From a6666248fac84b7270d06a2c3b84dcc57663cce1 Mon Sep 17 00:00:00 2001 From: Anatolii Date: Tue, 11 Aug 2026 17:31:04 +0400 Subject: [PATCH 01/16] cleanup(sprint3): remove dead code, redundant tests, memoir comments, dup CHANGELOG MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit P1 — dead code: - Remove deprecated start_recording/stop_recording no-op stubs from runtime.py (replaced by direct return-value gates; tests for them removed). - Delete breaker/__main__.py stub (was a no-op CLI entry point). - Delete unused import warnings in runtime.py after the deprecated stubs. P2 — redundant tests: - Delete one-shot fix-dump tests (test_.py) whose only purpose was to bump coverage for a single audit/fix commit: test_blocker_fixes, test_high_reliability_fixes, test_medium_hygiene_fixes, test_release_polish, test_drift_fixes_2026_07_04, test_kill_deprecation. - Delete obsolete tests: test_dead_code_removed (the audited code is gone), test_breaker_main (its stub target was deleted), test_grpc_removed (no gRPC code exists), test_kill_contract, test_legacy_key_warning. - Consolidate test_X_branches.py into test_X.py: test_runtime_branches, test_transport_branches, test_protect_branches, test_actions_context_init. - Consolidate test_v3_server_minted.py and test_v3_38_drift_fixes.py into test_v3_wire_contract.py. P3 — memoir comments: - Strip historical-context / fix-narrative / ADR-reference / pre-fix commentary from 90% of files (transport.py / runtime.py / decorators.py / breaker/exceptions.py / observability/__init__.py / test_runtime.py / test_protect.py / test_actions.py / test_transport.py / test_v3_wire_contract.py / conftest.py). Docstrings compressed to 1-2 lines per method; inline marker comments (T4 (...), P0-4, FIX-F3, PR #N, 2026-07-02, ADR-008, observed: ..., pre-fix, ...) collapsed to a single short line. - Replace 'Merged from X.py' section markers with semantic headers. P4 — CHANGELOG deduplication: - src/nullrun/__version__.py: 1192 -> 9 lines (kept just the version constants; the full release history lives in CHANGELOG.md). - pyproject.toml: removed ~180 lines of inline release-history comments duplicated from __version__.py; only the current version is pinned.

The marker - ``@pytest.mark.rerunfailures(reruns=2)`` on - ``tests/test_approval_timeout_field.py::TestApprovalTimeoutResolution - ::test_env_fallback_when_server_value_is_zero`` (a thread-scheduling - race in the approval-wait fixture under ``-n auto`` on shared CI - runners — local sequential runs pass 15/15) was a silent no-op - on the coverage job, and the first race in the spawn-vs-release - window turned the run red even when the ``test`` (3.10/3.11/3.12) - matrix was fully green. The marker itself - (``reruns=2``, ``release_after_ms=200``) was already in place - from the audit — the missing piece was the plugin on the - coverage leg. This release matches the install on - ``ci.yml:41-45``. - -2. ``tests/test_actions.py::TestPauseAction::test_is_paused_respects_cooldown`` - closed a second pre-existing flake flagged in the 0.13.7 - changelog. The test asserted ``is_paused(..., cooldown_seconds=0.0)`` - returns ``False`` immediately after a ``PAUSE`` action — but the - underlying ``is_paused`` computes ``elapsed = time.time() - paused_at`` - and returns ``True`` while ``elapsed > cooldown`` (strict greater - than). On any platform where ``time.time()`` rounds to the same - integer as ``paused_at`` within the test body — Windows, WSL1, - and the shared CI runner when the OS scheduler happens to round - down — ``elapsed == 0.0`` and the workflow stays "paused" forever, - failing the assertion. Pre-0.14.6 this was rare-flaky - (``1 in 1142`` per 0.13.7 changelog); on the 0.14.5 runner pool - it became ``5 in 5``. The test now sleeps ``0.01s`` between the - ``PAUSE`` handle and the post-cooldown assertion to make the - ``elapsed > 0.0`` check deterministic. No production behaviour - change: the only call site that uses ``cooldown_seconds=0.0`` is - this test, and ``ActionHandler.is_paused`` is an internal helper. - -Tests: - - * Full suite green on local ``pytest tests/`` after both fixes: - 1417 passed, 7 skipped, 10 warnings. - * ``ruff check src/ tests/`` -- All checks passed. - * ``mypy src/`` -- Success: no issues found in 37 source files. - -No public API change. No on-wire change. No SDK_MIN_VERSION bump. - --- - -v3.31.4 / 0.14.5 (2026-08-01) — MCP metadata and tool-argument -forwarding. - -This release completes the SDK-side path for MCP-aware gate -policies and schema-drift fingerprints: - - * ``set_mcp_tool_context`` stores the canonical tool class and - MCP ``tools/list`` annotations in per-call context variables. - ``NullRunRuntime.check_workflow_budget`` forwards populated - values as optional ``tool_class`` and ``mcp_annotations`` - fields on ``/check``. - * ``MCPAdapter`` wraps a connected synchronous MCP client, - caches ``tools/list`` metadata for 300 seconds, normalises - ``readOnlyHint`` / ``destructiveHint`` / ``openWorldHint``, - stamps the context before each call, and delegates the call - without changing the client's result or exception surface. - * ``Transport.execute`` accepts optional ``tool_arguments``; - ``Transport.check`` forwards the same field from its request - mapping. The backend can use this JSON argument bag to compute - and record a stable tool-schema fingerprint. - -All new wire fields are optional and omitted when unavailable, so -existing callers and older SDK integrations preserve their prior -request shape. MCP annotations remain an honest-client signal; -the SDK does not independently verify a server's declarations. -The adapter does not implement MCP transports or JSON-RPC and does -not auto-collect arguments for arbitrary callers. - ---- - -v3.30 / 0.14.4 (2026-07-27) — ToolParameters Approval Rules -wire contract. - -Pre-fix 0.14.0, a ``track_tool`` event payload containing a -``Decimal`` (e.g. ``refund_amount`` from a -``@sensitive(impact=money_outflow(units="major"))`` body) -raised ``TypeError: Object of type Decimal is not JSON -serializable`` from the inner ``json.dumps`` call. The -exception was raised in BOTH the canonical signed-body -serializer AND the on-disk WAL fallback log; both silently -dropped the event, so the dashboard showed no -``refund_customer`` cost_events even though the body ran -successfully. - -Fix (one-liner on each call site): - - * ``transport.py:251`` ``_signed_request_body(payload)`` now - calls ``json.dumps(payload, separators=(",", ":"), - default=str)``. Pre-fix events that serialised cleanly - still serialise to the same bytes because ``default=`` is - only consulted when the default encoder fails. - * ``transport.py:711`` WAL fallback ``f.write(json.dumps - (event) + "\n")`` also gets ``default=str`` for - consistency. The on-disk fallback log is read by ops only - when the backend is unreachable, so the wire-format - guarantee does not apply here. - -Decimal is now serialised as its lossless string -representation (``"50.99"`` on the wire), and the backend's -pricing math runs on the same string. Other non-JSON-native -types (``bytes``, ``datetime``, ``UUID``) get the same -``str()`` fallback so a single encoder pass handles them -all. - -Verification: - - * ``_signed_request_body({"events": [{"type": "tool_call", - "refund_amount": Decimal("50.99"), ...}]})`` returns a - 140-byte payload with ``"refund_amount":"50.99"`` on the - wire. Pre-fix code raised ``TypeError`` at the same call - site. - * The existing track_tool / sensitive_extractor contract - suite passes unchanged (the wire-format bytes match for - any payload without ``Decimal``). - * ``pytest tests/test_sensitive_extractor.py`` -> 5/5 pass. - * ``pytest -n auto --cov=src/nullrun --cov-branch - --cov-report=xml --cov-fail-under=0`` -> 1367 passed, - 7 skipped, 29 warnings in 33.24s, cov 81.49%. - -Backward-compatible bug fix. No SDK_MIN_VERSION bump. No -public API change. The wire shape is preserved for every -pre-fix event (a non-Decimal payload serialises to the same -bytes); the Decimal serialisation is a strict superset. - ---- - -v3.28 / 0.14.0 (2026-07-23) — hardening pass on the money contract. - -Closes the four review gaps from the UX follow-up: - - 1. **Dedicated error types** -- ``InvalidMoneyPrecisionError`` - and ``InvalidMoneyAmountError`` (both subclass - ``ValueError`` for backward compat). The ``amount`` variant - carries a ``reason`` discriminator (``"negative"`` / - ``"overflow"`` / ``"non_finite"``) so a UI or test harness - can branch on type without parsing the message. The - ``precision`` variant carries ``currency`` / ``allowed`` / - ``received`` / ``received_digits`` so the error message - names the offending currency and precision. - - 2. **Negative amount rejection** -- a negative ``amount_minor`` - would silently fall through every ``op=gt`` predicate - (``negative < positive`` is always False), so the SDK - rejects ``Decimal("-50.00")`` / ``int(-5000)`` / - ``Decimal("-5000")`` on both unit paths with - ``InvalidMoneyAmountError(reason="negative", ...)``. ``0`` - is accepted (legitimate $0.00 refund). - - 3. **Sub-precision Decimal rejection** -- ``Decimal("1.234")`` - against a USD ``allowed=2`` precision is now - ``InvalidMoneyPrecisionError(currency="USD", allowed=2, - received=3, received_digits="1.234")`` instead of a silent - round to ``1.23`` that drops the high-order digit the user - explicitly typed. ``float`` and ``Decimal`` are treated - symmetrically; ``int`` always rounds 0-digits. - - 4. **Explicit ``units`` discriminator + ``Decimal`` support** - -- a new ``BusinessImpact`` model + ``MoneyImpactExtractor`` - + ``@sensitive(impact=...)`` decorator wiring allows the - caller to declare the impact currency / units on - ``@sensitive``-decorated functions and have the SDK emit - a structured ``business_impact`` envelope on the - ``/track`` event, replacing the previous free-form - ``details`` blob. ``Decimal`` values are accepted and - normalised to ``Decimal`` minor-units on the wire. - -Side fixes (covered by the same audit pass): - - * ``/execute`` now handles ``require_approval`` correctly - and re-checks with the ``approval_id`` returned by the - backend (was dropping the approval handshake on - round-trips). - * Server's ``approval_timeout`` is clamped to ``[1, 3600]s`` - on the SDK side as defence against a malformed / - overshooting backend that returns ``0`` or ``2147483647`` - in the server approval-timeout field. - -Public API change (additive only, backward-compatible): - - * ``InvalidMoneyPrecisionError``, ``InvalidMoneyAmountError`` - -- new ``ValueError`` subclasses with structured fields. - * ``BusinessImpact`` -- new ``dataclass(frozen=True)`` model - with explicit ``currency`` / ``units`` / ``amount_minor`` - fields. ``details`` dict is still accepted (legacy path). - * ``@sensitive(impact=BusinessImpact(...))`` -- new - decorator kwarg. Existing ``@sensitive(details=...)`` / - ``@sensitive(amount_minor=..., currency=...)`` callers keep - working on the happy path (now routed through - ``BusinessImpact`` internally). - -Tests (existing suite still green; new test modules land in -``tests/test_business_impact.py`` / -``tests/test_units_discriminator.py`` / -``tests/test_money_hardening.py`` / -``tests/test_sensitive_extractor.py`` / -``tests/test_approval_money_flow.py`` / -``tests/test_execute_approval_flow.py``): - - * 5 Definition-of-Done scenarios cover negative-amount - rejection, sub-precision Decimal rejection, overflow - rejection, non-finite rejection, ``0`` accepted. - * Units discriminator test: ``USD`` vs ``USDT`` collision is - now caught at the ``BusinessImpact`` boundary, not on the - backend at ``/track`` time. - * ``/execute`` round-trip test exercises the - ``require_approval`` + ``approval_id`` re-check path with a - stub backend. - * Server ``approval_timeout`` clamp test verifies - ``[1, 3600]s`` boundary. - * 5 contract tests cover the ``MoneyImpactExtractor`` path - end-to-end. - -Verification (local): - - * ``pytest tests/test_money_hardening.py - tests/test_business_impact.py tests/test_units_discriminator.py - tests/test_sensitive_extractor.py - tests/test_approval_money_flow.py - tests/test_execute_approval_flow.py`` -- all new tests - pass; no regressions in the existing suite. - * ``ruff check src/ tests/`` -- All checks passed. - * ``mypy src/`` -- Success: no issues found in 34 source - files. - -No SDK_MIN_VERSION bump (legacy backends unaffected). No on-wire -change (envelope shape preserved). New errors are ``ValueError`` -subclasses, so legacy ``except ValueError:`` blocks still catch -them. - ---- - -v3.27 / 0.13.13 (2026-07-21) — approval-timeout wire sync. - -Backend commit ``0ad03b9`` (gate hot-path trigger that prompted -this SDK sync) added ``approval_timeout_seconds: Option`` -and ``approval_expires_at: Option`` to the GateResponse -wire format. Before this SDK fix, the approval wait path used -``NULLRUN_APPROVAL_TIMEOUT_SECONDS`` env default (default -300s) as the ONLY source of wait duration — which is exactly -the silent-desync class of bug that the backend sweeper was -written to prevent on the backend side. - -Concretely: a backend approval rule configured with -``expires_in_seconds=20`` (short-approval use case) would -have the backend's expiry sweeper close the row at 20s, but the -SDK would have timed out the parked gate call at 300s — a -silent desync. The 300s/300s coincidence worked only because -no UI-1 yet exists to set non-default expirations, and because -the env default matched the backend default. - -Fix (no on-wire change, backward-compatible API): - - * ``runtime._wait_for_approval_resolution``: new optional - kwarg ``timeout_seconds: float | None = None``. When set - to a positive number, used as the event.wait() timeout - (server-authoritative, takes precedence over the env - default). When ``None`` (legacy backend without the - server-side approval-timeout field, or malformed response), - falls back to ``self._approval_timeout_seconds`` (env - default) — pre-server-side behaviour preserved. When set - to a non-positive number (0 or negative), also falls back to - env default; we explicitly reject these because - ``event.wait(timeout=0)`` deadlocks on the very first call. - - * ``runtime.check_workflow_budget``: reads - ``response["approval_timeout_seconds"]`` (server value), - validates the type (must be a number) and sign (must be - positive), and falls back to ``None`` on any validation - failure. ``approval_expires_at`` is intentionally not - parsed in the SDK (informational only; the SDK's wait math - doesn't need it). - - * When the server value diverges from the env default, a - DEBUG log line is emitted ("approval {id}: using server - timeout={X}s (env default would have been {Y}s)") for - diagnostic visibility. - -Tests (existing suite still green; new tests in -``tests/test_approval_timeout_field.py``): - - * 6 new tests cover server-timeout-used, env-fallback on - missing/zero/negative/non-numeric values, sentinel- - returned-when-no-ws-push, and diverging-server-value - log line. Pairs with backend commit ``0ad03b9``. - -Verification: - - * ``pytest tests/test_approval_timeout_field.py`` — - 6 passed. - * ``pytest -n auto --cov=src/nullrun --cov-branch - --cov-report=xml --cov-fail-under=0`` — - 1243 passed, 7 skipped, 28 warnings in 34.44s - (coverage 80.92%). - * ``ruff check src/ tests/`` — All checks passed. - * ``mypy src/`` — Success: no issues found in 34 source - files. - -Backward-compatible public API change. No SDK_MIN_VERSION bump. -No on-wire change. - ---- - -v3.26 / 0.13.12 (2026-07-20) — CI / coverage-testability release. - -The pytest suite now runs a `_fast_sleep` autouse fixture in -``tests/conftest.py`` that caps test-code ``time.sleep`` calls at -1ms, with two opt-out paths: ``@pytest.mark.slow_sleep`` on a -test/class (e.g. ``TestPingChainScheduler``) or the -``NULLRUN_FAST_SLEEP=0`` env var. The three -``TestCircuitBreaker`` half-open tests that previously used a -bare ``time.sleep(1.1)`` to wait out the 1.0s recovery_timeout -now drive the wall clock via a ``_advance_clock(monkeypatch)`` -helper that patches ``time.monotonic`` instead — deterministic -across xdist workers and zero wall-clock cost. - -Net effect: ``pytest -n auto`` coverage on master dropped the -3.3-second per-test wall-clock tax on ``TestCircuitBreaker`` -(only on Windows where xdist is single-worker-bound) and the -suite goes from "almost-hangs" to ~35s end-to-end. CI scope only; -no on-wire change, no SDK_MIN_VERSION bump, no public API -change. - -Coverage report (local): 80.79% combined (master 29caae9 was -reported as 79.26% by Codecov because the pre-fix CI uploaded a -coordinator-only 0% report; this release keeps the 80% floor in -``.codecov.yml`` and the new combined report is what the -Codecov badge will render against the master branch). - ---- - -v3.25 / 0.13.11 (2026-07-14) — forward 5 vendor-extractor fields -through the v3 /track single-event payload. - -Pre-fix (0.13.10) the vendor-specific extractors surfaced -``cache_read_tokens``, ``cache_write_tokens``, -``reasoning_tokens``, ``finish_reason``, and ``tool_names`` -onto ``wire_event`` correctly, but -``runtime._build_v3_track_payload`` did NOT opt those five -fields into the explicit v3 payload dict it constructs. The -legacy ``/track/batch`` path serializes the event as-is and -preserved the fields; the v3 path dropped every one of them -on the SDK wire boundary. - -Effect on the backend: migration 220 added the five columns -to ``cost_events`` (cache_read_tokens, cache_write_tokens, -reasoning_tokens, finish_reason, tool_names), the v3 -``/track`` handler deserialised ``None`` for every column -on every LLM call routed through the v3 path, and the -dashboard's reasoning / cache / finish_reason metrics -returned zero for every event on the v3 single-event path. - -Fix (no public API change, no wire-format change): - - * ``runtime._build_v3_track_payload``: append a second - opt-in pass for the five vendor-extractor fields, using - the existing ``if k in wire_event and wire_event[k] is - not None: payload[k] = wire_event[k]`` pattern that - already opts in ``agent_id`` / ``environment`` / - ``agent_type`` / ``attempt_index`` / ``is_retry``. The - backend defaults all five fields to ``None`` on missing - keys, so legacy events that land on the v3 path without - these fields still parse cleanly. - -Wire format: unchanged. Backends on 1.0.0 keep working -unchanged. Pinning unchanged: SDK_MIN_VERSION_FOR_V3 = -"0.12.0". Recommended upgrade path: 0.13.10 -> 0.13.11. - -Tests (existing suite still green; no new test files): - - * tests/test_v3_wire_contract.py — 36 tests cover the - existing opt-in pattern (agent_id / environment / - agent_type / attempt_index / is_retry); the new keys - ride through the same branch and the - ``test_build_v3_track_payload_*`` suite covers the - round-trip. No new wire-format tests needed — the - mapper-level coverage is identical to the existing - opt-in keys. - -Verification locally (origin/master + eb1bb6f on top): - - * pytest tests/test_extractors.py tests/test_crewai_patch.py - tests/test_runtime.py tests/test_runtime_branches.py - tests/test_track_batch_retry.py - tests/test_track_span_context.py - tests/test_v3_wire_contract.py tests/test_release_polish.py - — 185 passed, 1 skipped (no regression vs 0.13.10). - * ruff check src/ — "All checks passed!". - * mypy src/nullrun — Success: no issues found in 34 source - files. - -No public API change. No SDK_MIN_VERSION bump. - ---- - -v3.24 / 0.13.10 (2026-07-13) — close 5 vendor extractor edge cases -missed in the 0.13.9 audit. - - 1. Cohere v2 tool_calls path: the pre-0.13.10 extractor read - top-level payload["tool_calls"], but Cohere v2 nests the field - under message.tool_calls (OpenAI shape). Every v2 Cohere call - shipped with tool_names=[] and the backend's loop detection - could not see Cohere tool use. Fix walks both v1 (top-level) - and v2 (message.tool_calls) paths. Same patch adds - usage.tokens.cached_tokens (cache-hit read was always 0) and - the UPPERCASE finish_reason vocabulary - (COMPLETE | MAX_TOKENS | TOOL_CALL) — the _FINISH_REASON_MAP - already lower-cased both vocabularies; the missing piece was - the test snapshot. - - 2. Mistral num_cached_tokens (flat field on usage, not nested - under prompt_tokens_details.cached_tokens like OpenAI's). The - OpenAI extractor only read the nested shape, so Mistral - customers always saw cache_read_tokens=0 even when the - inference cache hit. Fix reads the Mistral flat field as a - fallback inside the same chain. The _openai_extractor host - map (line 567) already covers Mistral so no host-routing - change was needed. - - 3. Gemini 2.5+ thoughtsTokenCount (reasoning tokens in - usageMetadata) — was hard-coded to 0, so thinking-mode Gemini - calls had no visible reasoning column on the dashboard. - Surfaced as reasoning_tokens while the total stays at - totalTokenCount (reasoning tokens are part of - candidatesTokenCount upstream). - - 4. Anthropic 4.5+ output_tokens_details.thinking_tokens - (extended-thinking mode) — was hard-coded to 0 for the same - reason. The pre-0.13.10 comment ("reasoning tokens are part - of output_tokens") was correct for the non-thinking baseline, - but the thinking-mode field was still readable and was being - dropped. Now we read the breakdown while keeping the total at - input+output (Anthropic bills thinking tokens at the output - rate upstream). - - 5. AWS Bedrock finish_reason for the Mistral-on-Bedrock / - OpenAI-compat and Llama-on-Bedrock adapter shapes. The - pre-0.13.10 extractor only read top-level stopReason / - stop_reason (Anthropic + Llama top-level). Mistral's - OpenAI-compat shape puts the field under - choices[0].finish_reason and was always None. The - matched_shape discriminator (already tracked in the - tool-detection block) tells us which body to read from and - the new branch picks choices[0].finish_reason when - matched_shape == 'openai_choices'. - -The same audit identified the following as should-fix but -deferred to a follow-up PR (none is a billing gap; all are -visibility / observability gaps): - - - Anthropic cache_creation.ephemeral_{1h,5m}_input_tokens - TTL breakdown (different billing rates; Bedrock does not - yet expose the breakdown as of 2026-Q3). - - Anthropic server_tool_use.{web_search_requests, - web_fetch_requests} — server-side tool invocations not - visible to loop detection. - - Gemini multimodal *TokensDetails[] (TEXT vs IMAGE vs - AUDIO) — image-heavy calls mask the real cost driver. - - Cohere billed_units.{search_units, classifications} for - RAG / classify workloads. - - Cohere reasoning models (command-a-reasoning-*). - - Bedrock Converse API (separate envelope from InvokeModel). - -Wire format: unchanged.

No SDK_MIN_VERSION bump. - ---- - -v3.23 / 0.13.9 (2026-07-13) — crewai 1.15 compatibility + gate_cache -re-capture. - - 1. crewai 1.15 removed the ``step_callback`` and - ``task_callback`` keyword parameters on - ``Crew.kickoff()``. The pre-0.13.9 patch injected - ``kwargs["step_callback"]`` into the wrapped call, which - now raises ``TypeError: Crew.kickoff() got an unexpected - keyword argument 'step_callback'`` and kills the agent - loop before ``crew.usage_metrics`` is read. - - 0.13.9 replaces the callback-injection path with an - event-bus bridge: ``nullrun.instrumentation.crewai`` - subscribes to ``CrewKickoffStartedEvent`` / - ``CrewKickoffCompletedEvent``, - ``AgentExecutionStartedEvent`` / - ``AgentExecutionCompletedEvent``, - ``TaskStartedEvent`` / ``TaskCompletedEvent`` / - ``TaskFailedEvent``, ``LLMCallStartedEvent`` / - ``LLMCallCompletedEvent``, and - ``ToolUsageStartedEvent`` / ``ToolUsageFinishedEvent`` via - ``crewai_event_bus.scoped_listener(EventBusListener)`` and - translates each event into the existing - ``runtime.track_event`` shape (``span_start`` / - ``span_end`` per kickoff / agent / task / llm / tool). - Token totals still come from - ``crew.usage_metrics`` post-kickoff — the post-run - ``track_llm`` emission is unchanged so the dashboard sees - the canonical ``(model, prompt, completion)`` tuple on - every billable row. - - When ``crewai.events`` is not importable (pre-1.15 crewai - or a stripped-down third-party build) the post-run - ``usage_metrics`` wrap is still installed and the patch - returns ``True`` so callers that gate on - ``\"did nullrun.init register a crewai bridge\"`` keep - getting a positive answer; only the per-event span - bridge is a no-op. - - 2. ``check_workflow_budget`` re-runs - ``_capture_server_minted_execution_id`` on the - ``_GATE_CACHE`` cache-hit branch (runtime.py:1486). - Pre-0.13.9 the cache-hit path returned the cached - response directly without re-capturing - ``reservation_id`` / ``operation_id`` into the - server-minted contextvars. Symptom on the wire in - chain-mode multi-call loops: every ``/track`` inside - the 5s cache TTL shipped the same ``idempotency_key`` - (the first call's ``operation_id``) with different - request bodies, the backend stored the body hash on the - first call and returned 409 ``idempotency_key hash - mismatch`` on every subsequent call, and the SDK dropped - every event at runtime.py:2649 (zero rows reaching - Postgres). Re-running the capture on cache hit is the - missing piece — the cached response dict is identical but - the contextvar is properly refreshed each time so the - next ``_route_track`` reads a fresh ``reservation_id``. - - Note: this fixes the per-call contract for the v3 - /track single-event path. Chain-mode loops that re-use - the *same* chain_id across many gate calls still rely on - the cache collapsing to one roundtrip, which is the - intentional design (BUG #5 — gate_cache - debounce).

The child SpanContext inherits - trace_id from the parent chain / agent per the existing - SpanContext invariant — so a multi-span run shares one - trace_id and the parent_span_id walks the agent tree. - 2. on_llm_end looks that child SpanContext up in - _active_runs[llm_run_id] and passes trace_id / span_id / - parent_span_id explicitly into runtime.track_event, so - _enrich_event forwards them on the wire (alongside - parent_trace_id, the new field). - 3. runtime._enrich_event now sets parent_trace_id = the - child span's trace_id (which equals the parent chain's - trace_id by invariant) on llm_call cost events. The - backend's cost_events.parent_trace_id column (migration - 217, nullable UUID) persists it; the unified SELECT - third JOIN arm (`cs.join_kind = 'parent_trace_id'`) - picks it up and surfaces the LLM model / tokens / cost - on the orchestration row that owns the call. - 4. The new field is wire-additive: legacy backends that - don't read it still receive /track payloads and store - them (the field is dropped on the SQL bind if the column - is absent, but the migration is shipped in lockstep - with this SDK release so production environments have - it). On legacy SDKs that don't set parent_trace_id the - column stays NULL and the unified SELECT falls through - to the existing execution_id / trace_id arms (no - regression). - -Tests: - * tests/test_langgraph_callback.py: - - test_on_llm_start_then_end_attaches_parent_chain_trace_id - - test_on_llm_end_outside_active_chain_still_emits_event - - test_on_llm_end_runtime_failure_is_swallowed - * 39 pre-existing tests in test_langgraph_callback.py still - pass; no regression in test_extractors.py, - test_instrumentation_phase41.py, or the wider suite. - -Wire format: backward-compatible. The new field is serde(default) -absent on older SDKs and ignored by older backends. Operators -upgrading from 0.13.5 must upgrade both sides together (SDK to -0.13.6 + backend with migration 217); the SDK alone still works -on 1.0.0 backends (the field is just dropped at the SQL bind). - -No SDK_MIN_VERSION bump. Recommended upgrade path: 0.13.5 -> -0.13.6. - ---- - -v3.12 / 0.12.0 (2026-07-03) — server-minted execution_id default ON. - -The backend `gate_reserve_v3` now mints a uuidv7 execution_id -internally. This version (`0.12.0`) is the -SDK_MIN_VERSION for the v3 rollout — older SDKs continue to -work because the gate IGNORES the client-supplied execution_id -(it mints its own), but they cannot fully participate in the -v3 /track idempotency contract. - ---- - -v3.12 / 0.12.1 (2026-07-04) — bug-fix: complete the wiring -that 0.12.0 advertised. - -Honest history: the v0.12.0 changelog entry above said "the -SDK no longer needs to generate its own execution_id for -/check; it gets the server-minted one back in the response -and propagates it to /track", but the propagation code was -NOT shipped in 0.12.0. The 0.12.0 wire was correct in intent -but the SDK still routed through /track/batch and ignored -`response["reservation_id"]` (see -`docs/sdk-v3-migration-gaps.md` and audit memory -`sdk-v3-migration-gaps`). - -0.12.1 ships the four missing pieces: - - 1. ``_capture_server_minted_execution_id(response)`` reads - ``reservation_id`` from the /check response into a - contextvar ``nullrun.context._server_minted_execution_id_var``. - 2. ``_enrich_event`` stamps the captured id onto /track - payloads (with a 295s freshness guard so an expired - reservation never ships a doomed id). - 3. ``_route_track`` dispatches ``llm_call`` events to the - v3 single-event endpoint ``/api/v1/track`` via - ``Transport.track_single``, so the backend's - ``gate_consume_v3`` validates the consume-vs-reserve + - ε invariant. - 4. ``NULLRUN_V3_TRACK_DISABLE=1`` opt-out for backends still - on the v1/v2 path. - -Pinning: still SDK_MIN_VERSION_FOR_V3 = "0.12.0". Operators -upgrading from < 0.12.0 should jump straight to 0.12.1 — 0.12.0 -released with the integrity bug above and was never deployed -in production with the v3 wiring. - ---- - -v3.12 / 0.12.2 (2026-07-04) — bug-fix: fresh execution_id -/check + in-process chain-mode gate cache. - -Two related correctness fixes on top of 0.12.1: - - 1. ``check_workflow_budget`` now sends a fresh ``uuidv7`` as - ``execution_id`` on every /check call (instead of reusing - ``workflow_id``). The v3 ``gate_reserve_v3`` mints its - own anyway, but a client-side placeholder that collides - across calls confuses the reservation binding on - /track when ``track_single`` returns 503 - ``RESERVATION_NOT_FOUND``. The server - overwrites the field on response, so the freshly-minted - ``reservation_id`` captured by - ``_capture_server_minted_execution_id`` still drives - /track exactly as in 0.12.1. - - 2. New in-process gate cache - (``nullrun.runtime._GATE_CACHE``) serves chain-mode - @protect calls from a 5s TTL on the same - ``(workflow_id, chain_id, model)`` triple, collapsing - 100-step agent loops to a single /gate roundtrip. Single- - shot (Hard mode) callers bypass the cache — the gate - legitimately flips allow→block between consecutive - calls there, and a stale "allow" could leak a budget- - exhausted call. Opt-out via - ``NULLRUN_GATE_CACHE_DISABLE=1`` for callers that want - the legacy always-roundtrip behaviour (e.g. for live - smoke tests per docs/runbooks/budget-blue-green-smoke.sh). - -No wire-format change.

New contextvar - ``nullrun.context._server_minted_idempotency_key_var`` + - ``get_/set_/reset_/clear_server_minted_idempotency_key`` - ``_capture_server_minted_execution_id`` now also captures - ``response["operation_id"]`` (which equals the /check - idempotency_key, runtime.py:1260); ``_enrich_event`` stamps - the value onto the ``wire_event`` for ``llm_call`` - ``_build_v3_track_payload`` propagates it onto the v3 /track - body with a contextvar fallback for tests + direct callers. - Without this, transport-level retry on the same event either - 503'd with ``RESERVATION_NOT_FOUND`` (reservation key DEL'd - after the first consume per ) or double-billed - the underlying budget. - - 2. Wire ``status_code`` preserved through every decision - exception class. ``NullRunBlockedException`` - ``NullRunBudgetError``, ``NullRunChainError`` - ``NullRunWorkflowInactiveError`` - ``NullRunConsumeOverbudgetError`` now all accept - ``status_code: int | None = None``; ``_parse_v3_error_envelope`` - sets it from ``response.status_code`` for every branch — - 402 budget, 403 workflow/chain cross-org, 422 - ``CONSUME_OVERBUDGET``, 503 ``RATE_LIMIT_REDIS_UNAVAILABLE`` - etc. FastAPI exception handlers reading ``exc.status_code`` - previously got ``None`` / 500 for budget blocks (the backend's - 402 was lost in the constructor chain). - - 3. The runtime.py module docstring now distinguishes - SDK-side transport failure (network/5xx/breaker open → - fail-OPEN on /check) from wire 4xx/5xx that names an - enforcement failure (``BUDGET_REDIS_UNAVAILABLE`` → 402 - fail-CLOSED; ``RATE_LIMIT_REDIS_UNAVAILABLE`` → 503 - fail-CLOSED).

Now delegates to ``Transport.check`` - which targets ``/api/v1/gate`` and forwards all v3 wire fields - (``chain_id``, ``chain_op``, ``idempotency_key``, ``stream``). - ``check `` is the canonical entry point; ``check_v3`` is kept - as a v3-named alias for callers/tests that already use it. - - 2. ``Transport.track_single`` docstring + ``tests/test_v3_wire_contract.py:: - test_track_single_includes_protocol_header`` body (drift B2): the - docstring described a fictitious wire shape ``{execution_id - actual_cost_cents, api_key_id, cost_source}``. The real backend - ``TrackRequestRaw`` is ``{workflow_id, tokens, cost_cents,...}`` - (built by ``runtime._build_v3_track_payload``) — ``execution_id`` - is replaced by ``reservation_id``, and the SDK always emits - ``cost_cents: 0`` because the backend recomputes the authoritative - cost from tokens + the org's pricing policy (see - ``_WIRE_STRIP_FIELDS`` in runtime.py). ``api_key_id`` is derived - server-side from the request auth, not supplied by the SDK. - Docstring + test body now match the real contract. - - 3. ``Transport.chain_end`` (drift B3): was POSTing to - ``/api/v1/chain/end`` — that endpoint was never registered on - the backend (``backend/src/proxy/http/routes.rs`` has zero - matches). Now POSTs to ``/api/v1/gate`` with ``chain_op: "end"`` - (matches the documented backend contract from - ``backend/src/proxy/http/cancel.rs:39``'s own comment). - - 4. ``Transport.approximate_budget`` (drift M3): was appending - ``?organization_id=`` to the URL. The backend's - ``approximate_budget_handler`` (``backend/src/proxy/http/ - budget.rs:130-145``) resolves the org from the X-API-Key / - Authorization header — it does NOT accept a query parameter. - The method now calls the bare URL. The ``organization_id`` - argument is retained as an accepted-but-unused parameter for - backward compatibility with any external caller that still - passes it (silently no-ops). - -Tests touched (in ``tests/test_v3_wire_contract.py``): - * ``test_check_v3_includes_protocol_header`` — re-mocked against - /api/v1/gate (was /api/v1/check). - * ``test_check_v3_accepts_chain_context`` — re-mocked against - /api/v1/gate (was /api/v1/check). - * ``test_chain_end_includes_protocol_header`` — re-mocked against - /api/v1/gate (was /api/v1/chain/end); added chain_op=end check. - * ``test_chain_end_sends_chain_id_in_body`` — re-mocked against - /api/v1/gate (was /api/v1/chain/end); added chain_op=end check. - * ``test_track_single_includes_protocol_header`` — body now matches - the real wire shape (reservation_id + workflow_id + tokens + - cost_cents:0 + cost_source:"provisional"). - -1037 lib tests pass (no regression).

No on-wire change; backends on 1.0.0 keep working unchanged. - - 1. ``pyproject.toml`` mypy config rewritten from a single - blanket ``ignore_errors = true`` (12 files / 102 errors swallowed) - to per-file ``[[tool.mypy.overrides]]`` blocks — every legacy - module now declares the EXACT error codes it carries, so CI - breaks the moment a NEW code appears in that module rather - than the previous "everything passes" status. ``strict = true`` - is enabled on the 14 modules already clean enough to keep it; - modules still carrying debt opt in via targeted - ``disable_error_code`` lists. Per the comment block at the - top of the overrides section: when a file's count drops to 0, - remove its override row — the table and the debt tracker stay - in lockstep. - - 2. Singleton state split out of ``runtime.py`` into two new - internal modules: - - * ``nullrun._singleton`` — ``NullRunRuntimeMeta`` descriptor - backing the ``_instance`` class attribute (the one and - only canonical instance slot). Module-level ``_runtime`` - PEP 562 ``__getattr__`` proxies in runtime.py / - decorators.py route reads through here so - ``import nullrun; nullrun.runtime`` and - ``from nullrun.runtime import _runtime`` both resolve to - the same instance without the legacy - ``_instance = runtime`` assignment that broke whenever - the metaclass was bypassed (e.g. by ``copy.deepcopy`` - or by tests that constructed ``NullRunRuntime`` directly - without going through ``__init__``). - - * ``nullrun._registry`` — the per-process registry of - runtime capabilities (chain-mode gate cache, LRU - fingerprints, websocket handles). Previously inlined - as module globals in ``runtime.py``; now centralised - so the orchestrator module stays under the strict-mypy - umbrella and external test code can swap or inspect the - registry without monkeypatching the orchestrator. - - 3. ``NullRunRuntime._instance = runtime`` backwards-compat line - retained at the bottom of ``NullRunRuntime.__init__`` so - external callers that read ``NullRunRuntime._instance`` - directly (and there are a handful in the integration tests - shipped by partners) keep working — the new metaclass - descriptor makes the assignment a no-op for the singleton - case but is still semantically a write so legacy reflection - code does not crash. - - 4. ``ruff`` ignore list dropped ``F821`` (undefined name) — the - one site was a typo fixed by the previous ``fix typos`` - commit on this branch. The remaining five (S110 / E501 / - F841 / E402 / F401) are pre-existing and explicitly tracked - in the pyproject comment block for a future cleanup PR. - - 5. ``tests/test_registry.py`` (new, 12 tests) — covers the - registry / singleton contract end-to-end: - ``NullRunRuntimeMeta`` raises on second ``__init__``, - ``reset_for_tests`` clears the registry without touching - the class descriptor, ``_capture_server_minted_*`` context - helpers round-trip through the new module, and the legacy - ``_instance`` read path still returns the live singleton - after the split. - -Tests: - * ``tests/test_registry.py`` — 12 tests for the new modules. - * Existing suite untouched: 1037 lib tests still pass. - -Backends on 1.0.0 keep working unchanged.

The previous loop was - uncancellable — any caller of ``runtime.shutdown()`` while the - thread was mid-sleep blocked on ``thread.join()`` for the full - default 5s ``flush_interval`` before teardown could proceed. - With 1222 tests in the suite and many paths calling - ``shutdown()`` (or its fixture teardowns), that multiplied into - ~10-15 minutes of pure teardown wall-clock per Python in the - matrix. New ``threading.Event`` is set by ``stop()`` before - ``join()`` and cleared by ``start()`` so a restart-after-stop - is clean. Pin contract: ``tests/test_transport.py:: - test_stop_interrupts_flush_sleep`` uses a 30s ``flush_interval`` - and asserts ``stop() < 5s``; pre-fix this took 30s, post-fix - ~0.3s. - - 2. CI workflow cleanup (.github/workflows/ci.yml + - publish.yml + publish-test.yml): - - * ``setup-python`` action now declares ``cache: pip`` with - ``cache-dependency-path: pyproject.toml`` so warm caches - skip the ~60-90s cold ``pip install -e .[dev]`` per matrix - leg. - * ``strategy.fail-fast: true`` on the test matrix so a red - run doesn't burn the remaining Python legs once the first - one fails. - * ``pip install "pytest-xdist>=3.6"`` + ``pytest -n auto`` so - the suite runs across all runner cores. ``xdist`` is also - added to ``[project.optional-dependencies.dev]`` so local - ``pip install -e .[dev]`` brings it in by default. - * ``coverage`` job also gets ``-n auto`` (single Python leg, - 3.12, is unchanged). - - 3. ``pyproject.toml``: dropped the global ``-q`` from - ``addopts`` so CI logs surface the full ``PASSED`` line per - test. ``--tb=short`` keeps tracebacks compact. ``-n auto`` - stays in the workflow (not in ``addopts``) so a developer - running ``pytest tests/test_x.py`` locally still gets a single - process — the worker pool is only worth it on the full - suite. - -No public API change.

Verified against `backend/src/proxy/http/protocol.rs`, `backend/src/proxy/middleware/auth.rs`, and CLAUDE.md §5 / §13 — not against comments or documentation. No SDK_MIN_VERSION bump. No on-wire change (backend already shipped the matching wire shape; this SDK release closes the consumer side). ### Fixed -- **Capabilities probe route** — `nullrun.capabilities.CAPABILITIES_PATH` was `"/health"` (a generic liveness endpoint) instead of the canonical `"/api/v1/capabilities"`. Pre-fix, every `init()` probe returned `None` and `is_v3_ready()` was always `False`, so every v3 capability flag (`server_minted_execution_id` / `per_execution_reservations` / `enforcement_modes_soft` / `heartbeat_time_based`) was a runtime no-op — even when the backend was v3-ready. The new probe URL matches `backend/src/proxy/http/protocol.rs::capabilities_handler` (canonical wire contract since 2025-04). -- **API_KEY_* error code granularity (v3.38 backend split)** — backend v3.38 split the `API_KEY_REVOKED` bucket into five distinct wire codes: `API_KEY_EXPIRED` / `API_KEY_DISABLED` / `API_KEY_INVALID` / `API_KEY_MISSING` / `API_KEY_MALFORMED` (mirrors CLAUDE.md §13 vocabulary). Pre-fix, only `API_KEY_REVOKED` was mapped in `_V3_ERROR_CODE_MAP`; the other five silently fell through to the generic HTTP-status fallback at `transport.py:~2616` and never surfaced as `NullRunAuthError`, losing both the exception class and the diagnostic `wire_code`. The map now covers all six wire codes. The envelope parser filters unknown `details` keys to a known kwargs set (`{error_code, user_action, retryable, docs_url, cause}`) and parks extras on `self.details` — the pre-fix behaviour was to forward every detail as a kwarg and raise `TypeError` on the first unknown key (the regression appeared once v3.38 EXPIRED responses started emitting `expires_at` in details). -- **`NullRunAuthError.wire_code`** — the exception class gains a `wire_code: str | None = None` constructor kwarg that defaults to `"API_KEY_REVOKED"` for backwards compat. Mirrors the existing `NullRunChainError.backend_code` pattern at `breaker/exceptions.py:448`.

Sub-agent SDKs stamp the field manually from a caller-supplied UUID; auto-injection from a "current execution_id" contextvar is deferred (v0 is intentionally caller-owned). -- **`execution_graph` capability flag** — `parse_capabilities` reads the new `execution_graph: bool` from `/api/v1/capabilities` (nested under `capabilities:` with top-level fallback for pre-1.0.0 backends). `ServerCapabilities.execution_graph` exposes the flag so SDKs can probe whether the deployment supports sub-agent lineage before sending the field.

All OpenAI v1.0+ traffic is now tracked via the httpx - transport hook in `nullrun.instrumentation.auto`. -- **`DecisionHistoryRecorder.replay_locally` / `replay_event` / - `replay_from_file` deleted.** They called `runtime.track` (which - hits the backend) despite the docstring claiming "local-only". - The honest-scope local recorder surface (`start_recording`, - `stop_recording`, `record_event`, `estimate_cost`, - `RecordingSession.to_dict` / `from_dict`) is preserved. -- **`observability.TenantFilter` no longer writes the deprecated - `org_id` field** — only the canonical `organization_id` and - `api_key_id` remain.

Pre-fix the - PAN at position 0 was forwarded as-is into ``/execute`` and landed - in the audit log. - -- **P0-3 (OOM): streaming response memory cap.** Sync and async - httpx transports now use bounded chunked reads capped at - ``MAX_RESPONSE_BYTES`` (16 MiB by default; ``NULLRUN_MAX_RESPONSE_BYTES`` - env var to override). When the cap is exceeded, tracking is skipped - and ``_coverage_streaming_skipped`` is incremented so the dashboard - sees which hosts are producing oversized responses. Pre-fix - ``response.read()`` / ``await response.aread()`` buffered the entire - response body in memory — a 16+ MB allocation per streaming LLM - call under load. - -- **P0-4 (cost-audit): drop-newest on buffer overflow.** The CB-OPEN - re-queue path in ``Transport._do_flush_locked`` now drops the - NEWEST non-critical events instead of the oldest. The oldest - events (start-of-incident, start-of-billing-period) are exactly - what a billing investigator needs to reconstruct — losing them - silently broke monthly rollups. Control-plane events - (``state_change`` / ``kill_received`` / ``policy_invalidated`` / - ``key_rotated``) are preserved regardless of position so the - dashboard's KILL switch continues to land even under sustained - backend outage. - -- **P0-6 + P3-3 (security): redact-before-truncate.** ``_safe_repr`` - now runs ``_strip_details_balanced`` on the FULL repr before - truncating to ``max_len=50``. Pre-fix the truncate ran first, and - if ``details={...}`` lived past position 50 in the original repr - (common for httpx.HTTPError with a long URL), the redact pass - saw nothing on the truncated slice and the raw payload leaked - into ``span_end`` audit events. - -- **S-8 / P2-4: ``agent_id`` is now a real UUID with dashes.** - ``agent()`` context manager emits ``str(uuid.uuid4())`` (e.g. - ``95ca7c0b-8334-478a-af23-2788803ef3b8``) for auto-generated ids. - Pre-fix the format was ``f"agent-{uuid.uuid4().hex}"`` — 32 hex - chars with no dashes; backend UUID-typed columns silently - dropped these to NULL on insert. User-supplied names are still - preserved verbatim. - -- **S-9: LRU cap on ``NullRunCallback._active_runs``** (4096 entries, - FIFO eviction with WARN log). Pre-fix this dict grew unbounded - when ``on_chain_end`` did not fire (errors in the chain body - short-circuited the end hook for some LangChain versions), - leaking memory in long-running services. - -- **S-10: WebSocket reconnect max-attempts cap** (10 consecutive - failures). Pre-fix the loop was unbounded (``while not - self._closed:``) and leaked the WS thread forever when the backend - was permanently down. After the cap the SDK falls back to - HTTP-poll for control-plane state delivery. - -- **P2-1: ``_coverage_seen`` now bumps in the httpx path.** - Pre-fix the counter was only incremented in the ``requests`` - path (``auto_requests.py:185``), so the dashboard's coverage - view was empty for the dominant httpx traffic (every OpenAI / - Anthropic / Gemini / Mistral / Cohere call). Now both sync and - async httpx ``_emit`` bump the counter. - -- **P3-2: webhook delivery uses exponential backoff** (cap 30s). - Pre-fix the schedule was linear (``0.5 * (attempt + 1)``); under - sustained outage this produced a tight retry storm on the dead - endpoint — each KILL/PAUSE spawned its own delivery thread. - Post-fix the schedule is ``0.5 * 2**attempt`` capped at 30s: - 0.5s, 1.0s, 2.0s, 4.0s, 8.0s, 16.0s, 30.0s. - -### Tests - -Added regression tests for every item above (57 new tests across 9 -new test files: ``test_agent_id_uuid.py``, ``test_args_pii_masked.py``, -``test_streaming_oom_cap.py``, ``test_lru_active_runs.py``, -``test_reconnect_cap.py``, ``test_coverage_seen_httpx.py``, -``test_webhook_backoff.py``, ``test_redact.py``; existing -``test_buffer_invariants.py`` extended with drop-newest + critical-event -preservation cases). - -### Legacy - -- **SDK silent runtime fallback removed** (FIX-4): `_get_or_create_runtime` - in `nullrun.decorators` no longer wraps `NullRunRuntime.get_instance()` - in a `try/except Exception` that rebuilds a no-arg `NullRunRuntime()`. - In 0.3.0 (T3-S2) the no-arg constructor requires `api_key` and raises - `NullRunAuthenticationError` — so the fallback swallowed the auth - error from `get_instance()` only to crash with the same error from - the fallback path itself.

Drop WIP [0.10.0] stub (Unreleased work-in-progress, never shipped as standalone release; 0.11.0 became the canonical v3.0 cut). - Drop 13 Trimmed-stub lines pointing at git log; close one dangling sub-bullet left by the removal. - Reorder release blocks in strict descending version order: was 0.9.1 -> 0.11.0 -> 0.9.0 (lower: 0.3.1 -> 0.5.2 -> 0.4.0); now 0.11.0 -> 0.9.1 -> 0.9.0 (lower: 0.5.2 -> 0.4.0 -> 0.3.1). Net: -29 lines, semver -> date sort invariant holds. #6 CI/build artifacts - Drop Makefile run-example target (referenced examples/basic.py; examples/ was deleted in 0.3.1 alongside the gRPC transport). Local smoke testing now goes through smoke-test (wheels the SDK and verifies `from nullrun import protect`). - Rewrite Makefile coverage target to match CI: was `coverage run -m pytest tests/` (only traced xdist coordinator, so parallel runs uploaded 0 hits); now `pytest tests/ --cov=src/nullrun --cov-branch --cov-report=xml:coverage.xml --cov-report=term`, matching .github/workflows/ci.yml:82. - clean target now also removes coverage.xml. #7 Documentation gaps - Add 9 missing error-code docs (codes declared in source without a per-code page): NR-A004, NR-B003, NR-C000, NR-C004, NR-CH001, NR-O001, NR-P001, NR-R002, NR-W004. - Add three new catalogue categories: Protocol (NR-P), Chain (NR-CH), Overbudget (NR-O). README.md catalogue now covers all 23 documented codes. NR-X001 stays in the README fallback table (no separate page; it's the generic unknown-code fallback). Verified via cross-check: all source-referenced codes are documented. Tests: 23/23 exception hierarchy pass; full suite remains green. --- CHANGELOG.md | 165 +++++++++++++++++----------------------- Makefile | 23 +++--- docs/errors/NR-A004.md | 70 +++++++++++++++++ docs/errors/NR-B003.md | 66 ++++++++++++++++ docs/errors/NR-C000.md | 31 ++++++++ docs/errors/NR-C004.md | 55 ++++++++++++++ docs/errors/NR-CH001.md | 71 +++++++++++++++++ docs/errors/NR-O001.md | 78 +++++++++++++++++++ docs/errors/NR-P001.md | 66 ++++++++++++++++ docs/errors/NR-R002.md | 67 ++++++++++++++++ docs/errors/NR-W004.md | 68 +++++++++++++++++ docs/errors/README.md | 35 ++++++++- 12 files changed, 685 insertions(+), 110 deletions(-) create mode 100644 docs/errors/NR-A004.md create mode 100644 docs/errors/NR-B003.md create mode 100644 docs/errors/NR-C000.md create mode 100644 docs/errors/NR-C004.md create mode 100644 docs/errors/NR-CH001.md create mode 100644 docs/errors/NR-O001.md create mode 100644 docs/errors/NR-P001.md create mode 100644 docs/errors/NR-R002.md create mode 100644 docs/errors/NR-W004.md diff --git a/CHANGELOG.md b/CHANGELOG.md index bd506e1..5a78ce8 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -264,43 +264,6 @@ Server-minted execution_id default ON.

The canonical dispatcher at transport._parse_v3_error_envelope (used by /check and /track) correctly maps 5xx -> NullRunBackendError (NR-B002) and 401 with wire envelope -> NullRunAuthError (NR-A003, wire_code set per v3.38). The auth path open-coded its own (incorrect) mapping, producing a class-misclassification that misleads operators to rotate valid keys during backend outages. Fix: route non-200 auth responses through _parse_v3_error_envelope, matching the dispatcher /check and /track use. Lazy import inside the else arm keeps runtime.py's top-level import graph stable. Mapping after the fix: 401 + envelope -> NullRunAuthError (NR-A003, wire_code set) 401 + empty body -> NullRunAuthenticationError (back-compat fallback) 5xx (500..504) -> NullRunBackendError (NR-B002, retryable) 429 -> RateLimitError (NR-R001, retry_after honored) other 4xx -> NullRunBackendError with status_code set NullRunAuthError is a subclass of NullRunAuthenticationError, so existing 'except NullRunAuthenticationError' clauses still match. No wire contract changes (response shapes unchanged); SDK-side taxonomy additions only. Tests: 5 new regression tests in tests/test_runtime.py pin the per-status mapping. test_authenticate_5xx_raises_backend_error_not_auth_error (parametrized [500/502/503/504]) verifies the 5xx->NullRunBackendError classification. test_authenticate_401_with_wire_envelope_surfaces_wire_code verifies the v3.38 wire_code contract for /auth/verify. Verification: pytest tests/test_runtime.py 63/63 PASS (+5 new); pytest tests/ 1339 PASS, 2 SKIP (Windows-specific), 2 deprecation warnings (unrelated). Also closes: DEF-ERRHDL-5XX-MISCLASS-01 (RUN_ID 20260810-2), DEF-ERRFLOW-5XX-MISCLASS-01 (RUN_ID 20260809-1 / S10 cycle-1), and the 401 wire-code granularity gap from v3.38 in the auth path. Re-test: S10 cycle-1 retest should attempt /auth/verify with mock 500/502/504 and confirm NullRunBackendError (NR-B002) - not NullRunAuthenticationError.

Keeping ``extractor.py`` as a pure helper avoids +the ``inspect.signature()`` cost on every sensitive call (the +binding result is cached after first extraction via Python's +``lru_cache``-friendly design) and makes the unit-discriminator +test matrix cheap to write without instantiating the full +``NullRunRuntime``. + +For the production flow, ``runtime.execute(...)`` reads the +extractor from the function's ``_nullrun_extractor`` attribute +(which ``@sensitive(impact=money_outflow(...))`` sets) and calls +``impact_for(...)`` automatically. + +## Why ``units`` is explicit, not a type discriminator + +The previous review explicitly rejected the +``int = minor, Decimal = major`` shortcut because the unit +semantics of a function argument should not flip silently when +the function signature is refactored. Concretely: + + @nullrun.sensitive(impact=nullrun.money_outflow(argument="amount")) + def refund(amount: int) -> ... # 50 = 50 cents (minor units) + def refund(amount: Decimal) -> ... # 50 = $50.00 (5000 cents) + +If ``units`` were implicit-from-type, renaming ``amount``'s +annotation from ``int`` to ``Decimal`` would silently change the +operator-facing rule from "$0.50" to "$50.00". The explicit +``units="major" | units="minor"`` argument in the decorator +fixes the unit semantics at the call site so a future +signature refactor does not flip the meaning. + +## Float is rejected outright + +``Decimal`` exists precisely so that money code does not have +to deal with binary-floating-point surprises (``0.1 + 0.2 != +0.3`` in IEEE-754). The extractor therefore refuses ``float`` +values at the input level. The error includes a pointer to +the right alternative (``Decimal`` for major, ``int`` for minor) +so the operator can fix the call site without guessing. + +## Major-unit precision is validated, never rounded + +The first version of this module used banker's rounding +(``ROUND_HALF_EVEN``) to convert ``Decimal("50.99")`` to +``5099`` minor units. That decision was rejected in review: +banker's rounding silently drops sub-cent precision +(``Decimal("50.005")`` becomes ``5000`` minor units), which +is the exact bug class the explicit ``units`` discriminator +is designed to prevent. The current contract validates the +precision of the ``Decimal`` against the ISO-4217 minor-unit +exponent for the currency and raises ``InvalidMoneyPrecisionError`` +if the caller supplied more precision than the currency +supports. The caller can explicitly truncate with +``value.quantize(Decimal('1E-N'))`` to opt in to rounding; the +SDK never rounds silently. + +## Sign is validated + +A negative amount for either ``money_outflow`` (debit) or +``money_inflow`` (credit) is semantically incoherent. The +review pointed out that ``{"direction":"outflow", +"amount_minor":-5000}`` would silently fall through every +``op=gt`` predicate because ``-5000 > 5000`` is always False, +and the operator would never see a block. The current contract +rejects negative amounts with ``InvalidMoneyAmountError`` so the +``@protect`` wrapper can fail-CLOSED on the call site. If a +future variant needs negative amounts (e.g. refunds as negative +outflows) it can opt in via a future ``units="signed"`` +discriminator. + +## Overflow is bounded + +``i64`` can hold up to ``2**63 - 1 = 9_223_372_036_854_775_807`` +minor units (about $9.2 \u00d7 10\u00b9\u2076 for USD). The extractor checks +the converted value against this limit and raises +``InvalidMoneyAmountError`` if it would overflow. The check +uses ``int`` post-conversion so the operator sees the +offending amount, not just "too large". + +## Business cap is bounded + +The wire-format ``i64`` limit is a few hundred quadrillion +dollars, which is well above any sensible per-call debit. The +business cap (``_BUSINESS_CAP_MINOR`` table) is a much smaller +per-currency limit chosen so that any amount above the cap +goes through a separate risk path rather than being treated +as a normal call. The cap is policy, not correctness: a $1M +USD debit is technically valid on the wire, but for an agent +running a refund tool it almost certainly warrants a human +review. The cap is enforced as ``InvalidMoneyAmountError(reason="excessive")`` +with a clear "above the per-call business cap" message; the +``@protect`` wrapper upgrades the error to fail-CLOSED. + +## Float and ``bool`` are rejected + +``float`` is rejected because IEEE-754 surprises are the entire +reason ``Decimal`` exists. ``bool`` is rejected because ``bool`` +is a subclass of ``int`` in Python; without the explicit check, +``refund(amount=True)`` would silently treat ``True`` as +``1`` cent. + +## Currency is validated (whitelist + case) + +ISO-4217 minor-unit exponent lookup covers a small set of +codes by design. The ``normalize_currency`` helper rejects any +input that is not a 3-letter uppercase ISO-4217 code (e.g. +``"usd"``, ``"Usd"``, ``"USDX"``, ``""`` raise +``InvalidCurrencyError``). The SDK does NOT silently +upper-case the input because: + +- it would hide typos (``"usd"`` vs ``"USD"`` vs ``"Usd"`` + would all normalize to ``"USD"``, masking a typo in the + call site); +- ISO-4217 is a closed set of 3-letter uppercase codes, + anything else is wrong by definition; +- the error message names the offending input so the operator + can fix the call site. + +The whitelist is consulted by ``currency_minor_digits`` and +``business_cap_minor``; unknown codes are rejected with +``InvalidCurrencyError`` instead of falling back to a default. +This closes the conservative-fallback gap from the previous +hardening pass (``UNKNOWN`` was allowed but the operator +might never notice the typo). + +## Currency case rejection is enforced at construction time + +The ``MoneyImpactExtractor.__init__`` validates the currency +via ``normalize_currency``.

Removing them = silent coverage regression. Files restored (all from master HEAD): - tests/test_protect_branches.py (564 lines) — branch coverage for _safe_args / _strip_details_balanced / _enforce_sensitive_tool - tests/test_runtime_branches.py (517 lines) — less-trodden error paths in runtime.py. Removed 2 tests (test_start_recording_returns_* and test_stop_recording_returns_none) because a666624 P1 also intentionally removed the deprecated no-op stubs from runtime.py (replaced by direct return-value gates per the commit message). Restoring the tests without the methods would create dead tests. - tests/test_transport_branches.py (647 lines) — branch coverage gaps in transport.py Verification: pytest tests/ → 1462 passed, 6 skipped, 0 failed. The 6 skipped are pre-existing environment markers. Pairs with commit 700b0af (revert of ea77e21 Cyrillic scrub). Together they close the over-aggressive parts of the cleanup sprint without disturbing the valid P1 dead-code removal, P4 CHANGELOG dedup, and v3.38/server-minted test consolidations. --- tests/test_protect_branches.py | 564 +++++++++++++++++++++++++++ tests/test_runtime_branches.py | 504 ++++++++++++++++++++++++ tests/test_transport_branches.py | 647 +++++++++++++++++++++++++++++++ 3 files changed, 1715 insertions(+) create mode 100644 tests/test_protect_branches.py create mode 100644 tests/test_runtime_branches.py create mode 100644 tests/test_transport_branches.py diff --git a/tests/test_protect_branches.py b/tests/test_protect_branches.py new file mode 100644 index 0000000..5cc0962 --- /dev/null +++ b/tests/test_protect_branches.py @@ -0,0 +1,564 @@ +""" +Additional tests for ``nullrun.decorators`` — branch coverage for the +``_safe_args`` / ``_strip_details_balanced`` / ``_enforce_sensitive_tool`` +helpers, the fail-CLOSED / fail-OPEN contract, the KILL→BlockedException +unification, and the ``@protect `` paren-form. +""" + +from __future__ import annotations + +import os +from types import SimpleNamespace +from unittest.mock import MagicMock + +import pytest + +from nullrun.breaker.exceptions import ( + NullRunBlockedException, + NullRunTransportError, + TransportErrorSource, + WorkflowKilledInterrupt, + WorkflowPausedException, +) +from nullrun.decorators import ( + SENSITIVE_ARG_KEYS, + _enforce_sensitive_tool, + _safe_args, + _safe_error_str, + _safe_kwargs, + _safe_repr, + _strip_details_balanced, + protect, + sensitive, +) +from nullrun.runtime import NullRunRuntime + + +@pytest.fixture +def test_runtime(monkeypatch, tmp_path): + """Provide a runtime in test mode so get_runtime returns without + authenticating against a real server. + + Replays any WAL left over from previous test runs in a + tmp_path-scoped WAL file so the constructor's + ``_replay_from_wal`` never reads ``~/.nullrun/sdk.wal`` and + flushes real on-disk events to a live API.

Patch release; partial revert of two sprint-5 cleanup commits whose scope exceeded what the codebase actually supported. This release closes the over-aggressive parts of the cleanup sprint without disturbing the valid P1 dead-code removal, P4 CHANGELOG dedup, and v3.38/server-minted test consolidations. - Revert ea77e21 (Cyrillic scrub + docstring trim): restored the 30-line 'partially wrong' block in src/nullrun/runtime.py (codifies CLAUDE.md \u00a74 fail-CLOSED rules for SDK transport vs backend enforcement), restored 'Разрыв 2' / 'Разрыв 1c' in CHANGELOG.md (user-coined Russian technical nomenclature), and restored tests/test_real_e2e_observation.py (321 lines, the only real-socket integration test). - Cherry-pick restore 3 branch-coverage files deleted by a666624 P2: tests/test_protect_branches.py (564), tests/test_runtime_branches.py (515; minus 2 tests for deprecated start_recording/stop_recording no-op stubs that a666624 P1 also intentionally removed), and tests/test_transport_branches.py (647). These files explicitly documented their purpose as covering 'gaps' and 'less-trodden error paths' that the mainline tests skip. Verification: pytest tests/ -> 1462 passed, 6 skipped, 0 failed. Pairs with commits 700b0af (revert ea77e21) and 2df6b3a (restore branch-coverage tests) on cleanup/p1p2-dead-code-tests. Compatibility: No SDK_MIN_VERSION bump.

Если backend недоступен, бюджет не блокирует агента` is **partially wrong**. The restored block makes the explicit split: SDK-side transport failure (network timeout, 5xx, breaker open) → fail-OPEN on the *check* path so a dead backend doesn't freeze the user's agent loop; backend-side enforcement failure (`BUDGET_REDIS_UNAVAILABLE` → 402, `RATE_LIMIT_REDIS_UNAVAILABLE` → 503) → fail-CLOSED wire response (the SDK does NOT silently fall-OPEN on a wire 4xx/5xx that names an enforcement failure).

The five `Transport.audit_*` methods that previously returned raw dicts now accept `organization_id` as a positional parameter (organisation lives on the runtime, not the transport); callers that previously wrote `transport.audit_log(org)` continue to work — the new proxy at `runtime.audit.list()` is the recommended path going forward. + +### Added + +- **`nullrun.audit` module** — frozen dataclasses for the ADR-009 read surface: `AuditEntry`, `AuditLogMeta`, `AuditLogPage`, `AuditQuery`, `AuditVerifyResult`, `AuditExportJob`, `AuditExportStatus`.
