test(zigux): add lane28 heptaconta weave clasp replay

[adybag14-cyber]

Summary

• add a bounded Lane 28 Phase 3 list/hlist replay for a seventy-node heptaconta weave-clasp route
• route visible nodes as 69 -> 0 -> 44 -> 43 -> 68 -> 1 -> ... -> 56 -> 31 -> 30 -> 13 -> 29 -> 28 -> ... -> 14, with one detached exclusion entry
• prove forward ListView / HListView traversal, membership, first/last anchors, hlist tail-null state, route uniqueness, and staged list backlink / hlist pprev repair at route index 50
• add a standalone build shard exposing phase3-list-hlist-heptaconta-weave-clasp-replay, test, and the default build route

Why This Lane

• Lane 28 owns the Phase 3 list and hlist interop slice
• current same-lane replay front is active through PR test(zigux): add lane28 enneahexaconta weave clasp replay #23117 / the sixty-nine-node enneahexaconta weave-clasp route plus earlier list/hlist surfaces
• authenticated target-path checks returned 404 on master, and exact PR/code searches found no heptaconta, hebdomeconta, or hebdomaconta owner before publication
• this stays additive and non-conflicting under zigux/tests/, avoiding helper bodies, shared build roots, fixtures, scripts, docs, workflows, Makefiles, ABI surfaces, UAPI, and neighboring Phase 3 lanes

Validation

Focused validation used attached Zig 0.17.0-dev.87+9b177a7d2 in a compact helper validation root. Helper API mirrors were grounded by authenticated current master reads of zigux/helpers/list_view.zig and zigux/helpers/hlist_view.zig because direct live checkout is not available in this scheduled runtime.

Passed:

• zig version: 0.17.0-dev.87+9b177a7d2
• zig fmt --check zigux/helpers/list_view.zig zigux/helpers/hlist_view.zig zigux/tests/phase3_list_hlist_heptaconta_weave_clasp_replay.zig zigux/tests/phase3_list_hlist_heptaconta_weave_clasp_replay_build.zig
• compact helper mirror tests: list helper 1/1, hlist helper 1/1
• direct proof test with explicit helper modules: All 2 tests passed.
• build-step listing exposed phase3-list-hlist-heptaconta-weave-clasp-replay and test
• named route: Build Summary: 3/3 steps succeeded; 2/2 tests passed
• test route: Build Summary: 3/3 steps succeeded; 2/2 tests passed
• default route: Build Summary: 3/3 steps succeeded; 2/2 tests passed
• ASCII scan found no non-ASCII bytes in the two new replay files and compact helper overlay

Validation note: an initial direct zig test CLI form hit the known Zig 0.17 module-argument limitation (main module provided both... / module 'root' declared but not used); the corrected --dep ... -Mroot=... form passed.

Scope

• lane: Lane 28 -- Phase 3 list and hlist interop slice
• files:
  • zigux/tests/phase3_list_hlist_heptaconta_weave_clasp_replay.zig
  • zigux/tests/phase3_list_hlist_heptaconta_weave_clasp_replay_build.zig

Validation Boundary

CI/review is the first exact full live-tree execution against complete current repository files. Local execution used compact current-helper mirrors while live grounding, absence checks, publication, readback, and compare used authenticated GitHub connector operations.
