chore(consolidation): migrate from blackroad-os-ideas and blackroad-os-research

## Summary
- Migrates roadmaps and RFCs from `blackroad-os-ideas`
- Migrates research papers from `blackroad-os-research`
- Part of Phase 1 BlackRoad OS consolidation

## Files Added
- `docs/roadmap/` - 2025 roadmaps
- `docs/rfc/` - RFC templates
- `docs/ideas/` - Idea proposals
- `docs/papers/` - Research papers (PS-SHA, SIG, finance automation)
- `docs/research/` - Research prompts

## Test plan
- [ ] Verify docs build
- [ ] After merge, archive source repos

+# Contradiction Handling in BlackRoad OS
+
+Agents operate in a trinary logic space (true, false, unknown) where contradictions are treated as signals rather than silent errors. BlackRoad OS treats conflicts as first-class events that demand routing, journaling, and potentially escalation to orchestrators or human operators.
+
+## What is a Contradiction?
+
+A contradiction occurs when two or more beliefs, observations, or recommended actions cannot simultaneously hold. Examples include conflicting risk assessments across agents or incompatible compliance flags in finance workflows.
+
+## Escalation Mechanism
+
+1. **Detection:** Agents flag contradictions when belief vectors clash or when policy checks diverge.
+2. **Event emission:** A contradiction event is emitted to the orchestrator or higher-level mediator.
+3. **Reconciliation:** The orchestrator aggregates evidence, applies policy (e.g., majority vote, priority weighting, or regulatory override), and proposes a resolution.
+4. **Outcome recording:** Both accepted and rejected branches are recorded for transparency and future replay.
+
+## Integration with PS-SHA∞
+
+Contradiction resolution steps are journaled as PS-SHA∞ entries:
+
+- Record the competing claims and confidence scores.
+- Capture the chosen resolution rule and rationale.
+- Link branches through `previousHash` values so discarded paths remain inspectable.
+
+## TODOs
+
+- Define standardized contradiction event payloads for ingestion by `blackroad-os-operator`.
+- Prototype escalation thresholds in `/experiments/contradiction-sim` to tune sensitivity.
