# T624 editorial repair, 20261030T113658Z
Both findings were present in fresh authenticated API and rendered-page reads.
T624 was private before and after the edit, as checked by comparing anonymous
and authenticated API access. The API revision is
`1739dea7cb54c1891ec00a0ff760ba750f63c91c5b0713d9cea7c09866abbf9b`;
the response states `reviewed: false`.
The edit removes only `Data properties.digits`, which the page displayed as
`digits: 100 (Unknown key)`, and wraps the first Comments mention of unit sphere
in `HREF{Volume_of_the_unit_sphere}[unit sphere]`. The target was read live and
is T28, the volume of the unit d-sphere in Euclidean (d+1)-space. For a single
column, Q*Q=1 is the unit-sphere condition and the Frobenius metric is the
ordinary Euclidean metric, in real dimension n or 2n. Thus the existing sentence
and the family link use the same sphere and metric convention.
All 272 stored values, their order, parameter declarations, mathematical
statements, completeness note, program and generator are unchanged. The
precision explanation remains in rigour details, and the generator retains
`digits = 100`. No new values were supplied. The original generator remains at
SHA-256 `2586de8f49b2842b0b565b1eede547105b4871f807e1d01d07fcfc090d4c8966`.
## Checks and reproduction
Download `repair_check.py`, `document-before.json`, `sphere-document.json` and
the existing `generate.py` into one directory. With SageMath and numberdb:
```
sage -python repair_check.py
```
For this campaign the executed command, from the source-snapshot root, was:
```
agents/sage.sh "$TMPDIR/repair_check.py" "$TMPDIR/document-before.json" \
"$TMPDIR/sphere-document.json" "$TMPDIR/generate.py" \
> "$TMPDIR/numerical-repair-results.json"
```
The checker uses direct Gamma products at 600 bits, a separate numerical route
from the generator's exact sphere recurrence. It does not constitute a separate
proof of the volume theorem or a new independent campaign critique. It checks
271 approximate stored intervals by full ball containment and the exact integer
2 separately. All 272 generating values also fit their stored representations.
Every one of the 32 one-column cases agrees with the live sphere table; all
parameter identities agree with the unchanged default enumeration. Inputs are
exact integers and half-integers and Arb propagates arithmetic uncertainty.
Minimum relative accuracy: 591 bits for the direct calculation, 389 bits for
the generator. Three known-answer controls and a corruption control pass.
Sage 10.9 and numberdb 0.1.10 were used. Full results are attached as
`numerical-repair-results.json`.
The Chromium check confirms the unknown-property diagnostic is gone and the
Comments family link is present, with no MathJax or page errors. Playwright
1.64.1 and Chromium 156.0.8078.4 were used. The API audit still has exactly its
original named-field warning and no new findings. The two field names select
frame spaces, while every row measures their volume in the specified metric;
this warning does not justify splitting the declared family.
## Skill evidence and controller handoff
The governing archive is
`agents/runs/20261030T113658Z-repair-skills/manifest.json`, whose SHA-256 is
`f3ffe644f05a2d8ba38978976adde3737ab5de3d1ebeb214066f311233b3080e`.
Both `skill-local.md` and `skill-live.md` were read and each hashes to
`28ecbeeccb0c5e5d6eb541b5a5b0f88aec47b154374d909085116d34f5629199`.
The canonical source copy matches. The archived policy governs this run.
The Comments link changes the version-1 selection fingerprint from
`c1b8ba1efd4372abe5e437a22acb08df1135d0d8f0cae4a1bb21fecf734c0f7e` to
`33c9a4db7aab2f738c4f39b9c09f6cbd6f0de0e7f0a197821adba5c6ec365f1d`.
A fresh independent critique is required for this same draft. The independent
`agents/critiques/T624-arguments.json` was not rewritten or accepted by this
repair actor; its bytes still hash to
`12a1adeb386acea4007535a8d89f731259394b450ca47d8dde1541334d00a8b0`.
No reviewed generator source changed. No offer, publication or review action
was taken. The controller retains the same T624 draft.
Local evidence is in `agents/runs/20261030T113658Z-repair-work/`, including the
before/after documents and HTML, rendered text, screenshots, numerical script
and outputs, diff, API results and audit. Three initial checker diagnostics
are retained; no failed check was treated as a passing verification.
