The short version

What changed, and why it matters

This commit only adds a new automated CI test job that checks whether Core Lightning can be downgraded to the previous release (v25.09). It does not change any production code, wallet logic, network handling, or cryptographic operations. There is no security-relevant change visible in the diff.

Recommended action

No security action required. This is a routine CI/infrastructure change. If reviewing for release readiness, verify that `tests/test_downgrade.py` itself covers downgrade safety (database schema compatibility, RPC behavior, etc.), but that file is not part of this commit.

Security signals we found

No strong security signals were identified.

downgrade: we need to remove "impressions" from askrene datastore when downgrading to v26.06.

This is a database downgrade helper fix, not a live network vulnerability. Core Lightning's downgrade tool previously failed to strip out new 'channel impression' records when rolling a database back to version v26.06. The patch teaches th…

downgrade tool: fix invalid memory bug

This commit fixes a typo in a database downgrade helper tool. The bug caused the tool to pass a negative number (turned into a huge positive size) when copying data, which led to an out-of-memory (OOM) error. The fix swaps two variable nam…
