The access-log scanner and the cross-node merge stored the same IP list in
opposite orders, so neither saw a row as unchanged, and the merge re-read
every preloaded row and re-upserted every attribution row each sync cycle.
All writers now share one canonical encoder (timestamp, then IP ascending),
the first CAS is seeded from the preload, and identical attribution rows are
skipped. A create race between the scanner and node sync now merges into the
winning row instead of dropping the loser's IPs, which on PostgreSQL also
aborted the scanner's whole scan transaction.
Closes#6927
Each enrollment scope owns its panels, ports and temp dirs, so the two run
side by side; the only shared state, the process-global database handle the
harness borrows for setup and for simulating a lost inbound, is now behind a
mutex. On Linux the suite drops from 188s to 95s.
CLAUDE.md now names the fast contract layer (node_contract_test.go, in
make test-go) next to the multi-tick nodee2e layer.
Node sync had no test with two real panels: the single-panel tests either
call the node's controller in-process or hand-set the node-sync scope, so
823db059 shipped a regression no test could see (an admin-token node
dropped every client and enable flag its master pushed).
internal/nodee2e starts a master and a node as separate panel processes
(the DB is a process-wide global, so one process cannot be both) and walks
17 operations per enrollment scope (admin token, node-sync token): adopt,
create/edit on the master, small and bulk attach, client disable, detach,
client delete, inbound disable, traffic pull and reset, node-side delete
mirrored centrally (#6219), master-side delete, node down, node-lost
inbound re-created, create/edit while down, node disabled on the master,
and selected sync mode leaving unselected inbounds alone.
Against the build before 2ffc694a it fails 6 cells for an admin-token node
and 1 for a node-sync one; on main all 34 pass, on Windows and on Linux.
`make node-e2e` builds a stub-dist binary and runs it; ci.yml runs it as
its own job where a SKIP fails the build. Xray is not started, so cells
assert the node's stored state, not traffic through the core.
