liminis-context-graph v0.17.0 — ingestion time on every record, and a new home

[verveguy]

v0.17.0 records when each record was ingested, separately from the event time you supply. It moves to lbug 0.21.1 and to version 3 of the MCP library. It's the first release from the project's new home under liminisapp, with docs at docs.liminis.app.

It's a minor release because the first start adds a column and backfills it. There's no storage migration: the storage version stays 47.

Upgrading

The first start after upgrading runs two one-time steps. Both are logged, and a large graph starts slower that one time. Later starts do neither.

• The ingested_at addition (Record ingest time separately from reference_time #673). Episodes, entities and edges each gain an ingested_at column. Existing rows are backfilled from the WAL entry that created them where the WAL still has one, and from created_at otherwise. The created_at fallback is approximate, because for older records it held the event time.
• A full-text index rebuild. The FTS marker from 0.16.3 records the exact lbug version, so the move to 0.21.1 rebuilds the three indexes once. The index format didn't change.

ingested_at on episodes, entities and edges (#673)

• What it records: the time the service first wrote the record, kept separate from the caller-supplied event time (reference_time → valid_at / created_at).
• How it behaves: it's set once and never caller-supplied. It survives WAL rebuild, recovery, checkpoint restore and dump compaction.
• Where it appears: on every episode, entity and relationship read. It's also accepted in the fields projection of knowledge_get_episodes and knowledge_list_entities.
• What's unchanged: created_at, valid_at and all ordering.

Also changed

• lbug 0.21.0 → 0.21.1 (chore(deps): non-major Rust updates, including lbug 0.21.0 → 0.21.1 #676). The extensions and storage version are unchanged.
• MCP library rmcp 2.2 → 3.5 (chore(deps): bump rmcp 2.2 → 3.5 #680). It's a major version bump, but the tool surface is unchanged.
• New home (Point live references at liminisapp and docs.liminis.app after the org move #682). Metadata, CLI help and docs point at liminisapp/liminis-context-graph and docs.liminis.app. Old URLs redirect.
• Dependency updates, including quinn-proto 0.11.19 (a security advisory).

What was verified

• MCP, because of the major library bump: stdio initialize, the tool list, paged and projected reads, writes, error codes, and attached mode, all run against the CI-built macOS release binary.
• Upgrade over a 0.16.4 database (a copy of a real notebook): every row was backfilled, existing data was byte-identical, the WAL was untouched, and the second and third starts did no rework.
• macOS: linkage checked, and the sidecar-gated replay battery ran with no skips, with timings level with 0.16.4 when run alternately.
• CI: the full Rust suite, all six real-corpus end-to-end jobs, Windows with real index creation and queries, and release builds for all four targets with pinned extensions. No check was cancelled.
• Published artifacts: all four archives pass their checksums, every bundled extension matches its pinned hash, and the published macOS binary reports 0.17.0 and serves all 46 tools over MCP.
