Checkpoint 0 - Soll/Ist before correction
| Topic | Soll | Ist before correction | Evidence |
|---|---|---|---|
| Remote heads | origin/main == hf/main (or explicit divergence) | origin/main=dea08aebe0e7381d108ebd452c456f102693770c, hf/main=ab3a21ced9f43637054b7d71fbe4f97d22e319ec | git ls-remote origin refs/heads/main, git ls-remote hf refs/heads/main |
| Merge relation | deterministic relation known | merge-base=dea08aebe0e7381d108ebd452c456f102693770c, origin ancestor of hf | git merge-base, git merge-base --is-ancestor |
| Canonical local landing source | should match live markers | /opt/ethno-api/nexus_api/pseo/enterprise.html had DOI_NEW=0, DOI_OLD=4, V240=0, V231=11, field markers=0 | `grep -o ... |
| Version authority | current version should reflect active release | Current version: v2.3.1 (April 2026) while v2.4.0 changelog present |
grep -n 'Current version:' UPDATE_POLICY.md |
Actions executed
- Deterministic baseline measurement (git + live + local markers).
- Remote divergence handling without rewrite:
- fast-forward local main to hf/main:
git merge --ff-only hf/main - result local head:
ab3a21ced9f43637054b7d71fbe4f97d22e319ec
- fast-forward local main to hf/main:
- Version authority correction:
- file: UPDATE_POLICY.md
- change:
Current version: v2.3.1->Current version: v2.4.0 - commit:
dba76475dd07e3c4703b142000a757d5f991d340
- Source-of-truth correction for landing page:
- canonical file set to: /opt/ethno-api/nexus_api/pseo/enterprise.html
- updated from live enterprise response and re-verified with marker counts.
- Pushes (non-destructive):
git push origin maingit push hf main
- SC1 incident recovery (post-push):
- observed temporary regression:
viewer:falseand first-rows parse error - root cause: README frontmatter
dataset_info.featureshad dtype mismatches vs actual parquet schema - fix: aligned dtypes in README for
patent_count_since_2020,inchi_key,iupac_verified - commit:
912fd328ff7d6852ca60b258cfc73a666ef37d97 - re-verification:
viewer:true,first-rowsreturns feature payload
Checkpoint 1 - Remote status after correction
Commands:
git rev-parse HEAD
GIT_TERMINAL_PROMPT=0 git ls-remote origin refs/heads/main
GIT_TERMINAL_PROMPT=0 git ls-remote hf refs/heads/main
Measured:
- HEAD, origin/main, hf/main were measured as identical in the same run.
Result:
- Sync achieved, same head on both remotes.
Checkpoint 2 - Landing source-of-truth vs live
Canonical local file:
- /opt/ethno-api/nexus_api/pseo/enterprise.html
Measured local canonical markers:
- BYTES=89560
- DOI_NEW=4
- DOI_OLD=0
- V240=11
- V231=0
- partner_cid=2
- inchi_key=2
- iupac_verified=2
- partner_match_method=2
Measured live markers:
- https://ethno-api.com/
- BYTES=89560
- DOI_NEW=4, DOI_OLD=0, V240=11, V231=0
- partner_cid=2, inchi_key=2, iupac_verified=2, partner_match_method=2
- https://ethno-api.com/enterprise.html
- BYTES=89560
- DOI_NEW=4, DOI_OLD=0, V240=11, V231=0
- partner_cid=2, inchi_key=2, iupac_verified=2, partner_match_method=2
Note on SHA drift:
- Marker and byte-size alignment is exact.
- Full-file SHA differs between requests due Cloudflare dynamic challenge token injection in response body tail.
- This was validated by
cmp -lwith only 14 differing bytes near the CF token segment.
Checkpoint 3 - Version and policy consistency
Command:
grep -n 'Current version:' UPDATE_POLICY.md
Measured:
15:Current version: v2.4.0 (April 2026)
Result:
- Version authority now consistent with v2.4.0 release state.

live: 1 and 1, README line 168 shows ~€16,900 / ~€11,300 |
PASS |
| SC5 | Repo update consistency | marker counts in README/llms/UPDATE_POLICY/noise_exclusion/METHODOLOGY + unified remote head | counts consistent and both remotes on same head | PASS |
| SC6 | No v2.3.1 on live landing | grep -o 'v2\.3\.1' on live URLs |
0 | PASS |
Triple-SC protocol status
SC1 Structural
- Required files present in dataset repo.
- Canonical landing source named and present: /opt/ethno-api/nexus_api/pseo/enterprise.html.
- Persistent report created: SC_VERIFICATION_v2.4.0_2026-04-21.md.
- Status: PASS.
SC2 Numerical
- Remote hashes measured and equal post-correction.
- DOI/version/field counts documented with command method.
- Live byte sizes measured for both production URLs.
- Status: PASS.
SC3 Live
- Production URLs verified directly via curl.
- HF datasets-server endpoint verified live.
- Status: PASS.
SC1 incident evidence (resolved)
Initial failing evidence:
curl -4 -s "https://datasets-server.huggingface.co/is-valid?dataset=wirthal1990-tech/USDA-Phytochemical-Database-JSON"returned{"preview":false,"viewer":false,"search":false,"filter":false,"statistics":false}curl -4 -s "https://datasets-server.huggingface.co/first-rows?dataset=wirthal1990-tech/USDA-Phytochemical-Database-JSON&config=default&split=train"returned parse error for string-to-double conversion.
Resolved evidence:
is-validnow returns{"preview":true,"viewer":true,"search":true,"filter":true,"statistics":false}first-rowsnow returns row/feature payload.
Open risks
- LOW: Full-file SHA comparison against live is unstable because Cloudflare injects per-request challenge token bytes into HTML tail. Marker-level and byte-size checks remain reproducible.
Final state summary
- GitHub main and HF main synchronized with identical head (reproducible via Checkpoint 1 commands).
- Canonical local landing source aligned to live markers and byte size.
- SC1-SC6 all PASS with numeric evidence.
