Expand test to cover Bolt11 custom TLVs

This commit only expands an existing automated test. It renames a test function, adds assertions, and uses new test helpers to verify that custom extra data fields (called 'custom TLVs') are preserved when paying a BOLT11 invoice. There is…

Introduce custom TLVs in `pay_for_bolt11_invoice`

This commit is a routine API enhancement for the Lightning Dev Kit's rust-lightning library. It adds the ability for users to include custom data (called 'custom TLVs') when paying a BOLT11 invoice through the simpler `pay_for_bolt11_invoi…

Custom TLVs are user-controlled data attached to payment onions; improper validation or serialization could theoretically affect parsing, but no such bug is introduced or fixed here.API refactor changes the public signature of `pay_for_bolt11_invoice`, which is a breaking API change but not a security flaw.No mention of vulnerability, CVE, security fix, or bug in commit title or message.

Centralize custom TLV validation behind `CustomTlvs`

This commit is a code cleanup, not a security fix. It moves the existing checks that validate custom Lightning payment data (custom TLVs) from one place in the code into a new dedicated wrapper type called RecipientCustomTlvs. The same rul…

Refactor only: validation logic moved, not changedReturn type of with_custom_tlvs changed from Result to Self because validation now happens earlier in RecipientCustomTlvs::newSame reserved-type rejections retained: keysend (5482373484) and async-payment invoice request (77_777)

Introduce Blinded Payment Dummy Path test

This commit adds a new automated test for a feature called 'dummy hops' in blinded payment paths. It only touches test code and does not change any production logic. There is no security issue here.

Introduce payment dummy hops in DefaultRouter

This commit changes how LDK builds private payment routes for BOLT12 offers. Instead of revealing the real number of hops to the payee, it now pads every blinded payment path with three fake 'dummy hops' by default. This is a privacy impro…

Introduce Payment Dummy Hop parsing mechanism

Cleanup: Remove redundant (hmac, nonce) from codebase

This commit removes an older, now-redundant HMAC/nonce authentication mechanism from LDK's blinded payment paths. The code had already introduced a newer 'ReceiveAuthKey' way to authenticate the same data, so the old (hmac, nonce) fields a…

rustfmt: Remove skip from request_refund_payment

This commit is purely a code-formatting cleanup. It removes a `#[rustfmt::skip]` directive from a Rust function and lets rustfmt reformat the code. There is no functional change, no bug fix, and no security relevance.

Refactor: Introduce `get_payment_info` closure for invoice creation
