Summary

The 0.1.2 placeholder-heights finding: the three block ways the report flagged as guessed-height buildings are not buildings.

  • 1360755125, 1360755126 → building=roof, layer=1 (elevated canopies)
  • 1417995292 → amenity=shelter, shelter_type=public_transport (transit shelter)

The report defaulted them to "2 levels × 3.2 m", inventing the 6.4 m figure. Geo/tools/block_height_report.py now classifies roof/shelter explicitly → 0 guessed heights in the block (all 15 volumes have a real height tag, a levels derivation, or a non-building classification). No frontage building was affected and no photograph measurement was needed.

Also records the measured hero proportions for the open proportion task: envelope 0–14.50 m, colonnade (columns+capitals) 2.00–8.90 m = 47.6 %, with the part-by-part z table. Bringing it to ~55 % means taking ~1 m from the attic/parapet zone that carries the motto band and medallions — a design decision left open for owner photo review.

TODO.md updated: placeholder-heights item closed, proportion item annotated with the measurements.

## Summary The `0.1.2` placeholder-heights finding: the three block ways the report flagged as guessed-height buildings are **not buildings**. - `1360755125`, `1360755126` → `building=roof`, `layer=1` (elevated canopies) - `1417995292` → `amenity=shelter`, `shelter_type=public_transport` (transit shelter) The report defaulted them to "2 levels × 3.2 m", inventing the 6.4 m figure. `Geo/tools/block_height_report.py` now classifies roof/shelter explicitly → **0 guessed heights** in the block (all 15 volumes have a real height tag, a levels derivation, or a non-building classification).

The three ways the height report flagged as guessed-height buildings are not
buildings: two are building=roof at layer=1 (elevated canopies) and one is an
amenity=shelter (public_transport). The report's '2 levels x 3.2 m' default
invented the 6.4 m figure. block_height_report.py now classifies them explicitly;
the block now reports 0 guessed heights, all 15 volumes having a real height tag,
a levels derivation, or a non-building classification.

Also records the measured hero proportions (colonnade 6.90 m = 47.6% of the
14.50 m envelope) for the open proportion task, which needs photo review.
