Summary

Pre-existing sandboxes now recover before generic installer host admission. CPU-only sandboxes therefore retain their recorded GPU opt-out during upgrades, while fresh onboarding and DGX Station reconciliation still pass through host preflight.

Related Issue

Fixes #10389

Changes

  • Run pre-existing sandbox recovery before deciding whether generic onboarding needs host admission.
  • Skip generic host admission when recovery completes and no onboarding remains.
  • Preserve host admission for fresh onboarding and DGX Station reconciliation, while keeping recovery failures fail-closed.
  • Add control-flow regression coverage for CPU-only recovery, Station reconciliation, fresh onboarding, and recovery failure.
  • Confirm no documentation update is needed because existing upgrade docs already describe recovery before generic onboarding.

Type of Change

  • Code change (feature, bug fix, or refactor)
  • Code change with doc updates
  • Doc only (prose changes, no code sample modifications)
  • Doc only (includes code sample changes)

  • Sensitive-path review completed or maintainer-approved waiver recorded — reviewer/approval link/justification: Control-flow review confirmed failed recovery still returns nonzero before onboarding, while fresh and Station onboarding retain host admission; focused tests cover each boundary.
  • Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue:

Review Change Stack

📝 Walkthrough

Walkthrough

The installer preserves portable Docker context state across group re-execution, validates Docker targets, separates recovery from host preflight and onboarding, and classifies recovery verification results. Tests cover these paths, runtime replacement, Station handling, output guidance, and phase ordering.

Changes

Sandbox onboarding

Layer / File(s) Summary
Docker target and runtime context handling
scripts/install.sh, test/install/install-docker-group-reexec.test.ts
The installer validates Docker targets, defers Node-dependent checks, preserves portable context state across re-execution, and prepares runtime targets.
Recovery verification and status classification
scripts/install.sh, test/install/install-orphaned-sandbox-recovery.test.ts, test/install/install-preexisting-sandbox-recovery.test.ts
Recovery tracks command and log-writing status separately. It classifies recovery as confirmed, orphaned, or unconfirmed and prints remediation guidance.
Preflight and onboarding routing
scripts/install.sh, test/install/install-onboard-yes.test.ts, test/install/install-preexisting-sandbox-recovery.test.ts
The installer separates recovery, host preflight, Station reconciliation, and onboarding. Recovery state controls whether generic onboarding runs.
Recovery and onboarding test coverage
test/install/install-preexisting-sandbox-recovery.test.ts, test/install/install-native-runtime-qualification.test.ts
Tests cover Docker-host validation, deferred context ordering, runtime replacement, recovery failures, Station reconciliation, shared fixtures, and phase ordering.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 26f8a

The installer now recovers existing sandboxes before host admission, preserving CPU-only upgrades while retaining checks for new onboarding and Station reconciliation. Current tests do not fully exercise the production recovery, preflight-ordering, and Docker-group re-execution paths, leaving a bounded integration risk that routing or context-propagation regressions could escape; the change is mergeable with explicit owner follow-up.

sandl99 pushed a commit that referenced this pull request Aug 27, 2026
… 0.0.106 (#10273)

## Summary

A sandbox reads its provider environment once, at boot, and the agent
process inherits that read for the life of the container. Any channel
credential that only becomes injectable after boot therefore never
reaches the running agent, and no restart recovers it — only recreating
the sandbox does. This change makes every messaging credential
injectable before the agent starts, and stops the agent config from
shadowing the injected value once it arrives.

## Related Issue

Part of #10079. It does not close that issue: WeChat and Teams on Hermes
are untouched here and are described below.

## Changes

- **Bind the credential in the policy preset and apply that preset at
boot.** The provider profiles are endpointless, so the binding is the
only thing that makes the token injectable, and `requiredAtCreate` is
what puts the preset in the boot policy rather than a post-boot apply.
Without both, OpenShell withholds the credential entirely (`withholding
static provider credential handle from endpointless profile`). Bindings
this PR adds:
  - Telegram — both agents.
  - Teams — OpenClaw.
  - Slack — OpenClaw; the Hermes side landed on `main` as #10271.

  Discord already carried the binding on both agents before this branch.
- **Pass the sandbox name through both policy preflights.** Channel
presets bind `{sandboxName}-<channel>-bridge`, so composing one without
a sandbox name throws. Two paths dropped the name after resolving it:
- `preflightPolicyRequirements` resolves it for the sandbox inspection.
- `prepareSandboxCreatePolicy` has it on the create intent, and is the
path the external-authority onboarding flow takes.

#10314 fixed the sibling site inside `materializeSandboxCreatePlan`;
these two were still uncovered. Four tests composed presets directly and
mirrored the old shape, which let the composition error escape the test
body and kill a whole vitest shard.
- **Stop persisting the canonical placeholder in agent config.**
OpenShell 0.0.106 refuses the canonical form once a credential is
identity-bound, so the shape that used to work is now the one shape the
credential endpoint rejects. Removed:
- OpenClaw config — `botToken` for Telegram, `botToken` and `appToken`
for Slack, `appPassword` for Teams.
- Hermes `~/.hermes/.env` — the Telegram, Slack, and Discord token
lines.
- The Slack manifest's legacy `slackRuntimeEnvAliases` normalization,
which existed only to rewrite those placeholders.

Each agent now reads the key from its process environment, which
OpenShell fills with the revision-scoped placeholder at boot.
- **Prune stale credential keys from the Hermes env file.** Hermes loads
`~/.hermes/.env` with `override=True`, so a leftover canonical
placeholder from an earlier onboarding shadows the injected process
value and the channel stays unauthenticated. Four gaps kept that line
alive:
- Cleanup lived only in `applyAgentConfigAtOpenShell`, whose sole
production caller returns early for any non-OpenClaw plan. The Hermes
runtime applier merged env lines and never removed any.
- `readEnvLineKey` read `export KEY` as the key, so an export-prefixed
assignment matched nothing.
- Deletion keys came from the persisted plan, so a binding naming an
unrelated key could remove an operator-owned line.
- A plan encoded before the credential moved to a policy binding still
carries the token in `agentRender`, and rebuild refreshes only host
forwards and runtime setup, so the render reintroduced the line the
cleanup had just removed.

The rules now live in one module both appliers use: read the key from
either assignment form, take deletion authority from the channel
manifest rather than persisted state, treat a rendered key as wanted
only while the manifests still assign a credential to it, and visit an
owned target even when the plan renders nothing into it. WeChat and
Teams render their Hermes credential under a different key than the
provider env key, so the assignment metadata, not the provider key,
decides what survives. Each rule was checked by removing it and
confirming the new tests fail.
- **Wait for the first gateway mint before creating the sandbox.**
`provider refresh configure` returns while the credential is still the
create-time sentinel and the refresh worker mints on its own sweep, so
the sandbox was booting inside that window and pinning a revision whose
value is the sentinel. The poll itself accepted any status table it
could parse and counted attempts only, so two failure modes also passed
through:
- A nonzero `provider refresh status` can still print a stale
`refreshed` row, which was read as success.
- Attempts do not bound the wait; one probe with no timeout can hang and
the loop never reaches its cap.

It now requires exit status 0 before trusting a row, gives each probe a
command timeout, and stops at an overall deadline. Current requirement
and consumer: Google Chat, the only channel with a gateway-minted
credential. Failing closed stays correct: creating the sandbox before
the first mint pins the create-time sentinel for the life of the
container. The `configureMessagingBridgeRefreshes` tests cover the
success and the never-minted path, and the optional `sleep` dependency
is a test injection point, not a configuration surface.
- **Make the Google Chat outbound preload forward the injected
placeholder verbatim.** Rewriting it to the canonical form produced
`credential_unavailable` on every send.
- **Keep preserved Hermes env lines anchored to an enabled channel.**
They were dropped whenever no enabled channel happened to render a
`~/.hermes/.env` entry — which is now the common case, since the token
lines are gone.
- **Add two drift guards over the real policy files.** A preset that
declares `credential_binding` must be `requiredAtCreate`, and a host and
port declared twice must carry distinct path selectors. Each guard was
checked by reintroducing the defect and confirming it fails.
- **Align the Discord render assertion added by #10277.** That PR fixed
the OpenClaw half; the Hermes Discord policy already bound every
endpoint to `{sandboxName}-discord-bridge`, so rendering the canonical
placeholder into `~/.hermes/.env` wrote the one shape the credential
endpoint refuses.
- **Refresh the reviewed managed-startup bundle.**
`managed-startup-image-runtime.bundle` embeds the channel manifests, so
the manifest changes above made `bundle:reviewed:check` fail in
`static-checks`. Regenerated from the merged tree; the delta is 8
blocks, all of them the credential renders removed above plus the two
`requiredAtCreate` flags.

Three overlapping fixes landed on `main` while this PR was open and are
merged in here: #10271 (the Hermes Slack `path` selector), #10277 (the
OpenClaw half of Discord), and #10314 (binding the Discord create-path
providers). This branch keeps only an explanatory comment on
`slack/policy/hermes.yaml`; the behavior there is main's. #10314 fixed
the `materializeSandboxCreatePlan` call site; the two preflight call
sites it left uncovered are fixed here.

## Channel coverage after this change

| Channel | OpenClaw | Hermes | Status |
|---|---|---|---|
| Slack | fixed | fixed | live, bot replied — Hermes policy selector
landed separately as #10271 |
| Discord | fixed | fixed | live, bot replied — OpenClaw half landed
separately as #10277 |
| Google Chat | fixed | fixed | live, bot replied |
| Telegram | fixed | fixed | live, bot replied on both |
| Teams | fixed | not covered | withholding log observed, no live run |
| WeChat | not covered | not covered | not measured |
| WhatsApp | unaffected | unaffected | injects no provider credential
(QR pairing) |

Every `fixed` row except Teams was confirmed by an actual bot reply on a
freshly wiped host, not by test output alone. For Telegram, both agents
were run against OpenShell 0.0.106: each sandbox booted with the
revision-scoped placeholder in its agent process, the policy matched the
redacted `/bot[CREDENTIAL]/` path, and the bot answered — with no denial
and no credential error across five hours of OpenClaw polling and twenty
minutes of Hermes polling.

Out of scope here:

- **WeChat** — injects a provider credential with no endpoints on the
profile and no `credential_binding`. Telegram's shape, so the same
withholding is expected, but it was not measured, so it is not claimed.
- **Teams on Hermes** — Hermes reads `TEAMS_CLIENT_SECRET`, the provider
injects `MSTEAMS_APP_PASSWORD`. A name mismatch, not the ordering
defect.

## Known gaps, deliberately out of scope

- **Ready-sandbox reuse does not migrate messaging config.** Both reuse
branches in `sandbox-create/orchestration.ts` revalidate policy, seed
presets, upsert providers, restore the dashboard, and return. A sandbox
that booted without the injected provider environment cannot be repaired
by pruning `~/.hermes/.env` — it needs a recreate decision in the
existing drift guard beside `credentialRotation.changed`, which is a new
drift signal rather than a cleanup change. Nearest coverage: the create
and rebuild paths this PR fixes.
- **`remove-channel` on a legacy plan leaves that channel's placeholder
line behind.** `removePlanChannel()` drops the credential binding and
the render together, so cleanup has no ownership evidence for the key.
The residue is a placeholder rather than a credential, is inert once the
provider is removed, and is pruned if the channel is added again.

- [x] Sensitive paths changed (security, policy, credentials, preflight,
onboarding, inference, runner, sandbox, or messaging)
- [ ] Sensitive-path review completed or maintainer-approved waiver
recorded — reviewer/approval link/justification: outstanding; this
change touches messaging credentials, network policy presets, and the
onboarding provider path, so it needs a maintainer sensitive-path review
before merge.
- [ ] Non-success, skipped, or missing CI check accepted by maintainer —
check name, approval link, and follow-up issue: four checks are red on
this branch and none of them is reachable from it. `CLI` fails its
coverage gate on `src/lib/policy/commands.ts` at 88.88% against the 100%
threshold that #9511 declares for `src/lib/policy/{commands,merge}.ts`,
and `Required Checks` fails only because `CLI` does. `PR / Agent
runtimes / Test activation` and both `PR / OpenClaw / MCP Discovery`
runs fail on the same assertion, `Sandbox policy authority validation
failed after creation`, in `managed-image-activation-e2e.test.ts` and
`mcp-bridge.test.ts`. All four were red on #10332's own PR run before it
merged, with a byte-identical coverage error, and #10332 both rewrote
`src/lib/policy/commands.ts` and added its `commands.test.ts`. Bucketing
open PRs by base confirms the boundary: `ac3ebe9aa` (#10384, the direct
parent of #10332) passes those checks, while `1293457d3` (#10332 itself,
#10392), `1effafb3f` (#10391), and `6062006e6` (this PR, #10397) all
fail. This branch changes nothing under `src/lib/policy/`, and the
failing image runs configure no messaging channel, so no preset from
this PR is composed on that path.

104-104: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Assert the recovery-before-preflight ordering explicitly.

The child payload stubs run_installer_host_preflight as a silent no-op, and the assertions only check presence and a count of recovery-started. This harness cannot fail if scripts/install.sh moves recovery back after host preflight, which is the central behavior of this change.

Log a marker from the preflight stub and assert the marker order in the call log.

♻️ Proposed ordering seam
-run_installer_host_preflight() { return 0; }
+run_installer_host_preflight() {
+  printf 'host-preflight-started\n' >> "$BOOTSTRAP_CALL_LOG"
+  return 0
+}
     expect(result.output.match(/recovery-started/g)).toHaveLength(2);
+    expect(result.output.indexOf("recovery-started")).toBeLessThan(
+      result.output.indexOf("host-preflight-started"),
+    );

As per path instructions: "Prefer observable outcomes through the public boundary over source-text, private-shape, or mock-call assertions" and "Flag ... broad mocks that bypass the behavior under test".

In `@scripts/install.sh`:
- Around line 6461-6467: The Docker-target normalization paths must validate the
caller’s effective target before changing runtime variables. In
scripts/install.sh lines 6461-6467, update the portable branch around
capture_portable_caller_docker_context and
validate_installer_docker_target_before_host_changes to validate first, then
restore only the validated target or retain Podman onboarding. In
scripts/install.sh lines 5996-5999, capture and validate the Station caller
target before the preceding normalization at lines 5993-5994, preserving the
required onboarding context.
- Around line 4525-4530: Update the non-interactive sg docker -c re-exec in
ensure_docker so the _PORTABLE_CALLER_DOCKER_CONTEXT_CAPTURED,
_PORTABLE_CALLER_DOCKER_CONTEXT_SET, and _PORTABLE_CALLER_DOCKER_CONTEXT values
survive into the child process. Export these captured variables or pass them
explicitly, ensuring run_onboard restores the original caller DOCKER_CONTEXT
rather than recapturing the overridden state.

In `@test/install/install-preexisting-sandbox-recovery.test.ts`:
- Around line 173-180: Preserve the portable target-selection behavior in
prepare_portable_experimental_runtime_override: when
NEMOCLAW_EXPERIMENTAL_PROFILE is portable, clear DOCKER_CONTEXT and set
DOCKER_HOST to the expected Podman socket. Keep the production helper under
test, mocking only its external command dependencies rather than replacing the
helper implementation.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Exercise the production Docker-group re-execution path.

This test calls capture_portable_caller_docker_context directly and then starts a generic bash child. It does not exercise the installer path that performs Docker-group re-execution. A regression that stops the production caller from capturing or exporting the context can still pass. Invoke the production re-execution entry point and assert the child’s observable Docker context. Keep the helper-state assertions only as focused unit coverage if needed.

As per path instructions, tests must provide behavioral confidence rather than implementation lock-in.
