Show replies in context of their threads (#4871)
* Don't reconstruct threads from separate posts * Remove post-level dedupe for now * Change repost dedupe condition to look just at length * Delete unused isThread * Delete another isThread field It is now meaningless because there's nothing special about author threads. * Narrow down slice item shape so it does not need reply * Consolidate slice validation criteria in one place * Show replies in context * Make fallback marker work * Remove misleading and now-unused property It was called rootUri but it was actually the leaf URI. Regardless, it's not used anymore. * Add by-thread dedupe to non-author feeds * Add post-level dedupe * Always count from the start This is easier to think about. * Only tuner state need to be untouched on dry run * Account for threads in reply filtering * Remove repost deduping This is already being taken care of by item-level deduping. It's also now wrong and removing too much (since it wasn't filtering for reposts directly). * Calculate rootUri correctly * Apply Following settings to all lists * Don't dedupe intentional reposts by thread * Show reply parent when ambiguous * Explicitly remove orphaned replies from following/lists * Fix thread dedupe to work across pages * Mark grandparent-blocked as orphaned * Guard tuner state change by dryRun * Remove dead code * Don't dedupe feedgen threads * Revert "Apply Following settings to all lists" This reverts commit aff86be6d37b60cc5d0ac38f22c31a4808342cf4. Let's not do this yet and have a bit more discussion. This is a chunky change already. * Reason belongs to a slice, not item * Logically feedContext belongs to the slice * Update comment to reflect latest behavior
