* refactor(android): extract adb executor and IME cluster into packages/platform-android (#2041)
Implementation moves behind an injected adb host port (R13-clean); shared
vocabulary moves to contracts (android-touch-plan, android-helper-artifacts)
and kernel (keyed-lock); root keeps thin re-export shims plus the composition
wiring that binds the port. session.ts/session-observability.ts no longer
import platform transport types (opaque unknown, R62 pattern).
* refactor(android): trim shims to consumed surface, break helper-install cycle, add gate coverage
Fallow-clean: shim re-exports carry only names root still consumes;
helper-package-install imports the package subpath directly (no cycle) and
reuses the contracts decision types; transitional R13 table gets planted-red
tests; ADR-0019 records the transitional exception; eager-closure rows added
for the new entry surfaces.
* review: restore maxBuffer on spawn options, scope the transitional test allowance
Adversarial review round 1: AndroidAdbSpawnOptions keeps maxBuffer for spawn-
signature width parity with the pre-move ExecBackgroundOptions; the R13 test
allowance narrows from any test file to the cluster's own src/platforms/android
__tests__ directory, with planted-red coverage for a foreign test file; ADR
text records the scoped allowance.
* review: keep an unbound adb host port loud in listAndroidAdbSerialsQuick
* style: format policy test
* refactor(android): split the extracted adb and IME modules into focused owners
Review: the moved adb-executor.ts (652 lines) and ime-lifecycle.ts (487 lines)
carried three concerns each across the package boundary. The entry subpaths are
now thin surfaces over focused modules — adb: transport vocabulary, failure
classification+enrichment, provider normalization, provider scope/routing,
port-reverse ownership, pull/install transfers; IME: ownership state, on-device
settings record, activation transaction, restore+orphan recovery — every module
under 250 lines, each with colocated tests over an in-memory host-port stub and
a shared fake IME device. R31's fence invariant repoints to ime-activation.ts;
eager-closure pins move to the split shape.
* rebase: reconcile the transitional android table with the #2050 mechanics-facet model
The R13 declaration check now composes both enumerated subpath sets on the
exact-list model #2050 introduced; the policy test fixture declares android's
transitional subpaths the same way it declares apple's runner facet.
