v17.2.8

@oh-my-pi/pi-coding-agent

Changed

• Upgraded the bundled omptype schema engine: intersection and pipe operators, bigint and RegExp literals in the string DSL, Standard Schema V1 interop, JSON Schema import via fromJsonSchema(), and richer union/collection error reporting.

@oh-my-pi/omptype

Added

• Added io: 'input' and io: 'output' options to toJsonSchema(), supporting input validation shapes and piped .to() target types
• Added Standard Schema V1 interop: every schema exposes ~standard with synchronous validation, enabling direct use with @t3-oss/env, tRPC, and other Standard Schema consumers.
• Added fromJsonSchema(), rebuilding callable schemas from JSON Schema documents (draft-07 / draft-2020-12 structural keywords, string formats, $defs recursion, enums, and anyOf/oneOf/allOf composition) — the inverse of Type.toJsonSchema().
• Added $defs/$ref emission for recursive alias schemas in toJsonSchema() (draft-07 converts to definitions), preventing unbounded recursion on cyclic scopes.
• Added AnyType, a minimal structural constraint for generic functions accepting any schema without descending the recursive fluent surface.
• Root .default() values now materialize for undefined input in direct calls and at the Standard Schema boundary (factories run per call).
• .narrow()/.filter() boolean overloads accept OmpErrors returns, so cond || ctx.reject(...) recipes typecheck.

Changed

• Restored low-overhead schema construction by lazily activating advanced normalization and compatibility machinery.
• .default() is typed input-side (i | (() => i)) and marks the schema's input as optional (i | undefined).
• Parse keywords (string.integer.parse, parse.number, ...) now infer their morph output inside union strings, and input-side inference is union-aware.
• Object-literal inference for .merge()/.or()/.and() unwraps embedded schema values (output and input sides).

Fixed

• Alias intersections defer through memoized lazy nodes, so cyclic scope schemas no longer overflow the stack in .and() or morph-union determinism checks.
