− For iOS App Store screenshots and derived marketing materials, read [apps/ios/docs/marketing-screenshots.md](apps/ios/docs/marketing-screenshots.md).− For approved store-card design and independent processing of existing iOS/Android screenshots, read [docs/store-screenshot-processing.md](docs/store-screenshot-processing.md). Keep this processing flow separate from native capture and store upload; source PNGs are read-only and derived cards belong in the adjacent output folders.− Marketing attribution links and campaign naming rules live in [docs/marketing-links.md](docs/marketing-links.md).− The platform READMEs are part of the working agreement for client work: [apps/web/README.md](apps/web/README.md) for web changes, [apps/ios/README.md](apps/ios/README.md) for iOS and Mac Catalyst changes, and [apps/android/README.md](apps/android/README.md) for Android changes.− We do not try to cover the whole product with tests, and we do not optimize for blanket test coverage metrics.− Do not add unit tests by default, and do not guard every helper or pure function with a dedicated test.− Do not add new unit tests for this repository as part of implementation or as part of a written plan unless the user explicitly asks for unit tests.− The most trusted tests are the native/browser smoke flows that run the real app on a simulator, emulator, managed device, or deployed environment because they are the closest checks to production behavior.− Keep tests minimal and focused on primary user flows, critical contracts, or important cross-module behavior.− When proposing a test plan, treat "real testing" as one of these two options only: either implement a real integration/end-to-end/smoke flow that exercises the app or API for real, or provide explicit manual test instructions for the user to run. Do not treat unit tests as the default validation plan.− Local Gradle, `xcodebuild`, simulator, and emulator runs are unrestricted, so run them whenever they are useful without asking the user for approval.− For every manual or automated Apple test, local or cloud, including Release/TestFlight, set `FLASHCARDS_AUTOMATION_RUN=1` in the app process and verify `automation_run_decided` reports `isAutomation=true` before interacting; on Mac, launch with `bash scripts/ios/launch-macos-test-app.sh "<path/Nibomo.app>"`.− Release and check workflows use independent AWS/web, Android, and iOS streams.− Android jobs inside `.github/workflows/pr-checks.yml` are an accepted exception: build, unit tests, and lint run for every Android-impacting pull request, and the GitHub-hosted `data:local` emulator instrumentation runs only when the Android data layer or shared Android Gradle configuration changes. `Repository static checks` is the strict required aggregate PR gate; Device Run stays out of pull requests.− Infra-changing pull requests synthesize the CDK app and fail at 470 resources per stack, 30 below CloudFormation's hard limit.− Auto-merge is enabled but never updates a `BEHIND` branch, so it cannot rescue a pull request on its own: update the branch once server-side, then queue `gh pr merge --auto` so the merge lands unattended once the gate passes instead of racing `main` with repeated updates, and still watch the post-merge deploy to completion.− Nothing compiles iOS before merge by design, though `PR Checks` still runs the static iOS checks.− Run Apple builds and tests only in Xcode Cloud or local Xcode; never use Firebase for Apple tests. Xcode Cloud workflow definitions live in App Store Connect; its in-repo build inputs are documented in [docs/ios-ci-cd.md](docs/ios-ci-cd.md).− Keep the Xcode Cloud `Test - iOS` action non-required on purpose so TestFlight can receive builds even when smoke tests fail.− For Android releases, run device tests in Device Run and use the existing `Android Release` workflow and GitHub Actions signing secrets described in [docs/android-ci-cd.md](docs/android-ci-cd.md). A missing local upload key does not block CI signing and is not grounds for key reset or recovery. Inspect the workflow run and all four exact Device Run sessions and named test results under the [Android release procedure](docs/release/android.md#android).− Details, rollback rules, and live smoke references: [docs/release-gates.md](docs/release-gates.md).− ## Repository Strategy− Use a single monorepo for now because it keeps shared API contracts and the data model together, makes coordinated backend/mobile changes easier, and lowers operational overhead at this stage.− - Source of truth: Postgres in AWS− - Mobile local database: SQLite on device− - Sync model: offline-first synchronization via API− ## Database Decision− Use Postgres as the primary backend database because flashcards data is relational (workspaces, cards, review events, sync metadata), transactions/consistency matter, and schema/query evolution for scheduling, stats, and filtering is simpler than with DynamoDB as primary.− ## Offline-First Sync Rules− - Read and write locally to SQLite first.− - Queue local writes in an `outbox`.− - When connectivity returns:−   1. push pending operations to the backend (idempotent by operation id)−   2. pull remote changes since the last sync cursor−   3. apply updates locally−   4. advance the sync cursor and clear acknowledged outbox rows− The sync approach and the data model changed multiple times during development. To understand how the system works now, read `docs/architecture.md` together with the full relevant migration chain in `db/migrations`, and do not infer current behavior from only one or two isolated migrations.− ## Planned Monorepo Shape− `apps/{backend,ios,android}`, `db/{migrations,views,queries}`, `infra/{docker,aws}`, `docs/`, `scripts/`− ## Auth Service (`apps/auth/`)+ Before marketing or store-asset work, read the matching guide: [iOS App Store screenshots](apps/ios/docs/marketing-screenshots.md), [store-card processing](docs/store-screenshot-processing.md), or [attribution links and campaign naming](docs/marketing-links.md).+ Before changing auth (`apps/auth/`, passwordless email OTP via AWS Cognito), read [docs/auth-service.md](docs/auth-service.md).+ Before changing card reappearance or FSRS scheduling, read [docs/fsrs-scheduling-logic.md](docs/fsrs-scheduling-logic.md).+ We do not optimize for blanket test coverage. Do not add unit tests, in an implementation or a written plan, unless the user explicitly asks for them.+ The most trusted tests are the native/browser smoke flows that run the real app on a simulator, emulator, managed device, or deployed environment. Keep tests minimal and focused on primary user flows, critical contracts, or important cross-module behavior.+ A test plan offers only real testing: a real integration/end-to-end/smoke flow that exercises the app or API, or explicit manual test instructions for the user.+ Run useful local project checks, builds and tests during implementation and pre-release validation without additional approval. Honor explicit static-only review instructions. AWS deployment and deployment-artifact restrictions above still apply.+ Before every manual or automated Apple test, local or cloud, including Release/TestFlight, apply the [automation marker](docs/ios-ci-cd.md#automation-marker).+ ## Local development loop+ Rule: read production, write locally. Both commands open on `localhost` without login; check admin and web changes there before merge.+ - `make local-admin`: the admin app on `http://localhost:3001` reading production data read-only through `reporting_readonly`; details in [apps/admin/README.md](apps/admin/README.md#local-admin-on-production-data-read-only).+ - `make local-app`: the web app on `http://localhost:3000` against a local Docker Postgres, never production; details in [apps/web/README.md](apps/web/README.md#local-login-free-stack).+ Before merging a pull request, read [merging pull requests](docs/release-gates.md#merging-pull-requests).+ Run Apple builds and tests only in Xcode Cloud or local Xcode; never use Firebase for Apple tests.+ Release streams, Apple and Android release gates, rollback rules, and live smoke references: [docs/release-gates.md](docs/release-gates.md).+ Before any product-data analysis, read [docs/analytics-db-access.md](docs/analytics-db-access.md).+ Postgres in AWS is the source of truth. Clients read and write their local store first, queue writes in an outbox, and sync through the API.+ The sync approach and the data model changed multiple times during development. To understand how the system works now, read [docs/architecture.md](docs/architecture.md) together with the full relevant migration chain in `db/migrations`, and do not infer current behavior from only one or two isolated migrations.+ - Store each fact once: in code; if code cannot say it, in the shortest comment beside the code that enforces it; only short high-level information no code can hold (how parts combine, product and business decisions, procedures a human runs) goes in `docs/`, once. Everything else links to it, and a repeat needs a reason. Marketing and published content (store and connector listings, website articles) is content, not code documentation, and is exempt.+ - The in-app chat and the MCP server serve one tool inventory from a shared registry, and the Agent REST API re-implements the same capabilities as HTTP routes over the same shared contract modules; before changing any of those three surfaces or any AI-facing text (MCP instructions, tool descriptions, guides, chat prompt), read [docs/agent-tool-surfaces.md](docs/agent-tool-surfaces.md).+ - Use separate native screens for mobile forms and multistep flows, replacing the previous step instead of expanding controls beneath it.+ - In every client UI, every user tap should trigger immediate platform-standard UI feedback, with background loading shown in place or on the next surface, failed actions restoring the previous state, and successful actions clearly exposing the next step.

− Before releasing or bumping versions, read [Release All Platforms and Start the Next Development Version](docs/release-current-version.md); it owns the release sequence, authorization, and aligned version surfaces.− Android jobs inside `.github/workflows/pr-checks.yml` are an accepted exception: build, unit tests, and lint run for every Android-impacting pull request, and the GitHub-hosted `data:local` emulator instrumentation runs only when the Android data layer or shared Android Gradle configuration changes. `Repository static checks` is the strict required aggregate PR gate; Firebase Test Lab stays out of pull requests.− Swift builds and tests run in Xcode Cloud, whose workflow definitions live in App Store Connect; its in-repo build inputs are documented in [docs/ios-ci-cd.md](docs/ios-ci-cd.md).− - Errors and crashes: Sentry, one project per surface (`SENTRY_BACKEND_PROJECT`, `SENTRY_WEB_PROJECT`, `SENTRY_ANDROID_PROJECT`, `SENTRY_IOS_PROJECT`) inside `SENTRY_ORG`. When resolving a fixed Sentry issue, default to `Resolved in current release` for backend/web/MCP and `Resolved in next release` for iOS/Android; use the actual shipped release when known. iOS `WatchdogTermination` events carry no stack trace by design; read [docs/ios-memory-diagnostics.md](docs/ios-memory-diagnostics.md) befo− - When adding, removing, or renaming backend HTTP routes, update `infra/aws/lib/gateways/api-gateway.ts` in the same change so API Gateway stays in sync.− Backend changes must remain backward-compatible with already released client versions by default. Do not break backend-facing contracts or behavior that shipped clients rely on unless the user explicitly asks for a breaking change. For the web, iOS, and Android clients, backward compatibility is not a goal; prefer keeping the latest codepath clean and current.+ Before releasing or bumping versions, read [Release All Platforms](docs/release/README.md); it owns the release sequence, authorization, and aligned version surfaces.+ ## Mobile OS Compatibility+ - Prioritize the latest mobile OS: native UX, performance, current dependencies, and clean architecture.+ - Support older OS versions through narrow availability/API adapters; share domain logic, state, storage, sync, and navigation across OS versions within each mobile app. Do not duplicate screens or downgrade the architecture for older devices.+ Run the full existing mobile smoke selection on the latest OS; run only a small essential compatibility smoke on older supported OS versions.+ Android jobs inside `.github/workflows/pr-checks.yml` are an accepted exception: build, unit tests, and lint run for every Android-impacting pull request, and the GitHub-hosted `data:local` emulator instrumentation runs only when the Android data layer or shared Android Gradle configuration changes. `Repository static checks` is the strict required aggregate PR gate; Device Run stays out of pull requests.+ Infra-changing pull requests synthesize the CDK app and fail at 470 resources per stack, 30 below CloudFormation's hard limit.+ Run Apple builds and tests only in Xcode Cloud or local Xcode; never use Firebase for Apple tests. Xcode Cloud workflow definitions live in App Store Connect; its in-repo build inputs are documented in [docs/ios-ci-cd.md](docs/ios-ci-cd.md).+ For Android releases, run device tests in Device Run and use the existing `Android Release` workflow and GitHub Actions signing secrets described in [docs/android-ci-cd.md](docs/android-ci-cd.md). A missing local upload key does not block CI signing and is not grounds for key reset or recovery. Inspect the workflow run and all four exact Device Run sessions and named test results under the [Android release procedure](docs/release/android.md#android).+ - Errors and crashes: Sentry, one project per surface (`SENTRY_BACKEND_PROJECT`, `SENTRY_WEB_PROJECT`, `SENTRY_ANDROID_PROJECT`, `SENTRY_IOS_PROJECT`) inside `SENTRY_ORG`. Before resolving a fixed Sentry issue, read `$HOME/.agents/skills/sentry-triage-kirill/SKILL.md`. Resolve per project using the exact merged fix commit or verified first fixed Sentry release; never infer it from checked-in semver or platform name, or treat a merge or Sentry release as proof of deployment or public store availa+ - The root `{proxy+}` in `infra/aws/lib/gateways/api-gateway.ts` forwards every backend path, so add a gateway resource for a backend route only when it needs distinct gateway behavior (throttle, CORS origins, integration, auth); every gateway resource, method, and Lambda permission counts toward the stack's 500-resource CloudFormation limit.+ Backend changes must remain backward-compatible with already released client versions by default. Do not break backend-facing contracts or behavior that shipped clients rely on unless the user explicitly asks for a breaking change. For the web, iOS, and Android clients, preserving obsolete client implementations is not a goal; keep the latest codepath clean and current while supporting the mobile OS versions declared in the platform READMEs.
