Voice call history (Python-LXST-bounded rebuild)

Android voice call history rebuilt to stay strictly within unmodified Python LXST 0.5.1 facts and lifecycle behavior.

Feasibility boundary

• LXST-kt is pinned to immutable v0.0.8; no LXST change was needed (parity proven against Python LXST).
• Persisted outcomes reduced to: CONNECTED_ENDED, MISSED_INCOMING, DECLINED_LOCAL, REJECTED_REMOTE, BUSY_REMOTE, CANCELLED_LOCAL, NOT_CONNECTED, FAILED, INTERRUPTED.
• No authoritative UNANSWERED, DROPPED, or media/transport terminal causes.
• Outgoing ringing unavailable; connectedAt = established-callback observation time.
• Single serialized service owner; durable admission before exposure; identity-scoped blocking (delivery + telephony); migration/transfer at format v8.

Scope

• Reduced domain model (9 outcomes, 7 Columba-observed failure reasons)
• Room storage v5/v6 with reduced CHECK constraints, deletion authority, recovery
• Serialized service lifecycle owner + symmetric native/Python callback adapters
• Incoming durable admission via existing pre-ringing policy seams
• Migration/transfer, deletion, non-resurrection, identity scoping
• Voice history UI + Call details with honest ambiguity (no unsupported claims)
• Obsolete-code absence; reduced exact-candidate matrix

Verification

• Unit suites: data 378, rns-api 247, rns-host 565/565, app 6038 - all green.
• ktlint, detekt, Android lint, minified releases (both flavors) pass.
• Migration/import round trips for every reduced outcome pass.

Not merged. Review against the reduced feasibility boundary.

Greptile Summary

The PR adds identity-scoped Android voice-call history while limiting persisted outcomes to evidence available from the pinned LXST implementations.

• Adds Room schemas, migrations, repositories, deletion authorities, and recovery for durable call records.
• Introduces serialized host-process lifecycle recording for native and Python call backends.
• Extends migration format v8 to transfer call records and non-resurrection tombstones transactionally.
• Adds history and detail UI, navigation, identity-aware blocking, and cross-module tests.

Confidence Score: 5/5

The PR appears safe to merge because no concrete blocking or independently actionable non-blocking defect remains after reviewing the persistence, lifecycle, migration, IPC, and presentation paths.

Durable admission, terminal updates, deletion authority, migration rollback, restart reconciliation, and IPC mappings preserve their stated contracts across the changed native and Python call paths.

Important Files Changed

Filename	Overview
rns-host/src/main/kotlin/network/columba/app/rns/host/call/ServiceCallLifecycle.kt	Adds serialized durable admission, transition recording, terminal finalization, and restart reconciliation without an accepted defect.
rns-api/src/main/java/network/columba/app/rns/api/call/AcceptedCallLifecycle.kt	Coordinates accepted-call observations, retries, cleanup, and process-local ownership across both backends.
app/src/main/java/network/columba/app/migration/CallHistoryMigrationImporter.kt	Validates the reduced evidence model and imports tombstones before records within the encompassing Room transaction.
app/src/main/java/network/columba/app/migration/MigrationImporter.kt	Integrates format-v8 call history into the existing transactional database import.
data/src/main/java/network/columba/app/data/db/ColumbaDatabase.kt	Advances the Room schema with explicit migrations for call history and deletion authority.
data/src/main/java/network/columba/app/data/db/dao/CallHistoryDao.kt	Implements idempotent lifecycle transitions, terminal writes, deletion checks, and open-attempt recovery.
data/src/main/java/network/columba/app/data/db/dao/CallHistoryDeletionDao.kt	Atomically records deletion authority and removes finalized calls to prevent later resurrection.
rns-ipc/src/main/kotlin/network/columba/app/rns/ipc/client/ClientRnsCore.kt	Keeps the changed Binder-facing core contract aligned with its AIDL and server adapters.
app/src/main/java/network/columba/app/ui/screens/VoiceHistoryContent.kt	Adds the identity-scoped voice-history presentation and interaction surface.
app/src/main/java/network/columba/app/viewmodel/ChatsViewModel.kt	Exposes call-history state and actions to the Chats presentation layer.
