• Completely rebuilt the new v0.7 room additions to match the detailed modular construction quality established by Hollow Spiral v0.6.0.
• Added 30 authored room variants across the eight new room families.
• Added 30 reusable architectural structure modules used to construct believable rooms instead of simple room-sized block shells.
• New rooms now feature actual corridors, walls, arches, platforms, towers, bridges, cells, shrines, pools, supports, balconies, stairs, interior spaces, broken sections, environmental detail and vertical variation.
• Preserved Hollow Spiral's four horizontal exit lanes and central UP/DOWN navigation-control area when constructing the new structures.

Abandoned Mineshafts

• Kept the Mineshaft family mechanically and visually distinct from the geology-focused Depth Mine family.

Temples

• Added Desert and Jungle temple variants.

End Cities

• Added multi-level Purpur architecture.
• Added towers, bridges, balconies and vertical traversal spaces.

• Kept End City separate from the rarer End Relic room identity.

Room Pool Cleanup

• Completely removed the obsolete standalone room implementations:

  • Coal Mine
  • Iron Mine
  • Oak Grove
  • Ruined Chamber
  • Village Workshop

• Their concepts remain represented by their more advanced replacements:

  • Coal/Iron Mine → Depth Mine
  • Oak Grove → Tree Grove
  • Ruined Chamber → Ruins
  • Village Workshop → Smithery

• Removed dead references to the old room functions.

Generation & Balance

• Rebalanced the room-generation table around all 27 active room families.
• Room generation still uses a single persistent 1–100 roll.
• Every roll value from 1 through 100 is assigned exactly once.
• Total room weighting remains exactly 100%.
• Existing room markers continue preventing previously generated coordinates from rerolling.
• Existing worlds retain generated rooms and progression rather than rebuilding the dungeon.

Stability & Validation

• Preserved the existing six-direction persistent room-grid system.
• Preserved Hollow Spiral's vanilla-mob gameplay mode.
• Preserved existing-world migration and room-maintenance behavior.
• Validated all internal Hollow Spiral function references.
• Validated all active room-family dispatch paths.
• Validated that obsolete room implementations are no longer referenced.
• Added structural validation preventing the new authored variants from reverting to oversized placeholder cuboids.

Hollow Spiral v0.7.1 is the largest room-variety expansion yet, while preserving the detailed modular room design and persistent survival structure established in v0.6.0.
