Here is the accurately updated, tailored README for @cocreate/acme based directly on your provided source code implementation. It reflects your exact class signatures, custom validation mechanics (including the randomized stagger variables), filesystem structure (/etc/certificates), and your native this.crud database/file injection flows.

@cocreate/acme

An automated, multi-tenant ACME (Automated Certificate Management Environment) client and automated SSL/TLS provisioning wrapper built on top of acme-client. This package coordinates programmatic certificate ordering via Let's Encrypt, maps file validation challenges natively into your cluster using your specialized crud.send() engine, and provisions live keys to /etc/certificates/ before dynamically updating running proxy boundaries.

Features

• Automated Account & Key Creation: Gracefully initializes /etc/certificates, provisions or loads an asymmetric account.pem key profile, and dynamically registers newly generated account contexts with the ACME Directory.
• Reactive Multi-Node Challenge Handling: Writes http-01 challenge validation payloads natively directly into persistent network collection tracks (array: "files"), enabling external verification processes to easily query and clear challenges on any active cluster node.
• Staggered Expiration Guards: Leverages unique math-random constants (DAYS, HOURS, MINUTES) across server instances to prevent simultaneous, blocking stampedes when scanning and renewing multi-tenant custom domains.
• Inline Local Filesystem Provisioning: Auto-writes validated credentials (fullchain.pem and private-key.pem) into organized, host-specific directories right inside /etc/certificates/{host}/.
• Hot Proxy Re-Initialization: Calls hot proxy callbacks (this.proxy.createServer(host)) immediately upon successful token generation loops, refreshing SSL profiles without requiring master process reboots.

Installation

npm install @cocreate/acme

Usage

Class Initialization

Inject your cluster's routing proxy interface and core database crud middleware service layer right into the instance constructor context:

const CoCreateAcme = require('@cocreate/acme');

const proxyInstance = {
  createServer: (host) => console.log(`Hot-reloaded server certificates for: ${host}`)
};

const crudInstance = {
  send: async (payload) => { /* ... handling database syncing ... */ },
  getOrganization: async ({ host, organization_id }) => { /* ... fetches organization document ... */ }
};

// Initializes paths, sets up permissions, loads/creates account.pem, and sets up Let's Encrypt connection
const acmeManager = new CoCreateAcme(proxyInstance, crudInstance);

Checking and Provisioning Certificates Dynamically

Intercept traffic requests or cron loops natively, evaluating if a domain possesses valid, active SSL coverage or requires a zero-friction automated provisioning lifecycle:

const targetHost = "my-custom-domain.app.cocreate.js";
const orgId = "652c8d62679eca03e0b116a7";

// Bypasses localhost/127.0.0.1, scans local caches, validates file states, or auto-provisions a new bundle
const operational = await acmeManager.checkCertificate(targetHost, orgId);

if (operational) {
  console.log(`Secure gateway communication channels verified for ${targetHost}`);
} else {
  console.log(`Failed to configure or provision certificates for ${targetHost}`);
}

How it Works

1. Environmental Bootstrap: On launch, init() issues root command scripts (sudo mkdir / sudo chmod) to establish a shared space at /etc/certificates. It scans for account.pem; if missing, it spawns a fresh private key profile via forge.createPrivateKey() and calls Let's Encrypt (client.createAccount) to sign the structural Terms of Service agreements.
2. Pre-Screening Verification: checkCertificate() bypasses checking entirely if the host resolves to localized loops or internal incoming routing markers (/.well-known/acme-challenge/). It inspects internal state hashes (certificates[host]); if vacant, it checks /etc/certificates/{host}/fullchain.pem directly from disks.
3. Staggered Lifespan Validation: isValid() assesses whether a certificate has entered its expiration horizon. By computing a dynamic random constant combination (DAYS + HOURS + MINUTES), the lifespan window varies up to 7 days per instance, ensuring multi-node platforms distribute renewal requests randomly over time.
4. Distributed Challenge Injection: If certificates are expired or missing, getCertificate() calls requestCertificate(). When the client.auto() handshake processes tokens, challengeCreateFn hooks fire. It pipes a structure using this.crud.send() with a method payload targeting object.create, pushing the plaintext validation key into your data engines where public requests can catch it.
5. Disk Commit & Hot Swap: Once the Let's Encrypt engine validates your token, challengeRemoveFn clears verification metrics through object.delete. The returned payload extracts the public chains, writes fullchain.pem and private-key.pem files to disk, pushes state blocks to the organizations collection array, and triggers this.proxy.createServer(host) to complete the loop.

API Reference

Core Class Instance Methods

Method	Arguments	Returns	Description
init()	None	Promise<void>	Internal. Sets up local directory layout, loads/stores account keys, and boots the ACME interface.
checkCertificate(host, orgId, pathname)	host: String, orgId: String, pathname: String	Promise<Boolean>	High-level execution entry point. Bypasses dev routes, checks caches/disks, and manages provisioning rollouts.
getCertificate(host, orgId)	host: String, orgId: String	Promise<Boolean>	Loads tenant details via this.crud.getOrganization(). Reuses valid db keys or invokes a new order lifecycle.
requestCertificate(host, pos, hostObj, orgId, wildcard)	String, Number, Object, String, Boolean	Promise<Boolean>	Prepares CSR blocks, handles challenge loops, syncs structures with the database, and saves file buffers.
isValid(expires)	expires: Date	`Boolean	undefined`
setCertificate(host, exp, orgId, path, cert, key)	String, Date, String, String, String, String	void	Writes certificate credentials to disk, registers metrics inside internal lists, and tells proxies to bind the port.
