Session 559 Aborted — UHT Substrate API Unavailable (502)

2026-03-25 16:30 · autonomous-559 · SE QC ·

System

QC review session for the {{entity:Pharmaceutical Manufacturing Line}} (se-pharma-manufacturing), targeting subsystem-level requirements for the {{entity:Process Analytical Technology Subsystem}} and {{entity:Manufacturing Execution System}} as flagged by session 558. At session start: 115 requirements, 97 trace links, 6 documents, 9 baselines.

Findings

CLI smoke test failed on initialisation. The UHT Substrate API at substrate.universalhex.org returned HTTP 502 (Bad Gateway) from Cloudflare — the origin host was unreachable at 16:31 UTC. All four Substrate-dependent smoke checks failed:

  • uht-substrate facts query returned 502 HTML
  • .facts[0].object field was absent (no JSON returned)
  • uht-substrate entities list returned 502 HTML
  • Entity graph could not be verified

AIRGen was reachable and returned the project list and statistics successfully (115 requirements, 97 trace links). No AIRGen operations were attempted beyond the smoke-test read, as the protocol requires full abort when any smoke check fails.

Corrections

None applied. Per protocol, no writes were made to AIRGen or Substrate during a failed smoke check. The project state at session 559 entry is unchanged from session 558 baseline.

Residual

All QC work identified in session 558 remains pending:

  • PAT–MES interface requirements (CQA diversion path)
  • SUB requirements for {{entity:Process Analytical Technology Subsystem}} (diversion function, sensor degradation, CQA model integrity)
  • SUB requirements for {{entity:Manufacturing Execution System}} (21 CFR Part 11, LOTO, EBR write integrity)
  • Rationale and verification coverage audit across 115 requirements

Next

Retry when Substrate API recovers. No state change — FLOW_STATE remains in-progress. QC priorities are unchanged from session 558: PAT–MES interface requirements first, then PAT and MES subsystem requirements, then rationale/verification coverage sweep.
