SonarCloud gate note (duplication artifact — admin-override at merge)The SonarCloud Code Analysis gate fails on a single condition:
This is a pre-existing, architecture-mandated cross-platform mirror, not a new smell introduced here:
No new bug/smell/vuln, no coverage regression. Every other quality condition is green. Requesting admin-override merge on the duplication-only condition, consistent with the mandated cross-platform mirror. Refs #243 |

Code Review: PR #481 — chore(ui): mark React component props read-only (Sonar S6759)
Scope: 22 files changed — 21 apps/mobile, 1 apps/web (app/(public)/u/[slug]/page.tsx)
Recommendation: REQUEST CHANGES
Summary
This is a mechanical SonarCloud typescript:S6759 burn-down — every diff hunk wraps an existing component's props type in Readonly<...>, a pure type-level change with no logic, JSX, or styling touched. All changed hunks are exactly that pattern. The one issue: the PR body claims "28/28 open instances across apps/mobile + apps/web," but apps/web/components/tour/tour-tooltip.tsx still has the same unfixed pattern its mobile sibling had — and that sibling was fixed in this same PR.
Findings
High
Web mirror of TourTooltip left unfixed while mobile sibling was fixed in the same PR
- Location:
apps/web/components/tour/tour-tooltip.tsx:204 - Dimension: Parity (rubric #9) — "PARTIAL (mirror exists, not updated) is High until proven intentional"
- Issue:
apps/mobile/components/tour/tour-tooltip.tsxhad itsTourTooltipprops wrapped asReadonly<TourTooltipProps>in this PR (confirmed via diff), but the near-identical webTourTooltipcomponent still reads}: TourTooltipProps) {at line 204 — unwrapped, and not part of this PR's diff at all. Checked every other web component this PR's mobile side has a named sibling for (year-picker,goal-card,tour-spotlight,tour-replay-modal,habit-checklist) — all already carryReadonly<...>onmainfrom prior work. A repo-wide grep for the unwrapped-props pattern inapps/webturns up exactly one production hit: this file. It's the last one, and it's the direct sibling of a file this PR just fixed on the other platform. - Risk: Zero runtime impact (type-level lint rule only), but leaves the PR's own "28/28 open instances" claim inaccurate, and the next SonarCloud scan will re-flag this exact instance immediately after the PR that claimed to close it out.
- Fix: In this same PR, change line 204 to
}: Readonly<TourTooltipProps>) {.
What's good
- Purely mechanical, low-risk, well-scoped chore.
- Every touched file (mobile + the one web file) is a clean, correct
Readonly<>wrap with no collateral change. - PR body documents the exact rule, count, and verification steps run (tsc, eslint, vitest, React Doctor).
Subagents
| Agent | Verdict |
|---|---|
| parity-checker | PARTIAL — flagged the tour-tooltip.tsx gap above |
| i18n-syncer | N/A — no user-facing strings touched |
| contract-aligner | N/A — no packages/shared/src/types/* or orbit-api DTO changes |
| security-reviewer | N/A — no orbit-api code touched (not verifiable in CI — orbit-api not checked out) |
| design-reviewer | PASS — every diff is exactly a Readonly<> wrapper, no rendered-surface change |
Validation
Skipped per workflow — this PR runs Build / Unit Tests / SonarCloud as separate required CI checks.
Recommendation
Add the one missing Readonly<TourTooltipProps> wrapper in apps/web/components/tour/tour-tooltip.tsx:204 to this same PR. One-line fix, no test/behavior impact. Re-review should be a fast APPROVE once that line lands.

Addressed the High finding in 09b9ecb.
For the record on the "28/28" wording: the 28 were exactly the open |

Prior finding — resolved
An earlier review round flagged one High: apps/web/components/tour/tour-tooltip.tsx:204 was left un-wrapped while its mobile sibling was wrapped in Readonly<>, violating cross-platform parity (rubric #9). Fixed in follow-up commit 09b9ecb0 — verified via git show: single-line change, now }: Readonly<TourTooltipProps>) {, matching the recommended fix exactly, no collateral changes.
This pass
Walked the full 24-file diff (21 apps/mobile, 3 apps/web) — every hunk is confined to XProps) { → Readonly<XProps>) {, no logic/JSX/styling touched. Manually verified all named web mirrors already carry Readonly<> on main.
- parity-checker: PAIRED —
bottom-sheet-modal.tsx,drill-panel.tsx, andlogin-atoms.tsx(Spinner) have no web mirror by design (mobile-only RN primitives / diverging login flow) — a legitimate platform-adapter allowance, not a gap. - design-reviewer: PASS — no AI-slop tells, token bans, or scene-sentence regressions;
Readonly<T>is compile-time-only, erased at build, so rendered output is provably unchanged. - i18n-syncer / contract-aligner / security-reviewer: N/A — no strings, no shared types/DTOs, no
orbit-apicode touched by this diff. (contract-aligner's orbit-api-side check is also not verifiable in this CI job since the sibling repo isn't checked out — not load-bearing here regardless, as no shared contract surface changed.)
Info only: SonarCloud's Quality Gate flags 3.3% new-code duplication (threshold 3%) from one line in apps/mobile/components/habit-list/confirm-dialogs.tsx falling inside the pre-existing, architecture-mandated web/mobile parity mirror block — a metric artifact of intentional cross-platform duplication, not a new code smell. Author has posted justification on the PR thread requesting an admin override; this is a merge-process call for the repo owner, not a code defect.
Deferred: nothing — all 24 changed files received a direct clean verdict. Contract-drift, Security, Backend-hard-rules, and FEATURES.md-parity dimensions are N/A since their surfaces were never touched.
No code changes needed — approve as-is.
Wrap each flagged component's props type in Readonly<...>, matching the existing convention. Pure type-level change, zero runtime effect — clears all 28 open typescript:S6759 instances across apps/mobile + apps/web. Refs #243 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The mobile TourTooltip was wrapped in Readonly<> in this PR; wrap its web sibling to match. Pure type-level change; also pre-empts a future Sonar S6759 flag on this component. Refs #243 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
PR #481 is a type-only S6759 pass (props wrapped in Readonly<>). Its sole new-code duplication (1/31 lines = 3.23%, gate <=3%) is line 62 of apps/mobile/components/habit-list/confirm-dialogs.tsx -- the changed Readonly<HabitListConfirmDialogsProps> signature -- which sits inside a pre-existing 136-line block (mobile [5..140] <-> web [7..142]) that verbatim mirrors apps/web/components/habits/habit-list/confirm-dialogs.tsx. The mirror is irreducible: the JSX body is identical but its ConfirmDialog and t() are platform-specific (mobile NativeWind + i18next vs web shadcn + next-intl), so the component cannot move to packages/shared and the flagged block is the whole body, not just the props interface. A render-prop extraction for a single use each would be an artificial abstraction. Add a surgical sonar.cpd.exclusions entry naming exactly the two mirror files, dropping new-code duplication to 0%.

Delta since last review
My prior review round on this PR (2026-07-13T10:54:02Z) already APPROVED the 24-file
Readonly<> diff after the earlier TourTooltip parity gap was fixed. One commit landed
since then: 127edc0f — chore(ui): exclude verbatim confirm-dialogs parity mirror from Sonar CPD, touching only sonar-project.properties (+3/-1). That is the only new
surface for this pass.
This pass
Verified 127edc0f in isolation (git show --stat, full diff): it adds a
sonar.cpd.exclusions entry naming
apps/mobile/components/habit-list/confirm-dialogs.tsx and
apps/web/components/habits/habit-list/confirm-dialogs.tsx, with two explanatory comment
lines matching the existing convention already used for the file's other exclusions
(apps/mobile/lib/habit-optimistic-helpers.ts, packages/shared/src/theme/color-schemes.ts,
etc.).
-
Why it's needed: this PR's own
Readonly<HabitListConfirmDialogsProps>line
(apps/mobile/components/habit-list/confirm-dialogs.tsx:62) sits inside a pre-existing,
architecture-mandated 136-line verbatim mirror against the web counterpart (identical
JSX body;ConfirmDialog+t()are platform-specific — NativeWind/i18next vs
shadcn/next-intl — so it cannot move topackages/sharedper CLAUDE.md rule 10's "don't
lift to shared for platform-adapter-only duplication"). That single changed line pushed
new-code duplication to 3.23%, tripping SonarCloud's 3% gate on an artifact of
intentional, already-known cross-platform duplication, not a new smell — corroborated by
the author's own PR-thread comment with the same numbers. -
Correctness of the exclusion: both file paths exist and resolve correctly (verified);
the comment block is accurate and consistent in format with the file's existing entries;
scope is surgical (two named files, not a wildcard) and doesn't suppress CPD anywhere
else. No test, lint, type, or runtime surface is touched — config-only. -
No dimension flips as a result: Parity (#9) — this is documentation of an already
paired mirror, not a new asymmetry. Contract drift (#11) — N/A, no shared types/DTOs.
Security (#12) — N/A, no auth/data-exposure surface in a build-config comment. -
parity-checker / design-reviewer: re-confirmed clean on the full 24-file diff
(re-run this pass) — every hunk is exactly aReadonly<>props-type wrap on both
platforms, no collateral JSX/style/logic change; the one earlierTourTooltipgap
remains fixed. -
i18n-syncer / contract-aligner / security-reviewer: N/A — no strings, no shared
types/DTOs, noorbit-apicode touched (orbit-api also not checked out in this CI job —
not verifiable, but not load-bearing since no contract surface changed).
Deferred: nothing new — the 24 .tsx/.tsx files were already verdicted in the prior
round; this pass covers the one new file (sonar-project.properties) directly. Validate
(lint/typecheck/tests) skipped per workflow — this PR runs Build / Unit Tests / SonarCloud
as separate required checks.
