My Leboncoin ads sank in 3 days. I built a Manifest V3 extension that bumps them on a loop and scans prospect demands with weighted scoring. Code, DataDome, anti-scam.
36 resume iterations in two hours. Claude codes, I judge the render, dual ATS + recruiter scoring at every pass. What the iterative loop really changes.
You put everything in your CLAUDE.md because "more context = better". How I cut 52% of a production CLAUDE.md after a security audit, and why the agent codes better with less.
The pre-pentest audit in successive passes. How to verify findings before panicking, and how to select which probes become permanent regression tests.
The event-XOR-error invariant on command handlers. How to inform the caller of a business outcome without breaking the event/error separation, and why audit logging must be atomic.
tls.Config.VerifyConnection only runs at handshake. A client on keep-alive after revocation keeps serving. Double-gate pattern and CRL hot-reload with monotonic check.
A single TLS port serving three hosts via SNI with different ClientAuth levels. Plus the session cert binding pattern to block cookie replay attacks.
Synchronizer token server-side vs double-submit cookie: when the latter fails, why middleware wire-order matters, and how to handle JS non-form requests.
First N failures are silent, then exponential backoff capped at 15 min. Why the status code must never distinguish locked vs wrong creds, and how to reset properly.
