# Task 8: Add value field to impact log

**Plan**: measure-positive-impact
**Status**: DONE (added annotate-impact.sh for manual value annotation; show-impact.sh displays annotations)
**Depends on**: Task 7 (need the metrics defined first)
**Deliverable**: Updated hook and viewer scripts

## What to do

1. Add optional fields to the impact log JSON schema:
   - `value_summary`: free-text description of value produced.
   - `estimated_reach`: number (people affected).
   - `counterfactual`: enum (none / slower / impossible).
   - `net_assessment`: enum (clearly-positive / probably-positive /
     uncertain / probably-negative / clearly-negative).

2. These fields cannot be filled automatically by the hook — they
   require human or LLM judgment. Options:
   - Add a post-session prompt (via a Stop hook?) that asks for a
     brief value assessment.
   - Accept manual annotation via a helper script.
   - Leave them optional; fill in retrospectively.

3. Update `show-impact.sh` to display value fields when present.

## Done when

- The log schema supports value data alongside cost data.
- `show-impact.sh` displays both.
