# Overview and Getting Started

## Purpose and Scope

`telecom-mas-agent` is a small Node.js package that exposes a single class, `TelecomMASAgent`, which simulates a multi-agent telecommunications workflow entirely in memory. The package is distributed via npm and targets Node.js 14 and above, as indicated by the project badges and the `main` entry in `package.json` described in [README.md](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/README.md).

The agent is designed to demonstrate a basic telecom operations model: tracking per-user call balances, recording simulated phone calls that deduct minutes, logging outgoing SMS messages, and storing push notifications destined for specific users. All operations are asynchronous (`Promise`-based) and use an internal `_simulateDelay()` helper to mimic network latency rather than calling any real carrier or telco API. Source: [index.js:6-7]() and [index.js:113-115]().

> **Note on documentation accuracy.** The README markets the package with terms such as "AI-powered," "conversational intelligence," and "military-grade security." None of these capabilities are implemented in `index.js`; the codebase is a simulation that runs entirely in memory with no external dependencies. The wiki describes the package as it actually behaves in code.

## Architecture and Internal State

The `TelecomMASAgent` class is a single-file module exported via `module.exports = TelecomMASAgent;` at the end of [index.js:117](). It keeps three in-memory data structures:

| Field | Type | Purpose |
|---|---|---|
| `agentName` | `string` | Human-readable name used in `introduce()` and self-identification. |
| `userBalances` | `Map<string, number>` | Per-user call balance in minutes. |
| `sentMessages` | `Array<Object>` | Append-only SMS log; each entry stores `to`, `message`, and ISO `timestamp`. |
| `pushNotifications` | `Array<Object>` | Append-only push log; each entry stores `userId`, `notification`, and ISO `timestamp`. |

Source: [index.js:4-7]() and [index.js:46-49]().

Because state is held only in memory, restarting the Node.js process resets all balances, messages, and notifications. This is a deliberate design choice for a simulation package and is consistent with the "Zero Dependencies" claim in the README.

### Method Groups

The class exposes four functional groups, all of which are described in the API Reference section of [README.md](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/README.md):

    D --> D1[sendSMS]
    D --> D2[getSentMessages]
    E --> E1[sendPushNotification]
    E --> E2[getPushNotifications]
```

Each mutating method validates its input and either returns a `Promise<string>` confirmation or throws an `Error` for unknown users and insufficient balances. Source: [index.js:24-26](), [index.js:43-46](), and [index.js:68-70]().

## Installation

The package is installed from npm the same way as any other Node module:

```bash
npm install telecom-mas-agent
```

This installation method, the supported Node.js version, and the standard `npm test` workflow are documented in the "Installation" and "Development" sections of [README.md](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/README.md). The project structure described there is minimal:

```
telecom-mas-agent/
├── index.js          # Main agent class
├── package.json      # Package configuration
├── README.md         # Documentation
└── __tests__/        # Test files
    └── index.test.js
```

Source: [README.md:Project Structure section]().

## Quick Start

The following snippet is the minimum viable usage, taken from the "AI-Powered Quick Start" example in the README and adapted to match the actual method signatures in [index.js](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js):

```javascript
const TelecomMASAgent = require('telecom-mas-agent');

const agent = new TelecomMASAgent('My Telco Agent');

(async () => {
  await agent.initializeUser('user_001', 500);             // 500 minutes
  console.log(await agent.checkCallBalance('user_001'));  // remaining balance
  console.log(await agent.makeCall('user_001', 30));       // deduct 30 minutes
  console.log(await agent.sendSMS('+1-555-0100', 'Hi!'));  // logged
  console.log(await agent.sendPushNotification('user_001', 'Welcome!'));

  console.log(agent.getSentMessages());                    // SMS log
  console.log(agent.getPushNotifications('user_001'));    // notifications for user
  console.log(agent.introduce());                          // self-description
})();
```

Key behavioral points to be aware of, derived directly from the source:

- `initializeUser()` overwrites any existing balance for a given `userId` (the implementation uses `Map.set`). Source: [index.js:18-19]().
- `checkCallBalance()` and `makeCall()` both throw `Error('User <id> not found.')` when the user has not been initialized. Source: [index.js:24-26]() and [index.js:43-45]().
- `makeCall()` throws `Error('Insufficient balance for user <id>.')` if the requested minutes exceed the current balance. Source: [index.js:46-49]().
- `sendSMS()` does not validate phone number format; it only stores the entry. Source: [index.js:55-58]().
- `getSentMessages()` returns the global log (no per-user filtering), while `getPushNotifications(userId)` filters by user. Source: [index.js:63-65]() and [index.js:78-80]().

## Common Failure Modes

When integrating the agent into a host application, the following failure modes are the most likely:

1. **User not initialized.** Calling `checkCallBalance`, `makeCall`, or `getPushNotifications` before `initializeUser` causes a thrown `Error`. Always initialize users first.
2. **Negative or non-numeric minutes.** `makeCall` does not validate that `minutes` is positive; passing a value larger than the balance triggers the "Insufficient balance" error, and passing a non-number causes a silent `NaN` balance. Source: [index.js:43-49]().
3. **State loss on restart.** Because balances and logs are in-memory only, a process restart wipes all data. This is expected for a simulation but should not be relied on for production use.
4. **No concurrency control.** `makeCall` performs a read-then-write on `userBalances` without locking; concurrent calls for the same user can race. Source: [index.js:43-50]().

# API Reference

## Overview

The `telecom-mas-agent` package exposes a single public class, `TelecomMASAgent`, defined in [index.js:1-15](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js). The class is a self-contained, promise-based simulation of a telecom multi-agent system. It manages user call balances, dispatches SMS messages, and records push notifications entirely in memory. There are no external dependencies, and every long-running method is implemented as an `async` function that resolves with a human-readable confirmation string.

The class keeps state in three internal structures: a `Map` for user balances and two arrays for SMS and push notification logs. The class is exported as the module's default export through `module.exports = TelecomMASAgent;` at the bottom of the file.

Source: [index.js:1-15]()

## Class Architecture

The diagram below shows the public surface of the `TelecomMASAgent` class and the relationships between its three internal stores.

```mermaid
classDiagram
    class TelecomMASAgent {
        +string agentName
        +Map userBalances
        +Array sentMessages
        +Array pushNotifications
        +constructor(agentName)
        +initializeUser(userId, initialBalance)
        +checkCallBalance(userId)
        +makeCall(userId, minutes)
        +sendSMS(toNumber, message)
        +getSentMessages()
        +sendPushNotification(userId, notification)
        +getPushNotifications(userId)
        +introduce()
        -_simulateDelay(ms)
    }
```

Source: [index.js:1-15]()

## Constructor

#### `new TelecomMASAgent(agentName?)`

Creates a new agent instance and initializes the three internal stores. The single parameter is optional; when omitted, the agent is named `"Telecom MAS Agent"`.

```javascript
const TelecomMASAgent = require('telecom-mas-agent');
const agent = new TelecomMASAgent("My Telecom Agent");
```

Source: [index.js:3-8]()

## User Management

#### `initializeUser(userId, initialBalance?)`

Registers a user and seeds their call balance in minutes. The default initial balance is 100 minutes. The method waits 500 ms via `_simulateDelay` and resolves with a confirmation string. It does not throw and silently overwrites an existing user's balance if called twice for the same `userId`.

Source: [index.js:17-26]()

#### `checkCallBalance(userId)`

Returns a human-readable string with the current balance after a 300 ms simulated delay. Throws `Error("User <id> not found.")` when the user has not been initialized.

Source: [index.js:28-38]()

## Call Operations

#### `makeCall(userId, minutes)`

Deducts `minutes` from the user's balance and returns a confirmation string with the new balance. Throws `Error("User <id> not found.")` if the user is unknown, and `Error("Insufficient balance for user <id>.")` if the requested minutes exceed the current balance. The method does not explicitly validate that `minutes` is positive, so callers should sanitize input themselves.

Source: [index.js:40-60]()

## SMS Operations

#### `sendSMS(toNumber, message)`

Pushes a `{ to, message, timestamp }` record into `sentMessages` and returns a confirmation string after a 200 ms delay. The method does not validate the phone number or message content; it always succeeds.

Source: [index.js:62-72]()

#### `getSentMessages()`

Returns the internal `sentMessages` array directly. Each entry has the shape:

```javascript
{
  to: "+1234567890",
  message: "Hello!",
  timestamp: "2025-12-08T10:30:00.000Z"
}
```

Because the live reference is returned, downstream code can mutate the agent's log; treat the result as read-only.

Source: [index.js:74-80]()

## Push Notifications

#### `sendPushNotification(userId, notification)`

Records a push notification for the given user and returns a confirmation string after a 300 ms delay. It does not verify that the user has been initialized.

Source: [index.js:82-92]()

#### `getPushNotifications(userId)`

Filters the internal `pushNotifications` array and returns only entries whose `userId` matches the argument. Returns an empty array when no notifications exist for that user.

Source: [index.js:94-100]()

## Utility Methods

#### `introduce()`

Returns a greeting string that includes the configured `agentName`. Useful as a smoke test that the module is loaded correctly.

```javascript
agent.introduce();
// "Hello! I am My Telecom Agent, your telecom multi-agent system. How can I assist you today?"
```

Source: [index.js:102-108]()

## API Method Summary

The table below summarizes every public method, its parameters, return type, and error behavior. All entries are taken directly from the implementation in [index.js](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js).

| Method | Parameters | Returns | Throws |
| --- | --- | --- | --- |
| `constructor` | `agentName?` (string, default `"Telecom MAS Agent"`) | instance | — |
| `initializeUser` | `userId` (string), `initialBalance?` (number, default 100) | `Promise<string>` | — |
| `checkCallBalance` | `userId` (string) | `Promise<string>` | user not found |
| `makeCall` | `userId` (string), `minutes` (number) | `Promise<string>` | user not found, insufficient balance |
| `sendSMS` | `toNumber` (string), `message` (string) | `Promise<string>` | — |
| `getSentMessages` | — | `Array<Object>` | — |
| `sendPushNotification` | `userId` (string), `notification` (string) | `Promise<string>` | — |
| `getPushNotifications` | `userId` (string) | `Array<Object>` | — |
| `introduce` | — | `string` | — |

Source: [index.js:3-108](), [README.md:1-200]()

## Usage Notes and Failure Modes

- **In-memory only.** Reloading the process clears all balances, sent messages, and notifications. There is no persistence layer wired into the class.
- **No input validation.** Only `checkCallBalance` and `makeCall` throw for unknown users, and only `makeCall` validates that the balance is sufficient. Phone numbers, message bodies, notification text, and `minutes` sign are otherwise accepted as-is.
- **Simulated latency.** Every async method calls `_simulateDelay`, a `setTimeout`-based helper at the bottom of [index.js:110-115](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js). This is appropriate for tests and demos but should be replaced before integrating with a real carrier.
- **README claim gap.** The [README.md](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/README.md) documents features such as "AES-256 encryption", "conversational AI", "sentiment analysis", and "zero-trust security". The implementation in [index.js](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js) does not contain any cryptography, ML integration, or outbound network calls. Treat those sections as marketing copy rather than API behavior.
- **Mutating returned arrays.** `getSentMessages` and `getPushNotifications` return references into internal arrays; downstream code that mutates them will alter the agent's state.

# Internal Architecture and Data Management

## Overview

The `TelecomMASAgent` class in [index.js](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js) is the single, monolithic implementation of the entire telecom multi-agent system. It manages three in-memory data stores, simulates asynchronous network operations with artificial latency, and exposes a small, promise-based API to consumers. Despite the project's branding as an "enterprise-grade AI-powered" platform described in [README.md](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/README.md), the runtime architecture is intentionally minimal: there is no database, no external dependency, and no actual carrier integration.

This page describes how the agent is constructed, how state is organized in memory, how data flows through the public methods, and the practical limitations a developer should be aware of when integrating or extending the package.

## Class Composition and State

`TelecomMASAgent` is defined as a single ES2015 class with a constructor that accepts an optional `agentName` and initializes three private data structures. Source: [index.js:3-7](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L3-L7)

| Field | Type | Purpose | Lifetime |
|---|---|---|---|
| `agentName` | `string` | Human-readable label used by `introduce()` | Per instance |
| `userBalances` | `Map<string, number>` | Tracks call-minute balance keyed by user ID | Per instance, in-memory |
| `sentMessages` | `Array<Object>` | Append-only SMS log | Per instance, in-memory |
| `pushNotifications` | `Array<Object>` | Append-only push-notification log | Per instance, in-memory |

Because all four fields are instance-scoped and reside on the JavaScript heap, every data store is destroyed when the process exits. There is no serialization layer, no disk persistence, and no inter-process sharing. Source: [index.js:3-7](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L3-L7)

## Operation Lifecycle and Asynchronous Pattern

Every mutating public method is declared `async` and waits for a private helper, `_simulateDelay(ms)`, before performing its work. The helper resolves a `setTimeout` promise and is used to mimic network round-trip latency rather than doing any real I/O. Source: [index.js:142-144](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L142-L144)

The fixed simulated delays per operation are:

- `initializeUser` — 500 ms. Source: [index.js:15](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L15)
- `checkCallBalance` — 300 ms. Source: [index.js:25](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L25)
- `makeCall` — 400 ms. Source: [index.js:43](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L43)
- `sendSMS` — 200 ms. Source: [index.js:60](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L60)
- `sendPushNotification` — 300 ms. Source: [index.js:77](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L77)

This pattern means callers must `await` results; the methods return `Promise<string>` for mutations and queries, and plain values for read-only helpers such as `getSentMessages()`, `getPushNotifications(userId)`, and `introduce()`. Source: [index.js:113-139](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L113-L139)

## Data Flow Across the Public API

The diagram below shows how a typical client call moves through the agent's in-memory stores. There are no branches, no concurrent workers, and no background agents — every operation is sequential within a single Node.js event loop.

```mermaid
flowchart LR
    Client[Caller / Consumer Code] -->|await| API[Public API Method]
    API --> Delay["_simulateDelay(ms)<br/>(setTimeout)"]
    Delay --> Logic[Validation + Mutation Logic]
    Logic --> Balance[(userBalances Map)]
    Logic --> SMS[(sentMessages Array)]
    Logic --> Push[(pushNotifications Array)]
    Balance -.read.-> API
    SMS -.read.-> API
    Push -.read.-> API
    API -->|Promise<string>| Client
```

Mutations write to the stores immediately after the simulated delay resolves. Reads return formatted strings (e.g., `"User enterprise_user_001 has 470 minutes remaining."`) or filtered array views. Source: [index.js:21-32](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L21-L32) and [index.js:113-116](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L113-L116)

## Validation Rules and Failure Modes

The agent enforces a small set of invariants and surfaces failures as thrown `Error` instances:

1. **Unknown user on `checkCallBalance`** — throws `Error("User <id> not found.")` if the ID is absent from `userBalances`. Source: [index.js:27-29](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L27-L29)
2. **Unknown user on `makeCall`** — same error as above before any deduction occurs. Source: [index.js:45-47](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L45-L47)
3. **Insufficient balance on `makeCall`** — throws `Error("Insufficient balance for user <id>.")` when `currentBalance < minutes`; the balance is not modified. Source: [index.js:48-51](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L48-L51)
4. **`sendSMS`** and **`sendPushNotification`** — perform no input validation beyond pushing the supplied payload verbatim into their respective arrays; an empty `message` or `notification` is accepted. Source: [index.js:59-63](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L59-L63) and [index.js:77-80](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L77-L80)

All other methods (`initializeUser`, `getSentMessages`, `getPushNotifications`, `introduce`) do not throw under any documented input.

## Practical Limitations

Several capabilities advertised in [README.md](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/README.md) — including "AES-256 encryption", "zero-trust architecture", "conversational AI", "predictive analytics", and "fraud detection" — are not implemented in [index.js](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js). The source contains no cryptographic primitives, no ML model calls, and no telemetry pipeline. The README is also internally duplicated and contains truncated code samples; treat it as marketing copy rather than authoritative behavior. Source: [index.js:1-146](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L1-L146) (entire file review).

Operationally, this means:

- **No concurrency safety**: concurrent `makeCall` calls for the same user can race because the read-check-write sequence inside `makeCall` is not atomic. Source: [index.js:43-54](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js#L43-L54)
- **No persistence**: restarting the Node process clears every user balance and message log.
- **No authentication or authorization**: any caller with a reference to the instance can mutate any user's balance.

# Usage Patterns, Workflows, and Failure Modes

## Overview and Scope

The `TelecomMASAgent` class ([index.js:3-8](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)) is a single-class, in-process simulator for telecom operations. Despite the README's marketing language around "AI-powered conversational intelligence," "machine learning," and "military-grade security," the implementation in [index.js](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js) is a stateful object built around three in-memory data structures:

- `userBalances: Map<string, number>` — per-user call minutes
- `sentMessages: Array<Object>` — accumulated SMS log entries
- `pushNotifications: Array<Object>` — accumulated push notification entries

All state is process-local. The class performs no I/O, no network calls, no authentication, and no encryption. Every mutating method resolves only after a `_simulateDelay()` ([index.js:79-81](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)) that wraps `setTimeout`, which is the only "async" behavior the code actually exhibits. Source: [index.js:79-81]()

This page is therefore about how callers are expected to *use* the simulator, what the realistic call sequences look like, and where the class will throw — not about features the README advertises but the source does not implement.

## Common Usage Patterns

### Basic Lifecycle

The Quick Start in the README and the constructor signature ([index.js:3-8](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)) describe a five-step lifecycle:

1. Construct an agent with an optional `agentName` (default `"Telecom MAS Agent"`).
2. `initializeUser(userId, initialBalance = 100)` to seed minutes ([index.js:10-16](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)).
3. `checkCallBalance(userId)` to read state ([index.js:18-27](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)).
4. `makeCall(userId, minutes)` to deduct minutes ([index.js:29-48](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)).
5. `sendSMS(toNumber, message)` and `sendPushNotification(userId, notification)` for messaging.

Every mutating method is `async` and returns a `Promise<string>`. Source: [index.js:10-48]()

### Conversational / Onboarding Workflow

The README's "AI-Powered Conversational Telecom Workflow" example wraps the agent in an external service class that performs onboarding, generates a welcome string, and stores derived "AI insights" in a side `Map`. The agent itself contributes no AI behavior: `introduce()` ([index.js:75-77](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)) returns a single static template of the form `Hello! I am ${this.agentName}, your telecom multi-agent system. How can I assist you today?`. The "workflow" is therefore a consumer-side composition pattern, not an agent capability. Source: [index.js:75-77]()

### Enterprise Integration Pattern

The README's "Enterprise Integration" example simply instantiates a second agent with a different name and a larger initial balance. There is no multi-agent coordination, no message bus, and no shared state in the source — multiple `TelecomMASAgent` instances are fully isolated, each owning its own `Map` and arrays ([index.js:5-7](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)). Source: [index.js:5-7]()

## Workflow State and Data Flow

```mermaid
sequenceDiagram
    participant C as Caller
    participant A as TelecomMASAgent
    participant S as In-Memory Stores
    C->>A: initializeUser(uid, bal)
    A->>S: userBalances.set(uid, bal)
    C->>A: checkCallBalance(uid)
    A-->>C: "User uid has N minutes remaining."
    C->>A: makeCall(uid, m)
    A->>S: userBalances.set(uid, N - m)
    C->>A: sendSMS(to, msg)
    A->>S: sentMessages.push({to, msg, ts})
    C->>A: sendPushNotification(uid, n)
    A->>S: pushNotifications.push({uid, n, ts})
    C->>A: getSentMessages() / getPushNotifications(uid)
    A-->>C: filtered array snapshot
```

The diagram reflects the actual call paths: each mutating call resolves only after `_simulateDelay` completes ([index.js:79-81](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)), and read methods operate synchronously on the in-memory arrays without simulated delay ([index.js:58-61](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js), [index.js:70-73](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)). Notably, `getSentMessages()` returns the global array with no filtering, whereas `getPushNotifications(userId)` filters by `userId` ([index.js:71-73](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)). Source: [index.js:58-73]()

## Failure Modes and Error Handling

The class throws `Error` objects in exactly three observable conditions:

| Method | Trigger | Thrown Message | Source |
|---|---|---|---|
| `checkCallBalance` | `userId` not in `userBalances` | `User ${userId} not found.` | [index.js:22-24](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js) |
| `makeCall` | `userId` not in `userBalances` | `User ${userId} not found.` | [index.js:43-45](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js) |
| `makeCall` | `currentBalance < minutes` | `Insufficient balance for user ${userId}.` | [index.js:46-48](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js) |

Behavioral notes derived directly from the source:

- **No internal try/catch.** All errors propagate as Promise rejections; callers must wrap invocations in `.catch()` or `try/await` blocks, as the README's Quick Start does. Source: [index.js:22-48]()
- **No input validation beyond existence checks.** Negative or non-numeric `minutes` are accepted by `makeCall` ([index.js:29-48](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)) and `initializeUser` ([index.js:10-16](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)), which can drive balances negative.
- **No transactionality.** A successful `makeCall` deducts minutes immediately; downstream SMS or push failures cannot roll back the deduction.
- **State is non-persistent.** Process restart wipes all balances, messages, and notifications — a consequence of using a `Map` and arrays ([index.js:5-7](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)) with no backing store.
- **No concurrency guard.** The check-then-set in `makeCall` ([index.js:46-50](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)) is not atomic; two concurrent calls can both pass the balance check before either write, allowing the balance to go negative.
- **Inconsistent read APIs.** `getSentMessages()` returns the global log ([index.js:58-61](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)), while `getPushNotifications(userId)` filters by user ([index.js:70-73](https://github.com/darshanbmehta/telecom-mas-agent/blob/main/index.js)). Callers needing per-recipient SMS history must filter client-side.
