The walkthrough generator moved to async export queues to stop timing out on large composites, and the channel-aware memory budget model got a conservative overhaul after OOM incidents on multi-channel composites.
The composite pipeline gained per-tile gain normalization to eliminate exposure-level grid artifacts, quality scoring via HTTP response headers, and HDR auto-stretch for extreme dynamic range targets like the Crab Nebula. Coverage-aware filter selection in the recipe engine now handles RA wraparound correctly.
Massive infrastructure day. The composite pipeline got streaming reprojection to stop loading entire FITS files into memory, auto-stretch parameters learned to compute themselves from channel statistics, and a security audit scrubbed hardcoded paths and AWS IDs from the codebase.
Seven PRs shipped — most of them fixing things that were silently wrong. Auto-crop removes the black borders that made every composite look like a padded square. Recipes now filter out non-science observations. And the composite pipeline finally routes through the authenticated API client like everything else should have from the start.
A two-part day. Morning: visual polish, bug fixes, and infrastructure cleanup. Afternoon: the recipe engine learned to look at the sky — cross-instrument composites now only combine observations that actually overlap. Plus a 52% main bundle reduction by lazy-loading page routes.
A marathon session: 24 pull requests merged (9 features, 6 fixes, 8 docs). Major work on the composite imaging pipeline.
