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

9	Observability & Correlation	100% Dev-Infra ceiling — build-info + structured logs + OTel SDK + SLO/cost dashboards; collector deploy external
10	Security, Compliance & Supply Chain	100% Dev-Infra ceiling — Cosign + SLSA L2 + CodeQL (23→0) + license policy + audit-trail emission; SIEM out-of-scope

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.
