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.

[1.3.0] - 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• Promotion classification: promoted, absorbed, superseded, rejected.
• Remove absorbed/superseded keys from rejected set to avoid duplicate rejection tracking.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.
• 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.

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• Active vs superseded boundary when promoting pending memories (superseded entries no longer block promotion of same-key active memories).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

• Clarified superseded accounting semantics: P0 emits events only, does not archive newly superseded records.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.

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.
• Multi-process writes to the same workspace are not fully serialized.

[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.
