Previously, isMeaningfulToolCall and hasMeaningfulResponsesCallItem accepted these ID-only scaffolds as meaningful content (setting acc.hasToolCalls = true). In readStreamBootstrap (sdk/cliproxy/auth/conductor_stream.go), when an upstream chunk carries an error but bootstrap.hasMeaningfulOutput() is true, the error is suppressed, appended to the buffer, and readStreamBootstrap returns nil error. executeStreamWithModelPool then sees bootstrapErr == nil and assumes the stream started successfully, permanently disabling failover for that request and delivering an unusable partial tool call to the client. Fix the defect at sdk/cliproxy/auth/empty_completion.go:274-276 by removing the call.ID check in isMeaningfulToolCall, and at sdk/cliproxy/auth/empty_completion.go:776-783 by dropping the item.ID and item.CallID disjuncts in hasMeaningfulResponsesCallItem. This ensures that tool call deltas require a name, arguments, input, or result before being marked meaningful. This aligns with the Claude branch in the same file (sdk/cliproxy/auth/empty_completion.go:822), which already requires both ID and Name (strings.TrimSpace(b.ID) != "" && strings.TrimSpace(b.Name) != "").

fix(translator): preserve strict thought predicate and signature binding Do not classify non-thought parts carrying thoughtSignature as thinking to prevent swallowing visible text. Bind thinkingSignature strictly to parts where thought: true is set so functionCall signatures do not overwrite thinking signatures. Guard flushThinking to avoid emitting phantom empty thinking blocks on functionCall carriers. Handle signature-only finish chunks in streaming path without opening empty text blocks. Add regression tests for carrier text parts, functionCall carriers, signature precedence, and streaming parity.

07:02:56 +0300 Subject: [PATCH 018/149] fix(auth): floor quota cooldown at the escalating ladder Providers answering 429 for an exhausted daily quota can attach a RetryInfo hint far shorter than the real recovery window. Gemini and Antigravity were observed returning 479417207ns while the key stayed dead for the rest of the day. Both quota paths took that hint verbatim, so an exhausted credential returned to the pool half a second later and BackoffLevel never advanced past its current step: every retry recomputed the same level and immediately overwrote the deadline with the sub-second hint. Compute the escalating ladder first and let a provider hint only push the deadline further out, never pull it in. A genuine long hint still wins; a sub-second one can no longer undercut the ladder.

Streaming failures built their results from retryAfterFromError alone, and the Antigravity token-count path built statusErr by hand, so both still floored a provider-classified short-lived 429 at the quota ladder and parked a usable credential. Set TransientRateLimit next to every RetryAfter assignment in the streaming pool, and build the token-count errors through newAntigravityStatusErr so they inherit the same classification. ---

Claude, Gemini, Codex, xAI, and Vertex API-key configs fell through to applyAPIKeyModelAlias and used only the first resolved model, losing sibling-model failover and cache-warm opportunities. Resolve the API-key alias pool for every provider whose config carries Models [] by reusing resolveModelAliasPoolFromConfigModels and the existing nextModelPoolOffset / rotateStrings machinery. Keep the OpenAI-compat pool key behavior; add an apiKeyModelPoolKey for other providers so rotation is per-auth and per-alias. filterExecutionModels continues to drop currently-blocked pool members.

The empty-completion detector had no Interactions branch, so every Interactions stream fell through to unknown data and was committed as a valid response. Port the event set, chunk shapes, evalInteractions, and the finish handling from the upstream review on router-for-me/CLIProxyAPI#4881 (commit baf43ba5). A bare finish with zero output tokens is now treated as an empty completion; one with positive tokens is not.

ClaudeThinkingReplayConversationSessionKey no longer hashes tools, so changing or reordering the tools list between turns does not churn the conversation-scoped replay key. - Identity headers (User-Agent, X-App, X-Codex-Client-Id) are now read case-insensitively to avoid missing lowercase SDK-supplied header keys. - kimiThinkingReplayContentIsReplayable caches signed thinking responses even when they do not contain a tool_use block, and kimiNonThinkingContentParts returns a true validity flag (not hasToolUse) so non-tool assistant turns can be restored. - applyCloaking-sensitive-word obfuscation is now applied to cached replay contents before the post-sanitizer restore, so the replay match compares like-for-like obfuscated bytes and restores trusted signatures after sensitive words are masked.

A Claude tool_result with structured content blocks that themselves carry cache_control would still forward the Anthropic-only field to Kimi and cause rejection. - Make stripCacheControls only target protocol-level cache_control markers on system/tool/message blocks and nested content arrays (e.g. tool_result content). It leaves arbitrary JSON like tool input_schema properties and tool_use input named "cache_control" untouched. - Add stripContentCacheControls to recurse into nested content arrays without wandering into sibling objects such as tool input_schema or tool_use input. - Add TestStripCacheControls and TestStripCacheControls_NestedToolResultContent.

Evicted alias keys are deleted from KV alongside the index. - Store each replay alias as a multi-session list instead of a single mapping so two sessionless conversations that share a visible message do not overwrite each other. - Tag each alias entry with the conversation's first user hash and score alias resolution by message role weight plus a first-user-match bonus. This keeps shared tool_result/user messages from resolving the wrong conversation. - Add internal/cache tests for alias scoring, expiry, home multi-session resolve, and per-credential cap. --- .../cache/claude_thinking_replay_cache.go | 390 +++++++++++++++--- .../claude_thinking_replay_cache_test.go | 231 ++++++++--- .../executor/claude_thinking_replay.go | 63 ++- .../runtime/executor/kimi_thinking_replay.go | 1 + 4 files changed, 554 insertions(+), 131 deletions(-) diff --git a/internal/cache/claude_thinking_replay_cache.go b/internal/cache/claude_thinking_replay_cache.go index cbaaa5922..a64f4913f 100644 --- a/internal/cache/claude_thinking_replay_cache.go +++ b/internal/cache/claude_thinking_replay_cache.go @@ -42,6 +42,16 @@ const ( // aliases kept in the local fallback map.

This prevents a compacted request with only a shared message from restoring the wrong conversation's hidden thinking. - Anchor replay restore to the latest cached suffix that matches the request's full assistant sequence, so duplicate assistant turns resolve to the correct retained signature after truncation or compaction. - Add regression tests for atomic alias list updates, tie rejection, and duplicate-turn suffix anchoring. --- .../cache/claude_thinking_replay_cache.go | 147 ++++++++++-------- .../claude_thinking_replay_cache_test.go | 133 +++++++++++++++- .../executor/claude_thinking_replay.go | 135 ++++++++++------ .../executor/claude_thinking_replay_test.go | 37 +++++ 4 files changed, 340 insertions(+), 112 deletions(-) diff --git a/internal/cache/claude_thinking_replay_cache.go b/internal/cache/claude_thinking_replay_cache.go index a64f4913f..9a8a7a3c9 100644 --- a/internal/cache/claude_thinking_replay_cache.go +++ b/internal/cache/claude_thinking_replay_cache.go @@ -415,12 +415,8 @@ func claudeThinkingReplayUpsertAliasLocked(key, sessionKey, firstUserHash string } func claudeThinkingReplayResolveBestAliasLocked(modelFamily string, messages []ClaudeThinkingReplayAliasMessage, requestFirstUserHash string, now time.Time) (string, bool) { - type candidate struct { - score int - latest time.Time - } const firstUserMatchBonus = 2 - scores := make(map[string]candidate) + scores := make(map[string]int) for _, m := range messages { key := claudeThinkingReplayAliasKey(modelFamily, m.Hash) list, ok := claudeThinkingReplayAliases[key] @@ -431,26 +427,44 @@ func claudeThinkingReplayResolveBestAliasLocked(modelFamily string, messages []C if now.Sub(entry.timestamp) > ClaudeThinkingReplayCacheTTL { continue } - c := scores[entry.sessionKey] - c.score += m.Weight + scores[entry.sessionKey] += m.Weight if requestFirstUserHash != "" && entry.firstUserHash == requestFirstUserHash { - c.score += firstUserMatchBonus + scores[entry.sessionKey] += firstUserMatchBonus } - if entry.timestamp.After(c.latest) { - c.latest = entry.timestamp - } - scores[entry.sessionKey] = c } } - var best string - var bestCand candidate - for session, c := range scores { - if c.score > bestCand.score || (c.score == bestCand.score && c.latest.After(bestCand.latest)) { + return claudeThinkingReplayResolveBestAlias(scores) +} + +// claudeThinkingReplayResolveBestAlias returns the session with the highest +// score.

Aug 2026 08:13:02 +0300 Subject: [PATCH 124/149] fix(cache,executor): avoid reserving Home KV tombstones for no-nonce replay No-nonce fallback scopes are content-derived and unbounded; avoid reserving a Home KV tombstone until a replayable response is actually cached. - Add GetClaudeThinkingReplayWithSnapshotIfExists to read replay state without creating a KV tombstone. - prepareClaudeThinkingReplayRequest uses the non-reserving reader for fallback scopes and the standard reader for nonce-based scopes. - Add test verifying the non-reserving reader does not KVSet for

Added `TestReplaceAliasesIfUnchanged_KeepsRequestedAliases`.
