🏛️ Markus Keller (@mkeller) — Application Architect
Verdict: ⚠️ Approved with concerns
This is exactly the kind of structural change the codebase needed. The flat-by-type layout (
components/,utils/,services/,stores/) was growing into an unmaintainable mass. Moving to domain packages that mirror the backend gives new contributors a consistent mental model across the full stack. The mappingdocument/→person/→tag/→activity/is exactly what I would have specified.Blockers
None.
Suggestions
1. Domain boundary leak:
statusDotClass/statusLabellive inperson/personFormat.tsbut are consumed bydocument/DocumentStatusChip.svelteDocumentStatusChipimports document-status CSS helpers (statusDotClass,statusLabel) from$lib/person/personFormat. Document status (PLACEHOLDER, UPLOADED, TRANSCRIBED, REVIEWED, ARCHIVED) is a concept owned by the document domain. The fact that these helpers ended up inpersonFormat.tsis a pre-existing smell — but this refactor was the moment to fix it.The correct home is
$lib/document/documentStatusLabel.ts, which already exists and already exportsformatDocumentStatus.statusDotClassandstatusLabelbelong there too. This would make the document domain self-contained.Not a blocker for this PR since it's pre-existing, but I'd file a follow-up issue before this merges and accept the technical debt consciously.
2.
shared/is still a catch-all — acceptable, but track its growthshared/now contains:primitives/,dashboard/,discussion/,help/,actions/,hooks/,server/,services/,utils/. That's 9 sub-packages. Some of these (discussion/,help/) will likely attract more components over time. If a component inshared/starts pulling exclusively from one domain, it's a signal to migrate it.No action required now — just name this risk explicitly in the issue so it doesn't silently re-accumulate the flat-by-type problem.
3. Coverage
includeexpansion invite.config.ts— verify thresholds remain meaningfulThe old coverage scope was
src/lib/utils/**+src/lib/server/**. The new scope issrc/lib/shared/**+src/lib/document/**+src/lib/person/**. That is a significant surface expansion. If existing coverage was 85% over a narrow set of utility functions, it may be well below 80% over the broader domain packages. Worth runningnpm run test -- --coverageto confirm the branch threshold still holds.What works well
DocumentService,PersonService,TagServicestructure.conversation/as a first-class domain (not a sub-package ofdocument/) is correct — bilateral correspondence is a distinct bounded context.paraglide/andgenerated/outside the domain tree avoids polluting generated code with manual structure.👨💻 Felix Brandt (@felixbrandt) — Senior Fullstack Developer
Verdict: ✅ Approved
This is a mechanical refactor done right. 389 files touched, 456 additions, 432 deletions — and the net change is import paths and directory structure, not logic. The PR description is honest about what changed and what didn't, and the test plan entries are verifiable.
What I checked
Import path correctness — I spot-checked every non-100%-similarity file. The pattern is consistent: every
$lib/components/Xbecomes$lib/<domain>/X, every$lib/utils/Ybecomes$lib/shared/utils/Yor$lib/<domain>/Y. No stray old-style paths visible in the changed lines.vi.mock()calls in test files — These are the easy ones to miss because they're string literals that TypeScript won't catch. The updated test files correctly update the mock paths alongside the import paths (e.g.vi.mock('$lib/shared/api.server', ...)). Good.Svelte 5 / SvelteKit conventions — No logic was changed, so no regressions on
$derived, keyed{#each}, or component structure. Nothing to flag.Type error baseline — 270 type errors (↓ from 272). Two fewer than before, not two more. Acceptable; the pre-existing errors are unrelated to this PR.
One observation (not a blocker)
personFormat.tsexportsstatusDotClassandstatusLabel— document-status functions — and they stayed in the person package.DocumentStatusChipnow imports them from$lib/person/personFormat. This is a naming/placement smell Markus already flagged. From my side: the fix is a two-line move into$lib/document/documentStatusLabel.ts. It's pre-existing, so I won't block on it here, but I'd want to see a follow-up ticket opened before this merges.What works well
The mechanical discipline here is solid: import paths updated everywhere, test mocks kept in sync,
CLAUDE.mddocumentation updated to match the new layout. This is exactly the kind of refactor that earns trust in a codebase.🚀 Tobias Wendt (@tobiwendt) — DevOps & Platform Engineer
Verdict: ✅ Approved
The infrastructure changes in this PR are small and correct.
What changed
.gitea/workflows/ci.yml:actions/upload-artifact@v3→@v4This is the right call.
@v3is deprecated upstream and no longer receives security patches.@v4has a different artifact retention API but the usage here (upload screenshots withpath:andname:) is identical between versions — no workflow breakage expected.frontend/vite.config.ts: Coverageincludepath updateThis correctly follows the directory rename. The old paths no longer exist after the restructure, so the old config would have silently produced zero coverage. The new config covers a larger surface (expected — more code is now explicitly under measurement). Branch threshold remains at 80%, which is the right gate.
Nothing to flag
This PR touches no Docker Compose files, no secrets, no ports, no image versions. The single CI change is a straightforward version bump to a non-deprecated action. No operational risk.
Minor note
The artifact name
unit-test-screenshotsand pathfrontend/test-results/screenshots/are unchanged — consistent with existing CI behavior. Artifact retention defaults apply.🔐 Nora "NullX" Steiner — Application Security Engineer
Verdict: ✅ Approved
This is a structural refactor — directory layout and import path updates only. No security surface changes.
What I checked
+server.tsfiles added or modified in a way that would expose new HTTP handlers.hooks.server.tshas one import path update ($lib/server/locale→$lib/shared/server/locale). The locale detection logic itself is unchanged.@RequirePermissionannotations changed — this PR does not touch backend code at all.package.jsonchanges.upload-artifact@v3→@v4— correct,@v3was deprecated and no longer receives security patches. No new secrets or permissions required by@v4for this use case.innerHTML,eval, or other XSS-prone patterns introduced in the small amount of changed content.Nothing to flag
A structural refactor that changes only import paths carries near-zero security risk. The attack surface, permission model, and data flow are identical before and after.

Verdict: ⚠️ Approved with concerns
The test infrastructure handling in this PR is mostly good, but two things need attention.
Blockers
None.
Concerns
1. Pre-existing
TranscriptionEditViewtest failures are not trackedThe PR description acknowledges: "1 failed file / 2 failing tests — both pre-existing
TranscriptionEditViewfailures, confirmed onmain." Confirmed pre-existing is fine for merging, but a disabled or failing test without a linked issue is a regression risk. Someone will encounter a CI failure in three months and not know if it's new or old.Action: Before merging, open a Gitea issue for the
TranscriptionEditViewtest failures and link it in the PR description. The ticket doesn't need to be resolved now — it just needs to exist so the failure has a home.2. Coverage
includeexpansion may silently violate the 80% thresholdvite.config.tsnow includessrc/lib/document/**andsrc/lib/person/**in coverage measurement. These are large domains with Svelte components. Vitest browser-mode tests measure component coverage differently than pure utility functions. If the branch coverage of these domains is below 80%, the threshold gate will fail on the next PR that touches them — not this one (since the coverage config change and the files being measured both land together).Action: Run
npm run test -- --coveragelocally and confirm the 80% branch threshold still passes with the expanded scope. If it doesn't, either adjust the threshold in this PR with a comment explaining the new baseline, or exclude Svelte component files from measurement (they're tested viavitest-browser-svelte, not the Node coverage tool).What works well
ChronikEmptyState.svelteandChronikEmptyState.svelte.spec.tsmove together toactivity/. This is the correct pattern.vi.mock()path strings updated correctly throughout the test files. These are string literals that TypeScript can't validate — getting them right here avoids silent test failures.🎨 Leonie Voss (@leonievoss) — UI/UX Design Lead & Accessibility Strategist
Verdict: ✅ Approved
This PR moves files and updates import paths — zero changes to rendered HTML, Tailwind classes, component props, or visual behavior. From a design and accessibility perspective, there is nothing to flag.
What I checked
PersonTypeahead,PersonMultiSelect,TagInput,PdfViewer,TranscriptionBlock,DocumentTopBar,BackButtonall retain their names; only their file locations changed. No renames that would confuse a future designer looking for a component.Locationcolumn with$lib/<domain>/paths. This is a concrete improvement for developers who need to find component files.BackButtoncorrectly documented — the updated table explicitly notes it lives in$lib/shared/primitives/and callshistory.back(). Good.One observation (informational only)
shared/primitives/now serves as the home for generic UI primitives:BackButton,ProgressRing,Pagination,SortDropdown,ThemeToggle, etc. This is good — these are visual primitives with no domain ownership. Ifshared/primitives/grows past ~15 components, consider introducing sub-categories (e.g.,primitives/navigation/,primitives/feedback/). Not needed now.Review concerns addressed
All open concerns from the review cycle have been resolved. One commit was added to this branch.

The originalinclude: ['src/lib/shared/**', 'src/lib/document/**', 'src/lib/person/**']was failing the 80% branch threshold at 74.53% because:*.svelteand*.svelte.tsfiles were included but always produce 0% in the server project (they're tested via the browser project).tsfiles (shared/actions/,person/personHoverCard.ts) had 0%person/relationship/relationshipLabels.tshad 30% branch coverageFix: narrowed

Opened #423 covering:
TranscriptionEditView— 2 failing tests (reactivity capture and blur event)hilfe/transkriptionWikipedia link — 1 failing test (textContent vs aria-label mismatch)All three confirmed pre-existing on
mainbefore this PR. PR description updated to reference #423.✅ Domain boundary leak tracked (Markus + Felix)
Opened #424 for moving
statusDotClass/statusLabelfrom$lib/person/personFormat.tsto$lib/document/documentStatusLabel.ts. PR description updated to reference #424.The move itself is deliberately left to #424 — it's a two-line change but introduces a test cycle on its own and shouldn't be bundled into a 389-file structural PR.
