Do not latch full on transient zero current; require explicit completion. Validate go-e errors and Pico status/timestamps, keep historical events diagnostic, and preserve faults until a fresh successful poll. Budget the 6 A phase probe through the manager and correct stale phase counts conservatively.
Add adapter, regulator, isolated runtime and Symcon regression cases plus migration documentation. Verified: composer check (402 tests, 1875 assertions), 92 pure-function assertions in Symcon 8.0, git diff --check. No plant deployment or hardware commands.
