description: DSCA33/45 "lost spec files" are recoverable from the Hoffman API (original certs survived the wipe) — do NOT request spec files from John; mine templates from Hoffman instead
metadata:
  type: project
---

The DSCA33/DSCA45 main spec files lost in Dataforth's cryptolocker wipe (which blocked rendering
~8,763 certs and prompted "ask John for the spec files") are **recoverable** — the original software
published correct DSCA33/45 certs to the **Hoffman API** before the wipe, and our null-skipping
pipeline never overwrote them. **Do not ask John for spec files.** Supersedes the FIX2-5 handoff's
TODO 2 and the `ad2`-branch memory `project_dsca33_45_spec_gap` (which says "blocked, need John").

Mined **56 of 58 models** straight from Hoffman into `projects/dataforth-dos/dsca33-45-templates.json`
(per model: `accOut`, verbatim 2-line `accHeader`, Final-Test `rows` of name+spec, and a known-good
`_srcSerial`). Only 2 niche models have no original anywhere: **DSCA33-1948 (16u)**, **DSCA45-1746 (8u)**.
Coverage: ~7,157 units already correct + live on Hoffman (no action); ~1,580 not-yet-uploaded units
need rendering from the mined templates + AD2's already-derived slotMaps.

**STATUS — DONE on AD2 (2026-06-18, commits up to `4615877f` on `ad2`):** the AD2 session wired the
mined templates into the renderer, reverse-engineered the DSCA33/45 accuracy-block formatting, and
published the gap. **54 of 56 models validated byte-for-byte vs the live Hoffman originals** and
marked `validated:true` in `dsca33-45-templates.json` (the per-model render gate — a model renders
only when validated). **1,452 truly-new certs published to Hoffman (created=1452, updated=0,
errors=0)** — published absent-only (probed each serial with a GET; the stale inventory means
`api_uploaded_at IS NULL` does NOT mean "absent from Hoffman", so never trust it for this) so ZERO
originals were overwritten. Still null/unpublished: **DSCA33-04A** + **DSCA33-1891** (each one accuracy
cert at a rounding boundary where `Math.fround` rounds opposite the original — left UNvalidated), and
the 2 no-original models **DSCA33-1948 / DSCA45-1746** (24 units). The 126 already-live gap units were
left untouched.

Render specifics now in `templates/datasheet-exact.js`: DSCA3345_TEMPLATES takes precedence over the
stale staged-extraction entries; `formatAccuracyLineDSCA3345` (mADC calc stored in A -> x1000; DSCA33
meas unscaled, DSCA45 meas scaled; DSCA33 unsigned stim/calc/meas, DSCA45 signed + integer-Hz stim;
fround); leading-zero drop only when the value overflows the 6-char field; DSCA33 "Check List" header;
section sub-heads (Zero-Crossing/TTL) get no status. Tools: `validate-dsca3345.js` (oracle gate),
`slotmap-from-hoffman.js`, `publish-dsca3345-gap.js`.

Handoff doc (historical): `projects/dataforth-dos/DSCA33-45-HOFFMAN-RECOVERY-2026-06-18.md`. Hoffman
read API: `GET https://www.dataforth.com/api/v1/TestReportDataFiles/{serial}`; creds vault
`clients/dataforth/hoffman-product-api` (on AD2 the deployed uploader token at
`C:\ProgramData\dataforth-uploader\credentials.json` works for reads too — no vault needed). Miner:
`projects/dataforth-dos/tools/mine-hoffman-dsca.py`. AD2 access notes: [[ad2-ssh-mtu-blackhole]],
