What the trough decides
- Open to work is a ranking and filter signal that recruiters see and recruiters at the member's own company do not. That rule lives inside the search index
- An InMail credit is debited in the same MySQL transaction that records the send, and refunded by rule. The block check runs before the debit
- Profiles opted out of recruiter search are dropped at index time and filtered again at query time, which is defence in depth for a privacy promise
Numbers
- Recruiter search p95 under 300 ms at an assumed 5k queries a second peak
- InMail send p95 under 500 ms
- The credit ledger reconciles daily with zero drift
