P13-S27: record execution review 8 (CLEAN) and the invariant's terminating case 

Execution review 8 returned zero findings against 480a299 -- the first clean
round since execution, and the second in the document's history.

This is a RECORD, not an amendment. It changes no pin, gate, test, mutation,
touch row or staged file. It appends a history row, marks the last
ratification-time bullet satisfied, and adds two things a clean round is the
only way to reach:

1. The invariant's terminating case. The locator amendment 7 fixed assumed
   every review produces an amendment -- review N produced amendment N. A
   clean review produces none, so a reader following the rule would look for
   an "amendment 8" that does not exist. Now: if the last execution review
   row shows 0 findings, no amendment followed and no pass is outstanding;
   the chain has closed. Same class as the Total-row locator defect, and
   reachable only once a round came back clean.

2. The history preamble's "every amendment is a row ... the amendment count
   IS the number of rows" was already false when written. The converse does
   not hold: round 19 returned zero findings and produced no amendment, so
   the identity broke the moment that row was added. Rows are events;
   0-finding rows produced no amendment. Corrected in the preamble and in
   the Total row's note.

What the clean round establishes and does not: it is round 11's criterion --
convergence evidenced, not findings exhausted -- and it is the stronger of
the document's two clean rounds, because what it reviewed had been executed,
gated and measured rather than only argued. It is not proof of correctness.
It reviewed amendment 7; no round has ever re-derived the whole document.

Established as of this record: the implementation is unchanged since
amendment 1's comment correction; gates 1-3 re-run cold against that exact
tree under amendment 4 (1577 passed / 0 failed / 0 ignored, 42 suites; clippy
and fmt clean on pinned 1.95.0); gates 4, 4a and §2 rules A/B re-run under
amendments 2 and 4; M7 ran with its three observations and control, examined
by three independent reviews with nothing returned against it; and every
finding across all eight reviews was in this contract, not in the 21 staged
files.

What remains is the owner's acceptance decision. This document does not make
it. Round 1's ratification was claimed by the author after a single round and
withdrawn; that precedent is why this record stops at the evidence.

Implementation still staged, still not accepted.

what it reviewed had been executed, gated and measured rather than only argued.

not re-derive the whole document, and **no round ever has**. The defect record is the

- **Gates 4, 4a and §2's rules A and B** were re-run under amendments 2 and 4.
- **M7 ran**, returning its three observations and its control, and **three independent
reviews examined it and returned nothing against it.**
- **Every finding since execution has been in this contract, not in the 21 staged
files** — across all eight reviews.
