agent_access_status

Identity, current entitlement, daily usage and access instructions; explains missing/refused subscriber tools.

crypto_exit_check

Compare four BTC sell sizes by rung/bracket. Withholds stale/future, uncovered or unconverted venues. Fees excluded; no trade clearance.

crypto_funding_cost

Caller-input perpetual funding, fees, net carry and linear break-even. Positive funding: longs pay shorts. Constant-rate scenario, not forecast.

crypto_portfolio_stress

Caller-input linear shocks for 20 exposures: P&L, equity, asset/venue concentration. Symbols are scenario labels. No liquidation/probability model.

depth_episodes

Realized BTC depth-collapse onset, trough, recovery under preregistered rules. Zero is distinct from missing. Subscriber exit_desk_full adds ETH.

exit_cost

BTC nearest-rung sell estimates, interpolated bid-depth bands; fees excluded, not executable. crypto_exit_check compares sizes/freshness.

gold_cash_realisation

Calculate gold sale proceeds and cash gates from caller inputs. Decimal strings: kg, fineness (0,1], USD/troy-oz bid, USD fees, currency/USD FX (USD=1). Use aware ISO clocks. Returns arithmetic and wi…

latest_article

Read the latest published editorial: title, full text, URL, clock and quality receipt. No arguments. Missing text or failed receipt returns an error; no generated prose. Use liquidity_tiers for board …

liquidity_tiers

Nine segment tiers, Seiche funding, measure counts and replay/withholding reasons. PARTIAL means missing history or unpassed replay, never calm.

market_corpus_context

Inspect corpus coverage, rights and clocks. Summary takes no pagination; other views return records/total/next_offset. Retrieval age is not observation freshness. Use liquidity_tiers for market readin…

research_network

Find cross-product source metadata, clocks, rights and next steps. Follow next_offset; unavailable flags retrieval, contract or size failure. Use market_corpus_context for local corpus counts. No shar…

sealed_record

Forward calls sealed/signed before outcomes: hits, misses, decided counts, ledger root. Report hits and misses together.

trade_safety_exit_context

Exact-rung BTC/USD observe/paper context: request hash, PIT source/rights, conversion, bid bands, six venue clocks, startup SHA. No live mode or clearance.

unwind_watch

Watched-filer headlines: effective positions, days-to-exit brackets, blind spots. No live execution model. unwind_stress has full scenario grids.

venue_concentration

BTC two-sided depth: HHI, effective/top venue and venue depth. Subscriber exit_desk_full adds ETH and venue failure.

venue_price_reconciliation

BTC/ETH consensus: depth/squared-half-spread weights, deepest-venue blindness, concentration, dislocations. Experimental; no execution authority.

can_this_book_exit

Unwind stress for the watched books: door width versus position size, margin clock, and what changed this quarter.

exit_cost_check

Venue-by-venue exit cost for a position size, with concentration and consensus-price context and the caveats stated.

market_liquidity_briefing

The full board read: tier per segment, realized depth episodes, and the sealed forward-calls record with misses quoted.
