glm-5.2 1baa619ce9 docs(arch): decompose open-questions.md into per-OQ files under questions/
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-15: Call Protocol Client and Adapter Contract

  • Origin: call-protocol.md, operation-registry.md, ADR-013
  • Status: resolved
  • Door type: One-way
  • Priority: high
  • Resolution: CallClient opens QUIC connections and shares the dispatch loop with CallAdapter — both sides can send and receive call.requested once connected. Connection direction (who opened the connection) is independent of call direction (who calls whom). from_call adapter discovers remote operations via services/list + services/schema and registers them with forwarding handlers — same pattern as from_openapi and from_mcp. to_openapi and to_mcp project local operations to external protocols. Adapter contract trait (OperationAdapter) produces (OperationSpec, Handler) pairs. Cross-node call tree: abort cascade (ADR-016) propagates across node boundaries through from_call handlers. Credentials for connections come from capabilities (ADR-014). Adapter-registered operations are Internal by default (ADR-015). See ADR-017.
