Code Review
This pull request syncs DOSRouter with ClawRouter 0.12.297 source. Key changes include the introduction of a dynamic model catalog that periodically refreshes from the upstream gateway, process-local outcome tracking to demote failing models in fallback chains, and strict local HTTP guards to reject non-local or cross-site requests. Additionally, the routing engine has been updated with CJK-aware token estimation, bounded prompt scanning, and a more robust keyword-matching algorithm that handles stems and inflections. There are no review comments to evaluate, so we have no further feedback to provide.

Code Review
This pull request syncs DOSRouter with ClawRouter 0.12.297 source, introducing dynamic model catalog refreshing, local-only client HTTP guards, and a bounded outcome memory to track model reliability and demote failing candidates. It also adds verified tool recovery candidates, CJK-aware token estimation, and inflection-aware keyword matching. Feedback on these changes highlights potential out-of-memory (OOM) vulnerabilities in proxy/proxy.go where upstream response bodies are read entirely into memory; using io.LimitReader is recommended to safely bound memory consumption.

- Line 437: Update the hunyuan, hy3, and tencent alias mappings to resolve
directly to qwen/qwen3.7-flash; do not rely on the deprecated tencent/hy3
entry’s FallbackModel for explicit requests.
Review comments at @proxy/spending.go:
- Line 41: Update the spend-limit guard in the request handling flow to treat a
non-nil FlatPrice with value zero as a zero-cost claim, while preserving the
existing free/ model exception; add a flat: 0 case to
TestRemoteFreeClaimCannotBypassSpendLimits.
Review comments at @router/text.go:
- Around line 28-30: Update the limit clamp in sampleForScan so non-positive
limits use the configured default of 500 rather than 1; preserve the existing
behavior for positive limits.

Final source-review acceptance for 401a1e0:
CodeRabbit completed the full implementation review at ancestor 35a4b8c. Its three findings and both Gemini body-limit findings are fixed with regressions and all five native threads are resolved. Codex/Claude automatic reviews were quota-skipped; CodeRabbit's incremental run was rate-limited, so its SUCCESS status was not used as evidence of delta review.
An independent local reviewer read the complete 13-file delta 35a4b8c..401a1e0 and affected call sites, reporting Ready to merge: Yes, with no actionable Critical, Important or Minor findings. Coverage included per-attempt catalog reasoning, bounded response reads and settlement/cancellation, empty arrays/multiple choices, zero flat-price admission, alias/pin compatibility, scan defaults and the patch-only toolchain update. This is source review, not live-provider or deployment verification.
Final-head local tests/vet/build passed. Linux CI passed go test -race -count=1 ./..., govulncheck (zero reachable vulnerabilities), and Go/Actions CodeQL. The upstream head was rechecked as 78e489ab0c877831672fc317763f391aad5154b1. No deployment or paid provider request was performed.
Synchronize the Go runtime from ClawRouter v0.12.279 to upstream main
78e489a(package 0.12.297). The newest published GitHub release/tag is v0.12.294; subsequent source changes are included explicitly.8773a99, preserving DOS compatibility and free-to-free aliases.The sync tracker classifies exclusions. The existing Go rules strategy remains; optional portfolio task-affinity/speed probes, repetitive-output loop detection, OpenClaw/Desktop/npm surfaces, account reconciliation and Solana settlement are not introduced. Use Go 1.26.10 to clear 10 reachable standard-library advisories found by the existing CI scanner; keep the language minimum and module dependencies unchanged. No deployment, paid provider call, credential change or x402 signing is included. Catalog metadata is source evidence, not live DOS-provider availability.
Validation: all Go tests, vet, build and diff checks pass locally; all 16 tier chains match pinned core after DOS free-ID mapping. New regressions cover catalog isolation/validation/redirects/free billing, fallback outcomes/pins/window expiry/concurrency, local HTTP trust, CJK and scoring. govulncheck passes locally on Go 1.26.10 with zero reachable vulnerabilities (18 module-level advisories are not called). Native Windows lacks cgo, so the existing Linux CI job supplies race verification. Await the configured CI/security/CodeQL checks and completed CodeRabbit source review before merge.
