        Backfill a pipeline for a specific wallet address. Discovers the
        wallet's historical activity from our own appearance index (all-address
        log appearances plus native/internal transfers) and queues the matching
        historical beats on every backfill-ready network the pipeline subscribes
        to — EVM wallets (0x…) fan out over the pipeline's EVM networks, Solana
        wallets over Solana. Per-network availability is gated server-side:
        networks join the fan-out as their historical index goes live. The
        response lists exactly which networks were queued.

                    Restrict the fan-out to these networks (subset of the
                    pipeline's backfill-ready chains)
                  example:
                    - base
                fromBlock:
                  type: integer
                  description: >-
                    Lower block bound, applied as-given to every selected chain
                    — pair with a single-chain `chains` filter since block
                    numbers differ per chain. Takes precedence over time bounds.
                toBlock:
                  type: integer
                  description: Upper block bound (same caveat as fromBlock).
                fromTime:
                  type: string
                  description: >-
                    Lower time bound (ISO-8601 or epoch-ms), converted to a
                    block bound per chain from its observed block time.
                    Approximate by design — 'the last month', not a block-exact
                    cut.
                  example: '2026-06-23T00:00:00Z'
                toTime:
                  type: string
                  description: Upper time bound (same conversion as fromTime).
