LiveSeeds

What the page's three seed tags carry — `#milpa-live-signals`, `#milpa-live-persist` and `#milpa-live-computed` — merged from the host's own and every view a section declared (greenhouse decisions/0211). The runtime reads ONE tag of each kind per page (`getElementById`), so the host is the only emitter and this is where the merge happens. Merging is by NAME and it is loud: the same signal declared twice with DIFFERENT values is a {@see SeedConflictException} naming the key and both declarers — never a silent last-one-wins, which would make one guest's seed depend on section order. The same name with the SAME value is not a conflict: two declarers agreeing is agreement, not a clash. `persist` is a list of names, so it merges by deduplication and can never conflict. Every declarer is named when it merges (`the panel`, `section «agent»`), which is what makes the conflict message actionable.

public static function empty(): self

Nothing seeded — the three tags are still emitted, empty: one truth, never a missing tag.

public static function of(string $source, array $signals = [], array $persist = [], array $computed = []): self

The seeds one declarer brings, named.

Parameters

public function merge(self $other): self

These seeds plus `$other`'s.

Parameters

Throws

SeedConflictException when both declare one name with different values

public function isEmpty(): bool

True when nothing was seeded at all.
