<a href=#13 id=13 data-nosnippet>13</a>/// # Definition
|
||||
<a href=#14 id=14 data-nosnippet>14</a>/// `Message` is a data structure that models a single mail exchange between two peers.
|
||||
<a href=#15 id=15 data-nosnippet>15</a>/// It contains a unique identifier, sender and recipient identifiers, a topic string, a JSON payload,
|
||||
<a href=#16 id=16 data-nosnippet>16</a>/// and timestamps for when the message was sent and optionally when it was read.
|
||||
<a href=#17 id=17 data-nosnippet>17</a>///
|
||||
<a href=#18 id=18 data-nosnippet>18</a>/// # Implementation Details
|
||||
<a href=#19 id=19 data-nosnippet>19</a>/// - `id` is a **Uuid** generated by the caller to guarantee global uniqueness.
|
||||
<a href=#20 id=20 data-nosnippet>20</a>/// - `payload` uses `serde_json::Value` so arbitrary JSON can be attached to the message.
|
||||
<a href=#21 id=21 data-nosnippet>21</a>/// - `sent_at` and `read_at` are stored as `chrono::DateTime<Utc>` to provide timezone‑agnostic timestamps.
|
||||
<a href=#22 id=22 data-nosnippet>22</a>///
|
||||
<a href=#23 id=23 data-nosnippet>23</a>/// # Rationale
|
||||
<a href=#24 id=24 data-nosnippet>24</a>/// This struct provides a lightweight, serialisable representation of a message that can be persisted
|
||||
<a href=#25 id=25 data-nosnippet>25</a>/// in the SQLite‑backed mailbox (see `Mailbox`). Keeping the payload as JSON allows different subsystems
|
||||
<a href=#26 id=26 data-nosnippet>26</a>/// of the CHORUS platform to embed domain‑specific data without requiring a rigid schema.

<a href=#2 id=2 data-nosnippet>2</a>//!
|

<a href=#3 id=3 data-nosnippet>3</a>//! **Intelligence Crate** – Provides the *curation* layer for the CHORUS system.
|
||||
<a href=#4 id=4 data-nosnippet>4</a>//!
|
||||
<a href=#5 id=5 data-nosnippet>5</a>//! The purpose of this crate is to take **Decision Records** generated by autonomous
|
||||
<a href=#6 id=6 data-nosnippet>6</a>//! agents, validate them, and persist them into the graph database. It isolates the
|
||||
<a href=#7 id=7 data-nosnippet>7</a>//! validation and storage concerns so that other components (e.g. provenance, security)
|
||||
<a href=#8 id=8 data-nosnippet>8</a>//! can work with a clean, audited data model.
|
||||
<a href=#9 id=9 data-nosnippet>9</a>//!
|

<a href=#10 id=10 data-nosnippet>10</a>//! ## Architectural Rationale
|
||||
<a href=#11 id=11 data-nosnippet>11</a>//!
|
||||
<a href=#12 id=12 data-nosnippet>12</a>//! * **Separation of concerns** – Agents produce raw decisions; this crate is the
|
||||
<a href=#13 id=13 data-nosnippet>13</a>//! single source of truth for how those decisions are stored.
|
||||
<a href=#14 id=14 data-nosnippet>14</a>//! * **Auditability** – By persisting to a Dolt‑backed graph each decision is versioned
|
||||
<a href=#15 id=15 data-nosnippet>15</a>//! and can be replay‑backed, satisfying CHORUS’s requirement for reproducible
|
||||
<a href=#16 id=16 data-nosnippet>16</a>//! reasoning.
|
||||
<a href=#17 id=17 data-nosnippet>17</a>//! * **Extensibility** – The `CurationEngine` can be extended with additional validation
|
||||
<a href=#18 id=18 data-nosnippet>18</a>//! steps (e.g. policy checks) without touching the agents themselves.
|
||||
<a href=#19 id=19 data-nosnippet>19</a>//!
|
||||
<a href=#20 id=20 data-nosnippet>20</a>//! The crate depends on:
|
||||
<a href=#21 id=21 data-nosnippet>21</a>//! * `chrs-graph` – a thin wrapper around a Dolt‑backed graph implementation.
|
||||
<a href=#22 id=22 data-nosnippet>22</a>//! * `ucxl` – for addressing external knowledge artefacts.
|
||||
<a href=#23 id=23 data-nosnippet>23</a>//! * `chrono`, `serde`, `uuid` – standard utilities for timestamps, (de)serialization
|
||||
<a href=#24 id=24 data-nosnippet>24</a>//! and unique identifiers.
|
||||
<a href=#25 id=25 data-nosnippet>25</a>//!
