M1 frontier

In scope

Every record carries emitter, sequence number, previous-record hash, and signature; periodic signed checkpoints.
jostoph verify: walk the chain, exit non-zero on any gap, truncation, or bad signature — absence becomes detectable, not just forgery.

Out of scope

Archive walking (S4's verify --deep).

Boundary

The chain is per emitter. Cross-emitter ordering is not promised and no rule may depend on it.

Acceptance

Dropping, reordering, or truncating records in a test stream is caught by verify; an intact stream passes from genesis.
