chore: publish the 84% savings figure everywhere, and drop the delisted nemotron-3-nano-30b

[VickyXAI]

Sources, fetched 2026-09-29: blockrun.ai/brand/numbers.json has savings = {baselineModel: anthropic/claude-opus-5, autoVsBaselinePct: 84, ecoVsBaselinePct: 98} and models.free = 6. The live free chat set in /api/v1/models is nemotron-3-nano-omni-30b-a3b-reasoning, nemotron-3.5-lightning, llama-3.2-11b-vision, nemotron-3-ultra-550b, north-mini-code and laguna-xs-2.1.

Depends on BlockRunAI/router-core#3. This PR pins @blockrun/router-core to that PR's head, e38958b. Merge router-core#3 with a merge commit so the SHA stays on main. GitHub's squash and rebase both write new SHAs, and then this pin would need to move to whatever lands.

Savings claims

Where	Old	New	Why
src/index.ts header comment	78% cost savings	84%	Published auto figure
src/index.ts plugin description	78% cost savings	84%	Same
openclaw.plugin.json description	92% cost savings	84%	Same. The copy is unqualified, so it gets the auto figure, not eco's 98.
src/router/brand-numbers.test.ts	—	new plugin descriptions block	Neither file can hold a marker. The test asserts every NN% cost savings in each file equals savings.autoVsBaselinePct, and that at least one exists. I checked that it fails on the old literals and passes on the new ones.

Every markdown claim already used <!-- br:savings.* --> markers and reads 84/98 (sync-brand-numbers.mjs --check: up to date).

Delisted free model nemotron-3-nano-30b

blockrun delisted it on 2026-09-08: NVIDIA deprovisioned it for the account, and the gateway redirects it to nano-omni. Startup logged it as unserved and skipped it on every boot.

Where	Old	New	Why
src/proxy.ts FREE_MODELS	7 rungs, nano-30b at #2	6 rungs, same relative order	Dead rung. The order comment is renumbered and records the delisting.
src/top-models.json	lists it	removed	The picker must only show live models
src/models.ts aliases nano-30b, nemotron-nano-30b, nvidia/nemotron-3-nano-30b, nemotron-nano, nemotron-nano-9b	→ free/nemotron-3-nano-30b	→ free/nemotron-3-nano-omni-30b-a3b-reasoning	Follows the gateway's own redirect target (both redirect tables, fallbackModel, savings-mix.json eco.SIMPLE). It is the same family and size (30B-A3B). I retargeted rather than deleted, so the published clawrouter.aliases = 259 still holds.
src/models.ts catalog entry	"fastest free model"	kept, marked DELISTED	Same convention as the other retired free ids (step-3.7-flash, nano-9b-v2 and others): explicit pins stay routable, and it is off the picker and the cascade.
@blockrun/router-core pin	5ee7c23	e38958b	eco SIMPLE fallback[0] goes nano-30b → nano-omni, and nano-omni is marked supportsVision:false, so image turns still skip that rung. free-model-liveness.test.ts failed on the old pin once nano-30b left the picker, which is what that guard is for.
src/router/free-model-liveness.test.ts	—	named regression	No router rung and no alias target may name nano-30b
src/models.test.ts reasoning-flag list	nano-30b	nano-omni	The list is meant to cover live models
README.md	pricing-table row, "other six as fallbacks", /model nano-30b hint, FAQ list	row removed, "other five", hint and list entry removed
docs/routing-profiles.md	eco SIMPLE chain and free cascade name nano-30b; "all seven"	nano-omni; cascade of six; delisting noted	Prettier re-aligned the ECO table
docs/9-free-ai-models-zero-cost-blockrun.md	table row, "The Fast One" section, /model nano-30b, "Five/Two of the seven", quick-chat pick	removed or updated to six; quick chat → Nano Omni; the volatility section notes the 09-08 delisting; "verified live 2026-08-30" → "checked against the live catalog 2026-09-29"
scripts/reinstall.sh	/model nano-30b line	removed

Left alone on purpose

• docs/clawrouter-vs-openrouter-llm-routing-comparison.md image alt text "92% cost savings". It describes a PNG (clawrouter-cost-transparency-nexus-92-savings.png) that shows 92% in its pixels. An alt text that disagrees with its image is its own bug. The image needs regenerating or removing; that is a design call, not a literal swap.
• Dated or measured posts: docs/anthropic-cost-savings.md (70% title and ~68%/81%/89% rows, "Cost data … March 2026"), docs/smart-llm-router-14-dimension-classifier.md (85% median, dated snapshot post), docs/plans/2026-02-03-* (design plan), CHANGELOG.
• Numbers that are not the product savings claim: compression ratios (7-15%, 15-40%), a model-vs-model comparison (features.md 76%), sample log output (saved 99%), the example x-clawrouter-savings: 82% header, and the 50% subscription example.
• dist/: rebuilt only at release (last touched in v0.12.278). npm run build plus the smoke check pass locally. I did not commit the output.

📝 Walkthrough

Walkthrough

The free-model lineup no longer includes Nemotron 3 Nano 30B. Its aliases now target Nano Omni, and related router references, tests, and documentation reflect the change. Savings claims are updated, and the router-core development dependency points to a new commit.

Merge Risk: 🔵 Low · up to 9aa61

The redirects work as intended, but the new test would miss a later redirect to a different live model. Adding the destination assertion is a bounded follow-up.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 9aa61

Retiring the model does not show a new privilege or payment bypass, but some existing direct pins can now encounter balance checks or a different free model despite retaining a free-model label.

Retained concerns

• Low · architecture · observed: The retained, zero-priced Nano 30B direct pin no longer belongs to the proxy’s free-model set. Unlike its redirected aliases, it can trigger balance or budget controls and can be substituted on insufficient balance; a sticky session can continue to hold the retired ID.

Security review details

Security Blast Radius

• inferred — The affected attacker-selectable input is the request’s model name. Its local consequences are model selection, session pinning, and wallet or budget preflight for that request or session; the available evidence does not establish a broader tenant or privilege change.

Security Findings and Attack Paths

• inferred — No new paid or privileged route is established for the changed aliases in local source: they resolve to Nano Omni before the free-set check. The direct-pin discrepancy is a stricter-control and contract-consistency issue, not a demonstrated way to evade payment controls.

Trust Boundaries and Controls

• observed — The proxy normalizes and resolves caller-supplied names before classifying free models. Non-free classification retains balance and budget gates; an insufficient-balance result substitutes an available free model rather than bypassing those gates.

Resilience and Maintainability Implications

• inferred — Free status is enforced by set membership rather than the catalog’s zero prices. Retaining a zero-priced direct pin outside that set creates policy drift and can repeatedly invoke balance-dependent recovery for a sticky pin.

Hardening Proposals

• proposed — Define one explicit policy for legacy direct pins—redirect them to the live free target before session persistence, or make their different status clear in the catalog—and verify the pinned router revision and gateway redirect before rollout.

108-119: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Assert the Nano Omni target for all five redirected aliases.

The test rejects only free/nemotron-3-nano-30b. It passes if the five aliases resolve to any other live model. Define nanoOmni without the free/ prefix, then assert that each redirected alias resolves to free/${nanoOmni}.

Suggested fix

     expect(aliased).toEqual([]);
+    const nanoOmni = "nemotron-3-nano-omni-30b-a3b-reasoning";
+    const nanoOmniAliases = [
+      "nemotron-nano-9b",
+      "nemotron-nano",
+      "nvidia/nemotron-3-nano-30b",
+      "nano-30b",
+      "nemotron-nano-30b",
+    ] as const;
+    expect(nanoOmniAliases.map((alias) => MODEL_ALIASES[alias])).toEqual(
+      nanoOmniAliases.map(() => `free/${nanoOmni}`),
+    );
