Summary

• Capture the actual cast origin and trigger the supported exact “Whenever you cast a spell from your graveyard” clause only for the caster's permanents. Reuse existing effects, target selection, stack resolution, and persistence.
• Fix an absent optional regex capture in “each attacking creature” counters. The immutable main baseline fails imported-card validation on that warning; this patch fixes it without adding recognition coverage.
• Add real-card behavior tests and a hashed, reproducible corpus checkpoint. Preserve the separate enchanted/equipped family in Read "As long as CARDNAME is enchanted (equipped)" #327.

Validation

• PHP 8.4.24 local focused tests: 18 tests, 141 assertions passed (graveyard-cast plus attacking-counter tests).
• Final full suite with the local corpus enabled: 673 tests, 102,464 assertions passed, zero skips. This includes all focused cases and both corpus tests.
• Separately enabled corpus tests: 2 tests, 71,268 assertions passed, including all imported card parsing and 50 deterministic official-deck simulations.
• Full Pint and git diff --check passed.
• Independent source/test review found no blocking findings. Exact-head public CI is requested by this PR; no live bot testing or deployment.

Coverage evidence and limits

Same MTGJSON corpus 5.3.0+20261019 and unchanged importer for before/after:

• Modern recognized whole: 9,514 → 9,517 / 22,399 (42.5%).
• All imported pools recognized whole: 11,254 → 11,257 / 28,729 (39.2%).
• New wholly recognized pool entries: Secrets of the Dead, Burning Vengeance, Devoted Grafkeeper // Departed Soulkeeper. Tests cover the relevant behavior, including Grafkeeper front/back distinctions.

Recognition is not whole-card gameplay support. Most cards still have unsupported text, and the coverage task remains open. Ominous Roost's combined enter/cast clause deliberately remains unsupported. See docs/card-coverage-progress.md for corpus hashes, exact scope, tests, and remaining work.
