. Here is the required output summary:

1. Executive Summary
Sprint 1 delivered all four Core Utilities tasks on scope, on architecture, and without kernel violation. The Sprint 0 framework kernel is intact — the only permitted kernel change was the additive instanceof MiddlewareInterface check in MiddlewarePipeline::wrap() (CORE-001). All four layouts serve assets locally. Zero external JavaScript CDN dependencies remain at page render time.

One risk materialized (R-S1-02: Node.js unavailable) and was resolved without deliverable impact via the Tailwind v3 standalone CLI. The security surface is reduced: 2 external CDN script sources eliminated.

2. Technical Debt Summary
ID	Description	Severity	Sprint
TD-001	Middleware Interface Missing	—	RESOLVED (CORE-001)
TD-002	Content Security Policy Not Implemented	Medium	Sprint 3 pre-checklist
TD-003	Log File Rotation Absent	Low	Pre-launch
TD-004	TailwindCSS CDN in Production Layouts	—	RESOLVED (CORE-003/004)
TD-005	Google Fonts Loaded Externally via CSS @import	Low	Sprint 2+
TD-006	Asset Build Pipeline Not Repository-Reproducible	Low	Before Sprint 2 views
Net TD position: unchanged — 2 resolved, 2 new, 1 Medium + 3 Low remaining.

TD-006 Sprint 2 flag: Sprint 2 authentication views will introduce new Tailwind classes absent from the current purged app.css. CSS recompilation is required before Sprint 2 views render correctly.

3. DRP Recommendation
Option A — No DRP Required. Architecture remains valid. All Sprint 1 implementations are consistent with MIB v1.1, DBP v1.1, ADR v1.0, and SPRINT1_PLANNING.md. No architectural decision requires formal review.

4. Sprint Acceptance
Sprint 1 accepted with observations.

All four CORE tasks: scope-compliant, architecturally correct, fully documented
Sprint 0 kernel frozen and intact
TD-001 and TD-004 resolved
Two observations for Sprint 2 pre-planning: build pipeline reproducibility (TD-006) and CSRF route wiring (AF-002)
5. Recommended Next Step
Sprint 2 Planning — Authentication.

Before Sprint 2 implementation begins, address TD-006: commit a build configuration file (tailwind.config.js + build.ps1) so that Sprint 2 authentication view CSS compiles correctly.
