v1.4.0

Lint

• 21 new CLOS, condition-system, and iteration lint rules (#81).
• 8 new REPL-debug-leftover lint rules catching stray print/describe/trace-style debugging calls (#78).
• Macro hygiene checks are now enforceable (not just report-only) across all eight dialects, with 4 new checks and a scoped auto-fix (#71, #79).
• lint-custom (defrule) gained dialect scoping, pattern fragments, self-collision detection, and per-rule timing (#68).
• defrule's pattern language is now unified with the --query/--rewrite engine — the same pattern syntax works in both places (#62).
• inspect lint --suggest-severity advises when a rule's observed finding density disagrees with its configured severity (#57).
• Custom-rule parity: --test-rules JSON, --docs, and --explain now cover custom rules the same as built-in ones (#58); loaded custom rules are recognized by lint.enable/disable/deny/warn (#61); config check detects custom-rule severity conflicts (K7).
• 9 additional lint rules from Section C, part 1 of 13 (#66).

Format

• paredit.toml gained a project-overridable indent table, width profiles, and quote style (#74).
• Section J: numeric-case normalization, clause alignment, auto-width, and .editorconfig support (#77).
• Trailing-comment alignment and blank-line normalization (#69).
• Fixed width counting, added diff-stat aggregation, and block-comment reindent (#67).

New commands and surfaces

• inspect data-check and edit kill-ring (Phase 0), with a --format flag and 5 format-specific detectors added to data-check (Phase 1).
• edit canonicalize normalizes alist/plist data files, refusing files that carry a comment to avoid silently dropping it (K10, plus a follow-up fix).
• A schema namespace with a defschema DSL (Phase 4); config check rejects duplicate spec keywords and documents :optional.
• Named checkpoints for refactor state (FR-008).
• --explain-error and inline ambiguous-selector candidates on refusal (FR-001, FR-002).
• refactor plan/apply gained a risk aggregate, next-command chaining, a compact headline, and grouped apply output (FR-003–007).
• PAREDIT_CACHE_DIR and cache.dir config layering (FR-012).

Semantic analysis

• Type inference widened to Emacs Lisp, Scheme, and Racket (FR-002, FR-003).
• Effects analysis widened to Emacs Lisp (FR-005); contradiction detection widened to Elisp/Scheme/Racket (FR-007).
• Value-layer constant folding/propagation widened to Emacs Lisp and fed into effect purity (FR-004, FR-008/A11).
• Per-dialect --fail-under-dialect coverage thresholds (semantic-coverage).
• The six semantic introspection commands report per-layer dialect granularity in inspect capabilities (FR-001).
• defmethod binds its parameters, not its specializers, in the semantic model (FR-009).
• Read-time-eval handling made cross-dialect (Phase 2).

Agent/MCP experience

• MCP now surfaces write outcome and carries trimmed tool descriptions (FR-009/FR-010).
• inspect capabilities reports a per-command writes flag and each command's possible error codes (FR-011).
• Closed a gap where two newer write commands were missing from MCP's --read-only gate; fixed an apply/diff conflict.

Accessibility

• Output-wide accessibility: NO_COLOR consistency, verbosity levels, plain-language errors (#54).
• TERM=dumb/FORCE_COLOR handling, an HTML palette, screen-reader-friendly structure, JSON envelope pinning, and CJK-aware clipping (#60).

Performance

• Dynamic scheduling, a Node struct size reduction, and a redundant-parse fix for the highest-risk performance/scale items (#76).
• Lower-risk performance/scale gap fixes across the engine (#64).

Fixes

• config's custom_conflicts reads now go through the bounded reader.
• data-check no longer misclassifies typed/racket-flavored files as racket-data.

No commands, flags, or JSON fields were removed or renamed since v1.3.0 — this is a purely additive minor release.
