+## [1.6.5] - 2026-05-19
+
+### Added
+
+- Added `check:package-integrity` to verify `package.json` and on-disk `package-lock.json` root versions stay aligned even though the lockfile remains ignored by git.
+- Added `tsconfig.unused.json` as a strict unused-symbol audit gate for development and release checks.
+- Added package-integrity tests covering matching versions, mismatch reporting, and missing-lockfile guidance.
+- Added storage/evidence contract tests for full-state JSON overwrites and concurrent evidence JSONL appends.
+- Added workspace-memory render-order characterization and memory-visibility order coverage for the shared memory type order.
+
+### Changed
+
+- Centralized the current memory type ordering (`feedback`, `project`, `decision`, `reference`) in a narrow `memory-kind-policy` seam used by workspace rendering, TUI grouping, and memory visibility.
+- Extracted diagnostics producer-version grouping and inference helpers from `memory-diag quality` into a pure diagnostics-only module while preserving the existing JSON and human output contracts.
+- Documented storage write-path contracts in code: `updateJSON` is the locked read-modify-write path, `atomicWriteJSON` is the full-state overwrite primitive, and evidence logs remain append-only JSONL with bounded pruning.
+- Marked legacy parser fixtures and retention caps as intentional compatibility/policy-contract test coverage.
+- Updated developer docs to reference `evaluateWorkspaceMemoryCandidate` instead of the removed private acceptance wrapper.
+
+### Deprecated
+
+- Marked `REINFORCEMENT_MIN_INTERVAL_MS` with JSDoc `@deprecated`; the rolling reinforcement policy uses `REINFORCEMENT_MIN_ELAPSED_MS`.
+
+### Removed
+
+- Removed unused imports and private unused helpers discovered by the new unused-symbol audit, including the private `shouldAcceptWorkspaceMemoryCandidate` wrapper.
+
+### Fixed
+
+- Fixed release hygiene drift detection for the ignored lockfile by adding an explicit package integrity check.
+- Reduced future diagnostics and memory-kind change risk by extracting small behavior-preserving seams without changing runtime memory behavior.
+
+## [1.6.4] - 2026-05-15
+
+### Changed
+
+- Replaced same-session reinforcement blocking with a rolling 7-day elapsed reinforcement window so long-lived OpenCode sessions can reinforce durable memories after meaningful weekly recurrence.
+- Kept the 45-day base half-life while changing the max reinforcement count to a growth saturation point: memories at count 6 can refresh retention timestamps weekly without increasing count or effective half-life.
+- Bumped memory evidence instrumentation to version 3 for the new elapsed-window and refresh-only reinforcement semantics.
+- Updated `memory-diag commands --memory` to show elapsed-window details, `sameSession` evidence, `reinforcementMode`, and legacy missing timestamp markers without exposing raw session IDs.
+- Updated `memory-diag quality` to keep historical `same_session` block accounting while preventing new `sameSession` evidence from triggering old same-session diagnostic questions.
+
+### Fixed
+
+- Prevented long-lived sessions from indefinitely blocking reinforcement solely because the session ID stayed the same across days.
+- Prevented saturated memories from growing stronger beyond the max reinforcement count while still allowing continued weekly use to keep them fresh.
+- Preserved historical block reason compatibility for `same_session`, `same_utc_day`, `min_interval`, and `max_count` without producing those reasons from the new policy path.
+
+## [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.
+
+## [1.6.2] - 2026-05-11
+
+### Fixed
+
+- Fixed the published `memory-diag` npm bin by compiling the diagnostics CLI before packing and launching the compiled JavaScript runtime instead of type-stripping TypeScript under `node_modules`.
+
+### Added
+
+- Added a pack/npx smoke test that runs `memory-diag --help` from a packed tarball outside the repository.
+
+## [1.6.1] - 2026-05-08
+
+### Added
+
+- Native OpenCode TUI `/memory` submenu for local memory statistics, searchable current workspace memory refs, and help.
+- Package `./tui` export for OpenCode TUI plugin loading.
+
+### Changed
+
+- README documents separate server and TUI plugin configuration.
+- Recent activity/last TUI commands were removed before release because duplicate-looking slash menu entries were not useful.
+- Pre-release hyphenated TUI commands were consolidated into `/memory` because native submenu/list dialogs provide better bounded navigation with less slash-menu clutter.
+
+### Fixed
+
+- Replaced a literal NUL byte in `workspace-memory.ts` regex source with a `\0` escape so source search tools treat the file as text.
+
+### Notes / Known UX
+
+- TUI memory command output opens in transcript-free native TUI dialogs and does not call the LLM.
+
+## [1.6.0] - 2026-05-08
+
+### Added
+
+- Numbered compaction memory references (`[M1]`, `[M2]`, ...) for existing rendered workspace memories.
+- Compaction memory commands: `REINFORCE [M#]` for retention reinforcement and `REPLACE [M#] [type] text` for protected replacement.
+- `CompactionMemoryRef` session-state snapshots with optional compaction IDs for overlap detection.
+- Evidence events for numbered memory command outcomes: `memory_reinforced`, `memory_replaced_numbered_ref`, and `memory_reverted_numbered_ref`.
+- Public `memory-diag commands` report for command counts, outcomes, rejection reasons, protected replacement blocks, malformed commands, and latest command events.
+- Public dry-run-first `memory-diag revert` command for manually reverting successful numbered replacements by replacement memory ID or evidence event ID.
+- Hard quality rejection reasons for unresolved questions, transient bug/debug state, and deployment snapshots.
+- Soft `terse_label` diagnostic for very short label-like candidates.
+- Regression tests for command parsing, REINFORCE, protected REPLACE, revert behavior, compaction ref validation, overlap protection, and fallback behavior when the model omits the compaction snapshot ID.
+
+### Changed
+
+- Compaction prompts now include numbered memory refs and concise memory-operation rules instead of asking the model to reuse existing wording exactly.
+- Compaction no longer duplicates hot session state inside the compaction prompt; hot state remains available in normal prompt context.
+- Duplicate maintenance now prefers explicit REINFORCE or protected REPLACE evidence over silent duplicate restatement.
+- Rendered decision memory cap increased from 10 to 12 while keeping the global rendered cap at 28.
+- Rejected memory command evidence now uses neutral `target` relations instead of lifecycle-mutating `reinforced` or `superseded` relation roles.
+- `memory-diag` public command metadata now includes `commands` and `revert` alongside `status`, `rejected`, `missing`, and `explain`.
+
+### Fixed
+
+- Overlapping same-session compactions can no longer silently apply numbered commands against the wrong snapshot when the snapshot ID is present.
+- Numbered command resolution now rejects stale refs whose memory ID, status, or exact key no longer match the current workspace memory entry.
+- Protected replacements are surfaced as first-class diagnostics instead of being buried in generic rejection counts.
+
+### Recovery note
+
+Successful numbered replacements supersede the original memory and add a replacement. To inspect or recover one, run `memory-diag commands --verbose`, then dry-run `memory-diag revert --memory <replacement-memory-id>` or `memory-diag revert --event <event-id>` before adding `--apply`.
+
+## [1.5.5] - 2026-05-05
+
+### Added
+
+- Section-aware greedy line accumulator for hot session state rendering that fits whole lines instead of truncating mid-line.
+- `accountHotSessionStateRender()` accounting function returning prompt text, omitted items, and char budget for v2 evidence extension.
+- Exported types for render accounting diagnostics: `HotStateSection`, `HotStateOmissionReason`, `HotStateOmittedItem`, `HotSessionStateRenderAccounting`.
+- 9 direct unit tests for hot session state rendering covering empty state, ranking, section caps, char budget, boundary conditions, header suppression, wrapper parity, and newline counting.
+- Two-layer omission model: section caps first (`section_cap`), then char budget (`char_budget`), with clear per-item omission reasons.
+
+### Changed
+
+- Hot session state rendering no longer uses blunt `.slice(0, maxRenderedChars)` prompt truncation.
+- Header-only sections are suppressed: a section is only rendered if at least one entry line fits the char budget.
+- `renderHotSessionState()` is now a delegation wrapper to `accountHotSessionStateRender().prompt`, preserving backward compatibility.
+- Fixed `docs/configuration.md` active-file ranking formula: was `count * action_weight * recency_decay` with weights 4/3/2/1, now correctly `ACTION_WEIGHT[action] + count * 3` with weights edit 50, write 45, grep 30, read 20, tie-break by `lastSeen` descending.
+- Clarified `README.md` system prompt injection order: workspace memory and hot state index positions depend on whether workspace memory state is available.
+
+### Fixed
+
+- Hot session state prompt could be truncated mid-line under the old `.slice()` budget enforcement.
+
+## [1.5.4] - 2026-05-02
+
+### Changed
+
+- Centralized the supported `memory-diag` command metadata for the official public commands: `status`, `rejected`, `missing`, and `explain`.
+- Removed pre-public legacy aliases so unsupported spellings now use the standard unknown-subcommand path instead of carrying v2.0 compatibility debt.
+- Kept `coverage` and `audit` as hidden maintainer diagnostics with neutral maintainer-only notices.
+- Removed public npm script exposure for the internal workspace cleanup tool while keeping the development tool in the repository.
+
+### Fixed
+
+- Moved missing-memory disappearance detail formatting into the official `missing` formatter before deleting legacy disappearance formatter code.
+
+## [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.
+
+## [1.5.1] - 2026-04-30
+
+### Added
+
+- Per-workspace evidence log for extraction, promotion, reinforcement, render, storage, and hook lifecycle events.
+- `memory-diag health --json` for machine-readable diagnostics.
+- `memory-diag explain` for per-memory render status, strength, reasons, and evidence event IDs.
+- `memory-diag trace --memory <id>` for memory lifecycle history.
+- UTC calendar-day reinforcement gate so repeated matches cannot inflate a memory multiple times in the same day.
+
+### Changed
+
+- Retention constants and calculations moved to `src/retention.ts`.
+- `safetyCritical` is now fully inert: no retention multiplier and no type-cap bypass, while remaining JSON-compatible.
+
 ## [1.5.0] - 2026-04-29

 ### Added

 - Strength-based workspace memory retention using exponential decay instead of additive priority scoring.
 - Per-type rendered caps for workspace memory candidates: feedback 10, decision 10, project 8, and reference 6.
- Safety-critical memory weighting and type-cap exemption so important entries survive type floods while still competing under the global rendered cap.
 - Dormant-workspace effective age: after 14 days without activity, additional dormant time counts at 0.25x for retention decay.
 - Reinforcement tracking for repeated memories, with same-session and one-hour guards to prevent accidental reinforcement spam.

- **Explicit memory triggers** — users can say “remember this”, “記住”, “覚えて”, or “기억해” to save durable facts.
- **Compaction-based extraction** — memory extraction piggybacks on OpenCode’s existing compaction flow.
- **No manual tools** — memory is injected automatically into the system prompt.
- **Quality guards** — filters noisy memories, temporary progress snapshots, stack traces, raw errors, and credentials.
- **Retention decay** — keeps the strongest memories in prompt context while older or weaker memories fade out naturally; important and reinforced memories decay more slowly.

 ## Installation

-Add OpenCode Working Memory to your OpenCode config:
+New users: add OpenCode Working Memory to both OpenCode plugin configs.
+
+`.opencode/opencode.json`:

 ```json
 {
+  "$schema": "https://opencode.ai/config.json",
  "plugin": ["opencode-working-memory"]
 }
 ```

-Then restart OpenCode. It activates automatically.
+`.opencode/tui.json`:
+
+```json
+{
+  "$schema": "https://opencode.ai/tui.json",
+  "plugin": ["opencode-working-memory"]
+}
+```
+
+Existing users: keep your current `.opencode/opencode.json` config and add only the `.opencode/tui.json` block above to enable the native `/memory` TUI menu.
+
+Then restart OpenCode. Memory activates automatically, and `/memory` appears in the TUI slash command menu.
+
+## Native TUI Memory Menu
+
+The TUI plugin adds one display-only local memory command:
+
+- `/memory` — open a native memory submenu.
+
+Submenu entries:
+
+- Status — show status counts for workspace memory, rendered memories, pending memory, open errors, and recent decisions.
+- Current memories — browse a searchable grouped list of current active workspace memories with display-local `[M1]` refs.
+- Help — show command help.
+
+This menu is read-only and local-only. It reads local memory files and opens native TUI dialogs, so it does not create conversation history entries and does not make an LLM/API call.
+
+```text
+  /memory
+     ├─ Status
+     ├─ Current memories  ← searchable, grouped [M#] refs
+     └─ Help
+```
+
+Use `/memory` when you want to inspect what the agent currently remembers without asking the model or polluting the transcript.
+
+Compaction output already appears through OpenCode's built-in conversation flow. This plugin does not add duplicate compaction notices.

 ## Quality Guards

-OpenCode Working Memory tries to keep memory useful and low-noise.
+**Good memory is selective memory.**

-It includes guards for:
+OpenCode Working Memory is designed to be selective. Its strength is not storing more; it is keeping the prompt focused on durable facts that still help.

- Credential redaction
- Duplicate memory cleanup
- Accounting for promoted, absorbed, superseded, and rejected memories
- Strength-based retention so useful memories stay visible without hard age pruning
- Filtering stack traces, git hashes, raw errors, and noisy path-heavy facts
- Rejecting temporary project progress snapshots
+It protects memory quality in three ways:
+
+- **Selective** — filters temporary progress, raw errors, stack traces, git hashes, noisy debug fragments, and duplicate restatements.
+- **Safe** — redacts credentials and protects manual or explicit memories from unsafe automatic replacement.
+- **Diagnosable** — tracks promoted, absorbed, superseded, rejected, reinforced, and replaced memory outcomes.

 The goal is to remember durable facts, not every detail.

-**Good memory is selective memory.**
-
 Historical cleanup is intentionally conservative: extraction-time filtering may reject more aggressively, but one-time migration cleanup only supersedes high-confidence garbage patterns. This protects existing durable memories written in declarative style, such as "API endpoint is X" or "Product branding is Y".

-For local development cleanup, use:
+### Numbered Memory Refs

-```bash
-npm run cleanup:workspaces -- --dry-run
-npm run cleanup:workspaces -- --quarantine
+During compaction, existing workspace memories may be shown as numbered refs such as `[M1]` or `[M2]`. The model can reinforce a still-useful memory or propose a protected replacement instead of copying the same fact again.
+
+```md
+REINFORCE [M1]
+REPLACE [M2] project Updated durable project fact.
 ```

-The cleanup command only quarantines definite temp/test workspace residues by default. It does not delete unknown missing-root workspaces.
+Protected memories and stale refs are rejected rather than mutated. Use `memory-diag commands` for detailed command outcomes and recovery guidance.
+
+### Memory Diagnostics CLI
+
+For deeper troubleshooting, use the read-only `memory-diag` CLI:

+```bash
+npx --package opencode-working-memory memory-diag status
+npx --package opencode-working-memory memory-diag rejected
+npx --package opencode-working-memory memory-diag missing

 # Release Notes

+## 1.6.5 (2026-05-19)
+
+### Code Health and Release Hygiene
+
+This patch release is an internal health release before the next feature wave. It does not change memory extraction, reinforcement policy, TUI behavior, or the `memory-diag` CLI contract. Instead, it makes the codebase easier to audit and safer to modify.
+
+The release adds package-version integrity checks, a clean unused-symbol audit, focused characterization tests, storage/evidence contract coverage, a narrow shared memory-type ordering seam, and a small diagnostics versioning extraction.
+
+### What Changed
+
+- **Package integrity check**: added `npm run check:package-integrity` to verify `package.json` and the on-disk `package-lock.json` root versions match, with a clear `run npm install first` message when the ignored lockfile is missing.
+- **Unused-symbol audit**: added `tsconfig.unused.json` and cleaned the existing unused imports/private helpers so the audit now passes cleanly.
+- **Memory type order seam**: centralized the current order (`feedback`, `project`, `decision`, `reference`) for workspace rendering, memory visibility, and TUI grouping without creating a broader policy registry.
+- **Storage/evidence contracts**: documented write-path semantics and added tests for full-state JSON overwrite behavior and concurrent evidence JSONL appends.
+- **Diagnostics containment**: extracted producer-version grouping and inference helpers from `memory-diag quality` into a pure diagnostics-only module while preserving existing output shape and wording.
+- **Characterization coverage**: added render-order coverage and labeled compatibility/policy-contract tests so future refactors can distinguish intentional legacy behavior from brittle fixtures.
+
+### Upgrade Notes
+
+- No configuration changes are required.
+- Existing workspace memory files and evidence logs remain compatible.
+- The `memory-diag` CLI JSON shape and human output wording are intended to be unchanged.
+- `package-lock.json` remains ignored by git in this repository; run `npm install` before `npm run check:package-integrity` if the lockfile is missing locally.
+- `REINFORCEMENT_MIN_INTERVAL_MS` remains exported for compatibility but is now marked `@deprecated`; use `REINFORCEMENT_MIN_ELAPSED_MS` for the rolling reinforcement policy.
+
+### Validation
+
+- `npm run check:package-integrity` — `PACKAGE_INTEGRITY_PASS version=1.6.5`
+- `node --import ./tests/setup-xdg-data-home.ts --test --experimental-strip-types tests/package-integrity.test.ts` — 3 tests passing
+- `./node_modules/.bin/tsc -p tsconfig.unused.json` — no unused-symbol errors
+- `node --test --experimental-strip-types tests/memory-diag-quality.test.ts tests/memory-diag.test.ts` — 93 tests passing
+- `node --import ./tests/setup-xdg-data-home.ts --test --experimental-strip-types tests/storage.test.ts tests/evidence-log.test.ts` — 22 tests passing
+- `npm run typecheck` — `TYPECHECK_PASS`
+- `npm test` — 504 tests passing, `TEST_PASS`
+- `npm run build` — `BUILD_PASS`

+
+## 1.6.4 (2026-05-15)
+
+### Rolling Weekly Reinforcement
+
+This patch release fixes the reinforcement policy for users who work in long-lived OpenCode sessions. Reinforcement no longer treats `same_session` as a hard block. Instead, each memory uses a rolling 7-day elapsed window, so recurring preferences can be reinforced after meaningful weekly use even when the session stays open.
+
+The base retention half-life remains 45 days. The max reinforcement count remains 6, but it now acts as a growth saturation point rather than a lifetime hard stop.
+
+### What Changed
+
+- **7-day rolling window**: repeated reinforcement is allowed once 7 rolling days have elapsed since the memory's last reinforcement; 7 days minus 1ms still blocks.
+- **Same-session as evidence**: `sameSession` is recorded for diagnostics but no longer blocks reinforcement by itself.
+- **Refresh-only saturation**: memories at reinforcement count 6 can refresh `retentionClock`, `lastReinforcedAt`, and session evidence after the weekly window without increasing count or effective half-life.
+- **Instrumentation v3**: new reinforcement evidence records elapsed-window fields, `sameSession`, `reinforcementMode`, and legacy missing timestamp markers.
+- **Diagnostics updated**: `memory-diag commands --memory` exposes the new fields, while `memory-diag quality` keeps historical `same_session` block analysis separate from new same-session evidence.
+
+### Upgrade Notes
+
+- No configuration changes are required.
+- Existing workspace memory files and evidence logs remain compatible.
+- Historical diagnostics may still show older block reasons such as `same_session`, `same_utc_day`, `min_interval`, or `max_count`; new instrumentation-version-3 events use the rolling elapsed-window semantics.
+- Consumers of `memory-diag commands --memory --json` should use `reinforcementMode` to distinguish count-increment reinforcement from refresh-only saturation.

+
+### 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.

+
+### Published `memory-diag` Bin Fix
+
+This patch release fixes the published npm package path for `memory-diag`. In v1.6.1 the source-tree CLI tests passed, but the installed package could fail under `npx --package opencode-working-memory memory-diag` because Node refuses TypeScript type stripping for files inside `node_modules`.
+
+v1.6.2 compiles the diagnostics CLI during packing and makes the npm bin launch the compiled JavaScript runtime.
+
+### What Changed
+
+- **Compiled diagnostics runtime**: `prepack` now builds `dist/scripts/memory-diag.js` before the package is packed or published.
+- **Safer npm bin wrapper**: `memory-diag` no longer runs published `.ts` files through `--experimental-strip-types`; it launches the compiled JS artifact and reports a clear reinstall/build message if the artifact is missing.
+- **Packaged-bin smoke test**: release verification now includes a pack/npx smoke test from a temp consumer project outside the repository.
+
+### Upgrade Notes
+
+- No config changes are required.
+- Existing OpenCode server and TUI plugin entry points are unchanged.
+- If you hit the v1.6.1 bin failure, upgrade and rerun:

+### Native TUI Memory Menu
+
+This release adds a native OpenCode TUI memory menu so users can inspect local working memory without asking the model and without adding command output to the conversation transcript.
+
+Open `/memory` in the TUI to browse memory status, current workspace memories, and help from native dialogs.
+
+> Memory should stay visible when you need it — and stay out of the transcript when you are only inspecting it.
+
+```text

+     ├─ Status
+     │    local counts and memory health
+     │
+     ├─ Current memories
+     │    searchable grouped [M#] refs
+     │
+     └─ Help
+          local usage notes
+```
+
+### What Changed
+
+- **Single TUI entry point**: `/memory` opens a native submenu instead of exposing multiple memory slash commands.
+- **Searchable current memory list**: `Current memories` uses OpenCode's native select dialog for bounded scrolling, filtering, and grouping.
+- **Transcript-free inspection**: memory status, list, help, empty states, and errors render in native dialogs instead of user-style session messages.
+- **Server and TUI plugin exports**: the package exposes `./server` and `./tui` entry points for OpenCode plugin loading.
+- **User docs refreshed**: README highlights the `/memory` workflow and moves the full diagnostics CLI reference to `docs/diagnostics.md`.
+
+### Upgrade Notes
+
+- Add `.opencode/tui.json` if you want the native `/memory` TUI menu. Existing server-only configuration continues to work.
+- Restart OpenCode after adding the TUI plugin config.
+- The TUI menu is read-only and local-only. It does not call the LLM.
+- Individual memory row selection is intentionally a no-op in this release; use the list for inspection and search.

+
+### Numbered Memory Refs
+
+This release turns compaction from a one-way memory extractor into a memory maintenance loop. The model now sees numbered references for existing workspace memories and can explicitly reinforce a still-useful memory or propose a protected replacement when compaction reveals that old memory is obsolete.
+
+The goal is not to make memory more aggressive. It is to make memory more accountable: old facts should be strengthened when they keep proving useful, replaced only when the target is safe, and diagnosable when the model tries something risky.
+
+> **Good memory is selective memory.**
+> v1.6 lets memory say “this still matters” without copying it again — and lets obsolete compaction memories fade behind a safer replacement trail.
+
+```text
+  compaction summary
+        │
+        ▼
+  Memory candidates:
+    Memory ref snapshot id: <uuid>
+    [M1] decision · reinforced=2 · source=explicit
+    [M2] project  · reinforced=0 · source=compaction
+        │
+        ├─ REINFORCE [M1]
+        │     ↑ slows decay, no text mutation
+        │
+        └─ REPLACE [M2] project Updated durable fact
+              ↑ only allowed for safe compaction targets
+```
+
+### What Changed
+
+- **Numbered memory refs**: compaction prompts now render existing workspace memories as `[M1]`, `[M2]`, ... references so the model can target a known memory instead of restating it as a duplicate candidate.
+- **REINFORCE commands**: `REINFORCE [M#]` increments the target memory's reinforcement count and updates its retention clock without changing its text.
+- **Protected REPLACE commands**: `REPLACE [M#] [type] text` supersedes the old memory and appends a replacement only when the target is safe: active, compaction-sourced, and not already reinforced.
+- **Reinforce + append workflow**: when a memory is mostly right but needs more context, compaction can reinforce the old memory and emit a new candidate for the new durable fact instead of mutating history.
+- **Compaction prompt restructure**: verbose type definitions and the old “reuse existing wording exactly” instruction were replaced with shorter command rules, categorization guidance, and concrete memory-operation examples.
+- **Hot state removed from compaction context**: active files, current errors, and pending session state remain in normal prompt context but are no longer duplicated inside the compaction prompt, saving budget and reducing accidental promotion of transient state.
+- **New hard quality gates**: unresolved questions, transient bug/debug state, and deployment snapshots are rejected as durable memory candidates.
+- **Soft terse-label diagnostic**: very short label-like candidates are reported for tuning without being hard-rejected in v1.6.
+- **Decision cap raised**: rendered decision memories now have a per-type cap of 12 instead of 10, while the global rendered cap remains 28.
+- **Overlap guard for compaction refs**: memory ref snapshots are tagged with a compaction ID when available, so overlapping same-session compactions cannot silently apply commands against the wrong numbered snapshot.
+- **Safer evidence semantics**: rejected memory command events use a neutral `target` relation role instead of lifecycle roles such as `reinforced` or `superseded`.
+
+### Why This Helps
+
+- Useful memories can become stronger through real reuse instead of duplicate extraction.
+- Obsolete compaction-sourced memories can be replaced with an explicit evidence trail rather than left to drift.
+- Manual, explicit, and already-reinforced memories are protected from automatic replacement.
+- Compaction prompt budget is spent on durable memory maintenance, not on duplicated hot session state.
+- Command outcomes are visible enough to tune the feature after release instead of guessing from reinforcement counts alone.
+
+### Diagnostics
+
+Inspect command behavior with:
+
+```bash
+npx --package opencode-working-memory memory-diag commands
+npx --package opencode-working-memory memory-diag commands --verbose
+npx --package opencode-working-memory memory-diag commands --json
+```
+
+The command report includes:
+
+- compactions with command evidence
+- REINFORCE and REPLACE counts
+- reinforced, superseded, rejected, and blocked outcomes
+- invalid or malformed command counts
+- same-type vs cross-type replacements
+- protected REPLACE blocks, split by reinforced target and protected source
+- latest command events in verbose mode
+
+If a numbered replacement needs manual recovery, use the dry-run-first revert command:
+
+```bash
+npx --package opencode-working-memory memory-diag revert --memory <replacement-memory-id>
+npx --package opencode-working-memory memory-diag revert --memory <replacement-memory-id> --apply
+```
+
+You can also target a replacement evidence event directly:
+
+```bash
+npx --package opencode-working-memory memory-diag revert --event <event-id>
+```
+
+### Safety Model
+
+- REINFORCE never edits memory text.
+- REPLACE is rejected for manual or explicit memories.
+- REPLACE is rejected for already reinforced targets.
+- REPLACE is rejected if the numbered ref no longer matches the current memory ID, status, and exact key.
+- If a compaction snapshot ID is present and mismatched, all numbered commands from that summary are rejected with `missing_memory_ref_snapshot`.
+- If the model omits the snapshot ID, v1.6 falls back to exact memory ref validation for compatibility and command effectiveness.
+
+### Upgrade Notes
+
+- No configuration changes required.
+- Existing workspace memory files remain compatible.
+- Existing session state remains compatible; old sessions without compaction ref snapshots fall back safely.
+- Existing evidence logs remain compatible; new command events are appended only after v1.6 runs.
+- `memory-diag` now exposes two additional public commands: `commands` and `revert`.

+
+### Hot State Rendering Health
+
+This release replaces blunt prompt truncation with a section-aware greedy renderer that fits whole lines and suppresses empty sections, plus render accounting types for future diagnostics.
+
+> **Good rendering is selective too.** If a section doesn't fit, omit it — don't cut it in half.
+
+### What Changed
+
+- **Whole-line rendering**: the hot session state prompt no longer truncates mid-line with `.slice(0, maxRenderedChars)`. A greedy line accumulator fits complete lines and stops when the next line would exceed the 700-char budget.
+- **Header-only sections suppressed**: a section heading is only rendered if at least one entry fits alongside it. No more orphaned `active_files:` headers with no content underneath.
+- **Render accounting**: `accountHotSessionStateRender()` now returns `prompt`, `omitted[]`, and `maxRenderedChars` so future v2 diagnostics can surface which items fell out and why.
+- **Two-layer omission model**: section caps (`section_cap`) trim per-type overflow first, then the char budget (`char_budget`) trims anything that doesn't fit. Each omitted item carries its reason and section.
+- **Backward-compatible wrapper**: `renderHotSessionState()` delegates to the accounting function and returns just the prompt string, preserving existing plugin behavior.
+
+### Docs Fixes
+
+- **Active-file ranking formula corrected**: `docs/configuration.md` now matches the actual implementation — `ACTION_WEIGHT[action] + count * 3` with weights edit 50, write 45, grep 30, read 20, tie-break by `lastSeen` descending. The old docs claimed `count * action_weight * recency_decay` with weights 4/3/2/1.
+- **Injection order clarified**: README now explains that workspace memory and hot state system-prompt positions depend on whether workspace memory state is available.
+
+### Not Included Yet
+
+- Evidence events for omitted items are deferred to v2, pending a `memory-diag` consumer to avoid unused storage litter.
+
+### Upgrade Notes
+
+- No configuration changes required.
+- Existing workspace memory files remain compatible.
+- Hot session state rendering behavior is intentionally different (cleaner output, no mid-line cuts), but the same information is presented when it fits within the budget.

+### Memory Diagnostics Surface Cleanup
+
+This cleanup release keeps the newly published `memory-diag` CLI small before legacy spellings become compatibility debt.
+
+### What Changed
+
+- **Official commands only**: the public CLI surface is `status`, `rejected`, `missing`, and `explain`.
+- **Pre-public aliases removed**: old spellings such as `health`, `quality`, `rejections`, `disappearances`, and `trace` are no longer recognized.
+- **Maintainer diagnostics clarified**: hidden `coverage` and `audit` commands remain available as maintainer-only diagnostics and stay out of public usage output.
+- **Cleaner internals**: current command metadata now has one source of truth, and legacy command/formatter wrappers were removed.
+- **Internal cleanup script hidden**: the workspace cleanup helper is no longer exposed as an npm script; the underlying development tool remains in `scripts/dev/`.

+
+> 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`.

+
+> **Evidence before sublimation.** Every memory decision can be traced.
+
+### What Changed
+
+- **Evidence log**: extraction, promotion, reinforcement, render, and storage events are now recorded in a per-workspace `events.jsonl` with 90-day retention and 5000-event cap.
+- **User explainability**: `memory-diag explain` shows per-memory render status with strength, reasons, and evidence. `memory-diag trace --memory <id>` shows the full lifecycle history.
+- **Machine-readable diagnostics**: `memory-diag health --json` outputs structured `MemoryDiagJSON` for scripting.
+- **Calendar-day reinforcement gate**: reinforcement now requires distinct UTC calendar days, preventing repetitive-task gaming that could inflate a memory's strength within a single day.
+- **SafetyCritical deprecation complete**: the `safetyCritical` field no longer affects retention strength or type-cap bypass. All memories fade by the same rules.
+- **Retention module extraction**: retention constants and calculations moved to `src/retention.ts` for cleaner separation.
+
+### Privacy
+
+- Evidence text previews are credential-redacted. Memory content is stored as truncated hashes, never in full.
+- Diagnostics default to redacted output. `--raw` is available for maintainers.

+```typescript
+{

+  eventId: string,
+  createdAt: string,
+  workspaceKey: string,
+  workspaceRootHash: string,

+}
+```
+
+Instrumentation version 2 added optional causal block details for diagnostics without backfilling old JSONL records. Instrumentation version 3 adds elapsed-window reinforcement details such as `details.elapsedMs`, `details.requiredElapsedMs`, `details.sameSession`, `details.reinforcementMode`, and `details.legacyMissingTimestamp`. Historical reinforcement-block events may still include older `details.blockReason` values such as `same_session`, `same_utc_day`, `min_interval`, `max_count`, or may have missing block details. 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.

+# Memory Diagnostics
+
+Use the read-only diagnostics CLI when you want to understand what OpenCode Working Memory is doing for the current workspace.
+
+The npm package is `opencode-working-memory`; the installed bin is `memory-diag`, so package-qualified `npx` avoids resolving a different package named `memory-diag`.
+
+## Commands
+
+| Question | Command |
+|---|---|
+| Is memory healthy? | `npx --package opencode-working-memory memory-diag` or `npx --package opencode-working-memory memory-diag status` |
+| Why was something rejected? | `npx --package opencode-working-memory memory-diag rejected` |
+| Where did my memory go? | `npx --package opencode-working-memory memory-diag missing` |
+| Why is this memory shown or hidden? | `npx --package opencode-working-memory memory-diag explain <memory-id>` |
+| How are numbered memory commands behaving? | `npx --package opencode-working-memory memory-diag commands` |
+| What reinforcement evidence exists for one memory? | `npx --package opencode-working-memory memory-diag commands --memory <memory-id>` |
+| How do I review memory quality without automatic cleanup? | `npx --package opencode-working-memory memory-diag quality` |
+| Revert a numbered replacement? | `npx --package opencode-working-memory memory-diag revert --memory <replacement-memory-id>` |
+
+## Global Options
+
+- `--workspace <path>` — inspect another workspace; defaults to the current directory.
+- `--verbose` — show detailed diagnostics.
+- `--json` — print machine-readable output where supported.
+
+## 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 for producer-instrumented events, including instrumentation version 2 block details and instrumentation version 3 elapsed-window details. 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, when available, rolling elapsed-window fields; 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.
+
+## Examples
+
+```bash
+npx --package opencode-working-memory memory-diag status
+npx --package opencode-working-memory memory-diag rejected --verbose
+npx --package opencode-working-memory memory-diag missing --workspace /path/to/project
+npx --package opencode-working-memory memory-diag status --json
+npx --package opencode-working-memory memory-diag commands --verbose
+npx --package opencode-working-memory memory-diag commands --memory <memory-id>
+npx --package opencode-working-memory memory-diag quality
+npx --package opencode-working-memory memory-diag revert --memory <replacement-memory-id>
+```
+
+## Quality Review Board
+
+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.
+- Use `--json` for agent/objective review.
+
+## Numbered Memory Command Reports
+
+Use `memory-diag commands` to inspect `REINFORCE [M#]` and `REPLACE [M#]` outcomes from compaction.
+
+```bash
+npx --package opencode-working-memory memory-diag commands
+npx --package opencode-working-memory memory-diag commands --verbose
+npx --package opencode-working-memory memory-diag commands --memory <memory-id>
+```
+
+The report includes successful reinforcements, refresh-only reinforcements, successful replacements, malformed commands, stale refs, protected replacement blocks, and latest command events in verbose mode.
+
+Use `commands --memory <memory-id>` when you need a focused, evidence-only reinforcement view for one memory. It reports current memory status separately from recorded reinforcement attempts, block reasons, missing block details, elapsed-window fields (`elapsedMs`, `requiredElapsedMs`), `sameSession` evidence, `reinforcementMode` (`increment` or `refresh_only`), `legacyMissingTimestamp` when true, and historical UTC-day evidence without judging whether the policy is correct.
+
+Current reinforcement policy uses a rolling 7-day elapsed window. Below reinforcement count 6, allowed attempts increment the count and refresh retention timestamps; at count 6 or higher, allowed attempts refresh retention timestamps without increasing the count. Historical evidence can still show older block reasons such as `same_session`, `same_utc_day`, `min_interval`, `max_count`, or missing block details because evidence logs are append-only and are not backfilled.
+
+## Dry-run Recovery
+
+`memory-diag revert` is dry-run by default. Add `--apply` only after reviewing the planned original/replacement status changes.
+
+```bash
+npx --package opencode-working-memory memory-diag revert --memory <replacement-memory-id>
+npx --package opencode-working-memory memory-diag revert --memory <replacement-memory-id> --apply
+```
+
+You can also target a replacement evidence event directly:
+
+```bash
+npx --package opencode-working-memory memory-diag revert --event <event-id>

+# Native TUI Memory Command UX Implementation Plan
+
+> **For agentic workers:** Use `agenthub-writing-plans-skill` to create this plan and `agenthub-executing-plans-skill` to execute it task-by-task. Steps use checkbox (`- [ ]`) syntax. Wave checkpoints are gates.
+
+**Goal:** Replace the current ambiguous native OpenCode TUI memory slash-command surface with three visibly distinct hyphenated commands before commit/push.
+
+**User outcome:** OpenCode users see only `/memory-status`, `/memory-list`, and `/memory-help` in slash autocomplete; status shows memory statistics, list shows current active workspace memories as display-local `[M1]` refs, and duplicate recent-activity commands are no longer user-facing.
+
+**Architecture:** Keep the existing TUI plugin and no-reply session-message injection path. Change only the command registration/routing layer (`src/tui-plugin.ts`) and the local read/format core (`src/memory-visibility.ts`), then update focused tests and docs. Do not add storage, background jobs, LLM calls, command mutation, or a parallel UI surface.
+
+**Tech stack:** TypeScript ESM on Node >=22.6, OpenCode TUI plugin API, local JSON stores, Node built-in test runner with `--experimental-strip-types`.
+
+**Scope mode:** COMPLETE for the approved UX correction; no implementation code is changed by this plan.
+
+---
+
+## Scope Challenge
+
+- Existing leverage: Reuse `src/tui-plugin.ts` command registration and `api.client.session.prompt({ noReply: true })`; reuse `src/memory-visibility.ts` local read snapshots, redaction helper, and `accountWorkspaceMemoryRender()`/`accountWorkspaceMemoryCompactionRefs()` accounting instead of creating a separate diagnostic subsystem.
+- Minimum complete change: Register three unique top-level slash names, add/route a list formatter, remove visible activity/last commands, make status stats-only, and update README/CHANGELOG/tests to match the new public surface.
+- Scope smell check: Expected code/docs/test touch set is 6 files: `src/tui-plugin.ts`, `src/memory-visibility.ts`, `tests/tui-plugin.test.ts`, `tests/memory-visibility.test.ts`, `README.md`, and `CHANGELOG.md`. `RELEASE_NOTES.md`, `docs/installation.md`, and `docs/configuration.md` do not currently mention the TUI memory commands and should stay unchanged unless implementation reveals new command mentions.
+- Lake vs ocean: The lake is display-only status/list/help for existing local data. Ocean-sized extras remain out of scope: `/memory delete`, `/memory edit`, stable memory IDs in the TUI, interactive list selection, evidence activity dashboards, assistant-style output APIs, and upstream OpenCode TUI changes.
+- Out of scope: No activity/last user-facing commands, no `/memory` space-subcommand autocomplete entries, no new aliases unless OpenCode proves they do not create duplicate menu rows, no persistence schema changes, no LLM/API calls, and no server plugin behavior changes.
+
+## Search and Prior Art
+
+- Layer 1 choices:
+  - `src/tui-plugin.ts:113-148` currently registers four commands with the same `slash.name: "memory"`, causing OpenCode to show multiple identical `/memory` rows.
+  - `src/tui-plugin.ts:58-63` maps internal values `memory.activity` and `memory.last` to the same `"activity"` command, confirming duplication.
+  - `src/memory-visibility.ts:12` currently exposes `MemoryVisibilityCommand = "status" | "activity" | "help"`; `formatMemoryHelp()` at lines 273-288 documents `/memory activity` and `/memory last`.
+  - `src/memory-visibility.ts:213-238` already formats status counts but also includes preview lines; the approved UX wants status focused on statistics and delegates memory content to `/memory-list`.
+  - `src/workspace-memory.ts:937-997` already has numbered ref accounting (`accountWorkspaceMemoryCompactionRefs`) that returns rendered entries, omitted entries, and `refs` with `M1`, `M2`, ... display labels. This is the best existing source for list refs because it respects the same selection/cap logic as compaction refs.
+  - `tests/tui-plugin.test.ts:98-153` covers TUI registration, no-reply injection, routing, no-session warning, dialog clearing, and injection failure.
+  - `tests/memory-visibility.test.ts:53-195` covers status/activity/help formatting and read-only redaction behavior.
+  - `README.md:64-76` and `CHANGELOG.md:8-25` document the current `/memory` status/activity/help UX and must be updated before commit/push.
+- Layer 2 choices: None required. Do not add dependencies.
+- Layer 3 choices: A small `MemoryListModel`/`formatMemoryList()` in `src/memory-visibility.ts` is justified because the TUI needs a user-facing grouped list shape that differs from compaction prompt text.
+- Eureka findings: OpenCode's current slash menu does not visibly distinguish trailing subcommand text, so the technically elegant `/memory status` model is worse UX than three hyphenated top-level commands for this release.
+
+## Architecture
+
+### Components and responsibilities
+
+- `src/tui-plugin.ts`: Owns visible TUI command names and active-session/no-reply injection. It should register exactly three commands with `slash.name` values `memory-status`, `memory-list`, and `memory-help`; internal `value` strings may remain dot-form (`memory.status`, `memory.list`, `memory.help`) because they are not displayed to users.
+- `src/memory-visibility.ts`: Owns read-only local models and markdown/plain-text formatting. It should expose command variants `status`, `list`, and `help`; status should report stats only; list should show active rendered workspace memories with display-local `[M#]` refs; help should list only the three public commands. `MemoryVisibilityCommand` is currently consumed by `src/tui-plugin.ts`; verify no other consumers exist before changing/removing exported command variants.
+- `src/workspace-memory.ts`: No planned edit. Reuse `accountWorkspaceMemoryRender()` for stats and `accountWorkspaceMemoryCompactionRefs()` for capped/ref-capable list selection. If imports need updating, import only existing exported functions.
+- `tests/tui-plugin.test.ts`: Assert unique slash names and removal of user-facing activity/last registrations.
+- `tests/memory-visibility.test.ts`: Assert status/list/help output contracts, redaction/truncation, caps, and fallback routing.
+- `README.md` and `CHANGELOG.md`: Align public docs with the new three-command UX. `RELEASE_NOTES.md` has no 1.6.1 TUI command section today; leave it unchanged unless a later release-notes pass adds one.
+
+### Data flow
+
+```text
+User selects /memory-status, /memory-list, or /memory-help in OpenCode TUI
+  -> src/tui-plugin.ts registered command onSelect
+  -> determine active sessionID from api.route/current session route
+  -> commandFromValue(value) returns "status" | "list" | "help"
+  -> src/memory-visibility.ts renderMemoryCommand(root, sessionID, command)
+       status: read workspace/session/pending snapshots + render accounting counts
+       list: read workspace snapshot + accountWorkspaceMemoryCompactionRefs() + safePreview()
+       help: static command help
+  -> api.client.session.prompt({ sessionID, noReply: true, parts: [{ type: "text", text }] })
+  -> OpenCode renders the report as local no-reply session text; no LLM call is made
+```
+
+### Output contracts
+
+#### `/memory-status`
+
+Required shape:
+
+```md
+## Memory status
+
+Workspace:
+- Active memories: <n>
+- Rendered in prompt: <n>
+- Omitted active memories: <n>
+- Superseded memories: <n>
+
+Pending:
+- Pending in this session: <n>
+- Pending journal memories: <n>
+
+Session:
+- Open errors: <n>
+- Recent decisions: <n>
+
+Use /memory-list to view current [M1]-[M28] memory refs.
+
+Local only: no LLM request was made.
+```
+
+Notes:
+- Remove preview lines from status.
+- Keep zero/empty counts visible.
+- Keep the local-only footer.
+
+#### `/memory-list`
+
+Required shape:
+
+```md
+## Current workspace memories
+
+Display refs are local to this output and may change after memory updates.
+
+feedback:
+- [M1] <redacted/truncated text>
+
+project:
+- [M2] <redacted/truncated text>
+
+decision:
+- [M3] <redacted/truncated text>
+
+reference:
+- [M4] <redacted/truncated text>
+
+Shown: <rendered> of <active> active memories.
+Omitted active memories: <omitted-active>.
+
+Local only: no LLM request was made.
+```
+
+Notes:
+- Use refs that are explicitly display-local, not stable IDs.
+- Group by memory type/kind in the existing order: `feedback`, `project`, `decision`, `reference`.
+- Show only active, non-superseded memories selected by the same caps/budget used for rendered memory refs. The default global cap is 28 (`src/types.ts` via `LONG_TERM_LIMITS.maxEntries`).
+- Apply `safePreview()` or equivalent credential redaction/truncation to every displayed memory text. Do not dump raw JSON or full unbounded memory text.
+- Empty state: `No active workspace memories are stored yet.` plus the local-only footer.
+
+#### `/memory-help`
+
+Required shape:
+
+```md
+## Memory help
+
+Commands:
+- /memory-status — show local memory statistics.
+- /memory-list — show current workspace memories as display-local [M1]-[M28] refs.
+- /memory-help — show this help.
+
+These commands are read-only, local-only, and do not call the LLM.
+```
+
+Notes:
+- Do not mention `/memory`, `/memory status`, `/memory activity`, or `/memory last` as available commands.
+- It is acceptable to keep a short note that mutation commands such as delete/edit are not available, but do not expand scope.
+
+### Error flow
+
+- No active session route: preserve existing warning toast behavior and do not write a message.
+- Local read/format error with a session: preserve existing `## Memory error` stream-visible report.
+- `api.client.session.prompt()` failure: preserve existing error toast and no retry.
+- Unknown internal command value: route to help. Do not register unknown/legacy values in the visible command list.
+
+### Security and permissions
+
+- Commands are read-only over local memory/session/pending files and write only the user-invoked no-reply session output.
+- Display memory text only after redaction and truncation.
+- Do not introduce shell execution, network calls, LLM calls, or file writes to memory stores.
+- Do not treat display-local `[M#]` refs as authorization or stable identity; they are only labels in the printed list.
+
+### Performance
+
+- Status remains O(number of workspace/session/pending entries), using existing bounded stores.
+- List should format at most the rendered/ref-selected memories and must respect existing caps/budgets; avoid full evidence lifecycle joins.
+- Removing activity from the visible UX avoids querying/formatting evidence logs during normal command use.
+
+### Production failure scenarios
+
+- OpenCode still displays aliases or duplicate slash names unexpectedly: keep only three primary `slash.name` values and avoid aliases until verified.
+- User expects `/memory` from an unreleased local build: because this is before commit/push, prefer clean UX over compatibility debt; docs should clearly advertise the three hyphenated commands.
+- Very long memories or credentials appear in stored data: list formatter must redacted/truncate via `safePreview()` and tests should assert credential-like fixture text is absent.
+- More than 28 active memories exist: list reports shown vs active and omitted count; it must not imply refs cover hidden memories.
+
+## Backwards Compatibility Stance
+
+- Treat the current `/memory` space-subcommand surface as pre-public/unshipped for this commit because it produces duplicate-looking menu entries in OpenCode.
+- Remove visible registrations for `/memory`, `/memory status`, `/memory activity`, `/memory last`, and `/memory help`.
+- Do not document old spellings.
+- Internal fallback may continue routing unknown values to help, but do not preserve hidden legacy command entries if OpenCode would show them in autocomplete.
+- If a reviewer requests aliases, add only after confirming aliases do not create extra duplicate menu rows; otherwise defer aliases to a later OpenCode API capability discussion.
+
+## File Plan
+
+- Modify: `src/tui-plugin.ts:58-63` — route `memory.status`, `memory.list`, and `memory.help`; remove activity/last mapping from the public path.
+- Modify: `src/tui-plugin.ts:113-148` — register exactly three commands with `slash.name` values `memory-status`, `memory-list`, `memory-help`; remove `Memory activity` and `Memory last` command objects.
+- Modify: `src/memory-visibility.ts:12-40` — change command/model types from status/activity/help to status/list/help; add `MemoryListModel`; remove or unexport activity-only types/functions if no longer used.
+- Modify: `src/memory-visibility.ts:190-238` — keep stats model but format status as grouped statistics with no previews.
+- Modify: `src/memory-visibility.ts:240-271` — replace activity reader/formatter with list reader/formatter or remove activity code and add list code nearby.
+- Modify: `src/memory-visibility.ts:273-288` — update help to list only `/memory-status`, `/memory-list`, `/memory-help`.
+- Modify: `src/memory-visibility.ts:291-302` — route `"list"` to the new list formatter and remove `"activity"` routing.
+- Modify: `tests/tui-plugin.test.ts` — assert three unique visible commands and route status/list/help.
+- Modify: `tests/memory-visibility.test.ts` — replace activity tests with list tests; update status/help assertions.
+- Modify: `README.md:33,51-76` — update feature copy and Native TUI command docs.
+- Modify: `CHANGELOG.md:8-25` — amend unreleased/current 1.6.1 entry from status/activity/help to status/list/help and note hyphenated names.
+- No planned change: `RELEASE_NOTES.md` — no 1.6.1 TUI command mention exists in current evidence.
+- No planned change: `docs/installation.md`, `docs/configuration.md` — current grep found no TUI command mentions.
+
+## Test Strategy
+
+- Framework: Node built-in test runner via `npm test`; TypeScript via `npm run typecheck`.
+- Unit coverage:
+  - `memory-visibility.ts` status counts with active/superseded/rendered/omitted entries, pending memories, pending journal entries, open errors, and recent decisions; assert no preview section remains.
+  - `memory-visibility.ts` list output with active memories grouped by type, display-local `[M#]` labels, shown/active/omitted summary, redacted credential-like text, empty state, and local-only footer.
+  - `memory-visibility.ts` help text lists only three hyphenated commands and omits `/memory activity` and `/memory last`.
+  - `renderMemoryCommand()` routes `status`, `list`, and `help`; unknown values fall back to help.
+- TUI integration-style unit coverage:
+  - Registers exactly three command values.
+  - Slash names are exactly `memory-status`, `memory-list`, `memory-help` and unique.
+  - No registered command value is `memory.activity` or `memory.last`.
+  - Selecting `memory.status`, `memory.list`, and `memory.help` injects no-reply text with the expected heading.
+  - Existing no-session warning, dialog clearing, and prompt-injection failure behavior still passes.
+- Docs verification:
+  - Grep for old public spellings in markdown and source tests after implementation; old spellings should remain only in this plan or intentionally in negative assertions.
+
+## Implementation Tasks
+
+## Wave 1: Failing Tests for the New Public Contract
+
+### Task 1.1: Update TUI command registration/routing tests first
+
+**Purpose:** Prove the slash command menu no longer contains duplicate-looking `/memory` entries.
+
+**Files:**
+- Modify: `tests/tui-plugin.test.ts`
+
+**Behavior:**
+- Given the TUI plugin registers commands, there are exactly three memory commands.
+- Given autocomplete displays slash names, the names are unique hyphenated top-level commands.
+- Given a command is selected, status/list/help route to distinct headings.
+
+- [ ] **Step 1: Write failing tests**
+
+Add or update assertions equivalent to:
+
+```ts
+test("registers three unique hyphenated memory slash commands", async () => {
+  const api = makeMockTuiApi({ route: { name: "session", params: { sessionID: "ses_1" } } });
+  await MemoryTuiPlugin(api as any, undefined, mockMeta);
+
+  const slashNames = api.commands.map(command => command.slash?.name).filter(Boolean);
+  assert.deepEqual(slashNames, ["memory-status", "memory-list", "memory-help"]);
+  assert.equal(new Set(slashNames).size, slashNames.length);
+  assert.deepEqual(api.commands.map(command => command.value), ["memory.status", "memory.list", "memory.help"]);
+  assert.equal(api.commands.some(command => command.value === "memory.activity"), false);
+  assert.equal(api.commands.some(command => command.value === "memory.last"), false);
+});
+```
+
+Update the routing test to select `memory.list` and expect `## Current workspace memories`.
+
+- [ ] **Step 2: Run expected failure**
+
+Run: `node --import ./tests/setup-xdg-data-home.ts --test --experimental-strip-types tests/tui-plugin.test.ts`
+
+Expected: FAIL because current `src/tui-plugin.ts` registers repeated `slash.name: "memory"` and does not register `memory.list`.
+
+### Task 1.2: Update memory visibility formatter tests first
+
+**Purpose:** Lock the approved status/list/help output shape before implementation.
+
+**Files:**
+- Modify: `tests/memory-visibility.test.ts`
+
+**Behavior:**
+- Status is stats-only and points to `/memory-list`.
+- List prints current active memories grouped by type with display-local refs and redaction.
+- Help lists only three hyphenated commands.
+
+- [ ] **Step 1: Write failing tests**
+
+Required assertions:
+
+```ts
+assert.match(output, /^## Memory status/);
+assert.match(output, /Workspace:/);
+assert.match(output, /Pending:/);
+assert.match(output, /Session:/);
+assert.match(output, /Use \/memory-list to view current \[M1\]-\[M28\] memory refs\./);
+assert.equal(output.includes("Recent active memory previews"), false);
+```
+
+Replace activity tests with list tests that create at least one memory for each type and one superseded memory. The redaction fixture must include at least one short credential-like active memory that is guaranteed to render, such as `Remember password: sushi for the fake test.`, so `output.includes("sushi") === false` proves redaction rather than omission by caps/budget. Assert:
+
+```ts
+assert.match(output, /^## Current workspace memories/);
+assert.match(output, /Display refs are local to this output/);
+assert.match(output, /feedback:\n- \[M\d+\]/);
+assert.match(output, /project:\n- \[M\d+\]/);
+assert.match(output, /decision:\n- \[M\d+\]/);
+assert.match(output, /reference:\n- \[M\d+\]/);
+assert.match(output, /Shown: \d+ of \d+ active memories\./);
+assert.equal(output.includes("sushi"), false);
+assert.equal(output.includes("Superseded memory should not be active"), false);
+```
+
+Update help assertions:
+
+```ts
+assert.match(output, /\/memory-status/);
+assert.match(output, /\/memory-list/);
+assert.match(output, /\/memory-help/);
+assert.equal(output.includes("/memory activity"), false);
+assert.equal(output.includes("/memory last"), false);
+```
+
+- [ ] **Step 2: Run expected failure**
+
+Run: `node --import ./tests/setup-xdg-data-home.ts --test --experimental-strip-types tests/memory-visibility.test.ts`
+
+Expected: FAIL because current implementation still exposes activity/last and lacks list output.
+
+### Wave 1 Checkpoint
+
+- [ ] Confirm both focused test files fail for the expected missing behavior, not unrelated setup errors.
+- [ ] Do not proceed if failures indicate fixture/storage regressions unrelated to command UX.
+
+## Wave 2: Implement the Visibility Core
+
+### Task 2.1: Add list model/formatter and simplify status/help
+
+**Purpose:** Make the local rendering core match the approved command set independently of TUI registration.
+
+**Files:**
+- Modify: `src/memory-visibility.ts`
+
+**Implementation instructions:**
+- Change `MemoryVisibilityCommand` to `"status" | "list" | "help"`.
+- Add a `MemoryListModel` that contains:
+  - `activeMemories: number`
+  - `renderedMemories: number`
+  - `omittedActiveMemories: number`
+  - `groups: Record<LongTermMemoryEntry["type"], Array<{ ref: string; text: string }>>` or equivalent typed structure preserving `feedback`, `project`, `decision`, `reference` order.
+- Implement `getMemoryList(root: string)` using `readWorkspaceMemorySnapshot(root)` and `accountWorkspaceMemoryCompactionRefs(store)`.
+  - Count active memories from the raw/snapshot store by `status !== "superseded"`.
+  - Use accounting `refs` plus `rendered` entries to build display-local refs.
+  - Only use the `refs`, `rendered`, and `omitted` fields from `accountWorkspaceMemoryCompactionRefs()` for the list formatter; discard its `evidence` and `prompt` fields and do not call `appendEvidenceEvents()` from `/memory-list`.
+  - Display text must pass through `safePreview(ref.textPreview)`.
+  - `omittedActiveMemories` should count only `accounting.omitted` entries whose memory is not superseded; `accounting.omitted` can include superseded entries from selection accounting and those must not inflate active omissions.
+- Implement `formatMemoryList(model)` with the required output contract.
+- Update `formatMemoryStatus()` to remove preview output and use grouped stat sections.
+- Update `formatMemoryHelp()` to list only `/memory-status`, `/memory-list`, `/memory-help`.
+- Update `renderMemoryCommand()` switch to route `"list"`.
+- Remove `MemoryActivityModel`, `DEFAULT_ACTIVITY_LIMIT`, `MAX_ACTIVITY_LIMIT`, `clampLimit`, `getMemoryActivity()`, `formatMemoryActivity()`, `formatActivityEvent()`, and `summarizeReasons()` if they become unused. Also remove unused `EvidenceEventV1`/`queryEvidenceEvents` imports.
+- Before deleting activity-only exports/helpers, grep `src/` for `MemoryActivityModel`, `getMemoryActivity`, `formatMemoryActivity`, `formatActivityEvent`, and `summarizeReasons()`; remove them only after confirming there are no cross-module consumers outside `memory-visibility.ts`.
+
+- [ ] **Step 1: Implement minimal code**
+
+Do not modify `src/workspace-memory.ts` unless TypeScript proves an export is missing. Current evidence shows `accountWorkspaceMemoryCompactionRefs` is exported.
+
+- [ ] **Step 2: Run focused verification**
+
+Run: `node --import ./tests/setup-xdg-data-home.ts --test --experimental-strip-types tests/memory-visibility.test.ts`
+
+Expected: PASS.
+
+- [ ] **Step 3: Run typecheck for dead imports/types**
+
+Run: `npm run typecheck`
+
+Expected: PASS and output includes `TYPECHECK_PASS`.
+
+### Wave 2 Checkpoint
+
+- [ ] Status output contains no memory preview content.
+- [ ] List output includes display-local `[M#]` refs, grouped by type, with redacted/truncated text.
+- [ ] Activity/last formatter exports are either removed or no longer referenced by user-facing code.
+
+## Wave 3: Implement the TUI Command Surface
+
+### Task 3.1: Register only three hyphenated slash commands
+
+**Purpose:** Fix OpenCode autocomplete by ensuring visible slash names are unique top-level commands.
+
+**Files:**
+- Modify: `src/tui-plugin.ts`
+
+**Implementation instructions:**
+- Update `commandFromValue(value)`:
+  - `memory.status` -> `"status"`
+  - `memory.list` -> `"list"`
+  - `memory.help` -> `"help"`
+  - default -> `"help"`
+- Update `memoryCommands(api)` to return exactly three objects:
+  - title `Memory status`, value `memory.status`, description `Show working memory statistics in the current session.`, category `Memory`, suggested `true`, `slash: { name: "memory-status" }`
+  - title `Memory list`, value `memory.list`, description `Show current workspace memories with display-local refs.`, category `Memory`, `slash: { name: "memory-list" }`
+  - title `Memory help`, value `memory.help`, description `Show working memory help.`, category `Memory`, `slash: { name: "memory-help" }`
+- Remove `Memory activity` and `Memory last` command objects.
+- Do not include `aliases: ["mem"]` in this wave; aliases can be reconsidered only after verifying they do not create duplicate menu entries.
+
+- [ ] **Step 1: Implement minimal code**
+
+Keep existing active-session guard, no-reply injection, dialog clearing, and prompt failure toast logic unchanged.
+
+- [ ] **Step 2: Run focused verification**
+
+Run: `node --import ./tests/setup-xdg-data-home.ts --test --experimental-strip-types tests/tui-plugin.test.ts`
+
+Expected: PASS.
+
+- [ ] **Step 3: Run adjacent focused verification**
+
+Run: `node --import ./tests/setup-xdg-data-home.ts --test --experimental-strip-types tests/tui-plugin.test.ts tests/memory-visibility.test.ts`
+
+Expected: PASS.
+
+### Wave 3 Checkpoint
+
+- [ ] TUI registration tests prove slash names are unique.
+- [ ] No test expects or selects `memory.activity` or `memory.last`.
+- [ ] No implementation path requires OpenCode to render trailing subcommand text.
+
+## Wave 4: Documentation and Release Metadata Alignment
+
+### Task 4.1: Update user-facing docs
+
+**Purpose:** Ensure install/usage docs no longer advertise broken or removed command spellings.
+
+**Files:**
+- Modify: `README.md`
+- Modify: `CHANGELOG.md`
+- Verify/no change unless needed: `RELEASE_NOTES.md`, `docs/installation.md`, `docs/configuration.md`
+
+**Implementation instructions:**
+- In `README.md` feature bullets, replace “status, recent activity, and help” with “status, current memory list, and help”.
+- In the Native TUI Memory Command section, document:
+  - `/memory-status` — status counts/statistics
+  - `/memory-list` — current active workspace memories with display-local `[M1]` refs
+  - `/memory-help` — help
+- Keep the existing local-only/no LLM/no-reply transcript caveat.
+- Remove docs for `/memory`, `/memory status`, `/memory activity`, `/memory last`, and `/memory help` as available user commands.
+- In `CHANGELOG.md` 1.6.1 entry, amend the current TUI command bullet to say hyphenated `/memory-status`, `/memory-list`, `/memory-help`, and note recent activity/last were removed before release because duplicate entries were not useful.
+- `RELEASE_NOTES.md` currently has no 1.6.1 TUI command mention in the evidence read; do not add a release note unless the release process requires a 1.6.1 section.
+
+- [ ] **Step 1: Update markdown docs**
+
+Use exact command names consistently.
+
+- [ ] **Step 2: Run docs/source grep**
+
+Run equivalent local search:
+
+```bash
+rg "/memory activity|/memory last|/memory status|/memory help|slash: \{ name: \"memory\"|memory\.activity|memory\.last" README.md CHANGELOG.md src tests
+```
+
+Expected: no matches except this plan file if searching the whole repo, or negative test assertions that intentionally verify old commands are absent. The space-separated forms in this grep are obsolete spellings; the correct hyphenated commands `/memory-status`, `/memory-list`, and `/memory-help` should remain present.
+
+### Wave 4 Checkpoint
+
+- [ ] Docs advertise only `/memory-status`, `/memory-list`, `/memory-help`.
+- [ ] Changelog matches the pre-release UX correction.
+- [ ] No release docs mention stale activity/last commands.
+
+## Final Verification
+
+- [ ] Run: `npm run typecheck`
+  Expected: PASS and output includes `TYPECHECK_PASS`.
+- [ ] Run: `npm test`
+  Expected: PASS and output includes `TEST_PASS`.
+- [ ] Run: `npm pack --dry-run`
+  Expected: package contains `index.ts`, `src/tui-plugin.ts`, `src/memory-visibility.ts`, README, LICENSE, and no unexpected generated artifacts.
+- [ ] Manual OpenCode TUI smoke before commit/push:
+  - Configure `.opencode/tui.json` to load the local plugin target.
+  - Open slash command menu and confirm exactly three visible memory commands: `/memory-status`, `/memory-list`, `/memory-help`.
+  - Select `/memory-status`; expected no-reply session text headed `## Memory status`, no assistant response, no LLM/provider activity.
+  - Select `/memory-list`; expected no-reply session text headed `## Current workspace memories`, display-local `[M#]` refs, grouped memory types, redacted/truncated text.
+  - Select `/memory-help`; expected help lists only the three hyphenated commands.
+- [ ] Review changed files for placeholders, dead code, unused activity imports, debug logging, stale docs, raw secret output, and accidental storage writes.
+
+## Review Readiness
+
+- [ ] Scope challenge resolved: this is a focused UX correction, not a memory subsystem rewrite.
+- [ ] Architecture and data flow are explicit.
+- [ ] Every changed behavior has a focused test or manual TUI smoke check.
+- [ ] Failure paths and user-visible states are covered.
+- [ ] Commands are exact and runnable.
+- [ ] Backwards compatibility stance is explicit and pre-release-safe.
+- [ ] Plan has no placeholders.
+
+## Risks and Mitigations
+
+- Risk: Hyphenated names are less elegant than `/memory status` subcommands. Mitigation: current OpenCode menu behavior makes hyphenated top-level names the only visible unambiguous option.
+- Risk: Users may interpret `[M#]` as stable memory IDs. Mitigation: list output must explicitly say refs are display-local and may change after memory updates.
+- Risk: Activity formatter code may be left as unused dead code. Mitigation: typecheck plus source grep should catch unused imports/references; remove activity-only exports unless a maintainer-only consumer is introduced later.
+- Risk: List output may leak long or sensitive memory text. Mitigation: use redaction/truncation for each line and add regression assertions that credential-like fixture text is absent.
+- Risk: Docs drift with the just-added 1.6.1 changelog. Mitigation: amend the same 1.6.1 entry before commit/push rather than adding contradictory release notes.

Ralph Chang	e0357c572a	feat(reinforcement): compaction prompt wording reuse, migration evidence, and validation baseline Wave 1 — Compaction prompt improvement: - Add three wording-reuse bullets to buildCompactionPrompt() under CRITICAL MEMORY RULES: do not create rephrased duplicates, reuse existing wording exactly when re-emitting, only emit new memories when the fact is new, materially corrected, or more specific. - This attacks the root cause of zero reinforcement: compaction generating variant text for the same durable fact. Wave 2 — Bug fixes: - Bug #2: Add placeholder comment to superseded_existing branch in decision dedupe (unreachable until v1.5.4 numbered refs). Preserve as const type assertions. - Bug #3: Add memory_migration_superseded evidence event type. Both P0 and quality cleanup migrations now produce evidence events for superseded entries. loadWorkspaceMemory appends migration evidence on first-load migrations only (idempotent via migration IDs). No historical backfill. - Bug #4: Add documentation comment explaining that feedback identity key returns exact key (absorbed_identity currently impossible for feedback). Add test verifying this behavior. Wave 3 — Validation baseline script: - Add scripts/dev/validate-identity-keys.ts: read-only script that scans workspace memory stores, computes exact/identity key collisions, and reports reinforcement statistics. Baseline matches audit: 0 exact collisions, 0 identity collisions, 0 reinforcement events across 123 active memories. Identity extension is gated on measurement: if the prompt change produces measurable reinforcement (reinforcementCount > 0), identity extension may be unnecessary. Decision dedupe stays exact-only (Wave 4 deferred).	2026-05-02 15:03:34 +08:00

Ralph Chang	f25a235b93	fix(retention): add UTC calendar-day diversity gate to reinforceMemory Implement OQ-2 decision: allow at most one reinforcement per memory identity per UTC calendar day. Same-day reinforcement is blocked regardless of session or interval. This prevents repetitive-task gaming where a daily recurring task could reach MAX_COUNT=6 in hours. Guard order: same-session → calendar-day → 1-hour → max-count (existing guards kept as defense-in-depth) 1 hour guard is redundant within same day but preserved for sub-hour edge cases.	2026-04-30 18:38:29 +08:00

Ralph Chang	aa7cc6c60e	refactor(retention): extract retention module from workspace-memory Move retention constants and math to a focused src/retention.ts module: - All half-life, reinforcement, dormancy constants - TYPE_FACTOR, SOURCE_FACTOR, USER_IMPORTANCE_FACTOR - RETENTION_TYPE_MAX (renamed from TYPE_MAX) - calculateInitialStrength, calculateEffectiveHalfLife, calculateRetentionStrength, calculateDormantDays, calculateEffectiveAgeDays, reinforceMemory No behavior changes. retention.ts imports only types from types.ts. Workspace-memory.ts still owns storage, consolidation, and rendering.	2026-04-30 17:28:31 +08:00
Ralph Chang	36f00147ca	feat(deprecation): remove safetyCritical retention multiplier and type-cap bypass - Remove SAFETY_CRITICAL_FACTOR = 6.0 from workspace-memory.ts - Remove safetyFactor from calculateInitialStrength() - all memories now fade according to the same rules - Remove safetyCritical bypass from applyTypeMaxCaps() - safetyCritical entries compete normally under TYPE_MAX caps - Preserve safetyCritical?: boolean in LongTermMemoryEntry type for backward compatibility (no producer sets it to true) - Update memory-diag to show deprecation warning instead of capacity alert - Update tests: add backward-compatibility fixture test, deprecation strength test, normal cap competition test - Update docs/architecture.md, RELEASE_NOTES.md, CHANGELOG.md, docs/configuration.md Phase 1.5 complete: safetyCritical is now a deprecated field with no active behavior. Safety rules belong in user-controlled agent.md files.	2026-04-30 17:23:01 +08:00
Ralph Chang	830d97c6c6	fix(security): harden hooks, quarantine corrupt JSON, test locks, fix promotion dedupe - Wrap hooks with try/catch to prevent OpenCode disruption - Add warnMemoryHook() for safe error logging - Quarantine corrupt JSON files before fallback - Add cross-process lock safety tests - Fix pending promotion same-batch dedupe - Update docs/architecture.md with lock semantics - 242 tests passing	2026-04-30 11:52:01 +08:00
