LIKE is a text-pattern match; against a numeric column (int,
real, decimal, serial) it runs but is almost never intended.
predicate_warnings now emits a WARNING for it, spanned at the
target column. New Type::is_numeric; catalog key
diagnostic.like_numeric; ADR-0027 gains "Amendment 1" and the
adr/README index line is updated per the index-upkeep rule.
bool and the text-/blob-backed types are deliberately not
flagged — see the amendment for the rationale.
3 walker tests (int, decimal NOT LIKE, text-column clean).
1108 passing, clippy clean.
Sweep: input_verdict tests confirm the schema-existence check
fires across the identifier-taking commands — unknown table
on drop / show / add column, unknown column on drop column /
update — and that known references stay clean. The Step B
check is grammar-generic, so this is verification + coverage
rather than new code.
Docs: requirements.md S6 -> [x], baseline 1096; CLAUDE.md
deferred list reconciled (C5a and S6 are done — removed);
ADR-0026's as-built note updated (step 5 shipped via
ADR-0027); ADR-0027 gains an As-built notes section
recording the post-walk diagnostics realization, the
pre-rendered message, the timeout-based debounce, coarse
WARNING spans, and the deferred highlight/hint wiring.
A debounced `[ERR]` / `[WRN]` marker at the right edge of
the input row, summarising — before submit — whether the
current command would run. Backed by a small
diagnostics-severity model: the walker emits severity-
tagged diagnostics (parse outcome, schema-existence of
table / column names) that the indicator summarises and
the existing highlighting / hint layers detail. Advisory
only — submission is never blocked.
- docs/adr/0027-input-validity-indicator.md — the ADR.
- docs/adr/README.md — index entry.
- docs/requirements.md — new S6 (TUI shell).
