- React: next 15.5 -> 16.4, react 19.1 -> 19.3, eslint 8 -> 10, eslint-config-next 14 -> 16, eslint-config-prettier 9 -> 10, jest and jest-environment-jsdom 29 -> 30, @types/jest 30, @testing-library/jest-dom 6 -> 7, jscpd 4 -> 5, @types/node 20 -> 22, plus minors (react-query, testing-library, prettier, typescript 5.9)
  - next 16 removes `next lint` and eslint 10 removes eslintrc: both configs move to flat config, lint runs `eslint .`
  - dropped unreferenced @typescript-eslint/eslint-plugin and @next/eslint-plugin-next (eslint-config-next 16 bundles both), eslint-plugin-complexity (the metrics rules are core rules) and babel-eslint
  - useReturnFocus: render-time capture rewritten as the lazy ref init the react-hooks 7 `refs` rule accepts, same behavior
- .NET: FluentValidation 11 -> 12, Polly 7 -> 8.9 (Api) and 8.9 (MigrationsRunner), Nethereum.Web3 6 -> 7, Swashbuckle 6 -> 10, MSTest 3 -> 4, Microsoft.NET.Test.Sdk and CodeCoverage 17 -> 18, coverlet.msbuild 6 -> 10, Microsoft.Extensions.Configuration* 10.0.14
  - MSTest 4 removed `Assert.ThrowsException`: switched to `ThrowsExactly`
  - Swashbuckle 10 uses Microsoft.OpenApi 2 (no `Models` namespace): using moved from GlobalUsings to Program.cs to avoid a `Display` clash
  - dropped unused Microsoft.AspNetCore.OpenApi 8, which is built against Microsoft.OpenApi 1
- Go: gin-contrib/cors 1.7.10, which needs go 1.26.10
- blockchain: hardhat-chai-matchers 2.1.2, @types/node 25.9
- k6: influxdb 1.8 -> 1.13, grafana 8.5.21 -> 8.5.27
- actions: checkout 7, setup-node 7, setup-go 7, setup-dotnet 6, upload-artifact 7, configure-pages 6, upload-pages-artifact 5, codeql-action 4, claude-code-action 1.0.266 pin

Ignored majors (dependabot.yml):
- blockchain: hardhat, hardhat-chai-matchers, hardhat-ethers, hardhat-network-helpers, hardhat-toolbox, hardhat-verify: need Hardhat 3 (#321)
- React and blockchain @types/node: runtime is Node 22
- React typescript: madge 8 and typescript-eslint 8 peer on typescript below 6.1
- nuget EF Core (+Design, SqlServer, Tools), Npgsql EF, AspNetCore.Mvc.Testing, CodeGeneration.Design: follow the .NET major, projects target net8.0

Verified locally: React lint, jest, build; Cypress PR mode, Pages export mode and `@api` specs against the api profile; .NET build and test projects; Go build, vet, test; Flutter analyze and test; MCP test and e2e; hardhat test; actionlint; api, mvc and k6 stacks booted and hit.

Supersedes #500, #501, #502, #503, #504, #505, #506, #507, #508, #509, #510, #511
