State Fork — Guardrails and Fix Pattern

🧭 Quick Return to Map

You are in a sub-page of MemoryLongContext.
To reorient, go back here:

• MemoryLongContext — extended context windows and memory retention
• WFGY Global Fix Map — main Emergency Room, 300+ structured fixes
• 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.

When the same task_id is held in multiple tabs, agents, or sessions, their memories may diverge.
This creates two or more competing state branches, producing unstable or contradictory answers.

---

Symptoms

• Two browser tabs answer the same task differently.
• Multi-agent orchestration produces conflicting citations.
• Session resumes but history appears rewritten or selectively dropped.
• Answers alternate between two incompatible interpretations.
• Logs show inconsistent mem_rev or mem_hash values for the same task_id.

---

Root causes

• Concurrent writes to the same memory namespace.
• Missing checks for mem_rev version control.
• Agents refreshing at different times and overwriting buffers.
• Weak schema: task identity not fenced by {task_id, mem_rev, mem_hash}.
• No conflict resolution logic when branches emerge.

---

Fix in 60 seconds

1. Version control memory

   • Every write stamped with {task_id, mem_rev, mem_hash}.
   • Reject writes if mem_rev < server mem_rev.
   • Require conflict resolution if two branches exist.

2. Isolate namespaces

   • Each agent/tab gets unique memory slot.
   • If collaboration required, merge through a coordinator agent.

3. Detect divergence early

   • Measure ΔS(answerA, answerB) across tabs.
   • If ΔS ≤ 0.40 but snippets differ, state fork detected.

4. Resolve fork

   • Run reconciliation: pick majority snippet set, or force human confirm.
   • Hash merged state and issue new {mem_rev, mem_hash}.

5. Trace schema

   • Require all claims to cite snippet ids.
   • Reject orphan claims without snippet anchors.

Copy-paste diagnostic prompt

You have TXTOS and the WFGY Problem Map.

Task: Detect and repair state forks across tabs or agents.

Protocol:
1. Print {task_id, mem_rev, mem_hash}.
2. If two active branches share task_id with different mem_rev → flag fork.
3. Compare ΔS(answerA, answerB).
   - If ΔS ≤ 0.40 but snippets differ → fork confirmed.
4. Apply resolution:
   - Choose majority snippet set or request human input.
   - Issue new {mem_rev, mem_hash}.
5. Report ΔS, λ states, and resolution path.

---

Acceptance targets

• No conflicting branches for the same task_id.
• All writes validated against server-side mem_rev.
• ΔS(answerA, answerB) ≥ 0.60 after resolution.
• λ remains convergent across three paraphrases.
• Audit log records merge or reject actions explicitly.
