Buyer-visible scope

This Draft repairs deterministic and accessible Event Lineage presentation without changing lineage truth, persistence, provenance, inference semantics, or domain identity.

The candidate keeps locale-independent reconstruct-group ordering; literal Ungrouped identity distinct from truly ungrouped records; input-order-independent node/edge layout; deterministic parallel-edge selection; locale-safe accessible disambiguation; offset-aware UTC ordering; stable selection across unrelated rerenders; pointer/touch acquisition for thin SVG edges; deterministic evidence-table ordering by domain evidence rank; and fail-closed duplicate canonical node identity, visible self-loops, and visible same-group directed cycles.

Material-UI acceptance remains exact-head scoped. Predecessor local/hosted Storybook or Chromium evidence is not transferred after head movement.

These guards are presentation fail-closed behavior only. They create no synthetic node identity, replacement relationship, or new lineage fact.

Protected-main convergence

Fresh review 5116222327 found that the branch still diverged from protected main@83eba56149eb802cd63642c507c324c9976ec78e by six commits. The intervening protected delta is #931's repository-local Draft-admission repair and touches only .github/workflows/{tests,prov-o-contract,ontology-pages}.yml plus tests/test_tests_workflow_contract.py; PR #903's 17 product/UI changed files are disjoint.

The branch was repaired non-destructively at e325b3f63fdb9c34a7c62ae58045ec36e34b1879: exact protected blobs for those four files were adopted and a two-parent commit preserved both histories. No force-push, destructive rebase, gate weakening, or product-delta rewrite was used.

Exact live boundary

• protected base: main@83eba56149eb802cd63642c507c324c9976ec78e
• exact current head: e325b3f63fdb9c34a7c62ae58045ec36e34b1879
• PR: open / Draft / mechanically mergeable
• live ancestry: protected main is a parent of the current head; predecessor b0e94aa… base evidence is superseded
• repository-local exact-head Tests 33902540271: completed skipped under the protected Draft-admission contract
• central exact-head CodeQL 33902540239, Security 33902540308, SAST 33902540204: queued at this snapshot
• exact-head product GREEN: not claimed
• qualifying independent current-head APPROVE: none established in this convergence step

Keep Draft. Re-establish current-head Storybook/Chromium desktop/mobile, responsive overflow, pointer/touch, keyboard/focus and accessibility evidence when the review lane is admitted; predecessor browser/check/review results do not transfer.

Documentation evidence boundary

docs/product-technical-gap-baseline.md contains dated historical overlays. Its older b0e94aa… #903 snapshot is retained as historical evidence, not treated as the current live authority; this PR body and GitHub exact refs are the current delivery boundary until a non-destructive baseline overlay can supersede it without rewriting historical evidence.

Fresh protected-main review found the branch still diverged from main@83eba56149eb802cd63642c507c324c9976ec78e by the six protected commits that introduced #931's repository-local Draft admission contract. The PR's 17 product/UI changed files do not overlap the four protected workflow/contract files, so leaving it on b0e94aa… would make the branch carry a stale CI contract and stale base evidence. Repaired non-destructively at e325b3f63fdb9c34a7c62ae58045ec36e34b1879: exact protected blobs for Tests/PROV-O/Ontology and tests/test_tests_workflow_contract.py were adopted, then a two-parent merge commit preserved both histories. No force-push/rebase or product delta rewrite. Current-head hosted gates and browser/a11y evidence must be re-established; predecessor evidence does not transfer.
