# Mint/Burn Flow Changelog
[All versions](https://pharos.watch/methodology/mint-burn-flow-changelog/)
## v4.9 - Deterministic repair loops and adapter provenance disclosures
**Effective:** 2026-03-24
Mint/burn repair and coverage semantics were tightened through historical-first valuation repair, deterministic cleanup backlogs, aligned FTQ classification, and explicit adapter provenance on public coverage metadata.
- Historical price repair now values events from event-day `supply_history` instead of current `price_cache` snapshots
- NULL-price healing and atomic-roundtrip sweeping now use deterministic ordered backlog queries
- The daily digest now shares the same report-card-cache FTQ classification semantics as `/api/mint-burn-flows`
- Per-coin coverage now exposes `adapterKinds`, `startBlockSource`, and `startBlockConfidence` so blanket start-block defaults are visible in the API

## v4.8 - Ethereum coverage wave for long-tail mint/burn tracking
**Effective:** 2026-03-24
Mint/burn flow coverage expanded materially by restoring and adding long-tail Ethereum ERC-20 configs that can be tracked with the standard zero-address Transfer path.
- Added 40 additional Ethereum transfer-based configs for previously uncovered tracked assets
- Extended flow coverage now includes more long-tail fiat, non-USD, commodity, and yield-bearing assets where shared metadata already exposes an Ethereum contract
- Coverage scope increased from 84 contract configs / 83 stablecoin IDs to 124 contract configs / 123 stablecoin IDs while preserving the existing critical-lane set

## v4.7 - Closed-day baseline, fixed aggregate 24h semantics, and coverage disclosures
**Effective:** 2026-03-10
Pressure Shift now compares live 24-hour flows against trailing fully closed daily baselines, aggregate API 24h fields are fixed regardless of chart window, and the product now exposes Ethereum-only scope plus coverage/freshness metadata.
- Pressure Shift baseline now excludes the current UTC day and uses the last 30 fully closed daily buckets
- Aggregate `/api/mint-burn-flows?hours=N` now keeps coin-level 24h fields fixed to the canonical 24h window while only the hourly series respects `hours`
- Aggregate flow API now exposes `scope`, `sync`, `windowHours`, and per-coin `coverage` metadata
- The `/flows` page now labels the feature as Ethereum-only and visually marks partial-history or lagging coverage states
- Flow freshness headers now follow successful sync timestamps instead of latest event timestamps, avoiding false staleness during quiet periods

## v4.6 - Safe-frontier ingestion and counted event-history alignment
**Effective:** 2026-03-09
Mint/burn ingestion now advances only to a shared safe coverage frontier under partial scans, and product event-history surfaces now default to counted economic-flow rows.
- Partial event-definition coverage no longer advances sync state past uncovered log ranges
- Missing block timestamps now cap advancement at the earliest unresolved block instead of silently skipping rows forever
- The event API now exposes `flowType` and supports `scope=counted` for rows that participate in aggregates
- Detail-page flow history now excludes bridge burns, review-required burns, and atomic roundtrips by default
- Unpriced event rows now render native token amounts instead of false dollar values
- `minAmount` filtering is now strictly USD-only when `amountUsd` is available

## v4.5 - Data quality: noise filtering, auto-heal, and activity gating
**Effective:** 2026-03-09
Improves flow data reliability by excluding flash-loan roundtrips from aggregation, auto-healing missing USD prices, and gating pressure shift for low-activity coins.
- Transactions containing both mint and burn for the same token (flash loans, atomic arb) are now flagged as atomic_roundtrip and excluded from all flow aggregates
- Events synced without USD price are now automatically backfilled within 48h by the sync cron
- Coins with less than $50K absolute 24h flow now return NR instead of a potentially misleading pressure shift score
- New observability counters in cron metadata: atomicRoundtripsDetected, nullPricesHealed
Origin: Contemporaneous release record

## v4.4 - Two-signal flow semantics and baseline-aware interpretation
**Effective:** 2026-03-07
Per-coin flow UI now separates raw 24h net flow from baseline-relative pressure shift while preserving the underlying formula.
- Per-coin flow UI now separates raw 24h net flow from baseline-relative pressure shift
- API now exposes canonical `pressureShiftScore` and interpretation fields while retaining `flowIntensity` as a deprecated alias
- Frontend printer and shredder visuals now key off actual net flow direction instead of score sign
- Methodology and product copy now distinguish current direction from pressure-versus-baseline context

## v4.3 - NR gating for no-activity flow windows
**Effective:** 2026-03-04
Coins with no mint/burn activity in the active 24h window now publish NR flow intensity and are excluded from gauge weighting.
- Removed synthetic neutral intensity fallback for sparse no-activity windows
- No-activity windows now return `flowIntensity = null` (NR) instead of `0`
- Bank Run Gauge now excludes those NR windows from the market-cap-weighted composite
- Frontend flow-intensity UI now displays NR explicitly for null values

## v4.2 - Signed zero-baseline flow-intensity semantics
**Effective:** 2026-03-04
Flow Intensity Score and Bank Run Gauge moved from midpoint semantics to canonical signed outputs centered at zero baseline.
- Flow Intensity Score now emits signed values via `clamp(-100, 100, z * 50)`
- Gauge score now uses signed -100 to +100 output with neutral baseline at 0
- Band thresholds were remapped around zero while retaining existing band labels
- Frontend midpoint conversion shim was removed; UI now consumes canonical signed API values directly

## v4.1 - Reliability remediation and controlled backfill recovery
**Effective:** 2026-03-04
Ingestion moved to a reliability-first runtime policy with degraded/error health signaling and operator-grade recovery controls.
- Added run-state rotation plus per-chain quotas so coverage remains balanced under budget pressure
- Added degraded/error escalation from sustained low coverage or repeated API failures
- Introduced authenticated chunked backfill endpoint (`/api/backfill-mint-burn`) reusing ingestion parsing and aggregation

## v4.0 - reUSD deposit amount scale correction
**Effective:** 2026-03-04
Fixed a scale mismatch in reUSD mint decoding that overstated deposit-side mint volume.
- reUSD `Deposited` events now decode with 18 decimals instead of 6
- Removed artificial inflation in reUSD mint flow and related aggregates
- Added regression test validating a known on-chain `Deposited` payload decodes to 10 tokens
