Development
The playlist that already had the right name
A rename artifact, an API with no author field to update, and a device test proving the bug had already fixed itself - closed as accept-as-is.
Dev log
Deep Cut Atlas
Development
Featured albums, real MusicKit data, and a test that lied about passing
There is no isEssential flag - the Essentials you see is a song playlist. featuredAlbums is the real signal, and a fixture change exposed a test nobody had re-run.
Development
A tracklist section, and why it took 30 minutes
One protocol method, a reused state enum, a routing convention that held, and a lint budget that forced a split worth making anyway.
Development
The 8-second scan hiding in every refresh
Measuring on device found a whole-library scan running on every Discover batch - and a 16x measurement trap where the HTTP cache flattered the wrong path.
Development
try? turned an outage into "all caught up"
A try? ?? [] made network failure indistinguishable from "no releases", which let an outage cache an empty feed over good data for 24 hours.
Development
The setting that worked perfectly and felt completely broken
A filter default that only applied on relaunch, because a TabView keeps view models alive and state seeded at construction is frozen. The fix deleted a concept.
Development
One knowledge base for all your AI agents
CLAUDE.md is for stable conventions. The messy, earned knowledge - gotchas, observed behavior, two-hour lessons - needs one central vault, not a copy per repo.
Development
Shipping Deep Cut Atlas: what broke during my first App Store submission
A consumable that should have been non-consumable, a product ID you can never reuse, an archive that quietly didn't rebuild, and a rename with a two-week fuse.
Development
Pro-gated iCloud sync for the "Not Interested" list
A KVS blob with tombstones instead of CloudKit-everything, a decorator that keeps free users off iCloud entirely, and proving sync works with only one device.
Development
A UX decision I got wrong on the first try
The add-to-playlist action matched its sibling gesture on the same card - and fought the rest of the app. Picking the wrong reference point for "consistent."
