Release 3.0.0-rc.1 readiness

[rodri-oliveira-dev]

Summary

This PR prepares the forked 3.0.0-rc.1 line against master, collecting the changes accumulated since the last published upstream version/tag (v2.0.0). It is intentionally opened as a draft so the release evidence and remaining publication decision can be reviewed before merge.

What changed since the last version

• Added generated materialization contracts, source generator registration, generated flat/complex materializers, runtime fallback integration, and benchmark coverage.
• Added persistence metadata for FluentMap properties, including read-only, computed, database default, key/identity/generated semantics, and Dommel integration for write operations.
• Added advanced mapped query APIs, including mapped multiple-result reads, MappedGridReader, unbuffered reads, and async streaming.
• Added property converter metadata and runtime/generated read conversion support, with analyzer/runtime validation for invalid or duplicate converter configuration.
• Added isolated configuration support through immutable configuration snapshots, FluentMapRuntime, compatibility bridge behavior for the static API, and a new Dapper.FluentMap.DependencyInjection package.
• Added analyzer/generator diagnostics and release tracking manifests for the new DFM001-DFM015 diagnostic surface.
• Added provider compatibility tests, consumer smoke apps, package artifact validation, vulnerability audit, SourceLink/provenance validation evidence, and release workflow hardening.
• Added public release documentation: CHANGELOG.md, COMPATIBILITY.md, MIGRATION.md, SUPPORT.md, and SDD evidence for Etapas 7-12 and the RC cycle.

Release and packaging notes

• The intended package version is 3.0.0-rc.1; default local package output is guarded as development prerelease output rather than accidentally producing 2.0.0 or stable 3.0.0.
• Package validation is enabled for runtime packages with lib/: Dapper.FluentMap, Dapper.FluentMap.Dommel, and Dapper.FluentMap.DependencyInjection.
• Release artifact validation covers expected package IDs, versions, nuspec metadata, dependency ranges, package layout, repository metadata, README/license presence, and SHA-256 manifests.
• Consumer smoke validates package consumption without ProjectReference for core, Dommel, Dependency Injection, analyzer, generator, and trimmed publish scenarios.

Known limitations / release status

• 3.0.0-rc.1 publication was blocked because .sdd/release-3.0.0-rc.1/PUBLISH-AUTHORIZATION.md was absent.
• No NuGet packages were published, no v3.0.0-rc.1 tag was created, and no GitHub Release was created as part of the recorded RC.6 outcome.
• SQL Server and PostgreSQL provider certification remain conditional on real connection strings/services; SQLite is the automated provider-certified lane.
• Native AOT is not claimed as fully supported; trimming smoke exists for explicit/generated registration paths.
• Package signing, formal SBOM, and fork-owned API/binary baseline remain stable-release decisions/blockers.

Validation recorded in the branch

• dotnet restore ./Dapper.FluentMap.sln
• dotnet build ./Dapper.FluentMap.sln --configuration Release --no-restore
• dotnet test ./Dapper.FluentMap.sln --configuration Release --no-build
• provider compatibility tests with SQLite, with SQL Server/PostgreSQL skipped when connection strings are absent
• dotnet pack ./Dapper.FluentMap.sln --configuration Release --no-build -p:Version=3.0.0-rc.1
• eng/validate-release-artifacts.ps1
• eng/consumer-smoke/run-consumer-smoke.ps1
• SourceLink validation for package PDBs from remote artifacts
• GitHub artifact attestation/provenance validation for remote artifacts
• dotnet list ./Dapper.FluentMap.sln package --vulnerable --include-transitive

Review focus

• Public API and binary compatibility policy for the fork-owned 3.0.0 line.
• Whether the release workflow and publication authorization model are acceptable before retrying RC publication.
• Whether remaining stable blockers should stay out of RC.1 or require an RC.2 before stable.

Reutilize a instância configurada do conversor gerado

Quando ConvertFromDatabaseUsing<TConverter, TDatabase>() usa um conversor com estado por instância ou inicialização dependente do ambiente, este campo cria uma segunda instância global, diferente daquela criada e armazenada no PropertyMap. Como o materializador é selecionado comparando apenas os tipos do conversor, consultas geradas passam a produzir resultados diferentes do fallback e runtimes isolados compartilham indevidamente o mesmo conversor estático; registre o materializador com a instância capturada pela configuração ou não gere esse caminho sem poder preservá-la.
