Frame type tags. Stable on the wire; append new variants, never renumber.

Variants

Ack = 1

Cumulative ack frontier (receiver -> sender).

Nak = 2

Selective negative ack: a block and its missing-shard bitmap.

Loss = 3

Fused loss / burstiness / delay-trend readings (receiver -> sender).

Timing = 4

Sender clock beat plus the peer beat being echoed, for RTT and OWD.

Ring = 5

Source-ring shape telemetry (the legacy heartbeat payload).

Path = 6

The peer’s observed TTL / ECN / hop-count of THIS endpoint’s packets.

Link = 7

The peer’s link class and normalized quality.

LossAcct = 8

Highest peer sequence the sender of this frame has seen, for bidirectional (forward vs reverse) loss accounting.

Pmtu = 9

The peer’s observed path MTU.

BwProbe = 10

One member of an active bandwidth probe train (packet-pair / chirp).

Trace = 11

A mini-traceroute marker riding the control stream at a chosen TTL.

AvailBw = 12

The receiver’s WBest available-bandwidth estimate (reverse-reported so the sender can cross-check its passive BtlBw).

Forecast = 13

The receiver’s Sprout-style forecast of the next-tick deliverable rate (5th-percentile lower bound), so the sender pre-sizes ahead of a dip.

Periodicity = 14

The receiver’s detected LEO handover cadence and seconds-to-next-spike, so the sender pre-arms protection one cycle ahead of a periodic delay spike.
