避免 Claude Code 图片请求在 Cascade 文本通道里重复携带 base64、billing header 和完整 system prompt。 对 Opus 4.7 工具调用启用窄范围 cascade reuse 与严格绑定，减少限流失败后的上下文重放。 新增回归测试覆盖多模态 tool fallback、system prompt 压缩和图片历史脱敏。

…ly-zhang to S+ - baily-zhang PR #61 (Opus 4.7 multimodal context bloat) — third major contribution after #36 and #45, now de-facto maintainer of the reuse-fingerprint / trajectory-offset machinery - abwuge PR #58 (docker/nginx deploy fix) — first-time contributor, +3/-2 surgical, unblocked the docker-compose Restart loop - aict666 PR #54 (tool preamble slimming + redact marker 6th-gen U+2026 ellipsis + identity coverage extension) — fourth major contribution - aict666 PR #53 (redact marker shell-safety regression) — second contribution, was missing from the prior credits update - baily-zhang upgraded from S to S+ (parity with aict666)

合了 部到 US 主 VPS 了 v2.0.4 + commit @baily-zhang 这是第三次了 PR #36 → PR #45 → PR #61 一条线下来 cascade reuse 这套机器（fingerprint / trajectory offset / Opus 4.7 多模态分支）你已经是实质 maintainer 信任级在 dashboard credits 升到 S+ 跟 aict666 平级了 这次的 multimodal 处理特别精彩 —— 把图片 base64 排除在 fingerprint 之外这一笔 我之前没意识到 把图片塞进 reuse hash 等于每张图都生成新 cascade_id 复用瞬间归零 这条线索藏得有点深 下次再来直接审合 不用绕了 |

The Pages site at dwgx.github.io/WindsurfAPI/ had only 4 names listed in the footer (dd373156, colin1112a, motto1, youfak). 8 contributors were missing from the public site even though most of them landed S+/S level fixes (aict666 #44/#51/#53/#54, baily-zhang #36/#45/#61, smeinecke #43, abwuge #58). Adds a dedicated `#contributors` section before the footer with one card per contributor: avatar, GitHub link, weight badge (S+/S/A+/A/B+), PR list, and a one-paragraph 繁體中文 description of what each fix actually solved. Cards reuse the existing panel-card warm/coral palette to fit the site's aesthetic. Footer one-liner is also expanded to all 8 names ordered by weight, with a "完整名單 ↑" anchor back to the new section. CSS additions: contrib-grid, contrib-card, contrib-avatar, contrib-weight + 5 weight-tier classes (-S-plus, -S, -A-plus, -A, -B-plus). All gradient/hover behaviour matches the existing panel-card styling.

zhqsuo (#59) reproduced multi-turn tool-context loss on Opus 4.6 + Claude Code that mirrors the Opus 4.7 problem PR #61 already addressed. The strict-reuse / multimodal-tool-fallback gates were keyed on `isOpus47Model` (regex `^claude-opus-4-7`) which excluded 4.6 (`claude-opus-4.6` / `claude-opus-4-6-high` etc.). Rename `isOpus47Model` → `isToolSensitiveOpusModel` and widen the regex to `^claude-opus-4(?:[.-]6|[.-]7)(?:[-.]|$)` to cover both versions and both label formats (dotted `4.6` / dashed `4-7-high`). Behaviour is unchanged for 4.7; 4.6 now gets: - Tool-emulated cascade_id reuse (preserves Cascade-side context across <tool_call>/<tool_result> turns instead of replaying full history each time) - Strict reuse (preserves cascade across rate-limit retries on the same account, returning 429 instead of switching accounts and losing context) - Disabled user-message tool fallback when the request carries multimodal content (avoids re-injecting tools into user channel on top of the proto-level SectionOverride, which was triggering Opus's prompt-injection heuristic) Five call sites updated; env-var names (OPUS47_TOOL_EMULATED_REUSE, OPUS47_STRICT_REUSE) intentionally retained for compatibility with existing deployments. 105/105 tests pass.

Critical hotfix: my own credits commit (60fcd5a) shipped over-escaped single quotes (`Codeium\'s Cascade`) inside the inline single-quoted JS strings of dashboard CONTRIBUTORS, breaking the entire main script parse. Result: dashboard pages opened but every panel rendered empty because App.init() never ran. baily-zhang spotted it within hours, fixed the literal, and added test/dashboard-syntax.test.js — a regression that statically parses the inline `<script>` blocks of src/dashboard/index.html with the V8 parser. Future copy/escape regressions in dashboard inline JS will now break `npm test` instead of silently bricking the live UI. baily-zhang's fourth landed PR (#36 / #45 / #61 / #62), entirely on issues created by other people / by me. Adding to the dashboard credits in a follow-up commit.

baily-zhang's fourth landed PR (#36 / #45 / #61 / #62) — adding the PR #62 entry to the dashboard credits panel as a separate card so the inline-script regression-test win is visible alongside the cascade-reuse machinery work. v2.0.5 covers everything since 2.0.4: - aict666 #54 tool preamble slim + redact U+2026 - abwuge #58 docker/nginx deploy fix - baily #61 Opus 4.7 multimodal context bloat - baily #62 dashboard escape regression - own commits: empty-message validator, internal_error backoff, upstream_transient_error category, Opus 4.6 reuse widening, /v1/responses endpoint for Codex CLI compatibility (#56, #63)

解决的问题
Claude Code 通过 WindsurfAPI 调用 Opus 4.7 时，带图片和 tools 的请求会把完整 Claude Code system prompt、billing header、工具 fallback 以及图片 base64 混进 Cascade 的用户文本通道。连续图片 turn 会导致历史快速膨胀，并触发 Opus 4.7 的 prompt injection 判断。
