description: >
  Add AC classification rule to CLAUDE.md Agent/Human AC Split section. Risk matrix:
  reversibility x subjectivity x blast radius x external visibility. Default RUBBER-STAMP
  functional tests to Agent ACs with verification commands. Keep sovereignty decisions,
  subjective reviews, irreversible external actions as Human. From T-954 GO.

# T-957: Add AC classification guidance to CLAUDE.md — risk matrix for Human vs Agent ACs (T-954 Phase 1)

## Context

Add AC classification guidance from T-954 research to CLAUDE.md §Agent/Human AC Split. See `docs/reports/T-954-human-ac-classification-reform.md`.

## Acceptance Criteria

### Agent
- [x] CLAUDE.md contains AC classification rule with risk dimensions
- [x] Classification covers: when to use Human AC vs Agent AC
- [x] "When in doubt, Human" default is explicit
- [x] RUBBER-STAMP conversion guidance included
- [x] Verification tier reference (programmatic, TermLink E2E, Playwright)

## Verification

grep -q "AC Classification" CLAUDE.md
grep -q "Reversible" CLAUDE.md
grep -qi "when in doubt" CLAUDE.md
