WFGY Problem Map 1.0 — 16 reproducible failure modes

Think of this page as a desk within a ward.
If you need the full triage and all prescriptions, return to the Emergency Room lobby.

Use this page when Tabnine autocompletes the wrong API, mixes symbols across packages, or flips outputs between local and cloud contexts. The fixes route back to WFGY pages with measurable targets so you can verify without changing infra.

Core acceptance

ΔS(question, retrieved) ≤ 0.45
Coverage ≥ 0.70 to the target function or spec anchor
λ remains convergent across three paraphrases and two seeds
E_resonance stays flat across long edit plans

Fix in 60 seconds

Measure ΔS Compute ΔS(question, retrieved) and ΔS(retrieved, expected anchor). Stable < 0.40, transitional 0.40–0.60, risk ≥ 0.60.
Probe λ_observe Toggle local versus cloud context and vary k. Pin reranker. If ΔS stays flat and high, suspect metric or index mismatch. If λ flips on harmless header reorder, lock schema and clamp with BBAM.
Apply the module

Retrieval drift in code or docs → BBMC plus Data Contracts
Reasoning collapse in long refactors → BBCR bridge plus BBAM, verify with Logic Collapse
Dead ends in edit plans or test generation → BBPF alternate paths
Hybrid search worse than single → Pattern Query Parsing Split and Rerankers

Verify Coverage ≥ 0.70 on three paraphrases. λ convergent on two seeds. Same diff twice.

Typical Tabnine breakpoints and the right fix

Local vs cloud index skew Suggestions differ after a reboot or network switch. Warm up the selected index, fence first run, verify analyzer settings. Open: Bootstrap Ordering
Wrong symbol in a monorepo Near neighbor symbols from sibling packages win due to similarity. Lock anchors to repo@commit and subdir, require cite then explain. Open: Retrieval Traceability, Embedding ≠ Semantic
Generated tests reference phantom helpers Enforce file spans and commit SHA before test generation. Open: Data Contracts
Plan loops during multi file edits Split plan and re join with a bridge step. Clamp variance in the patch step. Open: Context Drift, Entropy Collapse
Similarity high but meaning wrong Metric or normalization mismatch or fragmented store. Rebuild with explicit metric and fix fragmentation. Open: Embedding ≠ Semantic, Vectorstore Fragmentation
Unsafe shell or tool suggestions copied from docs Lock tool allow lists, require SCU separation for untrusted text. Open: Prompt Injection, Pattern: SCU
Org policy or model switch changes outputs silently Make refusal paths explicit. Echo the active policy and model in the plan. Open: Multi-Agent Problems, Data Contracts

IDE checklist for Tabnine

Warm up the selected context source and verify INDEX_HASH, credentials, and policy mode.
Use one retrieval metric per run. Do not mix analyzers while fixing one bug.
Prompts carry anchors: repo@commit, file_path, symbol, line_start, line_end, snippet_id.
Log per step: ΔS, λ state, coverage. Alert when ΔS ≥ 0.60 or λ diverges.
Regression gate requires tests pass, coverage ≥ 0.70, ΔS ≤ 0.45, identical diff twice.

Minimal schema you should capture

{ repo, commit_sha, file_path, symbol, line_start, line_end, snippet_id, tokens, ΔS, λ_state } Require cite then explain. Forbid cross file reuse without a new citation.

Deep diagnostics

Three paraphrase probe Ask the same change three ways. If λ flips, clamp with BBAM and lock headers.
Anchor triangulation Compare ΔS for target vs decoy file or sibling package. If close, re chunk and normalize embeddings. See: Retrieval Playbook, Embedding ≠ Semantic
Plan length audit If entropy rises after 25 to 40 steps, split the plan and re join with a BBCR bridge. See: Entropy Collapse
Live instability Add probes and backoff guards in IDE tasks. See: Live Monitoring for RAG, Debug Playbook

Copy paste prompt for Tabnine chat

You have TXTOS and the WFGY Problem Map loaded.

My Tabnine issue:
- symptom: [one line]
- anchors: repo={name}, commit={sha}, file={path}, lines={a..b}
- traces: ΔS(question,retrieved)=..., ΔS(retrieved,anchor)=..., λ across 3 paraphrases

Tell me:
1) the failing layer and why,
2) the exact WFGY page to open,
3) minimal steps to push ΔS ≤ 0.45 and keep λ convergent,
4) a reproducible test to verify the fix.
Use BBMC, BBPF, BBCR, BBAM when relevant. Keep it auditable and short.
