A new sibling Python package, `crisis_agents`, that lifts the Crisis
protocol from "consensus between machines" to "consensus between AI
agents". Threat model: a team of sub-agents normally talks freely
with its orchestrator (the "mothership"); when the team's boundary
opens and an external agent of unknown trust joins, the mothership
activates the Crisis layer so byzantine equivocation is detectable.
Two-phase orchestration model:
Phase 1 — closed team, no Crisis: agents emit claims directly, the
mothership collects them flat.
Phase 2 — boundary opens: every subsequent claim is wrapped into a
Crisis Message with the agent's stable process_id and a PoW nonce,
delivered into per-agent LamportGraphs, and after each turn the
mothership scans for mutations via LamportGraph.find_mutations.
Phase 3 — proof: when an alarm fires, the mothership emits a
replayable JSON proof-of-malfeasance document with the contradictory
witnesses, their delivery sets, and DAG cross-references showing
which honest agents saw what.
Modules:
- claim.py Claim dataclass + JSON round-trip
- boundary.py membership tracker + open() trigger
- agent.py CrisisAgent abstract + MockAgent + MockByzantineAgent
(the latter equivocates by emitting two variants to
disjoint peer subsets at the same logical turn)
- mothership.py orchestrator driving both phases, building Crisis
Messages from Claims, per-agent LamportGraphs, log
- alarm.py scan_for_mutations: same-agent same-turn distinct
digests with non-identical delivery sets, verified
spacelike via LamportGraph.are_spacelike on the
honest-agent graphs
- proof.py build_proof + ProofDocument + JSON serializer +
verify_proof_self_consistent
- cli.py `crisis-agents demo` + `crisis-agents verify`
- scenarios/ fact_check: reference doc + 6 statements + scripted
honest/byzantine agents producing a deterministic
equivocation on statement s03
Tests: 50 new tests across test_claim, test_boundary, test_mothership,
test_alarm, test_proof, test_demo_fact_check. End-to-end test runs the
fact_check scenario, asserts exactly one alarm raised, proof is built,
re-serialized JSON passes self-consistency. Full suite (existing
crisis + new crisis_agents) green in 0.77s — 145 tests.
Out of scope (deliberately): visualization (separate CrisisViz upgrade
later), real TCP gossip (agents talk via in-process function calls in
the mothership), false-claim detection without equivocation (an
agent that consistently lies but never equivocates is out-voted, not
"caught"; catching it would require a ground-truth oracle).
Reuse from existing crisis package: Message, Vertex, LamportGraph,
LamportGraph.find_mutations, ProofOfWorkWeight, digest. The new code
is a thin adapter layer; the protocol substrate did the heavy lifting.

The repo had no LICENSE file and pyproject.toml claimed CC-BY-4.0
— a license that isn't designed for code and conflicts with the
project's actual intent of letting people fork, learn from, and
redistribute the implementation. The paper itself remains CC-BY-4.0
as a separately licensed artifact; that fact is now stated in the
LICENSE file and in the parent README.
