v0.7.0

Minor Changes

• #84 e003218 Thanks @SutuSebastian! - symbols.kind distinguishes const / let / var instead of collapsing all three into 'const'. Schema bump SCHEMA_VERSION 26 → 27 — first run after upgrade auto-rebuilds .codemap/index.db via the existing version-mismatch path; consumer queries see the new values immediately.

  What changes:

  • let x = 1 now emits kind = 'let' + signature = 'let x'.
  • var y = 2 now emits kind = 'var' + signature = 'var y'.
  • const z = 3 unchanged (kind = 'const' + signature = 'const z').
  • Destructuring patterns inherit the declaration keyword: let { a, b } = obj → both a and b are kind = 'let'.
  • for (let x of arr) { ... } body bindings inherit the keyword (kind = 'let').
  • Arrow / function init still wins over the keyword: const handler = () => 1 and let handler = () => 1 both emit kind = 'function'.

  Breaking — but pre-v1 the breakage IS the fix. Any query that filtered WHERE kind = 'const' to mean “all variable bindings” was silently over-matching every let and var. Post-upgrade the filter is precise; queries that wanted the over-match should widen to WHERE kind IN ('const', 'let', 'var'). Affected paths in this PR: the 40-query-patterns.md const-values example (now demonstrates the precise filter + adds two new patterns that depend on it — “lets that should be const” and “consts that get illegally written”), and find-write-sites.md prose where the recipe’s documented JOIN trick now works as described.

  Mutability filters that finally work:

  -- bindings declared `let` but never reassigned — candidates to tighten to `const`
  SELECT s.name, s.file_path, s.line_start FROM symbols s
  WHERE s.kind = 'let'
    AND NOT EXISTS (
      SELECT 1 FROM "references" r
      WHERE r.name = s.name
        AND r.file_path = s.file_path
        AND r.is_write = 1
        AND r.line_start > s.line_start
    );
  
  -- `const`s that get reassigned anyway (TypeScript usually catches it; queryable here for completeness)
  SELECT s.name, s.file_path, s.line_start FROM symbols s
  JOIN "references" r ON r.name = s.name AND r.file_path = s.file_path
  WHERE s.kind = 'const' AND r.is_write = 1 AND r.line_start > s.line_start;

  find-symbol-by-kind recipe params updated to enumerate the new values explicitly.

  file_metrics keyword counts populate too — let_count / const_count / var_count were previously hardcoded to 0 (// let/const/var distinction not yet tracked per the in-source TODO). They now reflect the actual per-file counts. docs/architecture.md § file_metrics drops the “Reserved (parser-keyword variant TBD)” notes.
