Log reflection: authorization metadata and evidence reports

The App supplies authorized evidence sources; the reflection task produces a sourced report through ordinary model and tool contracts.

source checks the real identity and visible range for every query. The model reads evidence through history.query and then submits observed, hypothesis, or recommendation; observed must reference evidence IDs actually read in this run.

The report keeps incompleteness and missing explanations, and persisted defaults to false. Read permission, handing content to the model, and disclosing results are each decided by the App; the metadata adapter does not pass raw log body text.

Progressive examples for the same business case

Bind the reflection model, evidence source, and authorization

Beginner · Node.js

TypeScript

import { defineReflection } from '@jangts/agent-core/kits/reflection';
import type { ReflectionSource } from '@jangts/agent-core/kits/reflection';
import type { ModelRunner, OperationContext } from '@jangts/agent-core';

export function review<App>(model: ModelRunner, source: ReflectionSource<App>,
  authorize: (question: string, context: OperationContext<App>) => Promise<void>) {
  return defineReflection({ model, source, authorize,
    maxCalls: 4, reserveCalls: 1, maxPages: 4, maxEvents: 64, maxEvidenceChars: 12000 });
}

JavaScript

import { defineReflection } from '@jangts/agent-core/kits/reflection';
export function review(model, source, authorize) {
    return defineReflection({ model, source, authorize,
        maxCalls: 4, reserveCalls: 1, maxPages: 4, maxEvents: 64, maxEvidenceChars: 12000 });
}

Build the same kind of evidence source from a log reader

Configuration · Node.js

The reader's directory scope, shutdown, and retention are managed by the App. The adapted source can be passed into the same defineReflection.

TypeScript

import { defineReflectionLogSource } from '@jangts/agent-core/kits/reflection';
import type { ReflectionLogReader } from '@jangts/agent-core/kits/reflection';
import type { OperationContext } from '@jangts/agent-core';

export function logSource<App>(reader: ReflectionLogReader, traceId: string,
  authorize: (context: OperationContext<App>) => Promise<void>) {
  return defineReflectionLogSource({ reader, traceId, id: 'authorized-history', authorize });
}

JavaScript

import { defineReflectionLogSource } from '@jangts/agent-core/kits/reflection';
export function logSource(reader, traceId, authorize) {
    return defineReflectionLogSource({ reader, traceId, id: 'authorized-history', authorize });
}
