Theme: Invariants over assumptions Today wasn’t about building new features. It was about protecting the system from itself. 1️⃣ Position truth vs. Exchange truth The biggest lesson came from investigating Position 275. That contradiction forced me to confront something uncomfortable: A trading system is not allowed to “mostly” follow rules. It must follow them absolutely. I…

From “Net PnL” to Truthful Metrics Today was not about building something flashy. It was about removing subtle distortions from the system. And those are often the most important changes. 1. Fixed Parameter Binding Bug (Admin > Performance) I encountered a classic but dangerous issue: The root cause wasn’t MySQL. It was us. The exchange filter…

Today was a truth alignment day. Not feature-first. Not UI-first. But data-first. 1️⃣ Order Audit: Facing Missing Fee Reality I ran: At first glance, it looked fixed: But then the deeper truth surfaced: fee_usd was still null. Why? Because the DB snapshot had: Which means: That was the key realization. 💡 Lesson: If commission evidence is not…

Files Dev — 13/02 Theme of the day: Consistency is harder than correctness. Today was less about building new features and more about tightening the system’s internal truth. The kind of work that doesn’t look dramatic from the outside — but determines whether the system behaves like a professional product or a collection of scripts.…

Today was less about adding features and more about understanding the truth of the data. 1. EXIF Colour Space – From “It Works” to “Is It Correct?” I focused on the new EXIF backfill command: pa:exif:backfill-order {order_id} The command already: But something felt incomplete. When the command said: “skipped – already has colour space” I realized:…

Egis Dev – 12/02 Theme: Determinism, Hedge Mode Reality, and Admin Cohesion Today was one of those “systems maturity” days — less about building new features, more about confronting edge cases and tightening the contract between Egis and reality (Binance). 1️⃣ Hedge Mode Wasn’t “Just a Setting” The biggest battle today was the recurring Binance…

Today was not about adding flashy features. It was about tightening truth. 1. Strategy Report: From Snapshot to Lens I refined Admin > Insights > Strategy Report into something more analytical instead of decorative. This turned Strategy Report from a broad summary into a controlled lens. Now I can zoom into one symbol inside a signal scope instead…

Today was a small change on the surface, but an important one in terms of integration discipline. What I Did Today’s focus was on updating the border generation integration between PA (Staff App) and the Files API. This was intentionally a minimal, production-safe change. What I Learned 1. Integration changes should be surgical When working across systems…

Making Border Rendering Production-Ready Today was a transition day — from “it works in a test folder” to “it’s a real production feature.” 1. Stabilised Border Rendering (3mm & 5mm) I finalized both pipelines: Both now support: The key improvement: The system now fails loudly when it should. Earlier, the comparison falsely passed even when…

Today I focused on stabilizing and tightening the border rendering pipeline in the Files System, especially around correctness, determinism, and testability. What I did What I learned Overall, today was about turning a fuzzy, visual problem into a deterministic, testable system. The pipeline is now strict enough to expose what’s wrong, instead of hiding it.
