Code review — PR #344 (docs drift: slippage tolerance validation)

• Read changed files in full context
• Check conformance to CLAUDE.md style rules
• Verify cross-references / links resolve
• Check for internal-only leakage
• Post review feedback

This is a tight, well-formed drift PR. It correctly applies the breaking-change playbook (§4.2): the surface page (handling-errors.mdx) is edited in place, the narrative lives in the changelog, and there's no redundant inline <Warning>. Both changes are accurate against the described behavior and self-consistent (the errorCode string matches between the two files).

Verdict: approve / ready to mark for review. No blocking issues. Two minor style observations below — both optional.

---

What's correct ✅

• Changelog format (§4.5): newest-first ordering is right (2026-06-23 sits above 2026-06-10); ## date heading + one-line summary; **Breaking** lead on its own line. Date matches today (absolute, per the convention).
• Link resolves: [Handling Quote Errors](/references/api/api_core_concepts/handling-errors) is root-relative and points at the real file. ✓
• Backtick usage (§2.9): code values (slippageTolerance, latePaymentSlippageTolerance, 0, 10000, the error code) are correctly backticked in prose; the table Property-style values follow suit.
• No internal leakage: "produced refund outcomes downstream" / "removing the minimum-output floor" are behavioral descriptions — no service names, file paths, or internal components. ✓
• No companion pages missed: I grepped the other 7 files mentioning slippageTolerance. They reference it only as a response object (price-stabilization, etc.) or in unrelated contexts — none document the input validation range, so nothing else needs updating.

Minor observations (optional, non-blocking)

1. Changelog paragraph length (§2.10). The **Breaking** body is a single 5-sentence paragraph. §2.10 caps paragraphs at 2–3 sentences. That said, the existing entries (e.g. 2026-05-21 Hyperliquid, 2026-06-10 reorg) are comparably dense, so this is consistent with established practice in the file. If you want it to read tighter, the "Previously…" history (sentence 3) and the POST /price 500→400 note (sentence 4) could split into a second paragraph — purely cosmetic.

2. Error-table cell length (§2.7). The new INVALID_SLIPPAGE_TOLERANCE description is noticeably longer than its neighbors, which §2.7 nudges away from ("keep cell descriptions concise"). It's still a single sentence and the range is the useful bit, so I'd leave it — just flagging the asymmetry.

One thing worth a human glance (not a docs issue): the changelog scopes the change to POST /quote, POST /quote/v2, and POST /price, but the handling-errors.mdx page is framed entirely around /quote/v2 ("When calling the /quote/v2 endpoint…"). The cross-link still works since the error code is documented there, but if /price callers are expected to land on this page, that's the page's existing scope limitation rather than anything this PR introduced.
