The matrix, forge and github link routes wrote their credential
unconditionally, so linking a name that was already linked replaced the
working account. For matrix that lost the device the agent's crypto store
belongs to (#4838).
Each route now reads the account's store path first and answers 409,
naming the existing account, when something is stored there. Nothing is
written. Replacing an account takes the delete from #4899, then a link.
The matrix route checks before password mode's login, so a refused link
mints no new device at the homeserver.
The check is a read then a write, not an atomic step; two concurrent
links to one name can still both pass it.
Closes#4856
GET /api/hives/{hive}/agents/{agent}/linked-accounts returns one row per
account linked to the agent, as kind, name and host: each matrix account
under swarm/agents/<agent>/matrix (with its homeserver, and the agent's own
`main` marked reserved), each forge label under swarm/agents/<agent>/forge
(with its url), and github when swarm/agents/<agent>/github-token exists
(host github.com, which is not stored). No credential field is in the
response type.
Listing those two directories needs a new controller grant: `list` on
secret/metadata/swarm/agents/+/matrix and .../+/forge only, pinned in
bao-grants.nix as the only metadata stanzas under agents/ beside the queue
revocation. Checked against a dev OpenBao 2.6.3: the grant lists those two
directories and is refused on agents/, agents/<agent>/, and a leaf.
The swarm UI agent detail panel shows all rows under "accounts"; the table
view's matrix column shows the matrix rows. The link badges stay.
Refs #4855
- docs/web-ui/README.md: drop the removed Credentials tile from the
H0M3 hub list.
- api-error.ts, hive-warn.js: rewrite comments pointing at
dashboard/src/credentials.js and credentials.html, now deleted, to
state what the code does instead.
- swarm-secret-client/src/github.rs: correct the Credential.value doc
to the actual read command (bao kv get -format=json | jq
.data.data.value), keeping the load-bearing-field-name point.
- github-token.nix, agent-github-bao.nix, LinkGithubAccountForm.tsx:
restate added comments as current behaviour instead of changelog
wording ("has always had", "holds the token now").
Refs #4347
An operator links an agent's GitHub personal access token in the swarm UI
(LinkGithubAccountForm, "link github account" on /agents). swarm-controller's
PUT /api/hives/{hive}/agents/{agent}/github-account stores it at
swarm/agents/<agent>/github-token (swarm_secret_client::github), a flat leaf
under the agent's prefix that the agent's existing read grant already covers:
no policy change, and no list grant, since there is one token per agent.
In the agent, hive-agent-github-token (oneshot + 2-minute timer, as the agent
user, under its own store certificate, ordered before hive-github-notify)
reads that path and writes <state>/github-token, 0600 and agent-owned, the
file the gh wrapper, git credential helper and hive-github-notify already
read. It replaces the file by rename only when the bytes changed and never
deletes it: a hive-written github-token stays until a token is linked in the
swarm UI. It is installed only with a store address and
services.hyperhive.agent.github.enable.
Removed: the dashboard's CR3D3NTIALS page (credentials.html/js/css, its
build entries and H0M3 tile; GITHUB was its only tab), hive-c0re's
dashboard/matrix_accounts.rs with GET/POST /api/github-account,
priv_client::write_agent_github_token, the host socket's
SetAgentGithubToken and `hivectl github set-token`, and hive-priv's
WriteAgentGithubToken with write_agent_state_file, its only caller gone.
Docs: integrations/github.md and swarm/ui.md describe the swarm path,
swarm/credentials.md gains the store-path row, and the hive UI docs,
hivectl docs and security.md's hive-priv table drop the removed pieces.
Closes#4347
