-:END:
-Build process-isolated chart journeys that distinguish surviving shared
-services and consumers from clean chart exit. Preserve original errors
-and deterministic phase evidence; do not declare a journey green merely
-because another chart remains usable.
-
-Next action: reconcile the current testing and evaluation branches and
-their actual Piker/Tractor imports, then implement a suite-owned pikerd
-with independent chart processes. No implementation has started for this
-handoff as of this entry; source/state inspection is recorded below.
-
-Context:
-Human-directed assignment to e2e_qa_mngr from proj_super. The source
-handoff describes proposed tests, not existing runnable nodes:
-[[file:/home/goodboy/repos/piker/wkts/ib_downstream_pin_eval/ai/plans/20261019-chart-disconnect-e2e-handoff.md][Chart disconnect and reattach specification and manual evidence]]
-
-Existing foundations, inspected 2026-10-20:
-- wkt/live_chart_qtractor at 4ab49082: structured lifecycle 1a2d4893,
-  prerequisite fixes 5c17419c, opt-in Kraken reproducer 4ab49082.
-  Application/test work is committed; only local workflow configuration
-  remains dirty. Use this as the initial working candidate, not proof
-  that the evaluation fixes are integrated.
-- wkt/human_iface_e2e at aadfd1cf is clean and supplies the headless
-  QApplication isolation foundation.
-- wkt/replay_provider_e2e at 06fee700 is clean. Its real feed/control
-  fixture has acknowledged sequence barriers. The observed disconnect
-  races justify narrow controlled input, not a replay-first rewrite.
-- wkt/ib_downstream_pin_eval remains at eed58566 with dirty dependency,
-  logger, daemon and EMS compatibility changes.
-- wkt/ib_disconnect_integration at c0dae89a contains committed IB
-  disconnect work; its provenance/tooling state remains dirty.
-- Tractor wkt/ctx_final_return_disconnect in address_logging_levels is
-  at 0553fcf8 with dirty final-Return guard and regression changes.
-  Read them as candidate evidence, not an already-landed fix.
-
-Reuse tests/ui/conftest.py, the Qtractor lifecycle regression,
-tests/conftest.py open_test_pikerd and owned config propagation, and
-the replay branch's acknowledged feed controls where applicable.

-[[file:/home/goodboy/repos/piker/wkts/replay_provider_e2e/plans/opencode/live-backend-chart-e2e-review.md][Live-provider-first roadmap]]
-
-The current sanitized live_chart_qtractor interpreter resolves Piker
-from that worktree but Tractor from its py313 site-packages; installed
-Trio is 0.32.0 and PyQt6 is 6.10.1. This is not the manual evaluation's
-Tractor checkout or PyQt6 6.11.0 environment. Resolve exact versions and
-module paths again before any comparison. Inspect the duplicate pytest
---ll registration blocker before selecting the evaluation environment.
-
-Concerns and authority:
-This assignment does not authorize commits, history changes, live IB
-connections, any orders, or attachment to the human's running daemon.
-Order journeys may be designed and implemented as gated tests; do not
-execute them without explicit authorization. Live-provider qualification
-requires explicit selection and applicable human permission.
-
-The existing Kraken run reached history and paper EMS but readiness
-preceded rt_linked.mode, Qt reported abstract paint calls, and teardown
-left a paperboi child. That exact orphan was subsequently stopped by
-human-authorized SIGINT. Guest completion did not prove descendant exit.
-
-Manual IB trials demonstrate daemon/survivor continuity, not clean exit.
-Cancellation-only groups, DebugRequestError, hard-reaping and SIGSEGV
-remain unresolved. Do not suppress any of these to make E2E green.
-
-Canonical native-crash investigation, separate from this test assignment:
-[[id:piker-qt6-chart-teardown-sigsegv][Diagnose Qt6 chart teardown SIGSEGV with native backtraces]]
-[[file:../ai/diagnostics/20261019-chart-253598/README.md][SIP wrapper access during PyQt atexit: diagnostics and limits]]
-The core locates the native fault; it does not establish the underlying
-ownership cause. This task records exit evidence without claiming repair.
-Coordinate order replay/cancellation assertions with
-[[id:piker-typed-clearing-migration][Strict typed clearing migration]];
-do not duplicate its protocol migration or infer it has landed.
-
-Execution:
-- [ ] Reconcile source revisions and dirty work before integrating; record
-  the selected branch, reused fixtures, and exact runtime imports.
-- [ ] Own registrar/pikerd A independently of chart processes B and C;
-  give each chart its own QApplication and Tractor root. Separate discovery
-  from listener addresses, use a test-unique registry and loopback port
-  zero, and assert actual chart listeners are nonzero and distinct.
-- [ ] Isolate config, storage, settings and account state before imports
-  in every child; never reuse human ports 6116/3333 or human accounts.
-- [ ] Provide an external observation/control channel and owned process
-  handles that outlive charts. Capture actor UUID/name/PID/listeners,
-  child relations and exact SHM ownership including unpublished child SHM.
-- [ ] Establish readiness after feed/history attachment, bound views,
-  FSP streams, search handlers and EMS entry. Race waits against original
-  process/session failure, not only timeouts.
-- [ ] Implement same-market alternating departures: ready B/C, close B,
-  prove the SAME C consumes a post-close quote/FSP update, reopen B,
-  close C, prove replacement B survives, then close/reopen the last chart.
-  Add the distinct-market variant to prove sibling-feed independence.
-- [ ] Implement last-consumer repeated reattachment to the SAME A and
-  service/client generations. Compare actual window close, structured
-  shutdown, root-only SIGINT and terminal-equivalent process-group SIGINT
-  as separate variants, with PID/PGID ownership recorded before signaling.
-- [ ] Drive actual search results with QtBot in the chart worker; compare
-  visible versus normally dismissed results before detach and reattach.
-- [ ] Gate startup cancellation with entered/release acknowledgements at
-  early acquisition, FSP child bootstrap before imports/registration,
-  history publication and FSP stream establishment. Hold only C's work,
-  retain B's progress, permit unwind, and prove a new C can start afterward.
-- [ ] Repeat gated startup aborts with no other consumer. Include debug
-  mode during FSP imports; retain the original interruption independently
-  from a secondary local-actor IPC stdio-lock DebugRequestError.
-- [ ] Implement separately selected order continuity journeys for Piker
-  paper EMS, IB paper-account broker-routed limits, and EMS-held dark
-  orders. Execution remains blocked pending explicit order authorization.
-  Include multi-expiry market-specific dialogs and cancellation of both
-  order types after reattach.
-
-Verification:
-- [ ] Report service survival and chart exit as separate outcomes even
-  when either fails. Collect survivor evidence after departure errors,
-  then aggregate originals rather than hiding them behind cleanup.
-- [ ] Prove fresh service RPCs and post-action provider data in the same
-  survivor, including FSP consumption. Deterministic inputs need a matched
-  sequence; live quotes need not change price. Sampler ticks alone fail.
-- [ ] Assert stable service/provider generations, owned child exit and
-  SHM lifetime according to its actual owner. Shared cached feed SHM may
-  remain with A; endpoint closure alone does not prove PID exit.
-- [ ] Fail clean-exit checks for SIGSEGV/abort, stuck children, hard reap,
-  unexpected debugger entry and cancellation-only application errors.
-  Do not blanket-suppress TransportClosed or mixed exception groups.
-- [ ] Preserve baseline/fixed results, stdout/stderr, return codes,
-  source versions, phase acknowledgements, actor/RPC/context identities,
-  cancellation provenance, and available fault-handler/core evidence.
-- [ ] For authorized order qualification, verify canonical OID/reqid
-  continuity, idempotent replay, market routing, working-order counts,
-  position continuity and terminal cancellation. Repeated status messages
-  alone do not prove duplicate orders. Cover reqid 5042-style error replies
-  with oid=None and the unsubmitted-order-None cancellation symptom.
-- [ ] Run each selected tier headlessly with bounded ownership-scoped
-  cleanup. Preserve fresh-process fixture isolation; no broad process
-  killing, SHM cleanup, or human-daemon access.
-
-Handback:
-Return results to source piker, task piker-chart-disconnect-reattach-e2e:
-- Selected implementation branch, exact source revisions and reused
-  fixtures, including any unintegrated prerequisites.
-- Exact implemented runnable test node IDs and synchronization gates;
-  distinguish proposed names from implemented nodes.
-- Baseline/fixed results with service survival and chart/process exit
-  reported independently, including unresolved failures.
-- Remaining coverage gaps, required public/live-IB qualification and
-  order authorization, linked to the separate native-crash concern.
-Use guarded store updates for evidence. Preserve all human-owned task
-and checkbox states; passing tests and commits are not acceptance.
