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
6	Test Strategy & Ephemeral Environments	~70% — unit/integration/E2E live, PR preview envs deferred
7	Contract Tooling & Safety Rails	~55% — full CI matrix (compile/test/lint/slither/gas/abi/coverage)
8	SDKs & Developer Experience Portal	~65% — layered SDK shipped, tag-gated npm publish wired
9	Observability & Correlation	~90% — build-info + structured logs + OTel SDK; collector deferred

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.
