Three leftovers from the extraction, plus the documentation it needs to
survive.
`KeyPackageRotationManager` still built its leaf capabilities from bare hex
(`0x000A`, `0xF2EE`, `0x000A`) with the two meanings of `0x000A` -- last_resort
as an extension, self_remove as a proposal -- distinguishable only by which
list they were in. That set is now `MarmotCapabilities.mipKeyPackageLeaf()`,
beside the other two profiles, with the ordering marked load-bearing: those
bytes go into published KeyPackages and define KeyPackageBundleStore's v4
snapshot format.
`MarmotManager` and `MarmotConvergenceEngine` still spelled
`exporterSecret("marmot", "group-event", 32)` literally at three call sites, so
the binding's key derivation was stated in four places. They read it off
`MarmotGroupPolicy.commitExporter` now, which is where the engine reads it too.
`CurrentProfileWelcomeTest` and `CommitPreservesLeafIdentityTest` sat in the
`mls/` test tree with ten and three Marmot imports between them; they test
Marmot's current profile, so they move to `marmot/appComponents/`.
The README states the invariant as a command you can run, and scopes it
honestly: shipped code only. Two tests under `mls/components/` do decode real
Marmot components, because an interop test is worth more against payloads that
actually exist -- a fixture is data, an import in the engine is a dependency.
It also writes down the three things a second binding has to know, the one
that will bite (a policy is behaviour, not state, so a restore that forgets it
silently drops the rules), and why the default is permissive rather than
closed.
The plan's Stage 1 is marked landed with what it cost and what Stage 3 still
owes: MlsGroupManager names `nostrGroupId` 147 times, so cordn needs its own
manager over the same MlsGroup rather than reusing that one. §5.1's coupling
measurements are marked superseded rather than deleted -- they are what the
stage was scoped against.
Verified: :quartz:jvmTest 5082, :commons:jvmTest 2202, both green;
:quic, :cli, :marmotBench and :amethyst all compile.
