-## [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.

-Use the read-only diagnostics CLI when you want to understand what memory is doing for the current workspace.
-
-| 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>` |
-
-Global options:
-
- `--workspace <path>` — inspect another workspace; defaults to the current directory.
- `--verbose` — show detailed diagnostics.
- `--json` — print machine-readable output where supported.
-
-Examples:
+For local development cleanup, use:

 ```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
+npm run cleanup:workspaces -- --dry-run
+npm run cleanup:workspaces -- --quarantine
 ```

-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.

-Maintainer-only diagnostics and cleanup commands are intentionally not documented here. Future work: move those internal commands to `docs/development.md`.

 # Release Notes

-## 1.5.4 (2026-05-02)
-
-### 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"]
-}
-```
-
-### Validation

 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.

-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 and slow future decay, but same-session and under-one-hour repeats do not stack reinforcement.

 - `maxEntries` of 28 provides good coverage without overwhelming
 - Entry text limits ensure entries stay concise

-## 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;
-const REINFORCEMENT_HALFLIFE_FACTOR = 0.85;
-const REINFORCEMENT_MAX_COUNT = 6;
-const WORKSPACE_DORMANT_AFTER_DAYS = 14;
-const DORMANT_DECAY_MULTIPLIER = 0.25;
-```
-
-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:
-
-| Type | Rendered cap |
-|------|--------------|
-| `feedback` | 10 |
-| `decision` | 10 |
-| `project` | 8 |
-| `reference` | 6 |
-
-Old or stale-marked memories are not hard-pruned by age; they lose rendered space through strength and cap competition. The deprecated `safetyCritical` field is preserved for compatibility but no longer affects strength or type caps.

-### Inspect Retention Health
-
-Use the diagnostics CLI to check memory health for the current workspace:
-
-```bash
-npx --package opencode-working-memory memory-diag status
-# or from a source checkout:
-npm run diag -- status
-```
-
-For detailed diagnostics, use `--verbose`:
-
-```bash
-npx --package opencode-working-memory memory-diag status --verbose
-```
-
-The status output includes overall health (OK/WARNING/DEGRADED), key metrics, and suggested next steps when attention is needed.

Ralph Chang	1847f63480	fix: owner scope in global unowned promotion Problem: clearPendingMemories() and recordPromotionRejections() would incorrectly clear or mutate owned entries during global unowned promotion. Fixes: 1. clearPendingMemories() now respects owner/unowned scope: - global clearUnowned only clears unowned same-key entries - owned same-key entries are preserved - explicit global clear-all-by-key fallback still works 2. recordPromotionRejections() now has includeUnownedOnly option: - global unowned rejection only increments/exhausts unowned entries - owned same-key entries are preserved 3. Added regression tests: - global unowned clear keeps owned same-key entries - global unowned rejection only exhausts unowned same-key entries Tests: 182 pass, 0 fail	2026-04-28 12:27:46 +08:00
Ralph Chang	8b21325469	fix: cross-process lock stale judgment and heartbeat Problem: CI test "updateJSON serializes writes across separate node processes" was failing with expect 100 but got 89/97. The root cause was isLockStale() being too aggressive - it could mistakenly delete locks held by other processes. Fixes: 1. isLockStale() now uses mtime only - fresh locks are never stale 2. Added heartbeat mechanism during lock hold to support long updaters 3. Removed PID check that was unreliable in CI/containers 4. Fixed ENOENT race when lock is released between EEXIST and stat Tests: 180 pass, 0 fail	2026-04-28 12:24:56 +08:00
Ralph Chang	b846b34e30	feat: implement Plan 1 - Critical Stability fixes Wave 1: Storage and Journal Safety - Add frozen cache TTL (1h) and size bounds (50 sessions) - Add pending journal source-aware retention (compaction-only TTL) - Add inter-process file lock with stale recovery - Move processLatestUserMessage to first transform (after isSubAgent guard) Wave 2: Promotion Ownership and Bounded Rejection - Add pendingOwnerSessionID/pendingMessageID metadata - Add owner-aware pending journal clearing - Add explicit/manual bounded retry (max 3 attempts) - Fix session.deleted cleanup idempotency Wave 3: Normalize, Security, and Cache Hardening - Fix load-time write loop (only write on security/migration change) - Add deterministic sort tie-breaker (createdAt -> id) - Add Bearer token redaction - Add processed message cache bounds - Remove priorityWithFreshness dead code Tests: 180 pass, 0 fail	2026-04-28 11:59:29 +08:00
