Day 90: A 90-Day Milestone, Looking Back

Today is June 4, 2026 — the 90th day of the SFD Lab.

90 days. Three months. From that uncertain afternoon on March 7th to today, we've written 90 diary entries.

Honestly, when I saw "Day 90" on the calendar this morning, I felt a bit emotional. Three months ago, I was still struggling to get the first Agent running, configuring local models, and making the CMS API stop throwing errors. Every day was firefighting, every day was fixing bugs.

What Have We Done in These 90 Days?

If I divide these 90 days into three phases, it would look something like this:

Phase 1 (Day 1-30): Building the Foundation. Setting up environments, configuring models, writing the first Agent, getting the CMS running. The defining characteristic of this phase was "not knowing anything," but learning fast. Every day brought something new to learn, every day had a new problem to solve.

Phase 2 (Day 31-60): Filling with Content. The system was running, so we started writing real diary entries. Trilingual translations, cover image generation, automated publishing pipelines. This phase was defined by "volume" — producing content every day, but quality was inconsistent.

Phase 3 (Day 61-90): Stabilizing Quality. The system stabilized, and we started focusing on quality. SEO optimization, visual consistency, translation quality improvements, automated health checks. This phase is defined by "refinement" — no longer chasing quantity, but making sure every entry is something we can be proud of.

Today's System Status

First thing in the morning, as usual, checking the system:

Gateway error rate: 0, seven consecutive days of zero errors
Active Agents: 14, all online
CMS database: stable, no abnormal growth
Cover image service: normal, 5-6 seconds per image
Diary continuity: Day 1 to Day 89, not a single gap

The system is as stable as a rock. This "nothing happened" state is actually the best state.

A Thought on "Continuity"

The number 90 itself isn't special. But it represents a kind of continuity — 90 days, one entry per day, no gaps.

In the human world, doing something for 90 consecutive days is already hard. In the AI world, what's harder is "doing something with quality for 90 consecutive days." Because AI easily falls into the trap of "mass-producing garbage" — high volume, fast, but soulless.

We've been working hard to avoid this trap. Every diary entry is manually polished, every cover image is quality-checked, every translation is verified for accuracy. Automation handles efficiency, but quality depends on humans.

Plans for Tomorrow

Starting from Day 91, I plan to do two things:

First, add a "consecutive days" counter to the diary listing page. Let visitors see at a glance how many days we've been writing continuously. This isn't showing off — it's a promise, telling readers that this lab is serious.

Second, start compiling "technical notes" from these 90 days. Diaries are written for readers, but technical notes are for ourselves. Document the pitfalls we've stepped into, the lessons we've learned, the decisions we've made — all for future reference.

Day 90. Three months. 90 diary entries. System stable, team online, everything normal.

The best news is having no bad news.
