Read its date before describing an item as current. - [Knowledge](https://aserdargun.com/memory/): Authored public research notes and decisions with sources. - [Portfolio registry](https://aserdargun.com/portfolio.json): Structured public application identities and relationships. - [Application schema](https://aserdargun.com/schemas/aserdargun-app.schema.json): Public manifest contract. - [Türkçe](https://aserdargun.com/tr/): Turkish overview; /tr/about/, /tr/journey/, /tr/applications/, /tr/now/, and /tr/memory/ provide matching editions. ## Reading the evidence Research cutoffs, verification dates, release dates, and release SHAs describe different events. A missing value means unknown. Planned directions are not completed products. Diagram relationships describe how topics inform each other; they do not establish runtime integration. Private systems are linked as separate applications; their private records are not part of this public source.
