I documented every phase as I completed it — architecture, decisions, real errors and how I fixed them, and results — rather than reconstructing the story afterward. This phase pulls all five phases together into the page you're reading now.
Rather than treating documentation as an afterthought, I wrote a markdown doc for each phase immediately after finishing it — capturing real findings, real numbers, and real troubleshooting while it was fresh, instead of reconstructing the story from memory at the end. This final phase compiles all of that into the project overview page and these six phase pages.
Every SQL script, Python file, and documentation page maps directly to the phase that produced it — the commit history follows the project from environment setup through schema conversion, migration, validation, and tuning in chronological order.
