Architecture implementation status

This is the authoritative status for the unreleased 0.62.0 working tree. A source module or local test alone does not make a feature production-ready.

Status meanings:

• Not Started: no usable implementation.
• Scaffolded: types, helpers, or simulations exist, but no production path.
• Integrated: a production path exists, but the release qualification gate is incomplete.
• Qualified: exact-SHA CI and packaged-artifact evidence passed. This state is recorded per R1-R10 task in the generated certification artifact's architecture_tasks field.

Source rows remain Integrated until evidence exists. The generated manifest binds this file through implementation_status_sha256, so CI fails if the matrix is incomplete or malformed.

ID	Status	Source	Tests	CI job	Last qualified SHA	Known limitations
R1 Shared-handle authority	Integrated	crates/mongreldb-core/src/handle.rs, manager.rs, database.rs	crates/mongreldb-core/tests/shared_handles.rs	workspace tests		Exact-SHA qualification remains required.
R2 Native RPC	Integrated	crates/mongreldb-protocol/proto/, src/native_transport.rs, crates/mongreldb-server/src/native.rs, admission.rs, crates/mongreldb-client/src/native.rs	crates/mongreldb-protocol/tests/native_proto.rs, native_transport.rs, crates/mongreldb-server/tests/native_rpc.rs, adapter_parity.rs, scheduler_admission_test.rs	workspace, server, and client tests		Native and HTTP SQL share hierarchical admission. Exact-SHA packaged qualification remains required.
R3 Production security	Integrated	crates/mongreldb-core/src/security_hardening.rs, crates/mongreldb-server/src/oidc.rs, native.rs, vault_kms.rs	security module tests, crates/mongreldb-core/tests/kms_encryption.rs, and crates/mongreldb-server/tests/native_rpc.rs	workspace and server tests		Exact-SHA qualification remains required.
R4 MySQL migration and wire	Integrated	crates/mongreldb-migrate-mysql, crates/mongreldb-mysql-wire	real MySQL container and external mysql_async client tests	CI / MySQL wire compatibility, Qualification nightly / Real MySQL migration		Exact-SHA qualification remains required.
R5 Generated embedding writes	Integrated	crates/mongreldb-core/src/embedding.rs, schema.rs, database.rs, columnar.rs; MongrelDB-Kit Rust/TypeScript/Python GeneratedColumnSpec schema	crates/mongreldb-core/tests/generated_embeddings.rs; MongrelDB-Kit schema and provider tests	workspace tests		Synchronous AbortWrite is the explicit policy; exact-SHA qualification remains required.
R6 Provider hardening	Integrated	crates/mongreldb-core/src/embedding.rs, crates/mongreldb-server/src/remote_embedding.rs	embedding unit/integration and remote configuration tests	workspace and server tests		Exact-SHA qualification remains required.
R7 Production certification	Integrated	crates/mongreldb-core/src/certification.rs, fuzz/, scripts/generate-certification-manifest.py, scripts/qualify-packaged-artifacts.sh	release workspace tests, five fuzz targets, kill-at-hook durable crash matrix, packaged server/C ABI conformance	Qualification nightly / Full tests, Qualification nightly / Extended parser fuzz, Clean release qualification		Local release tests passed in the dirty working tree. No manifest exists until the clean exact-SHA CI job passes.
R8 Documentation truth	Integrated	this file, public architecture docs	certification manifest validation	Clean release qualification		Exact-SHA qualification remains required.
R9 Public operational contract	Integrated	public API, operations docs, and this matrix	subsystem and adapter tests	Clean release qualification		Exact-SHA qualification remains required.
R10 Exact-SHA evidence	Integrated	scripts/generate-certification-manifest.py	clean artifact conformance	Clean release qualification		Qualification for pre-0.62.0 SHA b6fc52b remains in progress; no successful fresh-checkout 0.62.0 artifact exists.

Public documentation may describe Integrated behavior precisely, but must not call it Qualified or production-certified. Updating a row to Qualified requires all referenced tests, the relevant packaged clients, and the release artifact checks to pass for the same commit SHA.
