## 一、 核心背景与铁律约束提示（供顾问审阅对照）
|
||
|
||
1. **求职画像契合（Senior 全栈/DevOps/AI 架构师）**：严禁流露“做生意的老板/小公司创始人”倾向；一切商业实战均转换为“生产系统架构、高可用交付与自动化运维”视角。
|
||
2. **纯洁人设与零禁用词**：绝对禁止 `homelab`, `home lab`, `家用`, `小主机`, `玩具`, `折腾`, `玩票` 等词汇。必须使用 `the infrastructure I manage`, `my self-hosted production nodes`, `production host`。
|
||
3. **第一人称单数**：统一使用单数 `I` / `我`，杜绝虚张声势的复数 `we`。
|
||
4. **数据绝对保真**：所有数字、性能比率、吞吐提升、故障现象严禁凭空捏造。
|
||
5. **OPSEC 安全脱敏**：无内部绝对路径（如 `D:/dev`），无真实私有内网 IP，公网 IP 必须转为文档保留地址。

## 二、 LinkedIn 拟发布动态文案
|
||
|
||
```text
|
||
In subscription and digital entitlement platforms, the core engineering challenge is never file storage — it is **state reconciliation**.
|
||
|
||
Manual provisioning or naive event triggers fail silently:
|
||
• A subscription expires, but a missed webhook leaves access active indefinitely.
|
||
• A payment webhook fires during server maintenance, locking a paying customer out of their files.
|
||
|
||
To guarantee zero-drift authorization, I architected a multi-tiered entitlement engine using n8n workflows, NocoDB, and private storage gateways.
|
||
|
||
The core principle: **Access is never an arbitrary flag; it is pure derived state.**
|
||
|
||
The system operates across five decoupled workflows:
|
||
1. Lifecycle Provisioning (W1): Listens for customer state updates, creating and toggling gateway accounts deterministically.
|
||
2. Product Grant Sync (W2): On confirmed purchase, computes the exact directory access paths matching the customer's active tier and updates gateway permissions.
|
||
3. Automated Expiry Sweeper (W3): A scheduled cron job running every 5 minutes evaluates timestamp boundaries and revokes expired path grants.
|
||
4. Continuous Reconciliation Loop (W4): Nightly at 03:00, a reconciliation engine computes the "ideal access state" directly from the database and audits it against the live storage gateway. Any discrepancy is automatically repaired and logged to telemetry.
|
||
5. Zero-Leak Public Verification (W5): Customer-facing portals verify purchase history via read-only token queries without exposing underlying database credentials.
|
||
|
||
By designing the system as a self-healing reconciliation loop (similar to Kubernetes controllers), temporary network drops or webhook hiccups are automatically corrected on the next cycle without human intervention.
|
||
|
||
Do your business authorization workflows rely on brittle one-off webhooks, or do you run automated reconciliation loops to catch state drift?
