The initiative warning becomes authored data, and staging gets a harness

Unreleased. The warning that v0.6.4 deleted is restored, but not as the
string heuristic that caused both faults — rosters carry beforeInitiative
now, and the renderers print it. 23 rosters have it: the 18 whose harmedBy
restricts what works, plus 5 Troll rosters that carried the instruction in
prose and so had two conventions between them. The prose copies are gone,
so it is said exactly once wherever it is said.

validate-pack enforces both halves — ONLY implies the field, and the phrase
may not appear in prose — and core/test.mjs now runs the validator over all
sixteen packs, so a pack regression fails the suite rather than waiting for
someone to remember the tool. Both rules were confirmed by breaking a pack
deliberately.

enter()'s decisions move to module/stage.mjs behind injected effects, which
makes the failure paths runnable under plain node. That immediately found a
bug in the first version of the extraction: Promise.resolve(fx.stage())
does not catch a synchronous throw, so a Forge that threw rather than
rejected would have taken the whole of enter() down. Nineteen of the new
tests are that matrix — failed scene, failed population with and without a
roster, failed hoard, failed cards, async rejection, and a Forge that
returns nothing.

The contract those tests hold: the scene is the commit point. Fail there
and nothing was entered, so a retry is safe; succeed and the turn advances
before anything else can fail, so a retry cannot restage. Everything after
degrades with a warning that says what was actually lost — the encounter
failure no longer promises a roster the area does not have, and the hoard
failure is no longer swallowed to the console.

Also: game.delve.loadPack is the validating resolver, so raiseDungeon can
no longer stage from a pack with no forgeStageType.
