fix(create-market): v17 detection must fail closed, not silently downgrade to v12 - #2524
Conversation
…grade to v12 The probe initialised isV17Slab to false and swallowed read errors, so ANY failure to confirm v17-ness routed a v17 market down the legacy v12 branch. That branch calls sdk-compat stubs which THROW by design -- the instructions were removed on-chain in beta.29 -- so the user saw an opaque "[sdk-compat] ... removed in beta.29" describing an SDK migration rather than what actually went wrong. The slab is created moments earlier in the same flow, so getAccountInfo returning null is an ordinary propagation race, not an exceptional case. That made the bad branch reachable in normal operation whenever admin-oracle mode was selected. Now: tri-state (boolean | null), up to 5 reads at "confirmed" with backoff, and if v17-ness still cannot be established the flow stops with a message naming the account and stating that nothing further was sent. Failing closed is correct here because the alternative branch is known to throw. Fixes #2523. app tsc: 0 errors.

Validate the v12 slab format before setting isV17Slab to false.
When isAdminOracle is true and the RPC returns readable data that is neither V17 nor valid v12 data, isV17Account returns false and the legacy sdk-compat encoder throws. Call parseHeader before assigning false; keep isV17Slab unset when parsing fails so the retry loop does not select the legacy path.
