The C5a design: a stratified, recursive WHERE-expression grammar (AND/OR/NOT, comparisons, LIKE, IS NULL, IN, BETWEEN) for update / delete / show-data filters; show data gains optional `where` and `limit`. Adds the `Subgrammar` reference-following grammar node and a recursive `Expr` AST, built selectively for the expression fragment. - docs/adr/0026-complex-where-expressions.md — the ADR. - docs/adr/README.md — index entry. - docs/simple-mode-limitations.md — new running list of simple-mode query boundaries vs. advanced SQL, seeded from ADR-0026. - docs/requirements.md — C5a [~] -> [ ] (designed, not yet implemented); new Documentation section with DOC1.

- ADR-0024 — Unified grammar tree: execution plan — Accepted, the executable spec — implemented (Phases A–F; Phase F shipped "minimal",
parser.rsretained as the router — see the ADR's Phase F implementation note) - ADR-0025 — Indexes — Accepted,
add index/drop index, persistence, rebuild-table preservation, and items-list display (C3index portion +S2) - ADR-0026 — Complex WHERE expressions — Accepted, stratified recursive expression grammar (
AND/OR/NOT, comparisons,LIKE,IS NULL,IN,BETWEEN) forupdate/delete/show datafilters;show datagainswhere+limit; adds theSubgrammarnode and a recursiveExprAST (C5a)
