[Content] Publish complete DP-700 objective-aligned study chapters

[troyscott]

Outcome

Publish a comprehensive, original DP-700 study book aligned to all 54 objectives in the current official Microsoft Study Guide. Microsoft Learn remains authoritative; chapters explain, compare, demonstrate, and test the material rather than reproducing Learn pages.

Definition of complete

An objective is complete only when all applicable elements are present:

• Conceptual model and precise terminology
• Responsibilities, prerequisites, and security boundaries
• Configuration or implementation procedure
• Decision criteria and trade-offs
• Worked SQL, PySpark, KQL, Power Query, or configuration example
• Product limitations and common failure modes
• Troubleshooting and monitoring evidence
• Exam distinctions and likely traps
• At least two objective-specific active-recall questions
• A scenario or mini-lab for each major topic
• Exact current Microsoft Learn sources with retrieval date and content hash

Word count is a warning signal, not proof of completeness.

Implementation phases

Phase 1 — Comprehensive coverage contract

• Build a 54-row objective and subtopic audit
• Map each subtopic to current official Microsoft Learn documentation
• Add machine-readable coverage fields for concepts, procedures, examples, failures, questions, and sources
• Replace chapter-level minimum-word validation with objective-level completeness validation

Phase 2 — Implement and manage an analytics solution

• Complete workspace settings coverage
• Expand Git integration, database projects, and deployment pipelines
• Expand the Fabric and OneLake security model
• Add complete Dataflow, notebook, and pipeline orchestration patterns

Phase 3 — Ingest and transform data

• Add full and incremental loading implementations
• Add dimensional loading and slowly changing dimension examples
• Add detailed Dataflow Gen2 transformation walkthroughs
• Cover query folding, schema behavior, and destination behavior
• Compare shortcuts, mirroring, copy jobs, and pipeline copies
• Add PySpark, SQL, and KQL implementations
• Expand Eventstreams, Structured Streaming, KQL, windows, watermarks, and late-data handling

Phase 4 — Monitor, troubleshoot, and optimize

• Add Monitoring hub and item-specific operational workflows
• Expand semantic model refresh and Activator alerts
• Add evidence-led diagnostics for all seven error objectives
• Add Delta, Warehouse, Spark, pipeline, Eventhouse, Eventstream, and query optimization
• Include before-and-after measurements and scenario questions

Phase 5 — Final evaluation

• Validate all 54 objective coverage records
• Check links, retrieval dates, content hashes, and source mappings
• Verify technical examples and rendered code
• Test iPhone-sized and desktop layouts
• Complete a chapter-by-chapter editorial audit
• Publish a final completeness report before requesting human PR review

Final acceptance criteria

• All 54 measured objectives pass the comprehensive rubric
• All 10 chapters are complete and mobile-readable
• No placeholder, outline-only, or title-only coverage remains
• Dataflow Gen2 includes worked transformations, folding, schema, destination, and tool-selection guidance
• Source registry and coverage records are current and bidirectional
• Content, rendering, quality, browser-state, and responsive-layout checks pass
• PR remains draft until the final completeness report is posted

[troyscott]

Comprehensive implementation is complete in #37 and the PR is now ready for human review.

Final evidence:

• 54/54 objectives pass the ten-category coverage contract
• 35,081 words across 10 published chapters
• 41 registered Microsoft Learn sources with retrieval timestamps and SHA-256 hashes
• every chapter Learn link is registered for provenance
• 29 Python/content tests and 5 browser-state tests pass
• 92.68% statement coverage
• all 10 chapters passed the 390 × 844 responsive sweep; representative desktop rendering passed
• both GitHub Actions quality checks passed
