# Enodia Sentinel JSON Schemas
|
|
|
|
Applies to package version: `0.7.0`
|
|
Docs version: `0.7`
|
|
Schema generation: `v1`
|
|
|
|
Sentinel uses stable schema IDs for operator-facing JSON contracts. These IDs
|
|
are lightweight compatibility markers, not external JSON Schema files. The v1
|
|
rule is additive: future releases may add fields, but required v1 fields should
|
|
not be removed, renamed, or change type.
|
|
|
|
Schema IDs live in `enodia_sentinel/schemas.py`, and compatibility tests in
|
|
`tests/test_schema_contracts.py` pin the required v1 fields.
|
|
|
|
## `enodia.alert.v1`
|
|
|
|
Single detection object, used inside alert snapshots and by commands such as
|
|
`posture check --json`.
|
|
|
|
Required fields:
|
|
|
|
| Field | Type | Meaning |
|
|
|---|---|---|
|
|
| `sid` | integer | Stable signature/rule id. |
|
|
| `severity` | string | `MEDIUM`, `HIGH`, or `CRITICAL`. |
|
|
| `signature` | string | Stable machine-readable detection name. |
|
|
| `classtype` | string | Snort/Suricata-style category. |
|
|
| `key` | string | Cooldown/dedup identity. |
|
|
| `detail` | string | Human-readable finding detail. |
|
|
| `pids` | array | Process IDs tied to the finding. |
|
|
|
|
## `enodia.alert.snapshot.v1`
|
|
|
|
Structured alert sidecar written beside each text snapshot under `log_dir`.
|
|
|

Required fields:
|
|
|
|
| Field | Type | Meaning |
|
|
|---|---|---|

|
|
|
|
## `enodia.incident.v1`
