[Weekly Update] Fiber Link (Milestone 3) / 周报(里程碑 3)
Quick update for this week:
We continued operating Fiber Link’s long-term public demo on Testnet, and the overall environment remains stable with all core services running normally.
As of now, the demo has accumulated:
109 successful tips
32 successful withdrawals
1 channel rotation used to replenish withdrawal liquidity
Some representative samples and evidence are collected here:

## Fiber Link testnet public demo status
This week, we continued operating the … long-running public demo of Fiber Link on Nervos testnet, and the overall environment remains stable with all core services running normally.
As of now, the demo has accumulated:
- 109 successful tips
- 32 successful withdrawals
- 1 channel rotation used to replenish withdrawal liquidity
Some representative samples and evidence are collected in this issue.

### Channel rotation evidence
A live testnet run also verified the liquidity fallback path under hot-wallet underfunding.
| Item | Evidence |
| --- | --- |
| Withdrawal id | `b458d5b9-5c81-4c4e-bad5-e42cf4b08ecf` |
| Liquidity request id | `1b91c604-139a-4b56-9b56-ba80a94356d2` |
| Initial state | `LIQUIDITY_PENDING` (`hot wallet underfunded`) |
| Recovery strategy | `CHANNEL_ROTATION` |
| Legacy channel closed | `0x55190aa5eef6300b070e08d350161c857166a55600e379ad433f198266101085` |

This confirms the full path:
`hot wallet underfunded -> LIQUIDITY_PENDING -> CHANNEL_ROTATION -> legacy channel close -> withdrawal COMPLETED`
## Operations handoff preparation
At the same time, we are preparing a more operator-friendly deployment and plugin installation guide to support future handoff and independent operation:
- PR #329: https://github.com/Keith-CY/fiber-link/pull/329
At the same time, we are also preparing a more operator-friendly deployment and plugin installation guide to support future handoff and independent operation:
main ← docs/coolify-deployment-runbook
opened 04:18AM - 16 Apr 26 UTC
## Summary
- add a dedicated operator runbook for deploying Fiber Link/FNN on Co… olify
- capture the prior deployment lessons learned as actionable deployment guidance and known pitfalls
- link the new Coolify runbook from the docs index
## What changed
- added `docs/runbooks/coolify-deployment.md`
- documented staged bring-up order: DNS/ingress -> Fiber Link stack -> cross-service verification -> Discourse/plugin integration
- documented known pitfalls from prior real deployment attempts, including:
- DNS / ingress readiness confusion
- service-to-service wiring failures inside Coolify
- Discourse/plugin integration as a separate debugging surface
- fallback guidance to direct Docker for Discourse if Coolify adds too much friction
- post-deploy automation / withdrawal readiness caveats
- added the runbook link to `docs/README.md`
## Validation
- `git diff --check`
- docs-only change; runtime metrics: `N/A` (no executable code paths changed)
Closes #327
