/**
 * # adapters/broker — the venue-agnostic broker/feed adapter SEAM (kestrel-7o2.4, increment 1)
 *
 * The charter claim this module proves: **`sim | paper | live` is ONE Session path where only the
 * gate behind the seam differs** (CONTEXT: Mode — "one engine path; only the gate differs"; sim.ts
 * §"One code path, one gate"). This file names the two seams that make that true and the mode-keyed
 * factory that selects a gate — WITHOUT any IBKR code, any network, any npm dependency, or any
 * real-money path (that is a later increment).
 *
 * ## The execution seam is ALREADY the Gate (engine/plans.ts)
 * The engine hands the gate an {@link OrderIntent} that is **fully resolved before it arrives**: a
 * numeric `px` (a silent mid is forbidden, RUNTIME §4), never-naked enforced, the price-resolution
 * receipt (`sourceAnnotation`) attached, the directional-guard evidence (`moneyness`/`covered`)
 * threaded. So a broker adapter is a **TRANSMITTER, never a re-pricer** — it routes the intent to a
 * venue and reports back what the venue did. A {@link BrokerAdapter} IS a {@link Gate}.
 *
 * ## How the reference gate (SimGate, session/sim.ts) surfaces ORDER events — the pattern to MIRROR
 * `SimGate.submit` is SYNCHRONOUS: it rests the intent in the {@link SimFillEngine} (the judge) and
 * returns a `string` ref. The fill engine APPENDS its typed ORDER events (`place | fill | reject |
 * cancel`) to a cumulative `events` buffer; an injected `drain()` closure slices the fresh ones onto
 * the emitted bus (stamping `seq`). The engine learns of fills ONLY by OBSERVING `ORDER fill` bus
 * events — `SessionCore.step` feeds each drained fill back via `engine.onEvent(fillEvent)` (the
 * fills-before-sweep ordering, RUNTIME §7). The engine never simulates a fill itself.
 *
 * A {@link BrokerAdapter} mirrors this EXACTLY (it does not invent a divergent event path): it holds
 * an `events` buffer of seq-less {@link NewBusEvent}s, its `submit`/`cancel` append `place | fill |
 * reject | cancel` records to it, and the SAME injected `drain()` surfaces them + feeds fills back to
 * the engine. The {@link OrderAction} set is CLOSED (`place | cancel | fill | reject`, bus/types.ts,
 * guarded by `isValidStreamType`) — an adapter stays within it.
 *
 * ## The FEED seam is the bus itself
 * There is NO abstract feed interface in the runtime today: `SessionCore.step(ev: BusEvent)` consumes
 * the {@link BusEvent} union directly (a `META` header + `TICK/BOOK` carrying the real
 * `OptionQuote[]` legs + `underlier_px` + `TICK/SPOT` carrying `px`/`bid`/`ask`). A {@link FeedSource}
 * is therefore exactly a **producer of that SAME union** — the mock replays a deterministic in-memory
 * sequence; a live feed would translate a venue's market-data stream into the identical shapes. No new
 * event type is introduced, so `SessionCore.step` folds a FeedSource's output with zero changes.
 *
 * ## Mode is first-class, and LIVE fails closed
 * `Mode` is `sim | paper | live` (bus/types.ts); the record layer already branches on it (`fidelityOf`,
 * `instanceIdentityOf`). The protocol authorization scopes DELIBERATELY EXCLUDE `broker`/`live` from
 * {@link WALLET_SIGNABLE_SCOPES} (protocol/index.ts) — **live authority requires a human signature, never
 * a wallet/config alone**. {@link makeGate} encodes exactly that boundary: `sim` returns a SimGate
 * (byte-identical to today), `paper` returns a {@link BrokerAdapter}-backed gate, and `live` FAILS CLOSED
 * with a typed {@link LiveGateRefused} UNLESS an explicit, human-authorized {@link LiveArm} is present.
 * **This increment provides NEITHER a live arm NOR live routing** — so the only correct outcome for `live`
 * here is the typed refusal.
 *
 * @remarks Increment 1 is the SEAM + the fail-closed factory. The green implementation (the reference
 * paper adapter's fill model, the SimGate construction, the live arm's signature verification) lands
 * behind these shapes; the stubs below throw {@link NotImplemented} until then.

 *  - `"not-a-number"` — a non-finite `qty`/`px`. `NaN > ceiling` is `false` for EVERY ceiling, so a NaN
 *    silently satisfies all three limits and transmits. Fail-closed demands the inverse: an unorderable
 *    number is REFUSED, never waved through.
 *  - `"multiplier"` — a non-finite or non-positive contract multiplier. `notional = px·qty·multiplier`,
 *    so a `0` multiplier computes EVERY notional as `0` and the `maxNotionalUsd` ceiling becomes inert
 *    (a `NaN`/negative one corrupts it just as silently). The ceiling is only as real as its inputs.
 *  - `"malformed-intent"` (kestrel-ct9m) — a FINITE but unorderable `qty`/`px`: a qty that is not a
 *    POSITIVE INTEGER (negative, zero, fractional) or a px that is not POSITIVE. Same fail-open shape as
 *    the NaN one, one step removed: `-1_000_000 > maxOrderQty` is `false`, `px · -1_000_000 · mult >
 *    maxNotionalUsd` is `false` (the notional goes NEGATIVE), and `projected = current + (buy ? qty :
 *    -qty)` SIGN-INVERTS, so a million-lot sell clears every ceiling and transmits. A `0`/negative px
 *    collapses or inverts the notional the same way. The L0 seam may not delegate its own validity to a
