feat(protocol): bind the MNP token to the node it is for (E10)

2026-09-26T00:03:50Z

The audience split stopped a member's node credential from opening the hub API. It did not stop the credential being *replayed to another node*: the MNP token carried the member's whole group set and named no node, so a token handed to node A's operator could be presented to node B the member also belongs to. That does not read content on B — the handshake still requires proving node B's group key, which the operator lacks — but it reaches B's pre-proof window and fetches the member's *encrypted* keypair bundle for B (offline-attackable, bounded, audited): a disclosure §2.4 says should not follow from hosting a member on A. The token now names the node it is minted for (a `node` claim = that node's Ed25519 key), and authorize_token refuses one that names a different key. The client already knows the target node's key (from /v1/groups/{id}/nodes) and asks for a token bound to it: POST /v1/nodes/mnp-token takes node_pk, and transport.connect threads it (group-page, the connection pool and rewrap pass n.pk_node; reconnect preserves it). A token that names no node is still accepted, because the hub only mints one for the authenticated requester, so an unbound token grants nothing across accounts — which also keeps non-binding callers working with no churn. Done before deploy, so it folds into the MNP 4.0 flag day rather than needing its own. Docs: §5.2, register E10, MESHBAY_NODE_PROTOCOL.md §6.3. test_handshake.py and test_mnp_token.py hold the binding (a token for node A is refused by node B, accepted by node A; an unbound token still works); red before, green after. common/node/hub suites green.

refactor(node): split ops.py into the ops package

2026-09-24T23:30:47Z

Each section of ops.py becomes a module of meshbay_node/ops/ (core, node_toml, members, chat, groups, roots, files, settings, apps), cut as text; ops/__init__.py keeps the docstring and re-exports every name, so `ops.` is unchanged for every caller. Logger name unchanged. Co-Authored-By: Claude Opus 5.5

refactor(node): run signed operations through a table of executors

2026-09-24T14:45:38Z

_do_admin_response looked each operation up in a 28-branch elif, every branch the same call. The admin cases of the dispatch golden are unchanged. Co-Authored-By: Claude Opus 5.5

refactor(node): dispatch MNP messages through a table

2026-09-24T14:45:38Z

The pre-authentication guards stay explicit code, in the same order and text. After the handshake, a table maps each type to its handler and to whether it runs as a task, the choice each branch made; the three inline blocks become StreamingMixin methods, unchanged. The dispatch golden is identical, including types that are not strings. Co-Authored-By: Claude Opus 5.5

refactor(node): move _dispatch_message out of webrtc_server, unchanged

2026-09-24T14:45:38Z

DispatchMixin in transport/webrtc/dispatch.py, with the pre-proof fetch bound it enforces. The elif chain moves as it is; turning it into a table is the next commit, on its own. Co-Authored-By: Claude Opus 5.5

refactor(node): move the session core out of webrtc_server

2026-09-24T14:45:38Z

SessionCore in transport/webrtc/core.py, last among the bases: state, the data channel, task ownership, the peer registry, sending and teardown. The facade keeps _dispatch_message and WebRTCTransport. Co-Authored-By: Claude Opus 5.5

refactor(node): move operator authority and the admin response out of webrtc_server

2026-09-24T14:45:38Z

AdminMixin in transport/webrtc/admin.py: who the operator is, the signed challenge, signature checks, and _do_admin_response moved unchanged. Co-Authored-By: Claude Opus 5.5

refactor(node): move the operator's group controls out of webrtc_server

2026-09-24T14:45:38Z

GroupOpsMixin in transport/webrtc/group_ops.py: member revocation and unpinning, the group key rotation, apps and their directories with the allow-list, and Search listing. Co-Authored-By: Claude Opus 5.5

refactor(node): move the operator's node controls out of webrtc_server

2026-09-24T14:45:38Z

NodeOpsMixin in transport/webrtc/node_ops.py: status and settings, roster and denylist, roots, hosted groups, reload, scan pacing and transfer limits, with their class-level bounds. Co-Authored-By: Claude Opus 5.5

refactor(node): section headers follow the code they introduce

2026-09-24T14:45:38Z

Three headers stayed in webrtc_server when their sections moved; they now sit above the same methods in blobs.py and admission.py. Two that were only a title over what is now a whole module are dropped. Co-Authored-By: Claude Opus 5.5
