Task(subagent_type="general-purpose", prompt="
You are the Event Completeness Agent. You audit event emission coverage for all state-changing functions.

## Your Inputs
Read:
- {SCRATCHPAD}/setter_list.md (admin setters with event flags)
- {SCRATCHPAD}/emit_list.md (function-to-event mapping)
- {SCRATCHPAD}/event_definitions.md (declared events)
- {SCRATCHPAD}/function_list.md (all functions)
- Source files in scope

## Processing Protocol (MANDATORY)

For each analysis step below, execute in order:
1. **ENUMERATE targets**: List every entity the step applies to (functions, variables, call sites) as a numbered list before analysis begins.
2. **PROCESS exhaustively**: Analyze each numbered entity. Mark each "DONE" or "N/A (reason)" before moving to the next.
3. **COVERAGE GATE**: Count enumerated vs processed. If any entity lacks a marker, process it before proceeding to the next step.

## Your Task

### STEP 1: Build Event Coverage Matrix

For EVERY function that modifies storage state (not just admin setters):

| Function | Contract | Modifies State? | Has Event? | Event Params Match State Changes? | Gap? |
|----------|----------|-----------------|------------|----------------------------------|------|

Sources: setter_list.md (pre-flagged), function_list.md (complete list).
For each function, read the source to verify state changes and event emissions.

### STEP 2: Parameter Accuracy

For each function that DOES emit an event:
- Does the event include ALL changed state variables as parameters?
- Are indexed parameters the ones users/indexers need to filter on?
- Are parameter values emitted BEFORE or AFTER the state change? (should be after)
- Are there emit statements inside conditional branches that could be skipped?
- Does each parameter reflect the CORRECT value? (e.g., output amount not input amount; storage index not loop variable; final state not intermediate value)

### STEP 3: Missing Event Findings

For each gap in the matrix:
- Admin/owner state-changing function without event → finding (severity: Low minimum, Medium if monitoring-critical)
- Public state-changing function without event → finding (severity: Low if view-only impact, Medium if indexer-dependent)
- Event with wrong/missing parameters → finding (severity: Low)
- Event emitted before state change (stale values) → finding (severity: Low)

### STEP 4: Cross-Contract Event Gaps

For multi-contract protocols:
- Does Contract A emit events for state changes that Contract B depends on?
- Are there cross-contract flows where the initiating contract emits but the receiving contract doesn't (or vice versa)?

**Coverage assertion**: Before returning, verify every entity enumerated under each step has been processed. Report enumerated vs analyzed counts in your return message.

## Output Format

Use standard finding format with [EVT-N] IDs.

## Chain Summary (MANDATORY)
| Finding ID | Location | Root Cause (1-line) | Verdict | Severity | Precondition Type | Postcondition Type |

Write to {SCRATCHPAD}/niche_event_findings.md

Return: 'DONE: {N} event coverage gaps found across {M} functions analyzed'
