Shared decision contract
Verified gates: every school day must cover 16:00–18:30; transport and named pickup must be verified; out-of-pocket spending ≤2,400/month; both adults consent to contracts/work changes; Child 13 is never assigned responsibility for Child 8. Any option failing a gate is unavailable regardless of score.
Criteria use 1/3/5 anchors: predictability—frequent improvisation / conditional weekly plan / stable named coverage; child fit—conflicts with stated needs / mixed and adjustable / supports both children's stated needs; adult load—unowned or concentrated / explicit but uneven / owned with backup; grandparent burden—conflicts with stated boundary / feasible with conditions / low burden; cost—over ceiling / within ceiling with uncertainty / verified comfortably within; reversibility—high exit cost / conditional / easy exit. Unknowns remain blank. Equal weights are provisional and do not average away gates.
Option assessment: O1 cannot yet pass because places, terms, transport, pickup, and coverage for non-program days are unknown. Quoted cost passes the ceiling provisionally. It may support Child 8's friend preference but Tuesday could conflict with Child 13's music depending on days. O2 is over the stated ceiling if income effect is treated as household cost and employer approval is unknown; it also risks concentrating load. O3 has potential budget fit but transport, darkness timing, the grandparent's withdrawal fallback, program day, and remaining coverage are unresolved. O4 fails predictability and has no verified full coverage. No option is currently decision-ready.
Required evidence by 7 September: program places, days, pickup rules, cancellation and four-week trial terms; employer decision and exact hours/income effect; verified routes and sunset-compatible grandparent transport; a full Monday–Friday owner/backup grid for O1 and O3; Adult B coordination tasks made explicit.
A trial recommendation is conditional, not a choice: if O1 offers a no-long-contract four-week trial, verified routes, named pickups, complete coverage, and suitable days within 2,400, test it for four weeks. Otherwise compare a fully specified O3; do not assume grandparent availability. Success: all pickups covered, children report workable experience, music remains possible, adult coordination stays within agreed ownership, and no boundary breach. Stop for unsafe/uncovered transport, unwanted long commitment, grandparent withdrawal without backup, or either adult refusing the arrangement. Record each person's view; silence is not consensus.
