Ledger dropped its lean/ submodule in ledger/ledger#3336. Its flake input, whose URL names the revision, is now this repository's only pin there, and a development build opts in through LEDGER_LEAN_DIR. README.md and AGENTS.md still described two pins.

AGENTS.md also stated the downstream rule backwards. Main follows Ledger's pin, not the other way round: a change is cut onto the pinned revision, lands together with its C++ half, and main fast-forwards to it when Ledger's pull request merges. Squashing or rebasing a pinned commit would change the revision Ledger names.

This is a docs-only change; the oracle tree is unchanged. Merge it by fast-forwarding main to a41644b, not by squash or rebase, so the next pin-moving change can be cut on top of it.

and main fast-forwards to it when Ledger's pull request merges.
