Synthesizes the multi-thread discussion that surfaced during the peer-graph
routing research (ADR-029) and OQ-33/34 resolution. Three separate threads
(peer identity, filesystem POC, old storage spec) converged on the same
question: where does persistent state live in the alknet crate graph, and
what's the shared infrastructure for it.
Key commitments documented:
- SQLite + honker is the foundation (pattern, not a crate — ~20 lines per
consumer). The metagraph is one tool built on it, for graph-shaped
problems. Direct tables are another tool, for table-shaped problems.
- IdentityProvider is the auth repo trait (already exists in core, make the
pattern explicit). Adapters implement it (Config, SQLite, future
Redis/remote/automerge). PeerStore is adapter-internal, not core.
- Per-node ACL, no 'trusted' flag. Each node authorizes its direct callers
via AccessControl::check(identity). No global ACL, no replication. The
hub authorizes the user; the spoke authorizes the hub. Same mechanism.
- Forwarded-for identity as metadata, not authority. The from_call handler
includes the original caller's identity in the call payload; the spoke's
ACL authorizes the hub (direct caller), never the forwarded_for. The ACL
check signature prevents misuse.
- The ACL check stays table-shaped (flat scope match); the delegation graph
(future) produces effective scopes at resolution time. They compose at the
IdentityProvider boundary.
- The hub proxy tangle: ACL (authorize), bucket routing (operation input),
peer routing (PeerRef) are three separate layers. Bucket-level
authorization is handler logic, not protocol logic.
What the old spec had that's dropped: multi-tenant (each tenant gets own
setup), secrets module (replaced by vault), metagraph-as-foundation (demoted
to tool), single storage crate (split by concern), accounts/orgs (deferred —
v1 is a peers table).
