``` make check-source-bolt CHECK_BOLT_PREFIX="--prefix=BOLT-route-blinding" BOLTVERSION=guilt/offers ``` Other than textual changes, this does: 1. Ensures we put total_amount_msat in onion final hop (reported by @t-bast). 2. Require that they put total_amount_msat in onion final hop. 3. Return `invalid_onion_blinding` exactly as defined by the spec (i.e. less aggressive when we're the final hop) (also reported by @t-bast, but I already knew). See: #5823 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Changelog-EXPERIMENTAL: `offers` breaking blinded payments change (total_amount_sat required, Eclair compat)
