docs: the review classifier's try-out service, its key and its subject

Browse source 
- review-classifier.md: claude runs spawn through hive-claude directly
  with no tools and no session (hive-runtime holds only TurnStop); the
  answer's fields, the 500-character reason cap and what a failure does;
  how the try-out page reaches the classifier; the settled parts of the
  open list (API key path, try-out subject, --tools "" on claude).
  The banner stays.
- services.md: a Review classifier section with the two operator steps.
- secrets.md, credentials.md: the classifier's leaf and the key row.
- network.md: the container's row. CLAUDE.md: the crate.

full agent identity, no state directory and no tools. Every model session is
ephemeral, and nothing carries over from one run to the next.
The model sessions run through [`hive-runtime`](../../hive-runtime/README.md),
the crate `hive-agent` and `hive-subagent-mcp` already drive their turns
through: the `Runtime` trait in `hive-runtime/src/lib.rs`, with
`ClaudeRuntime` and `AcpRuntime` behind it. That trait runs turns on a durable
session, and the subagent daemon's claude path
(`hive-subagent-mcp/src/session.rs`) spawns claude directly. A refactor
first moves the cancellable per-turn claude session into `hive-runtime` and
moves the subagent daemon onto it; the classifier builds on that shared seam.
On the claude runtimes, each classification is one `claude --print` the
service spawns through the `hive-claude` crate directly, with no session to
resume, no tools (`--tools ""`), no MCP server (`--strict-mcp-config` and no
config) and an empty directory of its own. A classification needs no durable
session, so the service doesn't use [`hive-runtime`](../../hive-runtime/README.md),
whose `Runtime` trait drives the agents' durable sessions.
The service is `swarm-review-classifier`, and its container is the one
[`services.md`](services.md#review-classifier) describes. It holds no forge
credential: `swarm-controller` reads the PR and sends it along.

The first exists **per hive**, because the path it reads carries a hive name
and every hive runs its own reader. Its subject is
`<deploy.bao.queueAgentCommonNamePrefix>-<hive>`; `swarm.nix` reserves that
composed spelling as a hive name, so nobody can name a hive into another hive's
role. The other five reach a path that names a swarm service rather than a hive,
role. The other six reach a path that names a swarm service rather than a hive,
so one role each is enough and their subjects are the flat
`deploy.bao.grafanaOidcCommonName`, `deploy.bao.otelOidcCommonName`,
`deploy.bao.forwarderOidcCommonName`, `deploy.bao.ciRunnerCommonName` and
`deploy.bao.forwarderOidcCommonName`, `deploy.bao.ciRunnerCommonName`,
`deploy.bao.reviewClassifierCommonName` and
`deploy.bao.forgePublisherCommonName`. The last is the only writer, and the one
leaf two units share: the forge's host holds one store identity for the token it
publishes and the OIDC client secret it reads.

On a host that mints its own PKI, `glue-bao-tls.nix` signs all seven and defaults

that CA out of band and name it here — one file per principal rather than one file
shared by six, which is the whole of what this buys. `swarm-ci-runner.nix`
shared by seven, which is the whole of what this buys. `swarm-ci-runner.nix`
refuses the build wherever the runner runs without its pair, as
`swarm-grafana.nix` does for Grafana. The forge's pair refuses nothing: without

it `swarm-bao-forge-publisher` and `swarm-bao-forge-oidc` render, fail at start
naming both options, and the controller runs without forge access and the forge
without a login source until an operator places the leaf.
On a host without the store, where the forwarder never runs, forgetting one of
the other six isn't a quiet degrade. A hand-configured remote-store hive that

names the hive's own `clientCertFile` and misses a principal's pair has the
build refused, by the module of the reader it missed, naming that pair — see

### Review classifier
The review classifier's try-out service, in a `swarm-review-classifier`
container on the host that sets `deploy.review-classifier.enable`. It doesn't
derive from `allSwarmServices`: every run spends money on an Anthropic API
key, so running one is a decision of its own.
Two steps turn it on:
1. Write the key in the secret store's UI at
`secret/swarm/services/review-classifier/anthropic-api-key`, field
`api_key`. The service reads it on every run, so writing or removing it
takes effect on the next run, with no restart.
2. Set `services.hyperhive.deploy.review-classifier.enable = true` on a host.
It needs neither the forge nor a hive on its host. It reaches the queue and the
secret store by name, under its own `review-classifier` leaf. On a host
without the store, that leaf is the one file to copy, as for the CI runner.
The swarm UI's try-out page drives it through swarm-controller; what a run is
and what it costs are in [`review-classifier.md`](review-classifier.md).
