Push-only category controls; all default true. Required inbox history/read state remain independent. Optional source opt-ins are configured separately under subscriptions.

Independent optional source opt-ins, all false by default. Enable before the original event; re-enabling starts a fresh episode and does not backfill delayed or historical events. Opt-out cancels the optional reason and its queued push, preserving authorized history and independent reasons. selected_posts applies to separately typed native and imported trader selections.

Implemented source contract scope, not a deployment or activation attestation. Financial proof admits only a single direct finalized Solana mainnet USDC transfer in legacy or static-account version-0 transaction format between existing token accounts. Loaded-address version-0 transactions, associated-account creation/closure, CPI, additional token transfers, compound action steps, deposit failures, bridges and cross-chain outcomes remain unavailable. Successful fixtures are synthetic; compatibility with actual Privy output is unproven, and its transfer API gives no Solana message-version guarantee. Imported publication alerts use owner-proved original identity, current author/removal/visibility and prospective follow/subscription episodes. Current owner proofs use bounded batches under one deadline; capacity or dependency failure returns 503 without partial counts. Large imported-history admission remains open. Version-0 proof requires explicitly empty address lookup descriptors and loaded address arrays; all accounts must be static.
