* feat: support timestamp="unset" to retain content without a date When callers retain timeless content (e.g. fictional documents, static reference material), passing timestamp="unset" now skips the utcnow() default so mentioned_at is stored as NULL instead of an artificial date. - HTTP: validate_timestamp recognises "unset" sentinel and threads it through api_retain as event_date=None (key present, value None), which the orchestrator distinguishes from key-absent (still defaults to now) - Orchestrator: new branching logic separates "key absent" → utcnow() from "key present but None" → no date - types.py: RetainContent.event_date and ProcessedFact.mentioned_at are now datetime | None; removed the unused _now_utc factory - fact_extraction.py: all event_date params accept datetime | None; _build_user_message emits "Event Date: Unknown" when None; removed mentioned_at from the Fact LLM response model (LLM never sets it) - embedding_processing: skip date suffix when fact_date is None - entity_resolver: COALESCE(event_date, now()) for first_seen/last_seen so entities table NOT NULL constraint is preserved - link_utils: skip temporal linking for units without event_date - Migration aa2b3c4d5e6f: DROP NOT NULL on memory_units.event_date - Tests: test_retain_no_timestamp and test_retain_omit_timestamp_defaults_to_now - Docs + OpenAPI + TypeScript client updated * refactor: replace _TIMESTAMP_UNKNOWN sentinel with plain string comparison The sentinel object() was only needed to distinguish "unset" from None at the boundary — but since the field type is datetime | str | None, "unset" can pass through the validator unchanged and be compared directly. * chore: regenerate OpenAPI spec and clients after timestamp type change timestamp field is now datetime | str | None to accept the "unset" sentinel value. |
