…the IDE and compile daemon share Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Kj9YeCDHGp9DU8LPtfWJ7W
Finding (Important, pr03-review.md): DaemonProtocolDtoTest's first test was named "configure without optional toolchain paths means self-discovery" with a comment calling null the "discover from ANDROID_HOME" signal — the opposite of the contract in the same commit (DaemonProtocol.kt KDoc: "required, as the daemon never guesses a tool path"; README: configure answers ok:false with one diagnostic per missing field) and of the daemon's actual behavior at stack tip (DaemonService.configure rejects null/blank aapt2/d8Jar/androidJar). Fix: renamed the test and rewrote the comment so null reads as "not supplied, and configure rejects it", per the documented contract. The assertions were already correct (null IS the DTO default) and are unchanged; the rejection behavior itself is asserted in the daemon module's DaemonServiceTest at stack tip, so no rejection assertion is duplicated here.

WalkthroughThe PR adds the ChangesQuick Build protocol
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to Failed protocol responses can currently omit an error diagnostic, leaving the IDE or daemon without a usable failure cause; this is a concrete correctness issue that should be fixed before merge. The conflicting documentation for array-valued results also warrants owner follow-up, while the fixture documentation gap is non-blocking. Poem

Correct the response-value type contract.
DaemonResponse.values is documented as JSON-scalar-only, and the README says op values are scalars. The README also defines classesChanged as an array. This conflict can make a peer serialize or parse classesChanged with the wrong type.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Preserve the failure-response error invariant.
failure(id, diagnostics) accepts an empty list or a warnings-only list. It then returns ok = false without an ERROR diagnostic. This violates the DaemonResponse contract and can report a failed operation without an error cause.
Normalize this input with a locationless ERROR diagnostic, or reject invalid diagnostics before constructing the response. Add a regression test for a warnings-only input.
