feat: integrate operation-boundary authorization

Merge reviewed source a35d9a3d45 into develop after Subject deletion. Preserve deletion fencing before Job authorization, retain both test modules, and regenerate combined API artifacts.

 //! Neutral explicit-allow authorization contracts. Resource containment never crosses kinds.
 //!
-//! # Trusted Feature boundary
+//! # Trusted operation boundary
 //!
-//! A Profile requests execution configuration, not authority. The Worker asks the
-//! Host for each enabled Feature's exact activation name before initialization,
-//! then trusted Feature code asks for each protected operation and its semantic
-//! resource before access or effects. `ticket` on [`PermissionResource::Feature`]
-//! activates Ticket; it implies neither `ticket.create` nor any future operation.
-//! `ticket.create` on a Workspace permits creation there but cannot activate the
-//! Feature. There are no wildcard permissions or implicit dotted-name inheritance.
+//! A Profile requests local composition, not authority. Feature registration and
+//! session-local state need no authorization. Trusted Feature/Host adapters check
+//! each protected read, model supply, subscription or effect immediately before
+//! it occurs; continued background work repeats that check. MCP alone retains
+//! temporary exact activation permission on [`PermissionResource::Feature`]
+//! before discovery can spawn a process.
 //!
-//! Identity is absent from the authorization request intentionally: the Host
-//! authenticates the bound Runtime/Worker and resolves current source permissions,
-//! body ownership and any per-Worker execution grant. A shared client, Profile,
-//! remembered receipt or caller-supplied Subject claim is not authority. Features
-//! depend on this contract, never on a particular Subject policy implementation.
+//! Identity is absent from requests: the Host authenticates the bound Runtime/Worker
+//! and resolves current source policy, body ownership, delegation and Job attenuation.
+//! Bound target queries resolve existing connections, never caller-supplied source
+//! IDs. A remembered receipt, Profile or shared client is not authority; transport
+//! failure never means standalone.
 //!
-//! Supported cooperative boundaries are Feature activation, ordinary Worker
-//! delegation, Ticket creation (Tool/native WIP/typed service), Workdir filesystem
-//! read/write and whole-attachment command execution, and scoped result notify.
-//! Workdir providers still enforce resolved paths, traversal, capability, Ticket
-//! and provider ceilings. The returned scope is for provider narrowing, not a
-//! transferable credential. Scoped checkout/overlap operations are refused until
-//! their complete access semantics are adapted. Other Feature operations retain
-//! their existing owner checks; they do not automatically acquire this operation
-//! policy. Missing calls are trusted Feature bugs, not interception by a universal
-//! Tool executor or protection against malicious Feature code. Connection tests
-//! must exercise each exposed surface, assert a genuine permitted effect and
-//! assert zero downstream calls on denial, including revocation and provider denial.
+//! Workspace permissions cover collection operations only, not individual resources
+//! of another kind. Exact names never imply dotted descendants. Legacy Feature and
+//! Workspace grants retain their wire representation and exact meaning; reading saved
+//! policy/grants does not issue permissions for newly protected operations/resources.
+//! Non-MCP Feature grants remain inert; no schema rewrite or baseline grants are needed.
+//!
+//! Authorization composes with provider checks: ownership, resolved paths, capabilities,
+//! Ticket actor conditions, observation/CAS, review capability, immutable Job batch and
+//! attempt/writer fences remain mandatory. Queries use identity metadata, not protected
+//! bodies, and do not certify existence. Missing targets are still refused by providers.
+//! Connection tests observe permitted real work and zero downstream work on refusal,
+//! including revocation. Missing calls are trusted Feature bugs, not interception by a
+//! universal Tool executor or a sandbox for malicious Feature code.
