| P7 | `perSwapCap` | operational **€10k** / ceiling €50k (amended 2026-09-29; €25k before; re-measure liquidity at the deploy block before raising) |
| P8 | `MAX_ORACLE_AGE` | **52 h** (observed Chainlink EUR/USD weekend gaps up to 48 h; applied to configs 2026-08-26) |
| P9 | Notification confirmation depth | 32 blocks (implemented) |
| P10 | Router pin and routes | SwapRouter02 immutable; routes are a guardian-managed, on-chain validated whitelist (EURe/EURC/USDC, four tiers, ≤ 2 hops); initial route EURe→EURC→USDC at the 5 bps tiers, re-verify at the deploy block (amended 2026-09-15) |
| P10 | Router pin and routes | SwapRouter02 immutable; routes are a guardian-managed, on-chain validated whitelist (EURe/EURC/USDC, four tiers, ≤ 2 hops); initial route **EURe→EURC on the 1 bp tier, EURC→USDC on the 5 bps tier**, re-verify at the deploy block (amended 2026-09-15; re-verified 2026-10-12 at block 26176624: the EURe/EURC liquidity moved from the 5 bps pool, which no longer holds any in range, to the 1 bp pool; the new path quoted 9 to 12 bps below Chainlink for €1k to €25k, and the 5 bps path no longer quoted at all) |
| P11 | Fee adjustability | Guardian `setFeePolicy(target, floor)` within `MAX_FEE_PPM`; raising either value is announced and applies after 24 h, lowering is immediate (amended 2026-09-15) |
| P12 | Reference rate | **Coinbase Exchange EURC-USDC bid/ask midpoint read just before the swap, deferring on a spread above 50 bps** (amended 2026-09-18; from 2026-09-15 a five-minute VWAP over one-minute candles widened to 60 min on no volume), keeper-computed per swap; `MAX_REFERENCE_DEVIATION_BPS` **100** (immutable, to confirm before deploy: must tolerate a weekend Chainlink gap); permissionless path uses Chainlink (2026-09-15). The floor on the net binds first: with `floorPpm` 15 bps and `SLIPPAGE_BPS` 40 bps, a reference more than `SLIPPAGE_BPS − floorPpm` ≈ 25 bps below Chainlink makes every normal fill (fee band or subsidized) revert on chain and defer off chain, so ~25 bps is the working downside margin against a stale round; the 100 bps band is the outlier ceiling for a keeper-supplied value, not the operating tolerance (2026-09-16) |
| P14 | Subsidy ladder | **`MONERIUM_B2B_SUBSIDY_LADDER` = `0:0,360:10,480:20,600:30,720:40,840:50,960:100`** (2026-09-18; keeper policy, tunable from deferral logs); per-chunk clock; the vault's per-swap cap must be at least the ladder's top |
