Test 171

Request

Inspect lantern#1864 and review its fallback for malformed customer chronology timestamps.

Required memory

Fact 258

For Harbor Health and Mosaic Commerce, customer-visible records now order only by authoritative `source_timestamp`; observation, serialization, processing, render, and retry times are non-ordering audit metadata, and a missing or malformed required source timestamp renders explicit unknown.

Iris confirmed that the corrected combined sentence describes sequence by authoritative source time without adding a causal, release-readiness, or employee-performance claim. Product Engineering has restored it for Harbor Health and Mosaic Commerce. Customer-visible records now order only by `source_timestamp`; observation, serialization, processing, render, and retry times remain non-ordering audit metadata, and a missing or malformed required source timestamp renders explicit unknown. All 64 regressions still pass, and I’ve closed only the triggered provenance review. Post the concise closure in #lantern, without implying any authorization expansion or release approval by me.
