Then we fix it.\n\nxounce only reports vulnerabilities it can actually exploit — each with a replayable proof-of-concept and the pull request that fixes it.\n\n**What it is:** Application security / vulnerability management — a continuous validated vulnerability pipeline (CVVP).\n**Status:** Pre-launch. Onboarding a small group of design partners (read-only, one repo, free while we build). Applying to Y Combinator, 2026.\n**The name:** The name comes from 'bounce': xounce bounces what shouldn't get through back out — malicious code, malicious requests, and technical debt.\n\n## The proof gate\n1. Detected — scan everything: SAST, SCA, secrets, IaC, DAST.\n2. Reachable — the vulnerable function or flow is actually used in your code (call-graph over the AST), not just the package installed.\n3. Exposed — that path is reachable from the public internet: real attack surface, not theoretical.\n4. Confirmed — AI probes each candidate and lands a working exploit. No proof-of-concept, no report. Each survivor ships with a replayable PoC and, where the fix is mechanical, an open pull request.\n\n## Capabilities\n- Proof-gated scanning across SAST, SCA, secrets, IaC and DAST — reports only what it can prove; everything else is retained for audit, off the main view.\n- Auto-fix pull requests: bumps the package, regenerates the lockfile, with the CVE details and the exploit proof in the PR body.
