- Original GURPS conversion by Enraged Eggplant, from Monsters (May 11, 2024); adapted and republished with permission.
- GCS ancestry draft: gcs/locathah.gct
- Source template total: 23 points.
- Library-rebuilt template total: 23 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 9, PR 5, CER 14, threat tier minor.
- Conversion baseline reported OR 10, PR 5, CER 15 (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.
- 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.
