+# CI Configuration for SDK Validation
+
+This folder contains the source-of-truth config for the `SDK Validation` workflow.
+
+Main files:
+
+- Workflow: `.github/workflows/sdk-validation.yml`
+- Config: `.github/ci/ci-run-config.json`
+- Config preparation: `scripts/ci/sdk_validation/prepare-config.js`
+- Shared shell logging: `scripts/ci/sdk_validation/lib/logging.sh`
+- Build/test helpers: `scripts/ci/sdk_validation/`
+
+The workflow supports both:
+
+- automatic runs on `pull_request`
+- manual runs via `workflow_dispatch`
+
+## Workflow Shape
+
+There is one workflow, `SDK Validation`, with four user-facing validation flows controlled by workflow inputs:
+
+- `build_sdk_targets`
+- `build_test_app`
+- `run_tests`
+- `lint_pods`
+
+Internally, the workflow also has one technical job, `Prepare CI config`, that:
+
+- validates workflow input defaults against `.github/ci/ci-run-config.json`
+- parses boolean and JSON overrides
+- validates matrix structure
+- derives the effective matrices used by downstream jobs
+
+Default validation profile from `.github/ci/ci-run-config.json`:
+
+- `build_sdk_targets = true`
+- `build_test_app = true`
+- `run_tests = true`
+- `lint_pods = false`
+
+Concurrency behavior:
+
+- runs are grouped by `workflow + ref`
+- starting a new `SDK Validation` run on the same branch cancels the previous in-progress run on that branch
+
+## Validation Flows
+
+### `build_sdk_targets`
+
+What it does:
+
+- runs `build_sdk_matrix` across `build_matrix`
+- for each matrix entry:
+  - resolves SwiftPM dependencies inside the configured scratch path
+  - discovers library products from `Package.swift`
+  - builds each SwiftPM library target
+- on the primary `sdk_tests.runner + sdk_tests.xcode` entry, also builds the iOS package scheme `Adapty-Package`
+- runs a separate `macos_sdk_build` job on `sdk_tests.runner + sdk_tests.xcode`
+
+Scripts involved:
+
+- `scripts/ci/sdk_validation/build-spm-library-targets.sh`
+- `scripts/ci/sdk_validation/list-library-targets.js`
+- `scripts/ci/sdk_validation/lib/logging.sh`
+
+Inputs that affect it:
+
+- `build_sdk_targets`
+- `build_matrix_override_json`
+
+Behavior:
+
+- default config is blocking
+- `build_matrix` entries may use `informational: true`; those entries run with `continue-on-error`
+- the primary `sdk_tests.runner + sdk_tests.xcode` entry must exist in `build_matrix`
+- the primary build entry must have `informational: false`
+
+Artifacts:
+
+- `swift-build-products-log-<runner>-xcode-<xcode>`
+- `swift-build-macos-log-xcode-<xcode>`
+
+### `build_test_app`
+
+What it does:
+
+- builds `Examples/AdaptyRecipes-SwiftUI/AdaptyRecipes-SwiftUI.xcodeproj`
+- writes CI-specific demo constants before the build
+- uploads `xcodebuild.log` even when `xcodebuild` returns non-zero
+
+Scripts involved:
+
+- `scripts/ci/sdk_validation/write-demo-constants.sh`
+- `scripts/ci/sdk_validation/build-demo-app.sh`
+- `scripts/ci/sdk_validation/lib/logging.sh`
+
+Inputs that affect it:
+
+- `build_test_app`
+- `build_matrix_override_json`
+
+Behavior:
+
+- runs only on the single primary entry derived from `build_matrix`
+- the helper writes `exit_code` to `GITHUB_OUTPUT`
+- the workflow uploads the log first, then fails in a separate step if `exit_code != 0`
+- effectively blocking, because the derived primary entry must have `informational: false`
+
+Artifact:
+
+- `demo-build-log-<runner>-xcode-<xcode>`
+
+### `run_tests`
+
+What it does:
+
+- runs `sdk_tests` across `sdk_tests_matrix`
+- for each matrix entry:
+  - resolves SwiftPM dependencies
+  - runs `swift test`
+- uploads `swift-test.log` even when `swift test` returns non-zero
+
+Scripts involved:
+
+- `scripts/ci/sdk_validation/run-sdk-tests.sh`
+- `scripts/ci/sdk_validation/lib/logging.sh`
+
+Inputs that affect it:
+
+- `run_tests`
+- `sdk_tests_matrix_override_json`
+
+Behavior:
+
+- default config is blocking, because the default matrix contains one primary entry with `informational: false`
+- override entries may use `informational: true`; those entries run with `continue-on-error`
+- `sdk_tests_matrix_override_json` does not have to include the primary `sdk_tests` entry
+- there is no whitelist mechanism
+- the helper writes `exit_code` to `GITHUB_OUTPUT`
+- the workflow uploads the log first, then fails in a separate step if `exit_code != 0`
+
+Artifact:
+
+- `sdk-tests-log-<runner>-xcode-<xcode>`
+
+### `lint_pods`
+
+What it does:
+
+- runs `pod lib lint` for:
+  - `Adapty.podspec`
+  - `AdaptyUI.podspec`
+  - `AdaptyPlugin.podspec`
+
+Scripts involved:
+
+- `scripts/ci/sdk_validation/run-pod-lib-lint.sh`
+- `scripts/ci/sdk_validation/lib/logging.sh`
+
+Inputs that affect it:
+
+- `lint_pods`
+
+Behavior:
+
+- blocking
+- runs only on `sdk_tests.runner + sdk_tests.xcode`
+- there is no whitelist mechanism
+
+Artifact:
+
+- `pod-lib-lint-log-xcode-<xcode>`
+
+## Logging Model
+
+All artifact-producing shell helpers use the same logging contract from `scripts/ci/sdk_validation/lib/logging.sh`.
+
+After log initialization:
+
+- stdout and stderr are mirrored to both live Actions output and the log file
+- early failures are written into the artifact log
+- helpers must not use extra `tee -a` logging on top of the shared logger
+
+Current artifact-owning helpers:
+
+- `build-spm-library-targets.sh`
+- `build-demo-app.sh`
+- `run-sdk-tests.sh`
+- `run-pod-lib-lint.sh`
+
+Special cases:
+
+- `build-demo-app.sh` and `run-sdk-tests.sh` intentionally do not fail their step on command non-zero
+- instead, they store `exit_code` in `GITHUB_OUTPUT`, so the workflow can upload the log artifact before failing
+
+## Trigger Modes
+
+### `pull_request`
+
+Automatic runs happen on:
+
+- `opened`
+- `reopened`
+- `synchronize`
+- `ready_for_review`
+
+For `pull_request`, the workflow does not use manual inputs. It derives the effective profile directly from `.github/ci/ci-run-config.json`.
+
+With the current config this means:
+
+- `build_sdk_targets = true`
+- `build_test_app = true`
+- `run_tests = true`
+- `lint_pods = false`
+
+### `workflow_dispatch`
+
+Manual runs use the workflow inputs shown in the GitHub UI. If an input is left empty, `Prepare CI config` falls back to `.github/ci/ci-run-config.json`.
+
+## Manual Run Inputs
+
+### Boolean flags
+
+- `build_sdk_targets`: enable SDK builds
+- `build_test_app`: enable demo app build
+- `run_tests`: enable `swift test`
+- `lint_pods`: enable CocoaPods lint
+
+At least one of these flags must be `true`.
+
+### JSON overrides
+
+- `build_matrix_override_json`: override for SDK build matrix and primary build entry selection
+- `sdk_tests_matrix_override_json`: override for `swift test` matrix
+
+Accepted formats:
+
+- JSON array of matrix entries
+- JSON object with `include: [...]`
+
+Matrix entry shape:
+
+```json
+{
+  "runner": "macos-15",
+  "xcode": "26.2",
+  "informational": false
+}
+```
+
+Rules:
+
+- `runner + xcode` pairs must be unique
+- `informational: true` means the matrix entry is advisory and uses `continue-on-error`
+- if `build_sdk_targets=true` or `build_test_app=true`, `build_matrix` must include the primary `sdk_tests` entry with `informational: false`
+- `sdk_tests_matrix_override_json` may omit the primary `sdk_tests` entry entirely for custom test-only runs
+
+## Validation Rules
+
+- `Prepare CI config` fails if all four boolean flags are `false`
+- workflow input defaults in `workflow_dispatch` must stay in sync with `.github/ci/ci-run-config.json`
+- matrix override JSON must be a non-empty array or an object with `include[]`
+- matrix entries must be unique by `runner + xcode`
+- `build_test_app` always derives a single-entry matrix from the primary build entry
+
+## Xcode Selection Behavior
+
+- matrix jobs use `setup-xcode` for the requested version
+- if a matrix entry is `informational: true` and Xcode is unavailable, that entry is skipped with a warning
+- if a matrix entry is `informational: false` and Xcode is unavailable, that entry fails
+- `SDK macOS build` and `CocoaPods lint` are single-Xcode jobs and fail if the configured Xcode is unavailable
+- iOS-specific steps (`Adapty-Package` and `AdaptyRecipes-SwiftUI`) run only on the primary `sdk_tests.runner + sdk_tests.xcode`
+
+## Manual Run Guide
+
+### GitHub UI
+
+1. Open `Actions`.

+  -f run_tests=false \
+  -f lint_pods=false \
+  -f build_matrix_override_json='[{"runner":"macos-15","xcode":"26.2","informational":false}]'
+```
+
+Run only demo app build:
+
+```bash
+gh workflow run "SDK Validation" --ref master \
+  -f build_sdk_targets=false \
+  -f build_test_app=true \
+  -f run_tests=false \
+  -f lint_pods=false
+```
+
+Run only tests:
+
+```bash
+gh workflow run "SDK Validation" --ref master \
+  -f build_sdk_targets=false \
+  -f build_test_app=false \
+  -f run_tests=true \
+  -f lint_pods=false
