tegwick 98c6cd24c3 CB-WP-0006 T05: K9's assertion, K11's format, and the AM-11 suites
K11 is implemented: crates/cb-events/src/store.rs, magic + version header,
4-byte little-endian length prefix, append-only. Reimplemented not
assimilated per ADR-0005 §2 — no new dependency, and AM-4a/AM-4b are
unchanged at 246,250 / 317,021 because nothing entered the graph.

The operative clause is "detected", so corruption is tested rather than
assumed: a tail short by one byte, a half-written length prefix, a length
prefix corrupted to claim more than the file holds, foreign magic, and a
future format version are each rejected with a distinct error. A reader
that accepts a truncated tail is worse than no format, because it silently
returns a short history that looks complete.

AM-11 is earned. LogStore has two impls — MemLogStore and FileLogStore —
driven through ONE conformance(). The trait carries raw/set_raw precisely
so the corruption controls live in the shared suite: a format contract
that only one impl enforces is not a contract. The same shape is
retro-fitted to KernelRng, which is what AM-11 actually names: ChaChaRng
and NullRng now pass one suite asserting bounds, draw(1) == 0, determinism
across fresh instances, and shuffle preserving the multiset. They were
previously exercised by two separate tests, which is why "met, narrow" was
never earned and ADR-0005 §4 downgraded it.

K9 gets the assertion it did not have: snapshot at seq N + events N+1..M
must equal the from-genesis fold, hash-compared, on GroundState,
single-seed on purpose — AM-7's probe folds a multi-seed log, which is not
a replay of anything, and that defect is not repeated. Two positive
controls: the log must exceed 50 events, and the mid-log snapshot must
differ from the end state or "apply the remainder" is vacuous.

Proof it works: the exact mutation that SURVIVED in CB-WP-0005 — making
Snapshot::take discard its EventSeq — now fails on the K9 assertion.

AM-11's mutation breaks NullRng::draw to return its bound and the shared
suite fails. That is what M-D4-SWAP claims — either impl substitutable —
and exactly what two separate per-impl tests could never demonstrate.

M-D1-MUT: 7 -> 8 of 14. CB-EV-0001's scoreboard is refreshed: AM-2, AM-5
and AM-9 added, AM-6 moved to enforced, and the headline total corrected
from 4 to 8 — it had gone stale inside the same workplan that produced it.
