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-18: Privilege Model and Authority Context
|
|
|
|
- **Origin**: [operation-registry.md](crates/call/operation-registry.md)
|
|
- **Status**: resolved
|
|
- **Door type**: One-way (ACL model), two-way (specific APIs)
|
|
- **Priority**: high
|
|
- **Resolution**: The `internal` flag on `OperationContext` marks calls that originated from composition (a handler calling another operation via `OperationEnv`), as opposed to external calls that arrived as `call.requested` from a wire client. The `internal` flag switches the authority context: the ACL check runs against the composing handler's identity (set at registration), not the caller's identity and not as a blanket skip. This replaces the previous `trusted` flag, which skipped ACL entirely — a privilege escalation vector. Operations have External/Internal visibility. Internal operations return `NOT_FOUND` when called from the wire and are excluded from `services/list`. The composition env is scoped — a handler can only invoke a declared set of operations. Handler identity is carried on `OperationContext` alongside caller identity (the principal/agent pair). See ADR-015.
