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Cleanups: deleted superseded memory project_dsca33_45_spec_gap; struck the obsolete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.

Some DSCA subtypes' raw_data STATUS groups carry more (or fewer) value-bearing
entries than the template's spec-bearing rows (the test program measures slots the
printed sheet omits, e.g. DSCA49's 5mA load pair), so the in-order zip misaligned
values and those models were skipped by the count-guard.
New tool derive-dsca-slotmaps.js derives a per-model slotMap (absolute statusEntries
index per spec-bearing row) by greedily matching a staged original's printed values
to the DB raw_data STATUS entries (same fround formatting), then picking the
candidate map that validates against the most units. Models are grouped by identical
row-name signature and one map is derived per group from all sibling units — this
disambiguates duplicate values (e.g. a unit where 5mA != 50mA linearity forces the
correct slot; DSCA49-04 alone has only 2 staged units that can't, but its siblings'
25 units do). Stored as `slotMap` in dsca-templates.json.
Renderer: consults slotMap only when the sequential zip fails (value count !=
spec-row count), so the 88 already-clean models keep their path (no regression) and
ambiguous ones pull the right value via the map.
STAGE 3 re-validation: FINAL-TEST CLEAN 88 -> 92; 134 more certs now render
(null 450 -> 316); matches 2278 -> 2412. Same 6 retest-vintage dirty models, no
new mismatches. DSCA49 family + DSCA40-03 group now clean and validated.
Still blocked (separate gap, NOT layout ambiguity): DSCA45-* and most DSCA33-*
render null because they have NO spec-reader entries (render-datasheet bails before
rendering). Their slotMaps are derived and ready; they need spec coverage. One DSCA33
group (DSCA33-02/03/03A/04/05/1948) did not reach the slotMap validation threshold
(best 19/35 units) and stays skipped pending more/cleaner staged samples.
