Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[1.4.0] - 2026-04-28

Added

• Unified memory quality gate in src/memory-quality.ts as the single source of truth for all memory quality rules.
• CRITICAL MEMORY RULES in compaction prompt with explicit good/bad examples.
• Auto-supersede migration 2026-04-28-quality-cleanup that marks low-quality compaction memories as superseded on first load.

Changed

• Memory quality rules now apply to all memory types, not just project entries.
• Compaction prompt explicitly instructs model that most compactions should produce zero memories.
• Low-quality compaction memories (progress snapshots, implementation notes, session-internal notes) are automatically superseded during workspace memory normalization.

Migration Notes

• Existing low-quality source: "compaction" entries will be marked as superseded once on first load after upgrade.
• Explicit and manual memories are never affected by quality cleanup.
• Superseded entries are retained on disk with quality_cleanup tags for audit purposes.
• Migration is idempotent and runs exactly 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• Retained source-aware pending memories until they are actually promoted, absorbed, superseded, or rejected.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.
