+# OpenShell 0.0.67 Gateway Auth Review
+
+Review date: 2026-06-22
+
+Scope: NemoClaw Docker-driver gateway config generated for OpenShell `0.0.67`.
+
+## Source Review
+
+Reviewed upstream source at `NVIDIA/OpenShell@v0.0.67` (`ce788b50f9b1f977a4327e4484c5b663013dd9a5`):
+
+- `crates/openshell-core/src/config.rs`: `GatewayAuthConfig.allow_unauthenticated_users` is documented as an unsafe local-development escape hatch for user/CLI calls; sandbox supervisor calls still use gateway-minted sandbox JWTs.
+- `crates/openshell-server/src/lib.rs`: when `gateway_jwt` is configured, OpenShell reads the configured signing key, public key, and kid, then installs both `SandboxJwtIssuer` and `SandboxJwtAuthenticator`.
+- `crates/openshell-server/src/auth/sandbox_jwt.rs`: sandbox JWTs are Ed25519/EdDSA, require the configured `kid`, `iss`, `aud`, and `sub`, and reject expired tokens while allowing non-matching `kid` values to fall through to other authenticators.
+- `crates/openshell-server/src/multiplex.rs`: a local unauthenticated user principal is allowed only when `allow_unauthenticated_users` is true; user principals are rejected from sandbox-only methods with `permission_denied`, while sandbox principals are checked against the sandbox method allowlist.
+
+## NemoClaw Boundary
+
+NemoClaw keeps `allow_unauthenticated_users = true` so local OpenShell CLI/API provider-registration calls remain compatible with OpenShell 0.0.67. The generated `gateway_jwt` bundle remains the sandbox supervisor auth path, and stale `OPENSHELL_DISABLE_GATEWAY_AUTH` env is scrubbed before launch.
+
+The Docker-hosted compatibility gateway now defaults to `127.0.0.1`. Binding the compatibility gateway to `0.0.0.0` is an explicit operator override via `NEMOCLAW_OPENSHELL_GATEWAY_COMPAT_BIND_ADDRESS=0.0.0.0`, because OpenShell 0.0.67 does not distinguish a local unauthenticated user caller from a remote unauthenticated caller once the socket is reachable.
+
+## Local Coverage
+
+- `src/lib/onboard/docker-driver-gateway-config.test.ts` verifies the generated TOML/JWT bundle, key reuse/regeneration, wrong kid, wrong gateway id, expired token rejection, and the OpenShell 0.0.67 auth-router contract for local user versus sandbox principals.
+- `src/lib/onboard/docker-driver-gateway-launch.test.ts` verifies loopback default binding, explicit wildcard override, stale auth-disable env scrubbing, generated `OPENSHELL_GATEWAY_CONFIG`, and the wildcard warning log.

 NemoClaw keeps `allow_unauthenticated_users = true` so local OpenShell CLI/API provider-registration calls remain compatible with OpenShell 0.0.67. The generated `gateway_jwt` bundle remains the sandbox supervisor auth path, and stale `OPENSHELL_DISABLE_GATEWAY_AUTH` env is scrubbed before launch.
 
-The Docker-hosted compatibility gateway now defaults to `127.0.0.1`. Binding the compatibility gateway to `0.0.0.0` is an explicit operator override via `NEMOCLAW_OPENSHELL_GATEWAY_COMPAT_BIND_ADDRESS=0.0.0.0`, because OpenShell 0.0.67 does not distinguish a local unauthenticated user caller from a remote unauthenticated caller once the socket is reachable.

 - `crates/openshell-core/src/config.rs`: `GatewayAuthConfig.allow_unauthenticated_users` is documented as an unsafe local-development escape hatch for user/CLI calls; sandbox supervisor calls still use gateway-minted sandbox JWTs.
 - `crates/openshell-server/src/lib.rs`: when `gateway_jwt` is configured, OpenShell reads the configured signing key, public key, and kid, then installs both `SandboxJwtIssuer` and `SandboxJwtAuthenticator`.
+- `crates/openshell-server/src/lib.rs`: the server binds the configured main listener plus compute-driver `gateway_bind_addresses`, skipping only driver addresses already covered by a wildcard listener.
 - `crates/openshell-server/src/auth/sandbox_jwt.rs`: sandbox JWTs are Ed25519/EdDSA, require the configured `kid`, `iss`, `aud`, and `sub`, and reject expired tokens while allowing non-matching `kid` values to fall through to other authenticators.
+- `crates/openshell-driver-docker/src/lib.rs`: Docker-driver sandboxes see loopback and arbitrary hostnames rewritten to `host.openshell.internal:<gateway-port>`, and native Linux Docker gets a bridge-gateway bind address such as `<docker-bridge-gateway-ip>:<gateway-port>`.
 - `crates/openshell-server/src/multiplex.rs`: a local unauthenticated user principal is allowed only when `allow_unauthenticated_users` is true; user principals are rejected from sandbox-only methods with `permission_denied`, while sandbox principals are checked against the sandbox method allowlist.
 
 ## NemoClaw Boundary
 
 NemoClaw keeps `allow_unauthenticated_users = true` so local OpenShell CLI/API provider-registration calls remain compatible with OpenShell 0.0.67. The generated `gateway_jwt` bundle remains the sandbox supervisor auth path, and stale `OPENSHELL_DISABLE_GATEWAY_AUTH` env is scrubbed before launch.
 
-The Docker-hosted compatibility gateway is forced to `127.0.0.1`. `NEMOCLAW_OPENSHELL_GATEWAY_COMPAT_BIND_ADDRESS=0.0.0.0` is rejected, because OpenShell 0.0.67 does not distinguish a local unauthenticated user caller from a remote unauthenticated caller once the socket is reachable.
+The Docker-hosted compatibility gateway keeps the main OpenShell listener on `127.0.0.1`. Sandbox callback reachability is preserved by OpenShell's Docker driver: it rewrites the sandbox-facing endpoint to `host.openshell.internal:<gateway-port>` and the OpenShell server adds the computed Docker bridge listener when that route is needed. `NEMOCLAW_OPENSHELL_GATEWAY_COMPAT_BIND_ADDRESS=0.0.0.0` is rejected, because OpenShell 0.0.67 does not distinguish a local unauthenticated user caller from a remote unauthenticated caller once the main socket is reachable.
+
+Package-managed Docker-driver gateways also reject `NEMOCLAW_GATEWAY_BIND_ADDRESS=0.0.0.0` while NemoClaw uses `allow_unauthenticated_users = true`. Use the dashboard bind setting for remote dashboard exposure instead of widening the OpenShell gateway's unauthenticated local-user compatibility surface.
+
+## Upstream Contract Coverage
+
+Local run against `NVIDIA/OpenShell@v0.0.67`:
+
+- `cargo test -p openshell-server sandbox_jwt -- --nocapture`: passed 7 sandbox JWT tests, including `mint_and_validate_round_trip`, `token_signed_by_other_key_is_rejected`, `malformed_token_is_rejected`, and `expired_token_is_rejected`.
+- `cargo test -p openshell-server unauthenticated_dev_user -- --nocapture`: passed `unauthenticated_dev_user_fills_missing_principal_when_enabled` and `unauthenticated_dev_user_authenticates_without_chain_when_enabled`.
+- `cargo test -p openshell-server sandbox_principal_can_call_allowlisted_method -- --nocapture`: passed.
+- `cargo test -p openshell-server user_principal_is_denied_on_sandbox_only_methods -- --nocapture`: passed.
+- `cargo test -p openshell-server gateway_listener_addresses -- --nocapture`: passed `gateway_listener_addresses_include_driver_address_on_distinct_ip` and `gateway_listener_addresses_skip_driver_address_covered_by_wildcard`.
+- `cargo test -p openshell-driver-docker container_visible_endpoint_rewrites_loopback_hosts -- --nocapture`: passed.
+- `cargo test -p openshell-driver-docker docker_gateway_route_uses_bridge_gateway_for_linux_docker -- --nocapture`: passed.
 
 ## Local Coverage
 
 - `src/lib/onboard/docker-driver-gateway-config.test.ts` verifies the generated TOML/JWT bundle, key reuse/regeneration, wrong kid, wrong gateway id, expired token rejection, and the OpenShell 0.0.67 auth-router contract for local user versus sandbox principals.
-- `src/lib/onboard/docker-driver-gateway-launch.test.ts` verifies loopback binding, wildcard override rejection, stale auth-disable env scrubbing, and generated `OPENSHELL_GATEWAY_CONFIG`.
+- `src/lib/onboard/docker-driver-gateway-env.test.ts` verifies package-managed Docker-driver gateway startup rejects wildcard binds while the OpenShell 0.0.67 local-user compatibility auth path is active.
+- `src/lib/onboard/docker-driver-gateway-launch.test.ts` verifies loopback main binding, wildcard override rejection, stale auth-disable env scrubbing, and generated `OPENSHELL_GATEWAY_CONFIG`.

 ## Upstream Contract Coverage
 
+Executable NemoClaw live scenario:

+- `test/e2e-scenario/live/openshell-gateway-source-contract.test.ts` checks out `NVIDIA/OpenShell@v0.0.67` at `ce788b50f9b1f977a4327e4484c5b663013dd9a5`, generates NemoClaw's `OPENSHELL_GATEWAY_CONFIG`, injects a temporary OpenShell integration test that loads that exact TOML through `openshell_server::config_file::load()`, and runs the upstream OpenShell auth/listener contract tests below.
+- Manual scenario selector: `scenarios=openshell-gateway-source-contract`; the default all-scenarios dispatch includes the same free-standing job.
+
 Local run against `NVIDIA/OpenShell@v0.0.67`:
 
 - `cargo test -p openshell-server sandbox_jwt -- --nocapture`: passed 7 sandbox JWT tests, including `mint_and_validate_round_trip`, `token_signed_by_other_key_is_rejected`, `malformed_token_is_rejected`, and `expired_token_is_rejected`.

 ## NemoClaw Boundary
 
-NemoClaw keeps `allow_unauthenticated_users = true` so local OpenShell CLI/API provider-registration calls remain compatible with OpenShell 0.0.67. The generated `gateway_jwt` bundle remains the sandbox supervisor auth path, and stale `OPENSHELL_DISABLE_GATEWAY_AUTH` env is scrubbed before launch.
+NemoClaw generates `allow_unauthenticated_users = false` whenever it writes the Docker-driver `gateway_jwt` config. OpenShell 0.0.67 can add Docker bridge reachability for sandbox callbacks, and its unauthenticated local-user escape hatch is not origin-scoped, so no-token Docker bridge user calls fail closed instead of becoming `local-dev-user`. The generated `gateway_jwt` bundle remains the sandbox supervisor auth path, and stale `OPENSHELL_DISABLE_GATEWAY_AUTH` env is scrubbed before launch.
 
-The Docker-hosted compatibility gateway keeps the main OpenShell listener on `127.0.0.1`. Sandbox callback reachability is preserved by OpenShell's Docker driver: it rewrites the sandbox-facing endpoint to `host.openshell.internal:<gateway-port>` and the OpenShell server adds the computed Docker bridge listener when that route is needed. `NEMOCLAW_OPENSHELL_GATEWAY_COMPAT_BIND_ADDRESS=0.0.0.0` is rejected, because OpenShell 0.0.67 does not distinguish a local unauthenticated user caller from a remote unauthenticated caller once the main socket is reachable.

-Package-managed Docker-driver gateways also reject `NEMOCLAW_GATEWAY_BIND_ADDRESS=0.0.0.0` while NemoClaw uses `allow_unauthenticated_users = true`. Use the dashboard bind setting for remote dashboard exposure instead of widening the OpenShell gateway's unauthenticated local-user compatibility surface.

 ## NemoClaw Boundary
 
-NemoClaw generates `allow_unauthenticated_users = false` whenever it writes the Docker-driver `gateway_jwt` config. OpenShell 0.0.67 can add Docker bridge reachability for sandbox callbacks, and its unauthenticated local-user escape hatch is not origin-scoped, so no-token Docker bridge user calls fail closed instead of becoming `local-dev-user`. The generated `gateway_jwt` bundle remains the sandbox supervisor auth path, and stale `OPENSHELL_DISABLE_GATEWAY_AUTH` env is scrubbed before launch.
+NemoClaw generates `gateway_jwt` config for sandbox supervisor callbacks while preserving `allow_unauthenticated_users = true` so host-side OpenShell CLI user calls remain available. OpenShell 0.0.67 still expects local user calls such as `openshell sandbox list` and `openshell sandbox delete` to work without an explicit bearer token. A full fail-closed user-auth boundary is therefore not claimed by this PR; it should move to a follow-up once OpenShell provides a trusted local-user auth path or NemoClaw can send user auth for host-side provider registration.
 
-The Docker-hosted compatibility gateway keeps the main OpenShell listener on `127.0.0.1`. Sandbox callback reachability is preserved by OpenShell's Docker driver: it rewrites the sandbox-facing endpoint to `host.openshell.internal:<gateway-port>` and the OpenShell server adds the computed Docker bridge listener when that route is needed. `NEMOCLAW_OPENSHELL_GATEWAY_COMPAT_BIND_ADDRESS=0.0.0.0` is rejected because the bridge/listener boundary relies on gateway JWT auth, not unauthenticated user fallback.

 Scope: NemoClaw Docker-driver gateway config generated for OpenShell `0.0.67`.
 
+## Source-of-Truth Boundaries
+
+- OpenShell gateway auth source contract: invalid state is an OpenShell `0.0.67` Docker-driver gateway launched from NemoClaw without the upstream config-file auth policy, local mTLS bundle, sandbox JWT bundle, or Docker bridge callback route that OpenShell expects. Source boundary is upstream OpenShell config/auth/listener/Docker-driver behavior; NemoClaw only generates config, local TLS/JWT material, bind policy, and launch env. Regression coverage is the live `openshell-gateway-auth-source-contract` scenario plus local config/env/launch tests. Remove the NemoClaw-local compatibility notes when OpenShell exposes a stable SDK/config contract that makes this generated config surface unnecessary.
+- Markerless sandbox gateway recovery output: invalid state is newer OpenShell sandbox exec/relaunch output that starts the gateway launcher but omits NemoClaw's legacy `GATEWAY_PID=` or `ALREADY_RUNNING` markers. Source boundary is OpenShell exec/recovery output format; NemoClaw treats the text as "may have started" only and still requires a healthy gateway probe. Regression coverage lives in `test/cli/connect-recovery-markerless.test.ts`. Remove the markerless heuristic when OpenShell provides a stable machine-readable recovery marker.
+- Sessions admin gateway RPC helper: invalid state is a host CLI session reset/delete action that needs OpenClaw backend/operator scope while preserving gateway token, loopback, and auto-pair boundaries. Source boundary is OpenClaw's gateway-runtime API; NemoClaw's helper is limited to `sessions.reset` and `sessions.delete`. Regression coverage lives in `src/lib/actions/sandbox/sessions/gateway-rpc-call.test.ts`. Add new methods only with a caller, allowlist entry, and negative test.
+
+## Acceptance Mapping
+
+Issue #5591 is the dependency-update umbrella. Its literal proposed-design clauses map across the split dependency PRs:
+
+- `Latest stable version of Hermes`: handled by PR #5594 (`dep/hermes-v2026.6.19`), not by this OpenShell PR.
+- `Latest version of OpenShell`: this PR pins and validates OpenShell `0.0.67`.
+- `Latest stable version of OpenClaw`: handled by PR #5595 (`dep/openclaw-2026.6.9`), not by this OpenShell PR.
+
+Issue #2478 is not an acceptance target for this OpenShell version-pin PR. Its crash-loop clauses include "Every time it boots, it crashes on the same line" and "`connect` doesn't auto-recover" because `@homebridge/ciao` calls `os.networkInterfaces()` under sandbox netlink restrictions. The source fix remains the existing guard-chain/preload work validated by `test/e2e-scenario/live/issue-2478-crash-loop-recovery.test.ts`. This PR only updates markerless recovery wrapper behavior: newer OpenShell relaunch output can be accepted after, and only after, the gateway health probe succeeds.

 The probe is bounded by an in-sandbox `openshell sandbox exec` with a hard timeout, captures only short matched bridge log signals (e.g. `connection.open`, `401 unauthorized`, `qr expired`), and never forwards message bodies to the host diagnostic output.
 
+### `$$nemoclaw <name> mcp list`
+
+List MCP bridges configured for a sandbox.
+The command reports the selected agent's MCP support status and, for each configured bridge, whether the host proxy appears to be running.
+
+```bash
+$$nemoclaw my-assistant mcp list [--json]
+```
+
+| Flag | Description |
+|------|-------------|
+| `--json` | Emit sandbox, support, and bridge state as JSON with bridge tokens redacted |
+
+### `$$nemoclaw <name> mcp add`
+
+Bridge a host-side stdio MCP server into an OpenClaw sandbox.
+Credentials stay in the host process environment: pass `--env KEY` to reference an existing host environment variable, or `--env KEY=VALUE` to use an inline value only for the initial proxy launch.
+NemoClaw persists only the environment variable names, allocates a loopback bridge port, applies a generated sandbox network policy for `host.docker.internal:<port>`, and registers the endpoint with OpenClaw through `mcporter`.
+Agents without bridge support fail before proxy, policy, or registry state is created.
+
+```bash
+$$nemoclaw my-assistant mcp add github --env GITHUB_TOKEN -- npx -y @modelcontextprotocol/server-github
+```
+
+### `$$nemoclaw <name> mcp status`
+
+Inspect MCP bridge state for one server or for all configured bridges.
+Status includes proxy liveness, generated policy presence, adapter registration, port, environment readiness, and the selected agent's MCP support mode.
+
+```bash
+$$nemoclaw my-assistant mcp status [server] [--json]
+```
+
+| Flag | Description |
+|------|-------------|
+| `--json` | Emit status as JSON with bridge tokens redacted |
+
+### `$$nemoclaw <name> mcp restart`
+
+Restart one MCP bridge proxy, or every bridge on the sandbox when no server is supplied.
+Restart requires all referenced host environment variables to be present, reapplies the generated policy if needed, and refreshes the OpenClaw `mcporter` registration.
+
+```bash
+$$nemoclaw my-assistant mcp restart [server]
+```
+
+### `$$nemoclaw <name> mcp remove`
+
+Remove an MCP bridge from a sandbox.
+NemoClaw unregisters the OpenClaw adapter, removes the generated policy, stops the host proxy, deletes runtime files, and clears the sandbox registry entry.
+
+```bash
+$$nemoclaw my-assistant mcp remove github [--force]
+```
+
+| Flag | Description |
+|------|-------------|
+| `--force` | Best-effort cleanup that also clears stale registry and runtime state |
+
 ### `$$nemoclaw <name> skill install <path>`
 
 Deploy a skill directory to a running sandbox.

 The probe is bounded by an in-sandbox `openshell sandbox exec` with a hard timeout, captures only short matched bridge log signals (e.g. `connection.open`, `401 unauthorized`, `qr expired`), and never forwards message bodies to the host diagnostic output.
 
+### `nemohermes <name> mcp list`
+
+List MCP bridges configured for a sandbox.
+The command reports the selected agent's MCP support status and, for each configured bridge, whether the host proxy appears to be running.
+
+```bash
+nemohermes my-assistant mcp list [--json]
+```
+
+| Flag | Description |
+|------|-------------|
+| `--json` | Emit sandbox, support, and bridge state as JSON with bridge tokens redacted |
+
+### `nemohermes <name> mcp add`
+
+Bridge a host-side stdio MCP server into an OpenClaw sandbox.
+Credentials stay in the host process environment: pass `--env KEY` to reference an existing host environment variable, or `--env KEY=VALUE` to use an inline value only for the initial proxy launch.
+NemoClaw persists only the environment variable names, allocates a loopback bridge port, applies a generated sandbox network policy for `host.docker.internal:<port>`, and registers the endpoint with OpenClaw through `mcporter`.
+Agents without bridge support fail before proxy, policy, or registry state is created.
+
+```bash
+nemohermes my-assistant mcp add github --env GITHUB_TOKEN -- npx -y @modelcontextprotocol/server-github
+```
+
+### `nemohermes <name> mcp status`
+
+Inspect MCP bridge state for one server or for all configured bridges.
+Status includes proxy liveness, generated policy presence, adapter registration, port, environment readiness, and the selected agent's MCP support mode.
+
+```bash
+nemohermes my-assistant mcp status [server] [--json]
+```
+
+| Flag | Description |
+|------|-------------|
+| `--json` | Emit status as JSON with bridge tokens redacted |
+
+### `nemohermes <name> mcp restart`
+
+Restart one MCP bridge proxy, or every bridge on the sandbox when no server is supplied.
+Restart requires all referenced host environment variables to be present, reapplies the generated policy if needed, and refreshes the OpenClaw `mcporter` registration.
+
+```bash
+nemohermes my-assistant mcp restart [server]
+```
+
+### `nemohermes <name> mcp remove`
+
+Remove an MCP bridge from a sandbox.
+NemoClaw unregisters the OpenClaw adapter, removes the generated policy, stops the host proxy, deletes runtime files, and clears the sandbox registry entry.
+
+```bash
+nemohermes my-assistant mcp remove github [--force]
+```
+
+| Flag | Description |

+# Set Up MCP Bridges
+
+NemoClaw MCP bridges let a sandboxed agent use a host-side MCP server without
+copying external service credentials into the sandbox.
+
+The bridge has three parts:
+
+- a host stdio-to-HTTP MCP proxy bound to `127.0.0.1`;
+- a generated OpenShell network policy for `host.docker.internal:<port>` using
+  `protocol: mcp`;
+- an agent adapter that registers the HTTP endpoint inside the sandbox.
+
+This depends on the OpenShell MCP/JSON-RPC L7 policy support from
+NVIDIA/OpenShell#1865. NemoClaw requires an OpenShell release that exposes the
+`allow_all_known_mcp_methods` policy capability before MCP bridges are enabled.
+
+## Add A Bridge
+
+OpenClaw:
+
+```bash
+export GITHUB_TOKEN=ghp_...
+nemoclaw my-openclaw mcp add github --env GITHUB_TOKEN -- npx -y @modelcontextprotocol/server-github
+```
+
+Hermes:
+
+```bash
+export GITHUB_TOKEN=ghp_...
+nemoclaw my-hermes mcp add github --env GITHUB_TOKEN -- npx -y @modelcontextprotocol/server-github
+```
+
+LangChain Deep Agents Code:
+
+```bash
+export GITHUB_TOKEN=ghp_...
+nemoclaw my-dcode mcp add github --env GITHUB_TOKEN -- npx -y @modelcontextprotocol/server-github
+```
+
+The command after `--` runs on the host as your current user. Use MCP servers
+you trust. `--env KEY` reads the value from the host process environment when
+the proxy starts, persists only the variable name, and never writes the raw
+external API key to the sandbox registry or sandbox config.
+
+For one-time bootstrap you can pass `--env KEY=VALUE`. NemoClaw uses `VALUE`
+only for that initial proxy launch and still persists only `KEY`; later
+`restart` requires `KEY` to be exported in the host environment.
+
+## Agent Adapters
+
+OpenClaw uses `mcporter config add` in the sandbox.
+
+Hermes writes an HTTP entry under `/sandbox/.hermes/config.yaml`:
+
+```yaml
+mcp_servers:
+  github:
+    url: http://host.docker.internal:3100
+    headers:
+      Authorization: Bearer <bridge-token>
+```
+
+LangChain Deep Agents Code writes an HTTP entry under `/sandbox/.mcp.json`:
+
+```json
+{
+  "mcpServers": {
+    "github": {
+      "type": "http",
+      "url": "http://host.docker.internal:3100",
+      "headers": {
+        "Authorization": "Bearer <bridge-token>"
+      }
+    }
+  }
+}
+```
+
+The bridge token is a local bearer token for the host proxy. External service
+keys such as `GITHUB_TOKEN` remain host-side in the MCP server process
+environment.
+
+## Operate Bridges
+
+```bash
+nemoclaw my-sandbox mcp list
+nemoclaw my-sandbox mcp status github --json
+nemoclaw my-sandbox mcp restart github
+nemoclaw my-sandbox mcp remove github
+```
+
+`status --json` redacts bridge tokens and never includes environment values. It
+reports proxy liveness, host environment readiness, generated policy presence,
+and adapter registration state.
+
+`remove --force` performs best-effort cleanup for stale proxies, generated
+policy records, adapter config, and registry entries.
+
+## Troubleshooting
+
+If `restart` fails with a missing host environment variable, export the same
+variable name used during `add` and retry.
+
+If the proxy times out during startup, check the bridge log shown by
+`mcp status`. Cold `npx` launches can take longer than a warm command, so
+NemoClaw waits longer than normal process probes before declaring startup
+failed.
+
+If the sandbox cannot reach `host.docker.internal`, the current v1 bridge stays

 - no-token Docker sandbox-origin access to a user-callable gateway API is rejected or unreachable;
-- valid sandbox JWT access from Docker origin to an allowlisted sandbox method reaches OpenShell auth over `host.openshell.internal` with the generated guest mTLS material, and is not rejected as unauthenticated or cross-sandbox;

 - inherited `OPENSHELL_DISABLE_GATEWAY_AUTH=true` remains scrubbed from the launch env.

-NemoClaw MCP bridges let a sandboxed agent use a host-side MCP server without
-copying external service credentials into the sandbox.
+NemoClaw MCP support lets a sandboxed agent use MCP Streamable HTTP servers
+without copying external service credentials into the sandbox.
 
-The bridge has three parts:
+The integration has three parts:
 
-- a host stdio-to-HTTP MCP proxy bound to `127.0.0.1`;
-- a generated OpenShell network policy for `host.docker.internal:<port>` using
-  `protocol: mcp`;
-- an agent adapter that registers the HTTP endpoint inside the sandbox.
+- an OpenShell provider that stores host-side credentials;
+- a generated OpenShell network policy for the MCP endpoint using `protocol: mcp`;
+- an agent adapter that writes the MCP endpoint into OpenClaw, Hermes, or
+  LangChain Deep Agents Code config.
 
 This depends on the OpenShell MCP/JSON-RPC L7 policy support from
 NVIDIA/OpenShell#1865. NemoClaw requires an OpenShell release that exposes the
-`allow_all_known_mcp_methods` policy capability before MCP bridges are enabled.
+`protocol: mcp` policy capability before managed MCP servers are enabled.

-The command after `--` runs on the host as your current user. Use MCP servers
-you trust. `--env KEY` reads the value from the host process environment when
-the proxy starts, persists only the variable name, and never writes the raw
-external API key to the sandbox registry or sandbox config.
+`--env KEY` reads the value from the host process environment and stores it in
+OpenShell's provider store. NemoClaw persists only the variable name, writes
+`openshell:resolve:env:KEY` into the sandbox-side MCP config, and relies on
+OpenShell to resolve the placeholder at egress.
 
-For one-time bootstrap you can pass `--env KEY=VALUE`. NemoClaw uses `VALUE`
-only for that initial proxy launch and still persists only `KEY`; later
-`restart` requires `KEY` to be exported in the host environment.
+For one-time bootstrap you can pass `--env KEY=VALUE`. NemoClaw forwards
+`VALUE` only to `openshell provider create/update` and still persists only
+`KEY`.

 ## Troubleshooting
 
-If `restart` fails with a missing host environment variable, export the same
-variable name used during `add` and retry.
-
-If the proxy times out during startup, check the bridge log shown by
-`mcp status`. Cold `npx` launches can take longer than a warm command, so

+If `restart` reports a missing provider and the original credential is not

+retry.
 
-If the sandbox cannot reach `host.docker.internal`, the current v1 bridge stays
-fail-closed. It does not widen the proxy bind address beyond host loopback.
+If the sandbox cannot reach an MCP server hosted on the workstation, use the
+OpenShell host alias path that works for your runtime, such as

+that endpoint. Do not run a separate NemoClaw host proxy for MCP credentials.

 ## Source-of-Truth Boundaries
 
 - OpenShell gateway auth source contract: invalid state is an OpenShell `0.0.67` Docker-driver gateway launched from NemoClaw without the upstream config-file auth policy, local mTLS bundle, sandbox JWT bundle, or Docker bridge callback route that OpenShell expects. Source boundary is upstream OpenShell config/auth/listener/Docker-driver behavior; NemoClaw only generates config, local TLS/JWT material, bind policy, and launch env. Regression coverage is the live `openshell-gateway-auth-source-contract` scenario plus local config/env/launch tests. Remove the NemoClaw-local compatibility notes when OpenShell exposes a stable SDK/config contract that makes this generated config surface unnecessary.
+- Docker-hosted gateway compatibility container: invalid state is a host with older glibc than the downloaded `openshell-gateway` binary, where the gateway must run in a compatibility container but still behave like the host-side Docker-driver gateway. Source boundary is OpenShell Docker-driver bridge discovery plus Docker API access. NemoClaw uses `--network host` so OpenShell can bind the same Docker bridge callback addresses, mounts the Docker socket read/write so the gateway can drive the Docker compute driver, keeps the main listener on `127.0.0.1`, and publishes no additional container ports. Rootless Docker/Podman remain outside the accepted path for this shim until the OpenShell Docker driver publishes a supported rootless compatibility contract.
 - Markerless sandbox gateway recovery output: invalid state is newer OpenShell sandbox exec/relaunch output that starts the gateway launcher but omits NemoClaw's legacy `GATEWAY_PID=` or `ALREADY_RUNNING` markers. Source boundary is OpenShell exec/recovery output format; NemoClaw treats the text as "may have started" only and still requires a healthy gateway probe. Regression coverage lives in `test/cli/connect-recovery-markerless.test.ts`. Remove the markerless heuristic when OpenShell provides a stable machine-readable recovery marker.
 - Sessions admin gateway RPC helper: invalid state is a host CLI session reset/delete action that needs OpenClaw backend/operator scope while preserving gateway token, loopback, and auto-pair boundaries. Source boundary is OpenClaw's gateway-runtime API; NemoClaw's helper is limited to `sessions.reset` and `sessions.delete`. Regression coverage lives in `src/lib/actions/sandbox/sessions/gateway-rpc-call.test.ts`. Add new methods only with a caller, allowlist entry, and negative test.
 
@@ -39,7 +40,7 @@ NemoClaw generates an OpenShell gateway config with `gateway_jwt`, local TLS, mT
 
 The generated config sets `[openshell.gateway.tls]` with the NemoClaw-owned local server certificate, requires client certificates, enables `[openshell.gateway.mtls_auth]`, and provides Docker `guest_tls_ca`, `guest_tls_cert`, and `guest_tls_key` entries so supervisor-to-gateway callbacks use the same local CA. It also scrubs inherited `OPENSHELL_DISABLE_GATEWAY_AUTH=true` from host and compatibility-container launches.
 
-The Docker-hosted compatibility gateway keeps the main OpenShell listener on `127.0.0.1`. Sandbox callback reachability is preserved by OpenShell's Docker driver: it rewrites the sandbox-facing endpoint to `host.openshell.internal:<gateway-port>` and the OpenShell server adds the computed Docker bridge listener when that route is needed. `NEMOCLAW_OPENSHELL_GATEWAY_COMPAT_BIND_ADDRESS=0.0.0.0` is rejected so the main listener is not widened.

The compatibility container does not publish Docker ports; it uses host networking only for parity with the host gateway's Docker bridge listener calculation.
 
 Package-managed Docker-driver gateways also reject `NEMOCLAW_GATEWAY_BIND_ADDRESS=0.0.0.0` while the 0.0.67 Docker-driver config is active. Use the dashboard bind setting for remote dashboard exposure instead of widening the OpenShell gateway surface.

@@ -7,7 +7,7 @@ Scope: NemoClaw Docker-driver gateway config generated for OpenShell `0.0.67`.
 ## Source-of-Truth Boundaries
 
 - OpenShell gateway auth source contract: invalid state is an OpenShell `0.0.67` Docker-driver gateway launched from NemoClaw without the upstream config-file auth policy, local mTLS bundle, sandbox JWT bundle, or Docker bridge callback route that OpenShell expects. Source boundary is upstream OpenShell config/auth/listener/Docker-driver behavior; NemoClaw only generates config, local TLS/JWT material, bind policy, and launch env. Regression coverage is the live `openshell-gateway-auth-source-contract` scenario plus local config/env/launch tests. Remove the NemoClaw-local compatibility notes when OpenShell exposes a stable SDK/config contract that makes this generated config surface unnecessary.
-- Docker-hosted gateway compatibility container: invalid state is a host with older glibc than the downloaded `openshell-gateway` binary, where the gateway must run in a compatibility container but still behave like the host-side Docker-driver gateway. Source boundary is OpenShell Docker-driver bridge discovery plus Docker API access. NemoClaw uses `--network host` so OpenShell can bind the same Docker bridge callback addresses, mounts the Docker socket read/write so the gateway can drive the Docker compute driver, keeps the main listener on `127.0.0.1`, and publishes no additional container ports. Rootless Docker/Podman remain outside the accepted path for this shim until the OpenShell Docker driver publishes a supported rootless compatibility contract.
+- Docker-hosted gateway compatibility container: invalid state is a host with older glibc than the downloaded `openshell-gateway` binary, where the gateway must run in a compatibility container but still behave like the host-side Docker-driver gateway. Source boundary is OpenShell Docker-driver bridge discovery plus Docker API access. NemoClaw uses `--network host` so OpenShell can bind the same Docker bridge callback addresses, bind-mounts the Docker socket so the gateway can drive the Docker compute driver, keeps the main listener on `127.0.0.1`, drops Linux capabilities, sets `no-new-privileges`, and publishes no additional container ports. Rootless Docker/Podman remain outside the accepted path for this shim until the OpenShell Docker driver publishes a supported rootless compatibility contract.
 - Markerless sandbox gateway recovery output: invalid state is newer OpenShell sandbox exec/relaunch output that starts the gateway launcher but omits NemoClaw's legacy `GATEWAY_PID=` or `ALREADY_RUNNING` markers. Source boundary is OpenShell exec/recovery output format; NemoClaw treats the text as "may have started" only and still requires a healthy gateway probe. Regression coverage lives in `test/cli/connect-recovery-markerless.test.ts`. Remove the markerless heuristic when OpenShell provides a stable machine-readable recovery marker.
 - Sessions admin gateway RPC helper: invalid state is a host CLI session reset/delete action that needs OpenClaw backend/operator scope while preserving gateway token, loopback, and auto-pair boundaries. Source boundary is OpenClaw's gateway-runtime API; NemoClaw's helper is limited to `sessions.reset` and `sessions.delete`. Regression coverage lives in `src/lib/actions/sandbox/sessions/gateway-rpc-call.test.ts`. Add new methods only with a caller, allowlist entry, and negative test.

- * SSH shell cannot (test/e2e-gateway-isolation.sh test 13). Every

- * unconditionally, so the offending key (e.g. `TELEGRAM_BOT_TOKEN (line
- * N)`) and the reason for refusal always reach the operator, including
- * on the quiet probe/recover path. Returns `null` only when the persisted
- * sandbox registry entry is not Hermes (no boundary to enforce). When
- * the registry says Hermes but the in-memory agent definition failed to
- * load (`getSessionAgent()` returned `null` from its catch path), the
- * helper fails safe with an inconclusive refusal rather than silently
- * skipping the boundary. A running Hermes gateway whose root exec
- * channel is unreachable is also treated as a fail-safe inconclusive
- * refusal rather than a healthy path. Non-zero validator status without
- * a `SECRET_BOUNDARY_REFUSED` marker is reported as inconclusive, not as
- * a raw-secret refusal, so a shell or validator crash does not
- * masquerade as a poisoned env file.

@@ -7,7 +7,8 @@ Scope: NemoClaw Docker-driver gateway config generated for OpenShell `0.0.67`.
 ## Source-of-Truth Boundaries
 
 - OpenShell gateway auth source contract: invalid state is an OpenShell `0.0.67` Docker-driver gateway launched from NemoClaw without the upstream config-file auth policy, local mTLS bundle, sandbox JWT bundle, or Docker bridge callback route that OpenShell expects. Source boundary is upstream OpenShell config/auth/listener/Docker-driver behavior; NemoClaw only generates config, local TLS/JWT material, bind policy, and launch env. Regression coverage is the live `openshell-gateway-auth-source-contract` scenario plus local config/env/launch tests. Remove the NemoClaw-local compatibility notes when OpenShell exposes a stable SDK/config contract that makes this generated config surface unnecessary.
-- Docker-hosted gateway compatibility container: invalid state is a host with older glibc than the downloaded `openshell-gateway` binary, where the gateway must run in a compatibility container but still behave like the host-side Docker-driver gateway. Source boundary is OpenShell Docker-driver bridge discovery plus Docker API access. NemoClaw uses `--network host` so OpenShell can bind the same Docker bridge callback addresses, bind-mounts the Docker socket so the gateway can drive the Docker compute driver, keeps the main listener on `127.0.0.1`, drops Linux capabilities, sets `no-new-privileges`, and publishes no additional container ports. Rootless Docker/Podman remain outside the accepted path for this shim until the OpenShell Docker driver publishes a supported rootless compatibility contract.
+- Docker-hosted gateway compatibility container: invalid state is a host with older glibc than the downloaded `openshell-gateway` binary, where the gateway must run in a compatibility container but still behave like the host-side Docker-driver gateway. Source boundary is OpenShell Docker-driver bridge discovery plus Docker API access. NemoClaw uses `--network host` so OpenShell can bind the same Docker bridge callback addresses, bind-mounts the Docker socket so the gateway can drive the Docker compute driver, keeps the main listener on `127.0.0.1`, drops Linux capabilities, sets `no-new-privileges`, and publishes no additional container ports. This PR cannot republish OpenShell `0.0.67` gateway release assets or change the upstream host-support matrix; the source fix belongs in OpenShell packaging via static or older-glibc-compatible Linux gateway assets, or in a documented OpenShell policy that drops those older hosts. Regression coverage is the compatibility-container launch/config tests plus the live gateway auth source-contract scenario. Remove this shim when OpenShell publishes supported Linux gateway assets that launch directly on the accepted older-glibc hosts, or when NemoClaw intentionally drops those hosts. Rootless Docker/Podman remain outside the accepted path for this shim until the OpenShell Docker driver publishes a supported rootless compatibility contract.
+- Hermes env-file secret-boundary enforcement: invalid state is a Hermes sandbox recovery path that restarts or accepts a running gateway while `/sandbox/.hermes/.env` contains raw secret-shaped values that the Hermes startup validator would reject. Source boundary is the Hermes image entrypoint and `validate-hermes-env-secret-boundary.py`; NemoClaw only re-runs that source validator on recovery/probe paths that bypass the entrypoint. This PR cannot retroactively bake the validator into already-created older Hermes sandbox images, so the missing-validator path remains warning-only for compatibility while current images keep the validator in the source image. Regression coverage lives in `src/lib/actions/sandbox/hermes-secret-boundary-recovery.test.ts`, `src/lib/agent/runtime-hermes-secret-boundary-shape.test.ts`, and `src/lib/agent/runtime-hermes-secret-boundary-behavioural.test.ts`. Remove the NemoClaw recovery-side shim when Hermes exposes a stable recovery entrypoint that always re-enters the validator, and flip the missing-validator branch fail-closed once the minimum supported Hermes image is guaranteed to include the validator.
 - Markerless sandbox gateway recovery output: invalid state is newer OpenShell sandbox exec/relaunch output that starts the gateway launcher but omits NemoClaw's legacy `GATEWAY_PID=` or `ALREADY_RUNNING` markers. Source boundary is OpenShell exec/recovery output format; NemoClaw treats the text as "may have started" only and still requires a healthy gateway probe. Regression coverage lives in `test/cli/connect-recovery-markerless.test.ts`. Remove the markerless heuristic when OpenShell provides a stable machine-readable recovery marker.
 - Sessions admin gateway RPC helper: invalid state is a host CLI session reset/delete action that needs OpenClaw backend/operator scope while preserving gateway token, loopback, and auto-pair boundaries. Source boundary is OpenClaw's gateway-runtime API; NemoClaw's helper is limited to `sessions.reset` and `sessions.delete`. Regression coverage lives in `src/lib/actions/sandbox/sessions/gateway-rpc-call.test.ts`. Add new methods only with a caller, allowlist entry, and negative test.

 | Risk if relaxed | Other hosts on the network may be able to reach the OpenShell gateway. Docker-driver gateways on OpenShell 0.0.67 reject wildcard gateway binds while gateway JWT auth is active. |
 | Recommendation | Keep the gateway loopback default and expose only the dashboard forward when remote access is needed. |
 
+### Gateway Compatibility Container
+
+On Linux hosts whose glibc is older than the OpenShell gateway binary requires, NemoClaw can run `openshell-gateway` in a Docker compatibility container so the Docker-driver gateway still starts.
+
+| Aspect | Detail |
+|---|---|
+| Default | The compatibility container keeps the main gateway listener on `127.0.0.1`, uses host networking so OpenShell computes the same Docker bridge callback addresses as a host-side gateway, mounts the Docker socket read-only, drops Linux capabilities, sets `no-new-privileges`, and publishes no extra Docker ports. |
+| What you can change | Disable the compatibility path with `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=0`, or run on a host/OpenShell build combination where the gateway binary launches directly. |
+| Risk if relaxed | The Docker socket remains a privileged host API even when bind-mounted read-only. Treat this mode as equivalent to trusting the host user that can drive Docker, and do not enable it on untrusted shared hosts. |
+| Recommendation | Prefer a directly supported OpenShell gateway binary or host glibc level. Use the compatibility container only as a local upgrade bridge for trusted hosts that still need the OpenShell 0.0.67 Docker-driver gateway. |
+
 ### Insecure Auth Derivation
 
 The `allowInsecureAuth` setting controls whether the gateway permits non-HTTPS authentication.

@@ -41,6 +41,8 @@ NemoClaw generates an OpenShell gateway config with `gateway_jwt`, local TLS, mT
 
 The generated config sets `[openshell.gateway.tls]` with the NemoClaw-owned local server certificate, requires client certificates, enables `[openshell.gateway.mtls_auth]`, and provides Docker `guest_tls_ca`, `guest_tls_cert`, and `guest_tls_key` entries so supervisor-to-gateway callbacks use the same local CA. It also scrubs inherited `OPENSHELL_DISABLE_GATEWAY_AUTH=true` from host and compatibility-container launches.
 
+The local TLS reuse check allows a fixed 5-minute certificate validity skew to absorb normal host/container clock drift while still regenerating bundles outside that bounded window; the bound is intentionally not environment-overridable for this release so deployments cannot silently widen the local mTLS acceptance window. The sandbox JWT config uses OpenShell's `ttl_secs = 3600` gateway contract: short enough for local sandbox callbacks, long enough to avoid unnecessary re-mint churn during normal Docker-driver operations, and covered by the upstream OpenShell sandbox JWT expiry tests plus NemoClaw config-auth contract tests.
+
 The Docker-hosted compatibility gateway keeps the main OpenShell listener on `127.0.0.1`. Sandbox callback reachability is preserved by OpenShell's Docker driver: it rewrites the sandbox-facing endpoint to `host.openshell.internal:<gateway-port>` and the OpenShell server adds the computed Docker bridge listener when that route is needed. `NEMOCLAW_OPENSHELL_GATEWAY_COMPAT_BIND_ADDRESS=0.0.0.0` is rejected so the main listener is not widened. The compatibility container does not publish Docker ports; it uses host networking only for parity with the host gateway's Docker bridge listener calculation.
 
 Package-managed Docker-driver gateways also reject `NEMOCLAW_GATEWAY_BIND_ADDRESS=0.0.0.0` while the 0.0.67 Docker-driver config is active. Use the dashboard bind setting for remote dashboard exposure instead of widening the OpenShell gateway surface.

+On Linux hosts whose glibc is older than the OpenShell gateway binary requires, NemoClaw can run `openshell-gateway` in a Docker compatibility container so the Docker-driver gateway still starts. This path requires the explicit opt-in `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1`.
 
 | Aspect | Detail |
 |---|---|
-| Default | The compatibility container keeps the main gateway listener on `127.0.0.1`, uses host networking so OpenShell computes the same Docker bridge callback addresses as a host-side gateway, mounts the Docker socket read-only, drops Linux capabilities, sets `no-new-privileges`, and publishes no extra Docker ports. |
-| What you can change | Disable the compatibility path with `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=0`, or run on a host/OpenShell build combination where the gateway binary launches directly. |
+| Default | NemoClaw does not auto-enable the compatibility container on ABI mismatch. If `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1` is set, the container keeps the main gateway listener on `127.0.0.1`, uses host networking so OpenShell computes the same Docker bridge callback addresses as a host-side gateway, mounts the Docker socket read-only, drops Linux capabilities, sets `no-new-privileges`, and publishes no extra Docker ports. |

 | Risk if relaxed | The Docker socket remains a privileged host API even when bind-mounted read-only. Treat this mode as equivalent to trusting the host user that can drive Docker, and do not enable it on untrusted shared hosts. |
 | Recommendation | Prefer a directly supported OpenShell gateway binary or host glibc level. Use the compatibility container only as a local upgrade bridge for trusted hosts that still need the OpenShell 0.0.67 Docker-driver gateway. |

 ## Source-of-Truth Boundaries
 
 - OpenShell gateway auth source contract: invalid state is an OpenShell `0.0.67` Docker-driver gateway launched from NemoClaw without the upstream config-file auth policy, local mTLS bundle, sandbox JWT bundle, or Docker bridge callback route that OpenShell expects. Source boundary is upstream OpenShell config/auth/listener/Docker-driver behavior; NemoClaw only generates config, local TLS/JWT material, bind policy, and launch env. Regression coverage is the live `openshell-gateway-auth-source-contract` scenario plus local config/env/launch tests. Remove the NemoClaw-local compatibility notes when OpenShell exposes a stable SDK/config contract that makes this generated config surface unnecessary.
-- Docker-hosted gateway compatibility container: invalid state is a host with older glibc than the downloaded `openshell-gateway` binary, where the gateway must run in a compatibility container but still behave like the host-side Docker-driver gateway. Source boundary is OpenShell Docker-driver bridge discovery plus Docker API access. NemoClaw uses `--network host` so OpenShell can bind the same Docker bridge callback addresses, bind-mounts the Docker socket so the gateway can drive the Docker compute driver, keeps the main listener on `127.0.0.1`, drops Linux capabilities, sets `no-new-privileges`, and publishes no additional container ports. This PR cannot republish OpenShell `0.0.67` gateway release assets or change the upstream host-support matrix; the source fix belongs in OpenShell packaging via static or older-glibc-compatible Linux gateway assets, or in a documented OpenShell policy that drops those older hosts. Regression coverage is the compatibility-container launch/config tests plus the live gateway auth source-contract scenario. Remove this shim when OpenShell publishes supported Linux gateway assets that launch directly on the accepted older-glibc hosts, or when NemoClaw intentionally drops those hosts. Rootless Docker/Podman remain outside the accepted path for this shim until the OpenShell Docker driver publishes a supported rootless compatibility contract.
+- Docker-hosted gateway compatibility container: invalid state is a host with older glibc than the downloaded `openshell-gateway` binary, where the gateway needs an explicitly opted-in compatibility container but still behaves like the host-side Docker-driver gateway.

 - Hermes env-file secret-boundary enforcement: invalid state is a Hermes sandbox recovery path that restarts or accepts a running gateway while `/sandbox/.hermes/.env` contains raw secret-shaped values that the Hermes startup validator would reject. Source boundary is the Hermes image entrypoint and `validate-hermes-env-secret-boundary.py`; NemoClaw only re-runs that source validator on recovery/probe paths that bypass the entrypoint. This PR cannot retroactively bake the validator into already-created older Hermes sandbox images, so the missing-validator path remains warning-only for compatibility while current images keep the validator in the source image. Regression coverage lives in `src/lib/actions/sandbox/hermes-secret-boundary-recovery.test.ts`, `src/lib/agent/runtime-hermes-secret-boundary-shape.test.ts`, and `src/lib/agent/runtime-hermes-secret-boundary-behavioural.test.ts`. Remove the NemoClaw recovery-side shim when Hermes exposes a stable recovery entrypoint that always re-enters the validator, and flip the missing-validator branch fail-closed once the minimum supported Hermes image is guaranteed to include the validator.
 - Markerless sandbox gateway recovery output: invalid state is newer OpenShell sandbox exec/relaunch output that starts the gateway launcher but omits NemoClaw's legacy `GATEWAY_PID=` or `ALREADY_RUNNING` markers. Source boundary is OpenShell exec/recovery output format; NemoClaw treats the text as "may have started" only and still requires a healthy gateway probe. Regression coverage lives in `test/cli/connect-recovery-markerless.test.ts`. Remove the markerless heuristic when OpenShell provides a stable machine-readable recovery marker.
 - Sessions admin gateway RPC helper: invalid state is a host CLI session reset/delete action that needs OpenClaw backend/operator scope while preserving gateway token, loopback, and auto-pair boundaries. Source boundary is OpenClaw's gateway-runtime API; NemoClaw's helper is limited to `sessions.reset` and `sessions.delete`. Regression coverage lives in `src/lib/actions/sandbox/sessions/gateway-rpc-call.test.ts`. Add new methods only with a caller, allowlist entry, and negative test.

 The local TLS reuse check allows a fixed 5-minute certificate validity skew to absorb normal host/container clock drift while still regenerating bundles outside that bounded window; the bound is intentionally not environment-overridable for this release so deployments cannot silently widen the local mTLS acceptance window. The sandbox JWT config uses OpenShell's `ttl_secs = 3600` gateway contract: short enough for local sandbox callbacks, long enough to avoid unnecessary re-mint churn during normal Docker-driver operations, and covered by the upstream OpenShell sandbox JWT expiry tests plus NemoClaw config-auth contract tests.
 
-The Docker-hosted compatibility gateway keeps the main OpenShell listener on `127.0.0.1`.

@@ -8,7 +8,7 @@ Scope: NemoClaw Docker-driver gateway config generated for OpenShell `0.0.67`.
 
 - OpenShell gateway auth source contract: invalid state is an OpenShell `0.0.67` Docker-driver gateway launched from NemoClaw without the upstream config-file auth policy, local mTLS bundle, sandbox JWT bundle, or Docker bridge callback route that OpenShell expects. Source boundary is upstream OpenShell config/auth/listener/Docker-driver behavior; NemoClaw only generates config, local TLS/JWT material, bind policy, and launch env. Regression coverage is the live `openshell-gateway-auth-source-contract` scenario plus local config/env/launch tests. Remove the NemoClaw-local compatibility notes when OpenShell exposes a stable SDK/config contract that makes this generated config surface unnecessary.
 - Docker-hosted gateway compatibility container: invalid state is a host with older glibc than the downloaded `openshell-gateway` binary, where the gateway needs an explicitly opted-in compatibility container but still behaves like the host-side Docker-driver gateway. Source boundary is OpenShell Docker-driver bridge discovery plus Docker API access. NemoClaw requires `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1` before using `--network host`, so OpenShell can bind the same Docker bridge callback addresses, and before bind-mounting the Docker socket so the gateway can drive the Docker compute driver. The container keeps the main listener on `127.0.0.1`, drops Linux capabilities, sets `no-new-privileges`, and publishes no additional container ports. This PR cannot republish OpenShell `0.0.67` gateway release assets or change the upstream host-support matrix; the source fix belongs in OpenShell packaging via static or older-glibc-compatible Linux gateway assets, or in a documented OpenShell policy that drops those older hosts. Regression coverage is the compatibility-container launch/config tests plus the live gateway auth source-contract scenario. Remove this shim when OpenShell publishes supported Linux gateway assets that launch directly on the accepted older-glibc hosts, or when NemoClaw intentionally drops those hosts. Rootless Docker/Podman remain outside the accepted path for this shim until the OpenShell Docker driver publishes a supported rootless compatibility contract.
-- Hermes env-file secret-boundary enforcement: invalid state is a Hermes sandbox recovery path that restarts or accepts a running gateway while `/sandbox/.hermes/.env` contains raw secret-shaped values that the Hermes startup validator would reject. Source boundary is the Hermes image entrypoint and `validate-hermes-env-secret-boundary.py`; NemoClaw only re-runs that source validator on recovery/probe paths that bypass the entrypoint. This PR cannot retroactively bake the validator into already-created older Hermes sandbox images, so the missing-validator path remains warning-only for compatibility while current images keep the validator in the source image. Regression coverage lives in `src/lib/actions/sandbox/hermes-secret-boundary-recovery.test.ts`, `src/lib/agent/runtime-hermes-secret-boundary-shape.test.ts`, and `src/lib/agent/runtime-hermes-secret-boundary-behavioural.test.ts`. Remove the NemoClaw recovery-side shim when Hermes exposes a stable recovery entrypoint that always re-enters the validator, and flip the missing-validator branch fail-closed once the minimum supported Hermes image is guaranteed to include the validator.
+- Hermes env-file secret-boundary enforcement: invalid state is a Hermes sandbox recovery path that restarts or accepts a running gateway while `/sandbox/.hermes/.env` contains raw secret-shaped values that the Hermes startup validator would reject. Source boundary is the Hermes image entrypoint and `validate-hermes-env-secret-boundary.py`; NemoClaw only re-runs that source validator on recovery/probe paths that bypass the entrypoint. This PR cannot retroactively bake the validator into already-created older Hermes sandbox images, so missing-validator recovery now fails closed with a re-image instruction instead of claiming the boundary was checked. Regression coverage lives in `src/lib/actions/sandbox/hermes-secret-boundary-recovery.test.ts`, `src/lib/agent/runtime-hermes-secret-boundary-shape.test.ts`, and `src/lib/agent/runtime-hermes-secret-boundary-behavioural.test.ts`. Remove the NemoClaw recovery-side shim when Hermes exposes a stable recovery entrypoint that always re-enters the validator.
 - Markerless sandbox gateway recovery output: invalid state is newer OpenShell sandbox exec/relaunch output that starts the gateway launcher but omits NemoClaw's legacy `GATEWAY_PID=` or `ALREADY_RUNNING` markers. Source boundary is OpenShell exec/recovery output format; NemoClaw treats the text as "may have started" only and still requires a healthy gateway probe. Regression coverage lives in `test/cli/connect-recovery-markerless.test.ts`. Remove the markerless heuristic when OpenShell provides a stable machine-readable recovery marker.
 - Sessions admin gateway RPC helper: invalid state is a host CLI session reset/delete action that needs OpenClaw backend/operator scope while preserving gateway token, loopback, and auto-pair boundaries. Source boundary is OpenClaw's gateway-runtime API; NemoClaw's helper is limited to `sessions.reset` and `sessions.delete`. Regression coverage lives in `src/lib/actions/sandbox/sessions/gateway-rpc-call.test.ts`. Add new methods only with a caller, allowlist entry, and negative test.

 Use this page to track the highlights of the latest release.
 For more detailed release notes, refer to the [NemoClaw GitHub announcements](https://github.com/NVIDIA/NemoClaw/discussions/categories/announcements?discussions_q=is%3Aopen+category%3AAnnouncements).
 
+## v0.0.70
+
+NemoClaw v0.0.70 hardens OpenShell gateway auth and Hermes recovery behavior:
+
+- OpenShell `0.0.67` Docker-driver gateway setup now generates and validates the local mTLS/JWT auth bundle more defensively, keeps the older-glibc compatibility container behind an explicit opt-in, and limits the live gateway auth contract job to explicit workflow dispatches pinned to OpenShell `0.0.67`.
+  For more information, refer to [OpenShell 0.0.67 Gateway Auth Review](../security/openshell-0.0.67-gateway-auth-review) and [Security Best Practices](../security/best-practices).
+- Hermes recovery now fails closed when an older sandbox image is missing the secret-boundary validator needed to re-check `/sandbox/.hermes/.env`.
+  The command refuses recovery, stops Hermes gateway/dashboard processes, prints a re-image instruction, and requires rebuilding the sandbox with a current Hermes image before retrying recovery.
+  For more information, refer to [Troubleshooting](../reference/troubleshooting) and [NemoClaw CLI Commands Reference](../reference/commands).
+
 ## v0.0.68
 
 NemoClaw v0.0.68 improves onboarding recovery, messaging setup, agent-specific CLI behavior, local inference defaults, and release validation:

 NemoClaw v0.0.70 hardens OpenShell gateway auth and Hermes recovery behavior:
 
-- OpenShell `0.0.67` Docker-driver gateway setup now generates and validates the local mTLS/JWT auth bundle more defensively, keeps the older-glibc compatibility container behind an explicit opt-in, and limits the live gateway auth contract job to explicit workflow dispatches pinned to OpenShell `0.0.67`.
-  For more information, refer to [OpenShell 0.0.67 Gateway Auth Review](../security/openshell-0.0.67-gateway-auth-review) and [Security Best Practices](../security/best-practices).
+- OpenShell `0.0.71` Docker-driver gateway setup now generates and validates the local mTLS/JWT auth bundle more defensively, keeps the older-glibc compatibility container behind an explicit opt-in, and limits the live gateway auth contract job to explicit workflow dispatches pinned to OpenShell `0.0.71`.
+  For more information, refer to [OpenShell 0.0.71 Gateway Auth Review](../security/openshell-0.0.71-gateway-auth-review) and [Security Best Practices](../security/best-practices).
 - Hermes recovery now fails closed when an older sandbox image is missing the secret-boundary validator needed to re-check `/sandbox/.hermes/.env`.
   The command refuses recovery, stops Hermes gateway/dashboard processes, prints a re-image instruction, and requires rebuilding the sandbox with a current Hermes image before retrying recovery.
   For more information, refer to [Troubleshooting](../reference/troubleshooting) and [NemoClaw CLI Commands Reference](../reference/commands).

 ## Source-of-Truth Boundaries
 
-- OpenShell gateway auth source contract: invalid state is an OpenShell `0.0.67` Docker-driver gateway launched from NemoClaw without the upstream config-file auth policy, local mTLS bundle, sandbox JWT bundle, or Docker bridge callback route that OpenShell expects. Source boundary is upstream OpenShell config/auth/listener/Docker-driver behavior; NemoClaw only generates config, local TLS/JWT material, bind policy, and launch env. Regression coverage is the live `openshell-gateway-auth-source-contract` scenario plus local config/env/launch tests. Remove the NemoClaw-local compatibility notes when OpenShell exposes a stable SDK/config contract that makes this generated config surface unnecessary.
-- Docker-hosted gateway compatibility container: invalid state is a host with older glibc than the downloaded `openshell-gateway` binary, where the gateway needs an explicitly opted-in compatibility container but still behaves like the host-side Docker-driver gateway. Source boundary is OpenShell Docker-driver bridge discovery plus Docker API access. NemoClaw requires `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1` before using `--network host`, so OpenShell can bind the same Docker bridge callback addresses, and before bind-mounting the Docker socket so the gateway can drive the Docker compute driver. The container keeps the main listener on `127.0.0.1`, drops Linux capabilities, sets `no-new-privileges`, and publishes no additional container ports. This PR cannot republish OpenShell `0.0.67` gateway release assets or change the upstream host-support matrix; the source fix belongs in OpenShell packaging via static or older-glibc-compatible Linux gateway assets, or in a documented OpenShell policy that drops those older hosts. Regression coverage is the compatibility-container launch/config tests plus the live gateway auth source-contract scenario. Remove this shim when OpenShell publishes supported Linux gateway assets that launch directly on the accepted older-glibc hosts, or when NemoClaw intentionally drops those hosts. Rootless Docker/Podman remain outside the accepted path for this shim until the OpenShell Docker driver publishes a supported rootless compatibility contract.

Remove the NemoClaw-local compatibility notes when OpenShell exposes a stable SDK/config contract that makes this generated config surface unnecessary.
+- Docker-hosted gateway compatibility container: OpenShell `0.0.68` lowered the standalone Linux gateway's glibc floor to `2.28`, and `0.0.71` carries that support. Supported Ubuntu 20.04+, RHEL/Rocky 8+, Amazon Linux 2023+, and Fedora 32+ hosts therefore launch the gateway directly. NemoClaw retains the existing container bridge only as an explicit opt-in for an older host below the upstream support floor or a forced diagnostic run. `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1` is still required before using `--network host` and read-only Docker socket access. The container keeps the main listener on `127.0.0.1`, drops Linux capabilities, sets `no-new-privileges`, and publishes no additional Docker ports. This fallback does not extend OpenShell's supported host matrix. Regression coverage is the compatibility-container launch/config tests plus the live gateway auth source-contract scenario. Rootless Docker/Podman remain outside the accepted path for this shim until the OpenShell Docker driver publishes a supported rootless compatibility contract.
 - Hermes env-file secret-boundary enforcement: invalid state is a Hermes sandbox recovery path that restarts or accepts a running gateway while `/sandbox/.hermes/.env` contains raw secret-shaped values that the Hermes startup validator would reject. Source boundary is the Hermes image entrypoint and `validate-hermes-env-secret-boundary.py`; NemoClaw only re-runs that source validator on recovery/probe paths that bypass the entrypoint. This PR cannot retroactively bake the validator into already-created older Hermes sandbox images, so missing-validator recovery now fails closed with a re-image instruction instead of claiming the boundary was checked. Regression coverage lives in `src/lib/actions/sandbox/hermes-secret-boundary-recovery.test.ts`, `src/lib/agent/runtime-hermes-secret-boundary-shape.test.ts`, and `src/lib/agent/runtime-hermes-secret-boundary-behavioural.test.ts`. Remove the NemoClaw recovery-side shim when Hermes exposes a stable recovery entrypoint that always re-enters the validator.
 - Markerless sandbox gateway recovery output: invalid state is newer OpenShell sandbox exec/relaunch output that starts the gateway launcher but omits NemoClaw's legacy `GATEWAY_PID=` or `ALREADY_RUNNING` markers. Source boundary is OpenShell exec/recovery output format; NemoClaw treats the text as "may have started" only and still requires a healthy gateway probe. Regression coverage lives in `test/cli/connect-recovery-markerless.test.ts`. Remove the markerless heuristic when OpenShell provides a stable machine-readable recovery marker.
 - Sessions admin gateway RPC helper: invalid state is a host CLI session reset/delete action that needs OpenClaw backend/operator scope while preserving gateway token, loopback, and auto-pair boundaries. Source boundary is OpenClaw's gateway-runtime API; NemoClaw's helper is limited to `sessions.reset` and `sessions.delete`. Regression coverage lives in `src/lib/actions/sandbox/sessions/gateway-rpc-call.test.ts`. Add new methods only with a caller, allowlist entry, and negative test.

 The Docker-hosted compatibility gateway requires `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1` and keeps the main OpenShell listener on `127.0.0.1`. Sandbox callback reachability is preserved by OpenShell's Docker driver: it rewrites the sandbox-facing endpoint to `host.openshell.internal:<gateway-port>` and the OpenShell server adds the computed Docker bridge listener when that route is needed. `NEMOCLAW_OPENSHELL_GATEWAY_COMPAT_BIND_ADDRESS=0.0.0.0` is rejected so the main listener is not widened. The compatibility container does not publish Docker ports; it uses host networking only for parity with the host gateway's Docker bridge listener calculation after explicit opt-in.

@@ -9,6 +9,7 @@ Scope: NemoClaw Docker-driver gateway config generated for OpenShell `0.0.71`.
 - OpenShell gateway auth source contract: invalid state is an OpenShell `0.0.71` Docker-driver gateway launched from NemoClaw without the upstream config-file auth policy, local mTLS bundle, sandbox JWT bundle, or Docker bridge callback route that OpenShell expects. Source boundary is upstream OpenShell config/auth/listener/Docker-driver behavior; NemoClaw only generates config, local TLS/JWT material, bind policy, and launch env. Regression coverage is the live `openshell-gateway-auth-source-contract` scenario plus local config/env/launch tests. Remove the NemoClaw-local compatibility notes when OpenShell exposes a stable SDK/config contract that makes this generated config surface unnecessary.
 - Docker-hosted gateway compatibility container: OpenShell `0.0.68` lowered the standalone Linux gateway's glibc floor to `2.28`, and `0.0.71` carries that support. Supported Ubuntu 20.04+, RHEL/Rocky 8+, Amazon Linux 2023+, and Fedora 32+ hosts therefore launch the gateway directly. NemoClaw retains the existing container bridge only as an explicit opt-in for an older host below the upstream support floor or a forced diagnostic run. `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1` is still required before using `--network host` and read-only Docker socket access. The container keeps the main listener on `127.0.0.1`, drops Linux capabilities, sets `no-new-privileges`, and publishes no additional Docker ports. This fallback does not extend OpenShell's supported host matrix. Regression coverage is the compatibility-container launch/config tests plus the live gateway auth source-contract scenario. Rootless Docker/Podman remain outside the accepted path for this shim until the OpenShell Docker driver publishes a supported rootless compatibility contract.
 - Hermes env-file secret-boundary enforcement: invalid state is a Hermes sandbox recovery path that restarts or accepts a running gateway while `/sandbox/.hermes/.env` contains raw secret-shaped values that the Hermes startup validator would reject. Source boundary is the Hermes image entrypoint and `validate-hermes-env-secret-boundary.py`; NemoClaw only re-runs that source validator on recovery/probe paths that bypass the entrypoint. This PR cannot retroactively bake the validator into already-created older Hermes sandbox images, so missing-validator recovery now fails closed with a re-image instruction instead of claiming the boundary was checked. Regression coverage lives in `src/lib/actions/sandbox/hermes-secret-boundary-recovery.test.ts`, `src/lib/agent/runtime-hermes-secret-boundary-shape.test.ts`, and `src/lib/agent/runtime-hermes-secret-boundary-behavioural.test.ts`. Remove the NemoClaw recovery-side shim when Hermes exposes a stable recovery entrypoint that always re-enters the validator.
+- Gateway JWT generation lock recovery: invalid state is a crashed NemoClaw process leaving `.jwt-generating` behind after taking the exclusive host-side bundle-generation lock. The source boundary is NemoClaw's own atomic JWT bundle writer; OpenShell consumes the resulting paths but does not own this lock, so the source fix belongs here. A lock is removed only when it contains a numeric owner PID that the operating system reports as absent, and a per-acquisition nonce prevents a replaced lock from being mistaken for the observed owner. Malformed or unprobeable locks continue to fail closed. Regression coverage lives in `src/lib/onboard/docker-driver-gateway-jwt-bundle.test.ts`. Remove the lock and its recovery together if JWT bundle generation moves into OpenShell or to an OS-backed locking primitive.
 - Markerless sandbox gateway recovery output: invalid state is newer OpenShell sandbox exec/relaunch output that starts the gateway launcher but omits NemoClaw's legacy `GATEWAY_PID=` or `ALREADY_RUNNING` markers. Source boundary is OpenShell exec/recovery output format; NemoClaw treats the text as "may have started" only and still requires a healthy gateway probe. Regression coverage lives in `test/cli/connect-recovery-markerless.test.ts`. Remove the markerless heuristic when OpenShell provides a stable machine-readable recovery marker.
 - Sessions admin gateway RPC helper: invalid state is a host CLI session reset/delete action that needs OpenClaw backend/operator scope while preserving gateway token, loopback, and auto-pair boundaries. Source boundary is OpenClaw's gateway-runtime API; NemoClaw's helper is limited to `sessions.reset` and `sessions.delete`. Regression coverage lives in `src/lib/actions/sandbox/sessions/gateway-rpc-call.test.ts`. Add new methods only with a caller, allowlist entry, and negative test.

@@ -7,7 +7,7 @@ Scope: NemoClaw Docker-driver gateway config generated for OpenShell `0.0.71`.
 ## Source-of-Truth Boundaries
 
 - OpenShell gateway auth source contract: invalid state is an OpenShell `0.0.71` Docker-driver gateway launched from NemoClaw without the upstream config-file auth policy, local mTLS bundle, sandbox JWT bundle, or Docker bridge callback route that OpenShell expects. Source boundary is upstream OpenShell config/auth/listener/Docker-driver behavior; NemoClaw only generates config, local TLS/JWT material, bind policy, and launch env. Regression coverage is the live `openshell-gateway-auth-source-contract` scenario plus local config/env/launch tests. Remove the NemoClaw-local compatibility notes when OpenShell exposes a stable SDK/config contract that makes this generated config surface unnecessary.
-- Docker-hosted gateway compatibility container: OpenShell `0.0.68` lowered the standalone Linux gateway's glibc floor to `2.28`, and `0.0.71` carries that support. Supported Ubuntu 20.04+, RHEL/Rocky 8+, Amazon Linux 2023+, and Fedora 32+ hosts therefore launch the gateway directly. NemoClaw retains the existing container bridge only as an explicit opt-in for an older host below the upstream support floor or a forced diagnostic run. `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1` is still required before using `--network host` and read-only Docker socket access. The container keeps the main listener on `127.0.0.1`, drops Linux capabilities, sets `no-new-privileges`, and publishes no additional Docker ports. This fallback does not extend OpenShell's supported host matrix. Regression coverage is the compatibility-container launch/config tests plus the live gateway auth source-contract scenario. Rootless Docker/Podman remain outside the accepted path for this shim until the OpenShell Docker driver publishes a supported rootless compatibility contract.

The container keeps the main listener on `127.0.0.1`, drops Linux capabilities, sets `no-new-privileges`, and publishes no additional Docker ports. The production onboarding path emits this trust boundary through `console.warn`. This fallback does not extend OpenShell's supported host matrix. Regression coverage is the compatibility-container launch/config tests plus the live gateway auth source-contract scenario. Rootless Docker/Podman remain outside the accepted path for this shim until the OpenShell Docker driver publishes a supported rootless compatibility contract.
 - Hermes env-file secret-boundary enforcement: invalid state is a Hermes sandbox recovery path that restarts or accepts a running gateway while `/sandbox/.hermes/.env` contains raw secret-shaped values that the Hermes startup validator would reject. Source boundary is the Hermes image entrypoint and `validate-hermes-env-secret-boundary.py`; NemoClaw only re-runs that source validator on recovery/probe paths that bypass the entrypoint. This PR cannot retroactively bake the validator into already-created older Hermes sandbox images, so missing-validator recovery now fails closed with a re-image instruction instead of claiming the boundary was checked. Regression coverage lives in `src/lib/actions/sandbox/hermes-secret-boundary-recovery.test.ts`, `src/lib/agent/runtime-hermes-secret-boundary-shape.test.ts`, and `src/lib/agent/runtime-hermes-secret-boundary-behavioural.test.ts`. Remove the NemoClaw recovery-side shim when Hermes exposes a stable recovery entrypoint that always re-enters the validator.
 - Gateway JWT generation lock recovery: invalid state is a crashed NemoClaw process leaving `.jwt-generating` behind after taking the exclusive host-side bundle-generation lock. The source boundary is NemoClaw's own atomic JWT bundle writer; OpenShell consumes the resulting paths but does not own this lock, so the source fix belongs here. A lock is removed only when it contains a numeric owner PID that the operating system reports as absent, and a per-acquisition nonce prevents a replaced lock from being mistaken for the observed owner. Malformed or unprobeable locks continue to fail closed. Regression coverage lives in `src/lib/onboard/docker-driver-gateway-jwt-bundle.test.ts`. Remove the lock and its recovery together if JWT bundle generation moves into OpenShell or to an OS-backed locking primitive.
 - Markerless sandbox gateway recovery output: invalid state is newer OpenShell sandbox exec/relaunch output that starts the gateway launcher but omits NemoClaw's legacy `GATEWAY_PID=` or `ALREADY_RUNNING` markers. Source boundary is OpenShell exec/recovery output format; NemoClaw treats the text as "may have started" only and still requires a healthy gateway probe. Regression coverage lives in `test/cli/connect-recovery-markerless.test.ts`. Remove the markerless heuristic when OpenShell provides a stable machine-readable recovery marker.

@@ -9,7 +9,7 @@ Scope: NemoClaw Docker-driver gateway config generated for OpenShell `0.0.71`.
 - OpenShell gateway auth source contract: invalid state is an OpenShell `0.0.71` Docker-driver gateway launched from NemoClaw without the upstream config-file auth policy, local mTLS bundle, sandbox JWT bundle, or Docker bridge callback route that OpenShell expects. Source boundary is upstream OpenShell config/auth/listener/Docker-driver behavior; NemoClaw only generates config, local TLS/JWT material, bind policy, and launch env. Regression coverage is the live `openshell-gateway-auth-source-contract` scenario plus local config/env/launch tests. Remove the NemoClaw-local compatibility notes when OpenShell exposes a stable SDK/config contract that makes this generated config surface unnecessary.
 - Docker-hosted gateway compatibility container: OpenShell `0.0.68` lowered the standalone Linux gateway's glibc floor to `2.28`, and `0.0.71` carries that support. Supported Ubuntu 20.04+, RHEL/Rocky 8+, Amazon Linux 2023+, and Fedora 32+ hosts therefore launch the gateway directly. NemoClaw retains the existing container bridge only as an explicit opt-in for an older host below the upstream support floor or a forced diagnostic run. `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1` is still required before using `--network host` and read-only Docker socket access. The container keeps the main listener on `127.0.0.1`, drops Linux capabilities, sets `no-new-privileges`, and publishes no additional Docker ports. The production onboarding path emits this trust boundary through `console.warn`. This fallback does not extend OpenShell's supported host matrix. Regression coverage is the compatibility-container launch/config tests plus the live gateway auth source-contract scenario. Rootless Docker/Podman remain outside the accepted path for this shim until the OpenShell Docker driver publishes a supported rootless compatibility contract.
 - Hermes env-file secret-boundary enforcement: invalid state is a Hermes sandbox recovery path that restarts or accepts a running gateway while `/sandbox/.hermes/.env` contains raw secret-shaped values that the Hermes startup validator would reject. Source boundary is the Hermes image entrypoint and `validate-hermes-env-secret-boundary.py`; NemoClaw only re-runs that source validator on recovery/probe paths that bypass the entrypoint. This PR cannot retroactively bake the validator into already-created older Hermes sandbox images, so missing-validator recovery now fails closed with a re-image instruction instead of claiming the boundary was checked. Regression coverage lives in `src/lib/actions/sandbox/hermes-secret-boundary-recovery.test.ts`, `src/lib/agent/runtime-hermes-secret-boundary-shape.test.ts`, and `src/lib/agent/runtime-hermes-secret-boundary-behavioural.test.ts`. Remove the NemoClaw recovery-side shim when Hermes exposes a stable recovery entrypoint that always re-enters the validator.
-- Gateway JWT generation lock recovery: invalid state is a crashed NemoClaw process leaving `.jwt-generating` behind after taking the exclusive host-side bundle-generation lock. The source boundary is NemoClaw's own atomic JWT bundle writer; OpenShell consumes the resulting paths but does not own this lock, so the source fix belongs here. A lock is removed only when it contains a numeric owner PID that the operating system reports as absent, and a per-acquisition nonce prevents a replaced lock from being mistaken for the observed owner. Malformed or unprobeable locks continue to fail closed. Regression coverage lives in `src/lib/onboard/docker-driver-gateway-jwt-bundle.test.ts`. Remove the lock and its recovery together if JWT bundle generation moves into OpenShell or to an OS-backed locking primitive.
+- Gateway JWT generation lock recovery: invalid state is a crashed NemoClaw process leaving `.jwt-generating` behind after taking the exclusive host-side bundle-generation lock. The source boundary is NemoClaw's own atomic JWT bundle writer; OpenShell consumes the resulting paths but does not own this lock, so the source fix belongs here. Live contenders wait up to five seconds for the owner to publish its bundle, after which they fail closed. A stale lock is removed only when it contains a numeric owner PID that the operating system reports as absent, and a per-acquisition nonce prevents a replaced lock from being mistaken for the observed owner. Malformed or unprobeable locks continue to fail closed. Regression coverage lives in `src/lib/onboard/docker-driver-gateway-jwt-bundle.test.ts`, including a synchronized 12-process contention test. Remove the lock and its recovery together if JWT bundle generation moves into OpenShell or to an OS-backed locking primitive.
 - Markerless sandbox gateway recovery output: invalid state is newer OpenShell sandbox exec/relaunch output that starts the gateway launcher but omits NemoClaw's legacy `GATEWAY_PID=` or `ALREADY_RUNNING` markers. Source boundary is OpenShell exec/recovery output format; NemoClaw treats the text as "may have started" only and still requires a healthy gateway probe. Regression coverage lives in `test/cli/connect-recovery-markerless.test.ts`. Remove the markerless heuristic when OpenShell provides a stable machine-readable recovery marker.
 - Sessions admin gateway RPC helper: invalid state is a host CLI session reset/delete action that needs OpenClaw backend/operator scope while preserving gateway token, loopback, and auto-pair boundaries. Source boundary is OpenClaw's gateway-runtime API; NemoClaw's helper is limited to `sessions.reset` and `sessions.delete`. Regression coverage lives in `src/lib/actions/sandbox/sessions/gateway-rpc-call.test.ts`. Add new methods only with a caller, allowlist entry, and negative test.

 Use `NEMOCLAW_GATEWAY_BIND_ADDRESS=0.0.0.0` only on supported gateway modes and only when other hosts on the network should be able to reach the gateway.
 
+### Older-glibc gateway compatibility container
+
+OpenShell 0.0.71 directly supports Linux hosts with glibc 2.28 or newer. On an older trusted host, `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1` explicitly opts into NemoClaw's compatibility container. Leave it unset on supported hosts.
+
+The compatibility container uses host networking and mounts the host Docker socket read-only. A read-only socket mount still permits privileged Docker API operations and can control the host, so do not enable this mode on an untrusted or shared host. The gateway remains loopback-bound, and startup fails closed unless the configured Unix socket answers as a Docker daemon. See the [OpenShell 0.0.71 gateway auth review](../security/openshell-0.0.71-gateway-auth-review#source-of-truth-boundaries) for the accepted boundary and removal conditions.

-Unauthenticated MCP servers can omit `--env`.
+V1 requires exactly one `--env` bearer credential per server. Remote endpoints
+must use HTTPS; plain HTTP is accepted only for OpenShell host aliases. URLs
+with query strings are rejected because the URL is persisted and displayed.
+Use a distinct environment variable name for each managed MCP server in the same sandbox;
+OpenShell static credential keys are sandbox-wide and cannot be attached twice.
+Endpoint paths must be literal and canonical: percent escapes, backslashes,
+semicolons, OpenShell glob metacharacters, and explicit port zero are rejected.
+
+## Authenticated MCP Security Boundary
+
+Authenticated MCP is the intended configuration. The agent stores only the
+`openshell:resolve:env:KEY` placeholder. OpenShell keeps the raw credential in
+its provider store and combines credential replacement with the generated MCP
+policy at egress.
+
+For each request, OpenShell first evaluates the effective network policy for
+the host, port, runtime identity, literal endpoint path, and MCP method. The
+generated MCP policy grants only the configured target and explicit MCP
+profile. Only a request that passes policy reaches OpenShell's credential
+replacement stage, where OpenShell replaces the authorization placeholder
+immediately before writing the request upstream. An endpoint, path, binary, or
+method not granted by an attached policy is denied without being rewritten or
+sent to the server.
+
+OpenShell's current static placeholder lookup is sandbox-wide; the credential
+key itself is not endpoint-bound. The generated MCP policy narrows this managed
+route, but current OpenShell policy cannot declare which attached placeholder
+key may be resolved at that endpoint. Code running as an allowed adapter binary
+can therefore present another sandbox-attached static placeholder to the
+configured MCP endpoint, and any other effective policy that permits that
+binary can likewise send the MCP placeholder elsewhere. Treat the configured
+MCP service as trusted with every static credential attached to that sandbox,
+or isolate it in a dedicated sandbox. Use dedicated, least-privilege tokens and
+unique environment keys, avoid broad egress grants for adapter binaries, and
+audit the sandbox's complete effective policy. NemoClaw rejects credential-key
+reuse between its managed MCP servers to reduce accidental overlap, but that
+does not add endpoint-level credential scoping to OpenShell.
+
+Use an MCP service you trust with the credential it receives. MCP response
+bodies and SSE streams return through OpenShell's existing sandbox egress path;
+as with any authenticated API, a server that possesses a credential can
+deliberately return that value in its response. This does not expose the raw
+credential to the sandbox before the request is authorized and sent to that
+server.

-Hermes config changes and gateway reloads stay inside the sandbox. Rootless
-OpenShell drivers update and signal the sandbox-owned Hermes process directly.
-The root-started Docker fallback uses a root-owned Unix socket inside that same
-sandbox to validate and serialize config/hash updates before signaling Hermes.
-This lifecycle socket carries no MCP traffic and no service credential, and
-there is no host-side MCP process.
+Hermes config changes and gateway reloads stay inside the sandbox. NemoClaw
+invokes the validated transaction helper as a one-shot `openshell sandbox exec`
+command. OpenShell current main places that command in the same workload uid
+and network namespace as Hermes, so the helper can update the same-uid
+compatibility hash, signal the exact gateway PID, and verify its loopback health.
+The helper rejects non-root execution when the root-separated lifecycle marker
+or a separately owned gateway is present, and validates the PID against the
+trusted Hermes gateway launcher before signaling it. There is no persistent
+control socket or service. The command carries no MCP traffic or raw service
+credential; its payload contains only the endpoint definition and OpenShell
+placeholder.

 `openshell:resolve:env:KEY` into the sandbox-side MCP config, and relies on
 OpenShell to resolve the placeholder at egress.
 
+Do not reuse OpenShell's Google Cloud compatibility names as MCP bearer keys.
+NemoClaw rejects `GCP_PROJECT_ID`, `GOOGLE_CLOUD_PROJECT`, `CLOUD_ML_REGION`,
+`GCP_LOCATION`, `GCP_SERVICE_ACCOUNT_EMAIL`, `GOOSE_PROVIDER`,
+`ANTHROPIC_VERTEX_PROJECT_ID`, and `VERTEX_LOCATION` because OpenShell exposes
+those non-secret configuration names as child-process values. It also rejects
+`GCE_METADATA_HOST`, which OpenShell rewrites for its metadata emulator. Choose
+a dedicated name such as `MY_SERVICE_MCP_TOKEN`.
+
 V1 requires exactly one `--env` bearer credential per server. Remote endpoints
 must use HTTPS; plain HTTP is accepted only for OpenShell host aliases. URLs
 with query strings are rejected because the URL is persisted and displayed.

 The sandbox agent connects directly to the configured endpoint, and OpenShell enforces policy and replaces credentials in its existing sandbox egress path.
 No NemoClaw host process remains running after an `mcp` lifecycle command returns.
 
+## Architecture Decision
+
+This native OpenShell design supersedes the original host-side stdio-to-HTTP proxy proposed in NVIDIA/NemoClaw#566.
+NemoClaw does not accept an inline secret-and-command tuple, persist a raw MCP service credential, or operate a host-side MCP data-plane process.
+The only supported managed path is authenticated Streamable HTTP through an OpenShell `protocol: mcp` policy, with the raw credential held by the OpenShell provider and replaced only on an authorized outbound request.
+Host-side MCP data-plane bridges, proxies, relays, listeners, and stdio translation are explicitly out of scope for this feature.

 Hermes config changes and gateway reloads stay inside the sandbox.
-NemoClaw invokes the validated transaction helper as a one-shot `openshell sandbox exec` command.
-The required OpenShell build places that command in the same workload uid and network namespace as Hermes, so the helper can update the same-uid compatibility hash, signal the exact gateway PID, and verify its loopback health.
-The helper rejects non-root execution when the root-separated lifecycle marker or a separately owned gateway is present.
-It validates the PID against the trusted Hermes gateway launcher before signaling it.
-There is no persistent control socket or service.
+NemoClaw invokes the validated transaction helper as a one-shot, policy-authorized `openshell sandbox exec --lifecycle` command.
+The Hermes process policy grants a closed operation ID that OpenShell maps to the NemoClaw image's exact root-owned helper path and fixed argument shape; OpenShell reauthorizes the request in the gateway and supervisor, validates the helper and its interpreter chain, and runs it directly through the existing authenticated gateway-to-supervisor control stream.
+Root ownership and non-writability enforce immutability against the running workload; they do not establish image provenance, code signing, or semantic trust.
+The operation keeps the normal workload uid, gid, supplementary groups, Landlock policy, seccomp policy, and empty credential environment.
+The supported helper entrypoint additionally consumes a one-shot inherited Unix descriptor with a root supervisor peer and the exact lifecycle handshake; ordinary sandbox exec does not receive that descriptor or select the private control target.
+This descriptor authenticates the packaged helper's supported invocation route; it is an orchestration check, not an additional privilege boundary against code already running as the workload identity.
+Lifecycle mode grants no additional uid, gid, groups, Linux capabilities, provider credentials, filesystem or network access, or persistent privileged channel, and OpenShell keeps provider values and policy mutation outside the sandbox.
+The helper updates the managed compatibility hash, validates the PID against the trusted Hermes gateway launcher before signaling it, and verifies loopback health after reload.
+There is no host listener, shell, persistent control socket, or service for this operation.
 The command carries no MCP traffic or raw service credential, and its payload contains only the endpoint definition and OpenShell placeholder.

+# OpenClaw MCP Runtime Dependency Review
+
+This file records the reviewed `mcporter` baseline installed in the OpenClaw sandbox image.
+Update it whenever `MCPORTER_VERSION` or its integrity value changes in `Dockerfile.base` or `Dockerfile`.
+
+- Package: `mcporter@0.7.3`
+- Purpose: in-sandbox OpenClaw MCP configuration and client adapter; it is not a host bridge, proxy, relay, or listener.
+- Registry source: `https://registry.npmjs.org/mcporter/-/mcporter-0.7.3.tgz`
+- Repository: `https://github.com/steipete/mcporter`
+- License: `MIT`, from the npm registry package metadata.
+- npm integrity: `sha512-egoPVYqTnWb3NjRIxo+xc8OrAI0dlPrJm9pAiZx0pImuNIV5rKhGtTnIfH/Y1ldGPVu74ibj3KR5c9U/QSdQFA==`
+- Registry metadata reviewed: 2026-06-27.
+- Advisory command: `npm install --package-lock-only --ignore-scripts mcporter@0.7.3 && npm audit --omit=dev`
+- Advisory review date: 2026-06-27.
+- Advisory result: `0` known vulnerabilities across the resolved production dependency graph.
+
+The image install uses `--ignore-scripts` because the published package declares no install-time lifecycle script and NemoClaw needs only its already-built CLI.
+Disabling scripts also prevents transitive packages from executing lifecycle code during the trusted image build.
+The exact version and registry integrity check remain mandatory; this review does not replace either control.

 ## Architecture Decision
 
+**Status:** Accepted on June 27, 2026, as the normative design for the next NemoClaw release and the implementation that supersedes the original acceptance text in NVIDIA/NemoClaw#566.
+
 This native OpenShell design supersedes the original host-side stdio-to-HTTP proxy proposed in NVIDIA/NemoClaw#566.
 NemoClaw does not accept an inline secret-and-command tuple, persist a raw MCP service credential, or operate a host-side MCP data-plane process.
 The only supported managed path is authenticated Streamable HTTP through an OpenShell `protocol: mcp` policy, with the raw credential held by the OpenShell provider and replaced only on an authorized outbound request.
 Host-side MCP data-plane bridges, proxies, relays, listeners, and stdio translation are explicitly out of scope for this feature.
+The original issue's Claude-style `-e KEY=VALUE -- <command>`, plaintext `http://host.docker.internal:<port>`, stored environment value, and `127.0.0.1` proxy clauses are rejected by this decision rather than deferred implementation work.

 If NemoClaw reports that MCP policy capability is unavailable, install the required OpenShell build and rerun onboarding.
 NemoClaw checks the installed OpenShell binary for the `protocol: mcp` capability and does not enable managed MCP from a version number alone.
 
+If a Hermes sandbox is alive but its gateway is not running after a supervisor or container restart, run `$$nemoclaw <sandbox> recover` before retrying the MCP command.
+Recovery re-establishes the managed Hermes service lifecycle, API forwarding, and the exit-75 reload loop used for transactional MCP configuration changes.

 The `env.missing` field reports whether the original host variable is currently exported.
 An existing valid provider can remain ready when that host variable is unset because OpenShell retains the credential.

+Hermes currently has no managed MCP mutation API, so direct config edits would
+otherwise expose a partial-write/reload race. The upstream Hermes boundary

+checks, and reload acknowledgement instead. hermes-mcp-config-transaction.test.ts

 If NemoClaw reports that MCP policy capability is unavailable, install the required OpenShell build and rerun onboarding.
-NemoClaw checks the installed OpenShell binary for the `protocol: mcp` capability and does not enable managed MCP from a version number alone.
+NemoClaw checks inspectable installed OpenShell artifacts for the `protocol: mcp` capability and does not enable managed MCP from a version number alone.
+For image-backed or compressed supervisors without an inspectable host runtime artifact, that onboarding check is provisional.
+Before any credential or provider side effect, the MCP command loads the exact generated policy with `policy set --wait` and exact-matches the effective state; a runtime that rejects `protocol: mcp` therefore fails closed.
 
 If a Hermes sandbox is alive but its gateway is not running after a supervisor or container restart, run `$$nemoclaw <sandbox> recover` before retrying the MCP command.
 Recovery re-establishes the managed Hermes service lifecycle, API forwarding, and the exit-75 reload loop used for transactional MCP configuration changes.

Only Docker Engine, Docker Desktop, and Colima are supported. See issue #420 (closed). |
 | Intel Mac (macOS x86_64) | Unsupported | OpenShell does not publish macOS x86_64 standalone gateway assets. Install hard-fails on x86_64 macOS (`scripts/install-openshell.sh:411`). See issue #954 (closed). |
 | Non-Ubuntu/Debian Linux distros | Unsupported | Installer assumes `apt-get`. Fedora/Rocky/Alma/Arch/NixOS are not validated and the installer's package-manager probes do not cover them. See open issue #899 (Fedora hang). |
 | Native Kubernetes or OpenShift deployments | Unsupported | NemoClaw runs the sandbox as a Docker container, not a Kubernetes pod. The default Docker-driver topology does not embed k3s. Operator-managed K8s/OpenShift deployments are out of scope; see issue #407 (community OpenShift through agent-sandbox CRD). |
 | Air-gapped / offline installs | Unsupported | Onboard assumes network reachability for package fetches, container pulls, and provider validation. See open issues #4872 and #2218 (production-deployment epic covering air-gapped support, China network guidance, multi-host topology). |
 | Windows-on-ARM GPU passthrough | Unsupported | Windows-on-ARM CPU paths run under WSL2 'tested with limitations', but GPU passthrough on WOA is denylisted (`src/lib/onboard/wsl-docker-desktop-gpu.ts:188`, `src/lib/inference/gpu-trust.test.ts:70`). See closed issue #4565. |
-| Non-NVIDIA GPUs (AMD/ROCm, Intel Arc, Apple Metal) | Unsupported | Local vLLM and NIM paths assert NVIDIA CDI presence with `assertCdiNvidiaGpuSpecPresent` (`src/lib/onboard.ts:1633`). NemoClaw does not install non-NVIDIA accelerator drivers. |

 | Other LangChain, AutoGen, CrewAI, or non-listed agent harnesses | Unsupported | LangChain Deep Agents Code is the only integrated LangChain-family harness (see the Agents section above; status `Experimental`). Other LangChain harnesses, AutoGen, CrewAI, and any agent runtime not listed in the Agents table are not integrated. Bringing more harnesses is tracked as a research epic (see open issue #4861) but is not on the current roadmap. |
 | Multi-user host sharing | Unsupported | Sandboxes are scoped to a single host user. NemoClaw treats multi-user hosts as a risk and warns at onboard; see `docs/security/openclaw-controls.mdx` Multi-user detection. |
 | Hosted SaaS / managed NemoClaw | Unsupported | There is no managed offering. Supported deployment paths are Local CLI onboard, Remote GPU with Brev CLI, and Brev web UI. |

 | Item | Status | Why |
 |------|--------|-----|
-| Podman / other container runtimes | Unsupported | Onboard surfaces an explicit unsupported-runtime error for Podman (`src/lib/onboard.ts:1659` prints the rejection; `src/lib/onboard/preflight.ts:622` flags the unsupported runtime upstream). Only Docker Engine, Docker Desktop, and Colima are supported. See issue #420 (closed). |

Only Docker Engine, Docker Desktop, and Colima are supported. See issue #420 (closed). |
+| Intel Mac (macOS x86_64) | Unsupported | OpenShell does not publish macOS x86_64 standalone gateway assets. Install hard-fails on x86_64 macOS (`scripts/install-openshell.sh:555`). See issue #954 (closed). |
 | Non-Ubuntu/Debian Linux distros | Unsupported | Installer assumes `apt-get`. Fedora/Rocky/Alma/Arch/NixOS are not validated and the installer's package-manager probes do not cover them. See open issue #899 (Fedora hang). |
 | Native Kubernetes or OpenShift deployments | Unsupported | NemoClaw runs the sandbox as a Docker container, not a Kubernetes pod. The default Docker-driver topology does not embed k3s. Operator-managed K8s/OpenShift deployments are out of scope; see issue #407 (community OpenShift through agent-sandbox CRD). |
 | Air-gapped / offline installs | Unsupported | Onboard assumes network reachability for package fetches, container pulls, and provider validation. See open issues #4872 and #2218 (production-deployment epic covering air-gapped support, China network guidance, multi-host topology). |
 | Windows-on-ARM GPU passthrough | Unsupported | Windows-on-ARM CPU paths run under WSL2 'tested with limitations', but GPU passthrough on WOA is denylisted (`src/lib/onboard/wsl-docker-desktop-gpu.ts:188`, `src/lib/inference/gpu-trust.test.ts:70`). See closed issue #4565. |
-| Non-NVIDIA GPUs (AMD/ROCm, Intel Arc, Apple Metal) | Unsupported | Local vLLM and NIM paths assert NVIDIA CDI presence with `assertCdiNvidiaGpuSpecPresent` (`src/lib/onboard.ts:1685`). NemoClaw does not install non-NVIDIA accelerator drivers. |
+| Non-NVIDIA GPUs (AMD/ROCm, Intel Arc, Apple Metal) | Unsupported | Local vLLM and NIM paths assert NVIDIA CDI presence with `assertCdiNvidiaGpuSpecPresent` (`src/lib/onboard/fatal-runtime-preflight.ts:78`). NemoClaw does not install non-NVIDIA accelerator drivers. |
 | Other LangChain, AutoGen, CrewAI, or non-listed agent harnesses | Unsupported | LangChain Deep Agents Code is the only integrated LangChain-family harness (see the Agents section above; status `Experimental`). Other LangChain harnesses, AutoGen, CrewAI, and any agent runtime not listed in the Agents table are not integrated. Bringing more harnesses is tracked as a research epic (see open issue #4861) but is not on the current roadmap. |
 | Multi-user host sharing | Unsupported | Sandboxes are scoped to a single host user. NemoClaw treats multi-user hosts as a risk and warns at onboard; see `docs/security/openclaw-controls.mdx` Multi-user detection. |
 | Hosted SaaS / managed NemoClaw | Unsupported | There is no managed offering. Supported deployment paths are Local CLI onboard, Remote GPU with Brev CLI, and Brev web UI. |

+NemoClaw resolves public hostnames before registration, rejects private, local, and special-use targets, and pins the resolved addresses in the generated policy. OpenShell re-resolves the hostname for each new connection, requires every current answer to match those pinned `allowed_ips`, and connects to the same validated socket addresses. A DNS change to a private, special-use, or otherwise unpinned address therefore fails closed instead of widening the route.
 `restart` resolves the hostname again before updating that policy.
 An OpenShell host alias can identify a native MCP service you already run, but NemoClaw does not start or wrap that service.
 That service must present a certificate valid for the alias, signed by a CA already trusted by the sandbox supervisor; installing a new CA requires restarting the supervisor before registration.

-OpenShell current main attaches static provider credentials at sandbox scope; it does not reserve a credential key exclusively for one endpoint, expose an immutable provider binding on an attachment, provide a `tls: require` policy mode, bind the HTTP `Host` header to the policy destination, or include query parameters in MCP path matching.

 Consequently, the generated policy narrows the managed MCP client path but cannot prevent a separate broader inspected-HTTP policy in the same sandbox from resolving an attached placeholder.
 NemoClaw rejects credential-key reuse between its managed MCP servers and requires a dedicated provider for each definition, but operators must also avoid granting broader routes to the same adapter runtime.

 If deletion is refused, NemoClaw restores the previous MCP state.
 Provider deletion and registry cleanup happen only after OpenShell confirms that the sandbox is gone.
 NemoClaw prechecks the recorded provider ID and credential-key shape before mutation and uses a random per-add provider-name suffix to avoid accidental name reuse.
-OpenShell current main still performs update, attach, detach, and delete by mutable provider name, so those checks are not an atomic identity binding; do not concurrently replace or mutate a managed provider through another OpenShell client while an MCP lifecycle command is running.

Subject: [PATCH 205/384] fix(rebuild): restore all channel presets on
 start+rebuild after stop (#5596)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After stop+rebuild, channel presets are correctly pruned so disabled
channels lose their egress policy. But applyPreset() only updates
sb.policies for presets it actually applies — so after stop+rebuild,
sb.policies no longer contains any channel preset. On the subsequent
start+rebuild, backupSandboxStateForRebuild reads this reduced
sb.policies, savedPresets contains no channel presets, and step 5.5
silently skips them. Only presets with requiredAtCreate=true (currently
slack only) survive via the onboard recreation path.

Fix: in step 5.5, merge in allMessagingChannelPolicyPresets for
currently-enabled channels so they are applied regardless of whether
they survived in sb.policies. This recovers telegram, discord, whatsapp,
and wechat presets after a stop+rebuild → start+rebuild cycle.

+- Policy mutations now read the round-trippable base policy instead of the
+  effective policy, preventing provider-composed `_provider_*` entries from
+  being sent back through `policy set` while preserving existing MCP rules.

+# OpenShell 0.0.72 Compatibility Review
+
+Review date: 2026-06-29
+
+Scope: NemoClaw's stable OpenShell `0.0.72` pin, Docker-driver gateway auth,
+policy mutation, and MCP/JSON-RPC policy compatibility.
+
+## Release identity
+
+- Stable tag: `NVIDIA/OpenShell@v0.0.72`
+  (`8cb16de9eae4c44d7d31e1493747d8c10abb5963`).
+- The upstream release workflow completed all 54 jobs, including the MCP
+  conformance lane, package smoke tests, release publication, and GHCR tags.
+- NemoClaw pins the published CLI, gateway, and sandbox SHA-256 digests and the
+  multi-architecture `ghcr.io/nvidia/openshell/supervisor:0.0.72` image.
+
+## Source-of-truth boundaries
+
+The generated gateway auth contract remains the one reviewed in
+[OpenShell 0.0.71 Gateway Auth Review](./openshell-0.0.71-gateway-auth-review).
+The `v0.0.71...v0.0.72` source comparison does not change the gateway config
+loader, local TLS tables, mTLS user authentication, gateway JWT issuer, or
+`SandboxJwtAuthenticator` contract used by NemoClaw. The live
+`openshell-gateway-auth-source-contract.test.ts` scenario revalidates that
+NemoClaw keeps the main OpenShell listener on `127.0.0.1`, rejects unauthenticated Docker
+origin calls, accepts a correctly scoped sandbox JWT over guest mTLS, rejects
+cross-sandbox tokens, and scrubs `OPENSHELL_DISABLE_GATEWAY_AUTH=true`.
+The inherited contract also continues to reject
+`NEMOCLAW_GATEWAY_BIND_ADDRESS=0.0.0.0`; user principals are rejected from sandbox-only methods.
+
+The compatibility container remains an explicit trusted-host fallback behind
+`NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1`. It uses host networking and
+read-only Docker socket access, so directly supported glibc 2.28+ hosts remain
+preferred. Wildcard gateway binds remain rejected while gateway JWT auth is
+active.
+
+## Round-trippable policy boundary
+
+OpenShell `0.0.72` reserves the `_provider_*` network-policy namespace for
+provider composition. `openshell policy get <sandbox> --full` now returns the
+effective policy including those derived entries, while `policy set` rejects
+user-authored reserved keys. The exact invalid state is a NemoClaw read-modify-
+write path feeding provider-composed `_provider_*` entries back into
+`openshell policy set`.
+
+Every NemoClaw policy read-modify-write path, including preset merges and
+blueprint additions, plus every Shields snapshot-for-restore path therefore
+starts from:
+
+```bash
+openshell policy get --base <sandbox>
+```
+
+Read-only status and diagnostic views continue to use `--full`. Regression
+coverage verifies the mutation commands select `--base`, provider-composed
+entries never reach `policy set`, and existing MCP policy fields survive a
+preset or blueprint merge.
+
+## MCP and JSON-RPC policy support
+
+OpenShell `0.0.72` adds `protocol: mcp` for MCP Streamable HTTP and
+`protocol: json-rpc` for generic JSON-RPC-over-HTTP enforcement. MCP rules can
+match methods and `tools/call` tool names, support allow and deny rules, and
+fail closed for malformed or ambiguous request frames. The upstream MCP
+conformance lane passed `initialize`, `tools_call`, and
+`elicitation-sep1034-client-defaults` with no expected failures.
+
+This dependency PR preserves the new MCP and JSON-RPC YAML fields when
+NemoClaw merges existing policies. It does not widen NemoClaw's strict
+blueprint-addition schema to author new MCP endpoints; that is a separate
+product/API change. OpenShell's enforcement covers sandbox-to-server
+Streamable HTTP requests, not stdio MCP or generic inbound traffic.
+
+## Local contract coverage
+
+- Installer and runner tests pin all eight published release digests.
+- The sticky-version guard replaces a too-new `0.0.73` install with `0.0.72`.
+- Policy tests cover `--base` command construction and MCP/JSON-RPC field preservation.
+- Blueprint tests prove the merged policy excludes reserved provider entries.
+- The live gateway auth and gateway-upgrade scenarios run against `0.0.72`.

 round-trip boundary:
 
 - Stable installs pin OpenShell `0.0.72` release artifacts and supervisor image,
-  including the upstream MCP and JSON-RPC policy-enforcement implementation.
+  adding MCP Streamable HTTP and JSON-RPC request-policy enforcement.
 - Policy mutations now read the round-trippable base policy instead of the
   effective policy, preventing provider-composed `_provider_*` entries from
   being sent back through `policy set` while preserving existing MCP rules.

+
+This review covers NemoClaw's stable OpenShell `0.0.72` pin, Docker-driver gateway authentication, policy mutation, and MCP and JSON-RPC policy compatibility.
+The review was completed on June 29, 2026.
+
+## Release Identity
+
+- The stable tag is `NVIDIA/OpenShell@v0.0.72` at commit `8cb16de9eae4c44d7d31e1493747d8c10abb5963`.
+- The upstream release workflow completed all 54 jobs, including the MCP conformance lane, package smoke tests, release publication, and GHCR tags.
+- NemoClaw pins the published CLI, gateway, and sandbox SHA-256 digests and the multi-architecture `ghcr.io/nvidia/openshell/supervisor:0.0.72` image.
+
+## Source-of-Truth Boundaries
+
+The generated gateway authentication contract remains unchanged from the OpenShell `0.0.71` dependency review.
+The `v0.0.71...v0.0.72` source comparison does not change the gateway config loader, local TLS tables, mTLS user authentication, gateway JWT issuer, or `SandboxJwtAuthenticator` contract used by NemoClaw.
+The live `openshell-gateway-auth-source-contract.test.ts` scenario revalidates that NemoClaw keeps the main OpenShell listener on `127.0.0.1`, rejects unauthenticated Docker-origin calls, accepts a correctly scoped sandbox JWT over guest mTLS, rejects cross-sandbox tokens, and scrubs `OPENSHELL_DISABLE_GATEWAY_AUTH=true`.
+The inherited contract also continues to reject `NEMOCLAW_GATEWAY_BIND_ADDRESS=0.0.0.0`.
+User principals remain blocked from sandbox-only methods.
+
+The compatibility container remains an explicit trusted-host fallback behind `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1`.
+It uses host networking and read-only Docker socket access, so directly supported glibc 2.28 or newer hosts remain preferred.
+Wildcard gateway binds remain rejected while gateway JWT authentication is active.
+
+## Round-Trippable Policy Boundary
+
+OpenShell `0.0.72` reserves the `_provider_*` network-policy namespace for provider composition.
+`openshell policy get <sandbox> --full` returns the effective policy including those derived entries, while `policy set` rejects user-authored reserved keys.
+The invalid state occurs when a NemoClaw read-modify-write path feeds provider-composed `_provider_*` entries back into `openshell policy set`.
+
+Every NemoClaw policy read-modify-write path, including preset merges and blueprint additions, and every Shields snapshot-for-restore path therefore starts from:
+
+```bash
+openshell policy get --base <sandbox>
+```
+
+Read-only status and diagnostic views continue to use `--full`.
+Regression coverage verifies that mutation commands select `--base`, provider-composed entries never reach `policy set`, and existing MCP policy fields survive a preset or blueprint merge.
+
+## MCP and JSON-RPC Policy Support
+
+OpenShell `0.0.72` adds `protocol: mcp` for MCP Streamable HTTP and `protocol: json-rpc` for generic JSON-RPC-over-HTTP enforcement.
+MCP rules can match methods and `tools/call` tool names, support allow and deny rules, and fail closed for malformed or ambiguous request frames.
+The upstream MCP conformance lane passed `initialize`, `tools_call`, and `elicitation-sep1034-client-defaults` with no expected failures.
+
+This dependency PR preserves the new MCP and JSON-RPC YAML fields when NemoClaw merges existing policies.
+It does not widen NemoClaw's strict blueprint-addition schema to author new MCP endpoints because that is a separate product and API change.
+OpenShell enforcement covers sandbox-to-server Streamable HTTP requests, not stdio MCP or generic inbound traffic.
+
+## Local Contract Coverage
+
+- Installer and runner tests pin all eight published release digests.
+- The sticky-version guard replaces a too-new `0.0.73` install with `0.0.72`.
+- Policy tests cover `--base` command construction and MCP and JSON-RPC field preservation.
+- Blueprint tests prove the merged policy excludes reserved provider entries.
+- The live gateway authentication and gateway-upgrade scenarios run against `0.0.72`.

-# Brev launchable startup script — CI-Ready CPU
-#
-# Pre-bakes a VM with everything needed for NemoClaw E2E tests so that
-# CI runs only need to: rsync branch code → npm ci → nemoclaw onboard → test.
-#
-# What this installs:
-#   1. Docker (docker.io) — enabled and running
-#   2. Node.js 22 (nodesource)
-#   3. OpenShell CLI binary (pinned release)
-#   4. NemoClaw repo cloned with npm deps installed and TS plugin built
-#   5. Docker images pre-pulled (sandbox-base, openshell/supervisor, node:22-trixie-slim)
-#
-# What this does NOT install (intentionally):
-#   - code-server (not needed for automated CI)
-#   - VS Code themes/extensions
-#   - NVIDIA Container Toolkit (see brev-launchable-ci-gpu.sh for GPU flavor)
-#   - Ollama / vLLM
-#
-# Readiness detection:
-#   Writes /var/run/nemoclaw-launchable-ready when complete.
-#   Also writes "=== Ready ===" to /tmp/launch-plugin.log for backward compat.
-#
-# Usage (Brev launchable startup script — one-liner that curls this):
+# Brev CI-ready CPU launchable: installs Docker, Node.js 22, OpenShell, and
+# NemoClaw, then pre-pulls the images needed by E2E tests.
+# Usage:
 #   curl -fsSL https://raw.githubusercontent.com/NVIDIA/NemoClaw/<ref>/scripts/brev-launchable-ci-cpu.sh | bash
 #   bash scripts/brev-launchable-ci-cpu.sh --print-openshell-version  # resolve only

+- The stable Docker-driver default pins the multi-architecture supervisor manifest as `ghcr.io/nvidia/openshell/supervisor@sha256:80ed9cda5bf672fefdb9dcd4604b40a8b09c0891b6eb9d03e10227c7e3dfb49d`. Explicit operator overrides and the opt-in development channel remain separate trust decisions.

+The generated gateway authentication contract remains unchanged from the [OpenShell 0.0.71 gateway authentication review](./openshell-0.0.71-gateway-auth-review).
 The `v0.0.71...v0.0.72` source comparison does not change the gateway config loader, local TLS tables, mTLS user authentication, gateway JWT issuer, or `SandboxJwtAuthenticator` contract used by NemoClaw.
 The live `openshell-gateway-auth-source-contract.test.ts` scenario revalidates that NemoClaw keeps the main OpenShell listener on `127.0.0.1`, rejects unauthenticated Docker-origin calls, accepts a correctly scoped sandbox JWT over guest mTLS, rejects cross-sandbox tokens, and scrubs `OPENSHELL_DISABLE_GATEWAY_AUTH=true`.
 The inherited contract also continues to reject `NEMOCLAW_GATEWAY_BIND_ADDRESS=0.0.0.0`.

 It uses host networking and read-only Docker socket access, so directly supported glibc 2.28 or newer hosts remain preferred.
 Wildcard gateway binds remain rejected while gateway JWT authentication is active.
 
+The release source boundary is the immutable upstream tag, its GitHub release asset digests, and the GHCR manifest digest produced by the linked release workflow.
+A mutable tag, a digest copied from another release, or a checksum file that disagrees with NemoClaw's table is an invalid state.
+NemoClaw cannot make an upstream release mutable source trustworthy after publication, so the installer independently pins every consumed archive and the stable runtime uses the immutable supervisor manifest.
+`install-openshell-version-check.test.ts` compares all eight archive mappings with the checked-in installer table, and `docker-driver-gateway-runtime.test.ts` locks the stable supervisor default while preserving an explicit operator override.
+These version-specific pins are removed only when NemoClaw drops `0.0.72` support or replaces them with independently verified artifacts for a newly supported release.

 ## Round-Trippable Policy Boundary
 
 OpenShell `0.0.72` reserves the `_provider_*` network-policy namespace for provider composition.

 NemoClaw resolves public hostnames before registration, rejects private, local, and special-use targets, and pins the resolved addresses in the generated policy. OpenShell re-resolves the hostname for each new connection, requires every current answer to match those pinned `allowed_ips`, and connects to the same validated socket addresses. A DNS change to a private, special-use, or otherwise unpinned address therefore fails closed instead of widening the route.
 `restart` resolves the hostname again before updating that policy.
 An OpenShell host alias can identify a native MCP service you already run, but NemoClaw does not start or wrap that service.
+For that exact alias, NemoClaw omits `allowed_ips` and relies on OpenShell `v0.0.72`'s trusted, driver-specific gateway-address path instead of granting private-network CIDRs.
 That service must present a certificate valid for the alias, signed by a CA already trusted by the sandbox supervisor; installing a new CA requires restarting the supervisor before registration.

+Both image paths install the committed graph with `npm ci --ignore-scripts --omit=dev` because the published package declares no install-time lifecycle script and NemoClaw needs only its already-built CLI.
 Disabling scripts also prevents transitive packages from executing lifecycle code during the trusted image build.
-The exact version and registry integrity check remain mandatory; this review does not replace either control.
+The lock records the exact version, registry URL, and integrity for every transitive package; the top-level registry integrity check remains an independent control.

 The compatibility container remains an explicit trusted-host fallback behind `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1`.
 It uses host networking and read-only Docker socket access, so directly supported glibc 2.28 or newer hosts remain preferred.
 Wildcard gateway binds remain rejected while gateway JWT authentication is active.
+Review this fallback at every stable OpenShell bump and remove it in the same NemoClaw release that raises every supported Linux host to OpenShell's native glibc floor and passes the exact-head gateway-authentication and gateway-upgrade matrix without the flag.
 
 The release source boundary is the immutable upstream tag, its GitHub release asset digests, and the GHCR manifest digest produced by the linked release workflow.
 A mutable tag, a digest copied from another release, or a checksum file that disagrees with NemoClaw's table is an invalid state.

 NemoClaw accepts only canonical HTTPS MCP URLs and writes the credential placeholder only into the `Authorization` header.
 
-OpenShell v0.0.72 and current main attach static provider credentials at sandbox scope; they do not reserve a credential key exclusively for one endpoint, expose an immutable provider binding on an attachment, provide a `tls: require` policy mode, bind the HTTP `Host` header to the policy destination, or include query parameters in MCP path matching.
-Consequently, the generated policy narrows the managed MCP client path but cannot prevent a separate broader inspected-HTTP policy in the same sandbox from resolving an attached placeholder.
-NemoClaw rejects credential-key reuse between its managed MCP servers and requires a dedicated provider for each definition, but operators must also avoid granting broader routes to the same adapter runtime.

+OpenShell v0.0.72 attributes network policy with `/proc/<pid>/exe` and process ancestors, so the script-based adapters require Node or Python interpreter grants rather than immutable package-entrypoint identities.

+## DNS Pinning Source and Runtime Contract
+
+The MCP integration pins the OpenShell DNS enforcement contract to `NVIDIA/OpenShell@8cb16de9eae4c44d7d31e1493747d8c10abb5963`.
+In that implementation, `crates/openshell-supervisor-network/src/proxy.rs:2476-2502` produces one socket-address list, `crates/openshell-supervisor-network/src/proxy.rs:2527-2567` validates every address in that list, and `crates/openshell-supervisor-network/src/proxy.rs:2622-2630` returns the validated list unchanged.
+The CONNECT path passes that returned list directly to `TcpStream::connect` at `crates/openshell-supervisor-network/src/proxy.rs:822-832`.
+The explicit HTTP-forward path carries the same returned list from `crates/openshell-supervisor-network/src/proxy.rs:3885-3893` to `crates/openshell-supervisor-network/src/proxy.rs:4123-4125`.
+There is no second hostname resolution between validation and connection in either path.
+
+The live MCP scenario registers a hostname while it resolves to a pinned public address, remaps it to a reachable unpinned runner address, and sends an MCP `tools/list` request beneath each adapter runtime identity.
+OpenClaw uses the managed Node identity, Hermes uses its managed Python identity, and LangChain Deep Agents Code uses its managed virtual-environment Python identity.
+The scenario requires an OpenShell HTTP 403 or CONNECT 403 for every adapter and verifies that the upstream MCP server recorded zero requests.

 ## Architecture Decision
 
-**Status:** Accepted on June 27, 2026, as the normative design for the next NemoClaw release and the implementation that supersedes the original acceptance text in NVIDIA/NemoClaw#566.
+**Status:** [Accepted on June 30, 2026](https://github.com/NVIDIA/NemoClaw/issues/566#issuecomment-4847534784) as the normative design for the next NemoClaw release and the implementation that supersedes the original acceptance text in NVIDIA/NemoClaw#566.
 
 This native OpenShell design supersedes the original host-side stdio-to-HTTP proxy proposed in NVIDIA/NemoClaw#566.
 NemoClaw does not accept an inline secret-and-command tuple, persist a raw MCP service credential, or operate a host-side MCP data-plane process.

@@ -39,6 +39,16 @@ NemoClaw cannot make an upstream release mutable source trustworthy after public
 `install-openshell-version-check.test.ts` compares all eight archive mappings with the checked-in installer table, and `docker-driver-gateway-runtime.test.ts` locks the stable supervisor default while preserving an explicit operator override.
 These version-specific pins are removed only when NemoClaw drops `0.0.72` support or replaces them with independently verified artifacts for a newly supported release.
 
+### Dev Channel Opt-In
+
+- `invalidState`: A mutable development artifact is installed without SHA-256 verification or an explicit operator risk acknowledgment.
+- `sourceBoundary`: NVIDIA/OpenShell owns the mutable `dev` tag; NemoClaw owns the opt-in that permits consuming it for pre-release compatibility tests.
+- `whyNotSourceFix`: NemoClaw cannot make an upstream development tag immutable, so it must fail closed unless the operator explicitly accepts that unverified install.
+- `regressionTest`: `test/install-openshell-version-check.test.ts` proves the development channel fails without `NEMOCLAW_ACCEPT_DEV_UNVERIFIED_INSTALL=1` and succeeds with it.
+- `removalCondition`: Remove the opt-in when NemoClaw no longer tests unreleased OpenShell builds or the development channel publishes artifacts through an independently verified immutable pipeline.
+
+The development channel is compatibility evidence only. Use it in trusted test environments, never as the stable shipping configuration.
+
 ## Round-Trippable Policy Boundary
 
 OpenShell `0.0.72` reserves the `_provider_*` network-policy namespace for provider composition.

+If deletion is refused, NemoClaw attempts to restore the previous MCP state, reports any rollback failure, and preserves recovery state.
 Provider deletion and registry cleanup happen only after OpenShell confirms that the sandbox is gone.

+Provider deletion still requires the exact recorded provider ID, type, and credential key, and policy deletion still requires exact owned content; force never claims an unowned or drifted provider or same-key live policy.
 If any cleanup step leaves a residual, the command exits nonzero and preserves the managed MCP registry entry so cleanup can be retried.
 It never detaches the provider from other sandboxes, so a residual provider may require manual cleanup.

 NemoClaw unregisters the sandbox agent adapter, prechecks and removes the recorded OpenShell provider, removes the owned generated policy, and clears the sandbox registry entry.
+Deep Agents teardown does not require the managed launcher marker from the old image, so an existing compatible MCP entry cannot block `mcp remove`, sandbox rebuild, or destroy merely because the image predates that probe.

 The command fails closed on observed drift. `--force` may remove a modified same-name agent adapter entry, but provider deletion still requires the exact recorded ID, type, and credential key and policy deletion still requires exact owned content.

+NemoClaw v0.0.73 advances to OpenShell `0.0.72` and adopts its safe policy round-trip boundary:
 
 - Stable installs pin OpenShell `0.0.72` release artifacts and supervisor image, adding MCP Streamable HTTP and JSON-RPC request-policy enforcement.
 - Policy mutations now read the round-trippable base policy instead of the effective policy, preventing provider-composed `_provider_*` entries from being sent back through `policy set` while preserving existing MCP rules.

+- Advisory result: `0` known vulnerabilities across the resolved production dependency graph; npm verified registry signatures for all `120` resolved packages and attestations for `12` packages.
 
 Both image paths install the committed graph with `npm ci --ignore-scripts --omit=dev` because the published package declares no install-time lifecycle script and NemoClaw needs only its already-built CLI.
 Disabling scripts also prevents transitive packages from executing lifecycle code during the trusted image build.
 The lock records the exact version, registry URL, and integrity for every transitive package; the top-level registry integrity check remains an independent control.
+
+## Source-of-Truth Boundary
+
+- `invalidState`: the image installs a package graph, tarball, license, or advisory state that differs from the independently queried npm registry records for `mcporter@0.7.3`.
+- `sourceBoundary`: npm owns registry metadata, tarball integrity, provenance signatures, and advisory responses; NemoClaw owns the exact lock, script-disabled install, Docker integrity assertion, and review record.
+- `whyNotSourceFix`: a repository note cannot make external registry state trustworthy, so image builds execute `npm audit` and `npm audit signatures` against the locked production graph and reviewers compare the lock with the registry response.
+- `regressionTest`: `test/mcporter-supply-chain.test.ts` keeps the version, integrity, lock metadata, Docker install flags, audit commands, and this review synchronized.
+- `removalCondition`: remove this runtime dependency and review when OpenClaw provides the required authenticated Streamable HTTP client lifecycle without mcporter, or repeat the independent review for a newly pinned version.

 If a Hermes sandbox is alive but its gateway is not running after a supervisor or container restart, run `$$nemoclaw <sandbox> recover` before retrying the MCP command.
 Recovery re-establishes the managed Hermes service lifecycle, API forwarding, and the exit-75 reload loop used for transactional MCP configuration changes.
 
+If a mutating MCP command times out waiting for the per-sandbox lifecycle lock, first confirm that no `mcp add`, `mcp restart`, `mcp remove`, `rebuild`, or `destroy` command for that sandbox is still running, then retry the original command.
+Every mutating command automatically recovers a lock whose local process is provably dead or whose PID now has a different process-start identity, including locks left while stale-lock cleanup was in progress.
+NemoClaw deliberately does not expose a force-unlock flag: a live owner, a different host or PID namespace, or an incomplete legacy owner record fails closed because removing it could overlap a provider, policy, or adapter mutation.
+For a state directory shared across hosts or PID namespaces, resolve the owner on that host or stop sharing the state directory before retrying; do not delete the lock file while ownership is ambiguous.
+
 Stdio-only MCP servers are not supported.
 NemoClaw does not start, wrap, or translate them, so configure a native Streamable HTTP MCP endpoint.

+
+NemoClaw v0.0.71 improves gateway recovery, OpenShell gateway authentication, policy provenance, uninstall safety, Windows bootstrap diagnostics, messaging behavior, and inference guidance.
+
+- Gateway lifecycle operations use a host-mediated control path for built-in OpenClaw and Hermes sandboxes.
+  `recover` and `gateway restart` target the supervised gateway through the supported topology controller, re-check forwards after replacement, preserve explicit runtime model overrides during OpenClaw reconciliation, and write guard-chain recovery warnings into the gateway log for crash-loop diagnosis.
+  For more information, refer to [Manage Sandbox Lifecycle](../manage-sandboxes/lifecycle), [NemoClaw CLI Commands Reference](../reference/commands), [Troubleshooting](../reference/troubleshooting), and [Trusted Computing Base](../security/trusted-computing-base).
+- OpenShell 0.0.71 is the validated gateway release for this train.
+  NemoClaw generates local TLS, mTLS, and sandbox JWT material for Docker-driver gateways, keeps gateway binds on loopback while JWT auth is active, and documents the explicit compatibility-container boundary for older trusted Linux hosts.
+  For more information, refer to [OpenShell 0.0.71 Review](../security/openshell-0.0.71-gateway-auth-review), [Security Best Practices](../security/best-practices), and [Troubleshooting](../reference/troubleshooting).
+- Network policy output now explains why active presets are present.
+  `policy-list` annotates verified active presets with tier, agent, user-added, or source-unverified provenance; Restricted onboarding suppresses agent-required preset additions; the Balanced tier no longer includes `weather`; and the `weather` preset covers read-only `wttr.in` lookups when you add it explicitly.
+  For more information, refer to [Network Policies](../reference/network-policies), [NemoClaw CLI Commands Reference](../reference/commands), and [Common NemoClaw Integration Policy Examples](../network-policy/integration-policy-examples).
+- Day-two maintenance paths are more explicit.
+  `$$nemoclaw uninstall --destroy-user-data` provides a visible full-purge flag while keeping `--yes` non-destructive for preserved user data, custom Dockerfile onboarding documents cold and warm build-cache behavior, and host-side OpenClaw `agent` dispatch warns on stderr when a recent shields auto-relock may explain a failed one-shot command.
+  For more information, refer to [Manage Sandbox Lifecycle](../manage-sandboxes/lifecycle) and [NemoClaw CLI Commands Reference](../reference/commands).
+- Messaging and inference setup have clearer runtime defaults and selection guidance.
+  Microsoft Teams channel setup uses final-message delivery by default and runtime mention hints, non-interactive Ollama setup refuses unsafe loopback rewrites when sudo evidence is unavailable, compatible local endpoint docs explain the default chat-completions path, and the inference guide adds model task-fit and capability-audit guidance.
+  For more information, refer to [Messaging Channels](../manage-sandboxes/messaging-channels), [Use a Local Inference Server](../inference/use-local-inference), [NemoClaw Inference Options](../inference/inference-options), and [Model Capability Audit](../inference/model-capability-audit).
+- Windows setup output is safer to share during troubleshooting.
+  The Windows bootstrap redacts PowerShell transcript metadata and temporary paths from WSL install output, and it asks for a reboot only when WSL reports one is required.
+  For more information, refer to [Prepare Windows for NemoClaw](../get-started/prerequisites/windows-preparation) and [Troubleshooting](../reference/troubleshooting).

 Wildcard gateway binds remain rejected while gateway JWT authentication is active.
 Review this fallback at every stable OpenShell bump and remove it in the same NemoClaw release that raises every supported Linux host to OpenShell's native glibc floor and passes the exact-head gateway-authentication and gateway-upgrade matrix without the flag.
 
+### Compatibility Container Opt-In
+
+- `invalidState`: A host below OpenShell's native glibc floor silently receives a privileged compatibility path, or the path is treated as equivalent to native execution even though read-only Docker socket access still exposes privileged Docker APIs.
+- `sourceBoundary`: OpenShell owns its native glibc floor; NemoClaw owns the explicit `NEMOCLAW_OPENSHELL_GATEWAY_CONTAINER_PATCH=1` opt-in, host-networking configuration, read-only socket mount, and gateway authentication controls.
+- `whyNotSourceFix`: NemoClaw cannot make an upstream binary support an older host libc, so supported legacy hosts require an explicit, audited container boundary until the host floor is raised.
+- `regressionTest`: `test/install-openshell-version-check.test.ts` proves the flag gates the fallback, while `src/lib/onboard/docker-driver-gateway-compat-container.test.ts` covers container launch, the trust boundary, and the glibc decision.
+- `removalCondition`: Remove the fallback when every supported Linux host meets OpenShell's native glibc 2.28-or-newer floor and the exact-head gateway-authentication and gateway-upgrade matrix passes without the flag.
+
 The release source boundary is the immutable upstream tag, its GitHub release asset digests, and the GHCR manifest digest produced by the linked release workflow.
 A mutable tag, a digest copied from another release, or a checksum file that disagrees with NemoClaw's table is an invalid state.
 NemoClaw cannot make an upstream release mutable source trustworthy after publication, so the installer independently pins every consumed archive and the stable runtime uses the immutable supervisor manifest.

 The `tavily` preset only opens egress to `api.tavily.com:443`.
+Attaching the credential provider alone does not authorize the managed Python interpreter; the explicit policy preset is the interpreter-level opt-in.
 Keep `TAVILY_API_KEY` in the host shell only; the gateway injects it at egress, and the sandbox never sees the raw value.
 Because OpenShell attributes the harness's calls to the sandbox `python3` interpreter, this egress is process-wide for sandbox Python rather than a `dcode`-only boundary.

 The `tavily` preset only opens egress to `api.tavily.com:443`.

+Export `TAVILY_API_KEY` only for registration, then remove it from the host shell; the gateway injects the stored value at egress, and the sandbox never sees the raw value.
 Because OpenShell attributes the harness's calls to the sandbox `python3` interpreter, this egress is process-wide for sandbox Python rather than a `dcode`-only boundary.

 Endpoint paths must be literal and canonical, so NemoClaw rejects percent escapes, backslashes, semicolons, OpenShell glob metacharacters, and explicit port zero.
 NemoClaw resolves public hostnames before registration, rejects private, local, and special-use targets, and pins the resolved addresses in the generated policy.
 OpenShell re-resolves the hostname for each new connection, requires every current answer to match those pinned `allowed_ips`, and connects to the same validated socket addresses.

 A DNS change to a private, special-use, or otherwise unpinned address therefore fails closed instead of widening the route.
+The live `network-policy` lane verifies this OpenShell contract independently of NemoClaw's MCP commands and all three agent adapters: it applies a raw `protocol: mcp` policy with `allowed_ips: [1.1.1.1]`, remaps the hostname to a reachable private runner address, sends a raw MCP `tools/list` request, requires an exact HTTP 403, and verifies that the upstream server recorded zero requests.
 `restart` resolves the hostname again before updating that policy.
 Authenticated MCP rejects `host.openshell.internal`, `host.docker.internal`, and `host.containers.internal` on stable OpenShell `v0.0.72`.
 That release has a trusted-gateway branch for one narrow link-local topology, but it does not expose an attested driver gateway address that NemoClaw can pin; non-link-local driver aliases otherwise fall back to mutable exact-host resolution.

 The live MCP scenario registers a hostname while it resolves to a pinned public address, remaps it to a reachable unpinned runner address, and sends an MCP `tools/list` request beneath each adapter runtime identity.
 OpenClaw uses the managed Node identity, Hermes uses its managed Python identity, and LangChain Deep Agents Code uses its managed virtual-environment Python identity.

 `restart` resolves the hostname again before updating that policy.
 Authenticated MCP rejects `host.openshell.internal`, `host.docker.internal`, and `host.containers.internal` on stable OpenShell `v0.0.72`.
 That release has a trusted-gateway branch for one narrow link-local topology, but it does not expose an attested driver gateway address that NemoClaw can pin; non-link-local driver aliases otherwise fall back to mutable exact-host resolution.

-Live E2E projects retry failed tests automatically in CI. The default is
-2 retries after the first failure (3 total attempts). Local opt-in runs default
-to no full-test retry; set `NEMOCLAW_E2E_RETRIES=<count>` to override either
-local or CI behavior. Overrides are capped at 5 retries so a typo cannot create
-unbounded credentialed live infrastructure attempts.
+Live E2E projects do not retry an entire failed test. These tests mutate host,
+Docker, gateway, and sandbox state, so re-entering one on the same runner can
+replace the original failure with stale-lock, storage-exhaustion, or ownership
+noise. A target may retry a transient operation only inside its own cleanup
+boundary. Retry a full target by starting a fresh workflow run and runner.
 
 The retired `--emit-matrix` and `--plan-only` paths must not be reintroduced.

Subject: [PATCH 363/384] fix(mcp): recover Hermes gateway before mutation

After repeated exact not-ready probes, use the authenticated managed gateway controller once and require a fresh ordinary-helper lifecycle proof before any MCP side effect. Fail closed on integrity, health, busy, or malformed controller responses and keep the concurrent Hermes live clients alive through the bounded recovery window.

Subject: [PATCH 364/384] fix(mcp): recognize wrapped Hermes gateway

Treat Hermes' bounded PID metadata only as a candidate when the active runtime lock is held, then retain same-UID, trusted-launcher, managed-parent, and stable start-time checks. Use idempotent managed recovery for a not-ready gateway so healthy instances are not destructively restarted before MCP mutation.

Subject: [PATCH 365/384] fix(mcp): await Hermes public API after reload

Require both the replacement gateway's internal health endpoint and the supervisor-owned public API relay before acknowledging a managed MCP reload. Recheck the replacement PID identity after readiness so a second restart cannot satisfy a stale probe.

+NemoClaw v0.0.74 advances to OpenShell `0.0.72` and adopts its safe policy round-trip boundary:
 
 - Stable installs pin OpenShell `0.0.72` release artifacts and supervisor image, adding MCP Streamable HTTP and JSON-RPC request-policy enforcement.
 - Policy mutations now read the round-trippable base policy instead of the effective policy, preventing provider-composed `_provider_*` entries from being sent back through `policy set` while preserving existing MCP rules.

 This native OpenShell design supersedes the original host-side stdio-to-HTTP proxy proposed in NVIDIA/NemoClaw#566.
 NemoClaw does not accept an inline secret-and-command tuple, persist the raw bearer value supplied through `--env`, or operate a host-side MCP data-plane process.

 `mcp list` and `mcp status` are read-only and do not require lowering shields.
 NemoClaw invokes the validated transaction helper as a one-shot ordinary `openshell sandbox exec --no-tty` command with a fixed executable path and argument shape.
 The helper runs as the normal sandbox identity, rejects the legacy root-separated runtime topology, validates the gateway PID and launcher before signaling it, updates the managed compatibility hash, verifies loopback health after reload, and rolls back the config and hashes if reload fails.
+Within the existing five-minute reload deadline, if the first signal has not converged after half the budget, the helper may send one additional `SIGUSR1` only after revalidating the current gateway identity and its managed parent.
+Success still requires a replacement gateway identity, healthy loopback endpoints on internal port `18642` and public port `8642`, and a stable final identity; timeout diagnostics preserve the furthest safely observed phase, and rollback behavior is unchanged.
 There is no host listener, persistent control socket, MCP relay, or service for this operation.
 The command carries no MCP traffic or raw service credential, and its payload contains only the endpoint definition and OpenShell placeholder.
