…(iosbuild) (androidbuild) - streamr-trackerless-network: :protos over the NetworkRpc trio (global- namespace messages/enums via export using ::X; plugin stubs in streamr::protorpc) + coarse :all over 13 public headers. All 12 test TUs flipped to import with zero fallout. - streamr-libstreamrproxyclient: deliberately NO module — the C header is the permanent ABI; implementation TU stays textual until consolidation (its internal header dies there). 15/15 tests unchanged. - 2 more constants -> inline constexpr. Release gate (2.4 lesson) green. FINAL FACADE-STAGE METRICS (vs 2.0 baseline, recorded in MODERNIZATION.md): clean 102s -> 78s (-24%, target -25%: effectively met); SLogger touch 65s -> 58s; StreamID touch 19s -> 32s (BMI-chain latency — the incremental targets are consolidation work, and the numbers now quantify exactly why). Verified: root 307/307; proxyclient 15/15; full lint; tn Release build+test green. Android smoke gated via PR keyword (first Android build since the dependency wave).

…droid unsupported (iosbuild) (androidbuild) First Android build since the 1.3 dependency wave failed at vcpkg install: the new baseline's folly port excludes android in its supports expression. Pre-existing latent breakage (unrelated to modules), exposed by this phase's Android smoke gate. The monorepo built folly for arm64-android on the old baseline; the overlay re-allows it (JUSTIFICATION.md updated). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…s (iosbuild) (androidbuild) The Android smoke (first since the dependency wave) got all the way through vcpkg deps (folly-on-NDK builds with the relaxed supports) and failed in our code: NDK clang 18/19's modules support is too immature — import streamr.json fails to provide the toJson overload set (known export-using overload bugs, fixed in newer clang). Resolution: STREAMR_MODULES_SUPPORTED=OFF on Android in StreamrModules.cmake. Libraries build textually from headers (which stay the source of truth during the facade stage): streamr_add_module_library falls back to STATIC + stub source so PUBLIC usage stays identical; streamr_target_module_sources/streamr_enable_imports no-op. Test and example targets (which import) are skipped on Android — they are never executed there, and the shipping artifact (proxyclient .so) does not import. Revisit when the NDK ships clang >= 22; consolidation (2.6) requires it, noted in the helper. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Lint is host-independent and already runs on both validate.yml Linux legs and macOS. On an Android build tree the import-using test files are not compiled (tests are skipped on Android — StreamrModules.cmake), so clangd has no compile commands for them and emits spurious diagnostics. The iOS workflow has never linted, for the same reason. The install step (full Android library cross-build incl. folly-on-NDK) remains the Android smoke gate.

The migration surface is complete — every C++ package that exports an API now ships a module.

:protosover the NetworkRpc trio — with a twist:NetworkRpc.protodeclares no package, so the 22 messages + 4 enums live in the global namespace and export via plainexport using ::X;, while the plugin-generated client/server stubs live instreamr::protorpc. Plus the coarse:allpartition over all 13 public headers. All 12 test TUs flipped toimportwith zero fallout — the first package to flip cleanly on the first build.streamrproxyclient.his the permanent public ABI; the implementation TU keeps textual includes until consolidation (its internalLibProxyClientApi.hppdies there anyway, and mixing import with an internal header that reaches every third-party stack would re-trigger the clangd false-ODR issue). Verified unchanged: 15/15 tests.Final façade-stage metrics (vs the Phase 2.0 baselines, in MODERNIZATION.md)
SLogger.hpptouchStreamID.hpptouchHonest reading: the clean-build target is met already at the façade stage. The incremental targets cannot be met by the façade alone — while headers remain the textual source of truth inside
:allGMFs, any header touch invalidates the package BMI and cascades down the module DAG. Consolidation (2.6) — code into partitions, headers deleted — is where the incremental wins come from, and these numbers now quantify exactly why. That's the decision data for the 2.6 review.Platform gates

Phase 2.6: the consolidation decision — with the full measurement story (façade wins + incremental gap) on the table.
