Oliver Kieselbach 7a3516e570 feat(observability): IME pattern-drift loop — nothing the log tracker skips or stops matching stays silent: the agent keeps cumulative tracker health counters and a per-pattern match histogram (restart-safe in ImeTrackerState), reports ime_* keys in agent_metrics_snapshot (files tailed, backlog bytes, lines read, matches, oversized/timeouts/budget breaks/held tails/unanchored), raises a one-shot immediate-upload ime_tracker_degraded Warning on the first pass that skipped work, and emits ime_pattern_hits at termination (every enabled pattern, zeros included, IME version); the backend folds the histogram into the permanent per-IME-version ImePatternStats table (built-in IDs only, plausible version only, one partition read + one transactional batch) and evaluates drift without a hard-coded list — baseline = the version with the most reporting sessions (≥100), expected = ≥80 % hit rate there, drift = an expected pattern matched in none of ≥25 sessions on a newer version — raising ImePatternDriftSuspected once per version×pattern (ETag-stamped, dual-registered in the web ops-event list with a new guard test); GET metrics/ime-pattern-health (GlobalReadOrAdmin) + Global Admin → Metrics → IME Pattern Health matrix (drift/silent/low/few cells, open alerts, retired patterns) + session-page "IME Tracker" rows (latest snapshot by max sequence) + MCP get_ime_pattern_health (GA/Reader) ...

cmtrace-time-resolution.md

fix(security): CmTraceLogParser parses in linear time (first open / last parseable trailer, timeout-backed trailer regex) instead of a greedy .* regex that backtracked quadratically on hostile lines without a timeout; agent multiline buffer gains a 1 MB char cap next to the 100-line cap, both logged at Warning, and the tail of a dropped entry is skipped instead of raw-matched
