New references (loaded on demand, one topic each):
- packers.md: reading the shell's rejection signal, distinguishing self-inflicted
failures from genuine refusals, mapping the validation boundary via single-variable
tests, component-type rules (providers vs activities), picking a native host
- framework-runtimes.md: identifying Flutter/RN/Unity/Cordova, the wrong-layer trap,
how to tell which layer draws a given UI before committing to a patch direction
- native-and-so.md: host-library selection criteria, DT_NEEDED does-not-call-JNI_OnLoad,
relocation vs page-permission constraints and relocation-free bootstrapping,
replacing Java methods from native code with trampolines and fail-safe guards
- long-task-discipline.md: live record structure, conclusion grading, drift checkpoints,
handover contents, and the opposite failure of over-documenting
Pitfalls: +P18 install reported success but the build was never installed,
+P19 internal signal substituted for the user-visible outcome,
+P20 not-captured treated as not-present, +P21 two changes then attributing the result,
+P22 waiting on something that needs a human to advance.
SKILL.md: index the new references; add a runtime check for layer ownership to Q3;
add long-task rule; strengthen the verify step; add three hard constraints
(user-visible definition of done, no route discarded on compound evidence,
prove the device changed before measuring).
No app names, package names, or sample-specific identifiers anywhere.
