name: CI — Mobile iOS

# Reusable CI counterpart to cd-mobile-ios.yaml. Verifies a React Native iOS
# app before merge: dependency install, typecheck, optional lint, optional unit
# tests, and a compile that is neither signed nor uploaded.
#
# Emits the single `ci / ci` status context required by the org branch-
# protection rulesets. As in ci-python-app.yaml, `ci` is an aggregator job
# gated on `needs`, so a caller job keyed `ci` reports `ci / ci` and that one
# context is red whenever any job below it failed.
#
# Input names mirror cd-mobile-ios.yaml wherever the same concept exists:
# node-version, ruby-version, working-directory, cache-dependency-path,
# fastlane-lane.
#
# Runner split. The JS checks run on ubuntu-latest; only the native compile
# runs on macOS, because only that step needs Xcode and CocoaPods. The macOS
# runner is billed at a multiple of the Linux rate, so putting `npm ci` +
# typecheck + tests on Linux keeps the expensive runner to the one job that
# genuinely requires it. `macos-26` matches cd-mobile-ios.yaml's runner, so CI
# compiles on the same Xcode image the deploy builds on.
#
# The compile is a `xcodebuild build`, not `archive` + `export`: it passes
# CODE_SIGNING_ALLOWED=NO / CODE_SIGNING_REQUIRED=NO / CODE_SIGN_IDENTITY="",
# and there is no App Store Connect or fastlane match step anywhere in this
# file. It therefore needs no signing certificates and no secrets, which is why
# `workflow_call` here declares none.
#
# run-lint and run-tests default to FALSE. The only current caller of
# cd-mobile-ios (proposal-system, working-directory `mobile`) declares exactly
# five npm scripts — start, ios, android, typecheck, postinstall — so a lint or
# test script cannot be assumed to exist. Turn them on per repo once the
# scripts are there.
