## Deviations

!!! note
    Compliance is driven entirely by evaluations reported through `PutEvaluations` and
    `PutExternalEvaluation` — Floci does not record resource configurations or run rule
    evaluations itself. Until an evaluation is reported, compliance returns
    `INSUFFICIENT_DATA`.

    - **ResultToken**: real AWS hands custom rules an opaque token inside the evaluation
      event. Floci has no evaluation event, so `PutEvaluations` expects the config rule
      name as the token (a `<rule-name>:<suffix>` form is also accepted).
    - `StartConfigRulesEvaluation` marks the rule as invoked but does not call the rule's
      Lambda function.
    - `FirstActivatedTime` and invocation timestamps are runtime state and are not
      persisted across restarts.
    - `DescribeConfigRules` and `DescribeComplianceByConfigRule` use a fixed page size
      of 25.
    - Configuration recorders and delivery channels are stored and validated, but no
      configuration items or snapshots are produced.
    - Conformance pack status is always `CREATE_SUCCESSFUL`; pack templates are stored,
      not evaluated.
    - `PutAggregationAuthorization` records the authorization and returns its ARN, but no
      data is aggregated: configuration aggregators are not emulated.
      `DeleteAggregationAuthorization` on an authorization that does not exist succeeds,
      because the Config API models no "not found" error for that operation.
