May 22
I outlined unit, integration, API, smoke, and E2E tests for a mono project. I also noted an OnlyFans API sandbox and backend refactor. Local development needed
May 20
I compared OnlyFans API wrappers with the API list from the cai project, putting both into OpenAPI YAML. I looked at OnlyFans API Docs, OFMAPI, and UltimaScrape
Apr 14
Payment progress was 4/10. For AI coding, I noted Gstack and Pencil, and the problem of reviews that did not converge. I also noted a Coding Copilot idea.

I wanted to practice writing and meditation more deliberately.

The Q2 goal was three agent-powered workflows in production per team. The Sorin Agentic Task still needed confirmation. For Melon, I noted questions about cross

At the weekly meeting, we discussed replacing Nginx Ingress with the Istio Gateway API. SigNoz was integrated, but its daemon deployment still had a problem. Ku

The architecture cleanup was about 60% done. I was removing temporary components and unused modules to make the project easier to maintain. Keycloak IAM integra

Last week, I removed about 80% to 90% of the Go orchestration layer. I also improved the service update flow and got the core Keycloak integration working. Next
Dec 05
I saved before and after snapshots of the application and orchestration layers. Before: Before After: After | Layer | Before | After | | --- | ---: | ---: | | A

I was working on removing the Go orchestration layer from Hive. I wrote "1.8 Development Done" next to it, without more detail. Related note: 2025-11-27.
Nov 27
Hive I was removing the Go orchestration layer. My notes marked the K8s, Tekton, and Knative clients under Fabric8 SDK as checked. The Harbor API under OpenAPI

x402 Paywall I wanted to decide whether to keep working on x402 Paywall and write down why. My architecture ideas were a Cloudflare Worker that adds an X-Paywal
