  "comment": "## Triage Summary\n\n**Severity:** Critical (panic / 500 error)  \n**Category:** Bug  \n**Labels:** `area:api`, `area:data`, `priority:critical`, `type:bug`\n\n### Problem\nThe `ListUsers` handler panics when PostgreSQL is unreachable, producing a 500 Internal Server Error instead of a graceful 503 response.\n\n### Root Cause Hypothesis\nThe handler at `handlers/users.go:25` likely does not check the error returned from the database query. When the connection is down, this results in a nil pointer dereference or unhandled error that triggers a panic.\n\n### Recommended Fix\n- Add proper error handling in `ListUsers` to detect database connectivity failures and return **503 Service Unavailable** with a descriptive error message.\n- Consider adding panic-recovery middleware as a safety net for all handlers.\n\n### Proposed Test Case\n\n```\nTest: ListUsers returns 503 when database is unreachable\n\nSetup:\n  - Configure the handler with a database connection that is\n    unavailable (mock or point to a stopped instance).\n\nSteps:\n  1. Send GET /users to the handler.\n  2. Assert response status is 503 Service Unavailable.\n  3. Assert response body contains a meaningful error message.\n  4. Assert no panic occurred (process stays up).\n\nEdge cases:\n  - Connection drops mid-query (partial failure).\n  - Normal 200 response when DB is healthy (regression guard).\n```\n\nThis issue has clear reproduction steps and sufficient detail to begin investigation."
