BullMQ behavior. If Temporal support is a day-1 requirement, the activity queueName field should be revisited before merging. If BullMQ is the primary use case, this can be merged and the Temporal refinement tracked as a follow-up.

[marxo126]

Rebased onto latest upstream/main

Resolved merge conflicts (additive merge — kept both sides):

• parse-worker.ts: Import conflict — added both FieldInfo/CLASS_CONTAINER_TYPES imports (from Phase 8/9) and extractQueuePatterns import (from this PR)
• pipeline.ts (auto-merged by git): Destructuring of runChunkedParseAndResolve return value and ORM block closure were correctly resolved

Verification:

• Typecheck: clean (tsc --noEmit — zero errors)
• Tests: 4444 passed, 11 skipped. 2 pre-existing failures (express-routes, python-mcp-tools) — unrelated to this PR, same as previous rebase

Final Production Readiness Review

Tasks

• Gather context and understand the PR
• Read all changed files in current state
• Verify previous fixes are intact after rebase
• Check for any new issues introduced by rebase
• Assess residual Temporal concern
• Provide final verdict

---

Verdict: Merge with one caveat — Temporal activity nodes are still semantic noise

The rebase is clean. All previous fixes are intact. BullMQ detection is production-ready. The single residual Temporal concern from the last review is still present and unchanged.

---

Fix Verification

✅ Issue 1: Deduplication — Confirmed fixed

Both paths import from the shared module:

• parse-worker.ts:60 → import { extractQueuePatterns } from '../utils/queue-extraction.js'
• pipeline.ts:20 → import { extractQueuePatterns } from './utils/queue-extraction.js'

No duplication. Single source of truth at utils/queue-extraction.ts.

✅ Issue 2 (partial): Temporal semantic modeling — 3 of 4 concerns fixed

Concern	Status
proxyActivities guard on activities.foo()	✅ queue-extraction.ts:141
taskQueue: 'orders' extracted from client.workflow.start	✅ queue-extraction.ts:119-135
Activity calls produce ENQUEUES (not PROCESSES)	✅ queue-extraction.ts:146
Activity method names used as queueName	⚠️ Still present — queue-extraction.ts:147

✅ Rebase is clean

parse-worker.ts correctly imports both FieldInfo/CLASS_CONTAINER_TYPES (Phase 8/9) and extractQueuePatterns (this PR). No conflicts remain.

---

Remaining Concern

queue-extraction.ts:139-152 — Temporal activity names produce spurious queue nodes

// Activity calls: activities.methodName() -- these are ENQUEUES (dispatching work)
if (TEMPORAL_PROXY_ACTIVITIES_RE.test(content)) {
  TEMPORAL_ACTIVITY_CALL_RE.lastIndex = 0;
  while ((m = TEMPORAL_ACTIVITY_CALL_RE.exec(content)) !== null) {
    out.push({
      filePath,
      role: 'producer',
      queueName: m[1],   // ← 'validateOrder', 'chargePayment', 'sendConfirmation'
      ...
    });
  }
}

For the fixture workflow.ts, this creates three CodeElement nodes — validateOrder, chargePayment, sendConfirmation — none of which correspond to actual Temporal task queues. The real task queue ('orders') is already correctly extracted from starter.ts via client.workflow.start. These three nodes are pure noise in the graph.

The cleanest fix is to remove the activity call detection block entirely (lines 139-152). The task queue connection is already established through the workflow starter path — the activity call path adds no meaningful graph information and only inflates CodeElement counts with method names. Fix this →

---

Minor Notes (Non-blocking, carried from previous reviews)

new Worker false-positive trigger (queue-extraction.ts:69): content.includes('new Worker') fires for worker_threads / Web Workers. The downstream BULLMQ_WORKER_RE regex is specific enough to avoid false edges — this is CPU cost only, not a correctness issue.

Weak test assertions: Tests use toBeGreaterThanOrEqual(1). The proxyActivities guard test (queue-detection.test.ts:49) checks reasons.some(r => r.includes('producer')) — this passes trivially on any BullMQ edge and doesn't specifically verify the Temporal guard works. Neither test verifies that spurious activity-method nodes are absent.

500-char taskQueue lookahead (queue-extraction.ts:124): Silently falls back to workflow function name for unusually long option objects. Acceptable for real-world code but would be safer with a comment noting the limitation.

---

What's Working Well

• BullMQ producer/consumer detection is complete and correct — variable tracking (new Queue('name') → q.add()) resolves queue names before creating edges
• Deduplication — graph.getNode(qid) in call-processor.ts:1655 prevents duplicate queue nodes across chunks
• Edge ID includes lineNumber (call-processor.ts:1658) — prevents collision when a file enqueues the same queue multiple times
• Schema changes are consistent — REL_TYPES, RelationshipType union (types.ts:109-110), and all processor imports are aligned
• Shared utility is clean — queue-extraction.ts has a single export, O(n) lineAt implementation, good inline comments

---

Summary

This is the third review pass. BullMQ detection is solid and production-ready. The single outstanding issue (Temporal activity-method nodes) is semantic noise, not a BullMQ regression. If Temporal correctness is in scope for this PR, remove lines 139-152 from queue-extraction.ts and the PR is fully clean. If it can be tracked as a follow-up, the PR is mergeable today as BullMQ is the primary use case.

Deep Performance & Bug Review

Tasks

• Gather context and understand the PR
• Read all changed files in depth
• Analyze queue-extraction.ts — regex correctness, performance, edge cases
• Analyze call-processor.ts — node/edge creation, deduplication, correctness
• Analyze pipeline.ts and parse-worker.ts — threading, fallback paths
• Analyze parsing-processor.ts — data flow correctness
• Review test fixtures and integration test coverage
• Verify identified issues against actual code
• Post comprehensive performance & bug findings

---

Verdict: 3 verified bugs, 3 performance issues, 4 test coverage gaps

The two previous reviews focused on architecture and Temporal semantics. This pass goes deeper into regex correctness, edge creation correctness, and actual runtime behavior. All findings below were verified against the current code on feat/async-queue-detection.

---

🔴 Bug 1: Queue names with colons (or other special chars) silently produce no edges

File: queue-extraction.ts:12,18

Both BULLMQ_QUEUE_DECL_RE and BULLMQ_WORKER_RE use \w[\w-]* to capture the queue name:

const BULLMQ_QUEUE_DECL_RE = /(?:const|let|var)\s+(\w+)\s*=\s*new\s+Queue\s*\(\s*['"](\w[\w-]*)['"]/g;
const BULLMQ_WORKER_RE     = /new\s+Worker\s*\(\s*['"](\w[\w-]*)['"]/g;

\w[\w-]* matches [a-zA-Z0-9_] followed by zero or more [a-zA-Z0-9_-]. For queue names like 'payments:high-priority', the \w[\w-]* group matches payments, but then the regex expects a closing quote — finds : instead — and the entire match fails silently. No error, no partial match, no edge.

This affects a common real-world BullMQ pattern. Colon-namespaced queues ('orders:europe', 'jobs:batch:large') are idiomatic in multi-tenant BullMQ deployments.

// These will NOT produce any ENQUEUES/PROCESSES edges:
const q = new Queue('payments:high');        // ❌ colon
const q = new Queue('my.email.queue');       // ❌ dot
const q = new Queue('retry queue v2');       // ❌ space

// This works:
const q = new Queue('video-processing');     // ✓ hyphen only

Fix: replace \w[\w-]* with [^'"]+ in both regexes. Fix this →

---

🔴 Bug 2: ENQUEUES/PROCESSES edges created from File IDs that may not exist in the graph

File: call-processor.ts:1657-1659

const fid = generateId('File', pt.filePath);
graph.addRelationship({ id: ..., sourceId: fid, targetId: qid, ... });

There is no graph.getNode(fid) check before creating the relationship. If the source file was skipped (binary detection, size limit, unsupported language, I/O error), no File node exists for fid, yet the edge is added with a dangling sourceId. Compare this with the queue node creation on line 1654-1655, which correctly checks if (!graph.getNode(qid)) before adding.

This is inconsistent, and every other edge-creation site in the codebase checks node existence before creating edges. The result is ENQUEUES/PROCESSES edges pointing to ghost file nodes, which corrupts impact analysis results.

🟠 Bug 3: Temporal activity method names still used as queueName (unfixed after 3 review rounds)

File: queue-extraction.ts:147

This was flagged in both previous reviews and is still present:

// queue-extraction.ts:143-151
while ((m = TEMPORAL_ACTIVITY_CALL_RE.exec(content)) !== null) {
  out.push({
    role: 'producer',
    queueName: m[1],    // ← 'validateOrder', not a real queue name
    handlerName: m[1],
    lineNumber: lineAt(content, m.index),
  });
}

For workflow.ts in the fixture, this produces 3 CodeElement nodes: validateOrder, chargePayment, sendConfirmation — none are real Temporal task queues. The actual task queue ('orders') is already correctly captured from starter.ts. These nodes are pure noise and inflate queue counts in every graph that has Temporal workflows.

The fix is to remove lines 139-152 entirely — the activity detection block adds no meaningful information beyond what TEMPORAL_WORKFLOW_START_RE already captures from client.workflow.start. Fix this →

🟡 Performance Issue 1: lineAt() is O(file_size) per match, not O(file_size) total

File: queue-extraction.ts:48-54

function lineAt(content: string, index: number): number {
  let count = 0;
  for (let i = 0; i < index; i++) {   // scans from 0 every time
    if (content.charCodeAt(i) === 10) count++;
  }
  return count;
}

For a file with k pattern matches, this runs in O(k × file_size) total. The previous review comment ("O(n) lineAt is in place") was comparing against the old substring(...).split('\n') approach (which allocated strings/arrays), not fixing the algorithmic complexity. A correct O(n)-total approach tracks a running position and requires matches to be ordered — which they are, since regex .exec() with g flag advances left-to-right.

For typical files with 1-5 queue calls this is negligible, but for generated files or minified output with many references, it compounds.

🟡 Performance Issue 2: new Worker guard triggers BullMQ scan on every web worker or worker_threads file

File: queue-extraction.ts:69

const hasBullMQ = content.includes('new Queue') || content.includes('new Worker');

content.includes('new Worker') is true for:

• new Worker(new URL('./worker.js', import.meta.url)) — web worker
• new Worker(filename, { workerData }) — Node.js worker_threads

Both are common and unrelated to BullMQ. When hasBullMQ is true, all 3 BullMQ regexes are executed against the file content even though they'll match nothing. For repos heavy on worker_threads (common in Node.js services), this adds meaningful CPU overhead on the hot path.

A tighter guard would be: content.includes("from 'bullmq'") || content.includes('require(\'bullmq\')').

🟡 Performance Issue 3: One ENQUEUES edge per .add() call, not per unique (file, queue) pair

File: call-processor.ts:1656-1659

The current design creates a separate edge for each q.add(...) call:

graph.addRelationship({
  id: generateId(rt, fid + '->' + qid + ':' + pt.lineNumber),  // distinct per line
  ...
});

A file calling .add() 50 times on the same queue creates 50 ENQUEUES edges. For graph queries that ask "which files produce to this queue?", they'd need to dedupe(enqueues.map(e => e.sourceId)). The semantic meaning of ENQUEUES is a binary relationship (this file enqueues to this queue), not a call-count. Multiple edges bloat the graph and make traversal queries less predictable.

This is a design choice, but worth an explicit decision. The HANDLES_ROUTE/FETCHES edges elsewhere use one-per-route, not one-per-call.

🔵 Test Coverage Gap 1: No test for colon-containing queue names (would catch Bug 1)

The fixture uses 'video-processing' (hyphen-only). A test with new Queue('orders:high') would have caught Bug 1 immediately. This gap means Bug 1 could exist in production undetected.

---

🔵 Test Coverage Gap 2: proxyActivities guard test is vacuous

File: queue-detection.test.ts:49-57

it('uses proxyActivities guard for Temporal activity detection', () => {
  const reasons = enqueues.map((r: any) => r.reason);
  expect(reasons.some((r: string) => r.includes('producer'))).toBe(true);
});

This test passes if there is any single ENQUEUES edge with reason containing 'producer'. Since every BullMQ producer edge has reason: 'producer-add', this test passes trivially without the Temporal guard doing anything at all. It doesn't verify the guard prevents false positives on non-Temporal activities objects. A meaningful test would check that activities.foo() in a file without proxyActivities produces zero ENQUEUES edges.

---

🔵 Test Coverage Gap 3: No test for the File-node-existence scenario (Bug 2)

There is no test verifying that skipped or unindexed files do not create dangling ENQUEUES/PROCESSES edges.

---

🔵 Test Coverage Gap 4: No deduplication test

No test verifies that two files referencing the same queue name ('video-processing') produce one CodeElement queue node, not two.

---

✅ What's confirmed solid

• No double-extraction in sequential fallback path: verified the chunkWorkerData === null check is mutually exclusive with sequentialChunkPaths — worker-processed chunks never re-run extraction
• lastIndex reset before each global regex: all 5 g-flag regexes correctly reset lastIndex = 0 before their loop — no stale state across calls
• allQueuePatterns scope: declared at function scope (lines 670) before the try block (line 672) — not a block-scoping issue despite the inconsistent indentation
• Queue node deduplication: graph.getNode(qid) check at call-processor.ts:1654 correctly prevents duplicate CodeElement nodes
• BullMQ producer-consumer linking: variable-name tracking (queueVarMap) correctly links const q = new Queue(...) to q.add(...) calls on the same variable

⚠️ Upcoming Prettier formatting — rebase instructions

PR #563 adds Prettier as the code formatter for the repo. When it merges, the bulk format commit will touch ~350 files (style-only: whitespace, quotes, trailing commas). Your branch will likely conflict.

After #563 merges, rebase your branch:

git fetch origin
git checkout <your-branch>
git rebase origin/main

# Conflicts will be formatting-only — accept your version:
git checkout --theirs .
git add .
git rebase --continue

# Then re-format your branch to match the new style:
npx prettier --write .
git add -A
git commit -m "style: apply prettier formatting"
git push --force-with-lease

New setup step: Run npm install at the repo root (not just in gitnexus/) to get prettier + activate the pre-commit hook. The hook auto-formats staged files on every commit going forward.
