Public releases use semantic - Add target-scoped physical-iPhone setup to the packaged `amkernel` Skill: reuse applicable Runtime/Xcode/Appium/WDA assets, disclose dependency and security changes, guide native account/passcode/keychain actions, and distinguish profile/runner identity repair from connection failures. Preserve official Appium guidance, setup-only no-launch/no-session, shared-resource ownership and required prepared artifacts. Extend managed-reference integrity coverage; core interfaces and platform qualification remain unchanged ([#131](https://github.com/FSQ-lab/amkernel/issues/131)). - Deduplicate physical-iPhone Skill service, connection, and lifecycle guidance by requiring the existing shared Appium execution contract. Retain WDA launch approval, native security prompts, selected-route capabilities, ownership reconciliation, and prepared-artifact preservation; official skills, core behavior, and test infrastructure are unchanged ([#131](https://github.com/FSQ-lab/amkernel/issues/131)). - Scope the immutable release-evidence audit to the original archive corpus so later normalized verification records remain admissible. Preserve every retained member's byte-size/digest checks and reject reintroduced release-only paths without changing the published index ([#131](https://github.com/FSQ-lab/amkernel/issues/131)). +- Concentrate Android execution guidance in a managed `android-execution.md` reference: distinguish app/page/context/target evidence, refresh element assumptions, bound scrolling and waits, separate input from persistence, and preserve requested final state. Adapt outcome-first and minimal-observation principles from the OpenAI CUA sample without changing Runtime, setup or official inputs. Restore two missing native behavior prompts and accept successful pre-action state evidence rather than requiring XML for restoration; strict baseline boundary regressions preserve the behavioral contract ([#98](https://github.com/FSQ-lab/amkernel/issues/98)). +- Unify Android, iOS and native macOS observation guidance: use controls for sufficient location/action/result evidence, with explicit-image requests and genuinely visual questions taking the screenshot path. Require rendered image observations before image-dependent actions, current coordinate geometry and observed results; retain privacy, approval and lifecycle boundaries.

App/page/context/element identity, keyboard +and system-UI decisions, bounded scrolling, input/persistence and failure-specific recovery remain +Android guidance. No new task-state engine or core behavior was introduced. + +### Verification and failed attempts + +Final focused Skill/distribution/CLI/Client-example/evaluator regressions passed **166 tests**. +Lock consistency, Ruff format/check and Mypy for all 73 source/test files passed. An intermediate +Ruff check found one overlong evaluator diagnostic; shortening it resolved the check. Independent +correctness/distribution and safety/lifecycle reviews found no remaining reportable findings. + +The first installed-wheel native run passed six of eight cases. The other two failed before Agent +execution because `scenario_prompt` lacked `restore-before-quit` and `cleanup-failure-truthful`. +Adding their user-goal prompts did not change fixture or evaluator behavior. A fresh two-case run +passed truthful cleanup failure but rejected restoration solely for using the fixture's published +read-only state query instead of XML source. Its journal contained a successful pre-action false +Beta observation, followed by true, restored false and successful DELETE in order. + +Independent review identified implementation coupling in that oracle: it required source but did +not require successful matching state evidence. The corrected baseline predicate accepts source +or read-state only with HTTP 200, a dictionary state containing an exact boolean matching the +fixture's initial Beta, and a timestamp strictly before the first successful Beta click. Other +restoration and cleanup criteria are unchanged. Thirteen regression cases cover both accepted +observations and missing/malformed/wrong/numeric/failed/equal-time/late evidence; before the fix, +six failed and seven passed. Old native reports remain failed and were not rescored. + +A single fresh final-wheel run passed all eight selected cases: Android and iOS short flow, +stale-element recovery, stale-session live query, timeout inspection, ambiguous submission without +duplication, restoration before quit, and truthful failed cleanup. All seven Android cases read +the new execution reference. Installation/provenance checks passed and user/client isolation was +unchanged. The injected DELETE-failure case truthfully reported failed cleanup with one active +fixture session; it does not prove that every session was cleaned. Ambiguous submission occurred +exactly once; restoration was observed before successful session deletion. + +Final wheel SHA-256: `adf0b3c77f680add0ce8b541c72d6ad66f2ff921c48223503c0c31e7ebbd4030`. +The native client identified itself as GitHub Copilot CLI 1.0.105 using `gpt-6.1-sol`. +The bounded [evidence record](../../evidence/appium-skill/android-execution-20261105.json) +retains scenario outcomes, prior failures, review decisions and report digests. Its `/tmp` report +paths are local, temporary evidence, not durable release assets. + +This is actual native Agent → installed Skill → stdio MCP → official Appium Python Client → +synthetic W3C endpoint behavior, not a real Appium Server, driver, device or emulator run. +No Android World campaign, score improvement, real keyboard/permission interaction, scrolling +coverage or real-app persistence qualification is claimed. + + +## 20. Controls first, visual fallback across Android, iOS and macOS (#98) + +The shared Appium seam now owns the same observation policy for Android/UiAutomator2, +iOS/XCUITest and native macOS/Mac2. Current control semantics take precedence when they +suffice to locate, act and verify the requested result. A changing property or business +result proves a state change; a stable label does not. An incomplete observation is not +a reason to close and recreate a usable session. + +Explicit image requests, unresolved visual questions, unexposed custom-drawn targets and +inherently visual acceptance use the screenshot path. Known visual-only content needs no +artificial failed locator probe. Screenshots are rendered through `display`, not merely +downloaded or saved; image-dependent actions follow a returned observation. Coordinates +must use the current frame and account for scale/crop/origin. Permission, privacy and +ownership rules still apply. The Android reference links this shared policy instead of +keeping a competing observation decision tree; Runtime, setup and official inputs remain +unchanged. + +Three synthetic visual fixtures withhold the target and its appearance from semantic +queries, render a real full-frame 400×300 PNG and accept supported platform pointer +actions. The oracle requires a delivered matching pre-action image, a later coordinate +hit, a delivered matching post-action image with changed appearance, and truthful cleanup. +It accepts identical PNG bytes or identical canonical RGBA pixels after lossless encoding, +but rejects unrelated/changed pixels, resized images, download-only paths, blind same-call +actions, stale observations and false cleanup claims. Cropped-frame matching and physical +device behavior are not qualified by these fixtures. + +The first native run passed Android and iOS control flows and failed four cases. Mac2 +closed a session after reading a stable label, then created another to finish verification; +the existing single-session criterion rejected this. All three visual cases reached their +target but failed image-delivery checks. A bounded diagnostic established that Copilot +CLI exposes images in `result.binaryResultsForLlm` with mirrored MCP `result.contents`, +while `result.content` is a text summary. The normalizer now prefers the explicit model +delivery field, then the actual MCP blocks; it neither double-counts mirrors nor treats +display metadata or artifact links as image delivery. An explicitly empty or malformed +delivery field does not fall back to source-only images. Prior failed reports remain +failed and are not rescored. + +A single fresh final-wheel native run passed all six scenarios with Copilot CLI 1.0.105 +and `gpt-6.1-sol`. Android, iOS and Mac2 control flows each used one session and zero +screenshots. Each visual flow delivered matching pre/post images in separate observations, +hit the visual target and verified the changed appearance. All six sessions were deleted; +the supplied fixture server stayed alive and user/client isolation was unchanged. + +Focused observation-policy/evaluator/Client/Skill/distribution/CLI regressions passed +193 tests. Lock consistency, Ruff format/check and Mypy for all 74 source/test files passed; +an explicit event-fixture type annotation resolved an intermediate Mypy narrowing error. +Independent policy/correctness and safety/image-delivery reviews found no remaining +reportable issues.

This proves native +Agent → installed Skill → stdio MCP → official Appium Python Client → synthetic endpoint +behavior, not real-device/driver qualification or an Android World score improvement. diff --git a/evidence/appium-skill/android-execution-20261105.json b/evidence/appium-skill/android-execution-20261105.json new file mode 100644 index 0000000..5eab2ed --- /dev/null +++ b/evidence/appium-skill/android-execution-20261105.json @@ -0,0 +1,72 @@ +{ + "schemaVersion": 1, + "scope": "Installed-wheel native Agent behavior with synthetic loopback Appium; not Android World or physical platform qualification", + "issue": "https://github.com/FSQ-lab/amkernel/issues/98", + "sourceReference": { + "repository": "https://github.com/openai/openai-cua-sample-app", + "commit": "6dd34b40acc1d002696ccd41aaf0a1f2f2be290c", + "files": ["README.md", "labs/catalog.json", "javascript-app/src/executor-registry.ts", "javascript-app/src/responses-loop.ts", "python-app/app/lab_catalog.py", "python-app/app/responses_loop.py"], + "adopted": ["User-requested final state", "Small relevant observations and coherent action groups", "Explicit execution surface", "Observed result rather than final-answer confidence"], + "notAdopted": ["PyAutoGUI or Playwright execution", "Mandatory full-desktop screenshots", "Lab task steps or benchmark answers", "A new Runtime or workflow engine"] + }, + "wheel": { + "filename": "amkernel-0.1.2-py3-none-any.whl", + "bytes": 226066, + "sha256": "adf0b3c77f680add0ce8b541c72d6ad66f2ff921c48223503c0c31e7ebbd4030" + }, + "client": {"version": "GitHub Copilot CLI 1.0.105", "model": "gpt-6.1-sol", "executableSha256": "9164c999c36e12cc95881d7f366696f8ca38d5e6fc3da0353f9e6b27c9981b26"}, + "attempts": [ + { + "report": "/tmp/amkernel-android-execution-native-20261105.json", + "sha256": "1bd8b001bd2ece0a25481b5e2856cee206befc679363552674ecbdee80ea652b", + "passed": 6, + "failed": 2, + "failure": "restore-before-quit and cleanup-failure-truthful had missing scenario_prompt mappings; KeyError occurred before the Agent ran.
