## Summary

| Category | Total | Implemented | Missing | Coverage |
|----------|-------|-------------|---------|----------|
| **Regular Operations** | 54 | 54 | 0 | 100% |
| **Virtual Operations** | 36 | 36 | 0 | 100% |
| **Plugin API Methods** | 117 | 115 | 2 | 98% |

Includes the HF14 Prediction Markets additions: 23 signed ops + `stakeholder_reward`
and 13 PM virtual ops in the serializer, and 29 `prediction_market_api` read methods.

**Overall Status:** ✅ **FULL COVERAGE**

---

## Prediction Markets (Onix, HF14)

Op-ids are the exact positions in the global `operation` static_variant (65–101),
so binary signing produces the correct varint tag. `stakeholder_reward` (65, virtual)
was added to close the gap before the PM range.

### Signed operations (`viz.broadcast.*`) — auth: active, except `pmDisputeVote` (regular)

| ID | Operation | Builder |
|----|-----------|---------|
| 66 | `pm_oracle_register` | `pmOracleRegister` |
| 67 | `pm_oracle_update` | `pmOracleUpdate` |
| 68 | `pm_create_market` | `pmCreateMarket` |
| 69 | `pm_oracle_accept_market` | `pmOracleAcceptMarket` |
| 70 | `pm_place_bet` | `pmPlaceBet` |
| 71 | `pm_commit_bet` | `pmCommitBet` |
| 72 | `pm_reveal_bet` | `pmRevealBet` |
| 73 | `pm_cancel_bet` | `pmCancelBet` |
| 74 | `pm_add_liquidity` | `pmAddLiquidity` |
| 75 | `pm_withdraw_liquidity` | `pmWithdrawLiquidity` |
| 76 | `pm_resolve_market` | `pmResolveMarket` |
| 77 | `pm_no_contest` | `pmNoContest` |
| 78 | `pm_dispute_create` | `pmDisputeCreate` |
| 79 | `pm_dispute_vote` *(regular)* | `pmDisputeVote` |
| 80 | `pm_dispute_resolve` | `pmDisputeResolve` |
| 81 | `pm_transfer_position` | `pmTransferPosition` |
| 82 | `pm_lazy_deposit` | `pmLazyDeposit` |
| 83 | `pm_lazy_withdraw` | `pmLazyWithdraw` |
| 91 | `pm_leverage_open` | `pmLeverageOpen` |
| 92 | `pm_leverage_close` | `pmLeverageClose` |
| 93 | `pm_leverage_convert` | `pmLeverageConvert` |
| 98 | `pm_dispute_oracle_respond` | `pmDisputeOracleRespond` |
| 99 | `pm_unban` | `pmUnban` |

### Virtual operations (serializer decode only)

`stakeholder_reward` (65), `pm_batch_settle` (84), `pm_commit_forfeit` (85),
`pm_auto_payout` (86), `pm_dispute_finalize` (87), `pm_dispute_auto_close` (88),
`pm_oracle_missed_penalty` (89), `pm_lazy_recall` (90), `pm_leverage_liquidate` (94),
`pm_leverage_resolve` (95), `pm_market_accepted` (96), `pm_payout` (97),
`pm_ban_expired` (100), `pm_market_expired` (101).

### API read methods (`viz.api.*`, plugin `prediction_market_api`)

`getMarket`, `listMarkets`, `listMarketsByOracle`, `listMarketsByCreator`,
`getMarketOutcomes`, `getMarketWeightSums`, `getMarketBets`, `getAccountPositions`,
`getMarketLiquidity`, `getMarketFull`, `getAccountLeveragePositions`,
`getMarketLeveragePositions`, `getCreatorBan`, `getLeverageQuote`,
`getLeverageClosePreview`, `getLeverageConvertPreview`, `getOracle`, `listOracles`,
`getDispute`, `getDisputeVotes`, `getLazyPool`, `getLazyDeposit`, `getLazyAllocations`,
`getMarketLazyAllocation`, `getPmChainProperties`, `getMarketMeta`,
`listMarketsByCategory`, `getMarketCategories`, `getMarketKline`.

### Chain properties & helpers

- `versioned_chain_properties_update` gains a `chain_properties_hf14` variant (tag 5)
  carrying the PM governance parameters (spec §9).
- `viz.formatter.predictionMarketCommitment(marketId, account, side, outcomeIndex, amount, minTokens, salt)`
  — byte-exact SHA-256 commitment for the commit-reveal flow.

### Delta — 2026-07 (oracle-accept window + lazy-pool min-fee)

Two consensus additions surfaced through existing read methods — no new signed op.
The serializer gained one virtual op (`pm_market_expired`, 101, added above).

- `getPmChainProperties` now also returns `pm_oracle_accept_window_sec` (uint32, seconds,
  default 3600) and `pm_lazy_min_liquidity_fee_percent` (uint16, bp, default 200). These are
  pass-through fields — no client code change needed to read them.
- `pm_market_object` now carries a read-only `accept_deadline` (time): `created_time +
  pm_oracle_accept_window_sec` on pending markets, `0` (epoch) on markets active at creation.
  Surfaced pass-through via `getMarket`/`getMarketFull`.
- `pm_market_expired` (vop 101): `oracle`, `creator`, `market_id` (int64),
  `refunded_liquidity` (asset) — emitted when the oracle-accept window lapses and the cron
  refunds the creator's seed liquidity (creation fee forfeited). A rejected market emits no
  vop — detect via `status = -1`.

## Changes Made (03.03.2026)

Added missing API methods to `src/api/methods.js`:

1. **database_api**
   - `get_master_history` - Current naming for master key history
   - `set_block_applied_callback` - WebSocket block subscription

2. **auth_util**
   - `check_authority_signature` - Verify signature against authority

3. **block_info**
   - `get_block_info` - Extended block information
   - `get_blocks_with_info` - Multiple blocks with info

4. **raw_block**
   - `get_raw_block` - Raw serialized block data

**Note:** `private_message` plugin methods (`get_inbox`, `get_outbox`) are deprecated and intentionally not implemented.
