# Phase Completion Reports

Engineering completion reports for the L1 Developer Infrastructure work plan. Each report covers a single phase: what was in scope, what shipped, how to use it, and what was explicitly deferred (with rationale).

Reports here describe **delivered** work — they are not roadmap documents. For in-flight status across all phases see the project memory tracker.

| Phase | Title                                                                        | Status                                                                                                                                                |

## Format

Each report follows the same structure:

1. **What this phase covers** — scope and starting state.
2. **What we built** — concrete deliverables, with tables for at-a-glance browsing.
3. **How to use what was built** — runnable commands a reader can copy.
4. **Why it matters** — the operational or developer value, not just the change list.
5. **Files & commits** — exact paths and commit SHAs for traceability.
6. **Deferred work** — what was *not* done, with a brief justification.
