- aux_config: drop session_search from _AUX_TASKS and remove stale test
(PR #27590 removed auxiliary.session_search from DEFAULT_CONFIG)
- compression_boundary_hook: set compressor._last_compress_aborted=False
on MagicMock so the post-compress abort branch (PR #28117) doesn't
short-circuit before the session-id rotation under test
- kanban_dashboard_plugin: use consecutive_failures=3 so severity stays
'error' (failure_threshold default dropped from 3 to 2 in d9fef0c8a,
so failures=5 now crosses the critical floor of 2*2=4)
- cli_manual_compress: accept force kwarg on DummyAgent._compress_context
(cli._manual_compress now passes force=True)
When _compress_context rotates session_id (compression split), fire
on_session_start(new_sid, boundary_reason="compression",
old_session_id=<old>) on the active context engine. Plugin engines
(e.g. hermes-lcm) use this to preserve DAG lineage across the rollover
instead of re-initializing fresh per-session state.
Built-in ContextCompressor.on_session_start accepts **kwargs and ignores
them — no behavior change for default users.
Closes hermes-lcm#68 symptom: after Hermes compressed and minted a new
physical session, LCM was treating the split as a fresh /new and losing
continuity (compression_count: 1, store_messages: 0, dag_nodes: 0).
Credit: @Tosko4 (PR #13370) — minimized scope to the boundary_reason
signal only; the broader session-lifecycle refactor will be taken in
separate PRs if justified by concrete plugin need.
