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.

ADR-019 framing corrections:
- SF is single-machine, single-user, single-repo by design — character, not
limitation. Stays a standalone app permanently; does not get absorbed into ACE.
- Phase 6 reframed: "pattern transfer" not "orchestration convergence." ACE
ports patterns from SF, both apps remain independent.
- Phase 2 reframed: SF stays local. Federation is an ACE concern; SF doesn't
wire memory-store remote-mode against singularity-memory.
Detection strengthened for Python (priority for ace-coder work):
- Detect uv / poetry / pdm and prefix verification commands accordingly
- Emit ruff check when configured (file or [tool.ruff] in pyproject.toml)
- Emit mypy / pyright when configured — skip when no config to avoid false fails
- pyprojectHasTool helper for [tool.<name>] section detection
Detection strengthened for Rust:
- cargo fmt --check (fastest, catches style first)
- cargo check (type-only, faster than test)
- cargo clippy -- -D warnings (warnings as errors)

Internal services (SF↔memory, ACE↔memory, SF↔ACE) talk via typed direct
clients generated from the Go/TS APIs — HTTP/gRPC for memory, existing
JSON-RPC stdio for SF↔ACE. MCP is reserved for external LLM-driven coding
tools (Claude Code, Cursor) that don't share our build system; it is a
scaffold for the period when external coders help build the platform and
shrinks as the system becomes self-hosting.
Adds an explicit "MCP scope" table so the rule is stated once. Updates the
three-layer architecture diagram, Phase 2, and Phase 6 to remove the
inaccurate "all consumers over MCP" framing.

Captures the SF↔ACE incremental convergence strategy: workspace VMs
(Firecracker) as the unified execution isolation primitive, the three-layer
architecture (orchestration/knowledge/execution), the 6-phase convergence
path, and ADR-014 Phase 4 cancellation (persistent-agent runtime reassigned
to ACE). Cross-references the matching ACE document at
docs/architecture/sf-ace-convergence.md.
