Every finding cites the file and line it rests on. The full report also covers the team and asks the questions the code cannot answer.

What the repository says
- Releases are cut from another branch than the one surveyed
.github/pull_request_template.md:7: states a policy on AI-generated contributions
Architecture & Codebase — including AI provenance
strongAnkiDroid/src/main/java/com/ichi2/anki/AbstractFlashcardViewer.kt is 2,899 lines, 36× this codebase's median file
adequateThe median source file here is 79 lines. 10 files exceed 1,000 lines, the largest being 2,899. Size is not a defect on its own — some problems genuinely live in one place — but these are where merge conflicts, review fatigue and single-owner knowledge concentrate, and they are the first thing that slows an inheriting engineer down.
AnkiDroid/src/main/java/com/ichi2/anki/AbstractFlashcardViewer.kt:1 — 2,899 lines (36× median) |
AnkiDroid/src/main/java/com/ichi2/anki/NoteEditorFragment.kt:1 — 2,825 lines (35× median) |

Engineering Process & SDLC Maturity
strongNo finding.
Product & Engineering Maturity
strongReleases are cut from another branch than the one surveyed
adequateThe newest release, v2.25.0, is not on the branch this survey read; the newest release on it is v2.24.0. The shipped product may differ from what this report describes. Survey the release branch too.
| tag v2.25.0 |
Security & Reliability Posture
adequateThe app allows plain HTTP to any server
adequateThe app's manifest allows unencrypted HTTP app-wide (NSAllowsArbitraryLoads, or cleartext traffic permitted), rather than for named domains. Anything sent over plain HTTP can be read on the network, and enterprise security reviews ask about it. Some apps need it by nature (a podcast or feed reader fetches whatever URL a feed gives), so ask which case this is.
AnkiDroid/src/main/AndroidManifest.xml:98 — cleartext allowed app-wide |
AnkiDroid/src/main/res/xml/network_security_config.xml:3 — cleartext allowed app-wide |
