The stage drew a dot per note and left the reader to guess. A dot travelling
inward could be anybody paying anybody, and without text beside it the
animation is an ornament rather than a reading of the chain.
Each pulse now carries a sample of the individual notes — kind, recipient,
amount — and a console below the stage lists them newest-first, the way the
block ticker reads, which also means no auto-scroll to fight with and the line
a reader is looking for never moves.
`kind` is the third split this codebase makes on the producing extrinsic and
the first that separates all three cases: a reward has no extrinsic at all
because it is paid in block initialisation, a transfer has an ordinary one, and
an exit has a `verify_*_batch`. The recorded sender distinguishes none of them.
Two caps, and they turned out to interact. `MAX_PULSE_NOTES` bounds the wire —
a block has carried hundreds of notes and sending every one for a handful of
lines is kilobytes a block of text nobody reads. `CONSOLE_LINES_PER_BLOCK`
bounds one block's share of the console, because without it a single busy block
fills every line and twelve lines from one block look exactly like twelve
blocks of one, which loses the reader all sense of rate.
The count of what is not shown hangs on the block's first line rather than its
last: the list is newest-first, so a count on the last line is the first thing
trimmed, and a block of 260 showed four notes while saying nothing about it.
That one reached a screenshot before it was caught.
The console fills before the reduced-motion guard, so a viewer who asked for
less motion still gets the whole reading — twelve lines, no moving marks,
population still drawn, caption still live.
