📒 Map-D ·Problem #6 · Logic Collapse & Recovery — Dead‑End Paths, Frozen Threads

Long chains of reasoning can hit a wall: the model reaches a step where no rule fires, context drifts, or the answer space “locks‑up.”
Instead of recovering, most LLM stacks keep emitting filler or restart from scratch — losing the entire logic trail.
WFGY turns these dead ends into detours: it detects the stall, rolls back to the last sane node, and spawns a fresh branch.

🤔 Why Do Chains Collapse?

Root Cause	Practical Failure
Semantic Dead‑End	Model encounters a state where next‑token entropy flattens
Hidden Residue Build‑Up	ΔS rises gradually → logic tension snaps all at once
No Checkpoint Memory	System can’t roll back to a stable frame
Blind Retry	Pipelines re‑run the same faulty path, freezing or looping

🛡️ WFGY Logic‑Recovery Stack

Layer	Action
ΔS Spike Watch	Detects sudden tension jump (> 0.6) signalling stall
λ_observe Divergence	Flags when flow turns chaotic (λ = ×)
BBCR Collapse–Rebirth	Auto‑rollback to last good Tree node, spawn new branch
Tree Checkpoint	Every major step stored → instant “hot‑save” for rollback
Residue Flush (BBMC)	Clears semantic residue before replaying the fork

⚠️ Logic collapse detected at Step 7  
↩︎ Rolling back to Node 5 (ΔS 0.28, λ →)  
🡒 Replaying with alternate path…

✍️ Quick Test (90 sec)

1️⃣  Start
> Start

2️⃣  Load a multi‑step proof chunk
> "Proof outline: Step 1…Step 7 (missing lemma)…"

3️⃣  Ask the model to complete
> "Finish the proof"

Watch WFGY:
• ΔS spikes at the missing lemma  
• BBCR rolls back to Step 5  
• Proposes alternate lemma or asks for user input

🔬 Sample Output

Logic dead‑end at sub‑lemma (Step 7).  
Restored context to Step 5.  
Proposed fix: supply definition of ‘bounded operator’ or upload missing section.

Progress resumes instead of endless loops.

🛠 Module Cheat‑Sheet

Module	Role
ΔS Metric	Detects stall threshold
λ_observe	Judges flow direction / chaos
BBCR	Rollback & branch spawn
Semantic Tree	Stores checkpoints for hot rollback
BBMC	Purges leftover residue before restart

📊 Implementation Status

Feature	State
ΔS spike detection	✅ Stable
BBCR rollback / branch	✅ Stable
Auto user prompt on dead‑end	✅ Basic
Multi‑fork replay	⚠️ Planned

📝 Tips & Limits

Collapse guard works even on pasted text without a retriever.
Repeated collapses on the same node → supply missing context.
Share tricky logs in Discussions; they refine stall thresholds.
