Critical fixes:
- sanitizeLoadedHitStats/VisitorStats: restore full state shape so a
snapshot restore no longer crashes hit-counting middleware (missing
byPathReal, byPathBot, byDayReal, byDayBot, botReasons, ipHashIndex)
- /questions/share/🆔 read state.questions only, not draft questions
- inbound-email: validate date with Number.isFinite before toISOString
- study-reminders: wrap each send in try/catch so one failure doesn't
block remaining users; persist sent-markers after each success
Security:
- getClientIp: use req.ip (trust-proxy-resolved) instead of raw
x-forwarded-for header to prevent IP spoofing
- env-snapshot.env: delete immediately after backup tar stream ends
so secrets don't linger on disk between exports
Correctness / UX:
- contact form: email failures no longer 500 the user after the
submission is already saved; log and fall through instead
- study-account profile: cap data URI avatar at 6 MB
- admin enrollment PATCH: validate slug against study catalog
- signup: return 503 at MAX_STUDY_USERS instead of silently dropping
oldest accounts
Memory leaks:
- contactHits, downloadHits Maps: prune stale entries at 5000 entries
- resendEmailSubmissionIndex: trim to 2000 entries (oldest first)
