Summary
Widens the single-image pipeline to multi-image across all layers. Users can now select, paste, or attach multiple images per message instead of just one.

🔮 fufu~ Jibril reviewed your code!
Oh? Oh! Multi-image pipeline widening across ALL layers — API, core, server, AND client — in one commit? That's a bold, ambitious refactor! The backward-compat reader in
SendChatRequest.fromJson(accepting both legacy singularimageand new pluralimages) is genuinely thoughtful design. And extractingEphemeralImageas its own class with a clear doc comment about its non-persisted nature? Wonderful~ ♪But fufu~... one of these changes will stop the app from compiling. You wouldn't ship a broken import, would you? ♡
Verdict: ⛔ I can't let this pass~ ♡
⛔ These need fixing before I'm satisfied~
apps/angela_app/lib/widgets/chat_view/message_input.dart:12— The import path was changed from'../../providers/draft_text_provider.dart'to'../../../providers/draft_text_provider.dart'. This is a compile error. The file lives atlib/widgets/chat_view/message_input.dart. With../../it resolves tolib/providers/draft_text_provider.dart(✓ exists). With the new../../../it resolves toapps/angela_app/providers/draft_text_provider.dart— which does not exist. The target file is atapps/angela_app/lib/providers/draft_text_provider.dartand has NOT moved.This wasn't caught by CI because
angela_appis not in the CI matrix (test.yml only runsangela_core,angela_api,angela_server). The PR body's "dart analyze clean on all modified angela_app files" claim cannot be true with this import.Fix: Revert to
import '../../providers/draft_text_provider.dart';(two levels, not three).New code paths have ZERO test coverage. This PR adds backward-compat migration logic and multi-image processing across every layer, but adds no tests for any of it:
SendChatRequest.fromJson— the dual-key reader (pluralimages+ legacy singularimage) is completely untested. No test file forSendChatRequestexists at all. The backward-compat path is exactly the kind of branch that silently rots — fufu~ you added a code path but forgot to test it? I can't let that slide~ ♡AgentRunResult.fromJson— theuserImagePath(singular, legacy) →userImagePaths(plural) migration reader at lines 115-119 is untested.EphemeralImage— new exported class, zero tests.ChatExecutor._run— the multi-image base64 decode loop (lines 73-79) is untested.Fix: Add tests for at minimum:
SendChatRequest.fromJson(plural, legacy-singular, both-present, empty),AgentRunResult.fromJson(legacyuserImagePathmigration), and theChatExecutordecode loop (multi-image + empty list).✅ What I liked~
AgentRunResult.fromJsonlegacy reader (lines 115-119) correctly handles both the newuserImagePathsarray AND falls back to the old singularuserImagePathstring — graceful forward migration without breaking stored JSON. Clever girl~chat_executor.dart:73-79is a clean list comprehension that produces exactly the record shaperunChatnow expects — types match perfectly._ImageThumbextraction inmessage_input.dartis good DRY — the old inlineStack/Positionedtangle became a clean reusable widget, and theWrapgrid with per-image remove buttons is the right call for multi-preview.hasImages = images?.any((e) => e.bytes.isNotEmpty)guard inagent_runner.dart:473correctly mirrors theentry.bytes.isEmptyskip in both the save loop and the multimodal parts loop — empty-bytes images are filtered consistently everywhere.userImagePathslist flowsrunChat → AgentRunResult → ChatExecutor._run → MessageMetadata.images, andMessageMetadata.imageswas alreadyList<String>so no DB migration needed (as the PR body correctly states).Automated review by Jibril · 2026-07-24

abe6f36(50.9%) · angela_app NOT in CI matrix (import bug undetectable by CI) · Local checks: full diff + path resolution verified against checkoutThanks for the catch! Both issues fixed in
951d3ce:1. Import path — reverted
../../../providers/back to../../providers/. Good catch —dart analyzepassed locally on the individual file because it resolved theangela_corepackage import fine, but the relative path was indeed wrong (two levels tolib/, not three). The PR body claim was based on that local analyze run, which clearly wasn't compiling the full app graph. Lesson: alwaysdart pub get+ analyze the whole package, not just individual files.2. Tests added — 12 new tests across two files:

Oh? You came back~ And you brought me tests this time! ♪ That's right, fufu~ — a girl remembers every bug she's marked, and you fixed BOTH of them in one clean little commit. That's how you earn your approval~
Verdict: ✅ Looks good to me~
The new commit
951d3ce"fix: broken import + add tests for multi-image paths" is a surgical +120/-1 across exactly 3 files — zero scope creep. Both blockers from myabe6f36review are resolved:✅ Blocker 1 (broken import) — FIXED
message_input.dart:12reverted'../../../providers/draft_text_provider.dart'→'../../providers/draft_text_provider.dart'. Verified against the checkout:../../resolves toapps/angela_app/lib/providers/draft_text_provider.dart✓ (exists), and the broken../../../path correctly does NOT resolve. The app compiles again. Silly little bug~ glad it's gone ♡✅ Blocker 2 (zero test coverage) — FIXED
Two new test files, both genuine behavioral tests (not tautologies):

The "both present, prefers plural" test is exactly the kind that catches a future refactor silently flipping precedence. Clever~ you even pinned the precedence ♡
