It does not start Codex, open a transport, write a database, or +advance a delivery attempt. + +Native session identity remains on `NativeBinding.native_session_id`. Native +event, item, turn, and thread identifiers are retained in the typed provider +extension when the source exposes them. The extension holds one +`native_event_id`, so the most specific available identifier is kept in this +order: an explicit event ID (`native_event_id`, `event_id`, or `eventId`), a +plain `event.id` on an event without a JSON-RPC `method`, the item ID +(`item.id`, then `params.itemId`), the +turn ID (`params.turn.id`, then `params.turnId`), and the thread ID +(`params.thread.id`, then `params.threadId`). A missing identifier stays +`None`. The `id` of a JSON-RPC request (an event with a `method`) is never an +event ID; it is the attention correlation ID.

They are evidence for a later +control-plane transition, not automatic `DeliveryAttempt` mutations. A +transport receipt is not native completion, and a completed native turn does +not by itself prove that an arbitrary logical message was delivered. + +`native-wire.jsonl` uses the installed interface's camelCase item vocabulary +and `thread/tokenUsage/updated` event shape. The normalizer has explicit +aliases for those item discriminators and keeps the earlier snake_case fixture +spellings compatible. This is a fixture-backed wire-shape check, not a claim +that every installed Codex mode emits the same records. + +`native-thread-status.jsonl`, `foreign-thread.jsonl`, +`native-metadata.jsonl`, and `terminal-unknown-status.jsonl` cover structured +thread state, binding identity isolation, observed model metadata, and +contradictory terminal statuses. Foreign-thread records remain unknown +evidence so the shared projection cannot advance this binding's native state +from another thread. + +Native attention correlates on the request ID. The deduplication key is +`codex-request:<threadId>:<requestId>`, derived from the request `id` and from +`params.requestId` on the resolution, so a re-announced request maps to the +same attention item and a resolution resolves only its own request. The shared +projection rejects a resolution that has no accepted request, and that would +stall the cursor. A caller that tracks accepted requests can pass +`attention_keys` to `observe_codex_event`/`normalize_codex_event`; a resolution +for any other key is then kept as `unknown` evidence. Without it the adapter +is stateless and does not know which requests were accepted. Batch helpers do +not carry this state. + +Duplicate records retain their original cursor and evidence reference. The +shared `ContractStore` handles idempotent ingestion and cursor-gap projection; +the adapter preserves the order supplied by the caller so a reconnect can +replay from a stored cursor without assigning new source positions. + +Malformed envelopes fail before normalization. In particular, missing source +cursors, missing raw evidence references, malformed timestamps, wrong cursor +types, and invalid usage values are not silently repaired. An unknown but +well-formed native event remains a normalized `unknown` event pointing at its +raw evidence. + +A logical-message identifier may appear as `logical_message_id` or +`logicalMessageId` on the envelope, the native event, or its `params`. Null +values are ignored, but any two non-null values that differ, or an empty or +non-string value, raise `CodexAdapterError` before an event is emitted. The +adapter never picks a winner by precedence; only a single agreed identifier is +carried into `NativeEvent.logical_message_id`. + +## Capability evidence + +The following claims are fixture-scoped. They must not be upgraded to `live` +until a separately authorized native proof exercises the actual installed +Codex interface and transport. + +`codex_fixture_capabilities()` returns the same claims as typed shared +`CapabilityResult` values, and `CodexFixtureAdapter.capabilities` exposes them. +Each proved or partial claim carries `scope="fixture"` and an `evidence_ref` +that names an existing sanitized fixture record; unsupported claims carry +`scope="fixture"` and no evidence, and live behavior is a single `unknown` +claim with unverified scope. +The declarations are separate from provider metadata on `NativeEvent`. + +| Capability | Fixture status | Live status | +| -------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------ | +| Preserve native session and event identity | proved by sanitized fixtures | unproved | +| Accept structured native thread status without treating it as turn completion | proved by `native-thread-status.jsonl` | unproved for all live notification variants | +| Isolate events from a foreign native thread | proved by `foreign-thread.jsonl`; foreign activity, delivery, attention, and completion stay unknown | unproved for a live multi-thread stream | +| Preserve source cursor/order and raw evidence references | proved, including gaps and reconnect replay through the shared contract | unproved for a live cursor protocol | +| Preserve observed model/provider/effort metadata | partial: fixture proves `model`, `modelProvider`, and turn `effort` when exposed | unproved for attribution and all live event shapes | +| Distinguish receipt, delivery activity, output, completion, interruption, and quiet evidence | partial: only the listed event shapes are covered | unproved | +| Explicit attention request and resolution | partial: complete generic payloads and the native approval, single-question user-input, and `serverRequest/resolved` shapes above; replay and re-announcement do not duplicate attention | unproved; sending an answer back to Codex is not implemented | +| Usage visibility | partial: input/output counts when exposed | unproved; attribution, limits, and billing remain unknown | +| Context continuation observation | partial: compaction/resume-shaped records only | unproved | +| Reject conflicting logical-message identifiers | proved by `conflicting-logical-message.jsonl`; disagreement across envelope, event, and params is rejected and nothing is ingested | unproved | +| Send an answer to an attention request | unsupported in this adapter | requires a gated live proof | +| Discovery | unsupported in this adapter | requires a gated live proof | +| Session creation | unsupported in this adapter | requires a gated live proof | +| Transport ownership | unsupported in this adapter | requires a gated live proof | +| Steering | unsupported in this adapter | requires a gated live proof | +| Process lifecycle | unsupported in this adapter | requires a gated live proof | +| Live native behavior | not applicable to fixtures | unknown; no Codex process was started | + +The fixture tests therefore establish deterministic normalization and recovery +inputs, not that Codex emits these records in every mode or that a native +session accepts a message.

Live ingestion still requires the current owner + and retains the original stored event on reconnect. Batch replay selects the + earliest ownership generation (then ingestion time) as the canonical observation + regardless of input order.
