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.

describeEnum has been deprecated since Flutter 3.16 and its removal PR is approved. How to replace every call with Enum.name (Flutter 3.47.4, Dart 3.13), handle enum-like classes and diagnostics, find the calls hiding in dependencies like flutter_svg 1.x, and what the build error looks like once it is gone.

Xcode 27 refuses to build anything below macOS 12, and Flutter 3.47 moved its own floor from 10.15 to 12.0. What the automatic migration rewrites, the three places it silently skips (custom values, Podfile post_install overrides, plugin podspecs), and a Podfile fix for teams still on Flutter 3.44.

Use Microsoft.Data.SqlClient. System.Data.SqlClient is deprecated, already emits CS0618 on every type you touch, and loses its .NET assets when .NET 8 goes end of support on November 10, 2026, the same day .NET 11 ships. The measured feature gap, the Encrypt default that breaks the migration, and the 7.0 package split.

dart fix takes one target directory and it can be the repo root: the analyzer opens a context per nested pubspec.yaml and migrates every package in one pass. Here is the full flag surface, the four things that silently suppress fixes and make a dirty repo report Nothing to fix, why the exit code is useless in CI, and a case where a Flutter transform emits code that does not compile.

Google Play required target API 36 from 2026-08-31, with extensions running to 2026-11-01. Here is the full .NET MAUI path from net9.0-android to API 36: the target framework bump, the hardcoded uses-sdk that silently pins you to the old level, edge-to-edge with no opt-out, predictive back, and the large-screen orientation rules.
