The hosted synthetic market already reaches the smart-money categories, but it often reaches them too cleanly. This redesign makes the demo feel more like a market session: one shared regime drives options, equities, quotes, event context, and coverage pressure, while operators keep a compact internal handle on the simulator through a bottom-right gear.

<strong>What changes for a viewer</strong>

The tape looks less templated, more coherent, and more educational because the surrounding market conditions finally support the category hits.

<strong>What changes for an operator</strong>

A small bottom-right gear opens a non-modal synthetic-control drawer for the hosted backend.

<strong>What does not change</strong>

<h2>Simplified Overview</h2>
|
||||
<p>
|
||||
The current synthetic system is strong at coverage and weaker at realism. It can produce the categories, but the tape often reveals the machinery: option bursts appear on a rhythm, quotes are too consistently clean, equities and options are only loosely related, and the market context around a labeled event is not convincing enough.
|
||||
</p>
|
||||
<p>
|
||||
The redesign introduces a shared market regime engine. Instead of “emit a category-shaped burst now,” the system will model a believable session state first, then let both options and equities express that state. That keeps the smart-money demo behavior while making the experience feel more grounded.

<h2>Full Architecture</h2>
|

|

<h3 class="accent-sage">1. Replace the burst pulse with a shared regime engine</h3>
|
||||
<p>Expand <code>packages/types/src/synthetic-market.ts</code> into the shared deterministic engine used by both ingest services.</p>
|

<p>Shared functions:</p>
|

<ul>
|

<li><code>getSyntheticScenarioWeights(symbol, ts, control, sessionState)</code></li>
|
||||
<li><code>getSyntheticCoverageBoost(profileId, coverageState, control)</code></li>
|
||||
</ul>
|
||||
<p><code>sessionState</code> includes:</p>
|
||||
<ul>
|
||||
<li><code>session_phase</code>: <code>open | midday | power_hour | after_event</code></li>
|
||||
<li><code>regime</code>: <code>trend_up | trend_down | mean_revert | retail_chase | event_ramp | dealer_gamma | arb_calm</code></li>

<li><code>event_symbols</code></li>
|
||||
<li><code>seed_bucket</code></li>
|
||||
</ul>
|
||||
|
||||
<h3 class="accent-teal">2. Add hosted synthetic control state</h3>
|
||||
<p>Add internal control schemas in <code>packages/types</code>:</p>
|
||||
<ul>
|
||||
<li><code>SyntheticControlPresetId</code></li>
|
||||
<li><code>SyntheticControlState</code></li>
|

|

<p>Defaults: <code>preset_id: balanced_demo</code>, <code>coverage_assist: true</code>, <code>coverage_window_minutes: 20</code>, all profile weights <code>1.0</code>.</p>
|
||||
|
||||
<h3 class="accent-gold">3. Persist and distribute control state through NATS</h3>
|
||||
<ul>
|
||||
<li>Use JetStream KV bucket <code>synthetic_control</code></li>
|
||||
<li>Use key <code>global</code></li>
|
||||
<li><code>services/api</code> reads and writes the KV entry</li>
|

<li><code>services/ingest-options</code> loads on boot and watches for updates</li>
|
||||
<li><code>services/ingest-equities</code> does the same</li>
|
||||
</ul>
|
||||
|
||||
<h3 class="accent-rose">4. Rebuild options scenarios as hidden subtype families</h3>
|
||||
<ul>
|
||||
<li><strong><code>institutional_directional</code></strong>: <code>call_sweep</code>, <code>put_sweep</code>, <code>ask_lift_accumulation</code>, <code>far_dated_conviction</code></li>
|
||||
<li><strong><code>retail_whale</code></strong>: <code>0dte_call_chase</code>, <code>short_dated_put_panic</code>, <code>attention_contract_spike</code></li>
|
||||
<li><strong><code>event_driven</code></strong>: <code>earnings_vol_probe</code>, <code>pre_event_directional_ramp</code>, <code>post_gap_followthrough</code></li>
|
||||
<li><strong><code>vol_seller</code></strong>: <code>covered_call_overwrite</code>, <code>cash_secured_put_write</code>, <code>short_straddle_harvest</code></li>
|

<li><strong><code>arbitrage</code></strong>: <code>parity_vertical</code>, <code>conversion_reversal</code>, <code>box_spread</code></li>
|

<li><strong><code>hedge_reactive</code></strong>: <code>gamma_pinch_call_hedge</code>, <code>reactive_put_wall</code>, <code>dealer_unwind</code></li>
|
||||
<li><strong><code>neutral_noise</code></strong>: <code>single_print_mid</code>, <code>two_sided_scalp</code>, <code>stale_quote_noise</code></li>
|
||||
</ul>
|
||||
<p>Hidden subtype labels remain internal and test-only. They should never appear on emitted option prints or public smart-money events.</p>
|
||||
|
||||
<h3>5. Make equities and options react to the same latent state</h3>
|
||||
<div class="split">
|
||||
<div class="panel">
|
||||
<h3>Equities changes</h3>
|
||||
<ul>
|
||||
<li>Remove the fixed dark-sequence loop</li>
|
||||
<li>Make lit versus dark balance regime-dependent</li>
|
||||
<li>Make spread, quote cleanliness, off-exchange frequency, and clustering regime-dependent</li>
|
||||
<li>Use shared focus symbols</li>
|
||||
<li>Make <code>event_ramp</code> and <code>retail_chase</code> show modest trend and wider quotes</li>
|
||||
<li>Make <code>dealer_gamma</code> show choppier reversals and denser quote changes</li>
|
||||
<li>Make <code>arb_calm</code> quieter and more neutral</li>
|
||||
</ul>
|
||||
</div>
|
||||
<div class="panel">
|
||||
<h3>Options changes</h3>
|
||||
<ul>
|
||||
<li>Replace hardcoded coverage forcing with weighted family selection plus coverage debt</li>
|
||||
<li>Make venue count, placement, stale or missing quote probability, and structure prevalence regime-sensitive</li>
|
||||
<li>Derive <code>execution_iv_shock</code>, <code>underlying_move_bps</code>, and <code>nbbo_spread_z</code> from shared state</li>
|
||||
<li>Generate event-driven timestamps and symbols from shared regime state</li>
|
||||
</ul>
|
||||
</div>
|
||||
</div>
|
||||
|
||||
<h3>6. Add soft coverage accounting</h3>
|
||||
<ul>
|
||||
<li>Track rolling coverage debt per public profile inside each ingest service</li>
|
||||
<li>Maintain a rolling counter across the selected <code>coverage_window_minutes</code></li>
|
||||
<li>Only public profiles count toward coverage</li>
|
||||
<li>Missing profiles get a bounded weight boost</li>
|
||||
<li>Noise and low-key scenarios continue to appear between labeled bursts</li>
|
||||
</ul>
|
||||
|
||||
<h3>7. Add internal hosted control endpoints</h3>
|
||||
<p>Add routes in <code>services/api/src/index.ts</code>:</p>
|
||||
<ul>
|
||||
<li><code>GET /admin/synthetic/status</code></li>
|
||||
<li><code>GET /admin/synthetic/control</code></li>
|
||||
<li><code>PUT /admin/synthetic/control</code></li>
|
||||
</ul>
|
||||
<pre><code>{
|
||||
enabled: boolean;
|
||||
backend_mode: "synthetic" | "mixed" | "live";
|
||||
adapters: {
|
||||
options: string;
|
||||
equities: string;
|
||||
};
|
||||
control: SyntheticControlState | null;
|
||||
derived: {
|
||||
session_phase: string;
|
||||
regime: string;
|
||||
focus_symbols: string[];
|
||||
profile_hit_counts: Record<SmartMoneyProfileId, number>;
|
||||
coverage_window_minutes: number;
|
||||
} | null;
|
||||
disabled_reason?: string;
|
||||
}</code></pre>
|
||||
<p>Behavior: return <code>404</code> when admin mode is disabled, return <code>409</code> when hosted adapters are not synthetic, validate full payloads on <code>PUT</code>, and keep public smart-money interfaces unchanged.</p>
|
||||
|
||||
<h3>8. Keep secrets out of the browser with Next.js proxy routes</h3>
|
||||
<ul>
|
||||
<li><code>apps/web/app/api/admin/synthetic/status/route.ts</code></li>
|
||||
<li><code>apps/web/app/api/admin/synthetic/control/route.ts</code></li>
|
||||
</ul>
|
||||
<p>The proxy reads server-only <code>SYNTHETIC_ADMIN_TOKEN</code>, forwards to <code>NEXT_PUBLIC_API_URL</code>, returns <code>404</code> when the internal UI flag is off, and never exposes the token client-side.</p>
|
||||
|
||||
<h3>9. Add an internal control surface</h3>
|
||||
<p>UI rules for the first pass:</p>
|
||||
<ul>
|
||||
<li>Small floating gear in the bottom-right corner</li>
|
||||
<li>Opens a right-edge non-modal drawer</li>
|
||||
<li>Internal-only visibility</li>
|
||||
<li>Preset dropdown: <code>Balanced Demo</code>, <code>Event Day</code>, <code>Dealer Day</code>, <code>Retail Chase</code>, <code>Quiet Range</code></li>
|
||||
<li>Coverage assist toggle</li>
|
||||
<li>Coverage window selector: <code>10m</code>, <code>20m</code>, <code>30m</code></li>
|
||||
<li>Six profile-weight controls: <code>Low</code>, <code>Normal</code>, <code>High</code></li>
|
||||
<li>Read-only live status: regime, session phase, focus symbols, rolling hit counts, backend state</li>
|
||||
<li>Optimistic updates with rollback on error</li>
|
||||
<li>Debounced writes at <code>250ms</code></li>
|
||||
<li>Status polling every <code>5s</code>, no admin websocket in v1</li>
|
||||

<li>
|
||||
<strong>Phase 2. Hosted control plane</strong>
|

<p class="subdued">Touch <code>services/api/src/index.ts</code> and NATS or KV helpers as needed. Deliver admin endpoints, KV persistence, status payloads, and disabled or error behavior.</p>
|
||||
</li>
|
||||
<li>
|
||||
<strong>Phase 3. Ingest service coupling</strong>
|
||||
<p class="subdued">Touch both ingest services and their synthetic adapters. Deliver boot-time control loading, KV watch updates, shared regime-driven generation, and removal of visibly scripted fixed sequences.</p>
|

</li>
|
||||
<li>
|
||||
<strong>Phase 4. Internal control UI</strong>
|
||||
<p class="subdued">Touch <code>apps/web/app/terminal.tsx</code> and the internal admin proxy routes. Deliver the floating gear, non-modal drawer, polling, optimistic updates, and disabled state.</p>
|

</li>
|
||||
<li>
|
||||
<strong>Phase 5. Regression and realism tests</strong>
|

<li>The first pass uses polling for admin status rather than a new admin websocket.</li>
|
||||
<li>The default operator experience is <code>Balanced Demo</code> with soft coverage on and a 20-minute window.</li>
|
||||
<li>The repo currently lacks local <code>PRODUCT.md</code>, <code>DESIGN.md</code>, and the local impeccable loader path. This version therefore follows the spirit of the terminal shell and impeccable product-UI principles rather than project-specific design-context files.</li>

<h1>Hosted Synthetic Tape Redesign</h1>
|
||||
<p class="lede">
|
||||
This plan redesigns the hosted synthetic market so the tape feels more like a real market session while still surfacing all six smart-money categories during a demo window. It keeps the public labels stable, adds richer hidden scenario families underneath them, and introduces an internal control surface for shaping the hosted simulator.
|
||||
</p>
|
||||
<div class="summary-grid">
|
||||
<div class="summary-item">
|
||||
<strong>Main outcome</strong>
|
||||
<span>More believable synthetic options, equities, quotes, and smart-money events, with softer coverage guarantees and stronger cross-asset coupling.</span>
|
||||
</div>
|
||||
<div class="summary-item">
|
||||
<strong>User-facing change</strong>
|
||||
<span>An internal-only bottom-right gear opens a compact synthetic-control drawer for operators.</span>
|

</div>
|

<div class="summary-item">
|
||||
<strong>Public API impact</strong>
|
||||
<span>No change to existing smart-money event types or public smart-money endpoints.</span>
|
||||
</div>
|
||||
<div class="summary-item">
|
||||
<strong>Why it matters</strong>
|
||||
<span>The current tape reaches the categories, but it looks too templated and too clean in ways that weaken the demo.</span>

<h2>Simplified Summary</h2>
|
||||
<p>
|
||||
Today the simulator does the important part mechanically: it hits the categories. The problem is that the surrounding market behavior does not always look convincing. Options bursts, equity prints, quote quality, and event timing can feel loosely stitched together instead of driven by one believable market state.
|
||||
</p>
|
||||
<p>
|
||||
The redesign fixes that by introducing a shared regime engine. Both synthetic options and synthetic equities will respond to the same session conditions, such as event ramps, dealer-gamma chop, retail chase, quiet range trading, and neutral arbitrage-heavy periods. The result should be a tape that still teaches the product, but no longer feels obviously scripted.
|
||||
</p>
|
||||
<div class="callout small">
|
||||
The public smart-money taxonomy stays the same: <code>institutional_directional</code>, <code>retail_whale</code>, <code>event_driven</code>, <code>vol_seller</code>, <code>arbitrage</code>, and <code>hedge_reactive</code>.

<h2>Architecture</h2>
|
||||
|
||||
<h3>1. Replace the simple burst pulse with a shared regime engine</h3>
|
||||
<p>Expand <code>packages/types/src/synthetic-market.ts</code> into the shared deterministic market-state engine used by both ingest services.</p>
|
||||
<p>Shared functions:</p>
|
||||
<ul>
|
||||
<li><code>getSyntheticSessionState(ts, control)</code></li>
|
||||
<li><code>getSyntheticUnderlyingState(symbol, ts, control, sessionState)</code></li>
|
||||
<li><code>getSyntheticScenarioWeights(symbol, ts, control, sessionState)</code></li>
|
||||
<li><code>getSyntheticCoverageBoost(profileId, coverageState, control)</code></li>
|
||||
</ul>
|
||||
<p><code>sessionState</code> includes:</p>
|
||||
<ul>
|
||||
<li><code>session_phase</code>: <code>open | midday | power_hour | after_event</code></li>
|
||||
<li><code>regime</code>: <code>trend_up | trend_down | mean_revert | retail_chase | event_ramp | dealer_gamma | arb_calm</code></li>
|
||||
<li><code>volatility_level</code></li>
|
||||
<li><code>liquidity_level</code></li>
|
||||
<li><code>quote_cleanliness</code></li>
|
||||
<li><code>focus_symbols</code></li>
|
||||
<li><code>event_symbols</code></li>
|
||||
<li><code>seed_bucket</code></li>
|
||||
</ul>
|
||||
|
||||
<h3>2. Add hosted synthetic control state</h3>
|
||||
<p>Add internal control schemas in <code>packages/types</code>:</p>
|
||||
<ul>
|
||||
<li><code>SyntheticControlPresetId</code></li>
|
||||
<li><code>SyntheticControlState</code></li>
|
||||
<li><code>SyntheticProfileWeightMap</code></li>
|
||||
<li><code>SyntheticCoverageConfig</code></li>
|
||||
<li><code>SyntheticDerivedStatus</code></li>
|
||||
</ul>
|
||||
<pre><code>type SyntheticControlState = {
|
||||
preset_id: "balanced_demo" | "event_day" | "dealer_day" | "retail_chase" | "quiet_range";
|
||||
coverage_assist: boolean;
|
||||
coverage_window_minutes: 10 | 20 | 30;
|
||||
shared_seed: number;
|
||||
profile_weights: {
|
||||
institutional_directional: 0.6 | 1.0 | 1.6;
|
||||
retail_whale: 0.6 | 1.0 | 1.6;
|
||||
event_driven: 0.6 | 1.0 | 1.6;
|
||||
vol_seller: 0.6 | 1.0 | 1.6;
|
||||
arbitrage: 0.6 | 1.0 | 1.6;
|
||||
hedge_reactive: 0.6 | 1.0 | 1.6;
|
||||
};
|
||||
updated_at: number;
|
||||
updated_by: string;
|
||||
};</code></pre>
|
||||
<p>Defaults:</p>
|
||||
<ul>
|
||||
<li><code>preset_id: balanced_demo</code></li>
|
||||
<li><code>coverage_assist: true</code></li>
|
||||
<li><code>coverage_window_minutes: 20</code></li>
|
||||
<li>All profile weights <code>1.0</code></li>
|
||||
</ul>
|
||||
|
||||
<h3>3. Persist and distribute control state through NATS</h3>
|
||||
<ul>
|
||||
<li>Use JetStream KV bucket <code>synthetic_control</code></li>
|
||||
<li>Use key <code>global</code></li>
|
||||
<li><code>services/api</code> reads and writes the KV entry</li>
|
||||
<li><code>services/ingest-options</code> loads on boot and watches for updates</li>
|
||||
<li><code>services/ingest-equities</code> does the same</li>
|
||||
</ul>
|
||||
|
||||
<h3>4. Rebuild options scenarios as hidden subtype families</h3>
|
||||
<p>Keep public profiles the same, but generate them through richer hidden subtype families.</p>
|
||||
<ul>
|
||||
<li><strong><code>institutional_directional</code></strong>: <code>call_sweep</code>, <code>put_sweep</code>, <code>ask_lift_accumulation</code>, <code>far_dated_conviction</code></li>
|
||||
<li><strong><code>retail_whale</code></strong>: <code>0dte_call_chase</code>, <code>short_dated_put_panic</code>, <code>attention_contract_spike</code></li>
|
||||
<li><strong><code>event_driven</code></strong>: <code>earnings_vol_probe</code>, <code>pre_event_directional_ramp</code>, <code>post_gap_followthrough</code></li>
|
||||
<li><strong><code>vol_seller</code></strong>: <code>covered_call_overwrite</code>, <code>cash_secured_put_write</code>, <code>short_straddle_harvest</code></li>
|
||||
<li><strong><code>arbitrage</code></strong>: <code>parity_vertical</code>, <code>conversion_reversal</code>, <code>box_spread</code></li>
|
||||
<li><strong><code>hedge_reactive</code></strong>: <code>gamma_pinch_call_hedge</code>, <code>reactive_put_wall</code>, <code>dealer_unwind</code></li>
|
||||
<li><strong><code>neutral_noise</code></strong>: <code>single_print_mid</code>, <code>two_sided_scalp</code>, <code>stale_quote_noise</code></li>
|
||||
</ul>
|
||||
|
||||
<h3>5. Make equities and options react to the same latent state</h3>
|
||||
<p>Equities changes:</p>
|
||||
<ul>
|
||||
<li>Remove the fixed dark-sequence loop</li>
|
||||
<li>Make lit versus dark balance regime-dependent</li>
|
||||
<li>Make spread, quote cleanliness, off-exchange frequency, and clustering regime-dependent</li>
|
||||
<li>Use shared focus symbols</li>
|
||||
<li>During <code>event_ramp</code> and <code>retail_chase</code>, create modest trend and wider quotes</li>
|
||||
<li>During <code>dealer_gamma</code>, create choppier reversals and denser quote changes</li>
|
||||
<li>During <code>arb_calm</code>, create quieter underlying motion and more neutral execution context</li>
|
||||
</ul>
|
||||
<p>Options changes:</p>
|
||||
<ul>
|
||||
<li>Replace hardcoded coverage forcing with weighted family selection plus coverage debt</li>
|
||||
<li>Make venue count, placement, stale or missing quote probability, and structure prevalence regime-sensitive</li>
|
||||
<li>Derive <code>execution_iv_shock</code>, <code>underlying_move_bps</code>, and <code>nbbo_spread_z</code> from shared state</li>
|
||||
<li>Generate event-driven timestamps and symbols from shared regime state</li>
|
||||
</ul>
|
||||
|
||||
<h3>6. Add soft coverage accounting</h3>
|
||||
<ul>
|
||||
<li>Track rolling coverage debt per public profile inside each ingest service</li>
|
||||
<li>Maintain a rolling counter across the selected <code>coverage_window_minutes</code></li>
|
||||
<li>Only public profiles count toward coverage</li>
|
||||
<li>Missing profiles get a bounded weight boost</li>
|
||||
<li>Noise and low-key scenarios continue to appear between labeled bursts</li>
|
||||
</ul>
|
||||
|
||||
<h3>7. Add internal hosted control endpoints</h3>
|
||||
<p>Add routes in <code>services/api/src/index.ts</code>:</p>
|
||||
<ul>
|
||||
<li><code>GET /admin/synthetic/status</code></li>
|
||||
<li><code>GET /admin/synthetic/control</code></li>

<h2>Implementation Sequence</h2>
|
||||
<ol>
|
||||
<li>
|
||||
<strong>Phase 1. Shared types and regime engine</strong>
|
||||
<p class="muted small">Touch <code>packages/types/src/synthetic-market.ts</code> and related exports and tests. Deliver control schemas, preset definitions, deterministic session and regime functions, and coverage boost helpers.</p>
|
||||
</li>
|
||||
<li>
|
||||
<strong>Phase 2. Hosted control plane</strong>
|
||||
<p class="muted small">Touch <code>services/api/src/index.ts</code> and NATS or KV helpers as needed. Deliver admin endpoints, KV persistence, status payloads, and disabled or error behavior.</p>
|
||||
</li>
|
||||
<li>
|
||||
<strong>Phase 3. Ingest service coupling</strong>
|
||||
<p class="muted small">Touch both ingest services and their synthetic adapters. Deliver boot-time control loading, KV watch updates, shared regime-driven generation, and removal of visibly scripted fixed sequences.</p>
|
||||
</li>
|
||||
<li>
|
||||
<strong>Phase 4. Internal control UI</strong>
|
||||
<p class="muted small">Touch <code>apps/web/app/terminal.tsx</code> and the internal admin proxy routes. Deliver the floating gear, non-modal drawer, polling, optimistic updates, and disabled state.</p>
|
||||
</li>
|
||||
<li>
|
||||
<strong>Phase 5. Regression and realism tests</strong>
|
||||
<p class="muted small">Deliver determinism tests, control API tests, scenario coverage tests, UI visibility tests, and classifier-alignment tests for hidden subtype families.</p>

||||

|

<h2>Test Cases and Scenarios</h2>
|
||||
<h3>Shared engine</h3>
|
||||
<ul>
|
||||
<li>Same <code>timestamp + control snapshot + seed</code> yields the same regime and focus symbols in both ingest services.</li>
|
||||
<li>Presets materially change regime weights without breaking determinism.</li>
|
||||
<li><code>balanced_demo</code> yields mixed regimes over a session.</li>
|
||||
<li><code>quiet_range</code> yields lower volatility, tighter spreads, and fewer labeled events than <code>retail_chase</code>.</li>
|
||||
</ul>
|
||||
<h3>Cross-asset coupling</h3>
|
||||
<ul>
|
||||
<li><code>event_ramp</code> produces event-aligned option scenarios and synchronized underlying drift and spread behavior.</li>
|
||||
<li><code>dealer_gamma</code> produces short-dated ATM-heavy options plus choppier underlying reversals.</li>
|
||||
<li><code>arb_calm</code> increases neutral multi-leg structures without strong directional underlying moves.</li>
|
||||
<li><code>retail_chase</code> increases short-dated OTM call behavior, IV shock, and louder underlying momentum.</li>
|
||||
</ul>
|
||||
<h3>Coverage behavior</h3>
|
||||
<ul>
|
||||
<li>With default controls, every public smart-money profile appears at least once in a 20-minute synthetic session sample.</li>
|
||||
<li>With <code>coverage_assist=false</code>, there is no forced coverage logic.</li>
|
||||
<li>Raising one profile to <code>High</code> increases its frequency without starving all other categories.</li>
|
||||
<li>The quiet preset still emits noise and occasional signals rather than a dead tape.</li>
|
||||
</ul>
|
||||
<h3>Classification alignment</h3>
|
||||
<ul>
|
||||
<li>Each hidden subtype family still classifies primarily into its intended public profile.</li>
|
||||
<li>Neutral noise remains below the smart-money emission threshold.</li>
|
||||
<li>Nearby wrong profiles stay below threshold in subtype template tests.</li>
|
||||
</ul>
|
||||
<h3>Admin API and UI</h3>
|
||||
<ul>
|
||||
<li>Disabled admin mode returns <code>404</code>.</li>
|
||||
<li>Non-synthetic hosted mode returns <code>409</code> with a useful reason.</li>
|
||||
<li>Valid <code>PUT</code> persists to KV and becomes visible to both ingest services.</li>
|
||||
<li>The floating gear is hidden when <code>NEXT_PUBLIC_SYNTHETIC_ADMIN</code> is off.</li>
|
||||
<li>The browser client never receives the backend admin token.</li>
|
||||
</ul>

||||

<section id="assumptions">
|
||||
<h2>Assumptions and Defaults</h2>
|
||||
<ul>
|
||||
<li>Hosted synthetic control applies only when both options and equities ingest adapters are synthetic.</li>
|
||||
<li>No general settings page, user-info work, or token-spend work is in scope here.</li>
|
||||
<li>Hidden subtype labels remain internal and test-only and never attach to emitted prints.</li>
|
||||
<li>The first pass uses polling for admin status rather than a new admin websocket.</li>
|
||||
<li>The default operator experience is <code>Balanced Demo</code> with soft coverage on and a 20-minute window.</li>
|
||||
<li>The repo currently lacks local <code>PRODUCT.md</code>, <code>DESIGN.md</code>, and the local impeccable loader path, so UI implementation should use the existing terminal shell as the visual source of truth unless those design-context files are added later.</li>
