Three ADRs addressing gaps surfaced by the first hub consumer (alkapi):
- ADR-067: Aggregated peer-env wiring — Dispatcher::with_aggregated_env hook
so compose_root_env reads a shared PeerCompositeEnv across all calls,
not a fresh per-call one. The hub-defining gap (alkapi OQ-08 / G.1).
- ADR-068: PeerCompositeEnv::peer_operations override — adds
list_operation_names() to OperationEnv, overrides on OverlayOperationEnv
and PeerCompositeEnv. Fixes services/list-peers returning empty operation
lists for non-local peers (alkapi G.6).
- ADR-069: from_call is a manual free function, not auto-wired — reverses
the aspirational OQ-27 resolution to match the implementation. Cleans
the 'v1 default' hedging language in ADR-017 and client-and-adapters.md
(alkapi G.4).
New crate spec: alknet-hub — reusable hub pattern (aggregated env,
connection lifecycle, worker supervision with backoff, service discovery).
Spec fixes: builder API drift (with_local/with_local_streaming separation),
ScopedOperationEnv → ScopedPeerEnv type name, OQ count 51→54.
Three new OQs: OQ-52 (wait_for_close), OQ-53 (backoff defaults),
OQ-54 (inbound hook placement).
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.
