+## [1.5.3] - 2026-05-02
+
+### Added
+
+- Published the read-only `memory-diag` package binary for package-qualified `npx --package opencode-working-memory memory-diag` usage.
+- Added user-facing diagnostics commands for concise status, rejected memory review, missing memory review, and per-memory explanation.
+
+### Changed
+
+- Reworked the diagnostics CLI into focused command, model, formatter, and utility modules while preserving legacy aliases and maintainer diagnostics.
+- Updated README and configuration docs to document the supported `memory-diag` CLI workflow and package-qualified `npx` usage.
+- Raised the Node.js requirement to `>=22.6.0` for the TypeScript diagnostics CLI runtime.
+
+### Fixed
+
+- Avoided repeated workspace snapshot construction in status diagnostics.
+- Replaced per-memory evidence summary lookups with grouped evidence processing to avoid N+1 diagnostics work.
+- Added top-level CLI error handling for cleaner user-facing failures.
+- Removed a diagnostics model circular dependency by extracting evidence grouping helpers to a neutral module.

 # Release Notes
 
+## 1.5.3 (2026-05-02)
+
+### Published Memory Diagnostics CLI
+
+This release makes the read-only workspace memory diagnostics CLI available as the package binary `memory-diag`, with user-facing commands for checking memory health and understanding why memories are rejected, missing, shown, or hidden.
+
+> Good memory is selective memory — and diagnostics should explain the selection.
+
+### What Changed
+
+- **Published CLI bin**: run diagnostics with `npx --package opencode-working-memory memory-diag` or `memory-diag status`.
+- **User-facing commands**: `status`, `rejected`, `missing`, and `explain <memory-id>` are documented as the supported public workflow.
+- **Legacy compatibility**: existing maintainer and legacy commands remain accepted with deprecation notices where applicable.
+- **Cleaner CLI architecture**: the former monolithic diagnostics script is now split into focused command, model, formatter, and utility modules.
+- **Faster diagnostics**: evidence grouping avoids repeated per-memory evidence queries in snapshot diagnostics.
+- **Cleaner failures**: top-level CLI error handling now reports usage and unexpected command errors without noisy stack traces.
+- **Docs alignment**: README and configuration docs now use package-qualified `npx` commands to avoid resolving an unrelated package named `memory-diag`.
+
+### Requirements
+
+- Node.js `>=22.6.0` is now required because the published diagnostics binary runs TypeScript through Node's `--experimental-strip-types` support.
+
+### Validation
+
+- `npm run typecheck` — `TYPECHECK_PASS`
+- `npm test` — 358 tests passing, `TEST_PASS`
