feat(ring-0): RING 0 seal — cargo build + cargo test green + 7 tools verified

[gHashTag]

RING 0 — Foundation Seal

Context

trios-server exists with 7 MCP tools in crates/trios-server/src/tools.rs:

• git_status, git_stage_files, git_unstage_files, git_commit, git_create_branch
• gb_list_branches, gb_push_stack

MCP handler in crates/trios-server/src/mcp.rs, Axum server on port 9005.

Mission

Seal RING 0 — prove the spine is alive before any integration.

Steps (PHI LOOP)

R1 — Build

cargo build --release
# Must: 0 errors, 0 clippy warnings
cargo clippy -- -D warnings

R2 — Tests

cargo test
# Must: all tests green

R3 — Server smoke test

# Start server
cargo run -p trios-server -- --port 9005 &

# List tools
curl -s http://localhost:9005/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}' | jq .

# Must return 7 tools

R4 — git_status smoke

curl -s http://localhost:9005/mcp \
  -H "Content-Type: application/json" \
  -d "{\"jsonrpc\":\"2.0\",\"id\":2,\"method\":\"tools/call\",\"params\":{\"name\":\"git_status\",\"arguments\":{\"repo_path\":\"$(pwd)\"}}}" | jq .
# Must return changed files list (not error)

R5 — Seal

echo "{\"ring\": 0, \"sha\": \"$(git rev-parse HEAD)\", \"tools\": 7, \"tests\": \"all green\", \"date\": \"$(date -u +%Y-%m-%dT%H:%M:%SZ)\"}" \
  > .trinity/experience/ring-0-seal.json

echo "[$(date -u +%Y-%m-%dT%H:%M:%SZ)] RING0: cargo build + test green | 7 tools verified | port 9005 alive" \
  >> .trinity/experience/trios_$(date +%Y%m%d).trinity
