Summary
Retain opaque provider state for compatible replay and persist/replay plain-text reasoning across models. Readable reasoning is also exported through OTLP; encrypted state and signatures are not.
LLMResponse.reasoningWhy this layer exists
A provider response has public conversational meaning and sometimes private protocol state. Anthropic returns signed thinking blocks; Gemini returns thought signatures, including signatures embedded by LiteLLM in tool-call IDs. Those artifacts may be required for the next compatible request, but they are not ordinary prompt text and must never reach another provider.
NOOA therefore needs two representations at two different boundaries:
LLMResponseused by events, SQLite sessions, formatters, middleware, and strategies;The event record stores readable reasoning as text and the provider artifact as one opaque
llm_stateblob. It does not grow Anthropic/Gemini fields. The replay adapter opens that blob only after the target scope and the unchanged public assistant carrier prove that it belongs.This also protects cache stability. Reconstructing the original provider message at the edge preserves the provider's expected turn shape; the public event history remains canonical and does not accumulate synthetic or partially translated provider messages.
Code walkthrough: what changed and why
Anthropic capture and replay.
What: CompletionClient captures native thinking and redacted-thinking blocks, including signatures, and restores them only on a matching Anthropic Chat scope and unchanged carrier.
Why: signed thinking must remain paired with the exact turn that produced it and is unsafe outside that compatibility boundary.
Gemini capture and replay.
What: UnifiedLLM captures message-level and per-tool thought signatures. When provider evidence identifies LiteLLM's inline signature suffix, NOOA exposes a clean public tool-call ID, stores the suffix privately, and restores the private ID on both the assistant tool call and its later tool-result message.
Why: Gemini requires matching signed call/result IDs, while NOOA tools, event storage, and other providers need stable public IDs with no opaque payload embedded in them. A non-Gemini ID merely containing
__thought__remains an ordinary ID, even with an empty suffix.Shared full-carrier proof.
What: feat(llm): retain compatibility-scoped OpenAI reasoning state #310's exact carrier binding is generalized across supported Chat state: assistant text plus each ordered tool call's ID, name, and arguments must still match.
Why: checking only IDs or list length could attach stale signatures after middleware changes the actual request.
Plain-text reasoning: persistence, cross-model replay, and OTLP export.
What: Chat reasoning and OpenAI Responses summaries populate
LLMResponse.reasoning. When opaque replay is unavailable, refactor(llm): make LLMResponse the canonical assistant turn #312's provider-independent path demotes that text to ordinary assistant context. The tracing adapter emits Chat reasoning and native Responses summaries asllm.reasoning_content, including when journal mode strips the full LLM message attributes.Why: readable reasoning can remain useful after model/provider switching without teaching the target a foreign private schema. A valid summary without encrypted content is ordinary text, not a corrupt response; mixed summary-only/encrypted sequences demote together instead of partially losing reasoning. OTLP is observational, not a replay archive, so human-readable reasoning must remain available without exporting opaque protocol state.
Direct wire-state stripping.
What: raw thinking blocks, provider-specific fields, and confirmed inline signatures supplied directly in public messages are removed and reported. Only a validated NOOA envelope can restore them.
Why: otherwise callers, old middleware, or archives could bypass the compatibility gate.
Visible failure policy.
What: expected model/API incompatibility or a changed carrier warns and safely demotes text. Malformed current envelopes, unsupported known-provider shapes, ambiguous tool identity, unsupported Responses items/content blocks, invalid stored ordering, and unscopable opaque output raise
ReasoningReplayErrorrather than retaining a partial turn; strategies do not retry that deterministic error.Why: model switching is recoverable. Corrupt state or a newly changed provider contract is a framework defect and must not be silently swallowed.
Trace privacy.
What: scrubbers cover OpenAI encrypted content, Anthropic signature/data fields, Gemini snake/camel-case signatures, JSON-string attributes, and flattened inline IDs.
Why: excluding blobs from
repris insufficient if HTTP or tracing diagnostics can export them.No provider leakage into the event system.
What: provider details remain concentrated in
unifiedllm/replay_state.py; storage and rendering continue to depend only on canonicalLLMResponse.Why: NOOA should expose one durable turn interface, not LiteLLM objects or a catalog of provider message classes.
Keep result IDs and turn bookkeeping consistent.
What: structurally confirmed inline-signature removal also updates the matching tool result; an aborted CodeAct replay emits a final failed turn. HTTP logging reuses the shared tracing scrubber.
Why: a cleaned assistant ID must still match its result, failed generations must not look resumable, and one redaction implementation prevents provider handling from drifting between logs and traces.
Supported surface
Native Bedrock and Vertex opaque replay remain fail-closed until their issuer compatibility is established. NVIDIA's OpenAI-compatible routes work when the response itself carries the supported Anthropic/Gemini structure; no model-name condition is used.

Validation
OTLP/copy-reduction round (2026-09-11): 724 passed across tracing and UnifiedLLM; eight OTLP cases exercise real span finalization, secret scrubbing, journal-mode filtering, and HTTP JSON serialization for Chat reasoning fields,
<think>text, and native Responses summaries. No inference calls. Ruff and targeted Pyright pass.latest regression round: real SDK → JSON/SQLite → serialized HTTP tests cover multi-block text, ordered/phased messages, summary-only reasoning, unsupported whole-turn rejection, and eligible Anthropic cache-marker fallback; independent repeat review found no remaining blockers
focused replay/formatter/tracing/strategy set after review: 152 passed
final combined stack: 7,364 passed, 10 skipped, 239 deselected, 3 expected xfails
mutations of text, tool name, arguments, IDs, order, count, state-only carriers, and direct thinking fields withhold opaque state
Ruff, targeted Pyright, DCO trailers, and diff checks pass
top-stack live NVIDIA Inference Hub SQLite close/reopen tests: Sonnet 5 and Gemini 3.1 Pro retained exact opaque state and stable wire requests; resumed calls reported 10,847 and 24,491 cached input tokens respectively. Sonnet 5 used the hub's native Anthropic Messages endpoint.
