Estimated code review effort: 4 (Complex) | ~75 minutes Merge Risk: 🟠 High · up to The PR adds a privileged dormant-container creation path, but current evidence indicates that unsafe Docker authority and unexpected labels may still be admitted, and concurrent callers could potentially issue duplicate creates if persistence is not atomic. These security and correctness risks should be fixed or explicitly accepted by the responsible owner before merge. Sequence Diagram(s)sequenceDiagram

@coderabbitai review Please perform a fresh independent review of the current exact PR head only: Please focus on one-shot permit consumption, durable reservation/prepared/created ordering, blind-retry prevention, cancellation semantics, exact Docker create payload, dormant-state reconciliation, identity substitution resistance, fail-closed behavior, and accidental authority widening. R4B-B2/start/exec/kill/remove/TTL/output/H6 are explicitly out of scope. |

P1: Reject unadmitted Docker configuration during reconciliation
A container with the deterministic name and copied required labels can also include unverified Docker authority. Examples include bind mounts, device mappings, This is an identity-substitution and authority-widening path on prepared recovery. The reconciliation must fail closed unless the inspected configuration is exactly the admitted create configuration and an explicit safe-default posture. Validate or reject all authority-bearing The review verified the specified HEAD and base. The diff changes exactly the five authorized paths. I found no additional actionable issue in the reviewed one-shot ordering, no-second-POST path, cancellation flow, or prohibited Docker operation paths. I did not execute repository tests in this environment.

- Around line 655-675: Extend the Docker reconciliation checks around the Config
and HostConfig requiredRecord calls to fail closed when unadmitted
authority-bearing fields are non-empty, including Config.User, Env, WorkingDir,
and relevant mount, capability, device, security, namespace, and networking
fields in HostConfig. Use a stable denylist helper that permits only absent or
empty values, while validating Config.Cmd against the admitted arguments if it
is supported. Perform these checks before constructing the observation and
preserve the existing validations for admitted fields.

- Around line 136-162: Add an extra HostConfig injection option to the fake
Docker harness used by inspectBody, merge it into the inspected HostConfig, and
add a Linux-only regression test covering Mounts, Binds, CapAdd, Devices,
SecurityOpt, PidMode, and IpcMode. For each injected field, assert
createDormantAdmission rejects with SandboxDormantCreateIndeterminateError and
that events does not contain store:created.

- Around line 679-684: Update the network validation around networkKeys to
reject any key other than the canonical "none" endpoint without the redundant
length condition, and derive networkAttachmentCount from whether "none" is
present rather than assigning a literal zero. Preserve requiredRecord validation
for a sole "none" entry.
In
`@packages/kodac-runtime/test/kdo-h4-r4b-b1-dormant-docker-create-admission.test.ts`:
- Around line 202-207: Rename the option persistOnLostResponse to
persistDespiteFailedResponse throughout the affected test setup, handling logic,
and assertions so it accurately covers both lost-response and createStatusCode
non-success paths, including the non-201 case.

Docker uses these fields to mask sensitive paths and make paths read-only. A substituted container can retain the admitted name, labels, image lineage, process configuration, resource limits, and network mode while it removes entries from Validate both fields against the Docker safe default posture. The validation must account for the canonical default lists returned by Docker inspect.

Purpose
Implement the canonical H4-R4B-B1 authorization only: consume one exact durable R4B-A sandbox admission permit into one recoverable dormant Docker/gVisor create admission, without starting or executing the workload.
Canonical base
Exact implementation theorem
Crash / retry semantics
The narrow crash window after durable dispatch claim but before actual socket dispatch is intentionally a burned attempt. Safety (at-most-one possible Docker mutation) takes precedence over liveness.
Image lineage and Docker compatibility
R4B-B1 requires an authoritative local image manifest descriptor before dispatch authority. Docker's
Descriptor.digestfrom image inspection must equal the exact admitted OCI digest, and the resulting Docker image ID is carried forward into container reconciliation. If that descriptor is unavailable, R4B-B1 fails before any create mutation rather than weakening source lineage or substituting a Docker image ID for an OCI manifest digest.The created container must then report:
Host-authority negative space
The create payload explicitly disables stdin and image healthcheck execution and admits only the bounded R4B-B1 posture. Reconciliation rejects authority not present in the canonical R3A/R3B theorem, including non-empty or hostile forms of:
Docker
NetworkMode=nonemay report only the canonicalNetworkSettings.Networks.noneendpoint, which is normalized to zero live network attachments. Any other network key fails closed.Key safety properties
Changed paths
Exactly the five paths authorized by canonical #129:
The dispatch fence, image preflight, and Docker mutation/store constructors remain confined to the dedicated R4B-B1 runtime module and are not exported through the package root.
Explicit non-authorizations
