The clean, paste-ready Discussion text is in the copy-ready community submission. The submission draft retains its internal posting checklist.

Scope

• Authorized search and todo drafts only; no messages, task creation, media download, MCP adapter, hosted control plane, or archive export.
• The DSH plugin exports native name / apply and exposes only search and draftTodos. It never ingests, decrypts, or stores WeCom archives.
• The customer deployment keeps all WeCom credentials, RSA private keys, plaintext, and encryption keys. The official Finance SDK is a local sidecar dependency and is not redistributed here.

Controls

• Employee: participating archived conversations only.
• Manager: active permitted-team grant only.
• Compliance admin: active departmental grant and an audit reason.
• External conversation: server-side effective-consent lookup required.
• AES-256-GCM encrypted message payloads, versioned data keys, cursor-safe sync, and HMAC-linked audit events.

Read architecture, threat model, and deployment before deploying.

Installation and usage

The source repository is public, but the plugin is not yet published to a package registry. Install it from a source checkout in the customer-controlled deployment environment. It requires Node 22.19+, Corepack/pnpm, PostgreSQL, and a customer-local WeCom SDK sidecar.

git clone https://github.com/kenny245/dsh-wecom-plugin.git
cd dsh-wecom-plugin
corepack enable
pnpm install --frozen-lockfile
psql "$DATABASE_URL" -f infra/postgres/migrations/001_initial.sql
cp .env.example .env
pnpm run check
pnpm --filter @omdsh/wecom-archive-service start

Never put real secrets in .env.example, Docker Compose, committed config, or issues.

Cordis wiring

import wecomArchive from '@omdsh/dsh-wecom-plugin'

ctx.plugin(wecomArchive, {
  serviceUrl: 'https://archive.internal.example',
  audience: 'dsh-wecom-archive',
  timeoutMs: 3000,
  serviceToken: process.env.DSH_WECOM_PLUGIN_TOKEN!
})

The backend resolves the actor identity from the token; request payloads cannot select a role.

After starting the archive service, use the configured plugin command or its exposed search/todo-draft operation. A todo draft is only a review artifact: the MVP never sends a message, creates a task, or changes WeCom.

Risks, limitations, and compatibility

• This is a pre-publication MVP for compliant WeCom Conversation Content Archive deployments, not unrestricted employee visibility. Customers remain responsible for their archive entitlement, consent, retention, and access policy.
• External conversations are searchable only when the configured consent resolver reports effective archive consent. Missing or incorrect consent data fails explicitly; it does not expand access.
• The service performs a bounded PostgreSQL candidate scan after authorization. It is intentionally conservative but needs additional indexing before use with unbounded archive volumes.
• Attachments/media, automatic task creation, automatic message sending, managed hosting, and MCP are outside the MVP. Todo drafts require human verification.
• Compatibility target: Node.js >=22.19.0, pnpm >=11.19.0, PostgreSQL, a compatible DeepSeek Harness/Cordis host, and a customer-supplied compatible WeCom archive SDK sidecar. DSH/Cordis and SDK API changes may require updates.
