§12's monthly cycle drains a pack to empty and refills it to true its coulomb
counter. There was exactly one `Maintenance` and one un-namespaced history, so
at two packs only the first was ever recalibrated - and nothing prevented the
cycle draining pack A while the loop charged pack B, which is two power-moving
phases on one grid connection pulling against each other.
* ONE `Maintenance` PER ROSTER ENTRY, each with its own schedule, phase and
history under `unit/<name>/...`. `store.migrate_maint_keys()` moves an
install's flat history into the first pack's namespace under
`migrate_unit_keys()`'s three rules - shared in code via `_move_flat_keys()`
and `_verify_moves()`, not restated - on its own marker, because unlike
DEV-02's it runs only where the roster has more than one pack. The flat keys
are kept LIVE as the rollback view.
* ONE MAINTENANCE SLOT PER SITE (`maintenance.arbitrate()`). At most one pack
in a power-moving phase - drain, charge AND hold. The holder is DERIVED from
the packs' own stored phases, never persisted, so a restart mid-drain
re-derives it. Several packs due in the same hour: the slot goes to the one
that has gone longest without a completed cycle; roster order breaks a
numeric tie and nothing else. Nothing preempts a cycle in flight.
* THE DEFERRED PACK IS NOT STARVED AND IS NOT A FAULT. A deferral does not
stamp `last_start_attempt` and does not move the phase, so neither the 12 h
drain nor the 36 h charge timeout is reachable by waiting.
* The claim is filed on the pack whose state machine produced it, and stays
SCOPE_UNIT - ARCH-01's rule.
* `validate.py` rule 6 grades `maintenance_charge_w` against the WEAKEST cap on
the roster now, as its own comment said it must once `maint_unit` stopped
being `inverters[0]`.
* At a roster of one nothing changes, and it is asserted: no new store key, the
migration does not run, the four cycle events are the shipped strings, the
banner is the bare phase.
* RECORDED NOT FIXED: a drain pins its pack while the loop's target is a site
claim, so below the pin the allocator refuses the split and the site parks at
0 W. Pre-existing at 2d025ee. Pinned as a running check.
Verified: 19/19 suites green in the CI image; 17 mutations run through
tools/mutation_run.sh (bytecode purged), every one observed red.
