# 📒 Problem #16 ·Pre‑Deploy Collapse Problem Map *“Everything looked fine in CI… until **nothing** booted in prod.”* Pre‑deploy collapse happens **before** a single user query is served. Migrations pass, tests are green, images ship — yet the first container crashes or the very first LLM call returns a 500. Common root causes: * Model checkpoint ≠ tokenizer version * Env var misspells (e.g., `OPEN_API_KEY` vs `OPENAI_API_KEY`) * Hidden f‑strings / Jinja placeholders left unresolved * GPU drivers mismatch container base (CUDA 11 vs 12) WFGY’s *pre‑flight sanity layer* runs a semantic diff between **declared** runtime and **effective** runtime, catching mismaps before traffic starts. --- ## 🚨 Typical Pre‑Deploy Collapses | Pattern | Real‑World Fallout | | ------------------------------------- | ------------------------------------ | | Tokenizer / checkpoint version skew | Embeds garbage; queries 0 % recall | | Missing secret in K‑V store | First API call 401 / segfault | | CUDA / driver mismatch | GPU container exits code 139 | | Undigested template vars (`{{ }}`) | Prompt crashes, empty completions | --- ## 🛡️ WFGY Pre‑Flight Guards | Collapse Pattern | Guard Module | Remedy | Status | | --------------------- | ----------------------- | ------------------------------------ | ------ | | Version skew | **SemVers Diff** | Abort deploy if `model.json` ↔ runtime mismatch | ✅ Stable | | Missing secret | **Boot Checkpoint** | Block start until secret present | ✅ Stable | | Driver mismatch | **Cuda‑Probe** | Warn & fall back to CPU safe mode | ⚠️ Beta | | Stray `{{var}}` tokens| **Prompt Lint** | Fail CI; highlight undeclared vars | ✅ Stable | --- ## 📝 How It Works 1. **SemVers Diff** Parses `model‑card.json`, compares `tokenizer_sha`, `pytorch_sha`, `cuda`, etc., with container runtime; throws if mismatch unless `--force`. 2. **Boot Checkpoint** *(shared)* Kubernetes init‑container polls secret store; fails pod after `secret_timeout`. 3. **Cuda‑Probe** Minimal `nvidia‑smi` check; if driver ≠ compiled CUDA, WFGY rewrites env `CUDA_VISIBLE_DEVICES=""` and logs downgrade. 4. **Prompt Lint** CI step: scans prompts for `{{ }}` or `${}` tokens lacking a default in `prompt_vars.yaml`. --- ## ✍️ Demo — Tokenizer Version Skew ```bash $ wgfy preflight ✔ env vars ............... OK ✖ checkpoint ↔ tokenizer .. MISMATCH • model: facebook/llama‑2‑7b‑chat‑hf tokenizer‑sha = `ad4c1b9` • runtime: tokenizer‑sha = `9e7f02d` → Aborting deploy (use --force to override) ```` --- ## 🗺️ Module Cheat‑Sheet | Module | Role | | ------------------- | ------------------------------- | | **SemVers Diff** | Catch model / tokenizer skew | | **Boot Checkpoint** | Ensure secrets & config exist | | **Cuda‑Probe** | Verify GPU driver compatibility | | **Prompt Lint** | Fail CI on stray template vars | --- ## 📊 Implementation Status | Feature | State | | ------------------------ | -------- | | SemVers diff | ✅ Stable | | Boot checkpoint | ✅ Stable | | Cuda‑probe fallback | ⚠️ Beta | | Prompt lint in CI action | ✅ Stable | --- ## 📝 Tips & Limits * Add `ignore_versions: ["minor"]` in `wgfy.yaml` to allow 1‑patch drifts. * Set `secret_timeout = 90s` for slower vaults. * GPU fallback adds \~0.4 s latency per request — tune `cuda_probe.mode`. --- ### 🔗 Quick-Start Downloads (60 sec) | Tool | Link | 3-Step Setup | |------|------|--------------| | **WFGY 1.0 PDF** | [Engine Paper](https://github.com/onestardao/WFGY/blob/main/I_am_not_lizardman/WFGY_All_Principles_Return_to_One_v1.0_PSBigBig_Public.pdf) | 1️⃣ Download · 2️⃣ Upload to your LLM · 3️⃣ Ask “Answer using WFGY + \” | | **TXT OS (plain-text OS)** | [TXTOS.txt](https://github.com/onestardao/WFGY/blob/main/OS/TXTOS.txt) | 1️⃣ Download · 2️⃣ Paste into any LLM chat · 3️⃣ Type “hello world” — OS boots instantly | --- ### 🧭 Explore More | Module | Description | Link | |-----------------------|----------------------------------------------------------|----------| | WFGY Core | WFGY 2.0 engine is live: full symbolic reasoning architecture and math stack | [View →](https://github.com/onestardao/WFGY/tree/main/core/README.md) | | Problem Map 1.0 | Initial 16-mode diagnostic and symbolic fix framework | [View →](https://github.com/onestardao/WFGY/tree/main/ProblemMap/README.md) | | Problem Map 2.0 | RAG-focused failure tree, modular fixes, and pipelines | [View →](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rag-architecture-and-recovery.md) | | Semantic Clinic Index | Expanded failure catalog: prompt injection, memory bugs, logic drift | [View →](https://github.com/onestardao/WFGY/blob/main/ProblemMap/SemanticClinicIndex.md) | | Semantic Blueprint | Layer-based symbolic reasoning & semantic modulations | [View →](https://github.com/onestardao/WFGY/tree/main/SemanticBlueprint/README.md) | | Benchmark vs GPT-5 | Stress test GPT-5 with full WFGY reasoning suite | [View →](https://github.com/onestardao/WFGY/tree/main/benchmarks/benchmark-vs-gpt5/README.md) | | 🧙‍♂️ Starter Village 🏡 | New here?
