The monolithic open-questions.md (1310 lines, 47 OQs) was large enough to be unmanageable, with high size variance (OQ-42 at 220 lines next to OQ-06 at 8). Decomposed into one file per OQ under docs/architecture/questions/ (NNN-slug.md, mirroring the ADR convention), with open-questions.md retained as the index: theme-grouped tables plus a cross-theme Deferred/Blocked section that surfaces the 6 deferred OQs with their Blocked-on conditions inline (the safe-exit visibility surface). Per-OQ content moved verbatim; all 62 inbound links stay valid (none used anchors). README's curated OQ summary dropped (now redundant with the index tables). Also seeds tasks/architecture/ with this task plus two follow-ups found during the decompose: OQ-09/10 missing structured Blocked-on fields, and the tasks/architecture/ blocker-task half of the Safe Exit protocol being unenforced.

# OQ-30: PeerRef::Any Routing Policy
|
|
|
|
- **Origin**: [ADR-029](decisions/029-peer-graph-routing-model.md) §2, [client-and-adapters.md](crates/call/client-and-adapters.md), `docs/research/alknet-call-peer-routing/findings.md` §3.2
|
|
- **Status**: **resolved** (2026-06-27)
|
|
- **Door type**: Two-way
|
|
- **Priority**: low
|
|
- **Resolution**: `PeerRef::Any` uses **insertion-order first-match** —
|
|
deterministic but order-dependent (worker A connects before worker B →
|
|
`Any` routes to A until A disconnects). This is the simplest routing
|
|
policy and is correct for the immediate use case (the head picks the
|
|
first worker that serves the op). A richer `RoutingPolicy` (round-robin,
|
|
least-loaded, affinity) is a feature extension — the `PeerRef` enum is
|
|
designed to compose with a `Route { selector, policy }` struct without
|
|
breaking the `invoke_peer` signature. Adding a routing policy is
|
|
non-breaking; it's a feature addition when a fan-out use case needs it,
|
|
not an unmade architectural decision.
