5.8.8

• dw-pim-completeness: per-language completeness works with the "Completeness feature" flag on.
  The "no per-language dimension" claim is scoped to the flag-off path. Measured on DW 10.29.6, the flag-on
  index builder writes CompletionRule|<id> per index document, scored in that document's language, and a
  LanguageID + empty VariantID + CompletionRule|<id> < 100 query lists one language's gaps. Recipe,
  copy-fields-only rule, and the admin per-language badge are in rules-and-dashboards.md; the "buggy beta"
  warning is narrowed to DW 10.28. dw-pim-localization and dw-users-permissions follow.
• dw-pim-completeness: what calculate_product_completeness_for_products returns. A family-aggregate
  value per master, fieldStatuses for the master row only, and languageIds ignored. The default-image
  index fields are empty on every document; only ImageSmall drives a missing-image query.
• Masters with variants and ProductNumber. Combine stores the master number as an empty string and the
  master edit screen has no Number field, so keep ProductNumber out of completion rules (DW 10.29.7,
  dynamicweb/DynamicWeb#735). "Exclude variants" still counts the variants' Number; variant-editable category
  fields are checked per variant. dw-pim-modelling structural-model.md adds the combine side effects and
  two variant-field traps; dw-pim-workflow notes excludeVariants.
• assign_completion_rules_to_shops persists only the last request of a batch (MCP 0.6.0-BETA). Call it
  once per shop and read the assignment back; row added to dw-extend-mcp-tools tool-surface-gaps.md.
