PF1e (SRD spells/sound-burst.md): "Every creature in the area takes 1d8 points of sonic damage and must succeed on a Fortitude save to avoid being stunned for 1 round" — the Fortitude partial negates the stun only, never the dice. The damage component declared half_on_save: true, halving the sonic damage on a successful save. DamageEffect gains a save_negates flag (default True, existing behavior unchanged); sound_burst.json declares half_on_save: false + save_negates: false so the 1d8 is full regardless while the condition keeps save_negates. README updated.

SpellSpec gains a cast_time field (seven budget codes; the JSON loader
also accepts RAW phrasings like "1 round" or "1 minute"). The pure
budget filters take a CastTimeResolver so a cast_spell occupies the slot
its casting time maps to: standard->standard, swift->swift (competing
with deed/inspire courage and dropped by a consumed immediate),
immediate/free->free, full_round and one_round->full_round (one_round
clamped: resolved end-of-turn, documented approximation), long->dropped
before the budget filter with the new downgraded:cast_time reason. The
engine binds its registry lookup via _cast_time_of (unknown names fall
back to standard, keeping transcripts byte-identical);
_choose_spell_action never selects long casts; the staggered filter now
drops full-round casts and spell_combat via the effective slot
(_FULL_ROUND_KINDS becomes dead and is deleted). Summon Monster I/II are
the only data spells marked 1 round. Metamagic full-round casting for
spontaneous casters is out of scope (future hook documented in
_cast_time_of).
