-# Piker Clearing Expert
-
-Use this mental model before touching order control or accounting:
-
-```text
-OrderClient / UI
-  -> emsd routes intent and owns order-dialog state
-  -> live brokerd OR paperboi executes and reports events
-  -> executing backend owns fill-to-accounting integration
-  -> emsd translates and broadcasts broker events
-  -> UI consumes order state and position summaries
-```
-
-The EMS is not the trade ledger. It correlates IDs, runs dark
-predicates, and relays lifecycle events. Paper and accounting-aware
-live backends may normalize fills into transactions, update local
-ledger/account state, and emit `BrokerdPosition` summaries. Inspect
-each live backend; this integration is not uniform.
-
-## Runtime ownership
-
-- `OrderClient` owns client intent and local sent-order tracking.
-- `emsd` owns `Router`, `DarkBook`, active `Status` dialogs,
-  subscribers, and `oid <-> reqid` correlation.
-- `brokerd.<broker>` owns credentialed live order control.
-- `paperboi.<broker>` owns simulated execution and paper accounting.
-- `TransactionLedger` owns trade-record persistence, not order state.
-- `Account` owns positions keyed by backend-system market identity.
-- UI `Position.update_from_msg()` is a summary reset, not durable
-  transaction accounting.
-
-For daemon placement, context streams, cancellation, and actor-local
-state, also load `piker-conc-expert`.
-
-## Event lifecycle
-
-1. A client sends `Order` or `Cancel` through `OrderClient`.
-2. `process_client_order_cmds()` creates or updates EMS `Status`.
-3. EMS routes a `BrokerdOrder` or stores a dark trigger predicate.
-4. The executing backend acknowledges with `BrokerdOrderAck`.
-5. EMS records the current `oid <-> reqid` relation.
-6. Accepted, ack-correlated status/fill events become client updates.
-7. The backend integrates fills into accounting when supported.
-8. A resulting `BrokerdPosition` is relayed through EMS to clients.
-
-Cancellation may arrive before acknowledgement. Preserve
-`Status.cancel_called`; once the ack supplies `reqid`, EMS can issue
-the deferred `BrokerdCancel`.
-
-## Identifier namespaces
-
-Never substitute one namespace merely because two values happen to
-match in a backend:
-
-| ID | Owner and invariant |
-|---|---|
-| `oid` | Stable client/EMS order-dialog ID across submit, modify, cancel |
-| `reqid` | Backend order-control ID established by an ack; it may change |
-| venue order ID | Native API identity; may differ from both IDs above |
-| `tid` | Stable clear ID used to deduplicate position events and TOML keys |
-| `fqme` | Piker-normalized market address and symcache lookup key |
-| `bs_fqme` | FQME without its final broker suffix |
-| `bs_mktid` | Backend-system market key and `Account.pps` key |
-
-Normalize every durably persisted `tid` to a stable string. Although
-`Transaction.tid` permits integers, TOML mapping keys do not.
-
-Paper transactions commonly set `Transaction.bs_mktid` to the full
-FQME. The embedded `Position.mkt.bs_mktid` can still retain the
-provider-native market ID. Check the concrete object and table owner
-before asserting key equality.
-
-## Accounting invariants
-
-- `Transaction.size` is signed; preserve side semantics during
-  broker normalization.
-- `Transaction` is the normalized in-memory interchange. Live ledger
-  records may remain backend-native and normalize through
-  `mod.norm_trade()` when read.
-- `Position._events` is keyed by `tid`; `add_clear()` is the
-  idempotence boundary.
-- `Position.ppu` and `Position.cumsize` are derived from transaction
-  events, not independent mutable truth.
-- Normalized accounting transactions need a stable, non-null
-  `bs_mktid`; `Account.pps` uses it as the position key.
-- `Account.update_from_ledger()` resolves market metadata from
-  `SymbologyCache.mktmaps` or its explicit fallback table.
-- UI position messages are projections. Do not feed their synthetic
-  reset event back into durable broker accounting.
-
-## Persistence contracts
-
-Trade ledgers live under the accounting ledger directory as
-`trades_<broker>_<account>.toml`. Top-level keys are transaction IDs;
-record schemas are backend-specific unless the paper engine wrote a
-normalized transaction dictionary.
-
-`open_trade_ledger()` writes on context exit when its data comparison
-detects a change or `rewrite=True`. Its snapshot is shallow, so nested
-in-place record mutation can evade dirty detection. Explicit writes can
-also fail inside fill handlers. Treat all persistence points as part of
-the live execution path.
-
-Accounts persist active positions. `dump_active()` separates open and
-net-zero positions. Do not assume `minimized_clears()` safely preserves
-size/PPU: current sign-transition and longer net-zero slicing lacks
-round-trip coverage and can retain the wrong event subset.
-
-## Market identity and symcache
-
-`SymbologyCache` has three distinct key-addressed mappings:
-
-- `assets`: provider asset ID to `Asset`;
-- `pairs`: native `bs_mktid` to backend pair `Struct`;
-- `mktmaps`: searchable FQME or explicit alias to normalized
-  `MktPair`.
-
-Search mapping keys, then resolve values. RapidFuzz treats mapping
-values as choices; passing `mktmaps` directly makes it operate on
-`MktPair` objects. Preserve in-memory aliases because IB can store both
-native IDs and FQMEs for one `MktPair`. Do not persist such aliases
-without fixing reload: `from_dict()` currently requires every key to
-equal `mkt.fqme`.
-
-## Change workflow
-
-Before editing:
-
-1. Identify the owning layer: client, EMS, executor, accounting, or UI.
-2. Write down every ID/key transition across that boundary.
-3. Trace both normal and cancel-before-ack event ordering.
-4. Determine whether records are native, normalized, or summaries.
-5. Check actor-local caches and context-exit writes.
-6. Add a deterministic regression at the narrowest broken contract.
-7. Run live/backend tests only when their credentials and side effects
-   are explicitly authorized.
-
-Do not fix an accounting defect by adding state to EMS, or fix an EMS
-correlation defect by rewriting durable transaction history.
-

-# Clearing And Accounting Architecture
-
-## Protocol direction
-
-Client-facing messages and broker-facing messages intentionally differ.
-
-```text
-client -> EMS
-  Order, Cancel
-
-EMS -> executor
-  BrokerdOrder, BrokerdCancel
-
-executor -> EMS
-  BrokerdOrderAck, BrokerdStatus, BrokerdFill,
-  BrokerdError, BrokerdPosition
-
-EMS -> subscribed clients
-  Status, BrokerdPosition
-```
-
-`Order` carries the client `oid`, account, market, price, size, action,
-and execution mode. `BrokerdOrderAck` establishes the executor's
-`reqid`; subsequent broker messages should carry that ID so EMS can
-resolve the client dialog.
-
-`Status` is mutable current dialog state, not a history envelope. Exact
-client states include `pending`, `open`, `dark_open`, `triggered`,
-`fill`, `closed`, `canceled`, and `error`. Audit existing translation
-before adding a state; backend `BrokerdStatus` vocabulary is narrower
-and current producers are not fully conformant.
-
-## EMS routing
-
-`_emsd_main()` serves each client/market context. The actor-local
-`Router` owns books, subscribers, order dialogs, and cached live trades
-relays. Paper mode opens per-symbol relay contexts under the same broker
-key, a current overwrite/pop hazard for concurrent paper symbols.
-
-`open_brokerd_dialog()` is the session live-versus-paper selection
-point:
-
-- live execution talks to `brokerd.<broker>`;
-- paper execution talks to `paperboi.<broker>`;
-- chart-only and paper sessions should not boot credentialed brokerd.
-
-Do not infer paper execution from each order's `exec_mode`. Session
-mode selects the executor; per-order mode primarily distinguishes dark
-from immediately routed orders, despite incomplete literal annotations.
-
-`process_client_order_cmds()` handles submit, modify, cancel, dark,
-and alert intent. It updates EMS dialog state before routing broker
-commands. `translate_and_relay_brokerd_events()` applies acks, statuses,
-fills, errors, and positions to dialogs and subscribers.
-
-The `DarkBook` stores local predicates and watches quote ticks. When a
-predicate triggers, `clear_dark_triggers()` emits the live broker order
-and updates the existing client dialog rather than inventing a second
-order identity.
-
-## Ack and cancel ordering
-
-Required actionable ordering is submit, ack, open, zero or more fills,
-then terminal status. EMS handles cancel-before-ack, but it does not
-buffer arbitrary status-before-ack events; those currently fall through
-as unhandled. Backends must ack before actionable statuses.
-
-The important race is:
-
-```text
-client Cancel(oid)
-  -> EMS has no reqid yet
-  -> mark Status.cancel_called
-BrokerdOrderAck(oid, reqid)
-  -> install mapping
-  -> send deferred BrokerdCancel(reqid)
-```
-
-Do not drop a pre-ack cancel and do not send a broker cancel with an
-`oid` unless the backend explicitly uses that value as its `reqid`.
-
-## Paper execution
-
-`PaperBoi` maintains simulated orders, opens the market feed, and fills
-orders when L1 ask/bid quotes cross their prices. `trade`/`last` ticks
-zip buy and sell iterators, so a lone resting side currently may not
-fill from those tick types. `fake_fill()` is the core fill-to-account
-path:
-
-1. emit `BrokerdFill`;
-2. emit terminal `BrokerdStatus` for the simulated order;
-3. construct a signed normalized `Transaction`;
-4. `TransactionLedger.update_from_t()`;
-5. `Account.update_from_ledger()`;
-6. persist the ledger and account;
-7. emit `BrokerdPosition` with current size and PPU.
-
-The protocol notifications and persistence occur in one task but are
-not a database transaction. If persistence fails after fill/status
-publication, restart/reconciliation behavior matters. Do not reorder
-the sequence casually.
-
-Partial fills currently reuse `oid` as `tid`. A later partial therefore
-overwrites the paper ledger record and is rejected by position-event
-dedupe. Fix unique fill IDs before relying on paper partial-fill math.
-
-`open_trade_dialog()` opens symcache, paper ledger, account, and feed
-resources under structured concurrency. An exception from any nested
-resource, including ledger context exit, cancels the dialog and its feed
-stream.
-
-## Live backend variation
-
-There is no universal live-broker accounting implementation:
-
-- IB normalizes execution/commission events, updates ledger/account
-  state, and emits position updates.
-- Kraken has backend trade normalization and position reconstruction,
-  but its live path writes account state without inserting every new
-  trade into `TransactionLedger`.
-- Binance currently relays venue order/position events and does not
-  share every local `TransactionLedger`/`Account` path.
-
-Inspect the backend's `broker.py`, `ledger.py`, and `norm_trade()` before
-moving generic logic. A paper behavior is not automatically a live
-backend contract.
-
-## Ledger normalization
-
-`TransactionLedger.data` is the durable record mapping. For paper it
-contains transaction-like dictionaries. For live brokers it can contain
-raw provider records.
-
-`iter_txns()` sorts records and chooses normalization:
-
-- paper uses `_paper_engine.norm_trade()`;
-- live accounts use `brokermod.norm_trade()`.
-
-Normalizer output should carry datetime, signed size, price, cost,
-FQME, backend market ID, and transaction ID. Some normalizers return
-`None` for unusable records; `iter_txns()` does not filter it, while
-`to_txns()` does. Audit direct iterator consumers.
-
-`write_config()` sorts records for stable persistence. Paper rewrite
-logic migrates old symbol fields and qualifies legacy FQMEs through the
-symcache. Search can return no matches; callers which select the first
-result need an explicit fallback or a descriptive failure policy.
-
-## Position event model
-
-`Position` holds a market and a transaction-event mapping. New clears
-are deduplicated by `tid`. Current size and PPU are recomputed from the
-event sequence.
-
-`Account.update_from_ledger()`:
-
-1. receives normalized transactions;
-2. resolves each market through `mktmaps` or a fallback table;
-3. looks up or creates the position by `Transaction.bs_mktid`;
-4. adds unseen clears;
-5. returns visited positions, including duplicates whose clear was
-   rejected by `add_clear()`.
-
-`minimized_clears()` intends to discard irrelevant history after
-net-zero or sign transitions, but current slicing is not proven safe
-and can reconstruct the wrong active size/PPU. Treat it as a known bug
-surface until sign-transition round trips are covered.
-
-`Position.update_from_msg()` serves UI summaries by replacing local
-event state with a synthetic clear representing reported size and PPU.
-That projection is intentionally lossy.
-
-## Symbology contracts
-
-`MktPair.fqme` is a normalized endpoint address assembled from pair,
-venue, expiry/contract information, and broker. `MktPair.bs_fqme`
-drops the broker suffix. `MktPair.bs_mktid` is the provider-native
-market identity.
-
-`SymbologyCache.load()` attempts to obtain provider assets and pair
-structs, calls `get_mkt_info()`, and populates conventional mappings.
-Assets are optional; missing/empty pair support returns early.
-
-```text
-assets[provider_asset_id] -> Asset
-pairs[pair.bs_mktid]      -> backend Pair Struct
-mktmaps[mkt.fqme]         -> MktPair
-```
-
-Some backends add aliases such as `mktmaps[bs_mktid]`. Search must
-return the matched mapping key rather than rebuilding a key from the
-value, otherwise aliases silently collapse. Current serialization then
-writes aliases which reload rejects because `from_dict()` asserts each
-key equals `mkt.fqme`.
-
-## Persistence boundaries
-
-`open_trade_ledger()` loads account TOML and compares a shallow snapshot
-in `finally`. Top-level additions/replacements trigger writes; nested
-in-place mutation may not. `open_account()` similarly mediates account
-state. These contexts run inside actor tasks, so serialization errors
-are runtime failures, not merely offline maintenance failures.
-
-When changing schemas:
-
-- preserve backend-native records unless migration is explicit;
-- keep old paper field migration deterministic;
-- avoid fuzzy qualification when an exact `bs_mktid`/FQME exists;
-- test context exit, not only in-memory updates;
-- inspect emitted positions after disk round trips.

-# Clearing And Ledger Gotchas
-
-## Trade dialog dies immediately after a fill
-
-Likely cause: an explicit ledger/account write in the fill handler, or
-a later context-exit write, raised after event publication.
-
-Inspect, in order:
-
-1. the first non-cancellation exception in the actor traceback;
-2. `PaperBoi.fake_fill()` or the live backend fill handler;
-3. explicit and context-exit `write_config()` calls;
-4. FQME/`bs_mktid` qualification and TOML-compatible values;
-5. the persisted ledger/account files for a partial update.
-
-Tractor cancellation logs are often the consequence. Root-cause the
-inner serialization, lookup, or normalization exception first.
-
-## `MktPair` has no `len()` in RapidFuzz
-
-Cause: a mapping of string keys to `MktPair` values was passed directly
-to `rapidfuzz.process.extract()`. Mapping values become fuzzy choices.
-
-Fix: search a list/view of string keys and resolve matched keys back
-through the original mapping. Do not add sequence methods to `MktPair`
-and do not use `processor=str` when aliases must be preserved.
-
-## Fuzzy qualification raises `IndexError`
-
-Cause: the caller selected the first match from an empty result after
-the score cutoff rejected every key.
-
-Decide explicitly whether to retain the input identity, reject the
-record with a descriptive exception, or obtain missing market metadata.
-Do not lower the cutoff blindly; the wrong market corrupts accounting.
-
-## Cancel is ignored or sent with the wrong ID
-
-Cause: confusion between client `oid` and backend `reqid`, commonly
-during cancel-before-ack ordering.
-
-Verify the ack installed both mapping directions and that
-`Status.cancel_called` survives until `reqid` exists. Log both IDs and
-the actor/backend account at every transition.
-
-## Fills appear but positions do not move
-
-Check these boundaries:
-
-- the backend emitted `BrokerdFill` but never normalized a transaction;
-- transaction size lost its buy/sell sign;
-- `tid` collided with an existing position event;
-- `Transaction.bs_mktid` selected a different `Account.pps` key;
-- `mktmaps` lacked the exact transaction identity;
-- position publication happened before accounting update;
-- the backend intentionally reports venue positions instead of local
-  ledger-derived positions.
-
-## Duplicate or inflated position size
-
-Do not deduplicate by price/time alone. Confirm stable transaction IDs,
-chronological sorting, and `Position.add_clear()` idempotence. Broker
-execution IDs and order IDs are not interchangeable.
-
-For partial fills, several `tid`s may correctly share one order
-`reqid`. Collapsing them loses clears; replaying one `tid` twice
-inflates nothing only if the dedupe boundary is preserved.
-
-Current paper fills use `tid=oid`, so later partials overwrite the
-ledger record and are deduplicated out of the position. Treat paper
-partial fills as broken until each clear receives a stable unique ID.
-
-## Paper and live state disagree
-
-Paper uses normalized local transactions and can use the full FQME as
-its account position key. A live backend may use native IDs, raw ledger
-records, or venue-reported positions.
-
-Compare normalized `Transaction`s and emitted `BrokerdPosition`s, not
-raw TOML dictionaries across backends.
-
-## Account appears under the wrong name
-
-Separate UI/EMS account aliases from backend account IDs and ledger file
-names. Backends may prefix account names for routing while persistence
-uses an unprefixed native account key.
-
-Trace account identity through `open_ems()`, broker dialog startup,
-ledger opening, and `BrokerdPosition.account` before changing naming.
-
-## A module-global cache is unexpectedly empty
-
-Symcache, clients, contracts, and order tables are actor-local. Data
-loaded in `datad` is not automatically available in `brokerd` or
-`paperboi`. Also, `_symcache._caches` is currently read but never
-populated, so do not assume repeated `open_symcache()` calls hit it.
-
-Load `piker-conc-expert` and audit actor-local globals, async caches,
-and dialog startup warming. Never rely on an import side effect from a
-sibling actor.
-
-## Teardown emits a cancellation storm
-
-Find the first application exception. Structured cancellation then
-closes feed streams, broker streams, and nested contexts. Avoid masking
-the originating exception with broad cancellation handling.
-
-For stream ownership and context cancellation semantics, use
-`piker-conc-expert`.
-
-## Broker status is logged as unhandled
-
-EMS currently accepts only ack-correlated `open`, `closed`, and
-`canceled` broker statuses. Declared `pending` and backend-produced
-`fill`/`filled` variants fall through, as do statuses arriving before
-ack. Verify producer vocabulary and ack ordering before adding another
-consumer branch.
-
-## Another client sees order or position events
-
-Current translation broadcasts order updates by FQME and positions to
-all attached clients; `Router.dialogs` is not used as an event privacy
-filter. Treat subscriber isolation as incomplete, not guaranteed.
-
-## Debug breadcrumb
-
-Capture one row per event with:
-
-```text
-actor, backend, account, fqme, bs_mktid,
-oid, reqid, venue_order_id, tid,
-message_type, status, action, signed_size, price, timestamp
-```
-
-Then compare:
-
-1. client command order;
-2. EMS status history;
-3. broker event order;
-4. normalized transactions;
-5. position event IDs and computed size/PPU;
-6. ledger/account disk state;
-7. emitted position summaries.
-
-This separates protocol loss, identity skew, accounting math, and
-persistence failure without guessing from UI state.

-# Clearing And Accounting Test Map
-
-## Deterministic first-pass tests
-
-Use the narrowest test that owns the broken contract:
-
-| Area | First target |
-|---|---|
-| Ledger/account persistence | targeted node in `tests/test_accounting.py` |
-| EMS bad-backend handling | `tests/test_ems.py::test_ems_err_on_bad_broker` |
-| IB request/response routing | `tests/test_ib_method_proxy.py` |
-| IB history normalization | `tests/test_ib_history.py` |
-| Service/actor startup | targeted node in `tests/test_services.py` |
-
-Known missing high-value regressions include paper partial-fill IDs,
-status-before-ack handling, `minimized_clears()` sign-transition round
-trips, nested ledger dirty detection, and symcache alias reload.
-
-For `SymbologyCache.search()` and paper ledger qualification, cover:
-
-- real `Asset` and `MktPair` values;
-- a native-ID alias and canonical FQME key;
-- the actual `TransactionLedger.write_config()` path;
-- persisted TOML fields after the round trip;
-- no use of live APIs or user configuration.
-
-## Side-effectful tests
-
-Do not run these without explicit authorization and the repository test
-harness guidance:
-
-- paper EMS tests which open live market/symbology feeds;
-- live Binance/Kraken feed suites;
-- IB account tests using configured accounts;
-- tests which write tracked ledger/account fixtures;
-- broker dialogs requiring credentials or venue connectivity.
-
-After any accounting test using `tests/_inputs`, inspect its diff. Some
-context managers can rewrite fixture ledgers on exit.
-
-## Regression design
-
-Prefer a direct contract regression over a full actor test when the
-failure is synchronous and deterministic. Use an actor-level test when
-the bug depends on:
-
-- ack/cancel or fill/status interleaving;
-- context cancellation or stream ownership;
-- actor-local state/cache separation;
-- daemon selection or startup;
-- publication ordering across EMS and broker streams.
-
-Every regression should document the original failure, triggering
-state, violated invariant, arrangement, and proof of the fix.
-
-## Verification layers
-
-1. `git diff --cached --check` for the exact staged boundary.
-2. Ruff with the repository's intended rule profile.
-3. A deterministic unit/filesystem regression.
-4. Adjacent accounting or EMS tests which do not require live state.
-5. Explicitly authorized backend/actor integration tests.
-
-Do not interpret a passing ellipsis-body or hard-skipped test as
-behavioral coverage. Read the selected node before using it as a gate.
-
-## Manual reconciliation check
-
-For production-only failures, compare one fill end to end:
-
-```text
-BrokerdFill
-  -> normalized Transaction
-  -> ledger record
-  -> Position._events[tid]
-  -> Position.cumsize / ppu
-  -> account TOML
-  -> BrokerdPosition
-  -> UI summary
-```
-
-All identities, sign, price, and account values should remain explainable
-at each arrow. A mismatch identifies the owning boundary for the next
-focused test.

-# Piker Concurrency & Runtime Expertise
-
-The distilled mental model for piker's distributed
-runtime: a `trio`-structured actor tree supervised by
-`tractor` (pinned to git main) where every long-lived
-subsystem is a named daemon-actor talking over
-ctx/stream IPC.
-
-## Actor tree & daemon taxonomy
-
-```
-pikerd                  root supervisor + registry
-├── datad.<broker>      feed bus, shm writers, tsp
-│                       history, symbol search
-├── brokerd.<broker>    live order-ctl ONLY; lazily
-│                       spawned by emsd, credentialed
-├── emsd                dark-clearing + order routing
-│   └── paperboi.<broker>  sim-clearing (paper mode)
-└── samplerd            singleton OHLC clock/increment
-```
-
-Key invariants:
-- `datad` hosts all `piker.data.validate._eps['datad']`
-  eps; `brokerd` only the `['brokerd']` (order-ctl)
-  ones. The `_eps` table in `piker/data/validate.py`
-  is the authoritative contract; `get_eps(mod, kind)`
-  introspects a backend's support.
-- `brokerd.<broker>` is booted in EXACTLY one place:
-  `open_brokerd_dialog()` in `piker/clearing/_ems.py`
-  (with a `portal:` override for the `piker ledger`
-  ad-hoc actor). Chart-only + paper sessions run with
-  ZERO brokerd procs. Never add a data-path spawn!
-- backends declare per-daemon-kind submods via
-  `_datad_mods`/`_brokerd_mods` in their
-  `__init__.py` (fallback: `__enable_modules__`).
-
-## Daemon lifecycle conventions
-
-Every daemon-kind follows the same trio of fns (see
-`piker/brokers/_daemon.py` + `piker/data/_daemon.py`
-as the canonical pair):
-
-- `_setup_persistent_<kind>()`: a `@tractor.context`
-  "lifetime fixture" run via
-  `Services.start_service_task()`; does console-log
-  setup ONCE for the actor, allocs any actor-global
-  state (eg. datad's `_FeedsBus`), then
-  `await ctx.started()` + `trio.sleep_forever()`.
-- `<kind>_init()`: builds `enable_modules` + actor
-  name `f'<kind>.{brokername}'` and copies backend
-  `_spawn_kwargs` (CRITICAL: `ib` needs
-  `infect_asyncio=True` in EVERY daemon-kind).
-- `spawn_<kind>()` + `maybe_spawn_<kind>()`: thin
-  wrappers over `Services.actor_n.start_actor()` and
-  `piker.service.maybe_spawn_daemon()` (registry
-  find-or-spawn w/ per-service-name locking).
-
-Caps-sec model: `enable_modules` gates RPC entry ONLY
-— python imports are unrestricted in-proc. Keep each
-daemon's enable set minimal; the (credentialed)
-`brokerd` must never RPC-enable `piker.data.*` feed
-mods.
-
-## Actor-local state: the #1 split hazard
-
-Module-globals and instance caches are PER-ACTOR.
-Anything that "just worked" because two subsystems
-shared a process will break when they're split into
-sibling actors. Canonical example: `ib`'s
-`Client._contracts` was warmed by feed-side
-`get_mkt_info()` in-proc; post datad/brokerd-split
-the trading actor must warm it itself (eagerly at
-`open_trade_dialog()` startup for open pps/orders +
-lazily per order request via
-`symbols.cache_contract()`).
-
-When moving code across actor boundaries ALWAYS audit:
-- module-global registries (`feed._bus`,
-  `_accounts2clients`, `_client_cache`, ..)
-- `@async_lifo_cache`/`maybe_open_context` caches
-  (NOTE: `async_lifo_cache` keys on POSITIONAL args
-  only; a cache-hit SKIPS the fn body and thus any
-  side-effect writes!)
-- logging handler placement (see gotchas.md)
-
-## tractor primitives as used here
-
-- `@tractor.context` eps: `await ctx.started(val)`
-  unblocks the caller w/ `val`; long-lived eps then
-  `ctx.open_stream()` or `sleep_forever()`.
-- discovery: `tractor.find_actor()` via
-  `piker.service.find_service()`;
-  `wait_for_actor(name, registry_addr=...)`;
-  `query_actor(name, regaddr=...)` yields
-  `(sockaddr, portal)`. Addrs are wrapped
-  `tractor.discovery._addr.Address` types — use
-  `wrap_address()` to normalize raw tuples and
-  `.unwrap()` for comparisons.
-- runtime-vars: `_runtime_vars['piker_vars']` is
-  inherited down the spawn tree; used eg. for
-  `piker_test_dir` config isolation — read LAZILY at
-  use-time, never at import time (subactors only get
-  vars post runtime-boot).
-- cancellation semantics (modern tractor): a
-  `ContextCancelled` whose `.canceller` is your own
-  actor is ABSORBED (clean exit, nothing raised);
-  single-exc groups collapse (`collapse_eg`) so eg.
-  a KBI propagates bare. Exc attrs:
-  `RemoteActorError.boxed_type` (not `.type`).
-
-## `to_asyncio` (infect-asyncio) integration
-
-For `ib` (and `deribit`) the backend client runs on
-an embedded `asyncio` loop via
-`tractor.to_asyncio.open_channel_from()` +
-`LinkedTaskChannel`.
-
-Rules learned the hard way:
-- a shared req/resp channel MUST correlate responses
-  to requests (see `MethodProxy._run_method()`'s
-  `mid` protocol in `piker/brokers/ib/api.py`):
-  caller cancellation (eg. `move_on_after` timeouts)
-  otherwise orphans a response and silently skews
-  every later result off-by-one.
-- the aio-side relay must catch + ship back ALL
-  (non-cancel) exceptions as `{'exception': err}`
-  resps; an escaping error kills the relay task ->
-  channel -> proxy nursery -> the whole dialog,
-  bypassing every caller-side guard.
-- `TrioTaskExited` ("child asyncio task is still
-  running?") on teardown is a known wart family;
-  prefer upstream `tractor` fixes over piker-side
-  bandaids.

-# Debug recipes: actor-system forensics
-
-Field-tested techniques for diagnosing hangs, wedges
-and cross-actor state bugs WITHOUT a debugger attached
-(or when `py-spy` ain't installed).
-
-## Wedged actor triage (no REPL)
-
-1. find the tree:
-   `ps -eo pid,etime,args | grep -E 'pytest|tractor._child'`
-   — long-`etime` `tractor._child` procs w/ a stuck
-   parent = wedge.
-2. kernel state:
-   `cat /proc/<pid>/wchan` + `status | grep -E
-   'State|Threads'` — `do_epoll_wait` + sleeping =
-   idle event loop, NOT cpu-spin.
-3. **the money read** — socket queues:
-   `ss -tnp | grep <pid>`
-   - `Recv-Q > 0` on the parent-IPC conn = the actor
-     STOPPED CONSUMING its msg loop (runtime bug),
-     parent is waiting on it.
-   - zero external (api/ws) conns = wedged before/
-     without provider IO; don't blame the network.
-   - `CLOSE-WAIT` lingerers = unclean peer teardown.
-4. cleanup: `pkill -f tractor._child` (NB: in
-   compound shell cmds `pkill`'s exit code poisons
-   `&&` chains — run it standalone).
-
-## Hang-proof test gating
-
-- per-suite, never combined (cross-suite session
-  state interacts w/ the 2nd-boot wedge):
-  `timeout -k 5 300 python -m pytest tests/<one>.py -q`
-- rc 124/143 = hang-kill -> retry ONCE before
-  investigating.
-- isolate a flaky test w/ a 3x loop; ~50% hit-rate
-  signatures match the known 2nd-boot wedge (see
-  gotchas.md).
-
-## Regression vs pre-existing attribution
-
-When a failure appears mid-refactor:
-1. `git stash -u` (or checkout the file subset) and
-   re-run the EXACT failing case at baseline.
-2. if baseline can't even run, selectively revert
-   ONLY the suspect layer:
-   `git diff <files> > /tmp/x.patch;
-    git checkout <files>` -> test ->
-   `git apply /tmp/x.patch`.
-3. flake-rate compare (3x runs) beats single-shot
-   conclusions.
-
-## Off-by-one / stale IPC resp detection
-
-Mismatched query->result content in logs (resp
-payload obviously for a prior request) = shared
-req/resp channel w/o correlation + a cancelled
-caller. Grep the ep for `move_on_after`/`fail_after`
-around proxied calls. Fix = req-id (`mid`) tagging,
-never "just a lock" (cancellation still orphans).
-
-## Logging-chain audits
-
-When records double-print or go bare (see gotchas.md):
-
-```python
-import logging
-l = logging.getLogger('piker.brokers.ib.broker')
-while l:
-    print(l.name, l.level, l.handlers, l.propagate)
-    l = l.parent
-```
-
-Exactly ONE stderr handler should exist in the chain,
-attached by the actor's daemon fixture.
-
-## Live actor-tree smoke (headless)
-
-Boot against an ALT registry port so a user's running
-stack is untouched; script in a REAL file (tractor
-children re-exec `__main__` from path — stdin scripts
-crash w/ `FileNotFoundError: .../<stdin>`):
-
-```python
-async with maybe_open_pikerd(
-    registry_addrs=[('127.0.0.1', 6979)],
-):
-    async with open_feed(['xbtusdt.kraken']) as feed:
-        assert await check_for_service('datad.kraken')
-        assert not await check_for_service(
-            'brokerd.kraken'
-        )
-```
-
-## In-proc fail-fast unit checks
-
-Spawn-path guards that raise BEFORE touching the
-runtime can be tested w/ a bare `trio.run()` (eg
-`spawn_brokerd('kucoin')` raising the datad-only
-error) — no pikerd needed.

-# Known gotchas: symptom -> cause -> fix
-
-A registry of distributed-runtime failure modes hit
-(and diagnosed) in the field; check here FIRST when a
-log/traceback matches.
-
-## "Can not order ..., no qualified contract cached"
-
-- **Symptom**: `RuntimeError` from
-  `ib.api.Client.submit_limit()` w/ empty
-  `Client._contracts` in `brokerd.ib`.
-- **Cause**: per-actor cache never warmed; feed-side
-  qualification now lives in `datad.ib`.
-- **Fix(ed)**: eager warmup at `open_trade_dialog()`
-  start + lazy per-order `get_mkt_info()` +
-  `cache_contract()` (writes BOTH `mkt.bs_fqme` and
-  `mkt.fqme` keys; different consumers read each!).
-
-## Search returns results for the WRONG pattern
-
-- **Symptom**: fqme search for 'gld' returns nvda
-  results; next query returns the prior query's set.
-- **Cause**: `MethodProxy` channel off-by-one — a
-  caller cancelled (search `move_on_after` timeout)
-  after sending its request orphans the response;
-  every later caller consumes the previous resp.
-- **Fix(ed)**: `mid` req-id correlation in
-  `_run_method()` + relay; stale resps are dropped w/
-  a "Dropping stale method-resp" warning. If that
-  warning spams, some caller is being cancelled
-  mid-call habitually — find + fix its timeout.
-
-## One bad request crashes a whole dialog/actor
-
-- **Symptom**: `TrioTaskExited` storm + nursery
-  teardown after a single method error (eg ambiguous
-  contract `AttributeError`).
-- **Cause**: exception escaped the aio-side relay
-  loop (`open_aio_client_method_relay()`) killing
-  channel + proxy nursery; caller-side `try/except`
-  CANNOT catch it.
-- **Fix(ed)**: relay catches `Exception` -> ships
-  `{'exception': err, 'mid': ...}` resp; order
-  handler converts to EMS `BrokerdError` msgs.
-
-## Ambiguous ib contracts -> `NoneType` attr errors
-
-- **Symptom**: `'NoneType' object has no attribute
-  'primaryExchange'` in `find_contracts()`.
-- **Cause**: `qualifyContractsAsync()` returns `None`
-  entries for ambiguous (eg venue-less stonk fqme
-  matching multiple listings: 'gld' -> ARCA/USD +
-  VENTURE/CAD).
-- **Fix(ed)**: filter `None`s + raise descriptive
-  `ValueError` ("use 'gld.arca.ib'").
-
-## Double-printed log records (same task id, 2x)
-
-- **Symptom**: every record from some subsys printed
-  twice w/ identical task ids.
-- **Cause**: stderr handlers attached at TWO levels
-  of one logger-propagation chain (eg daemon fixture
-  on `piker.brokers.ib` + an ep calling
-  `get_console_log(name=__name__)` on the child).
-  tractor's handler-dedup only checks the SAME
-  logger, not ancestors.
-- **Rule**: console handlers are attached ONCE per
-  actor in the `_setup_persistent_*()` fixture; eps
-  needing a different level use `log.setLevel()`
-  ONLY, never `get_console_log()`.
-
-## Bare/non-colorized log lines
-
-- **Symptom**: records w/ no timestamp/actor prefix.
-- **Cause**: NO handler anywhere in the emitting
-  logger's chain -> stdlib `logging.lastResort`. Post
-  actor-splits, a daemon fixture may only cover its
-  own subsys subtree (eg datad's `piker.data.*` but
-  not the backend's `piker.brokers.<broker>.*`).
-- **Fix(ed)**: `_setup_persistent_datad()` enables
-  BOTH `piker.data.<broker>` and
-  `piker.brokers.<broker>` subtrees.
-
-## 2nd in-proc runtime boot wedges (~50%)
-
-- **Symptom**: test hangs when one test proc boots a
-  2nd `pikerd` (eg `test_multi_fill_positions`'s
-  persistence re-check); a zombie `*.{broker}` child
-  lingers w/ unread bytes in its parent-IPC Recv-Q.
-- **Cause**: pre-existing `tractor`-main runtime
-  teardown bug (confirmed independent of piker-layer
-  changes via revert-testing 2026-06).
-- **Mitigation**: run suites per-file wrapped in
-  `timeout -k 5 300 ...`; retry once on rc 124/143.
-  Do NOT chase as a regression of unrelated changes.
-
-## ib client-id collisions post-split
-
-- **Symptom**: 2nd ib daemon burns the full
-  conn-timeout retry cycle connecting to gw/tws.
-- **Cause**: `datad.ib` + `brokerd.ib` both default
-  `client_id=6116` w/ linear `+i` retries.
-- **Fix(ed)**: role-based offsets in
-  `load_aio_clients()`: datad +16, ad-hoc (test/cli)
-  actors +32.
-
-## `async_lifo_cache` skipped side-effects
-
-- **Symptom**: a fn's cache-write side effect
-  (eg `get_mkt_info()` -> `_contracts`) missing for
-  a 2nd client/proxy.
-- **Cause**: cache keys on POSITIONAL args only; a
-  hit skips the body entirely.
-- **Rule**: never rely on cached-fn side effects;
-  perform required writes explicitly at the call
-  site (eg `cache_contract()` after `get_mkt_info`).

-# piker project store
-
-`current.org` contains the intact piker scope moved from the
-LNS working corpus. Task/checkbox states, carry metadata and prose
-remain human-owned. `sources.toml` selects this branch's store.
-
-Read the local `taken` skill through `.agents/skills/taken/SKILL.md`.
-It requires a complete-file revision guard for each authorized save.
-Use an explicitly selected source; do not write a global LNS copy.
-This migration preserves a historical project scope, not a claim that
-its old task descriptions or branch paths reflect current reality.
-
-The global storespace is registered in the LNS migration worktree's
-`taken/sources.toml`. Modden, Tractor and Piker include snapshots of their pre-existing
-local stores. The LNS consolidation ledger pins those inputs. Before
-landing, reconcile any newer edits there and retarget active agents;
-do not overwrite another agent's source or infer acceptance.
-
-Before removing this migration worktree after landing, update the
-global registration and the cross-repository taken skill link to the
-landed locations. The skill link intentionally points to the Taken
-migration branch until that code and documentation land.

-Build process-isolated chart journeys that distinguish surviving shared

-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.

-# Split `brokerd.<broker>` into trading-only `brokerd` + new `datad.<broker>`
-
-## Context
-
-Today a single `brokerd.<broker>` actor hosts BOTH concerns:
-
-- **data feed service tasks**: the `_FeedsBus` + `open_feed_bus()` ep (`piker/data/feed.py:464`), per-symbol `allocate_persistent_feed()` tasks (shm writers via `sample_and_broadcast()`, history backfill via `piker.tsp`), plus backend eps `stream_quotes`, `open_history_client`, `open_symbol_search`, `get_mkt_info` from `piker/brokers/<backend>/feed.py`/`symbols.py`,
-- **live order-control tasks**: `open_trade_dialog()` from `piker/brokers/<backend>/broker.py`, driven by `emsd`.
-
-The codebase already anticipates this split: `piker/data/validate.py:70-91` groups backend eps into `'datad'` vs `'brokerd'` kinds, `piker/brokers/ib/__init__.py:62-70` already declares `_brokerd_mods`/`_datad_mods`, and `piker/brokers/_daemon.py:62` carries the literal TODO *"rename the daemon to datad prolly once we split up broker vs. data tasks into separate actors?"*. This work executes that split.
-
-**User-decided constraints:**
-
-- `datad.<broker>` is a **sibling** of `brokerd.<broker>` under `pikerd`, spawned via the existing `Services` + `maybe_spawn_daemon()` machinery (`piker/service/_daemon.py:46`).
-- **Hard cutover, staged by layer** — no dual-mode runtime flag; every stage lands fully working.
-- Post-split `brokerd` is **trading-only and lazily spawned solely by emsd's** `open_brokerd_dialog` path; UI/CLI/feed code never spawns it. Chart-only and paper sessions run with **zero** brokerd processes.
-
-## Target topology
-
-```
-pikerd
-├── datad.ib      feed bus, shm writers, tsp history, symbol search
-├── brokerd.ib    open_trade_dialog only (EMS-spawned, lazy)
-├── emsd
-│   └── paperboi.ib   (paper mode; opens its feed via datad)
-└── samplerd
-```
-
-## Key verified facts (load-bearing)
-
-- `feed.portals` has exactly ONE trading consumer: `piker/clearing/_ems.py:671` (`portal = feed.portals[brokermod]` → handed to `open_brokerd_dialog`). This is the single coupling forcing feed + trading into one actor.
-- `assert 'brokerd' in servicename` at `piker/data/feed.py:502` is the only actor-name assert in the tree.
-- `piker ledger` (`piker/accounting/cli.py:100-157`) is a hidden consumer: it calls `broker_init()` directly, spawns its own ad-hoc actor, enters `_setup_persistent_brokerd`, then calls `open_brokerd_dialog(brokermod, portal, ...)` **with an explicit portal** — the new signature must keep a `portal:` override param.
-- kraken's feed→broker coupling is mild: `kraken/broker.py:77-81` imports `NoBsWs`/`open_autorecon_ws` (really from `piker.data._web_bs`) and `stream_messages` (pure parser) from `feed.py`. In-process imports only — `enable_modules` gates RPC, not imports. No live shared state; each actor opens its own WS.
-- ib: default `client_id=6116` (`ib/api.py:1320`) with linear retry `clientId=client_id + i` (`:1403`). Two ib actors connecting concurrently will collide → needs a role-based id offset. Both daemons need `_spawn_kwargs={'infect_asyncio': True}` (copied by both init fns).
-- binance has no `symbols.py` (`get_mkt_info`/`open_symbol_search` live in `binance/feed.py`); kucoin/questrade/robinhood are flat single-file with NO `__enable_modules__`; deribit has no `broker.py`.
-- `tests/test_services.py:80,185` assert `brokerd` actor names incl. the paper-mode flow asserting `brokerd.kraken` spawns (`:229,:237`) — must invert post-split.
-- `_root_modules` (`piker/service/_actor_runtime.py:156`) must gain the new datad daemon mod so `pikerd_portal.run(spawn_datad, ...)` resolves.
-- `piker/brokers/core.py:175` `symbol_search` does `portal.run(search_w_brokerd)` where the target fn lives in `piker.brokers.core` → that mod must stay RPC-enabled in datad.
-
-## Module decision
-
-New file **`piker/data/_daemon.py`** hosts all datad machinery (`_setup_persistent_datad`, `datad_init`, `spawn_datad`, `maybe_spawn_datad`, `_datad_service_mods`). Mirrors the `piker.brokers._daemon` / `piker.data._sampling` (samplerd) per-subsystem convention and satisfies the existing TODO at `brokers/_daemon.py:49` ("move this def to the `.data` subpkg"). `piker.brokers._daemon` keeps brokerd-only code, slimmed. Do NOT over-DRY the two ~40-line init fns into a shared factory yet (samplerd precedent accepts the duplication).
-
----
-
-## Stage 0 — prep: backend module grouping + ep introspection (no topology change)
-
-1. `piker/data/validate.py`: add a `get_eps(mod, kind) -> dict[str, Callable]` helper returning the backend's defined eps for a daemon-kind from `_eps` (missing eps excluded). Used later by both init fns + fail-fast checks.
-2. Declare daemon-kind module groups in each split backend's `__init__.py`, keeping `__enable_modules__` as the (deduped) union so behavior is unchanged:
-   - `kraken`: `_brokerd_mods = ['api', 'broker']`, `_datad_mods = ['api', 'feed', 'symbols']`
-   - `binance`: `_brokerd_mods = ['api', 'broker']`, `_datad_mods = ['api', 'feed']`
-   - `deribit`: `_brokerd_mods = []`, `_datad_mods = ['api', 'feed']`
-   - `ib`: adjust existing groups so each includes `'api'`
-   - flat backends (kucoin etc.): no attrs — init fns fall back to enabling just `modpath` (existing behavior).
-3. Hygiene: `kraken/broker.py:77-81` imports `NoBsWs`/`open_autorecon_ws` from `piker.data._web_bs` directly (keep the `stream_messages` import from `.feed`).
-
-**Gate**: full pytest green, zero behavior change.
-
-## Stage 1 — introduce `datad` daemon machinery (additive)
-
-New `piker/data/_daemon.py`:
-
-- `_datad_service_mods: list[str]` — datad-always-enabled mods (successor to the data side of `_data_mods` from `brokers/_daemon.py:52`): `['piker.brokers.core', 'piker.brokers.data', 'piker.data', 'piker.data.feed', 'piker.data._sampling', 'piker.data._daemon']`.
-- `_setup_persistent_datad(ctx, brokername, loglevel)` — `@tractor.context` fixture; logging boilerplate (as `_setup_persistent_brokerd:81-88`), then allocates the actor-global feed bus exactly as the brokerd fixture does today (`brokers/_daemon.py:105-121`): `assert not feed._bus`, open service nursery, `feed.get_feed_bus(brokername, service_nursery)`, `ctx.started()`, `sleep_forever()`.
-- `datad_init(brokername, ...)` — mirrors `broker_init()` (`brokers/_daemon.py:132`): actor name `f'datad.{brokername}'`, copies backend `_spawn_kwargs` (**critical for ib infect_asyncio**), builds `enable_modules` from `getattr(brokermod, '_datad_mods', getattr(brokermod, '__enable_modules__', []))`.
-- `spawn_datad(brokername, ...)` — mirrors `spawn_brokerd()` (`brokers/_daemon.py:202`): `Services.actor_n.start_actor(dname, enable_modules=_datad_service_mods + backend_mods, ...)` + `Services.start_service_task(dname, portal, _setup_persistent_datad, ...)`.
-- `maybe_spawn_datad(brokername, ...)` — wraps `maybe_spawn_daemon(service_name=f'datad.{brokername}', service_task_target=spawn_datad, ...)` exactly like `maybe_spawn_brokerd` (`brokers/_daemon.py:256`).
-
-Supporting edits:
-
-- `piker/service/_actor_runtime.py:156`: add `'piker.data._daemon'` to `_root_modules` (keep `'piker.brokers._daemon'`).
-- `piker/service/__init__.py`: re-export `spawn_datad`/`maybe_spawn_datad` next to the brokerd ones (`:56-57`).
-- `tests/test_services.py`: new `test_datad_spawn` — `open_test_pikerd` + `maybe_spawn_datad('kraken')` + `ensure_service('datad.kraken')`. (Do NOT route a feed through it yet — `open_feed_bus`'s assert still says brokerd.)
-
-**Gate**: suite green + new spawn test; nothing routes through datad yet.
-
-## Stage 2 — clearing layer: emsd self-spawns brokerd (decouple from `feed.portals`)
-
-Sequenced BEFORE the feed cutover so live trading works at every boundary (otherwise `feed.portals` would hand emsd a datad portal).
-
-`piker/clearing/_ems.py`:
-
-1. `open_brokerd_dialog()` (`:336`) new signature: `(brokermod, exec_mode, fqme=None, portal: tractor.Portal|None = None, loglevel=None)`. Internals: keep trades-ep detection (`:400-417`); acquire the brokerd actor ONLY when a live ep will actually open, via a small inner `@acm _acquire_live_portal()` that yields the passed `portal` if given (the `piker ledger` path) else `async with maybe_spawn_brokerd(brokermod.name, loglevel=loglevel)` — **the single place brokerd boots post-split**. Move the eager `portal.open_context(trades_endpoint, ...)` construction (`:425`) inside that block; the paper short-circuit (`:432`) never touches it.
-2. `Router.maybe_open_brokerd_dialog()` (`:581`) — drop the `portal` param; `Router.open_trade_relays()` (`:640`) — delete `portal = feed.portals[brokermod]` (`:671`) and the pass-through (`:685`).
-3. `piker/accounting/cli.py:144`: switch to keyword form `open_brokerd_dialog(brokermod, exec_mode=..., portal=portal, loglevel=...)`.
-
-Pre-cutover this is a pure refactor: emsd's `maybe_spawn_brokerd` just *finds* the already-running brokerd via the registry.
-
-**Gate**: `tests/test_ems.py` + services suite green; manual paper order on kraken; `piker ledger` smoke.
-
-## Stage 3 — feed layer hard cutover to datad
-
-1. `piker/data/feed.py`: import `maybe_spawn_datad` (replacing `maybe_spawn_brokerd`, `:56-58`); `open_feed()` `:895` → `maybe_spawn_datad(...)` (rename `brokerd_ctxs` → `datad_ctxs`); `open_feed_bus()` `:502` → `assert 'datad' in servicename`; comment sweep.
-2. `piker/brokers/_daemon.py` `_setup_persistent_brokerd()`: slim to trading-only fixture — logging setup, `ctx.started()`, `sleep_forever()`. Drop the bus alloc, `assert not feed._bus`, the service nursery (backend `open_trade_dialog` ctxs own their task trees), the `eg.ExceptionGroup` handler, and the stale `_FeedsBus` TYPE_CHECKING import. (`piker ledger`'s ad-hoc actor enters this same slimmed fixture — exactly what it needs.)
-3. Repoint remaining data-flavored spawn sites `maybe_spawn_brokerd` → `maybe_spawn_datad`:
-   - `piker/ui/_app.py:40,57` (symbol search; optionally rename `install_brokerd_search` → `install_datad_search`, def at `piker/data/feed.py:766`)
-   - `piker/brokers/core.py:33,175` (`symbol_search`)
-   - `piker/brokers/cli.py:38,190,320` (`brokercheck`, `record`)
-   - `piker/ui/cli.py:30,72,121` (legacy kivy monitor/optschain) + best-effort `piker/ui/kivy/option_chain.py:498` `wait_for_actor('brokerd')` → `'datad'`
-4. `tests/test_services.py`: `:80,:185` `actor_name = 'datad'`; paper-mode test asserts `datad.kraken` + `paperboi.kraken` + `emsd` AND adds the headline negative check: `assert 'brokerd.kraken' not in services.service_tasks`.
-
-**Gate**: full suite with inverted assertions; manual: chart on binance/kraken shows `datad.<broker>` in `piker services` and NO brokerd; paper order fills; symbol search works; history backfill sane.
-
-## Stage 4 — caps-sec slimming, validation, ib client-id
-
-1. `piker/brokers/_daemon.py`: delete `_data_mods` (`:52`); `spawn_brokerd()` `:236` → `enable_modules=tractor_kwargs.pop('enable_modules')`; `broker_init()` `:184` reads `getattr(brokermod, '_brokerd_mods', getattr(brokermod, '__enable_modules__', []))`. Resulting brokerd enable set has no `piker.data.*` at all.
-2. Fail-fast ep validation via Stage-0 `validate.get_eps()`: `broker_init` raises a clear error when `get_eps(mod, 'brokerd')` is empty (e.g. "kucoin is datad-only — use paper mode"); `datad_init` warns analogously.
-3. ib client-id mitigation in `load_aio_clients()` (`ib/api.py:~1316`): role-based offset when `client_id` is the 6116 default (e.g. `+16` when `'datad' in tractor.current_actor().name`), optionally configurable via `brokers.toml` keys.
-4. Docs/comment sweep: resolve `brokers/_daemon.py:62` TODO, `piker/cli/__init__.py:253` TODO, daemon list in `piker/service/__init__.py:21` docstring.
-
-**Gate**: full suite; audit greps clean: `grep -rn maybe_spawn_brokerd piker/` hits only `clearing/_ems.py`, `service/__init__.py`, `brokers/_daemon.py`; no spawn-path `'brokerd'` literals left in `piker/data`, `piker/ui`, `piker/brokers/cli.py`.
-

-## Risk register
-
-| Risk | Sev | Mitigation |
-|---|---|---|
-| ib: `datad.ib` + `brokerd.ib` both connect to TWS/gw; `client_id=6116` collision burns `connect_timeout` retries | High (live ib only) | Stage 4 role-based id offset; both daemons inherit `infect_asyncio` via `_spawn_kwargs` copy in both init fns |
-| `piker ledger` ad-hoc actor path silently broken by signature change | Med | `portal:` override kept on `open_brokerd_dialog` (Stage 2); explicit smoke test |
-| datad-only backends (kucoin/deribit) → useless brokerd spawn | Low | already covered: `open_brokerd_dialog` forces `exec_mode='paper'` when no trades ep (`_ems.py:413-417`) BEFORE the lazy spawn; Stage 4 fail-fast |
-| brokerd in-process symbology/ledger needs (ib `broker.py` imports `.symbols`; kraken uses `stream_messages`) | None | verified pure in-process imports; `enable_modules` gates RPC only |
-| paper-mode test asserts brokerd spawns (`test_services.py:237`) | Low | Stage 3 deliberately inverts it |
-| doubled per-broker clients (HTTP/WS, symcache loads) | Low | each actor already opens its own WS today; symcache is disk-read-mostly |
-
-## Verification (per stage gates above, plus end-to-end)
-
-- `pytest tests/test_services.py tests/test_feeds.py tests/test_ems.py` at every stage (kraken/binance public endpoints, no creds needed).
-- Manual smoke matrix post-Stage-3: `pikerd -l info` + `piker chart btcusdt.spot.binance` → `piker services` shows `datad.binance`, no brokerd; submit paper order → `paperboi.binance` appears, still no brokerd; symbol search; `piker ledger <broker>.paper`.
-- If ib creds/gateway available: live ib chart + small live order to exercise dual-actor client-id path (Stage 4).
-
-## Critical files
-
-- **new** `piker/data/_daemon.py` — all datad machinery
-- `piker/brokers/_daemon.py` — slimmed brokerd fixture/init/spawn
-- `piker/data/feed.py` — spawn cutover + actor-name assert
-- `piker/clearing/_ems.py` — emsd lazy brokerd spawn (`open_brokerd_dialog`, `Router`)
-- `piker/service/_actor_runtime.py`, `piker/service/__init__.py` — root mods + re-exports
-- `piker/data/validate.py` — `get_eps()` helper
-- backend `__init__.py`s (kraken/binance/deribit/ib) — `_datad_mods`/`_brokerd_mods`
-- `piker/accounting/cli.py` — keyword-form dialog call
-- `tests/test_services.py` — inverted + new assertions

-# OpenCode Integration
-
-[OpenCode](https://opencode.ai/) discovers provider-neutral skills
-directly from `.agents/skills/` and pre-migration piker skills from
-`.claude/skills/`. There is no second copy of each skill to keep in
-sync.
-
-## Available Skills
-
-| Skill | Activation | Specialization |
-|-------|------------|----------------|
-| `commit-msg` | `/commit-msg` or explicit request | Piker commit-message style and artifacts |
-| `piker-clearing-expert` | automatic | Clearing, order-control, and accounting invariants |
-| `piker-conc-expert` | automatic | `tractor` actor topology, RPC, and cancellation |
-| `piker-profiling` | automatic | Cross-actor `Profiler` instrumentation |
-| `piker-slang` | automatic | Project communication style |
-| `py-codestyle` | automatic | Python source conventions |
-| `pyqtgraph-optimization` | automatic | Batched Qt graphics rendering |
-| `timeseries-optimization` | automatic | NumPy and Polars timeseries performance |
-
-OpenCode's project command lives at
-`.opencode/commands/commit-msg.md`. It delegates to the
-shared `commit-msg` skill and only supplies command
-arguments; workflow logic remains in the skill.
-
-A user-local skill with the same name may override a repo
-skill. Treat `opencode debug skill` as authoritative when
-diagnosing which source is active.
-
-## Verify Discovery
-
-From the repository root:
-
-```console
-opencode debug skill
-opencode debug config
-```
-
-`opencode debug skill` should list the piker skills from
-the project checkout. Restart OpenCode after changing a
-skill or command because configuration-time files are not
-hot-reloaded into an active session.
-
-## Portability Rules
-
-- Use only portable Agent Skills frontmatter in shared
-  `SKILL.md` files.
-- Keep harness-specific command syntax under
-  `.opencode/commands/`.
-- Detect the active harness and model at runtime; do not
-  hardcode Claude Code attribution in shared workflows.
-- Keep supporting references beside each shared skill so
-  relative links resolve in every harness.
-- Put new provider-neutral bundles under `.agents/skills/`; use
-  relative provider links only when a harness requires one.

-Proximate driver for THIS commit: during the approved
-plan's stage-0 test gate the agent discovered test
-subactors were writing into the user's REAL
-`~/.config/piker/accounting/` files (a bogus paper fill
-landed in `account.kraken.paper.toml`) because the old
-test-dir override in `config.get_app_dir()` was
-commented out and could never work in spawned
-subactors anyway. Fix applied autonomously under the
-approved plan; no explicit per-fix user prompt.
-
-## Response summary
-
-Restore `pytest` config-dir isolation by resolving the
-per-test tmp dir lazily (at conf-path access time) from
-`tractor` runtime-vars, which propagate down the actor
-tree; route all conf-path derivation through
-`config.get_conf_dir()` so the override is effective in
-every (sub)actor.
-
-## Files changed
-
-- `piker/config.py` — add `_maybe_use_test_dir()`;
-  hook in `get_conf_dir()`; route `get_conf_path()` +
-  `load()` mkdir through it

-  via `config.get_conf_dir()` (not the global)

-Key diagnostic reasoning (verbatim from session):
-
-- the "DID NOT RAISE ContextCancelled" failure: in this
-  test the client actor IS pikerd (in-proc), and
-  current `tractor` main absorbs a `ContextCancelled`
-  whose canceller is your own actor — self-requested
-  cancels now exit cleanly instead of raising; the
-  'sigint' variant propagates a bare collapsed
-  `KeyboardInterrupt` rather than a
-  `BaseExceptionGroup`.
-- the hard-coded `trio.fail_after(9)` startup budget is
-  marginal — full stack boot (pikerd -> emsd ->
-  brokerd.kraken -> paperboi + live kraken symbology
-  fetch) occasionally exceeds 9s -> bumped to 19s.
-- `RemoteActorError.type` -> `.boxed_type`;
-  `Position.size` -> `.cumsize` (the paper engine
-  populates `BrokerdPosition.size` from `pp.cumsize`).
-- overlap survey (user-requested): all of the
-  `repair_tests` branch commits are already in this
-  stack's ancestry; this commit finishes that branch's
-  port mission (its f4c4f1e2 fixed `conftest.py`'s
-  `arbiter_sockaddr` usage; this fixes the remaining
-  `test_services.py` + `check_for_service()` sites).

-approved plan's "stage 0" prep. Plan-shaping user
-decisions captured via in-session Q&A:
-
-- `datad.<broker>` topology: sibling of
-  `brokerd.<broker>` under `pikerd` (vs. child
-  subactor).
-- migration: hard cutover, staged by layer (no
-  dual-mode runtime flag).
-- post-split `brokerd` scope: trading-only +
-  EMS-lazy-spawned (charts/CLI never touch it).
-
-## Response summary
-
-Declare per-daemon-kind backend submod groups
-(`_datad_mods`/`_brokerd_mods`) in the split-style
-backends, keyed to the pre-existing
-`piker.data.validate._eps` contract; add a

-Key exploration findings driving the design (from the
-planning phase, 3 parallel explore agents + 1 architect
-agent):
-
-- the codebase already anticipated this split:
-  `validate._eps` groups eps into 'datad' vs 'brokerd'
-  kinds and `ib/__init__.py` already declared
-  `_brokerd_mods`/`_datad_mods`; `brokers/_daemon.py`
-  carried the literal TODO "rename the daemon to datad
-  prolly once we split up broker vs. data tasks into
-  separate actors?".
-- the feared kraken feed<->broker "shared ws state"
-  hazard is mild: `NoBsWs`/`open_autorecon_ws`
-  originate in `piker.data._web_bs` (re-exported via
-  `.kraken.feed`); only `stream_messages` is feed-local
-  and it's a pure parser — in-process imports only,
-  each actor opens its own ws conn.
-- `enable_modules` gates RPC entry, NOT python imports,
-  so backend trading mods may keep importing feed-side
-  helpers in-process post-split.

-Generated symbols + key design decisions:
-
-- `_datad_service_mods: list[str]` — datad-always
-  enabled mods, the data-side successor to the old
-  `piker.brokers._daemon._data_mods` set; kept minimal
-  per the caps-sec model.
-- `_setup_persistent_datad()` — `@tractor.context`
-  lifetime fixture: console-log setup then allocates
-  the actor-global feed bus via
-  `feed.get_feed_bus(brokername, service_nursery)`
-  exactly as the old brokerd fixture did, pinned open
-  with `ctx.started()` + `sleep_forever()`.
-- `datad_init()` — actor name `f'datad.{brokername}'`;
-  copies backend `_spawn_kwargs` (CRITICAL for `ib`'s
-  `infect_asyncio=True`); builds `enable_modules` from
-  `getattr(brokermod, '_datad_mods',
-  getattr(brokermod, '__enable_modules__', []))` as
-  the flat-backend fallback.
-- `spawn_datad()` — `Services.actor_n.start_actor()` +
-  `Services.start_service_task()` exactly mirroring
-  `spawn_brokerd()`; dedup-composes enable mods via
-  `list(dict.fromkeys(...))`.
-- `maybe_spawn_datad()` — wraps `maybe_spawn_daemon(
-  service_name=f'datad.{brokername}', ...)`.

-> `git log -1 -p --follow -- piker/service/__init__.py`
-> `git log -1 -p --follow -- tests/test_services.py`
-
-Design rationale (verbatim from session):
-
-- `_root_modules` must gain `piker.data._daemon` so
-  `pikerd_portal.run(spawn_datad, ...)` resolves in
-  the root.
-- the `Services`-based impl style deliberately mirrors
-  `spawn_brokerd()` so the eventual `tractor.hilevel`
-  `ServiceMngr` port (see the `service_mng_to_tractor`
-  branch's d8c21d44 prep, surfaced by the
-  user-requested branch-overlap survey) lands
-  symmetrically on both spawn fns.
-- mod placement (`piker/data/_daemon.py` vs.
-  generalizing `piker.brokers._daemon`) follows the
-  per-subsystem daemon-mod convention
-  (`.clearing._ems`, `.data._sampling`) and resolves
-  the existing TODO at `brokers/_daemon.py:49` ("move
-  this def to the `.data` subpkg").

-`(brokermod, exec_mode, fqme=None, portal=None,
-loglevel=None)` with an inner `@acm
-acquire_live_portal()` that yields the caller-provided
-`portal` override (the `piker ledger` path) else

-
-> `git log -1 -p --follow -- piker/accounting/cli.py`
-
-Key analysis (verbatim from session):
-
-- `feed.portals` had exactly ONE trading consumer:
-  `piker/clearing/_ems.py:671` (`portal =
-  feed.portals[brokermod]`) — the single coupling
-  forcing feed + trading into one actor.
-- `piker ledger` (`accounting/cli.py:100-157`) is a
-  hidden consumer: it calls `broker_init()` directly,
-  spawns its own ad-hoc actor and passes the portal
-  positionally — the new signature must keep an
-  explicit `portal:` override param for this path.
-- stage sequencing: clearing decouple lands BEFORE the
-  feed cutover, otherwise `feed.portals` would hand
-  emsd a `datad` portal and live `open_trade_dialog`
-  RPC would fail.

-(disjoint from `brokerd`'s linear `client_id + i`
-retry range), other non-`brokerd` (ad-hoc test/cli)

-## Prompt
-
-The session-initiating instruction, verbatim (this doc
-IS its "mega detailed plan" deliverable):
-
-> ok i want you to become the distributed runtime and
-> concurrency expert for this project - namely acquire
-> a deep understanding of tractor and how it's used.
-> then i want you to atttempt to factor our current
-> brokerd service daemon into 2 daemons:
->
-> - a brokerd which only hosts live/paper trading
->   endoint tasks as defined namely within all
->   piker/brokers/<backend>/broker.py mods
-> - a new `datad` subdaemon which in a separate
->   subactor serves all the data feed service tasks
->   namely delivered by endpoints in
->   piker/brokers/<backend>/feed.py (or similar for
->   less mature backends) and as more rigorously
->   defined by the validation machinery in
->   piker.data.validate.
->
-> give me a mega detailed plan on how to approach
-> this, and a staged approach for the implementation.
-
-Plan-shaping user decisions (in-session Q&A): sibling
-topology under `pikerd`; hard cutover staged by layer;
-trading-only EMS-lazy-spawned `brokerd`. The human
-staged the doc copy into `ai/claude-code/plans/` and
-requested this commit after the 7 implementation
-commits landed.
-
-## Response summary
-
-The staged design doc for the `brokerd` -> (`datad` +
-`brokerd`) split: context, target supervision topology,
-load-bearing verified facts, per-stage file-level
-changes with gates, risk register and an end-to-end
-verification matrix. Produced via 3 parallel explore
-agents + 1 architect agent + human Q&A before any code
-was written; all 7 implementation commits in this
-branch reference its stages in their provenance
-entries.

-## Implementation deviation log
-
-Where the landed 7-commit series differs from the plan
-as written (recorded for reviewer transparency; the
-plan doc is committed unmodified):
-
-1. Commit ordering: the `pytest` config-dir isolation
-   fix lands BEFORE the `tractor`-API drift port. The
-   plan's stage gates assumed a runnable+isolated test
-   baseline; per-commit gating exposed that without
-   isolation the paper-EMS test reads the user's real
-   (polluted) `account.kraken.paper.toml` and reddens.
-2. The plan's "stage 0: full pytest green" gate
-   required first repairing pre-existing branch
-   breakage vs `tractor` git `main` (boot
-   `AttributeError`, stale discovery/exc/position
-   APIs) — that repair became its own commit
-   ("Port service+tests to latest `tractor` APIs")
-   rather than plan-stage work.
-3. Stage-4 fail-fast placement: the plan said
-   `broker_init()` raises on brokerd-ep-less backends;
-   implementation moved the raise to `spawn_brokerd()`
-   since `piker ledger` calls `broker_init()` directly
-   even for paper accounts on datad-only backends.
-4. `brokers/_daemon.py` change grouping: the
-   import-cleanup hunks (`exceptiongroup`, `_FeedsBus`
-   type-only import) landed with the caps-sec slim
-   commit instead of the fixture-slim commit, keeping
-   each intermediate tree import-clean without
-   sub-hunk surgery.
-
-Also of record: the plan's "Verification" matrix was
-executed as written (per-suite gates each stage, the
-headless datad-feed smoke, the kucoin fail-fast unit
-check); the known pre-existing ~50% second-runtime-boot
-test wedge was characterized and excluded as a
-regression via revert-testing.

-## Prompt
-
-User bug report from live `ib` testing of the
-(datad|brokerd)-split branch:
-
-> ok doing some testing and noticing live orders do not
-> work otb, pikerd show this on live submission,
-> [pdb traceback: `RuntimeError("Can not order
-> {symbol}, no live feed?")` at `ib/api.py:1152`
-> `submit_limit()` with `self._contracts == {}` in the
-> `brokerd.ib` actor + a `TrioTaskExited` teardown
-> cascade]
-
-Follow-up user direction fixing the design intent:
-
-> i think the main thing here is that [brokerd] should
-> be able to always submit orders without a live feed
-> being up and registered in the same subactor right?
-
-## Response summary
-
-Root cause: pre-split the feed code populated the
-actor-local `Client._contracts` cache (via
-`get_mkt_info()` writing `mkt.bs_fqme` keys) in the
-SAME process as order submission; post-split the
-trading actor's client is never warmed. Fix: lazily
-qualify + cache the contract per order request in
-`handle_order_requests()` by running the same
-`get_mkt_info(fqme, proxy=...)` ep the feed side uses,
-plus per-order error relay (`BrokerdError`) so one bad
-submission can't crash the whole trades dialog (the
-`TrioTaskExited` storm was teardown cascade from the
-original raise).
-
-## Files changed
-
-- `piker/brokers/ib/broker.py` — thread `proxies` into
-  `handle_order_requests()`; lazy contract qualify on
-  cache-miss; guard `submit_limit()` w/ `BrokerdError`
-  relay; uncomment the (anticipatory) `get_mkt_info`
-  import
-- `piker/brokers/ib/api.py` — fix the non-f-string
-  raise msg + document the new qualification contract
-
-## Human edits
-
-None — committed as generated. Live `ib` order retest
-performed by the human post-commit.

-Key diagnostic chain (from session):
-
-- pdb showed `Client._contracts == {}` inside
-  `brokerd.ib`'s `submit_limit()`; the cache has
-  exactly TWO write sites: `Client.find_contracts()`
-  (api.py, keys `f'{sym}.{exch}.ib'`) and
-  `symbols.get_mkt_info()` (key `mkt.bs_fqme`, eg.
-  'nvda.nasdaq' — NO `.ib` suffix).
-- `BrokerdOrder.symbol` arrives as the bs_fqme form
-  ('nvda.nasdaq') so ONLY the `get_mkt_info()` write
-  site produces the key `submit_limit()` reads —
-  ie. pre-split it was the feed's in-proc
-  `get_mkt_info(sym, proxy=proxy)` call keeping orders
-  working, NOT `find_contracts()`.
-- the existing TODO at `symbols.py:642-644` literally
-  predicted this: "this is going to be problematic
-  if/when we split out the datad vs. brokerd actors
-  since the mktmap lookup table will now be
-  inaccessible.."
-- instance identity verified: `proxy._aio_ns` IS the
-  same `Client` obj as `_accounts2clients[account]`
-  (both sourced from the `load_aio_clients()` cache via
-  `open_client_proxies()`), so a brokerd-side
-  `get_mkt_info(fqme, proxy=proxies[account])` warms
-  exactly the dict `submit_limit()` reads. It also
-  populates `client._cons2mkts` which the
-  position-audit path (`broker.py` backup-table code)
-  needs in this actor anyway.
-- the `TrioTaskExited` storm in the user's log
-  (`recv_trade_updates`, `open_aio_client_method_relay`
-  aio tasks) is teardown cascade: the raise crashed
-  `handle_order_requests` -> nursery teardown ripped
-  the trio sides of still-running aio relay tasks.
-  Hence the added per-order try/except ->
-  `BrokerdError` relay hardening so a single bad
-  submission degrades to an EMS error msg instead of
-  killing the backend's entire order-ctl dialog.
-
-Verification: `tests/test_services.py` (5 passed) +

-## Policy
-
-Prompt logging follows the
-[NLNet generative AI policy][nlnet-ai].
-All substantive AI contributions are logged

-
-Entries are created by the `/prompt-io` skill
-or automatically via `/commit-msg` integration.
-
-Each commit carrying AI-generated changes links
-to its provenance entry via a `Prompt-IO:`
-commit-msg trailer; entries use "diff-ref mode"
-(pointers into `git log -p` instead of verbatim
-code copies) to avoid duplicating committed

-## Prompt
-
-The human asked to capture all ongoing Trend Calculus/Jev follow-ups
-in Taken, supplied the federated_project_stores worktree, and then
-requested a complete commit plan for that branch. They confirmed
-that workflow configuration already exists on moar_ai_skillz and
-asked why the earlier trend package duplicated it.
-
-## Response summary
-
-Resolved the registered Piker corpus and unique structural parent.
-Used Taken's guarded whole-document save to append six identified
-TODO tasks and 24 unchecked items. Preserved every prior byte,
-existing state, property and order. Linked the existing FSP review
-instead of duplicating it and kept annotation IPC follow-ups with
-the existing task. Recorded known harness/worktree/branch provenance.
-
-Corrected only the new prototype-review task's prose to require the
-existing f148fbcc/moar_ai_skillz workflow dependency and regenerate
-six Trend Calculus behavior boundaries. No task marker was changed.
-Added a whitespace attribute limited to .taken Org documents so the
-required final empty subtree separator passes standard Git checks.
-No other workflow configuration is included in this commit package.
-
-## Verification
-
-Taken lint previously passed on the saved corpus and standard Git
-whitespace checks pass with the path-scoped Org attribute. Saved
-bytes were checked against the guarded candidate; all original
-corpus content and state markers are intact. The commit package
-selects a read-only lint against its exact boundary store, with
-application tests excluded for this data-only change. That check
-remains pending until package execution; no earlier whole-worktree
-result is claimed as an exact-boundary reusable pass.
-
-## Human edits
-
-The human authorized loading the registered store and requested
-planning, not execution. Their workflow-history correction directly
-changed the new review task. Existing human tasks remain unaccepted;
-no commits, pushes, rebases, mainlining or existing-state changes
-were performed. The main checkout's staged content was preserved.

-## Human instruction (verbatim)
-
-after this pass i want us to start loading our taken store with all the ongoing / todos/ follow ups anyway - we can hash it all out there.
-
-it's on another unmerged wkt we have to mainline, not sure what the
-best stopgap for that is rn but the existing taken is here,
-wkt/federated_project_stores
-
-can we do a $commit-plan for that wkt branch with this stuff then as
-well? i'm going to try and get it landed to main asap so we can start
-always updating it directly from our working branch/wkt.
-
-uhh isn't this already in f148fbcc and the moar_ai_skillz branch??
-
-## Captured assistant output (verbatim)
-
-The style pass and seven-commit package are finished. I added
-six follow-up tasks with 24 unchecked items to the registered
-Taken corpus and verified that all prior content is unchanged.
-Taken lint passes.
-
-You’re right: the three `.ai` files are byte-for-byte identical
-to `f148fbcc` on `moar_ai_skillz`. That commit isn’t in this
-checkout or local `main` yet, but I should have treated it as
-an existing branch dependency, not proposed a duplicate commit.
-
-I’m withdrawing that workflow step from the Trend Calculus plan.
-Those files are now staged here; I’ll leave your index untouched.

-
-> `git diff HEAD~1..HEAD -- .gitattributes`

-These pointers name the completed one-boundary commit after human
-review/execution. The prepared package captures the pending delta.
-Six identified tasks retain all existing states and record prototype
-review, live Jev qualification, service wiring, Pine parity, chart
-qualification and native subsecond source work. A narrow Org
-attribute permits Taken's required blank separator at EOF while
-retaining other whitespace diagnostics. No Git commit ran.

-Added deterministic analysis regressions and corrected normalization
-so sorting and duplicate resolution precede derived-column

-child processes to the reviewed worktree, capture checksum-bound phase
-evidence, safely seed and clear test history, and compare lifecycle
-preservation.
-
-The workflow rejects path traversal, pre-existing symlinks, output

-
-The implementation focused on the exact failure boundary. It does not

-Generated `_shm_period_and_invalid_count()` and integrated its result in

-The user requested an evaluation and possible update of `piker store`,
-including immediate help output when a group or endpoint is invoked with
-no arguments. The user also proposed eventual optional `fzf` selection for
-`anal` and `ldshm`, and authorized aggregating the recent time-series and
-SHM debugging work into CLI endpoints. After reviewing three scopes, the
-user selected the recommended safe foundation rather than implementing
-interactive fuzzy selection or changing mutation defaults immediately.
-
-> `git diff HEAD~1..HEAD -- piker/storage/cli.py`
-
-Generated no-argument help behavior for the `store` group and every
-endpoint. Added read-only `series` and `shm` commands, JSON and Rich output,
-exact `--shm-name` plumbing, SHM cadence/invalid/order/gap summaries, and
-safe corrupt-epoch formatting. Fixed existing `ldshm` no-write/no-reload
-control flow and no-match debugger behavior.
-
-> `git diff HEAD~1..HEAD -- piker/storage/nativedb.py`
-
-Generated canonical `NativeSeriesRef` parsing and deterministic listing.
-Changed the internal index to preserve `(fqme, period)` identities while
-keeping unique-FQME compatibility listing and cardinality. Hardened
-malformed, sidecar, Unicode-period, symlink, and traversal handling.
-
-> `git diff HEAD~1..HEAD -- piker/tsp/_history.py`
-
-Generated exact `ShmBufferRef` parsing and stable discovery, replacing
-unsafe substring globbing. Added dtype resolution that mirrors history
-allocation, exact-ref attachment, disappearance handling, and optional
-exact-name iteration.
-
-> `git diff HEAD~1..HEAD -- piker/data/_sharedmem.py`
-
-Generated attach-only SHM access which never creates a segment when a
-discovered object disappears.
-
-> `git diff HEAD~1..HEAD -- piker/tsp/__init__.py`
-
-Exported selector-ready SHM identity, parsing, listing, and dtype helpers.
-
-> `git diff HEAD~1..HEAD -- tests/test_store_cli.py`
-
-Generated command-level help, exact durable-series JSON, read-only SHM JSON,
-and unknown exact-name regressions.
-
-> `git diff HEAD~1..HEAD -- tests/test_ldshm.py`
-
-Generated SHM identity, summary, ordering, dtype, forged-name, disabled
-mutation-flag, and gap-markup regressions.
-
-> `git diff HEAD~1..HEAD -- tests/test_storage_nativedb.py`
-
-Generated compound index, canonical parser, malformed filename, and dotted
-FQME regressions.
-
-> `git diff HEAD~1..HEAD -- docs/manual_backfill_qualification.rst`
-
-Documented `store series` and `store shm` as separate read-only durable and
-live-memory triage layers.
-
-> `git diff HEAD~1..HEAD -- .claude/skills/run-tests/test-harness-reference.md`
-
-Registered the deterministic storage CLI UX target and mapping.

-
-Real `piker store` and `piker store audit` invocations printed complete
-help without `--help`, exiting with Click's normal no-args help status 2.
-`git diff --check` passed. Ruff was unavailable in the existing worktree
-environment.
-
-Adversarial review drove fixes for provider dtype reconstruction, observed
-versus expected cadence, exact SHM grammar, discovery races, Typer direct
-defaults, malformed NativeDB periods, compound cardinality compatibility,
-undefined `ldshm` reload payloads, no-match debugger hangs, ordering
-corruption reporting, and dtype precedence. Final review found no issues.
-
-Optional external `fzf` or built-in numbered selection remains deferred.
-The exact series and SHM identities added here are the intended foundation
-for that later patch.

-## Prompt
-
-Make `piker store ls` default to all NativeDB series as a compact counterpart
-to detailed `series`, with sensible no-flag output and a visible help
-description. Consolidate SHM inspection and repair under canonical `shm`,
-because attachment to volatile segments is implied, and make inspection the
-safe default while retaining explicit persistence and reload controls.
-
-## Response summary
-
-Replaced backend-oriented `ls` with compact NativeDB discovery and made both
-listing commands default to all series. Consolidated SHM behavior under a
-read-only-by-default `shm` command, guarded explicit repair options, updated
-executable references and docs, and added command regressions.
-
-## Files changed
-
-- `piker/storage/cli.py` - listing defaults and unified SHM command modes.
-- `tests/test_store_cli.py` - listing, help, and SHM mode regressions.
-- `tests/test_ldshm.py` - explicit persistence-path regressions.
-- `docs/manual_backfill_qualification.rst` - revised safe CLI workflow.
-- `snippets/claude_debug_helper.py` - explicit SHM persistence commands.
-- `.claude/skills/run-tests/test-harness-reference.md` - safety and test map.
-- `.claude/skills/piker-slang/examples.md` - canonical command example.

-The user requested command-surface refinements after reviewing the new
-storage CLI. Bare `ls` should default to all series and act as a compact
-form of detailed `series`; commands should produce sensible default output
-without requiring trigger flags; and `ls` needed a parent-help description.
-The user first proposed folding read-only SHM inspection into `ldshm -r`,
-then clarified that `shm` is the better canonical command because attaching
-to volatile segments is implied by the resource name.
-
-The resulting design uses `piker store ls` as a compact NativeDB FQME and
-period view, while `piker store series` reports each exact sub-series with
-size and path details. Both default to all records and accept an optional
-FQME substring.
-
-`piker store shm FQME` is read-only by default. Persistence and reload enter
-the prior repair workflow only through explicit `--write-parquet` and
-`--reload-parquet-to-shm` flags. Reload requires persistence, and read-only
-formatting flags are rejected in repair mode instead of being ignored.
-
-> `git diff HEAD~1..HEAD -- piker/storage/cli.py`
-
-Generated shared NativeDB payload collection, compact and detailed output,
-numeric period ordering, default-all semantics, the canonical `shm` command,
-safe mode dispatch, explicit repair validation, and debugger propagation in
-read-only mode.
-
-> `git diff HEAD~1..HEAD -- tests/test_store_cli.py`
-
-Generated regressions for no-flag listing, parent-help descriptions, numeric
-period display, default read-only SHM JSON, reload dependencies, and repair
-versus read-only option conflicts.
-
-> `git diff HEAD~1..HEAD -- tests/test_ldshm.py`
-
-Adjusted persistence regressions for the renamed command and explicit repair
-entry while preserving the historical failure rationale.
-
-> `git diff HEAD~1..HEAD -- docs/manual_backfill_qualification.rst`
-
-Documented compact versus detailed NativeDB discovery, default read-only SHM
-inspection, and the explicitly mutating repair invocation.

-Real command-help rendering was checked for the parent group, `ls`, `series`,
-and `shm`. Real read-only `ls` and `series --json` output was also exercised
-against the configured NativeDB. `git diff --check` passed.
-
-Adversarial review identified and drove fixes for lexicographic period
-ordering, stale runbook safety wording, ignored mode-specific options, and an
-explicit-default `--max-gaps 10` validation bypass. Final review found no
-remaining issues. Real OS-backed SHM attachment and successful repair/reload
-remain integration-level validation concerns.
