+## Context
+
+`cloud-planner-proxy` centralizes an LLM call for Hosts that opt into
+`AI_PLANNER_TRANSPORT=cloud`, but `cloud.planner_config` currently resolves
+provider, model, and credentials from Cloud API environment variables. The
+proxy route builds a client for every decision request, so it already has a
+natural per-request configuration boundary. The Cloud Control Plane also has a
+durable SQLAlchemy repository, Alembic migrations, session-authenticated
+administrator Console, CSRF protection, and auth audit records that this
+change can reuse.
+
+The existing runtime clients instantiate provider SDKs with no arguments and
+therefore read keys from their environment. Database-backed credentials and
+an OpenAI-compatible base URL require those clients to accept explicit values
+while preserving the unchanged direct-transport default.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Let administrators manage a Cloud-wide catalog of `anthropic` and
+  `openai-compatible` planner profiles from the Cloud Console.
+- Encrypt every stored Provider API key and never return or log its plaintext.
+- Switch the provider/model used by all cloud-transport Host Agents without a
+  Host configuration change, Cloud API restart, or local credential.
+- Support OpenAI-compatible endpoints through a configurable base URL and
+  API key using the existing Chat Completions tool-calling implementation.
+- Remove Cloud API environment-based planner Provider configuration so every
+  cloud-transport decision is governed by the active database profile.
+
+**Non-Goals:**
+- Per-Host, per-user, per-task, weighted, or failover Provider selection.
+- Provider usage billing, connection-test endpoints, model discovery, or
+  support for protocols other than Anthropic native tool use and OpenAI Chat
+  Completions tool calling.
+- Arbitrary Anthropic-compatible endpoints, custom request headers, or
+  different OpenAI-compatible parameter dialects.
+- Automatic encryption-master-key rotation. Provider API key rotation is
+  supported by updating a profile; master-key rotation remains an operational
+  migration until a key-ring design is separately proposed.
+
+## Decisions
+
+### D1: Persist a profile catalog and a singleton active-profile setting
+
+Add `cloud_llm_provider_profiles` with immutable id, unique normalized name,
+provider type, model, optional base URL, timeout, encrypted API key, enabled
+state, revision, and timestamps. Add a one-row
+`cloud_llm_provider_settings` record with `database_management_enabled`,
+`active_profile_id`, revision, and timestamp. The profile table represents
+the operator's choices; the singleton holds the one Cloud-wide choice that is
+active.
+
+Activating an enabled profile updates the singleton in the same transaction
+and sets `database_management_enabled=true`. An active profile cannot be
+disabled or deleted before another enabled profile is activated. This avoids
+the ambiguity and cross-database portability problems of a partial unique
+"one active row" index, and gives PostgreSQL and SQLite one repository
+contract.
+
+Alternative considered: an `is_active` column on profiles. Rejected because
+atomic replacement and uniqueness semantics differ between SQLite and
+PostgreSQL, while a singleton pointer is explicit and makes initial
+environment-fallback state representable.
+
+### D2: Resolve the active profile on every planner decision
+
+The internal planner endpoint resolves the active profile from the repository
+at the start of each request, decrypts its API key, and builds the existing
+tool-calling client with the resolved values. It uses that same resolved
+profile for token-usage metadata, preventing a model switch during the call
+from recording a mismatched provider/model. No application-level cache is
+used; the one indexed settings lookup and symmetric decryption are negligible
+relative to an LLM request and make a successful activation effective on the
+next decision.
+
+The resolver fails a planner request with the existing structured
+`planner_unavailable` response when the active profile is missing, disabled,
+corrupt, or undecryptable. It never reads legacy `AI_PLANNER_*` or Provider
+API-key environment variables.
+
+Alternative considered: move profile configuration into Host Agent heartbeat
+responses. Rejected because it would replicate API keys to edge hosts, delay
+changes until heartbeat, and duplicate the Cloud proxy's existing decision
+boundary.
+
+### D3: Use Fernet encryption with an environment-held master key
+
+`cryptography` is added to `device-cloud-platform`. A small secret-box port
+uses `cryptography.fernet.Fernet` with
+`CLOUD_LLM_PROVIDER_ENCRYPTION_KEY`; only Fernet ciphertext is stored in the
+database. The key remains environment or secret-manager configuration and is
+not stored in the database. Profile write requests accept a plaintext API key
+only to encrypt it; profile read responses expose `has_api_key` and
+`key_last_rotated_at` rather than a key value.
+
+The Cloud API can list profile metadata without the encryption key, but
+creating, rotating, activating, or resolving a profile without a valid key
+fails with a controlled configuration error that excludes the supplied secret.
+Provider mutation audit events retain profile id and action only.
+
+Alternative considered: plaintext database keys. Rejected because database
+backup or read access would expose external-provider credentials. Alternative
+considered: a database-held master key. Rejected because it does not create a
+separate protection boundary.
+
+### D4: Treat OpenAI-compatible as a concrete wire-protocol contract
+
+Profiles have `provider_type` of `anthropic` or `openai-compatible`. An
+`openai-compatible` profile may omit `base_url` to use the official OpenAI
+endpoint, or supply an absolute HTTP(S) base URL for a compatible service.
+The runtime `OpenAIToolCallingClient` gains optional `api_key` and `base_url`
+constructor arguments and constructs `OpenAI` explicitly when supplied.
+`AnthropicToolCallingClient` gains an optional explicit API key for cloud-held
+credentials; absent optional arguments retain current SDK environment
+behavior for direct transport.
+
+Compatibility means the endpoint accepts OpenAI Chat Completions requests
+with the tool/function-calling fields emitted by the existing client and
+returns a single compatible tool call. It does not claim compatibility with
+providers requiring a different request schema or custom authentication.
+
+Alternative considered: create a new cloud-only HTTP adapter. Rejected because
+it duplicates response parsing and would drift from the direct provider path.
+
+### D5: Expose a dedicated administrator API and Console view
+
+Add a public `/v1/planner/providers` router composed by the Cloud API. It
+requires a new `llm-providers:admin` scope, which the existing admin role
+receives via its wildcard. All writes use the existing session CSRF validator
+and record non-secret auth audit events. The Console shows only for principals
+with that scope and provides profile creation, editing/key rotation,
+enable/disable, activation, and deletion of inactive profiles. Responses use
+revisions for optimistic-concurrency conflicts rather than overwriting an
+administrator's newer edit.
+
+Alternative considered: reuse a generic configuration endpoint. Rejected
+because Provider records carry secrets and need substantially stricter output,
+audit, and activation invariants.
+
+## Risks / Trade-offs
+
+- [Risk] The Cloud database and encryption key become part of the planner hot
+  path. -> Mitigation: resolver failures use the established fail-fast
+  response, and readiness/configuration documentation makes the required
+  active profile explicit.
+- [Risk] An administrator can direct Cloud traffic to an arbitrary compatible
+  base URL. -> Mitigation: only `llm-providers:admin` can write a profile;
+  deployments must treat that role as privileged network-configuration access.
+- [Risk] Losing the master key makes stored Provider credentials unusable. ->
+  Mitigation: document secret-manager backup and keep a legacy deployment
+  rollback path while adopting the feature.
+- [Risk] Some services marketed as OpenAI-compatible diverge on parameters or
+  tools. -> Mitigation: document the exact Chat Completions tool-calling
+  contract and surface provider failures instead of retrying against another
+  profile.
+- [Risk] Concurrent Console administrators can race to edit or activate a
+  profile. -> Mitigation: revision checks on profile/settings writes and a
+  transaction for activation.
+
+## Migration Plan
+
+1. Apply the migration and provision `CLOUD_LLM_PROVIDER_ENCRYPTION_KEY` from
+   the deployment secret manager before routing cloud-transport planner work
+   to the new Cloud API version.
+2. Create and activate a profile through the administrator Console. Until an
+   active profile exists, cloud planner requests fail closed.
+3. Verify profile metadata and token-usage provider/model labels, then remove
+   `AI_PLANNER_*`, `ANTHROPIC_API_KEY`, and `OPENAI_API_KEY` from the Cloud API
+   deployment configuration.
+4. To roll back, restore a previous Cloud API version together with its legacy
+   environment configuration. Do not remove the encryption key or database
+   rows before a planned migration.
+
+## Open Questions
+
+- None for the initial Cloud-wide selection. Per-Host assignment, cost-aware
+  routing, and master-key rotation need separate designs because they change
+  the selection and operational contracts.

+## Why
+
+The Cloud Control Plane proxy currently reads its LLM provider, model, and
+credentials from process environment variables. Changing a model therefore
+requires a deployment change and cannot be audited or operated from the Cloud
+Console, even though every cloud-transport Host Agent already depends on the
+control plane for its planner decisions.
+
+## What Changes
+
+- Add a durable, Cloud-wide catalog of planner Provider profiles. Each profile
+  records its supported provider kind (`anthropic` or `openai-compatible`),
+  model, timeout, optional OpenAI-compatible base URL, enabled state, and an
+  encrypted API key.
+- Add an administrator-only Cloud API and Cloud Console view to create, list,
+  update, activate, disable, and retire Provider profiles. Read responses
+  never expose an API key; writes can rotate a key without returning it.
+- Make the cloud planner-decision endpoint resolve the active profile from the
+  database for each request, so a newly activated profile applies to all
+  cloud-transport Host Agents without changing their configuration or
+  restarting them.
+- Remove Cloud API environment-variable configuration for the planner
+  provider, model, timeout, and Provider API keys. An absent active database
+  profile fails closed instead of silently using a stale environment
+  credential.
+- Add an encryption-key configuration for protecting Provider API keys at rest
+  and document deployment, rotation, and migration behavior.
+- Extend the existing provider client construction so cloud-managed
+  OpenAI-compatible profiles pass their encrypted API key and configured base
+  URL explicitly to the OpenAI SDK, while Host Agent direct transport continues
+  to use its existing environment-based credentials.
+
+## Capabilities
+
+### New Capabilities
+- `llm-provider-management`: Durable, administrator-managed Cloud-wide LLM
+  Provider profiles, encrypted credential handling, and Console/API operations.
+
+### Modified Capabilities
+- `cloud-planner-proxy`: Cloud planner decisions select their provider,
+  model, timeout, and credential from the active database profile once
+  database management is enabled, rather than requiring a Cloud API restart
+  and environment-variable change.
+
+## Impact
+
+- `packages/cloud-platform/cloud`: SQLAlchemy models, repository contract and
+  implementation, Alembic migration, encrypted-secret service, and planner
+  client construction from a resolved profile.
+- `apps/cloud-api` and `cloud.sdk`: an authenticated management router and
+  application composition for the new service.
+- `cloud-console`: an administrator-only Provider management view, client API,
+  and types.
+- Cloud deployment configuration: the encryption key remains deployment-held,
+  while planner Provider/model/timeout/API-key environment variables are
+  removed.

+## MODIFIED Requirements
+
+### Requirement: Endpoint resolves exactly one tool-call decision using cloud-held provider configuration
+The Cloud Control Plane SHALL use its own configured LLM provider, model, and
+credentials -- not any value supplied by the requesting Host Agent -- to
+resolve a planner-decision request to exactly one tool name and one arguments
+object, within the request's timeout. The endpoint SHALL resolve the active
+database-managed Provider profile for every request and use its provider,
+model, timeout, OpenAI-compatible base URL when applicable, and encrypted
+cloud-held credential. It SHALL NOT read Cloud API planner Provider/model/
+timeout/API-key environment variables.
+
+#### Scenario: Provider returns a usable decision
+- **WHEN** the configured provider responds to a planner-decision request
+  with a tool call
+- **THEN** the Cloud Control Plane returns exactly one resolved tool name
+  and arguments object to the requesting Host Agent
+
+#### Scenario: Configured provider is unreachable or misconfigured
+- **WHEN** the Cloud Control Plane's configured provider call fails (for
+  example, invalid credentials, provider error, or timeout)
+- **THEN** the endpoint returns a structured failure response rather than a
+  fabricated decision, and does not crash the Cloud Control Plane process
+
+#### Scenario: Database profile is the only planner configuration source
+- **WHEN** the Cloud API process has legacy planner environment variables
+- **THEN** subsequent planner-decision requests use only the active database
+  profile and do not read a legacy Provider credential for that decision

+## ADDED Requirements
+
+### Requirement: Cloud-wide LLM Provider profiles are durable and validated
+The Cloud Control Plane SHALL persist administrator-managed LLM Provider
+profiles with a unique name, provider type, model, timeout, enabled state,
+revision, and timestamps. A profile's provider type SHALL be either
+`anthropic` or `openai-compatible`; an OpenAI-compatible profile MAY specify
+an absolute HTTP(S) base URL and SHALL use the official OpenAI endpoint when
+it does not.
+
+#### Scenario: Administrator creates an OpenAI-compatible profile
+- **WHEN** an authorized administrator submits a unique profile name,
+  `openai-compatible` provider type, model, valid timeout, API key, and an
+  optional valid base URL
+- **THEN** the Cloud Control Plane persists an enabled profile with a new
+  revision and returns its non-secret metadata
+
+#### Scenario: Invalid profile configuration is rejected
+- **WHEN** an administrator submits an unsupported provider type, blank model,
+  non-positive timeout, duplicate name, or invalid base URL
+- **THEN** the Cloud Control Plane rejects the write without creating or
+  changing a profile
+
+### Requirement: Provider API keys are encrypted and never disclosed
+The Cloud Control Plane SHALL encrypt Provider API keys before persistence
+using a deployment-held encryption key, and SHALL not expose plaintext keys in
+read responses, validation errors, audit records, or application logs.
+
+#### Scenario: Provider profile is listed after creation
+- **WHEN** an authorized administrator lists Provider profiles after creating
+  one with an API key
+- **THEN** every response reports only key-presence and rotation metadata and
+  does not contain the submitted API key or its ciphertext
+
+#### Scenario: Encryption configuration is unavailable
+- **WHEN** a database-managed profile is created, rotated, activated, or
+  resolved without a valid deployment encryption key
+- **THEN** the operation fails with a controlled configuration error that does
+  not reveal an API key
+
+### Requirement: Administrators can manage and activate Provider profiles
+The Cloud Control Plane SHALL expose session-CSRF-protected and scope-guarded
+operations to list, create, update, rotate a key, enable, disable, activate,
+and delete inactive LLM Provider profiles. Mutating operations SHALL require
+the `llm-providers:admin` scope and record a non-secret audit event.
+
+#### Scenario: Non-administrator attempts to modify a profile
+- **WHEN** a principal without `llm-providers:admin` invokes a Provider
+  mutation endpoint
+- **THEN** the Cloud Control Plane rejects the request before decrypting or
+  modifying a Provider credential
+
+#### Scenario: Administrator switches the active profile
+- **WHEN** an authorized administrator activates an enabled profile
+- **THEN** the Cloud Control Plane atomically selects that profile as the one
+  Cloud-wide active profile and records the activation without retaining an
+  API key in the audit event
+
+#### Scenario: Administrator attempts to retire the active profile
+- **WHEN** an administrator attempts to disable or delete the active profile
+  before activating a replacement
+- **THEN** the Cloud Control Plane rejects the operation and preserves the
+  active profile selection
+
+### Requirement: Activation dynamically selects one Provider for cloud transport
+The Cloud Control Plane SHALL resolve the active database-managed profile for
+each Cloud planner decision and SHALL apply an activation to subsequent
+requests without requiring a Cloud API restart or any Host Agent
+reconfiguration.
+
+#### Scenario: A Host requests a decision after a model switch
+- **WHEN** an administrator activates a different enabled profile and a
+  cloud-transport Host Agent submits its next planner-decision request
+- **THEN** the Cloud Control Plane calls that profile's provider, model,
+  timeout, base URL, and API key while the Host Agent continues using the same
+  Cloud Control Plane endpoint
+
+#### Scenario: Active OpenAI-compatible profile is used
+- **WHEN** the active profile is OpenAI-compatible and includes a base URL
+- **THEN** the Cloud Control Plane makes the existing OpenAI Chat Completions
+  tool-calling request to that base URL using the profile's decrypted API key
+  and returns the resulting single tool-call decision
+
+### Requirement: Cloud planner Provider configuration is database-only
+The Cloud Control Plane SHALL resolve Cloud planner Provider, model, timeout,
+base URL, and API key from the active database profile and SHALL NOT read
+planner Provider/model/timeout or Provider API-key environment variables.
+When no usable active profile exists, it SHALL fail a planner request with a
+structured unavailable response.
+
+#### Scenario: Active profile is unavailable
+- **WHEN** the active database Provider profile is missing, disabled, or
+  cannot be decrypted
+- **THEN** the planner decision fails without invoking a legacy
+  environment-configured Provider
+
+#### Scenario: Legacy environment variables are present
+- **WHEN** the Cloud API process has legacy planner Provider or API-key
+  environment variables but an active database profile exists
+- **THEN** the planner decision uses only the active database profile
