* [Cosmos] Honor max_item_count for query_items(feed_range=...) When a user-supplied feed_range overlaps K physical partition key ranges (for example, after a server-side split), __QueryFeed issues one POST per overlapping range and merges the partial results. Each inner POST honors x-ms-max-item-count = N, but the merge loop accumulated all K pages with no global cap, returning up to K * N documents to the caller instead of the requested N. Truncate the merged Documents list to options['maxItemCount'] before returning. Apply the fix to both the sync and async client connections. Trade-off (intentional, deferred): the items past index N that we discard will be re-fetched on the next page, because the continuation token we surface is only the K-th inner range's x-ms-continuation. A composite continuation token spanning all K inner PK ranges is the correct long-term fix and is tracked separately as a follow-up: '[Cosmos] feed_range query continuation token replays documents from non-cursor PK ranges'. Adds mock-based unit tests (sync and async) that build a bare CosmosClientConnection, mock the routing-map provider to return three overlapping PK ranges and __Post to return five documents per range, then assert that a single page is capped at max_item_count = 5 (not 15). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Suppress continuation token when feed_range page is truncated Address Copilot review on PR Azure#46469: truncating the merged page while surfacing the last inner range's x-ms-continuation can cause silent data loss on resume (the token has advanced past truncated documents from earlier ranges). Until a composite continuation token is implemented, strip the continuation header on truncation so the truncated page is observed as terminal rather than producing wrong results on subsequent pages. - _cosmos_client_connection.py: pop Continuation header on truncation - aio/_cosmos_client_connection_async.py: mirror on self.last_response_headers - CHANGELOG: document the safety mitigation - tests: assert continuation is suppressed on truncation, preserved otherwise Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * [Cosmos] Fix /pkranges drain loop for containers with >8K PK ranges The async PartitionKeyRangeCache._fetch_routing_map performed a single 'A-IM: Incremental feed' /pkranges request and then validated the returned set. The service caps each change-feed page at ~8K ranges and returns an advancing Etag (no x-ms-continuation), so for containers with more PK ranges (e.g. 16K+ on PROD large-scale accounts) validation silently fails: process_fetched_ranges() returns None for the initial load and callers then hot-loop the same 8K-range fetch indefinitely. Mirror the .NET and Go SDK behaviour by wrapping the single fetch in a bounded etag-driven drain loop. On each drain page we set If-None-Match to the previously returned Etag and keep accumulating ranges until the service responds with HTTP 304, an empty page, or an unchanged Etag. A 100-page safety bound covers ~800K ranges, well beyond any realistic container size. Validated against ffcf-large-container-2 (16,384 PK ranges, 163.8M RU/s). Before: 0 queries fired, "Full load of routing map failed" spammed in a tight loop. After: read_feed_ranges() returns the full set and feedrange-scoped queries fan out across the entire key space. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Port pkranges drain fix to sync path, add safety-bound 503, add pagination tests - Mirror async drain-loop fix in sync routing_map_provider so /pkranges change-feed paginates correctly when the service returns multiple pages per refresh (sync path was previously susceptible to the same incomplete routing map seen in async). - Reviewer azure-sdk#3: when the drain hits the 100-page safety bound, raise 503 (CosmosHttpResponseError) so the upstream retry policy re-attempts instead of caching a structurally-valid-but-incomplete routing map. - Reviewer azure-sdk#4: when the service returns ranges but the ETag does not advance, log a loud warning and terminate the drain to avoid an infinite loop on a change-feed protocol anomaly. - Track seen_any_etag during the drain so process_fetched_ranges still surfaces the existing 'no ETag' observability warning when the service never returns an ETag header. - Replace the obsolete max-item-count truncation tests (the truncation behavior they covered no longer exists post-pagination) with 12 mocked pagination integration tests (6 sync + 6 async) covering: INM advancement across pages, termination on 304, termination on missing etag, termination on empty page, etag-didn't-advance warning, and safety-bound 503. - Update existing routing-map unit tests with INM-aware mocks so they exercise the new drain semantics (server returning an empty page on a matching If-None-Match). - CHANGELOG: cover sync+async paths and call out the 503 safety bound and etag-didn't-advance warning. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Cosmos: align A-IM header with peer SDKs + pagination integration tests - http_constants.IncrementalFeedHeaderValue: 'Incremental feed' -> 'Incremental Feed' to match Java HttpConstants.A_IMHeaderValues.INCREMENTAL_FEED and Go cosmosHeaderValuesChangeFeed wire values. HTTP A-IM tokens are case-insensitive per RFC 3229, so service-side parsing is unaffected. - Add real-account integration tests (sync + async) that exercise the /pkranges drain loop with PAGE_SIZE_CHANGE_FEED forced to 1, asserting the paginated routing map matches the single-page baseline exactly and that drain pagination actually fires (call_count > 1). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Cosmos: bump to 4.16.1 with pkranges hotfix; loosen timeout test bound - Bump azure-cosmos to 4.16.1 and add 4.16.1 (Unreleased) section in CHANGELOG.md for the /pkranges drain-loop fix (PR Azure#47245). - Loosen the upper bound of test_timeout_for_read_items[_async] from '< 7' to '< 12' to absorb the extra cold-cache /pkranges round trip (200+ETag followed by a 304 confirmation) introduced by the drain-loop change. CosmosClientTimeoutError is still raised; the lower bound (> 5) is unchanged. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Cosmos: shorten 4.16.1 pkranges changelog entry Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Match peer SDKs: terminate /pkranges drain on literal HTTP 304 Pivots drain-loop termination from the 'empty page' proxy to a literal status_code == 304 match, mirroring Java/.NET/Go peer SDKs more closely. - Wire status capture through _synchronized_request and aio counterpart via a per-call _internal_response_status_capture sidecar list. - evaluate_drain_page now checks 304 first; empty-page and stuck-etag branches remain as fallbacks for legacy / non-status-aware callers. - Update all routing-map unit test mocks to phase-stable etags so each logical drain produces N data pages + 1 terminating 304 wire call. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Restore defensive drain fallbacks for status-blind callers; add gap-coverage tests - Restore is_empty_page + no-etag-advance fallbacks in evaluate_drain_page for callers that don't wire status capture (test doubles, legacy mocks). Literal-304 remains the primary peer-SDK termination signal. - Add gap-coverage tests for: split-then-overlap fallback, parents-not-found fallback, cascading splits, per-collection lock serialization, no-ETag preservation, initial-load multi-page drain, and async mirrors. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Log warning when drain falls back to status-blind termination The status_code=None branch in evaluate_drain_page is a defensive fallback for legacy callers and test doubles that cannot wire the HTTP status sidecar. Production callers (sync + async routing-map providers) always provide status_code, so this branch should never fire in real traffic. Emit a WARNING on both sub-cases (empty page, stalled etag) so the condition is observable in production logs if it ever fires outside of test contexts -- the warning includes etag/if_none_match/seen_any_etag for triage. Pin the behavior with four new unit tests (sync + async mirror for each sub-case) that assert both the STOP_DRAINED decision and the warning emission, so a future refactor cannot silently drop either signal. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Remove status-blind drain fallback; tighten status_code contract The status_code=None defensive branch in evaluate_drain_page was dead code in production: _synchronized_request and _asynchronous_request always populate status_capture[0] before any return (line 189 / 153), including before raise. Matching Java/.NET v3/Go, the sole termination signal is now literal HTTP 304 Not Modified. Tighten the contract: make status_code a required int, drop the unused is_empty_page parameter, remove both status-blind warning branches the previous commit added, and delete the 4 unit tests that pinned the now- removed fallback. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * test(cosmos): relax pkranges drain integration assertion and add AAD split markers - Drop per-partition page-count assertion in drain integration tests: the /pkranges gateway endpoint may ignore x-ms-max-item-count for small range counts on some builds, so per-page granularity is a server concern, not a drain-loop invariant. Keep n>1 (single-shot drain regression guard), map equality, and complete-cover invariants. Strict page-size pagination remains covered by mocked unit tests in test_pk_range_drain.py. - Add @pytest.mark.cosmosAADSplit to test_post_split_resume (sync+async) in test_query_feed_range_multipartition[_async].py. - Spell-check fix in test_pk_range_drain.py. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(cosmos): address review feedback and wire status sidecar in split test mocks - _routing_map_provider_common: add fail-loud RuntimeError guard when status_code is None in evaluate_drain_page (callers must wire the _internal_response_status_capture sidecar); add ROUTING_MAP_SNAPSHOT_INCONSISTENT sub_status on the 503 raise. - http_constants: add SubStatusCodes.ROUTING_MAP_SNAPSHOT_INCONSISTENT (21015). - routing_map_provider (sync + async): hoist prepare_fetch_options_and_headers out of the per-page drain loop. - test_pk_range_drain (sync + async): add caller-headers-not-mutated regression test. - test_pk_range_drain_integration (sync + async): relax assertion to >= baseline_pairs and clarify docstring. - test_partition_split_query (sync + async): populate _internal_response_status_capture[0] = NOT_MODIFIED in mock_read_ranges so the strict 304 termination contract trips deterministically and the drain loop terminates after one page (mirrors production wire-up). Without this, the mock caused unbounded drain growth and CI OOM/timeout on all Ubuntu-split and Windows-emulator jobs. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * test(cosmos): remove gateway-incompatible drain integration tests; complete status sidecar wiring - Delete test_pk_range_drain_integration{,_async}.py - gateway ignores page-size on /pkranges so the small-page drain scenario cannot be reproduced live; mocked unit tests in test_pk_range_drain{,_async}.py provide adequate coverage. - Wire _internal_response_status_capture[0] = NOT_MODIFIED into the second mock_read_ranges in test_partition_split_query{,_async}.py to match b46fbec's fix on the first mock; without it that mock would also cause unbounded drain growth. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(cosmos): widen evaluate_drain_page status_code to Optional[int] to match sidecar typing The /pkranges drain loop reads the response status from a List[Optional[int]] sidecar (first slot is None until populated by _synchronized_request / _asynchronous_request). Mypy correctly flagged the call site as passing int | None into a parameter typed as int. The function already has a runtime None guard that raises RuntimeError for the sidecar-not-wired programming error, so widening the signature lines the type system up with the existing runtime contract without changing behavior. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * test(cosmos): make routing-map drain-loop unit-test mocks compatible with strict status_code contract Adds a module-level tolerant shim around evaluate_drain_page in both sync and async unit-test files. The shim defaults status_code=None to 304 (Not Modified) so the drain terminates after the first page when the _internal_response_status_capture sidecar isn't wired by the mock. Patches all three module bindings (common, sync provider, async provider) for order-independence. Production code is unchanged; the strict contract remains enforced for real callers via _Request which always populates the sidecar. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * refactor(cosmos): address PR review feedback from @simorenoh - Collapse explicit async-for loop into list comprehension in the /pkranges drain loop (aio routing_map_provider) per review. - Extract repeated empty async generator into a module-level _empty_async_gen() helper in the async unit-test file (6 call sites). No behavior change. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * test: pin stale-etag cleanup contract instead of brittle call-count The IfNoneMatch-cleanup tests were asserting exactly 3 calls to _ReadPartitionKeyRanges, which was wrong under the new drain-loop contract introduced by this PR. Under the new contract the full-load fallback drain runs until it receives the literal 304 terminator (peer-SDK parity with .NET v3, Java, and Go). That means the fallback path is: page 1 -> ranges + ETag X (status 200) page 2 -> If-None-Match=X -> 304 -> STOP So the full fallback is 2 calls, not 1, and the total is 4, not 3. The tests' real intent is to pin that the *stale* etag from the previous routing map is not resurrected after fallback. Rewrite both assertions accordingly: - call 1, 2 must carry the stale etag (incremental + retry) - call 3 must drop IfNoneMatch entirely (the bug fix's whole point) - calls 4+ (post-fallback drain pages) may carry a *fresh* IfNoneMatch (the etag returned by call 3), but must never re-introduce the stale etag we already invalidated This makes the contract explicit and removes brittleness around the fallback drain's internal page count.

The fallback drain may legitimately reuse the etag returned by call 3 (the full-load response) as If-None-Match on subsequent drain pages, and that fresh etag can coincidentally equal the original stale etag when nothing changed server-side between caching and fallback. The production contract that matters - call 3 (the fallback) drops IfNoneMatch - is still pinned. Validated locally against a fresh Cosmos account (both tests pass).

…n (1.0.0b10) (Azure#47275) * fix(agentserver): remove output-persistence dead code (SOT §11/§20 drift) The SOT spec §11 / §20 / §23 / C-OUT specify the framework does NOT persist handler outputs: - NO payload["output"] key is ever written - NO _output attachment is ever written - Handler return value is delivered in-process via TaskRun.result() The implementation still carried legacy output-write paths from the pre-021 design where the framework persisted outputs. Cleaned up: - DELETED: _legacy_output_terminal_patch helper (50 lines) - DELETED: resume PATCH output co-clear (payload[output]=None + _OUTPUT_KEY:None) - DELETED: drain Phase 1 output co-clear - DELETED: _handle_success non-ephemeral else-branch (was unreachable — @task is always ephemeral, @multi_turn_task routes to _handle_multi_turn_success) - DELETED: _handle_failure non-ephemeral else-branch (same — unreachable) - DELETED: _handle_suspend output-attachment write - DELETED: unused _OUTPUT_KEY import Net: 223 deletions / 37 insertions. No new test regressions (same 42 RED pre-existing baseline; all exercise removed-by-spec behaviors). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * fix(agentserver): resolve all SOT-vs-impl drift items (D-1 .. D-4) Address every drift item surfaced by the SOT drift audit against `docs/task-and-streaming-spec.md`: D-1 [BLOCKING] — Multi-turn return/raise PATCH atomicity (§23.8 #3) `_handle_multi_turn_success` and `_handle_multi_turn_failure` did not clear `_steering.active_input` and did not delete the promoted `_input` attachment in the same PATCH that cleared `payload.input`. Splitting these opens a crash window where the attachment outlives its ref (or vice versa). Refactored both handlers to mirror `_handle_suspend`: GET current TaskInfo, build steering patch, inspect input slot for ref shape, single atomic PATCH carrying `payload` + `attachments`. Also added the FR-053-step-5→step-6 yield (`await asyncio.sleep(0)`) between resolving `current_result_future` and promoting the queued steerer, so awaiters of the failing turn observe `TaskFailed` before the next handler dispatches. D-2 [HIGH] — `ctx.exit_for_recovery()` lease release race (§22) The release PATCH (`lease_duration_seconds=0`) could lose its CAS race against the in-flight lease-renewal loop and was being silently swallowed as a WARNING, leaving the lease live until natural expiry. Added bounded re-read + retry (5 attempts) so the release actually lands. Also fixed empty-string `lease_owner` / `lease_instance_id` (the validator requires all-or-nothing triplet; empty strings disabled lease handling). D-3 [MEDIUM] — `durable.__all__` exported non-public retry helpers `exponential_backoff` / `fixed_delay` / `linear_backoff` / `no_retry` were exported as top-level module functions; spec §32/§38 only documents them as `@classmethod` on `RetryPolicy`. Removed from `__all__` and from the top-level re-export. D-4 [LOW] — `_handle_suspend` missing `_retry_attempt: null` (§23.8 #3) Added the `_retry_attempt: None` clear to the suspend PATCH so the next turn always starts with a fresh retry budget, matching the multi-turn paths. Spec-side cleanup (impl is correct; SOT carried stale legacy text): - §53 suspend-write pseudocode: rewritten to omit output persistence (was still describing the pre-021 `_output` attachment write) - C-ATT-3: corrected to state outputs are not persisted at all - §B simpler-scenarios bullets: removed references to `payload.output` / `attachments._output` Tests: 725 passing (up from 620), 36 failing (down from 42). The 6 newly-passing tests are exactly the spec-required behavior the audit identified as drift (input promotion + multi-turn raise ordering + exit_for_recovery lease release + public surface). The remaining 36 failures all exercise removed-by-spec behaviors (legacy `@task(ephemeral=...)` kwarg, `MultiTurnTask._get/_list` private surface, `get_active_run(task_id)` 1-arg signature, etc.). Streaming: 99/99 passing (unchanged). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * agentserver: finalize feature branch — scrub internal-spec refs, version bump, stale-test cleanup, format Branch finalization sweep for the agentserver durable-task + streaming primitive work. All packages now build, lint, and test cleanly off the authoritative spec at `azure-ai-agentserver-core/docs/task-and-streaming-spec.md` — the only shipping reference for the new primitives. The internal numbered specs under `sdk/agentserver/specs/` (specs 001..022) are now gitignored local-only working documents and untracked. Scope: - **Stop tracking internal speckit specs** — six `sdk/agentserver/specs/` files are removed from the index per the existing `sdk/agentserver/.gitignore` rule; the SOT spec at `docs/task-and-streaming-spec.md` is now the canonical reference. - **Scrub internal-spec references** — every committed file under `sdk/agentserver/` no longer references internal spec ids (`Spec NNN`), functional-requirement ids (`FR-XXX`), user-story ids (`USn`), or internal gap-lists. Where the prose had a stable section pointer it was rewritten to reference the SOT by section number (e.g. `§11`); otherwise the reference was stripped and the substantive content preserved. Touches ~90 files (production code, tests, samples, developer guides, CHANGELOG). - **Version bumps**: - `azure-ai-agentserver-core` 2.0.0b6 → **2.0.0b7** (unreleased) - `azure-ai-agentserver-invocations` 1.0.0b5 → **1.0.0b6** (unreleased) + min-dep pin `azure-ai-agentserver-core>=2.0.0b7`. - **Rewrote the core 2.0.0b7 CHANGELOG entry** as a coherent developer-facing release note. Removed the internal cross-branch hand-off prose and the contradictory "added then removed" Task.get / TaskSnapshot bullets; the durable-task primitive ships as one coherent new feature with no migration story (nothing public was shipped previously). - **`@task` strictly rejects `ephemeral=` and `steerable=`** at decoration time (`TypeError`). One-shot is always ephemeral and never steerable; use `@multi_turn_task` for steerable chains. - **`RetryPolicy(retry_on=...)` validates non-tuple non-Exception arguments** (e.g. `retry_on=str`) with the canonical `"retry_on entries must be Exception subclasses"` message instead of leaking the underlying `TypeError: 'type' object is not iterable`. - **Stale tests removed or skip-marked** with explicit reason (file/method-level). All gone: - `test_get.py` — `Task.get()` / `TaskSnapshot` removed - `test_output_promotion.py` and `test_output_lifecycle.py` — output is no longer persisted (no `payload[output]`, no `_output` attachment) - 5 stale tests in `test_sample_e2e.py` (used removed `_list` / `_get` private surface or pre-redesign multi-turn completion semantics) - 3 stale tests in `test_retry.py` (used `@task(ephemeral=False)`) - `test_completed_with_ephemeral_false_retains_input` - `test_one_shot_input_cleared_at_terminal` - `test_steering_function_ignores_cancel_completes` - `test_queued_promotion_uses_cleared_input_slot` - One stale fixture in `test_decorator.py` updated. - `test_TaskExhaustedRetriesErrorDict_field_shape`: missing tuple-literal comma fixed. 4 cancellation-matrix tests are `@pytest.mark.skip(...)`-marked with a TODO pointing at the multi-turn steerable cancel / drain paths needing re-validation post-redesign (track as separate impl follow-up). - **Stale tests refreshed to current API**: - `test_durable_multiturn.py` (invocations e2e): raw output instead of `result.output`, `manager.provider.get(task_id)` instead of `_get(task_id)` - `test_lifecycle.py` orphan tests: `@task` instead of `@multi_turn_task` (one-shot `get_active_run` is 1-arg) - `test_cancellation_matrix.test_crash_recovery_re_invokes_with_persisted_input`: explicit `input_id="persisted"` so the new multi-turn 2-arg `get_active_run` matches - `test_etag_cas.test_terminal_412_lease_ours_retries`: asserts `suspended` (multi-turn return-X is implicit suspend), not `completed` - **Format pass** — `azpysdk black` across all four packages, including samples and docs. ~150 files reformatted to the repo-canonical `eng/black-pyproject.toml` profile. - **Net check-deltas vs origin/main baseline**: - tests: 762 passing in core, 213 in invocations (all PASS) - mypy: −3 errors (11 → 8 in core; rest pre-existing) - pylint: +2 issues (190 → 192 in core; rest pre-existing) - sphinx: no regression (same 2-warning baseline as main) - black: full pass (post-format) - **Merge from origin/main** (102 commits behind at start, including `azure-ai-agentserver-core 2.0.0b6` and `azure-ai-agentserver-invocations 1.0.0b5` releases). Conflicts in `CHANGELOG.md` x2 and `test_tracing.py` resolved.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * agentserver: spec 022 final — zero skips, zero legacy, all tests green Closes the spec-022 durable-task primitive redesign on this branch. No skipped tests, no stale tests, no legacy code paths remain. All 4 agentserver packages pass cleanly with zero failures. Impl gaps closed (was the 5 skipped tests blocking finalization): - Recovery-input precedence (SOT §16). On entry_mode == "recovered", the framework now ignores any new caller-provided input and replays the original turn from the persisted payload["input"]. The caller's input would be a semantic error on a recovered turn — we're picking up where the previous lifetime left off, not starting a new turn. - Multi-turn cancel transitions chain to "suspended" (SOT §11/§16). Previously the asyncio.CancelledError handler in _execute_task_loop only resolved the caller's future with TaskCancelled and left the record stuck in "in_progress" — the next .start / .run would (incorrectly) treat the chain as a dead-lease orphan and replay the cancelled input. Now _handle_multi_turn_failure is invoked on cancel; the chain transitions cleanly to "suspended" with input + _retry_attempt + _steering.active_input + any promoted _input attachment cleared atomically (§23.8 single-PATCH invariant). Queued steerers promote per FR-013 when steerable. - Per-turn watchdog rearm on steering drain (SOT §52). Added TaskManager._timeout_watchdogs registry + _spawn_watchdog_for_turn / _cancel_watchdog_for_turn helpers. Every drain re-entry point (4 sites in _execute_task_loop) cancels the prior turn's watchdog and spawns a fresh one bound to the new ctx.cancel, with a budget computed from the just-updated _turn_started_at. The queued turn now gets its full per-turn budget, not whatever was left over. - Queued-steerer cancel removes from queue. TaskRun.cancel() on a handle bound to a queued (not-yet-promoted) steering input now routes through a new TaskManager._cancel_queued_steering_input that atomically removes the queued slot from payload["_steering"]["pending_inputs"] (and deletes the associated _steering_input_<seq> attachment when present), then resolves the queued steerer's future with TaskCancelled. The active turn is unaffected. The handle is wired via a new queued_cancel_callback slot on TaskRun. - Delete-vs-promotion CAS race test setup stabilised: added an active_entered event so the test reliably observes the active turn entering before delete fires (the race itself was always handled correctly by the existing MultiTurnTask.delete / _resolve_queued_steerers_on_terminal machinery — the test was just under-synchronized). Legacy code removed: - _in_progress_was_abandoned_legacy helper + _LEGACY_INPROCESS_STALE_THRESHOLD_SECONDS constant in _decorator.py (replaced years ago by the lease-based reclaim path; only docstring references remained). - _legacy_task wrapper indirection in _decorator.py — validation overlay collapsed into the single canonical task definition. - TaskContext._suspend_internal scaffolding (never called from framework code post-redesign; bare return X is the only end-of-turn signal). - TaskManager._handle_suspend dead path (the Suspended-sentinel branch in _execute_task_loop was unreachable; multi-turn return-X / raise are the only end-of-turn paths and route through _handle_multi_turn_success / _handle_multi_turn_failure). - Suspended class in _run.py (and its import from _manager.py + comment in __init__.py). Stale tests removed (no longer track removed-by-spec behavior): - TestTaskOptionsMerge class (4 + 1 tests) in test_decorator.py - test_task_options_rejects_stale_timeout - test_underscore_namespace_not_enforced_by_primitive - test_default_namespace_has_no_framework_keys - test_task_get_list_renamed_to_private - test_task_cancelled (bare TaskCancelled exception shape) - test_steering_queue_9_cap / test_steering_queue_full_exception - test_resolve_raises_inputtoolarge_when_over_cap - test_input_too_large_remap_from_internal_input_key - test_task_run_delete_translates_hosted_conflict - test_platform_resume_entry_mode (handle_resume removed) - test_recovery_with_pending_inputs (legacy superseded-result) - test_steerable_via_options (Task.options removed) - test_multiturn_suspend_resume (ctx.stream removed) - test_langgraph_multiturn_interrupt_resume (handle_resume removed) - TestSSEStreamingE2E class (3 tests; migrated to streams registry) Test-suite scrubs of dead contract registry entries in test_contract_completeness.py for the deleted tests.

Mirrors the shape of azure-ai-agentserver-core/docs/task-and-streaming-spec.md (numbered sections, conformance items, worked examples) and is intended as the reference any language porting this contract works from. Covers: - §3 dispatch matrix (4 rows × Paths A/B/C × stream/no-stream) - §4 chain identity derivation + task_id partitioning - §5 _responses reserved namespace (response_id, background, disposition, last_sequence_number) - §6 perpetual conversation-scoped task model (Row 1 vs bookkeeping for Rows 2/3) - §7 recovery dispatch (re-invoke vs mark-failed; server_error payload shape) - §8 DurabilityContext + three-actor recovery contract + naive opt-out - §9 stream contract: persistence ordering, starting_after=, reset-on-in_progress, idempotent create/terminal, output_index slot semantics - §10 cancellation + cancellation x recovery composition - §11 steering: lock semantics, fork rejection (409 conversation_fork_not_supported), acceptance hook, queue delivery - §12 acceptance flow worked sequence - §13 recovery flow worked sequences (Row 1 stream, Row 2 non-stream, Row 4 no-op) - §14 conformance items (C-MATRIX, C-CHAIN, C-NS, C-PERPETUAL, C-DISPOSITION, C-SERVER-ERROR, C-DURABILITY-CTX, C-RECOVERY-MODEL, C-STREAM-ORDER, C-RECONNECT, C-RESET, C-IDEMPOTENT, C-INDEX-REUSE, C-CANCEL, C-CANCEL-RECOVERY, C-LOCK, C-FORK-REJECT, C-ACCEPT, C-STEER-DELIVERY, C-COMPOSE) - §15 worked storage timeline (2-turn chain + crash + recovery + fork race) - §16 storage layout (durable task / response / stream) - §17 composition constraints - §20 cross-references to durable-task-spec + dev guides No code or test changes. No drift: every claim derived from the current implementation on this branch (_durable_orchestrator.py, _orchestrator.py, _task_id.py, _acceptance.py, _durability_context.py, _response_context.py, store/_file.py, _endpoint_handler.py). No references to internal-only speckit specs. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * [agentserver] responses: tidy developer guides to be standalone + drift-free Audits and updates the two developer-facing guides so they: - Reflect the current state of the world accurately (durability focus). - Are framed as developer guides (why / how / when / what for) rather than retrospectives on internal work-in-progress. - Do not leak references to internal local-only specs or work phases. Changes: handler-implementation-guide.md - Replace the dead link to specs/durability-contract.md (does not exist) with a link to the in-package authoritative SOT spec responses-durability-spec.md. - Reframe the Durability intro to point at the SOT for the full matrix + termination paths + conformance items, while this guide remains the developer how-to. - Remove the 'Backward Compatibility' subsection that promoted is_shutdown_requested as a back-compat alias — nothing has shipped yet, so there is no predecessor to be compatible with. Developers use context.cancellation_reason; the redundant alternate is no longer documented. - Refresh the ResponseContext class stub to list the properties developers actually use (conversation_chain_id, cancellation_reason, durability) with pointers to the relevant sections. - Strip internal phase numbering from prose and code comments ('Phase 1 pre-entry cancel', 'Phase 3 cancellation', 'fresh entry's Phase 2') — replaced with plain behavioural prose. - Stop documenting that the library reconstructs internal types (record, parsed, runtime-state registration); reframe as 'rebuilds your ResponseContext transparently' and call out the same response_id / request / conversation_chain_id / cancellation signal guarantees in developer-visible terms. - Drop the 'conversation_chain_id follow-up in spec 013' reference — conversation_chain_id is shipped and documented; no follow-up framing. durable-responses-developer-guide.md - Replace both dead links to specs/durability-contract.md with the in-package SOT spec responses-durability-spec.md. - Fix the previously-wrong Path A/B/C definitions in the Configuration Matrix prose (it claimed A=client cancel, B=graceful shutdown, C=SIGKILL crash, contradicting the implementation). Updated to the termination-path semantics actually delivered by the framework: A=handler completes within grace, B=grace exhausted (in-process marker), C=crash or Path-B failure (next-lifetime recovery). - Remove '(added in this release)' framing around conversation_chain_id — it is just part of the API now, not a recent bump in an unreleased package. - Reword the local-dev provider section to describe the providers matter-of-factly rather than as 'added in this release' / 'already existed'. - Strip 'Phase 1 / Phase 2 / Phase 3 cancellation logic' from the Best Practices section, leaving the substantive guidance ('the same pre-entry / mid-stream / shutdown rules apply on recovered entries'). - Drop '(this work)' framing from the Layered Concerns section. No code changes. All cross-references between the two guides and to the SOT spec validated. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * [agentserver] responses: SOT spec — document the two valid handler execution models A reader asked why Rows 2/3 use a separate bookkeeping task instead of just running the handler inside the durable task body and using the existing 'disposition' metadata key to decide recovery action. Answer: both architectures satisfy the contract; the current Python implementation chose the bookkeeping pattern for historical layering reasons (the non-durable codepath predated the durability work, and bookkeeping was the lowest-friction way to add crash-recovery markers to Rows 2/3 without restructuring handler execution). Updates to docs/responses-durability-spec.md: - §6 intro: acknowledge that two architectures satisfy the perpetual- task contract for Rows 2/3 and point at §6.4 before reading §6.2. - §6.2: add an opening blockquote noting this section describes Model A from §6.4 (the bookkeeping pattern, as used by the Python implementation); ports using Model B (unified task) can skip it. Remove the duplicated completion-event pre-registration paragraph — that lives in the new §6.5 now. - §6.4 (new) — 'Implementation note: handler execution model': side-by-side comparison of Model A (bookkeeping pattern) and Model B (unified-task pattern). Documents the three differences (code shape, HTTP request coupling for Row 3, per-invocation overhead). States the Python implementation uses Model A for historical reasons; a port has free choice. Neutral framing — does not editorialise about which is better. - §6.5 (new) — 'Bookkeeping pattern — completion-event pre-registration': the pre-registration rule (previously in §6.2) re-homed here. Normative for Model A ports; ports choosing Model B can skip it. No code or behavioural change. The contract observable to handlers, clients, and operators is identical between the two models — only the internal handler-execution layering differs. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * [agentserver] responses: add RED conformance tests for spec 023 migration Phase 1 (RED-first, NON-NEGOTIABLE per Principles VII / X §4 / XII §3). 12 new tests added across two existing test files (per Principle XII §4 non-duplication — no new test files): tests/unit/test_durable_orchestrator.py - TestPrimitiveSelectionMatrix.test_pick_primitive_matrix (8 parametrized cases, one per row of the SOT §6.6 / spec-021 §7.3 matrix). Depth assertion per Principle XI: returned primitive must be the EXACT instance (`is` comparison) of one of the two registered task fns, not just 'a Task was returned'. - TestOrchestratorConstructionValidation.test_orchestrator_registers_both_primitives_on_construction. Construction-time validation per Constitution Principle V (fail-fast). - TestOrchestratorConstructionValidation.test_orchestrator_multi_turn_steerable_flag_propagated. tests/unit/test_conversation_lock.py - TestRow5SequentialTurnsExtendChain.test_conv_id_non_steerable_sequential_turns_extend_chain. Depth assertion per Principle XI: the orchestrator's `_pick_primitive` routes conv_id requests to the multi-turn primitive (NOT the one-shot), and turn 2 of the same chain succeeds (no TaskConflictError against a suspended chain). - TestRow5SequentialTurnsExtendChain.test_conv_id_non_steerable_concurrent_overlap_still_returns_409. Regression guard: TaskConflictError MUST still surface with current_status='in_progress' for the legitimate concurrent-overlap case.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * [agentserver] responses: per-request primitive dispatch (spec 023 Phase 2) Phase 2 implementation — turns the Phase 1 RED tests GREEN. Per the SOT §6.6 / spec-021 §7.3 matrix, now registers two underlying durable-task primitives per deployment and dispatches per request based on (conversation_id, previous_response_id, steerable_conversations): | store | conv_id | prev_id | steerable | Primitive | |-------|---------|---------|-----------|------------| | true | absent | absent | (any) | @task | | true | absent | present | False | @task | | true | absent | present | True | @multi_turn| | true | present | (any) | (any) | @multi_turn| CHANGES: _durable_orchestrator.py - _create_task_fn -> _create_task_fns; registers TWO primitives: _one_shot_task_fn (@task name='responses_durable_one_shot') and _multi_turn_task_fn (@multi_turn_task name='responses_durable_multi_turn', steerable=options.steerable_conversations). - task_fn property kept as a back-compat alias for _one_shot_task_fn so existing recovery-registration introspection still works (Principle XII §4 non-duplication / Principle XIII pre-existing test preservation). - Added _pick_primitive(ctx_params) implementing the matrix above. Return type explicit per Principle II: Task[dict[str,Any], None] | MultiTurnTask[dict[str,Any], None]. - start_durable now dispatches via _pick_primitive before calling .start(). One-shot path: task_id only (no input_id, no if_last_input_id — one-shot has no chain to extend). Multi-turn path: input_id=response_id + if_last_input_id=previous_response_id (chain extension). - TaskConflictError from the primitive ALWAYS propagates (was swallowed). Under the new model TCE always signals a real conflict; the steerable- input-queuing case does NOT raise TCE — it returns a TaskRun whose _queued_cancel_callback is set. Detected via that attribute to set freshly_started=False for the acceptance-hook path. - Three ctx.suspend(reason=...) call sites replaced with bare 'return None' (the framework's implicit-suspend signal for multi-turn bodies; for one-shot bodies it's just normal completion). - The shutdown-mid-handler 'leave in_progress for recovery' branch switched from 'raise CancelledError' to 'return await ctx.exit_for_recovery()'. CancelledError triggers the core manager's cancel-delete branch (one-shot ephemeral records are DELETED on cancel, breaking Row 1 Path B recovery). exit_for_recovery releases the lease without deleting, so the next-lifetime recovery scanner can re-fire the task. _orchestrator.py - _start_durable_background's TaskConflictError handler simplified: always propagates (was: only re-raised when steerable_conversations was True). Row 5 (conv_id + steerable=False concurrent overlap) now surfaces 409 correctly instead of silently falling back. The freshly_started=False -> input_queued=True branch is now keyed off start_durable's return value (no longer gated on steerable_conversations). _endpoint_handler.py - TaskConflictError handler updated: under the spec-022 narrow surface the exception carries only current_status (no task_id attribute). Error message + log message simplified accordingly. - LastInputIdPreconditionFailed handler updated: only actual_last_input_id is carried under the new narrow surface; expected_last_input_id was accepted-and-discarded. Logging line updated. azure-ai-agentserver-core/_metadata.py - Removed the underscore-prefix namespace check from TaskMetadata.__call__. The check contradicted the file's own header docstring (which says 'The CORE primitive does NOT enforce namespace-name conventions') AND it broke framework-layered code (the responses orchestrator's access to _responses). Wrapper-layer policy (DurabilityContext) still rejects underscore-prefixed names for handlers. - Updated TaskMetadata.__call__ docstring to reflect the corrected behaviour (wrapper-layer-enforced, not primitive-enforced). azure-ai-agentserver-core/tests/durable/test_metadata.py - ADDED the missing test_underscore_namespace_not_enforced_by_primitive test (referenced in test_metadata.py:245 as a pinned contract clause but never actually written — a pre-existing gap). azure-ai-agentserver-core/tests/durable/test_metadata_facade.py - PORTED (not deleted, per Principle XIII pre-existing test rule) the prior test_reserved_underscore_prefix_raises into test_reserved_underscore_prefix_accessible_at_primitive_level which asserts the correct behaviour (accessible, with cross-reference to the authoritative test in test_metadata.py). Tests updated (Phase 2 covers tightly-coupled test changes; Phase 3 will be lighter): tests/unit/test_durable_orchestrator.py - TestDurableOrchestratorTaskCreation rewritten to assert against both primitives (one-shot name 'responses_durable_one_shot' / multi-turn name 'responses_durable_multi_turn'); ephemeral assertion split (one-shot is True, multi-turn is False). - test_steerable_suspends_after_completion -> renamed test_steerable_returns_none_for_implicit_suspend; asserts the body returns None (no ctx.suspend(reason=...) call) under the new model. - test_non_steerable_does_not_suspend -> renamed test_non_steerable_returns_none_too; same shape. tests/unit/test_conversation_lock.py - TestConflictHandling.test_task_conflict_raises_on_start -> renamed test_task_conflict_propagates_from_start_durable; asserts TCE NOW propagates from start_durable (was: swallowed). - test_conflict_error_contains_task_id -> renamed test_conflict_error_contains_current_status; asserts the new narrow exception carries only current_status (not task_id). - test_orchestrator_run_background_conflict_returns_409_shape -> rewritten as test_one_shot_dispatch_propagates_conflict_too; asserts one-shot also propagates TCE (no silent fallback). - test_task_fn_registered_for_recovery updated to assert both registration names are present in the global descriptors registry. TEST SWEEPS (Phase 2 acceptance): responses unit + contract + e2e (no live): 1283 passed, 7 skipped core: 829 passed, 5 skipped exceeds planned baseline (1272 -> ~1280). R-2 review (Principle XIII): implementation turns all Phase 1 RED tests GREEN with no shape-only assertions; no phase-local hacks; no premature abstractions; existing tests ported (not deleted). Cross-phase coupling for Phase 3: orchestrator's public-surface (start_durable signature, task_fn alias) is stable; Phase 3 cleanups can rely on it. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * [agentserver] responses: tidy unit tests for spec 023 migration Phase 3 — removes residual 'ctx.suspend = AsyncMock()' patterns from test_conversation_lock.py and test_durable_orchestrator.py. These were the last vestiges of the pre-spec-023 unit-test convention where the task body's suspend-via-explicit-call was mocked + asserted; under the new model the body signals implicit-suspend via 'return None' and the mock is dead-but-harmless. Most Phase 3 work landed in Phase 2's commit 8d6512f8ee — the test renames + assertion updates were tightly coupled to the implementation rename + behavioural change (TaskConflictError propagation, name change, ephemeral-on-cancel branch), so splitting them would have made the diff harder to review (Constitution Principle XIII recurring failure mode 'pre-existing test deletion' is avoided by porting tests in the same commit that changes the surface they exercise). R-3 review (Principle XIII / XII §4): - Non-duplication rule honoured: zero new test files; all changes extend tests/unit/test_durable_orchestrator.py and tests/unit/test_conversation_lock.py in-place. - No pre-existing test deleted without justification: every removed test was renamed + repointed (test_steerable_suspends_after_completion -> test_steerable_returns_none_for_implicit_suspend; etc.). - Coverage preserved: the new tests cover at least the same behaviour the old tests covered, plus the new Spec 023 surface (_pick_primitive, _one_shot_task_fn / _multi_turn_task_fn, exit_for_recovery shutdown branch). Tests: 617 unit pass.

Per docs/responses-durability-spec.md §21 (discipline rule) and the spec 023 §4.1 doc-sync inventory, every implementation surface change from Phase 2 is mirrored in the relevant doc surface in this commit. docs/responses-durability-spec.md - §6 intro: new primitive-selection paragraph documenting the per-request dispatch (one-shot @task vs multi-turn @multi_turn_task) and cross-referencing §6.6. - §6.1: 'task body suspends via ctx.suspend(reason=...)' replaced with 'task body returns None (the framework's implicit-suspend signal for multi-turn primitives)'. - §6.6 (new): the full per-request primitive-selection matrix (5 rows × 3 inputs → primitive choice) with rationale per row. Documents that the choice is invisible to handlers and clients, that the task_id partition prefix (conv: / chain: / fork: / resp:) is independent of the primitive choice, and that the choice MUST be made at request-dispatch time (not deployment-config time). - §7.2: 'body suspends via ctx.suspend(reason='crash_failed'|'non_bg_crash_failed')' replaced with 'body returns None (implicit-suspend signal); the response store's failed terminal is the authoritative failure record'. - §11.1: extensive clarifier added. Distinguishes conv_id chains (sequential turns extend; only concurrent overlap returns 409) from fork-style requests (each gets its own task_id). Error body shape updated to reflect the spec-022 narrow exception surface (no task_id attribute on TaskConflictError). - §14 C-PERPETUAL: conformance item updated — 'MUST suspend (not return)' replaced with 'MUST signal implicit-suspend (in this implementation: return None from a @multi_turn_task-decorated body)'. docs/durable-responses-developer-guide.md - Configuration Matrix table notes: new conv_id chains clarifier added ('sequential turns extend the chain even when steerable_conversations=False; only overlapping (concurrent) turns return 409'). docs/handler-implementation-guide.md - No changes required. Verified (grep -n 'ctx.suspend\|@task(steerable\|ephemeral=False' returns zero hits) — the handler-facing prose was already framework-agnostic about which primitive backs the perpetual task. CHANGELOG.md - New 1.0.0b7 section populated per Principle III standard subsections (Breaking Changes / Bugs Fixed / Other Changes). Documents: (a) core dep bump to >=2.0.0b7; (b) the row-5 sequential-turn bug fix as a user-visible behaviour change; (c) the per-request primitive dispatch as an internal change; (d) the ephemeral=False storage overhead elimination as an internal optimisation; (e) the ctx.exit_for_recovery() shutdown-branch change as an internal consistency fix. SOT drift re-verification (step 25): $ grep 'ctx.suspend(' azure/.../hosting/_durable_orchestrator.py -> only a comment reference (no code) $ grep 'implicit-suspend\|@multi_turn_task' docs/responses-durability-spec.md -> 8 hits (correct shape) $ grep 'ctx.suspend(reason=' docs/responses-durability-spec.md -> none (correct) $ _pick_primitive impl reads side-by-side with SOT §6.6 -> rows match $ dev guides reference responses-durability-spec.md -> 3 hits (correct) R-4 review (Principle XIII): - Every §4.1 inventory item closed. - No sample silently ported (verified per §2.5: no sample uses the affected surfaces). - Doc cross-references resolve (relative links in docs/ tree). - CHANGELOG accurately reflects the change set; uses Principle III standard subsection ordering.

Black reformatted 71 files across azure/ + tests/ + docs/ — most are pre-existing format drift between the durable-tasks and responses branches (the merge brought files in mixed formatting states). All changes are pure-style; tests continue to pass (1283 + 7 skipped on the no-live sweep). Other Phase 5 gate results (recorded in spec 023 checkbox tracking): - pylint: 2 pre-existing import-errors flagged on store/_foundry_provider.py + _foundry_errors.py importing azure.ai.agentserver.core._platform_headers (a cross-package private import; pylint can't resolve it in isolated scan mode). Rating IMPROVED from 9.53 to 9.93. - mypy: 3 pre-existing type errors (Optional[ResponseContext] arg mismatches, _runtime_state Optional union-attr).

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * [agentserver] responses: add Row 5 e2e depth-coverage tests (audit gap fix) Audit follow-up to spec 023 Phase 1: the unit tests in tests/unit/test_conversation_lock.py::TestRow5SequentialTurnsExtendChain verify the orchestrator-dispatch contract (the correct primitive is selected, TaskConflictError propagates) but mock the framework boundary — they don't actually exercise two real POSTs through the chain to verify the e2e behavior the SOT §11.1 promises. Per spec 023 §4.1 Phase 1 step 4 depth assertion per Constitution Principle XI, the row-5 fix promised verification of: - chain's actual status between turns (suspended, not completed) - turn-2's persisted response.output matches the handler's emitted output - _responses framework metadata preserved across the turn boundary The audit surfaced that the unit tests don't cover (b)+(c). This commit adds the e2e coverage in tests/e2e/test_durable_multiturn_e2e.py::TestRow5ConversationIdNonSteerableE2E: 1. test_two_sequential_turns_extend_chain_and_complete — two POSTs on the same conversation, each reaching completed terminal. Asserts: - Both POSTs return 200 (NOT 409). - Distinct response_ids per turn. - Both turns share conversation_chain_id. - Handler observed turn_count=1 then turn_count=2 (proves _responses metadata persisted across the chain's suspend/resume boundary; would be 1+1 if chain reset). - Each turn's persisted response.output text contains that turn's input + count (proves the actual handler output landed, not a stale or generic value). 2. test_three_sequential_turns_extend_chain_correctly — same shape with 3 turns to verify the chain pattern scales monotonically. 3. test_concurrent_overlap_still_returns_409 — regression guard for the unchanged contract: concurrent overlap on the same conv_id returns 409 conversation_locked with the documented body shape. Uses an event-stream handler that emits response.created BEFORE sleeping so the first POST returns 200 immediately while the handler stays in_progress for the overlap window. Uses the existing tests/_helpers.hypercorn_server async-context-manager fixture so the AgentServerHost's lifespan triggers TaskManager initialization (TestClient skips lifespan for sync code paths and would silently fall back to the broad-exception bg fallback, defeating the test's purpose). Test sweep: 1286 passed (up from 1283; +3 new tests).

Adds 7 structural RED tests in tests/unit/test_bookkeeping_pattern_removed.py that assert the bookkeeping primitives (_BOOKKEEPING_EVENTS, _run_bookkeeping_body, ensure_bookkeeping_event, complete_bookkeeping_task, _complete_bookkeeping_task, _shielded_runner) are gone from the production code and that Row 3 dispatch uses await TaskRun.result(). All 7 RED today; will turn GREEN after Phase 2 implementation. Adds 2 race-guard tests in tests/e2e/test_no_fast_handler_race.py that fire FAN_OUT=30 fast Row 2/Row 3 handlers in parallel and assert all reach terminal. Pre-Phase-2 GREEN-by-mitigation; post-Phase-2 GREEN-by-construction. Step 6 (Row 3 HTTP semantics) is verified via existing tests at tests/contract/test_create_endpoint.py::test_sync_handler_exception_returns_500 and test_error_source_classification.py::test_sync_handler_exception_returns_upstream per Principle XII §4 non-duplication. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * [agentserver] responses: bookkeeping unification (spec 024 Phase 2) Unifies handler execution across Row 1/2/3 (store=true): the handler now runs inside the durable task body for ALL rows. The pre-Phase-2 "bookkeeping pattern" (separate durable task that just waits for the external handler to signal completion via _BOOKKEEPING_EVENTS) is deleted entirely. Deletions in azure/ai/agentserver/responses/hosting/_durable_orchestrator.py: - _BOOKKEEPING_EVENTS module-level registry - DurableResponseOrchestrator._run_bookkeeping_body method - DurableResponseOrchestrator.ensure_bookkeeping_event method - DurableResponseOrchestrator.complete_bookkeeping_task method - Fresh-entry mark-failed branch in _execute_in_task (handler now runs through the same path as re-invoke disposition; only the recovery branch differs) Deletions in _orchestrator.py: - ResponseOrchestrator._complete_bookkeeping_task method - _bookkeeping_noop_runner function - ensure_bookkeeping_event pre-registration call in _start_durable_background - _complete_bookkeeping_task call in _persist_and_resolve_terminal - The Row 2 (durable_bg=False+bg+store) double-path in run_background (asyncio.create_task(_shielded_runner) + separate bookkeeping task) Refactors in _orchestrator.py: - run_background: unified path for all store=true rows — calls _start_durable_background with disposition=re-invoke (Row 1) or mark-failed (Row 2). Row 4 (no store) keeps plain asyncio.create_task. - run_sync: handler runs inside durable task body; HTTP request awaits task_run.result() (or execution_task fallback). Preserves B8/§3.1 via record.response_failed_before_events + record.persistence_failed → _HandlerError → HTTP 500. Preserves B17 by distinguishing server shutdown (preserve for recovery) from client disconnect (evict + delete from store + raise CancelledError). Synthesises S-015 failed terminal when record.status stays in_progress after task completes. - _live_stream: fast path now covers only `not ctx.store` (Row 4 stream). ALL ctx.store stream paths use the durable + wire_stream pattern (was: only Row 1 stream). _unified_disposition selects re-invoke vs mark-failed per row. - _run_durable_stream_body: parameterised with background= kwarg (was hardcoded True). - _run_background_non_stream: skips transition_to when record.status is already terminal (avoids invalid failed→in_progress when shutdown marker beats handler). No-events fallback create_response now loads history_ids when previous_response_id is set. - _register_bg_execution: uses ctx.background instead of hardcoded True; condition broadened from (bg AND store) to (store AND (bg OR stream)) so Row 3 stream registers with background=False and events fan out to wire_stream. - _persist_and_resolve_terminal: emit-to-per-response-stream broadens from (bg AND store) to (store AND stream) so Row 3 stream terminal lands on wire_stream. Endpoint changes in _endpoint_handler.py: - handle_cancel: returns 404 (via fallback) for non-bg non-stream in-flight records (Rule B16). - handle_delete: same gating as handle_cancel. ResponseExecution.visible_via_get (models/runtime.py): adds B16 clause for non-bg non-stream — visible only after terminal status. Required because the unified path adds record to runtime_state at accept-time (vs. terminal-time pre-Phase-2). Tests: - tests/unit/test_bookkeeping_pattern_removed.py: 7 structural tests now GREEN (were RED at the Phase 1 commit). - tests/e2e/durability_contract/test_no_fast_handler_race.py: 2 race- guard tests added in Phase 1, now in durability_contract/ dir so they pick up the make_harness fixture. - tests/unit/test_response_execution.py + test_runtime_state.py: updated for the new visible_via_get B16 semantics. - tests/e2e/durability_contract/CONTRACT_COVERAGE.md: registers test_no_fast_handler_race.py.

Test-file rationale (Principle XII §4 non-duplication): no existing test file covers default-path-resolution for the durable task store or the responses-side stream/response store.

Proposal #9 (composition guard relaxation): - Deleted the steerable+!durable_bg ValueError guard in _options.py - The two options are independent — steering chains extend across turns regardless of the durability disposition (the lock/queue semantics are independent of crash recovery) Tests: - tests/unit/test_options_validation.py: updated test_durable_background_defaults_true → defaults_false; added test_steerable_with_durable_background_off_does_not_raise (inverted from old test_steerable_true_requires_durable_background_for_bg) - tests/unit/test_steering_integration.py::test_steerable_requires_durable → test_steerable_with_durable_background_off_does_not_raise (inverted) - tests/integration/test_steerable_with_durable_bg_off.py (NEW): Phase 4 step 24a RED-first e2e conformance for relaxed composition.

Closes Phase 5 of spec 024 (responses re-design). ## Approved proposals applied - #4 — `max_pending` option DELETED. - #5 — `context.is_shutdown_requested` property DELETED (subsumed by #11's new `context.shutdown: asyncio.Event`). - #6 + #10 — `context.durability.*` flattened onto `ResponseContext`: `is_recovery`, `is_steered_turn`, `pending_input_count`, `durable_metadata` (typed as the new public `DurableMetadataNamespace` Protocol). - #8 — `store_disabled` option DELETED; composition guard `steerable + store_disabled` deleted with the predicate. - #11 — cancellation surface alignment (composing causes): `context.cancel: asyncio.Event` + `context.shutdown: asyncio.Event` + `context.client_cancelled: bool` + `async exit_for_recovery() -> ExitForRecoverySignal`. The `CancellationReason` enum + `cancellation_reason` property are DELETED. Handler signature is hard-rejected at decoration time if it is not `async def` or does not take exactly 2 args. - #12 — `replay_event_ttl_seconds` option DELETED; replaced with hardcoded `_REPLAY_EVENT_TTL_SECONDS = 600.0` constant in `hosting/_routing.py` (B35 ≥ 10 min replay verified GREEN). - #13 — `DurabilityEntryMode` Literal alias + `entry_mode` field DELETED. Recovery detection is now `context.is_recovery`. The `_map_entry_mode` helper is replaced by `_is_recovered_entry`. ## Source changes - `azure/ai/agentserver/responses/_options.py`: deleted parameters and composition guard. - `azure/ai/agentserver/responses/_response_context.py`: flat field surface + composing cancellation events + `exit_for_recovery()` + `DurableMetadataNamespace` Protocol + `ExitForRecoverySignal` type alias. Class-level type annotations added so `get_type_hints()` and IDEs surface the precise types. - `azure/ai/agentserver/responses/_durability_context.py`: `DurabilityContext` class + `DurabilityEntryMode` alias DELETED. `_DeveloperMetadataFacade` retained as internal impl. - `azure/ai/agentserver/responses/__init__.py`: export `DurableMetadataNamespace`, `ExitForRecoverySignal`, `FileResponseStore`; drop `CancellationReason`. - `azure/ai/agentserver/responses/models/runtime.py`: `CancellationReason` enum DELETED. - `azure/ai/agentserver/responses/hosting/_routing.py`: `_validate_handler_signature()` hard-rejects sync + 3-arg handlers at decoration time. `_dispatch_create` invokes with 2 args. `_configure_streams_registry` uses the hardcoded TTL constant. Decorator + dispatch surface aligned with the new contract. - `azure/ai/agentserver/responses/hosting/_endpoint_handler.py`: cancel-bridge sets `context.client_cancelled` / `context.shutdown` instead of stamping `cancellation_reason`. Disconnect monitor + cancel endpoint + shutdown handler all switched to the new composing surface. `_create_response_context` aliases `context.cancel` with the execution-context cancellation signal. - `azure/ai/agentserver/responses/hosting/_durable_orchestrator.py`: stops constructing `DurabilityContext`; assigns flat fields directly on `ResponseContext`; cancel-bridge maps `ctx.shutdown` → `context.shutdown.set() + cancel.set()` and `ctx.cancel` (steering pressure) → `cancel.set()` ONLY (no cause flag). `_map_entry_mode` replaced by `_is_recovered_entry` boolean helper. - `azure/ai/agentserver/responses/hosting/_orchestrator.py`: terminal routing reads `context.shutdown.is_set()` / `context.client_cancelled` instead of the deleted enum. All 3 `self._create_fn(...)` invocations updated to 2-arg. ## Sample updates (Principle IX) - Samples 17, 18, 19, 20, 21, 22 (durable) all updated: 2-arg handler signature, `context.cancel.is_set()` cancellation observation, flat `context.is_recovery` / `context.durable_metadata` access, new shutdown-event surface via `_simulate_shutdown`. - Samples 18 + 19 helpers (`_open_session`, `_completed_phase_index`, `_build_resumption_response`) take `context` instead of `durability`. - All 17 samples import cleanly. ## Test updates - 25-test RED suite `tests/unit/test_phase5_api_simplification.py` — ALL GREEN. - Obsolete `tests/unit/test_cancellation_reason.py` + `tests/unit/test_durability_context.py` DELETED. - `tests/unit/test_durable_orchestrator.py` rewritten for `_is_recovered_entry` + flat-context model. - Bulk-conversion script applied across `tests/contract/`, `tests/integration/`, `tests/e2e/`: 3-arg → 2-arg handler signatures, `cancellation_signal.X` → `context.cancel.X`, `context.cancellation_reason == X` → cause-boolean checks, `context.durability.X` → flat field equivalents. - Durability-contract harness (`tests/e2e/durability_contract/`) updated to drop `store_disabled` env knob and pass flat-context semantics through. ## Final test results - Unit: 617/617 GREEN. - Contract: 372/377 GREEN (5 pre-existing baseline failures: streaming-persistence-failure + stream-disconnect — unchanged from Phase 4 baseline; addressed by Phase 7 conformance gap closure). - Integration: 39/39 GREEN. - Interop: 62/62 GREEN. - E2e (excluding hosted-only): 188/189 GREEN (1 skip). - Durability-contract suite: 37/37 GREEN. - Total: 1315/1320 GREEN (5 pre-existing baseline). Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * [agentserver] responses: SOT spec architectural rewrite post-unification (spec 024 Phase 6) Re-architect docs/responses-durability-spec.md for the post-spec-024 reality (bookkeeping unified into the task body in Phase 2; flat recovery + steering surface + composing cancellation surface in Phase 5). The spec is now standalone, language-agnostic, and replicable by a non-Python port. ## Sections rewritten ### §6 — Perpetual conversation-scoped task - §6 intro: dropped "two equivalent architectures" framing; one unified architecture described once. - §6.1 (Row 1): clarified disposition is `re-invoke` for crash recovery. - §6.2 (Rows 2/3): rewritten as "handler runs inside the task body with disposition=mark-failed" — same shape as §6.1. - §6.4 (Implementation note: handler execution model): DELETED. - §6.5 (Bookkeeping completion-event pre-registration): DELETED. - §6.6 (Primitive selection matrix): renumbered to §6.4. ### §7 — Recovery dispatch - §7.1 (re-invoke): rewritten for flat `context.is_recovery` / `context.durable_metadata` surface; dropped `entry_mode`, `retry_attempt`, `DurabilityContext.metadata` references. - §7.2 (mark-failed): rewritten as "task body persists failed and returns"; "completion event signal" references deleted. ### §8 — Handler-side recovery contract - §8 surface table rewritten for the flat fields: `is_recovery`, `is_steered_turn`, `pending_input_count`, `durable_metadata`. Old fields (`entry_mode`, `retry_attempt`, `was_steered`, `pending_inputs`, `metadata`) deleted. - §8.1 metadata semantics: documents the namespace-callable shape on `durable_metadata` and `flush()` durability fence; reserved `_`-prefix rule retained. ### §10 — Cancellation - Rewritten end-to-end for the composing-cause surface (`context.cancel: Event`, `context.shutdown: Event`, `context.client_cancelled: Bool`, `exit_for_recovery()` method). - Cause matrix added (5 trigger rows × 3 surface columns). - Steering pressure documented as "no cause flag" (matches task primitive contract). - `context.exit_for_recovery()` recovery-exit primitive documented: handlers MUST propagate via `return`, sentinel return value is framework-recognised. - §10.1 (Cancellation × recovery composition) updated for new surface; `STEERED` / `CLIENT_CANCELLED` / `SHUTTING_DOWN` enum rows replaced with cause-boolean equivalents. ### §3 — Dispatch matrix - Row 2/3 descriptions: "Bookkeeping-only durability" → "Crash-failed durability" (no more bookkeeping concept). - Termination paths table: "bookkeeping no-op / signal complete" → "task body returns"; "Bookkeeping body proactively persists" → "Task body persists"; Path C row updated. ### §13 — Worked sequences - Row 2 sequence: "ALSO start bookkeeping task with disposition= mark-failed (pre-register completion event)" + "asyncio.create_task (_shielded_runner)" → "start durable task with disposition=mark- failed" + "task body invokes handler (handler runs INSIDE the body)". - Recovery branch: "re-fire bookkeeping task body" → "re-fire task body" with `context.is_recovery=True`. ### §11 — Steering - `was_steered=True/False` → `is_steered_turn=True/False`. - Steering-pressure cancel signal described as "context.cancel Event set, no cause flag" (matches §10 surface). ### §14 — Conformance items - C-PERPETUAL: dropped "bookkeeping body MUST race three signals" language; describes shutdown-without-explicit-exit_for_recovery path. - C-DURABILITY-CTX: renamed and rewritten for the flat surface; type-annotated as `DurableMetadataNamespace` Protocol. ### §17 — Composition constraints - §17.3 (`steerable_conversations=true × durable_background=false`): rewritten to describe the relaxed composition (Phase 4) — handler runs inside the task body just like Row 1, only the disposition differs. - §17.4 (`background=false + steerable`): described as handler-in-task-body with HTTP request awaiting via `TaskRun.result()`. ### Other surface cleanups - `cancellation_signal` (handler arg) → `context.cancel event` throughout normative clauses. - `DurabilityContext` references → "recovery + steering context (flat fields on the response context)" with the type list inlined. - `replay_event_ttl_seconds` reference reframed as framework-internal with the "≥ 10 min" rule pinned to behaviour-contract Rule B35. - `entry_mode="recovered"` → `context.is_recovery=True`. ## Audit pass The §6 description of bookkeeping no longer exists. The §8 surface matches the implementation. The §10 cancellation contract matches the composing-event shape exposed by `ResponseContext`. Every mention of deleted symbols (`CancellationReason`, `DurabilityContext`, `store_disabled`, `max_pending`, `replay_event_ttl_seconds`, `entry_mode`, `retry_attempt`, `was_steered`, `pending_inputs`, `cancellation_signal`) has been rewritten or deleted.
