Fix Reflection abilities and Temporary Deathknell resolution

[abueide]

Problem and reproduction

LeBlanc Deceiver copies Honest Broker into a Temporary Reflection. When both die in one combat, only one Gold appears. The new regression reproduces 1 Gold instead of 2 before the fix. Temporary killing that Reflection also reproduces 0 Gold instead of 1.

The token's copied face already resolved its printed script while present. The bug was that the chain retained only a source ID and ability index: after the token despawned and a later request rebuilt the script cache, its queued ability had no implementation.

Fix

• Snapshot printed ability script identity centrally when pending items are enqueued, and use it throughout ordering/targeting/payment/resolution.
• Preserve same-request access to a departed token's last face while collecting its Deathknell.
• Refresh transformed static sources immediately, including copied auras and play restrictions.
• Keep copies as tokens and LeBlanc's separately granted Temporary; do not copy damage/buffs/attachments or replay Play triggers.
• Version plugin 0.9.1, blob 16. Prior supported blobs still decode; framework wire protocol is unchanged.

Ten regressions serialize state and rebuild scripts between actions. They cover combat, Temporary before Hold scoring, multi-stage Deathknell, movement, activation/keywords, queued abilities surviving another transformation, immediate auras, copying a copy, bounce without Deathknell, and Reckoner's Arena queuing a copied Conquer trigger. Independent review found the Arena bypass; the shared queue entry point and failing-then-passing regression address it.

Official rule source

Core Rules PDF — July 16, 2026, verified against the publisher's current rules hub: 477.1.b.1 (copyable traits/rules text), 808.1.c–d (Deathknell and last-known details), 816.1.b (Temporary kills before scoring).

Verification

• Rules library: 4,577 passed, 172 pre-existing ignores.
• Blob compatibility: 13 passed; match-state integration: 10 passed.
• Plugin library/projection: 10 passed.
• bash ci/check.sh and repository treefmt --ci: passed.
• Portable release plugin built and hardened successfully.
• Kai's companion dependency pin passed its fast checks and all-target compile.

Additional broad hardened replay check hits an existing Temporal Portal/Repeat payment fixture assertion at net/tests/riftbound_turns.rs:1156; reproduced identically using unchanged baseline 8765cdf and a separately rebuilt 0.9.0 plugin. Not changed here. Gas benchmarks are ignored by default and not counted as passing coverage. No manual GUI/network playtest or Android build.

Integration

Kai currently builds this Agni rules copy, not the extracted agni-rfb repository. A companion Kai PR pins this branch's commit and bumps Kai to 0.21.2. Merge this PR before that integration. Rebuild/harden bundled modules for release; existing matches stay pinned to their old plugin hash. Older snapshots cannot recover the script identity of a token that had already vanished before this fix.

Review follow-up

Removed duplicated legacy CBOR conversion from three card tests and moved serialized action/choice/resolution helpers onto the shared Fixture. Current row widths are read rather than hardcoded; stable v11 fields are named in one test module. Prompt-choice policy stays explicit in each scenario. Four additional fixture tests pass. This follow-up is test/documentation only; no runtime or schema changes.
