In `@server/scan/presence.py`:
- Around line 28-29: Update current_scan_presence_condition in
server/scan/presence.py to alias the inner CurrentScan relation as
presence_scan, compare presence_scan.scanMac with mac_column, and reject
presence_scan as an input qualifier. In test/scan/test_presence_helper.py,
execute the qualified fragment against one present and one absent MAC and assert
that only the present MAC matches.
In `@test/db/test_schema_drift_guard.py`:
- Around line 53-55: Update _drift() in test/db/test_schema_drift_guard.py at
lines 53-55 to compare normalized column-name-to-declared-type maps from PRAGMA
table_info for the expected schema and _columns_from_ddl output, detecting type
changes as well as missing or extra columns. At lines 139-140, extend the
restored-column assertion to verify its type matches first_type, preserving the
existing column restoration checks.

In `@docs/PLUGINS_DEV_DATA_CONTRACT.md`:
- Around line 208-209: Update the event-flow documentation around “New Device”
so it is not classified as requiring scanPresence = 1. Describe it as a
CurrentScan row event governed by scanCreatesDevice = 1 with a non-blank MAC, or
list it separately from presence-gated events; keep the presence-gated handling
for Connected, Down Reconnected, and IP Changed.
- Line 225: Update the table entry’s explanation of blank-MAC handling to
distinguish the group-level blank-MAC guard from the row-level scanCreatesDevice
= 0 value: the guard blocks the aggregated group, while 0 only prevents that
individual row from originating a device. Remove the claim that both
independently block the MAC.
