Root cause of the DSCA39 footer mismatch: the "Standard output load for test is
250 ohms." line is a footer note, not a parameter, but the STAGE 1 extractor
captured it as a (column-truncated) row "Standard output load for te". And the
renderer's OUTSIGTYPE==='CURRENT' emission was wrong on both ends — it printed the
note (after the underline, invisible to the validator gate) for many -C current
models whose staged originals never had it, and never placed it correctly for the
models that do.
Fix is data-driven, matching the rest of the template approach:
- derive-dsca-templates.js: detect the "Standard output load..." line, capture it
as a per-model `loadNote` property, and exclude it from rows. Regenerated
dsca-templates.json — surgically clean: only the 5 DSCA39 models changed (lost
the truncated row, gained loadNote); all 121 others byte-identical.
- datasheet-exact.js: emit `dscaTpl.loadNote` (blank line + note) before the footer
underline, only for models that have it; removed the OUTSIGTYPE-based emission.
STAGE 3 re-validation: FINAL-TEST CLEAN 85 -> 88, mismatches 9 -> 6, matches
2206 -> 2278. DSCA39-01/02/07 now fully clean; DSCA39-01 byte-content-verified.
No regression — the -C current models stayed clean and no longer carry the
spurious after-underline note.
The 6 remaining dirty models (DSCA38-05/-1793/-19C/-19E, DSCA39-05, DSCA39-1950)
are ALL retest data-vintage: the staged .TXT is an older test run than the DB
latest-wins record (Supply Current / Linearity differ by more than rounding).
Not render bugs — cannot be reconciled against an older sheet.

Remote SSH/VPN to AD2 keeps flapping; hand the remaining datasheet fixes to the
local AD2 session. Includes the per-subtype approach (DSCA_TEMPLATES from staged
originals — STAGE 1 done, dsca-templates.json on AD2 = 126 models), the render-wiring
+ per-subtype byte-validation gate, Fix 5 (379 backfill via legacy_cert_text), the
discipline (backup/save-state/validate-before-publish), and the derive-dsca-templates
tool. Ref ticket #32441.
