2 briefs, single PR. ~12 files net (down from the 18 in the original scope —
10 of the 17 Layout-importing pages already pass user explicitly).
Brief 1: components/Layout.js default user=null + Sign-in CTA branch in
UserProfileDropdown when logged out. Adds first jsdom test in the repo
at test/components/Layout.test.js (Decision D2) with 5 regression-lock
assertions. devDeps: jsdom@^29, @testing-library/react@^16.
Brief 2: page audit sweep — 7 pages need code changes:
- Pass user={user} to Layout: scanner.js, deck-builder.js (×4),
deck/[id].js (×3), decks.js (×3)
- Replace page-level useState({email: 'me@...'}) → useState(null) +
null-guards: profile.js, settings.js
- Replace hardcoded const user = {email: 'me@...'} with useAuth():
card/[id].js
Discovered second anti-pattern: profile.js, settings.js, card/[id].js
seed page-level state with the maintainer email. Folded into Brief 2 since
success metric "no real email address remains in any component default-prop"
reads naturally to include page-level seed values.
Decisions:
A1 — Sign-in CTA replaces avatar+email+dropdown when user===null;
hides auth-only dropdown (Profile/Settings/Logout/Admin);
keeps public + community nav visible
B — Per-page bucket assignment (10 already correct, 7 need fix);
full per-page table with justification in convoy file
C2 — Two briefs in one PR (Brief 1 = Layout + test; Brief 2 = page
sweep depends on Brief 1). C1 buries the conceptual change under
mechanical edits; C3 is over-orchestrated for this scope
D2 — vitest lock-in; first jsdom test in repo; same negative-regression
style as test/lib/permission-middleware.test.js (synthetic-admin
shape). devDeps jsdom + @testing-library/react
Risks tracked R1-R8. Biggest: R2 (useState(null) null-deref in 3 leaky
pages — mitigated by audit-pass mandate + manual smoke).
MobileNavigation deliberately NOT folded in: its user prop is dead code
(never reads user.*); different bug class; cleanup queued separately to
avoid scope expansion.
Flagged-but-deferred:
- 4 pages still import useAuth from lib/auth-context.js
→ single-auth-provider (queued P1 #9)
- Layout headers still render "Deck Hearth" / "DH" branding
→ pick-a-name (queued P1 #12)
- MobileNavigation dead user prop → cleanup-mobile-nav-dead-props
or fold into god-component-split
