feat: support timestamp="unset" to retain content without a date (#465)
* 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.

Website

This website is built using Docusaurus, a modern static website generator.

Installation

npm install

Local Development

npm start

This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.

Build

npm run build

This command generates static content into the build directory and can be served using any static contents hosting service.

Deployment

Using SSH:

USE_SSH=true npm run deploy

Not using SSH:

GIT_USER=<Your GitHub username> npm run deploy

If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch.
