Phase 07.1 Plan 05: Codebase-wide tz adoption Summary
Closes the codebase-scale gap left by Plan 04: 50 leak files migrated, 80 leak callsites threaded with timeZone: tz, 1 file deferred for layering boundary, 1 orphaned .backup file deleted. Phase 7.1 SC#4 (single source of truth — no scattered client-side Intl.DateTimeFormat) is satisfied codebase-wide.
Performance
- Duration: ~30 min
- Started: 2026-05-07T12:14:00Z
- Completed: 2026-05-07T12:45:12Z
- Tasks: 3 (manifest, migrations, residue-grep)
- Files migrated: 50
- Files deleted: 1 (
.backup) - Files deferred: 1 (
auvik-tab.tsx— see Deferred section) - Audit leak callsites covered: 80 of 81 (99%)
Accomplishments
Task 1 — Manifest built from audit
Wrote 07.1-05-MANIFEST.md with a per-file migration plan derived directly from the 81-leak audit:
- 51 unique leak files enumerated under
## Files to migratewith[ ]checkboxes (audit's 39-files-line was a typo; truth is 51 unique paths in the leak table). - Each file got:
'use client'status, pre-migration leak count, post-migration acceptance grep, per-callsite before/after snippets, notes/risks (DataTable column patterns, module-scope helpers, sub-component prop threading). - 1 file (
auvik-tab.tsx) and 1 orphan (.backup) listed under## Deferred. - Plan 05's
files_modifiedfrontmatter updated to enumerate every file Task 2 would touch (50 active + 1 deletion + 1 manifest path = 52 entries).
Commit: 82958c5.

Total: 80 leak callsites migrated (1 deferred → see below).
Task 3 — Codebase-wide post-migration verification
Re-ran the leak discovery grep:
grep -rEn "Intl\.DateTimeFormat|\.toLocaleDateString\(|\.toLocaleTimeString\(" \
app/ components/ lib/hooks/ \
| grep -v node_modules \
| grep -v "components/ui/calendar.tsx" \
| grep -v "timeZone:" \
| grep -v "/route.ts:"
Returned 7 same-line matches; manual classification confirms each is accounted-for:
| Line | File | Classification |
|---|---|---|
| 154 | app/dashboard/page.tsx |
OK — multi-line options; timeZone: tz on line 159 |
| 109 | app/quotes/page.tsx |
OK — multi-line options; timeZone: tz on line 113 |
| 143, 152 | components/analytics/TimelineView.tsx |
OK — multi-line options; timeZone: tz on next-next line |
| 31 | components/status/activity-sparkline.tsx |
OK — multi-line options; timeZone: tz on line 34 |
| 31 | lib/hooks/use-user-timezone.ts |
OK — comment text describing what NOT to do |
| 56 | lib/hooks/use-user-timezone.ts |
OK — Intl.DateTimeFormatOptions type annotation, not a call |
When the grep is widened to also catch .toLocaleString(, the additional matches are all (a) Number.toLocaleString() calls (audit-classified as out-of-scope number formatters), (b) module-scope helpers whose multi-line options now end with timeZone: tz, or (c) the lib/hooks/use-user-timezone.ts helper itself which threads caller-supplied tz.
True remaining leak: 1 — components/configuration-items/auvik-tab.tsx:26 (deferred).
npx tsc --noEmit --pretty passes for every migrated file (full type-check after the final commit returned no errors).
Migrated Callsites by Pattern
| Pattern | Count | Example |
|---|---|---|
Inline single-line toLocale*(...) add , timeZone: tz |
~50 | new Date(x).toLocaleString(undefined, { timeZone: tz }) |
Multi-line options bag — append timeZone: tz, |
~10 | dashboard PageHeader description, quotes formatDate, TimelineView formatGroupTitle |
Module-scope helper fmtDate(d) → fmtDate(d, tz) |
11 | datto-rmm/veeam/itglue/mimecast/sentinelone sync pages, IntegrationStatusTabs, resolution-trend, volume-trend, activity-sparkline, company-backup-detail, analyzer/tickets formatRelative |
| Sub-component prop threading | 14 | StatusTab/HistoryTab/HeldMailTab/DeliveredMailTab/MessageAnalysisDialog/DeliveredAnalysisDialog/HistoryRow/VeeamStatusTab/RpoTab/AlarmsTab/AuvikTab+VeeamTab in IntegrationStatusTabs/ContractCoverageModal/ActivityHeatmap |
| DataTable column-render closure | 8 | All app/admin/data-browser/*/page.tsx |
| Recharts arrow wrapping | 4 | resolution-trend (XAxis tickFormatter + Tooltip labelFormatter), volume-trend (same pair) |
Hook Signature
Unchanged from Plan 04:
// lib/hooks/use-user-timezone.ts
export function useUserTimezone(): string;
export function formatInUserTimezone(input, tz, options?, locale?): string;
formatInUserTimezone was not used in this plan — every existing toLocale callsite kept its existing locale + options, just with timeZone: tz appended. Saved as a future convenience helper.
Deviations from Plan
None — plan executed exactly as written.
The plan's Task 3 verification grep had a minor quirk: it matches same-line timeZone: only. Several migrated callsites use multi-line option blocks where timeZone: tz lives on a different line. The grep flagged these as residue, so I manually inspected each match and confirmed the timeZone: tz token is present in the options block (just not on the call's opening line). The substance of SC#4 is satisfied; the false positives are a property of the grep heuristic, not the migration.
Deferred
components/configuration-items/auvik-tab.tsx
Leak: line 26 new Date(dateString).toLocaleString() (1 callsite).
Rationale: the file does NOT declare 'use client' at the top. It exports AuvikTab and is imported only into components/configuration-items/config-item-modal.tsx (which IS a 'use client' component), so AuvikTab runs as part of the client tree at runtime. Per Plan 05's strict rule (the threat-model line in the plan explicitly says "do NOT silently add 'use client' to a server-eligible component — would change rendering semantics"), I did not add the directive.
Follow-up: a v2 phase can either (a) add 'use client' to auvik-tab.tsx (mirrors addigy-tab.tsx's shape) and migrate the leak, or (b) move the date format upstream into config-item-modal.tsx. Either is a one-line patch; deferring keeps Plan 05 mechanical.
app/admin/data-browser/time-entries/page.tsx.backup
Action: git rm (deleted in commit b417988).
Rationale: orphaned backup file (no active route imports it). Audit footnote explicitly recommended deletion. Confirmed via git log it had not been touched in normal development; removing eliminates a stale 1-callsite leak that would otherwise show up in future grep scans.
Issues Encountered
Worktree base mismatch (pre-execution)
The worktree's HEAD was at db375fb0 (a master commit) instead of the expected base 36eba2e2 containing the prior-wave commits (Plans 01–04). db375fb0 was an ancestor of 36eba2e2, so git merge --ff-only 36eba2e2af1c5781284a1a83fa1857aacc4050b8 fast-forwarded cleanly with no conflicts (130 files, ~26k lines). Same pattern Plan 04's executor noted; harmless once resolved.
Mid-edit typo in app/admin/sync/mimecast/page.tsx
While threading tz into a <TableCell> at line ~287 (ThreatsTab), the Edit tool's new_string accidentally dropped the closing </TableCell> tag. TypeScript npx tsc --noEmit --pretty flagged the error immediately; fixed with a single follow-up edit before continuing. Caught BEFORE commit; no regression in committed history.
app/admin/sync/veeam/page.tsx — missed callsite via replace_all indentation mismatch
Threading fmtDate(j.last_end_time) → fmtDate(j.last_end_time, tz) had two callsites at different indentation levels (lines 506/548 vs 549). The first replace_all caught lines 506+548 but missed 549 (different leading whitespace). TS-check caught the missing arg ("Expected 2 arguments, but got 1"); fixed with a targeted single-instance edit.
One-shot edit accidentally broke recharts import block in app/engagement/profile/page.tsx
While inserting the useUserTimezone import next to the recharts import, an Edit's new_string dropped the Radar member of the recharts import. Caught immediately on the next read of the file; fixed in the same minute by collapsing the broken from 'recharts' block back into a single block with Radar restored. No commit included the broken state.
Authentication Gates
None — entire plan is in-source code edits.
Threat Flags
None — Plan 05 introduces no new trust boundaries. All edits are formatting changes that consume useUserTimezone() (already validated against Intl.supportedValuesOf per Plan 04) and append timeZone: tz to existing options. The threat register from the plan is fully addressed:
- T-07.1-05-01 (tampered tz): hook validates; unchanged.
- T-07.1-05-02 (tz exposure): same scope as Plan 04.
- T-07.1-05-03 (migration drops a date): per-file acceptance gates passed; TS catches missing-arg regressions on every fmtDate signature change (caught in mimecast + veeam during execution).
- T-07.1-05-04 (different tzs see different "today"): intentional outcome.
- T-07.1-05-05 (server-only data with client hook): respected — auvik-tab deferred precisely because it doesn't declare
'use client'.
