* fix: recover embedding after transient health failure
* refactor(embedding_store): remove provider_success_count and simplify health recovery logic
- Deleted provider_success_count attribute and related methods across embedding and file stores
- Updated _recover_after_real_request to rely solely on is_healthy flag for recovery decisions

- Clarify coding agent guidance for keeping changes small and consistent
- Revise project principle descriptions for clarity and modern terminology
- Expand repository map with detailed component and folder explanations
- Add configuration and CLI usage instructions, including syntax and merging rules
- Elaborate on component, step registration, and application lifecycle processes
- Define jobs, steps, and state handling conventions for stateless design
- Specify workspace and file safety policies, including path restrictions and locking
- Update validation commands and testing environment recommendations
- Clarify coding and test conventions, including style and dependency policies
- Distinguish documentation boundaries and update website content contribution notes
- Reinforce change guardrails to avoid breaking backward compatibility and data loss
- Improve svg diagram formatting and textual details in auto dream and proactive flow image
* style(docs): fix font-family syntax in SVG style definitions
- Correct quotation marks around font-family names in memory-as-file.svg

- Ensure consistent CSS style formatting within SVG files for better rendering fidelity
* docs: add ReMe blog to news
* style(docs): inline svg styles and improve text formatting
- Convert multiline SVG style tags into single-line for compactness in multiple figures
- Remove redundant line breaks in subtitle text elements for consistency
- Shorten descriptive texts in SVG figures for clarity and conciseness
- Adjust font sizes and text for better readability in SVG elements

* feat: simplify local links and support line anchors
* fix: align line anchor tests with CI lint
* fix: preserve local links across file moves
* fix: encode markdown paths when rewriting links
* refactor(read): keep explicit line range parameters
* fix: simplify legacy link predicate compatibility
* docs: align local link behavior with implementation
* fix: skip unsupported markdown destination escapes
* fix: normalize workspace link paths across platforms
* fix: bound markdown link scanning
* fix: keep local link processing linear
* docs: clarify permissive markdown link parsing
* fix: handle local link processing failures
* refactor: limit file links to wikilink syntax
* docs: align wikilink contract with implementation
* fix: normalize dream and neighbor paths on Windows
* fix: resolve workspace path for neighbor expansion
* feat(file_store): upgrade FAISS to HNSW index with async reindex and path constraint
- Replace IndexFlatIP with IndexHNSWFlat for better recall/speed tradeoff
- Add dynamic efSearch (limit * 5) scaled to query request size
- Add async_reindex option: background rebuild with generation-based invalidation
- Extract _delete_nodes() in LocalFileStore for subclass reuse
- Add unit tests for file store consistency
* fix: resolve pylint warnings in faiss store and test file
* refactor(file_store): replace generation-based reindex with event-flag worker
- Replace _reindex_generation/lock/task with a single long-lived worker
coroutine consuming an asyncio.Event flag; repeated submissions coalesce
- Use local index reference in vector_search to avoid TOCTOU on self._faiss_index
- Pass index explicitly to _set_ef_search for consistency
- Track _index_writes to re-arm reindex after concurrent writes
- Update tests to match new internal API
* fix: resolve pylint too-many-return-statements and implicit-booleaness warnings
* feat(file_store): add refine maintenance hook and incremental embedding backfill
- Add refine() idle-time maintenance hook to BaseFileStore/LocalFileStore
- FaissLocalFileStore: incremental vector add on backfill instead of full rebuild
- Dynamic tombstone compaction threshold scaled by index size
- Add RefineStoreStep with daily cron job (refine_store_cron)
- Enable faiss backend and embedding_store by default in default.yaml
- Add unit tests for faiss index maintenance
* chore(deps): promote faiss-cpu to core dependencies
faiss backend is now the default file_store, so faiss-cpu moves from
the optional [core] extra to the base dependencies list.
* feat: rename refine_store to optimize_index and add vecdb_path_constraint
- Rename refine_store step to optimize_index with cron job scheduling
- Add vecdb_path_constraint to file_store components
- Update default.yaml with optimize_index_cron and faiss backend comment
- Update memory_search docs (en/zh) for FAISS vector management
- Update unit tests for index maintenance
* feat(faiss): add embedding digest to reject stale sidecar after partial dump
Add _chunks_embedding_digest() that computes an order-independent SHA-256
over (chunk_id, float16 embedding) pairs. The digest is written into the
idmap sidecar at dump time and verified at load time. A mismatch means the
sidecar vectors belong to a different chunk generation than the authoritative
JSONL — detectable even when the live-ID set is unchanged (same-ID in-place
update crash window).
Add test_faiss_rejects_stale_sidecar_after_partial_dump reproducing the
crash-between-writes scenario and asserting digest-based rejection.
Compress verbose docstrings/comments in existing tests for pylint line
budget.
