fix(package): publish JavaScript plugin entry

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

+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [1.6.7] - 2026-05-31
+
+### Fixed
+
+- Fixed published OpenCode plugin loading under Node-based plugin loaders by compiling the runtime plugin entry to JavaScript and pointing package entry exports at `dist/`.
+- Added package smoke coverage for bare, `./server`, and `./tui` imports from an installed tarball so TypeScript entry points cannot regress under `node_modules`.
+
+## [1.6.6] - 2026-05-20
+
+### Changed
+
+- Froze hot session state with the existing prompt-epoch model to reduce pre-history prompt churn for better prefix KV-cache reuse.
+- Switched frozen prompt cache pressure eviction to recency-aware tracking.
+- Updated README and architecture docs for the new frozen hot snapshot behavior.
+
+### Fixed
+
+- Fixed KV prefix-cache instability caused by per-turn hot session prompt changes.
+
+### Thanks
+
+- Thanks to @nilo85 for opening PR #5 and surfacing the local-LLM KV cache hit-rate issue that led to this release.
+
+## [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.
+- 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.
+- Memory health diagnostics for stored vs rendered counts, type caps, global cap overflow, dormancy, retention monitoring, and strength-ranked top/weakest entries.
+- CLI smoke tests and regression fixtures covering retention decay, stale-prune removal, type caps, reinforcement, invalid timestamps, and diagnostics.
+
+### Changed
+
+- Workspace memory rendering now ranks entries by retention strength, not the previous priority/penalty model.
+- Confidence is retained for compatibility but no longer affects retention scoring.
+- Deprecated `safetyCritical` is retained for JSON compatibility but no longer affects retention strength or type-cap behavior.
+- Old or stale-marked memories are no longer hard-pruned; they remain stored and only fall out of rendered context through strength and cap competition.
+- Existing duplicate promotion and dedupe paths now reinforce the surviving memory instead of only absorbing the duplicate.
+- Health output now separates stored active memories from rendered candidates to make cap behavior easier to understand.
+- Default prompt budgets are lower after calibration against observed rendered output: workspace memory is 3600 characters and hot session state is 700 characters.
+
+### Fixed
+
+- Invalid `updatedAt` or `retentionClock` values no longer produce `NaN` retention strength or unstable sorting.
+- Dormant age calculation only discounts the dormant overlap since an entry was created, so new memories do not inherit old workspace dormancy.
+- Type max totals above the global cap are handled correctly: the global rendered limit still wins.
+
+### Not Included Yet
+
+- Delete tombstones and explicit `supersedes` chain enforcement remain deferred follow-up work.
+- Hot/warm/cold tiered storage remains a future v1.6 direction.
+
+## [1.4.0] - 2026-04-28
+
+### Added
+
+- Local migration audit log for the `2026-04-28-quality-cleanup` migration:
+  `~/.local/share/opencode-working-memory/migration-logs/2026-04-28-quality-cleanup.jsonl`.
+- Local extraction rejection log for rejected compaction memory candidates:
+  `~/.local/share/opencode-working-memory/extraction-rejections.jsonl`.
+- Sanitized real-workspace regression fixtures for memory cleanup migration behavior.
+- Safe workspace residue cleanup tooling that dry-runs by default and quarantines definite temp/test workspace stores instead of deleting them.
+
+### Changed
+
+- Unified memory quality rules in a shared quality gate for compaction memory candidates and cleanup checks.
+- Rewritten compaction memory prompt to reduce over-production of low-quality memories.
+- Changed quality cleanup migration to be conservative: it supersedes only high-confidence garbage patterns, including progress snapshots, raw errors, commit/CI snapshots, temporary status notes, active file snapshots, code/API signatures, path-heavy entries, and empty entries.
+- Soft heuristic failures (`bad_feedback`, `bad_decision`) are intentionally excluded from automatic migration cleanup to protect durable declarative memories such as branding rules, API facts, release rules, user workflow preferences, and architecture decisions.
+- Isolated test runs under a temporary `XDG_DATA_HOME` so test workspaces no longer pollute real local workspace memory data.
+
+### Recovery note
+
+The cleanup migration changes matching entries to `status: "superseded"`; it does not delete the entry. If a useful memory is superseded, inspect the migration audit log and restore by changing that entry back to `status: "active"` in the workspace's `workspace-memory.json`. The migration runs once per workspace.
+
+## [1.3.3] - 2026-04-28
+
+### Fixed
+
+- Added atomic cross-process storage writes with stale-lock recovery and heartbeat refresh to prevent concurrent memory-file corruption.
+- Scoped pending-memory promotion by owner/session so global unowned cleanup no longer removes active owned entries.
+- Retained source-aware pending memories until they are actually promoted, absorbed, superseded, or rejected.
+- Persisted load-time security redaction and expanded Bearer-token redaction to reduce secret retention risk.
+- Hardened workspace normalization, cache bounds, rejected-entry retention, and session cleanup behavior.
+
+## [1.3.2] - 2026-04-27
+
+### Fixed
+
+- Compatibility CI now installs dependencies with `npm install` so it works in this no-lockfile repository.
+- Compatibility CI now runs on Node 24, matching the test command's `--experimental-strip-types` requirement.
+
+## [1.3.1] - 2026-04-27
+
+### Added
+
+- Pending journal retention: max 50 entries, 30-day TTL, automatic pruning on save.
+- Plugin capability test to catch missing OpenCode hooks before release.
+- CI workflow for weekly OpenCode plugin API compatibility testing.
+- Indirect prompt-injection filtering for workspace memory candidates.
+- Expanded credential redaction for common API key, token, secret, credential, auth, and private-key labels.
+
+### Fixed
+
+- Pending memory journal entries are now bounded and pruned instead of growing indefinitely.
+- Adversarial memory candidates that try to override system instructions are rejected before storage.
+- Broader credential-like labels are redacted from workspace memory text.
+
+### Changed
+
+- Memory dedupe is now repo-agnostic: project/reference entries use exact canonical text plus generic URL/path identity, while decision/feedback entries no longer use repository-specific topic heuristics.
+- OpenCode plugin compatibility is documented and declared as `>=1.2.0 <2.0.0`.
+- README limitations now concisely document compatibility, secret handling, semantic-memory scope, plugin ordering, and multi-process write boundaries.
+
+### Known Limitations
+
+- Compatibility is tested against OpenCode plugin API `>=1.2.0 <2.0.0`.
+- Credential redaction is best-effort; do not store secrets.
+- This is working memory, not semantic search.
+- Other prompt or compaction plugins may conflict depending on plugin order.
+- Multi-process writes to the same workspace are not fully serialized.
+
+## [1.3.0] - 2026-04-27
+
+### Added
+
+- P0 consolidation accounting for workspace memory promotion.
+- Accounting-aware deduplication (`dedupeLongTermEntriesWithAccounting`).
+- Accounting-aware normalization (`normalizeWorkspaceMemoryWithAccounting`).
+- Promotion classification: promoted, absorbed, superseded, rejected.
+- Remove absorbed/superseded keys from rejected set to avoid duplicate rejection tracking.
+- Memory quality evaluation fixtures covering accepted durable facts and rejected noisy facts.
+- Sharper compaction memory extraction prompt with concrete good/bad memory examples.
+
+### Fixed
+
+- Promotion accounting now clears only pending memories that survive workspace normalization/cap limits.
+- `session.deleted` now uses shared session ID extraction, matching `session.compacted` behavior.
+- Absorbed duplicate pending memories are accounted for instead of retrying forever.
+- Active vs superseded boundary when promoting pending memories (superseded entries no longer block promotion of same-key active memories).
+- Removed unused `rejected_duplicate_lower_quality` type.
+
+### Changed
+
+- Deferred pending journal safety cap implementation (see TODO in `src/pending-journal.ts`).
+- Clarified superseded accounting semantics: P0 emits events only, does not archive newly superseded records.
+- README structure was streamlined around the automatic memory flow and ongoing memory-quality work.
+- Architecture docs now describe `Memory candidates:` as the primary extraction format and XML candidate blocks as legacy.
+- Superpowers implementation plans are no longer tracked in git.
+
+## [1.2.3] - 2026-04-26
+
+### Added
+
+- Frozen workspace memory snapshot in `system[1]` for better OpenCode prompt-cache stability.
+- Ephemeral hot session state and pending memories in later system messages.
+- Durable pending journal so explicit memories survive until promotion.
+
+### Fixed
+
+- Explicit memories no longer mutate the frozen workspace snapshot mid-session.
+- Pending memories are promoted at safe cache-epoch boundaries.
+
+## [1.2.0] - 2026-04-25
+
+### Added
+
+- Memory V2 three-layer architecture.
+- Workspace memory for durable cross-session decisions, preferences, project facts, and references.
+- Hot session state for active files, open errors, and recent context.
+- Hook-based memory extraction during OpenCode compaction.
+
+### Changed
+
+- Removed manual memory tools in favor of automatic prompt injection.
+- Moved storage to `~/.local/share/opencode-working-memory/`.
+
+## [1.1.0] - 2026-04-24
+
+### Changed
+
+- Improved pre-V2 memory documentation and installation flow.
+
+## [1.0.0] - 2026-04-23
+
+### Added
+
+- Initial release with three-layer memory architecture.
+- Initial OpenCode memory integration.
+- Basic memory extraction and prompt injection.

 ## Installation
 
-Add the plugin 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. The plugin 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.

+\* Conceptually, frozen workspace memory is pushed first when it is non-empty, and the frozen hot snapshot is pushed after workspace memory. If workspace memory is empty, the hot snapshot may be the first plugin-added system message. Actual `system[]` indices also depend on OpenCode and other plugins, so `system[1]` / `system[2+]` is a simplified model.
 
-**Cache-friendly layout:** durable workspace memory is rendered as a stable frozen snapshot for the session, while fast-changing hot session state is appended separately. Compaction starts a new cache epoch, refreshing the workspace snapshot after pending memories are promoted.

+
+**Cache-friendly layout:** durable workspace memory and hot session state are rendered as separate frozen prompts that share the same epoch lifecycle. Hot state is an epoch-start snapshot: active files and open errors can change after it is created, and the conversation/tool transcript is the source of truth for newer events. The plugin intentionally does not invalidate the hot snapshot on active-file, open-error, recent-decision, or pending-memory changes because doing so would defeat prefix KV-cache reuse. Explicit pending memories remain durable and promote safely at compaction, but after the current epoch caches exist they do not force a prompt refresh.

 ## Explicit Memory Triggers
 
-You can explicitly ask the agent to remember durable facts.
-
-Examples:
+Most memory is extracted automatically during compaction. When something is especially important, tell the agent directly:
 
 ```md
 Remember this: we prefer Vitest for new frontend tests.
 記住：這個 repo 發 release 前要先跑 npm test。
-覚えておいて: API clients should use the shared retry helper.
-기억해줘: this project uses pnpm, not npm.
 ```
 
-Supported trigger languages include:
+Use explicit triggers for stable preferences, project rules, architecture decisions, or important references. Then inspect active workspace memory with:
 
-| Language | Examples |
-|---|---|
-| English | `remember this`, `save to memory`, `from now on`, `my preference` |
-| Chinese | `記住`, `记住`, `記得`, `请帮我记住` |
-| Japanese | `覚えて`, `覚えておいて`, `メモして` |
-| Korean | `기억해`, `기억해줘`, `메모해줘` |
-
-Negative requests are respected too:
-
-```md
-Don't remember this.
-不要記住這個。
-覚えないで。
-기억하지 마.
+```text
+/memory → Current memories
 ```
 
-Avoid saving:
+Trigger phrases include `remember this`, `save to memory`, `from now on`, `my preference`, `記住`, `記得`, `覚えて`, and `기억해`.
 
-- Secrets, passwords, tokens, or credentials
-- Temporary progress updates
-- Raw command output
-- Short-lived session details

 ## Quality Guards
 
-The plugin 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
-- Superseding older decisions with newer ones
-- 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.
 
+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".
+
+### Numbered Memory Refs
+
+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.
+```
+
+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
+npx --package opencode-working-memory memory-diag explain <memory-id>
+npx --package opencode-working-memory memory-diag quality
+```
+
+See [Diagnostics](docs/diagnostics.md) for the full command reference, numbered memory command reports, and dry-run recovery workflow.

 # Release Notes
 
+## 1.6.6 (2026-05-20)
+
+### KV Cache Stability
+
+This patch release reduces pre-history prompt churn by freezing hot session state with the existing prompt-epoch model, improving prefix KV-cache reuse for local LLMs.
+
+Thanks to @nilo85 for opening PR #5 and surfacing the cache hit-rate issue.
+
+### What Changed
+
+- Hot session state now uses a frozen epoch snapshot instead of changing on every normal turn.
+- Frozen prompt caches use recency-aware cache pressure eviction.
+- The hot-state prompt now labels itself as an epoch snapshot so conversation/tool history remains the source of truth for newer events.
+
+### Upgrade Notes
+
+- No configuration changes are required.
+- Existing workspace memory files, session state files, and evidence logs remain compatible.
+
+### Validation
+
+- `node --import ./tests/setup-xdg-data-home.ts --test --experimental-strip-types tests/session-state.test.ts` — 14 tests passing
+- `node --import ./tests/setup-xdg-data-home.ts --test --experimental-strip-types tests/plugin.test.ts` — 67 tests passing
+- `npm run typecheck` — `TYPECHECK_PASS`
+- `npm test` — 509 tests passing, `TEST_PASS`

+
+## 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 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.
+
+### Validation
+
+- `node --test --experimental-strip-types tests/retention.test.ts` — 10 tests passing
+- `node --test --experimental-strip-types tests/workspace-memory.test.ts tests/plugin.test.ts` — 181 tests passing
+- `node --test --experimental-strip-types tests/memory-diag.test.ts tests/memory-diag-quality.test.ts` — 93 tests passing

+
+## 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
+

+
+## 1.6.2 (2026-05-11)
+
+### 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:
+
+```bash
+npx --package opencode-working-memory@1.6.2 memory-diag --help
+```
+
+### Validation
+
+- `npm run build` — `BUILD_PASS`
+- `node ./scripts/memory-diag-bin.cjs --help`
+- `npm run test:pack:memory-diag` — packed tarball smoke test passed
+- `npm run typecheck` — `TYPECHECK_PASS`
+- `npm test` — 421 tests passing, `TEST_PASS`
+- `npm pack --dry-run` — includes compiled `dist/` diagnostics artifacts
+
+---
+
+## 1.6.1 (2026-05-08)
+
+### 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
+  /memory
+     │
+     ├─ 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.
+
+### Validation
+
+- `npm run typecheck` — `TYPECHECK_PASS`
+- `npm test` — 421 tests passing, `TEST_PASS`
+- `npm pack --dry-run`
+- Real OpenCode TUI smoke test for `/memory` menu, searchable current memories, and transcript-free output.

+## 1.6.0 (2026-05-08)
+
+### 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`.
+

+- `npm run typecheck` — `TYPECHECK_PASS`
+- `npm test` — 405 tests passing, `TEST_PASS`

+
+### 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/`.
+
+### Validation
+
+- `npm run typecheck` — `TYPECHECK_PASS`
+- `npm test` — 347 tests passing, `TEST_PASS`

+## 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`

+
+## 1.5.1 (2026-04-30)
+
+### Evidence Loop and Explainability
+
+This release adds an evidence-based audit trail for memory lifecycle events and user-facing diagnostics for understanding why memories are rendered, promoted, or rejected.
+
+> **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.
+
+### Upgrade Notes
+
+- No configuration changes required.
+- Existing workspace memory files remain compatible.
+- Evidence logs are created automatically; no migration needed.
+
+### Validation
+
+- `npm run typecheck`
+- `npm test` — 271 tests passing

+## 1.5.0 (2026-04-29)
+
+### Retention Decay Model
+
+This release changes workspace memory retention from hard stale pruning and additive priority scoring to a strength-based decay model.
+
+Think of it like a forgetting curve: memories fade over time, but important and reinforced memories decay slower. Weak entries fall out of rendered prompt context by cap competition, not hard deletion.
+
+> **Memory should fade, so the agent can keep learning.**
+> Important memories decay slower, but every memory must leave room for newer project reality and avoid long-term memory pollution.
+
+```text
+  strength
+    │
+ ██ │╲____   reinforced: slower decline
+    │     ╲______
+ ▒▒ │            ╲__ ordinary memory
+    │               ╲
+    ├ ─ ─ ─ ─ ─ ─ ─ ─╲─ dynamic cap competition zone
+ ░░ │                 ╲  easier for new memories to replace
+    │                  ↑ still stored, not deleted
+    └──────────────────────────────→ time / sessions
+```
+
+### What Changed
+
+- **Strength-based retention**: workspace memory now uses exponential decay: initial strength × age decay.
+- **Better initial strength**: type, source, and user importance now determine how strong a memory starts.
+- **No confidence scoring**: confidence remains in stored data for compatibility, but it no longer affects retention ranking.
+- **Type caps**: rendered workspace memory now caps feedback, decisions, project facts, and references separately so one type cannot monopolize all 28 slots.
+- **Deprecation:** `safetyCritical` field no longer affects retention strength or type-cap bypass. All system memories now fade according to the same rules. Safety rules belong in user-controlled `agent.md` files, not in system memory.
+- **Dormant-aware age**: after 14 inactive days, additional dormant workspace time counts at 0.25x so paused projects do not forget too aggressively.
+- **Reinforcement**: repeated matching memories reinforce the survivor and slow future decay, with same-session and one-hour guards to avoid accidental spam.
+- **No hard stale pruning**: old or stale-marked memories are no longer automatically dropped by age; they lose rendered space only through cap competition.
+- **Calibrated prompt budgets**: observed rendered output was typically under ~2000 characters for workspace memory and ~500 characters for hot session state, so defaults were reduced to 3600 and 700 characters to keep overhead lower while retaining buffer.
+- **Clearer health output**: `memory-diag health` now reports stored vs rendered counts, type caps, global cap overflow, dormancy, retention monitoring, and strength-ranked top/weakest entries.
+
+### Why This Helps
+
+- User preferences and explicit memories are less likely to disappear just because inferred project facts are newer.
+- Feedback, decisions, project facts, and references share prompt space more fairly.
+- Returning to an old workspace is less punishing because dormant time decays more slowly.
+- Maintainers can see why memories are rendered or capped instead of guessing from a single active-memory count.
+- Stale entries can fade out of prompt context without destructive cleanup.
+
+### Diagnostics
+
+Maintainers can inspect retention behavior with:
+
+```bash
+bun scripts/memory-diag.ts health
+```
+
+The health output now includes sections like:
+
+```txt
+Stored active memories: 28
+Rendered candidates: 20
+
+By type:
+  feedback  stored=17  rendered=10  typeCap=10
+  decision  stored=11  rendered=10  typeCap=10
+
+Retention caps:
+  type-capped entries: 8
+  global-cap overflow: 0
+
+Dormancy:
+  dormant discount active: no
+
+Retention monitoring:
+  high_importance_ratio: 0.0% (alert > 30%)
+```
+
+### Not Included Yet
+
+- Delete tombstones are not implemented in this release.
+- Explicit `supersedes` chain enforcement is still deferred.
+- Hot/warm/cold tiered storage remains future work.
+
+### Upgrade Notes
+
+- No configuration changes required.
+- Existing workspace memory files remain compatible.
+- Existing entries without a `retentionClock` fall back safely to existing timestamps.
+- The OpenCode config entry stays the same:
+
+```json
+{
+  "plugin": ["opencode-working-memory"]
+}
+```

+## 1.4.0 (2026-04-28)
+
+### Memory Quality Cleanup
+
+This release improves automatic workspace memory quality without risking broad cleanup of useful existing memories.
+
+The quality gate is now shared across compaction extraction and migration checks, the compaction prompt is stricter about what should become durable memory, and the one-time migration is intentionally conservative.
+
+### What Changed
+
+- **Unified quality rules**: memory quality checks now live in one shared module and apply consistently across feedback, decisions, project facts, and references.
+- **Stricter compaction output**: the compaction prompt now tells the model to save fewer memories and prefer durable facts, user preferences, architecture decisions, and hard-to-rediscover references.
+- **Conservative migration cleanup**: the `2026-04-28-quality-cleanup` migration only supersedes high-confidence garbage patterns, not every rejected memory.
+- **Audit logs**: automatic migration cleanup writes local JSONL audit records so superseded entries can be inspected and restored.
+- **Extraction rejection logs**: newly rejected compaction candidates are logged locally to help calibrate future quality rules.
+- **Regression coverage**: migration behavior is tested against sanitized real-workspace patterns to prevent mass false positives from coming back.
+- **Workspace cleanup tooling**: a dev/admin cleanup command can dry-run or quarantine definite temp/test workspace residues without deleting unknown missing-root workspaces.
+- **Test storage isolation**: test runs now use a temporary `XDG_DATA_HOME`, preventing fixture workspaces from polluting real local memory data.
+
+### What Gets Cleaned Up
+
+The migration may supersede existing `source: "compaction"` memories only when they match hard garbage patterns:
+
+- Empty entries
+- Progress snapshots, such as "Wave 1 completed successfully"
+- Test or suite count snapshots, such as "180 tests passed"
+- Raw errors and stack traces
+- Commit or CI snapshots
+- Temporary status notes, such as "Currently running npm test"
+- Active file snapshots
+- Code or API signatures
+- Path-heavy entries that are just rediscoverable file lists
+
+### What Is Protected
+
+The migration does not supersede entries whose only issue is a soft heuristic failure, such as:
+
+- `bad_feedback`
+- `bad_decision`
+
+This protects useful declarative memories like:
+
+- Product branding rules
+- API facts
+- Release rules
+- Architecture decisions
+- User workflow preferences
+
+Explicit and manual memories are also protected.
+
+### Migration Behavior
+
+- Runs once per workspace.
+- Only affects active `source: "compaction"` entries.
+- Marks matching entries as `status: "superseded"` instead of deleting them.
+- Adds `quality_cleanup` and `quality:<reason>` tags to superseded entries.
+- Writes audit logs to:
+  `~/.local/share/opencode-working-memory/migration-logs/2026-04-28-quality-cleanup.jsonl`
+- Writes extraction rejection logs to:
+  `~/.local/share/opencode-working-memory/extraction-rejections.jsonl`
+
+### Recovery
+
+If a useful memory is superseded, inspect the migration audit log and restore the entry by changing its status back to `"active"` in the workspace's `workspace-memory.json`.
+
+### Workspace Residue Cleanup
+
+If old test/temp workspace stores already exist locally, inspect them first:
+
+```bash
+npm run cleanup:workspaces -- --dry-run
+```
+
+To move definite temp/test residues into a local quarantine folder instead of deleting them:
+
+```bash
+npm run cleanup:workspaces -- --quarantine
+```
+
+The cleanup command skips existing workspace roots and unknown missing-root workspaces by default.
+
+### Upgrade Notes
+
+- No configuration changes required.
+- Existing workspace memory files remain compatible.
+- The OpenCode config entry stays the same:
+
+```json
+{
+  "plugin": ["opencode-working-memory"]

+
+### CI Compatibility Patch
+
+- Fixed the compatibility workflow so dependency installation works without a committed lockfile.
+- Moved compatibility CI to Node 24 so TypeScript-stripping tests run correctly.
+- No runtime or storage changes.
+
+---
+
+## 1.3.1 (2026-04-27)
+
+### Security and Reliability Patch
+
+This patch release keeps the v1.3 memory-consolidation model intact while tightening storage safety, compatibility checks, and repository-agnostic dedupe behavior.
+
+### What Changed
+
+- **Bounded pending journal**: pending memories are capped at 50 entries and pruned after 30 days.
+- **Security hardening**: workspace memory candidates now reject indirect prompt-injection attempts, and redaction covers broader token, secret, credential, auth, and private-key labels.
+- **Compatibility coverage**: plugin capability tests and weekly OpenCode plugin API compatibility CI help catch hook drift before release.
+- **Repo-agnostic dedupe**: long-term memory dedupe no longer depends on hardcoded project-specific topic rules; project/reference memories use generic URL/path identity plus exact canonical matching.
+- **Clearer limitations**: README and changelog now document compatibility, best-effort secret redaction, working-memory scope, plugin ordering, and multi-process write boundaries.
+
+### Thanks
+
+- Thanks @StevenChoo for the security hardening contribution in #3.
+
+### Upgrade Notes
+
+- No user migration is required.
+- Existing workspace memory and pending journal files remain compatible.
+- The OpenCode config entry stays the same:

+  "plugin": ["opencode-working-memory"]

+
+## 1.3.0 (2026-04-27)
+
+### Better Memory Consolidation
+
+This release makes OpenCode Working Memory smarter about what happens to saved memories after compaction. Instead of treating every pending memory as simply "kept" or "not kept", it now understands four outcomes:
+
+- **Promoted** — a new memory was saved to workspace memory.
+- **Absorbed** — the memory was a duplicate of something already remembered.
+- **Superseded** — a newer same-topic decision or preference replaced an older one.
+- **Rejected** — the memory was stale, noisy, or over the workspace memory limit.
+
+### What This Improves
+
+- **Fewer repeated pending memories**: duplicate or superseded memories no longer keep coming back for promotion.
+- **Cleaner long-term memory**: old same-topic decisions are replaced more predictably.
+- **Safer promotion accounting**: pending memories are only cleared when the final normalized workspace memory confirms what happened to them.
+- **More useful compaction output**: the compaction prompt now includes clearer examples of what should and should not become durable memory.
+
+### Also Included
+
+- Memory quality regression fixtures: 5 examples that should be kept and 7 noisy examples that should be rejected.
+- Fix for `session.deleted` session ID extraction so cleanup and promotion use the same event parsing path.
+- Fix for active-vs-superseded promotion behavior: archived superseded entries no longer block a fresh active memory.
+- README and architecture documentation updates.
+
+### Upgrade Notes
+
+- No user migration is required.
+- Existing workspace memory files remain compatible.
+- The OpenCode config entry stays the same:
+
+```json
+{
+  "plugin": ["opencode-working-memory"]
+}
+```
+
+### Tests
+
+- **135 tests 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,

+}
+```
+
+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.

 - Git commit hashes (e.g., `abc1234`)
 - Raw errors (e.g., `Error: something failed`)
 - Stack traces
 - Path-heavy facts (>50% paths)
 - Very short text (<20 chars)
 
-### Deduplication
+### Consolidation, Deduplication, and Retention
 
-Memories are deduplicated using **canonical text matching**:
-1. Normalize: lowercase, strip punctuation, collapse whitespace
-2. Hash the canonical text
-3. Keep the entry with highest confidence
+Memories are deduplicated and consolidated with accounting:
+
+1. Normalize exact text: lowercase, strip punctuation, collapse whitespace.
+2. Group project/reference entries by identity where possible.
+3. Keep decision and feedback entries on exact canonical matching to avoid broad semantic merges.
+4. Keep the best surviving entry by source, confidence, specificity, and freshness tie-breakers.
+5. Emit accounting events so pending memories can be classified as promoted, absorbed, superseded, or rejected.
+
+This prevents absorbed or superseded pending memories from retrying forever while still preserving the active surviving memory.
+
+Retention then decides which active memories are rendered into prompt context. It does not hard-delete old memories by age.
+
+```typescript
+strength = initialStrength * 2 ** (-effectiveAgeDays / effectiveHalfLifeDays)
+```
+
+Initial strength is based on memory type, source, and optional user importance. Confidence remains stored for compatibility but is not part of retention scoring.
+
+Rendered candidates are selected in this order:
+
+1. Exclude `status: "superseded"` entries.
+2. Compute current retention strength.
+3. Sort by strength descending.
+4. Apply per-type caps.
+5. Keep the top 28 rendered entries under the workspace memory character budget.
+
+Default type caps:
+
+| Type | Rendered cap |
+|------|--------------|
+| `feedback` | 10 |
+| `decision` | 10 |
+| `project` | 8 |
+| `reference` | 6 |
+
+The type-cap total is 34, intentionally above the global 28-entry cap. These are maximums, not quotas.
+
+Dormant workspaces age more slowly: after 14 inactive days, additional dormant time counts at 0.25x for retention decay. Repeated duplicate memories reinforce the surviving entry only after a rolling 7-day elapsed window. Below reinforcement count 6, an allowed recurrence increments the reinforcement count and refreshes retention timestamps; at count 6 or higher, an allowed recurrence refreshes retention timestamps without increasing the count. Same-session status is recorded as diagnostic evidence, not as a new-policy block reason.
+
+### Safety-Critical Deprecation
+
+The `safetyCritical` field on `LongTermMemoryEntry` is deprecated as of the retention v1.5.1 model update. It no longer affects retention strength or type-cap bypass. The field is preserved in the type definition for backward compatibility with existing workspace memory JSON files, but has no active behavior. Safety rules should be maintained in user-controlled files such as `agent.md` rather than in system memory.
 
 ### System Prompt Injection
 
 Workspace memory is injected at the top of every message:
 
 ```

 ### System Prompt Injection
 
-Hot session state is injected after workspace memory:
+Workspace memory and hot session state are separate cached prompt layers that share a prompt epoch lifecycle:
+
+```text
+system[1]*: frozen workspace memory
+system[2+]*: frozen hot snapshot
+```
+
+The hot state example below is included in a frozen hot snapshot when the epoch is created or refreshed, not rendered again on every normal turn. Active files and open errors are current at epoch boundaries, not on every normal turn; the plugin intentionally does not invalidate the hot snapshot on active-file or open-error changes because doing so would defeat prefix KV-cache reuse. Explicit pending memories persist in session state and the pending journal, then promote safely at compaction; once the current epoch caches exist, new pending memories do not force pre-history prompt refresh. After epoch start, the conversation/tool transcript is the source of truth for newer events.

+## Retention Model Defaults
+
+Workspace memory retention uses strength-based decay. These constants live in `src/workspace-memory.ts`:
+
+```typescript
+const BASE_HALF_LIFE_DAYS = 45;

+```
+
+Initial strength uses type, source, and user importance factors. Confidence is stored for compatibility but is not used for retention scoring.
+
+Rendered type caps prevent one type from filling all workspace memory slots:

+# 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>
+```

+# Plan: Package JS Entry for OpenCode Node Loader
+
+## Goal
+
+Fix GitHub issue #6 by making the published `opencode-working-memory` package loadable through OpenCode's Node-based plugin loader. The package must not expose TypeScript source files as runtime entry points under `node_modules`.
+
+## Background
+
+`opencode-working-memory@1.6.6` currently publishes:
+
+- `main: "index.ts"`
+- `exports["."]: "./index.ts"`
+- `exports["./server"]: "./index.ts"`
+- `exports["./tui"]: "./src/tui-plugin.ts"`
+
+Node can import the local repo `index.ts`, but refuses to strip TypeScript types for files under `node_modules`. This means local path testing passes while npm/opencode package-cache loading fails.
+
+## Proposed Changes
+
+1. Expand the existing dist build config into a full package build.
+   - Update `tsconfig.memory-diag.json` to include `index.ts`, `src/**/*.ts`, `scripts/memory-diag.ts`, and `scripts/memory-diag/**/*.ts`.
+   - Remove the current exclusions for runtime plugin dependencies: `src/plugin.ts`, `src/tui-plugin.ts`, `src/opencode.ts`, `src/session-state.ts`, `src/extractors.ts`, `src/pending-journal.ts`, `src/promotion-accounting.ts`, and `src/memory-visibility.ts`.
+   - Keep `rootDir: "."` and `outDir: "dist"` so `index.ts` emits to `dist/index.js` and `src/tui-plugin.ts` emits to `dist/src/tui-plugin.js`.
+   - Keep `rewriteRelativeImportExtensions: true` so emitted ESM imports point at `.js`.
+
+2. Update `package.json` runtime entry points.
+   - `main` should point to `dist/index.js`.
+   - `exports["."]` and `exports["./server"]` should point to `./dist/index.js`.
+   - `exports["./tui"]` should point to `./dist/src/tui-plugin.js`.
+
+3. Update build scripts.
+   - Keep one clean build path that emits both plugin runtime JS and `memory-diag` JS.
+   - Preserve the existing `memory-diag` binary wrapper behavior.
+   - Rename or alias the script so the unified dist build is not hidden behind a memory-diag-only name.
+
+4. Update packaging tests.
+   - Add a smoke test that builds/packs/installs the tarball into a temporary prefix and imports `opencode-working-memory` from `node_modules`.
+   - Assert the default export id is `working-memory`.
+   - Assert `opencode-working-memory/server` imports and exposes the same default plugin id.
+   - Assert `opencode-working-memory/tui` imports and exposes the TUI plugin id.
+   - Assert package manifest entry points do not point at `.ts`.
+   - Use an isolated npm cache under `/private/tmp` or the test temp root so local `~/.npm` permissions do not affect the smoke test.
+
+5. Update package file allowlist if needed.
+   - Ensure `dist/`, `scripts/memory-diag-bin.cjs`, `README.md`, and `LICENSE` are included.
+   - Keeping TypeScript source files in the tarball is acceptable only if runtime entry points resolve to JS.
+
+## Affected Files
+
+- `package.json`
+- `tsconfig.memory-diag.json` or a new build tsconfig
+- `tests/smoke/memory-diag-packaging.test.ts` or a new smoke test under `tests/smoke/`
+- `CHANGELOG.md`
+- Possibly `package-lock.json` if package metadata changes require npm to refresh it
+
+## Verification
+
+Run:
+
+```bash
+npm run build
+test -f dist/index.js
+test -f dist/src/tui-plugin.js
+node -e "import('./dist/index.js').then(m => console.log(m.default.id))"
+node -e "import('./dist/src/tui-plugin.js').then(m => console.log(m.default.id))"
+rg 'from\s+\".*\\.ts\"|import\s*\\(.*\\.ts' dist
+npm run typecheck
+npm test
+npm run check:package-integrity
+```
+
+Package-path smoke:
+
+```bash
+rm -rf /private/tmp/owm-pack /private/tmp/owm-install /private/tmp/npm-cache
+mkdir -p /private/tmp/owm-pack /private/tmp/owm-install /private/tmp/npm-cache
+npm pack --cache /private/tmp/npm-cache --pack-destination /private/tmp/owm-pack
+npm install --cache /private/tmp/npm-cache --prefix /private/tmp/owm-install /private/tmp/owm-pack/opencode-working-memory-*.tgz
+node -e "import('/private/tmp/owm-install/node_modules/opencode-working-memory').then(m => console.log(m.default.id))"
+node -e "import('/private/tmp/owm-install/node_modules/opencode-working-memory/server').then(m => console.log(m.default.id))"
+node -e "import('/private/tmp/owm-install/node_modules/opencode-working-memory/tui').then(m => console.log(m.default.id))"
+```
+
+Expected output for both import checks:
+
+```text
+working-memory
+```
+
+For the TUI import, expected output is:
+
+```text
+working-memory-tui
+```
+
+Also inspect the installed package manifest and assert `main`, `exports["."]`, `exports["./server"]`, and `exports["./tui"]` all point to `.js` files.
+
+## Release Preparation
+
+After implementation and verification:
+
+1. Inspect `git diff`.
+2. Confirm the working tree contains only this release fix plus the pre-existing unrelated untracked plan.
+3. Add a `CHANGELOG.md` entry for `1.6.7` describing the Node loader/package entry fix.
+4. Run `npm version patch` or otherwise bump `package.json` and `package-lock.json` to `1.6.7` consistently.
+5. If publishing from `main`, prepare the verified package for publish after the final git diff review.
+
+## Risks
+
+- Build config may expose TypeScript type-check errors in files that were previously excluded from `tsconfig.memory-diag.json`.
+- Package smoke tests that call `npm pack` can fail on the developer machine if `~/.npm` has permission problems; tests should use an isolated cache under `/private/tmp`.
+- OpenCode may resolve `./server` or `./tui` differently from bare package import, so both exports should be checked.
+- `npm run check:package-integrity` currently checks package-lock version alignment only; entry-point assertions must live in packaging tests or a new entry-point check.
+- Publishing both `src/` and `dist/` increases tarball size, but runtime correctness depends on the JS entry points rather than removing sources.
+
+## Rollback
+
+Revert the package entry/build changes and publish a corrected package if the JS entry causes a runtime regression. Existing local-path development remains unaffected by reverting because it can still import TypeScript from outside `node_modules`.

+# 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.

-# Memory V2 Redesign Implementation Plan
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Replace the current heavy four-tier memory plugin with a low-token, no-extra-agent-call memory system that provides workspace-scoped long-term memory and session hot state.
-
-**Architecture:** Implement three layers: stable workspace memory, hot session state, and native OpenCode state integration. Workspace memory is frozen per session and refreshed at compaction boundaries; hot session state tracks active files and unresolved blocking errors automatically from tool events; OpenCode todos remain owned by OpenCode and are only read during compaction.
-
-**Tech Stack:** TypeScript, OpenCode Plugin hooks, Node/Bun file APIs, JSON sidecar storage under user data directory, TypeScript typecheck via `npm run typecheck`.
-
----
-
-## Design Summary
-
-### What changes
-
-- Remove default agent-visible memory tools from the normal flow.
-- Remove raw tool-output cache and pressure-monitor intervention from the core path.
-- Add workspace-scoped long-term memory that persists across sessions but does not cross workspaces.
-- Add hot session state that is fully automatic and tiny: active files, open blocking errors, and recent decisions for compaction only.
-- Reuse OpenCode compaction to extract long-term memory candidates with no extra LLM call.
-- Read OpenCode todos during compaction instead of duplicating todo storage.
-
-### What stays out of memory
-
-- Long-term memory does **not** save file lists, stack traces, code signatures, API docs, git history, architecture snapshots, or temporary task progress.
-- Short-term memory does **not** save todos or dependency facts because OpenCode and project files already own those.
-
----
-
-## File Structure
-
-Current project has a single `index.ts`. This plan splits memory behavior into focused modules while keeping `index.ts` as the plugin entrypoint.
-
-### Create
-
-- `src/paths.ts` — computes workspace-scoped storage paths under user data directory.
-- `src/storage.ts` — atomic JSON read/write helpers with safe defaults.
-- `src/types.ts` — canonical schemas and constants for long-term memory and session state.
-- `src/workspace-memory.ts` — load/save/merge/render long-term workspace memory.
-- `src/session-state.ts` — load/save/update/render active files, open errors, recent decisions.
-- `src/extractors.ts` — deterministic extraction from user messages, tool args, bash output, and compaction summaries.
-- `src/opencode.ts` — thin wrappers around OpenCode SDK calls for latest user messages, summaries, and todos.
-- `src/plugin.ts` — hook orchestration.
-- `tests/extractors.test.ts` — unit tests for deterministic extraction.
-- `tests/workspace-memory.test.ts` — unit tests for merge, dedupe, limits, staleness rendering.
-- `tests/session-state.test.ts` — unit tests for active files and error lifecycle.
-
-### Modify
-
-- `index.ts` — replace monolithic implementation with `export { default } from "./src/plugin";`.
-- `package.json` — add a test script using Node’s built-in test runner or Bun test depending available runtime.
-- `README.md` — update feature description from four-tier memory to Memory V2.
-- `docs/architecture.md` — replace stale four-tier docs with three-layer design.
-- `docs/configuration.md` — document limits and optional debug tools.
-- `AGENTS.md` — update development guide, storage paths, and testing commands.

-
-### Task 3: Add extractor tests before implementation
-
-**Files:**
-- Create: `tests/extractors.test.ts`

----
-
-## Verification Strategy
-
-### Automated
-
-- `npm test` validates extractors, long-term merge/render, and hot session lifecycle.
-- `npm run typecheck` validates TypeScript imports and plugin entrypoint.
-
-### Manual OpenCode smoke tests
-
-1. Start a session with the plugin enabled.
-2. Send: `请记住：这个 workspace 的 memory 功能要默认无感`.
-3. Confirm `workspace-memory.json` is written under `~/.local/share/opencode-working-memory/workspaces/<hash>/`.
-4. Read and edit a file.
-5. Confirm session state active files update.
-6. Run a failing typecheck command.
-7. Confirm open error appears in hot state.
-8. Run a passing typecheck command.
-9. Confirm typecheck error clears.
-10. Trigger or simulate compaction.
-11. Confirm compaction context includes memory candidate instruction and parsed candidates merge after compaction.
-
----
-
-## Risk Controls
-
-- **False memory extraction:** explicit regex only matches strong remember/from-now-on phrasing; compaction extraction uses explicit “what not to save” boundaries.
-- **Token overhead:** no background LLM agent; compaction extraction piggybacks existing compaction call; hot state capped at 1200 chars.
-- **Stale memory:** decision/project/reference entries have stale markers during render.
-- **Privacy:** storage lives in user data directory, not repo, and writes with `0600` mode.
-- **Duplicate todo state:** todos are not stored by the plugin; OpenCode remains source of truth.
-- **Error staleness:** errors clear only after successful validation commands and become `maybe_fixed` after related edits.
-
----
-
-## Self-Review
-
-- Spec coverage: plan implements workspace-scoped cross-session memory, bounded long-term memory, compaction-boundary update, fully automatic hot session memory, and no extra LLM calls.
-- Placeholder scan: plan contains no TBD/TODO placeholders; Tasks 8-10 reference exact expected behavior and code boundaries.
-- Type consistency: `LongTermMemoryEntry`, `WorkspaceMemoryStore`, `SessionState`, `ActiveFile`, `OpenError`, and `SessionDecision` are defined once in Task 1 and reused consistently.
-- Wave coherence: each wave ends with tests/typecheck and a committable checkpoint.

-# Memory Deduplication and Staleness Analysis
-
-Date: 2026-04-26
-
-## Executive recommendation
-
-Fix this at storage time first, then tighten ingestion prompts.
-
-Storage is the safety net. Every memory entry, whether from compaction, explicit user instruction, or future manual editing, already flows through `normalizeWorkspaceMemory()` in `src/workspace-memory.ts`. That is the right architectural choke point for deduplication, supersession, and lifecycle pruning.
-
-Prompt changes are still useful, but only as a quality reducer. They cannot be the source of truth because model output will drift, multilingual phrasing will vary, and old stores already contain bad entries.
-
-Do not add embeddings yet. This repo has 22 entries, a limit of 28, and all current failures are simple lexical/category problems. Embeddings would add latency, dependencies, nondeterminism, and storage shape questions for a problem that can be solved with boring code.
-
-## Current data flow
-
-```text
-OpenCode session.compacted event
-        │
-        ▼
-latestCompactionSummary(client, sessionID)
-        │
-        ▼
-parseWorkspaceMemoryCandidates(summary)
-        │       src/extractors.ts
-        │       - validates shape and basic quality
-        │       - assigns type/source/confidence/staleAfterDays
-        ▼
-updateWorkspaceMemory(directory, store => {
-  store.entries.push(...candidates)
-})
-        │
-        ▼
-normalizeWorkspaceMemory(root, store)
-        │       src/workspace-memory.ts
-        │       - exact canonical dedupe only
-        │       - maxEntries trim
-        ▼
-workspace-memory.json
-```
-
-The broken boundary is clear: ingestion appends all candidates, and normalization only dedupes exact normalized text per type.
-
-## Problem 1: near-duplicate accumulation
-
-### Diagnosis
-
-`canonicalMemoryText()` catches only exact matches after NFKC, lowercase, and punctuation/whitespace collapse. It does not catch:
-
-- same fact with extra location detail
-- same path with slightly different label text
-- same decision revised from version 3 to version 4
-- bilingual restatements of the same project fact
-- new fix superseding an older fix for the same issue
-
-This is not one dedupe problem. It is three different classes wearing the same hat.
-
-```text
-Near duplicate classes
-────────────────────────────────────────────
-project/reference  → entity identity problem
-feedback           → topic preference/result problem
-decision           → supersession/history problem
-```
-
-Treating all of these with one fuzzy text threshold will either miss real duplicates or delete useful distinct decisions.
-
-### Ingestion time vs storage time
-
-Use both, with different jobs.
-
-#### Storage time, required
-
-Add deterministic memory normalization in `src/workspace-memory.ts`:
-
-1. exact canonical dedupe, keep existing behavior
-2. type-specific identity keys for obvious entities
-3. simple lexical similarity for same-type candidates
-4. explicit supersession rules for versioned/solution-style decisions
-5. lifecycle pruning before `maxEntries` trim
-
-Why storage first:
-
-- one code path for compaction, explicit, manual, and tests
-- fixes existing stores on next load/save
-- deterministic and unit-testable
-- does not depend on model behavior
-
-#### Ingestion time, useful but secondary
-
-Improve `buildCompactionPrompt()` in `src/plugin.ts` so compaction receives existing memory and is told to emit only new or replacing facts.
-
-The current prompt already passes rendered workspace memory as background context and says "Do not output this context verbatim." That is not strong enough. Add a small rule near `Memory candidates:`:
-
-```text
-Before emitting a memory candidate, compare it to Background context.
-Do not emit a candidate that repeats an existing memory.
-If a new candidate replaces an older one, write only the newer statement.
-Prefer one canonical statement per project fact, reference path, user feedback topic, or implementation decision.
-```
-
-This will reduce noise. It will not eliminate it. Models repeat themselves. Software should expect this.
-
-### Recommended deduplication strategy
-
-Use deterministic, type-aware dedupe. Avoid embeddings. Avoid global fuzzy dedupe as the main rule.
-
-#### 1. Keep exact canonical dedupe
-
-Current logic is good as the first pass.
-
-```ts
-dedup key = `${entry.type}:${canonicalMemoryText(text)}`
-```
-
-Keep source/confidence tie-breaking.
-
-#### 2. Add type-specific identity extraction
-
-For `project` and `reference`, dedupe by identifiable anchors, not prose.
-
-Examples:
-
-- repo/plugin system facts: normalized phrase key like `opencode-agenthub plugin system`
-- file paths: normalized path key, with backticks stripped
-- URLs/domains if they appear later
-
-For the current data:
-
-```text
-reference:path:.opencode-agenthub/current/xdg/opencode/opencode.json
-project:phrase:opencode-agenthub plugin system
-```
-
-When two entries share the same identity key, merge them by keeping the more useful text:
-
-1. explicit source beats manual beats compaction
-2. higher confidence beats lower confidence
-3. more specific text beats vague text, usually longer but cap this to avoid keeping rambles
-4. newer beats older if specificity/source/confidence tie
-
-This directly fixes:
-
-- `OpenCode plugin config location: ...` vs `OpenCode plugin config: ...`
-- Chinese and English variants that both mention `opencode-agenthub plugin system`
-
-#### 3. Add conservative lexical similarity only inside same type
-
-Use token Jaccard or Dice similarity over normalized tokens after stopword removal. No new dependencies.
-
-Suggested thresholds:
-
-```text
-project/reference: >= 0.72 duplicate
-feedback:          >= 0.70 possible duplicate if same topic anchor exists
-decision:          do not use fuzzy deletion by default
-```
-
-This should be a fallback after identity keys, not the primary system.
-
-Risk: fuzzy matching can delete nearby but distinct decisions. Example: "Markdown headers cause purple text" and "Plain text labels avoid special markup" are related but both useful in the history of the bug.
-
-Keep fuzzy matching conservative and type-scoped.
-
-#### 4. Use explicit supersession for decisions
-
-Decision duplication is fundamentally different. Decisions often form a timeline. Some are still valuable context, some are obsolete.
-
-The pair below is supersession, not duplication:
-
-```text
-Parser supports 3 formats: HTML comment, Markdown section, legacy XML
-Parser supports 4 formats: plain text label, Markdown section, legacy section name, legacy XML
-```
-
-The right model is: newer active decision supersedes older active decision on the same topic.
-
-Keep this simple. Do not build a knowledge graph.
-
-Add a small `decisionTopicKey(text)` heuristic:
-
-```text
-parser supports <n> formats       → decision:parser-supported-formats
-solution: use ...                 → decision:purple-italic-output-format, if text contains purple/italic/markup/markdown/xml/html/comment/label
-use output.prompt ... template     → decision:compaction-template-replacement
-opencode plugin load/config facts  → decision:plugin-loading-config
-```
-
-That sounds bespoke, but that is acceptable here. The repo is small, the memory types are product-specific, and the current bad entries are product-specific. Boring beats clever.
-
-When same decision topic appears:
-
-- keep the newest active entry as active
-- optionally mark the older entry `status: "superseded"` if the type supports it, or drop it during normalization if old status values are not preserved
-- do not render superseded entries
-
-If preserving history matters later, add `supersededBy?: string` and `supersededAt?: string` to the type. Not needed for the first fix.
-
-### Type-specific policy
-
-| Type | Nature | Recommended dedupe | Keep history? |
-|---|---|---|---|
-| `project` | stable facts about repo/system | identity key + conservative similarity | no, keep one canonical fact |
-| `reference` | pointer to path/URL/config | path/URL/entity key | no, keep one canonical pointer |
-| `feedback` | user preference or resolved issue | topic key + newer wins for same issue | usually no |
-| `decision` | implementation choice over time | topic supersession, not fuzzy duplicate deletion | sometimes, but render only active latest |
-
-## Problem 2: stale entries never cleaned
-
-### Diagnosis
-
-`staleAfterDays` exists, but only `renderEntry()` uses it to append `[Xd old, verify]`. Nothing removes or demotes stale entries. As a result, the store is monotonic until `maxEntries` forces a priority trim.
-
-That trim is the wrong cleanup mechanism. It sorts by type/source/confidence, not usefulness. A stale high-priority decision can beat a fresh low-priority reference.
-
-### When to prune
-
-Prune during storage normalization, not render.
-
-`normalizeWorkspaceMemory()` is already called by `load/save/updateWorkspaceMemory()`. That gives one central place to enforce lifecycle rules.
-
-```text
-load/update/save
-      │
-      ▼
-normalizeWorkspaceMemory()
-      │
-      ├─ drop inactive/superseded from active set
-      ├─ exact dedupe
-      ├─ identity dedupe
-      ├─ supersession
-      ├─ stale lifecycle pruning
-      └─ maxEntries trim
-```
-
-Do not prune only on render. Render is presentation. If render hides or labels stale entries while the JSON keeps growing, the system still rots.
-
-Do not require explicit cleanup as the only path. It will not run often enough. An explicit cleanup command can be added later for manual inspection, but automatic normalization should handle the common case.
-
-### Should `staleAfterDays` be enforced?
-
-Yes, but not uniformly as immediate deletion for every type.
-
-`staleAfterDays` means "this should be revalidated after this age." It does not always mean "delete at this age."
-
-Use a two-tier lifecycle:
-
-```text
-fresh              age <= staleAfterDays
-stale              staleAfterDays < age <= staleAfterDays + grace
-prunable           age > staleAfterDays + grace
-```
-
-Suggested grace periods:
-
-| Type | Current staleAfterDays | Grace | Auto-prune? | Rationale |
-|---|---:|---:|---|---|
-| `feedback` | none | none | no age-based prune | User preference can remain valid indefinitely. Prune only by supersession/topic replacement. |
-| `decision` | 45 | 15 | yes if compaction/manual and not explicit | Implementation decisions age fast. Supersession should remove most earlier. |
-| `project` | 60 | 30 | yes if compaction/manual and no strong identity/path | Project facts change slower. Keep explicit project facts unless replaced. |
-| `reference` | 90 | 30 | yes if path no longer exists or prunable age exceeded | References are rediscoverable and can become stale. |
-
-For the first implementation, a simpler rule is enough:
-
-```text
-Never age-prune feedback.
-Never age-prune explicit entries automatically.
-Drop compaction/manual entries when age > staleAfterDays + 30 days.
-Drop superseded entries immediately from the active set.
-```
-
-This keeps user-owned memory safe while preventing compaction sludge.
-
-### Explicit vs implicit contradiction detection
-
-Use explicit supersession for known memory shapes. Do not try general contradiction detection.
-
-General contradiction detection without LLM or embeddings is brittle. With an LLM it is nondeterministic and adds another model-quality surface. The current problem does not need that.
-
-Recommended model:
-
-- explicit supersession for same decision topic, same reference path, same project entity, same feedback topic
-- newer entry wins inside the same topic unless older has higher source priority
-- if `source === "explicit"`, require a newer explicit entry to replace it, or keep both
-
-This gives predictable behavior and avoids deleting user instructions because a compaction guessed a replacement.
-
-## Concrete implementation plan
-
-### P0: centralize deterministic cleanup in `src/workspace-memory.ts`
-
-Add helpers near `canonicalMemoryText()`:
-
-```text
-normalizedTokens(text)
-extractPathKeys(text)
-memoryIdentityKeys(entry)
-decisionTopicKey(text)
-feedbackTopicKey(text)
-isPrunableByAge(entry, now)
-chooseBetterMemory(existing, candidate)
-```
-
-Then change `enforceLongTermLimits(entries)` to run in phases:
-
-```text
-1. keep active entries only
-2. truncate text
-3. drop entries prunable by age, except feedback and explicit
-4. exact canonical dedupe
-5. identity-key dedupe for project/reference/feedback
-6. decision-topic supersession
-7. sort by priority with freshness as a tie-breaker
-8. slice to maxEntries
-```
-
-Add freshness to `priority()` or to the final sort tie-breaker. Do not let 90-day-old compaction entries beat fresh entries just because type weight is higher.
-
-Minimal version:
-
-```text
-priority desc, source priority desc, freshness desc, updatedAt desc
-```
-
-### P1: improve compaction prompt
-
-Update `buildCompactionPrompt()` with dedupe instructions before the `Memory candidates:` examples.
-
-Keep this short. Long prompts invite drift.
-
-### P1: add tests before changing behavior
-
-Use `tests/workspace-memory.test.ts` for normalization behavior.
-
-Required regression tests:
-
-```text
-CODE PATH COVERAGE
-==================
-[+] enforceLongTermLimits(entries)
-    ├── [GAP] exact canonical duplicate still dedupes
-    ├── [GAP] project opencode-agenthub bilingual/long-short variants collapse to one
-    ├── [GAP] reference same config path variants collapse to one
-    ├── [GAP] decision parser 4 formats supersedes parser 3 formats
-    ├── [GAP] feedback purple/italic newer fix supersedes older fix
-    ├── [GAP] stale compaction decision older than staleAfterDays + grace is pruned
-    ├── [GAP] stale explicit decision is retained
-    └── [GAP] maxEntries trim runs after dedupe/prune
-
-[+] renderWorkspaceMemory(store)
-    └── [GAP] does not render superseded/pruned entries
-```
-
-No E2E needed. These are pure functions and deterministic store normalization paths.
-
-### P2: optional explicit cleanup command
-
-Later, add a manual cleanup/report command that prints:
-
-- duplicates removed
-- superseded decisions
-- stale entries pruned
-- entries retained because explicit
-
-Not needed for the first fix. Useful for trust once memory stores grow.
-
-## Why not embeddings
-
-Embeddings are the wrong tool at this scale.
-
-Costs:
-
-- new dependency/API or local model decision
-- cache/versioning problem for embedding vectors
-- nondeterministic thresholds
-- hard-to-debug deletions
-- privacy and offline behavior questions
-
-The current store has 22 entries. The failures are obvious strings, paths, topics, and versioned decisions. Use deterministic rules now. Reconsider embeddings only if stores grow into hundreds of entries and lexical/topic rules fail in real usage.
-
-## Risks and tradeoffs
-
-### Risk: deleting useful historical decisions
-
-Mitigation: do not apply broad fuzzy dedupe to `decision`. Use topic-specific supersession only for known patterns. Keep explicit entries unless explicitly replaced.
-
-### Risk: bespoke topic keys become a pile of regexes
-
-Mitigation: keep the first version tiny and test-driven. Add keys only for observed failures. If this grows past roughly 10 topic rules, revisit the model.
-
-### Risk: prompt-only fix gives false confidence
-
-Mitigation: prompt change is P1, storage normalization is P0. The store must protect itself.
-
-### Risk: stale pruning removes something still useful
-
-Mitigation: no age pruning for feedback, no automatic age pruning for explicit entries, and grace periods for compaction/manual entries.
-
-### Risk: normalization mutates existing stores unexpectedly
-
-Mitigation: add tests with fixtures from the current store. Consider logging cleanup counts in development if a logging channel exists. The output should be deterministic.
-
-## NOT in scope
-
-- Embedding similarity, too much machinery for 22 entries.
-- LLM-based contradiction detection, nondeterministic and hard to test.
-- Full memory history graph with `supersededBy`, useful later but not required for current rendering quality.
-- New cleanup UI or CLI, optional P2 after deterministic normalization lands.
-- Changing `LongTermMemoryEntry` schema, avoid migration unless history preservation becomes required.
-
-## Prioritized steps
-
-1. **P0: Add tests in `tests/workspace-memory.test.ts` using the concrete duplicate examples from the current store.** This locks the desired behavior before touching cleanup logic.
-2. **P0: Implement storage-time cleanup in `enforceLongTermLimits()`.** Exact dedupe, identity-key dedupe, decision supersession, stale pruning, then max-entry trim.
-3. **P0: Make stale lifecycle enforceable but conservative.** No age pruning for feedback or explicit entries. Prune compaction/manual entries after `staleAfterDays + 30`.
-4. **P1: Tighten `buildCompactionPrompt()` to avoid re-emitting existing memories and emit only replacing facts.** This reduces future noise but is not trusted as the only defense.
-5. **P1: Add regression fixtures matching the real `workspace-memory.json` problem set.** Assert resulting entries are below the current 22 and contain the newer/canonical facts.
-6. **P2: Add a cleanup report command only if users need visibility.** Defer until after the automatic path proves itself.
-
-## Final architecture decision
-
-The memory store should be self-cleaning at its storage boundary.
-
-Use prompt engineering to reduce bad candidates, but make `src/workspace-memory.ts` the authority for what persists. Use deterministic, type-aware dedupe instead of embeddings. Treat `project` and `reference` as entity identity problems, `feedback` as topic replacement, and `decision` as explicit supersession.
-
-That is the smallest design that solves the real failures without turning a 28-entry JSON file into a search platform.
-
-## Addendum: bracketless memory candidate format from real compaction
-
-Date: 2026-04-26
-
-### Summary table
-
-| Issue | Severity | Fix | Priority |
-|-------|----------|-----|----------|
-| Parser silently drops `- project text` bracketless candidates | High | Accept both `- [type] text` and `- type text` | P0 |
-| Prompt examples imply brackets but do not explicitly require exact syntax | Medium | Add "Use exactly this format, including square brackets" plus a negative example | P0, same small patch |
-| No regression test for bracketless candidate lines | High | Add parser test covering all four types in bracketless form | P0 |
-| Future compactions may re-extract useful facts with changed counts or wording | Medium | Keep storage-time type-aware dedupe/staleness plan | P0, unchanged |
-
-### 1. Parser fix
-
-Accept `- type text` with no brackets.
-
-Also strengthen the prompt. Do both.
-
-The parser is the product boundary. Model output is not a contract, it is an input from an unreliable narrator with excellent vibes. If the model emits a plainly parseable, semantically valid candidate, dropping it silently is a data loss bug.
-
-The prompt should still ask for the preferred bracketed format because bracketed type markers are less ambiguous. But prompt enforcement alone is not enough. The new evidence proves the model sometimes drops brackets even when examples include them.
-
-Recommended parser behavior:
-
-- preferred: `- [project] pathology-playground 後端健康改進計劃已完成 Phase 1-4`
-- accepted fallback: `- project pathology-playground 後端健康改進計劃已完成 Phase 1-4`
-- still reject unknown types
-- still run `shouldAcceptWorkspaceMemoryCandidate()`
-- still require body length and existing quality gates
-
-### 2. Prompt format enforcement
-
-Yes, add explicit syntax instructions.
-
-Current prompt shows examples, but examples are not a hard enough constraint. Add one sentence before the examples:
-
-```text
-Use exactly this candidate format, including square brackets around the type:
-```
-
-Then keep the examples:
-
-```text
-Memory candidates:
-- [feedback] content
-- [project] content
-- [decision] content
-- [reference] content
-```
-
-Optionally add one short warning:
-
-```text
-Do not write `- project content`; write `- [project] content`.
-```
-
-Keep this short. Long formatting lectures increase prompt surface area and make the summary worse. One positive instruction plus one negative example is enough.
-
-### 3. Impact on dedup plan
-
-Parser robustness moves to P0, before storage dedup/staleness cleanup.
-
-This changes sequencing, not the architecture.
-
-Updated P0 order:
-
-1. **P0a: Fix parser format tolerance and add regression tests.** Lost memory is worse than duplicate memory. A deduper cannot dedupe entries that never made it into the store.
-2. **P0b: Implement storage-time dedupe and stale pruning.** Still the main long-term quality fix.
-3. **P0c: Tighten prompt format instruction in the same small patch as parser tolerance.** Cheap and reduces fallback-parser usage.
-
-The earlier recommendation still stands: storage normalization remains the authority for duplicates and staleness. This new evidence adds a more basic ingestion reliability bug in front of it.
-
-### 4. Concrete implementation recommendation
-
-#### Regex change
-
-Replace the current parser line in `src/extractors.ts:parseWorkspaceMemoryCandidates()`:
-
-```ts
-const item = line.trim().match(/^-\s*\[(feedback|project|decision|reference)\]\s*(.+)$/i);
-```
-
-with a single regex that accepts bracketed and bracketless forms:
-
-```ts
-const item = line.trim().match(
-  /^-\s*(?:\[(feedback|project|decision|reference)\]|(feedback|project|decision|reference)\b)\s+(.+)$/i,
-);
-if (!item) continue;
-
-const type = (item[1] ?? item[2]).toLowerCase() as LongTermType;
-const body = item[3].trim();
-```
-
-Why this shape:
-
-- `(?:[type]|type\b)` accepts both formats
-- `\b` prevents `projectile` from being parsed as `project`
-- `\s+(.+)` requires real content after the type
-- unknown types still fail
-
-Even better for readability, avoid duplicate type alternation with a named group if the runtime target supports it cleanly:
-
-```ts
-const item = line.trim().match(
-  /^-\s*(?:\[(?<bracketed>feedback|project|decision|reference)\]|(?<plain>feedback|project|decision|reference)\b)\s+(?<body>.+)$/i,
-);
-if (!item?.groups) continue;
-
-const type = (item.groups.bracketed ?? item.groups.plain).toLowerCase() as LongTermType;
-const body = item.groups.body.trim();
-```
-
-Recommendation: use the non-named-group version. It is uglier, but it is maximally boring and consistent with the existing code style.
-
-Add tests in `tests/extractors.test.ts`:
-
-```ts
-test("parseWorkspaceMemoryCandidates accepts bracketless candidate format", () => {
-  const summary = `
-Memory candidates:
-- project pathology-playground 後端健康改進計劃已完成 Phase 1-4
-- reference Scrypt 參數必須是 N=16384, r=8, p=1
-- feedback 端口 9473 可能被舊進程佔用，需殺掉後重啟
-- decision Use output.prompt to replace the default compaction template
-`;
-
-  const items = parseWorkspaceMemoryCandidates(summary);
-
-  assert.equal(items.length, 4);
-  assert.deepEqual(items.map(item => item.type), [
-    "project",
-    "reference",
-    "feedback",
-    "decision",
-  ]);
-});
-```
-
-Also add a guard test:
-
-```ts
-test("parseWorkspaceMemoryCandidates rejects unknown bracketless candidate type", () => {
-  const summary = `
-Memory candidates:
-- note this should not be parsed as memory
-`;
-
-  const items = parseWorkspaceMemoryCandidates(summary);
-
-  assert.equal(items.length, 0);
-});
-```
-
-#### Prompt change
-
-In `src/plugin.ts:buildCompactionPrompt()`, change this block:
-
-```ts
-"At the end of the summary, extract durable memory entries for future",
-"sessions using these labels:",
-"",
-"Memory candidates:",
-"- [feedback] content",
-"- [project] content",
-"- [decision] content",
-"- [reference] content",
-```
-
-to:
-
-```ts
-"At the end of the summary, extract durable memory entries for future",
-"sessions using exactly this candidate format, including square brackets around the type:",
-"",
-"Memory candidates:",
-"- [feedback] content",
-"- [project] content",
-"- [decision] content",
-"- [reference] content",
-"",
-"Do not write '- project content'; write '- [project] content'.",
-```
-
-This gives the model a crisp positive format and a concrete anti-pattern. The parser still accepts the anti-pattern because users need data capture more than format purity.
-
-### Final addendum decision
-
-Parser tolerance is now P0.
-
-The architecture stays the same: make the storage layer self-cleaning, and make ingestion defensive. But the implementation sequence changes because silent data loss beats duplicate accumulation in severity. First capture valid candidates reliably. Then dedupe and prune them.
-
-## Addendum 2: content quality guidance
-
-Date: 2026-04-26
-
-### Summary table
-
-| Issue | Severity | Fix | Priority |
-|-------|----------|-----|----------|
-| Model extracts low-durability progress snapshots as `project` memory | High | Add durable-content guidance to compaction prompt | P0 |
-| Exact counts like `1237 tests pass` and `37 files` churn across sessions | High | Add parser quality filter for obvious snapshot patterns | P0 |
-| Stable config values are useful and should still pass | Medium | Keep `reference` guidance permissive for config/crypto/PIN values | P0 |
-| Environment issues like occupied ports may be useful briefly but not long-term | Medium | Prompt says unresolved issues only; storage staleness handles aging | P1 with staleness work |
-
-### 1. Architecture fit
-
-This belongs in both the prompt and the parser, with different responsibilities.
-
-The prompt should teach the model what "durable" means. The model is choosing what to extract, so it needs product semantics:
-
-- stable configuration values are good memory
-- unresolved bugs can be useful memory
-- exact test counts, file counts, and phase progress are usually bad long-term memory
-
-The parser should still reject obvious low-durability snapshots as a backstop. The parser already has `shouldAcceptWorkspaceMemoryCandidate()` in `src/extractors.ts`; this is exactly where simple content-quality gates belong.
-
-Do not put subtle semantic judgment in the parser. Do put obvious anti-patterns there.
-
-Recommended split:
-
-```text
-Prompt
-  └─ positive/negative guidance for durable memory selection
-
-Parser quality gate
-  └─ deterministic rejection of obvious snapshots
-     - exact test counts
-     - exact file counts
-     - completed Phase N-M progress lines
-     - temporary port/process cleanup notes when phrased as resolved/current env state
-
-Storage normalization
-  └─ dedupe, supersession, age-based pruning
-```
-
-This is the same design principle as the bracketless parser addendum: ask the model nicely, then make the code defensive.
-
-### 2. Specificity vs risk
-
-The proposed guidance is specific, but not too specific.
-
-It names examples from the observed failure mode, but the rule underneath is general: facts should stay true across sessions. Exact counts and phase numbers are classic snapshot smell in almost every codebase.
-
-Potential risk: sometimes an exact count is genuinely durable. Example: "USB sync protocol expects exactly 37 manifest entries" could be a stable contract, not a snapshot.
-
-Mitigation: word the guidance around "session-specific progress" rather than banning all numbers. Keep config values explicitly allowed.
-
-Good distinction:
-
-```text
-Bad: 1237 tests pass today
-Good: Test suite is expected to pass before handoff
-
-Bad: USB sync currently has 37 files
-Good: USB sync covers bundles, server, frontend, tests, and docs
-
-Bad: Phase 1-4 completed
-Good: Backend health work is organized into phased improvements
-
-Good: Scrypt parameters are N=16384, r=8, p=1
-```
-
-The first three are progress snapshots. The Scrypt value is a stable configuration contract. Numbers are not the problem. Temporary state is the problem.
-
-### 3. Prompt length concern
-
-Adding four lines is worth it.
-
-This prompt is already making the model do extraction. Without guidance, the model optimizes for "important-looking facts," and progress snapshots look important. That creates churn, duplicates, and stale memory. Four lines preventing bad memory at the source are cheap.
-
-If trimming is needed, trim redundant formatting language before removing quality guidance. Formatting mistakes lose entries or require parser tolerance. Content mistakes pollute the store. Both matter, but the durable-content guidance carries more product value than repeated Markdown formatting reminders.
-
-Recommended trim posture:
-
-- keep one concise formatting instruction
-- keep one concise candidate syntax instruction
-- add one concise durable-content block
-- avoid long examples or taxonomy tables in the prompt
-
-The prompt should not become a memory policy document. It just needs the model to stop writing "1237 tests pass" into long-term storage. Wild that we have to say this, but we do.
-
-### 4. Concrete prompt recommendation
-
-In `src/plugin.ts:buildCompactionPrompt()`, replace the candidate instruction block with this final version:
-
-```ts
-"At the end of the summary, extract durable memory entries for future sessions.",
-"Only extract facts that are likely to stay true across sessions.",
-"Do not extract session-specific progress like exact test counts, file counts, or phase numbers.",
-"For progress, extract the stable goal or durable milestone, not the current number.",
-"For references, extract configuration values that do not usually change between sessions.",
-"For feedback, extract unresolved issues or user preferences that future sessions need to know.",
-"Use exactly this candidate format, including square brackets around the type:",
-"",
-"Memory candidates:",
-"- [feedback] content",
-"- [project] content",
-"- [decision] content",
-"- [reference] content",
-"",
-"Do not write '- project content'; write '- [project] content'.",
-```
-
-This is slightly longer than the lead's proposal, but it avoids an overbroad ban on numbers by saying "session-specific progress." It also gives a positive replacement behavior: stable goal or durable milestone.
-
-If a shorter version is required, use this:
-
-```ts
-"At the end of the summary, extract durable memory entries for future sessions.",
-"Only extract facts likely to stay true across sessions; skip exact test counts, file counts, phase numbers, and temporary environment state.",
-"References may include stable configuration values. Feedback should be unresolved issues or user preferences future sessions need.",
-"Use exactly this candidate format, including square brackets around the type:",
-```
-
-Recommendation: use the longer block. The extra three lines buy clarity and reduce accidental over-filtering.
-
-### Parser quality gate recommendation
-
-Add deterministic snapshot rejection to `shouldAcceptWorkspaceMemoryCandidate()`.
-
-Keep this conservative. Reject obvious snapshots, not every number.
-
-Suggested first-pass rules:
-
-```ts
-// Session-specific progress snapshots, not durable memory.
-if (entry.type === "project") {
-  if (/\b\d+\s+tests?\s+pass(?:ed)?\b/i.test(text)) return false;
-  if (/\b\d+\s+suites?\b/i.test(text)) return false;
-  if (/\b\d+\s+(?:files?|文件)\b/i.test(text)) return false;
-  if (/\bphase\s*\d+(?:\s*[-–]\s*\d+)?\s+(?:completed|done|finished)\b/i.test(text)) return false;
-  if (/已完成\s*Phase\s*\d+(?:\s*[-–]\s*\d+)?/i.test(text)) return false;
-}
-```
-
-Do not reject stable `reference` values containing numbers. These must pass:
-
-```text
-Admin PIN 是 456123
-Scrypt 參數必須是 N=16384, r=8, p=1
-```
-
-For `feedback`, do not broadly reject ports yet. A port issue can be useful if it explains a recurring failure. Let staleness prune it, unless the text clearly says the issue was resolved. A future parser rule can reject resolved temporary env notes, but the current evidence is not enough to safely block all port-related feedback.
-
-### 5. Integration with storage-time dedup/staleness
-
-Prompt-level guidance and staleness solve different problems.
-
-Staleness is cleanup after bad or aging facts are already stored. Prompt guidance prevents low-value facts from entering the store in the first place. Parser filtering catches obvious misses when the prompt fails.
-
-Do not rely on staleness for exact counts.
-
-Why:
-
-- `maxEntries` is 28, so a few bad snapshots can evict useful facts before they age out
-- exact counts will churn every compaction and create near-duplicates
-- stale labels still consume render budget until pruning runs
-- users see noisy memory and trust the feature less
-
-Storage-time dedup/staleness remains required for facts that were good when written but later become outdated. Example: a config path that moves, a decision superseded by a better decision, or an unresolved bug that later gets fixed.
-
-Use this mental model:
-
-```text
-Prompt guidance      → prevent bad candidates
-Parser quality gate  → reject obvious bad candidates
-Storage dedupe       → merge repeated good candidates
-Storage staleness    → retire once-good candidates that aged out
-```
-
-### Updated priority
-
-The new content-quality evidence adds another P0 ingestion fix.
-
-Updated sequence:
-
-1. **P0a: Parser accepts bracketless candidate format and tests it.** Prevent silent data loss.
-2. **P0b: Prompt durable-content guidance.** Stop obvious snapshots at the source.
-3. **P0c: Parser rejects obvious low-durability `project` snapshots.** Backstop the prompt with deterministic filters.
-4. **P0d: Storage-time dedupe and staleness.** Still required for duplicate accumulation and lifecycle cleanup.
-
-### Final addendum 2 decision
-
-Add the durable-content guidance to the prompt and add conservative parser filters for obvious `project` snapshots.
-
-This does not replace storage-time dedupe or staleness. It reduces garbage before it reaches that layer. The store still needs to clean itself, but it should not be used as a trash compactor for facts we already know are temporary.

-# Workspace Memory Cleanup Migration Plan (v2)
-
-## Status: APPROVED (v3)
-
-## Problem Statement
-
-Audit of recent workspace memories found quality issues in pre-v1.2.1 stores:
-
-### Issue 1: Snapshot Violations (P0)
-
-| Workspace | Entry | Type |
-|-----------|-------|------|
-| opencode-record | `測試套件：1237 tests pass, 226 suites` | Test count |
-| opencode-record | `USB 同步：37 個文件（...）` | File count (Chinese) |
-| opencode-record | `pathology-playground...已完成 Phase 1-4` | Phase progress |
-| pathology-agent-reports | `Waves 1-5, 7 已完成，Wave 6 deferred` | Wave progress |
-
-**Root Cause**: These entries were created before P0c/P0d fix (08:02:32). Current code would reject them.
-
-**Risk**: Medium. Pollutes long-term memory, wastes tokens.
-
-### Issue 2: Sensitive Credentials (P0)
-
-| Workspace | Entry | Risk |
-|-----------|-------|------|
-| opencode-record | `Admin PIN 是 456123` | **High** - Raw credential |
-| Pre-cancer-atlas | `測試用戶名：shihlab，密碼：sushi` | **High** - Raw credential |
-
-**Root Cause**: No credential redaction in compaction extraction or storage normalization.
-
-**Risk**: High. Credentials sent to model in every compaction prompt.
-
-### Issue 3: Wave/Sprint Not Filtered (P0)
-
-| Pattern | Status |
-|---------|--------|
-| `Phase 1-4 已完成` | ✅ Filtered by P0c |
-| `Wave 1-5 已完成` | ❌ Not filtered |
-
-**Root Cause**: P0c filter only covers `Phase`, not `Wave/Sprint/Milestone/Task`.
-
-**Risk**: Medium. New snapshots still enter memory.
-
-### Issue 4: Duplicates (P1)
-
-| Workspace | Entry | Issue |
-|-----------|-------|-------|
-| Pre-cancer-atlas | `認證使用 Basic Auth...` x2 | Exact duplicate |
-| Pre-cancer-atlas | `IP 隱私...` x2 | Semantic duplicate |
-| Pre-cancer-atlas | `Cloud Run...` project + reference | Cross-type duplicate |
-
-**Root Cause**: `extractEntityKey()` only recognizes `opencode-agenthub`. Natural canonical dedup handles exact duplicates.
-
-**Risk**: Low. Wastes tokens but not dangerous.
-

-## Architect Review Failures (v1, v2)
-
-### v1 Failures
-
-| Issue | Problem |
-|-------|---------|
-| Regex | `Waves` not matched, Chinese `\b` unreliable |
-| Superseded entries | Would be deleted by `enforceLongTermLimits()` |
-| Credential redaction | Was migration-gated, must be always-on |
-| Wave filter | Deferred to future, must be now |
-| Over-broad | `Upload limit is 10 files` would be flagged |
-| Rationale | Only redacted `text`, not `rationale` |
-
-### v2 Failures
-
-| Issue | Problem |
-|-------|---------|
-| File context | `upload` matches `Upload limit`, false positive |
-| Explicit check | Missing `source === "explicit"` check before marking |
-| Credential regex | `\S+` captures through Chinese comma tail |
-| Filter location | Don't filter in `getFrozenWorkspaceMemory()` |
-
----
-
-## Proposed Solution (v3)
-
-### Architecture Principle
-
-```
-                    ┌─────────────────────────────────┐
-                    │ normalizeWorkspaceMemory()      │
-                    │                                 │

-                    │                                 │
-                    │  2. Mark legacy snapshots as    │
-                    │     superseded (migration-gated)│
-                    │                                 │
-                    │  3. Preserve superseded entries │
-                    │     in storage, exclude from    │
-                    │     render                       │
-                    └─────────────────────────────────┘
-```
-
-### Key Design Decisions
-
-1. **Credential redaction is always-on** - runs on every normalize, independent of migration ID
-2. **Snapshot marking is migration-gated** - one-time cleanup for legacy entries
-3. **Superseded entries preserved in storage** - but excluded from render
-4. **Type restriction for snapshots** - only `project` type, avoid false positives
-5. **Wave/Sprint/Milestone filter added now** - not deferred
-
----
-
-## Implementation
-
-### 1. Add Migration Tracking to Type
-
-```typescript
-// src/types.ts
-
-interface WorkspaceMemoryStore {
-  version: number;
-  workspace: { root: string; key: string };
-  limits: { maxRenderedChars: number; maxEntries: number };
-  entries: LongTermMemoryEntry[];
-  migrations?: string[];  // NEW: track applied migrations
-  updatedAt: string;
-}
-
-const MIGRATION_ID = "2026-04-26-p0-cleanup";
-```
-
-### 2. Snapshot Detection (Revised Regex)
-
-```typescript
-// src/workspace-memory.ts
-
-/**
- * Detect snapshot violations in text.
- * Only apply to 'project' type entries with source !== 'explicit'.
- */
-function isProjectSnapshotViolation(text: string): boolean {
-  // Test/suite counts
-  if (/\d+\s+tests?\s+pass(?:ed)?/i.test(text)) return true;
-  if (/\d+\s+suites?\s+(?:pass|fail)/i.test(text)) return true;
-  
-  // File counts (Chinese/English) - require sync/completion context
-  // And must NOT be a limit/maximum statement
-  if (/\d+\s*(?:個|个)?\s*(?:files?|文件)/i.test(text)) {
-    const hasSnapshotContext = /同步|synced|uploaded|downloaded|completed|generated|created|modified|processed|完成/i.test(text);
-    const hasLimitContext = /limit|max|maximum|min|minimum|supports?|allowed|per\s+(?:batch|request|upload)/i.test(text);
-    if (hasSnapshotContext && !hasLimitContext) return true;
-  }
-  
-  // Phase/Wave/Sprint/Milestone progress
-  // English: Phase 1-4 completed, Waves 1-5 done
-  if (/(?:phases?|waves?|sprints?|milestones?|tasks?)\s*\d+(?:\s*[-–]\s*\d+)?/i.test(text)) {
-    if (/completed|done|finished|完成/i.test(text)) return true;
-  }
-  // Chinese: 已完成 Phase 1-4
-  if (/(?:已完成|完成).{0,30}(?:phases?|waves?|sprints?|milestones?|tasks?)/i.test(text)) return true;
-  
-  return false;
-}
-```
-
-### 3. Credential Redaction (Always-On)
-
-```typescript
-// src/workspace-memory.ts
-
-/**
- * Bounded secret value pattern - stops at delimiters and Chinese punctuation.
- * Avoids capturing through Chinese commas: 密碼：sushi，用於測試
- */
-const SECRET_VALUE = String.raw`[^` + "`" + String.raw`'",，,\s]+`;
-
-/**
- * Multilingual credential labels.
- * These are used in both detection and redaction patterns.
- */
-const PASSWORD_LABELS = /password|passwd|pwd|密碼|密码|パスワード|비밀번호|contraseña|mot de passe|passwort/i;
-const USERNAME_LABELS = /username|user name|用戶名|用户名|ユーザー名|사용자명|usuario|utilisateur|benutzer/i;
-
-/**
- * Prefix patterns that capture label + delimiter together.

-
-### 5. Normalize with Always-On Credential Redaction
-
-```typescript
-// src/workspace-memory.ts
-
-// Preserve existing normalization behavior
-async function normalizeWorkspaceMemory(
-  root: string,
-  store: WorkspaceMemoryStore,
-): Promise<WorkspaceMemoryStore> {

-  result.entries = result.entries.map(entry => {
-    const text = redactCredentials(entry.text);
-    const rationale = entry.rationale 
-      ? redactCredentials(entry.rationale) 
-      : undefined;

-  
-  return {
-    ...result,
-    entries: [...processed, ...superseded],
-    updatedAt: nowIso,
-  };
-}
-```
-
-### 6. Extend P0c Snapshot Filter (Not Deferred)
-
-```typescript
-// src/extractors.ts
-
-// Add to isProjectSnapshotViolation() or equivalent filter
-
-// File counts - require snapshot context AND NOT limit context
-const FILE_COUNT_PATTERN = /\d+\s*(?:個|个)?\s*(?:files?|文件)/i;
-const FILE_SNAPSHOT_CONTEXT = /同步|synced|uploaded|downloaded|completed|generated|created|modified|processed|完成/i;
-const FILE_LIMIT_CONTEXT = /limit|max|maximum|min|minimum|supports?|allowed|per\s+(?:batch|request|upload)/i;
-
-if (FILE_COUNT_PATTERN.test(text)) {
-  if (FILE_SNAPSHOT_CONTEXT.test(text) && !FILE_LIMIT_CONTEXT.test(text)) {
-    return true; // snapshot violation
-  }
-}
-
-// Test/suite counts
-if (/\d+\s+tests?\s+pass(?:ed)?/i.test(text)) return true;
-if (/\d+\s+suites?\s+(?:pass|fail)/i.test(text)) return true;
-
-// Phase/Wave/Sprint/Milestone progress
-if (/(?:phases?|waves?|sprints?|milestones?|tasks?)\s*\d+(?:\s*[-–]\s*\d+)?/i.test(text)) {
-  if (/completed|done|finished|完成/i.test(text)) return true;
-}
-if (/(?:已完成|完成).{0,30}(?:phases?|waves?|sprints?|milestones?|tasks?)/i.test(text)) return true;
-```
-
-**Note**: Do NOT use bare `upload|download` as context. Use past-tense verbs or process states.

-
-## Test Cases
-
-### Credential Redaction (Always-On)
-
-| Input | Expected Output |
-|-------|-----------------|
-| `Admin PIN 是 456123` | `Admin PIN 是 [REDACTED]` |
-| `Admin PIN = 456123` | `Admin PIN = [REDACTED]` |
-| `Admin PIN 456123` | `Admin PIN [REDACTED]` |
-| `密碼：sushi` | `密碼：[REDACTED]` |
-| `密码：sushi` | `密码：[REDACTED]` |
-| `password: abc-123!` | `password: [REDACTED]` |
-| `パスワード：secret` | `パスワード：[REDACTED]` |
-| `비밀번호: secret` | `비밀번호: [REDACTED]` |
-| `測試用戶名：shihlab，密碼：sushi` | `測試用戶名：[REDACTED]，密碼：[REDACTED]` |
-| `密碼：sushi，用於測試` | `密碼：[REDACTED]，用於測試` |
-| Credential in rationale | Redacted in both text and rationale |
-| Explicit entry with PIN | Redacted, preserved |
-| `[REDACTED]` in text | No change (idempotent) |
-
-### Snapshot Detection
-
-| Input | type | source | Is Violation? |
-|-------|------|--------|---------------|
-| `1237 tests pass, 226 suites` | project | compaction | ✅ Yes |
-| `USB 同步：37 個文件` | project | compaction | ✅ Yes |
-| `Phase 1-4 已完成` | project | compaction | ✅ Yes |
-| `Waves 1-5 已完成` | project | compaction | ✅ Yes |
-| `Upload limit is 10 files` | project | compaction | ❌ No (has "limit" context) |
-| `Project supports 5 test suites` | project | compaction | ❌ No (no pass/fail) |
-| `Phase 1-4 已完成` | project | explicit | ❌ No (explicit preserved) |
-| Snapshot text | feedback | compaction | ❌ No (only project type) |
-| Snapshot text | decision | compaction | ❌ No (only project type) |
-
-### Migration Behavior
-
-| Test | Description |
-|------|-------------|
-| Run once | Migration ID added |
-| Run twice | No duplicate ID, entries unchanged |
-| Non-project entry | Not marked superseded |
-| Project snapshot | Marked superseded |
-| Explicit project snapshot | Not marked (source check before type) |
-| Credential in snapshot | Redacted, then marked superseded |
-
-### Integration Tests
-
-| Test | Description |
-|------|-------------|
-| `saveWorkspaceMemory()` | Superseded entries preserved in JSON |
-| `updateWorkspaceMemory()` | Credential redaction runs on second normalize |
-| New entry with PIN | Redacted on save (always-on) |
-| `normalizeWorkspaceMemory()` | Preserves workspace root/key, limits, updatedAt |
-| Memory render | Superseded entries excluded via `enforceLongTermLimits()` |
-
-### Extractor Tests
-
-| Input | Expected |
-|-------|----------|
-| `Upload limit is 10 files` | NOT a snapshot violation (has "limit" context) |
-| `USB uploaded 37 files` | Snapshot violation (has "uploaded" process context) |
-| `Project supports 5 test suites` | NOT a snapshot violation (no pass/fail context) |
-| `1237 tests passed` | Snapshot violation (test count with pass) |
-
----
-
-## Edge Cases
-
-| Case | Handling |
-|------|----------|
-| Entry is explicit + snapshot | Not marked (source check before type check) |
-| Entry has both snapshot + credential | Credential redacted, snapshot marked |
-| Entry is already superseded | Keep status, still redact credentials |
-| Migration runs twice | Skip if ID present |
-| Store has no migrations field | Create empty array |
-| `Upload limit is 10 files` | Not marked (has "limit" context) |
-| Password with punctuation `abc-123!` | Captured by bounded pattern |
-| Chinese comma after credential `密碼：sushi，用於測試` | Redact preserves `，用於測試` |
-| Simplified Chinese `密码` | Preserved as `密码：[REDACTED]` |
-
----
-
-## Implementation Order
-
-1. Add `migrations` field to `WorkspaceMemoryStore` type
-2. Add snapshot patterns to `src/extractors.ts` (not deferred)
-3. Add `isProjectSnapshotViolation()` to `src/workspace-memory.ts`
-4. Add `redactCredentials()` to `src/workspace-memory.ts`
-5. Add `runMigrationP0Cleanup()` to `src/workspace-memory.ts`
-6. Update `normalizeWorkspaceMemory()` with always-on redaction + migration
-7. Do NOT add filtering to `getFrozenWorkspaceMemory()` - filtering happens in `enforceLongTermLimits()`
-8. Add test cases for all patterns
-
----
-
-## What We Will NOT Do
-
-### Do NOT Add Project-Specific Entity Keys
-
-Cloud Run, Basic Auth, IP privacy — these are project-specific. Natural canonical dedup handles exact duplicates.
-
-### Do NOT Delete Superseded Entries
-
-Mark as `status: "superseded"`, preserve in storage, exclude from render.
-
-### Do NOT Gate Credential Redaction on Migration
-
-Credential redaction is always-on. Migration only marks legacy snapshots.
-
----
-
-## Summary
-
-| Issue | Priority | Solution |
-|-------|----------|----------|
-| Sensitive credentials | P0 | Always-on redaction |
-| Snapshot violations | P0 | Migration-gated marking (project type only) |
-| Wave progress not filtered | P0 | Add to extractors.ts now |
-| Project-specific duplicates | N/A | Natural dedup |
-
-**Credential redaction runs on every normalize.**
-
-**Snapshot marking is one-time migration for legacy entries.**
-
-**Superseded entries preserved in storage, excluded from render.**
-
-**Wave/Sprint/Milestone filter added now, not deferred.**
-
----
-
-## Multilingual Scope
-
-### Snapshot Detection: Chinese + English Only
-
-Do **not** add Japanese/Korean/Spanish/French/German snapshot regexes now.
-
-Reasons:
-- False positives silently suppress valid durable memories
-- Audit evidence only shows Chinese and English pollution
-- Words like "completed", "terminé", "abgeschlossen" can appear in durable process descriptions
-- Extraction is always-on, so every false positive becomes permanent blind spot
-
-Add languages only after seeing real polluted memories in those languages.
-
-### Credential Redaction: Add Multilingual Labels
-
-For credentials, false negatives leak secrets. Add high-signal multilingual labels now.
-
-**Password labels:**
-
-```typescript
-const PASSWORD_LABELS =
-  /password|passwd|pwd|密碼|密码|パスワード|비밀번호|contraseña|mot de passe|passwort/i;
-```
-
-**Username labels:**
-
-```typescript
-const USERNAME_LABELS =
-  /username|user name|用戶名|用户名|ユーザー名|사용자명|usuario|utilisateur|benutzer/i;
-```
-
-PIN remains language-neutral: `/\bPIN\b/i`
-
-### Memory Trigger Patterns: Add Chinese Expansion + Japanese + Korean
-
-#### Chinese Expansion
-
-Add common phrases:
-
-```typescript
-// Current: 记住/記住
-// Add: 记得/記得, 记下来/記下來
-
-/(?:^|\n)\s*(?:请|請)?(?:帮我|幫我)?(?:记住|記住|记得|記得|记下来|記下來)(?:这一点|這一點|这点|這點|这个|這個)?[:：,，]?\s*(.+)$/gim
-```
-
-#### Japanese Positive Triggers
-
-```typescript
-/(?:^|\n)\s*(?:覚えておいて|覚えて|忘れないで|メモして)[:：,，]?\s*(.+)$/gim
-```
-
-Note: `覚えておいて` must come before `覚えて` to prevent partial match in body.
-Note: `忘れないで` ("don't forget") is a positive memory request despite negative morphology.
-
-#### Japanese Negation
-
-```typescript
-/(?:覚えないで|記憶しないで|メモしないで)\s*$/u
-```
-
-#### Korean Positive Triggers
-
-```typescript
-/(?:^|\n)\s*(?:기억해줘|기억해|잊지 마|잊지마|메모해줘|메모해)[:：,，]?\s*(.+)$/gim
-```
-
-Note: `기억해줘` must come before `기억해`, `메모해줘` must come before `메모해` to prevent partial match in body.
-Note: `잊지 마` ("don't forget") is a positive memory request despite negative morphology.
-
-#### Korean Negation
-
-```typescript
-/(?:기억하지\s*마|기억하지마|메모하지\s*마|메모하지마)\s*$/u
-```
-
-#### Priority
-
-1. Chinese: `记得/記得`, `记下来/記下來` (small expansion)
-2. Japanese (full patterns + negation)
-3. Korean (full patterns + negation)
-4. Defer: Spanish/German/French (higher collision risk with normal text)
-
-### Tests Required
-
-**Credential redaction:**
-
-```text
-パスワード：secret → [REDACTED]
-비밀번호: secret → [REDACTED]
-contraseña: secret → [REDACTED]
-mot de passe: secret → [REDACTED]
-Passwort: secret → [REDACTED]
-```
-
-**Memory triggers (positive):**
-
-```text
-记得：这个项目使用 pnpm
-記下來：这个项目使用 pnpm
-覚えて: このプロジェクトは pnpm を使う
-覚えておいて: このプロジェクトは pnpm を使う
-忘れないで: このプロジェクトは pnpm を使う
-メモして: このプロジェクトは pnpm を使う
-기억해: 이 프로젝트는 pnpm을 사용한다
-기억해줘: 이 프로젝트는 pnpm을 사용한다
-잊지 마: 이 프로젝트는 pnpm을 사용한다
-메모해: 이 프로젝트는 pnpm을 사용한다
-메모해줘: 이 프로젝트는 pnpm을 사용한다
-```
-
-**Memory triggers (body extraction - must not include trigger suffix):**
-
-```text
-覚えておいて: このプロジェクトは pnpm を使う
-→ body is "このプロジェクトは pnpm を使う" (not "おいて: この...")
-
-기억해줘: 이 프로젝트는 pnpm을 사용한다
-→ body is "이 프로젝트는 pnpm을 사용한다" (not "줘: 이...")
-
-메모해줘: 이 프로젝트는 pnpm을 사용한다
-→ body is "이 프로젝트는 pnpm을 사용한다" (not "줘: 이...")
-```
-
-**Memory triggers (negation - should NOT trigger):**
-
-```text
-覚えないで 覚えて: temporary note only
-メモしないで メモして: temporary note only
-기억하지 마 기억해: temporary note only
-메모하지 마 메모해: temporary note only
-```
-
----
-
-## Memory Quality Bar (Prompt Improvement)
-
-### Problem
-
-Current extraction accepts "facts that were mentioned" instead of "facts that will change future behavior."
-
-Examples of low-value trivia:
-- `Cloud Run revision: pre-cancer-atlas-website-00066-j8c` — transient deployment state
-- `UI 要統一風格：兩個表格都要 scrollable，約 20 rows` — local implementation detail
-- Paths observed from code/logs without stable contract
-
-### Solution: Prompt Quality Bar
-
-Add to compaction memory extraction prompt:
-
-```text
-Memory quality bar:
-Extract only durable facts that will change future behavior: user preferences, decisions with rationale, stable constraints, or hard-to-rediscover references.
-
-Do not extract trivia: transient IDs/revisions, task progress, test/file counts, bare status updates, local UI details, or facts easily rediscovered from the repo.
-
-When unsure, skip it. Fewer high-signal memories are better than many low-value ones.
-```
-
-### Example Pair (Optional)
-
-If model still stores junk, add one example:
-
-```text
-Bad: Cloud Run revision: xyz-00066
-Good: Revision xyz-00066 is the last known good deploy before the auth regression.
-```
-
-### What This Captures
-
-| Keep | Reject |
-|------|--------|
-| User preferences | Transient IDs/revisions |
-| Decisions with rationale | Task progress, test/file counts |
-| Stable constraints | Bare status updates |
-| Hard-to-rediscover references | Local UI details |
-| | Rediscoverable facts |
-
-### Why Prompt Instead of Code Filters
-
-- Context matters: "Cloud Run revision" might be useful if framed as "last known good before regression"
-- Avoid regex whack-a-mole for every trivia pattern
-- Model can judge wording and context
-- Easier to iterate on prompt than code
-
-### Code Filters (Stay Minimal)
-
-Keep only hard invariants:
-- Credentials (security)
-- Obvious snapshots (test counts, phase progress)
-
-Do NOT add new filters for deployment revisions, status updates, or UI trivia. Let prompt handle those.
