Native history and tools remain authoritative; do not carry prompt reconstruction into the adapter. | +| Other SDK entrypoints | `backend/src/mainloop/claude_agent.py` contains a direct SDK wrapper. `services/claude_agent.py` calls the HTTP worker and parses text/result/error stream records. `claude-agent/server.py` exposes `/execute` (including a resume session ID and compaction observations) and `/execute/stream`. | Replace deliberately after native proof. HTTP transport errors do not establish that a native prompt was not delivered. These existing entrypoints are unchanged. | +| One-shot job execution | `services/k8s_jobs.py` creates session jobs with prompt/model/callback environment values. `claude-agent/job_runner.py` calls SDK `query`, collects output, native session ID and cost, then posts a result with bounded callback retries. | A stable workspace and native binding must outlive individual process/job identities. Native session IDs must not be confused with product session IDs. No new scheduler or terminal manager belongs in this contract. | +| Durable workflow | `workflows/session_worker.py` provisions a namespace, builds conversation prompts, starts jobs, waits on DBOS result and user-message topics, and updates product session status. Result timeouts currently raise and lead to failure handling. `workflows/main_thread.py` manages user-thread/queue coordination. `workflows/dbos_config.py` configures DBOS queues and replay versioning. | Reuse appropriate durability and routing boundaries later, with explicit delivery uncertainty and fenced ownership. Changing workflow behavior would require a version bump; this slice changes none. | +| Persistence | `db/postgres.py` stores threads, conversations, messages, projects, sessions, queue items and notifications. `workflows/transactions.py` supplies DBOS transaction helpers. `models/session.py` combines product execution and attention-related statuses; `models/workflow.py` carries queue and workflow records. | Add durable bindings, logical messages, attempts, raw-evidence cursors and projections later. Do not treat existing session status or a stored transcript message as a native delivery receipt. | +| Message submission and callbacks | `api.py` `/sessions/{id}/message` saves a user message, then wakes a waiting worker via DBOS. `/internal/sessions/{id}/complete` forwards a job result to the workflow. | Stable logical-message IDs and attempt identities must span submission, delivery and reconciliation. Callback receipt is distinct from native completion evidence. | +| Compaction | `services/compaction.py` invokes SDK summarization and stores derived conversation summaries. `chat_handler.py` and `claude-agent/server.py` also observe SDK `compact_boundary` events. | Keep product summaries separate from native context management. The runtime reports continuation/compaction observations; it does not implement native compaction. Deterministic checkpoints require no summarizer. | +| SSE | `backend/src/mainloop/sse.py` has an in-process per-user event bus with random notification IDs and heartbeat events. `api.py` exposes `/events`. There is no persisted source-cursor replay in this bus. | Reuse notification transport later, backed by durable projections and explicit replay semantics. Browser reconnect alone cannot guarantee missing events are recovered. | +| Frontend | `frontend/src/lib/api.ts`, `sse.ts`, and stores for sessions, session messages, inbox and notifications consume current HTTP/SSE records. `docs/specs/chat.md` and `sessions.md` describe current behavior. | Keep attention, delivery, activity, workspace health and publication distinct in later UI changes. This foundation changes neither HTTP/SSE shapes nor frontend behavior. | + +## Implemented local contract + +`models/src/models/native_agent.py` owns shared Pydantic records. Runtime code +imports these records rather than redefining durable backend models. +`backend/src/mainloop/runtime/contracts.py` implements a single-binding, +single-process reference store; `projection.py` rebuilds a checkpoint from +serialized events and delivery-attempt snapshots. Neither module imports an SDK, +DBOS, application configuration, database client or transport. + +- External dictionaries are validated on entry. Unknown fields, malformed dates, + naive timestamps, invalid event variants and non-integer cursors/generations + are rejected. Records are frozen and collection fields are tuples. +- A logical ID names one immutable message envelope, including authority and + payload references. A duplicate identical request returns the existing record; + changing content under that ID is a conflict. References must identify immutable + content in a future persistence layer; this store does not dereference them. +- Attempts are separately identified and correlated to a recorded message. One + unresolved or successful attempt prevents another send attempt. A retry is + explicit and gets a new attempt ID only after proven non-delivery or failure + before entering `sending`. Attempt identity retries return current state. +- Delivery follows `recorded -> queued -> sending -> delivered -> completed`. + Failure is allowed before sending. Persisting `sending` must precede transport + activity in a future implementation. Disconnect during sending becomes + `uncertain`; timeouts cannot turn it into failure or trigger a replay. + An acknowledged delivery remains delivered across transport loss. +- Resolving uncertainty requires typed evidence tied to the attempt and binding, + with a non-regressing observation time. `not_delivered` allows an explicit new + attempt; `delivered` and `completed` prohibit replay. Evidence references are + assertions supplied by an adapter, not independently authenticated proof here. +- Every store mutation and checkpoint read checks the current ownership + generation. Takeover is a compare-and-swap increment and conservatively marks + in-flight `sending` attempts uncertain. Current owners reconcile historical + uncertain attempts without rewriting their original generation. Production + generation allocation, authorization and durable fencing remain future work. +- Source cursors are positive, contiguous integer positions starting at one, + scoped to a binding and never reset by ownership changes. Adapters must map + their source order to this contract and preserve raw evidence references; they + must not assign a fresh cursor on replay. Opaque provider tokens belong in + adapter-side source mapping, not guessed numeric ordering. + Ownership generations fence ingestion, not source-event order: a new owner can + fill an earlier cursor gap before an event observed by a previous owner. + Projection permits decreasing observation generations across source cursors, + while still rejecting another binding or a future ownership generation. +- The same cursor and semantic payload is one event even if ingestion time or + ownership generation differs. 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. Reusing a cursor for different evidence is a conflict. + Out-of-order events are retained, but projection stops at the first missing + cursor. Filling a gap replays the contiguous prefix in source order. Unknown + events retain raw evidence and advance that prefix without guessing completion. +- Attention keys are scoped to the binding. Repeated requests correlate to one + item and its first source cursor; conflicting request/message correlations are + rejected. Resolution explicitly names the key. A new question requires a new + key; a replay cannot reopen a resolved item. Resolving one request preserves + waiting status while another request remains pending; resolving the last leaves + native status unknown until new evidence arrives. Attention state is separate + from native activity and delivery state. +- Capability results distinguish `proved`, `partial`, `unsupported`, and + `unknown`; absent capabilities stay unknown. Proved/partial results require + an evidence reference and fixture/live scope. Unsupported results are returned + as typed records with no fallback operation. Optional provider metadata is a + typed extension; absent model, effort and usage remain absent. +- Checkpoints contain the contiguous evidence cursor, latest observed native + status, source timestamp when available, attention, pending attempts, and + caller-supplied repository/candidate references. Those references do not prove + publication or review acceptance. Replay uses historical events plus attempt + snapshots and the binding's current generation, with no model call. + +## Evidence and limits + +`backend/tests/runtime/test_contracts.py` contains synthetic unittest cases for +logical and attempt ID conflicts, disconnect uncertainty, evidence-gated retry, +stale ownership, duplicate and out-of-order events, attention correlation, +unsupported capabilities, malformed input, and checkpoint reconstruction. +These are contract examples, not recordings of real Codex or Claude interfaces. +The implementation handoff does not claim the suite has executed. + +The controller should run from the repository root: + +```sh +uv run --project backend python -m unittest discover -s backend/tests/runtime -p test_contracts.py +``` + +Require a nonzero test count and successful assertions; empty discovery is not +acceptance evidence. Controller lint and later integrated adapter checks remain +separate gates. No live-provider capability is established by this slice. + +This reference store is not thread-safe or durable and does not survive process +loss by itself. A production store needs transactions, uniqueness constraints, +authenticated evidence, append-only attempt history and ownership authorization. +There is no network delivery, automatic retry, provider adapter, process owner, +Kubernetes operation, subscription use, or change to existing call paths here. diff --git a/models/src/models/__init__.py b/models/src/models/__init__.py index

only. This +document does not claim a live Codex proof, production wiring, transport +ownership, or subscription-backed capability. + +## Boundary + +`backend/src/mainloop/runtime/codex.py` is a side-effect-free adapter. It +accepts a source envelope containing: + +- `source_cursor`: a positive integer supplied by the source; the adapter does + not allocate, renumber, or sort cursors; +- `raw_evidence_ref`: an immutable reference to the sanitized source record; +- `ingested_at` and optional `source_at` timestamps; +- optional ownership and logical-message identifiers; and +- one native event object using the fixture's `type`/`params` shape, or the + native `method`/`params` shape with an optional JSON-RPC `id`. + +The adapter validates the envelope with the shared native-agent models and +returns `NativeEvent` records. `observe_codex_event` additionally returns a +fixture-local evidence classification and, when present, a delivery signal. +`CodexFixtureAdapter` is only a convenience facade around those pure +functions. 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. Model, effort, runtime version, and +usage values are optional observations: an absent value stays `None`; no +default model, effort, zero usage, or synthetic source reference is created. +`NativeBinding.provider` identifies the bound adapter (`codex`). When the +native thread exposes `modelProvider`, `ProviderExtension.provider` preserves +that observed value (for example, `openai`); if it is absent, the required +extension provider field retains the binding identity without claiming that a +model provider was observed. A structured `params.thread.status` such as +`{"type":"idle"}` is thread state, not a turn terminal status. + +## Normalization covered by the fixtures + +The checked-in records under `backend/tests/runtime/fixtures/codex/` are +sanitized synthetic examples, not copied session logs. The table describes +what the fixture tests prove about this normalizer. + +| Native evidence | Shared event | Fixture result | +| --- | --- | --- | +| `thread/started` | `unknown` | Preserves session/event identity and raw reference; existence is not completion. | +| `thread/started` with structured `params.thread.status` | `unknown` | Accepts native `ThreadStatus` objects such as `{"type":"idle"}` without interpreting them as turn completion. | +| `turn/started` | `activity` | Records observed turn activity and exposes a separate `delivered` signal. | +| `item/*` with `commandExecution`, `fileChange`, `mcpToolCall`, `webSearch`, or compatibility spellings | `activity` | Preserves tool activity without treating it as assistant output. | +| `item/*` with non-empty `agentMessage`/assistant message text or compatibility spellings | `output` | Records output activity only. | +| `turn/completed` or an equivalent explicit completion event | `completed` | Completion is emitted only from an explicit native completion event with no contradictory status or a supported `completed` status. | +| `turn/interrupted` or an explicit interrupted completion status | `interrupted` | Interruption remains distinct from completion. | +| terminal event with `inProgress` or an unrecognized status | `unknown` | Contradictory or unknown terminal status never emits completion or a completed delivery signal. | +| empty message/terminal output or idle/keepalive evidence | `unknown` | Classified as `quiet`; it never claims completion. | +| explicit request with a complete attention payload | `attention` | Preserves the request and optional logical-message correlation. | +| explicit attention resolution with a key | `attention_resolved` | Resolves only the named shared-contract attention key. | +| `item/commandExecution/requestApproval`, `item/fileChange/requestApproval`, `item/permissions/requestApproval` with the JSON-RPC `id` and `params.threadId`, `turnId`, `itemId` | `attention` (`approval`, `boolean`) | Complete payloads only. The command, file, or permission details are not interpreted or required. | +| `item/tool/requestUserInput` with the ids above and exactly one plain question | `attention` (`question`, `text` or `choice`) | Option labels become choices. Multiple questions, secret questions, empty or duplicate options, and options that also allow free text stay unknown. | +| `serverRequest/resolved` with `params.threadId` and `params.requestId` | `attention_resolved` | Resolves the request with the same thread and request ID. | +| native request or resolution that is incomplete, for another thread, or of an unsupported method | `unknown` | Keeps cursor, native type, and raw evidence; creates no attention item. | +| Any event with a foreign `params.threadId` or `params.thread.id` | `unknown` | Preserves raw evidence but cannot change this binding's activity, delivery, attention, or completion state. | +| `params.thread.modelProvider`, model, and `params.turn.effort` | `activity`/observed metadata | Preserves native model/provider/effort values without replacing an observed provider with the binding identity. | +| `thread/tokenUsage/updated` with `params.tokenUsage` or compatibility usage shapes | `usage` | Preserves non-negative input/output counts only when present. Native `last` counts are read before `total` counts when both are present. | +| compaction/resume/context evidence | `continuation` | Records an observation; the adapter does not implement compaction or continuation. | +| unrecognized native type | `unknown` | Retains native type, cursor, and raw evidence reference without guessing semantics. | + +Receipt, delivery, completion, and interruption signals are returned as +fixture-local `CodexDeliverySignal` values. 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::`, 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. + +## 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. + +| 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 | +| Discovery, creation, transport ownership, steering, and process lifecycle | unknown/unsupported in this adapter | requires a gated live proof | + +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.

+Status: implemented as a sanitized fixture-backed normalizer only. This slice +does not start Claude, use a subscription, import the Claude Agent SDK, or wire +the adapter into a production call path. `ROADMAP.md` remains the intended +architecture; the existing `claude-agent/` worker and its SDK entrypoints are +unchanged. + +## Boundary + +`backend/src/mainloop/runtime/claude.py` accepts a small fixture envelope around +JSON-shaped native Claude observations: + +```json +{ + "source_cursor": 2, + "raw_evidence_ref": "fixture://claude/stream.json#cursor-2", + "source_at": "2026-01-01T00:00:01+00:00", + "event": { + "type": "assistant", + "uuid": "claude-event-output-002", + "session_id": "claude-native-session-fixture", + "message": {"content": [{"type": "text", "text": "..."}]} + } +} +``` + +The envelope is test/runtime evidence, not a claim that Claude itself emits a +numeric cursor or a `fixture://` URI. The runtime that owns the native stream +must provide a stable source cursor and raw-evidence reference. Reconnects must +reuse the source cursor; the shared `ContractStore` handles duplicate +suppression, ownership fencing, source gaps, and checkpoint projection. + +The input vocabulary follows the locally available native Claude stream types: +`system`, `assistant`, `user`, `stream_event`, `result`, and the control +protocol's `control_request`/`control_response` records. The adapter uses plain +Pydantic validation and does not import or execute the SDK that defines those +types. + +## Normalization + +| Native observation | Shared event | Evidence rule | +| --- | --- | --- | +| `system.init` | `activity` | Requires a session ID when building a binding; the binding preserves it. | +| Assistant text | `output` | Text is activity/output, never completion by itself. | +| Tool/thinking or other assistant activity | `activity` | Tool input is not interpreted as a product command. | +| `stream_event` content/message updates | `output` or `activity` | A stream stop marker is not completion. | +| `result` with `subtype=success` and `is_error=false` | `completed` | Both explicit success and the non-error flag are required. | +| Explicit result error | `interrupted` | An error result is not a successful completion; `interruption.json#cursor-3` proves the fixture projection. | +| `control_request` with `can_use_tool` | `attention` | A request ID is the correlation key for a pending boolean approval. | +| Successful permission `control_response` with nested `response.behavior=allow/deny` | `attention_resolved` | Only explicit permission evidence and its request ID resolve attention. | +| Other successful `control_response` records | `unknown` | Initialization, hooks, and permission-mode acknowledgements are not attention resolutions. | +| `system.compact_boundary` | `continuation` | The observation does not implement or prove native resume behavior. | +| Explicit `transport.lost` | `transport_lost` | The checkpoint becomes unknown; no retry or replay is implied. | +| Unrecognized but structurally valid type | `unknown` | The native type, cursor, and raw evidence reference remain available. | + +`process_exit` and `quiet` are runtime observations rather than native stream +events. `ClaudeSessionNormalizer.observe_runtime()` retains their evidence and +does not turn either into `completed` or advance the native event journal. +Quiet output therefore leaves the last native status active until stronger +evidence arrives; process exit leaves native completion unproven. Transport +loss is distinct because it is an explicit normalized event that projects an +unknown native status. + +Provider metadata is optional. The adapter preserves a native event UUID, +model, runtime version, effort, and input/output token counts only when present +and valid. Missing usage, model, or effort stays `None`; no zero, default model, +cost, or inferred receipt is created. A native session ID that is present on an +event must match the bound session. + +## Capability evidence + +The adapter exposes `claude_fixture_capabilities()` so callers can keep +fixture-backed claims separate from live-provider claims. + +| Capability | State | Scope | Fixture evidence | Live status | +| --- | --- | --- | --- | --- | +| Session identity | proved | fixture | `stream.json#cursor-1` | Native discovery/attachment still needs live proof. | +| Cursor ordering and reconnect deduplication | proved | fixture | `stream.json#cursor-2` | Runtime cursor durability and authenticated reconnect are unproved. | +| Native completion parsing | proved | fixture | `stream.json#cursor-7` | A live Claude result/completion guarantee is unproved. | +| Interruption projection | proved | fixture | `interruption.json#cursor-3` | Live error, cancellation, and process semantics are unproved. | +| Permission attention request | partial | fixture | `stream.json#cursor-4` | Live exposure, user reply delivery, and resolution are unproved. | +| Usage observation | partial | fixture | `stream.json#cursor-2` | Completeness, attribution, and billing semantics are unproved. | +| Continuation observation | partial | fixture | `stream.json#cursor-6` | Native context continuation/resume behavior is unproved. | +| Delivery receipt | unsupported | fixture | No receipt record in the fixture | Requires a separately proven native/runtime signal. | +| Steering | unsupported | fixture | No send operation in this adapter | Requires an explicit runtime delivery contract. | +| History export | unsupported | fixture | A stream is not a history export | Native history ownership remains with Claude. | +| Live native behavior | unknown | unverified | No provider process was started | Must be established by a separate, authorized proof. | + +`proved` and `partial` in this table mean that the normalizer behavior is +covered by sanitized fixtures. They do not mean that the corresponding live +Claude capability has been established. + +## Existing SDK separation + +The current `backend/src/mainloop/claude_agent.py`, +`backend/src/mainloop/services/claude_agent.py`, and `claude-agent/` service use +the existing Claude Agent SDK worker. This adapter does not call those modules, +does not parse their result wrapper as native evidence, and does not change +their production behavior. Replacing those paths requires a later architecture +decision backed by live native proof. + +## Required live proof later + +Before production wiring, a separately authorized proof must establish native +session discovery/creation, logical-message receipt, completion, attention or +an explicit unsupported result, cursor reconnect, duplicate suppression, +interruption, usage/context signals, and uncertain-send reconciliation. The +proof must use a disposable session, preserve private raw evidence outside the +repository, and classify every capability as proved, partial, unsupported, or +unknown.

Status is answered from Postgres and adds no native turns. Behind MAIN_THREAD_MODE=native; the SDK chat path is unchanged and stays the default. Local-kind only: the spike-herdr overlay and spikes/ are local exceptions to GitOps. Known gap: the per-binding token is not a security boundary while the rest of the backend API is unauthenticated.
