Evidence

Evidence: demonstrated — the Security Agent audit report ran inside the Android dev client against the local stack on this machine at this head and shows the backend's date-only period end as its calendar day, with the emulator clock west of UTC and again east of it. The shared parser itself was exercised by the package suite, which resolves a YYYY-MM-DD value to that calendar day's local midnight in America/Los_Angeles, Asia/Tokyo, and UTC.

Change

• packages/app-shared/src/utils.ts resolves a YYYY-MM-DD value to local midnight of that calendar day, so default local formatting shows that day. A date that does not exist in its month stays an invalid Date, so callers that check for one keep their fallback; four-digit years below 100 keep their year; a missing value stays an invalid Date.
• apps/mobile/src/components/security-agent/audit-report-screen.tsx formats the report's date-only displayEnd with the existing formatCalendarDate helper, so the header and the empty state show the report's calendar day, while generated and event clocks keep formatUtcTimestamp.
• packages/app-shared/src/utils.test.ts covers America/Los_Angeles, Asia/Tokyo, and UTC, a day that does not exist in its month, a four-digit year below 100, a missing value, and timestamp instants.
• The audit-report mounted suites mock the formatter the header now calls.

Android dev client against the local stack

Dev client com.kilocode.kiloapp on the emulator, Metro serving this checkout, Next.js on localhost:3000 over adb reverse, signed in to the local dev stack. The backend answers securityAgent.getAuditReport with a date-only period end:

"period": { "start": "2026-07-30T00:00:00.000Z", "endExclusive": "2026-10-28T00:00:00.000Z",
            "displayEnd": "2026-10-27", "timeZone": "UTC" }

With the emulator clock west of UTC, where the local calendar date was still the previous day, the accessibility dump of the report header reads:

text="7/30/2026 – 10/27/2026 · UTC"

With the emulator clock east of UTC, where the local calendar date was already the next day, the same dump reads:

text="7/30/2026 – 10/27/2026 · UTC"
text="Generated 10/27/2026, 12:03 PM UTC"

The date-only period end renders the report's calendar day in both device zones; the generated clock keeps its instant. The screenshot below is the eastern-zone capture of that screen.

Parser behavior in the package suite

The same parser is exercised under three time zone settings in packages/app-shared/src/utils.test.ts, at the head that CI runs:

America/Los_Angeles  2026-09-26 -> local hour 0, renders 9/26/2026
Asia/Tokyo           2026-09-26 -> local hour 0, renders 9/26/2026
UTC                  2026-09-26 -> local hour 0
2026-02-30 and 2026-13-01 -> Invalid Date
2026-03-16 15:21:40.957+00 -> the same instant in Los Angeles and Tokyo

Limitation: no product screen feeds a date-only backend value through the shared parser and then formats it in the device zone, so the parser's zone behavior is proven by the package suite rather than through a screen. The audit report carries the only date-only field on a mobile screen, and the device run above exercises that screen.

Production prerequisites

None.

Proxy answers

The owner's proxy gave these answers in the owner's place.

1. Question: Parser semantics: For a date-only input like 2026-09-26, what should the shared parseTimestamp return?
   Answer: Local-midnight calendar Date
   Confidence: 0.75 · Precedent: Fix the root cause and the class of the issue: "fix class of issue preventing progress" (7f3470e0ba6f). The work item also asks for a local-midnight Date.
2. Question: Invalid dates: When a date-only string names a day that does not exist (e.g. 2026-02-30), what should parseTimestamp do?
   Answer: Preserve Invalid Date (Recommended)
   Confidence: 0.80 · Precedent: Fix the root cause on every affected surface (session 7f3470e0ba6f: "fix class of issue preventing progress"). Keeping Invalid Date leaves existing caller fallbacks working and avoids silently showing the wrong day.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental commit adds the formatCalendarDate mock to the audit-report evidence suite, matching the formatter the screen now calls, and the net PR diff keeps the parser and both mobile test mocks consistent. No memory-leak risk: the change adds no listeners, timers, subscriptions, or retained caches.

Assumptions: [INFERENCE] none. The main merge in d687836a6 contributes no PR-scoped changes; review focused on the net PR diff against 0d5416bd8.

Previous review (commit d8978a0)

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental commit resolves both prior findings: parseTimestamp now preserves four-digit years below 100 via setFullYear, and the timezone tests assert the resulting UTC instant, so they would fail if the zone stub stopped applying. The new Date(0)/setFullYear/setHours sequence still yields local midnight, and the month/day guard still rejects non-existent days such as 2026-02-30 and 2026-13-01. No memory-leak risk introduced: the change adds no listeners, timers, subscriptions, or retained caches.

Previous review (commit 07f807f)

Status: 2 Issues Found | Recommendation: Address before merge

Executive Summary

The date-only parsing change is sound for the mobile surfaces that consume it, but the parser loses leading-zero years and the new timezone tests cannot prove that the zone stub actually applies.

SUGGESTION

File	Line	Issue
packages/app-shared/src/utils.ts	18	new Date(year, ...) maps years 0-99 to 1900-1999, so 0099-01-01 no longer parses as year 0099; the month/day guard does not catch it.
packages/app-shared/src/utils.test.ts	22	The "west/east of UTC" tests read back through local getters, so they pass even if vi.stubEnv('TZ', ...) has no effect; assert the resulting instant or offset instead.

bot: Android emulator capture of the Security Agent audit report. The period and generated lines render the report's calendar days with its UTC marker. Test data only.

[iscekic]

bot: Android emulator run against local services displayed the audit report period and generated time with the UTC marker. The screen used a single owned fake-account fixture.

[iscekic]

bot: Android emulator run against the local dev stack. The Security Agent audit report renders its period with the UTC marker while the emulator clock is set outside UTC: the device reads Sat Oct 24 (+14), and the period end still renders 10/23/2026, the report's own calendar day. The generated stamp renders 10/23/2026, 10:39 PM UTC from the same run.

Assertion from the accessibility dump captured with the screenshot:

Audit report
E2E Calendar
7/26/2026 – 10/23/2026 · UTC
Generated 10/23/2026, 10:39 PM UTC

Prototype pollution in left-pad

Single owned fake-account fixture, local Postgres and local Next.js; no production services in the path.

bot: Android dev client from this branch against the local stack, signed in to a local test account, on the Security Agent audit report with one seeded finding and one event for that account.

Two captures of the same view with the emulator clock set through two zones, taken after a relaunch in each. The visible lines were asserted from a uiautomator dump taken in the same command as each capture; this environment has no OCR pass, so the dump is the assertion and the images show the same viewport.

Commands used, abbreviated: adb shell service call alarm 3 s16 <zone>, adb shell am force-stop, adb exec-out uiautomator dump /dev/tty, adb exec-out screencap -p.

Shallow review: no critical issues found.

[iscekic]

bot: Verified on the Android dev client against the local dev stack at head 007c37b. The Security Agent audit report shows the report period and the generated time; the accessibility dump reads 7/30/2026 – 10/27/2026 · UTC.

The shared parser is covered by packages/app-shared/src/utils.test.ts under America/Los_Angeles, Asia/Tokyo, and UTC, for a day that does not exist in its month, and for a four-digit year below 100.
