descriptor: Add CanSelfExpand()
CanSelfExpand() reports whether a descriptor can be expanded without
needing any caches or private keys to be provided by the caller of
Expand().
✓ Descriptive subject✓ Provides detailed explanatory context
What changed, and why it matters
This commit adds a new helper method called CanSelfExpand() to Bitcoin Core's descriptor system. It lets the code ask whether a wallet descriptor can produce its Bitcoin address(es) on its own, without needing a saved cache or private keys. The change is mostly a new capability with matching tests; it does not by itself fix a known bug or change user-facing behavior, but it lays groundwork that could later be used to avoid loading private keys just to display addresses.
Recommended action
No immediate action required. Treat as a routine refactor/enabler commit. Review follow-up commits that actually call CanSelfExpand() in wallet loading or GUI paths to determine whether any security-relevant behavior changes.
Security signals we found
01
New API surface added to descriptor subsystem (CanSelfExpand)
02
No change to existing expansion, signing, or key-derivation logic
03
No bounds, memory, or cryptographic operations modified
04
Test-only addition of a hardened musig() descriptor case
05
Comment clarifies that aggregate MuSig pubkeys cannot be cached, so participants must self-expand
Evidence from the diff
The patch introduces a pure virtual bool CanSelfExpand() on the Descriptor interface and implements it across PubkeyProvider subclasses (Origin, Const, BIP32, MuSig) and DescriptorImpl. The rule is: constant public keys and non-hardened BIP32 derivations can self-expand; hardened BIP32 derivations, private-key-based providers, and MuSig aggregates with any non-self-expandable participant cannot. Tests are updated to assert that descriptors without hardened steps report CanSelfExpand()==true. A mock descriptor in wallet load tests is updated to implement the new method. There is no logic change to Expand() or wallet behavior in this commit.
