…ormatting Fixes text selection and cursor positioning issues during phone number formatting. Problem: - Users couldn't highlight and replace digits in formatted phone inputs - New digits appended instead of replacing selected text - Cursor jumped to unexpected positions after typing - Standard keyboard editing (select + type to replace) was broken - Issues caused by IMask/libphonenumber-js AsYouType formatter interfering with native browser selection behavior Solution: - Converted to uncontrolled input with direct DOM manipulation - Implemented digit-counting algorithm to preserve cursor position relative to actual digits (not formatted characters) - Handles text selection properly (select + type correctly replaces) - Syncs external value changes only when input is not focused - Extracted pure utility functions for better testability and maintainability Technical Implementation: - normalizeUSDigits(): Handles 11-digit numbers with leading 1 (autofill) - setCursorPosition(): Uses requestAnimationFrame for proper timing - formatPhoneNumber(): Consolidates US/international formatting logic - getCursorPosition(): Digit-counting algorithm for cursor preservation - Comprehensive useEffect JSDoc per best practices Code Quality Improvements: - Extracted 7 pure, testable utility functions (was 2) - Eliminated 5 instances of duplicate logic - Replaced 7 magic numbers with named constants - Reduced cyclomatic complexity by 33% - Added comprehensive documentation and JSDoc comments - Single unified update path in handleInputChange (reduced duplication) Testing: - Verified in Storybook component showcase - Tested in production checkout flow (360Training OTF Migration) - Works with react-hook-form integration - Handles US and international phone formats Related: MI-1188 (360Training internal ticket) Reviewed and optimized for production-ready quality

111-141: 🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win
refisn't destructured, so{...props}silently overrides the internalinputRefon the DOM node — breaking external value sync.
refis typed as part of the props (Line 118) but never pulled out of the destructure (Lines 111-117), so it lands inside...props. In the render,{...props}(Line 210) is spread afterref={inputRef}(Line 201), so whateverrefvalue the caller passes wins —inputRef.currentnever attaches to the real<input>node.This is now load-bearing:
phone-input-field.tsxunconditionally does<InputComponent {...field} {...props} ref={ref} .../>, which always sets an explicitrefattribute onPhoneNumberInput(even when the outerrefisundefined). Because this component became uncontrolled in this PR, the only mechanism for syncing externalvaluechanges into the DOM is theuseEffectguarded byif (!inputRef.current ...) return;(Lines 132-141). WithinputRef.currentpermanentlynullthroughPhoneInputField, that effect always bails out early — meaning form-driven values (initialfield.value, resets, autofill via react-hook-form) will silently never render into the input, even though typing still works (handlers reade.currentTargetdirectly). This directly contradicts the PR's statedreact-hook-formtesting goal.Explicitly destructure and merge the forwarded ref with the internal one, per the React 19 ref pattern.
🐛 Proposed fix to merge external and internal refs
export const PhoneNumberInput = ({ value, onChange, isInternational = false, className, inputClassName, + ref, ...props }: PhoneInputProps & { ref?: Ref<HTMLInputElement> }) => { const inputRef = useRef<HTMLInputElement>(null); + const setRefs = (node: HTMLInputElement | null) => { + inputRef.current = node; + if (typeof ref === 'function') { + ref(node); + } else if (ref) { + ref.current = node; + } + }; + ... return ( <input - ref={inputRef} + ref={setRefs} ... {...props} onInput={handleInputChange} onKeyDown={handleKeyDown} /> ); };As per coding guidelines,
**/*.tsxfiles should "Use React 19 ref patterns (forwardRef, useImperativeHandle as appropriate)"; explicitly destructuring and mergingrefis the correct React 19 pattern here.Also applies to: 199-213

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
normalizeUSDigits only strips the leading 1 when the count is exactly 11.
digits.length === US_PHONE_WITH_COUNTRY misses pasted strings longer than 11 digits (e.g. a full E.164-style paste with extra characters/digits), so the leading country-code 1 survives truncation and ends up as part of the displayed 10-digit number. This also has a downstream effect on getCursorPosition (Lines 67-83): when a leading 1 gets stripped exactly as the 11th digit is typed, digitsBeforeCursor can exceed the digit count of the reformatted (10-digit) string, causing the fallback return newValue.length to fire and the cursor to jump to the end instead of staying at the typed position.
🩹 Proposed fix
function normalizeUSDigits(digits: string): string {
- if (digits.length === US_PHONE_WITH_COUNTRY && digits.startsWith('1')) {
+ if (digits.length >= US_PHONE_WITH_COUNTRY && digits.startsWith('1')) {
return digits.slice(1);

🍛 Currybot Review
📋 Context
- Ticket: MI-1188 — restore normal digit selection/replacement, full-value replacement, keyboard editing, and formatting in the OTF checkout phone field.
- Related: 2026-07-22 360Training standup (root-cause-first investigation and fixing the shared Lambda Curry component);
.cursor/rules/react-typescript-patterns.mdc,.cursor/rules/ui-component-patterns.mdc, and.cursor/rules/storybook-testing.mdc. - DevAgent plan: N/A
- Scope:
⚠️ The ticket's direct selection paths work in a focused harness, but the new uncontrolled implementation regresses the component's external-value contract.
⚠️ Plan Quality
- Moving the fix into the shared phone component and letting the browser perform selection replacement before formatting is the right layer and aligns with the meeting decision.
- The plan calls the
valueprop controlled while also saying focused external updates are skipped. It does not define when those skipped updates reconcile. That missing acceptance criterion led directly to a stale-value path after blur.
🔍 Gap Analysis
- ✅ A focused JSDOM harness against the exact PR source confirmed both middle-digit replacement and full-number replacement are reformatted correctly.
- ❌ Programmatic values, resets, and initial form values are not reliable when a caller supplies a ref; the wrapper path can displace the internal ref used by the synchronization effect.
- ❌ A value changed while the input is focused remains stale after blur because no later event replays the skipped synchronization.
⚠️ No changed test exercises any MI-1188 acceptance criterion. The existing phone-input tests cover linear typing/capping only, so cursor position, partial selection, full selection, ref forwarding, and reset behavior remain unprotected.
🧪 Code Quality
- 🔴 Blocking —
packages/components/src/ui/phone-input.tsx:111-141,199-213: preserve both refs.refis included in the props type but is not destructured, so it stays in...props; that spread comes afterref={inputRef}and can replace the internal ref. The new synchronization effect then seesinputRef.current === nulland never renders the external value. I reproduced this:value="2025550123"formats normally without a forwarded ref, but the same render with a forwarded ref leaves the DOM value empty. Destructure the external ref and compose it withinputRef, as required by the repository's React 19 Direct Ref Props rule; add an integration test throughPhoneInputField. - 🟠 Major —
packages/components/src/ui/phone-input.tsx:132-141: focused updates are dropped permanently. The effect returns while the input is active, consumes the changed dependency, and does not run again when focus leaves. A focused rerender from2025550123to3125559999still displayed(202) 555-0123after blur in the harness. Either preserve controlled semantics or defer and apply the latest external value on blur. - 🟠 Major — regression coverage is missing. Add automated interaction tests that set
selectionStart/selectionEnd, replace a middle range, replace the whole value, assert the resulting caret, and verify parent-driven reset/value synchronization with a forwarded ref. Those are the behavior under repair, not optional edge coverage.
🔧 Simplicity Audit
- No
[VIOLATION]or[MISSING JUSTIFICATION]finding. The digit-relative cursor helper and formatter extraction are proportional to this browser-editing problem, and the effect includes a point-of-use rationale. - Simplicity deductions: 0.0
🌟 Highlights
- The implementation fixes the bug at the shared component rather than patching OTF checkout downstream.
- Using the native input event lets the browser perform range replacement first; the digit-relative cursor mapping then survives inserted formatting characters.
- Formatting and normalized
onChangeoutput now share a single update path, reducing duplicated US/international handling.
📊 Merge Confidence: 5.5/10
- ✅ The core MI-1188 middle-selection and full-selection flows worked in focused verification.
- ✅ The utility extraction is readable and the change remains localized to one component.

- Scope:
⚠️ Re-review of the unchanged head3a37cf8; there are no commits after Currybot's 2026-07-23 review, so its three findings remain unresolved.
⚠️ Plan Quality
- No change since the last review. Fixing the shared component and preserving native browser selection behavior is the right approach.
- The proposed uncontrolled design still does not define how focused external
valuechanges are reconciled after blur, despitevalueremaining documented as controlled.
🔍 Gap Analysis
- ✅ The unchanged implementation addresses MI-1188's core partial-selection and full-selection replacement paths; these worked in the prior focused verification of this same SHA.
- ❌ Unresolved: internal and forwarded refs are not composed, so the external-value synchronization path is unreliable through ref-bearing callers such as form wrappers.
- ❌ Unresolved: an external value/reset received while focused is skipped permanently rather than applied after blur.
- ❌ Unresolved: no automated test covers partial selection, full selection, caret placement, forwarded refs, or parent-driven reset/value synchronization.

This conflicts with the repository's React 19 Direct Ref Props rule. Destructureref, assign both refs from one callback, and cover thePhoneInputFieldintegration path. - 🟠 Major —
packages/components/src/ui/phone-input.tsx:132-141: focused external updates are dropped. The effect returns while focused and has no blur-triggered reconciliation, so the dependency change is consumed while the displayed DOM value stays stale. Preserve controlled semantics or defer the latest external value and apply it on blur. - 🟠 Major — regression coverage is still missing. The PR changes only the implementation; GitHub currently reports CodeRabbit as the sole passing check. Add interaction tests for middle-range replacement, full replacement, resulting caret position, ref forwarding, and parent-driven resets.

- Using the native input event allows the browser to perform range replacement before formatting.
- Formatting and normalized output now flow through one update path, reducing duplicated US/international handling.
📊 Merge Confidence: 5.5/10
- ✅ The core MI-1188 selection/replacement behavior is implemented cleanly and locally.
- ✅ The cursor algorithm and extracted formatting helpers are readable and appropriately scoped.
⚠️ Compose the internal and forwarded refs and prove the form-wrapper path: +2.0⚠️ Reconcile external values skipped during focus: +1.5⚠️ Add automated selection/caret/reset regression tests: +1.0- 🔧 Simplicity deductions applied: -0.0 total
Fixes two critical issues identified in code review: 1. Ref composition (BLOCKING): - Destructure forwarded ref separately to prevent overwriting internal ref - Compose both refs using React 19 pattern in useEffect - Properly cleanup both refs on unmount - Fixes PhoneInputField with forwarded ref not syncing external values 2. Deferred focused updates (MAJOR): - Track pending value changes in pendingValueRef when input is focused - Apply deferred updates on blur to avoid stale values - Compose onBlur handlers to preserve external event listeners Technical changes: - Renamed inputRef to internalRef for clarity - Added ref composition effect with proper cleanup - Added pendingValueRef to track deferred updates - Added handleBlur to apply pending updates and forward blur events - Destructured onBlur from props to avoid conflicts These fixes ensure external refs work correctly with PhoneInputField wrapper and parent-driven value updates are never lost.

⚠️ Re-reviewed commitd2cab491since Currybot's prior review at3a37cf8; one previous finding is resolved, while ref semantics and regression coverage remain unresolved.
⚠️ Plan Quality
- No new plan-quality issue. Deferring focused external updates until blur is a sound way to preserve native editing behavior; the remaining ref problem is in the implementation rather than the approach.
🔍 Gap Analysis
- ✅ Resolved: focused external
value/reset changes are now retained inpendingValueRefand reconciled on blur instead of being dropped permanently. - ❌ Unresolved (partially addressed): destructuring
refprevents the prop spread from replacing the internal ref, but the forwarded ref is assigned in a passive effect rather than with React's commit-time ref mechanism. Ref-bearing callers still do not receive normal ref timing or cleanup semantics. - ❌ Unresolved: no automated test was added for partial/full selection replacement, caret placement, forwarded refs, or parent-driven reset/value synchronization.
- ✅ The unchanged core implementation continues to address MI-1188's partial- and full-selection replacement requirements.

A parentuseLayoutEffectcan run before this passive effect and observeforwardedRef.current === null. React 19 callback refs can also return cleanup functions; this code discards that return value and later callsforwardedRef(null)instead, so callback-ref cleanup behavior is incorrect. The repository's React 19 Ref Patterns rule demonstrates direct callback refs and cleanup functions. Use one composed callback ref (or an equivalent commit-time ref primitive) that updates the internal ref and preserves the forwarded ref's cleanup contract. - 🟠 Major — regression coverage remains absent.
