Conversation
Captures the architectural decision to refactor the CLI from a fat client (embeds engine, validators, formatter, remediation) back to a thin gRPC presentation layer per the original ADR-001/ADR-004 design. Introduces a local daemon mode that runs Primary + validators as localhost gRPC servers, giving standalone users the same architecture as the Podman pod without requiring containers. Includes phased rollout plan and new FixStream/FormatStream RPC definitions. Made-with: Cursor

Pull request overview
Adds a new architecture decision record (ADR-024) proposing a shift back to a thin gRPC CLI by introducing a local “daemon mode” that runs Primary + validators locally, aligning standalone development with the pod architecture.
Changes:
- Add ADR-024 documenting the thin-CLI + local daemon approach and phased rollout plan.
- Update the ADR index/metadata in
.sdlc/adrs/README.mdto include ADR-024.

- Align daemon state file path with existing ~/.apme-data/ convention (ADR-022) instead of introducing ~/.apme/ - Clarify session subcommand becomes gRPC pass-through rather than removed; add ADR-022 to Related Decisions - Replace .cursor/plans/ references (gitignored) with PR links - Add missing ADR-022 to index table, changelog, and categories Made-with: Cursor

This ADR was developed through an architecture review of the engine and CLI scope analysis. The fat CLI problem was identified during PR #34 review, where
collection_specshandling diverged between local and gRPC scan paths — a direct symptom of dual code paths. The daemon approach aligns local development with the pod architecture and enables a web UI as a second gRPC client without reimplementing orchestration logic.Made with Cursor
