gongzhiyongandOmX fc877dad24 Move remaining docs into docs index
Keep the repository root focused on README while moving the remaining planning and swarm test documents under docs/ and indexing them there.

Constraint: The user explicitly requested that documents should live under docs/.

Rejected: Leaving older root-level Markdown files in place | it keeps the homepage cluttered and splits the documentation surface.

Confidence: high

Scope-risk: narrow

Directive: Keep future ordinary documentation under docs/ unless it is a root entrypoint such as README.md.

Tested: git diff --cached --check; find . -maxdepth 1 -type f -name '*.md' shows only README.md.

Not-tested: No runtime tests rerun because this is a documentation path-only move.

# Swarm Test Input / Output Report
This report shows the actual deterministic test content for the minimal swarm
prototype. It separates the swarm-behavior tests from the traditional-vs-swarm
comparison benchmark.
## Commands Executed
```bash
./.venv/bin/python -u -B examples/run_swarm_behavior_acceptance.py
./.venv/bin/python -u -B examples/run_swarm_vs_traditional_benchmark.py
```
Both commands returned `status: PASS`.
## Behavior Test Content
### B01: Single Agnet Failure Isolation
Purpose: prove one failed Agnet does not collapse the swarm result.
Input:
```json

`tests/test_swarm_behavior_academic.py::test_single_agnet_failure_isolated_by_redundant_convergence`.
### B02: Emergent Consensus From Local Evidence
Purpose: prove group-level aggregation can beat the best single local signal.

## Traditional vs Swarm Benchmark Content
### Baseline Definitions
Traditional Agnet:
```json
[
"single agent fails closed when its one route fails",
"best-of local answers without shared-state aggregation",
"FIFO task selection without pheromone feedback",
"stateless handoff without active-agent/payload continuity"
]
```
Swarm Agnet:
```json
[
"redundant agents share task pool and converge despite a failed individual",
"local observations accumulate through shared_state",
"pheromone scores bias claim order and final selection",
"handoff records active agent, transfer target, and payload continuity"
]
```

## Full Benchmark Output
```json
{
"standard": "swarm-vs-traditional-deterministic-benchmark-v1",
"status": "PASS",
"overall_normalized_score": {
"traditional": 0.1958,
"swarm": 0.9175,
"relative_gain_percent": 368.5,

}
}
```
## Verification Boundary
This report proves deterministic behavior for the four selected swarm properties:
fault isolation, emergence, pheromone coordination, and handoff continuity. It
does not prove all production-scale properties, large-cluster performance,
malicious-agent resistance, or certified compatibility with the external
LangGraph package.
