Bug: OutOfMemoryError in Polycentric getSystemState / CRDT deserialization when liking a video

[Marshall-Wagner]

Reproduction steps

No single deterministic step — it crashes intermittently during normal use once the
Polycentric identity has grown large:

1. Use a Polycentric identity that has a lot of accumulated activity over time.
2. Browse and load videos normally (e.g. open videos from a playlist / subscriptions).
   No specific button press is required.
3. The app OOM-crashes — sometimes on a background okhttp network thread with no
   interaction (stack 2), and sometimes via the like/dislike pill's opinion() path
   (stack 1).

Common factor: the heap reaches its ~768 MB limit while Polycentric's full SystemState
is being deserialized (getSystemState → StorageTypeCRDTSetItem.fromProto).

Actual result

Actual result: the app crashes to Grayjay's in-app "App Error" screen with a
java.lang.OutOfMemoryError (heap already at its ~768 MB growth limit). Screenshot below;
full text stacks are in the logs section.

Expected result

Loading a video, reading/displaying its existing rating state, and
liking/rating should all work without crashing, no matter how large the Polycentric
identity has grown. Polycentric's SystemState handling should not load the entire dataset
into memory in a way that can exhaust the heap. If the stored state is too large to load
safely, the app should degrade gracefully (e.g. fall back to the existing v208 "disable
Polycentric on problems" path) instead of hard-crashing the whole app.

[neverson42]

I have Polycentric disabled in settings. Still getting a very similar crash during video playback. I thought it might be a storage space issue since my phone is nearly full of dog pictures, but i transferred 12gb off and deleted a bunch of stuff this morning and it's still occurring sporadically.

I dont think this issue is rooted in polycentric.

Full text of my most recent error is below in case it helps y'all.

Following for a solution / fix!

Hi, thank you for reporting this issue.

@Marshall-Wagner , @neverson42, @st3rox

To help us troubleshoot this issue, can you please share this information?

1. Which other plugins were enabled?
2. Roughly how many subscriptions did you have per plugin?
3. Was Subscription Exchange enabled or disabled?
4. Did the crash happen soon after opening the app or refreshing subscriptions?
