test: add ~500 tests across web, utils, api, import, ai, db, email, auth (#3038)

* test(web): add tests for zustand stores and pure helpers

Cover stores and pure helpers across the builder/dashboard/command-palette
surfaces that previously had 0% coverage:

- command-palette store (open/close, page stack, search clearing, goBack)
- builder assistant-store
- builder sidebar store + parseBuilderLayoutCookie / mapPanelLayoutToBuilderLayout
- builder section store (collapse, toggle, toggleAll)
- builder preview page-layout toggle
- dashboard resume-thumbnail render-size math + cache key
- MCP tool name + annotations invariants

* test(web): cover MCP helpers and template metadata

Add tests for previously 0%-coverage MCP and dialog helpers:

- buildMcpServerCard: server-info, tool catalog vs MCP_TOOL_NAME, prompts,
  resource templates, configuration schema, auth schemes
- registerPrompts (build/improve/review): registration, args schema, resource
  context with interpolated resume id, read-only / no-fabrication directives
- registerResources (resume://{id}, resume://_meta/schema): handler reads via
  oRPC client, error on missing id, schema returns valid JSON
- templates metadata: ids match display names, valid sidebar positions,
  unique image URLs, every entry has tags + description

* test(web): cover sidebar section helpers and layout screens

Add tests for previously near-0%-coverage modules:

- libs/resume/section: getSectionTitle / getSectionIcon return distinct,
  exhaustive results for every sidebar section + cover-letter; icon props
  forwarding; left/right sidebar collections do not overlap.
- layout/loading-screen: spinner + text render.
- layout/error-screen: error message surfaces, Refresh button triggers reset.
- layout/breakpoint-indicator: default + each corner positioning, all
  breakpoint labels rendered, print-hidden class applied.

* test(web): cover preview canvas math and font-weight defaults

Add tests for pure helpers that previously had no direct coverage:

- typography/getNextWeights: prefers 400 + 600 when both are available,
  returns null for unknown families, never produces duplicates, bounded
  to two weights from the 100..900 set.
- preview.shared/normalizeResumePreviewProps: documented defaults +
  pass-through.
- preview.shared/getScaledPreviewPageSize: scaling identity at 1, and
  fractional scaling.
- preview.shared/getPreviewCanvasScale: respects 4x desired scale for
  small pages, honors high devicePixelRatio, clamps to the 16M-pixel
  canvas budget for large pages.

* test(utils): cover DOCX section renderers and html-to-paragraphs

@reactive-resume/utils/resume/docx was previously at ~2.84% statement
coverage despite being load-bearing for the resume DOCX export.

- section-renderers: empty-string / hidden-section / hidden-item branches
  for renderSummary, renderBuiltInSection, and renderCustomSection;
  cover-letter and summary custom-section dispatch; unknown-type fallback;
  setRenderConfig idempotency.
- html-to-docx: whitespace-only short-circuit, multiple top-level blocks,
  h1..h6 paragraph mapping, inline style and link rendering, custom
  font/size/color/linkColor config, ignored script/comment nodes.

* test: cover DOCX builder smoke paths and reactive-resume JSON importer

- utils/resume/docx/builder: buildDocument runs end-to-end against the
  default and sample resume data, both page formats, full-width and
  sidebar layouts, and gracefully degrades with unparseable color or
  empty font family inputs.
- import/reactive-resume-json: ReactiveResumeJSONImporter validates
  malformed JSON, recovers missing built-in sections by appending them
  to page 1 without reordering, and preserves layouts that already
  contain every built-in section.

* test(import): cover JSONResumeImporter parse/convert

JSONResumeImporter (450 lines) was previously at 0% coverage. Add tests
for the public surface:

- Invalid JSON / invalid-shape errors are surfaced.
- basics, summary, picture, education, projects, skills, profiles all
  map to the corresponding ResumeData sections.
- Empty work/education entries (missing key field) are filtered out.
- Highlights become HTML list items in the description field.
- Skill level parsing flows through utils/level.parseLevel.
- formatLocation joins city, region, countryCode with commas.

* test(web): cover query client serializer and home-page animations

- libs/query/client: getQueryClient returns a fresh QueryClient,
  queryKeyHashFn produces stable JSON envelopes for matching keys
  (and distinct strings for different keys), dehydrate/hydrate
  round-trip Date values via the oRPC serializer.
- components/animation/spotlight: overlay container is
  pointer-events-none, both beam groups render, custom
  width/height/translateY/gradient props flow into inline styles.
- components/animation/comet-card: children mount inside the
  perspective wrapper, custom className is merged with the 3D
  baseline classes, glare overlay renders, mouse move/leave
  handlers do not throw.

* test(web): cover Copyright footer

Verify the footer's MIT license link, Amruth Pillai attribution,
external-tab targets, embedded app version (via __APP_VERSION__ stub),
and custom className merging — previously at 0% coverage.

* test(api): cover flags, auth providers, and resume-access cookies

Unlock @reactive-resume/api by mocking @reactive-resume/env/server and
@tanstack/react-start/server. Previously the only services tested were
the standalone AI test and resume-access-policy.

- services/flags: flagsService.getFlags reads disableSignups/disableEmailAuth
  from env (no stale cache).
- services/auth: providers.list always exposes credential + passkey, and
  only adds Google/GitHub/LinkedIn/custom when both id and secret are set;
  custom provider uses OAUTH_PROVIDER_NAME with a 'Custom OAuth' fallback.
- helpers/resume-access: hasResumeAccess validates against signed cookies
  with constant-time comparison; grantResumeAccess writes a 10-minute
  httpOnly cookie with the secure flag matching APP_URL's https-ness.

* test: cover statistics service and email transport via env mocks

- api/services/statistics: github star count succeeds, retries on
  non-OK, falls back to last-known on fetch error / non-positive /
  non-numeric responses; user and resume counts roll up DB count.
- email/src/transport: returns silently with no text/html, logs when
  SMTP is not configured, dispatches via nodemailer with the env
  config when fully wired, renders react elements to html + text
  bodies, swallows transport errors instead of crashing.

* test(api): cover resume-events publish + subscribe

- publishResumeUpdated issues pg_notify with channel and serialized
  event payload.
- subscribeResumeUpdated yields events whose resumeId+userId match
  the subscription, filters out other resumes/users, ignores
  malformed JSON and notifications on other channels, calls
  LISTEN/UNLISTEN and releases the client, and terminates
  immediately if the abort signal fires before iteration starts.

* test(api): cover oRPC auth resolution

resolveUserFromRequestHeaders is the single point where every oRPC
procedure picks up the authenticated user. Test the priority chain:

- x-api-key wins when present and valid
- on invalid api key, falls back to session via auth.api.getSession
- Bearer JWT in Authorization header is verified via verifyOAuthToken
- invalid Bearer falls back to session
- Authorization scheme other than Bearer is ignored entirely
- thrown errors from token verification are logged and swallowed
  (caller still tries session)
- returns null when no auth method succeeds

* test(api): cover storage helpers

inferContentType, isImageFile, processImageForUpload were 0%
coverage despite being on the picture upload path.

- inferContentType maps known image and pdf extensions, is
  case-insensitive, ignores path depth, and falls back to
  application/octet-stream for unknown.
- isImageFile allows only the upload allowlist (gif/png/jpeg/webp)
  and rejects image/svg+xml, application/pdf, and empty strings.
- processImageForUpload short-circuits to the original bytes when
  FLAG_DISABLE_IMAGE_PROCESSING is true, otherwise pipes through
  sharp and returns image/jpeg.

* test(import): broaden v4 importer section-mapping coverage

The existing v4 importer test focused on a single bug (description-only
custom items) and the skill/language level scaling. This new test
exercises the bulk of the v4 → v5 transformation path:

- basics, picture (with border), summary, customFields
- every section's filter-by-required-field invariant (awards needs
  title, certifications needs name, education needs institution,
  experience needs company, volunteer needs organization, etc.)
- experience / education / awards / certifications / references field
  renames between schemas
- language and skill level scaling (v4 0..10 → v5 0..5)

Brings reactive-resume-v4-json from ~66% statement coverage to a
materially higher figure (the bulk of the 410-line transformer body).

* test: cover buildDocx entry and AI configuration store

- utils/resume/docx/index: buildDocx returns a non-empty Blob for both
  default and populated resumes (previously 0% coverage despite being
  the public DOCX entry point).
- ai/store: useAIStore preserves verification status across no-op
  updates, but resets testStatus + enabled whenever provider, model,
  apiKey, or baseURL changes; canEnable is gated to testStatus=success;
  setEnabled(true) is refused unless verified; reset clears every
  field. Brings @reactive-resume/ai from ~72% to materially higher
  coverage.

* test(db): cover resume schema definitions

packages/db was previously at 0% coverage. Smoke-test the public
resume / resume_statistics / resume_analysis tables:

- getTableName matches the SQL identifier used by migrations
- expected columns are present on each table
- defaultResumeData wiring on the data column resolves to a valid
  shape

These are structural assertions that catch accidental renames /
removals without needing a live database connection.

* test(db): cover auth schema tables and relations export

- src/schema/auth: table-driven test for each of the 12 auth tables
  asserting SQL name and presence of the key columns (user/session/
  account/verification/two_factor/passkey/apikey/jwks/oauth_*).
- src/relations: smoke test confirming the relations export is defined.

Brings @reactive-resume/db from 0% to materially higher coverage.

* test(auth): cover getSession isomorphic helper

@reactive-resume/auth was previously at 0% coverage. functions.ts
is the server entry point that other packages call. Mock the auth
config + tanstack/react-start to verify:

- getSession forwards getRequestHeaders() to auth.api.getSession
- returns null when better-auth returns null

* test(web): cover BuilderSidebarEdge

Small presentational component on the builder layout — assert children
mount, left/right positioning class branches, and the sm:flex
mobile-hide behavior.

* test(web): cover section-title-locale resolver cache and hook

The section-title-locale module wraps createSectionTitleResolver with
a per-locale async cache and a React hook for consumers in the
builder. Cover:

- createSectionTitleResolverForLocale returns a usable resolver
- repeated calls for the same locale share a cached promise
- unknown locales fall back through resolveLocale
- useSectionTitleResolver returns null while loading and when no
  locale is passed
- the hook resolves to a function once the async loader settles

* test(web): cover BaseCommandGroup page-stack gating

BaseCommandGroup conditionally renders based on the top of the
command-palette page stack. Tests cover:

- root group renders when no sub-page is active
- root group hides when a sub-page is on top
- sub-page group renders only when its page matches
- mismatched sub-page leaves the group hidden

* test(web): cover ThemeProvider context

- useTheme outside ThemeProvider throws the documented error
- useTheme inside ThemeProvider returns the theme + setTheme +
  toggleTheme helpers

* test(web): cover ConfirmDialogProvider + useConfirm hook

- useConfirm outside provider throws the documented error
- confirm returns a pending promise
- promise resolves false when the Cancel button is clicked
- promise resolves true when the Confirm button is clicked
- works with custom confirmText label

apps/web has its own copy of this hook distinct from
packages/ui (mirrors the existing UI-package tests).

* test(web): cover PromptDialogProvider + usePrompt hook

- usePrompt outside provider throws the documented error
- returns a function when wrapped
- Cancel click resolves the promise to null
- Confirm click resolves to the current input value
- defaultValue option seeds the initial input value

* test(web): cover DashboardHeader

Small presentational header used across dashboard routes — title h1,
icon rendering, className merge, mobile sidebar trigger present and
hidden on md+.

* test(web): cover Create/Import resume cards

Both cards on the resumes dashboard wire a click handler to open
the appropriate dialog via the dialog store:

- CreateResumeCard opens resume.create
- ImportResumeCard opens resume.import

Also asserts the i18n copy strings (icons aside, the cards are
otherwise structural).

* test(web): cover command-palette language sub-page

LanguageCommandPage is a BaseCommandGroup gated on page='language'.
Tests assert:

- it is hidden when 'language' is not the top of the page stack
- when active, it renders a CommandItem per localeMap entry
- documented locale codes (en-US, de-DE, ja-JP) appear

* test(web): cover command-palette theme + preferences sub-pages

- ThemeCommandPage: hidden when 'theme' is not on top, renders Light
  and Dark options when active
- PreferencesCommandGroup: root group renders both Change theme to...
  and Change language to... items; clicking each pushes the
  corresponding page onto the command-palette stack

* test(ai): cover executePatchResume tool

- patchResumeInputSchema rejects empty operations and unknown op
  values; accepts valid replace/add/remove
- executePatchResume returns the applied operations on success
- executePatchResume throws when an operation targets an invalid path
  (passes through the underlying applyResumePatches validation)
- multi-op patches against top-level fields succeed end-to-end

* test(ai): cover sanitize edge branches

Hit the previously-uncovered branches in sanitize.ts:

- numeric 1 coerces to true
- '1' / '0' string shorthand coerces to true/false
- missing item.hidden gets salvaged to false
- empty input causes a non-Zod throw (caught + rethrown with generic message)

* test(ai): cover patch-proposal preview + normalize edge cases

- remove operations surface before-value with after=undefined
- buildResumePatchProposalPreview labels metadata/page paths sanely
- normalizeResumePatchProposals stamps every proposal with baseUpdatedAt
- normalizeResumePatchProposals preserves input order

* test(web): cover getLocaleOptions helper

Locale combobox surface — verify the option list mirrors localeMap
shape, uses locale codes as values, populates label + keywords with
the translated display name, and produces unique values.

* test(web): cover LevelTypeCombobox option mapping

LevelTypeCombobox maps levelDesignSchema.shape.type.options through
the internal getLevelTypeName labeler. Assert all 7 level types are
exposed and that each produces a non-empty label.

* test(web): cover ThemeToggleButton fallback paths

- aria-label flips between 'Switch to light theme' and 'Switch to
  dark theme' based on current theme
- clicking when document.startViewTransition is unavailable
  short-circuits to toggleTheme directly
- prefers-reduced-motion forces the direct toggle path even when
  the view-transition API is available

* test(web): cover NotFoundScreen

Mock the TanStack Router Link so the screen renders standalone, then
assert: documented error heading, routeId is surfaced verbatim, and
the Go Back link points to '..' (parent route).

* test(web): cover InformationSectionBuilder

Stub SectionBase so the donation/info section renders standalone.
Assert: donation prompt copy, OpenCollective CTA link, all 5
external resource links present, and external links target _blank
with rel=noopener.

* test(web): cover NotesSectionBuilder

Mock SectionBase, RichInput, and the resume-draft hooks so the
notes section renders in isolation. Assert: privacy hint copy
renders, RichInput is seeded with metadata.notes, and onChange
proxies through updateResumeData with a draft recipe that mutates
metadata.notes.

* test(web): cover TemplateSectionBuilder

Stub SectionBase and useCurrentResume so the right-sidebar template
section renders standalone. Asserts: current template name in the
heading, template tags rendered as badges, preview image points to
the catalog asset, and clicking the preview opens the
resume.template.gallery dialog.

* test(web): cover ColorPicker preset selection and trigger override

Mock the heavy @uiw/react-color-colorful dependency. Test:

- the trigger swatch reflects the controlled value
- clicking a preset color invokes onChange with an rgba() string
- a custom trigger replaces the default swatch when provided

* test(web): cover ExportSectionBuilder

Mock the heavy export pipelines (buildDocx, createResumePdfBlob,
downloadWithAnchor) and the resume-draft hook to test:

- JSON button packages resume.data as application/json and triggers
  download with the {name}.json filename
- DOCX button awaits buildDocx and downloads .docx
- PDF button awaits createResumePdfBlob and downloads .pdf

* test(web): cover ProfilesSectionBuilder

Stub the resume-draft hooks, SectionBase, SectionItem, and
SectionAddItemButton so the profiles section renders standalone:

- one SectionItem per profile with network as title and username as
  subtitle
- 'Add a new profile' affordance present
- when items.length > 0, the wrapper uses a solid border (not dashed)

* test(web): cover SkillsSectionBuilder

Mirror the profiles test for the skills section — verifies one
SectionItem per skill (name → title, proficiency → subtitle) and
the Add a new skill affordance.

* test(web): bulk-cover 7 left-sidebar section builders

Single test file covers awards, certifications, interests, languages,
publications, references, and volunteer builders. For each:

- one SectionItem rendered with the documented field → title/subtitle
  mapping
  - awards: title → awarder
  - certifications: title → 'issuer • date'
  - interests: name → (no subtitle)
  - languages: language → fluency
  - publications: title → publisher
  - references: name → (no subtitle)
  - volunteer: organization → location
- the 'Add a new {kind}' affordance with the matching copy

Mocks SectionBase, SectionItem, SectionAddItemButton, and the
resume-draft hooks so each builder renders standalone.

* test(web): cover ProjectsSectionBuilder buildSubtitle

The projects section is the only left-sidebar builder with a
composite subtitle. Tests three branches of its inline
buildSubtitle helper:

- period + website.label → joined with ' • '
- period only → just the period
- empty period + whitespace-only website.label → returns undefined

* test(web): cover Education + Experience section builders

- Education: school → title, degree → subtitle, add-new affordance
- Experience: position → subtitle when set; falls back to '1 role' /
  'N roles' (lingui plural) when position empty and roles[] present;
  add-new affordance

* test(web): cover CountUp animated number renderer

- default aria attributes (aria-live=polite, aria-atomic=true)
- initial textContent seeds to 'from' (up) or 'to' (down) value
- separator option formats with grouping
- decimal places are preserved when from/to are fractional
- aria-hidden=true strips aria-live + aria-atomic
- custom className is applied to the rendered span

* test(web): cover TextMaskEffect SVG renderer

- supplied text renders in every visible <text> layer
- aria-hidden + aria-label forwarded onto the root svg
- mouse enter/move/leave handlers don't throw
- custom className merges into the svg's class attribute

* test(web): cover URLInput prefix handling

- displayed input strips the https:// prefix so users only edit the
  meaningful portion
- editing re-adds the prefix on the way back through onChange
- pre-prefixed input is preserved
- cleared input emits an empty url (no prefix forced)
- hideLabelButton=true removes the popover trigger; default keeps it

* test(web): cover GithubStarsButton

Mocks useQuery + the CountUp animation so the button renders
standalone. Asserts:

- anchor points at the project repo with rel=noopener + target=_blank
- aria-label is the no-count copy when star count is undefined
- CountUp renders only once the count loads
- aria-label includes the localized count once data arrives

* test(web): cover ui/Combobox trigger label rendering

The shared Combobox wraps base-ui's combobox primitives. Smoke-test
the trigger label resolution:

- placeholder shows when nothing is selected
- selected option's label renders in the trigger
- multi-select default values render all labels
- empty options array renders the placeholder without crashing

* test(web): cover IconPicker trigger rendering

Stub react-window's Grid so happy-dom can render the picker without
layout-measurement deps. Verify:

- trigger renders an <i class='ph-{value}'> for the current value
- changing value updates the trigger icon class
- the picker emits a trigger button

* test(web): cover ChipInput add/dedupe/description behaviors

- existing chips render as Badges
- Enter adds the typed value to the chip list
- comma also commits the typed value
- duplicate input is dropped (onChange not called with a longer list)
- empty / whitespace-only input is dropped
- hideDescription removes the keyboard hint <kbd>; default keeps it

* test(web): cover StatisticsSectionBuilder

Mock useQuery + useParams + section-base so the right-sidebar
statistics section renders standalone:

- returns null content while the query is loading
- shows the private-resume hint when isPublic=false
- shows views/downloads counters and labels when isPublic=true
- includes 'Last viewed' timestamp copy when lastViewedAt is set

* test(web): cover TemplateGalleryDialog selection flow

- title + intro copy render
- one tile per template (>= 14)
- currently-selected template tile carries the ring-highlight
- clicking a different tile triggers updateResumeData with a recipe
  that sets metadata.template to the chosen template id

* test(web): cover Prefooter home-page section

- community tagline heading renders
- community-thanks paragraph renders
- the decorative TextMaskEffect renders an svg

* test(web): cover home-page Footer

- Resources and Community headings render
- documented resource links (Documentation, Sponsorships, Source
  Code, Changelog) all appear in the rendered output
- documented community links (Report an issue, Translations,
  Subreddit, Discord) all appear
- social anchors point at GitHub, LinkedIn, and X (Twitter)
- Copyright sub-component surfaces the app version via __APP_VERSION__

* test(web): cover home-page Header navigation

Mock TanStack Router Link + child components so the header renders
standalone. Verify:

- homepage anchor (/ link) carries the documented aria-label
- dashboard anchor points to /dashboard
- ThemeToggleButton and GithubStarsButton both mount
- the <nav> landmark is labeled 'Main navigation'

* chore: fix linter warnings
