One attrset describing every hive in the swarm including this one,
identical on every host, with hiveName selecting which entry is us.
"My peers" is derived (swarm.peerHives) rather than declared.
Every field in the old per-host peer list was intrinsic to the hive it
described, never to the pair -- so the list was a directory each host
kept its own copy of. Beyond the deduplication it removes a bug class:
two hosts could hold different endpoints for the same third hive with
nothing to detect the disagreement.
Drops the per-hive caCert. Trust inside a swarm derives from the swarm
root, which every hive chains to. What that genuinely removes is
trusting a hive whose root this swarm does not own -- a cross-swarm
problem that wants a mechanism of its own, not a field that happened to
work.
The matrix container's certificateFiles block goes with it and could
NOT be migrated: that list is read at build time and the swarm root is
a runtime file (its key must never enter the store), so there is no
build-time name to put there. caCert being a nix path was precisely
what made it the build-time distribution channel. Agents are unaffected
-- hive-tls folds the root into the hive trust bundle and the meta
renderer embeds that one file. Tracked separately.
Migration is an assertion plus warnings, not a rename: hives is peers
union {self}, and the set gains a member no existing config has written
down. A rename migrates a name and a default can re-root a meaning;
neither can conjure a new member. The warning explains, the self-entry
assertion stops the build.
`docs/swarm.md` becomes `docs/swarm/README.md` and the shared-services
material moves to `docs/swarm/services.md`, following the shape
`docs/turn-loop/` and `docs/web-ui/` already use. The README keeps a
pointer so the reading path is unbroken.
Every referrer moved with it — five docs pages, two option descriptions
in swarm.nix, and CLAUDE.md's reading path. A pointer to a file that
moved is worse than one to a file that was deleted: the content still
exists, so the reader concludes the note is wrong rather than the path.
docs/tools/hivectl-cli.md is generated by `hivectl markdown-docs` and
diffed against a fresh run by the hivectl-docs flake check, so adding
the push verb without regenerating it would have failed CI. The
regeneration also retires two copies of a sentence describing the
cross-hive leg as an ssh pipe that "isn't wired up yet" -- ssh was
dropped when the WireGuard mesh became the authentication, and the leg
is wired up now.
snapshot-store.md documented only the receiving host, so a reader had
no way to learn how a pushing hive is told where the store is. It now
covers services.hyperhive.swarm.snapshotStore, including why address
has no default and port does: an address is a deployment fact that
cannot be guessed, a port is a convention both ends read from the same
docs. It also states the namespace rule the two options illustrate --
swarm.* describes the swarm as seen from here, a bare
services.hyperhive.<service> describes a role this host performs.
swarm.md never mentioned the store even though the option lives in its
namespace, so a reader configuring swarm.peers had no signal it exists.
Reverting the namespace move from the previous commit — mara's reason
is better than mine was.
I grouped it with swarm.peers and swarm.wireguard because the module
serves the swarm tier. But those two describe THE SWARM: who is in it,
how it is meshed. snapshotStore describes THIS HOST'S ROLE. On a
standalone store box the operator enables one service, and nesting it
under `swarm` implies they are configuring a swarm when they are not.
The swarm- prefix on the file and units stands: the name says which
tier the component serves, the option path says what you are turning
on. Those are different questions and they are allowed different
answers.
mara, in preparation for the swarm tier: the store is a swarm-level
role, not a hive one, so hive- was misleading about which tier it
belongs to. Module, units, syslog identifier, log lines and docs all
move to swarm-snapshot-store.
Also moved the option under services.hyperhive.swarm.snapshotStore, to
sit with swarm.peers and swarm.wireguard rather than dangling off the
top level. That is a judgement call beyond the literal rename — flagged
on the PR, and cheap precisely now: the option has never shipped, so
there is no deployment to migrate, whereas doing it after a release
would be a breaking change for no new benefit.
mara: the option was the wrong shape for the concern. "this host runs
nothing else" is a deployment expectation, not something a module
should assert about its own host — and asserting it made co-location
look like a config toggle rather than what it is.
Replaced with docs/snapshot-store.md, which the module had no docs
page at all before: enabling it, why the mesh is the authentication
(cryptokey routing already binds source address to pubkey, so certs
would authenticate the same fact twice and add an expiry), why the
destination is keyed per agent (a per-hive prefix splits an agent's
chain the first time it migrates), what the sender may and may not
choose, why the firewall rule is interface-scoped, what a snapshot
does and does not contain, and what the pull side still needs.
The dedicated-host expectation is stated there as an operational
assumption with its own failure mode — true on day one, quietly false
the day someone notices the box has spare disk — rather than as an
assertion someone flips to false to make the build proceed.
