SetCanvasLayoutDefaults and SetSpellingPrecedence, kinds and tags 32/33, on the
SetMetadata LWW pattern: advisory last-writer-wins, no conflict, no idempotence
short-circuit, seeded from the base so a value-restoring undo of the first
operational write reaches the pre-operational value. Both carried types already
had Codec impls, so the packet designs no wire layout -- canonical_value!
delegation and one push_lp_bytes each, inheriting strict canonical-form
rejection rather than writing it.
Both stamp schema major 0 unconditionally, staying in the catch-all arm. The
op-block accept-set is untouched at 2; epiphany-bundle has an empty diff. The
raise to 3 belongs to G2b, and the chunk schema minor -- a MUST no writer has
ever honoured -- belongs to G-minor, filed as P13-S14 and deliberately not
fixed here.
Most of this commit is documentation the vocabulary had outgrown. G1 shipped
five normative falsehoods because its contract declared the wire surfaces out
of scope, and Push 4a left TransposeInterval out of both of core_spec's
normative listings. So binary_format's payload-layout and tag tables now reach
33 rather than 30, its snapshot-only bullet records that it is empty and why,
two spelled-out payload counts move from eight to nine, and core_spec's
listings gain all four missing kinds. The Pass-12 K8 doctrine is narrowed
rather than reversed: the root and canvas remain structural givens no operation
mints, and only the claim that the score's contents arrive outside the
operation set is superseded.
Two generators were stale by two tranches and fed corpora other suites treat as
exhaustive. layout_stub's is now derived from PAYLOAD_FREE with an explicit
Registered append instead of a hand-written match, so future built-ins follow
structurally; s10 asserts PAYLOAD_FREE union {Registered} so deleting that
append cannot pass.
Companion 0.8.0 -> 0.9.0, binary format 0.11.0 -> 0.12.0, catalog 0.9.0 ->
0.10.0 (covering G1 retroactively). 102 decode vectors, regenerated.
Coordinator verification: 1371 passed / 0 failed, clippy 0 warnings, fmt clean,
conformance 8/8 and 9/9, requirement_labels 6/6, four PDFs at 0 undefined
references, goldens byte-identical, accept-set confirmed still 2. Mutations
s3/s5/s7/s10 re-run independently and each observed to kill its test.
Two findings beyond the contract. max_supported_major is not reachable outside
epiphany-bundle -- mod bundle is private and the symbol is absent from its
pub use -- so the gate's "assert it in code" was unsatisfiable without touching
a crate the contract forbids; verified by reading the unedited source instead.
And core_spec carries two P12-K8 references, not one; the contract named only
the first, so the second is annotated here for consistency.
