fix: cut log noise and add severity-based searching

[bmdavis419]

Problem

Live testing of the new first-class logs feature on three running boxes (columbia, liles-box, media-bot) found the durable streams flooded with noise:

1. Heartbeat flood: executor daemon: reachable (remote) was logged by every 20s reconcile cycle — 17,360 of 17,419 agent events in 24h (99.7%) on media-bot, >94% of all events on every box. A plain tx9 logs <box> showed 200 identical lines.
2. Executor duplicate line: nearly all executor events were the identical [executor] MCP session mode {...} line repeated 2–4× every ~11 minutes.
3. Multi-line explosion: multi-line Hermes records (skill files, shutdown diagnostics with full ps output) split into 50–104 per-line events sharing one timestamp; grep returned contextless fragments, plus truncated duplicates ([Tool lo, [Tool loop warning: same_too) from re-reading the mid-write tail of the active log file.
4. No severity field: no way to ask for "operational warnings only" — errors had to be found by grepping WARNING.
5. Smaller bugs: loadavg-like fragments parsed as 1970-01-01 timestamps (invisible to every --since); ~80% of codex events had empty messages.

Fixes

• guest/hb: reconcile-loop Executor reachability reporting is now state-change-only, tracked in a /tmp state file that resets with the container. Interactive paths (hb up, etc.) always print and never consume the loop's state, so a manual invocation can't swallow the next flip notification.
• guest/tx9-logs capture: consecutive identical lines collapse into one structured event plus an output_repeated summary with the count (60s window, 1000-repeat cap). Raw text logs and the mirrored stdout/stderr stay byte-faithful. Blank lines no longer become structured events.
• guest/tx9-logs query: Hermes raw-log continuation lines (no leading timestamp or level token) group into the record that introduced them, capped at 1000 lines/1MiB; the possibly mid-write final line of the active file is skipped (kills truncated duplicates); text output renders multi-line messages with indented continuations.
• Severity: tx9.event.v1 gains an optional level field (debug|info|warn|error), best-effort parsed from python-logging prefixes, level= tokens, and native record fields (level/levelname/severity), omitted when unknown — backward compatible. New --level flag on tx9 logs and tx9 logs export keeps that level and above; unleveled events count as info, so --level warn silences unleveled chatter while --level info shows everything.
• Timestamps: numeric values below epoch 1e9 (pre-2001) are rejected, so loadavg fragments fall back to file-mtime ingest time instead of 1970.
• Empty events: native-history records with no extractable text are dropped.

Impact on media-bot: ~17k noise events/day → ~60 real ones.

Tests

• tests/regressions-hb-workload.sh: state-change-only reporting across reachable→unreachable→reachable flips; interactive up always reports; reconcile still fails loudly when unreachable.
• tests/regressions-logs.sh: capture dedup + output_repeated counts + raw-log fidelity; continuation grouping; active-file partial-tail skip; epoch-timestamp rejection; level parsing/filtering incl. bogus-value drop on schema-v1 records; multi-line text rendering; empty-message drop (flips one existing assertion that pinned the old behavior).
• internal/cli/cmd_logs_test.go: --level in helper args, omitted when unset, value validation.

make check passes (syntax, shellcheck, static contracts, shell regressions, go vet/build/test).

Notes

• Old boxes: passing --level to a pre-upgrade in-box helper fails with the existing "upgrade the box" guidance; the flag is never passed when unset.
• Timestamp-less warning lines grouped under one record still share the mtime-based fallback timestamp — inherent to timestamp-less sources.

Note

Add severity-based log filtering and suppress steady-state reconcile log noise

• Adds --level flag (debug/info/warn/error) to tx9 logs and tx9 logs export; unlabeled events are treated as info. Level is validated in cmd_logs.go and forwarded to the Python helper.
• Parses and normalizes severity from common log formats (prefix tokens, key-value pairs) in guest/tx9-logs, annotating structured events with a level field used for threshold filtering.
• Collapses consecutive duplicate structured events within a time window into a single output_repeated summary; raw bytes and mirrored outputs remain unmodified.
• Groups multi-line raw log records (e.g. Hermes tracebacks) into single events with timestamp fallback and level detection; partial active-file tail records are withheld until complete.
• Suppresses repetitive executor reachability messages in the hb reconcile loop via _steady_report, which persists last-seen state and only logs on transitions when HB_STEADY_QUIET=1.
• Behavioral Change: reconcile no longer logs executor reachability on every cycle; only state transitions produce output.

Greptile Summary

This PR reduces log noise and adds severity-based log filtering. The main changes are:

• Added --level filtering for log queries and exports.
• Added best-effort severity parsing for structured and raw log events.
• Collapsed repeated captured output into repeat-count events.
• Grouped Hermes multi-line raw records into single events.
• Suppressed steady-state executor reachability logs in the reconcile loop.
• Added safer timestamp handling and empty-message filtering.

T-Rex Logs

What T-Rex did

• T-Rex produced a proof for a posted P1 finding.
• T-Rex performed general-contract-validation-proof work by running regression checks, inspecting logs, and validating the focused repro and downstream test results, which show the regression command exit code 4, the focused repro reporting three matching stdout events before jq returns with JQ_EXIT: 4, and the heartbeat workload and CLI tests passing (exit code 0).

   Final JSONL Record Is Hidden

   When the active structured log ends with a valid JSON object that was flushed without a trailing newline, this branch drops the whole record. That can hide the last structured event from queries and exports even though the record is already present in the file.

   • Contains supporting evidence from the run (text/x-python; charset=utf-8).

   Repro: command transcript showing valid bytes are omitted by query and export

   • Keeps the command output available without making the summary code-heavy.

   Logs regression script fails because jq -e select assertion returns 4 after later non-matching records

   • Bug
     • The explicit logs regression test plan cannot pass on the head checkout. In the first capture/redaction subcase, executor.jsonl contains matching stdout output records, but the assertion uses jq -e 'select(.source == "executor" and .stream == "stdout" and .type == "output")' file >/dev/null. Since later records in the same JSONL stream are stderr/event records that do not match and produce no output, jq exits 4 even though earlier matching records were emitted.
   • Cause
     • The test assertion relies on jq -e select(...) over a multi-record stream. jq's -e status is based on the last output status, and a later input that produces no output makes the command fail despite earlier matches.
   • Fix
     • Change the assertion to aggregate over the stream, for example jq -e 'any(inputs?; .source == "executor" and .stream == "stdout" and .type == "output")' with appropriate input handling, or use jq -e '[. | select(...)] | length > 0' under slurp mode (-s).

3. General comment

   logs regression script fails because jq -e select assertion depends on the final JSONL record

   • Bug
     • tests/regressions-logs.sh fails at the first executor stdout JSONL assertion even though matching stdout output records exist. The command uses jq -e 'select(...)' file >/dev/null over the full JSONL stream. With jq -e, the process exit status is based on the last output value; because the final input record is process_exit and does not match the select, jq exits 4.
   • Cause
     • The shell test uses jq -e select(...) directly on a multi-record JSONL file where later non-matching records can make the assertion fail despite earlier matching records.
   • Fix
     • Change the assertion to aggregate matches or terminate successfully on the first match, for example jq -e 'any(inputs?; .source == "executor" and .stream == "stdout" and .type == "output")' with suitable JSONL handling, or jq -e 'select(...)' file | grep -q . without relying on jq's final-record exit semantics.

4. General comment

   regressions-logs.sh fails on a valid JSONL stream because jq -e select returns 4

   • Bug
     • The explicit log regression script aborts at its first JSONL validation. The generated executor.jsonl contains multiple records matching .source == "executor" and .stream == "stdout" and .type == "output", and the focused repro shows jq prints those matching objects. However, the command still exits 4, causing set -e to abort tests/regressions-logs.sh before the remaining deduplication, multiline, timestamp, and level-filtering coverage can run.
   • Cause
     • The changed test script uses jq -e 'select(...)' file >/dev/null. With -e, jq's exit status is based on the last result processed, not merely whether any earlier input matched. Because later records such as stderr/process_exit do not match the select predicate, jq exits 4 despite earlier matches.
   • Fix
     • Change the assertion to aggregate matches before applying -e, for example: jq -e 'any(.source == "executor" and .stream == "stdout" and .type == "output")' "$executor_root/logs/executor.jsonl" >/dev/null, or collect/select then test length > 0 with slurp mode.
