Genesis G1: CreateInstrument, and the from-empty spine reaches a note

Score::empty plus operations alone now materializes a note-bearing Score. The
chain CreateInstrument -> CreateStaff -> CreateRegion -> CreateStaffInstance ->
CreateVoice -> InsertEvent needed exactly one new link: CreateStaff already
demanded a live Instrument and nothing could create one.

Instrument is a root with no outbound references, so the operation carries no
referential preconditions -- only mint and byte-identical re-carry, on the
CreateStaff template. It designs no wire layout: Instrument joins
canonical_value! and the payload is one push_lp_bytes over the existing Codec,
so strict canonical-form rejection is inherited rather than written. Kind 31 and
tag 31 agree; schema_major is unconditionally 2 (Instrument's major-2 appends
are mandatory, not Option-hidden); bundle.rs is untouched and the op-block
accept-set stays 2, since that raise belongs to G2.

Two cross-cutting items the ruling required. Reduction now writes identity for
the first time, deriving next_counter from the log rather than trusting the
seed -- and the implementation is broader than contracted, covering minted
entity ids as well as operation ids, which is right: both burn counters. And the
from-empty path is pinned to reduce_operation_set_onto, since the base-free mode
skips referential preconditions by design; a test documents that asymmetry as
designed rather than as a bug to fix.

The contract's parallel-safety claim was WRONG and this commit corrects it.
Extending OperationKind is not containable to core+ops: Rust exhaustiveness
forces an arm in editor-core's barriers.rs, and because testkit depends on
editor-core, that one missing arm blocked conformance and requirement_labels
too. Three more downstream sites had 31 or a kind-count baked in as a literal --
layout-ir's barrier decode test, testkit's grammar vocabulary count, and the
textproj corpus generator. The subagent found the first two, reverted its
out-of-bounds edit, and reported rather than working around; the user authorized
the boundary crossing. Each literal now carries a comment saying it must move
with every tag append.

The text projection needed a companion bump, which the contract never
anticipated. Adding create-instrument to the kind production while holding
0.7.0 would leave two incompatible grammars claiming one version -- precisely
what the single-version gate exists to prevent -- so COMPANION_VERSION is now
0.8.0, the first kind appended since the header was gated. Cached projections do
not migrate and are not expected to: a TextProjection chunk is a non-canonical
accelerator, so a stale one is regenerated. The negative "wrong version" vector
had to flip, since 0.8.0 was the version it used as its future-and-therefore-
rejected example; it now names 0.7.0, which tests the deferred migrate-on-read
posture better anyway. Test headers that were literals now assert against the
constant.

Gate, all observed: fmt clean; clippy --workspace --all-targets 0 warnings;
1359 passed / 0 failed; requirement_labels 6/6; conformance 8/8 and 9/9 with
golden-gate, 96 decode vectors and 13 textproj vectors, every verdict agreed.
max_supported_major(OperationEnvelopeBlock) verified still 2. Both PDFs rebuilt.
Mutations i1, i3 and i5 re-run independently rather than taken on report: the
spine collapses to TargetMissing without the instrument, an unseeded
instrument_values misreports a base re-carry as RecreateContentMismatch, and a
seed-returning cursor yields 0 where 12 is required.

+`spec/RULING_GENESIS_PERSISTENCE.md`) adds `CreateInstrument` to
+`epiphany-ops`, the first rung of the genesis ladder
+(`spec/PLAN_GENESIS_OPS.md` §4). Its payload embeds the full `Instrument`
+value, so this crate's one required change is a single `canonical_value!`
+line (`Instrument` already has a `Codec` via `struct_codec!`, `codec.rs:1756`,
+which — same macro — already generates `impl TextValue for Instrument` too,
+so the Text Projection touch point the tranche needed cost nothing here).
+
+No new byte layout: `Instrument`'s canonical bytes are exactly what the
+whole-score codec already emits for it, made reachable per-value on the same
+seam every other `canonical_value!` entry uses. `value_types_round_trip_over_generator_corpus`
+does not exercise `Instrument` directly (the generator corpus does not walk
+`Score::instruments`), but the operation-layer decode-vector corpus
+(`epiphany-ops::vectors`) now pins a `CreateInstrument` envelope's literal
+bytes, which round-trips the same `Instrument` encoding through the op
+payload's `push_lp_bytes` wrapper — see that crate's own DECISIONS.md entry.

+## Genesis tranche G1 — `CreateInstrument`, kind 31 / tag 31 (2026-07-24)
+
+`spec/CONTRACT_GENESIS_G1_INSTRUMENT.md` lands the first rung of the genesis
+ladder (`spec/PLAN_GENESIS_OPS.md` §4): `CreateInstrument` mints an
+`Instrument` on the score root, set-union discipline identical to
+`create_staff` (`reduce.rs`), minus the graph-aware reference-resolution
+block — `Instrument` holds no outbound entity reference, so there is nothing
+for one to check. All fifteen touch points landed as specified: `codec.rs`'s
+`canonical_value!` (one line — `Instrument` already had a `Codec` and,
+because `struct_codec!` generates both, already had `TextValue` too, so the
+Text Projection touch point cost nothing extra); `payload.rs`'s
+`CreateInstrumentOp` + the five mechanical sites (`OperationKind` variant,
+`schema_major`, `discriminant`, `tag`, encode dispatch, tag-vocabulary
+entry); `envdecode.rs`'s decode arm and `sample_kind` sample;
+`v0.rs`/`migrate.rs`'s identity round-trip (born past v0, no lossy
+projection); `reduce.rs`'s dispatch + `create_instrument` +
+`instrument_values` (pin 8, six sites: both struct decls, init, the base
+seed, and the snapshot/restore pair); `textproj_kind.rs`'s production/parse;
+`fuzz.rs`'s generator arm 28 (`rng.below(28)` → `below(29)`); `vectors.rs`'s
+decode vector; `operation_catalog.tex`'s new section.
+
+**The identity cursor (pin 9) is gated on a *pristine-base* check the naive
+version got backwards.** The first attempt compared `self.graph` against
+`Score::empty(...)` at the *end* of `run()`, after every spine operation had
+already populated it — always false, so the cursor never advanced (the i5
+test caught this immediately: `next_counter` stayed `0`, not the expected
+`12`). The fix captures `from_empty_base` in `new_onto`, from the *pristine*
+`base` argument, before `graph` is cloned and mutated. This is also the
+mechanism that keeps the fix scoped to from-empty reduction only:
+`reduce_operation_set_onto` is the same entry point `epiphany-editor-core`
+calls on every edit (`EditorSession::materialize`), against a populated
+base, so an unconditional cursor-write there would have been a silent
+behavioral change to a crate this packet may not touch. Gating on
+`from_empty_base` makes onto-reduction against a populated base
+byte-for-byte unchanged — verified, not assumed, since editor-core is one of
+the crates the boundary below made un-editable, so its own test suite is the
+only check available and it does not run in this tree (see below).
+
+**The cursor's derivation walks two sources, not one.** `next_counter` is a
+*single* counter shared by every identifier kind
+(`IdentityContext::take_counter`), so scoping the fix to `InstrumentId`
+alone would have been wrong the moment a spine mixes kinds — which i1's own
+chain does (`CreateStaff`'s `StaffId`, `CreateVoice`'s `VoiceId`, ...).
+`derive_identity_cursor` takes the max over (a) every `OperationId` the
+`op_set` has ever accepted, via `OperationSet::slots()` — keyed by
+`OperationId`, so its key set is exactly "every id in the log" regardless of
+slot state (Single, Equivocated, held/pending) — and (b) every entity id in
+the final `self.objects`, decoded generically from `TypedObjectId`'s
+canonical form (2-byte discriminant + 16-byte `(replica, counter)`, for
+every variant but `Registered`) rather than a new per-kind accessor. This
+reads `TypedObjectId::canonical_bytes()` — already public — instead of
+adding a `replica()`/`counter()` method to `epiphany-core::ids`, which
+would have been a new public surface outside this packet's blast radius.
+Not fully general (a losing equivocation candidate's *entity* ids, as
+opposed to its `OperationId`, are invisible to this — no test in the
+required nine reaches that case, and closing it would need the same kind of
+new core-side accessor this design avoids); flagged rather than silently
+assumed complete.
+
+## Boundary conflict: `OperationKind` is exhaustively matched outside this
+## packet's blast radius (2026-07-24)
+
+The contract's blast radius lists only `epiphany-core/src/codec.rs` and
+eight `epiphany-ops/src/*.rs` files, and its "Parallel safety" note claims
+"this packet touches none of" `epiphany-editor-core`, `epiphany-editor-gui`,
+`epiphany-layout-ir`, `epiphany-render-svg`, `epiphany-glyphs`. That claim
+does not survive contact with the compiler: `OperationKind` gains a variant,
+and Rust's exhaustiveness check finds every downstream consumer.
+
+**`crates/epiphany-editor-core/src/barriers.rs:316`**, `subjects_of`, an
+exhaustive `match kind: &OperationKind` deriving edit-barrier subjects —
+fails to *compile* without a new arm (`CreateStaff`'s arm, one line, is the
+exact analogue: an instrument is a score-root object with no regional
+containment, same as a staff). Because `epiphany-testkit`,
+`epiphany-engrave`, `epiphany-render-svg`, and `epiphany-editor-gui` all
+depend on `epiphany-editor-core` (non-optionally), this one missing arm
+blocks the *entire* rest of the workspace from compiling — including
+`epiphany-testkit`, which owns `requirement_labels`, the decode-vector
+corpus regeneration/verification, and the conformance suite. `cargo test
+--workspace` and `cargo clippy --workspace --all-targets` both fail at this
+single error and never reach a single test.
+
+**`crates/epiphany-layout-ir/src/barrier.rs:1112`**,
+`decode_rejects_unknown_discriminants`, hardcodes `31u8` as "one past the
+[`OperationKindTag`] vocabulary" — a *runtime* test failure (the crate
+compiles fine), now stale because 31 is `CreateInstrument`. This is not a
+new failure mode: the test's own comment records it happened once already
+("This assertion named 30 until Push 5 / P4 — by which time 30 was
+`TransposeInterval`, so the test was pinning a bug"). The fix each time is
+mechanical: bump the literal to the new one-past-the-vocabulary value (`32`)
+and its expected `tag: 31` to `tag: 32`.
+
+Both files are on this packet's explicit do-not-touch list (a parallel agent
+owns them in a separate worktree), so neither was edited — an initial,
+incorrect edit to `barriers.rs` (made before re-deriving the boundary against
+the actual compiler output) was caught and reverted before landing; `git
+status` on both crates is clean in the delivered tree. Consequently:
+`cargo test --workspace`, `cargo clippy --workspace --all-targets`, the
+conformance suite, and `requirement_labels` could not be executed against
+the full workspace in the delivered state — only against the seven crates
+that do not depend on `epiphany-editor-core`
+(`epiphany-determinism`/`epiphany-core`/`epiphany-bundle`/`epiphany-ops`/
+`epiphany-textproj`/`epiphany-layout-ir`/`epiphany-glyphs`), all of which
+are green (`epiphany-layout-ir` excepted, for the one stale-vocabulary test
+above). This is reported to the coordinator rather than worked around; see
+the packet's final report for the exact reproduction commands and error
+text.

+Ratified with the genesis operation tranche's first rung (G1;
+\texttt{spec/CONTRACT\_GENESIS\_G1\_INSTRUMENT.md}, executing
+\texttt{spec/RULING\_GENESIS\_PERSISTENCE.md}). \texttt{CreateStaff}
+(Section~\ref{sec:k0:create-staff}) already requires a live
+\texttt{Instrument}, and until this primitive existed nothing could mint one
+except a canonical base --- so a document created empty
+(\texttt{Score::empty}) and given only operations could reach a
+\texttt{CreateStaff} but never satisfy it. \texttt{CreateInstrument} is the
+single missing link between an empty score and a note: with it, the chain
+\texttt{CreateInstrument} $\rightarrow$ \texttt{CreateStaff} $\rightarrow$
+\texttt{CreateRegion} $\rightarrow$ \texttt{CreateStaffInstance}
+$\rightarrow$ \texttt{CreateVoice} $\rightarrow$ \texttt{InsertEvent}
+materializes a note-bearing score from operations alone.
+
+\textbf{Payload schema.} \texttt{CreateInstrumentOp \{ instrument: Instrument
+\}} --- the full abstract-instrument value (schema major 2): identity, name,
+declared pitch range, abbreviation, sound configuration, transposition
+interval, default clef, default staff-line configuration, and unpitched
+members. Unlike every carried type in
+Section~\ref{sec:k0:structural-containers} and
+Section~\ref{sec:k0:create-staff}, \texttt{Instrument} holds no outbound
+entity reference, so this primitive needs no referential precondition at
+all --- only mint and idempotence.
+
+\textbf{Canonical encoding.} The length-framed canonical bytes of
+\texttt{instrument}. \texttt{Instrument}'s schema-major-2 appends
+(\texttt{sound\_config}, \texttt{default\_clef},
+\texttt{default\_staff\_lines}, and the rest) are mandatory fields, not
+\texttt{Option}-hidden, so no lower-major layout for this payload exists:
+under minimal stamping (Binary Format companion \sectionsc{Schema Major 2})
+a block carrying a \texttt{CreateInstrument} is \emph{born at v2}, exactly
+as \texttt{CreateStaff} is --- not the value-dependent shape
+\texttt{CreateRegion}/\texttt{SetStaffLayout} use.
+
+\textbf{Reduction rule.} Set-union creation of an \texttt{Instrument} on the
+score root, mirroring \texttt{CreateStaff}'s discipline exactly since
+neither carried type references another entity: a create mints the
+instrument live if its id is fresh; a repeat create carrying a
+byte-identical value reduces idempotently
+(\texttt{NoOpReason::AlreadyApplied}); a create whose id is already live
+with a \emph{differing} value is a precondition no-op with
+\texttt{RecreateContentMismatch}; and a create naming a tombstoned id is a
+precondition no-op with \texttt{TargetTombstoned}. There is no
+graph-aware reference-resolution block, because there is nothing for one to
+check.
+
+\textbf{Conflict cases.} None at reduction time (set-union; the
+differing-value re-create is a precondition gate, not a conflict).
+
+\textbf{Undo semantics.} Undo of a create tombstones the minted instrument;
+\texttt{StrictInverse} conflicts if a live staff references it (tombstoning
+it would strand the staff).
+
+\textbf{Re-anchoring.} Not applicable, for the same reason as
+\texttt{CreateStaff}: an instrument mint references no tombstonable anchor.
+There is no \texttt{DeleteInstrument} in this catalogue revision ---
+\texttt{CreateStaff} ships today with no \texttt{DeleteStaff} either, and
+full delete/modify coverage of the genesis-authored fields is later
+tranche work (\texttt{spec/PLAN\_GENESIS\_OPS.md} G3).
