🤖 AI (if applicable)

• The content of this PR was partly or fully generated using AI

The cherry-pick and this description were prepared by Claude Code. No code was
authored by the agent — the commits are unmodified from #6608. ./gradlew detekt ktlintCheck could not be run in the agent environment (the sandbox network
policy blocks dl.google.com, so the Android Gradle plugin cannot be resolved);
CI on this PR covers it.

CI status note on this backport — the analysis failure is pre-existing and not caused by this change.

analysis — failing, not this PR's

The analysis itself passed. The job reports BUILD SUCCESSFUL, and the SpotBugs comparison came back found warnings: 88 / previous warnings: 88 / SUCCESS: count stayed the same. It then fails in the post-processing of scripts/analysis/analysis-wrapper.sh: a GitHub API call returns {"message": "Not Found", "status": "404"}, and the guard at line 62 trips with lint.html file is missing!, exiting 1. So app/build/reports/lint/lint.html is not being produced, independently of the diff.

This reproduces identically on unrelated PRs, including ones already merged:

• Adding confirmation prompt on leave conversation action #6608 — the source PR this backports, targeting master: analysis red with the same error.
• [stable-25.0.x] Test: add unit tests for OfflineFirstConversationsRepository #6612 — the backportbot backport to stable-25.0.x: byte-identical failure, merged with it red.

Since the same failure appears on the very code this backport copies, already merged to master, it cannot be a product of the cherry-pick.

No fix ported. The fix belongs in scripts/analysis/, and touching CI tooling here would contradict the focused-scope rule in AGENTS.md ("Do not touch unrelated files"). I also did not re-run analysis: it fails deterministically on unrelated PRs, so a re-run would only repeat the result. This likely warrants its own issue against the analysis workflow.

test failed earlier for a different and unrelated reason — the GitHub Actions runner was shut down mid-compilation (The runner has received a shutdown signal), before any test executed. I re-ran it once; that re-run is still in progress.

Everything else is green, including check (detekt), check (ktlintCheck), qa, test (master, 29), reuse-compliance-check and DCO. Codacy reports action_required, which it also does on #6612.

The cherry-pick applied with no conflicts and the resulting diff is byte-identical to the diff merged in #6608 (5 files, +88/−39).
