### Correctness (Static — Structural Evidence)

| Requirement                                | Status        | Notes                                                                                                                                                 |
|--------------------------------------------|---------------|-------------------------------------------------------------------------------------------------------------------------------------------------------|
| Provider Account Pool Configuration        | ✅ Implemented | `clients/agent-runtime/src/config/schema.rs` adds `account_pools` map + validation; `clients/agent-runtime/src/providers/mod.rs` wires pool creation. |
| Pool Selection and Per-Request Credentials | ✅ Implemented | `clients/agent-runtime/src/providers/pool.rs` selects round-robin/weighted and calls `create_provider_for_pool` with account api_key.                 |
| Account-Aware Provider Reuse               | ✅ Implemented | Per-account cache keyed by account id in `clients/agent-runtime/src/providers/pool.rs`.                                                               |
| Backward Compatibility Without Pool        | ✅ Implemented | `clients/agent-runtime/src/providers/mod.rs` falls back to base provider when no pool.                                                                |
| Secret Handling for Pooled Credentials     | ✅ Implemented | Encrypted save in `clients/agent-runtime/src/config/schema.rs`; redacted admin views in `clients/agent-runtime/src/gateway/admin.rs`.                 |
| Admin Config Exposure Controls             | ✅ Implemented | Admin API guarded by `admin_expose_provider_pools` with validation in `clients/agent-runtime/src/gateway/admin.rs`.                                   |

### Coherence (Design)

| Decision                                     | Followed? | Notes                                                                                                                        |
|----------------------------------------------|-----------|------------------------------------------------------------------------------------------------------------------------------|
| Represent pools as provider-keyed config map | ✅ Yes     | `ReliabilityConfig.account_pools` in `clients/agent-runtime/src/config/schema.rs`.                                           |
| Pooling implemented as provider wrapper      | ✅ Yes     | `AccountPoolProvider` in `clients/agent-runtime/src/providers/pool.rs` used by `clients/agent-runtime/src/providers/mod.rs`. |
| Rate-limit aware selection with cooldown     | ✅ Yes     | `mark_cooldown` + `is_rate_limited` in `clients/agent-runtime/src/providers/pool.rs`.                                        |

### Issues Found

**CRITICAL** (must fix before archive):
None

**WARNING** (should fix):

- `make build` runs `agentsync apply` and updates workspace files (e.g., `.gitignore`, MCP configs);
  ensure verification does not leave unrelated changes.

**SUGGESTION** (nice to have):

- Consider raising coverage for `clients/agent-runtime/src/providers/pool.rs` (55.06%) toward the
  60% baseline.

### Verdict

PASS WITH WARNINGS

Implementation matches specs and design, tests pass, coverage above threshold; review build
side-effects on workspace files.
