# MCR Development Progress

Reverse-chronological log of development work. Most recent entries first.
See `PROJECT_PLAN.md` for the implementation roadmap and
`ARCHITECTURE.md` for the full design specification.

## Current State

**Phase:** Pre-implementation
**Last updated:** 2026-03-19

### Completed

- `ARCHITECTURE.md` — Full design specification (18 sections)
- `CLAUDE.md` — AI development guidance
- `PROJECT_PLAN.md` — Implementation plan (14 phases, 40+ steps)
- `PROGRESS.md` — This file

### Next Steps

1. Begin Phase 0: Project scaffolding (Step 0.1: Go module and directory
   structure)
2. After Phase 0 passes `make all`, proceed to Phase 1

## Log

### 2026-03-19 — Project planning

**Task:** Create design documents and implementation plan.

**Changes:**
- `README.md`: Existing one-line description
- `ARCHITECTURE.md`: Full design specification covering OCI Distribution
  Spec compliance, MCIAS authentication, policy engine, storage design,
  API surface (OCI + admin REST + gRPC), database schema, garbage collection,
  configuration, web UI, CLI tools, deployment, security model
- `CLAUDE.md`: Development guidance for AI-assisted implementation
- `PROJECT_PLAN.md`: 14-phase implementation plan with discrete steps,
  acceptance criteria, dependency graph, and batchable work identification
- `PROGRESS.md`: This progress tracker

**Notes:**
- No code written yet. All files are documentation/planning.
- ARCHITECTURE.md reviewed and corrected for: GC algorithm crash safety,
  policy glob semantics, tag FK cascade, OCI error format, API sync
  violations, timeout configuration, backup considerations, and other
  consistency issues.
