`register-market`

Register a MarketLink in the shared MarketRegistry. Two kinds:

  --question "Will BTC close above \$100k on Jun 30, 2026?" \
  --oracle-svi 0x... \
  --expiry 1719792000000 \
  --category crypto \
  --execute

# Optimistic-oracle market (sports / politics / geopolitics)
pnpm market:register --kind oo \
  --question "Will a European team win the 2026 World Cup?" \
  --event-end-ms 1721433600000 \
  --category sports \
  --execute

Flags

Flag	Required	Description
`--kind`	yes	`price` or `oo`
`--question`	yes	Human-readable text
`--category`	yes	`crypto` \| `sports` \| `politics` \| `geopolitics` \| `macro`
`--oracle-svi`	for price	Predict OracleSVI id
`--expiry` / `--event-end-ms`	yes	Unix ms timestamp
`--spec-blob-id`	no	Walrus blob id of long-form rules (default: empty)
`--spec-hash`	no	blake2b hash of spec blob (default: zeros)
`--execute`	no	Sign + submit

Captures the MarketLink id from objectChanges and suggests the .env key (BTC_MARKET_LINK_ID for price, SPORTS_OO_MARKET_LINK_ID for OO).

`create-seal-policy`

Creates + shares a fresh seal_policy::AccessPolicy on the current package. dark_pool::deposit takes &AccessPolicy of the deployed package’s type, so every republish needs a fresh one.

pnpm tsx scripts/create-seal-policy.ts --execute

Paste the id into both:

.env: AGENT_SEAL_POLICY_ID=0x…
packages/frontend/src/lib/env.ts: DEFAULT_SEAL_POLICY_ID = '0x…'

The vault deposit PTB always passes this policy as an opaque argument.
