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-16: Safe Vault Operations for Call Protocol Exposure
|
|
|
|
- **Origin**: [operation-registry.md](crates/call/operation-registry.md), ADR-008
|
|
- **Status**: resolved
|
|
- **Door type**: One-way
|
|
- **Priority**: high
|
|
- **Resolution**: No vault operations are exposed over the call protocol. The vault is accessed only at the assembly layer (CLI binary at startup). Handlers receive secret material through `OperationContext.capabilities`, not by calling vault operations over the wire. The `operation-registry.md` spec previously showed `vault/derive`, `vault/unlock`, and `vault/decrypt` registered as call protocol operations — that was a contradiction with ADR-008's "capability source" model and has been corrected. See ADR-014.
