A Priest companion needs the same targeted-cast rules for bot and client requests. Actor cast requests previously admitted unlearned spells and had no shared line-of-sight Gate, so the Package could not turn a typed range or visibility refusal into safe movement before healing.

Add learned-spell and targeted line-of-sight Gates to the owning Actor request. The checks preserve self, untargeted, creature, and triggered cast behavior, and refuse unsupported channels before any cast state changes. Party facts now distinguish no membership from a membership whose Group row is unavailable. Fresh Shards seed Lesser Heal for a named ally; the existing post-publish repair changes only the exact former canonical definition.

The debug-only synchronous cast reducers still resolve staged fixture spells directly. Production Actor, client, and bot requests continue through the learned-spell Gate.

Validation:

• Clean Core b3bf5a7e91536c7dc2f7cfb90305e6d1f35889f6 and Package 87468ec4eaf2d63fdefe754c9edeb3ad65fc71d1 passed the full paired CI: companion 20/20, PB-001/PB-002 regressions 37/37, and library 1,633/1,633.
• Clean final Core 624edcdfde9c607a22c9ddc751b7c40caf6c7018 and Package 4741c973910a78127bf722bde274c79556b75306 passed the focused atomic-selection retention and populated PB-002 upgrade cases, 2/2. The full-union release Wasm with debug_reducers was 7,522,611 bytes with SHA-256 2e43ae814df3b4e472113736565c1bf263ce7a99cc41749660d09d37d526cf12.
• The retention record contains three distinct completed 1,000 ms movement splines before the cast starts at the retained ally. The populated upgrade preserves the exact pending 60-second cast and runner foreground state.
• Predecessor Wasm inputs have independent clean source and build manifests. Current and preceding builds use separate target directories in CI.

The visibility cases use an explicit seeded wall with synthetic provenance. They do not claim imported geometry or real-client acceptance. No production realm was accessed.

Implemented with GPT-5.6 Sol in Codex. GPT-6 handled orchestration and independent review.

📝 Walkthrough

Walkthrough

The change adds cast-readiness and line-of-sight validation, exposes party facts, expands companion integration coverage, and corrects canonical Lesser Heal targeting with guarded repair support.

Changes

Companion casting and party-facts updates

Layer / File(s)	Summary
Cast readiness and targeted casting gates docs/package-api.md, module/src/actor.rs, module/src/spell/..., module/src/debug/mod.rs, module/src/gw.rs	Character casts now validate spellbook membership and line of sight. Pending casts recheck line of sight before resolution. Creature, triggered, self-targeted, and untargeted casts retain their exemptions.
Party facts and companion lifecycle coverage CONTEXT.md, module/src/group.rs, module/tests/playerbots_companion.rs, module/tests/playerbots_rewrite/runner.rs	The new group::party_facts API reports durable membership and nullable live unit facts. Integration tests cover movement, retained objectives, healing, recovery, cancellation, death, regrouping, and runner-state upgrades.
Cast refusal and exemption coverage module/tests/playerbots_companion.rs	Integration tests verify line-of-sight and unlearned-spell refusals, supported cast lifecycles, and exemptions for self, untargeted, triggered, and creature casts.
Lesser Heal seed and repair handling module/src/seed.rs, module/src/debug/repair.rs, module/tests/playerbots_companion.rs	Lesser Heal targets an ally. The guarded repair updates only matching legacy rows and preserves changed definitions.
