Cut 4. Rulings 14 and 15 moved the state off the repo: an instance owns its
mind and a service owns that state. Every layer that existed only to make a
repo-resident, git-committed, multi-clone store safe is now dead weight.
`epiphany-core/src/pipeline_store.rs` goes whole, 1,251 lines: the commit
profile, the epoch/foreign-type opener, the committed-blob checks, the
main-work-tree resolution, the read handle, the writer lease and its branch
binding, the holder record, and the 20 tests that pinned those rules. With it
go `PipelineWriterHolder` and its wrapper, `validate_pipeline_writes`, the two
`lib.rs` lines, the `.gitattributes` binary marker and the `.gitignore` lock
line. No Epiphany code can now open a pipeline store, take a lease, or read
git for pipeline purposes.
`pipeline_documents.rs` gains a local `PipelineRefusal` in place of the import.
D2 splits the landed thirteen variants: the six repo-store refusals
(`NotRepoRoot`, `NoMainWorkTree`, `StoreNotMarkedBinary`, `LockNotIgnored`,
`WrongBranch`, `WriterLeaseHeld`) die here, and so do `MissingIdentity` and
`Unavailable`, which lost their last raiser with the opener and the lease.
`ForeignEpoch` and `ForeignStore` stay because `decode` and
`validate_pipeline_write_envelope` still raise them; D2 hands them to the organ
when admission moves.
The seven document tests the cut map names, plus the schema derivation test,
move into `pipeline_documents.rs` rather than waiting for Cut 6, so no rule
sits unpinned in between. They lose the git scaffolding that has nothing left
to set up, and the key test now validates one envelope directly instead of
going through the deleted batch validator. Sample payloads that named the
deleted file were rewritten so the negative greps are honest.
This cut removes an owner and installs no replacement; the organ becomes the
owner in Cut 8.
Builds clean with no warnings: `cargo check -p epiphany-core --lib --tests`
and `cargo check -p epiphany-release-bundle --bin epiphany-state`.
`cargo test -p epiphany-core --lib` passes 168/168, down from 180: 20 tests
died with the file and 8 came back with the documents.

Cut 3a (D2): git never merges the bytes of .epiphany/pipeline/pipeline.cc,
so every divergent merge goes through the merge command. Without `binary`, a
NUL-free MessagePack store is classified as text on a core.autocrlf=true
machine (probe P8). The per-operation cultcache-rs sibling lock is ignored.
The published pipeline schemas are pinned to LF so the byte-for-byte
derivation test holds on a CRLF checkout.
Builds: no code change.
