What changes here is not what a transaction may say but what a block may omit. From this height, under BIP8's mandatory-signaling period, a block that does not set bit 4 of its version is rejected — so every chapter written after it carries the signal in its frontispiece whether its miner meant it or not. The passages themselves read exactly as they did the chapter before: the same scripts, the same amounts, the same grammar. A reader would notice only in the version word at the head of each chapter.

That is the pattern of every signaled fork in this book. The rules that bind transactions arrive later, at activation; what a signaling height binds is the miners, and the record of it is a row of bits above the prose rather than a change to the prose.

Whether these three chapters ever carry these names is a question about the next few thousand blocks, not about arithmetic: the heights are fixed and the fork is not.

*Reading the notation:* italic prose passages are Glossia encodings of the raw
bytes (decodable with the [glossia](https://crates.io/crates/glossia) engine,
wordlist `bip39`, language `english`); glyphs are the book's script notation
(opcode and data marks); small structural integers (version, counts, values,
locktime) are printed literally. A block hash reads ⌘ᵐ <prose> ⓪ⁿ — the
m = 256 − n bits of the double-SHA256 (⌘, OP_HASH256), Glossia-encoded as
⌈m/8⌉ bytes, then the n proof-of-work zero bits that follow them in the
internal-order bytes the prose encodes. See
[/llms.txt](https://bookofbitcoin.io/llms.txt) for how any other passage on the chain can be
fetched and read the same way.
