offers: remove `blinding` from decode JSON-RPC.
What the developer wrote
Authored by Rusty Russell
offers: remove `blinding` from decode JSON-RPC.
Deprecated in 24.11, disabled in 25.05.
Changelog-Removed: JSON-RPC: `decode` field `blinding` (use `first_path_key` as per modern BOLT naming)
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
What changed, and why it matters
This commit removes an old JSON-RPC field named `blinding` from the `decode` command output. It was already renamed to `first_path_key` in a previous version and has now been fully removed after a deprecation period. This is a routine cleanup, not a security fix.
No security action needed. Users relying on the deprecated `blinding` field should migrate to `first_path_key`.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch deletes the deprecated blinding field from the decode RPC response in plugins/offers.c and updates the deprecation table. The replacement field first_path_key remains present and contains the same data. No logic, parsing, or cryptographic handling changed.
