0.8.90

Added

• Added live-verify eval pack cases with a generic executor command interface,
  verify-command checks, expected output validation, and trial-level ledger
  resume.

Changed

• Refactored harn eval coding-agent fixtures into portable live-verify eval-pack cases
  with trial ledger resume while preserving existing coding-agent reports.

Fixed

• Fixed the direct Anthropic provider sending tool_choice as a bare string
  (the OpenAI wire shape), which Anthropic rejected with HTTP 400
  (tool_choice: Input should be an object) and broke tool-using agent loops on
  --provider anthropic. Harn's tool-choice modes are now mapped to Anthropic's
  object form (auto/any/none/specific-tool), and OpenAI-style
  {"type":"function",...} and bare-name inputs are normalized too.
• Reverted the v0.8.89 "untyped NULL (OID 0)" Postgres nil bind. Binding
  nil as an unspecified-type NULL (OID 0) so Postgres infers the slot type
  from context is incompatible with sqlx's binary wire protocol: when a query
  mixes a nil param with non-null typed params, Postgres re-infers the whole
  parameter-type list from the OID-0 slot during Parse, and the inferred
  types no longer match the client-declared OIDs sqlx encodes the non-null
  params with — yielding incorrect binary data format in bind parameter N /
  insufficient data left in message (and could not determine data type in
  genuinely ambiguous contexts). nil once again binds as None::<String>
  (Postgres TEXT), the long-stable behavior. The narrow cache-poisoning /
  typed-column cases the OID-0 change targeted are handled at the query layer by
  binding a concrete cast ($n::text::int, a ::text cast, or a non-null
  sentinel) — the correct place to disambiguate a NULL's intended type.
• Fixed the Postgres hostlib binding a non-finite Float (NaN/Infinity) raw:
  a direct float8 bind stored NaN/Infinity (which breaks downstream JSON), and
  a non-finite float on the jsonb path serialized to a silent JSON null.
  pg_query/pg_execute (and the introspection/advisory helpers) now reject a
  non-finite float — directly bound or nested in a list/dict — with a clear
  error before it reaches the database. Finite-float binds are unchanged.
