# T558 build handoff

Completed the existing T558 draft with exact S_n(x;m), n=0,...,5, where
m is the literature parameter mu. The generator retains its original monic
recurrence algorithm and intended six-entry range, with the parser-compatible
variable name and additive fill behavior. No parameter identities changed.

All six values passed generator.verify(sample=None), the independent
Wronskian construction and symbolic identities on live API readback. The
stored program ran and agreed. The final audit is clean. Browser MathJax
rendering has no errors or unknown-key warning. See numerical-evidence.json,
sources-checked.md, argument-selection.md, and attached reproducibility files.

The source snapshot and archived skills agree; the authoritative manifest is
agents/runs/20261028T224818Z-repair-skills/manifest.json. Both local and live
SHA-256: 28ecbeeccb0c5e5d6eb541b5a5b0f88aec47b154374d909085116d34f5629199.

Fresh independent critique is required because the empty selection, prose and
generator source changed. No argument-review sidecar was written or accepted.
The controller must recover T558 itself. Nothing was offered, published,
reviewed, committed, pushed, or deployed. Old revisions and attachments are
preserved; current document.json and numerical-evidence.json supersede the
previous blocked-build snapshots. The run's native research and logs remain in
agents/runs/20261028T224818Z-repair-work/.
