CI: NDK r28+ and native libs verification

[WRRicht3r]

Summary

Install NDK 28.0.12674087 (default), keep 25.2 for utils. Export NDK env to r28, print revision, and verify native libs via readelf

Type of Change

- [ ] fix (bug fix)
- [ ] refactor (no functional change)
- [x] chore/build (tooling, CI, deps)
- [ ] docs (README/AGENTS, comments)

If UI changes, include before/after.

Test Plan

Commands run locally:
./gradlew detektAll
./gradlew runTest
./gradlew :app:lint
Additional checks and scenarios covered:

• CI installs NDK r28 (default) and r25.2 (compat), prints NDK revision, and runs
  readelf on native libs
• Gradle/AGP versions printed for traceability

Risks & Rollout

Potential impact, migrations, or config/secrets required.

• NDK default changed to r28 in CI; fearless-utils still declares r25.2 (kept
  installed)
• Follow-up PR to bump utils’ ndkVersion to r28+ recommended

Checklist

• Linked an issue and added a clear description
• Added/updated tests for changed code (where applicable)
• Updated docs (README/AGENTS/roadmap) when behavior or commands changed
• Ran detektAll, runTest, and :app:lint locally (or via CI)
• No secrets or local.properties committed

Summary

• Adds printPolkadotSdkAlignment step to GitHub Actions (early in build).
• Switches Jenkins testCmd to postMergeCheck for full validation.
• Adds scripts/post_merge_check.sh for local/CI parity and quicker triage.

Why

• Surface Polkadot SDK alignment and any shared_features pin up front.
• Standardize post‑merge checks: static analysis, unit tests + coverage, assemble,
  lint.
• Provide a single local entrypoint mirroring CI.

What To Look For

• GitHub Actions logs: a step named “Polkadot SDK alignment” with:
  • “Polkadot SDK alignment (effective):”
  • TYPES_URL, DEFAULT_V13_TYPES_URL, CHAINS_URL (debug/release),
    SHARED_FEATURES_VERSION_OVERRIDE
• Jenkins logs: postMergeCheck runs in order:
  • printPolkadotSdkAlignment → runTest → :app:assembleDebug → :app:lint
• Coverage: XML/HTML under coverage/coverage-.*
• Lint: app/build/reports/lint-results-*.html

How To Validate Locally

• Full cycle (mirrors Jenkins task): ./gradlew postMergeCheck --no-daemon
  --console=plain
• Script with extra guards (utils toggle checks):
  • Full: bash scripts/post_merge_check.sh
  • Quick: bash scripts/post_merge_check.sh --unit-only
  • Offline: add --offline if caches are warm
• Expected utils toggle messages (script asserts):
  • When unset: “USE_REMOTE_UTILS not set; using published artifacts for
    fearless-utils”
  • When true: “Including remote fearless-utils from GitHub via sourceControl”

Notes

• No runtime code changes; CI/config only.
• If first run or network‑constrained, set mirrors in local.properties:
  • TYPES_URL_OVERRIDE, DEFAULT_V13_TYPES_URL_OVERRIDE, CHAINS_URL_OVERRIDE
• Optional SDK alignment pin via SHARED_FEATURES_VERSION_OVERRIDE=1.x.y

[WRRicht3r]

Summary

• GitHub Actions: added “Polkadot SDK alignment” step after Gradle version.
• Jenkins: switched testCmd to postMergeCheck for full validation.
• New script: scripts/post_merge_check.sh for local/CI parity.
• Fix: corrected import order in SuccessViewModel.kt to satisfy Kotlin compiler.

Why

• Surface effective Polkadot SDK alignment and any shared_features pin early.
• Standardize post‑merge checks: detekt, unit tests + coverage, assemble, lint.
• Provide a single local entrypoint mirroring CI behavior.

Validation

• Detekt: clean (0 findings). Report: build/reports/detekt/detekt.html|md.
• Unit tests: all sampled modules green (no failures). Reports under */build/reports/
  tests/testDebugUnitTest/.
• Assemble: :app:assembleDebug successful.
• Lint: :app:lint successful.

How Reviewers Can Verify

• Actions logs: find the “Polkadot SDK alignment” step showing:
  • “Polkadot SDK alignment (effective):”
  • TYPES_URL, DEFAULT_V13_TYPES_URL, CHAINS_URL (debug/release),
    SHARED_FEATURES_VERSION_OVERRIDE
• Jenkins: confirm pipeline runs postMergeCheck (alignment → detekt → tests/JaCoCo →
  assemble → lint).
• Local quick run:
  • Full: ./gradlew postMergeCheck --no-daemon --console=plain
  • Script: bash scripts/post_merge_check.sh (use --unit-only or --offline as
    needed)

Notes

• No runtime logic changes; CI/config updates and a minor import‑order fix only.
• If first run or network‑constrained, set mirrors in local.properties:
  • TYPES_URL_OVERRIDE, DEFAULT_V13_TYPES_URL_OVERRIDE, CHAINS_URL_OVERRIDE
• Optional: pin SHARED_FEATURES_VERSION_OVERRIDE=1.x.y to align with a specific SDK
  release.
