chore(wolf): update buglog and session state

buglog.json: corrected bug-1480/1481 (stale "not yet fixed" entries, code
landed same day the entries were written); bug-1483/1484 fixed; bug-1485
investigated, downgraded to low-priority/environment-flake.

"fix": "NOT FIXED. Task 6.3 round-2 remediation implemented exactly what the round-1 reviewer asked for (_wait_for_standbys mirroring test-heartbeat-tolerance.sh's two-phase primary+standby gate, a heartbeat_interval_ms-justified 3s settle delay, and a fresh wait_for_port re-probe of the primary before yielding the fixture) but this did not close the flake because the underlying failure is the primary process disappearing, not merely its port being slow to open -- no test-side wait can outlast a process that is gone. Reported BLOCKED back to the task's parent controller rather than continuing to chase a C-level root cause outside this task's explicit boundary (controller-side C changes forbidden). Next step for whoever picks this up: capture stderr (not DEVNULL) from a real pytest-triggered failure to get an ASAN report or signal number, and/or strace the primary process across a live failing pytest run to see whether/why its listening socket closes.", "fix": "UPDATE 2026-08-01 -- investigated per this entry's own \"next step\" (capture stderr instead of DEVNULL, re-attempt). Redirected each node's stderr to deploy_dir/logs/<name>.stderr.log (permanent change to test_e2e_live_ha_push.py, replacing the DEVNULL redirect that left this entry's original investigation with no diagnostic) and added an XCE_KEEP_DEPLOY_DIR=1 debug env var to preserve deploy_dir across the fixture's own cleanup for inspection. Ran the live test 40 times total in this environment: 25 baseline (idle sandbox, load avg ~2/22 cores) + 15 more with a concurrent `xce-build.sh controller debug` compile racing for CPU (separate build.dbg dir, so it could not clobber the xce.build controller binary the test depends on -- unlike bug-1486's same-dir clobber shape). Result: 40/40 PASSED, 0/120 captured stderr logs (3 nodes x 40 runs) non-empty -- no crash, no ASAN report, in any run. Could NOT reproduce the ~24/25 failure rate from the original investigation despite matching the documented repro shape exactly (same binaries, same fixture code, same pytest invocation).\n\nNOT marking fixed -- absence of reproduction here is not proof of absence of the underlying bug, and this session's single concurrent compile is a much lighter contention scenario than the real multi-session sandbox reality bug-1486 documents (several concurrent AGENT SESSIONS, potentially each running their own live 3-node cluster). Leading hypothesis (unconfirmed): the original ~24/25 failure rate was itself a symptom of resource contention from OTHER concurrent sessions on the shared sandbox during that investigation (CPU starvation delaying the primary's post-election warmup past _POST_ELECTION_SETTLE_S, or an OOM-adjacent condition killing the freshly-forked primary outright) rather than a bug in the promotion path reachable in isolation -- consistent with the original investigation's own \"pytest's process tree somehow makes far more likely\" framing, since pytest's subprocess tree carries more memory/fd overhead than the bare python3 scripts that never reproduced it there either.\n\nDowngraded to low-priority/environment-flake, left OPEN. The stderr-capture infrastructure is now permanently in place (not reverted) so the next real live failure -- in pytest, in a genuinely contended multi-session sandbox, or in CI -- captures an actual ASAN report or signal instead of DEVNULL silence, which is what would actually close this out.",
