This test changes
myNodeInfo.my_node_numdirectly and callsapi->available(). It does not callNodeDB::createNewIdentity()orMeshService::nudgeFromNum(), so it would pass even if the new cross-layer wake-up were removed. Trigger the same notification path and assert the transport notification before reading the refreshedmy_info.This test should cover the PR objective to notify an already-connected client through the live notification path.

In `@src/mesh/NodeDB.cpp`:
- Around line 4564-4565: Update createNewIdentity and its callers so
service->nudgeFromNum() runs only after identity persistence succeeds; defer the
notification until AdminModule’s edit transaction commits, and do not notify
when saveChanges() or reloadConfig() fails. Preserve the existing identity
creation behavior while ensuring clients cannot observe the new my_node_num
before SEGMENT_DEVICESTATE and SEGMENT_NODEDATABASE are persisted.
In `@src/mesh/PhoneAPI.cpp`:
- Around line 1694-1695: Initialize the reportedNodeNum baseline when starting
the SPECIAL_NONCE_ONLY_NODES handshake, or track whether MyInfo was actually
sent, so STATE_SEND_PACKETS does not trigger an unexpected my_info after
config_complete_id for normal nonzero node numbers. Update
test_only_nodes_nonce_sends_nodes_then_complete to drain the stream after
completion.
In `@src/mesh/PhoneAPI.h`:
- Line 87: Remove reportedNodeNum from the PhoneAPI object to preserve its
layout and size. Store the value in the existing file-scope per-connection
state, and update the resend logic to read and write that shared state instead.
In `@test/test_phone_api_config_dump/test_main.cpp`:
- Around line 228-231: Update drainToIdle to loop while i is less than maxReads,
ensuring the read cap is not exceeded, and replace the default literal count
with a named test-limit constant.

The first region set mints the PKI key and moves my_node_num to crc32(public_key) live. my_info only went out during the want_config_id handshake, so an already-connected client kept addressing the old number and its admin packets NAKed PKI_SEND_FAIL_PUBLIC_KEY until it reconnected. PhoneAPI tracks the number it last reported and re-sends my_info from STATE_SEND_PACKETS when it no longer matches. createNewIdentity() nudges fromNum so clients poll. Fixes #11718
Review follow-up. The per-connection reportedNodeNum field is gone: adding per-instance members to PhoneAPI is documented as breaking USB-CDC enumeration on the nRF52 Adafruit framework, and the baseline was never set for SPECIAL_NONCE_ONLY_NODES, which skips STATE_SEND_MY_INFO and so emitted an unexpected my_info after config_complete_id. MeshService::identityMoved is set with the nudge and cleared once the notify pass has reached every observer, so PhoneAPI::onNotify arms STATE_RESEND_MY_INFO on each connected client in that single pass and stores nothing per connection. The test now drives NodeDB::createNewIdentity() and MeshService::loop() instead of writing my_node_num directly, and asserts the transport wake-up. Nodes-only sync asserts no trailing my_info. drainToIdle() honours its read cap.
Review follow-up. A client still in its config dump has already been sent the old my_info and has no steady state for the one-shot to fall back from, so the notify pass cleared identityMoved without covering it and the client finished syncing on the obsolete number. PhoneAPI::onNotify now restarts such a client's dump, which is the existing re-handshake path. Skipped for a client that has not reached my_info yet and for SPECIAL_NONCE_ONLY_NODES, which never sends one. test_node_num_change_mid_dump_restarts_sync renumbers mid-dump and asserts the restart, the new number, and that no part of the config is lost. Verified to fail without the fix.
…ify pass Review follow-up. The identity move can run off the loop task: a local admin set_config reaches AdminModule through Router::sendLocal() on whichever task delivered it. A bool cleared by MeshService::loop() could therefore be set and cleared without any client being armed, losing the re-announce. A generation counter replaces the bool. loop() snapshots it with fromNum before notifying and only advances the seen counter afterwards, so anything bumped during the pass is still pending. The same snapshot fixes a notify for a fromNum bump that arrived mid-pass being marked delivered. test_node_num_change_mid_dump_restarts_sync now asserts the whole restarted dump: header order, channels, both config sections, our node record, nonce. Also trims the MyInfo redaction comment to the two-line cap.
…s-only syncs Review follow-up. createNewIdentity() removed our old row and appended the new one, leaving index 0 pointing at some other node. PhoneAPI's own-nodeinfo read and the demote/evict scans that skip index 0 to protect us both rely on that slot being self, so a renumbered node handed every client a stranger's record as its own. Pinned the way nodeDBSelfCare() does it. onNotify no longer exempts SPECIAL_NONCE_ONLY_NODES from the mid-sync restart. That dump carries no my_info, but it does carry the self record, which the move invalidates the same way. Such a client also gets the re-announce once its sync lands in STATE_SEND_PACKETS, which it previously never did. The generation counters are atomic. Every interleaving was already safe, since observers read the live counter and the seen counter only advances to a pre-pass snapshot, but the concurrent plain accesses were a data race on paper.
Review follow-up. The counter is bumped from whichever task queued the packet and read by loop(). It is private to MeshService, so the type change covers every access.
