Problem and resulting behavior

Fixes #8951. When existing creation clocks are missing, environment-build treated an unknown comparison as evidence that IDs were random, changing learned create insertion from ascending ID to append. The shared randomIdentities evidence owner now requires a witnessed inversion among canonical clock readings. Missing or invalid observations do not hide inversions between the remaining known values; seconds/milliseconds and submillisecond precision compare as instants.

The concrete Greptile P1 on the first head exposed an inversion across a missing middle clock. The repair is delivered in a3e16d1 and also covers invalid text and mixed-unit gaps. UUID-v4 classification, all-clock qualification, the exported comparator, insertion candidate ranking, generators, later-list checks, refusal/rollback, responses and cleanup retain their owners and behavior. No new parser/schema/dependency, target execution or retry/timeout changes.

Own real CLI reproduction was recorded in issue comment6648112176 before implementation. Related production sort-learning changes were read; no other same-root public implementation was found at publication. No foreign runtime is used as validation.

Validation

• Final eight complete focused files:308PASS; fresh README9 => nine distinct317PASS0skip. Six real HTTP MCP scenarios create three items and read a six-item list; their24 calls are within those six tests. Existing write validation and rollback consumers are included.
• Seven immutable HAR cases through actual compiled and normally installed public CLIs:14 calls per product. Source hashes unchanged; controls and gap outcomes match. These calls are separate from the317 tests.
• Full check, docs, discovery3029files exactly once, explicit pack dryrun and official installed-package verification passed:234tools/sixprompts, exact6.8.0 update, verified process lineage and awaitedcleanup. All2781 archive/current/installed published files match.
• Independent frozen-package Standards and Spec v6 both PASS. Earlier failed probes/reviews are retained; their counts are not added to final results.

macOS arm64, Node24.22.1. Captures are locally generated offline HAR inputs with real local HTTP serving; external application/browser capture, complete provider/agent/model workflows, other hosts and performance were not run. Current repaired-head upstream CI/Codex remains separate from these local results. No migration or breaking schema change.

Confidence Score: 5/5

[Medium impact] The PR appears safe to merge; the previous ordering defect is fixed and no new blocking issues were found.

Summary

Keeps ID ordering when captured clocks are missing, while still recognizing real inversions across gaps.

• Missing clocks no longer make ordered IDs look random.
