+# Proven Periods Bitmap - Technical Reference
+
+This document explains the bitmap storage system used for tracking proving periods in the FilecoinWarmStorageService contract.
+
+## Overview
+
+The contract uses an optimized bitmap storage mechanism to efficiently track which proving periods have been successfully proven. Instead of storing one boolean per period (which would consume one storage slot per period), the contract packs 256 periods into a single `uint256` storage slot.
+
+## Storage Structure
+
+```solidity
+mapping(uint256 dataSetId => mapping(uint256 bucketId => uint256)) private provenPeriods;
+```
+
+- **Outer mapping**: Maps each dataset ID to its own proving history
+- **Inner mapping**: Maps bucket IDs to uint256 values (each holds 256 bits)
+- **Each bit**: Represents whether a specific period was proven (1) or faulted (0)
+
+## Bit Manipulation
+
+### Setting a Period as Proven
+
+```solidity
+provenPeriods[dataSetId][periodId >> 8] |= (1 << (periodId & 255));
+```
+
+**Breaking this down:**
+
+1. **`periodId >> 8`** - Right shift by 8 bits (divide by 256)
+   - This calculates which bucket to use
+   - Example: Period 1000 → Bucket 3 (1000 ÷ 256 = 3)
+
+2. **`periodId & 255`** - Bitwise AND with 255 (modulo 256)
+   - This calculates which bit within the bucket
+   - Example: Period 1000 → Bit 232 (1000 % 256 = 232)
+
+3. **`1 << (periodId & 255)`** - Left shift 1 by the bit position
+   - Creates a bitmask with only that bit set
+   - Example: For bit 232 → `0x...0100000000000000000000000000000000000000000000000000000000000000`
+
+4. **`|=`** - Bitwise OR assignment
+   - Sets the bit to 1 without affecting other bits
+   - Preserves all existing bits in the bucket
+
+### Checking if a Period is Proven
+
+```solidity
+function _isPeriodProven(uint256 dataSetId, uint256 periodId) private view returns (bool) {
+    return provenPeriods[dataSetId][periodId >> 8] & (1 << (periodId & 255)) != 0;
+}
+```
+
+**Breaking this down:**
+
+1. **Get the bucket**: `provenPeriods[dataSetId][periodId >> 8]`
+2. **Create bitmask**: `1 << (periodId & 255)`
+3. **Bitwise AND**: Checks if the specific bit is set
+4. **Compare to 0**: Returns true if bit is set, false otherwise
+
+## Examples
+
+### Example 1: Period 0
+
+```
+periodId = 0
+
+Bucket calculation: 0 >> 8 = 0
+Bit position: 0 & 255 = 0
+Bitmask: 1 << 0 = 0x0000...0001
+
+Storage location: provenPeriods[dataSetId][0]
+Bit position: 0 (rightmost bit)
+```
+
+### Example 2: Period 255
+
+```
+periodId = 255
+
+Bucket calculation: 255 >> 8 = 0
+Bit position: 255 & 255 = 255
+Bitmask: 1 << 255 = 0x8000...0000
+
+Storage location: provenPeriods[dataSetId][0]
+Bit position: 255 (leftmost bit)
+```
+
+### Example 3: Period 256
+
+```
+periodId = 256
+
+Bucket calculation: 256 >> 8 = 1
+Bit position: 256 & 255 = 0
+Bitmask: 1 << 0 = 0x0000...0001
+
+Storage location: provenPeriods[dataSetId][1]
+Bit position: 0 (rightmost bit of second bucket)
+```
+
+### Example 4: Period 1000
+
+```
+periodId = 1000
+
+Bucket calculation: 1000 >> 8 = 3
+Bit position: 1000 & 255 = 232
+Bitmask: 1 << 232 = 0x0100000000000000000000000000000000000000000000000000000000000000
+
+Storage location: provenPeriods[dataSetId][3]
+Bit position: 232
+```

+### Single uint256 Bucket Example
+
+```
+uint256 value = provenPeriods[dataSetId][0]
+
+Bit layout (256 bits total):
+Position: 255 254 253 ... 003 002 001 000
+Value:      1   0   1  ...  1   0   1   1
+Meaning:    ✓   ✗   ✓  ...  ✓   ✗   ✓   ✓
+
+✓ = Period proven (bit = 1)
+✗ = Period faulted (bit = 0)
+```
+
+## Gas Efficiency
+
+### Without Bitmap (naive approach)
+```solidity
+mapping(uint256 dataSetId => mapping(uint256 periodId => bool)) private provenPeriods;
+```
+- **Storage**: 1 slot per period
+- **Cost**: ~20,000 gas per period to set from 0 to 1
+
+### With Bitmap (optimized)
+```solidity
+mapping(uint256 dataSetId => mapping(uint256 bucketId => uint256)) private provenPeriods;
+```
+- **Storage**: 1 slot per 256 periods
+- **Cost**:
+  - First bit in bucket: ~20,000 gas (cold storage)
+  - Additional bits in same bucket: ~5,000 gas (warm storage)
+- **Space savings**: 256× reduction in storage slots
+
+## Querying via RPC
+
+### Direct Storage Query (Advanced)
+
+To read the raw bitmap directly from storage:
+
+```bash
+# Calculate storage slot for provenPeriods[dataSetId][bucketId]
+# This requires knowing the storage layout
+
+cast storage <CONTRACT_ADDRESS> <STORAGE_SLOT> --rpc-url <RPC_URL>
+```
+
+### View Function Query (Recommended)
+
+```bash
+# Check if a specific period is proven
+cast call <CONTRACT_ADDRESS> \
+  "provenPeriods(uint256,uint256)" \
+  <dataSetId> <periodId> \
+  --rpc-url <RPC_URL>
+```
+
+Returns:
+- `0x0000...0001` if period is proven
+- `0x0000...0000` if period faulted
+
+## Decoding Bitmap in Scripts
+
+### Pseudocode
+
+```python
+def is_period_proven(bitmap_value, period_id):
+    """Check if a specific period is proven given the bucket bitmap."""
+    bit_position = period_id & 255  # period_id % 256
+    bitmask = 1 << bit_position
+    return (bitmap_value & bitmask) != 0
+
+def get_all_proven_periods_in_bucket(bitmap_value, bucket_id):
+    """Extract all proven periods from a single bucket."""
+    proven_periods = []
+    base_period = bucket_id * 256
+
+    for bit_pos in range(256):
+        if bitmap_value & (1 << bit_pos):
+            proven_periods.append(base_period + bit_pos)
+
+    return proven_periods
+```
+
+### Shell Script Example
+
+```bash
+# Query bucket 0 (periods 0-255)
+bucket_value=$(cast call $CONTRACT "provenPeriods(uint256,uint256)" $DATASET_ID 0 --rpc-url $RPC)
+
+# Check specific period (e.g., period 100)
+period_id=100
+bit_position=$((period_id & 255))  # 100 % 256 = 100
+bitmask=$((1 << bit_position))
+
+# Check if period is proven
+if (( (bucket_value & bitmask) != 0 )); then
+    echo "Period $period_id is PROVEN"
+else
+    echo "Period $period_id is FAULTED"
+fi
+```
+
+## Related Contract Code
+
+### File: `service_contracts/src/FilecoinWarmStorageService.sol`
+
+**Setting proven period (line 933):**
+```solidity
+provenPeriods[dataSetId][currentPeriod >> 8] |= (1 << (currentPeriod & 255));
+```
+
+**Checking proven period (line 1621):**
+```solidity
+function _isPeriodProven(uint256 dataSetId, uint256 periodId) private view returns (bool) {
+    return provenPeriods[dataSetId][periodId >> 8] & (1 << (periodId & 255)) != 0;
+}
+```
+
+**Public view function (StateView.sol line 142):**
+```solidity
+function provenPeriods(uint256 dataSetId, uint256 periodId) public view returns (bool) {
+    return FilecoinWarmStorageServiceStateLibrary.provenPeriods(service, dataSetId, periodId);
+}
+```
+
+## Common Pitfalls
+
+### ❌ Wrong: Direct boolean storage
+```solidity
+mapping(uint256 => mapping(uint256 => bool)) provenPeriods;
+```
+- Uses 1 storage slot per period
+- Expensive for long-term storage
+
+### ❌ Wrong: Incorrect bit calculation
+```solidity
+// Don't use division and modulo operators
+uint256 bucket = periodId / 256;      // More expensive than >>
+uint256 bitPos = periodId % 256;      // More expensive than &
+```
+
+### ✅ Correct: Bitmap with bitwise operations
+```solidity
+mapping(uint256 => mapping(uint256 => uint256)) provenPeriods;
+provenPeriods[dataSetId][periodId >> 8] |= (1 << (periodId & 255));
+```
+- Uses 1 storage slot per 256 periods
+- Efficient bitwise operations
+- Scales to thousands of periods
+
+## Performance Comparison
+
+| Approach | Storage per 1000 periods | Gas for setting 1000 periods |
+|----------|--------------------------|------------------------------|
+| Individual bools | 1000 slots | ~20,000,000 gas |
+| Bitmap (optimized) | 4 slots | ~100,000 gas |
+| **Savings** | **99.6% less** | **99.5% less** |

+
+## Interpreting the Output
+
+### Status Indicators
+
+- **✓ PROVEN** (Green) - The provider successfully submitted proof for this period
+- **✗ FAULTED** (Red) - The deadline passed without a valid proof being submitted
+- **○ Not yet due** (White) - The deadline for this period has not yet arrived
+
+### Key Metrics
+
+1. **Current Block** - The latest block on the chain
+2. **Activation Epoch** - When proving started for this dataset
+3. **Current Deadline** - The block number of the next proving deadline
+4. **Max Proving Period** - How many blocks between each proof requirement
+5. **Challenge Window** - How many blocks before the deadline proofs can be submitted
+
+### Understanding Deadlines
+
+- If `Current Block < Challenge Window Start`: Too early to submit proof
+- If `Challenge Window Start <= Current Block <= Deadline`: Can submit proof now
+- If `Current Block > Deadline`: Deadline missed - provider is late!
+
+### Fault Rate
+
+The fault rate is calculated as:
+```
+Fault Rate = (Faulted Periods / Total Checked Periods) × 100%
+```
+
+A fault rate of 0% means perfect proving performance. Higher fault rates indicate reliability issues.

+# Filecoin Services Scripts
+
+This directory contains utility scripts for interacting with Filecoin Warm Storage Service contracts.
+
+## Fault Status Query Scripts
+
+Two equivalent scripts are provided for querying fault status:
+- `query-fault-status.fish` - Fish shell version
+- `query-fault-status.sh` - Bash version (more widely compatible)
+
+Both scripts provide the same functionality to query and analyze the fault history of a dataset in the Filecoin Warm Storage Service.
+
+### Features
+
+- Queries the proving period fault bitmap from the contract
+- Reconstructs complete fault history for all proving periods
+- Calculates whether the provider is currently up to date with proving
+- Determines how late the provider is if they missed deadlines
+- Generates a detailed, color-coded report
+
+### Prerequisites
+
+- [Foundry](https://book.getfoundry.sh/getting-started/installation) (forge/cast) installed
+- Either Bash (usually pre-installed) or [Fish shell](https://fishshell.com/)
+- Access to a Filecoin RPC endpoint
+
+### Installation
+
+```bash
+# Install Foundry
+curl -L https://foundry.paradigm.xyz | bash

+```
+
+### Output
+
+The script generates a comprehensive report including:
+
+1. **Configuration Summary**
+   - Dataset ID
+   - Contract address
+   - Current block number
+   - Proving configuration (activation epoch, deadline, period length, challenge window)
+
+2. **Proving Period Analysis**
+   - Current proving period
+   - Challenge window status
+   - Whether deadline was missed and by how many blocks
+
+3. **Fault History Table**
+   - Period-by-period breakdown
+   - Deadline for each period
+   - Status (Proven/Faulted/Pending)
+
+4. **Summary Statistics**
+   - Total periods checked
+   - Number of proven periods
+   - Number of faulted periods
+   - Fault rate percentage
+
+### How It Works
+
+#### Bitmap Decoding
+
+The script queries the `provenPeriods` mapping which uses an optimized bitmap storage system:
+
+- Each `uint256` stores 256 periods as individual bits
+- `periodId >> 8` determines which storage bucket
+- `periodId & 255` determines which bit within the bucket
+- Bit value 1 = period was proven successfully
+- Bit value 0 = period faulted (proof not submitted)
+
+#### Contract Queries
+
+The script makes the following RPC calls using `cast call`:
+
+1. `provingActivationEpoch(uint256)` - When proving started
+2. `provingDeadline(uint256)` - Current deadline block
+3. `getMaxProvingPeriod()` - Length of each proving period
+4. `challengeWindow()` - Size of the challenge window
+5. `provenPeriods(uint256,uint256)` - Check if specific period was proven
+
+#### Fault Detection
+
+For each proving period:
+
+1. Calculate the deadline: `activationEpoch + (periodId + 1) * maxProvingPeriod`
+2. Query if the period was proven using `provenPeriods(dataSetId, periodId)`
+3. If deadline has passed and period not proven → **FAULT**
+4. If deadline has passed and period proven → **SUCCESS**
+5. If deadline not yet reached → **PENDING**
+
+### Technical Details
+
+#### Proving Period Calculation
+
+```
+currentPeriod = (currentBlock - activationEpoch) / maxProvingPeriod
+```
+
+#### Challenge Window
+
+The challenge window is the time period during which a provider can submit their proof:
+
+```
+challengeWindowStart = deadline - challengeWindowSize
+```
+
+Proofs can only be submitted when:
+```
+challengeWindowStart <= currentBlock <= deadline
+```
+
+#### Periods Missed
+
+If the current block is past the deadline:
+
+```
+blocksOverdue = currentBlock - deadline
+periodsMissed = floor(blocksOverdue / maxProvingPeriod)
+```
+
+### Troubleshooting
+
+#### "cast: command not found"
+
+Install Foundry:
+```bash
+curl -L https://foundry.paradigm.xyz | bash
+foundryup
+```
+
+#### RPC connection errors
+
+- Ensure the RPC URL is correct and accessible
+- Try using a different RPC endpoint
+- Check if you need authentication/API keys
+
+#### "Failed to query contract state"
+
+- Verify the contract address is correct
+- Ensure the dataset ID exists
+- Check that the RPC endpoint is synced
+
+### Contract Addresses
