From 78cc54884641aaa4bf3d5ffc59b0af7e44dd2393 Mon Sep 17 00:00:00 2001 From: Ragnor Comerford Date: Sun, 3 May 2026 13:10:28 +0200 Subject: [PATCH] tests: composite agent-lifecycle integration test (MR-858) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements MR-858 ahead of the rest of the MR-857 epic: the deterministic narrative test counterpart to MR-783's randomized harness. `tests/agent_lifecycle.rs::agent_lifecycle_init_load_branch_merge_time_travel_optimize_cleanup` walks the canonical agent flow end to end: 1. init repo with TEST_SCHEMA 2. load_jsonl seed data (4 Person + 2 Company nodes; Knows + WorksAt edges) 3. branch_create feature off main 4. mutate on feature: single-statement insert (Eve) + multi-statement insert+edge (Frank knows Eve) 5. query on feature: total_people / friends_of (traversal) / unemployed (anti-join) / friend_counts (aggregation) 6. mutate on main (set Bob's age) — sets up non-conflicting merge 7. branch_merge feature → main; verify version advance 8. query post-merge: confirm Eve visible on main (from feature) + Bob visible (from main mutation, carried through merge) 9. snapshot_at_version(pre_merge_version): time-travel still sees pre-merge state (4 Persons, no Eve) 10. optimize the post-merge graph; verify reads still work + counts unchanged 11. cleanup with --keep 10 --older-than 3600s (no-op for this short test, but exercises the call path) 12. drop + reopen; verify all counts + branch list consistent; confirm read path works post-cleanup-reopen **Known limitation surfaced**: post-optimize mutation path in step 11 hit `ExpectedVersionMismatch` because `optimize_all_tables` advances per-table Lance HEAD without updating the `__manifest` pin (`db/omnigraph/optimize.rs:77`), and something between optimize and re-open writes a higher version row to `__manifest`. Test documents this and defers full coverage to MR-859 (`omnigraph optimize` + `cleanup` integration coverage), keeping the read-path-after-cleanup assertion which is the headline operator concern. Test runs in <1s. ~672 workspace tests pass with --features failpoints; no regressions.
