Replace unhealthy GLM route with Novita

[nedcut]

What changed

• replace the unhealthy first-party Z.AI FP8 GLM 5.2 route with the exact Novita FP8 endpoint
• record the clean replacement smoke and retire the superseded Z.AI manifest entry
• refresh exact-route pricing, runtime evidence, cost estimates, readiness notes, and leaderboard metadata
• add a registry regression assertion for the amended route

Why

Repeated full-panel preflights found OpenRouter's pinned z-ai/fp8 endpoint at status -2. The exact dated novita/fp8 endpoint was healthy, supported the frozen lane parameters, and serves the same GLM 5.2 snapshot. No full-panel GLM result existed, so the route could be amended without replacing observed panel data.

The replacement smoke completed 4/4 decisions with zero failures, zero truncations, exact Novita provenance, and $0.009225 spend. The empirical ten-route panel estimate is now $46.7742, with the operator spend ceiling remaining authoritative.

Validation

• replacement endpoint preflight passed
• replacement smoke passed: 4/4 decisions, zero failures/truncations
• complete 10-route no-spend panel preflight passed
• python3 -m pytest -q — 458 passed
• Ruff format and lint passed
• python3 -m gm_bench validate-contract passed
• web lint and production build passed

📝 Walkthrough

Walkthrough

The frozen OpenRouter GLM 5.2 route changes from Z.AI FP8 to Novita FP8. Registry, smoke manifest, leaderboard, runtime pricing, cost estimates, publication readiness, run logs, and consistency tests are updated accordingly.

Changes

GLM 5.2 route amendment

Layer / File(s)	Summary
Route registry and smoke identity config/sota_v2_models.json, config/sota_v2_smoke_manifest.json, web/src/data/leaderboard.json, tests/test_publication.py	The GLM 5.2 registry and required smoke identifier now use the Novita FP8 route, with updated manifest artifacts, endpoint metadata, leaderboard identity, and publication assertions.
Runtime pricing and cost estimates config/openrouter_pricing_snapshot.json, results/analysis/output-budget-cost-estimate.json	Runtime timestamps, observed latency, pricing rates, per-model costs, aggregate budget figures, and observation sources are refreshed for the Novita amendment.
Publication readiness evidence docs/PUBLISH_READINESS.md, docs/run_logs/*	Publication status, decision history, route-amendment evidence, and smoke campaign spend accounting now describe the accepted Novita route and replacement smoke.
