Verdict: Minor Deviation Trigger: Session end

Aligned:

• T-001 and T-002 delivered the dbt scaffold and source declarations per plan goals.
• T-003 through T-007 implemented all staging models and staging schema tests, satisfying the boundary rule to not skip staging tests.
• T-008 through T-014 implemented intermediate/mart models and mart tests without changing planned materializations.
• T-015 completed end-to-end verification with successful dbt run and dbt test.
• Progress logging was maintained per-task through T-001 to T-016.

Deviations:

• T-003 introduced deterministic fallback receipt keys for rows without NO. KWITANSI instead of leaving prior-year values null → accepted
• T-006 implemented resilient monthly/channel mapping with tenant fallback due raw REKAP header inconsistencies, instead of strict weekly decomposition → accepted
• T-016 included AGENTS command documentation updates beyond core transform SQL scope → accepted

Patterns:

• Defensive normalization/fallback patterns were consistently used for inconsistent raw headers.
• Validation-first execution pattern was maintained (tests and full runs before closure).

Recommendations:

• Keep task acceptance criteria synchronized with implementation details whenever resilient fallbacks are introduced.
• Revisit sync header normalization for raw_targets and raw_marketing_activity to reduce transform-layer complexity.
