Records/npm/typescript/failure issue

Where it was measured

PASS means the release recorded a passing observation at PROJECT_PROCESS 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 PASS 48 passing observations
• 6.0.3 FAIL
• 5.9.3 FAIL
• 5.8.2 PASS 10 passing observations
• 5.7.3 PASS 12 passing observations

Where it reproduced

• executionContext=node · moduleSystem=esm · os=windows · runtime=node@24.13 ×43 2026-09-26 → 2026-09-26
• executionContext=node · moduleSystem=cjs · os=linux · runtime=node@22.23 ×1 2026-08-23 → 2026-08-23

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 5.8.2 → first failing release 5.9.3

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

• Last failing release 6.0.3 → first passing release 7.0.2

  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.
• No failure domain was inferred for this failure.
