humility 0.13.0.699 failed to write cosmo-os QSPI on alfred

I was trying to write a new host phase1 to flash on cosmo-os from alfred, and three attempts in a row failed with
variants of this.

alfred(cosmo-os)% h qspi -D /staff/andy/os/cosmo.rom && cycle

alfred(cosmo-os)%

I then grabbed the humility binary from igor which just reports as 0.13.0 and that succeeded first time:

alfred(cosmo-os)% pfexec ./humility qspi -D /staff/andy/os/cosmo.rom
humility: attached to 1fc9:0143:WTECYVHYHSQD4 via CMSIS-DAP V1
humility: Using existing slot settings
humility: skipping sector 0
humility: erased 3.19 MiB in 3 seconds
humility: hashed 32.00 MiB, wrote 3.19 MiB in 6 minutes

Start with the qspi command path and its CMSIS-DAP/probe-rs transfer handling, using the provided h qspi -D ... reproduction on cosmo-os. Compare humility 0.13.0.699 with the successful 0.13.0 binary as a baseline. Done means the current version can write the image repeatedly without transfer or USB timeout errors.
