With several obligation solutions, the planner ran the whole preference
chain on candidate solutions as previews: every solution after a
complete enumeration, or the eight best-ranked after a truncated window
search. It now orders all solutions by the existing pre-preference
ranking (active objectives, then tie-breaks, of each obligation-only
plan; equal ranks keep enumeration order) and runs the preference
stages once, on the first. If that run ends with earned leave available
only after its final merged time-off period, the stages restart on the
next solution, so a request that planned before never becomes a
conflict.
The loaded year drops from 43 to 5.5 seconds and typed obligations from
3.3 to 0.1 seconds, with byte-identical benchmark plans. Over the 5,000
seeded requests, 23 plans become worse (9 on a real objective) and 1
better; over 50 loaded-year-sized requests, 4 become worse on a real
objective. ADR 0010 records the decision; docs/benchmark/issue-302.md
records the comparison and the opt-in runner that reproduces it.
The frozen-engine check fails until the frozen engine is rebuilt from
this commit in the next one.
Part of #302.

Run the unchanged benchmark as a separate advisory job while #78 is open.
Keep functional coverage and other checks required, and retain the 2 GB heap
and 300-second protocol limit. Record #78's obligation to restore the gate.
Refs: #75, #78
Evaluate explicit, ordered optimization configurations through one shared
planner model. Add six editable presets, durable one-time legacy migration,
and consistent completed and cancelled plan provenance.
Include functional regressions and the agreed trace-removal and benchmark
follow-up specs. Performance acceptance remains in #78 under unchanged gates.
