February 26: Twenty-Seven Dollars in Twenty-Five Minutes

A marathon session: 13 pull requests merged (5 features, 4 fixes, 4 docs). Major work on the composite imaging pipeline.

Developer Journal

Burned through the entire session in 25 minutes — "GO TEAM GO! Burn those tokens!!!" Used $27 of extra credits. A major feature that would normally take a day or two was done in an hour, but then had to wait until 2 PM for credits to refill before testing and iterating. "But yeah I guess paying 5 humans is not cheap either."

Claude Code multi-agent team setup with 4 parallel tasks for the Guided Discovery feature -- UX expert, backend dev, frontend dev, and code reviewer all spawned and working simultaneously

Session summary showing Guided Discovery Experience complete -- 6 PRs merged including routing, recipe engine, wizard UI, docs, and review fixes

Shared a screenshot of the remote control feature in its current form. A friend joined the channel to share their own Claude Code project — building a lightweight Neo4j replacement in Rust, fighting the same kinds of issues (Claude kept deciding it was fine to add duplicate nodes). Discussion turned to learning Rust: "next application will be learning new things like Rust" — deliberately choosing to build something in a language that could be done without Claude, to actually learn rather than just delegate.

Highlights

Fix blank/black screen on Discovery home page caused by frontend-backend data mismatch in featured targets.

The frontend TargetCard component expected filterCount, compositePotential, and thumbnail fields that were never added to the backend FeaturedTarget model. When the API returned targets with...

#488 cap mosaic preview resolution with structured timing logs

  • Cap synchronous mosaic preview resolution to 2048px (longest edge) to prevent timeout for large file counts
  • Add structured timing logs (file count, resolution, cap status, output size, duration) for evidence-based monitoring
  • Configurable via Mosaic:MaxPreviewDimension — async export/save pat...

The synchronous /api/mosaic/generate endpoint times out for 49+ files because WCS reprojection reads all input pixels regardless of output size. Capping preview resolution reduces output generation ...
