Narrow ADR-0036 from "bind literals via the DSL path" to "validate literal
values (shared validators) + retain them; execute verbatim, keep auto-fill
and command identity mode-specific" — after a concrete auto-fill difference
(non-PK serial) confirmed the modes aren't identical even for single-row
literals. Augments (no longer supersedes) ADR-0030 §4 / ADR-0033 §10;
Amendment 3 stands. README + forward-notes on 0030/0033 updated. Records
requirements.md X4 (serial auto-fill — possible bug) and X5 (framework
cohesion / share-mechanics-not-commands).
Records the decision that advanced-mode SQL DML should stop handing literal
data values to the engine as text and instead parse/validate/bind them
through the DSL's proven path — closing the value-validation gap, the
hint/highlight gap, and the offending-value-in-errors gap together. Verbatim
text stays for expressions, WHERE, INSERT…SELECT, and SELECT (full SQL
surface preserved; ADR-0026's limited Expr not imposed). Narrows ADR-0030 §4
/ ADR-0033 §10 once accepted; SELECT half of §4 stands.
Includes a characterization test (tests/sql_insert.rs) proving the bind-layer
gap: the DSL rejects the malformed date 2025/01/15, advanced-mode SQL accepts
it. Forward-notes added to ADR-0030/0033; README index updated.
Status: Proposed (design + /runda done; pending go-ahead to implement).
Decides the architecture for SQL in advanced mode (Q1/Q2/Q4):
SQL is authored as grammar within the unified grammar tree
(ADR-0024) and parsed by the existing walker — not a separate
batch parser — so SQL gets the same completion, highlighting,
hints, and parse-error reporting as the DSL. Mode gates the
SQL forms. DDL routes through the typed Command executor
(metadata and the playground type vocabulary preserved); DML
and SELECT execute as validated SQL. Engine-neutral posture;
DSL→SQL teaching echo; phased plan.
Supersedes ADR-0001's sqlparser-rs reservation. Ticks Q4;
updates the ADR index and the Q1/Q2 notes. handoff-24 orients
the implementation session at Phase 1.
