Description

Written by Dungeons on Automatic, released under cc_by_4_0

• GCS ancestry draft: gcs/giant-rat.gct
• Source template total: -9 points.
• Library-rebuilt template total: -9 points.
• CER was computed from parsed Typical Stats using the Dungeons On Automatic baseline CER path.
• CER recomputed from the reviewed Typical Stats through the canonical Dungeons on Automatic CER path: OR 10, PR 9, CER 19, threat tier minor.
• Conversion baseline reported OR 11, PR 9, CER 20 (tier minor). The reviewed values come from the consumer CER implementation, which rounds damage once after the damage-type multiplier and credits ranged accuracy; the conversion baseline ceilinged the damage base first and ignored range.
• Encounter metadata derived (gregarious): average number appearing 6, wandering weight 4. Encounter metadata derived for 0.2.0 from the reviewed threat tier and creature class (appearing: minor 4 / standard 2 / major 1 / severe 1, forced to 1 for solitary classes — including swarms, which are a single multi-body creature — and raised to 6 for gregarious minor creatures; wandering weight: minor 4 / standard 3 / major 2 / severe 1). The fan-conversion source states no appearing-in-numbers or wandering values, so these are derived, not source mechanics.
• Lair, treasure, and grappling remain unpopulated in 0.2.0 by package policy: the authorized fan-conversion source states no lair, treasure, or grappling values, and review declines to invent them. See review/policy/0.2.0-empty-field-policy.md.
• Description text is original Dungeons on Automatic prose written from this record's own converted statistics and from the project's art direction for the creature. It is not derived from the authorized fan-conversion source, which states no creature descriptions, and not from any SRD. It carries its own authorship and CC BY 4.0 terms in the description field. See review/policy/description-policy.md.
• Review approved by automated-mechanical-review on 2026-07-26 (batch ee-2026-07-26-b5-cer-drift); GCS fidelity check passed, DOA playability check passed.
• The conversion baseline's published ratings disagreed with the consumer CER path; the reviewed ratings come from the consumer implementation and the difference is recorded in conversionNotes.
