Block shape storage for a pre release Etheria, with the inner loop bound wrong

Frontier EraVerified Source

Historical Significance

Etheria was a world with a map, a terrain and rules about what could be built where, put on chain in 2015 when almost nothing on Ethereum kept state worth looking at. Its author had to solve a problem nobody had a pattern for: the map is too large to write in one transaction and useless until it is complete, so the storage contracts fill themselves in over many calls and lock once the last piece lands. Sealing a contract against its own author is a deliberate commitment, made before immutability was a slogan.

Context

Frontier era deployment by Cyrus Adkisson, the author of Etheria.

Description

Deployed ten minutes before 0x57cdd5582a02e53e833ea4592ec8296110e5f884 and identical to it except that both copy loops run their inner index to 8 rather than 3, so only the first of every three coordinates written by initOccupies and initAttachesto lands where it was meant to. The corrected redeployment followed the same afternoon.
