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.
