# STORAGE: BSV Wallet Toolbox API Documentation

The documentation is split into various pages, this page covers the persistent storage of wallet data: transactions, outputs and metadata.

The [WalletStorageManager](#class-walletstoragemanager) class manages a collection of storage providers of which one is the "active" storage
at any one time, and the rest are backups. It manages access to wallet data, pushing incremental updates to backups, and switching the active
to what was previously a backup.

The [StorageClient](#class-storageclient) implements a cloud based storage provider via JSON-RPC. The [StorageServer](#class-storageserver) class
and `@bsv/wallet-infra` package can be used to host such a JSON-RPC server.

The [StorageKnex](#class-storageknex) class implements `Knex` based database storage with explicit support for both MySQL and SQLite.

    api: T;
    constructor(api: T) 
    abstract get id(): number;
    abstract get entityName(): string;
    abstract get entityTable(): string;
    abstract updateApi(): void;
    abstract equals(ei: T, syncMap?: SyncMap): boolean;
    abstract mergeNew(storage: EntityStorage, userId: number, syncMap: SyncMap, trx?: TrxToken): Promise<void>;
    abstract mergeExisting(storage: EntityStorage, since: Date | undefined, ei: T, syncMap: SyncMap, trx?: TrxToken): Promise<boolean>;
    toApi(): T 
}
```

See also: [EntityStorage](./storage.md#type-entitystorage), [SyncMap](./storage.md#interface-syncmap), [TrxToken](./client.md#interface-trxtoken)

###### Method equals

Tests for equality or 'merge' / 'convergent' equality if syncMap is provided.

'convergent' equality must satisfy (A sync B) equals (B sync A)

```ts
abstract equals(ei: T, syncMap?: SyncMap): boolean
```
See also: [SyncMap](./storage.md#interface-syncmap)

###### Method mergeExisting

Perform a 'merge' / 'convergent' equality migration of state
from external `ei` to this existing local EntityUser

```ts
abstract mergeExisting(storage: EntityStorage, since: Date | undefined, ei: T, syncMap: SyncMap, trx?: TrxToken): Promise<boolean>
```
See also: [EntityStorage](./storage.md#type-entitystorage), [SyncMap](./storage.md#interface-syncmap), [TrxToken](./client.md#interface-trxtoken)

Returns

true iff entity state changed and was updated to storage

###### Method mergeNew

Perform a 'merge' / 'convergent' equality migration of state
to this new local entity which was constructed
as a copy of the external object.

```ts
abstract mergeNew(storage: EntityStorage, userId: number, syncMap: SyncMap, trx?: TrxToken): Promise<void>
```
See also: [EntityStorage](./storage.md#type-entitystorage), [SyncMap](./storage.md#interface-syncmap), [TrxToken](./client.md#interface-trxtoken)

Argument Details

+ **userId**
  + local userId

###### Method toApi

An entity may decode properties of the underlying Api object on construction.

The `toApi` method forces an `updateApi` before returning the underlying,
now updated, Api object.

```ts
toApi(): T 
```

Returns

The underlying Api object with any entity decoded properties updated.

###### Method updateApi

On construction, an entity may decode properties of the `api` object,
such as JSON stringified objects.

The `updateApi` method must re-encode the current state of those decoded properties
into the `api` object.

Used by the `toApi` method to return an updated `api` object.

```ts
abstract updateApi(): void
```

static getProofAttemptsLimit = 8
```

###### Property getProofMinutes

How many hours we have to try for a poof

```ts
static getProofMinutes = 60
```

###### Method fromReq

Try to create a new ProvenTx from a ProvenTxReq and GetMerkleProofResultApi

Otherwise it returns undefined and updates req.status to either 'unknown', 'invalid', or 'unconfirmed'

###### Method fromTxid

Given a txid and optionally its rawTx, create a new ProvenTx object.

rawTx is fetched if not provided.

Only succeeds (proven is not undefined) if a proof is confirmed for rawTx,
and hash of rawTx is confirmed to match txid

The returned ProvenTx and ProvenTxReq objects have not been added to the storage database,
this is optional and can be done by the caller if appropriate.

```ts
static async fromTxid(txid: string, services: WalletServices, rawTx?: number[]): Promise<ProvenTxFromTxidResult> 
```
See also: [ProvenTxFromTxidResult](./storage.md#interface-proventxfromtxidresult), [WalletServices](./client.md#interface-walletservices)

###### Method getMerklePath

```ts
getMerklePath(): MerklePath 
```

Returns

desirialized `MerklePath` object, value is cached.

###### Method addHistoryNote

Adds a note to history.
Notes with identical property values to an existing note are ignored.

```ts
addHistoryNote(note: ReqHistoryNote, noDupes?: boolean) 
```
See also: [ReqHistoryNote](./client.md#type-reqhistorynote)

Argument Details

+ **note**
  + Note to add
+ **noDupes**
  + if true, only newest note with same `what` value is retained.

###### Method equals

'convergent' equality must satisfy (A sync B) equals (B sync A)

```ts
override equals(ei: TableProvenTxReq, syncMap?: SyncMap | undefined): boolean 
```
See also: [SyncMap](./storage.md#interface-syncmap), [TableProvenTxReq](./storage.md#interface-tableproventxreq)

###### Method historySince

Returns history to only what followed since date.

```ts
historySince(since: Date): ProvenTxReqHistory 
```
See also: [ProvenTxReqHistory](./storage.md#interface-proventxreqhistory)

###### Method mergeExisting

When merging `ProvenTxReq`, care is taken to avoid short-cirtuiting notification: `status` must not transition to `completed` without
passing through `notifying`. Thus a full convergent merge passes through these sequence steps:
1. Remote storage completes before local storage.
2. The remotely completed req and ProvenTx sync to local storage.
3. The local storage transitions to `notifying`, after merging the remote attempts and history.
4. The local storage notifies, transitioning to `completed`.
5. Having been updated, the local req, but not ProvenTx sync to remote storage, but do not merge because the earlier `completed` wins.
6. Convergent equality is achieved (completing work - history and attempts are equal)

On terminal failure: `doubleSpend` trumps `invalid` as it contains more data.

```ts
override async mergeExisting(storage: EntityStorage, since: Date | undefined, ei: TableProvenTxReq, syncMap: SyncMap, trx?: TrxToken): Promise<boolean> 
```

###### Method updateStorageDynamicProperties

Update storage with changes to non-static properties:
  updated_at
  provenTxId
  status
  history
  notify
  notified
  attempts
  batch

```ts
async updateStorageDynamicProperties(storage: WalletStorageManager | StorageProvider, trx?: TrxToken)

##### Class: StorageClient

`StorageClient` implements the `WalletStorageProvider` interface which allows it to
serve as a BRC-100 wallet's active storage.

Internally, it uses JSON-RPC over HTTPS to make requests of a remote server.
Typically this server uses the `StorageServer` class to implement the service.

The `AuthFetch` component is used to secure and authenticate the requests to the remote server.

`AuthFetch` is initialized with a BRC-100 wallet which establishes the identity of
the party making requests of the remote service.

For details of the API implemented, follow the "See also" link for the `WalletStorageProvider` interface.

Must be called prior to making use of storage.
Retreives `TableSettings` from remote storage provider.

```ts
async makeAvailable(): Promise<TableSettings> 
```
See also: [TableSettings](./storage.md#interface-tablesettings)

Returns

remote storage `TableSettings`

###### Method migrate

async migrate(storageName: string, storageIdentityKey: string): Promise<string> 
```

Returns

current schema migration identifier

Argument Details

+ **storageName**
  + Unique human readable name for remote storage if it does not yet exist.
+ **storageIdentityKey**
  + Unique identity key for remote storage if it does not yet exist.

###### Method processAction

Storage level processing for wallet `createAction` and `signAction`.

Handles remaining storage tasks once a fully signed transaction has been completed. This is common to both `createAction` and `signAction`.

```ts
async processAction(auth: AuthId, args: StorageProcessActionArgs): Promise<StorageProcessActionResults> 
```
See also: [AuthId](./client.md#interface-authid), [StorageProcessActionArgs](./client.md#interface-storageprocessactionargs), [StorageProcessActionResults](./client.md#interface-storageprocessactionresults)

Returns

`StorageProcessActionResults` supporting final wallet processing to yield `createAction` or `signAction` results.

+ **auth**
  + Identifies client by identity key and the storage identity key of their currently active storage.
This must match the `AuthFetch` identity securing the remote conneciton.
+ **args**
  + `StorageProcessActionArgs` convey completed signed transaction to storage.

###### Method processSyncChunk

Process a "chunk" of replication data for the user.

The normal data flow is for the active storage to push backups as a sequence of data chunks to backup storage providers.

```ts
async processSyncChunk(args: RequestSyncChunkArgs, chunk: SyncChunk): Promise<ProcessSyncChunkResult> 
```
See also: [ProcessSyncChunkResult](./client.md#interface-processsyncchunkresult), [RequestSyncChunkArgs](./client.md#interface-requestsyncchunkargs), [SyncChunk](./client.md#interface-syncchunk)

Returns

whether processing is done, counts of inserts and udpates, and related progress tracking properties.

Argument Details

+ **args**
  + a copy of the replication request args that initiated the sequence of data chunks.
+ **chunk**
  + the current data chunk to process.

###### Method relinquishCertificate

Relinquish a certificate.

For storage supporting replication records must be kept of deletions. Therefore certificates are marked as deleted
when relinquished, and no longer returned by `listCertificates`, but are still retained by storage.

```ts
async relinquishCertificate(auth: AuthId, args: RelinquishCertificateArgs): Promise<number> 
```
See also: [AuthId](./client.md#interface-authid)

Argument Details

+ **auth**

This must match the `AuthFetch` identity securing the remote conneciton.
+ **args**
  + original wallet `relinquishCertificate` args.

###### Method relinquishOutput

Relinquish an output.

Relinquishing an output removes the output from whatever basket was tracking it.

```ts
async relinquishOutput(auth: AuthId, args: RelinquishOutputArgs): Promise<number> 
```
See also: [AuthId](./client.md#interface-authid)

Argument Details

+ **auth**
  + Identifies client by identity key and the storage identity key of their currently active storage.
This must match the `AuthFetch` identity securing the remote conneciton.
+ **args**
  + original wallet `relinquishOutput` args.

###### Method setActive

Ensures up-to-date wallet data replication to all configured backup storage providers,
then promotes one of the configured backups to active,
demoting the current active to new backup.

```ts
async setActive(auth: AuthId, newActiveStorageIdentityKey: string): Promise<number> 
```
See also: [AuthId](./client.md#interface-authid)

Argument Details

+ **auth**
  + Identifies client by identity key and the storage identity key of their currently active storage.
This must match the `AuthFetch` identity securing the remote conneciton.
+ **newActiveStorageIdentityKey**
  + which must be a currently configured backup storage provider.

###### Method setServices

Ignored. Remote storage cannot share `Services` with remote clients.

```ts
setServices(v: WalletServices): void 
```
See also: [WalletServices](./client.md#interface-walletservices)

###### Method updateProvenTxReqWithNewProvenTx

Handles the data received when a new transaction proof is found in response to an outstanding request for proof data:

  - Creates a new `TableProvenTx` record.
  - Notifies all user transaction records of the new status.
  - Updates the proof request record to 'completed' status which enables delayed deletion.

```ts
async updateProvenTxReqWithNewProvenTx(args: UpdateProvenTxReqWithNewProvenTxArgs): Promise<UpdateProvenTxReqWithNewProvenTxResult> 
```
See also: [UpdateProvenTxReqWithNewProvenTxArgs](./client.md#interface-updateproventxreqwithnewproventxargs), [UpdateProvenTxReqWithNewProvenTxResult](./client.md#interface-updateproventxreqwithnewproventxresult)

Returns

results of updates

Argument Details

+ **args**
  + proof request and new transaction proof data

###### Method validateEntities

Helper to force uniform behavior across database engines.
Use to process all arrays of records with time stamps retreived from database.

```ts
validateEntities<T extends EntityTimeStamp>(entities: T[], dateFields?: string[]): T[] 
```
See also: [EntityTimeStamp](./client.md#interface-entitytimestamp)

Returns

input `entities` array with contained values validated.

###### Method validateEntity

Helper to force uniform behavior across database engines.
Use to process all individual records with time stamps retreived from database.

```ts
validateEntity<T extends EntityTimeStamp>(entity: T, dateFields?: string[]): T 
```

###### Method allocateChangeInput

Proceeds in three stages:
1. Find an output that exactly funds the transaction (if exactSatoshis is not undefined).
2. Find an output that overfunds by the least amount (targetSatoshis).
3. Find an output that comes as close to funding as possible (targetSatoshis).
4. Return undefined if no output is found.

Outputs must belong to userId and basketId and have spendable true.
Their corresponding transaction must have status of 'completed', 'unproven', or 'sending' (if excludeSending is false).

```ts
async allocateChangeInput(userId: number, basketId: number, targetSatoshis: number, exactSatoshis: number | undefined, excludeSending: boolean, transactionId: number): Promise<TableOutput | undefined> 
```
See also: [TableOutput](./storage.md#interface-tableoutput)

Returns

next funding output to add to transaction or undefined if there are none.

###### Method migrate

This method must be called at least once before any other method accesses the database,
and each time the schema may have updated.

If the database has already been created in this context, `storageName` and `storageIdentityKey`
are ignored.

```ts
async migrate(storageName: string, storageIdentityKey: string): Promise<string> 
```

###### Method readSettings

Called by `makeAvailable` to return storage `TableSettings`.
Since this is the first async method that must be called by all clients,
it is where async initialization occurs.

After initialization, cached settings are returned.

```ts
async readSettings(trx?: TrxToken): Promise<TableSettings> 
```
See also: [TableSettings](./storage.md#interface-tablesettings), [TrxToken](./client.md#interface-trxtoken)

###### Method toDbTrx

Convert the standard optional `TrxToken` parameter into either a direct knex database instance,
or a Knex.Transaction as appropriate.

```ts
toDbTrx(stores: string[], mode: "readonly" | "readwrite", trx?: TrxToken): IDBPTransaction<StorageIdbSchema, string[], "readwrite" | "readonly"> 
```
See also: [StorageIdbSchema](./storage.md#interface-storageidbschema), [TrxToken](./client.md#interface-trxtoken)

###### Method validateEntities

Helper to force uniform behavior across database engines.
Use to process all arrays of records with time stamps retreived from database.

```ts
validateEntities<T extends EntityTimeStamp>(entities: T[], dateFields?: string[], booleanFields?: string[]): T[] 
```
See also: [EntityTimeStamp](./client.md#interface-entitytimestamp)

Returns

input `entities` array with contained values validated.

###### Method validateEntity

Helper to force uniform behavior across database engines.
Use to process all individual records with time stamps or number[] retreived from database.

```ts
validateEntity<T extends EntityTimeStamp>(entity: T, dateFields?: string[], booleanFields?: string[]): T 
```
See also: [EntityTimeStamp](./client.md#interface-entitytimestamp)

###### Method validateEntityForInsert

Helper to force uniform behavior across database engines.
Use to process new entities being inserted into the database.

```ts
async validateEntityForInsert<T extends EntityTimeStamp>(entity: T, trx?: TrxToken, dateFields?: string[], booleanFields?: string[]): Promise<any> 
```
See also: [EntityTimeStamp](./client.md#interface-entitytimestamp), [TrxToken](./client.md#interface-trxtoken)

###### Method validatePartialForUpdate

Helper to force uniform behavior across database engines.
Use to process the update template for entities being updated.

```ts
validatePartialForUpdate<T extends EntityTimeStamp>(update: Partial<T>, dateFields?: string[], booleanFields?: string[]): Partial<T> 
```
See also: [EntityTimeStamp](./client.md#interface-entitytimestamp)

###### Method verifyDB

Following initial database initialization, this method verfies that db is ready for use.

```ts
async verifyDB(storageName?: string, storageIdentityKey?: string): Promise<IDBPDatabase<StorageIdbSchema>> 
```
See also: [StorageIdbSchema](./storage.md#interface-storageidbschema)

Throws

`WERR_INVALID_OPERATION` if the database has not been initialized by a call to `migrate`.

###### Method allocateChangeInput

Finds closest matching available change output to use as input for new transaction.

Transactionally allocate the output such that

```ts
async allocateChangeInput(userId: number, basketId: number, targetSatoshis: number, exactSatoshis: number | undefined, excludeSending: boolean, transactionId: number): Promise<TableOutput | undefined> 
```
See also: [TableOutput](./storage.md#interface-tableoutput)

###### Method countChangeInputs

Counts the outputs for userId in basketId that are spendable: true
AND whose transaction status is one of:
- completed
- unproven
- sending (if excludeSending is false)

###### Method confirmSpendableOutputs

For each spendable output in the 'default' basket of the authenticated user,
verify that the output script, satoshis, vout and txid match that of an output
still in the mempool of at least one service provider.

```ts
async confirmSpendableOutputs(): Promise<{
    invalidSpendableOutputs: TableOutput[];
}> 
```
See also: [TableOutput](./storage.md#interface-tableoutput)

Returns

object with invalidSpendableOutputs array. A good result is an empty array.

###### Method getProvenOrReq

Checks if txid is a known valid ProvenTx and returns it if found.
Next checks if txid is a current ProvenTxReq and returns that if found.
If `newReq` is provided and an existing ProvenTxReq isn't found,
use `newReq` to create a new ProvenTxReq.

This is safe "findOrInsert" operation using retry if unique index constraint
is violated by a race condition insert.

```ts
async getProvenOrReq(txid: string, newReq?: TableProvenTxReq, trx?: TrxToken): Promise<StorageProvenOrReq> 
```
See also: [StorageProvenOrReq](./client.md#interface-storageprovenorreq), [TableProvenTxReq](./storage.md#interface-tableproventxreq), [TrxToken](./client.md#interface-trxtoken)

###### Method getReqsAndBeefToShareWithWorld

Given an array of transaction txids with current ProvenTxReq ready-to-share status,
lookup their ProvenTxReqApi req records.
For the txids with reqs and status still ready to send construct a single merged beef.

```ts
async getReqsAndBeefToShareWithWorld(txids: string[], knownTxids: string[], trx?: TrxToken): Promise<GetReqsAndBeefResult> 
```
See also: [GetReqsAndBeefResult](./storage.md#interface-getreqsandbeefresult), [TrxToken](./client.md#interface-trxtoken)

###### Method getValidBeefForKnownTxid

Pulls data from storage to build a valid beef for a txid.

Optionally merges the data into an existing beef.
Optionally requires a minimum number of proof levels.

```ts
async getValidBeefForKnownTxid(txid: string, mergeToBeef?: Beef, trustSelf?: TrustSelf, knownTxids?: string[], trx?: TrxToken, requiredLevels?: number): Promise<Beef> 
```
See also: [TrxToken](./client.md#interface-trxtoken)

###### Method updateProvenTxReqWithNewProvenTx

Handles storage changes when a valid MerklePath and mined block header are found for a ProvenTxReq txid.

Performs the following storage updates (typically):
1. Lookup the exising `ProvenTxReq` record for its rawTx
2. Insert a new ProvenTx record using properties from `args` and rawTx, yielding a new provenTxId
3. Update ProvenTxReq record with status 'completed' and new provenTxId value (and history of status changed)
4. Unpack notify transactionIds from req and update each transaction's status to 'completed', provenTxId value.
5. Update ProvenTxReq history again to record that transactions have been notified.
6. Return results...

Alterations of "typically" to handle:

```ts
async updateProvenTxReqWithNewProvenTx(args: UpdateProvenTxReqWithNewProvenTxArgs): Promise<UpdateProvenTxReqWithNewProvenTxResult> 
```
See also: [UpdateProvenTxReqWithNewProvenTxArgs](./client.md#interface-updateproventxreqwithnewproventxargs), [UpdateProvenTxReqWithNewProvenTxResult](./client.md#interface-updateproventxreqwithnewproventxresult)

###### Method updateTransactionStatus

For all `status` values besides 'failed', just updates the transaction records status property.

For 'status' of 'failed', attempts to make outputs previously allocated as inputs to this transaction usable again.

```ts
async updateTransactionStatus(status: TransactionStatus, transactionId?: number, userId?: number, reference?: string, trx?: TrxToken): Promise<void> 
```

##### Class: StorageReader

The `StorageReader` abstract class is the base of the concrete wallet storage provider classes.

It is the minimal interface required to read all wallet state records and is the base class for sync readers.

The next class in the heirarchy is the `StorageReaderWriter` which supports sync readers and writers.

The last class in the heirarchy is the `Storage` class which supports all active wallet operations.

The ability to construct a properly configured instance of this class implies authentication.
As such there are no user specific authenticated access checks implied in the implementation of any of these methods.

```ts
export abstract class StorageReader implements sdk.WalletStorageSyncReader {
    chain: sdk.Chain;

##### Class: StorageSyncReader

The `StorageSyncReader` non-abstract class must be used when authentication checking access to the methods of a `StorageBaseReader` is required.

Constructed from an `auth` object that must minimally include the authenticated user's identityKey,
and the `StorageBaseReader` to be protected.

    constructor(public auth: sdk.AuthId, public storage: StorageReader) 
    async makeAvailable(): Promise<TableSettings> 
    destroy(): Promise<void>

##### Class: WalletStorageManager

The `WalletStorageManager` class delivers authentication checking storage access to the wallet.

If manages multiple `StorageBase` derived storage services: one actice, the rest as backups.

Of the storage services, one is 'active' at any one time.
On startup, and whenever triggered by the wallet, `WalletStorageManager` runs a syncrhonization sequence:

1. While synchronizing, all other access to storage is blocked waiting.
2. The active service is confirmed, potentially triggering a resolution process if there is disagreement.
3. Changes are pushed from the active storage service to each inactive, backup service.

Some storage services do not support multiple writers. `WalletStorageManager` manages wait-blocking write requests
for these services.

```ts
export class WalletStorageManager implements sdk.WalletStorage {
    _stores: ManagedStorage[] = [];
    _isAvailable: boolean = false;
    _active?: ManagedStorage;
    _backups?: ManagedStorage[];

```

###### Property _services

Configured services if any. If valid, shared with stores (which may ignore it).

```ts
_services?: sdk.WalletServices
```
See also: [WalletServices](./client.md#interface-walletservices)

```

Returns

true if at least one WalletStorageProvider has been added.

###### Method isActiveStorageProvider

```ts
isActiveStorageProvider(): boolean 
```

Returns

true if the active `WalletStorageProvider` also implements `StorageProvider`

###### Method makeAvailable

This async function must be called after construction and before
any other async function can proceed.

Runs through `_stores` validating all properties and partitioning across `_active`, `_backups`, `_conflictingActives`.

```ts
async makeAvailable(): Promise<TableSettings> 
```
See also: [TableSettings](./storage.md#interface-tablesettings)

Returns

from the active storage.

Throws

WERR_INVALID_PARAMETER if canMakeAvailable returns false.

###### Method reproveHeader

For each proven_txs record currently sourcing its transaction merkle proof from the given deactivated header,
attempt to reprove the transaction against the current chain,
updating the proven_txs record if a new valid proof is found.

```ts
async reproveHeader(deactivatedHash: string): Promise<sdk.ReproveHeaderResult> 
```
See also: [ReproveHeaderResult](./client.md#interface-reproveheaderresult)

Argument Details

+ **deactivatedHash**
  + An orphaned header than may have served as a proof source for proven_txs records.

###### Method reproveProven

Attempt to reprove the transaction against the current chain,
If a new valid proof is found and noUpdate is not true,
update the proven_txs record with new block and merkle proof data.
If noUpdate is true, the update to be applied is available in the returned result.

```ts
async reproveProven(ptx: TableProvenTx, noUpdate?: boolean): Promise<sdk.ReproveProvenResult>

+ **sync**
  + the function to run with sync access lock
+ **activeSync**
  + from chained sync functions, active storage already held under sync access lock.

###### Method setActive

Updates backups and switches to new active storage provider from among current backup providers.

Also resolves conflicting actives.

```ts
async setActive(storageIdentityKey: string, progLog?: (s: string) => string): Promise<string> 
```

Argument Details

+ **storageIdentityKey**
  + of current backup storage provider that is to become the new active provider.

###### Method verifyAndRepairBeef

Extends the Beef `verify` function to handle BUMPs that have become invalid due to a chain reorg,
and originated from proven_txs records tracked by this storage.

This method is optimized for making sure outgoing beefs are valid before sharing them externally.
In particular, it only "repairs" proofs previously tracked by this storage.

Any merkle root that fails `isValidRootForHeight` triggers a reprove attempt for that block header.
This results in proven_txs with invalid proofs being updated with new valid proofs where possible.

```ts
async verifyAndRepairBeef(beef: Beef, allowTxidOnly?: boolean): Promise<VerifyAndRepairBeefResult> 
```
See also: [VerifyAndRepairBeefResult](./storage.md#interface-verifyandrepairbeefresult)

Returns

VerifyAndRepairBeefResult, in particular `verifiedBeef` is valid only verify and repair succeeded fully.

##### Function: getBeefForTransaction

Creates a `Beef` to support the validity of a transaction identified by its `txid`.

`storage` is used to retrieve proven transactions and their merkle paths,
or proven_tx_req record with beef of external inputs (internal inputs meged by recursion).
Otherwise external services are used.

`options.maxRecursionDepth` can be set to prevent overly deep chained dependencies. Will throw ERR_EXTSVS_ENVELOPE_DEPTH if exceeded.

If `trustSelf` is true, a partial `Beef` will be returned where transactions known by `storage` to
be valid by verified proof are represented solely by 'txid'.

If `knownTxids` is defined, any 'txid' required by the `Beef` that appears in the array is represented solely as a 'known' txid.

```ts
export async function getBeefForTransaction(storage: StorageProvider, txid: string, options: StorageGetBeefOptions): Promise<Beef> 
```

See also: [StorageGetBeefOptions](./client.md#interface-storagegetbeefoptions), [StorageProvider](./storage.md#class-storageprovider)

Argument Details

+ **storage**
  + the chain on which txid exists.
+ **txid**
  + the transaction hash for which an envelope is requested.

---
##### Function: internalizeAction

Internalize Action allows a wallet to take ownership of outputs in a pre-existing transaction.
The transaction may, or may not already be known to both the storage and user.

Two types of outputs are handled: "wallet payments" and "basket insertions".

A "basket insertion" output is considered a custom output and has no effect on the wallet's "balance".

A "wallet payment" adds an outputs value to the wallet's change "balance". These outputs are assigned to the "default" basket.

Processing starts with simple validation and then checks for a pre-existing transaction.
If the transaction is already known to the user, then the outputs are reviewed against the existing outputs treatment,
and merge rules are added to the arguments passed to the storage layer.
The existing transaction must be in the 'unproven' or 'completed' status. Any other status is an error.

When the transaction already exists, the description is updated. The isOutgoing sense is not changed.

"basket insertion" Merge Rules:
1. The "default" basket may not be specified as the insertion basket.
2. A change output in the "default" basket may not be target of an insertion into a different basket.
3. These baskets do not affect the wallet's balance and are typed "custom".

"wallet payment" Merge Rules:
1. Targetting an existing change "default" basket output results in a no-op. No error. No alterations made.
2. Targetting a previously "custom" non-change output converts it into a change output. This alters the transaction's `satoshis`, and the wallet balance.

##### Type: PostReqsToNetworkDetailsStatus

Indicates status of a new Action following a `createAction` or `signAction` in immediate mode:
When `acceptDelayedBroadcast` is falses.

'success': The action has been broadcast and accepted by the bitcoin processing network.
'doulbeSpend': The action has been confirmed to double spend one or more inputs, and by the "first-seen-rule" is the loosing transaction.
'invalidTx': The action was rejected by the processing network as an invalid bitcoin transaction.
'serviceError': The broadcast services are currently unable to reach the bitcoin network. The action is now queued for delayed retries.

'invalid': The action was in an invalid state for processing, this status should never be seen by user code.
'unknown': An internal processing error has occured, this status should never be seen by user code.

```ts
export type PostReqsToNetworkDetailsStatus = "success" | "doubleSpend" | "unknown" | "invalid" | "serviceError" | "invalidTx"
```
