 # there: the WebRTC shape — the one every deployed client speaks — is byte for byte
 # what it was, and no QUIC client ships. Recorded as a MINOR bump for that reason;
 # a deployed QUIC peer would have made it a MAJOR one.

+# 1.0: `index_sync`, `index_delta` and the `handshake_ack` configuration
+# fields now travel **sealed under a GEK-derived subkey**
+# (`meshbay_common.groupbox`), and the handshake negotiates a supported
+# version range instead of writing a `v` nobody reads.
+#
+# **Breaking, on the wire every deployed client speaks**, and there is no way
+# to describe it as additive: an old client sends `index_sync` and gets a
+# message with no `entries`; it reads `ack.enabled_apps`, finds nothing, and
+# applies its documented fallback — "show every app" — rather than reporting
+# an error; a new client against an old node finds `entries` it does not
+# expect and no `ct`. 0.15 stayed MINOR because only the QUIC wire changed and
+# no QUIC client ships; that argument is not available here, and MAJOR is what
+# the project's own rule says. Hub and every node deploy together; the SPA is
+# served by the hub, so a browser picks up the new client on reload.
+#
+# Version negotiation ships in the same flag day rather than after it (phase
+# 15.6): the coordinated deployment is already being paid for, and it is what
+# makes the *next* breaking change cost a refusal message instead of a second
+# flag day. `MNP_MIN_SUPPORTED` in `handshake.py` is the other half.
+#
+# The index at rest, `index_progress` (counters only, never a path — see
+# `groupbox.py` and daemon.py `_push_index_progress`), chat, and file content
+# on the operator's disk are all deliberately unchanged.
