The agent patch appears to implement the core intended behavior: it adds a dedicated nested-bracket lookahead in the dialect and a distinct tokenizer path for `["..."]`, resolving ambiguity with `[0]`-style JSON/array access and enabling quoted numbered columns. It does not mirror the gold refactor structure (it keeps existing bracket identifier logic for `[foo]` in the older path), but behaviorally it addresses the task’s parsing intent.
Code Review
Patch direction is related but does not faithfully implement the intended nested-delimited identifier design; it likely leaves the original ambiguity only partially resolved and carries elevated regression risk.
Bracket identifier handling remains partly in the existing delimited-identifier path and partly in a new `[`-specific path, so the parser logic is still entangled instead of being cleanly separated by dialect quote-peek rules.
The new dialect hook returns only a boolean over a character iterator, so tokenizer must hardcode quote characters and cannot receive structured `(outer, inner)` quote information needed for a general nested-delimiter decision.
The added redshift probe only checks for `[` followed by optional whitespace and `"`, so only `["]` style nested quoting enters the new path; plain `[foo]` is not covered by the same mechanism, leaving behavior dependent on legacy heuristics.
The tokenizer branch directly encodes bracket and double-quote parsing/error handling, which duplicates quoted-identifier logic and makes future dialect behavior changes harder to evolve safely.
