meridian-dock 0.3.0

Convergence debt and meridian docking protocols for multi-agent systems

Meridian v0.3

Thin docking protocols that bound convergence debt — the cost of becoming able to meet again after independent success.

Not a chain. Not shared rewards. Not full ontology merge.

What we actually found (short)

1. Convergence debt is real — local success drives meetability to zero.
2. Thin docks restore the bargain — no shared goals required.
3. Hidden interfaces are recoverable — Debt-Gradient PCA from a scalar friction meter.
4. Private objectives stay private — transfer attacks fail on private R².
5. Debt scales with N — meridians stay thin.
6. Rendezvous is poisonable — hash-pin / quorum / dual-rail defend it.
7. Rotation needs ceremony — parent hash + signatures + policy (HMAC or Ed25519).
8. It runs for real agents — tools, files, multi-process, OpenAI/LangGraph hooks.

60-second product loop

meridian rendezvous init .\rendezvous.json
meridian dock init .\agent.dock.json --rendezvous .\rendezvous.json
meridian dock maintain .\agent.dock.json --rendezvous .\rendezvous.json

from meridian import MeridianMiddleware, MiddlewareConfig
from meridian.adapters import OpenAIToolsAdapter, OpenAIStyleTool

mw = MeridianMiddleware("rendezvous.json", "agent.dock.json",
                        config=MiddlewareConfig(defense="hash_pin"))
mw.start()

# adapter.handle_tool_calls(tool_calls)

Ed25519 rotation (Exp-007):

from meridian import PkiParty, pki_sign_proposal, pki_activate_if_quorum
from meridian.rotation import make_proposal, legitimate_upgrade, rendezvous_signature
# parties sign with private keys; verifiers use public keys only

Core idea

1. Publish a rendezvous dock signature.
2. Maintain each agent’s public dock every tool turn.
3. Specialize privately off-dock.
4. Rotate only via signed quorum + breaking-change policy (HMAC or Ed25519).
