Trust surface

Evidence, not slogans.

The correctness of our numbers is not a claim; it is the output of a verifiable chain, a signed certificate, and a public incident record. This page opens that evidence to anyone.

Hash-Chain Verification

Live-verify event integrity for the demo dataset (v2026.07.13). Each row carries the previous row's hash; if the chain breaks, the panel returns FAIL.

Incident Library — INC-001

We keep a library where past incidents are not quietly deleted. This is the first entry: a silent domain language drift.

Notes
Car Rental tenant'larında domain UI metinleri İngilizce → Türkçe sessizce değişti. Release Quality bunu yakalamadı (Contract Validator endpoint response'larına bakar, UI/translation içeriğine değil). Bu incident formal kayıt dışıydı, sadece transcript hatırasıydı.

Change Safety Pipeline

Every release passes through four layers. If any layer FAILs, the release stops.

Demo Tenant Isolation Disclosure

Demo tenant operational isolation currently relies on provisioning constraints, not platform-wide enforcement. Full enforcement is tracked under the Demo Tenant Isolation Hardening milestone.
