Summary

  • vendor tinyjevclient and update agent-desktop to current main
  • add confidential ResolveIntent and RunGoal members backed by a native Rust Jev loop
  • receive Jev provider configuration and the API key only through TinyBus sensitive module initialization or reinitialization
  • move every runnable example into the tinydesktop-examples crate and add an attested OpenRouter/Spotify live verifier

Dependencies

Public API / behavior

  • contract version moves from 1.0 to 1.1
  • member count moves from 54 to 56
  • ResolveIntent and RunGoal require confidential TinyBus calls
  • the API key is absent from the public member surface and can be rotated through sensitive ReinitializeModule
  • existing field values are withheld from Jev by default; destructive actions always stop for confirmation

Validation

  • cargo fmt --all -- --check
  • cargo clippy --all-targets --all-features -- -D warnings
  • cargo build --all-targets --all-features
  • cargo test --all-features
  • RUSTDOCFLAGS=-D warnings cargo doc --no-deps --all-features
  • per-file coverage gate: all measured production files >= 90%
  • real dynamic loader: 56 members verified
  • live macOS Spotify/OpenRouter run through sensitive reinitialization: Done, one action, playback verified by a fresh Pause control snapshot

Live result

OpenRouter resolved jev-latest to typesafe/jev-1.13-20260917; the final run used 2 calls/attempts and 1.281s provider latency. No API key or screen value was logged.

📝 Walkthrough

Walkthrough

The TinyBus contract adds four confidential Jev methods and associated request and result types. The desktop module adds screen observation, decision gating, intent resolution, and bounded goal execution. Examples move to a separate package, with workspace, CI, release, and documentation updates.

Changes

Jev desktop control

Layer / File(s) Summary
Jev wire contract and member surface

Adds Jev request, decision, and result types; four confidential method names; and contract version 1.1. Updates member counts and documents the Jev control contract.
Screen observation and decision policy
crates/tinydesktop/src/agentic/screen.rs, crates/tinydesktop/src/agentic/policy.rs, crates/tinydesktop/src/agentic/test.rs
Parses accessibility snapshots into screen candidates, builds evaluation requests, selects available targets, and gates decisions using confidence and evidence.
Jev execution and TinyBus integration
crates/tinydesktop/src/agentic/mod.rs, crates/tinydesktop/src/agentic/test.rs, crates/tinydesktop/Cargo.toml
Configures provider clients, resolves intents, and runs bounded goal loops. Tests cover execution, limits, reranking, and provider errors.
TinyBus configuration and method dispatch
crates/tinydesktop/src/tinybus_module/*, crates/tinydesktop/src/desktop/test.rs
Stores and clears the Jev runtime and dispatches four confidential methods. Tests check confidential delivery and behavior after clearing the configuration.

Merge Risk: 🟡 Moderate · up to 6165b

The new Jev goal loop can lose the record of actions already taken on the desktop when a later action fails. It can also exceed the caller's model-call cap, and it may act on a similarly named wrong element with lower confidence. The unconfigured state reaches hosts as a transport failure instead of a normal error response. These issues should be fixed or explicitly accepted before merge.

A rabbit maps the screen with care,
Then weighs each action, choice, and ref.
“I’ll hop through goals, but stop when stalled;
No secret key shall leave its den.”
The examples run, and carrots cheer!

Update the Project Structure tree for the new tinydesktop-examples crate.

The tree still shows examples/ under crates/tinydesktop/. It does not list crates/tinydesktop-examples/. This PR moved the examples, and lines 146-147 already point to -p tinydesktop-examples --bin .... Agents that read this tree will look in a directory that no longer holds the examples.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Update the stale usage string in arguments().

This PR moved the example to the tinydesktop-examples package as a binary. The usage error still prints cargo run --example verify_github_release, and that command now fails. Line 6 of the module docs already shows the correct command.

🐛 Proposed fix
-    let usage = "usage: cargo run --example verify_github_release -- \
-                 <release-tag-url> <archive-name> <sha256>";

Inline comments:
In `@crates/tinydesktop/src/agentic/mod.rs`:
- Around line 139-141: Update the loop in `run_response` to pass the remaining
model-call budget into `resolve_on_screen`, and skip `rerank` when only one call
remains. Ensure each run never exceeds `RunGoalRequest::max_model_calls`,
including when the main request and rerank would otherwise both run.
- Around line 357-367: Update resolve_on_screen so a failed execute_operation
response is returned as a failed decision outcome rather than a raw envelope
error, preserving the decision for the caller. In run_goal_with, map that
outcome to run_response with JevStopReason::ActionFailed, the accumulated turns
and metrics, and the failed decision; keep the ResolveIntent envelope-error path
explicit.

In `@crates/tinydesktop/src/agentic/policy.rs`:
- Around line 314-315: Update the accessible-name matching expression in the
relevant policy function to match normalized names only at word boundaries, so
names like “Liked Songs” do not match “unliked songs.” Preserve the existing
minimum two-word requirement and use the normalized goal and name for the
boundary-aware match.

In `@crates/tinydesktop/src/tinybus_module/dispatch.rs`:
- Around line 417-423: Update jev_runtime to represent missing Jev configuration
without returning a TinyBusError, while keeping lock-poisoning errors unchanged;
in resolve_intent and run_goal, return a DesktopResponse error with code
JEV_NOT_CONFIGURED and the appropriate command name, and update the
corresponding test assertion.

In `@docs/specs/desktop-module-contract.md`:
- Around line 37-49: Update the Members section of the desktop module contract
to list `ClearJev` among members that take no argument, and change the stale
contract version reference from 1.0 to 1.1. Leave the Jev control section
unchanged.

In `@README.md`:
- Line 71: Update the README member count from fifty-four to fifty-eight to
match the listed methods, and correct the layout tree so `tinydesktop/` is a
non-final sibling of `tinydesktop-examples/`, which remains the final branch.
