Merge the S18-S36 scenario ideas into the official peer-cli scenario matrix
and add a Docker-backed runner that now exercises S1-S36 with concrete file
proofs. The runner creates temporary fixtures under .lanspread-peer-cli, drives
JSONL peer containers, checks transferred roots with diff and SHA-256 manifests,
and covers startup, discovery, transfer, failure, mutation, concurrency, mesh,
lifecycle, and catalog edge cases.
The scenarios exposed a few harness/runtime boundary gaps that would otherwise
make the contract ambiguous. The peer CLI now rejects self-connects, rejects
commands for game IDs outside the receiver catalog, filters unknown remote games
from its command/event surface, and reports duplicate active same-game commands
as operation-in-progress errors. The peer core also refuses non-catalog download
commands before transfer, and PeerGameDB has a unit check that address changes
preserve identity and library state.
S12 and S28 remain unit-level invariants because the CLI cannot stably race raw
serve-gate requests or rebind a live listener without restart. The runner treats
those scenarios as covered by just test and checks the expected unit test names
appear in the output.
Test Plan:
- just fmt
- python3 -m py_compile crates/lanspread-peer-cli/scripts/run_extended_scenarios.py
- RUSTC_WRAPPER= just test
- RUSTC_WRAPPER= just clippy
- RUSTC_WRAPPER= just peer-cli-build
- just peer-cli-image
- python3 crates/lanspread-peer-cli/scripts/run_extended_scenarios.py
- git diff --check
