| """V3 trusted change-list — grade off NET EFFECT + provenance from the parsed OOXML. |
| |
| `build_trusted_changes(base_view, deliv_view, author)` returns a structured, grader-derived |
| description of what the model did this turn, computed from the two docx (baseline turn-input |
| + deliverable) — never from model free-text: |
| |
| * model_edits — the model's OWN this-turn tracked changes, each with a |
| net-effect ``is_noop`` flag (a del+reinsert that nets to |
| unchanged is flagged however it is split / nested / whitespaced). |
| * counterparty_dispositions — for every counterparty revision in the baseline, its fate: |
| accepted | rejected | pending | countered (derived by diffing |
| baseline vs deliverable — an explicit accept/reject the grader |
| can see, so "leaving it untouched" (pending) is NOT acceptance). |
| * model_comments — the model's this-turn comments (a SEPARATE list — a comment is |
| never a tracked change). |
| * net_texts — original_base / accept_all / reject_all for net-effect reasoning. |
| |
| Because everything is derived from OOXML, the list is not forgeable, and net effect is |
| invariant to how an edit is split/nested/whitespaced (the jv1c "split reinsert" evasion |
| cannot survive). This is the V3 evidence the judge grades against (see judge_prompts). |

| Count-aware (a multiset). A still-PENDING revision (matched by that key) is EXCLUDED: it is |

| and stripping it was the finding-A/B hole (it masked a phantom ``w:del`` / bare run whose text |
| was copied from a pending revision). |
| |
| cl2: both the multiset key AND the stripped text are the wrapper's FULL reject text |
| (``_para_reject_text`` of the wrapper), not its counter-reduced own ``.text``. Accepting a |
| counterparty ``w:ins`` that WRAPPED a nested model strike (the real ins-23/ins-29 shape on s24-t4) |
| promotes the strike's text into reject-all; the pre-cl2 own-``.text`` key both mis-detected the |

| and under-stripped (leaving the promoted fragment as a residue) → the spurious −1.0 gate failure. |
| Keying on the full reject text is w:id-free (detection stays text/count-anchored — robust to |

| |
| gx1 (nested replacements, duplicated ids): a resolved INSERTION wrapper also contributes its |
| accept-all text. Some expert tools write a replacement as ``<w:ins><w:del>old</w:del>new</w:ins>`` |
| instead of Word's sibling del + ins; the skill tells the model to accept both ids of a replacement, |
| after which the deliverable holds only ``new`` as plain text while the reject-all text of the |
| wrapper is ``old + new`` — the strip missed, ``new`` survived as residue and honest accepts on |
| inputs of that shape were floored. Both wrappers are iterated as raw elements (``_revision_ |
| elements``) rather than through the parsed view, so an element sharing a ``w:id`` with an |
