C4-001 Status

status: done task: modifier_positive_pilot gate: G4 updated: 2026-08-23 America/New_York

C4-001 implements a typed modifierSetEnabled command for the MODIFIER target. The command validates its two-field payload, resolves the modifier before mutation, and uses the shared atomic Main transaction so malformed, stale, wrong-target, and unknown-modifier cases preserve revision and dirty state.

The focused Node test and Chromium-only pilot cover desktop/WASM delta parity, dirty state, negative rollback, undo/redo, save, and reopen. Deterministic receipts and C3-002 regression are recorded under tests/golden/corrective/C4-001/; legacy queue mutation remains forbidden.

All focused, Chromium, deterministic, regression, typecheck, governance, protected-hash, and diff gates exited 0. Handoff manifest: tests/golden/corrective/C4-001/manifest.json. Next corrective task: C4-002.
