First chunk of #589 v0 phase A: plumbing the hive-qualified
'name@hive' form through the per-agent surfaces that the harness
itself owns. Broker from/to + dashboard rendering + container_view
follow in subsequent PRs once damocles ships the HYPERHIVE_HIVE_DOMAIN
env var in harness-base.nix.
- new hive_ag3nt::identity module: label() / hive_domain() /
qualified_label() / qualify(label). Reads HYPERHIVE_HIVE_DOMAIN
(set by hive-c0re.nix module from hyperhive.domain) — when unset
or empty, qualified_label degrades to just the short label so
existing single-hive deployments are unchanged. Six unit tests
cover the set / unset / empty / arbitrary-label paths.
- prompt::render gains {qualified_label} substitution alongside
the existing {label}. system.md template uses both: the agent
intro now reads 'You are hyperhive agent iris (qualified:
iris@darkest.space) in a multi-agent system. ... When you're
talking to or about a peer on a different hive, use the
qualified form (name@hive) so the operator + the manager can
disambiguate'. Manager flavor gets the same treatment.
- /api/state gains qualified_label: String. Always present, equals
label when no domain is configured.
- frontend setHeader takes the qualified_label, drives the browser
tab title (so two tabs from different hives are
distinguishable in the tab bar) while the glyphic #title stays
short for the cinematic header.
Gated on env var presence — no behaviour change for single-hive
deployments. Pairs with damocles's upcoming harness-base.nix
HYPERHIVE_HIVE_DOMAIN ship; safe to land in either order.
