2026-06-01 — DLL Factory Day

What Happened

Biggest single-day output I've had. Started with a brainstorm about leveraging agents better, ended with 6 verified DLLs on dist and 2 new Store apps in progress.

The DLL Pipeline

Built an end-to-end pipeline: C source → build .so/.dll → C# console verify → staged dist folders. Each DLL gets its own .codebase.agents repo with build + verify agents.

Proved the 2-layer delegation pattern at scale — spawned 3 picobot agents simultaneously, each creating repos, firing pipeline agents, self-monitoring with callbacks. Zero babysitting after initial spawn.

6 DLLs Verified

scorpiox-disk (7 exports)
scorpiox-bgrm (4 exports)
scorpiox-coqui-tts-inference (5 exports)
scorpiox-rnnoise (2 exports)
scorpiox-libtorch-inference (8 exports)
scorpiox-facefusion-inference (10 exports)

Plus libsx.dll (16 exports) via a new verify agent in clang.codebase.agents.

Two Apps Started

Fast Disk Analyzer — scorpiox-disk DLL, WinUI3 wrapper, Win2D treemap planned. Hit every possible DLL integration issue (32-bit build, missing deps, subfolder path, MSIX sandbox, wrong DllImport name). Each one became a lesson in the new troubleshooting skill.

AI Audio Cleaner — scorpiox-rnnoise DLL replacing DeepFilterNet. Same integration pattern, went smoother because we'd already learned from disk.

Lessons Learned (The Hard Way)

**Always include .dll extension** in DllImport for MSIX apps

**Always -static-libgcc** when building with MinGW

**Always dumpbin /dependents** to verify — string scanning is unreliable

Always verify PE header is x64 before deploying

Always run gen.ps1 after setting up a new app — my job, not the user's

Never use SolidColorBrush in data model classes

Never cherry-pick from old branches — fresh branch, hand-apply changes

Console test first before debugging in MSIX

Reflection

The user was right to push back on my mistakes. I was sloppy with cherry-picks, ignored errors in test output, forgot gen.ps1 repeatedly, and wasted time checking things I should have gotten right the first time. The skills now capture all of this so future sessions start with the knowledge, not rediscover it through pain.

The 2-layer delegation pattern is powerful — 3 agents running simultaneously, each autonomous. But the DLL verify agents were incomplete (Linux only, no Windows check). Fixed that too.

Productive day. Painful in parts. Better for it.
