+# Security ID handling in `sparkd`
+
+This document traces how security identifiers are created, translated, persisted,
+indexed, and published by the `sparkd` market-data paths. It focuses on the
+legacy CME MDP3/OnixS pipeline and the newer generalized market-data pipeline.
+
+## Executive summary
+
+`sparkd` uses two identifiers that must not be confused:
+
+| Identifier | Meaning | Typical field | Lifetime |
+|---|---|---|---|
+| Exchange/feed ID | The venue's identifier used to route incoming definitions, books, and trades | `FixedSecurity::numeric_id`, `ExchangeKey`, or `domain::Security::security_common.exchange_sec_id` | Feed/session-specific unless the source guarantees stability |
+| Spark security key | Spark's internal non-zero identifier used in shared memory, APIs, orders, positions, and downstream services | `FixedSecurity::key`, `api::Security::id()`, `SecurityKey`; historically also called `security_id` | Intended to be stable across restarts |
+
+`invalid_security_key` is `0`; a security with key `0` is not yet publicly
+discoverable through the shared-memory consumer path.
+
+The two principal paths differ:
+
+- **MDP3/OnixS:** the definition callback sets only the CME ID in
+  `numeric_id`. `MDProducer::add_security()` allocates the shared-memory entry
+  with key `0`. `SecurityIDRecorder`, driven by a 200 ms dispatcher timer,
+  resolves or inserts a stable key in `key_ids.sqlite`; its callback finally
+  calls `MDProducerHandle::set_key()`.
+- **Generalized/newer pipeline:** `GeneralMarketDataListener::on_securities()`
+  currently uses the ID already present on the incoming domain security
+  (`use_given_sec_key == true`). Live adapters normally obtain that ID
+  synchronously from `IDGenerator` first. `_copy_security_common()` then copies
+  it to both `FixedSecurity::key` and `numeric_id`, so
+  `MDProducer::add_security()` publishes it synchronously. Only the listener's
+  own fallback `IDGenerator` call is bypassed by the current constant.

+## Data-flow charts
+
+The sequence diagrams above emphasize timing and thread transitions. These
+flowcharts emphasize which identifier is carried through each representation
+and where data is retained.

+
+The CME index is usable before the Spark key is assigned, so feed updates can
+reach the internal handle while the security is still hidden from consumers.
+The persistent rowid crosses the publication boundary only at `set_key()`.

+
+```
+
+In the normal newer live path, persistence occurs before the definition enters
+the generalized listener. The DB call therefore adds synchronous adapter-side
+latency, but publication needs no later timer. Most adapters use an in-memory
+map for subsequent events; the dotted Python path is the documented exception.
+
+## The publication boundary
+
+`MDProducerHandle::set_key()` is the definitive publication point for the
+legacy shared-memory representation. Its write ordering is intentional:
+
+1. Write the key into the hot book entry (`HotEntry` or `HotDepthEntry`).
+2. Write the key into the cold security entry.
+3. Increment the cold header's public `security_count`.
+
+The cold security key is written last because consumers treat a non-zero cold
+key as visibility. At that moment the corresponding hot entry must already be
+addressable. `set_key()` only permits the transition from `0` to one key; it is
+not a key-update mechanism.
+
+## Identifier representations
+
+The names are historically inconsistent. In particular, many protobuf fields
+named `security_id` contain the **Spark key**, not the exchange's ID.
+
+| Layer | Exchange/feed identifier | Spark identifier |
+|---|---|---|
+| MDP3 wire/OnixS | `securityId()` | not present |
+| Legacy fixed security | `FixedSecurity::numeric_id` (`uint64_t`) | `FixedSecurity::key` / `security_key` (`uint32_t`) |
+| Legacy API security | venue-specific `exchange_id` | top-level `Security.id()` |
+| New domain model | `SecurityCommon::exchange_sec_id` (string) is descriptive; `SecurityCommon::id` is also used to correlate source events | `domain::SecurityID` (`uint64_t`), currently copied into the Spark key |
+| Shared-memory hot book | none | `HotEntry::key` or `HotDepthEntry::key` |
+| Shared-memory cold metadata | `FixedSecurity::numeric_id` | `FixedSecurity::key` |
+| CME runtime lookup | `CMESecurityIndex` key | `SecurityData::handle.key()` |
+| General runtime lookup | incoming/canonical `domain::SecurityID` | `GeneralSecurityIndex` key and `handle.key()` (currently the same value) |
+
+The generalized model declares `domain::SecurityID` as 64-bit, but the legacy
+shared-memory `security_key` remains 32-bit. `_copy_security_common()` assigns a
+64-bit value to both `numeric_id` and the 32-bit `key`. This is safe only while
+allocated IDs fit in 32 bits; unlike the legacy lookup path, this assignment has
+no explicit checked conversion.
+
+## Which parts use exchange IDs, descriptors, or Spark security IDs?
+
+The three identifier classes serve different jobs:
+
+- **Exchange/external ID:** routes data inside a venue or vendor feed adapter.
+- **Descriptor/natural key:** recognizes a definition logically at the
+  persistence, discovery, or human-facing boundary.
+- **Spark security ID/key:** joins the instrument to books, orders, fills,
+  positions, and services after publication.
+
+The core downstream system does not repeatedly identify a security from its
+description. The description is primarily used to obtain a Spark key; after
+that boundary, most joins use the numeric Spark key.
+
+### Component-level usage matrix
+
+| Component or data path | Exchange/external ID | Descriptor or name | Spark security ID/key |
+|---|---|---|---|
+| CME MDP3 definition decoder | Reads `securityId()` and stores it in `FixedSecurity::numeric_id` | Copies definition symbol/tag 55 into `security_desc` | Leaves `FixedSecurity::key` at `0` initially |
+| `CMESecurityIndex` | Primary map key; CME ID resolves to a handle | Not used for update routing | Returns `handle.key()` when the Spark key has been assigned |
+| MDP3 books, trades, status, statistics, and RFQs | Incoming CME ID selects the handle through `CMESecurityIndex` | Not used to locate each update | The selected handle writes keyed shared-memory/trade data after publication |
+| MDP3 spread definitions | Each leg initially contains `legSecurityId()` as `exchange_key` | Parent `security_desc` identifies the spread's DB row | Each leg's Spark key and then the parent Spark key must be resolved before publication |
+| Legacy ICE OnixS | Uses ICE `marketId` as `numeric_id` and index key | ICE security description becomes the logical lookup name | Uses the same recorder-assigned Spark key pattern as MDP3 |
+| `SecurityIDRecorder` | Does not allocate from the external ID | Uses `(venue, security type, securities::descriptor())` to find/create a row | Treats the SQLite rowid as the resulting Spark key |
+| Native generalized adapters | Use exchange strings/numeric IDs to parse definitions and correlate updates | Usually pass a description or exchange instrument name to `IDGenerator` | Put the returned ID into `SecurityCommon::id` and later events |
+| Databento adapter | Uses `msg.hd.instrument_id` for feed correlation and its in-memory map | Uses the decimal instrument ID string—not the human description—as the `IDGenerator` name | Caches `instrument_id -> domain::SecurityID` and places that ID on books/trades |
+| Python bridge | Reads `exchange_security_id` from definitions, books, and trades | Uses that external-ID string as the `IDGenerator` name | Resolves it to `domain::SecurityID`; currently performs this lookup for every event |
+| `IDGenerator` | Does not interpret whether `name` came from an exchange ID | Uses exactly `(venue, type, caller-supplied name)` | Returns the SQLite rowid as a 64-bit ID |
+| `GeneralMarketDataListener` | Does not route on `exchange_sec_id` directly | Copies `sec.desc()` into fixed metadata; its disabled fallback allocator would use `sec.desc()` | Uses incoming `SecurityCommon::id`, maps events through `cc_sec_id_map`, and copies the value into both `key` and `numeric_id` |
+| `GeneralSecurityIndex` | No separate external-ID concept in the current use-given path | Not used | Maps the generalized ID/Spark key to `MDProducerHandle` |
+| `MDProducer` / shared memory | Retains `numeric_id`; in legacy feeds this is the exchange ID, but in the generalized path it is currently the Spark ID | Stores `security_desc` in the cold definition | Uses the key in hot/cold entries; non-zero key is the visibility boundary |
+| `MDConsumer` | Not normally used to find live books | Can enumerate/filter converted security definitions | Finds handles and book data by `security_key` |
+| `SecurityCache` / `securities.sqlite` | Preserves venue-specific exchange data inside the serialized security blob | Maintains descriptor/name lookup indexes and supports venue/type/name queries | Primary persisted definition key is `api::Security.id()` |
+| MBO processor and MBO service | May retain exchange **order** IDs, which are separate from security exchange IDs | Not used to find the instrument | Indexes snapshots and requests by `SecurityKey`; MBO protobuf `security_id` means Spark key |
+| Order manager and algorithms | Execution gateways eventually use venue-specific fields from the resolved security to encode orders | Descriptions appear in logs and errors, not as the primary join | Order definitions, subscriptions, book events, native orders, spread legs, and fills use `security_key` / `Security.id()` |
+| Position, PNL, and risk services | Not used as their position join | May resolve metadata for display/reporting | Positions, fills, overrides, and PNL handles are keyed by Spark security ID |
+| Relay and market-data recordings | Serialized security definitions may preserve venue exchange IDs | Preserve full descriptors in recorded definitions | Books, updates, trades, and replay correlation preserve the recorded Spark key |
+| Synthetic security service | No venue exchange ID; synthetics use `VENUE_BTS` | Synthetic name is the recorder's logical descriptor | Recorder assigns the SQLite rowid and synthetic metadata is keyed by it |
+
+### Exchange/external IDs: where they stop
+
+In MDP3 the separation is explicit:
+
+```text
+CME SecurityID
+    -> FixedSecurity.numeric_id
+    -> CMESecurityIndex lookup
+    -> MDProducerHandle
+    -> Spark security_key for downstream publication
+```
+
+The external CME ID continues to route feed messages but does not become the
+order/position key. This permits the same downstream Spark key to survive a
+restart as long as the logical descriptor mapping remains in
+`key_ids.sqlite`, even if the feed must rediscover the CME routing ID.
+
+The generalized path collapses more of these roles:
+
+```text
+exchange/vendor identity
+    -> adapter calls IDGenerator
+    -> domain::SecurityID
+    -> FixedSecurity.key and FixedSecurity.numeric_id
+    -> GeneralSecurityIndex and downstream Spark key
+```
+
+`SecurityCommon::exchange_sec_id` may still contain the original textual
+external identifier, but `GeneralMarketDataListener` does not use it to route
+events and does not put it in `numeric_id`. The adapter must translate later
+events to `domain::SecurityID` before invoking the listener.
+
+### Descriptor/name users
+
+Descriptors are used in three main places:
+
+1. **Key allocation:** `SecurityIDRecorder` uses the legacy venue-specific
+   descriptor, while `IDGenerator` uses its caller-provided `name`.
+2. **Definition lookup and discovery:** `SecurityCache` supports
+   venue/type/name lookup; symbol filters and administrative tools use security
+   metadata to select or display instruments.
+3. **Diagnostics:** logs include symbols and descriptions so humans can
+   understand a numeric key.
+
+Descriptions generally do not drive the high-rate book, trade, order, fill, or
+position paths. Those paths use numeric IDs after definition resolution.
+
+It is important that “descriptor” does not mean one universal canonical field:
+
+- Legacy CME uses Globex `security_desc` from tag 55.
+- Many generalized adapters use `sec.desc()` or an exchange instrument name.
+- Databento uses its numeric instrument ID converted to a string.
+- Python uses `exchange_security_id`.
+
+Therefore, two adapters may describe the same economic contract but request
+different logical rows and receive different Spark IDs.
+
+### Spark security-ID users
+
+Once a security is published, its Spark key is the dominant system identifier:
+
+```mermaid
+flowchart LR
+    KEY["Spark security key"] --> SHM["Hot/cold shared memory"]
+    KEY --> MDC["MDConsumer and book subscriptions"]
+    KEY --> MBO["MBO snapshots and queries"]
+    KEY --> OMS["Orders, algorithms, and spread legs"]
+    KEY --> FILLS["Fills and execution records"]
+    KEY --> POS["Positions, PNL, and risk"]
+    KEY --> API["Services and client APIs"]
+    KEY --> REC["Relay and market-data recordings"]
+    KEY --> SECDB["Serialized security definitions"]
+```
+
+Fields named `security_id`, `security_key`, or top-level `Security.id()` in
+these downstream areas almost always mean the Spark key. They should not be
+compared directly with CME `SecurityID`, Databento `instrument_id`, or another
+venue/vendor identifier without going through the relevant adapter/index
+mapping.
+
+## Persistence and allocation
+
+### The authoritative key mapping: `key_ids.sqlite`
+
+Both allocators use `SqliteStore("key_ids")`. With the normal configuration the
+file is:
+
+```text
+<SystemConfig.data_path>/databases/key_ids/key_ids.sqlite
+```
+
+The database contains one table and two indexes:
+
+```sql
+CREATE TABLE store (ns TEXT, key TEXT, value TEXT);
+CREATE UNIQUE INDEX key_index ON store(ns, key);
+CREATE INDEX ns_index ON store(ns);
+```
+
+The SQLite `rowid` is the generated Spark key. `ns` is normally
+`<VENUE>.<SECURITY_TYPE>` (for example `GLBX.FUTURE`), and `key` is the security
+descriptor chosen by the caller. `value` is normally empty. Therefore ID
+stability depends on all three of these remaining stable:
+
+- the configured `data_path` and preservation of this database;
+- the venue/type namespace;
+- the descriptor supplied by the feed adapter.
+
+The two allocator implementations share the file and convention:
+
+- `SecurityIDRecorder` (legacy): derives the namespace from legacy API enums and
+  uses `securities::descriptor()`. For CME this is the Globex
+  `security_desc`, populated from the definition's symbol/tag 55.
+- `IDGenerator` (newer): derives the namespace from new domain enums and uses
+  the caller's `name`. Most adapters pass `sec.desc()` or an exchange instrument
+  identifier; Databento deliberately passes the decimal instrument ID, and the
+  Python bridge uses the exchange security ID.
+
+### Logical-row examples
+
+The following names are illustrative. Production uses the exact string emitted
+by the selected feed/adapter, including its case, spacing, and weekly-series
+notation.
+
+#### Legacy `SecurityIDRecorder`
+
+For CME, `set_security_common()` copies the MDP3 definition's symbol/tag 55 into
+Globex `security_desc`. After converting the fixed security to
+`api::Security`, `securities::descriptor()` returns that same
+`glbx.security_desc()` string.
+
+| Instrument | Legacy enums | Example descriptor from `security_desc` | Row searched/inserted in `store` |
+|---|---|---|---|
+| Future | `VENUE_GLBX`, `SECURITYTYPE_FUTURE` | `ESZ6` | `ns='GLBX.FUTURE', key='ESZ6'` |
+| Standard option | `VENUE_GLBX`, `SECURITYTYPE_OPTION` | `ESZ6 C6500` | `ns='GLBX.OPTION', key='ESZ6 C6500'` |
+| Weekly option | `VENUE_GLBX`, `SECURITYTYPE_OPTION` | `ESZ6-W1 C6500` | `ns='GLBX.OPTION', key='ESZ6-W1 C6500'` |
+| Spot from a legacy-compatible venue path | `VENUE_COINBASE`, `SECURITYTYPE_SPOT` | `BTC-USD` | `ns='COINBASE.SPOT', key='BTC-USD'` |
+
+A weekly option does not get a special namespace. Standard and weekly options
+are both `SECURITYTYPE_OPTION`, so both live in `GLBX.OPTION`; the exact
+`security_desc` distinguishes the weekly series. For example, if the database
+assigned rowids `42001` through `42004` to the rows above, those integers—not
+the descriptor strings—would be the Spark security keys.
+
+Conceptually, legacy allocation is:
+
+```text
+future:        lookup_or_insert("GLBX.FUTURE",  "ESZ6")
+option:        lookup_or_insert("GLBX.OPTION",  "ESZ6 C6500")
+weekly option: lookup_or_insert("GLBX.OPTION",  "ESZ6-W1 C6500")
+spot:          lookup_or_insert("COINBASE.SPOT", "BTC-USD")
+```
+
+#### Newer `IDGenerator`
+
+The namespace result is similar, but the third argument is chosen by the
+adapter. Examples using a description-oriented adapter are:
+
+```cpp
+get_or_add(VENUE_GLBX, SECURITY_TYPE_FUTURE, "ESZ6");
+// store: ns="GLBX.FUTURE", key="ESZ6"
+
+get_or_add(VENUE_GLBX, SECURITY_TYPE_OPTION, "ESZ6 C6500");
+// store: ns="GLBX.OPTION", key="ESZ6 C6500"
+
+get_or_add(VENUE_GLBX, SECURITY_TYPE_OPTION, "ESZ6-W1 C6500");
+// store: ns="GLBX.OPTION", key="ESZ6-W1 C6500"
+
+get_or_add(VENUE_COINBASE, SECURITY_TYPE_SPOT, "BTC-USD");
+// store: ns="COINBASE.SPOT", key="BTC-USD"
+```
+
+Databento intentionally produces a different logical row even when the human
+description is `ESZ6`. If its instrument ID were `12345678`, it would call the
+equivalent of:
+
+```cpp
+get_or_add(VENUE_GLBX, SECURITY_TYPE_FUTURE, "12345678");
+// store: ns="GLBX.FUTURE", key="12345678"
+```
+
+Likewise, the Python bridge uses `exchange_security_id`. A spot definition with
+`exchange_security_id="BTC-USD"` produces the `COINBASE.SPOT / BTC-USD` row,
+while a provider that sends `exchange_security_id="BTCUSD"` produces a
+different row and therefore a different Spark key.
+
+These examples show why the tuple is only logical when the adapter's naming
+contract is also known. `GLBX.FUTURE / ESZ6` and `GLBX.FUTURE / 12345678` may
+describe the same contract to a human but are distinct rows to `key_ids.sqlite`.
+
+Both enum-prefix removals currently produce the same namespace spelling (for
+example, `GLBX.OPTION`), so both mechanisms allocate from one global SQLite
+rowid space. Live rows cannot share a rowid. The table does not declare
+`AUTOINCREMENT`, however, so deleting rows—especially the highest row—can allow
+SQLite to reuse a number later. Security-key rows should therefore be treated
+as append-only operational data.
+
+`SqliteStore` uses WAL mode and `PRAGMA synchronous = 0`. This favors startup
+and feed latency over maximum durability against a host/power failure. The
+unique `(ns, key)` index prevents two different rows for the same logical
+security.
+
+### Other places the key is stored
+
+| Location | Purpose | Authoritative for allocation? |
+|---|---|---|
+| Hot and cold shared-memory segments | Live publication and fast consumer lookup | No; rebuilt at process startup |
+| `CMESecurityIndex` / `GeneralSecurityIndex` and adapter maps | In-process routing from an incoming ID to a producer handle | No; in-memory only |
+| `<data_path>/databases/md/securities.sqlite` | Serialized legacy `api::Security` definitions keyed by Spark key; used by security cache and MDP3 Sunday preload | No; it stores metadata after a key exists |
+| Relay/market-data recordings | Preserve the key embedded in recorded securities, books, and trades for deterministic replay | No; replay normally reuses the recorded value |
+| Orders, fills, positions, APIs | Reference a security by the published Spark key | No |
+
+The `SecurityIDRecorder::work_db()` comment says a published security is also
+recorded in the security database, but that function does **not** write
+`securities.sqlite` in the current code. Full security definitions are persisted
+separately by `SecurityCache::flush_to_disk()` through
+`db::insert_or_replace()`.
+
+## CME MDP3 / OnixS pipeline in detail
+
+### 1. Construction and thread setup
+
+`MDP3Main::PImpl` owns one `CMESecurityIndex`, one `SecurityIDRecorder`, and one
+`MDProducer`. It constructs the recorder with:
+
+- a lookup callback that maps `ExchangeKey` through the CME index to the
+  handle's current Spark key; and
+- `Dispatcher::current()`, which drives a 200 ms recorder timer.
+
+In the current `MarketDataGateway` route, `OnixsGlbxSubscription` creates a
+dedicated `dispatcher_thread`, constructs and starts `MDP3Main` on that thread,
+then calls that thread's dispatcher `run()`. The older `md run onixs` command
+uses its command/dispatcher thread similarly.
+
+The OnixS feed engine has its own configured thread pool. Instrument and market
+data callbacks therefore originate on OnixS feed-engine threads, while recorder
+database work and final key assignment execute on the MDP3 dispatcher thread.
+
+| MDP3 stage | Executing thread | DB call? |
+|---|---|---|
+| Decode definition and set CME `numeric_id` | OnixS feed-engine callback thread | No |
+| Allocate hot/cold entry and queue handle | Same OnixS callback thread | No |
+| Add CME-ID index entry | Same OnixS callback thread | No |
+| Resolve spread legs | MDP3 dispatcher thread, on 200 ms timer | No |
+| Select/insert Spark key | MDP3 dispatcher thread, on 200 ms timer | Yes |
+| `handle.set_key()` and public visibility | MDP3 dispatcher thread, in DB callback | No additional call |
+
+### 2. Definition callback: exchange ID is set, Spark key is not
+
+For futures, options, and spreads, `MDP3Listener::set_security_common()` does:
+
+```cpp
+fsec.numeric_id = def.securityId();
+```
+
+It also copies symbol/descriptor/venue and pricing fields. A newly constructed
+`FixedSecurity` already has `key == invalid_security_key` (`0`), and this helper
+does not change it.
+
+For a spread, every leg starts with:
+
+```cpp
+leg.exchange_key = ExchangeKey(definition_leg.legSecurityId());
+leg.key = invalid_security_key;
+```
+
+Thus both the parent and legs initially carry exchange-routing identity, but no
+Spark identity.
+
+### 3. Shared-memory allocation and exchange indexing
+
+`MDP3Listener::add_security()` performs these operations in order:
+
+1. `_producer.add_security(security)` allocates a hot entry and a variable-sized
+   cold entry and copies the security into the cold segment.
+2. Because the key is `0`, `MDProducer` queues the handle through
+   `SecurityIDRecorder::ensure_key()`.
+3. `_index.add_security(security.numeric_id, handle)` immediately creates the
+   CME-ID-to-handle mapping.
+4. The initial exchange status is written through the handle.
+
+This ordering means incoming books can already be routed by CME ID while the
+Spark key is pending. Shared-memory consumers cannot discover the security yet.
+Also, `MDProducerHandle::add_trade()` only appends to the public trade queue
+when `key() != 0`, so a trade received in this short window updates the cold
+last-trade state but is not added to the keyed trade log.
+
+### 4. Recorder tick: spreads, handles, then database
+
+Every 200 ms the recorder calls, in this exact order:
+
+1. `work_spreads()` tries to fill previously unresolved spread leg keys by
+   asking `CMESecurityIndex` for each leg exchange ID.
+2. `work_handles()` drains new handles. Outrights are converted to an API
+   security and queued for DB lookup immediately. A spread without all leg keys
+   is retained in `pending_handle` and its leg pointers are registered in
+   `unresolved_legs`.
+3. `work_db()` resolves queued `(venue, type, descriptor)` requests.
+
+Because spread work precedes new-handle work, a newly seen unresolved spread
+normally waits until at least the next timer tick to resolve legs. It waits
+longer if any outright leg has not yet received its Spark key. A spread's own
+key is not requested until every leg key is non-zero.
+
+### 5. Lookup or generation
+
+`work_db()` first queries `(ns, key)`:
+
+- Existing row: use its `rowid` as the key and invoke the callback.
+- Missing row: batch it into `insert_many_resolve_ids()`. SQLite assigns a new
+  rowid inside a transaction, the row object receives that ID, and the callback
+  runs after the transaction completes.
+
+New inserts are throttled to roughly 200 per timer pass (the current `> 200`
+check can admit 201) to avoid delaying heartbeats during startup. The queues are
+TBB concurrent queues, but all SQLite access is serialized onto the recorder's
+dispatcher thread. `check_access()` asserts this single-thread rule after the
+first work pass records the dispatcher thread ID.
+
+### 6. Final assignment and visibility
+
+The queued callback captures a copy of `MDProducerHandle` and calls
+`handle.set_key(id)` on the dispatcher thread. `set_key()` writes hot, then cold,
+then increments `security_count`. From this point:
+
+- shared-memory scans report the security;
+- `CMESecurityIndex::get_key(CME_ID)` returns the Spark key;
+- trades and RFQs can be emitted with a non-zero key;
+- resolved spreads can copy this key into their leg structures.
+
+### 7. Sunday preload is a fast path
+
+For configured symbols on Sunday, `MDP3Main::prepare_listener()` loads stored
+definitions from `securities.sqlite`. It converts them with
+`set_security_key=true`, so both the security key and spread leg keys come from
+the serialized API security. `MDProducer::add_security()` calls `set_key()`
+immediately, and no recorder lookup is required for that preloaded handle. The
+CME exchange ID is still restored into `numeric_id`, allowing the normal CME
+index to be built.
+
+## Generalized/newer pipeline in detail
+
+### 1. Topology and ownership
+
+`Run::run()` starts a detached thread named `MarketDataGateway`. On that thread,
+`run_md_gwy()` obtains the process-wide `IDGenerator`, constructs
+`MarketDataGateway`, and starts the configured providers. For each `(venue,
+source)` returned by a provider, the gateway creates an `MdSink` containing:
+
+- a venue-local `GeneralSecurityIndex`;
+- a default `MDProducer` (not wired to a `SecurityIDRecorder`); and
+- a `GeneralMarketDataListener` connecting the source to that producer/index.
+
+The source decides its callback thread. Some sources call the listener while
+starting; others own network or replay threads. The generalized listener calls
+the producer inline on that source thread. The process-wide `IDGenerator`
+serializes its own calls with a mutex, but the listener's transient
+`cc_sec_id_map` is an ordinary `unordered_map`, so each source/listener pair is
+expected to serialize security/event callbacks.
+
+| Generalized stage | Executing thread | DB call? |
+|---|---|---|
+| Build/parse domain definition | Source/adaptor thread | No |
+| `IDGenerator::get_or_add()` | Same source/adaptor thread | Yes, synchronously |
+| `GeneralMarketDataListener::on_securities()` | Same source callback thread | No in current use-given mode |
+| Copy ID to `FixedSecurity::key` and `numeric_id` | Same source callback thread | No |
+| `MDProducer::add_security()` / `set_key()` | Same source callback thread | No additional call |
+| Add `GeneralSecurityIndex` entry | Same source callback thread | No |
+
+There are two important compatibility exceptions inside the provider framework:
+
+- `OnixsGlbxSubscription::start()` ignores the supplied generalized listener
+  and starts `MDP3Main`; CME/OnixS therefore still follows the asynchronous
+  legacy flow documented above.
+- `EmumbaDeribitSubscription::start()` also ignores that listener and uses
+  `EmMDListener`, which allocates via `IDGenerator` and writes through its own
+  producer/index. Its assignment is still synchronous and pre-populated, so it
+  resembles the newer ID flow even though it does not pass through
+  `GeneralMarketDataListener`.
+
+### 2. How a new ID is constructed
+
+For a normal live generalized adapter, ID creation happens **in the adapter,
+before** `GeneralMarketDataListener::on_securities()`:
+
+```text
+logical identity = (domain venue, domain security type, adapter-chosen name)
+Spark ID         = SQLite rowid for that identity in key_ids.sqlite
+```
+
+`IDGenerator::get_or_add(venue, type, name)` formats a namespace by stripping
+the enum prefixes:
+
+```text
+VENUE_TAIFEX + SECURITY_TYPE_FUTURE -> TAIFEX.FUTURE
+```
+
+It then calls `retrieve_one(ns, name)`. If the row exists, it returns that
+row's `rowid`. If absent, it inserts `(ns, name, "")`, and SQLite assigns the
+next rowid. That integer is wrapped in `domain::SecurityID` and placed in
+`SecurityCommon::id`.
+
+The third identity component is adapter-specific, and this matters when trying
+to reproduce a mapping:
+
+| Source/adaptor family | Typical `name` sent to `IDGenerator` |
+|---|---|
+| Binance, Coinbase, Deribit, OKX and similar native/CCAPI paths | Usually `sec.desc()` / exchange instrument name |
+| Taifex | product/instrument ID string |
+| Databento | `std::to_string(msg.hd.instrument_id)`, not the human-readable description |
+| Python bridge | `exchange_security_id` (and it asserts Python supplied ID is zero for definitions) |
+| Emumba Deribit | extracted Emumba security descriptor |
+| Replay | no new allocation for a recorded definition; it reuses the recorded `SecurityCommon::id` |
+
+So “security name” alone is not a universal logical key. Reproduction requires
+the exact venue enum, exact security-type enum, and the exact adapter-specific
+name used at insertion time.
+
+### 3. What `GeneralMarketDataListener` does with that ID
+
+`on_securities()` first calls `_find_sec(sec, true)`. Its current, compile-time
+behavior is controlled by:
+
+```cpp
+const bool use_given_sec_key = true;
+```
+
+Consequently, for a newly seen incoming `domain::SecurityID` it does **not**
+call the DB. It copies `security_common.id.value()` into its transient
+`cc_sec_id_map`. `_add_future()`, `_add_option()`, `_add_spread()`, or
+`_add_spot()` then calls `_copy_security_common()`, which sets:
+
+```cpp
+to.key = incoming_id;
+to.numeric_id = incoming_id;
+```
+
+This collapses the generalized source/correlation ID and Spark shared-memory
+key into the same number. The source's text `exchange_sec_id` remains on the
+domain security but is not copied into `FixedSecurity::numeric_id` by this
+path.
+
+`_commit_security()` then:
+
+1. calls `MDProducer::add_security()` with an already non-zero key;
+2. causes `MDProducerHandle::set_key()` to run immediately during that call;
+3. inserts the handle in `GeneralSecurityIndex` under `numeric_id` (the same
+   number); and
+4. returns with the security already visible in shared memory.
+
+Because the sink's producer has no recorder, supplying `id == 0` would allocate
+the shared-memory entry but never assign or publish its key. Generalized live
+sources must therefore provide a valid non-zero ID before `on_securities()`.
+
+The listener contains an alternative branch for `use_given_sec_key == false`.
+That branch would call `IDGenerator::get_or_add(me->venue, sec.type(),
+sec.desc())` itself. It is currently disabled, and `_generate_security_key()` is
+also effectively unused. Turning the flag off is not a mechanical change: an
+adapter such as Databento allocates using numeric instrument ID while the
+listener branch would use `sec.desc()`, potentially creating a second key for
+the same instrument.
+
+There is also a spread failure edge case. `_find_sec(sec, true)` records the
+parent ID in `cc_sec_id_map` before `_add_spread()` resolves its legs. If any leg
+ID is absent, `_add_spread()` logs and returns without committing the spread. A
+later repeat of the parent definition is then classified as a duplicate and
+ignored, so definition ordering is a hard requirement in the current code.
+
+### 4. How later books, trades, and statistics find the security
+
+Every later domain event carries a `domain::SecurityID`:
+
+- `Book::security_id()`;
+- `TradeRecord::sec_id`; or
+- `SecurityMarketDataStatistics::security_id`.
+
+The listener first uses `cc_sec_id_map` to translate that event ID to the value
+stored in `GeneralSecurityIndex`, then obtains the `MDProducerHandle`. With
+`use_given_sec_key == true`, this mapping is numerically identity-to-identity,
+but it still serves as the admission check that the definition was seen.
+
+Most high-throughput adapters avoid SQLite on market-data events:
+
+- Databento allocates on the definition and caches
+  `instrument_id -> domain::SecurityID` in `sec_id_map` for books/trades.
+- Taifex keeps the resolved ID in its security-details mapper.
+- Other native subscriptions maintain comparable descriptor/ID maps.
+
+The Python bridge is a notable exception: `to_bts_security_()`,
+`to_bts_trade_()`, and `to_book_()` all call `get_sec_id_()`, which calls
+`IDGenerator::get_id(..., add_if_new=true)`. As written, that performs at least
+one SQLite `SELECT` for each converted Python definition, trade, or book. It
+returns the existing ID after the first insert, but it is still a DB call and
+takes the global `IDGenerator` mutex on every event.
+
+### 5. Persistence timing and latency
+
+The newer allocator is synchronous:
+
+- Existing security: mutex acquisition plus one SQLite `SELECT` on the caller's
+  thread.
+- New security: mutex acquisition, one `SELECT`, then one SQLite `INSERT`
+  (SQLite autocommit), also on the caller's thread.
+- Listener publication: no further DB call under the current
+  `use_given_sec_key` setting.
+
+The ID therefore exists in `key_ids.sqlite` before the adapter sends the
+definition to the listener. There is no intentional 200 ms publication delay,
+but the source callback/startup path directly pays DB and mutex latency. Bulk
+definition discovery performs one lookup and possibly one insert per security;
+`IDGenerator` does not batch those operations.
+
+WAL mode helps concurrency, while `synchronous=0` reduces fsync cost. It does
+not eliminate SQL parsing/stepping, mutex contention, page-cache misses, or
+occasional file-system work. The impact is usually a startup/definition cost
+when adapters cache the result, but it becomes hot-path latency for code such as
+the current Python bridge that resolves every event through the DB.
+
+`GeneralMarketDataListener` itself does not persist the full contract definition
+to `securities.sqlite`; that remains the separate security-cache/metadata
+persistence path described earlier.
+
+## Comparison: MDP3 recorder vs generalized allocator
+
+| Property | MDP3 / `SecurityIDRecorder` | Generalized / `IDGenerator` |
+|---|---|---|
+| Logical input | venue + type + legacy `security_desc` | venue + type + adapter-chosen name |
+| Numeric output | SQLite rowid, checked/read as 32-bit `security_key` | SQLite rowid returned as 64-bit `domain::SecurityID`, then narrowed into 32-bit shared-memory key |
+| Allocation point | After definition is copied to shared memory | Normally inside adapter before listener sees definition |
+| DB execution | Asynchronous on dispatcher timer | Synchronous on caller/source thread |
+| Existing ID cost | One deferred `SELECT` | One immediate `SELECT` per call |
+| New ID cost | Deferred, batched transaction (about 200/pass) | Immediate `SELECT` + individual autocommit `INSERT` |
+| Time until public | Usually 0–200+ ms; spreads may take extra ticks | Immediate after synchronous lookup/insert completes |
+| Feed callback blocking | Queue push only for ID work | Yes, if the adapter invokes `IDGenerator` there |
+| Spread legs | Parent waits asynchronously until all leg keys resolve by exchange ID | Definition processing requires every leg's incoming ID already exist in `cc_sec_id_map`; otherwise the spread is aborted |
+| Runtime ID relationship | Exchange ID and Spark key remain distinct | Incoming/canonical ID, `numeric_id`, index ID, and Spark key are currently the same number |
+| Persistence database | `key_ids.sqlite` | The same `key_ids.sqlite` |
+| Batching | Yes for new rows | No |
+| Failure behavior | Security has an internal handle with key 0 while normal queued work is pending; DB work does not block the feed callback | DB errors/zero results occur in the synchronous source path; a zero ID can leave an unpublishable entry, with no pending-key state machine |
+
+Neither algorithm generates a UUID or a content hash. Both ultimately use an
+opaque, database-assigned SQLite rowid. It is normally increasing and looks like
+a sequence, but this schema does not request SQLite `AUTOINCREMENT`. The tuple
+used to *look up* the row is logical; the resulting number is not derivable from
+that tuple.
+
+## Can another system reconstruct the same keys?
+
+Not from `(venue, type, name)` alone. Another system can reconstruct the
+**logical lookup tuple**, but it cannot calculate the numeric Spark key because
+the key depends on the historical insertion order of every row in
+`key_ids.sqlite`.
+
+For example, two empty systems can insert the exact same `GLBX.FUTURE / ESZ6`
+row and receive different IDs if other securities were inserted before it on
+one system. They are sequential opaque IDs, not deterministic hashes and not
+UUIDs.
+
+Ways to preserve cross-system identity are:
+
+1. Copy/replicate `key_ids.sqlite` (including rowids) and keep descriptor rules
+   identical. This preserves existing numeric keys but requires coordinated
+   allocation for new ones.
+2. Export an explicit mapping of `(namespace, adapter key) -> Spark key`, then
+   import rows with their original rowids before either system allocates new
+   securities.
+3. Treat a stable external identity (venue + type + exchange instrument ID, or
+   another canonical instrument identifier) as the cross-system key and carry a
+   translation table to each system's local Spark key.
+4. Introduce a deterministic ID scheme only as a versioned migration. A hash can
+   be computed independently, but collision handling, descriptor
+   canonicalization, aliases/renames, the existing 32-bit ABI, and compatibility
+   with orders/recordings/databases all need explicit design.
+
+Copying only `securities.sqlite` is insufficient as an allocator strategy. It
+contains security blobs keyed by already-assigned IDs, but `key_ids.sqlite` is
+the mapping used to find or allocate those IDs. Conversely, copying only
+`key_ids.sqlite` preserves the numbers but not all contract metadata.
+
+## Other assignment paths in `sparkd`
+
+The two main pipelines reduce to four ways a producer handle can acquire a key:
+
+1. **Already keyed input.** `MDProducer::add_security()` sees a non-zero
+   `FixedSecurity::key` and calls `set_key()` immediately. Generalized feeds,
+   Sunday preload, relay playback, and other replay paths use this mechanism.
+2. **Recorder-backed live input.** The input key is zero and the producer owns a
+   `SecurityIDRecorder`; `ensure_key()` queues asynchronous assignment. CME
+   MDP3 and legacy OnixS ICE use this mechanism. ICE uses `marketId` as
+   `numeric_id` and otherwise follows the same recorder/index design.
+3. **Service assignment.** `SyntheticSecurityService` calls
+   `SecurityIDRecorder::assign_key()` directly on a background dispatcher. The
+   callback receives a copied `api::Security` with its top-level `id` set, then
+   publishes it to synthetic subscribers. It uses the same `key_ids.sqlite`
+   rowid allocator.
+4. **Unkeyed input with no recorder.** The entry is allocated with key zero and
+   never becomes public. This is not a valid production assignment path, but it
+   is the failure mode if a generalized source omits its ID.
+
+Relay and replay deserve care when reasoning about persistence:
+
+- The generalized `MDReplayer` forwards the recorded domain security ID and
+  emits later books/statistics with the recorded `sec_key`, so the listener's
+  current use-given mode preserves the recording's numeric identity.
+- The legacy relay producer converts a recorded `api::Security` with
+  `set_security_key=true`, so its shared-memory publication also preserves the
+  embedded key.
+- The legacy relay recorder additionally calls `bulk_insert(..., "REPLAY: ")`
+  for logical mappings. Those rows use a `REPLAY: ` namespace prefix; this is a
+  separate mapping population step, not a deterministic derivation of the key.
+
+## Operational implications
+
+- Back up `key_ids.sqlite` and `securities.sqlite` together if numeric ID and
+  definition continuity matter.
+- Do not delete/rebuild `key_ids.sqlite` on one host and assume IDs will match
+  another host, even when all instruments are identical.
+- Before moving a feed between adapters, compare the exact `name` each adapter
+  supplies to `IDGenerator`. Matching venue/type is insufficient.
+- Cache generated IDs in the source after definition processing. Avoid calling
+  `IDGenerator` from book/trade hot paths; the Python bridge currently violates
+  this guideline.
+- Keep generated rowids below the 32-bit shared-memory ceiling until the
+  `security_key` ABI is widened or explicit bounds checking is added to the
+  generalized path.
+- Ensure spread legs are announced before generalized spread parents.
+- Treat `synchronous=0` as a durability decision. A copied DB should be taken
+  with SQLite-aware backup/checkpoint handling rather than by casually copying
+  active WAL files.
+
+Useful inspection queries (run against the configured DB path) are:
+
+```sql
+SELECT rowid AS spark_key, ns, key
+FROM store
+ORDER BY rowid;
+
+SELECT rowid AS spark_key, ns, key
+FROM store
+WHERE ns = 'GLBX.FUTURE' AND key = '<exact-adapter-key>';
+```

-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
-
-Currently, two official plugins are available:
-
- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react/README.md) uses [Babel](https://babeljs.io/) for Fast Refresh
- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
