fix(claude): publish an input estimate the settled route actually sends - #5942
moseoridev wants to merge 4 commits into
Conversation
`message_start.usage.input_tokens` comes from a char-based estimate of the caller's body whenever the upstream has not reported usage yet. Claude Code replays its own thinking blocks, and on a long session those dominate the body: on a captured 260-message turn they were 78.8% of the messages JSON, 56.7% of that being base64 signatures. A routed OpenAI Chat wire serializes almost none of it. The signature never reaches the wire at all, and the text is dropped unless the model is on the provider's `preserveReasoningContentModels` list. Counting the caller's own blocks therefore measured something the proxy does not send, and the published floor landed 3.28x above the count the upstream reported - well past the >2x drift bound the estimator is held to (devlog 260711_claude_inbound 040 §3). Paseo's context meter reads that frame, so it showed 221% of a 180k window while compaction was healthy. Project the ESTIMATE onto the settled route instead: drop exactly the replayed thinking fields the settled adapter will not serialize. The caller's body is never rewritten. `openAIChatSerializesThinking` becomes the single source of truth for that question, shared by the adapter that decides `reasoning_content` and the estimator that prices it, so the two cannot drift. `count_tokens` resolves its route through the read-only `previewRouteModel` so a count cannot advance combo round-robin state. The Anthropic-native wire is unchanged: nothing is projected away there, and an unknown route keeps the estimator's long-standing behavior. Verified against the real upstream on the captured body that produced the defect: message_start 432068 -> 104318, delta 131907 (ratio 3.28x -> 0.79x).
The Messages ingress published a floor 3.28x the prompt the upstream billed, because the estimator priced the caller's body while the openai-chat lane drops replayed thinking entirely. Records the measurement, the projection, and the live before/after. Refs lidge-jun#4857.

…cted thinking Three CodeRabbit findings on the route-aware estimate, all confirmed against the code and each pinned by a regression that fails without the fix. `redacted_thinking` is its own axis. The projection carried only `text` and `signature`, so an opaque `redacted_thinking.data` blob — which no Chat wire has a field for — stayed in the measured JSON and inflated the floor. It is now a third field on `ClaudeThinkingProjection`, false for every Chat route, and the identity fast path requires all three. The floor memo was first-write-wins. The pre-dispatch callers and the post- dispatch translator can legitimately want different wires — a combo re-picks its child at dispatch, a retry can rotate the adapter — so the first measurement could outlive the wire it described. The memo is now keyed on the projection, and `thinkingProjectionForDispatch` reads `logCtx.activeAttempt` once a send exists, falling back to the ingress route only until then. A Chat identity is re-derived through `routedProviderConfig`: `preserveReasoningContentModels` is registry- merged, so reading the raw config row priced a preserve-listed model as if the wire dropped its reasoning. `count_tokens` skipped the wire settlement the turn path performs, so a `modelAdapters` override priced the count against a body the routed adapter never sends. It now settles static policy and the wire override in both directions. Regression: nine cases in tests/claude-integration/claude-estimate-projection.test.ts. All five new ones fail on the parent commit, and the registry-merge case fails with only the `routedProviderConfig` line removed (34 vs 1943).

A combo target may name its model by alias, and `routeConcreteModel` is where that becomes the provider's native id — the same value `applyFinalRouteRequestNormalization` writes to `parsed.modelId` before any adapter reads a per-model list. The attempt row kept the alias instead, so `openAIChatSerializesThinking` consulted `preserveReasoningContentModels` under a name that is not in it (matching is exact) and priced replayed thinking as dropped for a wire that serialized it. The floor then published 34 where the body it described was worth ~13,600, the mirror of the over-count this PR fixes: an understatement of a real prompt, which is the direction that costs a context meter its safety margin. Every other attempt writer already records `route.modelId`; the combo child was the outlier. Verified: the new case publishes 34 with the alias in the attempt row and passes once it carries the resolved id, while the wire itself always sent the native id.

The Claude source PR already records `targetRoute.modelId` and includes the combo-alias regression; reverting that line makes the alias case fail. Review follow-up: the DeepSeek V4 Flash DSH/ZCode export expectations now match all five calibrated efforts. Devin combo children now bypass the optional stated-reset wait and surface their pre-output refusal, so the combo can advance promptly; standalone opted-in turns retain reset waiting and heartbeats. The delayed-reset combo and real Devin adapter regressions were red before the fix and green after it. The alternate Antigravity 403 PR (#5976) was left out because the included implementation covers the same retry with more extensive tests for bearer/project identity, cancellation failure, retry bounds, redirects, and fallback. No code was taken from that alternative.

Defect
message_startpublishesestimateClaudeRequestTokensas the floor for the prompt this proxy forwarded. The estimator measured the body the caller sent, which is the same body only on the Anthropic wire. Everywhere else the gap is whatever the target adapter drops, and on a long Claude Code conversation that gap is enormous.Measured on the live path, one real conversation replayed byte-identical (260 messages, 23 tools, 1,734,433 B) at

>2xdrift (devlog/_fin/260711_claude_inbound/040_phase4_hardening.md§3); this is outside it. A Paseo agent reading that floor at a 180k window drew its meter at 221%, which reads as a broken compaction loop. Compaction was healthy — the number above it was not.Why
Claude Code replays its own thinking blocks and they dominate a long body: in the capture, 80 blocks / 550,930 thinking chars / 750,284
signaturechars, with thinking JSON at 78.8% of all message JSON andsignatureat 56.7% of the thinking JSON.The
openai-chatwire forwards that text only for models inpreserveReasoningContentModels, and has nosignaturefield at all (zerosignaturereferences anywhere undersrc/adapters/openai-chat*).thehivedeclares no reasoning policy keys, so it drops both — and upstreams do not bill replayed reasoning they never receive.Not a calibration bug: CJK is 0.07% of the body, and 4 → 3.5 chars/token is ±14% against a 228% error. The
thehive/alias prefix is orthogonal (and dropping it alone makes the number 14% worse).Change
