2026-10-09market_corpus_contextchangeddescriptionmeaning changed
before
Corpus counts, rights and clocks; summary or bounded dataset/flow/export pages. Retrieval is not observation freshness. Context only.
after · 26% of words in common
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 readings.

before
Exact published Undertow editorial, evidence clock and passing quality receipt.
after · 18% of words in common
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 data.

Caller-input gold/FX sale scenario and separate cash-at-cutoff gates: quote freshness/expiry, cleared settlement, access and pledge. Decimal strings; aware ISO clocks. No verified balance or executable quote.
after · 31% of words in common
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 withheld-cash reasons; no fetch, storage, execution or verified balance.

Tools (16)

`agent_access_status`read-only	Identity, current entitlement, daily usage and access instructions; explains missing/refused subscriber tools.
`crypto_exit_check`read-only	Compare four BTC sell sizes by rung/bracket. Withholds stale/future, uncovered or unconverted venues. Fees excluded; no trade clearance.
`crypto_funding_cost`read-only	Caller-input perpetual funding, fees, net carry and linear break-even. Positive funding: longs pay shorts. Constant-rate scenario, not forecast.
`crypto_portfolio_stress`read-only	Caller-input linear shocks for 20 exposures: P&L, equity, asset/venue concentration. Symbols are scenario labels. No liquidation/probability model.
`depth_episodes`read-only	Realized BTC depth-collapse onset, trough, recovery under preregistered rules. Zero is distinct from missing. Subscriber exit_desk_full adds ETH.
`exit_cost`read-only	BTC nearest-rung sell estimates, interpolated bid-depth bands; fees excluded, not executable. crypto_exit_check compares sizes/freshness.
`gold_cash_realisation`read-only	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 withheld-cash reasons; no fetch, storage, execution or verified balance.
`latest_article`read-only	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 data.
`liquidity_tiers`read-only	Nine segment tiers, Seiche funding, measure counts and replay/withholding reasons. PARTIAL means missing history or unpassed replay, never calm.
`market_corpus_context`read-only	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 readings.
`research_network`read-only	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 shared score or authority.
`sealed_record`read-only	Forward calls sealed/signed before outcomes: hits, misses, decided counts, ledger root. Report hits and misses together.
`trade_safety_exit_context`read-only	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`read-only	Watched-filer headlines: effective positions, days-to-exit brackets, blind spots. No live execution model. unwind_stress has full scenario grids.
`venue_concentration`read-only	BTC two-sided depth: HHI, effective/top venue and venue depth. Subscriber exit_desk_full adds ETH and venue failure.
`venue_price_reconciliation`read-only	BTC/ETH consensus: depth/squared-half-spread weights, deepest-venue blindness, concentration, dislocations. Experimental; no execution authority.
