The three delivery units made /run/swarm-grafana-secrets only after
`bao login` and `bao kv get`, so with the store sealed or unreachable the
bind source was never created by them and a switch could restart the
container without it. Each script now starts with the install, from one
shared `ensureSecretDir`, and the tmpfiles comment says what is true.
The module-eval case asserts the install precedes `bao login` in all three
scripts. docs/swarm/sso.md states that after a reboot Grafana stays down
until the secret store answers.
Part of #4998 (slice 2b: grafana).
The three delivery units still read from bao under Grafana's own leaf, but
now write to /run/swarm-grafana-secrets on the host (tmpfs), which the
container bind-mounts read-only at the same path. Before, they wrote to
/var/lib/nixos-containers/swarm-grafana/var/lib/{grafana-oidc,grafana-admin,
grafana-metrics}/ on persistent disk, where a superseded value stayed after
rotation and went into backups of the container root. Host tmpfiles now
removes the three old files.
Rotation is unchanged: refresh_consumer restarts Grafana (or starts it if it
failed) when a file changes, since Grafana reads each $__file{} once as it
starts. After a reboot the files are fetched again; until the store answers
Grafana stays down, where before it came up on the last copy from disk.
Part of #4998 (slice 2b).
The swarm UI has no switch of its own since it runs wherever the
controller runs; its package option follows it under
deploy.swarm-controller.ui. deploy.swarm-ui.package and
swarm.ui.package stay as renames and warn at evaluation. The flake's
default, the vhost root and the module-eval stub use the new path.
swarm-bao-matrix-oidc still reads the secret from bao under matrix-ctl's
leaf, but now writes it to /run/hive-matrix-oidc on the host (tmpfs), which
the container bind-mounts read-only for tuwunel's LoadCredential. Before, it
wrote it to
/var/lib/nixos-containers/hive-matrix/var/lib/tuwunel-oidc/<id>.secret on
persistent disk, where a superseded secret stayed after rotation and went
into backups of the container root. Host tmpfiles now removes that old file.
clientSecretFile must now lie under /run/hive-matrix-oidc/, the one directory
the container shares; any other value fails at evaluation.
Rotation is unchanged: the ten-minute timer rewrites the file when the value
differs and refresh_consumer restarts tuwunel. After a reboot the secret is
fetched again; until the store answers, tuwunel does not start.
Part of #4998 (slice 4: tuwunel).
swarm-bao-forwarder-oidc still reads the secret from bao under the
forwarder's own leaf, but now writes it to /run/swarm-bao-forwarder-oidc on
the host (tmpfs), which the swarm-bao container bind-mounts read-only for the
collector's LoadCredential. Before, it wrote it to
/var/lib/nixos-containers/swarm-bao/var/lib/swarm-bao-otel-oidc/<id>.secret on
persistent disk, where a superseded secret stayed after rotation and went
into backups of the container root. Host tmpfiles now removes that old file.
Rotation is unchanged: the ten-minute timer rewrites the file when the value
differs and refresh_consumer restarts the forwarder. After a reboot the
secret is fetched again; the file is not pre-created, so until the store
answers the forwarder stays down (LoadCredential refuses a missing source) and
resumes from its journal cursor afterwards. The container now starts after
systemd-tmpfiles-resetup, since the new bind source is made there.
Part of #4998 (slice 3: forwarder).
swarm-bao-otel-oidc still reads the secret from bao under the collector's
own leaf, but now writes it to /run/swarm-otel-oidc on the host (tmpfs),
which the container bind-mounts read-only for the collector's
LoadCredential. Before, it wrote it to
/var/lib/nixos-containers/swarm-otel/var/lib/swarm-otel-oidc/<id>.secret on
persistent disk, where a superseded secret stayed after rotation and went
into backups of the container root. Host tmpfiles now removes that old file.
Rotation is unchanged: the ten-minute timer rewrites the file when the value
differs and refresh_consumer restarts the collector. After a reboot the
secret is fetched again; until the store answers the collector starts on an
empty file and the stores refuse its pushes and scrapes.
Part of #4998 (slice 2a).
swarm-bao-ci-runner still reads the token from bao under the runner's own
ci-runner leaf, but now writes it to /run/swarm-ci-runner on the host
(tmpfs), which the container bind-mounts read-only for the register
unit's LoadCredential. Before, it wrote the token to
/var/lib/nixos-containers/swarm-ci-runner/var/lib/swarm-ci-runner/registration-token
on persistent disk, where a superseded token stayed after rotation and
went into backups of the container root. The container's tmpfiles now
remove that old file.
Rotation is unchanged: the ten-minute timer rewrites the file when the
value differs and refresh_consumer restarts the runner. After a reboot
the token is fetched again; until the store answers, a runner that is
already registered keeps running and only a new registration waits.
Part of #4998 (slice 1).
The dashboard, its API, the swagger UI and the agent routes move to their
own vhost, `swarm.dashboardDomain` = `<hive>.hives.<swarm.domain>`, under
the swarm domain so authelia's session cookie reaches it. `/`, `/api/` and
`/api/docs/` ask authelia through `auth_request`, and authelia's
`operatorsOnly` rule for each hive's dashboard name lets only the admins
group in. The hive domain keeps matrix discovery and redirects every other
path to the new name.
The name rides as a SAN on the hive's own gateway leaf: the per-hive bao
role allows it, and hive-tls asks for it and checks coverage.
HTTP Basic auth is gone: the htpasswd writer and its test, the
`hivectl gateway` verbs and host-socket requests, the `gateway.auth`
options (now a removed-option error), the unauthorized page and the bcrypt
dependency. tmpfiles deletes a leftover gateway.htpasswd, which held
bcrypt hashes at 0644.
c0re hands out dashboard and agent URLs on the new name
(HYPERHIVE_DASHBOARD_DOMAIN), and the swarm controller's hive roster
carries each hive's dashboard name for the swarm UI's hive list.
Closes#3469
swarm-bao-forge-oidc fetched the forge's OIDC client secret from bao and wrote
it to /var/lib/nixos-containers/hive-forge/var/lib/forgejo-oidc/<id>.secret,
on the container's persistent root, where it outlived a bao rotation and was
in every backup of that tree.
Now the fetch writes it to /run/hive-forge-oidc/<id>.secret on the host
(tmpfs, root 0400). The directory is bound read-only into the container at
the same path, and forgejo-sso-source loads it through LoadCredential. A
tmpfiles rule creates the directory at boot, so the bind source always
exists, and removes the old persistent copy.
After a reboot the file is absent until the fetch succeeds, and
forgejo-sso-source fails to start until then; the fetch starts it again once
it writes the file. Logins keep working meanwhile: forgejo holds the secret
in its login-source row.
deploy.forgejo.sso.clientSecretFile (and its old swarm.forge.sso name) is
removed: it only chose where in the container the fetched file landed. The
fetch no longer needs the container's forgejo uid, so it no longer fails on a
fresh host before the container has created its state dir.

mara on #5170: "dont split caps and perms. its all perms. / dont include
the now empty tool groups / nothing set -> default / also add perms to
agent creation screen".
- hive-sh4re: one `Permission` enum (messaging, meta, inbox, execution,
web_tools, manage_root_agent) replaces `ToolGroup` and `Capability`;
`lifecycle`/`forge` are gone. `Permission::default_for` is the default
for an agent the swarm sets nothing for.
- The record is `{ "permissions": [...] }`. Missing key, unset field or
no successful read yet = default; `[]` = none; a failed read after a
good one keeps the last value.
- hive-agent reads its own key every 10s and builds each turn's --tools,
--allowedTools and MCP config (rewritten before every turn) from it;
the subagent daemon reads it on each start/continue. Agents get a
read-only grant on their own key.
- hive-c0re restarts an agent only when its manage_root_agent changes.
The import now merges meta/capabilities.json and meta/tool-groups.json
into one list per agent and deletes both; the "import pending, don't
read" decision is `ImportOutcome::read_allowed`, table-tested.
- swarm-controller: `GET /api/permissions` (names + default) and an
optional `permissions` on `POST /api/agents`, stored before the job is
queued. swarm-ui's create-agent form gets a permissions field.
- Deleted: HIVE_TOOL_GROUPS and its forward to the subagent daemon,
tool_groups.rs, ruth's tool-group seed, the permissions rebuild job
(PermPayload/WritePermFile/perm_change), the dashboard permissions tab
and its stale-entries panel.

swarm-bao-grafana-controller-token logs in to the store with Grafana's
leaf, like its three Grafana siblings, and glue-bao-readers-store-order.nix
already orders it after the store's container and PKI unit. The
services-switch case that pins that ordering did not list it, so dropping
it from the glue would have passed. It is now in the roster, and the count
of readers rendered off the store's host goes from 7 to 8: the unit exists
wherever Grafana does.
credentials.md gets the row for its store path, beside the controller's
forge token.
swarm-bao-grafana-controller-token, on the host that runs Grafana, logs in
to Grafana's API over its socket as the built-in admin (the password
swarm-bao-grafana-admin minted, #5138) and keeps a `swarm-controller`
service account that is an enabled Viewer. It mints a token for that
account and writes it to bao at
swarm/controller/swarm-controller/grafana/token under Grafana's leaf. A
ten-minute timer runs it again. The unit keeps a stored token Grafana
accepts. If Grafana refuses the stored token with 401, or bao holds
none, the unit deletes every token of the account and mints a new one.
Grafana's grant gains create/read/update on that leaf, and the
controller's gains read.
swarm-controller serves GET /api/alerts from Grafana's
/api/prometheus/grafana/api/v1/alerts. It reads the token from bao,
keeps it in memory, and re-reads bao once on a 401. The HTTP client has
5s connect and 15s request timeouts. Any failure is a 503 that names its
cause. swarm-ui gets an /alerts page listing them, built the same way as
the hives page.
This is option (c) on #5129, the operator's choice.
create_agent puts back the caps and inference settings it replaced if a
later store or the job insert fails, so a refused creation leaves nothing
behind for the name. The shared field components take an id prefix so the
create dialog and an open editor never share a DOM id. The queue check now
follows the hive roster check, the 422 is documented, and the copy says
empty rather than closed and that destroy keeps stored settings.
POST /api/agents takes optional limits and inference objects, checked by
the same rules as the two PUT routes before anything is queued and stored
ahead of the job graph. The create form gets collapsed sections for both,
reusing the fields of the detail-panel editors.
The minter parses `Request.agent` with `Ident::parse`, as the controller
does, before it makes a scratch directory, runs `claude auth login` or
touches the store, and answers `Failed` otherwise. The name becomes a
directory name and a store path in the one service that writes every
agent's credentials, so it is checked at this service's own boundary.
The doc states that the `operatorsOnly` authelia rule, not the
controller, keeps the routes to operators, and that a stale version record
waits for a relogin. The env-strip comment says it is defence in depth.
Refs #5268
A new swarm service, `swarm-claude-login`, in its own container on the host
that sets `deploy.claude-login.enable` (defaulted on by `allSwarmServices`
where the host has the minter's store leaf, like the review classifier).
- swarm-ui: an agent card showing "login needed" gets a "log in" button.
Its dialog starts the login, shows the URL claude printed, and takes the
pasted code.
- swarm-controller: `POST/DELETE /api/agents/{name}/claude-login` and
`POST /api/agents/{name}/claude-login/code`, behind the swarm UI's
authelia-gated `/api/`, relay the steps to the minter as requests on
`$SWARM.claude-login.request`.
- swarm-claude-login: runs `claude auth login` over piped stdio with HOME
and CLAUDE_CONFIG_DIR in a per-login scratch dir, scrapes the first
https URL, writes the code to stdin, and stores the `.credentials.json`
at `swarm/agents/<agent>/claude-credentials` with a KV v2 write, a new
version over any earlier one. The scratch dir goes on every exit path; a
login waits 15 minutes for its code.
- hive-agent: while parked in `wait_for_login`, reads that leaf every 30 s
under the agent's own cert and installs it only when its KV version is
newer than the one recorded in `<harness>/claude-credentials-version`.
An equal or older version is never put back, because claude rotates the
refresh token and the stored copy is stale after the first refresh.
- swarm-secret-client: `claude_login` paths and `SecretStore::read_versioned`.
- Credentials: a `claude-login` store leaf minted by glue-bao-tls, a
`swarm-claude-login` policy (create/update on
`swarm/agents/+/claude-credentials`, read on its own queue client
secret), an authelia machine client, and a `--claude-login-client`
grant in the queue's auth-callout responder. The unit runs as a static
system user.
The hive's own web-UI login is unchanged.

The wide diff's context drops from 200 to 25 lines, so a block's
enclosing gate stays in view when it opens within 25 lines above the
change (the forge's own diff carries 3). The fallback note, the doc and
the gate fixture (now 20 lines out, not 47) follow.
A failure reading the changed files (a forge error on a tree or blob, a
truncated tree, a non-base64 blob) or joining the diff task made the PR
read fail, so the review posted no verdict. It now falls back to the
forge's 3-line .diff with "reading the files failed: …" as the note.
render wrote each file's whole diff before wide compared it with
MAX_BYTES. It now writes through a writer that refuses once past the cap,
which stops similar's formatter mid-file, so one huge file costs about
MAX_BYTES of output, not its full diff.
The classifier read the forge's PR `.diff`, whose context is fixed at 3
lines. A block moved into a glue module lost its enclosing gate (a
`config = lib.mkIf …` 13 to 191 lines up in the misfired moves #5199,
#5200, #5201), so the glue restating that gate read as a new condition.
The controller now builds the diff itself: it lists the PR's changed files,
reads each at the merge base and at the head through the git tree and blob
API with the token it already holds, and diffs them with 200 lines of
context. It sends the forge's `.diff` instead when the PR changes more than
100 files, the forge names no merge base, or the wide diff is over 256 KiB,
and the posted review then says so with the reason.

The metrics vhost forwarded the store's read API (query, series, labels,
export, vmui, ...) with no credential, so anything that could reach
metrics.<swarm> could read every hive's and agent's metrics. mara ruled on
checked by an auth_request responder, and operators use their authelia
session.
- swarm-metrics-auth (new crate): auth_request responder on the metrics
store's host. Compares the presented bearer, in constant time, with the
one stored at swarm/services/<grafana client id>/metrics/bearer, read
under its own bao leaf and cached for 60s. Static user, the post-#5264
swarm-logs-auth unit shape.
- swarm-bao-grafana-metrics-bearer: on Grafana's host, creates that bearer
in bao if absent (create without update, Grafana's existing leaf) and
writes "Bearer <value>" into the container; the datasource sends it as
its Authorization header via $__file{}.
- The vhost: read locations take auth_request through a map (a bearer goes
to swarm-metrics-auth, anything else to authelia, no login redirect);
vmui takes an authelia session with the login redirect; forceSSL like
the logs vhost. The authelia subrequest location is renamed from
/__metrics_push_authz to /__metrics_authelia since it now serves reads.
- Authelia: the collector keeps every path; everyone else is refused the
collector's push and /metrics paths; group admins is admitted to the
rest; then deny.
- bao: a swarm-metrics-auth cert role and policy (read on the one leaf),
its leaf minted by glue-bao-tls, the CN reserved as a hive name, and
Grafana's grant gains create on the bearer leaf.

The retries covered about a minute, and the swarm-bao restart that lost
#5286's review lasted 3m19s. Each try now gets its own forge deadline,
a try with no answer by then is retried like a refused connection, and
the waits are 5s, 15s, 45s, 90s and 150s: six tries over about five
minutes.
The docs also said to request the review again after a post-failed run.
That does nothing while the account's earlier request is still pending,
so they now say to remove the request and then request it again.
A review request's verdict was lost when the post failed: on 2026-10-14
the classifier approved #5286, but its post hit swarm-bao mid-restart
(cert login: connection refused), the run was recorded post-failed, and
nothing on the PR showed it.
post() now tries the post up to four times, waiting 5s, 15s and 45s,
when it fails because the connection to the secret store or the forge
failed or timed out. Any other error fails at once, as before. The
verdict is computed once and reposted as is. All tries share the one
forge deadline the single post had, and the warn log carries the number
of tries.
`swarm-bao-pki` was a `RemainAfterExit` oneshot. Once active, nothing
re-ran it: a switch restarts it only when its definition changes, and a
`Requires=`/`Wants=` on an active unit is satisfied without running it.
On muede-lpt2 the 10:57Z switch that added the builder line did change
the unit, so switch-to-configuration stopped it in its stop phase. A
start of `container@swarm-bao` 4 s later (before the daemon-reload at
10:57:35Z) pulled it back in through `swarm-bao-certs` with the OLD
definition, which had no builder line: 48 ms, nothing missing. The start
phase then found it active and did nothing. The 20:14Z switch that
enabled the builder left the unit unchanged, so it was never re-run, and
`container@swarm-builder` crash-looped on the absent `builder.pem`.
The unit now goes inactive after each run. Every switch starts
`multi-user.target`, which runs it again post-reload with the current
definition, and every unit that wants or requires it runs it on its own
start. Each line is idempotent on presence, so an existing leaf is never
re-signed.
The three consumers started from `machines.target` rather than
`multi-user.target` also want it, since `After=` alone does not order
against a job in another transaction: the builder's and the review
classifier's containers (nspawn `--load-credential`) and
`swarm-nats-auth-secrets` (pulled in by the queue's container).
Fixes#5284
A separate $SWARM.control.<agent> subject carries commands, apart from
the text subject. swarm-controller exposes POST /api/agents/{name}/cancel
as a NATS request; the harness answers whether a turn was actually
stopped, through the same cancel path as the dashboard button. The agent
credential gets subscribe on its control subject and allow_responses to
answer; only the controller may publish there.

The review body's table is now: result | check | certainty / threshold |
reason. The result cell is a symbol for what the row did to the review,
after polarity (✅ counted and passed, ❌ counted and failed, ❔ not
counted or no answer), then the model's verdict. The overall line carries
✅ / ❌. Polarity, threshold and counted are folded into those cells.
The prompt asks for a reason under 350 characters; the enforced cap
stays 500, so an overshoot is truncated less often.
deploy.builder.enable defaults on under deploy.allSwarmServices (mkDefault),
where the host has the builder's store identity pair, as for the review
classifier. An explicit false still wins.
The two review tabs, runs and try-out, are one: /review. It is a column of
three sections: try a classification and the classifier settings, each a
folded bar (the settings' bar says what they are now), then the recent runs,
always open. The settings had been pinned under the try-out form; they are now
a section of their own. A new Disclosure primitive is the folding bar, a
native details wearing the Panel's classes, so the folded and open sections
read as the same surface.
/review-runs and /review-tryout are gone, with no redirect.
authelia takes the first matching rule, and a rule with a `subject` does
not match a subject outside it. The swarm domain's and the bao UI's
`group:admins` rules had nothing after them, so an account in no group
skipped them and landed on `default_policy = one_factor`: any
authenticated account reached the swarm UI, its `/api/` (by cookie or by
bearer) and the bao UI.
Each of the two group rules is now an `operatorsOnly` pair: the group
allow, then a subject-less `deny` for the same domain, the shape
`collectorOnly` already gives the collector's metrics rules.
`default_policy` stays `one_factor`, which the forge and chat rely on.
module-eval-swarm-otel-identity gains two cases on `allLocal`: an
account in no group is refused the swarm domain (four paths) and the bao
UI while `group:admins` passes and the forge stays open; and a
predicate, `autheliaSubjectRulesClosed` in lib.nix, holds over the
rendered list: every subject-scoped allow is closed by a later
subject-less `deny` on its domain with no subject-less allow in between,
and nothing follows a domain-wide `deny` on its domain.
Fixes#5120
The agent's turn-state header ($SWARM.agent-state.<agent>) gains
`needs_login`, set by hive-agent from its own LoginState, so the flag
reaches the swarm without hive-c0re (mara on #5268: "id prefer the agent
container sending the info it needs login without hive").
- swarm-queue-client: `agent_login::Login`, the shared wire type, beside
`agent_inference::Effective`. `needs_login: Option<bool>` with
`#[serde(default)]`: a header from an older agent decodes as `None`
(unknown), never as "needs login" or "logged in".
- hive-agent: the header publisher reads the shared LoginState cell.
Every writer of that cell emits a status on the bus afterwards, so a
login change goes out on the next rebuild, not the 60 s refresh.
- swarm-controller: `agent_login::Reported` follows every agent's header
and keeps the latest flag; `GET /api/agents/status` merges it into each
row as `needs_login` (null when unknown).
- swarm-ui: AgentCard shows a warning-tone "login needed" badge when the
row's `needs_login` is true.

/ is now the swarm's name over the digital-rain backdrop the hive
dashboard's home has, and the swarm name in the header links to it. The
hive directory moves to /hives, where the nav's hives tab points. The
swarm name is read once per page load by a shared hook, the header and
the start page both use it. Closes#5252
The commit author's email was the forge account's own address, read with
the site-admin token, which put an email the account may keep private
into the target repo's history. It is now the address Forgejo itself
uses for such an account's web commits, `<lowercased login>@<NO_REPLY_ADDRESS>`
(models/user/user.go GetPlaceholderEmail). NO_REPLY_ADDRESS defaults to
`noreply.<DOMAIN>` (modules/setting/service.go) and the forge module
leaves it unset, with DOMAIN set from services.hyperhive.swarm.forge.domain,
the same option SWARM_CONTROLLER_FORGE_URL is built from; so the domain is
that URL's host. The account is still read, to refuse a user with no
forge account, but its email no longer is.

The try-out page gets an "open a PR" button. It posts the page's
classifications to the new POST /api/review-classifier/open-pr, which
merges them by name into the repo's rules file on the default branch
and has the review-classifier forge account commit the result on a new
branch, review-classifier/<user>-<8 hex>, through the contents API. The
commit's author is the forge account named like the session's
Remote-User, read with the controller's admin token. The answer links
to the forge's compare page, where the user opens the PR as themselves.
The push uses the account's existing token from the store
(swarm/services/review-classifier/forge/token, scope write:repository),
so the account needs write access to the repo; a refused push answers
403 naming that. In a YAML rules file, the entries the merge leaves
alone keep their text, as long as the result reads back as the merged
list; otherwise the file is written out whole.
DefaultBranchFiles now carries each file's blob sha, which the forge
needs to replace a file, and the repo's web URL for the link.

On the API key runtime the classifier now hands claude its prompt as one
stream-json user message (`--input-format stream-json`) with two text
blocks: the PR's shared context, carrying `cache_control: ephemeral`, and
the classification's question.
As plain stdin text the whole prompt was one block, and claude puts its
only message breakpoint on the last block, after the question. The cache
writes an entry only where a breakpoint is, so no entry ended at the
shared-context/question boundary. Every classification wrote the whole
prompt and none read it (production: cacheRead ~0, cacheCreation ~input).
The system-prompt prefix (~270 tokens) is under the minimum cacheable
length. Captures against a local listener with a dummy key (claude
2.1.223) show the client breakpoint survives on the shared block, and that
claude adds none there on its own.
The PR stays in the user role: moving it into the system prompt would give
untrusted PR text the system prompt's authority.
`Model::ask` takes a `Prompt { shared, question }`. The ACP runtime joins
it back into the same text it sent before.

The metrics store's container gets privateNetwork = true with no
interface but loopback. VictoriaMetrics listens on
unix:/run/swarm-victoriametrics/victoriametrics.sock, a host directory
(root:nginx 0770) bind-mounted into the container, and every vhost
location that forwarded to 127.0.0.1:8428 now forwards to that socket.
The store runs as a static user whose primary group is nginx's gid,
with UMask 0007, so the socket it creates is 0770 group nginx. This
relies on VictoriaMetrics >= 1.153.0 honouring the umask (the locked
nixpkgs ships 1.153.0). nixpkgs' readiness loop curls a TCP URL, so
postStart is replaced with the same loop over --unix-socket.
swarm.victoriametrics.port is removed (nothing binds it any more), with
a mkRemovedOptionModule entry, and dropped from swarm-otel's host
port-collision assertion. The container's resolver unit is dropped:
there is no interface to reach the bridge resolver through, and the
store resolves no names.
The collector scrape, the collector push and Grafana's datasource
already reach the store by its published domain, so they are unchanged.

The classifier settings page showed model and effort only, so the API-key
or ACP runtime could be switched only through a raw API call. It now has a
runtime select, and under ACP the provider's URL, model and prices. A PUT
carries the provider only on the ACP runtime, so the stored record stays
for a switch back. Closes#5249
The daemon's two-minute refresh compared the store's linked account
names with the names it booted with. A secondary that was named but did
not come up - no token at bring-up, a token the homeserver rejected
(M_UNKNOWN_TOKEN), or a homeserver still down after the ~52 s boot
retries - kept its name in the set, so nothing ever noticed it again:
it stayed down until the daemon restarted for some other reason, and
an operator re-linking a rejected account changed no name.
Each such secondary is now tried again on the same two-minute period,
one per tick, after one refresh and then doubling waits capped at
sixteen minutes. One that comes up joins the registry (now behind a
lock) and its sync loop joins the running set; the primary and the
other accounts are not restarted. The store is still only read.
The startup todo wipe moves out of bring_up_account to run once before
any sync loop: run per account, a late secondary would have cleared the
todos the running accounts' sweeps had already deduped.
