+# Android signing policies
+
+Public verification policies for ConnectBot's Hermit signing service. Files are
+named by the immutable source repository ID, not a caller-supplied name. They
+contain public certificates and allowed identities only. Private keys and their
+filesystem locations stay in the appliance's private configuration.
+
+Trusted workflows in `connectbot/actions` read this repository (immutable ID
+1215286979) at protected `main`. They resolve a commit before fetching a policy
+file and record the policy commit and digest in final provenance. Source builds
+cannot replace this policy through workflow inputs or source checkout contents.
+
+The builder and finalizer run from protected `android-signer-v1` in
+`connectbot/actions` (immutable ID 1369420724). Caller workflow paths identify
+eligible CI entry points; empty digest lists intentionally mean identity-based
+authorization. Exact executed workflow commits remain recorded in certificates,
+receipts and provenance. Ordinary source/caller edits and reviewed builder branch
+updates do not require changes here or on the VM.
+
+Key identity, package, allowed source ref, signing algorithm/rotation policy,
+Sigstore trust, or appliance revision changes require coordinated review and
+provisioning. Export policies with the appliance's offline admin tool after key,
+certificate and lineage validation; do not hand-edit fingerprints or policy hashes.
+The test repository policy uses disposable keys. Its workflow cannot publish to
+Google Play; production Play access is scoped to repository ID 123235 and alpha.
