Problem

Three credential fields still accepted only plaintext, unlike the other secret fields: Simlock agentToken, Antigravity apiKey and OpenCode serverPassword.

Change

• All three are typed SettingsSecretValue, so the settings forms show the secret source picker and the server resolves them.
• Simlock: the host reads the token each time it needs it instead of once at build, so an unlocked or rotated secret works without a restart. An unreadable reference fails with the usual "Could not read the credential from the secret provider…" and never falls back to AGENT_DEVICE_DAEMON_AUTH_TOKEN. Each lease keeps the token it opened with, so it can still be released after the secret becomes unreadable. The token check RPC accepts a reference too. The Settings refresh now also invalidates Simlock references. The web editor uses SecretSourceInput.
• Antigravity and OpenCode: ProviderInstanceRegistry already resolves references in config fields typed this way and marks the instance unavailable when it can't; the drivers only narrow the type.
• Older clients: the existing legacy projection shows all three as a saved secret, and saving that back keeps the reference. The strict-reference tripwire now lists simlockDeviceHosts.[].agentToken on purpose.

Verification

• Extended existing tests: legacy projection and echo for all three, the tripwire, SimlockDeviceHost.test.ts (reference read; unreadable fails with no gateway requests even with an env token for the same gateway), a ProviderInstanceRegistry.test.ts row per driver schema, a refresh invalidation case, and the web save plan. The affected server tests fail on main.
• vp run check:changed passes.
• Not checked in a real client.

Approvability

Verdict: Approved at a20cccd

Macroscope's review found this PR approvable — Adds optional secret-provider credentials for Simlock, Antigravity and OpenCode while retaining literal credentials and existing defaults. Unreadable references fail closed, and Simlock preserves gateway scoping and lease cleanup credentials.

Walkthrough

Simlock, Antigravity, and OpenCode credential settings now accept secret references. Server code resolves or extracts credential values for device and provider operations. The Simlock editor supports secret-source selection, and settings handling covers reference redaction, preservation, and invalidation.

Changes: Secret-backed settings and credentials

Layer / File(s)	Summary
Secret-value contracts and Simlock editor packages/contracts/src/device.ts, packages/contracts/src/settings.ts, packages/provider-opencode/src/settings.ts, apps/web/src/components/settings/simlockDeviceHostsSettings.logic.ts, apps/web/src/components/settings/simlockDeviceHostsSettings.logic.test.ts, apps/web/src/components/settings/SimlockDeviceHostEditor.tsx	Simlock, Antigravity, and OpenCode credential fields accept SettingsSecretValue. The Simlock editor supports secret references, validates them, and preserves them in save plans.
Simlock credential resolution and lease use apps/server/src/device/DeviceService.ts, apps/server/src/device/SimlockDeviceHost.ts, apps/server/src/device/SimlockDeviceHost.test.ts	Simlock resolves entered and configured token references. It uses credentials for matching gateway origins and stores the opening token on each lease for later requests.
Provider credential resolution and use apps/server/src/provider/Drivers/AntigravityDriver.ts, apps/server/src/provider/ProviderInstanceRegistry.ts, apps/server/src/provider/ProviderInstanceRegistry.test.ts, packages/provider-opencode/src/server/*	Antigravity and OpenCode extract secret literals for authentication and server connections. The provider registry treats missing, empty, and whitespace-only secrets as unreadable.
Settings redaction and secret invalidation apps/server/src/serverSettings.test.ts, apps/server/src/sourceControl/sourceControlHostSecrets.ts, apps/server/src/sourceControl/sourceControlHostSecrets.test.ts	Settings tests check redaction and preservation of Simlock and provider secret references. Secret invalidation includes Simlock token references.

Merge Risk: Moderate · up to a20cc

Refreshing settings after blanking a provider secret can leave the provider running with its previous credential. Correct that transition before merging.

- Around line 343-345: Extend the existing lease-release test around
`ready.devices.agentEndpoint` to make the reference unreadable after opening and
configure the fake CLI `close` to fail. Add fake-pool support to record the
fallback HTTP `DELETE` authorization header, then assert it uses the token
captured during opening.

Review comments at @packages/provider-opencode/src/settings.ts:
- Line 40: Update ProviderInstanceRegistry.readInstanceSecrets to treat resolved
secret values that are empty or whitespace-only as unreadable for both
environment and config references, before passing them to provider creation.
Preserve the original non-empty secret value and the existing missing-credential
behavior; do not add a separate fallback change for Antigravity.
