# 📒 Problem #15 ·Deployment‑Deadlock Problem Map
|
||
|
||
Some AI stacks *freeze in place* when two or more services depend on each
|
||
other’s side‑effects to finish booting:
|
||
|
||
* Vector DB waits for schema migration →
|
||
Migrator waits for DB “ready” flag (circular)
|
||
* RAG ingester waits for retriever endpoint →
|
||
Retriever waits for populated index (circular)
|
||
* Agent A publishes a topic that Agent B subscribes to —
|
||
but Agent B must ack before Agent A continues (stalemate)
|
||
|
||
WFGY resolves these **deployment deadlocks** with dependency graphs, semantic
|
||
ping chains, and BBCR timeouts that break the loop.
|
||

|
||
## 🚨 Classic Deadlock Loops
|
||
|
||
| Loop Pattern | Real‑World Fallout |
|
||
| --------------------------------------- | ---------------------------------------- |
|
||
| **DB ↔ Migrator** | Migrations never apply; API 502 forever |
|
||
| **Index Build ↔ Retriever health‑check** | Ingestion hangs; queries return 404 |
|
||
| **Agent A ↔ Agent B ack chain** | Task queue stalls; CPU idles at 0 % |
|
||
| **Secrets Store ↔ App init** | Containers restart endlessly |

## 🛡️ WFGY Deadlock Breakers
|
||
|
||
| Loop Pattern | Guard Module | Remedy | Status |
|
||
| ------------------------- | ----------------------- | ---------------------------------------- | ------ |
|
||
| DB–Migrator | **Dependency Graph** | Topo‑sort tasks; migrator forced first | ✅ Stable |
|
||
| Index–Retriever | **Ping Chain** | Synthetic “warm” doc until real ingest | ⚠️ Beta |
|
||
| Agent ack loop | **BBCR Timeout** | Auto‑abort & replay with back‑off | ✅ Stable |
|
||
| Secrets race | **Boot Checkpoint** | Wait‑on‑secret with exponential delay | 🛠 Planned |
|
||
|

|
||
|
||
## 📝 How It Works
|
||
|
||
1. **Dependency Graph**
|
||
Services declare `needs:` edges in `wgfy.yaml`.
|
||
WFGY topologically sorts and starts them in safe order.
|
||
|
||
2. **Ping Chain**
|
||
Creates a synthetic resource (tiny doc, dummy secret) that satisfies
|
||
downstream health‑checks, then swaps once the *real* resource is ready.
|
||
|
||
3. **BBCR Timeout**
|
||
If a health probe exceeds `deadlock_timeout` (default = 120 s) WFGY aborts
|
||
the loop, logs a graph diff, and optionally retries with jitter.
|
||
|
||
4. **Boot Checkpoint** *(shared module)*
|
||
Guards secrets or config maps so apps don’t boot until keys exist.

## ✍️ Demo — Index ↔ Retriever Deadlock
|
||
|
||
```txt
|
||
⏳ retriever‑svc waiting for index (0/1 ready)
|
||
⏳ index‑builder waiting for retriever ping (0 docs)
|
||
|
||
WFGY Deadlock Monitor:
|
||
• Cycle detected: index‑builder ⇆ retriever‑svc
|
||
• Injecting warm‑doc workaround … OK
|
||
• retriever‑svc ready (1/1) delta = 12 s
|
||
• index‑builder ingested 120 K vectors
|
||
• warm‑doc deleted — live traffic enabled ✅

## 🗺️ Module Cheat‑Sheet
|
||
|
||
| Module | Role |

|
||
| **Dependency Graph** | Topo‑sort service order |
|
||
| **Ping Chain** | Synthetic resource break‑loop |
|
||
| **BBCR Timeout** | Abort & retry long waits |
|
||
| **Boot Checkpoint** | Shared boot guard for secrets/config |

||
|
||
| Feature | State |
|
||
| --------------------------- | ---------- |
|
||
| Topo‑sort deploy graph | ✅ Stable |
|
||
| Synthetic warm‑doc injector | ⚠️ Beta |
|
||
| BBCR deadlock timeout | ✅ Stable |
|

||
## 📝 Tips & Limits
|
||
|
||
* Keep cycles visible: run `wgfy graph viz` to spot latent loops.
|
||
* Tune `deadlock_timeout` per environment; GPUs often need longer.
|
||
* For cross‑cloud deployments, enable `ping_chain.remote = true`.
