src/core/json — the hand-rolled JSON lexical layer

Scope

The ONE hand-rolled JSON lexical layer used across the pure core: string/number/ bool/null tokens, the scoped object Writer, and the bounds-checked Reader cursor. Domain grammars — what fields a bank, view-mode, or manifest blob actually has — stay in the consumers; this module owns lexing/emitting only.

Modules

• json (core/json) — the ONE hand-rolled JSON lexical layer (Q-W1): string/number/bool/null tokens, the scoped object Writer, and the bounds-checked Reader cursor, byte-compatible with the five pre-extraction per-module writers it replaced (bank_model / bank_book / view_mode_model / the retired owned_manifest, now core/tracking/origin_ledger / tail_control). Domain grammars stay in the consumers; this owns lexing/emitting only.

Gotchas

• Byte-compatible with the five pre-extraction per-module writers it replaced (bank_model / bank_book / view_mode_model / the retired owned_manifest / tail_control) — a change here risks silently breaking round-trip compatibility with ext-state blobs already persisted by projects written before the Q-W1 extraction.
