v0.3.2

Version aligned with the alpenglow ag-v0.3.2 tag this release was
validated against.

Added

• Stage 1 canonical-skip classifier (aggregator::classify_skips):
  walks parent pointers from observed Finalized slots, assigns
  every voted_skip slot to DirectFinalize / Ancestry /
  Indeterminate. The headline operator-facing metric
  canonical-skip % is derived from this classification.
• EventKind::TriggeringParentReady parser variant for the
  event_handler::add_missing_parent_ready log line; counter on
  OverallStats (intentionally unsurfaced, reserved for future
  per-window analysis).
• Standstill range tracking: OverallStats.standstill_ranges built
  from StandstillExtending / StandstillEnded events, including
  EOS-orphan close. New timeout_crashed_leaders_outside_standstill
  counter computed in analyze filters TCLs that fired inside a
  standstill window (where the per-slot timeout is stretched and the
  leader did not actually misbehave).
• SlotViewRow.consensus_inverted flag rendered as ↶ in the
  Slots-tab consensus column for rows where the cluster's
  Finalized cert arrived before the local node's Block event
  (cluster outran local replay). Plain - is now reserved for
  genuinely missing data.
• theme::TRUE_FB_ELEVATED_PCT threshold constant.
• ProduceWindow corruption guards (oversized span > 16,
  inverted range end < start), counted in
  OverallStats.malformed_produce_window.
• MirrorSparkline widget on the time-series tab for the paired
  vote-skip / canonical-skip mirror chart (one rises from the
  bottom, the other hangs from the top, shared x-axis).

Changed

• Slot status labels: SKIP renamed to VSKIP (we Voted skip,
  no canonical evidence). CSKIP unchanged. The V / C prefix
  convention makes both labels self-describing — both refer to
  our vote; the prefix indicates whether canonical evidence
  exists.
• Slots-tab filter hotkeys rotated:
  [v] = VSKIP only, [c] = CSKIP only,
  [s] = SLOW, [x] = clear all filters,
  [b] freed. SlotFilters::vskip_only replaces skipped_only
  with narrowed semantic; the skip-family pair (vskip_only,
  canonical_skip_only) now uses OR semantics — pressing both
  shows the union.
• Slots-tab consensus column now distinguishes three states:
  positive value in ms (normal), ↶ (cluster outran local
  replay), - (missing data).
• Slots-tab Latency bands reference panel adds a consensus
  threshold row (≤ 300 ms · 300–600 ms · > 600 ms).
• Slots-tab KPI strip: leader-slot share metric moved from the
  buried right-panel footer onto slot stats line 2 next to the
  lifecycle percentiles. p95 value is now health-coloured at the
  KPI site, replacing the previous footer row.
• Slots-tab legend: static column-value reference (status, vote,
  consensus glyph) moved to the bottom of the panel below the
  [x] clear all filters separator. The filter section above is
  now exclusively interactive toggles.
• Slots-panel title shortened: drops the redundant total in
  slots (N total | cursor M / N) → slots (cursor M / N). The
  filtered variant retains M of N.
• vote & cert totals widget on Overview rewritten as three
  horizontal columns (votes / certs / finalized) instead
  of stacked text. Headings styled in title_style.
• Overview headline-health fast-finalize row dropped the
  fast NN.NN% / slow NN.NN% breakdown (the numbers now live
  in the vote & cert totals finalized column). Verdict mark
  and text retained.
• Alerts-tab detail block + list block + Overview alerts
  widget gain Padding::new(...) for breathing room from the
  block border.
• Alerts-tab detail widget adds explicit blank lines between
  the last and span rows and between the first sample
  label and the sample body.
• Leader-timeouts trend chart uses a packing-search algorithm
  to pick (bar_width, bar_count) that fills the panel width.
  bar_width capped at 6 columns so very wide terminals do not
  collapse the chart to a handful of thick bars.
• Header crashed leaders metric on Overview adopts the
  standstill-aware count when standstill ranges exist (raw count
  appears on a continuation line); when no standstill ranges
  exist, the single-line display is unchanged.
• Canonical-skip lower-bound marker (≥) now applied on the
  Slots-tab KPI strip when indeterminate_skips > 0, matching
  the header, overview, windows, and --text runner surfaces.
• stake share label removed. Renamed leader-slot share
  (window-relative, not on-chain stake — the previous label
  overstated what the tool measures).
• Severity::from_us thresholds (1.5 s / 3.0 s) documented as
  provisional pending empirical calibration across multi-day
  log archives.
• True-FB cutoff 0.5% consolidated into
  theme::TRUE_FB_ELEVATED_PCT and consumed at both render
  sites (was a duplicated literal).
• True-FB percentage formatted as {:.2}% (was {:.3}% — no
  false precision on an integer-count ratio).

Fixed

• Slots-tab canonical-skip percentage was missing the ≥
  lower-bound marker even when indeterminate skips existed.
  Same number now reads consistently across all surfaces.
• Seven previously-undocumented OverallStats fields received
  reserved-for-future docstrings explicitly marking them as
  intentionally unsurfaced (matching the existing
  parent_ready_recoveries precedent): malformed_produce_window,
  standstill_extending_events, standstill_ended_events,
  no_epoch_info_for_slot, updating_epoch_metadata,
  evicting_epoch_metadata, invalid_cluster_slots_update.

Internal

• Test count: 187 → 201 across the workspace.
• aggregator/tests.rs (989 LOC) split into 6 sub-modules under
  aggregator/tests/ (ingest, standstill, classify_skips,
  log_patterns, produce_window, analyze_alerts).
• tui/app.rs inline mod tests (309 LOC) extracted to
  tui/app_tests.rs via #[path] declaration; production
  module drops to 753 LOC, under the 800 strong-warn threshold.
• OverallStats unique-slot count docstrings clarified —
  finalized_slot_count + skipped_slot_count + pending_slot_count
  is overlap, not partition (a canonical-skip slot is counted in
  both finalized_slot_count and skipped_slot_count).
• rustfmt + strict clippy fixes for the workspace:
  explicit_iter_loop, doc_overindented_list_items,
  type_complexity, items_after_statements, derivable_impls.
