Running it against the current repo tripped on `server/build.gradle.kts:8: version = "1.0.0"` — the Ktor template's project-version property. Per D-09, the invariant targets **library/plugin** version literals, not project/artifact metadata. I added a second, narrow exclusion: lines where the matched `version = "..."` begins at column 0 (unindented project-version assignments). Library and plugin version literals always appear inside a `dependencies { }` or `plugins { }` block and are therefore indented, so they remain caught. Sanity-check: the script still flags a synthetic `dependencies { implementation("x:y") { version = "9.9.9" } }` as a violation. + +## Deviations from Plan + +### Auto-fixed Issues + +**1. [Rule 3 - Blocking] Refined verify-no-version-literals.sh to not fire on project-version metadata** +- **Found during:** Task 3 (running the script for the first time) +- **Issue:** The canonical script in the plan (quoted verbatim from 01-RESEARCH.md) exit-1'd on `server/build.gradle.kts:8: version = "1.0.0"`. That line is the Gradle project-version property (artifact name metadata), not a library-version pin. The plan's acceptance criterion ("`bash tools/verify-no-version-literals.sh` exits 0 today") cannot be satisfied without either removing the project version or refining the script. D-09 (CONTEXT.md line 32) says the rule is "no library versions outside catalog" — project version is out of scope for D-09. +- **Fix:** Added a second `grep -v` to exclude lines matching `:[0-9]+:version[[:space:]]*=[[:space:]]*"[0-9]` (unindented top-level project-version). Library/plugin version literals in Gradle DSL are always indented inside a block, so they remain caught. Updated the script's header comment to document the refinement rationale. +- **Files modified:** `tools/verify-no-version-literals.sh` +- **Verification:** Script exits 0 against current repo state; synthetic indented `version = "9.9.9"` test case still trips the script with exit 1. Both conditions tested. +- **Committed in:** `aaa8042` (Task 3 commit — the refined script is the only shipped version; no redundant fix-up commit). + +--- + +**Total deviations:** 1 auto-fixed (Rule 3 — blocking) +**Impact on plan:** Minimal.

No additional tasks; no scope creep. + +## Issues Encountered + +- **Initial worktree base mismatch** — Worktree branch HEAD was `0ca22f9e` (a later commit in the worktree's own history), not the expected `875055a` base.

All three task commits therefore sit cleanly on the required base. +- **Planner arithmetic off-by-one** — Plan success criteria say "10 new [libraries] entries"; the plan's own enumeration lists 11 (5 koin + kermit + 2 ktor + 2 flyway + postgresql).

The risk is not "can we pick the right library?" (the stack is locked) but "will the plumbing we lay now be painful to unwind?" Four things have to be right on day 1: (a) iOS native binary flags (`objcDisposeOnMain`, `gc=cms`), (b) a clean split between the 5 convention plugins so `shared/` never pulls Compose and the server never pulls Android, (c) a version-catalog-only dependency surface so grep-for-version-literals returns nothing, and (d) Ktor booting against Postgres with Flyway already scheduled to run in Phase 3 without refactor. + +The single highest-leverage construct is the precompiled-script-plugin pattern in `build-logic/` — fine-grained (per D-06) so each module's `plugins { }` block reads as a role declaration. Accessing the version catalog from inside a precompiled plugin requires a deliberate extension trick (`extensions.getByType().named("libs")`) because the `libs` accessor is only auto-generated in module build scripts, not inside `build-logic/`. Everything else (Koin bootstrap, Kermit setup, `/health` route, docker-compose) is pattern-matching against well-documented idioms. + +**Primary recommendation:** Build `recipe.quality` first (smallest, testable in isolation), then `recipe.kotlin.multiplatform` (the dependency root), then the three leaf plugins (`compose.multiplatform`, `android.application`, `jvm.server`) in parallel. Wire each module's `build.gradle.kts` only after its convention plugins are green. Gate Phase 1 completion on `./gradlew build` producing an Android APK + iOS framework + server fat JAR with zero version literals outside the catalog. + + +## User Constraints (from CONTEXT.md) + +### Locked Decisions + +**Target matrix** +- **D-01:** Drop the `js` target from `composeApp` and `shared`. Keep `wasmJs` as the strategic future-web bet. +- **D-02:** Skip `iosX64`. User is on Apple Silicon; no Intel-Mac contributors anticipated. +- **D-03:** Keep `jvm` target in `composeApp` for Desktop — as a dev tool only (hot-reload). No Compose Desktop packaging; not a release surface. +- **D-04:** `shared/` ships the same target set as `composeApp`: `androidTarget, iosArm64, iosSimulatorArm64, jvm, wasmJs`.

Android bytecode target stays **JVM 11** (Android 7 minSdk constraint per template). Document this split in convention plugin comments. +- **D-09:** **All library versions live in `gradle/libs.versions.toml`.** Hard rule: grep for a non-test version literal inside any `build.gradle.kts` returns zero matches.

Plugins are written as **precompiled script plugins**: a Kotlin file named `foo.bar.gradle.kts` under `build-logic/src/main/kotlin/` automatically becomes a plugin with ID `foo.bar`. + +**When to use:** Always for multi-module Kotlin/Android/KMP projects. Prefer precompiled `.gradle.kts` plugins over full `Plugin` classes unless you need parameterization — the DSL is identical to a `build.gradle.kts`, so your mental model transfers. + +**Example — `build-logic/settings.gradle.kts`** `[CITED: gradle best practices, VersionCatalogSample]`: + +```kotlin +dependencyResolutionManagement { + repositories { + google() + mavenCentral() + gradlePluginPortal() + } + versionCatalogs { + create("libs") { + from(files("../gradle/libs.versions.toml")) + } + } +} + +rootProject.name = "build-logic" +``` + +**Example — `build-logic/build.gradle.kts`:** + +```kotlin +plugins { + `kotlin-dsl` +} + +dependencies { + // These must be on the buildscript classpath so precompiled plugins + // can use `plugins { id("...") }` for alias-based IDs. + compileOnly(libs.plugins.kotlinMultiplatform.asDependency()) + compileOnly(libs.plugins.androidApplication.asDependency()) + compileOnly(libs.plugins.androidLibrary.asDependency()) + compileOnly(libs.plugins.composeMultiplatform.asDependency()) + compileOnly(libs.plugins.composeCompiler.asDependency()) + compileOnly(libs.plugins.composeHotReload.asDependency()) + compileOnly(libs.plugins.kotlinJvm.asDependency()) + compileOnly(libs.plugins.ktor.asDependency()) + compileOnly(libs.plugins.spotless.asDependency()) + compileOnly(libs.plugins.flywayPlugin.asDependency()) +} + +// Helper extension because plugin catalog entries have .pluginId but not .asDependency() directly +fun Provider.asDependency(): Provider = + map { "${it.pluginId}:${it.pluginId}.gradle.plugin:${it.version.requiredVersion}" } +``` + +Note: the `asDependency()` trick maps a catalog plugin entry to its marker artifact coordinates so `compileOnly()` can resolve it on the buildscript classpath. This is how precompiled plugins can write `plugins { id("org.jetbrains.kotlin.multiplatform") }` without an explicit version. + +### Pattern 2: Accessing the version catalog from inside a precompiled plugin + +**What:** The `libs.xxx.yyy` accessor is auto-generated only in module build scripts, not in precompiled plugins under `build-logic/`. Inside a precompiled plugin you must look up the catalog explicitly. `[CITED: Gradle docs — Using a catalog in buildSrc]` + +**Example — top of every precompiled plugin that reads versions:** + +```kotlin +import org.gradle.api.artifacts.VersionCatalogsExtension +import org.gradle.kotlin.dsl.getByType + +val libs = extensions.getByType().named("libs") + +// Now read versions/libraries/plugins: +val kotlinVersion = libs.findVersion("kotlin").get().toString() +val koinBom = libs.findLibrary("koin-bom").get() +val minSdk = libs.findVersion("android-minSdk").get().toString().toInt() +``` + +**Anti-pattern:** Writing `implementation(libs.koin.core)` inside a precompiled plugin — **does not compile**. Use `implementation(libs.findLibrary("koin-core").get())` instead. + +### Pattern 3: Applying another plugin by ID from inside a precompiled plugin + +**What:** Inside a precompiled `.gradle.kts` you can write a normal `plugins { id("...") }` block, but only for plugin IDs whose markers are on the buildscript classpath via `build-logic/build.gradle.kts` (Pattern 1). Use bare string IDs — catalog accessors (`libs.plugins.X`) are NOT available in precompiled plugins, same constraint as Pattern 2. + +**Example — `recipe.kotlin.multiplatform.gradle.kts` (excerpt):** + +```kotlin +plugins { + id("org.jetbrains.kotlin.multiplatform") +} + +import org.gradle.api.artifacts.VersionCatalogsExtension +import org.gradle.kotlin.dsl.getByType +import org.jetbrains.kotlin.gradle.ExperimentalWasmDsl +import org.jetbrains.kotlin.gradle.dsl.JvmTarget + +val libs = extensions.getByType().named("libs") + +kotlin { + jvmToolchain(21) + + androidTarget { + compilerOptions { + jvmTarget.set(JvmTarget.JVM_11) // Android bytecode only (D-08) + } + } + + listOf(iosArm64(), iosSimulatorArm64()).forEach { iosTarget -> + iosTarget.binaries.framework { + baseName = "ComposeApp" // D-20;

Phase 1 does not require this; `shared/` builds android-less through KMP's androidTarget only when a consumer (composeApp) applies the android-application plugin. (Note: the current template's `shared/build.gradle.kts` DOES apply `com.android.library` directly. Verify whether this is still needed after the refactor; if the shared Android target compiles via KMP + androidTarget alone, we can drop the android-library plugin. See §Open Questions.) + +### Pattern 7: `recipe.jvm.server` — Ktor + Flyway, no Compose/Android + +```kotlin +plugins { + id("org.jetbrains.kotlin.jvm") + id("io.ktor.plugin") + id("org.flywaydb.flyway") + application +} + +import org.gradle.api.artifacts.VersionCatalogsExtension +import org.gradle.kotlin.dsl.getByType + +val libs = extensions.getByType().named("libs") + +kotlin { + jvmToolchain(21) + compilerOptions { + allWarningsAsErrors.set(true) + } +} + +dependencies { + "implementation"(libs.findLibrary("ktor-serverCore").get()) + "implementation"(libs.findLibrary("ktor-serverNetty").get()) + "implementation"(libs.findLibrary("ktor-serverContentNegotiation").get()) + "implementation"(libs.findLibrary("ktor-serializationKotlinxJson").get()) + "implementation"(libs.findLibrary("logback").get()) + "implementation"(libs.findLibrary("flyway-core").get()) + "implementation"(libs.findLibrary("flyway-database-postgresql").get()) + "implementation"(libs.findLibrary("postgresql").get()) + "testImplementation"(libs.findLibrary("ktor-serverTestHost").get()) + "testImplementation"(libs.findLibrary("kotlin-testJunit").get()) +} + +// Flyway plugin config — dev ergonomics only; runtime uses Flyway Java API in Application.kt +flyway { + url = System.getenv("DATABASE_URL") ?: "jdbc:postgresql://localhost:5432/recipe" + user = System.getenv("DATABASE_USER") ?: "recipe" + password = System.getenv("DATABASE_PASSWORD") ?: "recipe" + locations = arrayOf("classpath:db/migration") + cleanDisabled = true // safety: no accidental `flywayClean` in dev + baselineOnMigrate = true // tolerate an existing DB with no Flyway history + validateOnMigrate = true +} +``` + +**Note on `dependencies { "implementation"(...) }`:** inside precompiled plugins the named configurations aren't statically typed, so you must quote them. (In module `build.gradle.kts` files, `implementation(...)` is a typed method from the plugin's extension.) + +**Quoted configurations are a common footgun** — plan-checkers should verify these compile before Phase 1 sign-off. + +### Anti-Patterns to Avoid + +- **Putting Compose plugin ID inside `recipe.kotlin.multiplatform`:** breaks `shared/` (no Compose). Instead, layer `recipe.compose.multiplatform` on top (Pattern 4). +- **Applying `recipe.android.application` to `shared/`:** `shared/` is a library, not an app. The current template applies `com.android.library` directly in `shared/build.gradle.kts` — we may or may not need to keep that after refactor (see Open Questions). +- **Calling `startKoin` inside a `@Composable`:** composition-timed side effects race with UI rendering and panic on recomposition. Call at app entry, before composition starts (Android: `Application.onCreate()`; iOS: `iOSApp.init()`; Desktop: top of `main()` before `application { }`). +- **Adding Ktor Client, Compose, or SQLDelight deps to `shared/commonMain`:** violates D-19 / INFRA-06. Only `kotlinx-serialization` + `kotlinx-datetime` are allowed non-stdlib deps in `shared/`. (Phase 1 adds neither yet — `shared/commonMain` is truly empty beyond the placeholder package.) +- **Configuring `allWarningsAsErrors` via `kotlinOptions {}`:** deprecated in Kotlin 2.2+ (removed in 2.3). Use `compilerOptions { allWarningsAsErrors.set(true) }` at the `kotlin { }` extension level. [CITED: kotlinlang.org/docs/gradle-compiler-options.html] +- **Using deprecated `js()` target:** D-01 explicitly drops it; current `composeApp` and `shared` still reference it and must be removed. (Current files confirm `js { browser() }` blocks exist.) +- **Referencing `iosX64()`:** D-02 skips it; the current template doesn't reference it (verified in `composeApp/build.gradle.kts` and `shared/build.gradle.kts`), so this is a "don't add" guideline. +- **Calling `startKoin` twice on iOS:** if `iOSApp.init()` calls `doInitKoin()` AND `MainViewController` also calls `startKoin`, the second throws `KoinApplicationAlreadyStartedException`. Pick one call site (recommendation: `iOSApp.init()` — see §Koin Bootstrap). +- **Using the Flyway Gradle plugin for runtime migration at server boot:** the plugin is for ops ergonomics (CLI); runtime migration uses `Flyway.configure().dataSource(...).load().migrate()` in `Database.kt`. Mixing the two leads to "why didn't my migration run on boot?" debugging. +- **Using `transaction {}` in a coroutine / suspend context:** PITFALLS.md #5. Phase 1 doesn't touch DB yet, but the `recipe.jvm.server` plugin must not preclude using `newSuspendedTransaction` later — verify by NOT adding `exposed-dao` deps in Phase 1 (we don't; Exposed isn't added at all until Phase 3). + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Multi-module Gradle conventions | Scripted copy-paste of `kotlin { }` blocks | `build-logic/` + precompiled `.gradle.kts` plugins | One file per module, DSL identical to build.gradle.kts, full IDE support | +| Version management | Hardcoded versions in each module | `gradle/libs.versions.toml` + catalog accessors | Single source of truth (INFRA-01 hard rule) | +| Kotlin formatter/linter harness | Script `ktlint` as a `Exec` task | Spotless plugin | Handles multi-file, editor-config, caching, `spotlessApply` fix command | +| DB migration runner | Hand-rolled version table + SQL runner | Flyway (core + postgres dialect + plugin) | Industry standard; auto-apply on boot; repair command for corruption | +| KMP DI container | Service-locator singletons | Koin | Explicit graph, `koinViewModel()` integration with Jetpack Nav CMP, no codegen | +| KMP logger | `println` + `NSLog` via `expect/actual` | Kermit | Platform-correct defaults; `withTag`; format control; same API everywhere | +| Plugin classpath for build-logic | Manually adding kgp/agp as `buildscript` classpath | `compileOnly(libs.plugins.X.asDependency())` in build-logic/build.gradle.kts | Plugin markers resolve the real JARs; version stays in catalog | +| Postgres local dev | "install Postgres via brew" instructions | `docker-compose up -d` | Works identically on macOS/Linux; clean teardown; version-pinned | +| iOS K/N GC tuning | Custom finalizer plumbing in Koin modules | Set `objcDisposeOnMain=false`, `gc=cms` in `gradle.properties` | Addresses PITFALL #1 once, for all iOS code in the repo | + +**Key insight:** every item above is "the plumbing everyone eventually rebuilds badly; starting with the library means you get the edge-case handling for free." + +## Runtime State Inventory + +Phase 1 scaffolds infrastructure; it does not rename or migrate.

No external systems are affected. + +## Common Pitfalls + +### Pitfall 1: precompiled plugin can't see `libs.xxx` accessor + +**What goes wrong:** You write `implementation(libs.koin.core)` inside a `build-logic/src/main/kotlin/recipe.foo.gradle.kts` file — compile error: "Unresolved reference: libs". +**Why it happens:** Type-safe catalog accessors are generated only for module build scripts, not for precompiled plugins. `[CITED: Gradle docs — Using a catalog in buildSrc]` +**How to avoid:** Use the explicit lookup pattern (`extensions.getByType().named("libs").findLibrary("koin-core").get()`). +**Warning signs:** First red squiggle when you start writing a convention plugin. + +### Pitfall 2: double-applying KMP plugin + +**What goes wrong:** `recipe.compose.multiplatform.gradle.kts` applies both `id("org.jetbrains.kotlin.multiplatform")` and `id("recipe.kotlin.multiplatform")` — Gradle error "Plugin X already applied". +**Why it happens:** Forgetting that `recipe.kotlin.multiplatform` already applies KMP. +**How to avoid:** Compose plugin applies only `id("recipe.kotlin.multiplatform")` (which internally applies KMP) plus the Compose-specific plugins. See Pattern 4. +**Warning signs:** Clear error message; easy to fix once seen. + +### Pitfall 3: forgot `allWarningsAsErrors` on a specific compilation + +**What goes wrong:** Setting `compilerOptions { allWarningsAsErrors = true }` at the `kotlin { }` extension level covers common, but a per-target override (e.g. `androidTarget { compilerOptions { ... } }`) can silently mask it. +**Why it happens:** Kotlin 2.x DSL inherits options top-down but any child `compilerOptions { }` block creates its own scope. +**How to avoid:** Set `allWarningsAsErrors.set(true)` at the `kotlin { compilerOptions { } }` extension level only; don't re-open per-target `compilerOptions { }` blocks unless setting target-specific things (like `jvmTarget`). The `recipe.quality` plugin also has a `tasks.withType>().configureEach { ... }` safety net. +**Warning signs:** Build passes despite a deprecation warning in some sourceSet. + +### Pitfall 4: Koin `startKoin` called twice on iOS + +**What goes wrong:** `iOSApp.swift` calls `KoinKt.doInitKoin()`, THEN `MainViewController()` calls `startKoin { modules(appModule) }` again → `KoinApplicationAlreadyStartedException` on second app launch (or on cold iOS re-entry). +**Why it happens:** Both Android and iOS samples in Koin docs show different entry points; it's easy to copy both. +**How to avoid:** Pick a single `initKoin()` helper in `commonMain`, called from ONE place per platform. Canonical pattern: + +```kotlin +// composeApp/src/commonMain/kotlin/dev/ulfrx/recipe/di/Koin.kt +fun initKoin(config: KoinAppDeclaration? = null) = startKoin { + config?.invoke(this) + modules(appModule) +} +``` + +Then Android calls `initKoin { androidContext(applicationContext) }` from `Application.onCreate()` or `MainActivity.onCreate()`; iOS calls `initKoin()` from `KoinKt.doInitKoin()` in `iosMain`, invoked once in `iOSApp.init()`. `MainViewController()` does NOT start Koin — it assumes Koin is already started. `[CITED: insert-koin.io KMP setup docs]` +**Warning signs:** App crashes on second launch on iOS; works fine the first time after a clean install. + +### Pitfall 5: Ktor HOCON env-var syntax confusion + +**What goes wrong:** `port = ${?PORT}` behaves differently from `port = ${PORT:8080}`. The first makes the whole assignment disappear if `PORT` is unset (not what you want for defaults); the second fails at parse time if `PORT` is unset. +**Why it happens:** HOCON substitution semantics are non-obvious. `[VERIFIED: Ktor docs — heroku.md, sevalla.md, dokku.md]` +**How to avoid:** Use the two-line pattern for a default that can be overridden by env: + +```hocon +ktor { + deployment { + port = 8080 + port = ${?PORT} # if PORT is set, overrides; otherwise this line is a no-op + } +} + +database { + url = "jdbc:postgresql://localhost:5432/recipe" + url = ${?DATABASE_URL} + user = "recipe" + user = ${?DATABASE_USER} + password = "recipe" + password = ${?DATABASE_PASSWORD} +} +``` + +Read via `application.environment.config.propertyOrNull("database.url")?.getString()` in `Database.kt`. +**Warning signs:** Server crashes on startup with "Could not resolve substitution to a value" (fix: use `${?X}` form); or env override silently ignored (fix: the second line overrides the first only if env is set). + +### Pitfall 6: Flyway connects to Postgres at plugin-task time, not server-boot time + +**What goes wrong:** You run `./gradlew build` without Postgres running, and the build fails with a JDBC error — even though you didn't invoke `flywayMigrate`. +**Why it happens:** Some Flyway plugin versions evaluate the `flyway { ... }` block eagerly at configuration time. +**How to avoid:** Keep the Flyway plugin config simple and don't depend Flyway tasks on `classes`/`build`. Use the plugin *only* for CLI tasks (`./gradlew flywayInfo`, `./gradlew flywayMigrate`). The runtime migration path is through `Flyway.configure().dataSource(...).load().migrate()` in `Database.kt`. D-17's docker-compose documents starting Postgres before running the server; CI in Phase 11 will bring its own Postgres. +**Warning signs:** `./gradlew build` fails with JDBC connection refused despite not targeting Flyway. + +### Pitfall 7: Kotlin 2.x `compilerOptions` vs `kotlinOptions` + +**What goes wrong:** Copy-pasting `kotlinOptions { jvmTarget = "21" }` from an older tutorial — deprecation warning under Kotlin 2.x, fails the build under D-11 (`allWarningsAsErrors`). +**Why it happens:** Legacy DSL still "works" but is deprecated. +**How to avoid:** Always write `compilerOptions { jvmTarget.set(JvmTarget.JVM_21) }` (note `.set()` — it's a Provider property). `[CITED: kotlinlang.org/docs/gradle-compiler-options.html]` +**Warning signs:** Deprecation message: "The 'kotlinOptions' DSL is deprecated." + +### Pitfall 8: Wasm + Koin init order + +**What goes wrong:** `wasmJsMain` doesn't have an `iOSApp`-style init hook; `ComposeViewport { App() }` runs composition immediately. If Koin isn't started before `App()` composes, `koinViewModel()` throws. +**Why it happens:** The template's `webMain/main.kt` enters composition directly. +**How to avoid:** Call `initKoin()` at the top of the Wasm `main()`: + +```kotlin +fun main() { + initKoin() + ComposeViewport { App() } +} +``` + +Phase 1 doesn't ship any ViewModels yet, so this is a future-proofing note — but since D-01 keeps `wasmJs` and `composeApp/src/webMain/main.kt` exists, we should add it now to avoid "it broke silently in Phase 5" discoveries. +**Warning signs:** First Koin usage in wasmJs throws `NoDefinitionFoundException` despite `appModule` being correct. + +### Pitfall 9: `includeBuild` order in `settings.gradle.kts` + +**What goes wrong:** `includeBuild("build-logic")` is placed inside `dependencyResolutionManagement { }` instead of `pluginManagement { }`; the main project can't find `recipe.*` plugin IDs. +**Why it happens:** `includeBuild` inside `pluginManagement` makes the included build's plugins available to the root project's `plugins { }` blocks. Inside `dependencyResolutionManagement` it affects dependency resolution instead. +**How to avoid:** Place `includeBuild("build-logic")` inside `pluginManagement { }` at the top of `settings.gradle.kts`: + +```kotlin +pluginManagement { + includeBuild("build-logic") + repositories { + google() + mavenCentral() + gradlePluginPortal() + } +} +``` + +**Warning signs:** "Plugin [id: 'recipe.kotlin.multiplatform'] was not found" — almost always this. + +### Pitfall 10: iOS framework basename mismatch + +**What goes wrong:** `baseName = "ComposeApp"` in `composeApp` (D-20) but `baseName = "shared"` (template default) in `shared/`. Xcode imports both as `import ComposeApp` and `import shared` — works but inconsistent; if shared later gains its own framework publication, name casing will trip developers. +**Why it happens:** The template defaults to lowercase "shared". +**How to avoid:** Since `shared/` in this project is NOT published as its own iOS framework (it's a dependency of `composeApp`'s framework, compiled in), its `baseName` is irrelevant — but set it to `"Shared"` anyway for consistency, per D-07.

KMP's `androidTarget { }` declares the Android target but doesn't strictly require the android-library plugin for every module — sometimes it does. + - What's unclear: Whether dropping `com.android.library` from `shared/` breaks the composeApp Android consumer. + - RESOLVED: **Keep `com.android.library` applied in `shared/build.gradle.kts` directly in Phase 1.** Build a `recipe.android.library` convention plugin in a future phase if the direct application becomes a pattern. Don't block Phase 1 on this refactor. + +2. **Does `./gradlew build` invoke `flywayMigrate`? Should it?** + - What we know: Flyway plugin exposes `flywayMigrate`, `flywayInfo`, etc. as tasks; it does NOT hook them into `build` by default. + - What's unclear: Nothing — this is a choice. + - RESOLVED: **Do NOT wire Flyway tasks into `build` in Phase 1.** Migration is a server-boot concern; the plugin is for CLI ops (developer runs `./gradlew flywayInfo` manually to inspect state). CI integration lands in Phase 11. + +3. **Should we add `ktor-server-config-yaml` for a `application.yaml` alternative to HOCON?** + - What we know: Ktor 3.x supports YAML config via the `ktor-server-config-yaml` artifact; HOCON remains the default. + - What's unclear: Team preference. + - RESOLVED: **Stick with HOCON.** Our server dev is Kotlin/Ktor background (user profile) and HOCON is the historically canonical Ktor config. YAML is a nice-to-have, not worth the added dep. + +4. **How to verify iOS binary flags take effect without shipping a build to hardware?** + - What we know: Simulator launch eliminates most of the visible symptoms of PITFALL #1; Instruments on a real device would be the gold standard. + - What's unclear: Whether simulator-level verification is sufficient for Phase 1 sign-off. + - RESOLVED: **Verify at two levels:** (a) grep `gradle.properties` for the two flags (trivial but catches omission); (b) build the iOS framework and capture the Kotlin/Native link log for a line showing the GC + objcDisposeOnMain options. Real-device verification under Instruments is deferred to Phase 10 (UI chrome) when there's meaningful UI work to stress-test. + +5. **Does `recipe.quality` need a `targetExclude` for generated Compose Resources code?** + - What we know: Compose Multiplatform generates `Res.kt` under `build/generated/compose/resourceGenerator/...`. + - What's unclear: Whether Spotless/ktlint visit `build/` by default (they shouldn't, but worth confirming). + - RESOLVED: **Add `targetExclude("**/build/**", "**/generated/**")` explicitly in the Spotless config** (already in Pattern 5 example) to future-proof against any `.kt` file landing in those paths. + +## Environment Availability + +| Dependency | Required By | Available | Version | Fallback | +|------------|------------|-----------|---------|----------| +| Java / JDK | All Gradle builds | ✓ | OpenJDK 25.0.2 | — (JDK 21 toolchain resolved via Foojay if project JDK differs) | +| Docker | D-17 docker-compose / Postgres local | ✓ | 27.3.1 | — | +| Docker Compose | D-17 | ✓ | v2.40.0-desktop.1 | `docker compose` (v2 as subcommand) works identically | +| Xcode + iOS SDK | iOS framework build, simulator verification | ❓ (not probed — user on macOS; assume present given iOS-primary target) | — | If missing, developer installs from App Store before Phase 1 Wave 2 (iOS tasks) | +| Gradle daemon | All builds | Implicit (bundled with wrapper) | 8.x (from wrapper) | — | +| npx (for ctx7 docs lookups) | Research only, not build | ✓ (npm present) | — | — | +| Node / npm | Not required at build time | — | — | Project is pure Kotlin; no Node | +| Homebrew | Not required | — | — | — | + +**Missing dependencies with no fallback:** None detected.
