All four findings verified independently against the tree before fixing; all
four hold, and the first is worse than filed.
P1 (normative wire docs) is not a G2a omission but a G1 regression. 3b09595
touched operation_catalog.tex and text_projection.tex and no other .tex, so it
shipped four falsehoods: binary_format's payload-layout and tag tables stop at
kind 30 while 31 is assigned in code, and req:binfmt:kind-discriminants says
each row pins the payload's byte layout; binary_format:2432 still asserts there
is no CreateInstrument; core_spec:12186 still says Canvas.layout_defaults and
Instrument.range reach only the non-canonical snapshot; and the catalog gained
a CreateInstrument section with no version bump against its own convention.
G2a now repairs all four and adds its own two surfaces, with explicit version
and changelog dispositions for binary_format (0.11.0 -> 0.12.0), the catalog
(0.9.0 -> 0.10.0, covering G1 retroactively), and two narrow core_spec edits.
The core_spec:5114 amendment is pinned rather than left to a subagent. The
K8 paragraph has a load-bearing half the ruling does not touch -- root and
canvas remain structural givens no operation mints -- and only the
outside-the-operation-set clause is superseded.
P1 (source) adds ops/src/lib.rs re-exports and the textproj parse.rs literal
HEADER fixture, whose tracking test is a tripwire that fires by design.
P2: s8 and s9 gain the mutations they lacked, and s2's was fabricated --
set_metadata contains no comparison to reverse, it records and overwrites
unconditionally, so the mutation is now setter-local first-write-wins. s7's
framing was backwards: WorkingSnapshot is transaction rollback, so omitting a
chain retains a failed transaction's write rather than losing history, and the
wrong framing would have sent the test hunting the wrong symptom.
Records the G2b holdout: ScoreTuningContext's Codec deliberately drops
accidental_extensions while OperationSet::accept stores envelopes as objects,
so a naive full-value SetTuningContext diverges between a live session and the
same document reloaded -- and canonical_value! cannot see it, because its
check compares bytes and never the originating value.
