Subject: [PATCH] Add TestFlight workflow: upload to internal testing on every
 merge to main
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

macOS runner, xcodegen generate, cloud-managed signing via an App Store
Connect API key (no certificates in secrets), build number pinned to
the run number so uploads never collide, and -exportArchive with
destination=upload pushes straight to App Store Connect — internal
testers get the build automatically once processing finishes. Requires
ASC_KEY_ID / ASC_ISSUER_ID / ASC_KEY_P8 repository secrets (documented
in the workflow header); serialized via a concurrency group.

+# key mints/updates certificates and profiles on the fly — no certificates or provisioning
+# profiles are stored in the repo or in secrets. Three repository secrets are required:
+#
+#   ASC_KEY_ID     App Store Connect API key ID            (App Store Connect → Users and
+#   ASC_ISSUER_ID  App Store Connect API issuer ID          Access → Integrations → App Store
+#   ASC_KEY_P8     the .p8 private key, base64-encoded      Connect API → create a key with
+#                                                           "App Manager" role)
+#   base64 encode:  base64 -i AuthKey_XXXXXXXXXX.p8 | pbcopy
+#
+# The build number is the workflow run number (monotonic per repo), so TestFlight never
+# rejects a duplicate CFBundleVersion. Uploads become available to INTERNAL testers
+# automatically once App Store Connect finishes processing — no extra distribution step.
