Atomic transaction: check the signing key against the tenant’s trust list (the signingKeyRegistry binding), verify the Ed25519 signature over the canonical envelope, read the image’s /app/index.json and verify it hashes to the signed indexHash and names the signed artifactVersion (ImageRegistryBinding), validate every tool / guardrail / agent / flow it declares (the image’s index is what registers; the request carries none), upsert into the corresponding registries (in the body’s projectId, one project per client, else the tenant’s Default project), then record the deployment. All-or-nothing rollback on any failure. Idempotency: same imageDigest re-submitted returns 200 with the existing record (no new version bump). Idempotency-Key also applies at the HTTP layer.

Idempotency-Key
string
>= 1 characters

Caller-supplied idempotency key, scoped to the caller: the same key from someone else in the tenant is their own request (from 0.1.5). Retries with the same key return the original response byte-identical (per docs/API-ROUTE-CONVENTIONS.md §3.1). A retry sent while the first request still runs is answered 409 idempotency-key-in-flight with Retry-After, on a runtime whose store holds keys (from 0.1.5); retry after it, and you get the first request’s answer. An answer that carries a secret (a new API key or public run token, a session token, a generated signing secret) isn’t kept: a retry gets 409 idempotency-key-replay-withheld, with the first request’s status and when it succeeded (from 0.1.5).

Media typeapplication/json

Full digest-pinned OCI reference: <host>/<repo>@sha256:<hex>.

string

required

Issuer-generated YYYYMMDD.N — covered by the signature.

string
/^\d{8}\.\d+$/
indexHash
required

Sha256 of the image’s /app/index.json, byte for byte — covered by the signature. The server reads the file from the image, checks it hashes to this, and registers what it declares.

string
/^sha256:[0-9a-f]{64}$/
signerKeyId
required
string
>= 1 characters
signerPublicKey
required

PEM-encoded Ed25519 public key (-----BEGIN PUBLIC KEY-----\n…). Parsed to raw bytes for verification.

string
signature
required

Base64 of the Ed25519 signature over canonicalise({ imageDigest, artifactVersion, indexHash, tenantId, publishedAt }) with sorted keys, no whitespace, UTF-8.

string
publishedAt
required

Issuer-supplied ISO-8601 timestamp — covered by the signature.

string format: date-time
projectId

The project to deploy into, one per client: its agents, flows, tools and guardrails are registered there, and its secret sync writes there. It takes admin on that project (a key limited to another project is refused). Absent: a tenant-wide deploy, into the tenant’s Default project. An id that already lives in another project is 409 (tool-project-mismatch and the like): each client gets its own pack, whose ids carry its own pack id. Not covered by the signature, which attests the image.

string format: uuid
endpoint

Its pack service’s status, when the server routes each pack call to the deployment that shipped the tool (KINDGI_PACK_ROUTING=per-deployment). Absent otherwise. pending: no pack service yet, and calls to its tools fail (pack-endpoint-pending) rather than go to another deployment. ready: calls go to its own pack service. cleared: its pack service was taken down, and calls fail (pack-endpoint-cleared). Carries no URL and no token.

object
code
required

One of a fixed list; a later runtime may add codes, so treat an unknown one as a reason not yet named. The server refused the endpoint it was given: endpoint-url-invalid (not https, or with user info or a path), endpoint-host-not-allowed (the host isn’t on the operator’s allowlist), endpoint-name-mismatch (the host doesn’t name this deployment’s service), endpoint-unreachable (the pack service didn’t answer), endpoint-info-mismatch (it answered as another pack or version), image-not-allowed (the image is outside the tenant’s repository). The pack service couldn’t be created: tenant-not-provisioned (the tenant has nowhere to run pack services yet), capacity-unavailable (no room for another pack service just now), service-start-failed (the image was deployed but didn’t start).

Signature invalid, image unverifiable, or deployment-validation-failed with per-primitive details[]. A tool that declares or sends a model provider’s key is one such issue (path /secrets/<name>): a tool never gets a model provider’s key. A tool whose metadata has a key under kindgi. (the runtime’s own) is a validation-failed detail at /metadata/<key>. Or reference-out-of-scope: an agent or flow names a tool, agent, flow, guardrail or data block that neither the deployment brings nor its project reaches (details.issues, at /agents/<i>/… or /flows/<i>/…); nothing is registered.

Idempotency-Key was reused with a different body, or resource-state conflict. Or, on a runtime serving many tenants (KINDGI_TENANCY=multi), where each tenant deploys only its own images: image-not-allowed, the image is outside the tenant’s repository (details.imagePrefix, its own), or image-prefix-unset, the tenant has no repository set yet; both are checked before any registry read, and never on a runtime serving one tenant. Or tool-project-mismatch, agent-project-mismatch or flow-project-mismatch: one of the image’s tools, agents or flows belongs to another project (details.primitive, details.id; the message doesn’t name the project); nothing was deployed, even when it was unchanged. Or project-suspended: the project the deploy goes into (the named one, or the Default for a tenant-wide deploy) is suspended, and nothing deploys into it until it’s restored. Or registry-read-only: this registry takes no writes (under kindgi dev, the pack’s files are the source); the message says what to do instead.
