Records/npm/typescript/failure issue

Where it was measured

PASS means the release recorded a passing observation at PROJECT_TYPECHECK and no record of this failure. That is the nearest thing to absence this network can report, not a proof of it.

• 7.0.2 FAIL
• 6.0.3 not measured
• 5.9.3 FAIL
• 5.8.2 not measured
• 5.7.3 PASS 1 passing observations

Nearest known PASS/FAIL boundaries

The two adjacent releases the verdict changes across. Releases nothing measured do not close the gap; they are counted instead.

• Last passing release 5.7.3 → first failing release 5.9.3

  Releases between them never measured at this stage: 1

  Both trees resolved every dependency to the same version. Nothing here moved.

Evidence gaps

• The evidence for this failure was not preserved, so it has no established cause. Its stored hash is provenance, not an identity.
• Releases in this window never measured at PROJECT_TYPECHECK: 2
• No failure domain was inferred for this failure.
