# T611 repair handoff

Run: `20261029T190406Z`; table: `T611`; account: `zeta3`.

All three ranked findings in `agents/critiques/T611.md` still applied to the fresh authenticated API document and rendered page. They have been repaired in the same private draft. `agents/critiques/T611-repaired.md` records their dispositions in the original order. No table was created, offered, published or reviewed.

## Governing skill

Read and byte-checked the coordinated archived versions in [the repair manifest](../20261029T190406Z-repair-skills/manifest.json), at repository path `agents/runs/20261029T190406Z-repair-skills/manifest.json`:

- Local skill SHA-256: `28ecbeeccb0c5e5d6eb541b5a5b0f88aec47b154374d909085116d34f5629199`.
- Live skill SHA-256: `28ecbeeccb0c5e5d6eb541b5a5b0f88aec47b154374d909085116d34f5629199`.
- The canonical skill in the source snapshot has the same digest.

`repair-skill-evidence.json` preserves the manifest reference and both versions explicitly.

## Changes and checks

Removed the unsupported `Data properties.digits` property, linked the first dilogarithm mention to T176's principal polylogarithm definition, and added readable captions to the three existing Similar tables links. The candidate change was printed and read before submission. The authenticated API response reports `reviewed: false`, revision `6b936f9be0266c48e8b4cd44a2e87263475d5892a5093ced485cf7c2d43da65f`; it is preserved in `write-response.json`.

The post-write document equals the proposed document. All 54 values, their identities and order, parameter declarations, mathematical formulas, completeness, and programs are preserved; the formula's wording gained only the hyperlink. `generate.py`, `checks.py`, and `argument-selection.md` retain their reviewed bytes. No generator was rewritten or reattached.

Before editing, `agents/sage.sh` executed `repair-checks.py` with the existing attached generator and checker. All 54 stored decimals contain the computed finite positive Arb balls, with derived-angle uncertainty propagated. Independent integral quadrature at 115 and 135 decimal digits passed for every row; constant integration and Catalan identities passed as controls. The largest discrepancy was 0.499044482276 last-place units, and the smallest relative-radius accuracy was 122.26110282725426 decimal digits. The displayed Sage program was executed and agreed with the generator for all 54 inputs. These are reruns of the existing builder's independent numerical method, not a new independent critique. Full per-row evidence and the skill-manifest reference are in `repair-numerical-evidence.json`.

Reproduce with the three downloaded attachments together and `NUMBERDB_API_KEY` set for the private draft:

```
sage -python repair-checks.py
```

The actual sandbox command used the key on stdin:

```
cat "$NUMBERDB_KEY_FILE" | NUMBERDB_KEY_FROM_STDIN=1 agents/sage.sh "$TMPDIR/repair-checks.py" "$TMPDIR/generate.py" "$TMPDIR/checks.py"
```

Chromium rendered the fresh before/after server HTML with the site's scripts and styles. The repaired page has 53 MathJax containers, no math errors, no JavaScript errors, a working dilogarithm link, readable captions and no “Unknown key” warning. Screenshots, rendered text and dependency versions are retained in this work directory. Anonymous API/page reads conceal T611, confirming it remains private.

## Audit and independent-review boundary

The before/after API audits are identical: one existing family-selector warning, `clean: false`. No new audit finding was introduced. Both `antiprism` and `lobell` identify a geometric object whose hyperbolic volume is listed, with the same curvature and full reflection-group normalization. They do not select different invariants. The canonical skill expressly allows one invariant over different named objects; splitting or deleting either family is unwarranted.

A fresh independent critique is required before the controller can offer this same draft. The fingerprint includes all Formulas text, so even the justified dilogarithm hyperlink changes it:

- Before: `cfd06999902ccc14338835c16b46dce7826e33fe2624713c037703815dfc7787`.
- After: `0c64ae9bb4bdb8f210cb7d70004915bd8a080e03034a4e19bbe8baaaea9e5ab1`.

Both fingerprints came from `agents/argument_review.py fingerprint T611 --generator generate.py --generator checks.py --generator argument-selection.md`. The selected arguments and their mathematical definitions did not change. The reviewed attachment hashes are identical before and after.

`agents/critiques/T611-arguments.json` was neither edited nor accepted by this repair. Its unchanged SHA-256 is `52fce7a39df5e078002f21506a224db9e9b1ed72c603c856f1a98b3a3d44f0db`. Recover T611 for the separate critique; do not create a replacement draft. No controller checkpoint, completion receipt, or build handoff was written.
