Execution was dispatched, began, and stopped at pin 3 before its first edit:
pin 3 required item 10 to keep an opening sentence scoped to "cross-cutting
structures" -- a defined term denoting pin 1 group A -- while gaining a nested
list spanning every group. Reported, not patched, per the frozen-pin
discipline; this is that amendment, after five review rounds.
Item 10 gains a subordinated universal deferring to explicit permission only:
"Except where the re-anchoring rules of Chapter~\ref{ch:semops} explicitly
permit transient dangling states during edits, every graph reference resolves
to an extant object." The ratified sentence is retained verbatim beneath it
with its own exception and cross-reference, so nothing normative is removed.
Three subordination forms were tried and the reasoning behind the first two was
itself defective twice. A cross-cutting-scoped exception is not shown wrong --
only unproved, since deciding it needs the exception's surface derived. A bare
"as the re-anchoring rules permit" is ambiguous: it can be read as deferring to
coverage, and coverage is not permission. The re-anchoring table does reach
group E (Cue source, Trajectory endpoint pitch), but both rows prescribe
cascade deletion or immediate replacement -- neither leaves anything dangling,
so reach establishes governance, not permission. The surface derivation is
presented for disposition, not filed: no ledger row is added, and filing in
this contract means a row.
Pin 6 gains the new anchor, an exactly-once requirement within
req:graph:score-graph-invariants, and M21 to sign it. M19 is rebuilt: it
truncates the real opening AND places one complete anchor after the nested
list, so uniqueness stays at one and does not mask the mutation, a prefix slice
passes, and the pinned complete-literal slice starts past the list and fails --
the two anchor kinds driven to opposite verdicts by one mutation.
Two edits belong to this ratification act rather than to pin 11, because the
contract was already dispatched and its top status already untrue; deferring
them would have left the document lying about its lifecycle for the whole of
execution. Both are applied here: this section's status literal, and a
clause-level replacement in the top status paragraph, pinned as Markdown source
so that the ratification date, the owner's authority and the no-count rule all
survive. Pin 11 keeps only the landed forms.
Baseline unchanged at 1583 passing across 42 suites. No pin 3 or pin 6
implementation target has been modified; execution resumes at pin 3.
