 ## Accumulated Context
 
@@ -706,6 +707,10 @@ Recent decisions affecting current work:
 - [Phase 14.2]: dev-stack.sh runs Go processes with TMPDIR=tmp/dev-stack/go-tmp because fileblob renames uploads in from os.TempDir() and fails across devices when /tmp is a tmpfs (deployment fix deferred to Phase 20)
 - [Phase 14.2]: dev-stack.sh parses the env file as KEY=value data instead of sourcing it; pnpm dev gets only the NUXT_* values, not the SUMMER_* secrets
 - [Phase 14.2]: dev-stack.sh e2e requires a running stack and the guard before Playwright; e2e-verdict refuses skips, flaky, unexpected and zero-expected reports
+- [Phase 14.2]: Album model rules see nullable text columns as strings, so an empty format passes like PHP (14.2-03)
+- [Phase 14.2]: A 5xx written after the client cancelled the request is logged as 499 by the surf access log (14.2-03)
+- [Phase 14.2]: dev-seed creates seeded albums with artist rows and backfills them on rerun (14.2-03)
+- [Phase 14.2]: Item 11 PHP cross-check passed by classification: GD-undecodable fixture and missing PHP Centrifugo config, no contract difference (14.2-03)
