dataforth/dsca33-45: recover lost specs from Hoffman API (56/58 models)

The DSCA33/DSCA45 main spec files lost in the cryptolocker wipe are recoverable:
the original software published correct certs to the Hoffman product API before
the wipe and our null-skipping renderer never overwrote them. Mine per-model
Final-Test templates (names + specs + verbatim accuracy headers) straight from
those originals instead of requesting spec files from Dataforth/John.

- dsca33-45-templates.json: 56 models (DSCA33 34/35, DSCA45 22/23); only
  DSCA33-1948 + DSCA45-1746 (24 units) lack an original.
- mine-hoffman-dsca.py: the re-runnable miner.
- DSCA33-45-HOFFMAN-RECOVERY handoff for the AD2 session (incl. the gate:
  validate each render vs its Hoffman original before enabling live rendering).
- memories: Hoffman recovery (supersedes the spec-gap "need John" note) and the
  AD2 SSH MTU-blackhole root cause/fix; errorlog entries (syncro jq, ssh correction).

+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.
+
+AD2 handoff + the critical gate: `projects/dataforth-dos/DSCA33-45-HOFFMAN-RECOVERY-2026-06-18.md`.
+**Critical:** validate each model's render byte-for-byte against its Hoffman original BEFORE enabling
+live DSCA33/45 rendering — once the renderer returns non-null, the pipeline stops skipping these and
+will re-push/UPDATE the 7,157 good originals on the next cycle (safe only if the render matches).

+Hoffman read API: `GET https://www.dataforth.com/api/v1/TestReportDataFiles/{serial}` (returns
+`{SerialNumber,Content,CreatedAtUtc,UpdatedAtUtc}`); creds vault `clients/dataforth/hoffman-product-api`.
+Miner: `projects/dataforth-dos/tools/mine-hoffman-dsca.py`. AD2 access notes: [[ad2-ssh-mtu-blackhole]].
