docs(release): prepare v1.6.3

Add memory-diag quality command for objective review of memory-system
mechanisms and active memory content. The command is read-only and
non-authoritative, providing evidence, heuristic flags, and review
questions without making quality judgments or suggesting mutations.

Key components:
- quality-review-model.ts: builds ReviewBoardReport with provenance,
  re-absorption detection, mechanism facts (rejection, reinforcement,
  eviction/caps, identity/dedup), and memory content facts
- formatters/quality.ts: human and JSON output with separate
  system-mechanism and memory-content sections
- commands/quality.ts: command entry point with --json, --verbose,
  --no-emoji, --raw options
- cli.ts: parser whitelist for quality accepting --workspace, --json,
  rejecting mutation/filter flags

+## [1.6.3] - 2026-05-14
+
+### Added
+
+- Added `memory-diag quality`, a read-only review board for memory-system mechanism evidence, answerability levels, provenance classification, active-memory review surfaces, and JSON review output.
+- Added producer/version-aware diagnostic facts so current instrumentation can be separated from historical or unversioned evidence when reviewing reinforcement, rejection, and eviction patterns.
+- Added `memory-diag commands --memory <memory-id>` for focused reinforcement command detail, including current memory status, recorded block reasons, missing block detail counts, UTC-day evidence, and privacy-safe JSON.
+
+### Changed
+
+- Made `activeMemoryDisplay` the canonical active-memory review surface in `memory-diag quality` JSON and removed duplicate active-memory `reviewCandidates` entries.
+- Clarified diagnostic provenance and answerability wording so `memory-diag quality` separates facts, heuristic flags, review questions, and human judgment requirements.
+
+### Fixed
+
+- Removed duplicate active-memory candidate construction from `memory-diag quality` to prevent drift between human output and JSON surfaces.
+- Kept reinforcement detail diagnostics evidence-only so blocked reinforcement attempts are shown as recorded evidence without claiming policy failure or memory loss.

 # Release Notes
 
+## 1.6.3 (2026-05-14)
+
+### Diagnostic Quality Review Board
+
+This patch release focuses on safer memory diagnostics. It adds a read-only quality review board and finer reinforcement drill-downs so reviewers can inspect memory-system evidence without treating historical artifacts as current failures or turning heuristic flags into automatic cleanup decisions.
+
+The goal is better observability before policy changes: diagnostics show facts, provenance, answerability, and review questions, while leaving judgment to the operator.
+
+### What Changed
+
+- **Quality review board**: `memory-diag quality` now reports system-mechanism facts for rejection filters, reinforcement rules, eviction/caps, identity/dedup, and active memory content review.
+- **Version/provenance context**: diagnostics distinguish current producer-instrumented events from historical or unversioned evidence where possible, and label ambiguous evidence conservatively.
+- **Focused reinforcement drill-down**: `memory-diag commands --memory <memory-id>` shows one memory's reinforcement command evidence, current status, recorded block reasons, missing details, and UTC-day evidence.
+- **Canonical active-memory JSON surface**: `memory-diag quality --json` now uses `activeMemoryDisplay` as the single active-memory review surface instead of duplicating active memories under `reviewCandidates`.
+- **Attribution-safe wording**: quality and reinforcement diagnostics avoid claiming that a block is a bug, policy failure, or cause of memory loss; they present recorded evidence and review prompts instead.
+
+### Upgrade Notes
+
+- No configuration changes are required.
+- Existing workspace memory files and evidence logs remain compatible.
+- If you consume `memory-diag quality --json` from unreleased builds after v1.6.2, read active-memory review data from `activeMemoryDisplay`; `reviewCandidates` is now reserved for system-mechanism candidates.
+
+### Useful Commands
+
+```bash
+npx --package opencode-working-memory@1.6.3 memory-diag quality
+npx --package opencode-working-memory@1.6.3 memory-diag quality --json
+npx --package opencode-working-memory@1.6.3 memory-diag commands --memory <memory-id>
+```
+
+### Validation
+
+- `node --test --experimental-strip-types tests/memory-diag-quality.test.ts` — 53 tests passing
+- `node --test --experimental-strip-types tests/memory-diag.test.ts` — 39 tests passing
+- `npm run typecheck` — `TYPECHECK_PASS`
+- `npm test` — 486 tests passing, `TEST_PASS`

+### Evidence Log Schema
+
+Workspace diagnostics also read the append-only evidence log for the current workspace. New evidence records are additive and keep historical records valid:
+
+```typescript
+{
+  version: 1,
+  eventId: string,
+  createdAt: string,
+  workspaceKey: string,
+  workspaceRootHash: string,
+  producerName?: string,
+  producerVersion?: string,
+  instrumentationVersion?: number,
+  type: EvidenceEventType,
+  phase: EvidencePhase,
+  outcome: EvidenceOutcome,
+  reasonCodes: string[],
+  details?: Record<string, string | number | boolean | null | string[] | number[]>
+}
+```
+
+Instrumentation version 2 adds optional causal details for future diagnostics without backfilling old JSONL records. Reinforcement-block events may include `details.blockReason` (for example `same_session` or `same_utc_day`). Capacity-removal events may include `details.strengthAtRemoval`, `details.rankAtRemoval`, `details.typeRankAtRemoval`, and `details.ageDaysAtRemoval`. `memory-diag quality` treats missing producer/instrumentation fields as historical or ambiguous rather than proof of current behavior.

+## Diagnostic Answerability Contract
+
+Every diagnostic section must document:
+
+1. **Question:** What does the reviewer want to know?
+2. **Decision:** What action could the answer inform?
+3. **Competing explanations:** At least two interpretations of the same metric.
+4. **Required signals:** What fields/events distinguish those explanations?
+5. **Current signals:** What currently exists?
+6. **Answerability level:** `supported` | `partial` | `inventory_only` | `not_instrumented`
+7. **Output permission:** What the tool may say without overclaiming.
+
+For `memory-diag quality`:
+- `reinforcementRules`: `inventory_only` (cannot distinguish spam from legitimate blocks)
+- `evictionAndCaps`: `inventory_only` (cannot distinguish healthy turnover from premature eviction)
+- Old evidence remains ambiguous. Answerability improves only for events produced after instrumentation version 2. Mixed old/new logs will show a mix of `inventory_only` and `partial` sections.
+- Producer-instrumented reinforcement blocks can upgrade `reinforcementRules` to `partial` by showing exact block reasons and UTC-day grouping; they still require human content judgment.
+- Producer-instrumented capacity removals with rank/strength snapshots can upgrade `evictionAndCaps` to `partial`; fullness alone remains occupancy inventory, not proof of a capacity problem.

+Use `memory-diag quality` for a read-only, answerability-scoped evidence inventory without automatic cleanup.

+- Primarily provides memory-system mechanism observations for human/agent interpretation.
+- Secondarily helps review active memory content quality.
+- Prints answerability labels and output permissions so inventory facts are not presented as conclusions.
+- Separates system-mechanism facts, memory-content facts, heuristic flags, and review questions.
+- Includes inferred evidence provenance because historical records do not record producer package version.
+- Labels uncertain provenance as `unversioned_ambiguous` so old artifacts are not treated as current mechanism failures.
+- Does not decide what to delete or mutate.
