Stop storing active live locations with the channel

[gpunto]

Goal

Since #6742, a channel's active live locations were stored with the channel and read back on the cache-first load. Stopping a live location does not update the stored list, so after a restart a stopped location came back from the cache and stayed until its original end time, because the server response only adds locations.

Part of AND-1576

Implementation

• Stop storing active live locations with the channel. They come from the server response and events only.
• Remove the stored field and its list converter, and bump the database version.
• Drop active live locations from the in-memory channel cache too, so loading a channel again in the same session can't bring back a stopped one.
• Ignore live locations when deciding whether a cached channel changed, so channels with an active location are not written again on every insert.

Active live locations are still exposed as before: ChannelState, the channel list and GlobalState read them from the in-memory global state, which the server responses and events keep up to date. Only the local copy goes away, so other members' locations show once the first server response arrives, not from the cache.

Testing

• Updated ChannelMapperTest and LocationConverterTest, and DatabaseChannelRepositoryCacheTest checks cached channels come back without live locations and that an unchanged channel with live locations is not written again.
• On a device, another member shared a live location, the current user loaded the channel, then the sharer stopped and the app restarted. Before the change the stopped location was back in the global state after the restart. With it, it stays gone. Upgrading from the previous database version opens cleanly. Querying the channel again in the same session after the stop no longer brings the location back either.

Walkthrough

The channel database entity and mappings no longer persist active live locations. The Room database version is now 206, and list-based location JSON conversion and related tests were removed.

ChannelEntity and its mappers no longer store or map active live locations. LocationConverter no longer converts location lists, and the Room database version changes to 206. Fixtures and tests no longer cover persisted live locations or list conversion.

Merge Risk: 🟡 Moderate · up to c16d4

Upgrading the app wipes the local chat database. Messages that were written offline or are still waiting to send can be lost permanently. Add a migration that only drops the obsolete column, or explicitly accept this behavior before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to c16d4

Removing saved active-location lists prevents stopped locations from being restored through that cache after restart. However, the database upgrade can also erase unsent messages and pending changes from the account’s local data. Preservation and rollback guarantees are not established.

Retained concerns

• High · reliability · inferred: The 205-to-206 upgrade invokes destructive database recreation rather than limiting removal to active-location storage. It can discard unrelated pending messages, updates and deletions, breaking offline recovery and losing local intent that server refresh cannot reproduce. The fallback policy is pre-existing, but this PR introduces the transition that activates it.

Security review details

Security Blast Radius

• inferred — The destructive transition affects the entire local database opened for a user, rather than one channel or location field. The builder names databases using userId, and the registered entities include messages, reactions, attachments, drafts and synchronization state. This is a local upgrade outcome, not an established remotely triggerable attack.

Trust Boundaries and Controls

• observed — The inspected change removes a durable source of active-location state. The existing in-memory query consumer remains in place, and the database factory retains its user-scoped naming and internal visibility. The storage transition does not introduce a new public database operation.

Resilience and Maintainability Implications

• inferred — Queued deletion and update retries also depend on persisted local messages. Destructive recreation can erase that intent before it reaches the server, so ordinary server refresh is not equivalent to preserving pending user-requested changes. This connects the upgrade concern to continuity of removal intent as well as offline reliability.

Hardening Proposals

• proposed — Use a targeted schema migration that removes obsolete channel location storage while preserving pending messages, attachments, drafts and synchronization state. Define preservation and recovery behavior for interrupted upgrade and downgrade rather than relying on successful database opening as evidence of safe migration.

- Line 93: Add a Room migration from version 205 to 206 in the ChatDatabase
migration setup, and ensure it drops only the obsolete
ChannelEntity.activeLiveLocations column while preserving existing tables and
unsynced messages. Register the migration so opening a version 205 database uses
it instead of fallbackToDestructiveMigration().
