Meta Vens b4f88d2980 Close Soul's Cut 3a findings and land rulings 10-12
One store per clone, numeric attempt and pass, and identity enforced by the
profile that owns the commit. The three files change together because the
profile's validator signature, the documents that implement it and the store
that installs it are one interlocking contract; no smaller split builds.

Ruling 10, one store per clone. `main_work_tree` resolves the clone's main
working tree from any worktree through the git common dir, and both
`PipelineStore::open` and `PipelineWriter::attach` go through it, so a caller
in a worktree reads and admits into the main tree's store. A bare clone or any
layout without one main tree refuses `NoMainWorkTree`; there is no
worktree-only mode. `require_branch` binds to the main tree, so a campaign
whose branch is checked out only in a linked worktree is refused rather than
quietly given a second store.

Ruling 11, numeric labels. `attempt` and `pass` are `u32`, keyed
`cut-<cut>.h<N>` and `cut-<cut>.s<N>`.

Ruling 12, identity on first write. `TypedCommitStore` now validates a whole
batch against the image it will be applied to (`validate_writes`), replacing
the per-envelope hook rather than adding a second one. The pipeline profile
refuses a first write that does not carry the identity, so the single owner can
never admit a store its own opener refuses (F1).

F2: a finding label carries no dot and parent locals parse strictly, so two
documents cannot compose one key. Soul's collision pairs are tested.
F3: parent ids are parsed with an exact segment count, a campaign match, a kind
match, a validated local, and a marker followed by digits.
F4: a resolution's subject id is validated as a full id of its declared kind,
by `PipelineRef` itself, so kind and id cannot disagree anywhere.
F5: the ten document wrappers, the identity, provenance and holder wrappers and
their value fields are crate-private, and the crate's only commit path to a
pipeline store is a `cfg(test)` helper taking `&PipelineWriter`. Binding the
owner to the lease is Cut 3b.
F6: covered by ruling 10, with the previous claim corrected: a worktree does
not keep its own store, and a second attach from any tree is refused.
F7: the holder record is written only under the lock and removed on drop, and a
refusal names a holder only when it is plausibly current, matching host and
live process incarnation. A record left by a crash names nobody.
F8: the git checks read the committed blob at HEAD, so they answer the same on
every machine. Attribute and exclude files are nulled on every git child. The
working tree and `.git/info/exclude` deliberately do not count, because the rule
is about what the repository commits.

Low items: `value_types!` is the single field list, emitting each struct and its
`Bounded` impl from the same tokens, and format rules moved into the field types
(`Label`, `Slug`, `OrgRepo`, `FullSha`, `Sha256Hex`), so a field cannot be
declared without being validated and a list without a cap does not compile. That
applies the `Org/Repo` check to every repo field. `LandedNameKind` is deleted and
`LandedName` is a name and a path. The schemas carry `maxLength` and `maxItems`.

Builds clean with no warnings; `cargo test -p epiphany-core --lib` passes
179/179.
