Ledger Entry Canonical

EXACT canonical bytes of this entry's record under a published hash recipe.

Additive (2026-09-17, Toshikatsu / HORIZON SHIELD gap): GET /ledger/{entry} returns a fresh JSONResponse projection; the published content_hash_spec / legacy_record_sha256_spec both require the reader to re-serialize record themselves. This path serves the exact bytes the named recipe hashes, so:

sha256(response.content).hexdigest() == X-Expected-Sha256

with zero re-serialization on the reader side. Does not change /ledger/{entry} behavior.

Default recipe: content_hash_spec when chain.content_hash is present, else legacy_ascii_escaped_v0 when record_sha256 is present. Override with ?recipe=.
