Entry

Entry is a single signed guestbook line.

Sign

Sign appends a new entry to the guestbook attributed to the immediate caller. It is a crossing function (gno 0.9 interrealm convention): callers invoke it as Sign(cross(cur), "hello"). The cur.IsCurrent() guard is the authentication primitive — without it a stale/forged realm value could spoof the author.

addEntry

addEntry validates the message and appends an entry. Non-crossing internal helper so the append/validation logic is unit-testable without a realm frame. Panics (aborting the tx, reverting state) on an invalid message.

Count

Count returns the total number of signatures. Read-only, non-crossing.

Render

Render lists every entry newest-first as a Markdown table plus a total count.

seqKey

seqKey renders a sequence number as a fixed-width, zero-padded string so avl's lexicographic key order matches numeric order.

shortAddr

shortAddr abbreviates a bech32 address for compact display.

escapeCell

escapeCell neutralizes characters that would break a Markdown table cell.
