Per the 5070 handoff (DSCA33-45-HOFFMAN-RECOVERY): the lost DSCA33/45 specs are
recoverable from Hoffman, not John. Wired the mined dsca33-45-templates.json (56
models) into the renderer:
- datasheet-exact.js: load DSCA3345_TEMPLATES; for family DSCA, the Hoffman-mined
template takes PRECEDENCE over the stale staged-extraction entry (which shadowed 25
models with accOut "?"/no accHeader). Emit the verbatim 2-line accHeader for these
families (Vin (mVAC)/Iin (AAC)/Frequency (Hz), Output (VDC)/(mADC)). Per-model
`validated` GATE: a DSCA33/45 model renders only after byte-matching its Hoffman
original; until then it returns null (skipped) so an unverified render can never
overwrite a pristine live original. DSCA_VALIDATE_MODE env opens the gate for the
validation harness only. Exposed rendersWithoutSpecs().
- render-datasheet.js: allow a null-specs render for DSCA33/45 (their spec files were
lost; template-driven) instead of bailing on missing specs.
- derive-dsca-slotmaps.js: DSCA_TPL env to target the 3345 templates; derived 43 slot
maps into them (22 models need none, 8 DSCA33 still below threshold).
- validate-dsca3345.js (new): renders each model's _srcSerial, fetches the live
Hoffman original (GET TestReportDataFiles/{serial}, deployed uploader token — no
vault needed), content-normalized compare; --apply marks validated.
STATUS: gate is CLOSED — 0 models validated, all DSCA33/45 still render null, nothing
published, no risk. Final-Test block + accuracy headers now byte-match the Hoffman
originals for all 56 models; the remaining blocker is accuracy-DATA numeric quirks that
must match to pass the gate:
- DSCA33 calc column stored in A but displayed in mADC (x1000); measured stored in
mA (not scaled) — an original-software unit quirk.
- sign conventions differ per layout (DSCA33 stim/calc/meas unsigned, error signed;
DSCA45 stim unsigned, calc/meas/error signed).
- DSCA45 frequency-input stim formatting.
These need per-layout reverse-engineering against the originals (the validation harness
is the oracle). 8 DSCA33 models (DSCA33-02/03/03A/04/04A/05/05A/1642) also lack a slot
map (below threshold). DSCA33-1948 + DSCA45-1746 (24 units) have no Hoffman original.
Cleanups: deleted superseded memory project_dsca33_45_spec_gap; struck the obsolete
"ask John" TODO 2 from the handoff note.

Extends the Test Datasheet Pipeline on AD2:C:\Shares\testdatadb to
generate web-published datasheets for the SCMVAS-Mxxx (obsolete) and
SCMHVAS-Mxxxx (replacement) High Voltage Input Module product lines.
Both are tested either with the existing TESTHV3 software (production
VASLOG .DAT logs) or in Engineering with plain .txt output.
Key changes on AD2 (all deployed 2026-04-12 with dated backups):
- parsers/spec-reader.js: getSpecs() returns a `{_family:'SCMVAS',
_noSpecs:true}` sentinel for SCMVAS/SCMHVAS/VAS-M/HVAS-M model prefixes
so the export pipeline does not silently skip them for missing specs.
- templates/datasheet-exact.js: new Accuracy-only template branch
(generateSCMVASDatasheet + helpers) that mirrors the existing shipped
format byte-for-byte. Extraction regex covers both QuickBASIC STR$()
output formats: scientific-with-trailing-status-digit (98.4% of
records) and plain-decimal (1.6% of records above QB's threshold).
- parsers/vaslog-engtxt.js (new): parses the Engineering-Tested .txt
files in TS-3R\LOGS\VASLOG\VASLOG - Engineering Tested\. Filename SN
regex strips optional trailing 14-digit timestamp; in-file "SN:"
header is the authoritative source when the filename is malformed.
- database/import.js: LOG_TYPES grows a VASLOG_ENG entry with
subfolder + recursive flags. Pre-existing 7 log types keep their
implicit recursive=true behaviour (config.recursive !== false).
importFiles() routes VASLOG_ENG paths before the generic loop so a
VASLOG - Engineering Tested/*.txt path does not mis-dispatch to the
multiline parser.
- database/export-datasheets.js: VASLOG_ENG records are written
verbatim via fs.copyFileSync(source_file, For_Web/<SN>.TXT) for true
byte-level pass-through, with a graceful raw_data fallback when the
source file is no longer on disk.
Deploy outcome:
- 27,503 SCMVAS/SCMHVAS datasheets rendered (27,065 from scientific +
438 from plain-decimal PASS lines, post-patch rerun)
- 434 Engineering-Tested .txt files pass-through-copied to For_Web
- 0 errors across both batches
Repo layout added here:
- scmvas-hvas-research/: discovery artifacts (source .BAS, hvin.dat,
sample .DAT + .txt, binary-format notes, IMPLEMENTATION_PLAN.md)
- implementation/: staged final code + deploy helpers + local test
harness + per-step verification scripts
- backups/pre-deploy-20260412/: independent local snapshot of the 4
AD2 files replaced, pulled byte-for-byte before deploy
All helper scripts fetch the AD2 password at runtime from the SOPS
vault (clients/dataforth/ad2.sops.yaml). None of the committed files
contain the plaintext credential. Known vault-entry hygiene issue
(stale shell-escape backslash before the `!`) is documented in the
fetcher comments and stripped at read-time; flagged separately for
cleanup.
