Open Autonomous Intelligence Initiative

Depends on: OAII Base Model — Common Types v0.1; OAII Base Model — World v0.1.1; OAII Base Model — Event v0.1.1; OAII Base Model — Knowledge v0.1; OAII Base Model — Policy v0.1; OAII Base Model — Agent v0.1

1. Purpose

The Log object provides an explicit, structured, and privacy-aware record of system activity within a World. Logs enable auditability, accountability, debugging, and review without requiring continuous data retention or surveillance.

In the OAII Base Model, Logs are first-class objects designed to support trust, not monitoring.

---

2. Definition (Normative)

A Log is an abstract record object that:

• MUST be scoped to a specific World;
• MUST record references to actions, decisions, or lifecycle changes of other objects;
• MUST NOT require retention of raw Signals unless explicitly permitted by Policy;
• MUST support redaction, summarization, and aging;
• MUST be inspectable and exportable subject to privacy constraints.

A Log is not a data lake, surveillance archive, or implicit telemetry stream.

---

3. Scope and Non‑Scope

In Scope:

• Event lifecycle transitions
• Policy evaluations and enforcement outcomes
• Agent decisions and actions
• Knowledge creation and revision
• Device and Sensor health state changes

Out of Scope:

• Continuous raw sensor recording
• Undifferentiated telemetry dumps
• Behavioral profiling archives
• Cross‑World aggregation without mediation

---

4. Core Responsibilities

The Log object:

• Provides traceability across Events, Knowledge, Policies, and Agents;
• Supports accountability through explicit references and timestamps;
• Respects privacy by defaulting to references and summaries;
• Enables review by humans or systems without exposing raw data;
• Supports lifecycle management (retention, redaction, deletion).

---

5. Required Attributes (Abstract)

A conforming Log MUST expose the following attributes using shared types from Common Types v0.1.

5.1 Identity and Context

• log_id : LogId
• world_ref : WorldId

5.2 Log Classification

• log_type : string
  Examples: event_log, policy_log, agent_log, system_log, audit_log.

5.3 Temporal Reference

• temporal_extent : ParameterSet
  Time or interval covered by the Log entry or segment.

5.4 Referenced Objects

• object_refs : string[1..N]
  References to Events, Knowledge, Policies, Agents, Devices, or Sensors.

5.5 Content Representation

• log_payload : ParameterSet
  Structured summary or metadata (not raw Signals by default).

5.6 Privacy and Access

• privacy_class : PrivacyClass
• access_class : AccessClass

---

6. Log States (Normative)

A Log MUST support at least the following states:

• ACTIVE: accepting new entries
• SEALED: closed to modification
• REDACTED: content reduced per Policy
• ARCHIVED: retained but not active
• DELETED: removed per Policy

State transitions MUST be explicit and recorded.

---

7. Log Mechanism Bundle

Log creation, sealing, and redaction MUST be represented using a mechanism bundle:

• log_mechanism_id : MechanismId
• log_mechanism_params : ParameterSet
• log_mechanism_result : ResultSet (optional)

This bundle documents how logging behavior is implemented without mandating a storage technology.

---

8. Relationships to Other Objects

• World scopes Log meaning and retention
• Events generate lifecycle entries
• Policies govern what is logged and retained
• Agents generate decision and action records
• Knowledge revisions are logged for continuity
• Devices/Sensors may emit health or status logs

Logs MUST NOT be used to bypass Policy restrictions.

---

9. Methods (Normative, Abstract)

To standardize behavior, a conforming Log SHOULD support the following abstract methods:

9.1 append_entry

• method_params : ParameterSet (object refs, summary payload)
• method_result : ResultSet

9.2 seal_log

• method_params : ParameterSet
• method_result : ResultSet

9.3 redact_log

• method_params : ParameterSet (redaction rules)
• method_result : ResultSet

9.4 export_log

• method_params : ParameterSet (scope, format)
• method_result : ResultSet

Export MUST respect privacy_class and access_class constraints.

---

10. Edge‑Primary Constraints

In Edge‑primary systems, Logs:

• MUST be storable locally;
• SHOULD support bounded size and rotation;
• MAY export summaries rather than full logs;
• MUST continue functioning during network outages.

---

11. Failure and Degradation Modes

Log degradation may include:

• storage exhaustion
• partial corruption
• forced redaction due to policy change

Systems MUST prefer data minimization over unsafe retention.

---

12. Notes for Implementers (Non‑Normative)

• Logs should reference objects by ID rather than duplicate content.
• Audit logs may require stronger immutability guarantees than operational logs.
• For aging‑in‑place, logs should prioritize explainability over completeness.
