Phase 1 — close SF-side polish gaps:
- codebase-generator: distinguish uv/poetry/pdm in Python stack-signals;
surface configured tooling (ruff/mypy/pyright) when config files exist
- doctor-environment: new checkPythonEnvironment — detects uv/poetry/pdm
via lockfile, verifies binary on PATH, warns with install hint when missing
- doctor-environment: new checkSiftAvailable — recommends sift install for
repos > 5000 source files when not on PATH
- tech-debt-tracker: documented future memory-as-sub-extension extraction
(defer until real backend-swap requirement)
Phase 2 — internal wire architecture:
- ADR-020: singularity-grpc as shared schema repo; gRPC + typed clients
for first-party services; MCP façade only at external-tool boundary
- ADR-019: trimmed MCP scope section to a 3-line summary linking to ADR-020
to avoid the wire-format table living in two places
- design-docs/index.md: ADR-020 added to ADR table
These changes make SF stronger for autonomous work on Python repos
(particularly ace-coder) and capture the internal wire architecture
decision as a durable ADR before any singularity-grpc code lands.
