WalkthroughThe change adds 17 liquidity metrics across latency, reliability, infrastructure, and rebalance families. New sample builders convert performance reports into metric samples. A supervised task refreshes latency, reliability, and infrastructure metrics every 60 seconds and rebalance metrics every fifth cycle. Collection failures and timeouts preserve the previous family and success timestamp. Documentation, parity tooling, fixtures, and tests cover the new metrics and collector behavior. Priority: ➖ Normal Merge Risk: 🔵 Low · up to The new per-chain block-lag metrics can let the dashboard’s freshness indicator hide a stalled chain behind a healthy one. Correct the panel or explicitly accept this bounded monitoring risk before relying on the dashboard. Pre-merge checks |

@coderabbitai I replied to the one minor finding and kept the sequential collectors on purpose (reason in the thread). Please re-review this head. |

This PR adds a supervised 60 s task, liq-performance-refresh, that publishes the liq_ performance families (hedge latencies and open exposure, reliability, infra, rebalance timings) from the bot's own /metrics. Each family is built from the same loaders and DTOs that the /performance/* endpoints serve. A collector that fails or passes its 30 s timeout keeps its last family, and its freshness timestamp stops advancing. Block lag and poll series get a chain label, and the parity script ignores the infra names because the exporter's infra collector is broken.
Overall it is in good shape. The task is isolated in the auxiliary supervisor, failure and timeout keep the last good family, the builders are pinned by goldens generated from the exporter, and the tests cover the empty database, the fifth-cycle rebalance cadence, a failing loader, and a timeout. No blockers. Two minor points: the documented live parity check will report false differences for the new cached families, and the infra family keeps advancing liq_block_lag_sampled_ts_seconds while a chain's lag is unknown, unlike the native gauge. The earlier threads (docs step 3, the SPEC label exception, the staleness panel, the infra duplication) are resolved as follow-ups and are not repeated here.

Part of RAI-3090.
Publishes the
liq_performance families from the bot: hedge latencies, reliability, infra, and rebalance timings. Item 3 of the RAI-2998 stack, part 2 of 3.Live effect: the bot's
/metricsgainsliq_hedge_latency_ms*,liq_open_exposure_*,liq_failure_event_count_24h,liq_job_queue,liq_block_lag_*,liq_poll_*,liq_dependency_*,liq_rebalance_stage_ms, andliq_attestation_last_ms· Risk: low to medium (a new 60 s task runs the same SQLite loaders the exporter already calls every minute, so that load doubles while both run) · Ships: on the next bot releaseWhy
The board's Performance tab reads these names from the exporter today. The exporter's infra collector has failed on every cycle since the bot started serving
/performance/infraper chain, so the infra panels are empty now. The bot builds them itself, but the panels stay empty until the board reads the bot: everyliq_selector is still pinned to the exporter job, and theSourceswitch in #1687 does that.Decisions
/performance/*endpoint serves (HedgeLatencies,InfraReport, and so on). So parity holds by construction, and the goldens feed the exact fixture to both sides.liq-performance-refreshruns every 60 s over the last 24 h, and rebalances every 5th cycle over 30 days, like the exporter. Each collector has a 30 s timeout. A failed or slow collector keeps its last family, and itsliq_collector_last_success_ts_secondsstops.metrics_refresh_duration_seconds{collector}measures each run, with a warn above 10 s.chainlabel per hedged chain. The exporter's unlabelled ones came from a report shape the bot no longer serves. Boardmax(...)queries still work.compare.pyignores the 9 infra names, with the exporter crash as evidence. The dependency series are pinned by a golden against the exporter instead.Proof

Per-chain infra is hand-written (no working exporter baseline).liq_job_queue. Those need a release. On a busy botliq_job_queue{state="done"}may also differ between the two jobs, cause they read the queue up to 60 s apart. I'd add a known difference only once a staging run shows it.Merge conditions
