Every hive's homeserver loaded a per-hive `hyperhive` appservice
registration, and the swarm minted and delivered an as_token for it
through bao. No client presented that token: swarm-controller creates
every `@hive-<hive>` sender and every agent account with the swarm
appservice token (hive_sender.rs, agent_token.rs), and no Rust code read
the per-hive one.
Removed, with everything that existed only to serve it:
- hive-matrix.nix: the `hyperhive` registration, its activation-time
render, the host bind mount of /var/lib/hyperhive/matrix-appservice,
its LoadCredential entry, and the internal options
`deploy.matrix.appserviceTokenFile` / `appserviceRegistrationScript`.
tuwunel now loads only the swarm registration.
- glue-matrix-bao-token.nix and its `swarm-bao-matrix-token` unit.
- glue-bao-tls.nix: the matrix-token leaf and its defaults.
- swarm-bao.nix: the `swarm-matrix-token-<hive>` roles and policies
(`swarm-bao-matrix-token-policy`), and the options
`deploy.bao.matrixTokenClient{Cert,Key}File` and
`matrixTokenCommonNamePrefix`, now mkRemovedOptionModule.
- swarm-secret-publisher.nix: the per-hive token mint and its state dir.
- swarm.nix: the reserved `<matrixTokenCommonNamePrefix>-<hive>` CN.
- swarm-secret-client: `matrix::appservice_token_path`.
The swarm registration (swarm-matrix-ctl, swarm-controller) is untouched.
Comments and docs that pointed at the removed glue file now point at
glue-queue-agent-credential.nix, which has the same reader shape.
Refs #4428
Renames `swarm-matrix-minter` and reshapes it around subcommands. Minting
is now `swarm-matrix-ctl mint`.
Running rust inside `containers.hive-matrix` is not free: it needs its own
store identity, its own cert role and its own bind mounts, and every one of
those is per-*container*, not per-task. A second single-purpose crate would
have had to duplicate that plumbing to add one action, so the next thing
that has to run in there should be a verb here rather than a new crate.
The old name guaranteed the opposite.
`main.rs` is clap dispatch; the minting logic moves to `mint.rs` unchanged.
A bare invocation is refused: `mint` writes a credential, so "no verb"
defaulting to it would make a typo in the unit mint rather than fail.
The environment prefix moves with it, `MATRIX_MINTER_*` → `MATRIX_MINT_*`.
Scoped to the verb and not to the binary, because a binary-scoped prefix is
one the next verb has to share or widen, and a widened one never narrows
again. A test asserts every variable carries the verb's prefix.
The principal renames too. The cert role, bao policy, granting unit, leaf
filename and `certAuthCns` entry all have to spell one string the same way,
so leaving them as `swarm-matrix-minter` would have rebuilt the naming
split this branch exists to remove. Renaming the nix options alongside is
free here: every one of them is introduced by this PR and has never been
released, so no operator config names them yet.
`ExecStart` now names the verb, which is a contract between a nix string
and a clap enum that fails at deploy time with no local signal. Both ends
assert it: `mint_is_spelled_the_way_the_unit_invokes_it` in the crate, and
a new module-eval arm reading the rendered `ExecStart`.
docs/getting-started/setup.md drops the sender token from its "live on the
host" list: setup does not touch this credential, so a setup guide has no
reason to name it.
