+## NemoCUA Runtime Qualification
+
+NemoCUA runs as a standalone terminal agent inside one NemoClaw-managed OpenShell sandbox.
+The image release lane consumes the exact inputs in `agents/nemocua/runtime-artifacts.json`.
+The release lane must verify each SHA-256 identity before it stages or builds an image.
+
+| Input | Version | Platform or file | SHA-256 identity |
+|---|---|---|---|
+| NemoCUA host CLI | `0.0.20-dev-v3` | `nemocua_linux_amd64.tar.gz` | `702d93c4fc01ba4aafdd23daaf17fd25cea8f7deab3f1caa1c91ef047f4778aa` |
+| NVLumina sandbox image | `v0.0.5` | `linux/amd64` | `sha256:c1a577fc8f69071642b97706130df26abd8a89b8bd429a9ef37abf0ccd634e0b` |
+| NemoCUA target services | `0.0.66-dev-v29` | `nemocua-services-linux-x86_64-v0.0.66-dev-v29.tar.gz` | `6d731e02226b364daa61d3521e5903b86f1e4260e41d330b1a7daed5c3ae3b01` |
+
+
+The checked-in artifact manifest currently reports `awaiting-live-qualification` for issue `#7755`.
+Onboarding therefore fails closed during agent setup and does not record available CUA runtime readiness.
+The public CUA lifecycle commands return `lifecycle_unavailable` until the exact tuple passes live qualification and the manifest reports `qualified`.
+
+
+Before onboarding, set `NEMOCLAW_NEMOCUA_RUNTIME_IMAGE_REF` to an accessible image reference that ends with the declared `@sha256:` digest.
+NemoClaw rejects a mutable tag or a different digest before it builds the base image.
+It passes the verified reference as the `NEMOCUA_RUNTIME_IMAGE` build argument for `agents/nemocua/Dockerfile.base`.
+The final image adds the `nemocua-runtime` wrapper and the content-free artifact manifest without adding a second sandbox lifecycle.
+
+Select the NemoCUA agent manifest during onboarding with the following command:
+
+```bash
+NEMOCLAW_NEMOCUA_RUNTIME_IMAGE_REF="@sha256:c1a577fc8f69071642b97706130df26abd8a89b8bd429a9ef37abf0ccd634e0b" \
+ $$nemoclaw onboard --agent nemocua --name my-cua
+```
+
+The same `--agent nemocua` selection works with interactive or non-interactive onboarding.
+NemoClaw builds the agent image, checks `nemocua-runtime smoke`, requires version `0.0.20-dev-v3`, and probes the managed inference route.
+It records CUA runtime readiness only after the pinned release tuple has passed live qualification.
+
+The wrapper exposes these in-sandbox commands:
+
+```bash
+nemocua-runtime interactive
+nemocua-runtime headless "Complete the assigned desktop task"
+nemocua-runtime version
+nemocua-runtime smoke
+```
+
+`interactive` runs `/app/run.py` in the existing sandbox.
+`headless` runs `/app/run_with_harness.py` with a generated task ID and a private runs directory under `/sandbox/.nemocua`.
+`version` checks the required runtime files before it prints the pinned wrapper version.
+`smoke` checks the runtime files and the managed `https://inference.local/v1/models` route.
+
+Use `$$nemoclaw exec` when a host process needs to run one wrapper operation directly.
+
+```bash
+$$nemoclaw my-cua exec -- nemocua-runtime version
+$$nemoclaw my-cua exec -- nemocua-runtime smoke
+```
+
+The public host CUA lifecycle maps to the operator-owned adapters as follows:
+
+| Lifecycle operation | Public host command | Host adapter behavior |
+|---|---|---|
+| Attach target | `$$nemoclaw my-cua cua target attach --adapter --target-manifest ` | Creates or obtains target authority, probes the declared services, and returns a target attachment record. |
+| Read target status | `$$nemoclaw my-cua cua target status` | Reads the content-free registry projection without invoking an adapter. |
+| Detach target | `$$nemoclaw my-cua cua target detach --adapter ` | Revokes target reachability and returns a detached record. |
+| Verify security | `$$nemoclaw my-cua cua security verify --adapter ` | Verifies the current policy and isolation boundary and returns a content-free attestation. |
+| Read security status | `$$nemoclaw my-cua cua security status` | Validates the recorded attestation without invoking an adapter. |
+| Start task | `$$nemoclaw my-cua cua task start --adapter --task-id --mode --input-file ` | Starts the task through the declared task protocol and returns active task state. |
+| Read task status | `$$nemoclaw my-cua cua task status --adapter --task-id ` | Returns active state or the retained terminal result. |
+| Read task result | `$$nemoclaw my-cua cua task result --adapter --task-id ` | Returns and validates the terminal task result. |
+
+
+CUA adapters run on the host and control a separately managed desktop target.
+They must not invoke `nemocua sandbox create` inside the NemoClaw sandbox.
+NemoClaw remains the lifecycle authority for the OpenShell sandbox, and `nemocua-runtime` invokes the installed `/app` runtime directly.
+
+
+## CUA target lifecycle
+
+These commands attach one CUA sandbox to one dedicated disposable desktop target.
+The target must expose `browser`, `computer`, and `terminal` services.
+The operator-owned adapter probes those services and returns their health in a lifecycle record.
+NemoClaw validates that record, compares the immutable identities, and requires all three services to report healthy before it records the attachment.
+
+Every target command also requires canonical CUA runtime-readiness state for the sandbox.
+Until canonical onboarding records an available runtime, the commands return `lifecycle_unavailable`.
+
+Target provisioning stays outside NemoClaw.
+An operator-owned adapter controls the target and retains all cloud, host administration, SSH, VNC, and service credentials.
+NemoClaw does not pass those credentials to the sandbox or store them in its registry.
+
+The adapter must be an absolute executable path.
+NemoClaw starts it without a shell, writes one `target-adapter-request` JSON object to standard input, and accepts one record from `schemas/cua-lifecycle.schema.json` on standard output.
+The adapter must return a `target-attachment` record after success or a `failure` record after failure.
+NemoClaw does not copy adapter standard error into public output.
+
+Attachment also requires a secret-free JSON manifest that matches `schemas/cua-target-manifest.schema.json`.
+The manifest contains immutable target, image, service-bundle, and protocol identities.
+It must not contain endpoints, credentials, host names, instance IDs, transport handles, or administration data.
+The manifest path must directly name a regular file no larger than 64 KiB; NemoClaw does not follow symbolic links.

+ ]
+}
+```
+
+All commands support `--json`.
+Successful commands exit `0`.
+Validation failures exit `2`, target or task conflicts exit `3`, unavailable lifecycle components exit `4`, and target health or compatibility failures exit `5`.
+Failure output uses the versioned `failure` record and does not include raw adapter diagnostics.
+
+### `$$nemoclaw cua target attach`
+
+Attach one target after its manifest, image, service bundle, and three capability checks match.
+A worker that already has a target returns `target_conflict` without invoking the adapter.
+
+```bash
+$$nemoclaw my-cua cua target attach \
+ --adapter /absolute/path/to/target-adapter \
+ --target-manifest ./target-manifest.json \
+ --json
+```
+
+### `$$nemoclaw cua target status`
+
+Read the recorded secret-free attachment projection without invoking the adapter.
+The output includes bounded target identity, capability protocol and health, and active-task state.
+It contains no endpoint or credential material.
+
+```bash
+$$nemoclaw my-cua cua target status --json
+```
+
+The same bounded projection appears as `cuaTarget` in `$$nemoclaw status --json`.
+`$$nemoclaw doctor` reports the recorded attachment state and capability health; it does not perform a live target probe.
+Run `$$nemoclaw cua target health --adapter ` for fresh validation.
+
+### `$$nemoclaw cua target health`
+
+Recover fresh authority through the host adapter.
+The command compares the observed target with the recorded identity and checks all three services.
+It records `unreachable`, `incompatible`, or `replaced` without accepting the target when validation fails.
+
+```bash
+$$nemoclaw my-cua cua target health \
+ --adapter /absolute/path/to/target-adapter \
+ --json
+```
+
+### `$$nemoclaw cua target reset`
+
+Ask the adapter to reconstruct the disposable target, browser profile, and fixture state.
+NemoClaw accepts the reset target only after its declared components and all three services pass.
+A reset can produce a new target identity.
+The command rejects reset while a task is active.
+
+```bash
+$$nemoclaw my-cua cua target reset \
+ --adapter /absolute/path/to/target-adapter \
+ --json
+```
+
+### `$$nemoclaw cua target detach`
+
+Ask the adapter to revoke target reachability.
+NemoClaw clears the attachment projection only after the adapter returns a detached record.
+The command rejects detach while a task is active.
+
+```bash
+$$nemoclaw my-cua cua target detach \
+ --adapter /absolute/path/to/target-adapter \
+ --json
+```
+
+### `$$nemoclaw cua target destroy`
+
+Ask the adapter to destroy the disposable target.
+NemoClaw clears the attachment projection only after the adapter confirms that the target is detached.
+The command rejects destroy while a task is active.
+
+```bash
+$$nemoclaw my-cua cua target destroy \
+ --adapter /absolute/path/to/target-adapter \
+ --json
+```
+
+Normal backups retain only the secret-free attachment projection.
+They exclude the target, browser profile, mutable desktop state, adapter state, and administration material.
+Recovery never reuses an attachment handle.
+The host adapter obtains fresh authority and NemoClaw validates the immutable identities again.
+
+## CUA security lifecycle
+
+These commands verify the CUA sandbox and target security boundary through one trusted, host-side verifier.
+The verifier inspects the actually applied policy, target reachability, process isolation, secret delivery, artifact handling, and fixture authority.
+It returns only a content-free `security-attestation` record.
+Private service endpoints, host names, transport details, paths, and credentials remain inside the verifier boundary.
+
+The verifier must be an absolute executable path.
+NemoClaw starts it without a shell, with a fixed credential-free environment, and writes one `security-adapter-request` JSON object to standard input.
+The request contains the sandbox name plus the public runtime-readiness and target-attachment records.
+It contains no private verifier authority, service endpoint, host name, transport detail, path, or credential.
+NemoClaw accepts one `security-attestation` or `failure` record from `schemas/cua-lifecycle.schema.json` on standard output and never copies verifier standard error into public output.
+
+A valid attestation proves that:
+
+- network access defaults to deny and permits only managed inference plus the declared browser, computer, and terminal services;
+- unrelated Internet access, cloud metadata, undeclared loopback, host administration, host desktop access, and the host Docker socket are denied;
+- provider, target, and service credentials remain in the host-side secret boundary and are absent from prompts, the sandbox filesystem, arguments, logs, state, diagnostics, backups, public JSON, and build logs;
+- the sandbox runs unprivileged as a non-root user without broad writable host mounts;
+- screenshots, page and screen content, downloads, browser profiles, cookies, mutable target state, task content, results, logs, and documents are SHA-256-addressed, owner-only, metadata-bounded, excluded from backups, and retained only until target reset or destroy; and
+- synthetic local fixtures cannot produce external side effects, and untrusted task or runtime content cannot expand authority.
+
+The attestation is valid only for the exact recorded runtime, sandbox image, target image, service bundle, policy, task protocol, inference route, capability protocols, and target identity.
+Identity drift makes the recorded attestation stale and blocks status validation and task execution.
+NemoClaw clears it after a successful target reset, detach, or destroy, or when target health records the target as unreachable, incompatible, or replaced.
+An explicit verification failure also clears any prior attestation.
+Every task operation requires a current matching attestation before it invokes the task adapter.
+
+Successful commands exit `0`.
+Validation failures exit `2`, unavailable runtime or lifecycle state exits `4`, and absent, malformed, incomplete, or identity-stale security state exits `5`.
+
+### `$$nemoclaw cua security verify`
+
+Run the trusted verifier and record its content-free attestation only when every required boundary is enforced.
+
+```bash
+$$nemoclaw my-cua cua security verify \
+ --adapter /absolute/path/to/security-verifier \
+ --json
+```
+
+### `$$nemoclaw cua security status`
+
+Validate the recorded attestation against the current runtime and target identities without invoking the verifier.
+The same content-free projection appears as `cuaSecurity` in `$$nemoclaw status --json`.
+`$$nemoclaw doctor` reports whether the attestation is present and current.
+
+```bash
+$$nemoclaw my-cua cua security status --json
+```
+
+## CUA task lifecycle
+
+These commands drive the checked-in CUA task contract through one explicit, operator-owned task adapter.
+The adapter is a protocol boundary for the selected CUA runtime; it is not a runtime plugin or a terminal-output parser.
+Interactive and headless starts use the same adapter, runtime identity, task protocol, and explicit task ID.
+Before any task adapter runs, the sandbox must have a current CUA security attestation for the exact runtime, policy, inference, target, and capability identities.
+
+The adapter must be an absolute executable path.
+NemoClaw starts it without a shell and writes one `task-adapter-request` JSON object to standard input.
+The request includes the recorded runtime and target identities plus the requested operation.
+Task, guidance, and input-required response text comes from a non-empty UTF-8 `--input-file` of at most 64 KiB.
+The path must directly name a regular file; NemoClaw does not follow symbolic links.
+That private input is sent to the adapter only; NemoClaw does not write it to lifecycle output, canonical registry state, or backups.
+
+The adapter returns one record from `schemas/cua-lifecycle.schema.json`:
+
+- A `target-attachment` record reports active `running`, `paused`, `input-required`, or `cancelling` state.
+- A terminal `task-result` record reports `succeeded`, `failed`, or `cancelled`.
+- A `task-evidence-index` record contains content-addressed private references for events, logs, or plans.
+- A `failure` record contains one bounded failure family and no raw runtime diagnostics.
+
+NemoClaw compares every terminal result with the recorded runtime, sandbox image, target image, service bundle, policy, task protocol, inference route, capability protocols, and target identity.
+Any identity drift fails closed.
+The most recent 16 terminal results remain available through `cua task result` and `cua task status` after a normal CLI reconnect.
+Private task input, screenshots, documents, page content, logs, plans, runtime files, and adapter authority are not retained.
+
+Successful commands exit `0`.
+Validation failures exit `2`, an active-task conflict exits `3`, unavailable lifecycle or runtime operations exit `4`, and execution, compatibility, target, inference, policy, timeout, or cancellation failures exit `5`.
+
+### `$$nemoclaw cua task start`
+
+Start one task with an explicit ID, execution surface, and private input file.
+A target with an active task returns `task_conflict` without invoking the adapter.
+A task ID that remains in the retained result history must not be reused.
+
+```bash
+$$nemoclaw my-cua cua task start \
+ --adapter /absolute/path/to/task-adapter \
+ --task-id task-001 \
+ --mode headless \
+ --input-file ./task.txt \

+ "classification": "private",
+ "mediaType": "application/json",
+ "sizeBytes": 42
+ }
+ ]
+}
+```
+
+### `$$nemoclaw cua task logs`
+
+Retrieve a content-addressed index for private task logs.
+
+```bash
+$$nemoclaw my-cua cua task logs \
+ --adapter /absolute/path/to/task-adapter \
+ --task-id task-001 \
+ --json
+```
+
+### `$$nemoclaw cua task plans`
+
+Retrieve a content-addressed index for private task plans.
+
+```bash
+$$nemoclaw my-cua cua task plans \
+ --adapter /absolute/path/to/task-adapter \
+ --task-id task-001 \
+ --json
+```
+
+### `$$nemoclaw cua task pause`
+
+Pause an active task when the runtime advertises `task.pause`.
+The runtime must return an updated attachment whose task state is `paused`; any other state fails validation without changing the recorded task.
+
+```bash
+$$nemoclaw my-cua cua task pause \
+ --adapter /absolute/path/to/task-adapter \
+ --task-id task-001 \
+ --json
+```
+
+### `$$nemoclaw cua task cancel`
+
+Cancel an active task.
+The runtime must return a terminal cancelled result and clear active-task state.
+A timeout or classified cancellation also clears active-task state so reconnect cannot report a task that is no longer running.
+
+```bash
+$$nemoclaw my-cua cua task cancel \
+ --adapter /absolute/path/to/task-adapter \
+ --task-id task-001 \
+ --json
+```
+
+### `$$nemoclaw cua task guide`
+
+Inject private guidance when the runtime advertises `task.guide`.
+The command uses the same private `--input-file` boundary as `cua task respond`.
+
+```bash
+$$nemoclaw my-cua cua task guide \
+ --adapter /absolute/path/to/task-adapter \
+ --task-id task-001 \
+ --input-file ./guidance.txt \
+ --json
+```
+
+### `$$nemoclaw cua task respond`
+
+Supply private input after the runtime reports `input-required` when it advertises `task.respond`.
+An unadvertised optional operation returns `lifecycle_unavailable` and does not invoke the adapter.
+
+```bash
+$$nemoclaw my-cua cua task respond \
+ --adapter /absolute/path/to/task-adapter \
+ --task-id task-001 \
+ --input-file ./response.txt \
+ --json
+```
+
### `$$nemoclaw exec`
Run a command non-interactively inside a running sandbox through the OpenShell exec endpoint.

+# First-class CUA v1 contract
+
+This contract defines the NemoClaw v1 boundary for one standalone computer-use
+agent (CUA) and one separately managed desktop target. It is the implementation
+contract for issue #7750. The public lifecycle records use
+`schemas/cua-lifecycle.schema.json`.
+
+The contract does not select an upstream runtime, target environment, cloud
+provider, or qualification adapter. Runtime and target implementations must
+record their exact artifacts and owners before they become supported.
+
+## Supported topology
+
+The CUA runs in one OpenShell-managed agent sandbox. It owns planning,
+execution, task state, recovery, and evidence production. It controls one
+dedicated, disposable, non-production desktop target.
+
+The desktop target exposes three required capabilities:
+
+- `browser`
+- `computer`
+- `terminal`
+
+Each capability has its own protocol version and health result. Attachment
+fails unless all three capabilities are healthy.
+
+Another resident agent does not invoke the CUA in v1. Direct service mode,
+cross-agent delegation, A2A, and MCP delegation are outside this contract.
+NemoClaw does not provide a dashboard or messaging surface for the CUA.
+
+## Runtime manifest
+
+The ordinary agent discovery path reads `agents/*/manifest.yaml`. The current
+terminal runtime shape represents the CUA discovery and launch requirements
+without a new runtime kind:
+
+- `runtime.kind` is `terminal`.
+- `runtime.interactive_command` starts the interactive CUA surface.
+- `runtime.headless_command` starts the headless CUA surface.
+- `version_command` returns the exact runtime version.
+- `runtime.smoke_commands` verify the runtime, managed inference, and command
+ contract without attaching a target.
+
+The CUA target and task lifecycle is not a terminal command convention. It uses
+the versioned public lifecycle records in this contract. A runtime
+implementation must use the same integrity-pinned runtime identity for
+interactive and headless operation.
+
+The production manifest must identify an integrity-pinned runtime artifact,
+sandbox image, dependency graph, policy, and task protocol. The runtime issue
+records their exact values, owner, release lifecycle, and compatibility policy
+before the manifest is accepted.
+
+## Ownership
+
+| Owner | Required ownership |
+| --- | --- |
+| NemoClaw | Agent discovery, onboarding, managed inference, sandbox lifecycle, policy, compatibility validation, secret-free attachment state, bounded public task state, recovery, rebuild, backup, update, and destroy. |
+| CUA runtime | Planning, visual grounding, computer/browser/terminal clients, active task state, results, events, plans, logs, cancellation, supported guidance, and evidence production. |
+| Host target lifecycle | Target selection or provisioning, platform and target-administration credentials, private transport, immutable target and service attestation, reset, and destroy. |
+| Qualification fixture | Synthetic accounts and data, deterministic target preparation, independent final-state verification, and private qualification evidence. |
+
+The qualification adapter is scaffolding. It may map logical qualification
+actions to public NemoClaw lifecycle operations. It must report the CUA worker
+unavailable until those operations exist. It must not replace missing product
+behavior with private shell or direct OpenShell operations.
+
+## Public lifecycle
+
+NemoClaw must expose these target operations:
+
+- `target.attach`
+- `target.status`
+- `target.health`
+- `target.detach`
+- `target.reset`
+- `target.destroy`
+
+NemoClaw must expose these required task operations:
+
+- `task.start`
+- `task.status`
+- `task.result`
+- `task.events`
+- `task.logs`
+- `task.plans`
+- `task.cancel`
+
+A runtime may advertise these optional task operations:
+
+- `task.pause`
+- `task.guide`
+- `task.respond`
+
+NemoClaw also exposes these security operations:
+
+- `security.verify`
+- `security.status`
+
+The runtime-readiness record always lists every required task operation and
+lists an optional operation only when the runtime implements it. A request for
+an unlisted optional operation returns `lifecycle_unavailable`; it is never
+silently accepted.
+
+Public command names, arguments, output envelopes, and exit codes are owned by
+the target, task, and security implementation issues. They must produce records
+that conform to this contract without reading runtime-private files.
+
+Active task commands return the target attachment with its bounded
+`activeTask` projection. Terminal commands return `task-result`.
+`task.events`, `task.logs`, and `task.plans` return a
+`task-evidence-index` containing only content-addressed private references.
+
+## Compatibility identities
+
+Every component identity contains:
+
+- a component name;
+- an immutable version;
+- a SHA-256 digest;
+- an accountable owner.
+
+Runtime readiness identifies the runtime, sandbox image, policy, task protocol,
+inference provider, and model. An attachment also identifies the target image,
+target platform, target service bundle, and three capability protocol versions.
+A task result binds all of those identities, the three capability protocol
+versions, and the content identity of the attached target.
+
+Mutable tags, `latest`, local paths, host names, provider selectors, and
+environment-specific instance identifiers are not compatibility identities.
+
+### Compatibility policy
+
+NemoClaw accepts a component only when its observed name, version, owner, and
+SHA-256 digest match the recorded identity. A tag or version match does not
+override a digest mismatch.
+
+CUA lifecycle consumers accept schema major 1 and reject unknown major
+versions before reading the record. A minor or patch schema change may add no
+authority and must preserve every required v1 field and invariant.
+
+Target attachment requires the recorded target platform, image, service
+bundle, and capability protocol versions. Recovery treats a changed target
+identity as replacement, not as the prior attachment. It obtains fresh
+authority only after compatibility validation succeeds.
+
+Any runtime, sandbox image, target image, service bundle, policy, task
+protocol, inference model, or dependency change requires the CUA compatibility
+test before release qualification. Each upstream owner must publish immutable
+release identities, supported successor rules, and an end-of-support decision
+before NemoClaw records that implementation as supported.
+
+## Cardinality and authority
+
+One CUA worker has at most one attached target. One target has at most one
+active task. A conflicting target returns `target_conflict`. A conflicting task
+returns `task_conflict` without disturbing the current attachment or task.
+
+Worker leases, attachment handles, task handles, service sessions, and
+transport identifiers are opaque, non-durable authority. They are never
+written to the public records, registry, backup, task input, or result.
+Recovery obtains fresh authority after it validates immutable component
+identities.
+
+## State
+
+| Class | State |
+| --- | --- |
+| NemoClaw persistent | Selected agent, compatibility identities, managed inference selection, policy identity, secret-free target attachment projection, content-free security attestation, and bounded completed-task metadata and evidence references. |
+| User managed | Explicit onboarding choices and supported agent preferences. Secret values remain in their supported credential boundary. |
+| Reconstructible | CUA sandbox, desktop target, browser profile, mutable fixture data, service sessions, and runtime caches. |
+| Private | Screenshots, page and screen content, documents, downloads, detailed logs, task input, runtime observations, and detailed verification output. |
+| Non-durable authority | Worker leases, attachment and task handles, service sessions, transport identifiers, host paths, and target-administration material. |
+
+Backups contain only declared NemoClaw persistent and user-managed state.
+Backups exclude reconstructible state, private artifacts, and non-durable
+authority.
+
+Rebuild and recovery validate all immutable identities before they replace or
+reuse state. They obtain a fresh target attachment and service sessions.
+Update fails before deleting the current sandbox when the replacement runtime
+or managed inference route cannot be verified.
+
+Detach invalidates target reachability and clears the attachment projection.
+Reset reconstructs the target, browser profile, and fixture state. Destroy
+removes target reachability, private artifacts subject to the retention policy,
+and all NemoClaw-owned CUA state.
+
+## Secret and artifact boundary
+
+Public CUA records contain no credential values, credential-shaped fields,
+service endpoints, host or instance identities, SSH or VNC details, arbitrary
+commands, environment values, host paths, leases, sessions, or transport
+identifiers. Producers construct component and inference identities from
+trusted manifest or registry fields, never from runtime-authored output, and
+apply NemoClaw's standard redaction before serialization.
+
+The attachment record uses only a content identity for the target. Detailed
+screenshots, logs, page content, documents, and task artifacts remain private.
+Public results refer to private evidence by SHA-256 digest, media type, and
+optional byte count. An evidence reference contains no path or URL.
+
+An agent-authored result is not independent verification. A public task result
+contains the agent's terminal status and a digest for its private result,
+independent verification status and evidence digests, per-capability receipts,
+and private evidence references as separate fields.
+
+`task-result` records are terminal: `succeeded`, `failed`, or `cancelled`.
+`input-required` is an active task status and cannot appear in a result. A
+succeeded task requires both a succeeded agent result and passed independent
+verification. A failed task cannot contain both of those success conditions.
+The task and agent result must agree on cancellation.
+
+NemoClaw retains at most the 16 most recent validated terminal results for
+normal CLI reconnect inspection. It never persists task input. A task ID in
+that retained set cannot be reused.
+
+Before a task adapter runs, NemoClaw requires a current `security-attestation`
+record. A trusted host-side verifier produces that content-free record only
+after it validates the policy applied to the sandbox and target. The
+attestation is bound to the exact runtime, sandbox image, target image, service
+bundle, policy, task protocol, inference route, capability protocols, and
+target identity.
+
+The verifier must prove all of these conditions:
+
+- network access defaults to deny and permits only managed inference plus the
+ declared browser, computer, and terminal target services;
+- unrelated Internet access, cloud metadata, undeclared loopback, host
+ administration, host desktop access, and the host Docker socket are denied;
+- provider, target, and service credentials remain in the host-side secret
+ boundary and are absent from prompts, the sandbox filesystem, process
+ arguments, logs, state, diagnostics, backups, public JSON, and build logs;
+- the sandbox runs unprivileged as a non-root user without broad writable host
+ mounts;
+- screenshots, page and screen content, downloads, browser profiles, cookies,
+ mutable target state, task content, results, logs, and documents are
+ content-addressed, owner-only, metadata-bounded, excluded from backups, and
+ removed by target reset or destroy according to the retention boundary; and
+- qualification uses synthetic local fixtures, denies external side effects,
+ and never lets task input, page or screen content, downloads, or runtime
+ output expand authority.
+
+The verifier owns any private endpoint and credential inspection needed to
+make those assertions. Its request contains the sandbox name and public
+runtime-readiness and target-attachment records, but no private verifier
+authority; its attestation contains none of those private values. NemoClaw
+rejects malformed, incomplete, or identity-stale attestations. Identity drift
+makes an attestation stale and blocks task execution. Target reset, detach,
+or destroy clears it after the target operation succeeds. Target health also
+clears it when it records the target as unreachable, incompatible, or replaced,
+and an explicit verification failure clears any prior attestation, so task
+execution remains fail-closed until verification succeeds again.
+
+## Failure families
+
+Public failures use one deterministic family:
+
+| Family | Condition |
+| --- | --- |
+| `lifecycle_unavailable` | A required public operation or optional runtime operation is unavailable. |
+| `runtime_unavailable` | The CUA runtime cannot start or answer its version or smoke command. |
+| `runtime_incompatible` | The runtime, sandbox image, dependency, or task protocol identity does not match. |
+| `inference_unavailable` | The managed inference route cannot serve the runtime. |
+| `policy_invalid` | The required policy is absent, malformed, changed, or cannot be applied. |
+| `target_unreachable` | The recorded target cannot be reached through the supported attachment boundary. |
+| `target_replaced` | The target identity changed after attachment. |
+| `target_incompatible` | The target image or service bundle identity does not match. |
+| `capability_unhealthy` | Browser, computer, or terminal health validation fails. |
+| `target_conflict` | The worker already has a target. |
+| `task_conflict` | The target already has an active task. |
+| `task_timeout` | The task reaches its bounded execution limit. |
+| `task_cancelled` | Cancellation reaches a terminal state. |
+| `validation_failed` | Public input, output, evidence, or independent verification is malformed or fails. |
+
+Failures identify the operation, family, retryability, and bounded component.
+They do not include raw runtime output or private target details.
+
+Attachment and task execution fail before mutation when required lifecycle
+operations, identities, capability health, managed inference, or policy cannot
+be validated.
+
+## Qualification
+
+Release qualification uses independent browser, computer, and terminal tests
+plus one integrated task. Code outside the agent verifies final state. The
+qualification receipt binds the exact runtime, sandbox, target, service,
+inference, policy, task protocol, fixture, and verifier identities.
+
+Qualification may run through a host-owned adapter, but the adapter must call
+the supported public NemoClaw lifecycle. Private qualification evidence does
+not enter the public issue, contract, or repository.

+## CUA GPU qualification
+
+NemoClaw owns the fail-closed consumer gate for GPU-backed CUA qualification.
+The image and Launchable producer owns environment provisioning and writes
+`/etc/nemoclaw/cua-qualification-environment.json`. That bounded public
+identity contains only the Launchable version and digest, exact NemoClaw
+candidate commit, GPU count and model, driver, CUDA, container-toolkit, and
+digest-pinned probe-image identities. It must not contain Brev authority,
+workspace or host identity, service endpoints, or credentials.
+
+An operator-owned scenario runner uses NemoClaw's public CUA lifecycle and
+independent fixture oracles, then writes
+`/var/lib/nemoclaw/cua-qualification-receipt.json`. The receipt parser in
+`tools/e2e/cua-qualification-receipt.mts` requires all four browser, terminal,
+computer, and integrated scenario claims; exact component and inference
+identities; a repeated run after recreation; the security-negative suite; and
+cleanup. The runner's independent oracles provide the evidence behind those
+claims. Screenshots, documents, task content, and detailed oracle output
+remain private. A producer that cannot provide every required identity and
+result must fail closed instead of writing a partial file.
+
+After the operator-owned qualification runner writes the receipt, run the
+public gate on the GPU instance:
+
+```bash
+NEMOCLAW_RUN_LIVE_E2E=1 \
+NEMOCLAW_RUN_CUA_GPU_QUALIFICATION=1 \
+npx vitest run --project e2e-live test/e2e/live/cua-gpu-qualification.test.ts
+```
+
+The gate validates both public files and compares the receipt with the
+environment identity, checked-out candidate commit, and live GPU count. It
+does not build the image, provision the Launchable, run the scenario, or
+independently prove the detailed evidence behind the receipt. Those
+responsibilities remain with the environment and scenario producers. An
+adapter's or agent's own success claim is not qualification evidence.
+
+This gate does not demonstrate a passing CUA qualification and must not close
+Issue #7753 until a public pinned runtime and complete live evidence are
+available.
