A one-time, crash-safe import of existing Hive boxes into a drift SQLite database on the user's device: schema design, the import function, idempotency, deleting the boxes, and the two gotchas that silently corrupt data (DateTime precision and class-name collisions). Tested on Flutter 3.44.8 with hive_ce 2.22.0 and drift 2.35.2.

Upgrading a Blazor Web App whose pages live in a Razor class library or a .Client project from .NET 8 to .NET 10: what stays the same (both AdditionalAssemblies registrations), and the four things that break, from a 404 on blazor.web.js in thin hosts to NotFoundPage pages that render blank. Measured on ASP.NET Core 8.0.32 and 10.0.10.

Flutter 3.44 made Swift Package Manager the default for iOS and macOS, but an existing app keeps CocoaPods until you remove it. How to check which plugins are SwiftPM-ready, let the tool migrate the Xcode project, delete the Podfile safely, handle pods-only plugins and custom Podfile logic, and roll back if you need to.

Flutter 3.47 makes Impeller the default renderer on Windows and Linux. What actually changes underneath (it is still OpenGL ES, not Vulkan), how to A/B test against Skia on a built binary, a per-machine kill switch for release builds, and why your golden tests will not notice.

Flutter moved PageTransitionsBuilder and two built-in builders into the widgets layer and CupertinoPageTransitionsBuilder out of Material. What actually breaks (one import, with a misleading 'Not a constant expression' error), what dart fix does and gets wrong for material_ui projects, and how to rewrite custom builders and routes so they no longer depend on Material at all.

Move a repo, its Cursor cloud agents, automations, Bugbot, and CI from GitHub to Cursor Origin without a flag day: mirror first, rewire agents and CI while GitHub is still the source of truth, then cut over with Detach from GitHub or the reversible inbound_to_outbound mirror transition. Covers what breaks, the Origin CLI and API calls, a ref-parity check, and the rollback path.

Claude Code 2.1.277 reads AGENTS.md natively, so Cursor, Claude Code, and most Copilot surfaces can now share one instructions file. Here is the checklist for merging three drifted rule files into AGENTS.md, which bridge files to delete, the one Copilot file you still have to generate, and a CI check that keeps them from drifting again.

Move a local stdio MCP server to a remote Streamable HTTP server behind OAuth on MCP spec 2026-07-28 and TypeScript SDK 2.0.0. Dynamic Client Registration is now deprecated, so use Client ID Metadata Documents first and keep DCR only as a fallback. Covers the steps, a measured CIMD/DCR test matrix, and the misleading error you get when the two sides disagree.

EF Core 11 stops escaping '/', '\', '?' and '#' in generated Cosmos DB id values, so documents written by EF Core 8-10 stop resolving by key. How to find out if you are affected, when to set the EscapeIllegalCosmosIdCharacters switch, and how to rewrite the ids safely with a transactional batch.

The full path from an AGP 8 Flutter app that applies kotlin-android to AGP 9.1 with android.builtInKotlin=true on Flutter 3.47. Every step was built and measured, including the two edits that look optional and are not: kotlinOptions is a compile error under KGP 2.2+, and the KGP line in settings.gradle.kts has to stay.
