Summary

  • upgrade the AntSeed CLI to 0.1.153, vendor the compatible @antseed/router-local plugin, and disable runtime plugin updates so fresh pods do not depend on npm
  • persist error_kind, http_status, and AntSeed's stronger lastReachedAt reachability signal in the shared host store, preserving the last known value when a browse omits it
  • add durable, bounded route/peer cooldowns with automatic half-open recovery; request/payment faults do not poison seller health, and model 404s stay route-scoped
  • choose healthy, reachable, reputable sellers before applying offers_top_n, so cheap dead peers can no longer hide a working seller; normal policy price ranking still applies to the admitted candidates
  • preserve direct on-chain dashboard deposits with the CLI's new buyer deposit --onchain <amount> syntax
  • add regression coverage and an offline image-level CI check for the vendored router plugin

Why

AntSeed candidates were truncated to the three cheapest peers before reliability was considered. Failed peers also became optimistic again when the 15-minute statistics window expired, so unavailable sellers were continually recycled while a viable fourth seller could remain invisible.

The current AntSeed CLI also split its default router into a separately installed plugin and changed direct-deposit syntax. Without handling both changes, a new sidecar volume could require a runtime npm install and dashboard deposits could enter the interactive QR/watch flow.

Verification

  • GitHub CI: 773 passed, 2 skipped in the complete Python/Node suite
  • GitHub CI: policy core 637 passed, 0 failed, 0 errors
  • GitHub CI: router and AntSeed images build; all 11 shipped sidecar modules resolve; CLI reports 0.1.153; the vendored local router loads under --network none; router /healthz passes
  • local clean-worktree validation used the exact core submodule SHA referenced by the PR
  • isolated zero-balance P2P canary joined the AntSeed network, listed 335 models, and a peer-pinned free qwen3-235b-instruct request returned HTTP 200 with exactly antseed-ok

Review Change Stack

📝 Walkthrough

Walkthrough

The PR adds explicit AntSeed wallet CLI argument handling, vendors a pinned router plugin in the Docker image, and adds durable route and peer health tracking. Marketplace offers now use cooldown, reachability, reputation, and health data during admission and ranking.

Changes

Wallet CLI and image packaging

Layer / File(s) Summary
Wallet CLI argument contract
antseed/cli-args.js, antseed/control.js, antseed/cli-args.test.js, tests/test_antseed_node.py, antseed/broadcast.js
Wallet deposits use buyer deposit --onchain <amount>. Withdrawals keep positional arguments. Unsupported verbs raise an error.
Vendored router image validation
Dockerfile.antseed, .github/workflows/ci.yml
The image pins AntSeed CLI 0.1.153, vendors @antseed/router-local@0.1.45, disables runtime plugin update checks, and validates router loading in CI.

Marketplace health admission

Layer / File(s) Summary
Health and reachability persistence
host_store.py, antseed/write-market.js, llm_router_host.py, tests/conftest.py, tests/test_host_store.py
Route observations persist error metadata. Peer offers persist last_reached_at. Marketplace reads, writes, fixtures, and assertions include the new fields.
Durable route and peer health
host_store.py, tests/conftest.py, tests/test_host_store.py
Recent observations produce route and peer health data. Consecutive attributable failures are tracked. Neutral client faults are ignored.
Health-aware offer admission and ranking
sources/antseed.py, providers.py, tests/test_antseed_offers.py
Offers use cooldowns, half-open recovery, reachability freshness, reputation, and health-first ranking. Source statistics expose cooling, half-open, and stale-reachability counts.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 3f1d6

The PR improves seller recovery and removes runtime npm dependence, but an incomplete reachability update could temporarily misclassify a seller, while the plugin check and dependency installation may not fully prove offline or reproducible builds. The change is mergeable with explicit owner awareness and follow-up on these bounded risks.

19-26: 🔒 Security & Privacy | 🔵 Trivial | ⚡ Quick win

Lock the complete plugin dependency tree.

--save-exact pins the direct plugin version, but this build creates package-lock.json only inside the temporary build stage. Later builds can resolve different transitive versions. Commit a dedicated plugin manifest and lockfile, then use npm ci --ignore-scripts for this installation. npm documents that lockfiles record the exact dependency tree and that npm ci installs it without updating the lockfile.

- Around line 67-76: Update the peer-offer upsert’s last_reached_at assignment
in UPSERT to retain the existing database value when the incoming
peer.lastReachedAt is null, while still replacing it for non-null values. Apply
the same behavior to the equivalent test-fixture upsert and add a regression
test covering an incomplete browse payload preserving the previously stored
timestamp.
