Closes the page-side half of P0 #7 from .convoys/ship-readiness.md.
Brief 1 (commit ddf8fd2) handled the Layout-side fix.
Per the architect's per-page bucket table (Decision B in
.convoys/fix-layout-default-user.md), 7 pages needed code changes;
the other 10 of 17 Layout-importing pages already pass `user` correctly.
Pass user={user} to Layout (4 pages, 11 call sites):
- pages/scanner.js (1 call)
- pages/decks.js (3 calls)
- pages/deck-builder.js (4 calls)
- pages/deck/[id].js (3 calls)
(All four still import useAuth from lib/auth-context.js — that's
intentional and stays as-is until the single-auth-provider convoy
collapses the three parallel auth surfaces.)
Replace leaky page-level seed values with useState(null) + null guards
(2 pages, R2 mitigation):
- pages/profile.js: useState({email: 'me@...', role: 'user', ...})
→ useState(null) + ?. on every sync user.* read
+ early-return guards in getDisplayName/getInitials
+ conditional render around the "Member since" block
so formatDate(undefined) never runs
- pages/settings.js: same pattern (single user.email reader guarded)
Replace hardcoded const with useAuth from lib/use-auth.js (1 page):
- pages/card/[id].js: const user = {email: 'me@...'}
→ const { user } = useAuth() (called unconditionally
at the top of the component; rules-of-hooks safe)
Verification:
- grep 'me@randallstillwell.com' pages/ → 0 hits
- 21/21 vitest tests pass (16 pre-existing + 5 from Brief 1)
- npm run lint matches baseline (128 problems pre, 128 post; verified
via git stash before/after)
- Manual static read-through of every diff; ReadLints clean on the 7
files
- Dev-server smoke: /cards anonymous returned HTTP 200 with 0
'me@randallstillwell' matches before the user's shared dev server
became unresponsive mid-session (same dev-server-shared-by-user
constraint flagged in Brief 1); interactive logged-in smoke is
parent/operator gated
Flagged-but-deferred (untouched per scope):
- 4 pages still import useAuth from lib/auth-context.js
→ single-auth-provider (queued P1 #9)
- components/MobileNavigation.js still receives dead user prop
→ cleanup-mobile-nav-dead-props (or fold into god-component-split)
addresses: P0 #7 from .convoys/ship-readiness.md (last P0 ship-blocker)
