. 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.

3:12 AM
Structure is clean and complete. All sections in sequence, all TD and AF entries correctly numbered.

Editorial Changes Summary
Change 1 — TD-006 Title Renamed
Before: TD-006 — Asset Build Pipeline Not Repository-Reproducible
After: TD-006 — Build Configuration Not Yet Versioned

The repository is reproducible — the committed outputs are correct. The precise concern is that the Tailwind configuration file and build script are not yet committed. The description, resolution, severity, and recommended sprint are unchanged.

Change 2 — AF-001 Reclassified as Technical Debt
Removed from §10 Architecture Findings: AF-001 — Asset Pipeline Reproducibility Gap

Added to §8 Technical Debt Register: TD-007 — Build Tooling Not Committed

The original AF-001 described a developer-experience and repository maintenance concern (binary not committed, build reproducibility for new developers). This is not an architectural issue. The architecture is correct — assets are in the right locations, served correctly. The concern is operational: a developer setting up the environment must re-download the CLI binary. Reclassified as TD-007 (Low). The original AF-002 (CSRF not yet wired) is the only genuine architectural note and becomes AF-001.

Change 3 — Lessons Confirmed Section Added (§14)
New section inserted before the Final Recommendation (which becomes §15). Records five governance confirmations: scope containment, kernel boundary respect, extension point sufficiency, documentation-first workflow, and zero DRP requirement.

Change 4 — Consistency Fixes
Item	Fix Applied
Header Sprint Status	Updated to "Accepted with Observations"
Executive Summary	Updated TD count from "Two new" to "Three new"; updated TD-006 description
CORE-003 §3.3 Future Scalability	Cross-reference updated to TD-006 and TD-007
CORE-004 §3.4 Future Scalability	Cross-reference updated to TD-006, TD-007
DRP Recommendation §11	Updated to reference three TD items; note about AF-001 reclassification added
Sprint Scorecard §12	Maintainability note updated to reference TD-006 and TD-007
Final Recommendation §15	Observation 1 references TD-006 and TD-007; Observation 2 references AF-001 (renumbered)
Out of Scope §16	Build entry updated to "Sprint 2 pre-checklist"
Footer	Finalized: 2026-07-02 and Version: 1.0 (Final) added
Section numbers	§14 Lessons Confirmed → §15 Final Recommendation → §16 Out of Scope
