📒 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

Dependency Graph
Services declare needs: edges in wgfy.yaml.
WFGY topologically sorts and starts them in safe order.
Ping Chain
Creates a synthetic resource (tiny doc, dummy secret) that satisfies downstream health‑checks, then swaps once the real resource is ready.
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.
Boot Checkpoint (shared module)
Guards secrets or config maps so apps don’t boot until keys exist.

✍️ Demo — Index ↔ Retriever Deadlock

⏳  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

📊 Implementation Status

Feature	State
Topo‑sort deploy graph	✅ Stable
Synthetic warm‑doc injector	⚠️ Beta
BBCR deadlock timeout	✅ Stable
Secrets boot guard	🛠 Planned

📝 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.
